While witnessing violence between parents is one of the most consistent correlates of experiencing intimate partner violence (IPV) in later life, little research exists in developing countries on the effects of witnessing interparental IPV on young adults' involvement with family violence. This study examines the relation between witnessing interparental IPV and young adults' subsequent use and experience with family intimidation and physical abuse (FIPA) in Cebu, Philippines. Using data from the Cebu Longitudinal Health and Nutrition Survey, recent use and experience of FIPA among 21-22 year old young adults was assessed through self-reports from the 2005 survey, and childhood witnessing of interparental IPV assessed from the 2002 survey. Multinomial logistic regression was used to examine the effect of witnessing interparental IPV on young adults' use and experience of FIPA. Among all young adults, witnessing paternal perpetration of IPV predicted using FIPA, and witnessing maternal perpetration predicted experiencing FIPA. Among young adult females only, witnessing reciprocal IPV between parents predicted experiencing FIPA. Witnessing paternal perpetration of IPV among young adult males, maternal perpetration among young adult females, and reciprocal interparental IPV among all young adults predicted young adults both using and experiencing FIPA. Violence prevention efforts should reach all family members through family centered interventions. School based curricula, which largely focus on intimate partner and peer violence, should recognize adolescents' use and experience of violence with family members, and design modules accordingly. Further research on gender differences in family violence is recommended.

We conducted longitudinal analyses examining the associations between intimate partner violence (IPV) attitudes and women’s reported IPV in couples (N = 762) using 3 waves of data from a randomized controlled trial in Maharashtra, India. We found that, between Waves 1 and 2, men’s and women’s acceptance of IPV in the overall population decreased significantly while reports of IPV increased. These changes, we hypothesize, are evidence of an exogenous shock, possibly a high profile rape in Delhi in December 2012, that may have impacted the entire population. Cross-sectional associations between men’s attitudes towards IPV and reported IPV were not significant in Wave 1, while positively and significantly associated in Waves 2 and 3. Longitudinal analysis showed that reduction in men’s acceptance of IPV between Waves 1 and 2 was associated with a lower likelihood of reported IPV in Wave 3. Women’s Wave 1 acceptance of IPV was positively associated with reported IPV in the Wave 1 cross-sectional analysis, while Wave 2 and Wave 3 measures of IPV acceptance were negatively associated with reported IPV in Waves 2 and 3 respectively. Longitudinal analyses of the change in women’s attitudes towards IPV from Wave 1 to 2 and reported IPV in Wave 3 were insignificant. However, When women first reported IPV in Waves 2 or 3 they were less likely to report acceptance of IPV in that same wave. Findings suggest that changes in husbands’ IPV acceptance is predictive of subsequent IPV, while newly experienced IPV predicts decreased IPV acceptance for women. Wave 2 and Wave 3 results were significant for the control group only, evidence that the intervention affected those associations, potentially changing attitudes more quickly than behavior. We recommend interventions that expose community opposition to IPV as a new social norm, and analysis of how the 2012 Delhi rape case may have affected these norms. PMID:28260640

We examined the potential association between African couples' concordance on attitudes toward violence (ATV) and risk for intimate partner violence (IPV). Analyses included 13,837 couples from Demographic and Health Surveys conducted between 2003 and 2007, from six African countries. Concordance on ATV was defined as both spouses justifying physical abuse, and IPV was defined as incidence of a physically violent act against the wife. We constructed a concordance measure from the surveys to assess overall and country-level differences in couple's ATV concordance rates and assessed the association between concordance in ATV and IPV using hierarchical regression modeling that adjusted for multilevel influences on risk estimates. Negative concordance (perfect agreement in negative ATV) was used as referent category in all analyses. Overall, spousal ATV concordance was associated with higher likelihood for IPV (adjusted odds ratio [AOR] = 2.27, 95% confidence interval [CI] = [2.01, 2.56]). The level of wealth, educational attainment, rural/urban residence, presence of a cowife, religion, maternal age, and parity were characteristics that predicted the occurrence of IPV within couples. Spousal ATV concordance was significantly associated with violence in every African nation included in the analysis except Rwanda. African couples with high rates of ATV concor- dance experience higher risks for IPV, with some variation in magnitude of risk across countries. In African settings, ATV positive concordance could serve as a supplemental screening tool to detect spousal violence. Understanding ATV could potentially enhance our ability to formulate public health intervention to detect and prevent spousal abuse.

The Role of Alcohol Policies in Preventing Intimate Partner Violence: A Review of the Literature

Kearns, Megan C.; Reidy, Dennis E.; Valle, Linda Anne

2015-01-01

Objective This article summarizes existing research on the relationship between alcohol policies and intimate partner violence (IPV). Because alcohol represents an important risk factor for IPV, interventions and policies aimed at decreasing problem drinking may also lead to reductions in IPV. Method Electronic databases were searched to identify relevant peer-reviewed journal articles on alcohol policies and IPV, as well as reference sections of appropriate articles. Only policies that have been studied specifically for impact on IPV were included. Results Three alcohol policy areas (outlet density, hours and days of sale, pricing/taxation) had been studied in relation to IPV outcomes. Research on outlet density had the most consistent findings, with most studies indicating that higher densities of alcohol outlets are associated with higher rates of IPV. Fewer studies had been conducted on pricing policies and policies restricting hours/days of sale, with most studies suggesting no impact on IPV rates. Conclusions Higher density of alcohol outlets appears to be associated with greater rates of IPV. However, there is limited evidence suggesting that alcohol pricing policies and restrictions on hours/days of sale are associated with IPV outcomes. Knowledge about the impact of alcohol-related policies on IPV and violence in general is limited by several significant research gaps. Additional research is needed to assess the impact of alcohol policies on IPV and other forms of violence. PMID:25486390

Although intimate partner violence (IPV) is a well-known risk for child maltreatment, little is known if the prevalence of and risk factors for IPV differ among US-born and foreign-born families involved with Child Protective Services. Data came from a new cohort of the National Survey of Child and Adolescent Well-Being II (NSCAW II), a national probability study of children reported for child abuse and neglect. The study sample was restricted to female caregivers whose children remained in the home following an investigation (N=2,210). Caregiver self-report information was used to measure physical form of IPV during the past 12 months. The study results revealed no significant differences in IPV victimization rates between foreign-born and US-born caregivers both bivariately and while controlling for key socio-demographic and psychosocial functioning characteristics as well as family needs. Common risk factors for both population groups included caregiver’s young age, depression, high family stress and low social support. Additionally, foreign-born caregivers were more likely to experience IPV when there was high neighborhood stress and intimate partner was absent while Hispanic ethnicity, higher education, problematic substance use, and difficulty with paying for basic necessities predicted IPV among US-born caregivers. Neither legal status nor acculturation indicators were significantly associated with IPV victimization for foreign-born. Findings indicate that IPV remains a significant problem for child welfare-involved caregivers and warrant effective screening, identification and prevention. PMID:26085705

Stress in the City: Influence of Urban Social Stress and Violence on Pregnancy and Postpartum Quality of Life among Adolescent and Young Mothers.

Adolescent and young mothers transitioning from pregnancy to postpartum need to maintain an optimal quality of life. Stress and exposure to violence (e.g., intimate partner violence (IPV), nonpartner violence) are predictors of poor quality of life for adult women; however, these associations remain understudied among adolescent and young mothers in urban areas. Guided by the social ecological model, the current study created a latent variable, urban social stress, to examine the impact of the urban social environment (i.e., stressful life events, discrimination, family stress, and neighborhood problems) on the quality of life of adolescent and young mothers during both pregnancy and postpartum. The current study is a secondary data analysis of a prospective cohort study of 296 expectant young mothers recruited at obstetrics and gynecology clinics. Results from structural equation and multigroup models found that higher urban social stress predicted lower mental and physical quality of life during pregnancy, but these associations were significantly stronger for IPV-exposed and nonpartner violence-exposed mothers. In the postpartum period, higher urban social stress predicted lower mental and physical quality of life, but these associations were significantly stronger for IPV-unexposed and nonpartner violence-exposed mothers. Stress reduction programs need to help adolescent and young mothers in urban areas develop stress management skills specific to urban social stress. Pregnancy and parenting programs need to be tailored to the specific needs of young mothers in urban areas by becoming sensitive to the role of IPV and nonpartner violence in these young women's lives.

This study analyzes whether there are time patterns in different intimate partner violence (IPV) indicators and aims to obtain models that can predict the behavior of these time series. Univariate autoregressive moving average models were used to analyze the time series corresponding to the number of daily calls to the 016 telephone IPV helpline and the number of daily police reports filed in the Community of Madrid during the period 2008-2015. Predictions were made for both dependent variables for 2016. The daily number of calls to the 016 telephone IPV helpline decreased during January 2008-April 2012 and increased during April 2012-December 2015. No statistically significant change was observed in the trend of the number of daily IPV police reports. The number of IPV police reports filed increased on weekends and on Christmas holidays. The number of calls to the 016 IPV help line increased on Mondays. Using data from 2008 to 2015, the univariate autoregressive moving average models predicted 64.2% of calls to the 016 telephone IPV helpline and 73.2% of police reports filed during 2016 in the Community of Madrid. Our results suggest the need for an increase in police and judicial resources on nonwork days. Also, the 016 telephone IPV helpline should be especially active on work days.

Attention-deficit/hyperactivity disorder (ADHD) is associated with interpersonal dysfunction during childhood and adolescence, yet little is known about the romantic relationships of young women with childhood ADHD. In the present study, we draw from a longitudinal sample of girls followed prospectively into young adulthood, comparing those with (n = 114) and without (n = 79; comparisons) childhood ADHD in terms of their risk for physical victimization by an intimate partner (physical IPV; e.g., slapping, punching) by 17–24 years of age. We examined ADHD both diagnostically and dimensionally, at the same time establishing reliable indicators of young adult physical IPV. Externalizing and internalizing problems, and academic achievement during adolescence, were tested as potential mediators. Overall, participants with a childhood diagnosis of ADHD experienced more physical IPV than did comparisons (30.7% vs. 6.3%). In parallel, IPV was associated with higher levels of childhood ADHD symptomatology (d = .73). Young women with persistent ADHD stood the highest risk of experiencing IPV (37.3%), followed by those with transient ADHD (19.0%) and those never-diagnosed (5.9%). Academic achievement measured during adolescence was a significant partial mediator of the childhood ADHD symptomatology-young adult IPV relationship, even with control of sociodemographic, psychiatric, and cognitive factors, including childhood reading and math disorders. Findings indicate that in young women, childhood ADHD is a specific and important predictor of physically violent victimization in their intimate relationships. This vulnerable population requires IPV prevention and intervention, with academic empowerment as a key target. PMID:25663589

2015-01-01

Although intimate partner violence (IPV) has demonstrated strong associations with anxiety and posttraumatic stress, these constructs have rarely been examined simultaneously in IPV research. Gaps in knowledge remain as to their differential associations to substance use problems among IPV-victimized women. A sample of 143 community women self-reported on their current IPV victimization, mental health and substance use problems. Hierarchical entry multiple regressions were used to test for the direct and indirect effects of psychological, physical, and sexual IPV to alcohol and drug problems through anxiety and posttraumatic stress. Higher anxiety symptom severity and higher physical IPV severity were associated with greater alcohol and drug problems. Higher posttraumatic stress symptom severity was associated with greater alcohol and drug problems. Mediation analyses indicated (i) significant indirect pathways of IPV types to alcohol problems through posttraumatic stress symptom severity controlling for anxiety symptom severity and (ii) significant indirect pathways of IPV types to drug problems through anxiety symptom severity controlling for posttraumatic stress symptom severity. In examining the indirect pathways of psychological, physical, and sexual IPV to substance use problems this study highlights that anxiety and posttraumatic stress symptom severity have unique effects on alcohol and drug problems among IPV-victimized women.

Subjective Sleep Quality in Women With Divorce Histories: The Role of Intimate Partner Victimization.

Newton, Tamara L; Burns, Vicki Ellison; Miller, James J; Fernandez-Botran, G Rafael

2016-05-01

A marital status of divorced or separated, as opposed to married, predicts increased risk of health problems, but not for all persons. Focusing on one established health risk that has been linked with divorce--poor subjective sleep quality--the present cross-sectional study examined whether a history of physical intimate partner victimization (IPV) helps identify divorced women at potentially greater risk of health problems. Community midlife women with divorce histories, all of whom were free of current IPV, reported on their past month sleep quality and lifetime IPV. The predicted odds of poor sleep quality were significantly greater for women with, versus without, IPV histories. This held after adjusting for socioemotional, medical, or sociodemographic risks. A dose-response relationship between IPV chronicity and poor quality sleep was observed. IPV history may help identify divorced women at increased risk of poor quality sleep and, more broadly, poor health. © The Author(s) 2015.

Does economic empowerment protect women from intimate partner violence?

The current study compared working and non-working groups of women in relation to intimate partner violence. The paper aims to explore the relationship between women's economic empowerment, their exposures to IPV and their help seeking behavior using a nationally representative sample in India. This was a cross sectional study of 124,385 ever married women of reproductive age from all 29 member states in India. Chi-square tests were used to examine differences in proportions of dependent variables (exposure to IPV) and independent variables. Multivariate logistic regressions were used to assess the independent contribution of the variables of economic empowerment in predicting exposure to IPV. Out of 124,385 women, 69432 (56%) were eligible for this study. Among those that were eligible 35% were working. In general, prevalence of IPV (ever) among women in India were: emotional violence 14%, less severe physical violence 31%, severe physical violence 10% and sexual violence 8%. For working women, the IPV prevalence was: emotional violence 18%, less severe physical violence 37%, severe physical violence 14% and sexual violence 10%; whilst for non-working women the rate was 12, 27, 8 and 8 percents, respectively. Working women seek more help from different sources. Economic empowerment is not the sole protective factor. Economic empowerment, together with higher education and modified cultural norms against women, may protect women from IPV. ‎

Antibody responses of Macaca fascicularis against a new tetravalent vaccine composed of diphtheria toxoid, tetanus toxoid, acellular pertussis antigens, and inactivated poliovirus derived from Sabin strains (sIPV) was investigated to predict an optimal dose of sIPV in a new tetravalent vaccine (DTaP-sIPV) prior to conducting a dose-defined clinical study. Monkeys were inoculated with DTaP-sIPVs containing three different antigen units of sIPVs: Vaccine A (types 1:2:3 = 3:100:100 DU), Vaccine B (types 1:2:3 = 1.5:50:50 DU), and Vaccine C (types 1:2:3 = 0.75:25:25 DU). There was no difference in the average titers of neutralizing antibody against the attenuated or virulent polioviruses between Vaccines A and B. The average neutralizing antibody titers of Vaccine C tended to be lower than those of Vaccines A and B. The sIPV antigens did not affect the anti-diphtheria or anti-tetanus antibody titers of DTaP-sIPV. Furthermore, the average neutralizing antibody titers of Vaccine A against the attenuated and virulent polioviruses were comparable between M. fascicularis and humans. These results suggest that M. fascicularis may be a useful animal model for predicting the antibody responses to sIPVs in humans, and that it may be likely to reduce the amount of sIPVs contained in DTaP-sIPVs, even for humans.

Recovery from depressive symptoms, state anxiety and post-traumatic stress disorder in women exposed to physical and psychological, but not to psychological intimate partner violence alone: A longitudinal study

PubMed Central

2010-01-01

Background It is well established that intimate male partner violence (IPV) has a high impact on women's mental health. It is necessary to further investigate this impact longitudinally to assess the factors that contribute to its recovery or deterioration. The objective of this study was to assess the course of depressive, anxiety and post-traumatic stress disorder (PTSD) symptoms and suicidal behavior over a three-year follow-up in female victims of IPV. Methods Women (n = 91) who participated in our previous cross-sectional study, and who had been either physically/psychologically (n = 33) or psychologically abused (n = 23) by their male partners, were evaluated three years later. A nonabused control group of women (n = 35) was included for comparison. Information about mental health status and lifestyle variables was obtained through face-to-face structured interviews. Results Results of the follow-up study indicated that while women exposed to physical/psychological IPV recovered their mental health status with a significant decrease in depressive, anxiety and PTSD symptoms, no recovery occurred in women exposed to psychological IPV alone. The evolution of IPV was also different: while it continued across both time points in 65.21% of psychologically abused women, it continued in only 12.12% of physically/psychologically abused women while it was reduced to psychological IPV in 51.5%. Hierarchical multiple regression analyses indicated that cessation of physical IPV and perceived social support contributed to mental health recovery, while a high perception of lifetime events predicted the continuation of PTSD symptoms. Conclusion This study shows that the pattern of mental health recovery depends on the type of IPV that the women had been exposed to. While those experiencing physical/psychological IPV have a higher likelihood of undergoing a cessation or reduction of IPV over time and, therefore, could recover, women exposed to psychological IPV alone have a high probability of continued exposure to the same type of IPV with a low possibility of recovery. Thus, women exposed to psychological IPV alone need more help to escape from IPV and to recuperate their mental health. Longitudinal studies are needed to improve knowledge of factors promoting or impeding health recovery to guide the formulation of policy at individual, social and criminal justice levels.

Intimate Partner Violence, Police Involvement, and Women's Trauma Symptoms.

PubMed

Rancher, Caitlin; Jouriles, Ernest N; McDonald, Renee

2018-06-01

This study examined whether police involvement in intimate partner violence (IPV) incidents is associated with women's trauma symptoms. Participants were 95 women recruited from domestic violence shelters. Women reported on their trauma symptoms, the frequency of IPV victimization, the use of a weapon during IPV, and police involvement over the year following shelter departure. Police involvement in IPV was associated with higher levels of reexperiencing trauma symptoms 1 year after shelter departure, even after controlling for baseline trauma symptoms, the frequency of IPV, and the use of a weapon during IPV. Women's race and ethnicity did not moderate the results. These findings suggest police involvement in IPV incidents may be associated with higher levels of trauma symptoms experienced by women. Further investigation into law enforcement practices and policies to help reduce women's distress is needed.

Background Intimate partner violence (IPV) is a global problem that affects one-third of all women. The present study aims to develop and determine the validity of a screening instrument for the detection of IPV in pregnant women in Tanzania and Vietnam and to determine the minimum number of questions needed to identify IPV. Method An IPV screening instrument based on eight questions was tested on 1,116 Tanzanian and 1,309 Vietnamese women who attended antenatal care before 24 gestational weeks. The women were re-interviewed during their 30th-34th gestational week where the World Health Organization (WHO) IPV questionnaire was used as the gold standard. In all, 255 combinations of eight different questions were first tested on the Tanzanian study population where sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated. In the evaluation of the performance of the question combinations, different IPV types and the frequency of abusive acts were considered. The question combinations that performed best in Tanzania were subsequently evaluated in the Vietnamese study population. Results In Tanzania, a combination of three selected questions including one question on emotional IPV, one on physical IPV and one on sexual IPV was found to be most effective in identifying women who are exposed to at least one type of IPV during pregnancy (sensitivity = .80; specificity = .74). The performance of the identified combination was slightly less effective in Vietnam (sensitivity = .74; specificity = .68). Focusing on different IPV types, the best performance was found for exposure to physical IPV in both Tanzania (sensitivity = .93; specificity = .70) and Vietnam (sensitivity = .96; specificity = .55). In both countries, the sensitivity increased with the frequency of abuse whereas the specificity decreased. Conclusion By asking pregnant women three simple questions we were able to identify women who were exposed to IPV during pregnancy in two different countries. The question combination performed best in assessing physical IPV where it identified 93% and 96% of Vietnamese and Tanzanian women, respectively, who were exposed to physical IPV. PMID:29389954

Relative Importance of Emotional Dysregulation, Hostility, and Impulsiveness in Predicting Intimate Partner Violence Perpetrated by Men in Alcohol Treatment

The current study employs dominance analysis to assess the relative importance of three constructs—hostility, impulsiveness, and emotional dysregulation (difficulties managing one’s emotions when experiencing negative emotion or distress)—in explaining psychological, physical, and sexual intimate partner violence (IPV) perpetration by men seeking alcohol treatment. A sample of 121 predominantly White, heterosexual men (average age 33.28, range = 18 - 62) enrolled in residential substance abuse treatment completed measures of emotional dysregulation, hostility, and impulsiveness, which are three highly related constructs identified as risk factors for both substance use disorders and IPV. The constructs collectively accounted for 20-25% of the variance in each form of IPV. Because impulsiveness, hostility, and emotional dysregulation are highly correlated, dominance analysis was used to examine which factor most strongly predicted each form of IPV. Dominance analysis findings favored hostility as a predictor of physical IPV perpetration, and impulsiveness as a predictor of sexual and psychological IPV perpetration. Differential associations between the constructs and each form of IPV may be used to inform assessment and treatment planning of men who abuse alcohol. Better understanding, preventing, and treating male-to-female IPV will protect women from the far-reaching consequences of this violence. PMID:23990693

Intimate partner violence among women with eating disorders during the perinatal period

ABSTRACT Objective  Prevalence of intimate partner violence (IPV) during pregnancy is estimated to be 4%–8%. Women with mental health difficulties are at increased risk for IPV during the perinatal period. Prevalence of IPV is high among women with eating disorders (ED); however, prevalence of IPV during the perinatal period among women with ED is unknown. Method  We studied women from a population‐based cohort, the Avon Longitudinal Study of Parents and Children. Prevalence and odds of physical and emotional IPV during and after the perinatal period was investigated among women with lifetime ED, with (n = 174) or without pregnancy shape and weight concern and/or purging behaviors (n = 189), and women with no ED (n = 8723). Results  Women with lifetime ED showed higher prevalence of IPV during and after the perinatal period (physical = 9.6%–14.3% and emotional = 24.1%–28.1%). Lifetime ED was associated with higher odds of physical IPV during the perinatal period (odds ratio: 2.34, 95% confidence interval: 1.11–4.93, p = .03). Lifetime ED with and without pregnancy shape and weight concerns and/or purging was associated with higher odds of IPV after the perinatal period, and higher odds of reporting emotional IPV at all time points. Associations were moderated by partner's response to pregnancy and maternal experience of childhood sexual abuse. Discussion  Mothers with ED and their children may be vulnerable to negative effects due to maternal ED and IPV combined, both of which have been associated with severe and long‐lasting harmful consequences. Partner's response to pregnancy and maternal experience of childhood sexual abuse might contribute to the association between ED and IPV perinatally. © 2015 The Authors.

2013-08-01

The article estimates the prevalence and sociodemographic correlates of intimate partner violence (IPV) by type and severity in population-based samples from three countries of the former Soviet Union (fSU). The article utilized nationally representative data from the Demographic and Health Surveys (DHS) conducted in Azerbaijan (2006), Moldova (2005), and Ukraine (2007). Respondents were selected using stratified multistage cluster sampling. The sample included ever-married (or cohabitating) females of reproductive age (15-49 years old); weighted sample n = 3,847 in Azerbaijan, n = 4,321 in Moldova, and n = 2,355 in Ukraine. The analysis used multinomial survey logistic regression adjusting for the sampling design and sampling weights. Ten percent of ever-partnered women in Azerbaijan and Ukraine and 20% in Moldova ever experienced physical IPV (without sexual) from their most recent husband or cohabitating partner; 3% of women in Azerbaijan and Ukraine and 5% in Moldova experienced sexual IPV (with or without physical), and 2% of women in Azerbaijan, 3% in Ukraine, and 6% in Moldova experienced violence resulting in severe physical injuries from their most recent partner. In all three countries physical, sexual, and injurious IPV was higher among formerly married women. Compared to women with above secondary education, women with secondary education or below demonstrated higher risk for physical IPV (in Moldova and Ukraine), sexual IPV in Moldova, and injurious IPV in all three countries. Poor socioeconomic status-as indicated by low household wealth status in Azerbaijan and partner's unemployment in Moldova and Ukraine-was significantly associated with higher risk for physical and injurious IPV. In Moldova and Ukraine partners' low level of education was associated with higher risk for sexual IPV. The article demonstrates that experiences and factors associated with IPV are diverse and context specific. The findings may be helpful in targeting interventions to sociodemographic groups disproportionately affected by IPV in these three transitional countries.

Experience of intimate partner violence (IPV) can have adverse health impacts and has been associated with elevated rates of healthcare service utilization. Healthcare encounters present opportunities to identify IPV-related concerns and connect patients with services. The Veterans Health Administration (VHA) conducts IPV screening within an integrated healthcare system. The objectives of this study were to compare service utilization in the 6 months following IPV screening between those screening positive and negative for past-year IPV (IPV+, IPV-) and to examine the timing and types of healthcare services accessed among women screening IPV+. A retrospective chart review was conducted for 8888 female VHA patients across 13 VHA facilities who were screened for past-year IPV between April 2014 and April 2016. Demographic characteristics (age, race, ethnicity, marital status, veteran status), IPV screening response, and healthcare encounters (based on visit identification codes). In the 6 months following routine screening for past-year IPV, patients screening IPV+ were more likely to utilize outpatient care (aOR = 1.85 [CI 1.26, 2.70]), including primary care or psychosocial care, and to have an inpatient stay (aOR = 2.09 [CI 1.23, 3.57]), compared with patients screening IPV-. Among those with any utilization, frequency of outpatient encounters within the 6-month period following screening was higher among those screening IPV+ compared with those screening IPV-. The majority of patients screening positive for past-year IPV returned for an outpatient visit within a brief time frame following the screening visit (> 70% within 14 days, >95% within 6 months). More than one in four patients screening IPV+ had an emergency department visit within the 6 months following screening. Women who screen positive for past-year IPV have high rates of return to outpatient visits following screening, presenting opportunities for follow-up support. Higher rates of emergency department utilization and inpatient stays among women screening IPV+ may indicate adverse health outcomes related to IPV experience.

HIV has an impact on the presence and severity of both intimate partner violence (IPV) and posttraumatic stress disorder (PTSD) in infected women. However, the relationship of type and severity of IPV with PTSD in this population has not been adequately explored. We focus on the association between the type and severity of IPV and HIV status and PTSD in a sample of South African women. One hundred and sixty-nine women (114 HIV-positive and 55 HIV-negative controls), matched for geographical area, education, and socio-economic status, were recruited from HIV clinics. Clinical and demographic data were collected, including data on childhood trauma, other traumatic life events, IPV, posttraumatic stress symptoms, problematic alcohol use, and depressive symptoms. HIV-positive women had significantly more depressive symptoms, alcohol abuse, and childhood trauma exposure as well as significantly higher rates of PTSD (25.4%) when compared with uninfected women (10.9%). No significant group differences in the rate, pattern, and severity of physical, sexual, psychological, injury, and negotiation IPV were found. In logistic regression analysis, the rate and severity category of IPV did not significantly predict PTSD in HIV-positive women when childhood trauma and life events were controlled for. Our results indicate the need for screening for alcohol abuse, PTSD and depressive symptoms at HIV wellness, and ARV clinics. The high rates of PTSD in HIV-positive women indicate the need for specialized programs to manage PTSD and minimize negative sequelae in this population. These results also highlight the need for improved screening and prevention of childhood trauma and IPV both in infected and uninfected women.

This paper describes the extent to which abused and neglected children report intimate partner violence (IPV) victimization and perpetration when followed up into middle adulthood. Using data from a prospective cohort design study, children (ages 0–11) with documented histories of physical and sexual abuse and/or neglect (n = 497) were matched with children without such histories (n = 395) and assessed in adulthood (Mage = 39.5). Prevalence, number, and variety of four types of IPV (psychological abuse, physical violence, sexual violence, and injury) were measured. Over 80% of both groups–childhood abuse and neglect (CAN) and controls–reported some form of IPV victimization during the past year (most commonly psychological abuse) and about 75% of both groups reported perpetration of IPV toward their partner. Controlling for age, sex, and race, overall CAN [adjusted odds ratio (AOR) = 1.60, 95% CI [1.03, 2.49], physical abuse (AOR = 2.52, 95% CI [1.17, 5.40]), and neglect (AOR = 1.64, 95% CI [1.04, 2.59]) predicted increased risk for being victimized by a partner via physical injury. CAN and neglect also predicted being victimized by a greater number and variety of IPV acts. CAN and control groups did not differ in reports of perpetration of IPV, although neglect predicted greater likelihood of perpetrating physical injury to a partner, compared to controls. Abused/neglected females were more likely to report being injured by their partner, whereas maltreated males did not. This study found that child maltreatment increases risk for the most serious form of IPV involving physical injury. Increased attention should be paid to IPV (victimization and perpetration) in individuals with histories of neglect. PMID:24325940

Intimate partner violence (IPV) is a significant public health problem in South Africa. However, there is limited research on whether and how IPV changes during pregnancy and the postpartum period and on the factors that might affect women's risk during this time. In this study, we describe the mean trajectories of physical and psychological IPV during pregnancy and the postpartum period and examine whether relationship power, partner social support, and relationship stress are associated with women's trajectories of IPV. Data come from a longitudinal study with 1,480 women recruited during pregnancy between May 2008 and June 2010 at a public clinic in Durban. Women completed behavioral assessments at their first antenatal visit, at fourteen weeks and at nine months postpartum. Women's experiences of IPV were measured at all three time points and relationship power, partner social support and relationship stress were each measured at the baseline assessment. We used multilevel random coefficients growth modeling to build our models. The mean trajectory for both types of IPV was flat which means that, on average, there was not significant change in levels of IPV over pregnancy and the postpartum period. However, there was significant individual variability in trajectories of IPV over the study period. Women who had higher relationship power had lower levels of physical and psychological IPV over time than women with lower relationship power. Additionally, women with higher relationship stress and lower partner support had higher levels of psychological IPV at pregnancy. Interventions that maximize women's relationship power and partner social support and minimize relationship stress during this transformative time are needed. PMID:25268363

Disentangling the risk assessment and intimate partner violence relation: Estimating mediating and moderating effects.

PubMed

Williams, Kirk R; Stansfield, Richard

2017-08-01

To manage intimate partner violence (IPV), the criminal justice system has turned to risk assessment instruments to predict if a perpetrator will reoffend. Empirically determining whether offenders assessed as high risk are those who recidivate is critical for establishing the predictive validity of IPV risk assessment instruments and for guiding the supervision of perpetrators. But by focusing solely on the relation between calculated risk scores and subsequent IPV recidivism, previous studies of the predictive validity of risk assessment instruments omitted mediating factors intended to mitigate the risk of this behavioral recidivism. The purpose of this study was to examine the mediating effects of such factors and the moderating effects of risk assessment on the relation between assessed risk (using the Domestic Violence Screening Instrument-Revised [DVSI-R]) and recidivistic IPV. Using a sample of 2,520 perpetrators of IPV, results revealed that time sentenced to jail and time sentenced to probation each significantly mediated the relation between DVSI-R risk level and frequency of reoffending. The results also revealed that assessed risk moderated the relation between these mediating factors and IPV recidivism, with reduced recidivism (negative estimated effects) for high-risk perpetrators but increased recidivism (positive estimate effects) for low-risk perpetrators. The implication is to assign interventions to the level of risk so that no harm is done. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Prevalence of traumatic brain injury in intimate partner violence offenders compared to the general population: a meta-analysis.

Farrer, Thomas J; Frost, R Brock; Hedges, Dawson W

2012-04-01

Intimate partner violence (IPV) is widespread. Several risk factors are associated with IPV perpetuation, including alcohol use and educational level. The aggression and violence associated with traumatic brain injury (TBI) suggest that brain trauma may also be a risk factor for IPV. To examine the association between TBI and IPV, the authors conducted a meta-analysis of peer-reviewed published studies reporting the prevalence of TBI in IPV perpetrators. The authors compared the frequency of TBI among IPV perpetuators to estimates of TBI in the general population using a single-sample test of proportions. Six studies containing a total of 222 subjects met inclusion criteria. Fifty-three percent (119) of the IPV perpetuators had a history of TBI, a prevalence significantly higher (p < .0001) than estimates of TBI in the general population. The prevalence of TBI among perpetuators of IPV appears significantly higher than the prevalence of TBI in the general population. To the extent that this association is causal, TBI may be a risk factor for interpersonal violence, although comparatively few source studies, lack of standardized information about TBI severity, and the inability to investigate potential confounding variables necessarily limit this conclusion.

We wanted to prospectively evaluate the use of a brief screening tool for ongoing intimate partner violence (IPV), the OVAT, and to validate this tool against the present Index of Spouse Abuse (ISA). The design was a prospective survey during randomized 4-hour shifts in an urban emergency department setting. The scale consists of four questions developed based on our previous work. The ISA was compared as the gold standard for detection of present (ongoing) IPV. Of 362 eligible patients presenting during 75 randomized 4-hour shifts, 306 (85%) completed the study. The prevalence of ongoing IPV using the OVAT was 31% (95% CI 26% to 36%). For the ISA, the prevalence was 20% (95% CI 16% to 25%). Compared with the ISA, the sensitivity of the OVAT in detecting ongoing IPV was 86%, specificity 83%, negative predictive value 96%, positive predictive value 56%, with an accuracy of 84%. In conclusion, four brief questions can detect ongoing IPV to aid in identifying the victim.

Intimate partner violence (IPV) is a global public health problem that affects women's physical, mental, sexual and reproductive health. Very little data on IPV experience and FP use is available in resource-poor settings, such as in West Africa. The aim of this study was to describe the prevalence, patterns and correlates of IPV among clients of an adult Family Planning clinic in Conakry, Guinea. The study data was collected for four months (March to June 2014) from women's family planning charts and from an IPV screening form at the Adult Family Planning and Reproductive Health Clinic of "Association Guinéenne pour le Bien-Etre Familial", a non-profit organization in Conakry, Guinea. 232 women out of 245 women who attended the clinic for services during the study period were screened for IPV and were included in this study. Of the 232 women screened, 213 (92%) experienced IPV in one form or another at some point in their lifetime. 169 women reported psychological violence (79.3%), 145 reported sexual violence (68.1%) and 103 reported physical violence (48.4%). Nearly a quarter of women reported joint occurrence of the three forms of violence(24%).Half of the IPV positive women were current users of family planning (51.2%) and of these, 77.9% preferred injectable contraceptives. The odds of experiencing IPV was higher in women with secondary or vocational level of education than those with higher level of education (AOR: 8.4; 95% CI 1.2-58.5). Women residing in other communes of Conakry (AOR: 5.6; 95% CI 1.4-22.9) and those preferring injectable FP methods (AOR: 4.5; 95% CI 1.2-16.8) were more likely to experience lifetime IPV. IPV is prevalent among family planning clients in Conakry, Guinea where nine out of ten women screened in the AGBEF adult clinic reported having experienced one or another type of IPV. A holistic approach that includes promotion of women's rights and gender equality, existence of laws and policies is needed to prevent and respond to IPV, effective implementation of policies and laws, and access to quality IPV services in Guinea and countries with higher rates of IPV.

Family Functioning and Children's Post-Traumatic Stress Symptoms in a Referred Sample Exposed to Interparental Violence.

Telman, Machteld D; Overbeek, Mathilde M; de Schipper, J Clasien; Lamers-Winkelman, Francien; Finkenauer, Catrin; Schuengel, Carlo

This study examined the association between interparental violence (IPV), child abuse and neglect, other traumatic experiences, and children's post-traumatic stress (PTS) symptoms and explored the moderating role of family functioning in the aftermath of IPV. One hundred and twenty IPV-exposed children (53.3 % male, M age = 9.85) and parents who were referred to community mental health centers participated in the study. Combined, IPV, child abuse and neglect, and other traumatic experiences were associated with PTS symptoms. For family functioning, higher levels of parenting stress were associated with higher levels of PTS symptoms. No moderating effects were found. To understand the variability in PTS symptoms among children exposed to IPV, other traumatic and stressful experiences need to be taken into account.

Intimate Partner Violence among Men Who Have Sex with Men: A Systematic Review

2014-01-01

This article presents results from a systematic review of the literature on intimate partner violence (IPV) among US men who have sex with men (MSM). From 576 reviewed studies, a total of 28 met inclusion criteria and were included in the analysis. The population characteristics of each study, definitions of IPV, prevalences of different forms of IPV, and statistically tested correlates of IPV are summarized for each study. The results indicate that all forms of IPV occur among MSM at rates similar to or higher than those documented among women, although data on perpetration rates of IPV are scant, and consensus as to IPV correlates among MSM is absent. This review also finds significant limitations the reviewed literature, notably the lack of a standardized, validated definition of IPV among MSM; use of unspecific recall periods for IPV; a lack of attention to non-physical, non-sexual forms of IPV; and near-universal use of cross-sectional, convenience samples of urban MSM. Researchers should develop and validate a MSM-specific definition of IPV, use more rigorous epidemiological methods to measure IPV and its effects, and clarify the mental and physical health outcomes associated with both receipt and perpetration of IPV.

Intimate partner violence (IPV) affects an estimated 1.5 million U.S. women annually. IPV impacts maternal and neonatal health with higher rates of depression and low birth weight (LBW). Less studied is experiencing IPV and delivering a small for gestational age (SGA) baby. SGA neonates are at increased risk of developmental and behavioral problems. The negative sequelae persist into adulthood with increased rates of diabetes mellitus and coronary heart disease. In a sample of 239 pregnant women experiencing IPV, in urban and rural settings, we examined cross-sectional associations of severity of IPV and neonatal outcomes (i.e., birth weight and gestational age). Severity of IPV was measured by the Conflict Tactics Scale 2 and neonatal outcomes were collected at the time of delivery. Outcomes were collected on 194 neonates; 14.9% (n=29) were classified as LBW, 19.1% (n=37) classified as SGA, and 9.8% (n=19) as LBW and SGA. Women reporting higher severity of IPV during pregnancy had a greater likelihood of delivering an SGA neonate (odds ratio [OR] 4.81; 95% confidence interval [95% CI] 1.86-12.47), and LBW neonate (OR 4.20; 95% CI 1.46-12.10). In a sample of pregnant women experiencing perinatal IPV, women experiencing greater severities of IPV were more likely to deliver a neonate with an adverse outcome. Early recognition and intervention of IPV is essential to reduce disparities in birth outcomes and long-term health outcomes for these neonates.

Substance use and intimate partner violence victimization among White, African American, and Latina women.

2013-11-01

The existing literature on intimate partner violence (IPV) does not paint a consistent portrait of the impact of race/ethnicity. In addition, although research has clearly demonstrated that there is a relationship between substance use and IPV, the temporal ordering of these variables is not clearly established. This article seeks to examine the temporal ordering of IPV victimization and drug use using longitudinal data with a nationally representative racially and ethnically diverse sample. Data from Wave III (2001-2002) and Wave IV (2007-2008) of the National Longitudinal Study of Adolescent Health (Add Health) will serve as Time 1 and Time 2, respectively, to answer three research questions. First, does substance use during early young adulthood (Time 1) predict IPV victimization during young adulthood (Time 2) among women? Second, does IPV victimization during early young adulthood predict substance use during young adulthood for women? Finally, do these bidirectional relationships vary by race/ethnicity (i.e., White, African American, and Latina)? Four different forms of IPV (minor violence, major violence, rape/sexual coercion, and injury) are investigated along with binge drinking, marijuana use, and other drug use. Understanding not only the temporal relationship between substance use, trauma, and IPV but also the racial and ethnic differences in these relationships is critical to developing and refining culturally sensitive trauma-informed prevention and treatment services for women.

Economic Coercion and Partner Violence against Wives in Vietnam: A Unified Framework?

Economic coercion refers to behaviors that control an intimate partner’s ability to acquire, use, and maintain economic resources. Little is known about economic coercion in Vietnam. Using survey responses from 533 married women ages 18–50 years, we estimated multinomial logistic regression models to compare the determinants of exposure to economic coercion only, co-occurring economic coercion and any psychological, physical, or sexual intimate partner violence (IPV), and any IPV only, relative to no exposure. Women who, in their childhood, witnessed physical IPV against their mother had higher odds of exposure to co-occurring economic coercion and any IPV as an adult (aOR = 3.54, 95% CI 1.84–6.83) and any IPV only (aOR = 1.75, 95% CI 1.00–3.06), but not economic coercion only. Women who experienced violence as a child had higher odds of exposure to any IPV only (aOR =1.63, 95% CI 1.04–2.56) but not economic coercion only. Women with more schooling had higher odds of exposure to economic coercion only (aOR = 1.17, 95% CI 1.03–1.33) but not other forms of violence. Overall, the estimates from the three models differed significantly. Thus, the determinants of economic coercion and common forms of IPV may differ. More research should focus on men’s perpetration of economic coercion. PMID:25948643

The Association of Investment Model Variables and Dyadic Patterns of Physical Partner Violence: A Study of College Women.

Previous research has examined the association between intimate partner violence (IPV) victimization experiences and investment model variables, particularly with relation to leaving intentions. However, research only has begun to explore the impact that various dyadic patterns of IPV (i.e., unidirectional victimization, unidirectional perpetration, bidirectional violence, and non-violence) have on investment model variables. Grounded in behavioral principles, the current study used a sample of college women to assess the impact that perpetration and victimization have on investment model variables. Results indicated that 69.2% of the sample was in a relationship with no IPV. Among those who reported IPV in their relationships, 11.9% reported unidirectional perpetration, 10.6% bidirectional violence, and 7.4% unidirectional victimization. Overall, the findings suggest that women's victimization (i.e., victim only and bidirectional IPV) is associated with lower levels of satisfaction and commitment, and that women's perpetration (i.e., perpetration only and bidirectional IPV) is associated with higher levels of investment. Women in bidirectionally violent relationships reported higher quality alternatives than women in non-violent relationships. The current study emphasizes the importance of considering both IPV perpetration and IPV victimization experiences when exploring women's decisions to remain in relationships. © The Author(s) 2015.

The Relationship Between Internalized Homophobia and Intimate Partner Violence in Same-Sex Relationships: A Meta-Analysis.

2017-01-01

A meta-analysis was conducted to investigate the association between internalized homophobia and intimate partner violence (IPV) perpetration and victimization in same-sex relationships. The literature search and the application of the inclusion criteria made it possible to identify 10 studies, 2 of which were excluded due to missing data. Therefore, eight studies were finally included in the meta-analysis. The results showed positive and statistically significant associations between internalized homophobia and IPV perpetration and victimization, indicating that higher levels of internalized homophobia were related to higher levels of IPV. Specifically, the pooled effect size for the relationship between internalized homophobia and IPV perpetration (all forms), it was r + = .147, 95% confidence interval (CI) = [.079, .214]; for the association between internalized homophobia and physical/sexual IPV perpetration, it was r + = .166, 95% CI [.109, .221]; p < .0001; for the relationship between internalized homophobia and psychological IPV perpetration, it was r + = .145, 95% CI [.073, .216]; and for the association between internalized homophobia and any type of IPV victimization, it was r + = .102, 95% CI [.030, .173]. Implications of these results for clinical practice and future research are discussed.

Immigrants are vulnerable to Intimate partner violence (IPV). This study aims at characterising IPV among Colombian immigrants, and to identify its associated factors. Cross-sectional study on 336 Colombian immigrants (46 % women), aged 15-70 years, living in Spain. Self-reported questionnaire information on IPV suffered throughout the last year was collected face-to-face. Multivariable logistic regression was used to identify factors associated with IPV. Almost 30 % of participants reported IPV, without differences by gender (p = 0.339). Partner's alcohol consumption was associated with a higher frequency of being victim of IPV in both sexes. In women, low educational level, and discrimination were further associated to IPV. Younger age, and poorer self-perceived health in Spain as compared to Colombia were factors associated in men. Results showed similarly high levels of IPV among immigrant men and women. Alcohol consumption, education, discrimination, age, and poor self-perceived health were factors associated to IPV.

Understanding the Use of Violence Among Men Who Sustain Intimate Terrorism

Hines, Denise A.; Douglas, Emily M.

2011-01-01

Researchers in the field of intimate partner violence (IPV) are paying increasing levels of attention to the notion that members of aggressive and violent relationships cannot always be dichotomized as innocent victims versus blameworthy perpetrators; nonetheless, no research has documented characteristics of IPV victims that may predict their use of abusive and aggressive behaviors in response to their partners’ IPV. This study fills this gap and is unique because it uses a sample of 302 men who sustained intimate terrorism from their female partners and sought help. Results showed that victims who used physical IPV, in comparison with victims who did not, were younger and were more likely to abuse alcohol. In addition, in comparison with victims who used minor physical IPV, victims who used severe physical IPV were more likely to use—and use more frequently—other forms of IPV, and they were more likely to be substance abusers. Results are discussed in terms of possible theoretical implications, directions for future research, and practice implications. PMID:21841962

To explore the geographical distribution of mortality due to intimate partner violence (IPV) and reports of IPV according to the gender development index (GDI) of Spanish provinces. We performed an ecological study, based on GDI by provinces, of deaths from IPV and official complaints of IPV made by women between 1997 and 2004. The sources were the "Report on Human Capital and Human Development in Spain", the "Home Affairs Statistics Yearbook", and the web page of the Federation of Separated and Divorced Women. Provinces were divided into 2 groups according to whether their GDI score was above or below the mean GDI score for Spain (0.895). Mortality rates by age and rates of official complaints of IPV were calculated for the two groups of provinces (high and low GDI). Relative risks and their confidence intervals were calculated to analyze the risk of dying from or reporting IPV in low GDI provinces compared with that in high GDI provinces. The risk of death due to IPV was higher in women living in low GDI provinces than in those living in high GDI provinces (RR = 1.328; 95% CI, 1.253-1.406). Furthermore, the risk of reporting IPV was higher in low GDI provinces than in high GDI provinces (RR = 1.468; 95% CI, 1.462-1.474). Despite the trend to develop IPV strategies focused on individual causes, our results suggest that to tackle this problem, strategies for promoting gender equity in Spain are required.

Applying Differential Coercion and Social Support Theory to Intimate Partner Violence.

PubMed

Zavala, Egbert; Kurtz, Don L

2017-09-01

A review of the current body of literature on intimate partner violence (IPV) shows that the most common theories used to explain this public health issue are social learning theory, a general theory of crime, general strain theory, or a combination of these perspectives. Other criminological theories have received less empirical attention. Therefore, the purpose of this study is to apply Differential Coercion and Social Support (DCSS) theory to test its capability to explain IPV. Data collected from two public universities ( N = 492) shows that three out of four measures of coercion (i.e., physical abuse, emotional abuse, and anticipated strain) predicted IPV perpetration, whereas social support was not found to be significant. Only two social-psychological deficits (anger and self-control) were found to be positive and significant in predicting IPV. Results, as well as the study's limitations and suggestions for future research, are discussed.

Wadsworth, Pamela; Kothari, Catherine; Lubwama, Grace; Brown, Cathy L; Frank Benton, Jennifer

Intimate partner violence (IPV) predicts poor health for victims and their children, but little is known about the perspective of victims. This study reports the perspectives of adult female IPV victims about the impact of IPV on their health and barriers of health care access for themselves and their children. The majority rated their health as good to excellent (69%). However, 83.5% indicated that IPV negatively affected their health; 53.5% had unmet health care needs. Mental health care was the most common unmet need for women; children's unmet needs were immunizations and preventive care. Transportation difficulties posed the biggest barrier to health care access.

This article examines the cross-sectional association between acculturation, acculturation stress, drinking, and intimate partner violence (IPV) among Hispanic couples in the U.S. The data being analyzed come from a multicluster random household sample of couples interviewed as part of the second wave of a 5-year national longitudinal study. The overall survey response rate for the second wave is 72%. Participants are Hispanic couples 18 years of age or older (N = 387). Results show that, among men, lower acculturation is positively associated with higher acculturation stress, which is directly related to a greater likelihood of involvement in IPV. These associations are also present among women. However, data for women show an additional path linking higher levels of acculturation directly to IPV. Drinking is not associated with IPV, independent of gender. Acculturation, directly or through acculturation stress, increases the likelihood of IPV.

Associations of Intimate Partner Violence with Unintended Pregnancy and Pre-Pregnancy Contraceptive Use in South Asia

2015-01-01

Objective To assess associations of intimate partner violence (IPV) with pregnancy intendedness and pre-pregnancy contraceptive use among pregnant women in South Asia. Study Design Cross-sectional analyses were conducted using most recent Demographic and Health Surveys (DHS) from Bangladesh, India and Nepal for married, pregnant women aged 15–49 years who responded to IPV assessments specific to current marriage (N=4738). Adjusted logistic and multinomial regression analyses were conducted with pooled data to assess associations of IPV ever (sexual only, physical only, sexual plus physical, none) with the outcomes of pregnancy intendedness (wanted, mistimed or unwanted) and pre-pregnancy contraceptive use (no, traditional, or modern), for the current pregnancy. Results IPV was not associated with a mistimed or unwanted pregnancy. Sexual IPV was associated with pre-pregnancy modern contraceptive use (aOR=2.32, 95% CI=1.24, 4.36); sexual plus physical IPV was associated with pre-pregnancy traditional contraceptive use (aOR=1.85, 95% CI=1.12, 3.07). Post-hoc analysis of reasons for pre-pregnancy contraceptive discontinuation revealed that women with a history of IPV, particularly sexual IPV, had higher prevalence of contraceptive failure (sexual only: 37.3%, sexual plus physical: 30.9%, physical only: 22.6%, no IPV: 13.6%). Conclusion Pregnant women who experienced sexual IPV from husbands were more likely to use contraceptives pre-pregnancy but had no reduced risk unintended pregnancy, possibly due to higher rates of pre-pregnancy contraceptive failure among those with this history. These findings suggest that victims of sexual IPV are able to acquire and use family planning services, but require more support to sustain effective contraceptive use. Implications Family planning services are reaching women affected by sexual IPV, and programs should be sensitive to this concern and the heightened vulnerability to contraceptive failure these women face. Long-acting reversible contraception could be beneficial by allowing women to have greater reproductive control in situations of compromised sexual autonomy. PMID:25769441

To assess associations of intimate partner violence (IPV) with pregnancy intendedness and pre-pregnancy contraceptive use among pregnant women in South Asia. Cross-sectional analyses were conducted using the most recent Demographic and Health Surveys from Bangladesh, India and Nepal for married, pregnant women aged 15-49 years who responded to IPV assessments specific to current marriage (N=4738). Adjusted logistic and multinomial regression analyses were conducted with pooled data to assess associations of IPV ever (sexual only, physical only, sexual plus physical or none) with the outcomes of pregnancy intendedness (wanted, mistimed or unwanted) and pre-pregnancy contraceptive use (no, traditional or modern) for the current pregnancy. IPV was not associated with a mistimed or unwanted pregnancy. Sexual IPV was associated with pre-pregnancy modern contraceptive use (aOR=2.32, 95% CI=1.24, 4.36); sexual plus physical IPV was associated with pre-pregnancy traditional contraceptive use (aOR=1.85, 95% CI=1.12, 3.07). Post hoc analysis of reasons for pre-pregnancy contraceptive discontinuation revealed that women with a history of IPV, particularly sexual IPV, had higher prevalence of contraceptive failure (sexual only, 37.3%; sexual plus physical, 30.9%; physical only, 22.6%; no IPV, 13.6%). Pregnant women who experienced sexual IPV from husbands were more likely to use contraceptives pre-pregnancy but had no reduced risk unintended pregnancy, possibly due to higher rates of pre-pregnancy contraceptive failure among those with this history. These findings suggest that victims of sexual IPV are able to acquire and use family planning services but require more support to sustain effective contraceptive use. Family planning services are reaching women affected by sexual IPV, and programs should be sensitive to this concern and the heightened vulnerability to contraceptive failure these women face. Long-acting reversible contraception could be beneficial by allowing women to have greater reproductive control in situations of compromised sexual autonomy. Copyright © 2015 Elsevier Inc.

Despite World Health Organization guidelines on health service responses to intimate partner violence (IPV) against women general practitioners (GPs) often overlook the problem. Training on IPV addresses GPs' barriers to asking women patients about abuse and responding appropriately. One of the barriers is stereotype of women as passive victims. Little is known about coping behaviour of women patients with a history of IPV. The objectives are (i) to compare problem- and emotion-focused coping used by patients who have experienced IPV with those who have not; (ii) to examine whether greater coping resources (health, education, employment and income) would be associated with more problem-focused coping. The Russian Ways of Coping Questionnaire was administered to every fifth woman who participated in a cross-sectional survey on IPV prevalence in 24 St Petersburg general practices. Linear regression was used (n = 159) to test associations between life-time IPV, coping resources and ways of coping. Mean problem-focused coping scores were 0.2-4.7 units higher in those patients who have experienced IPV compared with those who have not [95% confidence interval (CI): -4.2, 11.9; P = 0.16-0.92], while mean emotion-focused coping scores were 2.5-4.2 units higher (95% CI: -3.0, 11.0; P = 0.12-0.57). After adjustment for coping resources there was no evidence for an association between IPV and problem-focused coping. Patients who have experienced IPV use as much problem-focused and emotion-focused coping, as those patients who have not experienced IPV. These findings should be incorporated into training on IPV to address GPs' stereotypes towards patients who have experienced IPV. © The Author 2015. Published by Oxford University Press.

Desistance from intimate partner violence: the role of legal cynicism, collective efficacy, and social disorganization in Chicago neighborhoods.

PubMed

Emery, Clifton R; Jolley, Jennifer M; Wu, Shali

2011-12-01

This paper examined the relationship between reported Intimate Partner Violence (IPV) desistance and neighborhood concentrated disadvantage, ethnic heterogeneity, residential instability, collective efficacy and legal cynicism. Data from the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal survey were used to identify 599 cases of IPV in Wave 1 eligible for reported desistance in Wave 2. A Generalized Boosting Model was used to determine the best proximal predictors of IPV desistance from the longitudinal data. Controlling for these predictors, logistic regression of neighborhood characteristics from the PHDCN community survey was used to predict reported IPV desistance in Wave 2. The paper finds that participants living in neighborhoods high in legal cynicism have lower odds of reporting IPV desistance, controlling for other variables in the logistic regression model. Analyses did not find that IPV desistance was related to neighborhood concentrated disadvantage, ethnic heterogeneity, residential instability and collective efficacy.

Predicting Adolescent Dating Violence Perpetration: Role of Exposure to Intimate Partner Violence and Parenting Practices.

2015-09-01

Exposure to adult intimate partner violence (IPV) places youth at risk for a range of outcomes, including perpetration of adolescent dating violence (ADV). However, there is variability in the effect of IPV exposure, as many youth who are exposed to IPV do not go on to exhibit problems. Thus, research is needed to examine contextual factors, such as parenting practices, to more fully explain heterogeneity in outcomes and better predict ADV perpetration. The current research draws from a multisite study to investigate the predictive power of IPV exposure and parenting practices on subsequent ADV perpetration. Participants included 417 adolescents (48.7% female) drawn from middle schools in high-risk, urban communities. IPV exposure, two types of parenting practices (positive parenting/involvement and parental knowledge of their child's dating), and five types of ADV perpetration (threatening behaviors, verbal/emotional abuse, relational abuse, physical abuse, and sexual abuse) were assessed at baseline (2012) and approximately 5 months later (2013) via adolescent report. Analyses (conducted in 2015) used a structural equation modeling approach. Structural models indicated that IPV exposure was positively related only to relational abuse at follow-up. Further, adolescents who reported parents having less knowledge of dating partners were more likely to report perpetrating two types of ADV (physical and verbal/emotional abuse) at follow-up. Analyses did not demonstrate any significant interaction effects. Results fill a critical gap in understanding of important targets to prevent ADV in middle school and highlight the important role that parents may play in ADV prevention. Published by Elsevier Inc.

The associations between sex, immigrant status, immigrant concentration and intimate partner violence: evidence from the Canadian General Social Survey.

Intimate partner violence (IPV) is an important public health concern, yet little is known about the combined effects of individual- and neighbourhood-level characteristics on IPV among immigrants. The aim of this study is to examine: (1) the association between immigrant status and IPV victimisation and whether sex modifies this association, and (2) the association between the neighbourhood concentration of immigrants and IPV victimisation, and whether immigrant status modifies this association. Our sample of 10,964 males and females comes from the 2009 Canadian General Social Survey. After controlling for covariates, immigrant status was not associated with IPV, and sex significantly modified the association between immigrant status and financial and physical/sexual IPV. Compared to males, second-generation females were less likely to report financial IPV and first-generation females were more likely to report physical/sexual IPV. Immigrant status modified the association between the neighbourhood concentration of immigrants and emotional and physical/sexual IPV. Compared to third-generation males, first-generation males living in neighbourhoods with a higher concentration of immigrants were more likely to report emotional IPV, whereas second-generation males in these neighbourhoods were less likely to report physical/sexual IPV. Interventions to reduce IPV should pay equal attention to individual- and neighbourhood-level influences.

Purpose We assess the association of men's exposure to violence in childhood--witnessing physical violence against one’s mother and being hit or beaten by a parent or adult relative--with their attitudes about intimate partner violence (IPV) against women. We explore whether men’s perpetration of IPV mediates this relationship and whether men’s attitudes about IPV mediate any relationship of exposure to violence in childhood with perpetration of IPV. Methods 522 married men 18–51 years in Vietnam were interviewed. Multivariate regressions for ordinal and binary responses were estimated to assess these relationships. Results Compared to men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of reporting more reasons to hit a wife (aORs, 95%CIs: 1.43, 1.03–2.00 and 1.66, 1.05–2.64, respectively). Men’s lifetime perpetration of IPV accounted fully for these associations. Compared to men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of ever perpetrating IPV (aORs, 95%CIs: 3.28, 2.15–4.99 and 4.56, 2.90–7.17, respectively). Attitudes about IPV modestly attenuated these associations. Conclusion Addressing violence in childhood is needed to change men’s risk of perpetrating IPV and greater subsequent justification of it.

We assess the association of men's exposure to violence in childhood-witnessing physical violence against one's mother and being hit or beaten by a parent or adult relative-with their attitudes about intimate partner violence (IPV) against women. We explore whether men's perpetration of IPV mediates this relationship and whether men's attitudes about IPV mediate any relationship of exposure to violence in childhood with perpetration of IPV. Five hundred twenty-two married men 18-51 years in Vietnam were interviewed. Multivariate regressions for ordinal and binary responses were estimated to assess these relationships. Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of reporting more reasons to hit a wife (aOR, 1.43; 95% CI, 1.03-2.00 and aOR, 1.66; 95% CI, 1.05-2.64, respectively). Men's lifetime perpetration of IPV accounted fully for these associations. Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of ever perpetrating IPV (aOR, 3.28; 95% CI, 2.15-4.99 and aOR, 4.56; 95% CI, 2.90-7.17, respectively). Attitudes about IPV modestly attenuated these associations. Addressing violence in childhood is needed to change men's risk of perpetrating IPV and greater subsequent justification of it.

While intimate partner violence (IPV) is a global concern for women's health, there are few comparative studies of IPV training in medical schools. The aim of this study was to investigate medical students' knowledge of, and training in, IPV in the USA, Vietnam and China. Cross-national, cross-sectional study. US (n = 60), Vietnamese (n = 232) and Chinese (n = 174) medical students participated in a cross-sectional self-administered survey that included demographic characteristics; opinions, training and knowledge regarding IPV against women; and personal experience with IPV victims. Attitudes, knowledge and training about IPV among medical students varied between the three countries. US participants reported higher levels of knowledge of IPV, were more likely to believe that IPV was a serious problem, and were more likely to consider IPV to be a healthcare problem compared with Vietnamese and Chinese participants. Chinese participants, in particular, did not appear to appreciate the importance of addressing IPV. Differences were found between the Vietnamese and Chinese students. While most medical schools in the USA include IPV training within their core medical curricula, education throughout medical school seems to be necessary to improve medical education regarding treatment of patients with a history of IPV. Vietnamese and Chinese medical schools should consider including IPV education in the training of their future physicians to improve the health of women who have experienced IPV. Practical opportunities for medical students to interact with women who have experienced IPV are essential to develop effective IPV education. Copyright © 2015 The Royal Society for Public Health.

Intimate partner violence (IPV) research among men who have sex with men (MSM) has primarily focused on the prevalence of IPV victimization and perpetration. Although alcohol use is a known trigger of IPV in opposite sex relationships, less is known about alcohol use and IPV perpetration and victimization in same-sex couples. The aim of this study was to examine associations between alcohol use and different types of IPV victimization and perpetration among MSM. MSM in New York City were recruited at gay-friendly venues and events to participate in an online survey assessing sociodemographics, alcohol use, and victimization/perpetration of IPV with both regular and casual sex partners. Logistic regression was used to examine associations between alcohol use and different types of IPV victimization and perpetration. Among 189 participants, 103 (54.5%) reported experiencing at least one incidence of IPV perpetrated by a regular partner and 92 (48.7%) reported having perpetrated IPV against a regular partner in the past 12 months. Higher levels of alcohol use were significantly associated with (1) physical/sexual and HIV-related IPV victimization by a regular partner, (2) physical/sexual, monitoring, and controlling IPV victimization by a casual partner, (3) physical/sexual, emotional, controlling, and HIV-related IPV perpetration against a regular partner, and (4) physical/sexual and emotional IPV perpetration against a casual partner. The association of high levels of alcohol use with different types of IPV perpetration and IPV victimization suggests a need for targeted services that address the co-occurring issues of alcohol use and IPV.

Controlling behaviours are highly prevalent forms of non-physical intimate partner violence (IPV). The prevalence of perpetrating controlling behaviours and technology-facilitated abuse (TFA) was compared by men receiving substance use treatment in England (n = 223) and Brazil (n = 280). Factors associated with perpetrating these behaviours towards their current/most recent partner and their association with other types of IPV were explored. Secondary analysis from two cross-sectional studies was performed. Data on socio-demographic characteristics, infidelity, IPV perpetration and victimisation, adverse childhood experiences (ACE), attitudes towards gender relations and roles, substance use, depressive symptoms and anger expression were collected. Sixty-four percent (143/223) and 33% (73/223) of participants in England and 65% (184/280) and 20% (57/280) in Brazil reported controlling behaviours and TFA, respectively, during their current/most recent relationship. Excluding IPV victimisation from the multivariate models; perpetrating controlling behaviours was associated with a higher number of ACE, higher anger expression (England) and severe physical IPV perpetration (Brazil), and perpetrating TFA was associated with younger age. Including both IPV victimisation and perpetration in the multivariate models; perpetrating controlling behaviour was associated with experiencing a higher number of ACE, higher anger expression (England), emotional IPV victimisation (England) and experiencing controlling behaviour from a partner (England). The perpetration of TFA was associated with younger age and experiencing TFA from a partner. Technological progress provides opportunities for perpetrators to control and abuse their partners. Controlling behaviours and TFA should be addressed to reduce IPV perpetration by males in substance use treatment. [Gilchrist G, Canfield M,Radcliffe P, d'Oliveira AFPL.

Intimate Partner Violence (IPV) is a global public health problem. IPV prevalence in Indonesia has been estimated to be less than 1%, based on reported cases. It is likely that IPV prevalence is underreported in Indonesia, as it is in many other countries. Screening for IPV has been found to increase IPV identification, but no screening tools are in use in Indonesia. The aim of this study was to test the translated Woman Abuse Screening Tool (WAST) for detecting IPV in Indonesia. The WAST was tested against a diagnostic interview by a trained psychologist on 240 women attending two Primary Health Centers in Jakarta. IPV prevalence and the reliability, sensitivity, and specificity of the WAST were estimated. Prevalence of IPV by diagnostic interview was 36.3%, much higher than published estimates. The most common forms of IPV identified were psychological (85%) and physical abuse (24%). Internal reliability of the WAST was high (α = .801). A WAST score of 13 (out of 24) is the recommended cutoff for identifying IPV, but only 17% of the Indonesian sample scored 13 or higher. Test sensitivity of the WAST with a cutoff score of 13 was only 41.9%, with a specificity of 96.8%. With a cutoff score of 10, the sensitivity improved to 84.9%, while the specificity decreased to 61.0%. Use of the WAST with a cutoff score of 10 provides good sensitivity and reasonable specificity and would provide a much-needed screening tool for use in Indonesia. Although a lower cutoff would yield a greater proportion of false positives, most of the true cases would be identified, increasing the possibility that women experiencing abuse would receive needed assistance. © The Author(s) 2014.

Women who inject drugs are disproportionately affected by HIV and intimate partner violence (IPV); however, the link between IPV and HIV remains under-researched among substance-using women in low- and middle-income countries. This study examined associations and additive effects of different forms of IPV victimization (psychological, physical and/or injurious, and sexual) on HIV sexual risk behavior among women who inject drugs in Indonesia. Respondent-driven sampling (RDS) was used to recruit 731 women from Greater Jakarta and Bandung, West Java. RDS-II weighted prevalence of any past-year IPV was 68.9% (95% CI 65.0, 72.6) in Jakarta and 55.9% (95% CI 48.0, 63.5) in Bandung. In separate logistic regressions controlling for socio-demographic covariates, all three forms of IPV showed statistically significant associations with sexual risk behavior. After adjusting for all IPV types, psychological (OR 1.87; 95% CI 1.17, 2.99; p = 0.009) and sexual (OR 1.98; 95% CI 1.22, 3.21; p = 0.006) IPV independently predicted women's sexual risk behavior. Marginal effects models suggested that co-occurrence of multiple forms of IPV had greater adverse consequences: sexual risk behavior was reported by 64.1% of women who did not experience any IPV, but increased to 89.9% among women exposed to all three types. Comprehensive harm reduction services that integrate IPV monitoring and prevention are urgently needed to reduce both HIV and IPV.

Community matters: intimate partner violence among rural young adults.

Drawing on social disorganization theory, the current study examined the extent to which community-level poverty rates and collective efficacy influenced individual reports of intimate partner violence (IPV) perpetration, victimization, and bystander intervention among a sample of 178 young adults (18-24; 67.4% women) from 16 rural counties across the eastern US who completed an online survey that assessed demographic information, IPV perpetration, victimization, bystander intervention, and collective efficacy. We computed each county's poverty rate from the 2007-2011 American Community Survey. Generalized estimating equations demonstrated that after controlling for individual-level income status, community-level poverty positively predicted IPV victimization and perpetration for both men and women. Collective efficacy was inversely related to IPV victimization and perpetration for men; however, collective efficacy was unrelated to IPV victimization and perpetration for women. Whereas IPV bystander intervention was positively related to collective efficacy and inversely related to individual-level income status for both men and women, community-level poverty was unrelated to IPV bystander intervention for both men and women. Overall, these findings provide some support for social disorganization theory in explaining IPV among rural young adults, and underscore the importance of multi-level IPV prevention and intervention efforts focused around community-capacity building and enhancement of collective efficacy.

Social support and employment status modify the effect of intimate partner violence on depression symptom severity in women: results from the 2006 Behavioral Risk Factor Surveillance System Survey.

Depression and intimate partner violence (IPV) are significant health issues for U.S. women. Interaction effects between IPV and other psychosocial factors on the severity of depressive symptoms have not been fully explored. This study assessed effect modification, that is, how IPV interacts with sociodemographics, psychosocial factors and health risk behaviors, on the severity of depressive symptoms in women. We utilized cross-sectional data from female respondents (n = 16,106) of the 2006 Behavioral Risk Factors Surveillance Survey. Sociodemographics, psychosocial variables, and health risk behaviors determined to be significantly associated with depression were tested for interaction effects with IPV. Weighted ordinal logistic regression and predicted probabilities illustrated the effect of IPV status on depressive symptom severity, stratified by interaction effects. Recent and lifetime IPV exposure were associated with more severe depressive symptoms compared with no IPV exposure. IPV history interacted with employment status and social support on the severity of depressive symptoms in women. Overall, any IPV exposure was associated with more severe depressive symptoms among women with low social support and unemployment, although the effect of recent (versus lifetime) IPV was most pronounced among women with high social support or employed women. Social support and employment status interact with IPV on the severity of depressive symptoms in women. Therefore, social support or workplace interventions designed to improve depressive symptoms should examine IPV history. Copyright © 2014 Jacobs Institute of Women's Health.

To assess the prevalence of intimate partner violence (IPV) in a sample of Ukrainian mothers of schoolchildren, and to examine the relationship between IPV and family, parent, and child characteristics utilizing multilevel models. Mothers of children aged 9-16 (n = 278, 93.5% Ukrainians) answered the Revised Conflict Tactics Scale (CTS2) assessing IPV. We also examined the relationship between IPV and maternal age, education, employment and marital status, family income, and rural or urban residence. Eighty-one percent of women reported psychological violence and 58% reported physical assault. On average, women reported 66 instances of IPV during the last year. Multilevel modeling revealed that lower maternal education, unemployment, not living with the husband or partner, and urban residency were associated with higher IPV victimization. Younger age and family income were not significantly related to IPV. IPV was a significant social problem in the present sample of Ukrainian mothers of school age children. Future policy and violence prevention programming should focus on supporting academic and employment opportunities for women, particularly for those living in urban areas.

An examination of domestic partner violence and its justification in the Republic of Georgia

Background Little research on Intimate Partner Violence (IPV) and social perceptions toward this behavior has been disseminated from Eastern Europe. This study explores the prevalence and risk factors of IPV and the justification of this behavior among women in the Republic of Georgia. It seeks to better understand how IPV and IPV justification relate and how social justification of IPV differs across socio-economic measures among this population of women. Methods This study utilizes a national sample of ever-married women from the Republic of Georgia (N = 4,302). We describe the factors that predict IPV justification among these women and the relationship between of the acceptability of IPV and victimization overall and across socio-demographic factors. Results While the overall lifetime prevalence of IPV in this sample was relatively low (4%), these women were two to four times more likely to justify IPV, Just under one-quarter of the sample agreed that IPV was justified in at least one scenario, namely when the wife was unfaithful, compared with women who had no experience being abused by a partner. Georgian women who were poor, from a rural community, had lower education, were not working and who experienced child abuse or IPV among their parents were more likely to justify this behavior. Conclusions These findings begin to fill a gap in our understanding of IPV experienced by women in Eastern Europe. In addition, these findings emphasize the need for researchers, practitioners and policy makers to contextualize IPV in terms of the justification of this behavior among the population being considered as this can play an important role in perpetration, victimization and response.

The Development of Attitudes Toward Intimate Partner Violence: An Examination of Key Correlates Among a Sample of Young Adults

Social learning theory remains one of the leading explanations of intimate partner violence (IPV). Research on attitudes toward IPV represents a logical extension of the social learning tradition, as it is intuitive to expect that individuals exposed to violence in the family of origin may internalize behavioral scripts for violence and adopt attitudes accepting of IPV. Yet despite this assumed link between family violence and attitudes toward IPV, few studies have empirically examined factors associated with the development of such attitudes. Using data from the Toledo Adolescent Relationship Study (TARS), we examine the role of family violence on the adoption of attitudes accepting of IPV among a sample of young adults (n = 928). The current investigation contributes to existing literature on attitudes toward IPV by (a) providing an empirical examination of factors associated with attitudes toward IPV in predictive models; (b) relying on a multifaceted index, describing specific conditions under which IPV may be deemed justifiable; (c) examining extra-familial factors, in addition to family violence exposure, to provide a more comprehensive account of factors associated with attitudes toward IPV; and (d) focusing particular attention on the role of gender, including whether the factors associated with attitudinal acceptance of IPV are similar for men and women. Findings indicated considerable variation in overall endorsement of attitudes regarding the use of violence across conditions, with greater endorsement among women. Consistent with social learning approaches to IPV, exposure to violence in the family of origin was associated with attitudes toward IPV. Yet findings also signaled the salience of factors beyond the family, including a range of sociodemographic, relationship, and adult status characteristics. We discuss the relevance of our findings for future theorizing and research in the area of attitudes toward IPV. PMID:27229921

Constrained relationship agency as the risk factor for intimate partner violence in different models of transactional sex

Women who engage in transactional sex are more likely to experience intimate partner violence (IPV) and are at higher risk of HIV. However, women engage in transactional sex for a variety of reasons and the precise mechanism linking transactional sex and IPV is not fully understood. We conducted a behavioural survey with a cross-sectional sample of 401 women attending 1 rural and 1 urban public antenatal clinic in Swaziland between February and June 2014. We used structural equation modelling to identify and measure constrained relationship agency (CRA) as a latent variable, and then tested the hypothesis that CRA plays a significant role in the pathway between IPV and transactional sex. After controlling for CRA, receiving more material goods from a sexual partner was not associated with higher levels of physical or sexual IPV and was protective against emotional IPV. CRA was the single largest predictor of IPV, and more education was associated with decreased levels of constrained relationship agency. Policies and interventions that target transactional sex as a driver of IPV and HIV may be more successful if they instead target the broader social landscape that constrains women’s agency and drives the harmful aspects of transactional sex.

The purpose of this study was to assess via longitudinal analysis whether women's economic empowerment and financial inclusion predicts incident IPV. This prospective study involved analysis of three waves of survey data collected from rural young married women (n = 853 women) in Maharashtra at baseline and 9&18 month follow-ups. This study, which was in the field from 2012 to 2014, was conducted as part of a larger family planning evaluation study unrelated to economic empowerment. Participants were surveyed on economic empowerment, as measured by items on women's income generation and joint decision-making of husband's income, and financial inclusion, as measured by bank account ownership. Women's land ownership and participation in microloan programs were also assessed but were too rare (2-3% reporting) to be included in analyses. Longitudinal regression models assessed whether women's economic empowerment predicted incident IPV at follow-up. At Wave 1 (baseline), one in ten women reported IPV in the past six months; 23% reported income generation; 58% reported having their own money; 61% reported joint control over husband's money, and 10% reported bank ownership. Women's income generation and having their own money did not predict IPV over time. However, women maintaining joint control over their husband's income were at a 60% reduced risk for subsequent incident IPV (AOR = 0.40; 95% CI = 0.18, 0.90), and women gaining joint control over time were at a 70% reduced risk for subsequent incident IPV (AOR = 0.30; 95% CI = 0.13, 0.72), relative to women whose husbands maintained sole control over his income. Women who initiated a new bank account by Wave 3 also had a 56% reduced likelihood of reporting incident IPV in this same wave (AOR = 0.44; 95% CI = 0.22, 0.93), relative to those who maintained no bank account at Waves 1 and 3. These findings suggest that women's joint control over husband's income and her financial inclusion as indicated by bank ownership appear to reduce risk for IPV, whereas her income generation or control over her own income do not. Awareness of and participation in financial inclusion services may help reduce women's risk for IPV in rural India and elsewhere. Copyright © 2017. Published by Elsevier Ltd.

Religion, Religious Heterogeneity, and Intimate Partner Violence Among Korean Immigrant Women.

Kim, Chunrye

2018-02-01

This study examined the role of religious affiliations and frequency of religious service attendance-such as church, Bible studies, and temples-as well as religious heterogeneity between couples on intimate partner violence (IPV) among Korean immigrant women in the United States. Through a case-control design, this study compared 64 Korean immigrant IPV victims with 63 Korean immigrant non-IPV victims. This study's findings reveal that for Korean immigrant women, a high frequency of religious service attendance was associated with higher IPV victimization, while their partners' high religious service attendance was associated with lower IPV victimization. When women's partners were religious compared with when they were not religious, they were less likely to perpetrate IPV even when the partners' alcohol consumption frequency increased. Also, when there was a gap between couples regarding frequency of religious attendance, IPV victimization increased. This discussion concludes by suggesting some policy implications based on these findings.

GMP-batches of Sabin-IPV were characterized for their antigenic and immunogenic properties. Antigenic fingerprints of Sabin-IPV reveal that the D-antigen unit is not a fixed amount of antigen but depends on antibody and assay type. Instead of the D-antigen unit we propose standardization of IPV based on a combination of protein amount for dose and D-antigenicity for quality of the vaccine. Although Sabin-IPV type 2 is less immunogenic than regular wild type IPV type 2, the immunogenicity (virus neutralizing titers) per microgram antigen for Sabin-IPV type 2 is in the same order as for wild type serotypes 1 and 3. The latter observations are in line with data from human trials. This suggests that a higher dose of Sabin-IPV type 2 to compensate for the lower rat immunogenicity may not be necessary.

Dardis, Christina M; Shipherd, Jillian C; Iverson, Katherine M

2017-08-01

National estimates suggest intimate partner violence (IPV) rates are equal or higher among lesbian, bisexual, or questioning (LBQ)-identified women than heterosexual-identified women. Women veterans are a population at high risk for IPV, yet the occurrence of lifetime and past-year IPV experiences by sexual orientation have not been examined in this population. Lifetime and past-year IPV experiences and current IPV-related posttraumatic stress disorder (PTSD) symptoms were assessed with validated screening measures as part of a 2014 web-based national survey of women veterans. Among 403 respondents, 9.7% (n = 39) identified as LBQ, and 90.3% (n = 364) identified as heterosexual. When controlling for age, LBQ-identified women veterans were significantly more likely to report lifetime sexual and physical IPV and lifetime intimate partner stalking. In the past year, LBQ-identified veterans were twice as likely to endorse emotional mistreatment and physical IPV, and three times more likely to endorse sexual IPV, than were heterosexual-identified women veterans. However, sexual orientation was unrelated to IPV-related PTSD symptoms, when controlling for age, race, and number IPV forms experienced. IPV is prevalent among LBQ-identified women veterans, suggesting the need to understand the potentially unique contextual factors and health-care needs of this group.

To describe the prevalence of intimate partner violence (IPV) in Spain in the last year and at some point during the lifetime, to determine health status in women according to whether they had experienced IPV or not, and to analyze the individual variables associated with IPV in Spain. A cross-sectional study was performed of the database, Macrosurvey on Gender Violence in Spain 2011. This database includes data on 7,898 women older than 18 years old. The dependent variables were IPV-last year, IPV-ever in life. Covariates consisted of sociodemographic characteristics, socioeconomic status, maternal experience of IPV, social support, and self-care. The measure of association used was the OR with its 95% confidence interval (95% CI). A total of 3.6% of women had experienced IPV-last year and 12.2% ever in life. Female victims of IPV had poorer health than women who had not experienced IPV. Immigrant women living in Spain for 6 years or more were more likely to experience IPV-ever in life than Spanish women [OR (95% CI): 1.95 (1.50, 2.53)]. An interaction was found between nationality and the existence of children under 18 years old. Among women with children under 18 years old, immigrant women were more likely to experience IPV-last year than Spanish women [OR (95% CI): 1.99 (1.25, 3.17)]. Other variables associated with IPV were age, low socioeconomic status, low social support and having a mother who had experienced IPV. In Spain, some women have a higher probability of experiencing IPV. The variables associated with greater vulnerability to IPV should be taken into account when implementing measures to prevent or alleviate IPV. Copyright © 2013 SESPAS. Published by Elsevier Espana.

Empowerment, PTSD and revictimization among women who have experienced intimate partner violence.

PubMed

Dardis, Christina M; Dichter, Melissa E; Iverson, Katherine M

2018-08-01

Empowerment is associated with lower posttraumatic stress disorder (PTSD) symptoms and intimate partner violence (IPV) revictimization, but the direction of these associations remains unknown. Two models were assessed: one in which empowerment is protective against future IPV revictimization and PTSD symptoms, and one in which PTSD symptoms lead to reductions in empowerment and increases in IPV revictimization. Drawn from a probability-based access survey panel of U.S. adults, the present sample included 101 women veterans who experienced past-year IPV. Baseline demographics were assessed (T0), with surveys conducted at Time 1 (T1; 18-month interim), and Time 2 (T2; 6-month interim). Cross-lagged panel models assessed the two models separately among women who reported only T1 psychological IPV victimization (58%) and women who reported T1 physical and/or sexual IPV victimization. Among psychological IPV victims, T1 empowerment was significantly associated with decreased T2 PTSD symptoms, whereas among women who reported physical and/or sexual IPV victimization, T1 empowerment was significantly associated with decreased T2 IPV revictimization. The model in which PTSD symptoms confer risk for lower empowerment was not supported; however, higher T1 PTSD symptoms were associated with increased IPV revictimization among women who reported psychological IPV only. Findings can inform interventions for IPV survivors. Copyright © 2018 Elsevier B.V. All rights reserved.

A cycle of violence? Examining family-of-origin violence, attitudes, and intimate partner violence perpetration.

Eriksson, Li; Mazerolle, Paul

2015-03-01

Exposure to violence in the family-of-origin has consistently been linked to intimate partner violence (IPV) perpetration in adulthood. However, whether the transmission of violence across generations is role- and gender-specific still remains unclear. The current study examined the effects of experiencing child abuse and observing parental violence on IPV perpetration among a sample of male arrestees (N = 303). The differential effects of observing violence perpetrated by same-sex (father to mother), opposite-sex (mother to father), and both parents on subsequent IPV perpetration were examined. Logistic regression analyses showed that while observing father-only violence and bidirectional interparental violence was predictive of IPV perpetration, observing mother-only violence and direct experiences of child abuse was not. These findings suggest that the transmission of violence across generations is both role- and gender-specific and highlight the importance of examining unique dimensions of partner violence to assess influences on children. The study further examined whether attitudes justifying wife beating mediate the effect of exposure to violence and subsequent IPV perpetration. Results showed that although attitudes were predictive of perpetration, these attitudes did not mediate the relationship. © The Author(s) 2014.

Interpersonal violence (IPV) is associated with a range of subsequent negative outcomes; however, research has yet to test whether IPV operates as a specific risk factor for separate psychopathology outcomes, such as posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, delinquent acts, or binge drinking. To address this, cumulative exposure to IPV and non-IPV-related traumatic events, PTSD symptoms, depressive symptoms, delinquent acts, and binge drinking were measured 3 times over approximately 3 years among a nationally representative sample of adolescents aged 12-17 (N = 3,614 at Wave 1). Results demonstrated that cumulative IPV exposure predicted subsequent PTSD, depression, delinquency, and binge drinking (βs = .07, .12, .10, and .09, respectively; all ps < .01) when all cross-relationships (e.g., the effect of delinquency on future binge drinking) were in the model. Exposure to non-IPV traumatic events generally did not confer vulnerability to subsequent psychopathology outcomes. Overall, findings from this study advance the literature in this area by exploring consequences for adolescents following cumulative IPV exposure.

Siblings exposed to intimate partner violence: linking sibling relationship quality & child adjustment problems.

Piotrowski, Caroline C; Tailor, Ketan; Cormier, Damien C

2014-01-01

Although the majority of families that experience intimate partner violence (IPV) have more than one child, most research to date has focused upon a single child within these families. A significant body of research has indicated siblings play an important role in children's adjustment and well-being. To address this gap, the three main goals of the present study were to compare the adjustment of older and younger siblings exposed to IPV, to describe and compare the quality of these sibling relationships from multiple perspectives, and to investigate how sibling adjustment and relationship quality influence children's adjustment. Forty-seven sibling pairs and their mothers were recruited from the community. Mothers self-reported on their violent experiences using the Conflict Tactics Scale, and also estimated the length of time their children were exposed to IPV. Mothers and children completed assessments of child adjustment and the quality of sibling relationships. Observers also assessed the quality of sibling interaction. Results indicated that adjustment between siblings was highly inter-related. On average, mothers reported sibling relationships as less positive but also as less hostile than did siblings themselves. Higher levels of sibling hostility, lower levels of sibling warmth and higher levels of disengagement each significantly predicted child adjustment; however, these effects were predicated upon the adjustment of the other sibling. The sibling relationships of children exposed to IPV made a difference in their individual adjustment, and their adjustment issues influenced how they feel about and interacted with their sibling. Sibling hostility played a stronger role in adjustment issues than sibling warmth. The nature of sibling influences and the direction of future research were discussed. Copyright © 2013 Elsevier Ltd.

Intimate partner violence and its implication for pregnancy.

PubMed

Chambliss, Linda R

2008-06-01

Intimate partner violence (IPV) is a common occurrence in pregnancy and results in an increased risk of adverse outcomes. Homicide may be the most common cause of maternal death. Women who are pregnant and the victims of IPV have high rates of stress, are more likely to smoke or use other drugs, deliver a preterm or low birth weight infant, have an increase in infectious complications, and are less likely to obtain prenatal care. The IPV continues in the postpartum period. Adolescents may be at even higher risk than their adult counterparts. Children raised in violent homes have both immediate and life long adverse health outcomes as a result of their exposure to IPV. IPV adds substantially to healthcare costs both for direct services to treat the injuries and higher utilization of a wide range of healthcare services. Healthcare providers, particularly those who care for pregnant women, are in a unique position to identify these women and direct them and their families to the help they need to end the violence in their lives.

Childhood Social Functioning and Young Adult Intimate Partner Violence in Girls With and Without ADHD: Response Inhibition as a Moderator.

Youn, Cherry; Meza, Jocelyn I; Hinshaw, Stephen P

2018-06-01

Examine the moderating effects of response inhibition on the longitudinal association between social preference/relational aggression measured in childhood, and intimate partner violence (IPV) measured in young adulthood, among women with ( n = 140) and without ( n = 88) histories of childhood ADHD. During childhood, social preference was measured through confidential peer sociometric nominations, yielding negative and positive peer regard; relational aggression was assessed via staff behavioral observations; and response inhibition was assessed using commission errors from the continuous performance task. During young adulthood, IPV was ascertained via a clinician-administered, semistructured interview. Social preference and relational aggression independently predicted IPV; this prospective link was moderated by response inhibition. In combination with low social preference or high relational aggression in childhood, poor response inhibition predicted the highest levels of young-adult IPV. Given the developmental significance of peer relationships, additional research on the causes of and treatments for poor social functioning in ADHD is warranted.

Intimate partner violence (IPV) is a global health issue affecting mainly women and is known to escalate during pregnancy and impact negatively on obstetric and perinatal outcomes. The aim of this study is to determine the incidence of IPV in a pregnant multicultural population and to determine the relationship between IPV reported at booking interview and maternal and perinatal outcomes. This is a retrospective population-based data study. We analysed routinely collected data (2006-2016) from the ObstetriX system on a cohort of pregnant women. 33 542 women giving birth in a major health facility in Western Sydney. Incidence of IPV, association with IPV and other psychosocial variables and maternal and perinatal outcomes. 4.3% of pregnant women reported a history of IPV when asked during the routine psychosocial assessment. Fifty-four per cent were not born in Australia, and this had increased significantly over the decade. Women born in New Zealand (7.2%) and Sudan (9.1%) were most likely to report IPV at the antenatal booking visit, with women from China and India least likely to report IPV. Women who reported IPV were more likely to report additional psychosocial concerns including Edinburgh Postnatal Depression Scale scores > 13 (7.6%), thoughts of self-harm (2.4%), childhood abuse (23.6%), and a history of anxiety and depression (34.2%). Women who reported IPV were more likely to be Australian born, smoke and be multiparous and to have been admitted for threatened preterm labour (Adjusted Odds Ratio (AOR) 1.8, 95% CI 1.28 to 2.39). A report of IPV at the first antenatal booking visit is associated with a higher level of reporting on all psychosocial risks, higher antenatal admissions, especially for threatened preterm labour. More research is needed regarding the effectiveness of current IPV screening for women from other countries. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Traumatic physical health consequences of intimate partner violence against women: what is the role of community-level factors?

PubMed Central

2011-01-01

Background Intimate partner violence (IPV) against women is a serious public health issue with recognizable direct health consequences. This study assessed the association between IPV and traumatic physical health consequences on women in Nigeria, given that communities exert significant influence on the individuals that are embedded within them, with the nature of influence varying between communities. Methods Cross-sectional nationally-representative data of women aged 15 - 49 years in the 2008 Nigeria Demographic and Health Survey was used in this study. Multilevel logistic regression analysis was used to assess the association between IPV and several forms of physical health consequences. Results Bruises were the most common form of traumatic physical health consequences. In the adjusted models, the likelihood of sustaining bruises (OR = 1.91, 95% CI = 1.05 - 3.46), wounds (OR = 2.54, 95% CI = 1.31 - 4.95), and severe burns (OR = 3.20, 95% CI = 1.63 - 6.28) was significantly higher for women exposed to IPV compared to those not exposed to IPV. However, after adjusting for individual- and community-level factors, women with husbands/partners with controlling behavior, those with primary or no education, and those resident in communities with high tolerance for wife beating had a higher likelihood of experiencing IPV, whilst mean community-level education and women 24 years or younger were at lower likelihood of experiencing IPV. Conclusions Evidence from this study shows that exposure to IPV is associated with increased likelihood of traumatic physical consequences for women in Nigeria. Education and justification of wife beating were significant community-level factors associated with traumatic physical consequences, suggesting the importance of increasing women's levels of education and changing community norms that justify controlling behavior and IPV.

Sabin-based inactivated poliovirus vaccine(sIPV) is gradually replacing live-attenuated oral polio vaccine(OPV). Sabin-inactivated poliovirus vaccine(sIPV) has played a vital role in reducing economic burden of poliomyelitis and maintaining appropriate antibody levels in the population. However, due to its high cost and limited manufacturing capacity, sIPV cannot reach its full potential for global poliovirus eradication in developing countries. Therefore, to address this situation, we designed this study to evaluate the dose-sparing effects of AS03, CpG oligodeoxynucleotides (CpG-ODN) and polyinosinic:polycytidylic acid (PolyI:C) admixed with sIPV in rats. Our results showed that a combination of 1/4-dose sIPV adjuvanted with AS03 or AS03 with BW006 provides a seroconversion rate similar to that of full-dose sIPV without adjuvant and that, this rate is 5-fold higher than that of 1/4-dose sIPV without adjuvant after the first immunization. The combination of AS03 or AS03 with BW006 as an adjuvant effectively reduced sIPV dose by at least 4-fold and induced both humoral and cellular immune responses. Therefore, our study revealed that the combination of AS03 or AS03 with BW006 is a promising adjuvant for sIPV development.

Prevalence and Impact of Intimate Partner Violence (IPV) Among an Ethnic Minority Population.

The present study examined the prevalence of lifetime experiences of physical and psychological intimate partner violence (IPV) among members of the Turkish ethnic minority population in Flanders. In addition, this study explored how lifetime IPV victimization affects ethnic minority victims' current mental, relational, and sexual well-being. Using a population-based representative sample, data from 392 adult Turkish women and men were investigated. Lifetime experiences of physical violence were reported by 14.3% of the Turkish respondents, while 66.0% reported at least one incidence of psychological abuse. Women were much more likely than men to report physical IPV victimization, but no gender differences were found for psychological IPV. With regard to the impact of IPV, it was found that lifetime IPV experiences do not appear to affect victims' current mental health. However, higher levels of physical and/or psychological IPV victimization were related to increased levels of relationship dissatisfaction, anxious and avoidant attachment orientations, sexual dissatisfaction, sexual dysfunction (with distress), and to decreased levels of sexual communication. These adverse relational and sexual outcomes of IPV victimization were mainly present among women but were also, to a lesser degree, relevant for men. © The Author(s) 2014.

Intimate partner violence and women's economic and non-economic activities in Minya, Egypt.

Intimate partner violence (IPV) against women is widespread, but its implications for their economic and non-economic activities are understudied. Leveraging new data from 564 ever-married women aged 22–65 in rural Minya, Egypt, we estimated logistic regressions and zero-inflated negative binomial regressions to test spillover, compensation, and patriarchal bargaining theories about the influences of women's exposure to IPV on their engagement in and time spent on market, subsistence, domestic, and care work. Supporting compensation theory, exposures to lifetime, recent, and chronic physical or sexual IPV were associated with higher adjusted odds of performing market work in the prior month, and exposures to recent and chronic IPV were associated with higher adjusted odds of performing subsistence work in this period. Supporting compensation and patriarchal bargaining theories, exposures to recent and chronic IPV were associated with more time spent on domestic work in the prior day. Supporting spillover and patriarchal bargaining theories, exposures to lifetime IPV of all forms were associated with lower adjusted odds of performing mostly nonspousal care work in the prior day, and this association was partially mediated by women's generalized anxiety. Women in rural Minya who are exposed to IPV may escalate their housework to fulfill local norms of feminine domesticity while substituting economic activities for nonspousal care work to enhance their economic independence from violent partners.

Skin conductance rises in preparation and recovery to psychosocial stress and its relationship with impulsivity and testosterone in intimate partner violence perpetrators.

Intimate partner violence (IPV) perpetrators were categorized into 2 groups using Gottman et al.'s (1995) typology depending on their skin conductance (SC) reactivity to stress. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II perpetrators present a preparatory hyperreactivity to confront stress. Moreover, impulsivity traits and testosterone (T) levels may modulate SC responses to increase the risk of proneness to violence. In this study, SC response to stress was assessed by comparing IPV perpetrators with non-violent controls while performing a modified version of the Trier Social Stress Test (TSST). Subjects with a history of IPV demonstrated higher non-specific SC responses during the recovery period than the non-violent controls. Nonetheless, there were no differences between groups in the case of mean SC levels. Furthermore, impulsivity and baseline T levels were associated with higher SC level reactivity during a preparation period only in IPV perpetrators, with both relationships being mediated by anger expression. Our results confirm that the IPV perpetrators correspond physiologically to type II and support the validity of SC as a diagnostic indicator for IPV classification. Our findings contribute to the development of effective treatment and prevention programs that could benefit from the use of biological indicators for analyzing the risk of recidivism in IPV perpetrators. © 2013.

To determine the prevalence of various types of domestic violence and to find out the impact of intimate partner violence (IPV) on adoption of contraceptive measures among the women who are victim to this. This questionnaire-based, cross-sectional study was conducted in the department of obstetrics and gynecology of a tertiary care hospital in Delhi. Four hundred and one postpartum females were randomly selected over a period of 5 months and were questioned about their age, parity, educational status, occupation, husband's education, monthly family income, and, if present, IPV in detail. These study participants were enquired about their contraceptive knowledge and use. Sexual violence was seen in 38.4% of the cases, physical violence in 22.4% of the cases, and verbal abuse was seen in nearly 32.7% of the cases. In response to any of the three violence faced, only 23 women (11.79%) reacted by discussing with parents and friends. In 4.61% of the cases, the violence was so severe that she had to inform police. This study showed that higher percentage of women without IPV accepted immediate postpartum contraception methods as compared to those with IPV (35.9% vs. 25%, P = 0.023), but the overall frequency of using contraceptive methods was higher in those with IPV as compared to those without IPV (49% vs. 47%, P = 0.690). IPV is associated with increased contraceptive adoption.

Intimate partner violence (IPV) is a prevalent and pressing public health concern that affects people of all gender and sexual identities. Though studies have identified that male couples may experience IPV at rates as high as or higher than women in heterosexual partnerships, the body of literature addressing this population is still nascent. This study recruited 160 male-male couples in Atlanta, Boston, and Chicago to independently complete individual surveys measuring demographic information, partner violence experience and perpetration, and individual and relationship characteristics that may shape the experience of violence. Forty-six percent of respondents reported experiencing IPV in the past year. Internalized homophobia significantly increased the risk for reporting experiencing, perpetrating, or both for any type of IPV. This study is the first to independently gather data on IPV from both members of male dyads and indicates an association between internalized homophobia and risk for IPV among male couples. The results highlight the unique experiences of IPV in male-male couples and call for further research and programmatic attention to address the exorbitant levels of IPV experienced within some of these partnerships.

Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration. This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health. We used logistic regression to examine the associations of financial stressors and each type of IPV (minor, severe, causing injury), and multinomial logit regression to examine the associations of financial stressors and patterns of co-occurring types of IPV perpetration (only minor; only severe; minor and severe; minor, severe, and causing injury; compared with no perpetration). Fewer men perpetrated threats/minor physical IPV (6.7 %) or severe physical IPV (3.4 %) compared with women (11.4 % and 8.8 %, respectively). However, among physical IPV perpetrators, a higher percentage of men (32.0 %) than women (21.0 %) reported their partner was injured as a result of the IPV. In logistic regression models of each type of IPV perpetration, both the number of stressors experienced and several types of financial stressors were associated with perpetrating each type of IPV. Utilities nonpayment, housing nonpayment, food insecurity, and no phone service were associated with increased odds of perpetrating each form of IPV in adjusted analysis. Eviction was associated with perpetrating severe physical IPV but not threats/minor IPV or IPV causing injury. In multinomial logit regression comparing patterns of IPV perpetration to perpetrating no physical IPV, the relationships of financial stressors were less consistent. Food insecurity was associated with perpetrating only minor physical IPV. Comparatively, overall number of financial stressors and four types of financial stressors (utilities nonpayment, housing nonpayment, food insecurity, and disconnected phone service) were associated with perpetrating all three forms of physical IPV. Combined with prior research, our results suggested interventions to improve financial well-being may be a novel way to reduce physical IPV perpetration.

Immune responses and safety profiles may be affected when vaccines are coadministered. We evaluated the immunogenicity, safety and reactogenicity of a booster dose of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D-conjugate (PHiD-CV; Synflorix GSK Vaccines) and DTPa-IPV-Hib (Pediacel Sanofi Pasteur MSD) when coadministered. We performed booster assessment in a randomized controlled trial in the Netherlands. Of 780 enrolled healthy infants, 774 toddlers participated in the booster phase and received (1:1:1) (1) PHiD-CV + DTPa-HBV-IPV/Hib (Infanrix hexa, GSK Vaccines), (2) PHiD-CV + DTPa-IPV-Hib, or (3) 7-valent pneumococcal conjugate vaccine (7vCRM, Prevenar/Prevnar, Pfizer, Inc.) + DTPa-IPV-Hib at 2, 3, 4 and 11-13 months old. Blood samples were taken postprimary, prebooster, 1 and 12 months postbooster. Antipneumococcal antibody responses were comparable between both PHiD-CV groups, except for serotype 18C (conjugated to tetanus toxoid). Anti-18C antibody geometric mean concentrations (GMCs) were higher when coadministered with DTPa-HBV-IPV/Hib. For each vaccine serotype, the percentages of children with antibody concentration ≥ 0.20 μg/mL were within the same ranges between PHiD-CV groups (93.8%-100%). The same was observed for the percentages of participants with opsonophagocytic activity titer ≥ 8 (90.9%-100%). When comparing both DTPa-IPV-Hib groups, postbooster antidiphtheria antibody GMCs were higher when coadministered with 7vCRM, while antitetanus and antipolyribosyl-ribitol phosphate antibody GMCs were higher with PHiD-CV coadministration. Regardless, antibody levels to these antigens were well above thresholds. Safety and reactogenicity profiles were comparable between groups. Coadministration of a booster dose of PHiD-CV and DTPa-IPV-Hib was immunogenic and well tolerated.

Background. Inactivated polio vaccine (IPV) is necessary for global polio eradication because oral polio vaccine can rarely cause poliomyelitis as it mutates and may fail to provide adequate immunity in immunocompromised populations. However, IPV is unaffordable for many developing countries. Intradermal IPV shows promise as a means to decrease the effective dose and cost of IPV, but prior studies, all using 20% of the standard dose used in intramuscular IPV, resulted in inferior antibody titers. Methods. We randomly assigned 231 adults with well-controlled human immunodeficiency virus infection at a ratio of 2:2:2:1 to receive 40% of the standard dose of IPV intradermally, 20% of the standard dose intradermally, the full standard dose intramuscularly, or 40% of the standard dose intramuscularly. Intradermal vaccination was done using the NanoPass MicronJet600 microneedle device. Results. Baseline immunity was 87%, 90%, and 66% against poliovirus serotypes 1, 2, and 3, respectively. After vaccination, antibody titers increased a median of 64-fold. Vaccine response to 40% of the standard dose administered intradermally was comparable to that of the standard dose of IPV administered intramuscularly and resulted in higher (although not significantly) antibody titers. Intradermal administration had higher a incidence of local side effects (redness and itching) but a similar incidence of systemic side effects and was preferred by study participants over intramuscular administration. Conclusions. A 60% reduction in the standard IPV dose without reduction in antibody titers is possible through intradermal administration. PMID:25567841

Intimate partner violence (IPV) is a critical public health issue that has reached epidemic proportions. Research investigating IPV among young women in India using large-scale population data is lacking. This study examined the prevalence and factors associated with IPV among women aged 15 to 24 years in India through a social-ecological approach. This cross-sectional study analyzed data from the National Family Health Survey, a population-based survey conducted in India from 2005 to 2006. The past-year prevalence of emotional, physical, and sexual forms of IPV, among ever-married women aged 15 to 24 years were computed. Multivariate logistic regression was conducted to evaluate the association of factors at various levels of the social-ecological framework with the past-year experience of emotional, physical, sexual, and any form of IPV. The past-year prevalence of IPV among women aged 15 to 24 years ( n = 16,285) was 29%. Physical IPV was the most common, affecting 23% in the past year. The past-year prevalence of sexual IPV among women aged 15 to 24 years at 9.5% was higher than older women. Individual factors significantly associated with the past-year experience of all forms of IPV were the young age at first marriage, parental IPV, and ever had a terminated pregnancy. At the relationship level, husband's controlling behaviors, his consumption of alcohol, and experience of violence from other family members were positively associated with all forms of IPV in the past year. Poverty and acceptance of IPV increased the women's odds of experiencing IPV. IPV was associated with multiple factors occurring at all levels of the social-ecological framework. Actions to prevent and eliminate IPV in India demand multidisciplinary and collaborative efforts that are tailored specifically for adolescents and young women. It is imperative to protect the girls and young women from IPV; it protects the future of India.

Sensors utilize a large number of heterogeneous technologies for a varied set of application environments. The sheer number of devices involved requires that this Internet be the Future Internet, with a core network based on IPv6 and a higher scalability in order to be able to address all the devices, sensors and things located around us. This capability to connect through IPv6 devices, sensors and things is what is defining the so-called Internet of Things (IoT). IPv6 provides addressing space to reach this ubiquitous set of sensors, but legacy technologies, such as X10, European Installation Bus (EIB), Controller Area Network (CAN) and radio frequency ID (RFID) from the industrial, home automation and logistic application areas, do not support the IPv6 protocol. For that reason, a technique must be devised to map the sensor and identification technologies to IPv6, thus allowing homogeneous access via IPv6 features in the context of the IoT. This paper proposes a mapping between the native addressing of each technology and an IPv6 address following a set of rules that are discussed and proposed in this work. Specifically, the paper presents a technology-dependent IPv6 addressing proxy, which maps each device to the different subnetworks built under the IPv6 prefix addresses provided by the internet service provider for each home, building or user. The IPv6 addressing proxy offers a common addressing environment based on IPv6 for all the devices, regardless of the device technology. Thereby, this offers a scalable and homogeneous solution to interact with devices that do not support IPv6 addressing. The IPv6 addressing proxy has been implemented in a multi-protocol card and evaluated successfully its performance, scalability and interoperability through a protocol built over IPv6. PMID:23686145

Prospective study on the reciprocal relationship between intimate partner violence and depression among women in Korea.

PubMed

Kim, Jinseok; Lee, Joohee

2013-12-01

This study aimed to examine the bi-directional relationship between intimate partner violence (IPV) and depression using prospective data. Data from the Korean Welfare Panel Study (KOWEPS) were used to test whether IPV was associated with an increased overall level of depression and with the rate of change over time in depressive symptoms and whether this model of change in depressive symptoms was associated with subsequent incidences of IPV. This study utilized data from 3153 married women who participated in the KOWEPS from 2006 through 2009. The KOWEPS is a panel study of a nationally representative sample of Korean households. The women's responses to multiple questions adopted from the Conflict Tactics Scale (CTS) were used to create a dichotomous IPV variable at Wave1 and Wave4. The CESD-11 was used to measure the women's level of depression. We utilized a latent growth model (LGM) of depression using IPV at Wave1 as a predictor and IPV at Wave4 as an outcome predicted by the model parameters of the LGM of depression. We found that after controlling for the effects of age, education, social support and income, IPV at Wave1 was positively associated with overall depression levels and negatively associated with the growth rate of depression. Further, IPV at Wave4 was associated with the intercept and the slope of the depression LGM and with IPV at Wave1. The overall model fit the data well. This study indicated that experiencing IPV influences a woman's level of depression in terms of its overall level and rate of change, which, in turn, influences the victim's likelihood of experiencing subsequent IPV.

Posttraumatic stress, partner violence victimization, and harmful drinking: risk factors for relationship discord in new parents.

PubMed

Sotskova, Alina; Woodin, Erica M

2013-11-01

The first year of parenthood can be a stressful time, especially for high-risk couples. Symptoms of posttraumatic stress (PTS) have been associated with decreased intimacy, communication, and relationship adjustment, yet there is a lack of research on how PTS symptoms might affect couples in early parenthood. Furthermore, there is little evidence regarding the way in which PTS symptoms may affect couples above and beyond known risk factors such as intimate partner violence (IPV) and harmful alcohol use. The current study investigated how PTS symptoms were related to new parents' relationship satisfaction in the context of IPV and harmful drinking. Ninety-eight heterosexual couples filled out questionnaires 1 year after the birth of their first child. Hierarchical multiple regression analyses indicated that, for men, PTS symptoms predicted lower relationship satisfaction over and above IPV victimization and harmful drinking. However, for women, psychological IPV victimization was the only significant multivariate predictor. In addition, for men, PTS symptoms interacted with harmful drinking to predict poorer relationship satisfaction. The results suggest that women's relationship satisfaction is particularly linked to psychological IPV victimization during early parenthood, whereas men's relationship satisfaction is particularly associated with their own harmful drinking and PTS symptoms. Implications are discussed.

THERAPIST PERCEPTIONS OF INTIMATE PARTNER VIOLENCE: A REPLICATION OF HARWAY AND HANSEN2019;S STUDY AFTER MORE THAN A DECADE

More than a decade ago, Hansen, Harway, and Cervantes (1991) and Harway and Hansen (1993) conducted a research study examining mental health providers’ ability to accurately perceive violence within couples presenting for therapy and to intervene in a manner in which to reduce the risk of danger to couples. The results were alarming, with 40% of therapists sampled failing to perceive intimate partner violence (IPV) and virtually no therapists intervening to reduce the risk of lethality. Harway and colleagues questioned how well-trained and informed therapists were in assessing IPV. The present study replicates Harway and colleagues’ study with the expectation that, over a decade later, therapists are better prepared to accurately identify IPV issues and intervene effectively to reduce the risk of lethality. Reproducing the two main procedures used in the original study, 111 psychologists, clinical social workers, and marriage and family therapists were asked to respond to a survey. Results show that therapists have indeed improved their ability to identify IPV issues. Twenty percent of therapists predicted an increase in conflict, compared to 4% in the original sample. However, almost no therapists accurately predicted lethality in either study. Implications concerning IPV training for therapists are discussed. PMID:24729677

Intimate Partner Violence Victimization in LGBT Young Adults: Demographic Differences and Associations with Health Behaviors.

Intimate partner violence (IPV) is an important public health problem with high prevalence and serious costs. Although literature has largely focused on IPV among heterosexuals, studies have recently begun examining IPV in LGBT samples, with mounting evidence suggesting IPV may be more common among LGBT individuals than heterosexuals. Less research has examined the specific health consequences of IPV in this population, particularly across time and among young people, and it remains unclear whether experiences of IPV differ between subgroups within the LGBT population (e.g. race, gender identity, and sexual orientation). An ethnically diverse sample of 172 LGBT young adults completed self-report measures of IPV, sexual behavior, mental health, and substance abuse at two time points (4- and 5-year follow-up) of an ongoing longitudinal study of LGBT youth. IPV was experienced non-uniformly across demographic groups. Specifically, female, male-to-female transgender, and Black/African-American young adults were at higher risk compared to those who identified as male, female-to-male transgender, and other races. Being a victim of IPV was associated with concurrent sexual risk taking and prospective mental health outcomes but was not associated with substance abuse. Demographic differences in IPV found in heterosexuals were replicated in this LGBT sample, though additional research is needed to clarify why traditional risk factors found in heterosexual young people may not translate to LGBT individuals. Studies examining the impact of IPV on negative outcomes and revictimization over time may guide our understanding of the immediate and delayed consequences of IPV for LGBT young people.

We describe and compare the baseline rates of victimization and perpetration of three forms of intimate partner violence (IPV)—psychological, physical, and sexual—among sexually active men (n = 1,113) and women (n = 226) enrolled in an ongoing cluster-randomized HIV and gender-based violence prevention trial in Dar es Salaam, Tanzania. IPV was measured using a modified version of the World Health Organization Violence Against Women instrument. We assess the degree to which men and women report overlapping forms of IPV victimization and perpetration. Sociodemographic and other factors associated with increased risk of victimization and perpetration of IPV are examined. Within the last 12 months, 34.8% of men and 35.8% of women reported any form of IPV victimization. Men were more likely than women to report perpetrating IPV (27.6% vs. 14.6%, respectively). We also found high rates of co-occurrence of IPV victimization and perpetration with 69.7% of male perpetrators and 81.8% of female perpetrators also reporting victimization during the last year. Among men, having ever consumed alcohol and experiencing childhood violence were associated with increased risk of most forms of IPV. Younger women were more likely to report perpetrating IPV than older women. We found evidence of gender symmetry with regard to most forms of IPV victimization, but men reported higher rates of IPV perpetration than women. Given the substantial overlap between victimization and perpetration reported, our findings suggest that IPV may be bidirectional within relationships in this setting and warrant further investigation. Implications for interventions are discussed. PMID:26802044

To investigate the prescription of potentially addictive drugs, including analgesics and central nervous system depressants, to women who had experienced intimate partner violence (IPV). Prospective population-based cohort study. Information about IPV from the Oslo Health Study 2000/2001 was linked with prescription data from the Norwegian Prescription Database from 1 January 2004 through 31 December 2009. The study included 6081 women aged 30-60 years. Prescription rate ratios (RRs) for potentially addictive drugs derived from negative binomial models, adjusted for age, education, paid employment, marital status, chronic musculoskeletal pain, mental distress and sleep problems. Altogether 819 (13.5%) of 6081 women reported ever experiencing IPV: 454 (7.5%) comprised physical and/or sexual IPV and 365 (6.0%) psychological IPV alone. Prescription rates for potentially addictive drugs were clearly higher among women who had experienced IPV: crude RRs were 3.57 (95% CI 2.89 to 4.40) for physical/sexual IPV and 2.13 (95% CI 1.69 to 2.69) for psychological IPV alone. After full adjustment RRs were 1.83 (1.50 to 2.22) for physical/sexual IPV, and 1.97 (1.59 to 2.45) for psychological IPV alone. Prescription rates were increased both for potentially addictive analgesics and central nervous system depressants. Furthermore, women who reported IPV were more likely to receive potentially addictive drugs from multiple physicians. Women who had experienced IPV, including psychological violence alone, more often received prescriptions for potentially addictive drugs. Researchers and clinicians should address the possible adverse health and psychosocial impact of such prescription and focus on developing evidence-based healthcare for women who have experienced IPV.

Intimate partner violence and housing instability.

The mental and physical health consequences of intimate partner violence (IPV) have been well established, yet little is known about the impact of violence on a woman's ability to obtain and maintain housing. This cross-sectional study examines the relationship between recent IPV and housing instability among a representative sample of California women. It is expected that women who have experienced IPV will be at increased risk for housing instability as evidenced by: (1) late rent or mortgage, (2) frequent moves because of difficulty obtaining affordable housing, and/or (3) without their own housing. Data were taken from the 2003 California Women's Health Survey, a population-based, random-digit-dial, annual probability survey of adult California women (N=3619). Logistic regressions were used to predict housing instability in the past 12 months, adjusting for the following covariates; age, race/ethnicity, education, poverty status, marital status, children in the household, and past year IPV. In the multivariate model, age, race/ethnicity, marital status, poverty, and IPV were significant predictors of housing instability. After adjusting for all covariates, women who experienced IPV in the last year had almost four times the odds of reporting housing instability than women who did not experience IPV (adjusted odds ratio=3.98, 95% confidence interval: 2.94-5.39). This study found that IPV was associated with housing instability among California women. Future prospective studies are needed to learn more about the nature and direction of the relationship between IPV and housing instability and the possible associated negative health consequences.

Tanzanian Couples' Perspectives on Gender Equity, Relationship Power, and Intimate Partner Violence: Findings from the RESPECT Study

Intimate partner violence (IPV) is widely prevalent in Tanzania. Inequitable gender norms manifest in men's and women's attitudes about power and decision making in intimate relationships and are likely to play an important role in determining the prevalence of IPV. We used data from the RESPECT study, a randomized controlled trial that evaluated an intervention to prevent sexually transmitted infections in a cohort of young Tanzanian men and women, to examine the relationship between couples' attitudes about IPV, relationship power, and sexual decision making, concordance on these issues, and women's reports of IPV over 12 months. Women expressed less equitable attitudes than men at baseline. Over time, participants' attitudes tended to become more equitable and women's reports of IPV declined substantially. Multivariable logistic regression analyses suggested that inequitable attitudes and couple discordance were associated with higher risk of IPV. Our findings point to the need for a better understanding of the role that perceived or actual imbalances in relationship power have in heightening IPV risk. The decline in women's reports of IPV and the trend towards gender-equitable attitudes indicate that concerted efforts to reduce IPV and promote gender equity have the potential to make a positive difference in the relatively short term.

Purpose Because Intimate partner violence (IPV) may disproportionately impact women’s quality of life (QOL) when undergoing cancer treatment, women experiencing IPV were hypothesized to have (a) more symptoms of depression or stress and (b) lower QOL as measured with the Functional Assessment of Cancer Therapy (FACT-B) and Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) Scales relative to those never experiencing IPV. Methods Women, ages 18–79, who were included in one of two state cancer registries from 2009–2015 with a recent incident, primary, invasive biopsy-confirmed cancer diagnosis were recruited and asked to complete a phone interview, within 12 months of diagnosis. This interview measured IPV by timing (current and past) and type (physical, sexual, psychological), socio-demographics, and health status. Cancer registries provided consenting women’s cancer stage, site, date of diagnosis, and age. Results In this large cohort of 3,278 women who completed a phone interview, 1,221 (37.3%) disclosed lifetime IPV (10.6% sexual, 24.5% physical, and 33.6% psychological IPV). Experiencing IPV (particularly current IPV) was associated with poorer cancer-related QOL defined as having more symptoms of depression and stress after cancer diagnosis and lower FACIT-SP and FACT scores than women not experiencing IPV and controlling for confounders including demographic factors, cancer stage, site and number of comorbid conditions. Current IPV was more strongly associated with poorer QOL. When compared with those experiencing past IPV (and no IPV), women with cancer who experienced current IPV had significantly higher depression and stress symptoms scores and lower FACIT-SP and FACT-G scores indicating poorer QOL for all domains. While IPV was not associated with being diagnosed at a later cancer stage, current IPV was significantly associated with having more than one comorbid physical conditions at interview (adjusted rate ratio = 1.35; 95% confidence interval: 1.19–1.54) and particularly for women diagnosed with cancer when <55 years of age. Conclusions Current and past IPV were associated with poorer mental and physical health functioning among women recently diagnosed with cancer. Including clinical IPV screening may improve women’s cancer-related quality of life. PMID:27943059

Intimate partner violence (IPV) often includes economic abuse as one tactic commonly used by an abuser; unfortunately, there is a lack of empirical understanding of economic abuse. Additionally, research is limited on the predictors of economic self-sufficiency in the lives of women experiencing IPV. This paper furthers our knowledge about economic abuse and its relationship with economic self-sufficiency by presenting the results from an exploratory study with IPV survivors participating in a financial literacy program. Of the 120 individuals who participated in the first wave, 94% experienced some form of economic abuse, which also correlated highly with other forms of IPV. Seventy-nine percent experienced some form of economic control, 79% experienced economic exploitative behaviors, and 78% experienced employment sabotage. MANOVA results also indicated that economic control differed significantly based on education with those with a high school education experiencing higher rates than those with less than high school education or those with some college. Finally, results from the OLS regressions indicated that experiencing any form of economic abuse as well as economic control significantly predicted a decrease in economic self sufficiency. Implications suggest that advocates should assess for economic abuse when working with survivors and should be prepared to offer financial tools to increase survivors' economic self-sufficiency. Policymakers should understand the ramifications of economic abuse and create policies that support survivors and prohibit economic abuse. Finally, more research is needed to fully understand economic abuse and its impact on survivors and their economic self-sufficiency.

We conducted a population-based prospective cohort study to help elucidate the predictive relationship between a maternal prebirth self-reported history of intimate partner violence (IPV) and any postbirth reported allegation to Child Protective Services (CPS) by age 2. We linked data from the 2009-2010 Alaska Pregnancy Risk Assessment Monitoring System with CPS data through 2012. Among this cohort, we found that 8.0%w self-reported experiencing IPV 12 months prior or during pregnancy, and 8.0%w of the offspring experienced at least one CPS report of alleged maltreatment during the study period. The predictive relationship varied by maternal educational attainment. Among mothers with 12+ years education completed, the odds of a CPS report were 3.9 times compared to those with no IPV, while among mothers with <12 years education completed, no association was noted. These results suggest that for a subset of Alaskan families, maternal history of IPV is a strong independent predictor of future CPS contact. © The Author(s) 2015.

Intimate partner violence (IPV) has only attracted limited attention in Korea despite numerous studies in Western countries that indicate IPV is associated with depressive symptoms. This study examined the association of IPV with depressive symptoms and suicidal ideation as moderated by the perceived gender roles of married women in South Korea. We analyzed a data set of 4659 married females from the 8th wave of the Korea Welfare Panel Study. Participants were categorized into three groups of non-IPV, non-physical IPV, and physical IPV. The presence of depressive symptoms and suicidal ideation was then used to predict mental health outcomes. Logistic regression helped to investigate the association of IPV and mental health. Furthermore, an interactive regression of IPV and perceived gender roles was also done. Each type of IPV (non-physical and physical) was significantly associated with depressive symptoms (Odds ratios [ORs]: 1.65 and 4.34; 95% confidence interval [CIs]: 1.28-2.13 and 2.71-7.28, respectively) and suicidal ideation (ORs: 1.40 and 3.84; 95% CIs: 1.06-1.85 and 2.32-6.36, respectively) after adjusting for covariates. In addition, women who experienced IPV and reported having traditional gender roles were also more likely to report depressive symptoms (OR: 4.59; 95% CI: 2.90-7.28) and suicidal ideation (OR: 7.28; 95% CI: 3.56-14.87). Research findings indicate an increasingly marked pattern of work-family conflict in regard to the relationship between traditional gender roles and the effect of IPV on the mental health of women. Policy efforts are needed to reduce IPV as a mental health risk factor and address paternalistic traditions deeply rooted in Korean society that place women in an inferior family status.

Background Evidence from developing countries regarding the association between gender inequity and intimate partner violence (IPV) victimization in women has been suggestive but inconclusive. Using nationally representative population-based data from Bangladesh, we examined the association between multidimensional aspects of gender inequity and the risk of IPV. Methods We used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 4,467 married women. The main explanatory variable was gender inequity, which reflects the multidimensional aspects of women's autonomy and the relationship inequality between women and their partner. The experience of physical and/or sexual IPV was the main outcome variable of interest. Results Over 53% of married Bangladeshi women experienced physical and/or sexual violence from their husbands. In the adjusted models, women who had a higher level of autonomy (adjusted odds ratio [AOR] 0.48; 99% confidence interval [CI] 0.37–0.61), a particularly high level of economic-decision-making autonomy (AOR 0.12; 99% CI 0.08–0.17), and a higher level of non-supportive attitudes towards wife beating or raping (AOR 0.61; 99% CI 0.47–0.83) were less likely to report having experienced IPV. Education level, age at marriage, and occupational discrepancy between spouses were also found to be significant predictors of IPV. Conclusions In conclusion, dimensions of gender inequities were significant predictors of IPV among married women in Bangladesh. An investigation of the causal link between multidimensional aspects of gender inequity and IPV will be critical to developing interventions to reduce the risk of IPV and should be considered a public health research priority.

Inactivated polio vaccine (IPV) is necessary for global polio eradication because oral polio vaccine can rarely cause poliomyelitis as it mutates and may fail to provide adequate immunity in immunocompromised populations. However, IPV is unaffordable for many developing countries. Intradermal IPV shows promise as a means to decrease the effective dose and cost of IPV, but prior studies, all using 20% of the standard dose used in intramuscular IPV, resulted in inferior antibody titers. We randomly assigned 231 adults with well-controlled human immunodeficiency virus infection at a ratio of 2:2:2:1 to receive 40% of the standard dose of IPV intradermally, 20% of the standard dose intradermally, the full standard dose intramuscularly, or 40% of the standard dose intramuscularly. Intradermal vaccination was done using the NanoPass MicronJet600 microneedle device. Baseline immunity was 87%, 90%, and 66% against poliovirus serotypes 1, 2, and 3, respectively. After vaccination, antibody titers increased a median of 64-fold. Vaccine response to 40% of the standard dose administered intradermally was comparable to that of the standard dose of IPV administered intramuscularly and resulted in higher (although not significantly) antibody titers. Intradermal administration had higher a incidence of local side effects (redness and itching) but a similar incidence of systemic side effects and was preferred by study participants over intramuscular administration. A 60% reduction in the standard IPV dose without reduction in antibody titers is possible through intradermal administration. © The Author 2015.

Cost and supply constraints are key challenges in the use of inactivated polio vaccine (IPV). Dose reduction through adsorption to aluminium hydroxide (Al) is a promising option, and establishing its effectiveness in the target population is a crucial milestone in developing IPV-Al. The aim of this clinical trial was to show the non-inferiority of three IPV-Al vaccines to standard IPV. In this phase 2, non-inferiority, observer-blinded, randomised, controlled, single-centre trial in the Dominican Republic, healthy infants aged 6 weeks, not previously polio vaccinated, were allocated after computer-generated randomisation by block-size of four, to receive one of four IPV formulations (three-times reduced dose [1/3 IPV-Al], five-times reduced dose [1/5 IPV-Al], ten-times reduced dose [1/10 IPV-Al], or IPV) intramuscularly in the thigh at 6, 10, and 14 weeks of age. The primary outcome was seroconversion for poliovirus types 1, 2, and 3 with titres more than or equal to four-fold higher than the estimated maternal antibody titre and more than or equal to 8 after three vaccinations. Non-inferiority was concluded if the lower two-sided 90% CI of the seroconversion rate difference between IPV-Al and IPV was greater than -10%. The safety analyses were based on the safety analysis set (randomly assigned participants who received at least one trial vaccination) and the immunogenicity analyses were based on the per-protocol population. This study is registered with ClinicalTrials.gov registration, number NCT02347423. Between Feb 2, 2015, and Sept 26, 2015, we recruited 824 infants. The per-protocol population included 820 infants; 205 were randomly assigned to receive 1/3 IPV-Al, 205 to receive 1/5 IPV-Al, 204 to receive 1/10 IPV-Al, and 206 to receive IPV. The proportion of individuals meeting the primary endpoint of seroconversion for poliovirus types 1, 2, and 3 was already high for the three IPV-Al vaccines after two vaccinations, but was higher after three vaccinations (ie, after completion of the expanded programme of immunisation schedule): 1/3 IPV-Al 98·5% (n=202, type 1), 97·6% (n=200; type 2), and 99·5% (n=204, type 3); 1/5 IPV-Al: 99·5% (n=204, type 1), 96·1% (n=197, type 2), and 98·5% (n=202, type 3); and 1/10 IPV-Al: 98·5% (n=201, type 1), 94·6% (n=193, type 2), and 99·5% (n=203, type 3). All three IPV-Al were non-inferior to IPV, with absolute differences in percentage seroconversion for each poliovirus type being greater than -10% (1/3 IPV-Al type 1, -1·46 [-3·60 to 0·10], type 2, -0·98 [-3·62 to 1·49], and type 3, -0·49 [-2·16 to 0·86]; 1/5 IPV-Al type 1, -0·49 [-2·16 to 0·86], type 2, -2·45 [-5·47 to 0·27], and type 3, -1·46 [-3·60 to 0·10]; and 1/10 IPV-Al type 1, -1·47 [-3·62 to 0·10], type 2, -3·94 [-7·28 to -0·97], and type 3, -0·49 [-2·17 to 0·86]). Three serious adverse events occurred that were unrelated to the vaccine. The lowest dose (1/10 IPV-Al) of the vaccine performed well both after two and three doses. Based on these results, this new vaccine is under investigation in phase 3 trials. Bill & Melinda Gates Foundation. Copyright © 2017 The Author(s). Published by Elsevier Ltd.

A candidate inactivated poliovirus vaccine derived from live-attenuated Sabin strains (sIPV), which are used in the oral poliovirus vaccine (OPV), was prepared in a large-production scale. The modification of viral antigenic epitopes during the formalin inactivation process was investigated by capture ELISA assays using type-specific and antigenic site-specific monoclonal antibodies (MoAbs). The major antigenic site 1 was modified during the formalin inactivation of Sabin 1. Antigenic sites 1-3 were slightly modified during the formalin inactivation of Sabin 2 strain. Sites 1 and 3 were altered on inactivated Sabin 3 virus. These alterations were different to those shown by wild-type Saukett strain, used in conventional IPV (cIPV). It has been previously reported that type 1 sIPV showed higher immunogenicity to type 1 cIPV whereas types 2 and 3 sIPV induced lower level of immunogenicity than their cIPV counterparts. Our results suggest that the differences in epitope structure after formalin inactivation may account, at least in part, for the observed differences in immunogenicity between Sabin and wild-type inactivated poliovaccines.

The aim of this study was to examine the relationship of maternal interpersonal violence-related posttraumatic stress disorder (IPV-PTSD), associated neural activity in response to mother-child relational stimuli, and child psychopathology indicators at child ages 12–42 months and one year later. The study tested the hypothesis that decreased maternal neural activity in regions that subserve emotion regulation would be associated with child symptoms associated with emotional dysregulation at both time points. Functional magnetic resonance imaging of 42 mothers with or without violence-exposure and associated IPV-PTSD were assessed. Their child’s life-events and symptoms/behaviors indicative of high-risk subsequent PTSD diagnosis on a maternal-report questionnaire were measured one year later. Maternal IPV-PTSD severity was significantly associated with decreased ventromedial prefrontal cortex (vmPFC) activation in response to mother-child relational stimuli. Maternal IPV-PTSD severity and decreased vmPFC activation were then significantly associated with a child attachment disturbance at 12–42 months and symptoms/behaviors one year later, that were correlated with emotional dysregulation and risk for child PTSD. Maternal IPV-PTSD and child exposure to IPV were both predictive of child PTSD symptoms with maternal IPV-PTSD likely mediating the effects of child IPV exposure on child PTSD symptoms. These findings suggest that maternal IPV-PTSD severity and associated decreased vmPFC activity in response to mother-child relational stimuli are predictors of child psychopathology by age 12–42 months and one-year later. Significant findings in this paper may well be useful in understanding how maternal top-down cortico-limbic dysregulation promotes intergenerational transmission of IPV and related psychopathology and, thus should be targeted in treatment.

Enhanced Predictive Handover for Fast Proxy Mobile IPv6

NASA Astrophysics Data System (ADS)

Jeon, Seil; Kang, Namhi; Kim, Younghan

Proxy Mobile IPv6 (PMIPv6) has been proposed in order to overcome the limitations of host-based mobility management in IPv6 networks. However, packet losses during doing handover are still a problem. To solve this issue, several schemes have been developed, and can be classified into two approaches: predictive and reactive handover. Both approaches commonly use bi-directional tunnel between mobile access gateways (MAGs). In predictive schemes especially, mobility support for a mobile node (MN) is triggered by simplified link signal strength. Thereafter, the MN sends handover notification to its serving MAG, and is then able to initiate packet forwarding. Therefore, if the MN moves toward an unexpected MAG that does not have any pre-established tunnel with the serving MAG, it may lead to packet losses. In this paper, we define this problem as Early Packet Forwarding (EPF). As a solution, we propose an enhanced PMIPv6 scheme using two-phase tunnel control based on the IEEE 802.21 Media Independent Handover (MIH).

Towards the Development of an Intimate Partner Violence Screening Tool for Gay and Bisexual Men

Introduction: Recent research suggests that gay and bisexual men experience intimate partner violence (IPV) at rates comparable to heterosexual women. However, current screening tools used to identify persons experiencing IPV were largely created for use with heterosexual women. Given the high prevalence of IPV among gay and bisexual men in the United States, the lack of IPV screening tools that reflect the lived realities of gay and bisexual men is problematic.This paper describes the development of a short-form IPV screening tool intended to be used with gay and bisexual men. Methods: A novel definition of IPV, informed by formative Focus Group Discussions, was derived from a quantitative survey of approximately 1,100 venue-recruited gay and bisexual men. From this new definition, a draft IPV screening tool was created. After expert review (n=13) and cognitive interviews with gay and bisexual men (n=47), a screening tool of six questions was finalized.A national, online-recruited sample (n=822) was used to compare rates of IPV identified by the novel tool and current standard tools. Results: The six-item, short-form tool created through the six-stage research process captured a significantly higher prevalence of recent experience of IPV compared to a current and commonly used screening tool (30.7% versus 7.5%, p<0.05). The novel short-form tool described additional domains of IPV not currently found in screening tools, including monitoring behaviors, controlling behaviors, and HIV-related IPV. The screener takes less than five minutes to complete and is 6th grade reading level. Conclusion: Gay and bisexual men experiencing IPV must first be identified before services can reach them. Given emergent literature that demonstrates the high prevalence of IPV among gay and bisexual men and the known adverse health sequela of experiencing IPV, this novel screening tool may allow for the quick identification of men experiencing IPV and the opportunity for referrals for the synergistic management of IPV. Future work should focus on implementing this tool in primary or acute care settings in order to determine its acceptability and its feasibility of use more broadly. PMID:23997849

Six different adjuvants, each in combination with inactivated polio vaccine (IPV) produced with attenuated Sabin strains (sIPV), were evaluated for their ability to enhance virus neutralizing antibody titers (VNTs) in the rat potency model. The increase of VNTs was on average 3-, 15-, 24-fold with adjuvants after one immunization (serotype 1, 2, and 3, respectively). Also after a boost immunization the VNTs of adjuvanted sIPV were on average another 7- 20- 27 times higher than after two inoculations of sIPV without adjuvant. The results indicate that it is feasible to increase the potency of inactivated polio vaccines by using adjuvants. PMID:23313617

To ensure that developing countries have the option to produce inactivated poliovirus vaccine (IPV), the Global Polio Eradication Initiative has promoted the development of an IPV using Sabin poliovirus strains (Sabin IPV). This trial assessed the reactogenicity and immunogenicity of Sabin IPV and adjuvanted Sabin IPV in healthy adults in Cuba. This is a randomized, controlled phase I trial, enrolling 60 healthy (previously vaccinated) male human volunteers, aged 19-23 years to receive one dose of either Sabin IPV (20:32:64 DU/dose), adjuvanted Sabin IPV (10:16:32 DU/dose), or conventional Salk IPV (40:8:32 DU/dose). The primary endpoint for reactogenicity relied on monitoring of adverse events. The secondary endpoint measured boosting immune responses (i.e. seroconversion or 4-fold rise) of poliovirus antibody, assessed by neutralization assays. Sixty subjects fulfilled the study requirements. No serious adverse events reported were attributed to trial interventions during the 6-month follow-up period. Twenty-eight days after vaccination, boosting immune responses against poliovirus types 1-3 were between 90% and 100% in all vaccination groups. There was a more than 6-fold increase in median antibody titers between pre- and post-vaccination titers in all vaccination groups. Both Sabin IPV and adjuvanted Sabin IPV were well tolerated and immunogenic against all poliovirus serotypes. This result suggests that the aluminum adjuvant may allow a 50% (or higher) dose reduction. Copyright © 2014. Published by Elsevier Ltd.

Edwards, Katie M; Littleton, Heather L; Sylaska, Kateryna M; Crossman, Annie L; Craig, Meghan

2016-09-01

This paper provides an overview of a conceptual model that integrates theories of social ecology, minority stress, and community readiness to better understand risk for and outcomes of intimate partner violence (IPV) among LGBTQ+ college students. Additionally, online survey data was collected from a sample of 202 LGBTQ+ students enrolled in 119 colleges across the United States to provide preliminary data on some aspects of the proposed model. Results suggested that students generally thought their campuses were low in readiness to address IPV; that is, students felt that their campuses could do more to address IPV and provide IPV services specific to LGBTQ+ college students. Perceptions of greater campus readiness to address IPV among LGBTQ+ college students was significantly and positively related to a more favorable LGBTQ+ campus climate and a greater sense of campus community. Additionally, IPV victims were more likely to perceive higher levels of campus community readiness than non-IPV victims. There was no association between IPV perpetration and perceptions of campus community readiness. Greater sense of community was marginally and inversely related to IPV victimization and perpetration. Sense of community and LGBTQ+ campus climate also varied to some extent as a function of region of the country and type of institution. Implications for further development and refinement of the conceptual model, as well as future research applying this model to better understand IPV among sexual minority students are discussed. © Society for Community Research and Action 2016.

This article explores the health implications of partner violence against women in Ghana using data from northern Ghana. Face-to-face structured interviews were conducted with a sample of 443 women contacted at health facilities in the northern region. Results indicate that 7 out of 10 women have experienced intimate partner violence (IPV) within the past 12 months; 62% had experienced psychological violence, 29% had experienced physical violence, and 34% had experienced sexual violence. Participants reported health problems associated with violence, including injury, thoughts of suicide, sleep disruption, and fear of partner (FP). Logistic regression analyses showed that women who reported physical, psychological, and sexual violence, respectively, had 3.94 times, 10.50 times, and 2.21 times the odds of reporting thoughts of suicide, whereas the odds that women who reported physical, psychological, and sexual violence would report sleep disruption were 4.82 times higher, 4.44 times higher, and 2.50 times higher, respectively. However, only physical and psychological violence predicted the odds of FP. This study shows that IPV is a health risk factor among women in Ghana. Measures that should be designed to improve the health of women experiencing marital violence are suggested.

Intimate partner violence (IPV) occurs across the world, in various cultures, and affects people across societies irrespective of economic status or gender. Most data on IPV before World Health Organization multicountry study (WHOMCS) usually came from sources other than the military. Result of this study will contribute to the existing body of knowledge and may serve as a baseline for future studies in military populations. This study compares the prevalence of the different types of IPV against women in military and civilian communities in Abuja, Nigeria. Using a multistage sampling technique, 260 women who had intimate male partners were selected from military and civilian communities of Abuja. Collected data on personal characteristics and different types of IPV experienced were analyzed to demonstrate comparison of the association between the different forms of IPV and the respondents' sociodemographic and partner characteristics in the two study populations using percentages and χ-square statistics, and P-value was assumed to be significant at ≤0.05. The prevalence of the four major types of IPV was higher among the military respondents than among civilians: controlling behavior, 37.1% versus 29.1%; emotional/psychological abuse, 42.4% versus 13.4%; physical abuse, 19.7% versus 5.9%, and sexual abuse, 9.2% versus 8.8%. Significantly more respondents from the military population (59 [45.4%]) compared to civilians (21 [19.4%]) were prevented by their partners from seeing their friends (P=0.000). The situation is reversed with regard to permission to seek health care for self, with civilians reporting a significantly higher prevalence (35 [32.4%]) than did military respondents (20 [15.4%]) (P=0.002). The military respondents were clearly at a higher risk of experiencing all the variants of emotional violence than the civilians (P=0.00). The commonest form of physical violence against women was "being slapped or having something thrown at them, that could hurt", which was markedly higher in the military (43 [33.1%]) than in the civilian population (10 [9.3%]), (P<0.05). IPV is a significant public health problem in Abuja, and the military population is clearly at a higher risk of experiencing all forms of IPV compared to the civilian population. The military should encourage and finance research on effect of military operations and posttraumatic stress disorders on family relationships with a view of developing evidence-based treatment models for military personnel.

Adult Attachment Styles, Destructive Conflict Resolution, and the Experience of Intimate Partner Violence.

2016-04-01

Although there is ample evidence linking insecure attachment styles and intimate partner violence (IPV), little is known about the psychological processes underlying this association, especially from the victim's perspective. The present study examined how attachment styles relate to the experience of sexual and psychological abuse, directly or indirectly through destructive conflict resolution strategies, both self-reported and attributed to their opposite-sex romantic partner. In an online survey, 216 Spanish undergraduates completed measures of adult attachment style, engagement and withdrawal conflict resolution styles shown by self and partner, and victimization by an intimate partner in the form of sexual coercion and psychological abuse. As predicted, anxious and avoidant attachment styles were directly related to both forms of victimization. Also, an indirect path from anxious attachment to IPV victimization was detected via destructive conflict resolution strategies. Specifically, anxiously attached participants reported a higher use of conflict engagement by themselves and by their partners. In addition, engagement reported by the self and perceived in the partner was linked to an increased probability of experiencing sexual coercion and psychological abuse. Avoidant attachment was linked to higher withdrawal in conflict situations, but the paths from withdrawal to perceived partner engagement, sexual coercion, and psychological abuse were non-significant. No gender differences in the associations were found. The discussion highlights the role of anxious attachment in understanding escalating patterns of destructive conflict resolution strategies, which may increase the vulnerability to IPV victimization. © The Author(s) 2016.

Self-reported exposure to intimate partner violence among women and men in Sweden: results from a population-based survey

PubMed Central

2013-01-01

Background Few population-based studies assessing IPV among randomly selected women and men have been conducted in Sweden. Hence, the aim of the current study was to explore self-reported exposure, associated factors, social and behavioural consequences of and reasons given for using psychological, physical and sexual intimate partner violence (IPV) among women and men residing in Sweden. Methods Cross-sectional postal survey of women and men aged 18–65 years. Bivariate and multivariate logistic regression analyses were used to identify factors associated with exposure to IPV. Results Past-year IPV exposure rates were similar in women and men; however, earlier-in-life estimates were higher in women. Poor to moderate social support, growing up with domestic violence and being single, widowed or divorced were associated with exposure to all forms of IPV in men and women. Women and men tended to report different social consequences of IPV. Conclusions Our finding that women reported greater exposure to IPV earlier-in-life but not during the past year suggests the importance of taking this time frame into account when assessing gender differences in IPV. In-depth, qualitative studies that consider masculinities, femininities power and gender orders would be beneficial for extending and deepening our understanding of the gendered matter of IPV.

This study analyzed data from the Police Stress and Domestic Violence in Police Families in Baltimore, Maryland, 1997-1999 ( N = 753) to examine propositions derived from target congruence theory in the context of intimate partner violence (IPV) victimization experienced by police officers. Specifically, this study tested the influence of target vulnerability, target gratifiability, and target antagonism on IPV victimization. Results from logistic regression models showed that all three theoretical constructs positively and significantly predicted IPV victimization. Results, as well as the study's limitations and directions for future research, are discussed.

Influence of Intimate Partner Violence and Depression on Undergraduate Nursing Students: A Literature Review.

Intimate partner violence (IPV) and dating violence is a significant problem among college-age students. IPV has an associative outcome of depression and lower academic performance, but it is unknown how it relates to undergraduate nursing students. Two literature searches were performed for IPV and depression from a combination of 87 databases including EBSCO, Proquest, Nursing at OVID, Medline, PubMed, CINAHL, PsycARTICLES, JSTOR, SAGE journals, and Google Scholar. Initial results yielded 24,675 research studies on IPV, dating violence, and depression. Forty-eight level-three studies were identified using the John Hopkins School of Nursing evidence-based practice model, including 42 nonexperimental studies, three meta-syntheses, and three governmental studies. Relevant data on the prevalence rates of IPV and depression among nursing students are lacking. IPV and dating violence among college students places them at a higher risk for failure and poor academic performance. [J Nurs Educ. 2017;56(7):397-403.]. Copyright 2017, SLACK Incorporated.

Previous work in this area has focused on the maternal experiences, neglecting to examine paternal effects. The present study aimed to elucidate the role of IPV, power, and equity in parenting and child outcomes in an urban sample of adolescent parents. 159 male and 182 female parents in a relationship were recruited through university-affiliated hospitals. Power, equity, and IPV were measured at 6 months post-partum and were used as predictors for parenting and child outcomes 12 months post-partum using general estimating equations. Gender interactions and mediation effects of depression were also assessed. Higher perceived relationship equity was related to better infant temperament (B = 0.052, SE = 0.023, p = 0.02) whereas higher partner power was related to poorer social development (B = -0.201, SE = 0.088, p = 0.02) and fine motor development (B = -0.195, SE = 0.078, p = 0.01). IPV victimization was associated with poor infant temperament (B = -2.925, SE = 1.083, p = 0.007) and lower parenting competence (B = -3.508, SE = 1.142, p = 0.002). Depression mediated the relationship between IPV and parenting and IPV and infant temperament. No gender effects were found. IPV, inequities, and power imbalances were disadvantageous for parenting and child outcomes. Our results suggest that these dynamics may negatively affect both males and females. Interventions to reduce violence in both partners and promote equity in relationships could benefit couples and their children.

Violence against women is a common form of human rights violation, and intimate partner violence (IPV) appears to be the most significant component of violence. The aim of this study was to examine the association between women decision-making capacity and IPV among Women in Sub-Saharan Africa. The study also looked at how socio-demographic factors also influence IPV among Women in Sub-Saharan Africa. The study made use of pooled data from most recent Demographic and Health Survey (DHS) conducted from January 1, 2010, and December 3, 2016, in 18 countries in Sub-Saharan Africa. For the purpose of the study, only women aged 15-49 were used ( N  = 84,486). Univariate and multivariate logistic regression models were used to investigate the relationship between the explanatory variables and the outcome variable. The odds of reporting ever experienced IPV was higher among women with decision-making capacity [AOR = 1.35; CI = 1.35-1.48]. The likelihood of experiencing IPV was low among young women. Women who belong to other religious groups and Christians were more likely to experience IPV compared to those who were Muslims [AOR = 1.73; CI = 1.65-1.82] and [AOR = 1.87; CI = 1.72-2.02] respectively. Women who have partners with no education [AOR = 1.11; CI = 1.03-1.20], those whose partners had primary education [AOR = 1.34; CI = 1.25-1.44] and those whose partners had secondary education [AOR = 1.22; CI = 1.15-1.30] were more likely to IPV compared to those whose partners had higher education. The odds of experiencing IPV were high among women who were employed compared to those who were unemployed [AOR = 1.33; CI = 1.28-1.37]. The likelihood of the occurrence of IPV was also high among women who were cohabiting compared to those who were married [AOR = 1.16; CI = 1.10-1.21]. Women with no education [AOR = 1.37; CI = 1.24-1.51], those with primary education [AOR = 1.65; CI = 1.50-1.82] and those with secondary education [AOR = 1.50; CI = 1.37-1.64] were more likely to experience IPV compared to those with higher education. Finally, women with poorest wealth status [AOR = 1.28; CI = 1.20-1.37], those with poorer wealth status [AOR = 1.24; CI = 1.17-1.32], those with middle wealth status [AOR = 1.27; CI = 1.20-1.34] and those with richer wealth status [AOR = 1.11; CI = 1.06-1.17] were more likely to IPV compared to women with richest wealth status. Though related socio-demographic characteristics and women decision-making capacity provided an explanation of IPV among women in sub-Saharan Africa, there were differences in relation to how each socio-demographic variable predisposed women to IPV in Sub-Saharan Africa.

Background There is ample evidence that both intimate-partner violence (IPV) and childhood abuse adversely affect the physical and mental health of adult women over the long term. Objective The authors assessed the associations between abuse, symptoms, and mental health utilization. Method The authors performed a cross-sectional survey of 380 adult female, internal-medicine patients. Results Although both IPV and childhood abuse were associated with depressive and physical symptoms, IPV was independently associated with physical symptoms, and childhood abuse was independently associated with depression. Women with a history of childhood abuse had higher odds, whereas women with IPV had lower odds, of receiving care from mental health providers. Conclusion IPV and childhood abuse may have different effects on women’s symptoms and mental health utilization. PMID:19687174

Following achievement of polio eradication, the routine use of all live-attenuated oral poliovirus vaccines should be discontinued. However, the costs per vaccine dose for the alternative inactivated poliovirus vaccine (IPV) are significantly higher and the current production capacity is not sufficient for worldwide distribution of the vaccine. In order to achieve cost-prize reduction and improve affordability, IPV production processes and dose-sparing strategies should be developed to facilitate local manufacture at a relatively lower cost. The use of attenuated Sabin instead of wild-type polio strains will provide additional safety during vaccine production and permits production in low-cost settings. Sabin-IPV is under development by several manufacturers. This article gives an overview of results from clinical trials with Sabin-IPV and discusses the requirements and challenges in the clinical development of this novel IPV.

This study examines the impact of several indicators of neighborhood social ties (e.g., residents' interactions with each other; residents' ability to recognize outsiders) on intimate partner violence (IPV) against women as well as whether neighborhood collective efficacy's impact on IPV is contingent upon such ties. This study used data from 4,151 women (46% Latina, 33% African American, 17% Caucasian, on average 32 years old) in 80 neighborhoods from the Project on Human Development in Chicago Neighborhoods. We estimated a series of random effects hierarchical Bernoulli models to assess the main and interactive effects of neighborhood social ties and collective efficacy on minor and severe forms of IPV against women. Results indicate that certain neighborhood social ties are associated with higher rates of minor forms of IPV against women (but not severe forms of IPV), and collective efficacy does not appear to influence IPV against women, regardless of the level of individual or neighborhood social ties. Unlike street crime, collective efficacy does not significantly reduce IPV against women, even in neighborhoods with strong social ties that may facilitate awareness of the violence. In fact, perpetrators of minor IPV may enjoy some protective benefit in communities with social ties that make neighbors hesitant to intervene in what some might perceive as "private matters."

Gender, Power, and Intimate Partner Violence: A Study on Couples From Rural Malawi

Gender-based power imbalances are perhaps the most compelling underlying explanation for intimate partner violence (IPV) among women in sub-Saharan Africa. However, an overemphasis on female victimization results in an incomplete understanding of men’s experiences as victims and the broader dyadic context in which violence occurs. This study examines the role of three domains of relationship power (power resources, processes, and outcomes) on sexual and physical IPV victimization in a unique sample of 466 young couples from Malawi. Two power resources were studied, namely, income and education level. Power processes were captured with a measure of couple communication and collaboration called unity. Power outcomes included a measure of relationship dominance (male dominated or female-dominated/egalitarian). Multilevel logistic regression using the Actor Partner Interpersonal Model framework was used to test whether respondent and partner data were predictive of IPV. The findings show that unity and male dominance were salient power factors that influenced young people’s risk for sexual IPV. Unity had a stronger protective effect on sexual IPV for women than for men. Involvement in a male-dominated relationship increased the risk of sexual IPV for women, but decreased the risk for men. The findings also showed that education level and unity were protective against physical IPV for both men and women. Contrary to what was expected, partner data did not play a role in the respondent’s experience of IPV. The consistency of these findings with the literature, theory, and study limitations are discussed. PMID:24227592

College men's intimate partner violence attitudes: contributions of adult attachment and gender role stress.

McDermott, Ryon C; Lopez, Frederick G

Primary prevention of men's intimate partner violence (IPV) toward women in dating relationships is an important area of psychological inquiry and a significant concern for counselors working with college student populations. Previous research has identified that certain beliefs condoning or accepting physical, sexual, and psychological violence in relationships are key risk factors for IPV perpetration; however, comparatively few studies have examined the social and relational variables related to IPV acceptance attitudes. In the present study, we proposed and tested a structural model examining the combined contributions of adult attachment dimensions (i.e., attachment anxiety and attachment avoidance) and masculine gender role stress in the prediction of IPV acceptance attitudes in a large sample of college men (N = 419). We hypothesized that the relationship between attachment insecurity and IPV acceptance attitudes would be partially mediated by men's gender role stress. A partially mediated model produced the best indices of model fit, accounting for 31% of the variance in an IPV acceptance attitudes latent variable. A bootstrapping procedure confirmed the significance of mediation effects. These results suggest that aspects of adult attachment insecurity are associated with tendencies to experience stress from violations of rigidly internalized traditional male role norms, which, in turn, are associated with acceptance of IPV. Findings are further discussed in relation to adult attachment theory (Mikulincer & Shaver, 2007), gender role strain theory (Pleck, 1995), and their implications for IPV prevention in college student populations.

Experience of intimate partner violence (IPV) can lead to mental health conditions, including anxiety, depression, and unhealthy substance use. Women seen in the Veterans Health Administration (VHA) face high rates of both IPV and mental health morbidity. This study aimed to identify associations between recent IPV experience and mental health diagnoses among women VHA patients. We examined medical records data for 8,888 female veteran and nonveteran VHA patients across 13 VHA facilities who were screened for past-year IPV between April, 2014 and April, 2016. Compared with women who screened negative for past-year IPV (IPV-), those who screened positive (IPV+; 8.7%) were more than twice as likely to have a mental health diagnosis, adjusted odds ratio (AOR) = 2.27, 95% confidence interval (CI) [1.95, 2.64]; or more than two mental health diagnoses, AOR = 2.29, 95% CI [1.93, 2.72]). Screening IPV+ was also associated with significantly higher odds of each type of mental health morbidity (AOR range = 1.85-3.19) except psychoses. Over half (53.5%) of the women who screened IPV+ had a mental health diagnosis, compared with fewer than one-third (32.6%) of those who screened IPV-. Each subtype of IPV (psychological, physical, and sexual violence) was significantly associated with having a mental health diagnosis (AOR range = 2.25-2.37) or comorbidity (AOR range = 2.17-2.78). Associations remained when adjusting for military sexual trauma and combat trauma among the veteran subsample. These findings highlight the mental health burden associated with past-year IPV among female VHA patients and underscore the need to address psychological and sexual IPV, in addition to physical violence.

This study investigated the long-term effects of exposure to intimate partner violence in the home on adolescent violence and drug use and gender differences in these relationships. Although the general relationship between exposure to IPV and negative outcomes for youth has been demonstrated in past research, gender differences in the effects of IPV on adolescents have been rarely assessed using longitudinal data. Longitudinal data was obtained from 1,315 adolescents and their primary caregivers participating in the Project on Human Development in Chicago Neighborhoods (PHDCN). The sample was 51% female and ethnically diverse (45% Hispanic, 37% African-American, and 14% Caucasian). Two waves of data were assessed to examine the effects of exposure to IPV, reported by caregivers when their children were aged 12 and 15, on violence and drug use, reported by adolescents 3 years later. Multivariate statistical models were employed to control for a range of child, parent, family, and neighborhood risk factors. Exposure to IPV did not significantly predict subsequent violence among males or females in multivariate analyses. IPV exposure was significantly related to the frequency of drug use for females but did not predict drug use among males. This gender difference was not statistically significant, however, which suggests more similarities than differences in the relationship between exposure to IPV and subsequent violence and drug use. This study supports prior research indicating that exposure to IPV can negatively impact adolescent development, but it suggests that these effects may be more likely to influence some outcomes (e.g., drug use) than others (e.g., interpersonal violence). The findings also emphasize the need for additional research examining the overall impact of IPV on adolescent problem behaviors and gender differences in these relationships, including longitudinal studies and investigations that control for a range of other important predictors. A better understanding of these relationships can help inform intervention efforts aimed at ensuring that adolescents living in violent households receive timely and appropriate services to help prevent the occurrence of future problem behaviors.

Intimate Partner Violence, Relationship Power Inequity and the Role of Sexual and Social Risk Factors in the Production of Violence among Young Women Who Have Multiple Sexual Partners in a Peri-Urban Setting in South Africa

Introduction This paper aims to assess the extent and correlates of intimate partner violence (IPV), explore relationship power inequity and the role of sexual and social risk factors in the production of violence among young women aged 16–24 reporting more than one partner in the past three months in a peri-urban setting in the Western Cape, South Africa. Recent estimates suggest that every six hours a woman is killed by an intimate partner in South Africa, making IPV a leading public health problem in the country. While there is mounting evidence that levels of IPV are high in peri-urban settings in South Africa, not much is known about how it manifests among women who engage in concomitantly high HIV risk behaviours such as multiple sexual partnering, transactional sex and age mixing. We know even less about how such women negotiate power and control if exposed to violence in such sexual networks. Methods Two hundred and fifty nine women with multiple sexual partners, residing in a predominantly Black peri-urban community in the Western Cape, South Africa, were recruited into a bio-behavioural survey using Respondent Driven Sampling (RDS). After the survey, focus group discussions and individual interviews were conducted among young women and men to understand the underlying factors informing their risk behaviours and experiences of violence. Findings 86% of the young women experienced IPV in the past 12 months. Sexual IPV was significantly correlated with sex with a man who was 5 years or older than the index female partner (OR 1.7, 95% CI 1.0–3.2) and transactional sex with most recent casual partner (OR 2.1, 95% CI 1.1–3.8). Predictably, women experienced high levels of relationship power inequity. However, they also identified areas in their controlling relationships where they shared decision making power. Discussion Levels of IPV among young women with multiple sexual partners were much higher than what is reported among women in the general population and shown to be associated with sexual risk taking. Interventions targeting IPV need to address sexual risk taking as it heightens vulnerability to violence. PMID:26599394

A Study of Intimate Partner Violence, Substance Abuse, and Sexual Risk Behaviors Among Gay, Bisexual, and Other Men Who Have Sex With Men in a Sample of Geosocial-Networking Smartphone Application Users.

Geosocial-networking smartphone applications ("apps") are widely used by gay, bisexual, and other men who have sex with men (MSM) and facilitate connections between users based on proximity and attraction. MSM have sexual encounters and relationships of varying degrees of emotional and physical intimacy with app-met individuals, potentially placing them at risk for intimate partner violence (IPV). The purpose of the current study was to utilize a geosocial-networking application to investigate relationships between experiences of IPV victimization as it relates to substance use and sexual risk behaviors in a sample of MSM. Participants ( n = 175) were recruited by means of broadcast advertisements on an application widely used by MSM (Grindr) to seek sexual partners. Multivariable regression models were fit to examine associations between IPV, substance abuse, and sexual risk behaviors. Lifetime experiences of IPV victimization were common, where 37.7% of respondents reported having experienced at least one form of IPV. While a marginally significant positive association between IPV and substance abuse was detected in multivariable models ( p = .095), individual forms of IPV were strongly associated with substance abuse. For example, sexual IPV victimization was associated with an increase in substance abuse in the preceding month ( p = .004). Experiences of IPV victimization were associated with higher numbers of partners for both condomless receptive and insertive anal intercourse ( p < .05). Given the relatively high prevalence of IPV victimization and its associations with substance abuse and sexual risk behaviors, these findings suggest that IPV screening and prevention programs may reduce substance abuse and sexual risk behaviors in this population.

Intimate partner and sexual violence screening practices of college health care providers.

Female college students experience higher rates of intimate partner violence (IPV) and sexual violence (SV) compared to men of all ages, older women and young women who are not attending college. Experts and medical organizations have issued recommendations that health care providers should routinely screen women for IPV and SV. However, most female college students report they are not being screened for IPV and SV at college health centers. This exploratory study sought to examine the IPV and SV screening practices of college health care providers and identify individual and organizational influences using a cross-sectional, quantitative survey design. Sixty-four health care providers (physicians, nurse practitioners and registered nurses) from five colleges and universities in the northeastern U.S. were invited to participate in an anonymous, web-based survey about their IPV/SV-related screening practices and beliefs, and organizational characteristics of their college health centers. Twenty-six health care providers completed surveys (56% response rate). The median reported IPV/SV screening rate was 15%. More IPV/SV screening was reported by nurse practitioners, providers at state colleges, and by those in health centers that prioritized IPV/SV screening and had greater organizational capacity for change. College health centers represent unique, yet often missed, opportunities to screen for IPV/SV in a high-risk population. Provider- and organization-level influences should be incorporated into future interventions to improve IPV/SV screening in college health centers. Future studies with larger numbers of colleges and providers are needed to better understand organizational influences and identify mediators and moderators of effects. Copyright © 2017 Elsevier Inc.

To examine correlates of perpetration and victimization of intimate partner violence (IPV) under and not under the influence of a substance, we conducted a study among women in Russia. In 2011, a cross-sectional survey was conducted among patients receiving services at a clinic for sexually transmitted infections in St. Petersburg, Russia. Multinomial logistic regression was used for analysis. Of 299 women, 104 (34.8%) and 113 (37.8%) reported a history of IPV perpetration and victimization, respectively. Nearly half (47.1%) of perpetrators and 61.1% of victims reported that the latest IPV event (perpetration and victimization, respectively) was experienced under the influence of a substance. Factors independently associated with IPV victimization under the influence of a substance were alcohol misuse and a higher number of lifetime sex partners, whereas only experience of childhood abuse (emotional and physical abuse) was independently associated with IPV victimization that did not occur under the influence of a substance. Childhood physical abuse, lower age of first sex, sensation seeking, and alcohol misuse were independently associated with IPV perpetration under the influence of a substance, while only childhood abuse (emotional and physical abuse) was independently associated with IPV perpetration that did not occur under the influence of a substance. IPV under and not under the influence of a substance had different correlates (e.g., alcohol misuse and sensation seeking). Despite the strong association between substance use and IPV, experience of childhood abuse is an important predictor of IPV perpetration and victimization in Russia, above and beyond substance use.

Intimate partner violence (IPV) against women is a complex worldwide public health problem. There is scarce research on the independent effect on IPV exerted by structural factors such as labour and economic policies, economic inequalities and gender inequality. To analyse the association, in Spain, between contextual variables of regional unemployment and income inequality and individual women's likelihood of IPV, independently of the women's characteristics. We conducted multilevel logistic regression to analyse cross-sectional data from the 2011 Spanish Macrosurvey of Gender-based Violence which included 7898 adult women. The first level of analyses was the individual women' characteristics and the second level was the region of residence. Of the survey participants, 12.2% reported lifetime IPV. The region of residence accounted for 3.5% of the total variability in IPV prevalence. We determined a direct association between regional male long-term unemployment and IPV likelihood (P = 0.007) and between the Gini Index for the regional income inequality and IPV likelihood (P < 0.001). Women residing in a region with higher gender-based income discrimination are at a lower likelihood of IPV than those residing in a region with low gender-based income discrimination (odds ratio = 0.64, 95% confidence intervals: 0.55-0.75). Growing regional unemployment rates and income inequalities increase women's likelihood of IPV. In times of economic downturn, like the current one in Spain, this association may translate into an increase in women's vulnerability to IPV. © The Author 2015.

Six different adjuvants, each in combination with inactivated polio vaccine (IPV) produced with attenuated Sabin strains (sIPV), were evaluated for their ability to enhance virus neutralizing antibody titres (VNTs) in the rat potency model. The increase of VNTs was on average 3-, 15-, 24-fold with adjuvants after one immunization (serotypes 1, 2, and 3, respectively). Also after a boost immunization the VNTs of adjuvanted sIPV were on average another 7-20-27 times higher than after two inoculations of sIPV without adjuvant. The results indicate that it is feasible to increase the potency of inactivated polio vaccines by using adjuvants. Copyright © 2013 Elsevier Ltd. All rights reserved.

Prenatal exposure to testosterone interacts with lifetime physical abuse to predict anger rumination and cognitive flexibility among incarcerated methamphetamine users.

Herschl, Laura C; Highland, Krista B; McChargue, Dennis E

2012-01-01

The present pilot study hypothesized that degree of exposure to prenatal testosterone interacts with a history of lifetime physical abuse (LPA) to predict the cognitive (anger rumination) and behavioral (intimate partner and interpersonal violence) components of aggression within incarcerated methamphetamine (MA) users. In addition, we hypothesized that the degree of exposure to prenatal testosterone interacts with LPA to predict cognitive flexibility (Stroop Color-Word performance). Male inmate MA users (N = 60) completed neuropsychological and paper/pencil tests. Hand photocopies were also obtained to index prenatal testosterone exposure. Five covariate-adjusted moderation models were tested using anger rumination, intimate partner violence (IPV) perpetration, interpersonal violence perpetration (before and while incarcerated), and Stroop Color-Word T-score as the criteria, prenatal testosterone exposure as the predictor, and LPA as the moderator. Results indicated that, in individuals with a history of LPA, exposure to higher levels of prenatal testosterone exposure predicted greater anger rumination, lower Stroop Color-Word test T-scores, and lower frequencies of IPV perpetration. Findings were not significant in individuals without a history of LPA. This research suggests that biochemical and psychosocial vulnerabilities influence anger rumination and cognitive flexibility, which may render incarcerated MA users at greater risk to relapse or recidivate upon release from prison.

In a previous study, alcohol problems in perpetrators and their partners contributed directly and indirectly to intimate partner violence (IPV), even after including other correlates of violence in the model (G. L. Stuart et al., 2006). The present study extends these findings by examining the role of illicit drug use. We recruited 271 men and 135 women arrested for IPV and used structural equation modeling to examine the data. Results showed that drug use, as reported by the perpetrators, was a stronger predictor of IPV than were alcohol problems in perpetrators and their partners. Arrested males' marijuana use and stimulant use (i.e., cocaine and amphetamines) were associated with perpetration of IPV, and their report of their female partners' stimulant use was associated with her violence perpetration. In arrested women, specific substances used did not predict violence perpetration beyond other model variables; however, female perpetrators' report of male partners' stimulant use predicted male psychological and physical aggression, after controlling for other variables. These results provide further evidence that drug problems by both partners may be important in the evolution of aggression. Implications for batterer intervention programs are discussed.

Community influences on intimate partner violence in India: Women's education, attitudes towards mistreatment and standards of living.

Intimate partner violence (IPV) directed towards women is a serious public health problem. Women's education may offer protection against IPV, but uncertainty exists over how it might reduce risk for IPV at the community and individual levels. The objectives of this study are to: (1) disentangle community from individual-level influences of women's education on risk for IPV; (2) quantify the moderating influence of communities on individual-level associations between women's education and IPV; (3) determine if women's attitudes towards mistreatment and living standards at the community and individual levels account for the protective influence of women's education; and (4) determine if the protective influence of education against IPV is muted among women living in communities exhibiting attitudes more accepting of mistreatment. Study information came from 68,466 married female participants in the National Family Health Survey conducted throughout India in 1998-1999. Multilevel logistic regression was used to address the study objectives. IPV showed substantial clustering at both the state (10.2%) and community levels (11.5%). At the individual level, there was a strong non-linear association between women's education and IPV, partially accounted for by household living standards. The strength of association between women's education and IPV varied from one community to the next with evidence that the acceptance of mistreatment at the community level mutes the protective influence of higher education. Furthermore, women's attitudes towards mistreatment and their standards of living accounted for community-level associations between women's education and IPV. Place of residence accounted for substantial variation in risk of IPV and also modified individual-level associations between IPV and women's education. At the community level, women's education appeared to exert much of its protective influence by altering population attitudes towards the acceptability of mistreatment. However, there was no residual association between women's education and IPV at the community level once living standards are taken into account. While women's education provides strong, independent leverage for reducing the risk of IPV, planners must keep in mind important community factors that modify its protective influence.

This study investigated the prevalence and impact of childhood sexual abuse (CSA) on future intimate partner violence (IPV) in dating relationship in Hong Kong, China. A total of 1,154 Chinese adult respondents engaged in dating relationships were interviewed face-to-face about their CSA histories, childhood witnessing of parental violence, adult sexual victimization (ASV) by others and IPV victimization with their current dating partner. Self-reports also measured levels of suicidal ideation, self-esteem, and demographic details. Overall, 1.7% reported some form of CSA with a higher percentage being women. No gender differences were found in the prevalence of either ASV or IPV. Results showed that CSA had an independent effect on physical IPV and suicidal ideation. The odds of IPV were increased by behavioral and psychological factors of victims such as alcohol and drug abuse, sex with partner, and low self-esteem. The odds of suicidal ideation were also increased by drug abuse, childhood witnessing of parental psychological aggression, and low self-esteem. Clinical implications of results included screening for CSA victims and suicidal victims when treating IPV patients, tailoring treatment according to individual IPV victim's problems, correcting behaviors that are associated with risks of IPV, such as engagement in casual sex and substance abuse, and focusing not only on tangible services but also on the social and psychological aspects that are placing the victims at risk for IPV.

Research assessing the effectiveness of intervention programs for intimate partner violence (IPV) perpetrators has increased considerably in recent years. However, most of it has been focused on the analysis of psychological domains, neglecting neuropsychological variables and the effects of alcohol consumption on these variables. This study evaluated potential neuropsychological changes (emotional decoding, perspective taking, emotional empathy and cognitive flexibility) and their relationship with alcohol consumption in a mandatory intervention program for IPV perpetrators, as well as how these variables affect the risk of IPV recidivism. The sample was composed of 116 individuals with high alcohol (n = 55; HA) and low alcohol (n = 61; LA) consumption according to self-report screening measures who received treatment in a IPV perpetrator intervention program developed in Valencia (Spain). IPV perpetrators with HA consumption were less accurate in decoding emotional facial signals and adopting others’ perspective, and less cognitively flexible than those with LA consumption before the IPV intervention. Further, the effectiveness of the intervention program was demonstrated, with increases being observed in cognitive empathy (emotional decoding and perspective taking) and in cognitive flexibility. Nevertheless, the HA group showed a smaller improvement in these skills and higher risk of IPV recidivism than the LA group. Moreover, improvement in these skills was related to a lower risk of IPV recidivism. The study provides guidance on the targeting of cognitive domains, which are key factors for reducing IPV recidivism. PMID:27043602

The aim of this study was to examine the impact of sexual intimate partner violence (IPV) on mental health among Japanese women and to explore to what extent sexual IPV is an important contributor to the severity of mental health problems in comparison with physical and psychological IPV. A cross-sectional analysis was conducted of the medical records of participants during psychiatric consultation at the Institute of Women's Health, Tokyo Women's Medical University, including 62 women who experienced IPV without sexual violence and 83 women who experienced IPV with sexual violence. Mental health problems were compared, including anxiety, depression, suicidality, post-traumatic stress disorder (PTSD), and dissociative experiences. The results demonstrated a higher incidence and severity of somatic symptoms, insomnia, social dysfunction, severe depression and suicidality, PTSD, and dissociative experiences among women in the sexual IPV group than in the women who experienced IPV without sexual violence. In analyzing the relative contribution of sexual, physical, and psychological violence to the severity of mental health problems of the survivors, results indicated that sexual violence was an independent predictor of both PTSD and dissociative experiences. The present research showed that significant adverse effects on mental health were observed among women who experienced IPV with sexual violence compared with the ones without. These findings provide important implications for considering the specific approaches to meet the needs of those women experiencing sexual IPV and the need for timely and effective interventions, including healthcare, social services, and primary prevention.

Background: Intimate partner violence (IPV) is associated with higher HIV incidence, reduced condom use, and poor adherence to antiretroviral therapy and other medications. IPV may also affect adherence to pre-exposure prophylaxis (PrEP). Methods: We analyzed data from 1785 HIV-uninfected women enrolled in a clinical trial of PrEP among African HIV serodiscordant couples. Experience of verbal, physical, or economic IPV was assessed at monthly visits by face-to-face interviews. Low PrEP adherence was defined as clinic-based pill count coverage <80% or plasma tenofovir levels <40 ng/mL. The association between IPV and low adherence was analyzed using generalized estimating equations, adjusting for potential confounders. In-depth interview transcripts were examined to explain how IPV could impact adherence. Results: Sixteen percent of women reported IPV during a median of 34.8 months of follow-up (interquartile range 27.0–35.0). Overall, 7% of visits had pill count coverage <80%, and 32% had plasma tenofovir <40 ng/mL. Women reporting IPV in the past 3 months had increased risk of low adherence by pill count (adjusted risk ratio 1.49, 95% confidence interval: 1.17 to 1.89) and by plasma tenofovir (adjusted risk ratio 1.51, 95% confidence interval: 1.06 to 2.15). Verbal, economic, and physical IPV were all associated with low adherence. However, the impact of IPV diminished and was not statistically significant 3 months after the reported exposure. In qualitative interviews, women identified several ways in which IPV affected adherence, including stress and forgetting, leaving home without pills, and partners throwing pills away. Conclusions: Women who reported recent IPV in the Partners PrEP Study were at increased risk of low PrEP adherence. Strategies to mitigate PrEP nonadherence in the context of IPV should be evaluated.

The prevalence of intimate partner violence (IPV), a gross violation of human rights, ranges widely across the world with higher prevalence reported in low- and middle-income countries. Evidence related mainly to physical health shows that IPV has both direct and indirect impacts on women's health. Little is known about the impact of IPV on the mental health of women, particularly after childbirth. To describe the prevalence of IPV experienced by women 6-8 months after childbirth in rural Bangladesh and the factors associated with physical IPV. The study also aims to investigate the association between IPV and maternal depressive symptoms after childbirth. The study used cross-sectional data at 6-8 months postpartum. The sample included 660 mothers of newborn children. IPV was assessed by physical, emotional, and sexual violence. The Edinburgh Postnatal Depression Scale assessed maternal depressive symptoms. Prevalence of physical IPV was 52%, sexual 65%, and emotional 84%. The husband's education (OR: 0.41, CI: 0.23-0.73), a poor relationship with the husband (OR: 2.64, CI: 1.07-6.54), and emotional violence by spouse (OR: 1.58, CI: 1.35-1.83) were significantly associated with physical IPV experienced by women. The perception of a fussy and difficult child (OR: 1.05, CI: 1.02-1.08), a poor relationship with the husband (OR: 4.95, CI: 2.55-9.62), and the experience of physical IPV (OR: 2.83, CI: 1.72-4.64) were found to be significant predictors of maternal depressive symptoms among women 6-8 months after childbirth. Neither forced sex nor emotional violence by an intimate partner was found to be significantly associated with maternal depressive symptoms 6-8 months postpartum. It is important to screen for both IPV and depressive symptoms during pregnancy and postpartum. Since IPV and spousal relationships are the most important predictors of maternal depressive symptoms in this study, couple-focused interventions at the community level are suggested.

Alcohol misuse is associated with increased human immunodeficiency virus sexual risk behaviors by women. Drug use, intimate partner violence (IPV), and depressive symptoms frequently co-occur, are well-recognized alcohol misuse comorbidities, and may interact to increase risk behaviors. Using a syndemic framework we examined associations between drug use, IPV, and depressive symptoms and sexual risk behaviors by 400 women with alcohol misuse attending an urban sexually transmitted infections clinic. Participants completed computer-assisted interviews querying drug use, IPV, and depressive symptoms and sexual risk behavior outcomes-unprotected sex under the influence of alcohol, sex for drugs/money, and number of lifetime sexual partners. We used multivariable analysis to estimate prevalence ratios (PR) for independent and joint associations between drug use, IPV, and depressive symptoms and our outcomes. To investigate synergy between risk factors we calculated the relative excess prevalence owing to interaction for all variable combinations. In multivariable analysis, drug use, IPV, and depressive symptoms alone and in combination were associated with higher prevalence/count of risk behaviors compared with women with alcohol misuse alone. The greatest prevalence/count occurred when all three were present (unprotected sex under the influence of alcohol [PR, 2.6; 95% confidence interval, 1.3-4.9]), sex for money or drugs [PR, 2.6; 95% confidence interval, 1.7-4.2], and number of lifetime partners [PR, 3.2; 95% confidence interval, 1.9-5.2]). Drug use, IPV, and depressive symptoms did not interact synergistically to increase sexual risk behavior prevalence. A higher prevalence of sexual risk behaviors by women with alcohol misuse combined with drug use, IPV, and depressive symptoms supports the need for alcohol interventions addressing these additional comorbidities.

Intimate partner violence (IPV) victimization and perpetration and power imbalances in parenting partners may result in poor outcomes for parents and children. Previous work in this area has focused on the maternal experiences, neglecting to examine paternal effects. The present study aimed to elucidate the role of IPV, power, and equity in parenting and child outcomes in an urban sample of adolescent parents. 159 male and 182 female parents in a relationship were recruited through university-affiliated hospitals. Power, equity, and IPV were measured at 6 months post-partum and were used as predictors for parenting and child outcomes 12 months post-partum using general estimating equations. Gender interactions and mediation effects of depression were also assessed. Higher perceived relationship equity was related to better infant temperament (B = 0.052, SE = 0.023, p = 0.02) whereas higher partner power was related to poorer social development (B = −0.201, SE = 0.088, p = 0.02) and fine motor development (B = −0.195, SE = 0.078, p = 0.01). IPV victimization was associated with poor infant temperament (B = −2.925, SE = 1.083, p = 0.007) and lower parenting competence (B = −3.508, SE = 1.142, p = 0.002). Depression mediated the relationship between IPV and parenting and IPV and infant temperament. No gender effects were found. IPV, inequities, and power imbalances were disadvantageous for parenting and child outcomes. Our results suggest that these dynamics may negatively affect both males and females. Interventions to reduce violence in both partners and promote equity in relationships could benefit couples and their children. PMID:24781878

Women who have experienced interpersonal violence (IPV) are at a higher risk to develop posttraumatic stress disorder (PTSD), with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and impaired social behavior. Previously, we had reported impaired maternal sensitivity and increased difficulty in identifying emotions (i.e. alexithymia) among IPV-PTSD mothers. One of the aims of the present study was to examine maternal IPV-PTSD salivary cortisol levels diurnally and reactive to their child's distress in relation to maternal alexithymia. Given that mother-child interaction during infancy and early childhood has important long-term consequences on the stress response system, toddlers' cortisol levels were assessed during the day and in response to a laboratory stressor. Mothers collected their own and their 12-48month-old toddlers' salivary samples at home three times: 30min after waking up, between 2-3pm and at bedtime. Moreover, mother-child dyads participated in a 120-min laboratory session, consisting of 3 phases: baseline, stress situation (involving mother-child separation and exposure to novelty) and a 60-min regulation phase. Compared to non-PTSD controls, IPV-PTSD mothers - but not their toddlers, had lower morning cortisol and higher bedtime cortisol levels. As expected, IPV-PTSD mothers and their children showed blunted cortisol reactivity to the laboratory stressor. Maternal cortisol levels were negatively correlated to difficulty in identifying emotions. Our data highlights PTSD-IPV-related alterations in the HPA system and its relevance to maternal behavior. Toddlers of IPV-PTSD mothers also showed an altered pattern of cortisol reactivity to stress that potentially may predispose them to later psychological disorders. Copyright © 2017 Elsevier Inc.

2014-01-01

A computerized sign language survey was administered to two large samples of deaf adults. Six questions regarding intimate partner violence (IPV) were included, querying lifetime and past-year experiences of emotional abuse, physical abuse, and forced sex. Comparison data were available from a telephone survey of local households. Deaf respondents reported high rates of emotional abuse and much higher rates of forced sex than general population respondents. Physical abuse rates were comparable between groups. More men than women in both deaf samples reported past-year physical and sexual abuse. Past-year IPV was associated with higher utilization of hospital emergency services. Implications for IPV research, education, and intervention in the Deaf community are discussed. PMID:24142445

Maternal parenting as a mediator of the relationship between intimate partner violence and effortful control.

Gustafsson, Hanna C; Cox, Martha J; Blair, Clancy

2012-02-01

The current study examined the relationship between intimate partner violence (IPV), maternal parenting behaviors, and child effortful control in a diverse sample of 705 families living in predominantly low-income, rural communities. Using structural equation modeling, the authors simultaneously tested whether observed sensitive parenting and/or harsh-intrusive parenting over the toddler years mediated the relationship between early IPV and later effortful control. Results suggest that parenting behaviors fully mediate this relationship. Although higher levels of IPV were associated with both higher levels of harsh-intrusive parenting and lower levels of sensitive supportive parenting, only sensitive supportive parenting was associated with later effortful control when both parenting indices were considered in the same model.

Although intimate partner violence (IPV) during perinatal period is more common than during other maternal health conditions, it receives less attention within research on maternal mortality rates. Given the risks for maternal mortality because of suicidality, the purpose of this investigation is to examine the risk of suicidal ideation (SI) among postpartum women exposed to IPV. In this cross-sectional study, participants were recruited between May 2005 and March 2007 from primary care clinics in São Paulo, Brazil. A total of 701 postpartum women were included in the analysis. Postpartum SI was assessed using the clinical interview schedule-revised. IPV was assessed using a structured questionnaire previously validated in Brazilian populations. Crude and adjusted risk ratios with 95% confidence intervals (95% CI) were estimated using Poisson regression with robust variance to examine the association between IPV and the risk for postpartum SI. The prevalence of postpartum SI was 4%. Among those with postpartum SI, 70% reported IPV during the postpartum period. Compared with non-IPV counterparts, postpartum women who reported IPV had an increased risk for SI (relative risk [RR] 7.25, 95% CI: 3.23-16.27). In the fully adjusted model, the risk for SI remained significantly higher for women who experienced IPV than for those who did not (RR 3.02, 95% CI: 1.29-7.07). Postpartum women exposed to violence had a threefold greater risk of having suicidal thoughts.

As poliovirus eradication draws closer, alternative Inactivated Poliovirus Vaccines (IPV) are needed to overcome the risks associated with continued use of the Oral Poliovirus Vaccine and of neurovirulent strains used during manufacture of conventional (c) IPV. We have previously demonstrated the susceptibility of the PER.C6(®) cell line to cIPV strains; here we investigated the suspension cell culture platform for growth of attenuated poliovirus strains. We examined attenuated Sabin strain productivity on the PER.C6(®) cell platform compared to the conventional Vero cell platform. The suitability of the suspension cell platform for propagation of rationally-attenuated poliovirus strains (stabilized Sabin type 3 S19 derivatives and genetically attenuated and stabilized MonoCre(X) strains), was also assessed. Yields were quantified by infectious titer determination and D-antigen ELISA using either serotype-specific polyclonal rabbit sera for Sabin strains or monoclonal cIPV-strain-specific antibodies for cIPV, S19 and MonoCre(X) strains. PER.C6(®) cells supported the replication of Sabin strains to yields of infectious titers that were in the range of cIPV strains at 32.5°C. Sabin strains achieved 30-fold higher yields (p<0.0001) on the PER.C6(®) cell platform as compared to the Vero cell platform in infectious titer and D-antigen content. Furthermore, Sabin strain productivity on the PER.C6(®) cell platform was maintained at 10l scale. Yields of infectious titers of S19 and MonoCre(X) strains were 0.5-1 log10 lower than seen for cIPV strains, whereas D-antigen yield and productivities in doses/ml using rationally-attenuated strains were in line with yields reported for cIPV strains. Sabin and rationally-attenuated polioviruses can be grown to high infectious titers and D-antigen yields. Sabin strain infection shows increased productivity on the PER.C6(®) cell platform as compared to the conventional Vero cell platform. Novel cell platforms with the potential for higher yields could contribute to increased affordability of a next generation of IPV vaccines needed for achieving and maintaining poliovirus eradication.

Objectives: This study assessed intimate partner violence (IPV) and alcohol use in an urban population in Pune, India. The prevalence of IPV and alcohol use was assessed along with the correlation of IPV with alcohol and other variables. Materials and Methods: The study was cross-sectional, questionnaire-based. The materials used were the hurt insult threaten scream (HITS) scale, the alcohol use disorders identification test, and a brief psychosocial questionnaire. Systematic random sampling was done on the target population. Regression analysis of various factors in relation to HITS score was done. Results: Sample size (n) was 318 individuals. Prevalence of IPV was found to be 16% and the victims were mostly women. Prevalence of alcohol use was 44%, of which 8.9% were harmful users. No female subjects consumed alcohol, but 94% were aware of their husband's alcohol consumption. No significant correlation was found between IPV and education (P = 0.220) or income of women (P = 0.250). Alcohol consumption by males was a significant risk factor for women experiencing IPV (σ = +0.524; P< 0.001). Regression analysis also revealed that increasing marital age (P = 0.019) and financial support from in-laws (P = 0.040) were significantly protective. Conclusion: IPV prevalence was less than the national average for India, but the majority of victims was women. The most common type of IPV was verbal. Alcohol use prevalence was higher than the national average, but harmful use was lower. Alcohol use is a significant risk factor for IPV. Education and income of women were not significantly protective against IPV but increased age at marriage and support from in-laws were. PMID:27212823

Objectives To examine correlates of perpetration and victimization of intimate partner violence (IPV) under and not under the influence of a substance, we conducted a study among women in Russia. Methods In 2011, a cross-sectional survey was conducted among patients receiving services at a clinic for sexually transmitted infections in St. Petersburg, Russia. Multinomial logistic regression was used for analysis. Results Of 299 women, 104 (34.8%) and 113 (37.8%) reported a history of IPV perpetration and victimization, respectively. Nearly half (47.1%) of perpetrators and 61.1% of victims reported that the latest IPV event (perpetration and victimization, respectively) was experienced under the influence of a substance. Factors independently associated with IPV victimization under the influence of a substance were alcohol misuse and a higher number of lifetime sex partners, whereas only experience of childhood abuse (emotional and physical abuse) was independently associated with IPV victimization that did not occur under the influence of a substance. Childhood physical abuse, lower age of first sex, sensation seeking, and alcohol misuse were independently associated with IPV perpetration under the influence of a substance, while only childhood abuse (emotional and physical abuse) was independently associated with IPV perpetration that did not occur under the influence of a substance. Conclusions IPV under and not under the influence of a substance had different correlates (e.g., alcohol misuse and sensation seeking). Despite the strong association between substance use and IPV, experience of childhood abuse is an important predictor of IPV perpetration and victimization in Russia, above and beyond substance use.

There is some limited evidence of an association between maternal intimate partner victimization (IPV) and children's experience of maltreatment. Using data from a longitudinal study, we examine whether this relationship is independent of range of potential confounders including socio-economic, familial and psychological factors. Data were taken from the 14 and 30-year follow-ups of the Mater-University of Queensland Study of Pregnancy (MUSP) in Australia. A subsample of 2064 mothers and children (59.0% female) whose data on maternal IPV and child maltreatment was available, were analysed. In families with maternal IPV, two in five children reported being maltreated, compared to one in five children maltreated in families without maternal IPV. Except for sexual maltreatment which was consistently higher in female offspring, there was no gender differences in experiencing different types of maltreatment in families manifesting maternal IPV. Although both males and females were at increased risk of child maltreatment in families where mothers were victimized by their male partners, male children were more likely to be emotionally maltreated. The main associations were substantially independent of measured confounders, except for father's history of mental health problems which attenuated the association of maternal IPV victimization and male offspring's physical abuse. Our findings confirm that there is a robust association between maternal IPV and child maltreatment. Both maternal IPV victimization and child maltreatment co-occur in a household characterized by conflict and violence. Consequences of IPV go beyond the incident and influence all family members. Efforts to reduce child maltreatment may need to address the greater level of IPV associated with the cycle of family violence. Copyright © 2018 Elsevier Ltd. All rights reserved.

Psychobiology of cumulative trauma: hair cortisol as a risk marker for stress exposure in women.

Morris, Matthew C; Abelson, James L; Mielock, Alyssa S; Rao, Uma

2017-07-01

Childhood trauma (CT) is associated with long-lasting alterations of the hypothalamic-pituitary-adrenal (HPA) axis and elevated risk for stress exposure in adulthood. Although HPA alterations are present in the early aftermath of trauma, it remains unclear how initial HPA activity is associated with subsequent stress exposure and whether CT exposure influences the strength and direction of this association. The present study examined prospective associations between hair cortisol content (HCC) and stress exposure from baseline to 3-month follow-up in young adult women with recent (i.e. past 3 months) exposure to interpersonal violence (IPV; i.e. physical or sexual assault) and non-traumatized controls. History of significant CT abuse or neglect was determined based on clinical cutoffs for a self-report CT measure: 12 women had abuse or neglect and recent IPV exposure (CT + IPV); 7 women had abuse or neglect but no IPV exposure (CT); 15 women had no history of trauma (NTC). HCC was computed for 3 cm sections reflecting cortisol secretion during the 3 months preceding the baseline assessment. The interaction of cumulative trauma and HCC predicted stress exposure over 3-month follow-up, controlling for baseline stress exposure and depressive symptoms. Simple slopes analyses revealed that lower baseline HCC predicted greater stress exposure in the CT + IPV group compared to the CT group; HCC was not associated with stress exposure in the NTC group. The present findings highlight the potential utility of HCC as a predictor of stress exposure for women with a history of childhood abuse or neglect, particularly in the context of recent IPV. Lay summary Adults with a history of CT show long-lasting alterations in major stress response systems, including the HPA axis. They are also more likely to experience stressful life events in adulthood. However, it is not clear how altered HPA activity influences risk for stress exposure and whether CT affects their relationship. The results from this study show that lower HPA activity (measured with hair cortisol) predicted greater stress exposure in women with CT - particularly for women who also experienced recent incidents involving physical or sexual assault.

Research on gender roles suggests that men who strongly adhere to traditional masculine gender norms are at increased risk for the perpetration of violent and abusive acts toward their female intimate partners. Yet, gender norms alone fail to provide a comprehensive explanation of the multifaceted construct of intimate partner violence (IPV) and there is theoretical reason to suspect that men who fail to conform to masculine roles may equally be at risk for IPV. In the present study, we assessed effect of masculine discrepancy stress, a form of distress arising from perceived failure to conform to socially-prescribed masculine gender role norms, on IPV. Six-hundred men completed online surveys assessing their experience of discrepancy stress, masculine gender role norms, and history of IPV. Results indicated that masculine discrepancy stress significantly predicted men’s historical perpetration of IPV independent of other masculinity related variables. Findings are discussed in terms of potential distress engendered by masculine socialization as well as putative implications of gender role discrepancy stress for understanding and intervening in partner violence perpetrated by men.

Objective Considering both the economic crisis of 2008 and the Gender Equality Law (2007), this study analyses the association between gender inequality in Spanish Autonomous Communities (AC) and intimate partner violence (IPV) from 2006 to 2014 in terms of socio-demographic characteristics. Methods Ecological study in the 17 Spanish AC on the correlation between the reported cases by IPV and deaths and the Gender Inequality Index and its dimensions: empowerment, participation in the labour market and adolescent birth rates; and their correlation with Young People Not in Education, Employment or Training (NEET). Results In 2006, IPV mortality rates were higher in autonomous communities with greater gender inequality than AC with more equality (4.1 vs. 2.5 × 106 women >14 years), as were reporting rates of IPV (OR = 1.49; 95% CI: 1.47–1.50). In 2014, the IPV mortality rates in AC with greater gender inequality fell to just below the mortality rates in AC with more gender equality (2.5 vs. 2.7 × 106 women >14 years). Rates of IPV reports also decreased (OR = 1.22; 95% CI: 1.20–1.23). Adolescent birth rates were most associated with IPV reports, which were also associated with the burden of NEET by AC (ρ2006 = 0.494, ρ2014 = 0.615). Conclusion Gender-sensitive policies may serve as a platform for reduced mortality and reports of IPV in Spain, particularly in AC with more gender inequality. A reduction of NEET may reduce adolescent birth rates and in turn IPV rates. PMID:27793548

Examination of maternal experiences of intimate partner violence (IPV) and depression as risk factors for food insecurity can provide a more nuanced understanding of the role that the family environment and women's health plays in the lives of families with young children that experience food insecurity. We investigated the longitudinal association between mothers' experiences of IPV and household food insecurity, and whether maternal depression mediated the relationship. IPV, depression, and food insecurity were assessed among 1,690 socioeconomically disadvantaged mothers of young children who participated in the Fragile Families and Child Wellbeing study. Longitudinal multivariate logistic regression models were used to examine the association between IPV measured 3 years after the child's birth and increase in food insecurity from child's third to fifth birthday, as well as the mediating role of maternal depression, controlling for a number of maternal and household characteristics. Mothers who reside in food insecure households and those who experience IPV share similar characteristics of socioeconomic disadvantage and a greater propensity for depression compared to their counterparts. Mothers' experiences of IPV predicted an increased risk of household food insecurity two years later, and the relationship was mediated by maternal depression. Food insecure mothers may benefit from widespread assistance. Targeting issues central to women's health must become a priority in combating food insecurity. Having IPV and mental health screenings coincide with food assistance applications may help identify women who would benefit from resources designed to increase physical safety, psychological well-being, and food security.

"You can never work with addictions in isolation": Addressing intimate partner violence perpetration by men in substance misuse treatment.

Radcliffe, Polly; Gilchrist, Gail

2016-10-01

Studies have shown rates of IPV-perpetration among men in substance misuse treatment at rates far higher than the general population. There is poor evidence for the effectiveness of IPV perpetrator programmes. An analysis of drugs and alcohol policy documents 1998-2015 was conducted using discourse analysis to examine how English drug and alcohol policy has addressed IPV among substance misusers. Transcripts of interviews with 20 stake holders were analysed thematically. How policy 'frames' IPV-perpetration among drug and alcohol misusers has implications for service provision. IPV has increasingly been framed in terms of its implications for child safeguarding, and has been 'folded in' to policies targeting Troubled Families. With increasing 'localism' in English drug and alcohol policy there has been little specification of services for substance misusing IPV-perpetrators. Policy and literature produced by IPV perpetrator and victim organisations has framed IPV-perpetration as an individual choice with intoxication as a post hoc excuse for violence with limited implications for effective service development. Interviews with stake holders indicate a range of understandings/explanations for IPV among substance misusing men. Stake holders suggest that not all staff have the confidence or skills to ask men about their relationships and that there are few referral routes for substance misusing men who seek help for their IPV perpetration. There are gaps and contradictions in the extent to which English drug and alcohol policy has sought to address IPV-perpetration among substance misusers. Recent National Institute for Health and Care Excellence guidance provide an opportunity to include domestic abuse training for all front line social care staff including in the substance misuse sector. There is a need for further research into effective services for substance misusing perpetrators and the development of training for front-line staff. Copyright © 2016 The Authors.

A systematic review of longitudinal studies suggests that intimate partner violence (IPV) is associated with reduced contraceptive use, but most included studies were limited to two time points. We used seven waves of data from the Rakai Community Cohort Study in Rakai, Uganda to estimate the effect of prior year IPV at one visit on women's current contraceptive use at the following visit. We used inverse probability of treatment-weighted marginal structural models (MSMs) to estimate the relative risk of current contraceptive use comparing women who were exposed to emotional, physical, and/or sexual IPV during the year prior to interview to those who were not. We accounted for time-fixed and time-varying confounders and prior IPV and adjusted standard errors for repeated measures within individuals. The analysis included 7923 women interviewed between 2001 and 2013. In the weighted MSMs, women who experienced any form of prior year IPV were 20% less likely to use condoms at last sex than women who had not (95% CI: 0.12, 0.26). We did not find evidence that IPV affects current use of modern contraception (RR: 0.99; 95% CI: 0.95, 1.03); however, current use of a partner-dependent method was 27% lower among women who reported any form of prior-year IPV compared to women who had not (95% CI: 0.20, 0.33). Women who experienced prior-year IPV were less likely to use condoms and other forms of contraception that required negotiation with their male partners and more likely to use contraception that they could hide from their male partners. Longitudinal studies in Rakai and elsewhere have found that women who experience IPV have a higher rate of HIV than women who do not. Our finding that women who experience IPV are less likely to use condoms may help explain the relation between IPV and HIV. Copyright © 2018 Elsevier Ltd. All rights reserved.

Intimate partner violence (IPV) is a worldwide health concern and an important risk factor for poor mental/physical health in both women and men. Little is known about whether IPV leads to sleep disturbance. However, sleep problems may be common in the context of IPV and may mediate relationships with mental/physical health. Data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS) were used (N = 34,975). IPV was assessed in female and male participants for any history of being threatened by, physically hurt by, or forced to have sex with an intimate partner (THREAT, HURT, and SEX, respectively), and, further, as being forced to have sex with or physically injured by an intimate partner within the past year (SEXyr and HURTyr, respectively). These survey items were coded yes/no. Sleep disturbance was assessed as difficulty falling asleep, staying asleep, or sleeping too much at least 6 of the last 14 days. Logistic regression analyses, adjusted for age, sex, race, income, education, and physical/mental health, assessed whether IPV predicted sleep disturbance. Sobel-Goodman tests assessed whether relationships between IPV and physical/mental health were partially mediated by sleep disturbance. All IPV variables were associated with sleep disturbance, even after adjusting for the effects of age, sex, race/ethnicity, income, education, employment, marital status, physical health and mental health. THREAT was associated with sleep disturbance (odds ratio [OR] = 2.798, p < .0001), as was HURT (OR = 2.683, p < .0001), SEX (OR = 3.237, p < .0001), SEXyr (OR = 7.741, p < .0001), and HURTyr (OR = 7.497, p < .0001). In mediation analyses, all IPV variables were associated with mental health (p < .0001), and all were associated with physical health (p < .007) except SEXyr. Sleep disturbance partially mediated all relationships (Sobel p < .0005 for all tests). Mediation was around 30%, ranging from 18% (HURTyr and mental health) to 41% (HURT and physical health). IPV was strongly associated with current sleep disturbance above the effect of demographics and overall mental/physical health, even if the IPV happened in the past. Furthermore, sleep disturbance partially mediates the relationship between IPV and mental/physical health. Sleep interventions may potentially mitigate negative effects of IPV. © The Author(s) 2015.

Sexual victimization and family violence among urban African American adolescent women: do violence cluster profiles predict partner violence victimization and sex trade exposure?

2012-11-01

Guided by an intersectional feminist perspective, we examined sexual victimization, witnessing intimate partner violence (IPV) in the family, and familial physical abuse among a sample of 180 urban African American adolescent women. We used cluster analysis to better understand the profiles of cumulative victimization, and the relationships between profiles and IPV victimization and personal exposure to the sex trade. Just under one third of the sample reported sexual victimization, with cooccurrence with both forms of family violence common. The cluster profile with high levels of severe family violence was associated with the highest rate of IPV victimization and sex trade exposure.

Intimate Partner Violence and Controlling Behavior Among Male Same-Sex Relationships in China: Relationship With Ambivalent Sexism.

2017-08-01

In this study, we examined intimate partner violence (IPV), cold violence, and controlling behaviors in male same-sex relationships in China, with a focus on the characteristics of IPV and controlling behaviors, and their relationships with ambivalent sexism. IPV was categorized as psychological aggression, physical injury, physical assault, and sexual coercion and was measured using the revised Conflict Tactics Scales (CTS2), an eight-item scale measuring cold violence that was designed specifically for this study. Controlling behaviors were measured using a 34-item scale that was designed for this study, and sexist attitudes toward women and men were assessed using the short forms of the Ambivalent Sexism Inventory (ASI) and the Ambivalence toward Men Inventory (AMI), respectively. Participants ( N = 272) reported instances of perpetration of or victimization by IPV and controlling behaviors within the past 6 months and indicated ambivalent sexism (hostile attitude toward men and women and benevolent attitude toward men and women [HM, HS, BM, and BS, respectively]). Almost 47.1% of the participants reported an experience of IPV, and the prevalence of cold violence and controlling behaviors was found to be 65.1% and 80.5%, respectively. Psychological aggression was the most common, followed sequentially by sexual coercion, physical assault, and injury in present study. We found a strong association between perpetration and victimization and that different forms of violence tend to co-occur in both IPV and controlling behaviors. As predicted, ambivalent sexism was positively correlated with IPV and controlling behaviors, specifically HS and HM. The results indicated the high prevalence of IPV and controlling behaviors among male same-sex relationships, and sexism contributing to this high prevalence.

The objectives of this study were, first, to explore the prevalence of aggressors with lifetime intimate partner violence (IPV) among patients in the Proyecto Hombre of Navarra (Spain) addiction treatment programme; and second, to know the specific and differential characteristics of patients presenting IPV as aggressors. A sample of 162 patients (119 men and 43 women) was assessed. Data on socio-demographic and substance consumption characteristics, IPV variables, psychopathological symptoms, and personality variables were obtained. The profiles of patients in addiction treatment with and without a history of violence towards their partners were compared. The results showed that 33.6% of people in treatment for addiction had committed violence against their partners. This prevalence was significantly higher (χ(2)  = 15.6, p < .001) in women (63.3%) than in men (24.2%). In the 98.4% of the cases the IPV was bidirectional. Patients with a history of IPV perpetration showed greater severity in substance consumption variables, psychopathological symptoms, and personality traits. Gender, the family scale on the European version of the Addiction Severity Index (EuropASI), and the aggressive-sadistic scale on the Millon Clinical Multiaxial Inventory (MCMI-III) were the main variables related to the presence of IPV as aggressors. There was a differential profile in patients with IPV perpetration, showing more psychopathological and personality symptoms. Moreover, in this study being a woman was one of the main predictors of committing IPV. © American Academy of Addiction Psychiatry.

Intimate partner violence (IPV) refers to abuse transpiring between people in an intimate relationship. Intimate partner violence is a leading cause of morbidity and mortality for women that paramedics frequently report encountering and yet paramedics rarely receive formal education or training to manage. The response of paramedics to IPV is likely to be directed by their individual knowledge, attitudes, and preparedness; all of which are currently unknown. This study aimed to measure paramedic students' knowledge, attitudes, and preparedness to manage IPV patients, and provides baseline data to inform the development of contemporary curricula. We surveyed a cohort of paramedic students from two Australian universities using the Modified Physician REadiness to Manage Intimate partner violence Survey (PREMIS). Internal consistency of previously identified scales was calculated and multiple linear regression was used to measure the association between previous training, knowledge, attitudes, and preparation. We received 260 surveys (80.5% response rate). Results show that actual knowledge, perceived knowledge, and preparedness to manage IPV patients were low. Students with previous training reported higher perceived knowledge (p <.05) and preparedness (p <.01). Participants reported low self-efficacy, confidence, and preparation to manage IPV patients and demonstrated mostly neutral attitudes toward women and patients. Results indicate students require increased IPV education. Education should improve knowledge and preparedness to recognize and refer IPV patients, as well as change neutral and inappropriate attitudes. Incorporating such education and training into the paramedic curricula may improve the preparedness of practitioners, resulting in an improved response to IPV patients.

The purpose of the study is to identify the predictors of depression and intimate partner violence (IPV) among Latinos in rural Southeastern North Carolina. A sample of 291 migrant and seasonal farmworkers was interviewed to complete the demographic questionnaire, HITS (intimate violence tendency), Migrant Farmworker Stress Inventory, Center for Epidemiologic Studies Depression Scale (depression), and CAGE/4M (alcohol abuse). OLS regression and structural equation modeling were used to test the hypothesized relations between predictors of IPV and depression. The findings indicated that respondents reporting higher levels of stress also reported higher levels of IPV and depression. The goodness-of-fit statistics for the overall model again indicated a moderate fit of the model to the data (χ2 = 5,612, p < .001; root mean square error for approximation = 0.09; adjusted goodness-of-fit index = 0.44; comparative fit index = 0.52). Although the findings were not robust to estimation in the structural equation models, the OLS regression models indicated direct associations between IPV and depression.

Women's Individual Asset Ownership and Experience of Intimate Partner Violence: Evidence From 28 International Surveys.

2017-05-01

To assess the oft-perceived protective relationship between women's asset ownership and experience of intimate partner violence (IPV) in the previous 12 months. We used international survey data from women aged 15 to 49 years from 28 Demographic and Health Surveys (2010-2014) to examine the association between owning assets and experience of recent IPV, matching on household wealth by using multivariate probit models. Matching methods helped to account for the higher probability that women in wealthier households also have a higher likelihood of owning assets. Asset ownership of any type was negatively associated with IPV in 3 countries, positively associated in 5 countries, and had no significant relationship in 20 countries (P < .10). Disaggregation by asset type, sole or joint ownership, women's age, and community level of women's asset ownership similarly showed no conclusive patterns. Results suggest that the relationship between women's asset ownership and IPV is highly context specific. Additional methodologies and data are needed to identify causality, and to understand how asset ownership differs from other types of women's economic empowerment.

Background Intimate partner violence (IPV), defined as actual or threatened physical, sexual, psychological, and emotional abuse by current or former partners is a global public health concern. The prevalence and determinants of intimate partner violence (IPV) against pregnant women has not been described in Rwanda. A study was conducted to identify variables associated with IPV among Rwandan pregnant women. Methods A convenient sample of 600 pregnant women attending antenatal clinics were administered a questionnaire which included items on demographics, HIV status, IPV, and alcohol use by the male partner. Mean age and proportions of IPV in different groups were assessed. Odds of IPV were estimated using logistic regression analysis. Results Of the 600 respondents, 35.1% reported IPV in the last 12 months. HIV+ pregnant women had higher rates of all forms of IVP violence than HIV- pregnant women: pulling hair (44.3% vs. 20.3%), slapping (32.0% vs. 15.3%), kicking with fists (36.3% vs. 19.7%), throwing to the ground and kicking with feet (23.3% vs. 12.7%), and burning with hot liquid (4.1% vs. 3.5%). HIV positive participants were more than twice likely to report physical IPV than those who were HIV negative (OR = 2.38; 95% CI [1.59, 3.57]). Other factors positively associated with physical IPV included sexual abuse before the age of 14 years (OR = 2.69; 95% CI [1.69, 4.29]), having an alcohol drinking male partner (OR = 4.10; 95% CI [2.48, 6.77] for occasional drinkers and OR = 3.37; 95% CI [2.05, 5.54] for heavy drinkers), and having a male partner with other sexual partners (OR = 1.53; 95% CI [1.15, 2.20]. Education was negatively associated with lifetime IPV. Conclusion We have reported on prevalence of IPV violence among pregnant women attending antenatal care in Rwanda, Central Africa. We advocate that screening for IPV be an integral part of HIV and AIDS care, as well as routine antenatal care. Services for battered women should also be made available. PMID:18847476

Little work has examined the interrelations among intimate partner violence (IPV), alcohol use, and gambling behavior, and no studies have examined these relationships among males court-ordered to batterer intervention programs (BIPs). The aim of the current investigation was to explore the associations between IPV, alcohol use, and gambling behavior among 341 males court-mandated to attend BIPs utilizing self-report measures. Voluntary, anonymous questionnaires were administered and completed during regularly scheduled BIP sessions. Compared to the general population, a higher percentage of the sample met criteria for pathological gambling (9%), and problem gambling (17%). Further, males exhibiting pathological gambling were more likely to be hazardous drinkers, and hazardous drinkers were more likely to exhibit pathological gambling. Additionally, pathological gamblers were at an increased risk for the perpetration of both physical and sexual aggression. Finally, gambling behavior uniquely predicted the perpetration of sexual aggression above and beyond alcohol use, impulsivity, and relationship satisfaction. The implications of these results for future research and intervention are discussed. PMID:21516369

The current study aims to further our understanding of the applicability of the transtheoretical model (TM) to intimate partner violence (IPV), with particular focus on mental health symptoms (depression, posttraumatic stress disorder symptomatology, suicidal ideation) in a sample of low-income African American women seeking medical services at an inner city emergency department. Results revealed that of the 121 abused African American women, the majority (95%) were in the precontempla-tion and contemplation stages of the change process. Further, contrary to predictions, bivariate analyses revealed those at further stages of change endorsed more severe mental health symptoms. However, a multivariate analysis of variance examining differences in level of mental health symptoms between women high and low on stages of change was inconclusive due to the small number of women at the higher stages of the TM model. These findings contribute to the growing body of literature supporting the TM as applied to IPV. Results are discussed in terms of applicability to intervention design. PMID:16897735

Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk-related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.

Objective This study aims to examine the associations between microfinance programme membership and intimate partner violence (IPV) in different socioeconomic strata of a nationally representative sample of women in Bangladesh. Methods The cross-sectional study was based on a nationally representative interview survey of 11 178 ever-married women of reproductive age (15–49 years). A total of 4465 women who answered the IPV-related questions were analysed separately using χ2 tests and Cramer's V as a measure of effect size to identify the differences in proportions of exposure to IPV with regard to microfinance programme membership, and demographic variables and interactions between microfinance programme membership and factors related to non-economic empowerment were considered. Results Only 39% of women were members of microfinance programmes. The prevalence of a history of IPV was 48% for moderate physical violence, 16% for severe physical violence and 16% for sexual violence. For women with secondary or higher education, and women at the two wealthiest levels of the wealth index, microfinance programme membership increased the exposure to IPV two and three times, respectively. The least educated and poorest groups showed no change in exposure to IPV associated with microfinance programmes. The educated women who were more equal with their spouses in their family relationships by participating in decision-making increased their exposure to IPV by membership in microfinance programmes. Conclusions Microfinance plans are associated with an increased exposure to IPV among educated and empowered women in Bangladesh. Microfinance firms should consider providing information about the associations between microfinance and IPV to the women belonging to the risk groups. PMID:24319278

Intimate partner violence (IPV) is a pervasive social concern that may be exacerbated by high rates of alcohol dependence among perpetrators. Society has attempted to combat IPV through various legal interventions but the effects of specific legal factors on behavioral change and treatment compliance remain largely unexamined. The primary focus of the current study was to comprehensively evaluate the impact of various legal factors (i.e., judicial mandate, judicial monitoring, stage of change, and stake in conformity) on mandatory treatment compliance and behavioral change over a 12 week post-adjudication period among a high-risk sample of alcohol dependent IPV offenders (N = 60). Growth curve analyses revealed effects of judicial monitoring and stage of change such that participants reporting low perceived judicial monitoring and early stages of change reported higher initial levels and a more rapid reduction in IPV than those reporting high perceived judicial monitoring and late stages of change, who reported consistently low IPV. Although we found that legal factors were poor predictors of treatment compliance and alcohol use during treatment, the association between alcohol and IPV was moderated by the legal factors. Stake in conformity was negatively associated with IPV among low alcohol users and positively associated among high alcohol users whereas stage of change was negatively associated with IPV among high alcohol users. The current results suggest that pretreatment legal factors may represent an important consideration in reducing IPV among alcohol dependent offenders. Further research is required to determine the efficacy of legal factors in isolation of treatment as well as methods of manipulating these factors to optimally compliment a prescribed course of treatment.

2010-06-01

Few studies have examined adolescent victims of intimate partner violence (IPV) whose victimization is reported to the police or the nature of the incidents that led to the police call. This oversight is problematic for healthcare providers, given that overlap between the use of healthcare and police services is high among IPV victims. We assessed the frequency and nature of police-documented incidents of IPV by men against female adolescents aged 15-17 compared with those against young women aged 18-22. A systematic case ascertainment strategy was applied to administrative data from the Compstat database of a large U.S. metropolitan police department to identify IPV incidents with victims <23 years old. We created additional variables from incident narratives and conducted descriptive analyses on the identified cases. During January-September 2005, police filed reports on 1607 incidents of IPV against women <23 years old: one tenth were younger than 18. Although their risk of police-documented IPV was lower, adolescents' experiences of IPV were remarkably similar to those of 18-22-year-olds. As with adult victims, most assaults against adolescents were through bodily force (94.4%) and occurred in a private residence (75.0%). A substantial minority of adolescents were in adultlike relationships: 9.0% were married, 31.3% were cohabiting, and 20.2% had a child in common. A higher proportion of adolescents, however, experienced an aggravated (vs. simple) assault (11.1%) and sustained visible injuries (12.1%). The commonalities between adolescent and young women's experiences of IPV regarding the nature of the assault, observed injuries, and relationship to assailants have important implications for policy and practice. Findings suggest that routine screening for IPV should begin in adolescence to help prevent future abuse and injury.

Considering both the economic crisis of 2008 and the Gender Equality Law (2007), this study analyses the association between gender inequality in Spanish Autonomous Communities (AC) and intimate partner violence (IPV) from 2006 to 2014 in terms of socio-demographic characteristics. Ecological study in the 17 Spanish AC on the correlation between the reported cases by IPV and deaths and the Gender Inequality Index and its dimensions: empowerment, participation in the labour market and adolescent birth rates; and their correlation with Young People Not in Education, Employment or Training (NEET). In 2006, IPV mortality rates were higher in autonomous communities with greater gender inequality than AC with more equality (4.1 vs. 2.5×10 6 women >14 years), as were reporting rates of IPV (OR=1.49; 95% CI: 1.47-1.50). In 2014, the IPV mortality rates in AC with greater gender inequality fell to just below the mortality rates in AC with more gender equality (2.5 vs. 2.7×10 6 women >14 years). Rates of IPV reports also decreased (OR=1.22; 95% CI: 1.20-1.23). Adolescent birth rates were most associated with IPV reports, which were also associated with the burden of NEET by AC (ρ 2006 =0.494, ρ 2014 =0.615). Gender-sensitive policies may serve as a platform for reduced mortality and reports of IPV in Spain, particularly in AC with more gender inequality. A reduction of NEET may reduce adolescent birth rates and in turn IPV rates. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

Although peer networks have been implicated as influential in a range of adolescent behaviors, little is known about relationships between peer network structures and risk for intimate partner violence (IPV) among youth. This study is a descriptive analysis of how peer network “types” may be related to subsequent risk for IPV perpetration among adolescents using data from 3,030 male respondents to the National Longitudinal Study of Adolescent Health. Sampled youth were a mean of 16 years of age when surveyed about the nature of their peer networks, and 21.9 when asked to report about IPV perpetration in their adolescent and early adulthood relationships. A latent class analysis of the size, structure, gender composition and delinquency level of friendship groups identified four unique profiles of peer network structures. Men in the group type characterized by small, dense, mostly male peer networks with higher levels of delinquent behavior reported higher rates of subsequent IPV perpetration than men whose adolescent network type was characterized by large, loosely connected groups of less delinquent male and female friends. Other factors known to be antecedents and correlates of IPV perpetration varied in their distribution across the peer group types, suggesting that different configurations of risk for relationship aggression can be found across peer networks. Implications for prevention programming and future research are addressed. PMID:20422351

This study investigated criminological, psychopathological, and victimological profiles of intimate partner violence (IPV) perpetrators in a sample of 119 Dutch female and male forensic psychiatric outpatients aged 18 to 58 years. In addition, differences in criminological, psychopathological, and victimological factors between IPV perpetrators (n = 61, 51.3%) and non-intimate violence (NIV) perpetrators (n = 58, 48.7%) were examined. All data, including information on demographics, criminal history, history of psychological, sexual, and physical victimization during childhood or adolescence, family history of psychopathology, history of psychopathology in childhood and adolescence, and mental disorders, were derived from archival electronic medical records. Mental disorders were measured using structured psychiatric interviews and final consensus diagnoses were established during weekly case consultations. Both IPV and NIV perpetrators displayed high rates of criminal history, psychopathology, and previous victimization, but the two groups did not differ in these factors with two exceptions. IPV perpetrators were significantly more likely to have higher rates of previous physical victimization and intermittent explosive disorder than NIV perpetrators. The current study suggests that a history of physical victimization and intermittent explosive disorder are specific characteristics of IPV perpetrators in a forensic psychiatric outpatient setting. Future research should focus on mechanisms explaining the association of childhood victimization and IPV and increase our understanding of the role of intermittent explosive disorder in IPV. © The Author(s) 2014.

The aim of the present study was threefold: (1) learn more about factors associated with teenage intimate partner violence (IPV) victimization; (2) explore aspects of digital media use in connection with teenage IPV; (3) and compare the impact IPV victimization has on boys and girls. Survey data from 549 Norwegian students, mean age 15.2 years, who had experience(s) with being in intimate relationship(s), were examined. Experiences with psychological, physical, digital, and sexual violence were analyzed. In total, 42.9% of the participants had experienced some form of IPV: 29.1% had experienced digital violence; 25.9% had experienced psychological violence; 18.8% had experienced sexual violence; and 12.8% had experienced physical violence. Factors significantly associated with teenage IPV victimization were female gender, older partners, domestic violence, bullying victimization, low academic achievements, and sending sexual messages via digital media. Girls reported to be significantly more negatively impacted by the victimization than boys. CONCLUSIONS SOME TEENAGERS EXPERIENCE VICTIMIZATION IN THEIR INTIMATE RELATIONSHIPS, AND FOR MANY DIGITAL MEDIA SEEMS TO PLAY A CENTRAL ROLE IN THIS VIOLENCE TEENAGERS WHO EXPERIENCE VICTIMIZATION OUTSIDE THEIR RELATIONSHIPS OR HAVE RISKY LIFESTYLES HAVE A HIGHER RISK OF EXPERIENCING IPV VICTIMIZATION A FOCUS ON TEENAGE IPV, AND ESPECIALLY DIGITAL MEDIA'S ROLE IN THIS VIOLENCE, IS NEEDED IF THIS PUBLIC HEALTH ISSUE IS TO BE COMBATED. © 2016 the Nordic Societies of Public Health.

The IPV-GBM scale: a new scale to measure intimate partner violence among gay and bisexual men.

The paper describes the creation of a new scale to measure intimate partner violence (IPV) among gay and bisexual men. Seven focus group discussions were held with gay and bisexual men, focusing on defining intimate partner violence: 30 forms of IPV were identified. A venue-recruited sample of 912 gay and bisexual men was surveyed, examining definitional understanding and recent experiences of each of the 30 forms of IPV. Participants were also asked questions from the CDC definition of intimate partner violence and the short-form of the Conflicts Tactics Scale (CTS2S). Factor analysis of responses to the definitional questions was used to create the IPV-GBM scale, and the prevalence of intimate partner violence was compared with that identified by the CDC and CTS2S measures of intimate partner violence. A 23-item scale, with 5 unique domains, was created, with strong internal reliability (Cronbach Alpha >.90). The IPV-GBM scale mirrored both the CDC and CTS2S definitions of intimate partner violence, but contained additional domains such as controlling violence, monitoring behaviors, emotional violence, and HIV-related violence. The new scale identified a significantly higher prevalence of IPV than either of the more commonly used measures. The results presented here provide encouraging evidence for a new, more accurate measure of intimate partner violence among gay and bisexual men in the U.S.

Tacrolimus (TAC) is the cornerstone of immunosuppressive regimen in liver transplantation (LT). Its pharmacokinetics is characterized by a high interpatient and intrapatient variability (IPV) leading to an unpredictable dose-response relationship. The aim of our study was to evaluate the impact of TAC IPV (IPV) on graft and patient outcomes after LT. We retrospectively analyzed 812 LT recipients treated with TAC. The IPV of TAC concentrations was estimated by calculating the coefficient of variation (CV) of whole blood trough concentrations. Patients were categorized in 2 groups: low IPV (CV < 40%) and high IPV (CV ≥ 40%). There were significantly more neurologic complications (31.2% vs 16.6%, P < 0.001), cardiovascular complications (19.7% vs 9.7%, P < 0.001), and acute renal failure requiring dialysis (8.5% vs 2.2%, P < 0.001) in the high CV group than in the low CV group. Moreover, graft survival was significantly poorer in the high CV group (hazard ratio, 1.42; 95% confidence interval, 1.04-1.95; P = 0.03). A pretransplantation elevated Model for End-Stage Liver Disease score (P < 0.001) and Child-Pugh grade (P < 0.001) were identified as risk factors for presenting a high CV. A high CV of TAC concentrations was found to be predictive of TAC-related toxicity and poorer survival.

The adverse effects of intimate partner violence (IPV) on mental health are well-established, except in the cases of psychological abuse and men's victimization. This research study examines the prevalence and the independent contribution of psychological IPV on mental health for both genders. The initial sample comprises 661 college students from a Portuguese public university, who completed an e-survey. Statistical analysis focused on a subsample (n=364), 23% of which were men, after removing cases of physical and/or sexual abuse. A total of 75% of men and 72% of women reported lifetime psychological victimization and no differences were found for sociodemographic factors, including gender. However, women reported significantly more instigations of psychological abusive acts (OR =5.41, 95% CI=1.88-15.55). Multivariate linear regression models revealed that post-traumatic stress symptoms-PTSS (β=.51; p<.001), depression (β=.34; p<.001) and anxiety (β=.22; p<.001)-were predicted by psychological IPV. The strongest relationship was established between psychological IPV and PTSS, and the final model accounts for 28.6% of the variance (F(6357)=23.86, p<.001). This article provides an empirical basis to recognize the unique and serious impact of psychological IPV on mental health, and recommends screening psychological IPV as part of the clinical routine, developing a gender-inclusive approach, and implementing evidence-based protocols tailored to the needs of these victims.

Five studies tested the hypothesis that self-regulatory failure is an important predictor of intimate partner violence (IPV) perpetration. Study 1 participants were far more likely to experience a violent impulse during conflictual interaction with their romantic partner than they were to enact a violent behavior, suggesting that self-regulatory processes help individuals refrain from perpetrating IPV when they experience a violent impulse. Study 2 participants high in dispositional self-control were less likely to perpetrate IPV, in both cross-sectional and residualized-lagged analyses, than were participants low in dispositional self-control. Study 3 participants verbalized more IPV-related cognitions if they responded immediately to partner provocations than if they responded after a 10-s delay. Study 4 participants whose self-regulatory resources were experimentally depleted were more violent in response to partner provocation (but not when unprovoked) than were nondepleted participants. Finally, Study 5 participants whose self-regulatory resources were experimentally bolstered via a 2-week training regimen exhibited less violent inclinations than did participants whose self-regulatory resources had not been bolstered. These findings hint at the power of incorporating self-regulation dynamics into predictive models of IPV perpetration. (c) 2009 APA, all rights reserved).

S-curve networks and an approximate method for estimating degree distributions of complex networks

Guo, Jin-Li

2010-12-01

In the study of complex networks almost all theoretical models have the property of infinite growth, but the size of actual networks is finite. According to statistics from the China Internet IPv4 (Internet Protocol version 4) addresses, this paper proposes a forecasting model by using S curve (logistic curve). The growing trend of IPv4 addresses in China is forecasted. There are some reference values for optimizing the distribution of IPv4 address resource and the development of IPv6. Based on the laws of IPv4 growth, that is, the bulk growth and the finitely growing limit, it proposes a finite network model with a bulk growth. The model is said to be an S-curve network. Analysis demonstrates that the analytic method based on uniform distributions (i.e., Barabási-Albert method) is not suitable for the network. It develops an approximate method to predict the growth dynamics of the individual nodes, and uses this to calculate analytically the degree distribution and the scaling exponents. The analytical result agrees with the simulation well, obeying an approximately power-law form. This method can overcome a shortcoming of Barabási-Albert method commonly used in current network research.

Studies have shown strong associations between intimate partner violence (IPV) and both posttraumatic stress disorder (PTSD) and substance use disorders (SUD). Despite these linkages, research on the dual diagnosis of PTSD-SUD and its relationship to IPV is in an early stage, and little is known about how PTSD-SUD treatment might influence IPV outcomes. The current study is a secondary analysis of a larger NIDA Clinical Trials Network study exploring the effectiveness of two behavioral interventions for women with comorbid PTSD-SUD. Participants (n=288) were randomly assigned to Seeking Safety (SS), a cognitive-behavioral treatment that focuses on trauma and substance abuse symptoms, or to Women's Health Education, a psychoeducational group. Logistic regressions were used to examine how treatment condition, identified risk factors and their interactions were related to IPV. Results showed that participants who were abstinent at baseline were significantly less likely to experience IPV over the 12-month follow-up period, whereas participants living with someone with an alcohol problem were significantly more likely to experience IPV over follow-up. Findings also showed that at a trend level participants with recent interpersonal trauma at baseline and higher total of lifetime trauma exposures were more likely to report IPV during follow-up. Although there was no main effect for treatment condition, a significant interaction between treatment condition and baseline abstinence was found. Participants who were abstinent at baseline and in the SS condition were significantly less likely to report IPV over follow-up. These findings indicate that an integrated treatment for PTSD and SUD was associated with significantly better IPV outcomes for a subset of individuals. The possibility that women with PTSD-SUD may differentially benefit from SS has important clinical implications. Further research examining the intersection of PTSD, SUD and IPV, and the impact of treatment on a range of outcomes is needed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Studies document a significant association between victimization from intimate partner violence (IPV) and sexually transmitted infections (STIs) and HIV among substance using women in Russia and elsewhere, but no study has examined IPV perpetration and STI among Russian men or HIV-infected men in Eastern Europe. This study was designed to assess the association between lifetime history of IPV perpetration and STI (lifetime and current) among substance using HIV-infected men in Russia. Cross-sectional analyses were conducted with baseline data from 415 male participants enrolled in a randomized HIV intervention clinical trial [the HERMITAGE Study]. Participants were HIV-infected men reporting recent heavy alcohol use and unprotected sex in St. Petersburg, Russia. Baseline surveys assessed demographics, IPV perpetration, risk behaviors, and STI history. Current STI was assessed via blood testing for syphilis and urine testing for gonorrhea, Chlamydia and Trichomonas. Multiple logistic regression analyses were used to assess the association between history of IPV with lifetime and current STI. Participants were aged 20-57 years. Almost half of participants (46%) reported a history of IPV perpetration; 81% reported past 30-day binge alcohol use, and 43% reported past 30-day injection drug use. Past and current STI was 41% and 12%, respectively. Men reporting a history of IPV perpetration had significantly higher odds of reporting ever having an STI (AOR=1.6, 95% CI=1.1, 2.4) but lower odds of testing positive for a current STI (AOR=0.50, 95% CI=0.26, 0.96). These findings demonstrate that a history of male IPV perpetration is common in HIV-infected Russian men and associated with a history of STI. Programmatic work toward IPV prevention is needed in Russia and may be beneficial in mitigating STIs, but more research is needed to understand how and why the association between IPV and STI changes over time in this population.

Readiness to Change as a Predictor of Treatment Engagement and Outcome for Partner Violent Men.

Resistance to change has been long recognized as a barrier to successful intervention for partner violent individuals. Using archival data from a community-based intimate partner violence (IPV) intervention program, the current study investigated readiness to change as a predictor of treatment engagement and outcome in cognitive behavioral therapy (CBT) for IPV, and examined whether court referral status, antisocial personality characteristics, and borderline personality characteristics moderate these associations. During program intake, male IPV perpetrators ( N = 195) provided structured interview data on demographics and referral source, and self-report data on readiness to change, borderline personality traits, and antisocial personality traits. During group CBT, participants and their therapists completed measures of the working alliance, and the therapists completed ratings of compliance with behavior change homework assignments. Criminal recidivism data were gathered from public records for 2 years after scheduled completion of treatment. Readiness to change significantly predicted client ratings of the working alliance, but not therapist ratings of the working alliance, CBT homework compliance, or criminal recidivism. Court referral status moderated predictive associations between readiness to change and working alliance ratings, and borderline and antisocial characteristics moderated predictive associations between readiness to change and working alliance as well as criminal recidivism. Interestingly, readiness to change is a stronger predictor of positive treatment response for court- versus self-referred individuals and for those with either very low or very high levels of borderline and antisocial characteristics. Hence, strategies to enhance motivation to change may be particularly be important for IPV perpetrators with these characteristics.

The impact of inactivated polio vaccines (IPVs) on intestinal mucosal immune responses to live poliovirus is poorly understood. In a 2014 phase 2 clinical trial, Panamanian infants were immunized at 6, 10, and 14 weeks of age with bivalent oral polio vaccine (bOPV) and randomized to receive either a novel monovalent high-dose type 2-specific IPV (mIPV2HD) or a standard trivalent IPV at 14 weeks. Infants were challenged at 18 weeks with a monovalent type 2 oral polio vaccine (mOPV2). Infants' intestinal immune responses during the 3 weeks following challenge were investigated by measuring poliovirus type-specific neutralization and immunoglobulin (Ig) A, IgA1, IgA2, IgD, IgG, and IgM antibodies in stool samples. Despite mIPV2HD's 4-fold higher type 2 polio D-antigen content and heightened serum neutralization profile, mIPV2HD-immunized infants' intestinal immune responses to mOPV2 challenge were largely indistinguishable from those receiving standard IPV. Mucosal responses were tightly linked to evidence of active infection and, in the 79% of participants who shed virus, robust type 2-specific IgA responses and stool neutralization were observed by 2 weeks after challenge. Enhancing IPV-induced serum neutralization does not substantively improve intestinal mucosal immune responses or limit viral shedding on mOPV2 challenge. NCT02111135. © The Author(s) 2018.

Intimate partner violence (IPV) has been recognised as a major obstacle to the achievement of gender equality and human development. Its adverse physical and mental health consequences have been reported to affect women of all ages and backgrounds. Although Indigenous women seem to experience higher rates of partner abuse than non-Indigenous women, mental health consequences of IPV among this population are not yet clearly established in the literature. This study systematically reviewed the global literature on mental health outcomes and risk factors for mental ill health among Indigenous women who experienced IPV. Primary quantitative and mixed methods studies that reported about mental health and IPV among Indigenous women (aged 14+) were included. 21 bibliographic databases were searched until January 2017. Quality of included studies was assessed through the Newcastle-Ottawa Scale. Findings are reported according to PRISMA-P 2015. 13 studies were identified. The majority of studies reported very high rates of IPV and high prevalence of mental disorders. The most frequently identified types of IPV were physical and/or sexual violence, verbal aggression, and emotional abuse. The strongest predictor of poor mental health was physical violence. The most commonly reported mental health outcomes were depression and posttraumatic stress disorder. Despite the small number of studies identified, the available evidence suggests that experiences of IPV and mental disorders among Indigenous women are linked and exacerbated by poverty, discrimination, and substance abuse. More research is needed to better understand distributions and presentations of IPV-related mental illness in this population.

Intimate partner violence (IPV) is a public health concern, affecting one-third of US women. Prior research suggests an association between exposure to IPV and poor maternal perinatal health, but the underlying biological correlates are not well understood. This study examined the relationship between exposure to IPV and proinflammatory cytokine levels, a candidate mechanism accounting for poor psychiatric and obstetric outcomes, across the perinatal period. Data were obtained from a prospective, longitudinal cohort study of 171 women receiving obstetrical care from a hospital-based practice serving a predominantly low-income minority population. Participants completed questionnaires on IPV exposure, psychiatric symptoms, and psychosocial and obstetric factors and provided blood samples at 18 and 32 weeks of gestation and 6 weeks and 6 months postpartum. Serum levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were assayed via enzyme-linked immunosorbent assay. Thirty-five (20.5%) women reported lifetime exposure to IPV and 7 (4.1%) reported being physically hurt in the preceding 12 months (4 while pregnant). Lifetime exposure to IPV was associated with increased likelihood of experiencing perinatal depression and smoking during pregnancy. Women with a history of IPV had significantly higher levels of TNF-α at 18 weeks (z = -2.29, p < 0.05), but significantly smaller changes in levels of IL-6 (β = -0.36, p = 0.04) across time. Lifetime exposure to IPV was associated with a range of adverse mental health outcomes and may affect proinflammatory cytokine levels in pregnancy.

Intimate Partner Violence (IPV) has serious negative health effects to millions of women around the globe. While disclosing IPV could open doors for support and eventually prevent partner abuse, the factors associated with IPV disclosure during pregnancy are not well known. The aim of this study was to examine factors influencing IPV disclosure to any person of interest or organization supporting women during pregnancy in Moshi Municipality, Tanzania. Data were from a prospective cohort study of 1123 pregnant women followed-up by the project aiming to assess the impact of violence in the reproductive health conducted in Moshi Municipality, Tanzania from March 2014 to May 2015. Inclusion criteria to the current analysis were all 339 pregnant women who reported to have experienced physical, sexual and/or emotional violence during the index pregnancy. Data analysis used SPSS Version 20. Odds ratio with 95 % Confidence Interval (CI) for factors associated with IPV disclosure was estimated using multivariate logistic regression models while controlling for age, education and parity. A p-value of less than 0.05 was considered for a statistically significant difference. IPV disclosure was found to be 23.3 % (n = 79). Disclosure of IPV was less likely among unemployed (OR = 0.5, 95 % CI 0.30-0.90) and women whose index pregnancy was unplanned (OR = 0.53, 95 % CI 0.29-0.98). Women who regularly participated in women's or community groups, religious groups or political associations at least once a month had 2 times higher odds of IPV disclosure compared to those who did not attend regularly (OR = 2.12, 95 % CI 1.13-3.95). Most of the abused women during pregnancy who disclosed their experience of IPV (69 %) disclosed to a member of the family of birth followed by friends (14 %) and a member of family of the partner (11 %). Most of the women who experienced IPV during pregnancy kept suffering in silence while less than a quarter of all the abused (23.3 %) disclosed their experience to someone. Identification of the women experiencing IPV during pregnancy should be done as a starting point for supporting victim of IPV. Women empowerment in economical and reproductive health will reduce their vulnerability and facilitate disclosure of IPV for support. Key individuals who informally support victims of IPV should be targeted in interventions.

Evidence suggests that hallucinogens may have therapeutic potential for addressing a variety of problem behaviors related to the externalizing spectrum of psychopathology, such as substance misuse and criminality. Intimate partner violence (IPV) is a prevalent form of criminal violence that is related to externalizing pathology. However, the association between hallucinogen use and IPV has not been comprehensively examined. In this prospective study, we examined the association between IPV and naturalistic hallucinogen use among 302 inmates at a US county jail. Cox regression analyses indicated that hallucinogen use predicted reduced arrest for IPV independently (β=-0.54, SE=0.20, χ(2)=7.19, exp(B)=0.58, p<0.01) and after accounting for covariates (β=-0.48, SE=0.23, χ(2)=4.44, exp(B)=0.62, p<0.05). These results add to a growing literature suggesting distinct therapeutic potential for hallucinogens to assist in the attenuation of problematic behavior. © The Author(s) 2016.

Intimate partner violence (IPV) has been shown to be associated with higher rates of HIV infection among women, underscoring the importance of encouraging IPV victims to receive HIV testing. However, we do not know how much HIV testing behavior is influenced by IPV victimization. The current study characterized the association between individual types of IPV and HIV testing in a large sample of non-pregnant women in 15 US states/territories. The 2005 Behavioral Risk Factor Surveillance System data were analyzed after restricting the sample to non-pregnant women. The dependent variable, whether a woman ever had an HIV test, was examined in relation to individual types of IPV victimization (threatened physical violence; attempted physical violence; completed physical violence; and unwanted sex). Associations between HIV testing and types of IPV were assessed using adjusted risk ratios (aRR) that controlled for demographics and HIV-related risk factors (intravenous drug use, sexually transmitted diseases, exchange sex, unprotected anal sex). Approximately 28.6 % of women reported ever having experienced IPV, and 52.8 % of these women reported being tested for HIV. Among women who had not experienced IPV, 32.9 % reported ever having been tested for HIV. HIV testing was associated with lifetime experience of threatened violence (aRR = 1.43; 95 % CI = 1.24-1.65), attempted violence (aRR = 1.43; 95 % CI = 1.20-1.69), completed physical violence (aRR = 1.30; 95 % CI = 1.13-1.48), and unwanted sex (aRR = 1.66; 95 % CI = 1.48-1.86). Women who experienced each type of IPV were more likely to have been ever tested for HIV compared to women with no IPV history. However, nearly half of those reporting IPV, even though at greater risk for HIV infection, had never been tested. Additional efforts are needed to address barriers to testing in this group.

The role of socioeconomic status in helpseeking from hotlines, shelters, and police among a national sample of women experiencing intimate partner violence.

The role of socioeconomic status (SES) in the prevalence and course of intimate partner violence (IPV) has been established, but mechanisms of this role are less clear. An untested assumption has been that women of greater resources are better able to seek help. This study used a national sample of 1,077 women who had experienced IPV to explore the role of income and education in helpseeking from hotlines, shelters, and police. The authors found that SES did not play a large role in the use of hotlines, the least often used service in this study. Women with more income were less likely to use shelters and were less likely to feel they should have used them. There was an interaction between income and severity of violence in predicting police use, such that severity of violence only predicted calling police among higher income women. This finding suggests the possibility of a lower threshold for reporting violence among the lowest income women. The authors discuss the need for research using a more diverse sample of women, and the need to fine tune services according to our emerging understanding of social context.

Intimate partner violence against women in Maputo city, Mozambique

PubMed Central

2012-01-01

Background There is limited research about IPV against women and associated factors in Sub-Saharan Africa, not least Mozambique. The objective of this study was to examine the occurrence, severity, chronicity and “predictors” of IPV against women in Maputo City (Mozambique). Methods Data were collected during a 12 month-period (consecutive cases, with each woman seen only once) from 1,442 women aged 15–49 years old seeking help for abuse by an intimate partner at the Forensic Services at the Maputo Central Hospital, Maputo City, Mozambique. Interviews were conducted by trained female interviewers, and data collected included demographics and lifestyle variables, violence (using the previously validated Revised Conflict Tactics Scale (CTS2), and control (using the Controlling Behaviour Scale Revised (CBS-R). The data were analysed using bivariate and multivariate methods. Results The overall experienced IPV during the past 12 months across severity (one or more types, minor and severe) was 70.2% (chronicity, 85.8 ± 120.9).a Severe IPV varied between 26.3-45.9% and chronicity between 3.1 ± 9.1-12.8 ± 26.9, depending on IPV type. Severity and chronicity figures were higher in psychological aggression than in the other IPV types. Further, 26.8% (chronicity, 55.3 ± 117.6) of women experienced all IPV types across severity. The experience of other composite IPV types across severity (4 combinations of 3 types of IPV) varied between 27.1-42.6% and chronicity between 35.7 ± 80.3-64.9 ± 110.9, depending on the type of combination. The combination psychological aggression, physical assault and sexual coercion had the highest figures compared with the other combinations. The multiple regressions showed that controlling behaviours, own perpetration and co-occurring victimization were more important in “explaining” the experience of IPV than other variables (e.g. abuse as a child). Conclusions In our study, controlling behaviours over/by partner, own perpetration, co-occurring victimization and childhood abuse were more important factors in “explaining” sustained IPV. More investigation into women’s IPV exposure and its “predictors” is warranted in Sub-Saharan Africa, particularly Mozambique. PMID:23241146

Objectives. To assess the oft-perceived protective relationship between women’s asset ownership and experience of intimate partner violence (IPV) in the previous 12 months. Methods. We used international survey data from women aged 15 to 49 years from 28 Demographic and Health Surveys (2010–2014) to examine the association between owning assets and experience of recent IPV, matching on household wealth by using multivariate probit models. Matching methods helped to account for the higher probability that women in wealthier households also have a higher likelihood of owning assets. Results. Asset ownership of any type was negatively associated with IPV in 3 countries, positively associated in 5 countries, and had no significant relationship in 20 countries (P < .10). Disaggregation by asset type, sole or joint ownership, women’s age, and community level of women’s asset ownership similarly showed no conclusive patterns. Conclusions. Results suggest that the relationship between women’s asset ownership and IPV is highly context specific. Additional methodologies and data are needed to identify causality, and to understand how asset ownership differs from other types of women’s economic empowerment. PMID:28398779

Exploring risk factors associated with intimate partner violence in Vietnam: results from a cross-sectional national survey.

Empirical evidence documents that some risk factors for intimate partner violence (IPV) are similar across contexts, while others differ considerably. In Vietnam, there was a need to investigate risk factors for IPV to support evidence-based policy and programming. Using the dataset gathered in the 2010 National Study on Domestic Violence against Women, forty variables were explored in logistic regression analysis, including socio-demographic characteristics of women and their husbands, other experiences with violence, husband's behaviours, family support, and context-specific variables such as the sex of their children. Fifteen independent factors remained strongly associated with IPV. Significant risk was associated with husbands' behaviour that supports male power (extra-marital relationships; fighting with other men) and alcohol use. Violence experienced in childhood increased the likelihood of women experiencing and of men perpetrating IPV. Notable was further the association with women's higher financial contribution to the household and lack of association with not having sons. The findings support theories describing how underlying gender and power imbalance are fundamental causes of IPV and indicate the need for context-specific interventions.

This study explored the relationship between intimate partner violence (IPV) and family planning among adolescent girls and young women in formal unions in the Philippines. Analyzing a sample (n =1,566) from the 2013 Philippines Demographic and Health Survey, logistic regression models were separately run for current contraception use and unmet need for family planning on recent physical violence (yes/no), recent sexual violence (yes/no), and recent emotional (yes/no). Findings revealed that the odds of using contraception were significantly higher among girls and young women who reported recent physical IPV (OR=1.84; 95% CI=1.13, 2.99; p<0.05) and sexual IPV (OR=2.18; 95% CI=1.17, 4.06; p<0.05). No significant relationship between recent emotional IPV and contraception use was found. Having an unmet need for family planning showed no significant relationship to IPV. The study adds to a growing body of literature revealing a positive association between IPV and contraception use. Findings hold implications for the provision of family planning services for adolescents and young women in response to the recent passage of landmark legislation pertaining to reproductive health in the Philippines, the Responsible Parenthood and Reproductive Health Act.

Children exposed to intimate partner violence (IPV) are at increased risk for developing traumatic stress symptoms and posttraumatic stress disorder (PTSD). Unfortunately, children who witness IPV are often exposed to additional traumatic events. Previous research has indicated that approximately one third of children experience 2 or more direct victimizations each year, and that exposure to one type of victimization places children at risk for exposure to additional types of victimization. Yet little is known about the impact of these additional traumas on children's functioning. For a sample of 120 preschool children (age 4-6 years) exposed to IPV in the past 2 years, 38% were exposed to additional traumatic events, including sexual assaults by family members, physical assaults, serious accidents, and/or life-threatening illnesses. Those exposed to both IPV and additional traumatic events had higher rates of PTSD diagnoses, traumatic stress symptoms (d = 0.96), and internalizing (d = 0.86) and externalizing behavior (d = 0.47) problems, than those exposed to IPV alone. We also compared DSM-IV diagnostic criteria to proposed criteria for evaluating traumatic stress in preschool-aged children. Results revealed the importance of conducting a complete assessment of traumatic events prior to treating children exposed to IPV.

2012-01-01

This study investigated intimate partner violence in interracial and monoracial relationships. Using a nationally representative sample, regression analyses indicated that interracial couples demonstrated a higher level of mutual IPV than monoracial white couples but a level similar to monoracial black couples. There were significant gender differences in IPV, with women reporting lower levels of victimization than men. Regarding relationship status, cohabiting couples demonstrated the highest levels of IPV and dating couples reported the lowest levels. Regarding interactions among couple racial composition, relationship status, and respondents’ gender, an interaction between racial composition and relationship status was found. Implications for practitioners and directions for future research are discussed. PMID:23554541

Reducing violence against women is a global public health priority, particularly in low-income and conflict-affected societies. However, more needs to be known about the causes of intimate partner violence (IPV) in these settings, including the stress of bride price obligations. The representative study of women attending ante-natal clinics in Dili, Timor-Leste was conducted between June, 2013 and September, 2014 with 1672 pregnant women, a response rate of 96%. We applied contextually developed measures for the stress of bride price and poverty, and the World Health Organisation measure for intimate partner violence. Compared to those with no problems with bride price, women with moderate or serious problems with that custom reported higher rates of IPV (18.0% vs. 43.6%). Adjusting for socio-demographic factors, multivariate analysis revealed that ongoing poverty (OR = 1.75, 95% CI: 1.20-2.56) was significantly associated with IPV. Importantly, the strongest association with IPV was problems with bride price (OR = 2.73, 95% CI: 1.86-4.01). This is the first large consecutively sampled study to demonstrate a strong association between the stressors of bride price and poverty with IPV. Notably, bride price stress had the strongest association with IPV. Revealing this hitherto unrecognized factor of bride price stress may prove pivotal in guiding policy and interventions aimed at reducing IPV, and thereby improve the health and psychosocial status of women in low income and conflict-affected settings.

Phase II and III clinical studies were conducted to evaluate immunogenicity and safety of a novel DTaP-IPV vaccine consisting of Sabin inactivated poliovirus vaccine (sIPV) and diphtheria-tetanus-acellular pertussis vaccine (DTaP). A Phase II study was conducted in 104 healthy infants using Formulation H of the DTaP-sIPV vaccine containing high-dose sIPV (3, 100, and 100 D-antigen units for types 1, 2, and 3, respectively), and Formulations M and L, containing half and one-fourth of the sIPV in Formulation H, respectively. Each formulation was administered 3 times for primary immunization and once for booster immunization. A Phase III study was conducted in 342 healthy infants who received either Formulation M + oral polio vaccine (OPV) placebo or DTaP + OPV. The OPV or OPV placebo was orally administered twice between primary and booster immunizations. Formulation M was selected as the optimum dose. In the Phase III study, the seropositive rate was 100% for all Sabin strains after primary immunization, and the neutralizing antibody titer after booster immunization was higher than in the control group (DTaP + OPV). All adverse reactions were clinically acceptable. DTaP-sIPV was shown to be a safe and immunogenic vaccine.

This study investigates the influence of neighbourhood socioeconomic conditions on women's likelihood of experiencing intimate partner violence (IPV) in Sao Paulo, Brazil. Data from 940 women who were interviewed as part of the WHO multi-country study on women's health and domestic violence against women, and census data for Sao Paulo City, were analyzed using multilevel regression techniques. A neighbourhood socioeconomic-level scale was created, and proxies for the socioeconomic positions of the couple were included. Other individual level variables included factors related to partner's behaviour and women's experiences and attitudes. Women's risk of IPV did not vary across neighbourhoods in Sao Paulo nor was it influenced by her individual socioeconomic characteristics. However, women in the middle range of the socioeconomic scale were significantly more likely to report having experienced violence by a partner. Partner behaviours such as excessive alcohol use, controlling behaviour and multiple sexual partnerships were important predictors of IPV. A women's likelihood of IPV also increased if either her mother had experienced IPV or if she used alcohol excessively. These findings suggest that although the characteristics of people living in deprived neighbourhoods may influence the probability that a woman will experience IPV, higher-order contextual dynamics do not seem to affect this risk. While poverty reduction will improve the lives of individuals in many ways, strategies to reduce IPV should prioritize shifting norms that reinforce certain negative male behaviours.

Gómez, Anu Manchikanti; Speizer, Ilene S

Gender-based violence is an important risk factor for adverse reproductive health (RH). Community-level violence may inhibit young women's ability to engage in safer sexual behaviors due to a lack of control over sexual encounters. Few studies examine violence as a contextual risk factor. Using nationally representative data from five African countries, the association between community-level physical or sexual intimate partner violence (IPV) and the circumstances of first sex (premarital or marital) among young women (ages 20-29) was examined. In Mali, and Kenya bivariate analyses showed that young women who had premarital first sex were from communities where a significantly higher percentage of women reported IPV experience compared to young women who had marital first sex. Multivariate analyses confirmed the findings for these two countries; young women from communities with higher IPV were significantly more likely to have had premarital first sex compared to first sex in union. In Liberia, community-level IPV was associated with a lower risk of premarital sex as compared to first sex in union at a marginal significance level. There was no significant relationship between community-level IPV and the circumstances of first sex in the Democratic Republic of Congo or Zimbabwe. These findings indicate that context matters for RH. Individualized efforts to improve RH may be limited in their effectiveness if they do not acknowledge the context of young women's lives. Programs should target prevention of violence to improve RH outcomes of youth.

Is There a Cumulative Association Between Adverse Childhood Experiences and Intimate Partner Violence in Emerging Adulthood?

2017-12-01

Adverse childhood experiences (ACEs) have been shown to cumulatively predict a range of poor physical and mental health outcomes across adulthood. The cumulative effect of ACEs on intimate partner violence (IPV) in emerging adulthood has not been previously explored. The current study examined the individual and cumulative associations between nine ACEs (emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, witnessing domestic violence, living with a mentally ill, substance abusing, or incarcerated household member) and IPV in a diverse sample of college students ( N = 284; M age = 20.05 years old [ SD = 2.5], 32% male, 37% Caucasian, 30% Asian, 33% other, and 27% Hispanic) from an urban, public college in the Northeast of the United States. Participants reported ACEs (measured by the Adverse Childhood Experiences Survey) and IPV perpetration and victimization (measured with the Revised Conflict Tactics Scale-2) of physical and psychological aggression in an online study that took place from 2015 to 2016. Bivariate and multivariate associations between ACEs, cumulative ACEs (assessed by the sum of adverse experiences), and IPV outcomes were assessed, while controlling for demographics and socioeconomic status. No cumulative associations were observed between ACEs and any of the IPV subscales in multivariate regressions, while witnessing domestic violence was significantly associated with perpetration and victimization of physical aggression and injury, and household member incarceration and physical abuse were associated with physical aggression perpetration. Adverse childhood events do not seem to associate cumulatively with IPV in emerging adulthood and the contributions of individual childhood experiences appear to be more relevant for IPV outcomes. Clinical and research implications are discussed.

Examining the offender-victim overlap among police officers: the role of social learning and job-related stress.

This study uses data from the Police Stress and Domestic Violence in Police Families in Baltimore, Maryland 1997-1999 to examine the offender-victim overlap among police officers in the context of intimate partner violence (IPV). Specifically, the study examines the role of parental violence, child maltreatment, and job-related stress on perpetrating violence and victimization. Results from two logistic regression models indicate that one element of job-related stress (negative emotions) was positive and significant in predicting IPV perpetration, whereas parental violence, child maltreatment, and negative emotions were found to be positive and significant in predicting victimization. The study's limitations and future research are discussed.

The effects of different types of intimate partner violence (IPV) on mental health are understudied. The aim of this study was to analyse the association between women's mental health and physical, psychological and sexual IPV. We invited subjects of a population-based survey conducted in 2015 in Rasht, Iran, on IPV against women to complete the General Health Questionnaire (GHQ-28). The present research study is a secondary study based on these data and archival data from the 2015 study. For analysis, multivariate analysis of covariance was used. Additionally, predictors of IPV were evaluated using linear regression. A total of 2091 married women were surveyed. The participants were divided into abused women (n = 512, 24.5%) and non-abused women (n = 1579, 75.5%). The pattern of IPV among our patients showed more instances of psychological aggression than physical assault, sexual coercion or injury. Our results show that the non-psychotic psychiatric disorders of the victims were significantly impaired in all aspects, including somatic symptoms, anxiety/insomnia, social dysfunction, and depression. Except social dysfunction, the psychological and sexual abuse were significant predictors of other aspects of mental health. Our findings suggest that risk of IPV is high in this population. They also indicate that various forms of abuse are different from each other in terms of predicting a victim's mental health. Different strategies may be required to reduce and prevent this violence. Additional research is needed to confirm and expand upon our findings.

Background Physicians are generally poorly trained to recognize, treat or refer adolescents at risk for intimate partner violence (IPV). Participation in community programs may improve medical students’ knowledge, skills, and attitudes about IPV prevention. Objective To determine whether the experience of serving as educators in a community-based adolescent IPV prevention program improves medical students’ knowledge, skills, and attitudes toward victims of IPV, beyond that of didactic training. Participants One hundred and seventeen students attending 4 medical schools. Design Students were randomly assigned to didactic training in adolescent IPV prevention with or without participation as educators in a community-based adolescent IPV prevention program. Students assigned to didactic training alone served as community educators after the study was completed. Measurement Knowledge, self-assessment of skills and attitudes about intimate partner violence and future plans to pursue outreach work. Results The baseline mean knowledge score of 10.25 improved to 21.64 after didactic training (p ≤ .001). Medical students in the “didactic plus outreach” group demonstrated higher levels of confidence in their ability to address issues of intimate partner violence, (mean = 41.91) than did students in the “didactic only” group (mean = 38.94) after controlling for initial levels of confidence (p ≤ .002). Conclusions Experience as educators in a community-based program to prevent adolescent IPV improved medical students’ confidence and attitudes in recognizing and taking action in situations of adolescent IPV, whereas participation in didactic training alone significantly improved students’ knowledge.

Intimate partner violence (IPV) is reported by one in five women globally, but the prevalence is much higher in East Africa. Though some formal and informal resources do exist for women experiencing IPV, data suggest that disclosure, help seeking, and subsequent utilization of these resources are often hindered by socio-cultural, economic, and institutional factors. This paper explores actions taken by victims, available support services, and barriers to utilization of available IPV resources by pregnant women in rural Nyanza, Kenya. Qualitative data were collected through 9 focus group discussions and 20 in-depth interviews with pregnant women, partners or male relatives of pregnant women, and service providers. Data were managed in NVivo 8 using a descriptive analytical approach that harnessed thematic content coding and in-depth grounded analysis. We found that while formal resources for IPV were scarce, women utilized many informal resources (family, pastors, local leaders) as well as the health facility. In rare occasions, women escalated their response to formal services (police, judiciary). The community was sometimes responsive to women experiencing IPV, but often viewed it as a “normal” part of local culture. Further barriers to women accessing services included logistical challenges and providers who were under-trained or uncommitted to responding to IPV appropriately. Moreover, the very sanctions meant to address violence (such as fines or jail) were often inhibiting for women who depended on their partners for financial resources. The results suggest that future IPV interventions should address community views around IPV and build upon locally available resources – including the health clinic - to address violence among women of child-bearing age.

A substantial body of literature has documented the negative effects of intimate partner violence (IPV) on a wide range of children's developmental outcomes. However, whether a child's exposure to IPV leads to increased adjustment difficulties is likely to depend on a variety of factors, including the caregiver's mental health and the developmental time period when IPV exposure occurs. The present study seeks to improve our understanding of the long-term effects of IPV exposure and maternal depression on the development of children's overt aggressive behavior. Longitudinal analyses (i.e., latent growth curve modeling) examining three time points (toddler: age 2-3 years, preschool/kindergarten: age 4-5 years, and elementary school: age 6-8 years) were conducted using 1,399 at-risk children drawn from the National Survey of Child and Adolescent Well-Being (NSCAW-I). IPV exposure during age 2-3 years was significantly related to concurrent aggressive behavior and aggressive behavior during age 4-5 years. At all three time points, IPV was significantly associated with maternal depression, which in turn, was significantly related to higher levels of aggressive behavior. There was also a significant indirect lagged effect of IPV exposure at age 2-3 years through maternal depression on aggressive behavior at age 4-5 years. Results indicated that maternal depression was a strong predictor of increased reports of overt aggressive behavior, suggesting that interventions to buffer the effects of IPV exposure should focus on relieving maternal depression and fostering productive social behavior in children.

Risk for unmet need for contraception is associated with men's perpetration of intimate partner violence (IPV) against women and may be influenced by violence perpetrated by other family members (family violence, FV). Women who married as minors may be most vulnerable to the potential compounding effect of IPV and FV on unmet need. Using nationally representative data from the 2012 Jordan Population and Family Health Survey we examined unmet need by exposure to IPV and FV by women's age at marriage (<18, 18+ years). Logistic regression was used to test whether IPV and FV were independently associated with unmet need, by age at marriage. Interaction terms (IPV×FV) were tested in both models. Stratification by FV was employed to clarify the interpretation of significant interactions. IPV increased the odds of unmet need by 87% [adjusted odds ratio (AOR) 1.87; 95% confidence interval (95% CI) 1.13-3.10] and 76% (AOR 1.76; 95% CI 1.30-2.38) among women who married prior to and after the age of 18 years, respectively. Women married as minors who experienced IPV and FV had a four-fold higher likelihood of having an unmet need (AOR 6.75; 95% CI 1.95-23.29) compared to those experiencing only IPV (AOR 1.49; 95% CI 0.84-2.38). No interaction between IPV and FV was detected for women married at or above majority. Laws that prohibit child marriage should be strengthened and health sector screening for violence experience could help identify women at risk of unmet need and improve women's reproductive agency.

This study assesses whether IPV is associated with poor reproductive and maternal health outcomes, as well as whether poverty exacerbates any observed associations, among women who gave birth in the preceding 23 months in Bihar, India. A cross-sectional analysis of data from a representative household sample of mothers of children 0-23 months old in Bihar, India (N = 13,803) was conducted. Associations between lifetime IPV (physical and/or sexual violence) and poor reproductive health outcomes ever (miscarriage, stillbirth, and abortion) as well as maternal complications for the index pregnancy (early and/or prolonged labor complications, other complications during pregnancy or delivery) were assessed using multivariable logistic regression, adjusting for demographics and fertility history of the mother. Models were then stratified by wealth index to determine whether observed associations were stronger for poorer versus wealthier women. IPV was reported by 45% of women in the sample. A history of miscarriage, stillbirth, and abortion was reported by 8.7, 4.6, and 1.3% of the sample, respectively. More than one in 10 women (10.7%) reported labor complications during the last pregnancy, and 16.3% reported other complications during pregnancy or delivery. Adjusted regressions revealed significant associations between IPV and miscarriage (AOR = 1.35, 95% CI = 1.11-1.65) and stillbirth (AOR = 1.36, 95% CI = 1.02-1.82) ever, as well as with labor complications (AOR = 1.27, 95% CI = 1.04-1.54) and other pregnancy/delivery complications (AOR = 1.68, 95% CI = 1.42-1.99). Women in the poorest quartile (Quartile 1) saw no associations between IPV and miscarriage (Quartile 1 AOR = 0.98, 95% CI = 0.67-1.45) or stillbirth (Quartile 1 AOR = 1.17, 95% CI = 0.69-1.98), whereas women in the higher wealth quartile (Quartile 3) did see associations between IPV and miscarriage (Quartile 3 AOR = 1.55, 95% CI = 1.07, 2.25) and stillbirth (Quartile 3 AOR = 1.79, 95% CI = 1.04, 3.08). IPV is highly prevalent in Bihar and is associated with increased risk for miscarriage, stillbirth, and maternal health complications. Associations between IPV and miscarriage and stillbirth do not hold true for the poorest women, possibly because other risks attached to poverty and deprivation may be greater contributors.

The purpose of the current study is to explore the revictimization process between child abuse and neglect (CAN), and intimate partner violence (IPV) based on the schema theory perspective. For this aim, 222 married women recruited in four central cities of Turkey participated in the study. Results indicated that early negative CAN experiences increased the risk of being exposed to later IPV. Specifically, emotional abuse and sexual abuse in the childhood predicted the four subtypes of IPV, which are physical, psychological, and sexual violence, and injury, while physical abuse only associated with physical violence. To explore the mediational role of early maladaptive schemas (EMSs) on this association, first, five schema domains were tested via Parallel Multiple Mediation Model. Results indicated that only Disconnection/Rejection (D/R) schema domains mediated the association between CAN and IPV. Second, to determine the particular mediational roles of each schema, eighteen EMS were tested as mediators, and results showed that Emotional Deprivation Schema and Vulnerability to Harm or Illness Schema mediated the association between CAN and IPV. These findings provided an empirical support for the crucial roles of EMSs on the effect of revictimization process. Clinical implications were discussed. Copyright © 2016 Elsevier Ltd.

Polio is on the brink of eradication. Improved inactivated polio vaccines (IPV) are needed towards complete eradication and for the use in the period thereafter. Vaccination via mucosal surfaces has important potential advantages over intramuscular injection using conventional needle and syringe, the currently used delivery method for IPV. One of them is the ability to induce both serum and mucosal immune responses: the latter may provide protection at the port of virus entry. The current study evaluated the possibilities of polio vaccination via mucosal surfaces using IPV based on attenuated Sabin strains. Mice received three immunizations with trivalent sIPV via intramuscular injection, or via the intranasal or sublingual route. The need of an adjuvant for the mucosal routes was investigated as well, by testing sIPV in combination with the mucosal adjuvant cholera toxin. Both intranasal and sublingual sIPV immunization induced systemic polio-specific serum IgG in mice that were functional as measured by poliovirus neutralization. Intranasal administration of sIPV plus adjuvant induced significant higher systemic poliovirus type 3 neutralizing antibody titers than sIPV delivered via the intramuscular route. Moreover, mucosal sIPV delivery elicited polio-specific IgA titers at different mucosal sites (IgA in saliva, fecal extracts and intestinal tissue) and IgA-producing B-cells in the spleen, where conventional intramuscular vaccination was unable to do so. However, it is likely that a mucosal adjuvant is required for sublingual vaccination. Further research on polio vaccination via sublingual mucosal route should include the search for safe and effective adjuvants, and the development of novel oral dosage forms that improve antigen uptake by oral mucosa, thereby increasing vaccine immunogenicity. This study indicates that both the intranasal and sublingual routes might be valuable approaches for use in routine vaccination or outbreak control in the period after complete OPV cessation and post-polio eradication.

Intimate partner violence (IPV) is a growing public health problem, and gaps exist in knowledge with respect to appropriate prevention and treatment strategies. A growing body of research evidence suggests that beyond individual factors (e.g., socio-economic status, psychological processes, substance abuse problems), neighborhood characteristics, such as neighborhood economic disadvantage, high crime rates, high unemployment and social disorder, are associated with increased risk for IPV. However, existing research in this area has focused primarily on risk factors inherent in neighborhoods, and has failed to adequately examine resources within social networks and neighborhoods that may buffer or prevent the occurrence of IPV. This study examines the effects of neighborhood characteristics, such as economic disadvantage and disorder, and individual and neighborhood resources, such as social capital, on IPV among a representative sample of 2412 residents of Toronto, Ontario, Canada. Using a population based sample of 2412 randomly selected Toronto adults with comprehensive neighborhood level data on a broad set of characteristics, we conducted multi-level modeling to examine the effects of individual- and neighborhood-level effects on IPV outcomes. We also examined protective factors through a comprehensive operationalization of the concept of social capital, involving neighborhood collective efficacy, community group participation, social network structure and social support. Findings show that residents who were involved in one or more community groups in the last 12 months and had high perceived neighborhood problems were more likely to have experienced physical IPV. Residents who had high perceived social support and low perceived neighborhood problems were less likely to experience non-physical IPV. These relationships did not differ by neighborhood income or gender. Findings suggest interesting contextual effects of social capital on IPV. Consistent with previous research, higher levels of perceived neighborhood problems can reflect disadvantaged environments that are more challenged in promoting health and regulating disorder, and can create stressors in which IPV is more likely to occur. Such analyses will be helpful to further understanding of the complex, multi-level pathways related to IPV and to inform the development of effective programs and policies with which to address and prevent this serious public health issue.

Pulmonary infections can be life threatening for children with neuromuscular diseases who have impaired ability to clear secretions. Intrapulmonary percussive ventilation (IPV) is a pneumatic device that delivers air and aerosol to the lungs at frequencies of 200 to 300 cycles per minute at peak pressures from 20 to 40 cm H(2)O. Anecdotal reports and pilot studies show its safety and effectiveness in mobilizing secretions in patients with cystic fibrosis. To test the hypothesis that IPV used in a pulmonary program for adolescents with neuromuscular disease would reduce the number of days of antibiotic use for pulmonary infection. A randomized, controlled study was conducted to compare efficacy of IPV with incentive spirometry (IS) in reducing number of days of antibiotic use in adolescents with neuromuscular disease. The secondary endpoints were the number of respiratory infections, hospitalizations, and school days missed. A total of 18 patients were enrolled (9 IPV, 9 IS). Antibiotic use was significantly higher with IS (24/1000 patient-days) compared with IPV (0/1000 patient-days), (incidence rate ratio, 43; 95% confidence interval, 6-333). The IS group spent more days hospitalized (4.4/1000 patient-days vs 0/1000 patient-days) than the IPV group (incidence rate ratio, 8.5; 95% confidence interval, 1.1-67). The IPV group had 0 episodes of pneumonia or bacterial bronchitis compared with 3 events in the IS group, although this did not meet statistical significance. Intrapulmonary percussive ventilation as part of a preventive pulmonary regimen reduced days of antibiotic use and hospitalization for respiratory illness in adolescents with neuromuscular disease.

Police violence has been identified as a public health concern in the U.S., yet few studies have assessed the prevalence and nature of police violence among women. Furthermore, increasing evidence suggests that women reporting intimate partner violence (IPV) and sexual violence (SV) to police are often met with harmful or neglectful police responses and thus, women's exposures to police violence may be associated with experiences of IPV and SV; however, this has not yet been empirically tested. This study assesses lifetime prevalence and sociodemographic correlates of police violence among women and investigates potential associations between IPV, SV, and police violence. A cross-sectional survey was administered in four Eastern U.S. cities in March and April 2016 (N=932). Physical, sexual, and psychological police victimization and neglect by police were assessed. Logistic regression was used to examine the relationship between IPV, SV, and police violence, adjusting for sociodemographics. Lifetime prevalence of physical (4%), sexual (3.3%), and psychological (14.4%) police violence and neglect (17.2%), show that a notable proportion of women experience police victimization, with significantly higher rates among racial and ethnic minority women. Women with IPV and SV histories had increased odds of experiencing most forms of police violence compared to women without IPV and SV histories. Findings suggest the need for gender-inclusive community-centered policing initiatives and other preventive efforts aimed at eliminating police violence. Police violence and victimization among women should also be considered in IPV and SV intervention and treatment responses. Copyright © 2017 Elsevier Inc. All rights reserved.

Child marriage (before age 18) is a risk factor for intimate partner violence (IPV) against women. Worldwide, Bangladesh has the highest prevalence of IPV and very early child marriage (before age 15). How the community prevalence of very early child marriage influences a woman's risk of IPV is unknown. Using panel data (2013-2014) from 3,355 women first married 4-12 years prior in 77 Bangladeshi villages, we tested the protective effect of a woman's later first marriage (at age 18 or older), the adverse effect of a higher village prevalence of very early child marriage, and whether any protective effect of a woman's later first marriage was diminished or reversed in villages where very early child marriage was more prevalent. Almost one-half (44.5 %) of women reported incident physical IPV, and 78.9 % had married before age 18. The village-level incidence of physical IPV ranged from 11.4 % to 75.0 %; the mean age at first marriage ranged from 14.8 to 18.0 years. The mean village-level prevalence of very early child marriage ranged from 3.9 % to 51.9 %. In main-effects models, marrying at 18 or later protected against physical IPV, and more prevalent very early child marriage before age 15 was a risk factor. The interaction of individual later marriage and the village prevalence of very early child marriage was positive; thus, the likely protective effect of marrying later was negated in villages where very early child marriage was prevalent. Collectively reducing very early child marriage may be needed to protect women from IPV.

Introduction High intrapatient variability (IPV) in tacrolimus trough levels has been shown to be associated with higher rates of renal transplant failure. There is no consensus on what level of IPV constitutes a risk of graft loss. The establishment of such a threshold could help to guide clinicians in identifying at-risk patients to receive targeted interventions to improve IPV and thus outcomes. Methods and analysis A multicentre Transplant Audit Collaborative has been established to conduct a retrospective study examining tacrolimus IPV and renal transplant outcomes. Patients in receipt of a renal transplant at participating centres between 2009 and 2014 and fulfilling the inclusion criteria will be included in the study. The aim is to recruit a minimum of 1600 patients with follow-up spanning at least 2 years in order to determine a threshold IPV above which a renal transplant recipient would be considered at increased risk of graft loss. The study also aims to determine any national or regional trends in IPV and any demographic associations. Ethics and dissemination Consent will not be sought from patients whose data are used in this study as no additional procedures or information will be required from participants beyond that which would normally take place as part of clinical care. The study will be registered locally in each participating centre in line with local research and development protocols. It is anticipated that the results of this audit will be disseminated locally, in participating NHS Trusts, through national and international meetings and publications in peer-reviewed journals.

Smoking prevalence among women who experience intimate partner violence (IPV) is two to three times higher than the prevalence among women nationally. Yet, research on cigarette smoking among this population of women is scarce. This study examined differences between daily smokers and non-smokers among a sample of 186 IPV-victimized women. Comparing these groups may identify key factors that could inform future research, and ultimately, smoking cessation interventions to improve women's health. Results showed that smokers and non-smokers differed in terms of alcohol and drug use problem severity, posttraumatic stress symptom severity, psychological and physical IPV victimization severity, and severity of use of psychological and physical IPV. Smokers fared worse on all domains where differences emerged. Findings of a logistic regression demonstrated that alcohol problem severity was related to daily smoking status; post hoc analysis revealed that the effect of alcohol problem severity was moderated by the level of Posttraumatic stress disorder (PTSD) avoidance symptom severity. Findings suggest a sub-population of women experiencing IPV who smoke and incur additional risk for psychiatric symptom severity and maladaptive behaviors. This study suggests the need to examine factors such as IPV and its negative sequelae to inform smoking cessation research for women. This study contributes to the scarce literature examining the intersections of PTSD, alcohol and drug use, and smoking. Examining these factors in the context of IPV, which is a highly prevalent problem, is critical to informing future treatment development investigations. © American Academy of Addiction Psychiatry.

Intimate partner violence (IPV) perpetrators have been categorized into two groups based on their heart rate (HR) reactivity to stress following Gottman's studies. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II or reactive perpetrators present a hyper-reactivity in anticipation of stress. In this study, changes in HR, pre-ejection period (PEP), vagal ratio as well as psychological state variables (anxiety and anger) in response to stress were assessed, comparing a group of type II IPV perpetrators (based on violence reports and psychological assessment; n = 17; mean age = 37) with non-violent controls (n = 17; mean age = 35) using modified version of the Trier Social Stress Test. IPV perpetrators had higher HRs and lower vagal ratios than controls, particularly during the recovery period. Moreover, the former presented shorter PEPs than controls. There were no differences between groups in the magnitude of response of the HR, PEP or vagal ratio. High baseline anxiety and anger were associated with an HR increase during the preparation time in IPV perpetrators but not in controls. These findings indicate a different cardiovascular pattern of response to psychosocial stress in IPV perpetrators, especially during recovery. Thus, they contribute to understanding the biological functioning of violence sub-types, supporting the validity of cardiovascular measures as diagnostic indicators for IPV classification.

Men with antisocial personality disorder (ASPD) traits are at an increased risk for consuming alcohol and perpetrating intimate partner violence (IPV). However, previous research has neglected malleable mechanisms potentially responsible for the link between ASPD traits, alcohol problems, and IPV perpetration. Efforts to improve the efficacy of batterer intervention programs (BIPs) would benefit from exploration of such malleable mechanisms. The present study is the first to examine distress tolerance as one such mechanism linking men's ASPD traits to their alcohol problems and IPV perpetration. Using a cross-sectional sample of 331 men arrested for domestic violence and court-referred to BIPs, the present study used structural equation modeling to examine pathways from men's ASPD traits to IPV perpetration directly and indirectly through distress tolerance and alcohol problems. Results supported a two-chain partial mediational model. ASPD traits were related to psychological aggression perpetration directly and indirectly via distress tolerance and alcohol problems. A second pathway emerged by which ASPD traits related to higher levels of alcohol problems, which related to psychological aggression perpetration. Controlling for psychological aggression perpetration, neither distress tolerance nor alcohol problems explained the relation between ASPD traits and physical assault perpetration. These results support and extend existing conceptual models of IPV perpetration. Findings suggest intervention efforts for IPV should target both distress tolerance and alcohol problems.

Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruption. Mobile IPv6 was proposed to provide mobility support to IPv6-based mobile nodes for continuous communication when they roam across different networks. However, the Route Optimization procedure in Mobile IPv6 involves the verification of mobile node's reachability at the home address and at the care-of address (home test and care-of test) that results in higher handover delays and signalling overhead. This paper presents an enhanced procedure, time-based one-time password Route Optimization (TOTP-RO), for Mobile IPv6 Route Optimization that uses the concepts of shared secret Token, time based one-time password (TOTP) along with verification of the mobile node via direct communication and maintaining the status of correspondent node's compatibility. The TOTP-RO was implemented in network simulator (NS-2) and an analytical analysis was also made. Analysis showed that TOTP-RO has lower handover delays, packet loss, and signalling overhead with an increased level of security as compared to the standard Mobile IPv6's Return-Routability-based Route Optimization (RR-RO).

Intimate partner violence (IPV) against women, particularly those living in poverty who have multiple marginalized identities, is a significant public health issue. IPV is associated with numerous mental health concerns including depression, hopelessness, and suicidal behavior. The present study examined the ecological determinants of these mental health outcomes in a high-risk sample of 67 low-income, African American women survivors of IPV. Based on an ecological framework that conceptualizes individuals as nested in multiple, interactive systems, we examined, longitudinally, the main and interactive effects of self-reported neighborhood disorder and social support from family members and friends on participants' mental health (i.e., self-reported depressive symptoms, hopelessness, and suicide intent). In multiple regression analyses, neighborhood disorder interacted with social support from family members to predict depressive symptoms and hopelessness over time. Neighborhood disorder also interacted with social support from friends to predict hopelessness and suicide intent over time. High levels of social support buffered against the dangerous effects of neighborhood disorder on depressive symptoms, hopelessness, and suicide intent; at low levels of social support, there was no significant association between neighborhood disorder and those mental health outcomes. Neighborhood disorder and social support did not yield significant main effects. These findings underscore the importance of interventions that target individuals, families, and communities (e.g., community empowerment programs). Group interventions may also be important for low-income, African American women survivors of IPV, as they can help survivors establish and strengthen relationships and social support.

Little is known about the extent to which parental conflict and violence differentially impact on offspring mental health and substance use. Using data from a longitudinal birth cohort study this paper examines: whether offspring exposure to parental intimate partner violence (involving physical violence which may include conflicts and/or disagreements) or parental intimate partner conflict (conflicting interactions and disagreements only) are associated with offspring depression, anxiety and substance use in early adulthood (at age 21); and whether these associations are independent of maternal background, depression and anxiety and substance use. Data (n=2,126 women and children) were taken from a large-scale Australian birth-cohort study, the Mater University of Queensland Study of Pregnancy (MUSP). IPC and IPV were measured at the 14-year follow-up. Offspring mental health outcomes--depression, anxiety and substance use--were assessed at the 21-year follow-up using the Composite International Diagnostic Interview (CIDI). Offspring of women experiencing IPV at the 14-year follow-up were more likely to manifest anxiety, nicotine, alcohol and cannabis disorders by the 21-year follow-up. These associations remained after adjustment for maternal anxiety, depression, and other potential confounders. Unlike males who experience anxiety disorders after exposure to IPV, females experience depressive and alcohol use disorders. IPV predicts offspring increased levels of substance abuse and dependence in young adulthood. Gender differences suggest differential impact. Copyright © 2014 Elsevier Ltd. All rights reserved.

Combination vaccines simplify vaccination visits and improve coverage and timeliness. DTaP5-HB-IPV-Hib is a new investigational, fully-liquid, combination vaccine designed to protect against 6 infectious diseases, including 5 pertussis antigens and OMPC instead of PT as conjugated protein for Hib component. In this multicenter, double-blind, comparator-controlled, Phase III study (NCT01480258) conducted in Sweden, Italy, and Finland, healthy infants were randomized 1:1 to receive one two immunization regimens. The DTaP5-HB-IPV-Hib Group received the investigational hexavalent vaccine (DTaP5-HB-IPV-Hib) and the Control Group received Infanrix-hexa (DTPa3-HBV-IPV/Hib) at 2, 4 and 11-12months of age. Both groups received concomitantly Prevnar 13 (PCV13) and Rotateq (RV5) or Rotarix (RV1) at 2, 4months of age and PCV13 at 11-12months. Subjects administered RV5 received a 3rd dose at 5months of age. A total of 656 subjects were randomized to the DTaP5-HB-IPV-Hib Group and 659 subjects to Control Group. Immune responses to all vaccine antigens post-toddler dose were non-inferior in the DTaP5-HB-IPV-Hib Group as compared to the Control Group. Additionally, the post-dose 2 and pre-toddler DTaP5-HB-IPV-Hib anti-PRP responses were superior. The DTaP5-HB-IPV-Hib Group responses to concomitant RV1 were non-inferior compared to the Control Group. Solicited adverse event rates after any dose were similar in both groups, except for higher rates of pyrexia (6.4% difference; 95% CI: 1.5,11.3) and somnolence (5.8% difference; 95% CI: 1.7,9.8) in the DTaP5-HB-IPV-Hib Group. Vaccine-related serious adverse events occurred infrequently in the DTaP5-HB-IPV-Hib Group (0.3%) and the Control Group (0.5%). The safety and immunogenicity of DTaP5-HB-IPV-Hib is generally comparable to Control when administered in the 2, 4, 11-12month schedule. Early Hib responses were superior versus Control. DTaP5-HB-IPV-Hib could provide a new hexavalent option for pediatric combination vaccines, aligned with recommended immunizations in Europe. V419-008 CLINICALTRIALS.GOV identifier: NCT01480258.

One-third of the women worldwide experience intimate partner violence (IPV) that increases their vulnerability to both short- and long-term physical, sexual, reproductive, and mental health problems. Surprisingly, IPV is justified by many women globally. Although the IPV literature to date is mostly focused on risk factors associated with actual occurrences, little is known on attitudinal acceptance of such violence. Also, despite the growing scholarship of community influence and health link, IPV research has relatively overlooked the effects of norms at the community level. Using a representative national sample of 13,611 married women in Bangladesh, this study examined the association of community attitudes and women's individual attitudes toward wife beating. The results revealed that women living in communities with permissive attitudes toward wife beating were more likely to justify husbands' beating (OR=4.5). Women married at a younger age, who had less than primary-level education, lived in households categorized as poor or middle class, and did not consume media appeared to be at higher risk for justifying wife beating. This research adds to a growing research body on community influences on health by examining IPV attitudes and community norms link.

Associations between marital intimate partner violence (IPV) and postseparation coparenting relationship trajectories were examined among 135 mothers who participated in 5 interviews at 3-month intervals in the year following their divorce filing. Growth curve analysis was conducted to assess change and variability in coparenting dimensions (i.e., conflict, support, communication about child rearing, and harassment) in the overall sample and by type of IPV. In the overall sample, coparenting conflict, communication about child rearing, and harassment decreased across the year following separation. However, coparenting relationships differed considerably based on marital IPV experiences. At Time 1, mothers in relationships with coercive controlling violence (CCV) reported higher levels of harassment and conflict, and lower levels of support and communication about coparenting, than mothers with situational couple violence (SCV) or no violence (NV). Furthermore, coparenting relationship trajectories differed significantly by IPV group, with mothers who experienced CCV showing more variability in conflict and harassment, and more marked changes in conflict, support, and harassment. Despite many similarities, mothers with SCV showed higher initial levels of harassment compared to mothers with NV. Findings can support family court and social service professionals' efforts to individualize interventions with divorcing parents based on IPV experiences. In cases of CCV, for example, attention to heightened control dynamics in the immediate separation period remain critical but the persistent volatility across the first year suggests the potential for chronic stress. With SCV, practitioners may be able to capitalize on parents' reasonable levels of communication and steady coparenting support. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This study examined the associations among posttraumatic stress disorder (PTSD) symptom severity, antisocial personality disorder (ASPD) diagnosis, and intimate partner violence (IPV) in a sample of 145 substance abuse treatment-seeking men and women with positive trauma histories; sex was examined as a moderator. ASPD diagnosis significantly predicted both verbal and physical aggression; sex moderated the association between ASPD diagnosis and physical violence. PTSD symptom severity significantly predicted engaging in verbal, but not physical, aggression. Overall, these results suggest that an ASPD diagnosis may be an important risk factor for engaging in IPV among women seeking treatment for a substance use disorder. © The Author(s) 2015.

There is a demand of affordable IPV in the World. Statens Serum Institut (SSI) has developed three reduced dose IPV formulations adsorbed to aluminium hydroxide; 1/3 IPV-Al, 1/5 IPV-Al and 1/10 IPV-Al SSI, and now report the results of the first investigations in humans. 240 Danish adolescents, aged 10-15years, and childhood vaccinated with IPV were booster vaccinated with 1/3 IPV-Al, 1/5 IPV-Al, 1/10 IPV-Al or IPV Vaccine SSI. The booster effects (GMTRs) of the three IPV-Al SSI were compared to IPV Vaccine SSI, and evaluated for non-inferiority. The pre-vaccination GMTs were similar across the groups; 926 (type 1), 969 (type 2) and 846 (type 3) in the total trial population. The GMTRs by poliovirus type and IPV formulation were: Type 1: 17.0 (1/3 IPV-Al), 13.0 (1/5 IPV-Al), 7.1 (1/10 IPV-Al) and 42.2 (IPV Vaccine SSI). Type 2: 12.5 (1/3 IPV-Al), 13.1 (1/5 IPV-Al), 7.6 (1/10 IPV-Al) and 47.8 (IPV Vaccine SSI). Type 3: 14.5 (1/3 IPV-Al), 16.2 (1/5 IPV-Al), 8.9 (1/10 IPV-Al) and 62.4 (IPV Vaccine SSI) Thus, the three IPV-Al formulations were highly immunogenic, but inferior to IPV Vaccine SSI, in this booster vaccination trial. No SAE and no AE of severe intensity occurred. 59.2% of the subjects reported at least one AE. Injection site pain was the most frequent AE in all groups; from 24.6% to 43.3%. Injection site redness and swelling frequencies were<5% in most and<10% in all groups. The most frequent systemic AEs were fatigue (from 8.2% to 15.0%) and headache (from 15.0% to 28.3%). Most AEs were of mild intensity. In conclusion, the three IPV-Al SSI were safe in adolescents and the booster effects were satisfactory. ClinicalTrials.gov registration number: NCT02280447.

Intimate partner violence (IPV) is exceedingly common in conflict and post-conflict settings. We first seek to describe factors associated with past 12 month IPV amongst currently married women in Afghanistan, focused on the factors typically assumed to drive IPV. Second, to describe whether IPV is independently associated with a range of health outcomes. Cross-sectional analysis of currently married Afghan women, comprising the baseline study of a trial to prevent IPV. We use multinomial regression, reporting adjusted relative-risk ratios to model factors associated with the different forms of IPV, comparing no IPV, emotional IPV only, and physical IPV and emotional IPV. Second we assessed whether experience of emotional IPV, and physical IPV, were independently associated with health outcomes, reporting adjusted ß coefficients and adjusted odds ratios as appropriate. Nine hundred thirty five currently married women were recruited, 11.8% experienced only emotional IPV and 23.1% experienced physical and emotional IPV. Emotional IPV only was associated with attending a women's group, greater food insecurity, her husband having more than one wife, experiencing other forms of family violence, and more inequitable community gender norms. Experiencing both physical IPV and emotional IPV was associated with attending a women's group, more childhood trauma, husband cruelty, her husband having more than one wife, experiencing other forms of family violence, more inequitable community gender norms, and greater reported disability. Emotional IPV and physical IPV were independently associated with worse health outcomes. IPV remains common in Afghanistan. Economic interventions for women alone are unlikely to prevent IPV and potentially may increase IPV. Economic interventions need to also work with husbands and families, and work to transform community level gender norms. NCT03236948 . Registered 28 July 2017, retrospectively registered.

Objective Despite increased attention to the relation between negative social reactions to intimate partner violence (IPV) disclosure and poorer mental health outcomes for victims, research has yet to examine whether certain types of negative social reactions are associated with poorer mental health outcomes more so than others. Further, research is scarce on potential mediators of this relationship. To fill these gaps, the current study examines whether stigmatizing reactions to IPV disclosure, such as victim-blaming responses and minimizing experiences of IPV, are a specific type of negative social reaction that exerts greater influence on women’s depressive symptoms than general negative reactions, such as being angry at the perpetrators of IPV. We also examine avoidance coping as a key mediator of this relationship. Methods A cross sectional correlational study was conducted to examine these relationships. Participants were 212 women from an urban northeast community who indicated being physically victimized by their male partner in the past six months. Results Findings from a multiple regression analysis showed that stigmatizing reactions, not general negative reactions, predicted women’s depressive symptoms. In addition, a multiple mediation analysis revealed that avoidance coping strategies, but not approach coping strategies, significantly accounted for the relationship between stigmatizing social reactions and women’s depressive symptoms. Conclusions Findings have implications for improving support from informal and formal sources and subsequently, IPV exposed women’s psychological well-being. PMID:27296052

DIFFERENT TYPES OF INTIMATE PARTNER VIOLENCE LIKELY REQUIRE DIFFERENT TYPES OF APPROACHES TO PREVENTION: A RESPONSE TO BUZAWA AND BUZAWA

Buzawa and Buzawa (this issue) assert that there are different typologies of intimate partner violence (IPV) defined by the extent to which the violence is part of a general pattern of coercive control. They center their discussion on batterers, who are understood to be responsible for the most severe forms of abuse and injury. Economic factors are believed to be “only a weak predictor of violence” in these cases. Thus, they argue that, in the face of severe budget constraints, there is a need to focus on the chronically violent offender and support-coordinated services for IPV victims. We agree that there are different types of IPV distinguishable by the extent to which the violence is occurring within a pattern of general coercive control and that each type has different risk and protective factors. We also agree economic factors interact with other factors in complex ways and vary in the extent to which they predict different types of IPV. However, we argue economic factors should not be ignored as an important strategy in preventing situational couple violence (SCV) and helping victims to escape from intimate terrorists (ITs). Relying on response (rather than prevention) strategies, such as coordinated community response—for which there is limited evidence of effectiveness—is unlikely to significantly impact rates of all types of IPV.

HIV prevention efforts promote the use of condoms to prevent the spread of HIV and other STDs. Thus, a woman's agency to practice healthy sexual behaviors necessarily involves negotiation with another person. This poses unique challenges for women who have limited power in relationships. The current study explores how the experience of intimate partner violence (IPV) impacts a woman's confidence in her ability to negotiate condom use with a sexual partner (i.e., condom use self-efficacy), using data from incarcerated females in three states, who were interviewed just prior to release back into the community. The direct effect of experiencing IPV as an adult, controlling for other risk factors, on condom use self-efficacy has not previously been empirically tested. Results show that IPV experiences among women significantly decreases their confidence in negotiating condom use with a partner, putting them at a higher risk of HIV infection than women who do not report having recently experienced IPV.

Nuanced, multifaceted, and content valid diagnostic criteria for intimate partner violence (IPV) have been created and can be used reliably in the field even by those with little-to-no clinical training/background. The use of such criteria such as these would likely lead to more reliable decision making in the field and more consistency across studies. Further, interrater agreement was higher than that usually reported for individual mental disorders. This paper will provide an overview of (a) IPV's scope and impact; (b) the reliable and valid diagnostic criteria that have been used and the adaptation of these criteria inserted in the latest Diagnostic and Statistical Manual of Mental Disorders (DSM) and another adaptation proposed for the forthcoming International Statistical Classification of Diseases and Related Health Problems (ICD); (c) suggestions for screening of IPV in primary care settings; (d) interventions for IPV; and (e) suggested steps toward globally accepted programs. © 2015 Family Process Institute.

The authors examined the relations among intimate partner violence (IPV), maternal depressive symptoms, and maternal harsh intrusive parenting. Using a cross-lagged, autoregressive path model, they sought to clarify the directionality of the relations among these 3 variables over the first 2 years of the child’s life. The results indicated that, in this diverse sample of families living in predominantly low-income rural communities (N = 705), higher levels of early IPV were associated with increases in maternal depressive symptoms, which in turn were associated with increases in maternal harsh intrusive parenting behaviors. These findings suggest that interventions aimed at improving the parenting of women exposed to domestic violence may want to simultaneously target IPV and depressive symptomatology. PMID:23869110

The objective of this study was to determine if a relationship exists between intimate partner violence (IPV) and HIV risk among socioeconomically disadvantaged Chilean women. A correlational analysis with data from the NIH-funded project, “Testing an HIV/AIDS Prevention Intervention for Chilean Women,” was conducted. Two hundred and sixtyone women were included in this analysis (n = 261). Those women who had experienced any type of IPV in the past 3 months had significantly higher risk for HIV than those who had not (t = −2.016, p < .05). Also a linear trend was found among those women who had experienced more than one type of IPV in the past 3 months and HIV risk. PMID:21486859

The objectives of this study were to identify the prevalence of past-year intimate partner violence (IPV) among women Veterans utilizing Veterans Health Administration (VHA) primary care, and to document associated demographic, military, and primary care characteristics. This was a retrospective cohort design, where participants completed a telephone survey in 2012 (84% participation rate); responses were linked to VHA administrative data for utilization in the year prior to the survey. A national stratified random sample of 6,287 women Veteran VHA primary care users participated in the study. Past-year IPV was assessed using the HARK screening tool. Self-report items and scales assessed demographic and military characteristics. Primary care characteristics were assessed via self-report and VHA administrative data. The prevalence of past-year IPV among women Veterans was 18.5% (se = 0.5%), with higher rates (22.2% - 25.5%) among women up to age 55. Other demographic correlates included indicators of economic hardship, lesbian or bisexual orientation, and being a parent/guardian of a child less than 18 years old. Military correlates included service during Vietnam to post-Vietnam eras, less than 10 years of service, and experiences of Military Sexual Trauma (MST). Most (77.3%, se = 1.2%) women who experienced IPV identified a VHA provider as their usual provider. Compared with women who did not report past-year IPV, women who reported IPV had more primary care visits, yet experienced lower continuity of care across providers. The high prevalence of past-year IPV among women beyond childbearing years, the majority of whom primarily rely on VHA as a source of health care, reinforces the importance of screening all women for IPV in VHA primary care settings. Key considerations for service implementation include sensitivity with respect to sexual orientation, race/ethnicity, and other aspects of diversity, as well as care coordination and linkages with social services and MST-related care.

Social norms increasingly are the focus of intimate partner violence (IPV) prevention strategies but are among the least examined contextual factors in quantitative violence research. This study assesses the within-community, between-community, and contextual effect of a new measure of social norms (PVNS: Partner Violence Norms Scale) on women's risk of IPV. Data come from baseline surveys collected from 1435 female, married, reproductive-age participants, residing in 72 wards in three districts (Chitwan, Kapilvastu, Nawalparasi) in Nepal who were enrolled in a cluster randomized trial testing the impact of a social behavioral change communication intervention designed to prevent IPV. Results of unconditional multilevel logistic regression models indicated that there was cluster-level variability in the 12-month prevalence of physical (ICC = 0.07) and sexual (ICC = 0.05) IPV. Mean PVNS scores also varied across wards. When modeled simultaneously, PVNS scores aggregated to the ward-level and at the individual-level were associated with higher odds of physical (OR ind  = 1.12, CI = 1.04, 1.20; OR ward  = 1.40, CI = 1.15, 1.72) and sexual (OR ind  = 1.15, CI = 1.08, 1.24; OR ward  = 1.47, CI = 1.24, 1.74) IPV. The contextual effect was significant in the physical (0.23, se = 0.11, t = 2.12) and sexual (0.24, se = 0.09, t = 2.64) IPV models, suggesting that the ward-level association was larger than that at the individual-level. Adjustment for covariates slightly attenuated the ward-level association and eliminated the contextual association, suggesting that individual perceptions and the collective community phenomena were equally strong predictors of women's risk of IPV and should be taken into consideration when planning interventions. PVNS is a promising measure of social norms underpinning women's risk of IPV and warrants further psychometric testing. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

Intimate partner violence (IPV) has myriad negative health and economic consequences for women and families. We hypothesized that empowering women through a combination of formal business training, microfinance, and IPV support groups would decrease IPV and improve women's economic status. The study included adult female survivors of severe IPV. Women living in Korogocho received the intervention and women in Dandora served as a standard of care (SOC) group, but received the intervention at the end of the follow-up period. Women in the intervention groups ( n = 82, SOC group, n = 81) received 8 weeks of business training, assistance creating a business plan, a small initial loan (about US$60), and weekly business and social support meetings. The two primary outcome measures included change in: (a) average daily profit margin, and (b) incidence of severe IPV. Exploratory analysis also looked at incidence of violence against children and women's self-efficacy. Average daily profit margin in the intervention group increased by 351 Kenyan Shillings (about US$3.5) daily (95% CI = [172, 485]). IPV directed against participating women decreased from a baseline of 2.1 to 0.26 incidents, a difference of 1.84 incidents (95% CI = [1.32, 2.36]). Violence against children in the household in the prior 3 months decreased from 1.1 to 0.55 incidents, a difference of 0.55 incidents (95% CI = [0.16, 1.03]). Finally, the intervention appears to have increased self-efficacy scores by 0.42 points (95% CIs 0.13, 0.71). In a low-resource urban environment, employing three complementary interventions resulted in higher daily profit margins and lower IPV in the intervention compared with the SOC group. These data support the notion that employing multiple interventions concomitantly might possess synergistic, beneficial effects, and hold promise to address profound poverty and interrupt the devastating cycle of IPV.

Background Interpersonal violence (IPV) is associated with higher risk of depression. Female Chinese rural-to-urban migrants may experience greater depression following exposure to IPV due to lack of social support and integration within their receiving communities. The current study estimated the prevalence of IPV among rural-to-urban migrants in Guangzhou, China, and evaluated the moderating effects of social resources on migrant's depression symptoms. Method We recruited 1,368 women (1,003 migrants and 365 local-born) of childbearing age from population and family planning centers in two districts using a quota sampling method matched to the 2012 population census. Chinese versions of the Conflict Tactics Scale 2 Short Form, Center for Epidemiological Studies Depression Scale and the Social Support Rating Scale measured IPV, depression, and social support. Social integration was measured with a locally derived scale. Results Migrants reported a similar prevalence for IPV (41.20%) to local women (39.20%). Bivariate comparisons demonstrated that migrants reported greater depression (11.8±8.9 vs. 10.0±8.8, t=−3.27, p<0.001) and less social support (22.2±5.1 vs. 27.1±5.5, t=14.84, p<0.001). Regression analysis indicated that the effect of violence on depression symptoms for migrant women was moderated by social integration. Women who experienced violence and had greater integration in their community reported less depression than women who experienced violence but reported less social integration. Conclusion A high prevalence of IPV was reported in our sample. Social integration is a key risk factor for migrant mental health. Social services aimed to reduce IPV and integrate migrants in their new communities are needed. PMID:25511732

Child marriage and intimate partner violence: a comparative study of 34 countries.

: Studies in South Asia suggest that child marriage is a strong risk factor for intimate partner violence (IPV), but evidence outside the region is lacking. : This study uses standardized data from demographic and health surveys in 34 countries to test the hypothesis that young women (age 20-24) who married as children are at increased risk of past year physical and/or sexual IPV as compared with those women who married as adults. : Globally, 9% of respondents were married before they turned 15; another 25% were married between the ages of 15 and 17. Past year physical and/or sexual IPV was higher among women who married as children (29%) compared with those who married as adults (20%). This difference persisted in logistic regression models that adjust for sociodemographic characteristics [odds ratio (OR) 1.41 (1.30-1.52) for marriage before 15, and 1.42 (1.35-1.50) for marriage at 15-17]. However, there was considerable heterogeneity between countries: marriage before age 15 was associated with a combined measure of past year physical and/or sexual IPV in nine countries; women married between 15 and 17 were at increased risk of physical and/or sexual IPV in 19 countries. This heterogeneity was most evident in sub-Saharan Africa, and warrants further investigation in so far as it may help identify protective policies and norms. : Substantial reductions in IPV will likely require interventions to combat child marriage itself and to protect women from IPV within child marriages. © The Author 2016; all rights reserved.

Child marriage (before age 18) is a risk factor for intimate partner violence (IPV) against women. Worldwide, Bangladesh has the highest prevalence of IPV and very early child marriage (before age 15). How the community prevalence of very early child marriage influences a woman’s risk of IPV is unknown. Using panel data (2013–2014) from 3,355 women first married 4–12 years prior in 77 Bangladeshi villages, we tested the protective effect of a woman’s later first marriage (at age 18 or older), the adverse effect of a higher village prevalence of very early child marriage, and whether any protective effect of a woman’s later first marriage was diminished or reversed in villages where very early child marriage was more prevalent. Almost one-half (44.5 %) of women reported incident physical IPV, and 68.9 % had married before age 18. The village-level incidence of physical IPV ranged from 11.4 % to 75.0 %; the mean age at first marriage ranged from 14.8 to 18.0 years. The mean village-level prevalence of very early child marriage ranged from 3.9 % to 51.9 %. In main-effects models, marrying at 18 or later protected against physical IPV, and more prevalent very early child marriage before age 15 was a risk factor. The interaction of individual later marriage and the village prevalence of very early child marriage was positive; thus, the likely protective effect of marrying later was negated in villages where very early child marriage was prevalent. Collectively reducing very early child marriage may be needed to protect women from IPV. PMID:27812927

Intimate partner violence (IPV) and unintended pregnancy are public health issues that can affect the health and well-being of women and their children. However, the relationship between IPV and women's ability to control their fertility has not been adequately explored. To investigate the association between unintended pregnancy and emotional or physical violence perpetrated by partners around pregnancy. A population-based study was undertaken, recruiting women (n=779) at the hospital obstetric departments and gathering social and family data. IPV was diagnosed by using the Index of Spouse Abuse (ISA). Data were gathered by trained midwives in 15 public hospitals in southern Spain and multivariate logistic regression analysis was performed. The pregnancy was reported to be unintended by 118 (15.1%) of the study population. Unintended pregnancy was significantly associated with: physical and/or emotional IPV around pregnancy, age, marital status, cohabitation, educational level, and employment status. After adjusting for socio-demographic characteristics, emotional IPV around pregnancy was significantly associated with an unintended pregnancy (AOR=2.5; 95% CI=1.5-4.3). Being in a non-committed relationship was a risk factor (AOR=3.5; 95% CI=1.8-6.1) and being in employment a protective factor (AOR=0.4; 95% CI=0.2-0.8) for an unintended pregnancy. Women who report an unintended pregnancy may be experiencing emotional IPV. The risk of emotional IPV is higher if women reporting an unintended pregnancy are in a committed relationship, married, or in employment. A better understanding of the relationship between unintended pregnancy and violence can aid midwives about potential reproductive health risk factors associated with abuse.

Recent research suggests that men who have sex with men (MSM) experience intimate partner violence (IPV) at significantly higher rates than heterosexual men. Few studies, however, have investigated implications of heterosexist social pressures - namely, homophobic discrimination, internalized homophobia, and heterosexism - on risk for IPV among MSM, and no previous studies have examined cross-national variations in the relationship between IPV and social pressure. This paper examines reporting of IPV and associations with social pressure among a sample of internet-recruited MSM in the United States (U.S.), Canada, Australia, the United Kingdom, South Africa, and Brazil. We recruited internet-using MSM from 6 countries through selective banner advertisements placed on Facebook. Eligibility criteria were men age over 18 reporting sex with a man in the past year. Of the 2,771 eligible respondents, 2,368 had complete data and were included in the analysis. Three outcomes were examined: reporting recent experience of physical violence, sexual violence, and recent perpetration of physical violence. The analysis focused on associations between reporting of IPV and experiences of homophobic discrimination, internalized homophobia, and heteronormativity. Reporting of experiencing physical IPV ranged from 5.75% in the U.S. to 11.75% in South Africa, while experiencing sexual violence was less commonly reported and ranged from 2.54% in Australia to 4.52% in the U.S. Perpetration of physical violence ranged from 2.47% in the U.S. to 5.76% in South Africa. Experiences of homophobic discrimination, internalized homophobia, and heteronormativity were found to increase odds of reporting IPV in all countries. There has been little data on IPV among MSM, particularly MSM living in low- and middle-income countries. Despite the lack of consensus in demographic correlates of violence reporting, heterosexist social pressures were found to significantly increase odds of reporting IPV in all countries. These findings show the universality of violence reporting among MSM across countries, and highlight the unique role of heteronormativity as a risk factor for violence reporting among MSM. The results demonstrate that using internet-based surveys to reach MSM is feasible for certain areas, although modified efforts may be required to reach diverse samples of MSM.

Spousal age difference and associated predictors of intimate partner violence in Nigeria.

The growth in Intimate Partner Violence (IPV) cases among couples in Nigeria has been significant in recent years. Victims, which are often females, face numerous health challenges, including early death. I examined the linkages between spousal age differences and IPV in Nigeria. The couples recode data section of the 2013 Nigeria Demographic Health and Survey was used (n = 6765). Intimate partner violence was measured using 13-item questions. Data were analyzed using the logistic regression model (α = .05). The mean spousal age difference was 8.20 ± 5.0 years. About 23.5, 18.0, 13.5 and 4.7% of couples surveyed had experienced some form of IPV, emotional, physical and sexual violence respectively. Also, IPV prevalence was 27.0, 23.7, 22.0 and 18.7% among couples with age differences of 0-4, 5-9, 10-14 and ≥15 years respectively; this pattern was exhibited across all domains of IPV. Among women who experienced physical violence, 20.5% had only bruises, 8.0% had at least one case of eye injuries, sprains and/or dislocations, and 3.7% had either one or more cases of wounds, broken bones or broken teeth. The identified predictors of IPV were: family size, ethnicity, household wealth, education, number of marital unions and husband drinks alcohol. The unadjusted likelihood of IPV was 1.60 (C.I = 1.30-1.98, p < 0.001) and 1.35 (C.I = 1.10-1.64, p < 0.01) higher in households where the spousal age difference was 0-4 and 5-9 years respectively, than the likelihoods among those with a spousal age difference ≥ 15 years, but the strength of the association weakens when other variables were included in the model. The level of IPV was generally high in Nigeria, but it reduced with increasing spousal age difference. This study underscores the need for men to reach a certain level of maturity before marriage, as this is likely to reduce the level of IPV in Nigeria.

Women who experience intimate partner violence (IPV) often do not perceive themselves as abused. This study sought to estimate the health effects of unperceived IPV (uIPV), taking violence-free women as the reference, and to compare the effects of uIPV with those of perceived IPV (pIPV). We performed a cross-sectional population study through telephone interviews of 2835 women aged 18 to 70 years living in the region of Madrid and having an ongoing intimate partner relationship or contact with a former partner in the preceding year. Based on 26 questions from the Conflict Tactics Scale-1 and the Enquête Nacional sur les Violences envers les Femmes en France and the question "Do you feel abused by your partner?" a variable was constructed in three categories, namely, the absence of IPV, uIPV and pIPV. Using logistic regression, we analyzed the association between health problems, medication use, health-service utilization and IPV (perceived and unperceived) vis-à-vis the absence of IPV. There were 247 cases of uIPV and 96 of pIPV (prevalences of 8.8% and 3.4%, respectively). The multivariate analysis showed that a substantial number of the outcomes explored were associated with uIPV, pIPV, or both. The highest odds ratios (ORs) were obtained for depression (Patient Health Questionnaire-9≥10) (uIPV: OR 3.4, 95% CI 2.4-3.8; and pIPV: 4.1, 95%CI 2.5-6.8). In most problems, the ORs did not significantly differ between the two types of IPV. uIPV is 2.6 times more frequent than pIPV and is associated with at least as many health problems as pIPV.

Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruption. Mobile IPv6 was proposed to provide mobility support to IPv6-based mobile nodes for continuous communication when they roam across different networks. However, the Route Optimization procedure in Mobile IPv6 involves the verification of mobile node's reachability at the home address and at the care-of address (home test and care-of test) that results in higher handover delays and signalling overhead. This paper presents an enhanced procedure, time-based one-time password Route Optimization (TOTP-RO), for Mobile IPv6 Route Optimization that uses the concepts of shared secret Token, time based one-time password (TOTP) along with verification of the mobile node via direct communication and maintaining the status of correspondent node's compatibility. The TOTP-RO was implemented in network simulator (NS-2) and an analytical analysis was also made. Analysis showed that TOTP-RO has lower handover delays, packet loss, and signalling overhead with an increased level of security as compared to the standard Mobile IPv6's Return-Routability-based Route Optimization (RR-RO).

Evidence on the relationship between maternal depression and exposure to intimate partner violence (IPV) with child physical growth and development is equivocal. Our aim in the current study is to examine these relationships among women and their children in Tanzania. The Bayley Scales of Infant Development and anthropometric measures were used to assess children 18 to 36 months of age ( n = 1031). Maternal exposure to IPV and depression were assessed using the Tanzania Demographic and Health Survey questionnaire and the Patient Health Questionnaire-9, respectively. We used linear regression models to calculate standardized mean differences (SMDs) for developmental outcomes and generalized linear models to estimate the associations with nutritional status. Mild depressive symptoms in mothers (Patient Health Questionnaire-9 ≥5) and exposure to physical and sexual IPV were associated with lower SMDs for motor skills (-0.14 [ P = .023] and -0.23 [ P < .01], respectively), expressive communication (-0.13 [ P = .187] and -0.23 [ P < .01], respectively), receptive communication (-0.19 [ P < .009] and -0.16 [ P = .03], respectively), and cognitive development (-0.08 [ P = .245] and -0.12 [ P = .07], respectively). Exposure to physical and sexual IPV was associated with higher risk for stunting (relative risk = 1.6; P < .001). This study reveals that maternal depressive symptoms and IPV are associated with adverse child nutritional and developmental outcomes. Further research is needed to develop programs to address IPV and depression among women and enhance the growth and development of their children.

Intimate Partner Violence (IPV) perpetration may induce cardiovascular reactivity and risk markers thereby precipitating early onset cardiovascular disease (CVD). However, this relationship has been largely under-researched in comparison to the health impacts of IPV victimisation. We therefore aimed to systematically review the current evidence investigating the relationship between IPV perpetration and CV risk. Six databases (CINAHL, Ovid MEDLINE, Pubmed, Scopus, ProQuest, Google Scholar) were searched between August 2016 and August 2017 using a predefined search strategy. Inclusion criteria were studies of cross sectional and longitudinal design published since 2010, presenting IPV status by perpetrators (as distinct from victims) and an outcome of CVD (e.g. cardiac disease, stroke), CV risk markers (e.g. blood pressure) and/or a composite CV risk score. Twenty two potentially eligible studies were identified and full texts recovered. After ineligible studies were excluded, four remained (total n = 10,665). Positive relationships were observed between IPV perpetration and (i) short term CV reactivity markers (higher heart rate, lower vagal ratios, shorter pre-ejection periods) and (ii) longer term CV risk factors and outcomes including greater systolic blood pressure, incident hypertension, elevated 30 year CV risk score and self-report cardiac disease. Despite being a neglected area of research characterised by a high degree of heterogeneity, the early evidence suggests that IPV perpetration may be associated with elevated risk of CVD. We discuss these findings in the context of CVD prevention from the individual, family and inter-generational perspectives and directions for future studies.

Background Little knowledge exists in Mozambique and sub-Saharan Africa about the mental health (symptoms of depression, anxiety, and somatization) of women victims and perpetrators of intimate partner violence (IPV) by type of abuse (psychological aggression, physical assault without/with injury, and sexual coercion). This study scrutinizes factors associated with mental health among women victims and perpetrators of IPV over the 12 months prior to the study. Methods and materials Mental health data were analyzed with bivariate and multiple regression methods for 1442 women aged 15–49 years who contacted Forensic Services at Maputo Central Hospital (Maputo City, Mozambique) for IPV victimization between April 1, 2007 and March 31, 2008. Results In bivariate analyses, victims and perpetrators of IPVs scored higher on symptoms of mental health than their unaffected counterparts. Multiple regressions revealed that controlling behaviors, mental health comorbidity, social support, smoking, childhood abuse, sleep difficulties, age, and lack of education were more important in explaining symptoms of mental health than demographics/socioeconomics or life-style factors. Victimization and perpetration across all types of IPV were not associated with symptoms of mental health. Conclusion In our sample, victimization and perpetration were not important factors in explaining mental ill health, contrary to previous findings. More research into the relationship between women’s IPV victimization and perpetration and mental health is warranted as well as the influence of controlling behaviors on mental health.

There are many studies concerning the health consequences of intimate partner violence (IPV). However, little research has been done on the health consequences of other forms of violence against women (VAW) such as the violence perpetrated by male relatives, friends or strangers. The aims of this paper were: (i) to analyze the prevalence of different forms of VAW perpetrated by males at home, workplace and other social environments in Spain and (ii) to analyze whether IPV and other forms of VAW have a different or similar negative impact on women's health. A sample of 13 094 women interviewed in the Spanish National Health Survey 2006 was included. Outcomes were physical and mental health indicators. Predictor variables were IPV and other VAW forms. Logistic regression models were fitted. The likelihood of coronary heart disease [OR: 5.28 (1.45-19.25)], chronic neck [OR: 2.01 (1.35-2.97)] and back pain [OR: 2.34 (1.53-3.57)] was higher among women who reported IPV than among those who did not. Similar associations were found in the case of women affected by other forms of VAW. Mental health problems, with the exception of psychotropic drug use, were more frequent and more strongly associated with IPV than with other forms of VAW. There are health inequities between battered and non-battered women, which may be related to exposure to not only IPV but also other forms of VAW.

Gendered Social Learning, Nonfamily Institutions, and Attitudes About Recourse After Partner Violence.

To provide the first study in Vietnam of how gendered social learning about violence and exposure to non-family institutions influence women's attitudes about a wife's recourse after physical IPV. A probability sample of 532 married women, ages 18-50 years, was surveyed in July-August, 2012 in Mỹ Hào district. We fit a multivariate linear regression model to estimate correlates of favoring recourse in six situations using a validated attitudinal scale. We split attitudes towards recourse into three subscales (disfavor silence, favor informal recourse, favor formal recourse) and fit one multivariate ordinal logistic regression model for each behavior to estimate correlates of favoring recourse. On average, women favored recourse in 2.8 situations. Women who were older and had witnessed physical IPV in childhood had less favorable attitudes about recourse. Women who were hit as children, had completed more schooling, worked outside agriculture, and had sought recourse after IPV had more favorable attitudes about recourse. Normative change among women may require efforts to curb family violence, counsel those exposed to violence in childhood, and enhance women's opportunities for higher schooling and non-agricultural wage work. The state and organizations working on IPV might overcome pockets of unfavorable public opinion by enforcing accountability for IPV rather than seeking to alter ideas about recourse among women.

Male Perpetrators of Intimate Partner Violence and Implicit Attitudes toward Violence: Associations with Treatment Outcomes

The present study examined the associations among implicit attitudes toward factors related to intimate partner violence (IPV) and objective, behavioral outcomes of participants legally mandated to attend partner violence interventions. Twenty-six male offenders, adjudicated within the past month on IPV charges, completed three sets of gender and violence themed implicit associations tests (IATs) to evaluate the relationships between implicit evaluations of women and violence and three key outcome measures assessed six months after enrollment in the study: self-reported prior year IPV perpetration, completion of a court-mandated partner abuse program, and criminal reoffending. IAT results indicated that more rapid associations between violence-related words and positive valences, rather than gender evaluations or associations between gender and violence, were associated with greater IPV perpetration during the year prior to involvement in the study as well as with poorer outcomes (i.e., greater treatment non-compliance and criminal recidivism) at the 6-month follow-up. Among explicit measures, only negative partner violence outcome expectancies were marginally associated with treatment compliance. None of the explicit measures predicted previous violence or recidivism. The findings are discussed in the context of reducing violence through promoting implicit cognitive change. PMID:25598562

Psychological Predictors of Sexual Intimate Partner Violence against Black and Hispanic Women

Preiser, Brianna

2017-01-01

Background: Although various types of intimate partner violence (IPV) tend to co-occur, risk factors of each type of IPV may differ. At the same time, most of the existing literature on risk factors of IPV among minorities has used a cross-sectional design and has focused on physical rather than sexual IPV. We conducted the current study to compare Black and Hispanic women for psychological predictors of change in sexual IPV over time. Methods: Using data from the Fragile Families and Child Wellbeing Study (FFCWS), this study followed 561 Black and 475 Hispanic women with their male partners for four years. Independent variables included male partners’ depression, anxiety, problem alcohol use, and male-to-female physical and psychological IPV perpetration. The dependent variable was sexual IPV reported by female partners, measured at baseline, two years, and four years later. Covariates included age, income, marital status and education level. We used a multi-group latent growth curve model (LGCM) to explain intercept, linear, and quadratic slopes, which represent the baseline, and linear and curvilinear trajectories of male-to-female sexual IPV, where groups were defined based on ethnicity. Results: Psychological IPV was associated with sexual IPV at baseline among both ethnic groups. The male partner’s depression was a risk factor for an increase in sexual IPV over time among Black but not Hispanic women. Anxiety, problem alcohol use and physical IPV did not have an effect on the baseline or change in sexual IPV over time. Psychological IPV was not associated with an increase in sexual IPV over time in either ethnic group. Conclusions: There is a need for screening of sexual IPV in the presence of psychological IPV among minority women. There is also a need for screening and treatment of male partners’ depression as a strategy to reduce sexual IPV among Black women.

Intimate partner violence (IPV) may interfere with women's use of preferred forms of contraception, resulting in unwanted pregnancies forcing women to seek permanent sterilization. A history of child sexual abuse (CSA) presages the risk for IPV in adulthood setting the stage for adverse reproductive outcomes. To determine whether CSA and IPV are associated with women's voluntary sterilization when adjusting for demographics and reproductive health history. This cross-sectional study is based on in-person interviews of women (N = 278) drawn from outpatients surveyed in more than 10 different clinics (N = 2465). Women's history of gender-based violence and bilateral tubal ligation (BTL) were assessed. About half of the women had a past history of IPV and 29% disclosed CSA. CSA predicted later entry into an abusive relationship (odds ratio [OR] = 6.7). Sterilization was reported by 19.6%. Parity (3+ children), having had an abortion, and receipt of welfare were associated with sterilization in univariate tests. Among those women receiving a BTL, 74% had violent partners. Adjusted multivariate logistic regressions, adjusted for demographics and reproductive history, indicated that having had an abusive partner increased the odds of sterilization; parity was also highly associated. CSA exerted only an indirect influence on sterilization via entry into violent relationships. IPV raises the likelihood that women will choose sterilization. Despite the importance of women's access to permanent contraception, priority should be given to screening for gender-based violence and promoting interventions.

Shifting Perceptions of Consequences of IPV Among Beneficiaries of Indashyikirwa: An IPV Prevention Program in Rwanda.

2018-06-01

Indashyikirwa is a Rwandan program that seeks to prevent intimate partner violence (IPV) and support healthy, equitable relationships. A fundamental program aspect is a 5-month curriculum among heterosexual couples designed to identify the causes and consequences of economic, emotional, physical, and sexual IPV, and build skills to manage triggers of IPV. The program also trained opinion leaders to more effectively prevent and respond to IPV, and established women's safe spaces to educate women about their rights, refer or accompany women who wish to report abuse or seek services. Drawing on 30 interviews with couples and 9 interviews with opinion leaders before and after completing the Indashyikirwa trainings, this article highlights beneficiaries' perceived consequences of IPV, and how such perceptions were influenced through the Indashyikirwa program. Interviews were conducted in Kinyarwanda, recorded, translated, and transcribed into English and analyzed thematically. The data reveal a depth of understanding of consequences of various forms of IPV. Although several participants justified more minor forms of men's physical IPV, such as slapping, severe consequences of physical IPV were most readily identified and sanctioned. Various harms of emotional and economic IPV were reported, yet these forms of IPV were typically less socially sanctioned or identified as IPV. Conceptions of sexual IPV were influenced by inequitable gender norms, and not typically recognized as a violation under the law. Although the data do not yet demonstrate the long-term impact, collectively identifying the overlapping consequences and underlying power inequalities for all forms of IPV, the legal rights protecting against various forms of IPV, and the benefits of nonviolent, equitable relationships, appeared to be helpful to shift perceptions of consequences of IPV. Implications of the findings for the program and broader IPV prevention are identified.

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors. Analyses were conducted at the couple level, with IPV groups as a between-subjects couple level variable and sex as a within-subjects variable that allowed us to model and compare the outcomes of both partners while controlling for the correlated nature of the data. Analyses controlled for age, race, income, relationship duration, and gestational age. Among couples, 64% had no IPV; 23% male IPV victim only; 7% mutual IPV; 5% female IPV victim only. Relationship (F = 3.61, P < .001) and psychological (F = 3.17, P < .001) factors differed by IPV group, overall. Attachment anxiety, attachment avoidance, relationship equity, perceived partner infidelity, depression, stress, and hostility each differed by IPV profile (all P < .01). Attachment anxiety, equity, depression and stress had a significant IPV profile by sex interaction (all P < .05). Couples with mutual IPV had the least healthy relationship and psychological characteristics; couples with no IPV had the healthiest characteristics. Females in mutually violent relationships were at particularly high risk. Couple-level interventions focused on relational issues might protect young families from developing IPV behaviors.

The WomanKind program, a non-profit health care based program for for victims of domestic/intimate partner violence (IPV), seeks to enable and motivate health care providers to identify victims of such violence and refer them to WomanKind's in-house services. An evaluation designed to assess client referral to WomanKind services and the impact of health care provider training was carried out. Data were collected at three intervals over a 2-year period at 3 intervention and 2 comparison hospitals located in Minneapolis, MN. The focus of data collection efforts was to assess the providers' knowledge, attitudes, beliefs, and behaviors (KABB) concerning identification and referral of victims of IPV. Hospital staff and volunteer advocate training programs also were evaluated. Chart reviews were conducted and client referrals assessed. Providers at WomanKind hospitals demonstrated significantly higher knowledge, attitudes, beliefs and behaviors than those at comparison hospitals throughout the study. During the data collection period, 1719 IPV victims were identified and referred to the WomanKind program, while only 27 IPV victims were referred to trained social workers at the comparison hospitals. Chart reviews indicated that emergency staff at the intervention sites provide documentation of IPV in patient records twice as frequently as emergency staff at the comparison sites. This research underscores the efficacy of a well-structured, multidisciplinary effort to deliver services to IPV victims. The results demonstrate that specialized training and on-site client services create a significant positive impact on the KABB of health care providers.

Child Brides, Forced Marriage, and Partner Violence in America: Tip of an Iceberg Revealed.

Forced marriage is a violation of human rights and thwarts personal safety and well-being. Child brides are at higher risk of intimate partner violence (IPV) and often are unable to effectively negotiate safe sex, leaving them vulnerable to sexually transmitted infections, including human immunodeficiency virus, and early pregnancy. The prevalence of forced marriage and child marriage in the United States is unknown. The intersection of forced marriage and child marriage and IPV is equally unknown. When 277 mothers who reported IPV to shelter or justice services were asked about a forced marriage attempt, frequency and severity of IPV, mental health status, and behavioral functioning of their child, 47 (17%) reported a forced marriage attempt with 45% of the women younger than 18 years of age at the time of the attempt. Among the 47 women, 11 (23%) reported death threats, 20 (43%) reported marriage to the person, and 28 (60%) reported a pregnancy. Women younger than 18 years reported more threats of isolation and economic deprivation associated with the attempt as well as pressure from parents to marry. Regardless of age, women experiencing a forced marriage attempt reported more intimate partner sexual abuse, somatization, and behavior problems for their children. Forced marriage attempts occurred to one in six women (17%) reporting IPV and are associated with worse functioning for mother and child. The frequent occurrence and associated effect of forced marriage attempts to maternal child functioning indicates routine assessment for a forced marriage attempt as part of comprehensive care for women reporting IPV.

Not All Behind Closed Doors: Examining Bystander Involvement in Intimate Partner Violence.

Taylor, Elizabeth; Banyard, Victoria; Grych, John; Hamby, Sherry

2016-10-01

It is often said that intimate partner violence (IPV) happens "behind closed doors"; however, research on IPV and other crimes suggests that witnesses are sometimes present. This suggests that bystanders may be in a position to help victims or potential victims of violence. Bystander behavior has been studied primarily in school settings, and consequently, little is known about how often it occurs or what its effects may be in the broader community. This study examined IPV incidents in a rural sample to assess the presence and potential impact of bystanders on victim-reported outcomes. One thousand nine hundred seventy-seven adult participants completed a questionnaire that asked about five violent behaviors (my partner threatened to hurt me; pushed, grabbed, or shook me; hit me; beat me up; sexually assaulted me), bystander characteristics, and victim outcomes (fear; injury; disruption of daily routines; mental health). Adult or teen bystanders were present for each IPV approximately one third of the time, except in the case of sexual assault (14.3%). When a bystander was present, victims reported higher rates of injury, greater disruption in their routines, and poorer mental health. When a bystander's safety was threatened, victims reported more physical injury and more routine disruption. A considerable number of IPV incidents do not happen behind closed doors, and the presence of a bystander was associated with worse outcomes for victims. Prevention efforts for adult IPV may need to take a more cautious or nuanced approach to encouraging bystander action, especially when confronted with more severe incidents. Bystander safety should be a priority for violence prevention.

Performance evaluation of secured DICOM image communication with next generation internet protocol IPv6

Next Generation Internet (NGI) technology with new communication protocol IPv6 emerges as a potential solution for low-cost and high-speed networks for image data transmission. IPv6 is designed to solve many of the problems of the current version of IP (known as IPv4) with regard to address depletion, security, autoconfiguration, extensibility, and more. We choose CTN (Central Test Node) DICOM software developed by The Mallinckrodt Institute of Radiology to implement IPv6/IPv4 enabled DICOM communication software on different operating systems (Windows/Linux), and used this DICOM software to evaluate the performance of the IPv6/IPv4 enabled DICOM image communication with different security setting and environments. We compared the security communications of IPsec with SSL/TLS on different TCP/IP protocols (IPv6/IPv4), and find that there are some trade-offs to choose security solution between IPsec and SSL/TLS in the security implementation of IPv6/IPv4 communication networks.

Victim of and witness to violence: an interactional perspective on mothers' perceptions of children exposed to intimate partner violence.

2011-01-01

This article reports a study of how mothers perceive the effects of intimate partner violence (IPV) during pregnancy and children's exposure to IPV: (a) Do interactional aspects of IPV have a negative impact on the fetus during pregnancy or on the newborn baby? and (b) Is there a relationship between interactional aspects of IPV and (a) children's risk of being exposed to IPV and (b) the age of the child when at risk for exposure to IPV? A representative sample of 137 IPV help-seeking mothers in Norway was interviewed. Severity of physical IPV and injury from sexual IPV increased the risk of consequences to the fetus. Frequency of physical and psychological IPV increased the likelihood of children's exposure. Duration of the partnership increased the risk of children's exposure to physical and sexual IPV. Finally, there was a negative linear association between children's age when exposed for the first time and frequency of physical and psychological IPV.

Intimate partner violence among adolescents and young women: prevalence and associated factors in nine countries: a cross-sectional study.

Little is known about the prevalence of intimate partner violence (IPV) and its associated factors among adolescents and younger women. This study analyzed data from nine countries of the WHO Multi-country Study on Women's Health and Domestic Violence against Women, a population based survey conducted in ten countries between 2000 and 2004. The lifetime prevalence of IPV ranged from 19 to 66 percent among women aged 15 to 24, with most sites reporting prevalence above 50 percent. Factors significantly associated with IPV across most sites included witnessing violence against the mother, partner's heavy drinking and involvement in fights, women's experience of unwanted first sex, frequent quarrels and partner's controlling behavior. Adolescent and young women face a substantially higher risk of experiencing IPV than older women. Adolescence and early adulthood is an important period in laying the foundation for healthy and stable relationships, and women's health and well-being overall. Ensuring that adolescents and young women enjoy relationships free of violence is an important investment in their future.

Association of intimate partner violence and health-care provider-identified obesity.

2016-07-01

The association of physical and nonphysical intimate partner violence (IPV) with obesity was examined. Women (N = 1,179) were surveyed regarding demographics, obesity, and IPV exposure using humiliate-afraid-rape-kick (HARK), an IPV screening tool. A three-level lifetime IPV exposure variable measured physical, nonphysical or no IPV. Health-care provider-identified obesity was defined if participants were told by a medical provider within the past 5 years that they were obese. Bivariate analyses examined obesity by IPV and demographics. Multivariable logistic regression assessed odds of obesity by IPV type, adjusting for age, race/ethnicity, education, and marital status. Among participants, 44% reported lifetime IPV (25% physical, 19% nonphysical), and 24% reported health-care provider-identified obesity. In unadjusted analyses, obesity was more prevalent among women exposed to physical IPV (30%) and nonphysical IPV (27%), compared to women without IPV (20%, p = .002). In multivariable models, women reporting physical IPV had 1.67 times greater odds of obesity (95% confidence interval [CI] 1.20, 2.33), and women reporting nonphysical IPV had 1.46 times greater odds of obesity (95% CI 1.01, 2.10), compared to women reporting no exposure. This study extends prior data by showing, not only an association between physical IPV and obesity, but also an association between obesity and nonphysical IPV.

Cohabitation, referring to a co-residential romantic relationship between two intimate partners without a marriage license, has become widely accepted in contemporary societies. It has been found that cohabitating women have a higher risk of experiencing intimate partner violence (IPV) than married women. However, as yet, no studies have investigated the level and pattern of IPV-associated physical injuries and its mental health impact on cohabitating women. Therefore, we aim to compare IPV-associated physical injuries between cohabitating and married women by conducting a review of 5-year medical records from the emergency departments of two major public hospitals in Hong Kong. This is a retrospective cohort study. Using two computerized systems, we identified the medical charts of 1011 women who had experienced IPV and presented at emergency departments between 2010 and 2014, of which, 132 were cohabitating and 833 were married. Cohabitating women were significantly younger (p-value < .0001) and had obtained a higher educational level (p-value = .008) than married women. After adjusting for those two variables, the logistic regression models showed that cohabitating women were approximately 2.1 times more likely than married women to present with head, neck, or facial injuries (OR = 2.1, 95% CI = 1.30-3.40, p = .002), and the risk of having multiple injuries in different locations (head, neck, face, torso, limbs) was almost twice that for cohabitating women compared with married women (OR = 1.82, 95% CI = 1.25-2.65, p = .001). Furthermore, cohabitating women were almost two times as likely as married women to experience more than one method of physical violence (OR = 1.72, 95% CI = 1.18-2.51, p = .005). There were no significant differences regarding mental health, police reporting, and discharge plans. Owing to recent social changes to the family structure, including the growing acceptance of cohabitation, it is essential that a screening program for IPV is established for cohabitating women, as well as the inclusion of IPV content in medical and nursing curriculums and in-service training.

Bivalent oral poliovirus vaccine (bOPV; types 1 and 3) is expected to replace trivalent OPV (tOPV) globally by April, 2016, preceded by the introduction of at least one dose of inactivated poliovirus vaccine (IPV) in routine immunisation programmes to eliminate vaccine-associated or vaccine-derived poliomyelitis from serotype 2 poliovirus. Because data are needed on sequential IPV-bOPV schedules, we assessed the immunogenicity of two different IPV-bOPV schedules compared with an all-IPV schedule in infants. We did a randomised, controlled, open-label, non-inferiority trial with healthy, full-term (>2·5 kg birthweight) infants aged 8 weeks (± 7 days) at six well-child clinics in Santiago, Chile. We used supplied lists to randomly assign infants (1:1:1) to receive three polio vaccinations (IPV by injection or bOPV as oral drops) at age 8, 16, and 24 weeks in one of three sequential schedules: IPV-bOPV-bOPV, IPV-IPV-bOPV, or IPV-IPV-IPV. We did the randomisation with blocks of 12 stratified by study site. All analyses were done in a masked manner. Co-primary outcomes were non-inferiority of the bOPV-containing schedules compared with the all-IPV schedule for seroconversion (within a 10% margin) and antibody titres (within two-thirds log2 titres) to poliovirus serotypes 1 and 3 at age 28 weeks, analysed in the per-protocol population. Secondary outcomes were seroconversion and titres to serotype 2 and faecal shedding for 4 weeks after a monovalent OPV type 2 challenge at age 28 weeks. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01841671, and is closed to new participants. Between April 25 and August 1, 2013, we assigned 570 infants to treatment: 190 to IPV-bOPV-bOPV, 192 to IPV-IPV-bOPV, and 188 to IPV-IPV-IPV. 564 (99%) were vaccinated and included in the intention-to-treat cohort, and 537 (94%) in the per-protocol analyses. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroconversion to type 1 poliovirus were 166 (98·8%) of 168, 95% CI 95·8-99·7; 178 (100%), 97·9-100·0; and 175 (100%), 97·9-100·0. Proportions with seroconvsion to type 3 poliovirus were 163 (98·2%) of 166, 94·8-99·4; 177 (100%), 97·9-100·0, and 172 (98·9%) of 174, 95·9-99·7. Non-inferiority was thus shown for the bOPV-containing schedules compared with the all-IPV schedule, with no significant differences between groups. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroprotective antibody titres to type 1 poliovirus were 168 (98·8%) of 170, 95% CI 95·8-99·7; 181 (100%), 97·9-100·0; and 177 (100%), 97·9-100·0. Proportions to type 3 poliovirus were 166 (98·2%) of 169, 94·9-99·4; 180 (100%), 97·9-100·0; and 174 (98·9%) of 176, 96·0-99·7. Non-inferiority comparisons could not be done for this outcome because median titres for the groups receiving OPV were greater than the assay's upper limit of detection (log2 titres >10·5). The proportions of children seroconverting to type 2 poliovirus in the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, were 130 (77·4%) of 168, 95% CI 70·5-83·0; 169 (96·0%) of 176, 92·0-98·0; and 175 (100%), 97·8-100. IPV-bOPV schedules resulted in almost a 0·3 log reduction of type 2 faecal shedding compared with the IPV-only schedule. No participants died during the trial; 81 serious adverse events were reported, of which one was thought to be possibly vaccine-related (intestinal intussusception). Seroconversion rates against polioviruses types 1 and 3 were non-inferior in sequential schedules containing IPV and bOPV, compared with an all-IPV schedule, and proportions of infants with protective antibodies were high after all three schedules. One or two doses of bOPV after IPV boosted intestinal immunity for poliovirus type 2, suggesting possible cross protection. Additionally, there was evidence of humoral priming for type 2 from one dose of IPV. Our findings could give policy makers flexibility when choosing a vaccination schedule, especially when trying to eliminate vaccine-associated and vaccine-derived poliomyelitis.

Evaluating IPv6 Adoption in the Internet

NASA Astrophysics Data System (ADS)

Colitti, Lorenzo; Gunderson, Steinar H.; Kline, Erik; Refice, Tiziana

As IPv4 address space approaches exhaustion, large networks are deploying IPv6 or preparing for deployment. However, there is little data available about the quantity and quality of IPv6 connectivity. We describe a methodology to measure IPv6 adoption from the perspective of a Web site operator and to evaluate the impact that adding IPv6 to a Web site will have on its users. We apply our methodology to the Google Web site and present results collected over the last year. Our data show that IPv6 adoption, while growing significantly, is still low, varies considerably by country, and is heavily influenced by a small number of large deployments. We find that native IPv6 latency is comparable to IPv4 and provide statistics on IPv6 transition mechanisms used.

This study examined whether posttraumatic stress specifically resulting from intimate partner violence (IPV-related posttraumatic stress) mediated relationships between types of IPV and drug and alcohol problems among 212 women currently experiencing IPV. Six-month prevalence was high for drug use (48%) and alcohol use (59%). Structural equation modeling revealed that the frequency of physical, sexual, and psychological IPV were significantly and positively related to greater IPV-related posttraumatic stress, and IPV-related posttraumatic stress was significantly and positively related to drug problems. Further, IPV-related posttraumatic stress mediated the relationships between physical IPV and drug problems and psychological IPV and drug problems. Findings suggest that prevention and intervention efforts targeting posttraumatic stress among IPV-exposed women may reduce drug problems in this population.

If effective interventions are to be used to address child mortality and malnutrition, then it is important that we understand the different pathways operating within the framework of child health. More attention needs to be given to understanding the contribution of social influences such as intimate partner violence (IPV). To investigate the relationship between maternal exposure to IPV and child mortality and malnutrition using data from five developing countries. Population data from Egypt, Honduras, Kenya, Malawi and Rwanda were analysed. Logistic regression analysis was used to generate odds ratios of the associations between several categories of maternal exposure to IPV since the age of 15 and three child outcomes: under-2-year-old (U2) mortality and moderate and severe stunting (<-2 Z-score height-for-age and <-3 Z-score height-for-age) in 6-59-month-old children. Analyses were adjusted for potential confounders, and the role of mediating factors was explored. The prevalence of physical and/or sexual IPV since the age of 15 years ranged from 15.5% (Honduras) to 46.2% (Kenya). For child stunting, prevalence ranged from 25.4% (Egypt) to 58.0% (Malawi) and for U2 mortality from 3.6% (Honduras) to 15.2% (Rwanda). In Kenya, maternal exposure to IPV was associated with higher U2 mortality (adjusted odds ratio (OR)=1.42, 95% CI 1.18 to 1.71) and child stunting (adjusted OR=1.36, 95% CI 1.16 to 1.61). In Malawi and Honduras, marginal associations were observed between IPV and severe stunting and U2 mortality, respectively, with strength of associations varying by type of violence. The relationship between IPV and U2 mortality and stunting in Kenya, Honduras and Malawi suggests that, in these countries, IPV plays a role in child malnutrition and mortality. This contributes to a growing body of evidence that broader public health benefits may be incurred if efforts to address IPV are incorporated into a wider range of maternal and child health programmes; however, the authors highlight the need for more research that can establish temporality, use data collected on the basis of the study's objectives, and further explore the causal framework of this relationship using more advanced statistical analysis.

To determine demographics of children in homes to which police are called for intimate-partner violence (IPV) and to compare the relative risk of perpetrator versus victim for those who, as children, witnessed or were victims of IPV and sexual assault. Data from Resources, Inc. Victim Assistance Unit yearly intake statistics for 2004 were accessed. In this city with a population of approximately 500,000 people, police will call for an on-site advocate intervention (a trained social worker) at their own discretion for the adult or child victims of IPV and for children witnessing IPV. The social worker collects data on victims, perpetrators of IPV, and child witnesses or victims at all police calls for IPV. Comparisons were made by using chi-square, relative risks (RRs), and 95% confidence intervals (95% CI). Police and advocates visited 2,038 homes for IPV calls; 2,617 children were in these homes. Of these children, 1,904 (76%) witnessed IPV, and 698 (27%) were victims themselves. Adult victims (31%) and perpetrators (41%) had high rates of having witnessed IPV when they were children. Perpetrators were more likely than victims to have witnessed IPV as a child (RR, 1.56; 95% CI = 1.37 to 1.78) and to have been a victim of IPV as a child (RR, 1.71; 95% CI = 1.49 to 1.96). In this study population, 76% of IPV households include children, and one third of these children also are victims of IPV. Perpetrators often were victims and witnesses of IPV when they were children. This suggests that a history of childhood IPV is common for perpetrators of IPV. Development of and research on interventions for child witnesses or victims of IPV is needed.

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors. Analyses were conducted at the couple level, with IPV groups as a between-subjects couple level variable and sex as a within-subjects variable that allowed us to model and compare the outcomes of both partners while controlling for the correlated nature of the data. Analyses controlled for age, race, income, relationship duration, and gestational age. Among couples, 64% had no IPV; 23% male IPV victim only; 7% mutual IPV; 5% female IPV victim only. Relationship (F = 3.61, P < .001) and psychological (F = 3.17, P < .001) factors differed by IPV group, overall. Attachment anxiety, attachment avoidance, relationship equity, perceived partner infidelity, depression, stress, and hostility each differed by IPV profile (all P < .01). Attachment anxiety, equity, depression and stress had a significant IPV profile by sex interaction (all P < .05). Couples with mutual IPV had the least healthy relationship and psychological characteristics; couples with no IPV had the healthiest characteristics. Females in mutually violent relationships were at particularly high risk. Couple-level interventions focused on relational issues might protect young families from developing IPV behaviors. Aggr.

There has been limited study of whether and for whom physical intimate partner violence (IPV) is a consequence of an HIV-positive diagnosis. Per the diathesis stress model, the consequences of HIV infection may be worse for women with a history of IPV. We hypothesize that the positive association between HIV diagnosis in pregnancy and postpartum IPV will be exacerbated for women with a history of IPV. Data come from a prospective cohort study with 1015 participants who completed a baseline antenatal and 9-month postpartum visit. Using logistic regression analyses, we found a statistically significant interaction between HIV diagnosis, history of IPV and postpartum IPV (AOR: 0.40, 95% CI 0.17-0.96). The findings were in the opposite direction as expected: HIV-diagnosis was not associated with IPV for women with a history of IPV (AOR: 2.17, 95% CI 1.06, 4.42). However, HIV-positive women without a history of IPV faced more than two times the risk of incident postpartum IPV than HIV-negative women (AOR: 2.17, 95% CI 1.06, 4.42). Interventions to reduce incident and ongoing IPV during the perinatal period are needed.

Postpartum nurses' perceptions of barriers to screening for intimate partner violence: a cross-sectional survey

PubMed Central

2012-01-01

Background Intimate partner violence (IPV) is a human rights violation that is pervasive worldwide, and is particularly critical for women during the reproductive period. IPV includes physical, sexual and emotional abuse. Nurses on in-patient postpartum units are well-positioned to screen women for IPV, yet low screening rates suggest that barriers to screening exist. The purpose of this study was to (a) identify the frequency of screening for IPV, (b) the most important barriers to screening, (c) the relationship between the barriers to screening and the frequency of screening for types of abuse, and (d) to identify other factors that contribute to the frequency of screening for IPV. Methods In 2008, we conducted a cross-sectional survey of 96 nurses from postpartum inpatient units in three Canadian urban hospitals. The survey included the Barriers to Abuse Assessment Tool (BAAT), adapted for postpartum nurses (PPN). Ordinary least squares (OLS) regression models were used to predict barriers to screening for each type of IPV. Results The frequency of screening varied by the type of abuse with highest screening rates found for physical and emotional abuse. According to the BAAT-PPN, lack of knowledge was the most important barrier to screening. The BAAT-PPN total score was negatively correlated with screening for physical, sexual, and emotional abuse. Using OLS regression models and after controlling for demographic characteristics, the BAAT-PPN explained 14%, 12%, and 11% of the variance in screening for physical, sexual and emotional abuse, respectively. Fluency in the language of the patient was negatively correlated with screening for each type of abuse. When added as Step 3 to OLS regression models, language fluency was associated with an additional decrease in the likelihood of screening for physical (beta coefficient = -.38, P < .001), sexual (beta coefficient = -.24, P = .05), and emotional abuse (beta coefficient = -.48, P < .001) and increased the variance explained by the model to 25%, 17%, and 31%, respectively. Conclusions Our findings support an inverse relationship between rates of screening for IPV and nurses' perceptions of barriers. Barriers to screening for IPV, particularly related to knowledge and language fluency, need to be addressed to increase rates of screening on postpartum units. PMID:22348260

Informing practice regarding marginalization: the application of the Koci Marginality Index.

The 49th World Health Assembly of the World Health Organization (WHO) declared violence as the leading worldwide public health problem with a focus on the increase in the incidence of injuries to women. Violence against women is an international epidemic with specific instruments required to measure the impact on women's functioning. This article describes the application of the Koci Marginality Index (KMI), a 5-item scale to measure marginality, to the baseline data of a seven-year prospective study of 300 abused women: 150 first time users of a shelter and 150 first time applicants for a protection order from the justice system. Validity and reliability of the Koci Marginality Index and its usefulness for best clinical practice and for policy decisions for abused women's health are discussed. The 49th World Health Assembly of the World Health Organization (WHO) declared violence as the leading worldwide public health problem and focused on the increase in the incidence of injuries to women (Krug et al., 2002 ). Violence against women in the form of intimate partner violence (IPV) is costly in terms of dollars and health. In the United States in 2003, estimated costs of IPV approached $8.3 billion (Centers for Disease Control and Prevention [CDC], 2011). Outcomes related to severity of IPV vary but in 2003 victims suffering severe IPV lost nearly 8 million days of paid work, and greater than 5 million days of household productivity annually (CDC, 2011). Besides the evident financial cost of IPV, research confirms that exposure to IPV impacts a woman's health immediately and in the long-term (Breiding, Black, & Ryan, 2008 ; Campbell, 2002 ; CDC, 2011). Such sequela adversely affect the health of women and may increase their marginalization, a concept akin to isolation that may further increase negative effects on health outcomes. Immigrant women are at high risk for IPV (Erez, 2002 ) and those without documentation are at higher risk for marginalization (Montalvo-Liendo, Koci, McFarlane, Nava, Gilroy, & Maddoux, 2012). This paper explores marginality with reference to IPV and the development and application of an instrument to measure marginality.

Data from a statewide survey in India and clinic-based studies in developed settings have previously suggested an association between maternal physical intimate partner violence (IPV) experiences and the low use of antenatal care (ANC). This study aimed to explore the association between maternal experiences of physical and sexual IPV and the use of reproductive health care services, using a large nationally representative data set from Bangladesh. This paper used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 2001currently married women living with at least one child younger than 5 years. Exposure was determined from maternal reports of physical and sexual IPV. The utilization of ANC according to amount and type of provider and utilization of delivery assistance according to provider type were used as proxy outcome variables for reproductive health care utilization. Descriptive statistics and multivariate logistic regression analysis used in the study. Approximately two out of four (48.2%) respondents had experienced physical IPV. Maternal experience of physical IPV was associated with low use of receiving sufficient ANC (adjusted odds ratio [AOR] 0.69; 95% confidence interval [CI] 0.49-0.96), lower likelihood of receiving ANC (AOR 0.69; 95% CI 0.53-0.89), and assisted deliveries from skilled provider (AOR 0.54; 95% CI 0.37-0.78). Women who had been sexually abused were significantly less likely to have visited a skilled ANC and delivery care provider. Furthermore, severity of physical IPV appeared to have more profound consequences on the outcome measured. The association between exposure to IPV and use of reproductive health care services suggests that partner violence plays a significant role in lower utilization of reproductive health services among women in Bangladesh. Our findings suggest that, in addition to a wide range of socio-demographic factors, preventing maternal physical and sexual IPV need to be considered as an important psychosocial determinates for the higher utilization of reproductive health care services in Bangladesh.

Intimate partner violence (IPV) is a significant public health threat which causes injury and acute and chronic physical and mental health problems. In India, a high percentage of women experience IPV. The purposes of this study include 1) to describe the lifetime prevalence of IPV, and 2) to examine the association between IPV and physical and mental health well-being, among women utilizing community health services for the economically disadvantaged in India. Women utilizing community health services (N = 219) aged between 18 and 62 years completed a self-administered survey in Gujarat, India. Standardized instruments were used to measure perceived physical and mental health well-being. In addition, participants were asked about their lifetime experience with IPV, and socio-demographic questions. Analysis was restricted to the ever-married participants who completed the questions on IPV (N = 167). Participants with a lifetime history of IPV were more likely to have reported poorer physical and mental health compared to those without a lifetime history of IPV. More than half of the participants with an IPV history experienced multiple types of IPV (physical, sexual and/or emotional IPV). While being in the highest caste was a significant positive factor associated with better health, caste and other socio-demographic factors were not associated with IPV. Women in India face risk of IPV. Yet those experiencing IPV do not seek help or rely on informal help sources. Community health organizations may take a role in IPV prevention and intervention. Diversity of intervention options would be important to encourage more women with IPV experience to seek help.

Research addressing the impact of neighborhood factors on intimate partner violence (IPV) often lacks discussion of how and why such factors impact IPV. In order to address this gap, 16 prominent neighborhood individuals (PNI) from 4 low-income urban neighborhoods were asked to share through in-depth interviews their insights and perceptions of IPV as an issue in their neighborhoods, and the relationship between social and structural neighborhood-level factors and IPV. PNIs most often associated IPV with only physical violence. Several did not feel IPV was a significant issue in their neighborhood, confirming a lack of awareness and underreporting of IPV. However, other PNIs were able to speak of the relationship between IPV and neighborhood factors, including lack of opportunities for employment, vacant housing, trash management, lack of community awareness, and social capacity to act to address IPV. Results provide unique insights regarding the mechanisms linking neighborhood factors to IPV outcomes. These results contribute to a deeper understanding of contextual influences upon IPV, the development of tailored quantitative research and to the design of local multi-level public health IPV intervention and prevention efforts.

Gendered Social Learning, Nonfamily Institutions, and Attitudes About Recourse After Partner Violence

Objective To provide the first study in Vietnam of how gendered social learning about violence and exposure to non-family institutions influence women’s attitudes about a wife’s recourse after physical IPV. Method A probability sample of 532 married women, ages 18–50 years, was surveyed in July–August, 2012 in Mỹ Hào district. We fit a multivariate linear regression model to estimate correlates of favoring recourse in six situations using a validated attitudinal scale. We split attitudes towards recourse into three subscales (disfavor silence, favor informal recourse, favor formal recourse) and fit one multivariate ordinal logistic regression model for each behavior to estimate correlates of favoring recourse. Results On average, women favored recourse in 2.8 situations. Women who were older and had witnessed physical IPV in childhood had less favorable attitudes about recourse. Women who were hit as children, had completed more schooling, worked outside agriculture, and had sought recourse after IPV had more favorable attitudes about recourse. Conclusions Normative change among women may require efforts to curb family violence, counsel those exposed to violence in childhood, and enhance women’s opportunities for higher schooling and non-agricultural wage work. The state and organizations working on IPV might overcome pockets of unfavorable public opinion by enforcing accountability for IPV rather than seeking to alter ideas about recourse among women.

Physicians play a significant role in screening for domestic violence. However, little information is available about the prevalence of physicians who experience intimate partner violence (IPV) or the implications for their clinical practice. National surveys indicate a potential prevalence of 16% for sexual abuse and 32% for abuse by an intimate partner. This extrapolates to more than 395,000 potential physician victims, the majority of which are women. We conducted a systematic review of IPV and physician victims from 1990 to 2014 that included peer-reviewed journals, trade books, and dissertations that referenced physician victims. We identified 17 publications; nine quantitative studies, four first-person accounts, one qualitative study, and a qualitative dissertation that included two physician subjects. Two case studies of victimized physicians were identified in trade books. Quantitative results noted that women reported higher prevalence for all experiences of violence [childhood exposure (6%-32%), adult IPV exposure (7%-24%)] than men (6%-10%). This review highlights the need for improved understanding of physician experience with IPV, and development of physician-sensitive resources and treatment approaches. Contributions and limitations are provided for each publication. IPV exposure impacts clinical practice, including reticence to consistently screen patients. Lower reported prevalence may be related to extreme stigma among physicians that may prevent their reporting and help seeking, but more research is needed. We provide recommendations for clinical practice, education, and future research.

Violence related injury is a serious public health issue all over the world. This study aims to assess the association between several socio-economic factors and intimate partner violence (IPV) in Nepal. A cross-sectional study was conducted among 236 women working in carpet and garment factories in Kathmandu, Nepal. Interviews were conducted to collect quantitative data on three forms of IPV, namely physical violence, psychological violence and sexual violence, as well as on a number of potentially associated factors. Twenty-two percent of women experienced sexual IPV, 28% physical IPV and 35% psychological IPV at least once in the last 12 months. The variables independently associated with at least one form of IPV were: age of the woman >29 years [OR = 4.23, p = 0.025 for physical IPV; OR = 6.94, p = 0.008 for sexual IPV; OR = 3.42, p = 0.043 for psychological IPV], alcohol consumption of the husband [OR = 9.97, p < 0.001 for physical IPV; OR = 3.76, p = 0.004 for sexual IPV; OR = 4.85, p < 0.001 for psychological IPV], education of the husband above primary level [OR = 0.43, p = 0.013 for physical IPV; OR = 0.51, p = 0.033 for psychological IPV], and economic dependency of the woman on the husband [OR = 3.04, p = 0.021 for physical IPV; OR = 2.97, p = 0.008 for psychological IPV]. This study identified various factors associated with IPV and showed that economic dependence of wives on their husband was among the most important ones. Thus, for the prevention of IPV against women, long term strategies aiming at livelihood and economic empowerment as well as independence of women would be suggested.

We explored the relation between empathy, callous-unemotional (CU) traits, and animal abuse in a sample of 290 seven- to twelve-year-old children whose mothers were exposed to intimate partner violence (IPV). The sample comprises mostly Latino and White participants, and 55% of the children's mothers were born outside the United States (primarily Mexico). To our knowledge, among studies examining child-perpetrated animal abuse, this study is the first to examine empathy levels and one of only a few to examine CU traits. When comparing Griffith Empathy Measure (empathy) and Inventory of Callous-Unemotional Traits (callous-unemotional [CU] traits) scores with those from studies of White schoolchildren, our sample scored lower on affective empathy, higher on cognitive empathy, and lower for overall CU scores as well as Callous and Unemotional subscales. Of 290 children, 47 (16.2%) harmed an animal at least once according to either mother or child report. There were no significant sex or age differences between Abuse and No Abuse groups. The Abuse group scored significantly higher on affective empathy, CU, and Callousness/Unemotional subscales, and significantly lower on cognitive empathy. However, in regression analyses that controlled for income, only lower cognitive empathy and higher CU significantly predicted having abused an animal. In summary, low cognitive empathy (but not affective empathy) and CU traits may serve as reliable predictors of child animal abuse. However, replication of these results is necessary. A larger sample with a high percentage of Latino children whose mothers were exposed to IPV, along with a non-exposed comparison group, would be ideal.

The Role of PTSD in Bi-directional Intimate Partner Violence in Military and Veteran Populations: A Research Review.

PubMed

Misca, Gabriela; Forgey, Mary Ann

2017-01-01

Evidence supporting the higher prevalence of PTSD linked to combat-related trauma in military personnel and veteran populations is well-established. Consequently, much research has explored the effects that combat related trauma and the subsequent PTSD may have on different aspects of relationship functioning and adjustment. In particular, PTSD in military and veterans has been linked with perpetrating intimate partner violence (IPV). New research and theoretical perspectives suggest that in order to respond effectively to IPV, a more accurate understanding of the direction of the violence experienced within each relationship is critical. In both civilian and military populations, research that has examined the direction of IPV's, bi-directional violence have been found to be highly prevalent. Evidence is also emerging as to how these bi-directional violence differ in relation to severity, motivation, physical and psychological consequences and risk factors. Of particular importance within military IPV research is the need to deepen understanding about the role of PTSD in bi-directional IPV not only as a risk factor for perpetration but also as a vulnerability risk factor for victimization, as findings from recent research suggest. This paper provides a timely, critical review of emergent literature to disentangle what is known about bi-directional IPV patterns in military and veteran populations and the roles that military or veterans' PTSD may play within these patterns. Although, this review aimed to identify global research on the topic, the majority of research meeting the inclusion criteria was from US, with only one study identified from outside, from Canada. Strengths and limitations in the extant research are identified. Directions for future research are proposed with a particular focus on the kinds of instruments and designs needed to better capture the complex interplay of PTSD and bi-directional IPV in military populations and further the development of effective interventions.

One of the most common forms of violence against women is the intimate partner violence (IPV). This term includes physical, sexual, and emotional abuse and controlling behaviors by an intimate partner. This exploratory study investigates the relationship between alexithymia, adult attachment styles, depression, and coping strategies in a group of female victims of IPV and a control group. Participants were 80 female victims of IPV with an age range from 18 years to 54 years (mean 31.62; standard deviation 9.81). The control group included 80 women with no history of IPV with an age range from 19 years to 37 years (mean 25.05; standard deviation 3.67). We administered the following self-report questionnaires: (i) 20-Item Toronto Alexithymia Scale (TAS-20); (ii) Coping Orientation Problems Experienced; (iii) Beck Depression Inventory (BDI)-II; and (iv) Attachment Style Questionnaire (ASQ). Compared with control group, the IPV group showed higher mean scores on TAS-20 (52.9 vs. 41.1, P < 0.001) and BDI-II (19.50 vs. 9.95, P < 0.001). In both groups, we found significant correlations between BDI-II and TAS-20 total scores (P < 0.001) and between BDI-II and the following dimensions of ASQ: confidence (P < 0.001), discomfort with closeness (P = 0.002), relationships as secondary (P < 0.001), need for approval (P < 0.001), and preoccupation with relationships (P < 0.001). Differently from the control group, in the IPV group, social support correlated significantly and positively (P < 0.001) with the dimension preoccupation with relationships on ASQ, but not with the secure attachment style. In comparison to the control group, alexithymia, depressive symptoms, and an insecure attachment style were negatively correlated with the ability to cope with stress for women in the IPV group. © 2014 International Society for Sexual Medicine.

To analyse the Spanish primary care professionals' readiness to respond to intimate partner violence (IPV) in primary care and identify possible determinants that could facilitate a better response. A cross-sectional study with a non-probabilistic sampling by convenience was performed among healthcare professionals working in 15 primary care centres in Spain. The Physician Readiness to Manage Intimate Partner Violence Survey (PREMIS), the version validated and translated into Spanish, was the instrument used to collect information about knowledge, opinions and practices regarding intimate partner violence. Descriptive analysis and, simple and multiple linear regression analysis were performed. A total of 265 completed questionnaires were received, with a response rate of 80.3%. An exposure-response effect was observed, where at higher hours of training a higher score was obtained on the questionnaire sections (p <0.05). Age, type of profession, years of experience in primary care, hours of IPV training and reading the protocol showed positive association with knowledge (perceived preparation, perceived knowledge, actual knowledge), opinions (staff preparation, legal requirements, self-efficacy, workplace issues, constraints, understanding of the victim) and practice of healthcare professionals. Reading the regional/national protocol for action and receiving training in IPV were the most important interventions associated to a better primary care professionals' readiness to respond to IPV in Spanish primary care settings.

This study investigates the association between acceptance of intimate partner violence (IPV) and reported IPV victimization among Kenyan women, taking into consideration select sociocultural factors that may also influence acceptance of IPV. Data from a nationally representative, cross-sectional, household survey conducted between November 2008 and February 2009 in Kenya were analyzed. Hierarchical multiple regression was conducted to estimate the effect of select sociodemographic characteristics and reported IPV victimization on acceptance of IPV. The results showed that while both sociodemographic characteristics and reported IPV victimization were significantly associated with IPV acceptance, sociocultural factors had a greater impact. Programs aimed at empowering women and culturally competent IPV prevention strategies may be the key elements to reducing IPV. © The Author(s) 2014.

To determine whether adults who witnessed intimate partner violence (IPV) as children would have an increased rate of being victims of ongoing IPV, as measured by the Ongoing Violence Assessment Tool (OVAT), compared with adult controls who did not witness IPV as children. The authors also sought to determine whether there were differences in demographics in these two groups. This was a cross sectional cohort study of patients presenting to a high-volume academic emergency department. Emergency department patients presenting from November 16, 2005, to January 5, 2006, during 46 randomized four-hour shifts were included. A confidential computer touch-screen data entry program was used for collecting demographic data, including witnessing IPV as a child and the OVAT. Main outcome measures were witnessing IPV as a child, ongoing IPV, and associated demographics. Assuming a prevalence of IPV of 20% and a clinically significant difference of 20% between adults who witnessed IPV as children and adult controls who did not witness IPV as children, the study was powered at 80%, with 215 subjects included. A total of 280 subjects were entered; 256 had complete data sets. Forty-nine percent of subjects were male, 45% were Hispanic, 72 (28%) were adults who witnessed IPV as children, and 184 (72%) were adult controls who did not witness IPV as children. Sixty-three (23.5%) were positive for ongoing IPV. There was no correlation of adults who witnessed IPV as children with the presence of ongoing IPV, as determined by univariate and bivariate analysis. Twenty-three of 72 (32%) of the adults who witnessed IPV as children, and 39 of 184 (21%) of the adult controls who did not witness IPV as children, were positive for IPV (difference, 11%; 95% confidence interval [CI] = -2% to 23%). Significant correlations with having witnessed IPV as a child included age younger than 40 years (odds ratio [OR], 4.2; 95% CI = 1.7 to 9.1), income less than $20,000/year (OR, 5.1; 95% CI = 1.6 to 12.5), and abuse as a child (OR, 9.1; 95% CI = 4.2 to 19.6). Other demographics were not significantly correlated with having witnessed IPV as a child. Adults who witnessed IPV as children were more likely to have a lower income, be younger, and have been abused as a child, but not more likely to be positive for ongoing IPV, when compared with patients who had not witnessed IPV.

Intimate partner violence (IPV) is a common form of violence experienced by pregnant women and is believed to have adverse mental health effects postnatally. This study investigated the association of postnatal depression (PND) and suicidal ideation with emotional, physical and sexual IPV experienced by women during pregnancy. Data were collected from 842 women interviewed postnatally in six postnatal clinics in Harare, Zimbabwe. We used the World Health Organization versions of IPV and Centre for Epidemiological Studies - Depression Scale measures to assess IPV and PND respectively. We derived a violence severity variable and combined forms of IPV variables from IPV questions. Logistic regression was used to analyse data whilst controlling for past mental health and IPV experiences. One in five women [21.4% (95% CI 18.6-24.2)] met the diagnostic criteria for PND symptomatology whilst 21.6% (95% CI 18.8-24.4) reported postpartum suicide thoughts and 4% (95% CI 2.7-5.4) reported suicide attempts. Two thirds (65.4%) reported any form of IPV. Although individual forms of severe IPV were associated with PND, stronger associations were found between PND and severe emotional IPV or severe combined forms of IPV. Suicidal ideation was associated with emotional IPV. Other forms of IPV, except when combined with emotional IPV, were not individually associated with suicidal ideation. Emotional IPV during pregnancy negatively affects women's mental health in the postnatal period. Clinicians and researchers should include it in their conceptualisation of violence and health. Further research must look at possible indirect relationships between sexual and physical IPV on mental health. Copyright © 2016 Elsevier Inc. All rights reserved.

As Intimate Partner Violence (IPV) affects the workplace, a supportive workplace climate is important. The study evaluated the effectiveness of an "IPV and the Workplace" training on workplace climate towards IPV. IPV training was provided to 14 intervention counties and 13 control counties (receiving training 6 months delayed). Measures included workplace climate surveys, IPV knowledge test, and workplace observations. (i) Training significantly improved supervisor knowledge on IPV and received positive evaluations, (ii) training improved workplace climate towards IPV significantly which was maintained over time, and (iii) after the training, supervisors provided more IPV information to employees and more IPV postings were available in the workplace. The study provides evidence to support on-site interactive, computer based training as a means for improved workplace safety. IPV and the Workplace training effectively increased knowledge and positively changed workplace climate. Am. J. Ind.

To describe the incidence and risk factors of psychological intimate partner violence (IPV) during pregnancy and the first year after childbirth. Longitudinal cohort study. Nine primary care centers in the Valencia Region (Spain). A consecutive sample of 1400 women in the first trimester of pregnancy, attending the prenatal programme in the Valencia Region of Spain in 2008, with follow-up in the third trimester of pregnancy, and at 5 and 12 months postpartum. A total of 888 women (66.5%) participated in all four phases. A logistic regression model was fitted using generalised estimating equations to assess the effects of previous partner violence, consumption of alcohol or illicit drugs and social support on subsequent psychological partner violence. Psychological IPV during follow-up. We observed an increase in the incidence of psychological IPV after birth, particularly at 5 months postpartum. The strongest predictor of psychological IPV was having experienced abuse 12 months before pregnancy (OR 10.46, 95%CI 2.40-45.61). Other predictors were consumption of alcohol or illicit drugs by the partner or a family member (OR3.50, 95%CI 1.38-8.85) and lack of affective social support (OR2.83, 95%CI 1.31-6.11). Previous abuse and psychosocial risk factors predict partner psychological abuse after birth. Monitoring psychological IPV and effective interventions are needed not only during pregnancy but also during the postpartum period. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Visser, Margreet; Schoemaker, Kim; de Schipper, Clasien; Lamers-Winkelman, Francien; Finkenauer, Catrin

This cross-sectional study examined the hypothesis that parental psychopathology in Interparental Violence (IPV) families crosses over to children, because parental psychopathology spills over to parental functioning. In a high-risk sample of IPV exposed families, we tested whether parental psychopathology spills over to parental availability, which, in turn, shows a crossover effect to children's trauma-related symptoms. The study population consisted of 78 IPV exposed children (4-12 years), and their 65 custodial parents referred to outpatient Children's Trauma Centers in the Netherlands for intervention. Consistent with our hypotheses, parental psychopathology was negatively related to parental availability, suggesting a spillover effect. Although parental psychopathology was not associated with children's trauma-related symptoms directly, we found evidence for the predicted indirect, crossover effects. We found an indirect crossover effect from parental psychopathology to children's trauma-related anxiety, depression, and anger, through the spillover effect of parental availability. Clinical implications for treatment and study limitations are discussed.

Intimate partner violence (IPV) is associated with numerous long-term consequences and warrants significant clinical attention. Recent theoretical models and empirical research have suggested that several factors play a role in the development of IPV perpetration, including childhood maltreatment, early maladaptive schemas, anger, and difficulties in emotion regulation. This study investigated the relationship between childhood maltreatment and IPV, specifically examining the mediation of this relationship by several variables thought to be related to this pernicious problem, including early maladaptive schemas, the experience of anger, and emotion regulation difficulties. In a young adult collegiate sample of 110 women in relationships, results of a bootstrapped multiple mediation analysis supported the hypothesis that childhood maltreatment predicted physical aggression within intimate partner relationships and found that the total indirect effect of childhood maltreatment on physical aggression through the 3 proposed mediators was significant. However, consistent with recent empirical findings, only difficulties in emotion regulation significantly mediated the relationship between childhood maltreatment and physical aggression within the sample.

To avoid the risk of vaccine-associated paralytic poliomyelitis (VAPP) and polio outbreaks due to circulating vaccine-derived polioviruses, an inactivated poliovirus vaccine (IPV) was introduced for routine immunization in a number of countries with a low risk of polio outbreaks. Currently, production and marketing of a standalone conventional IPV and two diphtheria-pertussis-tetanus-IPV (Sabin-derived IPV; sIPV) products have been submitted, and it is expected that the IPV products will be introduced in Japan in the autumn of 2012. At the same time, a decline in the OPV immunization rate became apparent in Japan due to serious public concerns about a remaining risk of VAPP and introduction of IPV in the near future. Therefore, the recent development of polio immunity gaps should be carefully monitored, and surveillance of suspected polio cases and laboratory diagnosis of polioviruses have to be intensified for the transition period from OPV to IPV in Japan. The development of sIPV is one of the most realistic options to introduce affordable IPV to developing countries. In this regard, further clinical studies on its efficacy, safety, and interchangeability of sIPV will be needed after the introduction of the sIPV products, which will be licensed in Japan for the first time in the world.

Intimate partner violence (IPV) against women occurs in all countries, with wide-ranging negative effects, including on mental health. IPV rates vary widely across countries, however, suggesting cultural factors may play a role in IPV. The primary purpose of the present study was to assess relations among IPV, mental health symptoms, and cultural beliefs among Vietnamese women, focusing on moderator effects of cultural beliefs on relations between IPV and mental health. IPV, anxious and depressive mental health symptoms, and culturally-related beliefs about IPV were cross-sectionally assessed in 105 married adult Vietnamese women randomly selected from public population registries in five provinces. IPV was significantly correlated with anxiety, depression, and suicidal ideation. Relations were moderated by wives’ culturally-related beliefs about abuse (e.g., relations between IPV and mental health symptoms were smaller for women who believed that nothing could be done about abuse). Findings suggest that when attempting to prevent or treat effects of IPV, it will be important to consider that certain beliefs about IPV generally viewed as maladaptive (e.g., nothing can be done about abuse) may have adaptive effects, at least in the short-term, on relations between IPV and mental health functioning.

IPv4 network addresses are running out and the deployment of IPv6 networking in many places is now well underway. Following the work of the HEPiX IPv6 Working Group, a growing number of sites in the Worldwide Large Hadron Collider Computing Grid (WLCG) are deploying dual-stack IPv6/IPv4 services. The aim of this is to support the use of IPv6-only clients, i.e. worker nodes, virtual machines or containers. The IPv6 networking protocols while they do contain features aimed at improving security also bring new challenges for operational IT security. The lack of maturity of IPv6 implementations together with the increased complexity of some of the protocol standards raise many new issues for operational security teams. The HEPiX IPv6 Working Group is producing guidance on best practices in this area. This paper considers some of the security concerns for WLCG in an IPv6 world and presents the HEPiX IPv6 working group guidance for the system administrators who manage IT services on the WLCG distributed infrastructure, for their related site security and networking teams and for developers and software engineers working on WLCG applications.

The comparative effectiveness of Integrated treatment for Substance abuse and Partner violence (I-StoP) and substance abuse treatment alone: a randomized controlled trial

PubMed Central

2013-01-01

Background Research has shown that treatments that solely addressed intimate partner violence (IPV) perpetration were not very effective in reducing IPV, possibly due to neglecting individual differences between IPV perpetrators. A large proportion of IPV perpetrators is diagnosed with co-occurring substance use disorders and it has been demonstrated that successful treatment of alcohol dependence among alcohol dependent IPV perpetrators also led to less IPV. The current study investigated the relative effectiveness of Integrated treatment for Substance abuse and Partner violence (I-StoP) to cognitive behavioral treatment addressing substance use disorders including only one session addressing partner violence (CBT-SUD+) among patients in substance abuse treatment who repeatedly committed IPV. Substance use and IPV perpetration were primary outcome measures. Method Patients who entered substance abuse treatment were screened for IPV. Patients who disclosed at least 7 acts of physical IPV in the past year (N = 52) were randomly assigned to either I-StoP or CBT-SUD+. Patients in both conditions received 16 treatment sessions. Substance use and IPV perpetration were assessed at pretreatment, halfway treatment and posttreatment in blocks of 8 weeks. Both completers and intention-to-treat (ITT) analyses were performed. Results Patients (completers and ITT) in both conditions significantly improved regarding substance use and IPV perpetration at posttreatment compared with pretreatment. There were no differences in outcome between conditions. Completers in both conditions almost fully abstained from IPV in 8 weeks before the end of treatment. Conclusions Both I-StoP and CBT-SUD+ were effective in reducing substance use and IPV perpetration among patients in substance abuse treatment who repeatedly committed IPV and self-disclosed IPV perpetration. Since it is more cost and time-effective to implement CBT-SUD+ than I-StoP, it is suggested to treat IPV perpetrators in substance abuse treatment with CBT-SUD+.

Exclusive breastfeeding is a proven benefit for both mothers and infants and is, therefore, an important public health priority. Intimate partner violence (IPV) is regarded as one of the potential psychosocial risk factors that may negatively affect exclusive breastfeeding (EBF). This study aimed to explore the influence of psychosocial factors including IPV on EBF. Cross-sectional survey data was collected from October 2015 to January 2016 in Chandpur District of Bangladesh from 426 married women, aged 15-49 years, who had at least one child 6 months of age or younger. Multivariate logistic regression models were used in order to investigate whether women who experienced IPV after childbirth, as well as other risk factors such as postpartum depression (PPD) and childhood sexual abuse, were more likely to face difficulties with EBF compared with women who had not experienced these same risk factors. Whilst the initiation rate of breastfeeding was 99.3%, at the time of the woman's interview, the overall EBF rate had fallen to 43.7%. Based on the adjusted model, women who experienced physical IPV (AOR 0.17, 95% CI [0.07, 0.40]) and psychological IPV (AOR 0.51, 95% CI [0.26, 1.00]) after childbirth and women who reported childhood sexual abuse (AOR 0.32, 95% CI [0.13, 0.80]) and PPD (AOR 0.20, 95% CI [0.09, 0.44]) were significantly less likely to exclusively breastfeed their infants than those who had not reported these experiences. Moreover, women with an intended pregnancy and high social support exhibited a higher likelihood of EBF. Our results suggest that preventing or reducing the occurrence of physical IPV, PPD and childhood sexual abuse may improve the EBF duration. Support from family members can assist in this process.

Subtyping male perpetrators of intimate partner violence (IPV) based on their generality of violence could facilitate the difficult task of matching perpetrator subtype with efficient risk management strategies. As such, the aim of the present study was to compare antisocial and family-only male perpetrators of interpersonal violence in terms of (a) demographic and legal characteristics, (b) risk factors for violence, and (c) assessed risk and the importance of specific risk factors for violence. A quantitative design was used in this retrospective register study on data obtained from the Swedish police. Risk assessments performed with the Swedish version of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) and police registers were used. A sample of 657 male alleged IPV perpetrators were classified asantisocial(n= 341) orfamily-only(n= 316) based on their generality of violence. The results showed that the antisocial perpetrators were significantly younger, as well as more psychologically abusive. Antisocial perpetrators also had significantly more present risk factors for IPV, and were assessed with a significantly higher risk for acute and severe or deadly IPV, compared with the family-only perpetrators. The subtypes also evidenced unique risk factors with a significant impact on elevated risk for acute and severe or deadly such violence. Key findings in the present study concerned the subtypes evidencing unique risk factors increasing the risk for acute and severe or deadly IPV. Major implications of this study include the findings of such unique "red flag" risk factors for each subtype. To prevent future IPV, it is vital for the risk assessor to be aware of these red flags when making decisions about risk, as well as risk management strategies. © The Author(s) 2016.

Traumatic events can negatively affect clinical outcomes among HIV positive women, particularly when those events result in ongoing psychological distress. Consequently, there have been calls to integrate screening and treatment of traumatic experiences and associated mental health disorders into HIV care. In South Africa, screening for traumatic experiences and mental health is not a routine part of HIV care. The goal of this study was to examine the prevalence of traumatic experiences and mental health distress among women in an HIV clinic in Cape Town, South Africa, and to explore the acceptability of routine screening in this setting. Seventy HIV positive women were screened following referral from health care workers in the clinic. Among the participants, 51% reported a history of sexual abuse and 75% reported physical intimate partner violence (physical IPV). Among all participants, 36% met screening criteria for depression; among those with traumatic experiences ( n = 57), 70% met screening criteria for posttraumatic stress disorder (PTSD). Compared with reporting no sexual abuse or physical IPV, having experienced both sexual abuse and physical IPV was significantly associated with higher odds of depression, while reporting either sexual abuse or physical IPV individually was not significantly associated with increased odds of depression. Among women reporting sexual abuse, 61% were disclosing their experience for the first time during the screening; 31% of women with physical IPV experience were disclosing for the first time. Overall, 98% of participants thought screening should be routine and extended to all women as part of clinic care. Screening women for sexual abuse and physical IPV may be an important component of ensuring HIV care engagement.

Intimate Partner Violence and Women's Mental Health: The Mediating Role of Coping Strategies Among Women Seeking Help From the Police.

Many variables explain the link between intimate partner violence (IPV) and its impact on women's mental health. This proposition is mostly from samples drawn from battered women's shelters, batterer intervention programs (BIPs), emergency rooms, and medical clinics. We know little about the psychological well-being of women who report abuse to police departments. This study used data from case records of women who experience IPV and sought help from a city police station located in the southwest United States. These case records were examined to identify how sociodemographic characteristics of age, ethnicity, marital status, financial dependence, resources of social support, and coping strategies related with type and number of IPV incidents as well as mental health symptoms. The sample consisted of 154 women, majority of whom experienced physical violence (70.1%), sexual violence (9.1%), emotional violence/stalking (14.9%), and combined, that is, reporting more than one (5.8%). Approximately 67.5% of the women reported some mental health symptoms. Social support and coping strategies significantly distinguished women's experience of mental health symptoms. Unexpectedly, the current data indicate that women who scored higher in perceived social support significantly reported more mental health symptoms. Coping strategies mediated the relationship between IPV and mental health symptoms. The findings suggest that availability of coping resources may mitigate repeated IPV and modify the impact of mental health. In discussing prevention and intervention efforts with women who have experienced or are at risk of experiencing IPV, practitioners can help women employ empowering coping strategies that are built on their resilience. In addition, mental health professionals working with the police, especially in community policing setting, can achieve promising outcomes for women experiencing violence.

Intimate partner violence (IPV) is a global public health problem. Orthopedic surgery residents may identify IPV among injured patients treated in fracture clinics. Yet, these residents face a number of barriers to recognizing and discussing IPV with patients. We sought to explore orthopedic surgery residents' knowledge of IPV and their preparedness to screen patients for IPV in academic fracture clinic settings with a view to developing targeted IPV education and training. We conducted focus groups with junior and intermediate residents. Discussions explored residents' knowledge of and experiences with IPV screening and preparedness for screening and responding to IPV among orthopedic patients. Data were analyzed iteratively using an inductive approach. Residents were aware of the issue of abuse generally, but had received no specific information or training on IPV in orthopedics. Residents did not see orthopedics faculty screen patients for IPV or advocate for screening. They did not view IPV screening or intervention as part of the orthopedic surgeon's role. Residents' clinical experiences emphasized time management and surgical intervention by effectively "getting through clinic" and "dealing with the surgical problem." Communication with patients about other health issues was minimal or nonexistent. Orthopedic surgery residents are entering a career path where IPV is well documented. They encounter cultural and structural barriers preventing the incorporation of IPV screening into their clinical and educational experiences. Hospitals and academic programs must collaborate in efforts to build capacity for sustainable IPV screening programs among these trainees.

The study assessed the relationship between postpartum intimate partner violence (IPV) and postpartum health risks among young mothers over time. Data were collected from 2001 to 2005 on young women aged 14–25 attending obstetrics and gynecology clinics in two US cities. Postpartum IPV (i.e., emotional, physical, sexual) was assessed at 6 and 12 months after childbirth (n = 734). Four types of postpartum IPV patterns were examined: emerged IPV, dissipated IPV, repeated IPV, and no IPV. Emerged IPV occurred at 12 months postpartum, not 6 months postpartum. Dissipated IPV occurred at 6 months postpartum, not 12 months postpartum. Repeated IPV was reported at 6 months and 12 months postpartum. Postpartum health risks studied at both time points were perceived stress, depression, fear of condom negotiation, condom use, infant sleeping problems, and parental stress. Repeated measures analysis of covariance was used. The proportion of young mothers reporting IPV after childbirth increased from 17.9 % at 6 months postpartum to 25.3 % at 12 months postpartum (P < 0.001). Emerged and/or repeated postpartum IPV were associated with increased perceived stress, depression, fear of condom negotiation, and infant sleeping problems as well as decreased condom use (P < 0.05). Dissipated postpartum IPV was associated with decreased depression (P < 0.05). IPV screening and prevention programs for young mothers may reduce health risks observed in this group during the postpartum period. PMID:24562504

Some gynaecological and pregnancy-associated conditions are more common in abused women than in non-abused women, but this has not been examined in family practice. We aimed to investigate intimate partner violence (IPV) prevalence in family practice and to investigate whether gynaecological and pregnancy-associated conditions are more common in abused women than in non-abused women. We conducted a cross-sectional waiting room survey in 12 family practices in the Netherlands in 2012. Women were eligible if they were of 18 years or older. Questionnaires measured IPV and gynaecological and pregnancy-associated conditions. Chi-square tests were used to assess the differences in gynaecological and pregnancy-associated conditions between abused women and non-abused women. The response rate was 86% (262 of 306 women). The past-year prevalence of IPV in women who had had an intimate relationship in the past year and were not accompanied by their partner was 8.7% (n = 195). Lifetime prevalence of women who had ever had an intimate relationship, but not in the past year, was 17.6% (n = 51). Sexually transmitted infections (STIs) [odds ratio (OR) = 4.6, 95% confidence interval [CI] = 1.7-12.5, n = 240], menstrual disorders (OR = 3.7, 95% CI = 1.2-11.2, n = 143), sexual problems (OR = 3.3, 95% CI = 1.2-9.3, n = 229), miscarriages (OR = 2.5, 95% CI = 1.062-5.8, n = 202) and induced abortions (OR = 2.7, 95% CI = 1.028-7.3, n = 202) were significantly more common in abused women than in non-abused women. Family physicians should ask about IPV when women present with STIs, menstrual disorders, sexual problems, miscarriages or induced abortions. To improve the recognition of IPV, future research needs to investigate whether a combination of symptoms offers improved prediction of IPV. © The Author 2016. Published by Oxford University Press.

Objective We examined associations of childhood physical and sexual abuse with risk of intimate partner violence (IPV). We also evaluated the extent to which childhood abuse was associated with self-reported general health status and symptoms of antepartum depression in a cohort of pregnant Peruvian women. Methods In-person interviews were conducted to collect information regarding history of childhood abuse and IPV from 1,521 women during early pregnancy. Antepartum depressive symptomatology was evaluated using the Patient Health Questionnaire-9. Multivariable logistic regression procedures were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95%CI). Results Any childhood abuse was associated with 2.2-fold increased odds of lifetime IPV (95%CI: 1.72–2.83). Compared with women who reported no childhood abuse, those who reported both, childhood physical and sexual abuse had a 7.14-fold lifetime risk of physical and sexual IPV (95%CI: 4.15–12.26). The odds of experiencing physical and sexual abuse by an intimate partner in the past year was 3.33-fold higher among women with a history of childhood physical and sexual abuse as compared to women who were not abused as children (95%CI 1.60–6.89). Childhood abuse was associated with higher odds of self-reported poor health status during early pregnancy (aOR = 1.32, 95%CI: 1.04–1.68) and with symptoms of antepartum depression (aOR = 2.07, 95%CI: 1.58–2.71). Conclusion These data indicate that childhood sexual and physical abuse is associated with IPV, poor general health and depressive symptoms in early pregnancy. The high prevalence of childhood trauma and its enduring effects of on women’s health warrant concerted global health efforts in preventing violence. PMID:25635902

Performance analysis for wireless networks: an analytical approach by multifarious Sym Teredo.

IPv4-IPv6 transition rolls out numerous challenges to the world of Internet as the Internet is drifting from IPv4 to IPv6. IETF recommends few transition techniques which includes dual stack and translation and tunneling. By means of tunneling the IPv6 packets over IPv4 UDP, Teredo maintains IPv4/IPv6 dual stack node in isolated IPv4 networks behindhand network address translation (NAT). However, the proposed tunneling protocol works with the symmetric and asymmetric NATs. In order to make a Teredo support several symmetric NATs along with several asymmetric NATs, we propose multifarious Sym Teredo (MTS), which is an extension of Teredo with a capability of navigating through several symmetric NATs. The work preserves the Teredo architecture and also offers a backward compatibility with the original Teredo protocol.

Stephenson, Rob; Finneran, Catherine

2017-08-01

Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations, with increasing evident that gay men experience IPV at the same rates as heterosexual women. This study examines the relationship between self-reported condomless anal intercourse (CAI) and IPV among a sample of 750 gay and bisexual men. Participants answered questions regarding recent receipt and perpetration of IPV using the IPV-GBM Scale (Cronbach Alpha 0.90). Of the sample, 46.1% reported recent receipt of any type of IPV and 33.6% reported recent perpetration of any type of IPV. Overall, 55.1% of participants reported CAI at last sex. Significant associations were determined between several forms of IPV and increased odds of reporting CAI at last sex. These findings suggest that IPV may be a risk factor for CAI among men who have sex with men, and highlight the need to understand the IPV prevention and care needs of this population.

Male perpetration of intimate partner violence (IPV) is under-researched. In this Article, we present data for the prevalence of, and factors associated with, male perpetration of IPV from the UN Multi-country Cross-sectional Study on Men and Violence in Asia and the Pacific. We aimed to estimate the prevalence of perpetration of partner violence, identify factors associated with perpetration of different forms of violence, and inform prevention strategies. We undertook standardised population-based household surveys with a multistage representative sample of men aged 18-49 years in nine sites in Bangladesh, China, Cambodia, Indonesia, Sri Lanka, and Papua New Guinea between January, 2011, and December, 2012. We built multinomial regression models of factors associated with lifetime violence perpetration: physical IPV, sexual IPV, both physical and sexual IPV, multiple emotional or economic IPV versus none, and calculated population-attributable fractions. In the analysis, we considered factors related to social characteristics, gender attitudes and relationship practices, victimisation history, psychological factors, substance misuse, and participation in violence outside the home. 10,178 men completed interviews in our study (between 815 and 1812 per site). The response rate was higher than 82·5% in all sites except for urban Bangladesh (73·2%) and Sri Lanka (58·7%). The prevalence of physical or sexual IPV perpetration, or both, varied by site, between 25·4% (190/746; rural Indonesia) and 80·0% (572/714; Bougainville, Papua New Guinea). When multiple emotional or economic abuse was included, the prevalence of IPV perpetration ranged from 39·3% (409/1040; Sri Lanka) to 87·3% (623/714; Bougainville, Papua New Guinea). Factors associated with IPV perpetration varied by country and type of violence. On the basis of population-attributable fractions, we show factors related to gender and relationship practices to be most important, followed by experiences of childhood trauma, alcohol misuse and depression, low education, poverty, and involvement in gangs and fights with weapons. Perpetration of IPV by men is highly prevalent in the general population in the sites studied. Prevention of IPV is crucial, and interventions should address gender socialisation and power relations, abuse in childhood, mental health issues, and poverty. Interventions should be tailored to respond to the specific patterns of violence in various contexts. Physical and sexual partner violence might need to be addressed in different ways.

2014-01-01

Background Intimate partner violence (IPV) is a global public health problem. Orthopedic surgery residents may identify IPV among injured patients treated in fracture clinics. Yet, these residents face a number of barriers to recognizing and discussing IPV with patients. We sought to explore orthopedic surgery residents’ knowledge of IPV and their preparedness to screen patients for IPV in academic fracture clinic settings with a view to developing targeted IPV education and training. Methods We conducted focus groups with junior and intermediate residents. Discussions explored residents’ knowledge of and experiences with IPV screening and preparedness for screening and responding to IPV among orthopedic patients. Data were analyzed iteratively using an inductive approach. Results Residents were aware of the issue of abuse generally, but had received no specific information or training on IPV in orthopedics. Residents did not see orthopedics faculty screen patients for IPV or advocate for screening. They did not view IPV screening or intervention as part of the orthopedic surgeon’s role. Residents’ clinical experiences emphasized time management and surgical intervention by effectively “getting through clinic” and “dealing with the surgical problem.” Communication with patients about other health issues was minimal or nonexistent. Conclusion Orthopedic surgery residents are entering a career path where IPV is well documented. They encounter cultural and structural barriers preventing the incorporation of IPV screening into their clinical and educational experiences. Hospitals and academic programs must collaborate in efforts to build capacity for sustainable IPV screening programs among these trainees. PMID:25421078

Intimate partner violence (IPV) is a major public health problem, and recent attention has focused on its impact on workers and workplaces. We provide findings from a pan-Canadian online survey on the relationships among IPV, work, and health. In total, 8,429 people completed the survey, 95.5% of them in English and 78.4% female. Reflecting the recruitment strategy, most (95.4%) were currently working, and unionized (81.4%). People with any lifetime IPV experience reported significantly poorer general health, mental health, and quality of life; those with both recent IPV and IPV experience over 12 months ago had the poorest health. Among those who had experienced IPV, about half reported that violence occurred at or near the workplace, and these people generally had poorer health outcomes. Employment status moderated the relationship between IPV exposure and health status, with those who were currently working and had experienced IPV having similar health status to those without IPV experience who were not employed. While there were gender differences in IPV experience, in the impacts of IPV at work, and in health status, gender did not moderate any associations. In this very large data set, we found robust relationships among different kinds of IPV exposure (current, recent, and lifetime), health and quality of life, and employment status, including the potentially protective effect of current employment on health for both women and men. Our findings may have implications for strategies to address IPV in workplaces, and should reinforce emerging evidence that IPV is also an occupational health issue.

Gender inequity is a risk factor for intimate partner violence (IPV), although there is little research on this relationship that focuses on youth or males. Using survey data collected from 240 male and 198 female youth aged 15-24 in Rio de Janeiro, Brazil, we explore the association between individual-level support for gender equity and IPV experiences in the past 6 months and describe responses to and motivations for IPV. Factor analysis was used to construct gender equity scales for males and females. Logistic and multinomial logistic regression models were used to examine the relationship between gender equity and IPV. About half of female youth reported some form of recent IPV, including any victimization (32%), any perpetration (40%), and both victimization and perpetration (22%). A total of 18% of male youth reported recently perpetrating IPV. In logistic regression models, support for gender equity had a protective effect against any female IPV victimization and any male IPV perpetration and was not associated with female IPV perpetration. Female victims reported leaving the abusive partner, but later returning to him as the most frequent response to IPV. Male perpetrators said the most common response of their victims was to retaliate with violence. Jealousy was the most frequently reported motivation of females perpetrating IPV. Gender equity is an important predictor of IPV among youth. Examining the gendered context of IPV will be useful in the development of targeted interventions to promote gender equity and healthy relationships and to help reduce IPV among youth.

Research suggests that posttraumatic stress disorder (PTSD) and depression are two common mental health problems in intimate partner violence (IPV) survivors. Research has found that while Black women consistently report higher rates of victimization than White women, they also report less severe PTSD and depressive symptoms, suggesting that Black IPV survivors might be more resilient to PTSD and depression than are White survivors. We implemented a correlational study with 81 Black and 100 White female survivors of IPV to determine if John Henryism (JH; i.e., a predisposed active coping mechanism) contributes to the resilience observed in Black IPV survivors. Participants completed the John Henryism Active Coping Scale, Center for Epidemiological Studies Depression Scale, Davidson Trauma Scale, and the Abusive Behavior Inventory. Results demonstrated that White woman endorsed more severe depressive symptoms as compared to Black women. Severity of PTSD symptoms and JH was not significantly different between races. JH did not moderate the relationship between race and depression; however, for PTSD, JH was found to be protective of PTSD in White women, while demonstrating little impact on Black women. The implications of these findings are discussed in terms of the minority stress model.

Abstract Intimate partner violence (IPV) is a complex and global phenomenon that requires a multi-perspective analysis. Nevertheless, the number of neuroscientific studies conducted on this issue is scarce as compared with studies of other types of violence, and no neuroimaging studies comparing batterers to other criminals have been conducted. Thus, the main aim of this study was to compare the brain functioning of batterers to that of other criminals when they are exposed to IPV or general violence pictures. An fMRI study was conducted in 21 batterers and 20 other criminals while they observed IPV images (IPVI), general violence images (GVI) and neutral images (NI). Results demonstrated that batterers, compared with other criminals, exhibited a higher activation in the anterior and posterior cingulate cortex and in the middle prefrontal cortex and a decreased activation in the superior prefrontal cortex to IPVI compared to NI. The paired t-test comparison between IPVI and GVI for each group showed engagement of the medial prefrontal cortex, the posterior cingulate and the left angular cortices to IPVI in the batterer group only. These results could have important implications for a better understanding of the IPV phenomenon. PMID:26884544

Setting an Agenda to Address Intimate Partner Violence Among Young Men Who Have Sex With Men: A Conceptual Model and Review.

Research investigating intimate partner violence (IPV) among sexual minorities is limited. The research that does exist has found that rates of IPV are similar to or higher than the rates found for heterosexual women, the most commonly studied population in this area. This limited research has resulted in a dearth of prevention/intervention programs targeted for these populations. While some may argue that existing IPV programs can be used for these populations, this review presents an argument for more targeted work with sexual minority populations, using young men who have sex with men (YMSM) as an example. Drawing on the framework of intersectionality, this article argues that the intersectionality of age, sexual identity, and gender combines to create a spectrum of unique factors that require specific attention. This framework allows for the identification of known correlates for IPV as well as factors that may be unique to YMSM or other sexual minority populations. The article presents a conceptual model that suggests new areas of research as well as a foundation for the topics and issues that should be addressed in an intervention. © The Author(s) 2016.

Study Objectives This study assesses VA mental health providers’ understanding of intimate partner violence (IPV) and the perception of patient benefit of routine inquiry and service referral. The impact of an instructional curriculum was also examined following an interactive training. Methods An evidence-based curriculum was offered to VA mental health providers. The curriculum utilized didactic methods, case scenarios, and resources regarding referrals and statutes regarding crimes related to violence and abuse. The participants completed pre- and post-training surveys to assess their perceptions about IPV and to evaluate the training. Results Seventy-three individuals completed the training. Fifty-four of the participants were female, and thirty-three were over the age of 45. Fifty-one individuals completed both surveys. There were no differences between participants’ views of the seriousness of IPV in the community or their practices before or after the training. However, participants scored significantly higher on the knowledge and efficacy measures after the training (p<.001). Conclusion Following an educational intervention, providers demonstrate more knowledge and efficacy regarding routine inquiry and referral for IPV. Barriers to universal implementation still warrant attention. PMID:22165653

2017-04-01

Latina immigrant women are vulnerable and may experience higher levels of interpersonal or intimate partner violence (IPV) due to their immigrant status and cultural emphasis on familism. The concept of empowerment within the cultural context of Latina immigrant women experiencing IPV was analyzed using a modified version of Walker and Avant's concept analysis technique. The technique considers usage and definitions in the literature, antecedents, attributes, empirical referents, and the inclusion of a model and contrary case. This analysis encompasses a comparative approach and includes a discussion of how the definition of empowerment compares across the nursing literature. Defining attributes include reciprocal relationships, autonomy, and accountability. Antecedents comprise willingness to learn and motivation to create change. Consequences encompass self-esteem, self-efficacy, and competence for making life decisions. Empowerment has the potential to improve total well-being, having a positive and profound impact on the lives of women experiencing IPV.

Intimate partner violence (IPV) is one of the most common forms of violence against women worldwide. Among Mexican women, it is estimated that 15 to 71% have experienced physical or sexual abuse by an intimate male partner in their lifetime. This study examined the prevalence of four leading risk factors associated with IPV (alcohol consumption, education, socioeconomic status (SES), and gender roles) in adult women (n = 68) in a migrant farmworker community in México. Alcohol consumption among women was higher than the national average, and partner consumption was lower. Education level and SES were low, and women identified with a feminist ideology more than a traditional gender role. Results also revealed that 86.4% (n = 57) of participants identified violence against women as a common problem in the community, and the majority (94.0%, n = 62) of participants believe that IPV specifically is a problem within the community.

To describe intimate partner violence (IPV) services available through employee assistance programs (EAPs) and determine women's satisfaction with these services. A mixed-methods study consisting of semistructured telephone interviews with 28 EAPs about IPV-related services and a national web-based survey of 1765 women regarding their interactions with EAPs when seeking IPV-related assistance. Data were collected in the fall of 2008. EAPs provide fairly extensive services to individuals experiencing IPV. Satisfaction with EAP services for IPV was significantly associated with annual income and the type of help received from the EAP, but not with type of IPV experienced. EAP representatives described challenges with accurately identifying IPV victims and women expressed concerns with confidentiality. Future efforts to enhance the ability of EAPs to respond effectively to IPV should address confidentially and strengthen how IPV-related assistance is delivered.

The world is rapidly running out of IPv4 addresses; the number of IPv6 end systems connected to the internet is increasing; WLCG and the LHC experiments may soon have access to worker nodes and/or virtual machines (VMs) possessing only an IPv6 routable address. The HEPiX IPv6 Working Group has been investigating, testing and planning for dual-stack services on WLCG for several years. Following feedback from our working group, many of the storage technologies in use on WLCG have recently been made IPv6-capable. This paper presents the IPv6 requirements, tests and plans of the LHC experiments together with the tests performed on the group's IPv6 test-bed. This is primarily aimed at IPv6-only worker nodes or VMs accessing several different implementations of a global dual-stack federated storage service. Finally the plans for deployment of production dual-stack WLCG services are presented.

Intimate partner violence (IPV) is a significant public health problem in South Africa. However, limited research exists on IPV during pregnancy and the postpartum period in South Africa. The purpose of this study is to describe the prevalence, rates and correlates of IPV among South African women during pregnancy and the first 9 months postpartum. Data are from a longitudinal study with women recruited during pregnancy between 2008 and 2010 at a public clinic in Durban. We used a modified version of the World Health Organization's IPV scale to estimate prevalence and rates of IPV during pregnancy, at 4 months postpartum and 9 months postpartum and we used logistic regression to assess the correlates of IPV during this time. More than 20 % of all women experienced at least one act of physical, psychological or sexual IPV during pregnancy. Nearly one-quarter of all women experienced at least one act of physical, psychological or sexual IPV during the first 9 months postpartum. Psychological IPV was the most prevalent type of IPV during pregnancy and the first 4 months postpartum. Age and previous violence within the relationship were associated with IPV during pregnancy and IPV during the postpartum period. The high levels of IPV during pregnancy and the postpartum period highlight the need to develop screening and intervention strategies specifically for this time. Further, women should be screened not only for physical violence but also psychological violence given that psychological violence may result in distinct negative consequences.

Previous research suggests that health care providers' assumptions about the content and marketing of intimate partner violence (IPV) materials are not always correct and may do harm. This study sought to determine what mothers with histories of IPV identify as important information to communicate about IPV and how it should be presented in a pediatric emergency department. This qualitative study used English- and Spanish-speaking focus groups for data collection and a grounded theory approach for data analysis. Initial focus groups elicited opinions on content, appearance, and location of IPV material. After data analysis, IPV posters were developed. Follow-up focus groups provided feedback on the posters. Ninety-nine mothers with histories of IPV participated in 8 initial and 4 follow-up focus groups. Women felt information should be presented in a positive, hopeful manner. Key information desired was signs of IPV, effects of childhood IPV exposure, and available resources. Spanish-speaking groups desired that information that helps was available regardless of immigration status. Women cautioned that information regarding the effects of childhood IPV exposure should be presented in a nonjudgmental manner to minimize feelings of anger and guilt in mothers. Participants endorsed the distribution of IPV materials in many formats and locations but also worried that women might suffer retribution if perpetrators see IPV material. Passive educational interventions for IPV should present information about the signs of IPV, resources, and effects on children in a positive, hopeful manner. Materials directed toward Spanish-speaking victims should address the issue of immigration status.

There is growing awareness of the problem of intimate partner violence (IPV) among military populations. IPV victimisation has been shown to be associated with mental disorder. A better understanding of the link between IPV and mental disorder is needed to inform service development to meet the needs of military families. We aimed to systematically review the literature on the association between IPV victimisation and mental health disorders among military personnel. Searches of four electronic databases (Embase, Medline, PsycINFO, and Web of Science) were supplemented by reference list screening. Heterogeneity among studies precluded a meta-analysis. Thirteen studies were included. There was stronger evidence for an association between IPV and depression/alcohol problems than between IPV and PTSD. An association between IPV and mental health problems was more frequently found among veterans compared to active duty personnel. However, the link between IPV and alcohol misuse was more consistently found among active duty samples. Finally, among active duty personnel psychological IPV was more consistently associated with depression/alcohol problems than physical/sexual IPV. The review highlighted the lack of research on male IPV victimisation in the military. There is evidence that the burden of mental health need may be significant among military personnel who are victims of IPV. The influence of attitudes towards gender in the military on research in this area is discussed. Further research is needed to inform development of services and policy to reduce IPV victimisation and the mental health consequences among military personnel.

Intimate partner violence norms cluster within households: an observational social network study in rural Honduras.

Intimate partner violence (IPV) is a complex global problem, not only because it is a human rights issue, but also because it is associated with chronic mental and physical illnesses as well as acute health outcomes related to injuries for women and their children. Attitudes, beliefs, and norms regarding IPV are significantly associated with the likelihood of both IPV experience and perpetration. We investigated whether IPV acceptance is correlated across socially connected individuals, whether these correlations differ across types of relationships, and whether social position is associated with the likelihood of accepting IPV. We used sociocentric network data from 831 individuals in rural Honduras to assess the association of IPV acceptance between socially connected individuals across 15 different types of relationships, both within and between households. We also investigated the association between network position and IPV acceptance. We found that having a social contact that accepts IPV is strongly associated with IPV acceptance among individuals. For women the clustering of IPV acceptance was not significant in between-household relationships, but was concentrated within households. For men, however, while IPV acceptance was strongly clustered within households, men's acceptance of IPV was also correlated with people with whom they regularly converse, their mothers and their siblings, regardless of household. We also found that IPV was more likely to be accepted by less socially-central individuals, and that the correlation between a social contact's IPV acceptance was stronger on the periphery, suggesting that, as a norm, it is held on the periphery of the community. Our results show that differential targeting of individuals and relationships in order to reduce the acceptability and, subsequently, the prevalence of IPV may be most effective. Because IPV norms seem to be strongly held within households, the household is probably the most logical unit to target in order to implement change. This approach would include the possible benefit of a generational effect. Finally, in social contexts in which perpetration of IPV is not socially acceptable, the most effective strategy may be to implement change not at the center but at the periphery of the community.

An inactivated poliovirus vaccine (IPV) based on attenuated poliovirus strains (Sabin-1, -2 and -3) was developed for technology transfer to manufacturers in low- and middle-income countries in the context of the global polio eradication initiative. Safety and immunogenicity of Sabin-IPV (sIPV) was evaluated in a double-blind, randomized, controlled, dose-escalation trial in the target population. Healthy infants (n=20/group) aged 56-63 days, received a primary series of three intramuscular injections with low-, middle- or high-dose sIPV with or without aluminum hydroxide or with the conventional IPV based on wild poliovirus strains (wIPV). Virus-neutralizing titers against both Sabin and wild poliovirus strains were determined before and 28 days after three vaccinations. The incidence of local and systemic reactions was comparable with the wIPV. Seroconversion rates after three vaccinations were 100% for type 2 and type 3 polioviruses (both Sabin and wild strains) and 95-100% for type 1 polioviruses. Median titers were high in all groups. Titers were well above the log2(titer) correlated with protection (=3) for all groups. Median titers for Sabin-2 were 9.3 (range 6.8-11.5) in the low-dose sIPV group, 9.2 (range 6.8-10.2) in the low-dose adjuvanted sIPV group and 9.8 (range 5.5-15.0) in the wIPV group, Median titers against MEF-1 (wild poliovirus type 2) were 8.2 (range 4.8-10.8) in the low-dose sIPV group, 7.3 (range 4.5-10.2) in the low-dose adjuvanted Sabin-IPV group and 10.3 (range 8.5-17.0) in the wIPV group. For all poliovirus types the median titers increased with increasing dose levels. sIPV and sIPV adjuvanted with aluminum hydroxide were immunogenic and safe at all dose levels, and comparable with the wIPV.

Women's police stations and intimate partner violence: Evidence from Brazil.

PubMed

Perova, Elizaveta; Reynolds, Sarah Anne

2017-02-01

Although women's police stations have gained popularity as a measure to address intimate partner violence (IPV), there is little quantitative evaluation of their impacts on the incidence of IPV. This paper estimates the effects of women's police stations in Brazil on female homicides, a measure of the most severe form of IPV. Given that a high fraction of female deaths among women ages 15-49 years can be attributed to aggression by an intimate partner, female homicides appear the best proxy for severe IPV considering the scarcity of data on IPV in Brazil. We assemble a panel of 2074 municipalities from 2004 to 2009 and apply a difference-in-differences approach using location and timing to estimate the effect of establishing a women's police station on the municipal female homicide rate. Although we do not find a strong association on average, women's police stations appear to be highly effective among young women living in metropolitan areas. Establishing a women's police station in a metropolitan municipality is associated with a reduction in the female homicide rate by 1.23 deaths per 100,000 women ages 15-49 years (approximately a 17 percent reduction in the female homicide rate in metropolitan municipalities). The reduction in the homicide rate of women ages 15 to 24 is even higher: 5.57 deaths per 100,000 women. Better economic opportunities and less traditional social norms in metropolitan areas may explain the heterogeneous impacts of women's police stations. Copyright © 2016. Published by Elsevier Ltd.

Young men who have sex with men (YMSM) continue to experience higher rates of HIV infection than other populations. Recently, there have been recommendations to consider HIV prevention at the dyadic or couple level. Using a dyadic approach to HIV prevention would also address an unaddressed concern related to intimate partner violence (IPV) among YMSM. Although research on IPV among YMSM is still in its infancy, great strides have been made in the past 10 years to describe the prevalence and related correlates of IPV within older adult same-sex relationships. These studies have found rates of IPV among MSM to be similar to rates among heterosexual women, and to be on the rise. The present study is designed to provide insight into how power is conceptualized within YMSM relationships and the role it may play in relationship challenges. This study draws from qualitative data collected from 11 focus groups with 86 YMSM and 26 individual semi-structured interviews to understand relationship challenges and the experiences of YMSM involved in partner violence. YMSM described relationship power as stemming from numerous sources including sexual positioning, gender roles, education, income, prior relationship experiences, and internalized homophobia. The findings have a number of implications for service providers and program design. Interventionists and other researchers need to consider power dynamics and other contextual elements of IPV before effective interventions can be developed for YMSM and other sexual minority populations. © The Author(s) 2014.

IPv6 testing and deployment at Prague Tier 2

Computing Center of the Institute of Physics in Prague provides computing and storage resources for various HEP experiments (D0, Atlas, Alice, Auger) and currently operates more than 300 worker nodes with more than 2500 cores and provides more than 2PB of disk space. Our site is limited to one C-sized block of IPv4 addresses, and hence we had to move most of our worker nodes behind the NAT. However this solution demands more difficult routing setup. We see the IPv6 deployment as a solution that provides less routing, more switching and therefore promises higher network throughput. The administrators of the Computing Center strive to configure and install all provided services automatically. For installation tasks we use PXE and kickstart, for network configuration we use DHCP and for software configuration we use CFEngine. Many hardware boxes are configured via specific web pages or telnet/ssh protocol provided by the box itself. All our services are monitored with several tools e.g. Nagios, Munin, Ganglia. We rely heavily on the SNMP protocol for hardware health monitoring. All these installation, configuration and monitoring tools must be tested before we can switch completely to IPv6 network stack. In this contribution we present the tests we have made, limitations we have faced and configuration decisions that we have made during IPv6 testing. We also present testbed built on virtual machines that was used for all the testing and evaluation.

Women with schizophrenia are a vulnerable risk group for intimate partner violence (1PV). There are few surveys that highlight the pattern, prevalence and association of IPV with psychopathology in these vulnerable group of women in South-South Nigeria. The aim of the study was to survey the forms, prevalence and association of Intimate partner violence with psychopathology. The study was a cross-sectional survey of 77 female patients diagnosed with schizophrenia who were outpatients at the Federal Neuro-psychiatric Hospital, Calabar, Cross-River State in South-South region of Nigeria. A total of 58 out of 77 (75 %) reported at least a form of IPV, Verbal abuse was the most prevalent form of IPV reported by participants (73 %, n = 56). Women who were younger were more likely to report verbal and sexual assault at p < 0.05. A shorter length of intimate relationship was significantly associated with sexual assault at p < 0.05. Sexual assault, verbal and physical abuse were significantly associated with higher mean score on the Brief Psychiatric Rating Scale at p = 0.01. The study highlighted the high rate of various forms of IPV among women with schizophrenia. Sexual assault, verbal and physical abuse were strongly associated with psychopathology. There is a need to identify risk of IPV among this vulnerable group by routine enquiry by clinicians' and plan therapy accordingly. Holistic management is needed in management of victims in their care.

Pertussis in adults and adolescents could be reduced by replacing traditional tetanus and diphtheria (Td) boosters with reduced-antigen-content diphtheria-tetanus-acellular pertussis (dTpa) vaccines. This study evaluated the administration of dTpa-IPV (dTpa-inactivated poliovirus) in adults ten years after they received a booster dose of either dTpa-IPV, dTpa+IPV or Td-IPV in trial NCT01277705. Open multicentre, phase IV study (www.clinicaltrials.govNCT01323959) in which healthy adults, who had received a previous dose of dTpa-IPV, dTpa+IPV or Td-IPV ten years earlier, received a single decennial booster dose of dTpa-IPV (Boostrix-polio, GlaxoSmithKline Vaccines). Blood samples were collected before and one month after booster vaccination. Antibody concentrations against all vaccine antigens were measured and reactogenicity and safety were assessed. A total of 211 subjects (mean age 50.3 years) received vaccination of whom 201 were included in the according-to-protocol cohort for immunogenicity. Before the decennial dTpa-IPV booster, ≥71.0% subjects were seroprotected/seropositive against all vaccine antigens. One month after the booster dose, all subjects were seroprotected against tetanus and poliovirus types 2 and 3; ≥95.7% subjects were seroprotected against diphtheria and ≥98.3% against poliovirus type 1. Anti-pertussis booster responses for the various antigens were observed in ≥76.5% (pertussis toxoid; PT), ≥85.1% (filamentous haemagglutinin; FHA) and ≥63.2% (pertactin; PRN) of subjects. During the 4-day follow-up, the overall incidence of local AEs was 71.6%, 75.0% and 72.2% in dTpa-IPV, dTpa+IPV and Td-IPV groups, respectively. Pain was the most frequent solicited local adverse event (AE; ≥62.7% subjects) and fatigue the most frequent solicited general AE (≥18.5%). No serious AEs were reported during the study. A booster dose of dTpa-IPV was immunogenic and well tolerated in adults who had received a booster dose of either dTpa-IPV, dTpa+IPV or Td-IPV, ten years previously and supports the repeated administration of dTpa-IPV.

Malcoe, Lorraine Halinka; Duran, Bonnie M; Montgomery, Juliann M

2004-01-01

Background Intimate partner violence (IPV) against women is a global public health problem, yet data on IPV against Native American women are extremely limited. We conducted a cross-sectional study of Native American women to determine prevalence of lifetime and past-year IPV and partner injury; examine IPV in relation to pregnancy; and assess demographic and socioeconomic correlates of past-year IPV. Methods Participants were recruited from a tribally-operated clinic serving low-income pregnant and childbearing women in southwest Oklahoma. A self-administered survey was completed by 312 Native American women (96% response rate) attending the clinic from June through August 1997. Lifetime and past-year IPV were measured using modified 18-item Conflict Tactics Scales. A socioeconomic index was created based on partner's education, public assistance receipt, and poverty level. Results More than half (58.7%) of participants reported lifetime physical and/or sexual IPV; 39.1% experienced severe physical IPV; 12.2% reported partner-forced sexual activity; and 40.1% reported lifetime partner-perpetrated injuries. A total of 273 women had a spouse or boyfriend during the previous 12 months (although all participants were Native American, 59.0% of partners were non-Native). Among these women, past-year prevalence was 30.1% for physical and/or sexual IPV; 15.8% for severe physical IPV; 3.3% for forced partner-perpetrated sexual activity; and 16.4% for intimate partner injury. Reported IPV prevalence during pregnancy was 9.3%. Pregnancy was not associated with past-year IPV (odds ratio = 0.9). Past-year IPV prevalence was 42.8% among women scoring low on the socioeconomic index, compared with 10.1% among the reference group. After adjusting for age, relationship status, and household size, low socioeconomic index remained strongly associated with past-year IPV (odds ratio = 5.0; 95% confidence interval: 2.4, 10.7). Conclusions Native American women in our sample experienced exceptionally high rates of lifetime and past-year IPV. Additionally, within this low-income sample, there was strong evidence of socioeconomic variability in IPV. Further research should determine prevalence of IPV against Native American women from diverse tribes and regions, and examine pathways through which socioeconomic disadvantage may increase their IPV risk.

Background Intimate partner violence (IPV) is a significant health problem that has been associated with HIV infection in numerous studies. We aimed to systematically review the literature on relationships between IPV and HIV in order to describe the prevalence of IPV in people with HIV, the prevalence of HIV in people experiencing IPV, the association between IPV and HIV, and evidence regarding mechanisms of risk and interventions. Methods Data sources were 10 electronic databases and reference lists. Studies were included if they reported data on the relationship between IPV and HIV. All records were independently reviewed by two authors at the stages of title and abstract review and full text review. Any abstract considered eligible by either reviewer was reviewed in full, and any disagreement regarding eligibility of full texts or data extracted was resolved by discussion. Results 101 articles were included. Experiencing IPV and HIV infection were associated in unadjusted analyses in most studies, as well as in adjusted analyses in many studies. The findings of qualitative and quantitative studies assessing potential mechanisms linking IPV and HIV were variable. Few interventions have been assessed, but two identified in this review were promising in terms of preventing IPV, though not HIV infection. Conclusions Experiencing IPV and HIV infection tend to be associated in unadjusted analyses, suggesting that IPV screening and linkage with relevant programs and services may be valuable. It is unclear whether there is a causal association between experiencing IPV and HIV infection. Research should focus on defining parameters of IPV which are relevant to HIV infection, including type of IPV and period of exposure and risk, on assessing potential mechanisms, and on developing and assessing interventions which build on the strengths of existing studies.

Image-data transmission from one site to another through public network is usually characterized in term of privacy, authenticity, and integrity. In this paper, we first describe a general scenario about how image is delivered from one site to another through a wide-area network (WAN) with security features of data privacy, integrity, and authenticity. Second, we give the common implementation method of the digital imaging and communication in medicine (DICOM) image communication software library with IPv6/IPv4 for high-speed broadband Internet by using open-source software. Third, we discuss two major security-transmission methods, the IP security (IPSec) and the secure-socket layer (SSL) or transport-layer security (TLS), being used currently in medical-image-data communication with privacy support. Fourth, we describe a test schema of multiple-modality DICOM-image communications through TCP/IPv4 and TCP/IPv6 with different security methods, different security algorithms, and operating systems, and evaluate the test results. We found that there are tradeoff factors between choosing the IPsec and the SSL/TLS-based security implementation of IPv6/IPv4 protocols. If the WAN networks only use IPv6 such as in high-speed broadband Internet, the choice is IPsec-based security. If the networks are IPv4 or the combination of IPv6 and IPv4, it is better to use SSL/TLS security. The Linux platform has more security algorithms implemented than the Windows (XP) platform, and can achieve better performance in most experiments of IPv6 and IPv4-based DICOM-image communications. In teleradiology or enterprise-PACS applications, the Linux operating system may be the better choice as peer security gateways for both the IPsec and the SSL/TLS-based secure DICOM communications cross public networks.

Intimate partner violence (IPV) has garnered increasing public and academic attention in the past several decades. Theories about the causes, prevention, and intervention for IPV have developed in complexity. This article provides an overview of the historical roots of IPV, as well as a description and critique of historical and contemporary theories of IPV causes and women's responses to IPV. This is followed by a discussion of the most current theoretical developments and application of critical theories to the problem of IPV. The article concludes with theoretically based implications for nursing practice and research with women who are experiencing IPV.

Objectives Intimate partner violence (IPV) is a significant public health problem in South Africa. However, limited research exists on IPV during pregnancy and the postpartum period in South Africa. The purpose of this study is to describe the prevalence, rates and correlates of IPV among South African women during pregnancy and the first nine months postpartum. Methods Data are from a longitudinal study with women recruited during pregnancy between 2008 and 2010 at a public clinic in Durban. We used a modified version of the World Health Organization’s IPV scale to estimate prevalence and rates of IPV during pregnancy, at four months postpartum and nine months postpartum and we used logistic regression to assess the correlates of IPV during this time. Results More than 20% of all women experienced at least one act of physical, psychological or sexual IPV during pregnancy. Nearly one-quarter of all women experienced at least one act of physical, psychological or sexual IPV during the first nine months postpartum. Psychological IPV was the most prevalent type of IPV during pregnancy and the first four months postpartum. Age and previous violence within the relationship were associated with IPV during pregnancy and IPV during the postpartum period. Conclusions The high levels of IPV during pregnancy and the postpartum period highlight the need to develop screening and intervention strategies specifically for this time. Further, women should be screened not only for physical violence but also psychological violence given that psychological violence may result in distinct negative consequences. PMID:24889116

The Age-IPV Curve: Changes in Intimate Partner Violence Perpetration during Adolescence and Young Adulthood

Johnson, Wendi L.; Giordano, Peggy C.; Manning, Wendy D.; Longmore, Monica A.

2014-01-01

Research on intimate partner violence (IPV) has evolved over the last decade with increasing interest in how IPV develops over adolescence and young adulthood. Studies examining patterns of IPV over time have generally focused on victimization with less attention to temporal shifts in perpetration. While it is generally assumed that IPV peaks during young adulthood, this has not been empirically verified and documented. Additionally, prior longitudinal analyses of IPV have focused on identifying trajectories and their accompanying risk factors, with less attention given to within-individual change in IPV experiences across and within relationships. Drawing on five waves of data from the Toledo Adolescent Relationships Study (TARS), we examined patterns of the perpetration of IPV among a diverse sample of adolescents and young adults (51.1% female, 63.9% non-Hispanic White, 24.6% non-Hispanic Black, 11.5% Hispanic) spanning the ages of 13–28 years (N = 1,164). Analyses demonstrated that IPV patterns deviate from the age-crime curve, with women’s involvement in IPV increasing, while their involvement in other antisocial behaviors is decreasing. Traditional behavioral and psychological risk factors (delinquency, alcohol and drug use, depressive symptoms) accounted for some of the age variation in IPV for men, but these factors did not account for age variation in IPV among women. Relationship risk factors including frequency of disagreements, trust, jealousy, validation and self-disclosure, however, accounted for substantial portions of the age-IPV perpetration relationship for male and female youth. These findings reinforce recent calls for prevention efforts that focus on the development and maintenance of healthy relationships. PMID:25081024

2013-08-01

To describe the referral patterns and utilization of on-site intimate partner violence (IPV) services in both inpatient and outpatient settings at a large urban children's hospital. Retrospective review of case records from IPV victims referred to an on-site IPV counselor between September 2005 and February 2010. Descriptive statistics were used to examine IPV victim demographics, number of referrals per hospital department, referral source (type of staff member), time spent by IPV counselor for initial consultation, and services provided to IPV victims. A total of 453 unique referrals were made to the IPV counselor: 81% were identified by universal screening and 19% by risk-based screening. Thirty-six percent of IPV victims were referred from primary care clinics; 26% from inpatient units; 13% from outpatient subspecialty clinics; 12.5% from the emergency department; 5% from the Child Protection Program; and 4% were employee self-referrals. Social workers generated the most referrals (55%), followed by attending physicians (17%), residents (13%), nurses (7%), and other individuals (self-referrals) (4%). The median initial IPV intervention required 42 minutes. Supportive counseling and safety planning were the services most often utilized by IPV victims. IPV screening can be successfully integrated in both inpatient and outpatient settings by a multidisciplinary group of hospital staff. Most referrals were generated by universal screening outside of the primary care setting. IPV victims generally desired supportive counseling and safety planning over immediate housing relocation. Many IPV screening opportunities were missed by using verbal screening alone. Copyright © 2013 Elsevier Ltd. All rights reserved.

To determine the prevalence of non-violent, gender-based forms of maltreatment of women by husbands and in-laws [i.e., gender-based household maltreatment (GBHM)] during pregnancy and postpartum; to clarify the role of GBHM in compromising infant health, and whether this role extends beyond that previously observed for intimate partner violence (IPV). Cross-sectional, quantitative data were collected from women (ages 15-35) seeking immunizations for their infants <6 months of age (N = 1061) in urban health centers in Mumbai, India. Logistic regression models were constructed to assess associations between maternal abuse (perinatal IPV, in-law violence and GBHM) and recent infant morbidity (diarrhea, respiratory distress, fever, colic and vomiting). More than one in four women (28.4%) reported IPV during their recent pregnancy and/or during the postpartum period, 2.6% reported perinatal violence from in-laws, and 49.0% reported one or more forms of perinatal GBHM. In adjusted regression models that included all forms of family violence and maltreatment, perinatal GBHM remained significantly associated with infant morbidity (AORs 1.4-1.9); perinatal IPV and in-law violence ceased to predict infant morbidity in models including GBHM. Findings indicate that non-violent expressions of gender inequity (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care during pregnancy) are more strongly associated with poor infant health than physical or sexual violence from husbands or in-laws in urban India. These results strongly suggest the need to expand the conception of gender inequities beyond IPV to include non-violent forms of gendered mistreatment in considering their impact on infant health.

It is unclear whether there is variation in the impact of intimate partner violence (IPV) on child peer problems, and which individual and environmental factors might predict such variation. This study uses data from 7,712 children (3,974, 51.5% boys) aged 4 from the Avon Longitudinal Study of Parents and Children (ALSPAC). Children were cross-categorized based on exposure to IPV from birth to 3 years, and mother-rated peer problems at age 4, into 4 groups: Resilient, Non-resilient, Vulnerable and Competent. Between-group differences in maternal depression, maternal life events, parenting, attachment, and temperament were analyzed, and these variables were also examined as predictors of group membership. Girls were more likely to be identified as resilient. In contrast to the non-resilient group, resilient boys were less emotional, had more secure attachment to their mothers, more interaction with their mothers’ partner, and their mothers reported fewer life events. For girls, the resilient group was less emotional, more sociable, and their mothers reported less depression. Temperament played a stronger role in resilience for girls than boys. There are sex differences in predictors of resilience to IPV within the peer problems outcome domain, which suggests that different approaches to intervention may be needed to foster resilience in boys and girls exposed to IPV.

To determine the prevalence and types of intimate partner violence (IPV) during pregnancy, factors linked with IPV, and effects of IPV on maternal-fetal outcomes. In a prospective observational study at a tertiary care hospital in Delhi, India, 400 women at 20-28 weeks of pregnancy were screened for IPV between December 2013 and April 2015. The women completed a detailed questionnaire and were followed up until delivery. Overall, 49 (12.3%) women experienced IPV during pregnancy. The most prevalent type of IPV was emotional (43/400 [10.7%]), followed by physical (40/400 [10.0%]) and sexual (7/400 [1.8%]). The most prevalent factor triggering IPV was intimate partner's desire for a son (17/49 [34.7%]). Women and their intimate partners were older in the IPV group than in the control group, and duration of marriage was longer (P<0.05 for all). Multigravidity, lower socioeconomic status, low education level of intimate partner, and partners' addiction were more common in the IPV group (P<0.05 for all). Obstetric outcomes were similar in both groups. Depression was diagnosed in 19 (46.3%) women affected by IPV. IPV was documented in approximately 12% of participants. Population-based surveys need to be done to investigate further. © 2016 International Federation of Gynecology and Obstetrics.

China was declared polio-free in 2000 but continues to record cases of vaccine-associated-poliomyelitis and vaccine-derived-poliovirus outbreaks. Two pilot safety studies and two larger immunogenicity trials evaluated the non-inferiority of IPV (Poliorix™, GSK Vaccines, Belgium) versus OPV in infants and booster vaccination in toddlers primed with either IPV or OPV in China. In pilot safety studies, 25 infants received 3-dose IPV primary vaccination (Study A, www.clinicaltrial.gov NCT00937404) and 25 received an IPV booster after priming with three OPV doses (Study B, NCT01021293). In the randomised, controlled immunogenicity and safety trial (Study C, NCT00920439), infants received 3-dose primary vaccination with IPV (N=541) or OPV (N=535) at 2,3,4 months of age, and a booster IPV dose at 18-24 months (N=470, Study D, NCT01323647: extension of study C). Blood samples were collected before and one month post-dose-3 and booster. Reactogenicity was assessed using diary cards. Serious adverse events (SAEs) were captured throughout each study. Study A and B showed that IPV priming and IPV boosting (after OPV) was safe. Study C: One month post-dose-3, all IPV and ≥ 98.3% OPV recipients had seroprotective antibody titres towards each poliovirus type. The immune response elicited by IPV was non-inferior to Chinese OPV. Seroprotective antibody titres persisted in ≥ 94.7% IPV and ≥ 96.1% OPV recipients at 18-24 months (Study D). IPV had a clinically acceptable safety profile in all studies. Grade 3 local and systemic reactions were uncommon. No SAEs were related to IPV administration. Trivalent IPV is non-inferior to OPV in terms of seroprotection (in the Chinese vaccination schedule) in infant and toddlers, with a clinically acceptable safety profile.

With the goal of understanding the true extent of intimate partner violence (IPV), researchers have put tremendous effort over the past 20 years developing, revising, and assessing IPV screening instruments. The enhancements made in IPV instrumentation reflect our improved understanding of the nature of IPV. Unfortunately, as is often the case…

This study examined the factors affecting a women's initial intimate partner violence (IPV)-specific health care seeking event which refers to the first health care seeking as a result of IPV in a lifetime. Data were collected using the Life History Calendar method in the Tokyo metropolitan area from 101 women who had experienced IPV. Discrete-time survival analysis was used to assess the time to initial IPV-specific health care seeking. IPV-related injury was the most significant factor associated with increased likelihood of seeking IPV-specific health care seeking for the first time. In the presence of a strong effect of formal help seeking, physical and sexual IPV were no longer significantly related to initial IPV-specific health care seeking. The results suggest some victims of IPV may not seek health care unless they get injured. The timing of receiving health care would be important to ensure the health and safety of victims. © The Author(s) 2014.

Research on risk factors for men's perpetration of intimate partner violence (IPV) has shown a high correlation with problem alcohol use. Additional studies, however, indicate that the alcohol-IPV link is neither simple nor necessarily direct and that a range of factors may moderate this relationship. Using a national, community-based sample of 255 men, the present study examined the moderating effects of ambivalent sexism (i.e., hostile and benevolent sexism) on the relationship between alcohol use and IPV perpetration. The findings show that both greater alcohol consumption and high hostile sexism are positively associated with IPV perpetration, and that hostile sexism moderates the alcohol-IPV relationship for perpetration of physical IPV, but not for psychological IPV. Moreover, high levels of alcohol consumption have a greater impact on physical IPV perpetration for men low in hostile sexism than for men high in hostile sexism, lending support to the multiple threshold model of the alcohol-IPV link. Implications of the findings for prevention, intervention, and future research are discussed. © The Author(s) 2015.

Background Understanding the past-year prevalence of male-perpetrated intimate partner violence (IPV) and risk factors is essential for building evidence-based prevention and monitoring progress to Sustainable Development Goal (SDG) 5.2, but so far, population-based research on this remains very limited. The objective of this study is to compare the population prevalence rates of past-year male-perpetrated IPV and nonpartner rape from women’s and men’s reports across 4 countries in Asia and the Pacific. A further objective is to describe the risk factors associated with women’s experience of past-year physical or sexual IPV from women’s reports and factors driving women’s past-year experience of partner violence. Methods and findings This paper presents findings from the United Nations Multi-country Study on Men and Violence in Asia and the Pacific. In the course of this study, in population-based cross-sectional surveys, 5,206 men and 3,106 women aged 18–49 years were interviewed from 4 countries: Cambodia, China, Papua New Guinea (PNG), and Sri Lanka. To measure risk factors, we use logistic regression and structural equation modelling to show pathways and mediators. The analysis was not based on a written plan, and following a reviewer’s comments, some material was moved to supplementary files and the regression was performed without variable elimination. Men reported more lifetime perpetration of IPV (physical or sexual IPV range 32.5%–80%) than women did experience (physical or sexual IPV range 27.5%–67.4%), but women’s reports of past-year experience (physical or sexual IPV range 8.2%–32.1%) were not very clearly different from men’s (physical or sexual IPV range 10.1%–34.0%). Women reported much more emotional/economic abuse (past-year ranges 1.4%–5.7% for men and 4.1%–27.7% for women). Reports of nonpartner rape were similar for men (range 0.8%–1.9% in the past year) and women (range 0.4%–2.3% in past year), except in Bougainville, where they were higher for men (11.7% versus 5.7%). The risk factor modelling shows 4 groups of variables to be important in experience of past-year sexual and/or physical IPV: (1) poverty, (2) all childhood trauma, (3) quarrelling and women’s limited control in relationships, and (4) partner factors (substance abuse, unemployment, and infidelity). The population attributable fraction (PAF) was largest for quarrelling often, but the second greatest PAF was for the group related to exposure to violence in childhood. The relationship control variable group had the third highest PAF, followed by other partner factors. Currently married women were also more at risk. In the structural model, a resilience pathway showed less poverty, higher education, and more gender-equitable ideas were connected and conveyed protection from IPV. These are all amenable risk factors. This research was cross-sectional, so we cannot be sure of the temporal sequence of exposure, but the outcome being a past-year measure to some extent mitigates this problem. Conclusions Past-year IPV indicators based on women’s reported experience that were developed to track SDG 5 are probably reasonably reliable but will not always give the same prevalence as may be reported by men. Report validity requires further research. Interviews with men to track past-year nonpartner rape perpetration are feasible and important. The findings suggest a range of factors are associated with past-year physical and/or sexual IPV exposure; of particular interest is the resilience pathway suggested by the structural model, which is highly amenable to intervention and explains why combining economic empowerment of women and gender empowerment/relationship skills training has been successful. This study provides additional rationale for scaling up violence prevention interventions that combine economic and gender empowerment/relationship skills building of women, as well as the value of investing in girls’ education with a view to long-term violence reduction.

Intimate partner violence (IPV) against women constitutes a major public health problem. Antenatal care is considered a window of opportunity to disclose and to communicate about IPV. However, little is known about how women from different ethnic backgrounds wish to communicate about their experiences with IPV during pregnancy in antenatal care. The aim of the present study was to explore how women from different ethnic backgrounds experienced IPV and what their recommendations were about how midwives should communicate about IPV in antenatal care. Qualitative individual interviews with eight women who had experienced IPV during pregnancy were conducted and analysed using thematic analysis. The participants were purposively recruited from three crisis shelters in South-East Norway. The participants either had immigrant backgrounds (n = 5) or were ethnic Norwegians (n = 3). All participants received antenatal care by a midwife. Although none of the participants were asked about IPV during antenatal care, they wished to talk about their experiences. Most participants felt that it would be important for the midwife to make them aware that they were victims of violence. Participants offered different suggestions on how and when midwives should talk about IPV. Facilitators to talk about IPV with the midwife were a good relationship with and the trustworthiness of the midwife, information about possible negative health outcomes for the newborn owing to IPV and knowing that the midwife could help them. The main barriers to talk about IPV with the midwife were that the participants were accompanied by their husbands during antenatal care, fear that the Child Welfare Service would take away their children after disclosure and cultural acceptance of violence. Participants with immigrant backgrounds also experienced difficulties in talking about IPV owing to their limited language skills. They thought that professionally trained interpreters with experience of IPV could overcome this barrier. Even though none of the participants were asked about IPV in antenatal care, they offered different suggestions on how and when midwives should talk about IPV. Participants irrespective of their ethnical backgrounds perceived antenatal care as a key area to facilitate disclosure of IPV. Midwives' communication and strategic skills to address IPV are crucial for help-seeking women. Training midwives' skills in culture-sensitive communication might help to overcome cultural barriers to talk about violence.

Childhood maltreatment and intimate partner violence in dissociative disorder patients.

Childhood maltreatment (CM) is a risk factor for subsequent intimate partner violence (IPV) in adulthood, with high rates of retrospectively reported CM among IPV victims and perpetrators. A theorized mechanism of the link between CM and IPV is dissociation. Dissociation may allow perpetrators of violence to remain emotionally distant from their behavior and minimize empathy toward those they victimize, enabling them to commit acts of violence similar to their own experiences. Indeed, elevated rates of dissociation and dissociative disorders (DD) have been found among IPV survivors and perpetrators. In addition, in pilot studies, DD clinicians have reported high levels of violent behavior among DD patients. The present study investigates IPV among DD patients with Dissociative Identity Disorder and Dissociative Disorder Not Otherwise Specified, a group with CM rates of 80-95% and severe dissociative symptoms. DD clinicians reported on rates of CM and IPV among 275 DD patients in outpatient treatment. DD patients also completed a self-report measure of dissociation. Analyses assessed the associations between CM typologies and IPV, as well as trait dissociation and IPV. Physical and emotional child abuse were associated with physical IPV, and childhood witnessing of domestic violence (DV) and childhood neglect were associated with emotional IPV. The present study is the first to provide empirical support for a possible CM to adult IPV developmental trajectory among DD patients. Future research is needed to better understand the link between CM and IPV among those with trauma and DD.

Women experiencing intimate partner violence (IPV) navigate complex, dangerous decisions. Tailored safety information and safety planning, typically provided by domestic violence service providers, can prevent repeat IPV exposure and associated adverse health outcomes; however, few abused women access these services. The Internet represents a potentially innovative way to connect abused women with tailored safety planning resources and information. The purpose of this study was to compare safety and mental health outcomes at baseline, 6 months, and 12 months among abused women randomized to: (1) a tailored, Internet-based safety decision aid; or (2) control website (typical safety information available online). Multistate, community-based longitudinal RCT with one-to-one allocation ratio and blocked randomization. Data were collected March 2011-May 2013 and analyzed June-July 2015. Currently abused Spanish- or English-speaking women (N=720). A tailored Internet-based safety decision aid included priority-setting activities, risk assessment, and tailored feedback and safety plans. A control website offered typical safety information available online. Primary outcomes were decisional conflict, safety behaviors, and repeat IPV; secondary outcomes included depression and post-traumatic stress disorder. At 12 months, there were no significant group differences in IPV, depression, or post-traumatic stress disorder. Intervention women experienced significantly less decisional conflict after one use (β= -2.68, p=0.042) and greater increase in safety behaviors they rated as helpful from baseline to 12 months (12% vs 9%, p=0.033) and were more likely to have left the abuser (63% vs 53%, p=0.008). Women who left had higher baseline risk (14.9 vs 13.1, p=0.003) found more of the safety behaviors they tried helpful (61.1% vs 47.5%, p<0.001), and had greater reductions in psychological IPV ((11.69 vs 7.5, p=0.001) and sexual IPV (2.41 vs 1.25, p=0.001) than women who stayed. Internet-based safety planning represents a promising tool to reduce the public health impact of IPV. Copyright © 2017 American Journal of Preventive Medicine. Published by Elsevier Inc.

In Nigeria, there is paucity of information on the IPV burden and experience among young women in courtship and dating relationships. This study assesses the prevalence and correlates of IPV in female undergraduate and postgraduate students in a tertiary institution. The study was a cross-sectional survey. A four-stage sampling technique was used to select 1,100 undergraduate and 255 postgraduate female students from the University of Ibadan, Nigeria. Data was collected using a 43-item self-administered structured questionnaire. Descriptive statistics and multivariate analyses were carried out at 0.05 level of significance. The life-time prevalence of IPV was 42.3% (postgraduate: 34.5%, undergraduate: 44.1%; P < 0.05). Lifetime experience of psychological, physical and sexual IPV were 41.8%, 7.9% and 6.6% respectively. Recent experience (within the previous 12 months) of violence was also more frequently reported by respondents who had a previous history of physical (62.5%) (OR = 2.65; 95% CI: 2.02-3.49) and sexual (53.2%) (OR = 1.63; 95% CI:1.12-2.35) violence than respondents who had no such history. Postgraduate (OR = 0.64; 95% CI: 0.46-0.87) and married (OR = 0.53; 95% CI: 0.35-0.78) students were less likely to have experienced IPV than undergraduate and single students respectively. Students who smoked (OR = 2.46; 95% CI: 1.58-3.83); consumed alcohol (OR = 2.36; 95% CI: 1.82- 3.06); and with history of interparental violence (OR = 2.40; 95% CI: 1.88- 3.07) had a higher likelihood of experiencing violence than students who were not exposed to these behaviors. Adverse effects (such as the inability to concentrate) of IPV on academic performance were reported by 10.3% of victims. The prevalence of IPV was high. There is the urgent need for interventions that will reduce vulnerability by addressing modifiable risk factors like smoking and alcohol consumption. Interventions should also encourage seeking health care following violence to reduce its consequences.

Oral and Inactivated Poliovirus Vaccines in the Newborn: A review

Background Oral poliovirus vaccine (OPV) remains the vaccine-of-choice for routine immunization and supplemental immunization activities (SIAs) to eradicate poliomyelitis globally. Recent data from India suggested lowerthanexpected immunogenicity of an OPV birth dose, prompting a review of the immunogenicity of OPV or inactivated poliovirus vaccine (IPV) when administered at birth. Methods We evaluated the seroconversion and reported adverse events among infants given a single birth dose (given ≤7 days of life) of OPV or IPV through a systematic review of published articles and conference abstracts from 1959-2011 in any language found on PubMed, Google Scholar, or reference lists of selected articles. Results 25 articles from 13 countries published between1959 and 2011 documented seroconversion rates in newborns following an OPV dose given within the first seven days of life. There were 10 studies that measured seroconversion rates between 4 and 8 weeks of a single birth dose of TOPV, using an umbilical cord blood draw at the time of birth to establish baseline antibody levels. The percentage of newborns who seroconverted at 8 weeks range 6-42% for poliovirus type 1, 2-63% for type 2, and 1-35% for type 3). For mOPV type 1, seroconversion ranged from 10-76%; mOPV type 3, the range was 12-58%; and for the one study reporting bOPV, it was 20% for type 1 and 7% for type 3. There were four studies of IPV in newborns with a seroconversion rate of 8-100% for serotype 1, 15-100% for serotype 2, and 15-94% for serotype 3, measured at 4-6 weeks of life. No serious adverse events related to newborn OPV or IPV dosing were reported, including no cases of acute flaccid paralysis. Conclusions There is great variability of the immunogenicity of a birth dose of OPV for reasons largely unknown. Our review confirms the utility of a birth dose of OPV, particularly in countries where early induction of polio immunity is imperative. IPV has higher seroconversion rates in newborns and may be a superior choice in countries which can afford IPV, but there have been studies of an IPV dose for newborns. PMID:22728224

Intimate partner violence (IPV) against women is an important, yet often neglected public health issue. The existence of gender norms imbalance expressed by men's and women's attitudes in relation to power and decision-making in intimate relationships may influence the magnitude of IPV. The aim of this study was to investigate the prevalence and potential risk factors of physical, sexual and psychological IPV in young men and women in Rwanda. This population-based, cross-sectional study included a representative sample of men and women from the Southern Province of Rwanda. Face-to-face interviews were performed using the World Health Organization (WHO) questionnaire for violence exposure to estimate past year and earlier in life IPV occurrence. Risk factor patterns were analyzed by use of bi- and multivariate logistic regression. Women were, to a considerably higher extent, exposed to physical, sexual and psychological IPV than men. Of the women, 18.8% (n = 78) reported physical abuse in the past year, compared to 4.3% (n = 18) of men. The corresponding figures for women and men for sexual abuse were 17.4% (n = 71) and 1.5% (n = 6), respectively, and for psychological abuse, the corresponding figures were 21.4% (n = 92) and 7.3% (n = 32). Findings illustrate that violence against women was recurrent, as the highest frequency (>3 times) dominated in women for the various acts of all forms of violence. Identified risk factors for women's exposure to physical violence were being low educated, having poor social support, being poor and having many children. For men exposed to physical violence, no statistically significant risk factor was identified. In this setting, IPV exposure was more common in women than men in the Southern Province of Rwanda. Promotion of gender equality at the individual level is needed to make a positive difference in a relatively short term perspective. Men's lower reporting of IPV confirms women's subordinate position, but men's denial of incidents could also explain the gender role pattern.

In this study, we investigated the effect of songs that offer non-misogynous and ambivalent portrayals of intimate partner violence (IPV). Participants (N = 103) were exposed to a misogynous song about IPV, a song critical of IPV, and a song that offered an ambivalent portrayal of IPV. Our results showed positive effects of the anti-IPV song, and both positive and negative effects of the ambivalent portrayal on participants' beliefs about a violent relationship. These findings suggest that the context in which IPV is portrayed should be considered when evaluating the impact of media depicting IPV. © The Author(s) 2016.

Perceptions of Informal and Formal Coping Strategies for Intimate Partner Violence Among Gay and Bisexual Men.

2018-03-01

The prevalence of intimate partner violence (IPV) in same-sex male relationships has been reported to be at least as prevalent as is observed in female-male relationships. Though research has focused on understanding the prevalence and antecedents of IPV in male-male relationships, there is a paucity of data describing perceptions of coping strategies adopted by gay and bisexual men who may experience IPV. Ten focus group discussions were conducted with 64 gay and bisexual men in Atlanta, Georgia, between September 2013 and November 2013. Focus groups examined perceptions of how gay and bisexual men would respond to IPV and the IPV-coping services they would utilize. Thematic analysis was conducted to identify themes that describe how gay and bisexual men perceive existing IPV services and how they would use these services, if gay and bisexual men were to experience IPV. The results indicate that men experiencing IPV in male-male relationships do not have adequate access to IPV services that are tailored to their unique needs. As a result, there is a strong reliance on informal sources of support. Services are urgently needed to meet the unique needs of men experiencing IPV in same-sex relationships.

The fraction of Internet traffic carried over IPv6 continues to grow rapidly. IPv6 support from network hardware vendors and carriers is pervasive and becoming mature. A network infrastructure upgrade often offers sites an excellent window of opportunity to configure and enable IPv6. There is a significant overhead when setting up and maintaining dual-stack machines, so where possible sites would like to upgrade their services directly to IPv6 only. In doing so, they are also expediting the transition process towards its desired completion. While the LHC experiments accept there is a need to move to IPv6, it is currently not directly affecting their work. Sites are unwilling to upgrade if they will be unable to run LHC experiment workflows. This has resulted in a very slow uptake of IPv6 from WLCG sites. For several years the HEPiX IPv6 Working Group has been testing a range of WLCG services to ensure they are IPv6 compliant. Several sites are now running many of their services as dual-stack. The working group, driven by the requirements of the LHC VOs to be able to use IPv6-only opportunistic resources, continues to encourage wider deployment of dual-stack services to make the use of such IPv6-only clients viable. This paper presents the working group’s plan and progress so far to allow sites to deploy IPv6-only CPU resources. This includes making experiment central services dual-stack as well as a number of storage services. The monitoring, accounting and information services that are used by jobs also need to be upgraded. Finally the VO testing that has taken place on hosts connected via IPv6-only is reported.

To describe the relationship between exposure to physical and/or sexual intimate partner violence (IPV) and indicators of antenatal care (ANC) service utilization among Honduran women of reproductive age. Data from the 2011-2012 Honduras Demographic and Health Survey were analyzed to describe the relationship between self-reported exposure to IPV and two ANC outcomes: (1) sufficient ANC visits (defined by the Honduran Ministry of Health as five or more visits) and (2) early ANC initiation (within the first trimester). Multiple logistic regression was used to estimate effects of physical and sexual IPV on the outcomes, controlling for women's age, education, literacy, residence, household size, religion, parity, wealth, husband's age, and husband's education. Of women who were married, had at least one living child 5 years or younger, and completed the IPV module (N = 6 629), 13.5% of them reported any physical IPV, and 4.1% reported both physical and sexual IPV. There was no significant association between IPV and early ANC; however, a significant relationship between IPV and sufficient ANC was found. Women who experienced any physical IPV (adjusted odds ratios (aOR) = 1.25; 95% confidence interval (CI): 1.00-1.56) or sexual IPV (aOR = 1.53; 95% CI: 1.08-2.16) were, respectively, 25% and 53% more likely to receive insufficient ANC. Honduras has one of highest rates of interpersonal violence of any nation in the world. In Honduras, IPV is a contributor to this broader category of interpersonal violence as well as a risk factor for insufficient ANC. Our findings suggest that universal IPV screening during ANC as well as future initiatives aimed at reducing IPV might improve ANC utilization in the country.

The polio eradication endgame strategic plan calls for the sequential removal of Sabin poliovirus serotypes from the trivalent oral poliovirus vaccine (tOPV), starting with type 2, and the introduction of ≥1 dose of inactivated poliovirus vaccine (IPV), to maintain an immunity base against poliovirus type 2. The global removal of oral poliovirus type 2 was successfully implemented in May 2016. However, IPV supply constraints has prevented introduction in 21 countries and led to complete stock-out in >20 countries. We conducted a literature review and contacted corresponding authors of recent studies with fractional-dose IPV (fIPV), one-fifth of intramuscular dose administered intradermally, to conduct additional type 2 immunogenicity analyses of two fIPV doses compared with one full-dose IPV. Four studies were identified that assessed immunogenicity of two fIPV doses compared to one full-dose IPV. Two fractional doses are more immunogenic than 1 full-dose, with type 2 seroconversion rates improving between absolute 19-42% (median: 37%, p<0.001) and relative increase of 53-125% (median: 82%), and antibody titer to type 2 increasing by 2-32-fold (median: 10-fold). Early age of administration and shorter intervals between doses were associated with lower immunogenicity. Overall, two fIPV doses are more immunogenic than a single full-dose, associated with significantly increased seroconversion rates and antibody titers. Two fIPV doses together use two-fifth of the vaccine compared to one full-dose IPV. In response to the current IPV shortage, a schedule of two fIPV doses at ages 6 and 14weekshas been endorsed by technical oversight committees and has been introduced in some affected countries.

2006-12-01

This study provides preliminary evidence of the relationship between perceived racial discrimination and intimate partner violence (IPV) and how these exposures interact to affect the mental and physical health of Black women. The exposures of lifetime perceived racial discrimination and IPV were found to be highly associated. Furthermore, women who reported both exposures showed a notably higher prevalence of anxiety and nonspecific physical health symptoms compared with women who reported either or neither exposure. To appropriately respond to the health needs of Black women, it is essential that women's many stressors be considered simultaneously.

The current aim is to examine the prevalence of intimate partner violence (IPV) among Thai women residing in Sweden and its association with mental health. We also investigate the potential influence of social isolation and social capital regarding the association between IPV and mental health outcome. A public health questionnaire in Thai was distributed by post to the entire population of Thai women, aged 18-64, residing in two regions in Sweden since 2006. Items included aspects related to IPV (physical/sexual/emotional), sociodemographic background, physical health, mental health (GHQ-12), social isolation, and social capital (i.e. social trust/participation). The response rate was 62.3% (n=804). Prevalence of lifetime reported IPV was 22.1%, with 20.5% by a previous partner and 6.7% by a current partner. Previous IPV exposure was significantly related to current IPV exposure, and all IPV exposure measures were significantly related to poor mental health. However, Thai women experiencing IPV by a current partner were more at risk for poor mental health than Thai women with previous or without any experience of IPV. Also, among all women exposed to IPV, those with trust in others and without exposure to social isolation seemed to have partial protection against the adverse mental health consequences associated with IPV. Most Thai women had never been exposed to IPV, and after migrating to Sweden, women had lower IPV exposure than in Thailand. However, the increased risk for poor mental health among those Thai women exposed to IPV suggests the need for supportive measures and targeted interventions to prevent further injuries and adverse health consequences. Although poor mental health in Thai women represents an obstacle for integration, the potential resilience indicated in the group with high social trust and without exposure to social isolation suggests that such aspects be included in the program designed to facilitate integration.

Intimate partner violence (IPV), including physical, sexual, emotional, and economic violence, has profound immediate and long-term effects on individuals and communities worldwide. To date, few studies have focused on couples' reporting of IPV. The aim of this article is to present the results of a survey of couples' reporting of IPV and the individual, interpersonal, and social correlates of IPV in northern Tanzania. Four hundred fifty couples from Karatu District, Tanzania, completed a questionnaire measuring attitudes on gender norms and relations, men's experience of childhood trauma, and men's perpetration and women's experience of IPV. We found high levels of acceptance and experience of IPV: 72% of men justified a husband's perpetration of IPV, and 54% of men and 76% of women said that a woman should tolerate violence to keep her family together. The majority of women had ever experienced IPV (77.8%), and 73.6% and 69% had experienced IPV in the past 12 and 3 months, respectively. Men were significantly less likely to report that they had committed IPV: 63.6% ever, 48.9% in the past 12 months, and 46.2% in the past 3 months. Multivariate logistic regression found that younger men, men who reported gender inequitable attitudes, childhood trauma, multiple sexual partners, and alcohol use were significantly more likely to report IPV perpetration in the past 3 months. Younger women, and women with low levels of education and reported food shortages were significantly more likely to report IPV in the past 3 months. These results indicate that social and individual acceptance and justification of IPV are common. Experience of violence persists over time in many relationships. This study demonstrates the need for interventions that address individual-, interpersonal-, and community-level determinants of IPV, including attitudes regarding gender equity, exposure to violence as children and intergenerational violence, lack of education, and poverty.

This study explored the differential profiles of drug-addicted patients according to gender and the perpetration of intimate partner violence (IPV). The study assessed a sample of 127 drug-addicted patients (84 male and 43 female) who sought treatment. Information about socio-demographic and consumption characteristics, IPV, psychopathological symptoms, personality characteristics and maladjustment variables was obtained. Four groups were created according to gender and the presence or absence of the perpetration of IPV: (a) men with IPV (n=41), (b) women with IPV (n=29), (c) men without IPV (n=43), and (d) women without IPV (n=14). The four groups were compared in terms of all of studied variables. There were significant differences between the groups in the severity of the addiction and personality characteristics. In general, the drug-addicted patients with associated IPV perpetration exhibited greater scores for nearly all of the studied variables, independent of gender. Moreover, the differences among groups were more strongly related to perpetration of IPV than to the gender of the patients. According to the results obtained, treatment programs for drug addiction are a suitable context for identifying the presence of IPV, but IPV is typically unnoticed in addiction treatment programs. The implications of these results for future research and clinical practice are discussed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Avoidance coping is consistently linked with negative mental health outcomes among women experiencing intimate partner violence (IPV). This study extended the literature examining the potentially mediating role of avoidance coping strategies on both mental health and substance use problems to a highly generalizable, yet previously unexamined population (i.e., women experiencing bidirectional IPV) and examined multiple forms of IPV (i.e., psychological, physical, and sexual) simultaneously. Among a sample of 362 women experiencing bidirectional IPV, four separate path models were examined, one for each outcome variable. Avoidance coping mediated the relationships between psychological and sexual IPV victimization and the outcomes of PTSD symptom severity, depression severity, and drug use problems. Findings indicate nuanced associations among IPV victimization, avoidance coping, and mental health and substance use outcomes. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Intimate partner violence (IPV) is a major public health concern. Thus, it is vital to identify factors, such as individuals' personality traits, that may place men and women at risk for experiencing IPV. This study used data from Wave 4 of the National Longitudinal Study of Adolescent Health (N = 7,187), to examine the association between the Big Five personality traits and IPV perpetration and victimization among men and women. High openness, extraversion, and neuroticism emerged as the three most important risk factors associated with IPV. Although risk factors were found to be relatively similar for IPV perpetration and IPV victimization, some gender differences emerged, showing that extraversion was only connected to IPV for women but not for men. The present findings may bear important considerations for researchers and practitioners working with individuals and couples affected by IPV.

Research has documented significant relationships between posttraumatic stress disorder (PTSD), aggression, and intimate partner violence (IPV). Most of these studies have focused on men and measured violence by self-report. This study examined (a) the association between PTSD and general aggression among women, (b) the association between IPV and PTSD among married and/or cohabitating couples, and (c) the concordance between self and collateral reports of IPV. One hundred twenty participants provided information about PTSD symptoms and general aggression toward others, and 43 married and/or cohabitating couples provided information about PTSD and IPV. Women with PTSD reported more general aggression, IPV perpetration, and IPV victimization. Collateral informants of those with and without PTSD did not differ significantly in their report of IPV. Concordance between participants and spouses or partners was low to moderate. These results are discussed within the context of extant IPV literature.

Intimate partner violence (IPV) is a global public health and human rights problem that causes physical, sexual and psychological harms to men and women. IPV includes physical aggression, sexual coercion, psychological abuse and/or controlling behaviours perpetrated by a current or previous intimate partner in a heterosexual or same-sex relationship. IPV affects both men and women, but women are disproportionately affected with nearly one third reporting IPV during their lifetime. Physical and sexual harms from IPV include injury, increased risk for sexually transmitted diseases, pregnancy complications and sometimes death. Psychological consequences include depression, anxiety, posttraumatic stress disorder, substance abuse, impulsivity and suicidality and non-specific physical complaints thought to be related to the traumatic nature and chronic stress of IPV. Children who witness IPV are also negatively impacted in the short and long term. This paper reviews prevalence, risk factors, adverse effects and current evidence-based mental health treatment advice for IPV victims.

Intimate partner violence (IPV) is a crime that is present in all countries, seriously impacts victims, and demands a great deal of time and resources from the criminal justice system. The current study examined the use of the Spousal Assault Risk Assessment Guide, 2nd ed. (SARA; Kropp, Hart, Webster, & Eaves, 1995), a structured professional judgment risk assessment and management tool for IPV, by police officers in Sweden over a follow-up of 18 months. SARA risk assessments had significant predictive validity with respect to risk management recommendations made by police, as well as with recidivism as indexed by subsequent contacts with police. Risk management mediated the association between risk assessment and recidivism: High levels of intervention were associated with decreased recidivism in high risk cases, but with increased recidivism in low risk cases. The findings support the potential utility of police-based risk assessment and management of IPV, and in particular the belief that appropriately structured risk assessment and management decisions can prevent violence.

This follow-up study assessed the 5-year persistence of vaccine-induced antibodies (Td-IPV or DT-IPV) and the immune response to a booster dose of DTaP-IPV. This was an open-label, parallel-group (two arms), multicentre trial performed at 44 study sites in France. Children aged 11-13 years, of either sex, who received Td-IPV (Revaxis(®)) and DT-IPV (DT Polio(®)) vaccines at 6 years of age in one previous open-label trial with no further vaccination against diphtheria, tetanus, pertussis or poliomyelitis, were enrolled. All participants received a single intramuscular booster dose (0.5mL) of DTaP-IPV vaccine (Tetravac-Acellulaire(®)). Study endpoints were based on antibody persistence and post-booster immune responses. Safety was monitored throughout the study. Descriptive statistics were used for all analyses. Of the 758 children included in the previous study, 274 were included in this follow-up study; 129 had previously been vaccinated with Td-IPV, and 145 had previously received DT-IPV. At least 96.5% of participants in both groups presented an anti-diphtheria and anti-tetanus concentration ≥0.01IU/mL, and anti-poliovirus types 1-3 titres≥8 (1/dilution). Following vaccination with DTaP-IPV, anti-diphtheria and anti-tetanus antibody concentrations ≥0.1IU/mL and anti-poliovirus types 1-3 antibody titres ≥8 (1/dilution) were achieved in all participants. DTaP-IPV was well tolerated in this study. There were no serious adverse events during the study, and no participant withdrew because of adverse events. The present study confirmed the long-term immunity conferred by Td-IPV when given as a booster dose, and supports the use of Td-IPV as a second booster at 6 years of age in children previously vaccinated against diphtheria, tetanus and poliomyelitis types 1-3.

Physical intimate partner violence (IPV) and STIs, including HIV, are highly prevalent in east Africa. While we have some evidence about women's experience with physical IPV, little is known about men's experience with physical IPV, particularly in sub-Saharan Africa. Our objective was to examine, in Tanzanian male migrant plantation residents, the prevalence of, and associations among, experience and enactment of physical IPV and prevalent STI/HIV. Data from a cross-sectional survey of male plantation residents (n=158) in northern Tanzania were analysed to estimate prevalence of physical IPV experience and enactment. We assessed associations between IPV and sexual risk behaviours, and serodiagnosis of HIV, herpes simplex virus type-2 (HSV-2) and syphilis. Overall, 30% of men had experienced and/or enacted physical IPV with their main sexual partner: 19% of men had ever experienced physical IPV with their main sexual partner; 22% had enacted physical IPV with their main sexual partner. Considering overlaps in these groups, 11% of all participants reported reciprocal (both experienced and enacted) physical IPV. 9% of men were HIV seropositive, 51% were HSV-2 seropositive and 10% were syphilis seropositive-54% had at least one STI. Men who reported reciprocal physical IPV had increased odds of STI/HIV (adjusted OR (AOR) 8.85, 95% CI 1.78 to 44.6); the association retained statistical significance (AOR 14.5, 95% CI 1.4 to 147.0) with sexual risk behaviours included in the multivariate model. Men's physical IPV experience and enactment was common among these migrant plantation residents. Men reporting reciprocal physical IPV had significantly increased odds of prevalent STI/IPV, and we hypothesise that they have unstable relationships. Physical IPV is an important risk factor for STI/HIV transmission, and programmatic activities are needed to prevent both. Published by the BMJ Publishing Group Limited.

Increasingly recognized as a distinct form of childhood maltreatment, children's exposure to intimate partner violence (IPV) has been shown to be associated with an array of negative psychosocial outcomes, including elevated risk for additional violence over the life course. Although studies have identified child exposure to IPV as a predictor of IPV perpetration in adulthood, no review has critically evaluated the methodology of this quantitative work. The present study examines the association between childhood exposure to IPV and the perpetration of IPV in adulthood based on a systematic review of the literature from inception to January 4, 2016. Databases searched included Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, Sociological Abstracts and ERIC. Database searches were complemented with backward and forward citation chaining. Studies were critically appraised using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 5601 articles identified by the search, 19 studies were included for data extraction. Sixteen of these studies found that child exposure to IPV was significantly and positively associated with adult IPV perpetration; three studies reported null findings. The methodological quality of the studies was low. Work thus far has tended to focus on child exposure to physical IPV and the perpetration of physical IPV within heterosexual contexts. In addition, measures of child exposure to IPV vary in their classification of what exposure entails. We critically discuss the strengths and limitations of the existing evidence and the theoretical frameworks informing this work. Copyright © 2017 Elsevier Ltd. All rights reserved.

HIV assisted partner services (APS) are a notification and testing strategy for sex partners of HIV-infected index patients. This cluster-randomized controlled trial secondary data analysis investigated whether history of intimate partner violence (IPV) modified APS effectiveness and risk of relationship dissolution. Eighteen HIV testing and counseling sites in Kenya randomized to provide immediate APS (intervention) or APS delayed for 6 weeks (control). History of IPV was ascertained at study enrollment and defined as reporting ever experiencing physical or sexual IPV. Those reporting IPV in the month before enrollment were excluded. We tested whether history of IPV modified intervention effectiveness and risk of relationship dissolution using population-averaged Poisson and log-binomial generalized estimating equation models. Exploratory analyses investigated associations between history of IPV and events that occurred after HIV diagnosis using log-binomial generalized estimating equation models. The study enrolled 1119 index participants and 1286 partners. Among index participants, 81 (7%) had history of IPV. History of IPV did not modify APS effectiveness in testing, newly diagnosing, or linking partners to care. History of IPV did not modify the association between receiving immediate APS and relationship dissolution during the study. Among participants who had not experienced IPV in the last month but had experienced IPV in their lifetimes, our results suggest that APS is an effective and safe partner notification strategy in Kenya. As APS is scaled up in different contexts, these data support including those reporting past IPV and closely monitoring adverse events.

 The development of a Sabin strain-based inactivated poliovirus vaccine (Sabin-IPV) is imperative to protecting against vaccine-associated paralytic poliomyelitis in developing countries.  In this double-blinded, parallel-group, noninferiority trial, eligible infants aged 60-90 days were randomly assigned in a ratio of 1:1 to receive either 3 doses of Sabin-IPV or Salk strain-based IPV (Salk-IPV) at 30-day intervals and a booster at the age of 18 months. Immunogenicity and safety were assessed on the basis of a protocol.  Of 1438 infants, 1200 eligible infants were recruited and received either Sabin-IPV or Salk-IPV. From the Sabin-IPV and Salk-IPV groups, 570 and 564 infants, respectively, completed the primary immunization and formed the per-protocol population. The seroconversion rates of the participants who received Sabin-IPV were 100%, 94.9%, and 99.0% (types I, II, and III, respectively), and those of the participants who received Salk-IPV were 94.7%, 91.3%, and 97.9% 1 month after the completion of primary immunization. An anamnestic response for poliovirus types I, II, and III was elicited by a booster in both groups. Except in the case of fever, other adverse events were similar between the 2 groups.  The immune response induced by Sabin-IPV was not inferior to that established with Salk-IPV. © The Author 2016.

To examine trends in the prevalence of domestic violence since 1997, 1 year prior to the introduction of legislative countermeasures and accompanying services in South Korea, and to analyze what socio-demographic characteristics of perpetrators contribute to spousal violence and whether there were any changes in risk factors over time. This study used two sets of nationally representative household samples: married or cohabiting couples of 1,540 from the 1999 national survey and 3,269 from the 2010 National Survey of Domestic Violence. Frequency analysis was used to measure the prevalence of intimate partner violence (IPV), and cross-tabulation, correlation, and logistic regression analyses were used to look for socio-demographic risk factors of spousal physical violence and patterns of change over time. The frequency analysis showed that the IPV prevalence dropped by approximately 50%, from 34.1% in 1999 to 16.5% in 2010, though it was still higher than many other countries. The cross-tabulation and logistic regression analyses suggested that men with low socio-demographic characteristics were generally more violent, though this tendency did not apply to women. Instead, younger women seemed to be more violent than older women. Last, different levels of household income were associated with different levels of IPV in 2010, but no linear trend was detected. In this study, IPV prevalence trends and risk factors of two different time periods were discussed to provide implications for tackling the IPV problem. Future countermeasures must build on understanding about men with low socio-demographic status and younger women, who were more violent in marital relationships. © The Author(s) 2015.

The intersection of intimate partner violence against women and HIV/AIDS: a review.

2008-12-01

The objective of this study was to review original research on the intersection of violence against women by intimate partners and risk for HIV infection and highlight opportunities for new research and programme development. Seventy-one articles presenting original, peer-reviewed research conducted with females aged 12 years and older in heterosexual relationships during the past decade (1998-2007) were reviewed. Studies were eligible for inclusion if they addressed intimate partner violence (IPV) against women and HIV/AIDS as mutual risk factors. The prevalence of IPV and HIV infection among women varies globally, but females remain at elevated risk for both IPV and sexually transmitted/HIV infection, independently and concurrently. Comparisons between sero-negative and -positive women varied by geographic region; African HIV-positive women reported higher rates of victimisation while findings were inconsistent for HIV-positive women in the USA. Studies among various populations support the existence of a temporally and biologically complex relationship between HIV risk, lifetime exposure to violence and substance use, which are further complicated by gender and sexual decision-making norms. A possible link between violence-related post traumatic stress disorder and comorbid depression on immunity to HIV acquisition and HIV disease progression warrants further investigation. Sexual risk related to IPV works through both male and female behaviour, physiological consequences of violence and affects women across the lifespan. Further physiological and qualitative research is needed on the mechanisms of enhanced transmission; prospective studies are critical to address issues of causality and temporality. Prevention efforts should focus on the reduction of male-perpetrated IPV and male HIV risk behaviours in intimate partnerships.

Objectives To differentiate between forms of intimate partner violence (IPV) (victim only, perpetrator only, or participating in reciprocal violence) and examine risk profiles and pregnancy outcomes. Design Prospective Setting Washington, DC, July 2001 to October 2003 Sample 1044 high-risk African-American pregnant women who participated in a randomized controlled trial to address IPV, depression, smoking, and environmental tobacco smoke exposure. Methods Multivariable linear and logistic regression Main outcome measures Low and very low birth weight, preterm and very preterm birth Results 5% of women were victims only, 12% were perpetrators only, 27% participated in reciprocal violence, and 55% reported no IPV. Women reporting reciprocal violence in the past year were more likely to drink, use illicit drugs, and experience environmental tobacco smoke exposure and were less likely to be very happy about their pregnancies. Women reporting any type of IPVwere more likely to be depressed than those reporting no IPV. Women experiencing reciprocal violence reported highest levels of depression. Women who were victims of IPV were more likely to give birth prior prematurely and deliver low and very low birth weight infants. Conclusions We conclude that women were at highest risk for pregnancy risk factors when they participated in reciprocal violence and thus might be at higher risk for long-term consequences, but women who were victims of intimate partner violence were more likely to show proximal negative outcomes like preterm birth and low birth weight. Different types of interventions may be needed for these two forms of intimate partner violence. PMID:23786367

Acceptability of Family Violence: Underlying Ties Between Intimate Partner Violence and Child Abuse.

Intimate partner violence (IPV) and child abuse (CA) are two forms of family violence with shared qualities and risk factors, and are forms of violence that tend to overlap. Acceptability of violence in partner relationships is a known risk factor in IPV just as acceptability of parent-child aggression is a risk factor in CA. We hypothesized that these acceptability attitudes may be linked and represent the expression of a general, underlying nonspecific acceptance of violence in close family relationships. The sample involved 164 male IPV offenders participating in a batterer intervention program. Implicit measures, which assess constructs covertly to minimize response distortions, were administered to assess acceptability of partner violence against women and acceptability of parent-child aggression. To determine whether acceptability attitudes regarding both forms of violence were related to a higher order construct tapping general acceptance of family violence, Bayesian confirmatory factor analyses were conducted. Findings supported a hierarchical (bifactor) model with a general factor expressing a nonspecific acceptance of family violence, and two specific factors reflecting acceptability of violence in intimate partner and parent-child relationships, respectively. This hierarchical model supporting a general acceptance of violence in close family relationships can inform future research aiming to better understand the connections between IPV and CA.

Intimate partner violence (IPV) is a complex and global phenomenon that requires a multi-perspective analysis. Nevertheless, the number of neuroscientific studies conducted on this issue is scarce as compared with studies of other types of violence, and no neuroimaging studies comparing batterers to other criminals have been conducted. Thus, the main aim of this study was to compare the brain functioning of batterers to that of other criminals when they are exposed to IPV or general violence pictures. An fMRI study was conducted in 21 batterers and 20 other criminals while they observed IPV images (IPVI), general violence images (GVI) and neutral images (NI). Results demonstrated that batterers, compared with other criminals, exhibited a higher activation in the anterior and posterior cingulate cortex and in the middle prefrontal cortex and a decreased activation in the superior prefrontal cortex to IPVI compared to NI. The paired t-test comparison between IPVI and GVI for each group showed engagement of the medial prefrontal cortex, the posterior cingulate and the left angular cortices to IPVI in the batterer group only. These results could have important implications for a better understanding of the IPV phenomenon. © The Author (2016). Published by Oxford University Press.

Slc:Wistar rats have been the only strain used in Japan for purpose of evaluating a national reference vaccine for the Sabin-derived inactivated polio vaccine (sIPV) and the immunogenicity of sIPV-containing products. However, following the discovery that the Slc:Wistar strain was genetically related to the Fischer 344 strain, other "real" Wistar strains, such as Crlj:WI, that are available worldwide were tested in terms of their usefulness in evaluating the immunogenicity of the past and current lots of a national reference vaccine. The response of the Crlj:WI rats against the serotype 1 of sIPV was comparable to that of the Slc:Wistar rats, while the Crlj:WI rats exhibited a higher level of response against the serotypes 2 and 3. The immunogenic potency units of a national reference vaccine determined using the Slc:Wistar rats were reproduced on tests using the Crlj:WI rats. These results indicate that a titer of the neutralizing antibody obtained in response to a given dose of sIPV cannot be directly compared between these two rat strains, but that, more importantly, the potency units are almost equivalent for the two rat strains.

This randomized (1:1), double-blind, multicenter study, included 4,968 healthy infants to receive either the 11-valent pneumococcal protein D (PD)-conjugate study vaccine or the hepatitis A vaccine (HAV) (control) at 3, 4, 5, and 12-15 months of age. The three-dose primary course of both vaccines was co-administered with combined hexavalent DTPa-HBV-IPV/Hib vaccine. The pneumococcal PD-conjugate study vaccine did not impact the immune response of co-administered hexavalent vaccine and the control HAV vaccine induced seropositivity (antibodies >or=15 mIU/mL) in all infants. The incidence of solicited symptoms was higher with the 11-valent pneumococcal PD-conjugate study vaccine, yet similar to that induced by concomitant DTPa-HBV-IPV/Hib vaccine. Overall, the reactogenicity and safety profile of the 11-valent pneumococcal PD-conjugate vaccine when co-administered with the hexavalent DTPa-HBV-IPV/Hib vaccine, as well as the immunogenicity of the co-administered hexavalent vaccine, were consistent with previous reports for the licensed DTPa-HBV-IPV/Hib and pneumococcal conjugate vaccines.

Rates of reported child maltreatment nearly doubled in Canada over the period 1998-2003, an increase that reflects growing awareness of the harmful effects of an expanding array of parental behaviors, including corporal punishment, lack of supervision, and exposure to intimate partner violence (IPV). Some of these situations may benefit from voluntary family support programs outside of the child welfare system. Analyzing a sample of 11,807 investigations, this paper compares cases where the sole concern is exposure to IPV, or hitting a child, or neglect, or other forms of investigated maltreatment. Situations where exposure to IPV or potentially abusive hitting were the sole reason for investigation presented with fewer risk factors and were less likely to lead to ongoing child welfare interventions compared to other maltreatment investigations. While situations involving alleged neglect presented a higher risk profile and elicited a more intensive child welfare response than did exposure to IPV or hitting, opportunities for alternative services were nevertheless identified. The study also found that visible minority families were overrepresented in cases involving hitting and that Aboriginal families were overrepresented in cases involving neglect. Overall the findings support the development of alternative response programs in Canada.

Using a mixed methodology, the present study compared men's and women's perceived benefits and emotional reactions with participating in research that inquired about child maltreatment and intimate partner violence (IPV) victimization and perpetration. Participants consisted of 703 college students (357 women, 346 men), ages 18 to 25 who reported on their childhood maltreatment, adolescent and adult IPV victimization and perpetration, and their reactions (perceived benefits and emotional effects) to participating. Participants' reactions to participating were assessed using quantitative scales, as well as open-ended written responses that were content coded by researchers. Women reported more personal benefits from research, whereas men and women reported similar levels of emotional reactions to research participation. Furthermore, greater frequencies of child maltreatment and IPV victimization were related to higher levels of emotional reactions. Common self-identified reasons for emotional reactions (e.g., not liking to think about abuse in general, personal victimization experiences) and benefits (e.g., reflection and awareness about oneself, learning about IPV) were also presented and analyzed. These data underscore the importance of future research that examines the behavioral impact of research participation utilizing longitudinal and in-depth qualitative methodologies. Findings also highlight the potential psychoeducational value of research on understanding the reasons underlying participants' benefits and emotional effects. © The Author(s) 2015.

African American women who are victims of intimate partner violence (IPV) often rely on faith when exposed to IPV; however, the role of the faith community in the lives of IPV victims is less clear. This study uses a community-based approach to examine the role of the faith community in addressing IPV in heterosexual relationships in North Minneapolis where rates of poverty and IPV among African Americans are disproportionately high compared to other cities in Minnesota. Five focus group discussions (FGDs) were held with 34 lay and secular leaders of mixed genders in the North Minneapolis community. FGDs were evaluated using a grounded theory method of analysis. Discussions revealed that some faith leaders effectively identified IPV as a community issue and intervened but that many remained silent or were not well trained to address the issue safely. Faith-based solutions were identified to address IPV in the African American community and included the faith community speaking openly about IPV, developing programs for unmarried and adolescent couples, and coordinating services with secular IPV support organizations.

Intimate partner violence (IPV) has significant impacts on workers and workplaces. This paper examines the experiences of gender and sexual minority (GSM) people in this context. People aged 15 and older completed an online survey on the impacts of IPV at work, and brief health and life quality questions. Of 7918 respondents, 8.5% (n = 672) indicated GSM status. We examined IPV exposure, health and IPV-related work impacts by overall GSM status, and separately by sexual orientation, and gender. GSM respondents were significantly more likely to report IPV and that the IPV continued at or near their workplace, impeded their ability to get to work, negatively impacted their work performance, and their co-workers; they also reported poorer mental health and life quality. While women were significantly more likely to report IPV and various negative work and health outcomes, being a sexual minority had additional independent negative effects. No differences in willingness to disclose IPV were found. Workplace responses to IPV should account for the additional impacts and barriers faced by GSM people in disclosing abuse and seeking help.

BACKGROUND Research has examined how physical and sexual intimate partner violence (IPV) victimization increases sexual risk behavior, yet research is lacking on 1) the effect of psychological IPV on sexual risk behavior and 2) factors through which psychological IPV may be linked to sexual risk behavior. METHODS The current study examined the relationship between psychological IPV and sexual risk behavior controlling for other forms of IPV (i.e., physical and sexual) in a sample of 186 HIV-negative community women currently experiencing IPV. Further, this study examined the potential mediating effects of four posttraumatic stress disorder (PTSD) symptom severity clusters (i.e., re-experiencing, avoidance, numbing, and hyperarousal) on this relationship. FINDINGS Results revealed that greater severity of psychological IPV was uniquely and directly related to greater sexual risk behavior. Additionally, of the four PTSD symptom severity clusters, only avoidance symptom severity mediated the relationship between psychological IPV and sexual risk behavior. CONCLUSION Implications for addressing psychological IPV and PTSD to improve women’s sexual health outcomes are discussed. PMID:25498762

The live-attenuated oral polio vaccine (OPV) will be no longer used when wild poliovirus (WPV) eliminating in worldwide, according to GPEI (the Global Polio Eradication Initiative) Reports. It is planning to replace OPV by Sabin-based inactivated poliovirus vaccine (sIPV) in developing countries, with purpose of reducing of the economic burden and maintaining of the appropriate antibody levels in population. It studied serial fractional doses immunized by intradermal injection (ID) in rats, to reduce consume of antigen and financial burden, maintaining sufficient immunogenicity; Methods: Study groups were divided in 4 groups of dose gradient, which were one-tenth (1/10), one-fifth (1/5), one-third (1/3) and one-full dose (1/1), according to the volume of distribution taken from the same batch of vaccine (sIPV). Wistar rats were injected intradermally with the needle and syringe sing the mantoux technique taken once month for 3 times. It was used as positive control that intramuscular inoculation (IM) was injected with one-full dose (1/1) with same batch of sIPV. PBS was used as negative control. Blood samples were collected via tail vein. After 30 d with 3 round of immunization, it analyzed the changes of neutralization antibody titers in the each group by each immunization program end; Results: The results of seroconversion had positive correlation with different doses in ID groups. The higher concentration of D-antigen (D-Ag) could conduct higher seroconversion. Furthermore, different types of viruses had different seroconversion trend. It showed that the geometric mean titers (GMTs) of each fractional-dose ID groups increased by higher concentration of D-Ag, and it got significant lower than the full-dose IM group. At 90 th days of immunization, the GMTs for each poliovirus subtypes of fractional doses were almost higher than 1:8, implied that it could be meaning positive seroprotection titer for polio vaccine types, according to WHO suggestion; Conclusions: The fractional dose with one-fifth (1/5) could be used by intradermal injection to prevent poliovirus infection, if there were more human clinical detail research consistent with this findings in rats.

Intimate partner violence screening and the comparative effects of screening mode on disclosure of sensitive health behaviours and exposures in clinical settings.

Detecting sensitive health information in clinical settings is of scientific and practical importance. The purpose of this study was to determine whether mode of screening influenced disclosure of intimate partner violence (IPV) in patterns similar to other forms of sensitive information. This cross sectional study was designed to compare effects of face-to-face vs computer self-assessment for sensitive health information on disclosure rates. Multivariate logistic regression was used for the analysis. Data were collected in 2012 from 639 eligible African American consenting women receiving services in women, infants and children (WIC) clinics. Women were randomized to complete assessments of sensitive exposures via computer-assisted self-interview (CASI) or face-to-face interview (FTFI). Those with complete information were included in the analysis (n = 616). Of 39 sensitive health exposures, reporting was higher for FTFI than CASI for exposure to IPV (7 of 7 outcomes), tobacco use (2 of 3 outcomes) and reproductive health care (2 of 3 outcomes). For example, face-to-face improved disclosure of IPV in the last year (adjusted odds ratios [aOR] = 2.27; 95% CI = 1.60-3.21) and any drug, tobacco or alcohol in the last week (aOR = 1.39; 95% CI = 1.00-1.93). Trained personnel may enhance disclosure above computer-based assessments for IPV for African American women receiving public assistance through The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) Propensities to disclose sexual health behaviour and drug use by CASI may not apply to IPV in this population. The context and personal motivations influence women's decision to disclose IPV. Copyright © 2016 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

OBJECTIVE To investigate the prevalence of violence involving intimate partners among women visiting Canadian family practices and to assess participants’ attitudes toward future use of computer-assisted screening for violence and other health risks. DESIGN Self-report via written survey. SETTING Group family practice clinic in inner-city Toronto, Ont. PARTICIPANTS Women patients at least 18 years old who were fluent in English. MAIN OUTCOME MEASURES Responses to questions about violence selected from the Abuse Assessment Screen and the Partner Violence Screen. Participants’ attitudes toward computer-assisted screening as measured by the Computerized Lifestyle Assessment Scale (1 to 5) in the domains of benefits, privacy—barriers, interaction—barriers, and interest. RESULTS Responses were received from 202 patients, 144 of whom were in current or recent relationships and completed the section on intimate-partner violence (IPV). The overall prevalence of IPV in current or recent relationships was 14.6%. Emotional abuse was reported by 10.4%, threat of violence by 8.3%, and physical or sexual violence by 7.6% of respondents. Emotional abuse was significantly associated with threat of violence and physical or sexual violence (P≤.001). Analysis of responses to questions on computerized screening revealed that participants generally perceived it would have benefits (mean score 3.6) and were very interested in it (mean score 4.3). Those who reported experiencing IPV rated the benefits of computerized screening significantly higher than respondents without IPV experiences did (t2.3, df142, P < .05). Participants were “not sure” about barriers (mean score 3.0). Responses were similar in the 2 groups for the domains of interest, privacy—barriers, and interaction—barriers. CONCLUSION The high rate of IPV reported by women attending family practices calls for physicians to be vigilant. Future research should examine ways to facilitate physicians’ inquiry into IPV. The positive attitudes of our participants toward interactive computer-assisted screening indicates a need for more research in this area. PMID:17872682

Safety and immunogenicity of 2 investigational formulations of diphtheria, tetanus and Haemophilus influenzae type b antigens of the combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliomyelitis-Hib vaccine (DTPa-HBV-IPV/Hib) were evaluated in a Primary (NCT01248884) and a Booster vaccination (NCT01453998) study. In the Primary study, 721 healthy infants (randomized 1:1:1) received 3 doses of DTPa-HBV-IPV/Hib formulation A (D A T A Pa-HBV-IPV/Hib), or B (D B T B Pa-HBV-IPV/Hib) or the licensed DTPa-HBV-IPV/Hib vaccine (Infanrix hexa, GSK; control group) at 2, 3, 4 months of age. Infants were planned to receive a booster dose at 12-15 months of age with the same formulation received in the Primary study; however, following high incidence of fever associated with the investigational formulations in the Primary study, the Booster study protocol was amended and all infants yet to receive a booster dose (N = 385) received the licensed vaccine. In the Primary study, non-inferiority of 3-dose vaccination with investigational formulations compared with the licensed vaccine was not demonstrated due to anti-pertactin failing to meet the non-inferiority criterion. Post-primary vaccination, most infants had seroprotective levels of anti-diphtheria (100% of infants), anti-tetanus antigens (100%), against hepatitis B (≥ 97.5% across groups), polyribosyl-ribitol-phosphate (≥ 88.0%) and poliovirus types 1-3 (≥ 90.5%). Seropositivity rates for each pertussis antigen were 100% in all groups. Higher incidence of fever (> 38°C) was reported in infants receiving the investigational formulations (Primary study: 75.0% [A] and 72.1% [B] vs 58.8% [control]; Booster study, before amendment: 49.4% and 46.6% vs 37.4%, respectively). The development of the investigational formulations was not further pursued.

Though the technology of IPv6 network has become mature in recent years, it still takes long to dispose IPv6 in an all-round way in the internet. In this research, we have designed an IPv6 multihomed host architecture to connect both IPv6 network and 6to4 network. This paper describes a load balance mechanism that allows applications on multihomed devices to utilize the individual networks efficiently to transmit streams that could be part of a session. We experiment the relevant parameters in the IPv6 testbed environment to demonstrate its effectiveness.

A national survey of attitudes toward intimate partner violence among married women in Kazakhstan, Kyrgyzstan, and Tajikistan: Implications for health prevention and intervention.

Attitudes toward intimate partner violence (IPV) can affect the prevalence of IPV, response of victims' to IPV (e.g., whether to seek help), and the response of professionals (e.g., police, social workers, health care professionals) to IPV. Knowledge about IPV-related attitudes is essential for developing effective social work and violence-related programs. Using data from the 2005-2006 Multiple Indicator Cluster Surveys, this study examines attitudes toward IPV and socio-demographic predictors of these attitudes among married women in Kazakhstan, Kyrgyzstan, and Tajikistan. Women were asked whether they approved of a husband beating his wife: if she goes out without telling him, neglects their children, argues, refuses to have sex, and burns food. The prevalence of IPV acceptance for at least one of the five reasons varied from 12.3% in Kazakhstan to 45.3% in Kyrgyzstan and 74.5% in Tajikistan. Women who were less educated, members of Asian ethnic groups, resided in middle-class urban areas, and lived in specific regions were more likely to accept IPV. Few age differences that emerged indicated that young women were more approving of IPV. Proactive efforts are needed to confront attitudes about gender roles and IPV in Tajikistan and Kyrgyzstan.

Adverse Childhood Experiences and Criminal Propensity Among Intimate Partner Violence Offenders.

Adverse childhood experiences (ACEs), defined as exposure to abuse and adverse household events, are prevalent among certain offenders including those who commit intimate partner violence (IPV). However, it is not clear how ACEs relate to criminal propensity among IPV offenders, who have been shown to exhibit less antisociality and institutional violence than other offenders. We compared 99 male offenders with a current or previous offense of IPV with 233 non-IPV violent offenders and 103 nonviolent offenders undergoing institutional forensic assessment. This convenience sample allowed for use of extensive psychosocial records as well as study of institutional violence. IPV offenders had the highest mean ACE score and more extensive criminal propensity on some measures (violent and nonviolent criminal history and psychopathy) than both other groups. ACEs were associated with most measures of criminal propensity in the whole sample but with only one (actuarial risk of violent recidivism) in the subsample of IPV offenders. Finding that ACEs are prevalent among IPV offenders even in this sample with extensive mental illness demonstrates the robustness of this phenomenon. IPV offenders, though, are similar to other violent offenders in this respect, and there is insufficient evidence that ACEs represent a criminogenic need among IPV offenders specifically. Further research could draw from the batterer typology literature and attend to IPV offenders' broader criminal careers.

Guided by the main tenets of contemporary models of the developmental origins of health and disease, this study evaluated whether individual differences in reactivity of the hypothalamic-pituitary-adrenal (HPA) axis and Sympathetic Nervous System (SNS) moderate the effect of prenatal exposure to trauma on internalizing and externalizing behaviors during infancy. Participants were a community sample of 182 mothers (M age=25years, 43% Caucasian, 33% Black/African American, 24% Biracial/Other) and their infants (59% girls; M age=11.8months). Each mother completed questionnaires that assessed IPV experienced during pregnancy and also reported on her infant's behavior problems. Infant saliva samples (later assayed for cortisol and sAA) were collected before and after a frustrating task (i.e., arm restraint). Results revealed that the association between in utero IPV and infant internalizing behaviors was most pronounced for infants with asymmetrical HPA-SNS (i.e., high-cortisol and low-sAA) reactivity to frustration, and least pronounced for infants with symmetrical HPA-SNS (i.e., low-cortisol and low-sAA or high-cortisol and high-sAA) reactivity to frustration. Higher levels of externalizing behavior, in contrast, were associated with higher levels of prenatal IPV but unrelated to either cortisol or sAA reactivity to stress. Findings replicate documented associations between maternal IPV exposure during pregnancy and offspring risk. Moreover, findings advance our understanding of individual differences in the developmental origins of health and disease and provide additional evidence that assessing multiple stress biomarkers contributes to a more comprehensive understanding of individual vulnerability to adversity.

Psychosocial conditions such as depression, intimate partner violence (IPV), and history of childhood sexual abuse (CSA) have been associated with poor HIV-related outcomes. In India, which has the third largest HIV epidemic in the world, little is understood about the impact of psychosocial conditions on people living with HIV (PLHIV). We aimed to understand the prevalence and correlates of psychosocial conditions among PLHIV entering into HIV care at the Y.R. Gaitonde Centre for AIDS Research and Education in Chennai, India. Thirteen questions were added to the standard voluntary counseling and testing questionnaire, including the Patient Health Questionnaire-9 (a depression scale) and questions assessing for CSA and IPV. We fitted logistic regression models, stratified by gender, with psychosocial condition as the outcome of interest and substance use variables and socio-demographic variables as the correlates of interest. Three hundred and eighty-three persons were enrolled into the study; of these, 253 (66%) tested positive for HIV, including 149 men and 104 women, and were included in the models. More than one-quarter (28%) of the men and 19% of the women reported at least one psychosocial condition (probable depression, CSA, or IPV). In adjusted analysis, current alcohol use was associated with greater than two times higher odds of a psychosocial condition (Adjusted Odds Ratio = 2.24, 95% CI, 1.04-4.85) among men. In conclusion, we estimated the prevalence of probable depression, CSA, and IPV among PLHIV presenting for HIV care in southern India and found that, among male PLHIV, alcohol use was associated with a markedly higher odds of reporting a psychosocial condition. Further study is needed to characterize alcohol use among male PLHIV and the possible deleterious impact of psychosocial conditions and alcohol use on HIV-related outcomes in India.

There is growing empirical evidence for an association between childhood abuse (CA) and intimate partner violence (IPV) in adulthood. We tested whether revictimized survivors of severe to extreme severities of child sexual abuse (CSA) and severe severities of child physical abuse (CPA) differed from nonvictimized healthy controls in their trait preferences in intimate partners and their current mate choice. In a sample of 52 revictimized female patients with posttraumatic stress disorder (PTSD) after CSA/CPA and 52 female healthy controls, the validated Intimate Partner Preferences Questionnaire (IPPQ) was used to assess (a) the desirability of tenderness, dominance, and aggression traits in potential partners, and (b) the presence of these traits in their current intimate partners. Factors potentially associated with partner preference and mate choice, for example, chronicity of traumatic events and lower self-esteem, were explored. Our results showed that, in general, revictimized PTSD patients did not have a preference for dominant or aggressive partners. However, revictimized women displayed a significantly larger discrepancy than did healthy controls between their preferences for tenderness traits and their ratings of the presence of tenderness traits in their current partners. Our results indicated that revictimized patients had lower self-esteem values; however, these values were associated with higher demands for tenderness traits. Furthermore, our results revealed that compared with patients who experienced early-onset childhood abuse (CA), those who experienced later onset CA were more accepting of dominant traits in potential partners. Women who had experienced IPV rated their current partners to be overly dominant. A higher tolerance of dominance traits might increase the risk of IPV in a specific subgroup of abused women (women with a later onset of abuse experiences and experiences of IPV).

IPv4 is now officially deprecated by the IETF. A significant amount of effort has already been expended by the HEPiX IPv6 Working Group on testing dual-stacked hosts and IPv6-only CPU resources. Dual-stack adds complexity and administrative overhead to sites that may already be starved of resource. This has resulted in a very slow uptake of IPv6 from WLCG sites. 464XLAT (RFC6877) is intended for IPv6 single-stack environments that require the ability to communicate with IPv4-only endpoints. This paper will present a deployment strategy for 464XLAT, operational experiences of using 464XLAT in production at a WLCG site and important information to consider prior to deploying 464XLAT.

Intimate partner violence (IPV) is a significant cause of intentional injury among women but remains underrecognized, and its relationship to other risk factors for all-cause injury remains poorly defined. This study aimed to assess IPV and its association with alcohol abuse, illicit substance use, selected mental illnesses, and other risk factors for injury. This is a cross-sectional study of prospectively collected data among adult females admitted to a rural, Level I trauma center. Well-validated instruments assessed IPV, substance abuse, and mental illness. Bivariate relationships were assessed with χ, odds ratios, and t test analyses. Eighty-one women were enrolled; 51% reported lifetime IPV, and 31% reported past-year IPV. Both groups were significantly more likely to have a mental illness than those without a history of IPV. Those reporting lifetime IPV exposure were significantly more likely to report illicit substance use, and past-year IPV was associated with alcohol abuse (28% vs. 7.1%, p = 0.01). Participants reporting past-year IPV were significantly more likely to have a partner possessing a firearm (40% vs. 12.5%, p = 0.005). The experience of lifetime and past-year IPV among women at a Level I, rural trauma center was high, and it was significantly associated with mental illness, substance abuse, and high-risk scenarios for intentional injury including firearm ownership by a significant other. These findings inform the potential value of IPV screening and intervention and suggest that IPV, mental illness, and substance abuse should be considered associated entities in prevention and recidivism reduction efforts in the female trauma population. Prognostic study, level II; therapeutic study, level III.

Children exposed to intimate partner violence (IPV) are at increased risk of experiencing behavioral difficulties including externalizing and internalizing problems. While there is mounting evidence about mental health problems in children exposed to IPV, most of the research to date focuses on IPV exposure as a unitary, homogeneous construct. The purpose of this study was to examine the association between subtypes of IPV exposure on child functioning and presence of harm within a child welfare sample. Given the evidence of the "double whammy" effect, co-occurring IPV exposure was also examined. Using data from the Canadian Incidence Study of Reported Child Abuse and Neglect - 2008 (n=2,184) we examined whether specific IPV exposure subtypes or their co-occurrence resulted in a greater risk of child maladjustment. Information was obtained from child welfare workers' reports. Caregiver and household risk factors were also examined. Co-occurring IPV exposure resulted in the greatest risk for reported child maladjustment. Exposure to emotional IPV and direct physical IPV were significantly associated with increased risk of internalizing problems and presence of harm. Caregiver mental health and lack of social support emerged as significant risk factors for behavior problems. This study adds to the evidence that exposure to subtypes of IPV may be differentially related to child functioning. Given that risk factors and child functioning is part of the decision-making framework for case worker referrals, this study provides important preliminary evidence about how the child welfare system operates in practice with respect to sub-types of exposure to IPV. These findings suggest that intervening with children exposed to different types of IPV may require a tailored approach. Copyright © 2014. Published by Elsevier Ltd.

Women with activity limitations (ALs) are at risk for Intimate partner violence (IPV). This study examined IPV in men versus women with ALs. Data from the Canadian 1999 General Social Survey compared physical, sexual, emotional, and financial IPV from a current/expartner in 5 years for men and women with ALs compared with those without ALs. Logistic regression examined sex differences in IPV among those with ALs, adjusting for sociodemographic factors. Rates of physical (11.9% versus 7.8%; p < 0.0001), sexual (3.5% versus 1.4%; p < 0.0001), emotional (27.1% versus 17.7%; p < 0.0001), and financial (7.5% versus 3.4%; p < 0.0001) IPV were greater in women with compared with without ALs. A similar pattern was seen for men, with greater rates of physical (9.2% versus 6.6%; p = 0.006), emotional (22.6% versus 18.2%; p = 0.002), and financial (2.6% versus 1.4%; p = 0.005) IPV in men with ALs than men without ALs. Risk factors for IPV included younger age, being divorced/separated or single, and having lower income and poorer health. Women with ALs were more likely than men to experience any IPV (29.1% versus 24.9%) and more severe and more incidents of IPV. In multivariable analysis, women were no longer at greater risk for "any IPV" after adjusting for sociodemographic variables (odds ratio = 1.09; 95% confidence interval, 0.88-1.36). This is the first study to document IPV rates in men with ALs. Women with ALs were more likely to be divorced/separated, living in poverty, and in poorer health than men with ALs. These factors accounted for sex differences in IPV rates.

As perinatal HIV-infected youth become sexually active, the potential for onward transmission becomes an increasing concern. In other populations, intimate partner violence (IPV) is a risk factor for HIV acquisition. We build on this critical work by studying the role of IPV in facilitating onward transmission among HIV-infected youth-an important step toward effective intervention. Soweto, South Africa. Self-report surveys were completed by 129 perinatal HIV-infected female youth (aged 13-24 years). We calculated the IPV prevalence and used logistic models to capture the association between IPV and health outcomes known to facilitate onward HIV transmission (eg, risky sex, poor medication adherence, depression, and substance abuse). A fifth of perinatal HIV-infected participants reported physical and/or sexual IPV in the past year; one-third reported lifetime IPV. Childhood adversity was common and positively associated with IPV. Past-year physical and/or sexual IPV was positively correlated with high-risk sex [odds ratio (OR) = 8.96; 95% confidence interval (CI): 2.78 to 28.90], pregnancy (OR = 6.56; 95% CI: 1.91 to 22.54), poor medication adherence to antiretroviral therapy (OR = 5.37; 95% CI: 1.37 to 21.08), depression (OR = 4.25; 95% CI: 1.64 to 11.00), and substance abuse (OR = 4.11; 95% CI: 1.42 to 11.86). Neither past-year nor lifetime IPV was associated with viral load or HIV status disclosure to a partner. We find that IPV may increase risk for onward HIV transmission in perinatal HIV-infected youth by both increasing engagement in risky sexual behaviors and lowering medication adherence. HIV clinics should consider integrating primary IPV prevention interventions, instituting routine IPV screening, and collocating services for victims of violence.

Most studies that have examined alcohol use immediately prior to intimate partner violence (IPV) have been limited to male-to-female partner violence (MFPV) and are subject to a number of methodological limitations. We add new information concerning the relationship between alcohol involvement and severity of IPV, MFPV, and female-to-male partner violence (FMPV). We analyzed data from a 1995 U.S. national population-based survey of couples > or = 18 years old. We examined 436 couples who reported IPV and had information on alcohol involvement with IPV. We measured IPV using a revised Conflict Tactics Scale, Form R that asked respondents about 11 violent behaviors in the past year. Respondents were classified into mutually exclusive categories as having experienced mild only or mild + severe ("severe") IPV, MFPV or FMPV. Respondents were also asked if they or their partner were drinking at the time the violent behavior occurred and were classified as exposed to IPV with or without alcohol involvement. We estimated proportions, odds ratios, 95% confidence intervals, and p-values of the proposed associations, accounting for the complex survey design. Overall, 30.2% of couples who reported IPV reported alcohol involved IPV; 69.8% reported no alcohol involvement. In adjusted analyses, those reporting severe (vs. mild only) IPV were more than twice as likely to report alcohol involvement. In adjusted analyses, those reporting severe (vs. mild) MFPV or FMPV were more likely to report female but not male alcohol involvement. Though estimates were positive and strong, most confidence intervals were compatible with a wide range of estimates including no association. Our findings suggest alcohol involvement of either or both in the couple increases the risk of severe IPV. Our findings also suggest female alcohol use may play an important role in determining the severity of IPV, MFPV or FMPV.

The aim of this study was to investigate associations between maternal stress, parenting behavior, and sibling adjustment in relation to child trauma symptoms in families with and without a history of intimate partner violence (IPV). Maternal report was used to measure maternal stress and child trauma symptoms, whereas parenting behavior was assessed through an observational measure. Participants consisted of mothers with 2 school-age siblings recruited from the community. Results indicated that violent families reported higher levels of maternal stress and sibling trauma symptoms than nonviolent families, although no differences were found in parenting behavior. Sibling trauma symptoms and negative maternal behavior toward a sibling were strong predictors of trauma symptoms in younger siblings exposed to IPV but only modest predictors for older siblings. Moderator analyses showed that in IPV-affected families, the trauma symptoms of older siblings were related to the trauma symptoms of younger siblings when maternal stress was high.

Nearly 32% of women report experiencing physical violence from an intimate partner and more than 8% report being raped by a significant other in their lifetime. Young people's perceptions that their peers perpetrate relationship violence have been shown to increase the odds of self-reported perpetration. Yet, limited research has been conducted on this relationship as individuals begin to age out of adolescence. The present study sought to examine the link between the perception of peer perpetration of intimate partner violence (IPV) and self-reported IPV perpetration among a sample of predominately young adult (21-35 years) males. This study also explored the discordance between the perception of peer IPV behavior and self-reported perpetration. Data from 101 male peer dyads ( n = 202) were taken from a study on the effects of alcohol and bystander intervention in Atlanta, Georgia. Thirty-six percent ( n = 73) of men reported perpetrating physical IPV and 67% ( n = 135) reported perpetrating sexual IPV in the past 12 months. Nearly 35% ( n = 55) of the sample reported that none of their peers had perpetrated physical IPV, which contradicted their friend's self-report of physical IPV perpetration. Similarly, 68% ( n = 115) of the men perceived none of their peers to have perpetrated sexual IPV, which contradicted their friend's self-report of sexual IPV perpetration. Discordance variables were significantly associated with self-reported perpetration for both physical (χ 2 = 152.7, p < .01) and sexual (χ 2 = 164.4, p < .01) IPV. These results point to an underestimation of peer IPV perpetration among young adult males. Findings suggest a traditional social norms approach to IPV prevention, which seeks to persuade individuals that negative behaviors are less common than perceived, may not be the best approach given a significant number of men believed their friends were nonviolent when they had perpetrated violence.

Intimate partner violence around the time of pregnancy and postpartum depression: The experience of women of Bangladesh

Background and objectives Intimate partner violence (IPV) around the time of pregnancy is a serious public health concern and is known to have an adverse effect on perinatal mental health. In order to craft appropriate and effective interventions, it is important to understand how the association between IPV and postpartum depression (PPD) may differ as a function of the type and timing of IPV victimization. Here we evaluate the influence of physical, sexual and psychological IPV before, during and after pregnancy on PPD. Methods Cross-sectional survey data was collected between October 2015 and January 2016 in the Chandpur District of Bangladesh from 426 new mothers, aged 15–49 years, who were in the first six months postpartum. Multivariate logistic regression models were used to estimate the association between IPV and PPD, adjusted for socio-demographic, reproductive and psychosocial confounding factors. Results Approximately 35.2% of women experienced PPD within the first six months following childbirth. Controlling for confounders, the odds of PPD was significantly greater among women who reported exposure to physical (AOR: 1.79, 95% CI [1.25, 3.43]), sexual (AOR: 2.25, 95% CI [1.14, 4.45]) or psychological (AOR: 6.92, 95% CI [1.71, 28.04]) IPV during pregnancy as opposed to those who did not. However, both before and after pregnancy, only physical IPV evidences a direct effect on PPD. Results highlight the mental health consequences of IPV for women of Bangladesh, as well as the influence of timing and type of IPV on PPD outcomes. Conclusions and implications The findings confirm that exposure to IPV significantly increases the odds of PPD. The association is particularly strong for physical IPV during all periods and psychological IPV during pregnancy. Results reinforce the need to conduct routine screening during pregnancy to identify women with a history of IPV who may at risk for PPD and to offer them necessary support. PMID:28472056

Sexual intimate partner violence (IPV) is a public health problem worldwide. Research regarding beliefs about perpetrating sexual IPV is, however, limited. This study investigated attitudes, social influence, and self-efficacy beliefs and intentions toward perpetrating sexual IPV among Grade 8 adolescents ( M age = 13.73, SD = 1.04) in the Western Cape Province of South Africa. The study sample was taken from the baseline data of the Promoting sexual and reproductive health among adolescents in Southern and Eastern Africa (PREPARE) study, a cluster-randomized controlled trial. Young adolescents ( N = 2,199), from 42 randomly selected high schools, participated in the study and answered a paper-and-pencil questionnaire. Multivariate ANOVA were conducted to assess differences in beliefs and intention toward perpetrating sexual IPV between boys and girls, and between perpetrators and nonperpetrators. Results showed that boys were more frequently perpetrators (11.3% vs. 3.2%) and victims (13.6% vs. 6.4%) of sexual IPV than girls. Boys' attitudes toward perpetrating sexual IPV were more supportive than girls'. Boys perceived their social network to be more likely to think that putting pressure on a boyfriend or girlfriend to have sex is okay, and boys had a lower self-efficacy to refrain from pressuring a boyfriend or girlfriend to have sex compared with girls. Both boys and girls, who have perpetrated sexual IPV, had more tolerant attitude, social influence, and self-efficacy beliefs toward sexual IPV perpetration, compared with nonperpetrators. Intention not to perpetrate sexual IPV did not differ between boys and girls, or between perpetrators and nonperpetrators. Our findings suggest that interventions should address attitude and social influence beliefs regarding sexual IPV perpetration. More attention should be given to sexual IPV perpetration among boys. Given that sexual IPV victimization and perpetration are significantly linked, prevention of sexual IPV perpetration seems to be of utmost importance.

The World Health Organization recommends that, as part of the new polio endgame, a dose of inactivated poliovirus vaccine (IPV) be introduced by the end of 2015 in all countries using only oral poliovirus vaccine (OPV). Administration of fractional dose (1/5th of full dose) IPV (fIPV) intradermally may reduce costs, but its administration is cumbersome with BCG needle and syringe. We evaluated performance of two newly developed intradermal-only jet injectors and compared the immune response induced by fIPV with that induced by full-dose IPV. Children between 12 and 20 months of age, who had previously received two doses of OPV, were enrolled in Camaguey, Cuba. Subjects received a single dose of IPV (either full-dose IPV intramuscularly with needle and syringe or fIPV intradermally administered with one of two new injectors or with BCG needle or a conventional needle-free injector). Serum was tested for presence of poliovirus neutralizing antibodies on day 0 (pre-IPV) and on days 3, 7 and 21 (post-vaccination). Complete data were available from 74.2% (728/981) subjects. Baseline median antibody titers were 713, 284, and 113 for poliovirus types 1, 2, and 3, respectively. Seroprevalence at study end were similar across the intervention groups (≥ 94.8%). The immune response induced with one new injector was similar to BCG needle and to the conventional injector; and superior to the other new injector. fIPV induced significantly lower boosting response compared to full-dose IPV. No safety concerns were identified. One of the two new injectors demonstrated its ability to streamline intradermal fIPV administration, however, further investigations are needed to assess the potential contribution of fIPV in the polio endgame plan.

Background HIV status disclosure is a central strategy in HIV prevention and treatment but in high prevalence settings women test disproportionately and most often during pregnancy. This study reports intimate partner violence (IPV) following disclosure of HIV test results by pregnant women. Methods In this cross sectional study we interviewed 1951 postnatal women who tested positive and negative for HIV about IPV experiences following HIV test disclosure, using an adapted WHO questionnaire. Multivariate regression models assessed factors associated with IPV after disclosure and controlled for factors such as previous IPV and other known behavioural factors associated with IPV. Results Over 93% (1817) disclosed the HIV results to their partners (96.5% HIV− vs. 89.3% HIV+, p<0.0001). Overall HIV prevalence was 15.3%, (95%CI:13.7–16.9), 35.2% among non-disclosers and 14.3% among disclosers. Overall 32.8% reported IPV (40.5% HIV+; 31.5% HIV− women, p = 0.004). HIV status was associated with IPV (partially adjusted 1.43: (95%CI:1.00–2.05 as well as reporting negative reactions by male partners immediately after disclosure (adjusted OR 5.83, 95%CI:4.31–7.80). Factors associated with IPV were gender inequity, past IPV, risky sexual behaviours and living with relatives. IPV after HIV disclosure in pregnancy is high but lower than and is strongly related with IPV before pregnancy (adjusted OR 6.18, 95%CI: 3.84–9.93). Conclusion The study demonstrates the interconnectedness of IPV, HIV status and its disclosure with IPV which was a common experience post disclosure of both an HIV positive and HIV negative result. Health services must give attention to the gendered nature and consequences of HIV disclosure such as enskilling women on how to determine and respond to the risks associated with disclosure. Efforts to involve men in antenatal care must also be strengthened. PMID:25350001

Recommended infant vaccination in Korea includes DTaP-IPV and Hib vaccines administered as separate injections. In this randomized, open, controlled study we assessed the non-inferiority of immunogenicity of DTaP-IPV//Hib pentavalent combination vaccine (Pentaxim™) compared with licensed DTaP-IPV and Hib (PRP~T) vaccines. We enrolled 418 healthy Korean infants to receive either separate DTaP-IPV and Hib vaccines (n = 206) or the pentavalent DTaP-IPV//Hib (n = 208) vaccine at 2, 4, 6 months of age. Antibodies to all components were measured before the first vaccination and one month after the third, and safety was assessed after each vaccination including recording of reactions by parents. We confirmed the non-inferiority of DTaP-IPV//Hib compared with DTaP-IPV and Hib vaccines; 100% of both groups achieved seroprotection against D, T, IPV and PRP~T, and 97.5%-99.0% demonstrated seroresponses to pertussis antigens. Antibody levels were similar in both groups, except for those to the Hib component, PRP~T. In separate and combined groups geometric mean concentrations of anti-PRP~T antibodies were 23.9 and 11.0 μg/mL, respectively, but 98.3% and 97.4% had titers ≥ 1 μg/mL, indicative of long-term protection. All vaccines were well tolerated, with no vaccine-related serious adverse event. Both groups had similar safety profiles, but the combined vaccine group had fewer injection site reactions. The immunological non-inferiority and similar safety profile of DTaP-IPV//Hib vaccine to separate DTaP-IPV and Hib vaccines, with the advantage of fewer injections and injection site reactions, supports the licensure and incorporation of DTaP-IPV//Hib into the Korean national vaccination schedule (Clinical trial registry, NCT01214889).

Minority Stress and Intimate Partner Violence Among Gay and Bisexual Men in Atlanta.

Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations. Few studies have examined the plausible relationship between minority stress and IPV among men who have sex with men. This study examines the associations between IPV and three indicators of minority stress: internalized homophobia, sexuality-based discrimination, and racism, in a large venue-based sample of gay and bisexual men from Atlanta, USA. Each of the minority stress measures was found to be significantly associated with increased odds of self-reporting any form of receipt of IPV. Significant associations were also identified between perpetration of IPV and minority stressors, with most types of IPV perpetration linked to internalized homophobia. This study confirms findings in a growing body of research supporting the relationship between minority stress and increased prevalence of IPV among men who have sex with men, and points to the need to address structural factors in IPV prevention programs for male-male couples.

Various risk factors of intimate partner violence (IPV) have been found to vary by gender. South Korea has one of the highest prevalences of IPV in the world; however, little is known about potential risk factors of IPV and whether gender influences this relationship. Using data from the 2006 Korea Welfare Panel Study, 8,877 married participants (4,545 men and 4,332 women) aged ≥30 years were included. Reported IPV was categorized as verbal or physical IPV and the association between IPV and related factors was assessed by multivariate logistic regression analysis. Women were significantly more likely than men were to report IPV victimization (verbal 28.2% vs. 24.4%; physical 6.9% vs. 3.4%). Wor odds of physical perpetration than women satisfied with their family. Moreover, alcohol intake was significantly associated with IPV perpetration and victimization in both genders. Significant gender-specific differences were found among factors related to perpetrating violence and being a victim of violence among adults in heterosexual relationships in South Korea.

Alcohol use and impulsivity are two known risk factors for intimate partner violence (IPV). The current study examined the independent and interactive effects of problematic drinking and five facets of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) on perpetration of physical IPV within a dyadic framework. Participants were 289 heavy drinking heterosexual couples (total N = 578) with a recent history of psychological and/or physical IPV recruited from two metropolitan U.S. cities. Parallel multilevel Actor Partner Interdependence Models were utilized and demonstrated Actor problematic drinking, negative urgency, and lack of perseverance were associated with physical IPV. Findings also revealed associations between Partner problematic drinking and physical IPV as well as significant Partner Problematic Drinking x Actor Impulsivity (Negative Urgency and Positive Urgency) interaction effects on physical IPV. Findings highlight the importance of examining IPV within a dyadic framework and are interpreted using the I3 meta-theoretical model. PMID:26828640

Background: The experience of intimate partner violence (IPV) has been shown to decrease condom negotiation efficacy among women; however, studies of this association among gay and bisexual men (GBM) are lacking. Methods: A venue-recruited sample of 745 GBM was recruited in Atlanta, GA, USA in 2012-13. Participants self-completed a survey including questions on recent (previous 12 month) experience and perpetration of IPV using the IPV-GBM Scale. Multivariate regression analysis examined the association between reporting low condom negotiation efficacy with the respondent's most recent sex partner (19.2% of respondents) and recent experience of IPV with the same or another partner. Results: Nearly half the sample (49.1%) reported recent receipt of IPV, although prevalence varied considerably across the forms of IPV. GBM who reported recent IPV experience were significantly less likely to report having felt able to negotiate condom use. Conclusions: These findings suggest that IPV may be a significant risk factor for HIV acquisition and transmission among GBM.

Intimate partner violence (IPV) has important impacts on the health of women in society. Our aim was to estimate the health and economic benefits of reducing the prevalence of IPV in the 2008 Australian female adult population. Simulation models were developed to show the effect of a 5 percentage point absolute feasible reduction target in the prevalence of IPV from current Australian levels (27%). IPV is not measured in national surveys. Levels of psychological distress were used as a proxy for exposure to IPV since psychological conditions represent three-quarters of the disease burden from IPV. Lifetime cohort health benefits for females were estimated as fewer incident cases of violence-related disease and injury; deaths; and Disability Adjusted Life Years (DALYs). Opportunity cost savings were estimated for the health sector, paid and unpaid production and leisure from reduced incidence of IPV-related disease and deaths. Workforce production gains were estimated by comparing surveyed participation and absenteeism rates of females with moderate psychological distress (lifetime IPV exposure) against high or very high distress (current IPV exposure), and valued using the friction cost approach (FCA). The impact of improved health status on unpaid household production and leisure time were modelled from time use survey data. Potential costs associated with interventions to reduce IPV were not considered. Multivariable uncertainty analyses and univariable sensitivity analyses were undertaken. A 5 percentage point absolute reduction in the lifetime prevalence of IPV in the 2008 Australian female population was estimated to produce 6000 fewer incident cases of disease/injury, 74 fewer deaths, 5000 fewer DALYs lost and provide gains of 926,000 working days, 371,000 days of home-based production and 428,000 leisure days. Overall, AUD371 million in opportunity cost savings could be achievable. The greatest economic savings would be home-based production (AUD147 million), followed by leisure time (AUD98 million), workforce production (AUD94 million) and reduced health sector costs (AUD38 million). This study contributes new knowledge about the economic impact of IPV in females. The findings provide evidence of large potential opportunity cost savings from reducing the prevalence of IPV and reinforce the need to reduce IPV in Australia, and elsewhere.

Background: Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (dTpa-IPV; GSK Biologicals Boostrix™-Polio; 3-component pertussis) vs. full-strength DTPa-IPV vaccine (sanofi-pasteur—MSD Tetravac™; 2-component pertussis) was evaluated in pre-school Italian children.   Methods: Healthy children aged 5–6 y primed in a routine vaccination setting with three doses of DTPa-based vaccines were enrolled and randomized (1:1) in this phase IIIb, booster study to receive a single dose of dTpa-IPV or DTPa-IPV; the MMRV vaccine was co-administered. Antibody concentrations/titers against diphtheria, tetanus, pertussis and poliovirus 1–3 were measured before and one month post-booster. Reactogenicity and safety was assessed. Results: 305 subjects were enrolled of whom 303 (dTpa-IPV = 151; DTPa-IPV = 152) received booster vaccination. One month post-booster, all subjects were seroprotected/seropositive for anti-diphtheria, anti-tetanus, anti-PT, anti-FHA and anti-poliovirus 1–3; 99.3% of dTpa-IPV and 60.4% of DTPa-IPV subjects were seropositive for anti-PRN; 98–100% of subjects were seropositive against MMRV antigens post-booster. Pain at the injection site (dTpa-IPV: 63.6%; DTPa-IPV: 63.2%) and fatigue (dTpa-IPV: 26.5%; DTPa-IPV: 23.7%) were the most commonly reported solicited local and general symptoms, during the 4-d follow-up period. No SAEs or fatalities were reported. Conclusions: The reduced-antigen-content dTpa-IPV vaccine was non-inferior to full-strength DTPa-IPV vaccine with respect to immunogenicity. The vaccine was well-tolerated and can be confidently used as a booster dose in pre-school children. PMID:22327497

Evidence of increased STI/HIV-related risk behavior among male perpetrators of intimate partner violence in Guatemala: results from a national survey.

Intimate partner violence (IPV) is a significant public health problem with a demonstrated link to increased sexually transmitted infection (STI)/HIV-related risk and vulnerability. While IPV is an important issue in Central America, the link to STI/HIV risk has not been explored in this region. In this study, the relationship between emotional and physical/sexual IPV and the STI/HIV-related risk behaviors of sex worker patronage and infidelity is assessed among male IPV perpetrators using data from a national survey conducted in 2009 in Guatemala (n = 4773 married/partnered men). Bivariate associations between background characteristics and emotional and physical IPV perpetration were explored. Logistic regression models were run to test associations between IPV for each sexual risk behavior. Perpetration of emotional and physical/sexual IPV was more common among married/partnered men who were older than 24, had more education, lived in urban areas, or were in common law versus married unions. Reports of past-year emotional IPV perpetration increased as wealth quintile increased. After adjusting for demographics and other characteristics, physical/sexual IPV perpetration was associated with past-year infidelity (AOR 1.9, 95% CI: 1.1-3.6). Lifetime emotional IPV (AOR 1.4, 95% CI: 1.1-1.7) and physical/sexual IPV 1.6 (95% CI 1.2-2.0) were positively associated with a history of sex worker patronage. Endorsement of traditional gender role norms showed a marginally positive association with past-year infidelity in the adjusted model (AOR 1.3, 95% CI 1.0-1.8). The study findings from Guatemala reinforce the growing evidence globally that male IPV perpetrators are more likely to engage in risky sexual behavior, including sex worker patronage and main partner infidelity. The concurrency of violence and increased STI/HIV risk may compound the health risks for female victims of IPV who also face injury and psychological trauma. Integration of prevention and screening of IPV and STI/HIV prevention services should be adopted in Guatemala and other similar contexts.

Despite growing attention to intimate partner violence (IPV) globally, systematic evaluation of evidence for IPV prevention remains limited. This particularly is true in relation to low- and middle-income countries (LMIC), where researchers often organize evidence by current interventions strategies rather than comprehensive models of IPV. Applying the concept of structural interventions to IPV, we systematically reviewed the quantitative impact of such interventions for prevention of male-to-female IPV in LMIC in order to (a) highlight current opportunities for IPV research and programming and (b) demonstrate how structural interventions may provide an organizing framework through which to build an evidence base for IPV prevention. We identified articles by systematically searching PubMed and Web of Science, reviewing references of selected studies, and contacting 23 experts. Inclusion criteria included original research, written in English, published between January 2000 and May 2015 in the peer-reviewed literature. Studies evaluated the quantitative impact of structural interventions for the prevention of male-to-female IPV in LMIC through (a) IPV incidence or prevalence or (b) secondary outcomes theoretically linked to IPV by study authors. After initial screening, we evaluated full text articles for inclusion and extracted data on study characteristics, outcomes, and risk of bias, using forms developed for the review. Twenty articles (16 studies) from nine countries met inclusion criteria, representing 13 randomized control trials and seven additional studies, all of which reported results from economic, social, or combined economic and social interventions. Standardized at p < 0.05 or 95 % confidence intervals not including unity, 13 studies demonstrated statistically significant effects for at least one primary or secondary outcome, including decreased IPV and controlling behaviors; improved economic wellbeing; enhanced relationship quality, empowerment, or social capital; reduced acceptability of IPV; new help seeking behaviors; and more equitable gender norms. Risk of bias, however, varied in meaningful ways. Our findings support the potential effectiveness of structural interventions for IPV prevention. Structural interventions, as an organizing framework, may advance IPV prevention by consolidating available evidence; highlighting opportunities to assess a broader range of interventions, including politico-legal and physical approaches; and emphasizing opportunities to improve evaluation of such interventions.

2013-08-01

Despite the evidence that young and minority women may be particularly vulnerable to intimate partner violence (IPV), there is little research on the IPV experiences of minority undergraduate women. This study addresses this gap by estimating the prevalence of IPV and examining factors associated with experiencing IPV among undergraduate women attending Historically Black Colleges or Universities (HBCUs). Findings suggest alarmingly high victimization rates; however, factors associated with IPV among HBCU women are similar to those found in prior research with women in the general population. The results also suggest that some risk factors are differentially associated with experiencing specific types of IPV.

Trajectory of intimate partner violence and healthcare seeking over the life course: study of Japanese women in the Tokyo metropolitan area, Japan.

To describe the trajectory of, and examine factors affecting, intimate partner violence (IPV) and IPV-specific healthcare seeking among Japanese women over the life course. Life course study. One hundred and one women, aged 24-80 years, who had a lifetime history of IPV were interviewed in the Tokyo metropolitan area, Japan in 2005 and 2006. Life course data were collected according to the life history calendar method. Hierarchical linear modelling was used to examine IPV-specific healthcare seeking over the life course. Injury, formal or informal help seeking, public assistance, worse self-rated health status and smoking significantly increased the likelihood of IPV-specific healthcare seeking over the life course. There are significant cohort effects on healthcare seeking. The results suggest that women who experience IPV may seek healthcare services not only immediately after the first occurrence of IPV, but also later in life. IPV is not always associated with immediate healthcare seeking. In particular, sexual IPV is not significantly associated with healthcare seeking. Pursuing formal and informal help is associated with healthcare seeking. Copyright © 2013 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

The World Health Organization has recommended that a Sabin inactivated polio vaccine (IPV) should gradually and synchronously replace oral polio vaccines for routine immunizations because its benefits in eliminating vaccine-associated paralytic poliomyelitis have been reported in different phases of clinical trials. It is also considered important to explore new tetravalent diphtheria, tetanus, and acellular pertussis-Sabin IPV (DTaP-sIPV) candidate vaccines for possible use in developing countries. In this study, the immunogenicity of a combined tetravalent DTaP-sIPV candidate vaccine was investigated in primates by evaluating the neutralizing antibody responses it induced. The dynamic profiles of the antibody responses to each of the separate antigenic components and serotypes of Sabin IPV were determined and their corresponding geometric mean titers were similar to those generated by the tetravalent diphtheria, tetanus, and acellular pertussis-conventional IPV (DTaP-cIPV), the tetravalent diphtheria, tetanus, and acellular pertussis (DTaP), and Sabin IPV vaccines in the control groups. This implies that protective immunogenic effects are conferred by this combined tetravalent formulation. Copyright © 2013 Elsevier Ltd. All rights reserved.

Psychological intimate partner violence and sexual risk behavior: examining the role of distinct posttraumatic stress disorder symptoms in the partner violence-sexual risk link.

Research has examined how physical and sexual intimate partner violence (IPV) victimization increases sexual risk behavior, yet research is lacking on 1) the effect of psychological IPV on sexual risk behavior and 2) factors through which psychological IPV may be linked to sexual risk behavior. The current study examined the relationship between psychological IPV and sexual risk behavior controlling for other forms of IPV (i.e., physical and sexual) in a sample of 186 human immunodeficiency virus (HIV)-negative community women currently experiencing IPV. Further, this study examined the potential mediating effects of four posttraumatic stress disorder (PTSD) symptom severity clusters (i.e., re-experiencing, avoidance, numbing, and hyperarousal) on this relationship. Results revealed that greater severity of psychological IPV was uniquely and directly related to greater sexual risk behavior. Additionally, of the four PTSD symptom severity clusters, only avoidance symptom severity mediated the relationship between psychological IPV and sexual risk behavior. Implications for addressing psychological IPV and PTSD to improve women's sexual health outcomes are discussed. Copyright © 2015 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Intimate partner violence (IPV) against women is a global public health concern. While community-level gender norms and attitudes to IPV are recognised drivers of IPV risk, there is little evidence on how interventions might tackle these drivers to prevent IPV at the community-level. This secondary analysis of data from the SASA! study explores the pathways through which SASA!, a community mobilisation intervention to prevent violence against women, achieved community-wide reductions in physical IPV. From 2007 to 2012 a cluster randomised controlled trial (CRT) was conducted in eight communities in Kampala, Uganda. Cross-sectional surveys of a random sample of community members, aged 18-49, were undertaken at baseline (n = 1583) and 4 years post intervention implementation (n = 2532). We used cluster-level intention to treat analysis to estimate SASA!'s community-level impact on women's past year experience of physical IPV and men's past year perpetration of IPV. The mediating roles of community-, relationship- and individual-level factors in intervention effect on past year physical IPV experience (women)/perpetration (men) were explored using modified Poisson regression models. SASA! was associated with reductions in women's past year experience of physical IPV (0.48, 95 % CI 0.16-1.39), as well as men's perpetration of IPV (0.39, 95 % CI 0.20-0.73). Community-level normative attitudes were the most important mediators of intervention impact on physical IPV risk, with norms around the acceptability of IPV explaining 70 % of the intervention effect on women's experience of IPV and 95 % of the effect on men's perpetration. The strongest relationship-level mediators were men's reduced suspicion of partner infidelity (explaining 22 % of effect on men's perpetration), and improved communication around sex (explaining 16 % of effect on women's experience). Reduced acceptability of IPV among men was the most important individual-level mediator (explaining 42 % of effect on men's perpetration). These results highlight the important role of community-level norm-change in achieving community-wide reductions in IPV risk. They lend strong support for the more widespread adoption of community-level approaches to preventing violence. ClinicalTrials.gov, NCT00790959 . Registered 13th November 2008.

Development of inactivated poliovirus vaccine from Sabin strains: A progress report.

PubMed

Okayasu, Hiromasa; Sein, Carolyn; Hamidi, Ahd; Bakker, Wilfried A M; Sutter, Roland W

2016-11-01

The Global Polio Eradication Initiative (GPEI) has seen significant progress since it began in 1988, largely due to the worldwide use of oral poliovirus vaccine (OPV). In order to achieve polio eradication the global cessation of OPV is necessary because OPV contains live attenuated poliovirus, which in rare circumstances could re-gain wild poliovirus (WPV) characteristics with potential to establish transmission. The GPEI endgame strategy for the period 2013-2018 recommends the globally synchronised sequential cessation of the Sabin strains contained in the OPV, starting with type 2 Sabin. The withdrawal of Sabin type 2 took place in April 2016, with the introduction of at least one dose of inactivated poliovirus vaccine (IPV) as a risk mitigation strategy. The introduction of IPV into 126 countries since 2013 has required a rapid scale-up of IPV production by the two manufacturers supplying the global public sector market. This scale-up has been fraught with challenges, resulting in reductions of 40-50% of initial supply commitments. Consequently, 22 countries will not be supplied until 2018, and another 23 countries will experience serious stock-outs. In the last decade repeated calls-for-action were made to the global community to invigorate their vision and investment in developing "new poliovirus vaccines" including the development of IPV from less-virulent strains, such as Sabin-IPV (S-IPV). The conventional Salk-IPV production is limited to high-income industrialized-country manufacturers due to the containment requirements (i.e., high sanitation, low force-of-poliovirus-infection, and high population immunity). The use of Sabin strains in the production of S-IPV carries a lower biosafety risk, and was determined to be suitable for production in developing countries, expanding the manufacturing base and making IPV more affordable and accessible in the long term. Significant progress in the S-IPV has been made since 2006. S-IPV is now licensed as S-IPV in Japan and as standalone S-IPV in China, demonstrating the feasibility of this vaccine. In addition, production process improvements can further reduce the cost of production. The latter are critical to the economic success of this vaccine in the global market. We summarize the progress made to date in S-IPV technology, the scientific data and economic evidence in support of S-IPV development.

Enhanced maternal and child health nurse care for women experiencing intimate partner/family violence: protocol for MOVE, a cluster randomised trial of screening and referral in primary health care

PubMed Central

2012-01-01

Background Intimate partner violence (IPV) can result in significant harm to women and families and is especially prevalent when women are pregnant or recent mothers. Maternal and child health nurses (MCHN) in Victoria, Australia are community-based nurse/midwives who see over 95% of all mothers with newborns. MCHN are in an ideal position to identify and support women experiencing IPV, or refer them to specialist family violence services. Evidence for IPV screening in primary health care is inconclusive to date. The Victorian government recently required nurses to screen all mothers when babies are four weeks old, offering an opportunity to examine the effectiveness of MCHN IPV screening practices. This protocol describes the development and design of MOVE, a study to examine IPV screening effectiveness and the sustainability of screening practice. Methods/design MOVE is a cluster randomised trial of a good practice model of MCHN IPV screening involving eight maternal and child health nurse teams in Melbourne, Victoria. Normalisation Process Theory (NPT) was incorporated into the design, implementation and evaluation of the MOVE trial to enhance and evaluate sustainability. Using NPT, the development stage combined participatory action research with intervention nurse teams and a systematic review of nurse IPV studies to develop an intervention model incorporating consensus guidelines, clinical pathway and strategies for individual nurses, their teams and family violence services. Following twelve months’ implementation, primary outcomes assessed include IPV inquiry, IPV disclosure by women and referral using data from MCHN routine data collection and a survey to all women giving birth in the previous eight months. IPV will be measured using the Composite Abuse Scale. Process and impact evaluation data (online surveys and key stakeholders interviews) will highlight NPT concepts to enhance sustainability of IPV identification and referral. Data will be collected again in two years. Discussion MOVE will be the first randomised trial to determine IPV screening effectiveness in a community based nurse setting and the first to examine sustainability of an IPV screening intervention. It will further inform the debate about the effectiveness of IPV screening and describe IPV prevalence in a community based post-partum and early infant population.

In Rwanda, women who self-reported in household surveys ever experiencing intimate partner violence (IPV) increased from 34 % in 2005 to 56 % in 2010. This coincided with a new constitution and majority-female elected parliament in 2003, and 2008 legislation protecting against gender-based violence. The increase in self-reported IPV may reflect improved social power for women, and/or disruptions to traditional gender roles that increased actual IPV. This is a cross-sectional study of IPV in 4338 couples interviewed in the 2005 and 2010 Rwanda Demographic and Health Surveys (RDHSs). Factors associated with physical or sexual IPV in the last 12 months were modeled using manual backward stepwise logistic regression. Analyses were conducted in Stata v13 adjusting for complex survey design. Risk factors for IPV in 2005 (p < 0.05) were: experiencing emotional IPV (OR = 18.1), beating husband/partner unprovoked (OR = 12.3), witnessing IPV against mother (OR = 1.82), husband/partner consumes alcohol often (OR = 3.13), and polygynous marriage (OR = 1.51), whereas having a husband/partner with secondary education (OR = 0.43) was protective. Factors associated with increased IPV in 2010 (p < 0.05) were husband/partner (OR = 1.30) or woman (OR = 1.36) believes IPV is justified, husband/partner has sex with non-marital partners (OR = 2.52), bottom wealth quintile (OR = 1.25), polygynous marriage (OR = 2.29), having a son (OR = 2.05) or only daughters (OR = 2.58) versus no children, and having a husband/partner employed with in-kind versus cash compensation (OR = 1.58). In 2010, woman being involved with her own health (OR = 0.79) or earnings (OR = 0.57) decision-making was protective against IPV. Several variables were not available in the 2010 RDHS. Our results may provide evidence of both increased self-reporting of IPV and social power disruption. Rwanda's Isange One Stop Center project, with medical, legal, and psychosocial services for domestic violence victims, is currently scaling to all 44 district hospitals, and police station gender desks reduce barriers to legal reporting of IPV. Additional support to Abunzi mediators to hear IPV cases in communities, and involvement of men in grassroots efforts to redefine masculinity in Rwanda are suggested. Additional research is needed to understand why self-reported IPV has increased in Rwanda, and to evaluate effectiveness of IPV interventions.

Intimate partner violence and initiation of smoking and drinking: A population-based study of women in Yokohama, Japan.

Intimate Partner Violence (IPV) is prevalent in the lives of women across the globe and has been found to be associated with substance use among women. As part of the World Health Organization's (WHO) cross-national research effort, this study examined the relationship between the experience of IPV and use of alcohol and tobacco among a probability sample of women aged 18-49 in Yokohama, Japan. Using retrospective data for 2000-2001, we employed methods of survival analysis that allowed an examination of the probability of initiating smoking and drinking subsequent to the experience of IPV. Experiencing IPV was associated with current smoking as well as initiation of smoking and current patterns of drinking. Women who had experienced IPV were more likely to be smoking at the time of the interview and tended to initiate smoking at earlier ages compared to those who had not experienced IPV. At any time point, the risk of starting to smoke was more than twice as high for women who had previously experienced IPV than for women who had not. In addition, women who had experienced IPV were more likely to drink heavily. The present study's findings clearly point to the need to enhance coordination between IPV prevention and substance abuse programs in order to improve the safety and wellbeing of women who have experienced IPV.

African American women are at heightened risk for intimate partner violence (IPV) and its negative consequences, including health-compromising behaviors. Deliberate self-harm (DSH) is one clinically-relevant behavior that has been understudied among African American women generally and those with exposure to IPV in particular. To date, no studies have examined factors that may account for the relationship between IPV and DSH. Therefore, the goal of the present study was to examine the intercorrelations among IPV (physical, psychological, and sexual), PTSD, and DSH history and versatility, and the potentially mediating role of PTSD symptoms in the IPV-DSH relation. Participants were 197 African American community women currently experiencing IPV. Sixty participants (31%) reported a history of DSH. Among participants who reported DSH, there was an average endorsement of 2.3 unique forms of deliberate self-harm (i.e., DSH versatility). Significant positive associations were detected among physical IPV severity, psychological IPV severity, PTSD symptom severity, and DSH history and versatility. PTSD symptom severity mediated the relationships between physical and psychological IPV severity and DSH history and versatility. Results highlight the relevance of PTSD symptoms to DSH and suggest that treatments targeting PTSD symptoms may be useful in reducing DSH among IPV-exposed African American women. Copyright © 2014.

The high rate of intimate partner violence (IPV) victimisation found among substance-using women receiving community supervision underscores the need for effective IPV victimisation screening, brief intervention and referral to treatment services (SBIRT) for this population. This randomised controlled trial (RCT) aims to assess the feasibility, safety and efficacy of a single-session computerised self-paced IPV SBIRT (Computerised WINGS) in identifying IPV victimisation among women under community supervision and increasing access to IPV services, compared to the same IPV SBIRT service delivered by a case manager (Case Manager WINGS). This RCT was conducted with 191 substance-using women in probation and community court sites in New York City. No significant differences were found between Computerised and Case Manager WINGS arms on any outcomes. Both arms reported identical high rates of any physical, sexual or psychological IPV victimisation in the past year (77% for both arms) during the intervention. Both arms experienced significant increases from baseline to the 3-month follow-up in receipt of IPV services, social support, IPV self-efficacy and abstinence from drug use. Findings suggest that both modalities of WINGS show promise in identifying and addressing IPV victimisation among substance-using women receiving community supervision.

To estimate (i) lifetime prevalence of physical and sexual intimate partner violence (IPV) and (ii) associations of development of complications around delivery and IPV. We used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 2001 currently married women having a child younger than five years. Exposure was determined from maternal reports of physical and sexual IPV. Experience of complications around delivery was the main outcome variable of interest. More than half (53%) of the women had experienced IPV. IPV of any type (adjusted odds ratio [AOR]: 1.86; 95% confidence interval [CI]: 1.35-2.56) was associated with development of complications, as was physical IPV only (AOR: 1.63; 95% CI: 1.14-2.33), sexual IPV only (AOR: 2.0; 95% CI: 1.01-3.99), and both types of IPV (AOR: 2.43; 95% CI: 1.55-3.79). There was a dose-response relationship between the number of varieties of physical IPV suffered and complications developing. Experience of IPV is an important risk marker for the development of complications around delivery. Our findings underscore the calls for protecting women from all forms of physical and sexual violence from their husbands as part of the interventions to reduce the risk of complications supervening around delivery. They should be considered a public health research priority.

Intimate partner violence and physical health consequences: policy and practice implications.

PubMed

Plichta, Stacey B

2004-11-01

Extensive research indicates that intimate partner violence (IPV) poses a significant risk to the physical health of women. IPV is associated with increased mortality, injury and disability, worse general health, chronic pain, substance abuse, reproductive disorders, and poorer pregnancy outcomes. IPV is also associated with an overuse of health services and unmet need for services, as well as strained relationships with providers. The body of IPV research has several critical gaps. There are almost no longitudinal studies of IPV and health. Most studies are clustered into a few specialties, with almost no research in the areas of allied health, dentistry, or management. A common definition of IPV is still not used. Finally, with some notable exceptions, there has been little success in moving the health care system to routinely screen women for IPV.

This paper describes how substance use features in the accounts of intimate partner violence (IPV) perpetrators in treatment in England and Brazil. The aim of the research was to better understand cross cultural constructions of IPV perpetration amongst men in treatment for substance use. Semi-structured interviews were conducted with 40 men in community substance use treatment in Sao Paolo, Brazil and London and the South East of England who had reported IPV perpetration in a questionnaire survey. A thematic, narrative analysis was carried out of men's explanations for IPV perpetration. Three types of narratives were distinguished: (i) disputes, centred on substance use, that escalate to IPV perpetration; (ii) IPV perpetration that is explained by uncharacteristic loss of control, as a result of intoxication; and (iii) IPV perpetration provoked by a perceived betrayal, in which substance use is incidental. In all types of accounts hegemonic principles of male and female roles and behaviour provided a context for and make IPV perpetration explicable. Substance use and IPV are culturally constructed and contextually defined. Understanding the meaning-making of substance using IPV perpetrators has implications for the treatment of both substance abuse and IPV.

Abstract: Background: Many organizations have conducted Intimate Partner Violence (IPV) informational campaigns, but the extent to which such cost-effective, simple changes to the clinic environment can improve patient perceptions about IPV is largely unknown. Our primary objective was to determine how an IPV informational program affects patients’ perceptions about discussing IPV in a fracture clinic setting. Methods: We conducted a pre-post intervention study to evaluate the impacts of an IPV informational program on patients’ perceptions and willingness to discuss IPV in an orthopaedic fracture clinic setting. During the intervention phase, there were posters and brochures in each bed area and several places in the waiting area, and the surgeons received a button to wear on their lab coat stating their openness to discuss IPV and a set of instructions on how to ask patients about IPV and refer them to resources. Results: A total of 160 patients (80 pre-intervention and 80 post-intervention) have participated in this study. Overall perception of the clinic as an open place in which to discuss IPV did not change as a result of the informational program compared to the control setting. However, more patients exposed to posters and information about IPV believed the clinic staff possessed resources to help IPV victims compared to the control group; however, this difference did not reach statistical significance (62% vs. 53%, respectively, p=0.29). Conclusions: Passive interventions may serve an adjunctive role in facilitating active interventions in a clinic environment, but should not be considered in isolation as an effective approach.

While there is a growing body of research on intimate partner violence (IPV) experienced by the housed youth population, a limited amount is known about IPV experienced by homeless youth. To our knowledge, no previous studies have examined how homeless youths’ experience of IPV is related to their social network, even though the social networks of homeless youth have been shown to be significant indicators of health and mental health. The purpose of this study is to understand the relationship between IPV, gender, and social networks among a sample of 386 homeless youth in Los Angeles, California. Results revealed that one fifth of the sample experienced IPV in the past year. Stratified regression models revealed that IPV was not significantly related to any measure of male social networks; however, females who experienced IPV had more male friends (β = 2.03, SE = 0.89, p < .05) than females who did not experience IPV. Female homeless youth who witnessed family violence during childhood had more male friends (β = 2.75, SE = 1.08, p < .05), but those who experienced sexual abuse during childhood had fewer male friends (β = −2.04, SE = 0.93, p < .05). Although there was no significant difference in the rate of IPV victimization across genders, the context of this abuse appears to be drastically different. The results suggest that females with more male friendships are at greater risk for exposure to IPV. To date, there are few effective youth-targeted IPV prevention programs and none have been shown to be effective with homeless youth. These results provide insight into future program development.

Is gender important? Victimisation and perpetration of intimate partner violence in mainland China.

PubMed

Breckenridge, Jan; Yang, Ting; Poon, Abner Weng Cheong

2018-04-14

Establishing the prevalence of intimate partner violence (IPV) has been recommended by International Conventions and Declarations for some time beginning with the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW Articles 12 and 19) in 1979. One important recommendation of such international protocols is the implementation of national population prevalence surveys to establishing IPV as a serious social issue globally, which is intended to provide data for planning effective responses within signatory countries. However, not all countries have undertaken national prevalence surveys meaning that there are gaps in our understanding of who are the perpetrators and victims of IPV in different cultural contexts. This article presents the results of a scoping review of literature examining gender differences in prevalence rates of victimisation and perpetration of IPV in mainland China (hereon China). There has been little written about the prevalence of IPV in China generally, and this scoping process located only nine peer-reviewed articles written in both English- and Chinese-language journals focusing on both gender and IPV published between 1997 and 2016. Results of this scoping review demonstrate that while both women and men perpetrate IPV in China, the prevalence rates of different types of IPV reflect gender differences in both perpetration and victimisation, suggesting that IPV is not a unitary phenomenon. The paper concludes by discussing the implications of the findings including the importance of increasing awareness of IPV in China more generally and developing gender-specific interventions to directly address different types of IPV. Directions for future research are also canvassed. © 2018 John Wiley & Sons Ltd.

Objectives were to assess associations between intimate partner violence (IPV), violence during armed conflict (i.e. crisis violence), and probable post-traumatic stress disorder (PTSD). Using a sample of 950 women in rural Côte d'Ivoire, logistic generalized estimating equations assessed associations between IPV and crisis violence exposures with past-week probable PTSD. Over one in 5 (23.4%) women reported past-year IPV, and over one in 4 women (26.5%) reported experiencing IPV prior to the past year (i.e. remote IPV). Crisis violence was experienced by 72.6% of women. In adjusted models including demographics, crisis violence (overall and specific forms), and IPV (remote and past-year), women who reported past-year IPV had 3.1 times the odds of reporting probable past-week PTSD (95%CI: 1.8-5.3) and those who reported remote IPV had 1.6 times the odds (95%CI: 0.9-2.7). Violent exposures during the crisis were not significantly associated with probable PTSD (any crisis violence: aOR: 1.04 (0.7-1.5); displacement: aOR: 0.9 (95%CI: 0.5-1.7); family victimization during crisis: aOR: 1.1 (95%CI: 0.8-1.7); personal victimization during crisis: aOR: 1.7 (95%CI: 0.7-3.7)). Past-year IPV was more strongly associated with past-week probable PTSD than remote IPV and violence directly related to the crisis. IPV must be considered within humanitarian mental health and psychosocial programming.

Objective Intimate partner violence (IPV) is the most prevalent form of gender-based violence worldwide. IPV either before or during pregnancy has been documented as a risk factor for the health of the mother and her unborn child. The aim of this study was to examine the relationship between maternal experience of IPV and low birth weight (LBW). Study design A hospital-based survey was conducted among women in the postnatal wards of a large public hospital at Rajshahi, Bangladesh. Data on socio-economic characteristics, reproductive health characteristics, intimate partner violence, and antenatal, delivery and newborn care were collected from 400 women between July 2015 and April 2016. Results Results of this study indicated that 43% of women reported experiencing any physical IPV in their lifetime, 35.5% of them experienced sexual IPV, and 32.5% experienced both physical and sexual IPV. Approximately one in every three (29.2%) infants was born with LBW. Physical IPV was associated with an increased risk of having a child with low birth weight (adjusted odds ratio [AOR]: 3.01, 95% CI: 2.35–5.81). The risk of infants born with LBW increased with women’s lifetime experience of sexual IPV (AOR: 1.98; 95% CI: 1.23–4.15) and both physical and sexual IPV (AOR: 4.05; 95% CI: 2.79–7.33). Conclusion Maternal lifetime experience of IPV is positively associated with LBW children. Preventing women from the experience of IPV may help improve neonatal and child mortality in Bangladesh.

Background Intimate partner violence (IPV) has been known to adversely affect the mental health of victims. Research has tended to focus on the mental health impact of physical violence rather than considering other forms of violence. Objective To systematically review the literature in order to identify the impact of all types of IPV victimisation on various mental health outcomes. Method A systematic review of 11 electronic databases (2004–2014) was conducted. Fifty eight papers were identified and later described and reviewed in relation to the main objective. Results Main findings suggest that IPV can have increasing adverse effects on the mental health of victims in comparison with those who have never experienced IPV or those experiencing other traumatic events. The most significant outcomes were associations between IPV experiences with depression, posttraumatic stress disorder, and anxiety. Findings confirm previous observations that the severity and extent of IPV exposure can increase mental health symptoms. The effect of psychological violence on mental health is more prominent than originally thought. Individual differences such as gender and childhood experience of violence also increase IPV risk and affect mental health outcomes in diverse ways. Conclusions Psychological violence should be considered as a more serious form of IPV which can affect the mental health of victims. Experiencing more than one form of IPV can increase severity of outcomes. Researchers should look at IPV as a multi-dimensional experience. A uniformed definition and measure of IPV could help advance knowledge and understanding of this disparaging global issue. PMID:25279103

This study describes the prevalence and correlates of past-year intimate partner violence (IPV) among displaced women. We used bivariate and multivariate analyses to assess the relationships between IPV and select variables of interest. Multivariate logistic regression modeling revealed that women who had experienced outsider violence were 11 times as likely (adjusted odds ratio [AOR] = 11.21; confidence interval, CI [5.25, 23.96]) to have reported IPV than women who had not experienced outsider violence. IPV in conflict-affected settings is a major public health concern that requires effective interventions; our results suggest that women who had experienced outsider violence are at greater risk of IPV. © The Author(s) 2015.

INTIMATE PARTNER VIOLENCE AND DEPRESSIVE SYMPTOMS DURING ADOLESCENCE AND YOUNG ADULTHOOD

Using longitudinal data from the Toledo Adolescent Relationships Study (TARS), we examine the relationship between intimate partner violence (IPV) and depressive symptoms during adolescence and young adulthood (N = 1, 273) while controlling for time-stable and time-varying correlates. Results show temporal changes in depressive symptoms, such that increases in depressive symptoms correspond to IPV exposure. While prior work has theorized that certain populations may be at increased psychological vulnerability from IPV, results indicate that both perpetration and victimization are associated with increases in depressive symptoms for both men and women and irrespective of whether IPV exposure occurred in adolescence or young adulthood. Cumulative exposure to IPV does not appear to increase depressive symptoms beyond the effect observed for the most recent IPV exposure, but physical maltreatment by a parent does appear to diminish the effect of IPV perpetration on depressive symptoms for a small subset of the sample.

Intimate partner violence (IPV) is a major public health problem in the United States. Negative outcomes of IPV affect women's attainment and maintenance of employment. The purpose of this study was to develop a theoretical framework that described and explained the process by which women who have experienced IPV attain and maintain employment. Grounded theory methodology was used to analyze interviews of 34 women who had experienced IPV. Analysis suggested that women who had experienced IPV could attain employment; however, they had difficulty maintaining employment. Entanglement of work and IPV was experienced by all 34 participants because of the perpetrator controlling their appearance, sabotaging their work, interfering with their work, or controlling their finances. Some women described ways in which they disentangled work from IPV through a dynamic unraveling process, with periods of re-entanglement, resulting in job security and satisfaction. © 2016 The Author(s).

Japanese women's perceptions of intimate partner violence (IPV).

Intimate partner violence (IPV) is a problem in Japan. The purpose is to describe IPV as perceived by a purposive sample of 11 Japanese adult females who were in a heterosexual marriage at the time of IPV. We used a cross-sectional, retroactive, qualitative description research design with individual, fact-to-face in depth interviews. At the time of the interview, the women had a mean age of 38 years and at the time of the IPV, a mean age of 28 years. Data were analyzed using the directed qualitative content analysis method. The results revealed that all women experienced physical and emotional abuse and 82% experienced sexual abuse. Communication between spouses was characterized as unilateral, with husbands initiating and dominating the conversation. The women identified the culture of the Japanese patriarchal system as directly influencing IPV. The implication is health professionals should actively advocate for effective legislation and policies to address IPV.

We aimed to examine the influence of witnessing father-to-mother violence on: 1) perpetration of intimate partner violence (IPV); and 2) endorsement of attitudes justifying wife beating in Bangladesh. This paper used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 3374 ever-married men. Exposure to IPV was determined by men's self-reports of witnessing inter-parental violence in childhood. We used adjusted binary logistic regression models to assess the influence of exposure on husbands' perpetration of IPV and their endorsement of attitudes justifying wife beating. Nearly 60% of men reported violent behaviour towards an intimate partner and 35.7% endorsed attitudes justifying spousal abuse. Men who witnessed father-to-mother violence had higher odds of reporting any physical or sexual IPV (adjusted OR [AOR] = 3.26; 95% CI = 2.61, 4.06). Men who had witnessed father-to-mother violence were also 1.34 times (95% CI = 1.08, 1.65) more likely endorse attitudes justifying spousal abuse. Committing violence against an intimate partner is an all too frequent practice among men in Bangladesh. The study indicated that men who had witnessed father-to-mother violence were more likley to perpetrate IPV, suggesting an intergenerational transmission of violence. This transmission of violence may operate through the learning and modelling of attitudes favourable to spousal abuse. In support of this, witnnessing inter-parental violence was also associated with the endorsement of attitudes justifying spousal abuse. Our findings indicate the continued importance of efforts to identify and assist boys who have witnessed domestic violence and suggest such efforts should aim to change not just behaviours but also attitudes that facilitate such violence.

The relationship between level of childhood abuse (physical and emotional) and sexual risk behavior of sexually transmitted disease clinic patients in St. Petersburg, Russia was examined through path analyses. Mediating variables investigated were: Alcohol Use Disorder Identification Test (AUDIT), drinking motives (for social interaction, to enhance mood, to facilitate sexual encounters), intimate partner violence (IPV), anxiety, and depression symptoms. Results showed a significant indirect effect of childhood abuse on women's sexual risk behavior: higher level of childhood abuse was associated with a greater likelihood of IPV, motivations to drink, leading to higher AUDIT scores and correlated to higher likelihood of having multiple, new or casual sexual partner(s). No significant effect was identified in paths to condom use. Among men, childhood abuse had no significant effect on sexual risk behavior. Reduction in alcohol-related sexual risk behavior may be achieved by addressing the effects of childhood abuse among female participants.

Beyond passivity: Dependency as a risk factor for intimate partner violence.

Kane, Fallon A; Bornstein, Robert F

2016-02-01

Interpersonal dependency in male perpetrators of intimate partner violence (IPV) is an understudied phenomenon but one that has noteworthy clinical implications. The present investigation used meta-analytic techniques to quantify the dependency-IPV link in all extant studies examining this relationship (n of studies = 17). Studies were gathered via an extensive literature search using relevant dependency/IPV search terms in the PsychInfo, Medline and Google Scholar databases. Results revealed a small but statistically significant relationship between dependency and perpetration of IPV in men (r = 0.150, Combined Z = 4.25, p < 0.0001), with the magnitude of the dependency-IPV link becoming stronger (r = 0.365, Combined Z = 6.00, p < 0.0001) when studies using measures of dependent personality disorder symptoms were omitted. Other moderators of the dependency-IPV effect size included IPV measure, type of sample and perpetrator age. These findings illuminate the underlying dynamics and interpersonal processes involved in some instances of IPV and may aid in understanding how to identify and treat male perpetrators of domestic violence.

Childhood Sexual Abuse and Fear of Abandonment Moderate the Relation of Intimate Partner Violence to Severity of Dissociation.

PubMed

2018-01-01

Betrayal trauma theory proposes a relation between intimate partner violence (IPV) and dissociation, suggesting that dissociation among victims of IPV may function to restrict awareness of abuse in order to preserve attachments perceived as vital. We investigated two factors that may moderate the relation between IPV and dissociation-childhood sexual abuse (CSA) severity and fear of abandonment-among 348 women currently in a relationship. The relation between frequency of IPV (sexual and physical) and dissociation (amnesia and depersonalization) was moderated by CSA severity and fear of abandonment. Specifically, among women with clinically relevant fear of abandonment, the strength of the relation between IPV and dissociation became stronger as CSA severity increased. This study is the first to demonstrate the moderating roles of fear of abandonment and CSA history in the relation between IPV and dissociation among women. Findings suggest that it may be important to target fear of abandonment in interventions with IPV victims who have a CSA history. Results suggest that fear of abandonment warrants greater attention in research on IPV revictimization.

The Substance Abuse, Violence, and HIV/AIDS (SAVA) syndemic model describes how the confluence of the three epidemics of substance abuse, violence, and HIV risk work synergistically to create excess burden among populations. We sought to identify risk factors associated with recent intimate partner violence (IPV) victimization among heterosexual methamphetamine (meth)-using men (n = 108) and women (n = 122) enrolled in FASTLANE-II, an HIV behavioral intervention in San Diego, CA. Women and men reported high rates of physical-only (women: 20%; men: 18%) and sexual (women: 25%; men: 23%) IPV. Multinomial regression analysis revealed that individuals who reported lower social support and individuals who reported a greater likelihood of engaging in risky sexual behaviors while high on meth were more likely to report IPV versus no IPV. Women who reported a greater likelihood of engaging in risky sexual behaviors while high on meth were 1.58 times more likely to report physical-only IPV versus no IPV, while men who reported similar behaviors were 1.15 times more likely to report physical-only IPV versus no IPV. Our findings highlight the influence of interpersonal factors on IPV. This research supports further study on gender-specific risk/protective factors and the development of gender-specific interventions targeting the SAVA syndemic among meth users. PMID:27163712

Few programs exist to address Intimate Partner Violence (IPV) in Guinea. In 2014, Engender Health, in partnership with the local health authorities in Conakry, Guinea, piloted an integrated approach to IPV screening and counseling, within an existing family planning clinic. This article describes both the process of formulating and implementing this approach, as well as the results of an evaluation of the program. From January to June of 2014, Engender Health staff trained midwives at the Conakry International Planned Parenthood Federation family planning clinic staff in screening and counseling client for IPV. Program evaluators used project records, interview with program staff (n=3), midwives (n=3) and client exit interviews (n=53) to measure the outcomes of this pilot project. Regardless of their IPV status, clients appreciated having a venue in which to discuss IPV. Program staff also felt empowered by the additional training and support for IPV screening. The evaluation yielded valuable suggestions for improvement, including more time for staff training and mock client interview practice, additional skills in counseling, and stronger referral links for women who screen positive for IPV. Integrating IPV screening into family planning services is an important and feasible method for reaching vulnerable women with IPV services.

Intimate partner violence (IPV) is a public health problem that reaches across age, sex, and ethnicity. In this study, we examined risk factors for physical IPV perpetration among young adult males and females from four ethnic groups. Data were taken from Waves 1-3 of the National Longitudinal Study of Adolescent Health (Add Health). The sample included 10,141 Wave 3 respondents (ages ranged from 18-27 years old) who reported being in a current romantic relationship. Physical IPV perpetration was reported by 14.10% of White, 23.28% of Black, 18.82% of Latino, and 18.02% of Asian males. Physical IPV perpetration was reported by 19.01% of White, 24.80% of Black, 25.97% of Latina, and 19.21% of Asian females. Following an ecological framework, proximal risk factors at intrapersonal and interpersonal levels were included in the analyses. Despite finding fairly consistent percentage of physical IPV perpetration across sample groups, the risk factors for physical IPV perpetration were rather uncommon across sex and ethnicity. Only 1 factor--psychological IPV perpetration toward a romantic partner--was consistently associated with physical IPV perpetration across all groups. Our findings have implications for tailoring prevention and intervention efforts toward risk factors of physical IPV perpetration that are uniquely associated with biological sex and ethnicity.

In order to search the preparation process and optimazing dosage ratio of adsorbed diphtheria-tetanus-acellular pertussis and sabin inactivated poliovirus combined vaccine (DTaP-sIPV), the neutralizing antibody titers of IPV induced by different concentration of DTaP-sIPV were investigated on rats. Two batches of DTaP-sLPV were produced using different concentration of sIPV and the quality control was carried. Together with sabin-IPV and DTaP-wIPV ( boostrix-polio, GSK, Belgium) as control group, the DTaP-sIPV were administrated on three-dose schedule at 0, 1, 2 month on rats. Serum sample were collected 30 days after each dose and neutralizing antibody titers against three types poliovirus were determined using micro-neutralization test. Two batches of prepared DTaP-sIPV and control sLPV were according to the requirement of Chinese Pharmacopoeia (Volume III, 2005 edition) and showed good stability. The seropositivity rates were 100% for sabin inactivated poliovirus antigen in all groups. The GMTs (Geometric mean titers) of neutralizing antibodies against three types poliovirus increased. The prepared DTaP-sIPV was safe, stable and effective and could induced high level neutralizing antibody against poliovirus on rats.

[Inactivated poliovirus vaccines: an inevitable choice for eliminating poliomyelitis].

The inactivated poliovirus vaccine (IPV) is a very old tool in the fight against poliomyelitis. Though supplanted by oral poliovirus vaccine (OPV) in the 1960s and 1970s, the IPV has now become an inevitable choice because of the increasingly recognized risks associated with continuous use of OPVs. Following the pioneering work of Jonas Salk, who established key principles for the IPV, considerable experience has accumulated over the years. This work has led to modern Salk IPV-containing vaccines, based on the use of inactivated wildtype polioviruses, which have been deployed for routine use in many countries. Very good protection against paralysis is achieved with IPV through the presence of circulating antibodies able to neutralize virus infectivity toward motor neurons. In addition, with IPV, a variable degree of protection against mucosal infection (and therefore transmission) through mucosal antibodies and immune cells is achieved, depending on previous exposure of subjects to wildtype or vaccine polioviruses. The use of an IPV-followed-by-OPV sequential immunization schedule has the potential advantage of eliminating the vaccine-associated paralytic poliomyelitis (VAPP) risk, while limiting the risks of vaccine-derived poliovirus (VDPVs). Sabin strain-derived IPVs are new tools, only recently beginning to be deployed, and data are being generated to document their performance. IPVs will play an irreplaceable role in global eradication of polio.

Objective To compare in person versus computerized screening for intimate partner violence (IPV) in a hospital-based prenatal clinic and explore women’s assessment of the screening methods. Methods We compared patient IPV disclosures on a computerized questionnaire to audio-taped first obstetric visits with an obstetric care provider and performed semi-structured interviews with patient participants who reported experiencing IPV. Results Two-hundred and fifty patient participants and 52 provider participants were in the study. Ninety-one (36%) patients disclosed IPV either via computer or in person. Of those who disclosed IPV, 60 (66%) disclosed via both methods, but 31 (34%) disclosed IPV via only one of the two methods. Twenty-three women returned for interviews. They recommended using both types together. While computerized screening was felt to be non-judgmental and more anonymous, in person screening allowed for tailored questioning and more emotional connection with the provider. Conclusion Computerized screening allowed disclosure without fear of immediate judgment. In person screening allows more flexibility in wording of questions regarding IPV and opportunity for interpersonal rapport. Practice Implications Both computerized or self-completed screening and in person screening is recommended. Providers should address IPV using non-judgmental, descriptive language, include assessments for psychological IPV, and repeat screening in person, even if no patient disclosure occurs via computer.

Substance and mental health disorders convey significant health burdens and impair interpersonal relationships. We tested associations between comorbid substance and mental health disorders and different forms of intimate partner violence (IPV) experienced by young adults. Mothers (n = 6703) were recruited during pregnancy to the longitudinal Mater-University of Queensland Study of Pregnancy. Mother/offspring dyads were followed up from birth to 21 years. Offspring with complete psychiatric data at 21 years who reported having had an intimate partnership were included (n = 1781). Participants' experiences of psychological, physical and severe combined IPV were assessed at 21 years using a summarised form of the Composite Abuse Scale. We used the Composite International Diagnostic Interview to obtain lifetime diagnoses of mental health and substance disorders. Multivariable logistic regression models of each IPV form were adjusted for individual, family and neighbourhood factors during adolescence, and for other forms of IPV. We have shown specific links between different forms of IPV experienced and individual substance and mental health disorders. Mental health disorders were related to all three forms of IPV, while alcohol disorders were linked to psychological IPV (ORAUD = 1.86; 1.21-2.86) and illicit substance disorders to physical IPV (ORSUD = 2.07; 1.25-3.43). The co-occurrence of related disorders was strongly linked to psychological and physical IPV. Intimate partner violence was experienced by both men and women. Substance and mental health disorders were associated with specific forms of IPV victimisation, suggesting that screening IPV clients and mental health/substance disorder patients for the converse problems may be important for intervention planning.

Background Objectives were to assess associations between intimate partner violence (IPV), violence during armed conflict (i.e. crisis violence), and probable post-traumatic stress disorder (PTSD). Methods Using a sample of 950 women in rural Côte d’Ivoire, logistic generalized estimating equations assessed associations between IPV and crisis violence exposures with past-week probable PTSD. Results Over one in 5 (23.4%) women reported past-year IPV, and over one in 4 women (26.5%) reported experiencing IPV prior to the past year (i.e. remote IPV). Crisis violence was experienced by 72.6% of women. In adjusted models including demographics, crisis violence (overall and specific forms), and IPV (remote and past-year), women who reported past-year IPV had 3.1 times the odds of reporting probable past-week PTSD (95%CI: 1.8–5.3) and those who reported remote IPV had 1.6 times the odds (95%CI: 0.9–2.7). Violent exposures during the crisis were not significantly associated with probable PTSD (any crisis violence: aOR: 1.04 (0.7–1.5); displacement: aOR: 0.9 (95%CI: 0.5–1.7); family victimization during crisis: aOR: 1.1 (95%CI: 0.8–1.7); personal victimization during crisis: aOR: 1.7 (95%CI: 0.7–3.7)). Conclusion Past-year IPV was more strongly associated with past-week probable PTSD than remote IPV and violence directly related to the crisis. IPV must be considered within humanitarian mental health and psychosocial programming. PMID:24823492

African American women in the United States report intimate partner violence (IPV) more often than the general population of women. Overall, women underreport IPV because of shame, embarrassment, fear of retribution, or low expectation of legal support. African American women may be especially unlikely to report IPV because of poverty, low social support, and past experiences of discrimination. The purpose of this article is to determine the context in which low-income African American women disclose IPV. Consenting African American women receiving Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) services in WIC clinics were randomized to complete an IPV screening (Revised Conflict Tactics Scales-Short Form) via computer-assisted self-interview (CASI) or face-to-face interview (FTFI). Women (n = 368) reported high rates of lifetime and prior-year verbal (48%, 34%), physical (12%, 7%), sexual (10%, 7%), and any (49%, 36%) IPV, as well as IPV-related injury (13%, 7%). Mode of screening, but not interviewer race, affected disclosure. Women screened via FTFI reported significantly more lifetime and prior-year negotiation (adjusted odds ratio [aOR] = 10.54, 3.97) and more prior-year verbal (aOR = 2.10), sexual (aOR = 4.31), and any (aOR = 2.02) IPV than CASI-screened women. African American women in a WIC setting disclosed IPV more often in face-to-face than computer screening, and race-matching of client and interviewer did not affect disclosure. Findings highlight the potential value of face-to-face screening to identify women at risk of IPV. Programs should weigh the costs and benefits of training staff versus using computer-based technologies to screen for IPV in WIC settings. © The Author(s) 2014.

Knowledge on young adults' perceptions of intimate partner violence (IPV) is important as these are the ages at which most people form their first serious intimate relationships and begin to develop norms about how to communicate within a relationship. This study uses an experimental vignette design to examine whether the type of violence employed and the gender dynamics within the couple (male perpetrator and female victim vs. female perpetrator and male victim) affect young adults' perceptions of IPV normality. Gender differences in these perceptions are assessed and moreover, we explore whether these differences can be attributed to respondents' prior IPV experiences. Young adults ( N = 599) were recruited from various schools and universities throughout the Netherlands. They were randomly assigned to one of 10 experimental vignettes. Findings demonstrate that, generally, scenarios describing more serious types of IPV as well as those describing a male perpetrator and a female victim received lower ratings of normality. Gender differences in perceptions were found and, moreover, the direction of these gender differences appeared to depend on the actual gender dynamics described in the IPV scenario. Prior IPV experiences increased perceptions of IPV normality among female respondents in particular. Moreover, the suggestion that respondents' prior IPV experiences may better explain respondents' IPV perceptions than respondents' gender, was only partly supported. Our findings suggest that this is true for respondents' prior psychological, but not physical IPV experiences and for the manipulations of the gender dynamics within the couple, but not so much for the type of violence employed. Implications of these findings are discussed. From a prevention perspective, greater insight into these perceptions is relevant as they have been shown to be related to help-seeking and reporting behavior in the case of experiencing or witnessing IPV.

To investigate if women with a history of having experienced intimate partner violence (IPV) who undertook caregiving would experience worse mental and physical health compared to those without caregiving roles. IPV, caregiving history and data on covariates were collected between 1996 and 2010 from 8453 participants in the Australian Longitudinal Study on Women's Health aged between 45 and 65 over the course of the study. Regression analyses were used to analyse the association of IPV and caregiving (categorised as IPV+caregiving, IPV+no caregiving, no IPV+caregiving, no IPV+no caregiving), with and without adjustment for covariates, on mental and physical health-related quality of life (HRQOL), depressive symptoms and perceived stress, measured in 2010. Experiencing IPV and being a caregiver was associated with poor health outcomes on three of the four outcomes (depressive symptoms, OR 2.08, 95% CI 1.58, 2.75; stress, OR 2.11, 95% CI 1.55, 2.87; physical HRQOL β -2.39, 95% CI -3.34, -1.44; all p≤0.001, fully adjusted) compared with not experiencing IPV or caregiving. On these outcomes, IPV and caregiving combined had a stronger association than IPV or caregiving separately. For mental HRQOL, a weaker association was found (OR 1.41 95% CI 1.02, 1.95, fully adjusted, p=0.04). This paper provides evidence for the cumulative health impact of stressful life events, both those that are perpetrated against an individual (violence) and those undertaken with a degree of personal agency (caregiving). The findings underscore the need to understand the drivers of poor health, for clinicians to ask about life circumstances of patients experiencing poor health, and for the provision of referral pathways for complex cases.

Community-level influences on women's experience of intimate partner violence and terminated pregnancy in Nigeria: a multilevel analysis

PubMed Central

2012-01-01

Background Intimate partner violence (IPV) is a major public health problem with serious consequences for women’s physical, mental, sexual and reproductive health. Reproductive health outcomes such as unwanted and terminated pregnancies, fetal loss or child loss during infancy, non-use of family planning methods, and high fertility are increasingly recognized. However, little is known about the role of community influences on women's experience of IPV and its effect on terminated pregnancy, given the increased awareness of IPV being a product of social context. This study sought to examine the role of community-level norms and characteristics in the association between IPV and terminated pregnancy in Nigeria. Methods Multilevel logistic regression analyses were performed on nationally-representative cross-sectional data including 19,226 women aged 15–49 years in Nigeria. Data were collected by a stratified two-stage sampling technique, with 888 primary sampling units (PSUs) selected in the first sampling stage, and 7,864 households selected through probability sampling in the second sampling stage. Results Women who had experienced physical IPV, sexual IPV, and any IPV were more likely to have terminated a pregnancy compared to women who had not experienced these IPV types. IPV types were significantly associated with factors reflecting relationship control, relationship inequalities, and socio-demographic characteristics. Characteristics of the women aggregated at the community level (mean education, justifying wife beating, mean age at first marriage, and contraceptive use) were significantly associated with IPV types and terminated pregnancy. Conclusion Findings indicate the role of community influence in the association between IPV-exposure and terminated pregnancy, and stress the need for screening women seeking abortions for a history of abuse.

Abstract Background: Intimate partner violence (IPV) and obesity are national public health problems that are potentially associated. We examined the association between IPV exposure and 5-year weight gain in young women. We also examined whether depressive mood conferred additional increases in weight gain. Materials and Methods: Analyses were conducted among women in Project EAT, a longitudinal cohort study of weight-related health, which has collected data at three 5-year survey waves: “EAT I” (mean age 15 years), “EAT II” (mean age 19 years), and “EAT III” (mean age 25 years). Height and body weight were self-reported at each survey wave. IPV victimization and depressive mood were assessed on the EAT II survey. The study comprised women with data on IPV and body mass index (BMI) (N = 619). Linear regression analyses examined (1) 5-year (EAT II to EAT III) BMI change as a function of IPV exposure and (2) 5-year BMI change as a function of depressive mood at EAT II in women with and without IPV exposure. Results: Almost 20% of the study sample reported IPV. Women exposed to both physical and sexual IPV at EAT II gained 1.1 kg/m2 (95% CI −0.2 to 2.4) more, over 5 years, than women unexposed to IPV, although this did not reach statistical significance. Among those with IPV exposure, depressive mood at EAT II was associated with an additional increase in BMI of 1.8 kg/m2 (95% CI 0.2–3.4) relative to no depressive mood. Conclusion: Survivors of IPV with depressive mood may have accelerated weight gain. Trauma-informed obesity prevention strategies may be warranted in this group. PMID:28075656

Impact of Intimate Partner Violence on Infant Temperament.

Intimate partner violence (IPV) during the first year postpartum is common in Bangladesh, and many infants are exposed to hostile and aggressive environment. The aim of the current study was to investigate how IPV (physical, emotional, and sexual) impacts on the mother's perception of her infant's temperament 6 to 8 months postpartum, and whether maternal depressive symptom at 6 to 8 months postpartum is a mediator in this association. A total of 656 rural Bangladeshi women and their children 6 to 8 months postpartum were included in this study. Data were collected by structured interviews. The women were asked about physical, sexual, and emotional IPV; depressive symptoms (Edinburgh Postnatal Depressive Symptoms [EPDS]); and their perception of infant temperament assessed by the Infant Characteristic Questionnaire (ICQ). Descriptive analyses were conducted for prevalence of IPV and maternal depressive symptoms. Mediation analysis was conducted with a series of linear regressions with types of IPV as independent variables, ICQ including its subscales as dependent variables and maternal depressive symptoms as potential mediator. All the analyses were adjusted for the woman's and her husband's ages and number of children of the couple. Nearly 90% of the mothers reported some kind of IPV at 6 to 8 months postpartum. All types of IPV were directly associated with the mother's perception of her infant as unadaptable. Maternal depressive symptom was a mediating factor between physical IPV and the ICQ subscales fussy-difficult and unpredictable. In addition, depressive symptoms mediated between sexual and emotional IPV, and the mother's perception of the infant as unpredictable. The results showed that IPV influenced how mothers perceived their infant's temperament. It is important that health care professionals at maternal and child health services enquire about IPV with possibilities to refer the family or the mother and infant for appropriate support.
