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.

Childhood Trauma and Dissociative Intimate Partner Violence.

PubMed

Webermann, Aliya R; Murphy, Christopher M

2018-04-01

The present study assesses childhood abuse/neglect as a predictor of dissociative intimate partner violence (IPV) among 118 partner-abusive men. One third (36%) endorsed dissociative IPV, most commonly losing control (18%), surroundings seeming unreal (16%), feeling someone other than oneself is aggressing (16%), and seeing oneself from a distance aggressing (10%). Childhood physical abuse/neglect predicted IPV-specific derealization/depersonalization, aggressive self-states, and flashbacks to past violence. Childhood emotional abuse/neglect predicted derealization/depersonalization, blackouts, and flashbacks. Childhood sexual abuse uniquely predicted amnesia. Other potential traumas did not predict dissociative IPV, suggesting dissociative IPV is influenced by trauma-based emotion dysregulation wherein childhood abuse/neglect survivors disconnect from their abusive behavior.

Safety data from countries with experience in the use of inactivated poliovirus vaccine (IPV) are important for the global polio eradication strategy to introduce IPV into the immunisation schedules of all countries. In the USA, IPV has been included in the routine immunisation schedule since 1997. We aimed to analyse adverse events after IPV administration reported to the US Vaccine Adverse Event Reporting System (VAERS). We analysed all VAERS data associated with IPV submitted between Jan 1, 2000, and Dec 31, 2012, either as individual or as combination vaccines, for all age and sex groups. We analysed the number and event type (non-serious, non-fatal serious, and death reports) of individual reports, and explored the most commonly coded event terms to describe the adverse event. We classified death reports according to previously published body-system categories (respiratory, cardiovascular, neurological, gastrointestinal, other infectious, and other non-infectious) and reviewed death reports to identify the cause of death. We classified sudden infant death syndrome as a separate cause of death considering previous concerns about sudden infant syndrome after vaccines. We used empirical Bayesian data mining methods to identify disproportionate reporting of adverse events for IPV compared with other vaccines. Additional VAERS data from 1991 to 2000 were analysed to compare the safety profiles of IPV and oral poliovirus vaccine (OPV). Of the 41,792 adverse event reports submitted, 39,568 (95%) were for children younger than 7 years. 38,381 of the reports for children in this age group (97%) were for simultaneous vaccination with IPV and other vaccines (most commonly pneumococcal and acellular pertussis vaccines), whereas standalone IPV vaccines accounted for 0·5% of all reports. 34,880 reports were for non-serious events (88%), 3905 reports were for non-fatal serious events (10%), and 783 reports were death reports (2%). Injection-site erythema was the most commonly coded term for non-serious events (29%), and pyrexia for non-fatal serious events (38%). Most deaths (96%) were in children aged 12 months or younger; most (52%) had sudden infant death syndrome as the reported cause of death. The safely profiles of combined IPV and whole-cell pertussis vaccines, OPV and whole-cell pertussis vaccines, and OPV and acellular pertussis vaccines were similar. We noted no indication of disproportionate reporting of adverse events after immunisation with IPV-containing vaccines compared with other vaccines between 1990 and 2013. Fairly few adverse events were reported for the more than 250 million IPV doses distributed between 2000 and 2012. Sudden infant death syndrome reports after IPV were consistent with reporting patterns for other vaccines. No new or unexpected vaccine safety problems were identified for fatal, non-fatal serious, and non-serious reports in this assessment of adverse events after IPV. None. Copyright © 2015 Elsevier Ltd.

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.

Validation testing of the NASA Lewis 125 Ah advanced design individual pressure vessel (IPV) nickel-hydrogen flight cells was conducted. Work consisted of characterization, storage, and cycle life testing. There was no capacity degradation after 52 days of storage with the cells in the discharged state, an open circuit, 0 C, and a hydrogen pressure of 14.5 psia. The catalyzed wall wick cells were cycled for over 11,000 cycles with no cell failures in the continuing test. One of the noncatalyzed wall wick cells failed.

Alcohol and drug abuse in men who sustain intimate partner violence

Extensive work has documented an association between sustaining intimate partner violence (IPV) and alcohol/drug abuse among women, yet little research has documented the same association in men, even though men comprise 25%–50% of all IPV victims in a given year. The present study investigates the associations among sustaining IPV and alcohol/drug abuse among both a clinical and community sample of men. The clinical sample is comprised of 302 men who sustained intimate terrorism -- a form of IPV that is characterized by much violence and controlling behavior -- from their female partners and sought help. The community sample is comprised of 520 men, 16% of whom sustained common couple violence, a lower level of more minor, reciprocal IPV. Analyses showed that among both groups of men who sustained IPV, the prevalence and frequency of alcohol/drug abuse was significantly higher than in men who did not sustain IPV. However, a dose-response relationship between sustaining IPV and alcohol/drug abuse was found only among men in the community sample. Path modeling showed that for the community sample, the best fitting models were ones that showed that the alcohol/drug abuse predicted IPV victimization, an association that was fully mediated by their use of IPV.

Childhood victimization experiences are common among intimate partner violence (IPV) victims. This study examines the link between childhood physical and sexual victimization experiences and adulthood IPV among Korean immigrant women in the USA. As Korean immigrants often use physical punishment to discipline their children, and reporting sexual abuse is discouraged due to stigmatization in this community, cultural factors (e.g. patriarchal values) related to childhood victimization and IPV were also examined. Survey data from Korean immigrant women in the USA were collected. Using a case-control design, we compared 64 Korean immigrant women who have experienced IPV in the past year with 63 Korean immigrant women who have never experienced IPV in their lifetime. The findings of this study reveal that IPV victims, compared with non-victims, experienced higher childhood victimization rates. Logistic regression analysis demonstrated that childhood victimization and patriarchal gender ideology strongly predict IPV victimization among Korean immigrants. However, patriarchal values did not moderate the relationship between childhood victimization and IPV. To prevent IPV among Korean immigrant population, we need to make special efforts to prevent childhood abuse and change ingrained cultural attitudes about child physical and sexual abuse among immigrant communities through culturally sensitive programs.

Women who experience intimate partner violence (IPV) may be at elevated risk for poor sexual health outcomes, including sexually transmitted infections (STIs). This association, however, has not been consistently demonstrated in low-income or post-conflict countries. Furthermore, the role that attitudes towards IPV play in sexual-health outcomes and behaviour has rarely been examined. We examined associations between IPV experiences, accepting attitudes towards physical IPV, and sexual-health and behavioural outcomes among 592 young women in post-conflict Liberia. Participants' experiences with either moderate or severe physical violence or sexual violence were common. Additionally, accepting attitudes towards physical IPV were positively associated with reporting STI symptoms, IPV experiences and the ability to negotiate safe sex. Findings suggest that for sexual-health-promotion and risk-reduction-intervention efforts to achieve full impact, interventions must address the contextual influence of violence, including individual attitudes toward IPV.

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 paper introduces the common intrusion detection technologies, discusses the work flow of Snort intrusion detection system, and analyzes IPv6 data packet encapsulation and protocol decoding technology. We propose the expanding Snort architecture to support IPv6 intrusion detection in accordance with CIDF standard combined with protocol analysis technology and pattern matching technology, and present its composition. The research indicates that the expanding Snort system can effectively detect various intrusion attacks; it is high in detection efficiency and detection accuracy and reduces false alarm and omission report, which effectively solves the problem of IPv6 intrusion detection.

Intimate partner violence (IPV) during pregnancy may be common in settings where HIV is prevalent but there are few data on IPV in populations of HIV-infected pregnant women in Southern Africa. We examined the prevalence and correlates of IPV among HIV-infected pregnant women. A primary care antenatal clinic in Cape Town, South Africa. 623 consecutive HIV-infected pregnant women initiating lifelong antiretroviral therapy. IPV, depression, substance use and psychological distress were assessed using the 13-item WHO Violence Against Women questionnaire, the Edinburgh Postnatal Depression Scale (EPDS), Alcohol and Drug Use Disorders Identification Tests (AUDIT/DUDIT) and the Kessler 10 (K-10) scale, respectively. The median age in the sample was 28 years, 97% of women reported being in a relationship, and 70% of women reported not discussing and/or agreeing on pregnancy intentions before conception. 21% of women (n=132) reported experiencing ≥1 act of IPV in the past 12 months, including emotional (15%), physical (15%) and sexual violence (2%). Of those reporting any IPV (n=132), 48% reported experiencing 2 or more types. Emotional and physical violence was most prevalent among women aged 18-24 years, while sexual violence was most commonly reported among women aged 25-29 years. Reported IPV was less likely among married women, and women who experienced IPV were more likely to score above threshold for substance use, depression and psychological distress. In addition, women who reported not discussing and/or not agreeing on pregnancy intentions with their partner prior to conception were significantly more likely to experience violence. HIV-infected pregnant women in the study reported experiencing multiple forms of IPV. While the impact of IPV on maternal and child health outcomes in the context of HIV infection requires further research attention, IPV screening and support services should be considered within the package of routine care for HIV-infected pregnant women.

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.

Violence against women is recognized by globally as a serious health and social problem that impedes development. To determine the magnitude of physical intimate partner violence against women in six selected communities from Chile, Egypt, India and the Philippines. Population-based household surveys. Selected urban communities in Temuco, Chile; Ismailia, Egypt; Lucknow, Trivandrum, and Vellore non-slum areas of India; and in Manila, the Philippines. Women aged 15-49 years who cared for at least one child younger than 18 years old. The number of participants per community was 442 (Santa Rosa, Chile), 631 (El-Sheik Zayed, Egypt), 506 (Lucknow, India), 700 (Trivandrum, India), 716 (Vellore, India) and 1000 (Paco, the Philippines). Lifetime and Current physical intimate partner violence (IPV) was measured using standard definitions and four behaviors of actions--namely slap, hit, kick and beat. Three derived variables for severity included: disabling IPV, IPV-related injury requiring health care and multiple severe IPV (presence of hit and kick and beat). Percentages of lifetime and current physical intimate partner violence (IPV) against women in our sample of 3975 were as follows: 24.9 and 3.6 (Santa Rosa), 11.1 and 10.5 (El-Sheik Zayed), 34.6 and 25.3 (Lucknow), 43.1 and 19.6 (Trivandrum) 31.0 and 16.2 (Vellore), and 21.2 and 6.2 (Paco). Multiple severe physical IPV was more common in the three communities within India (9.0%, 5.9% and 8.0% in Trivandrum, Lucknow and Vellore) than the other three communities (Santa Rosa 2.1%; El-Sheik Zayed 2.9% and Paco 1.9%). Physical IPV was found to be a common phenomenon in all six communities. Overall, patterns of IPV behaviors were similar among the six communities.

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

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.

Intimate partner violence (IPV) perpetration is common among men who use substances. Substance use is a contributing factor for IPV perpetration. This cross-sectional study determined lifetime prevalence and factors associated with ever perpetrating IPV by men receiving substance use treatment in Brazil (n = 281) and England (n = 223). IPV, adverse childhood experiences, attitudes towards gender relations and roles, current health state, substance use, depressive symptoms and anger expression were assessed. Logistic regression determined factors associated with ever perpetrating any (emotional, physical and/or sexual) IPV. Multinomial logistic regression determined factors associated with ever perpetrating different types of IPV. 74.6% (373/500) reported ever perpetrating IPV: 16.5% (82/498) emotional IPV only, 46.4% (231/498) physical IPV (with/without emotional IPV) and 11.6% (58/498) sexual IPV (with/without emotional and/or physical IPV). Higher anger expression, higher depressive symptoms, fighting physically with another man in the past year (Brazil only), experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score (England only) predicted ever perpetrating IPV. Compared to never perpetrating any IPV, anger expression was associated with emotional and physical IPV perpetration; fighting physically with another man in the past year was associated with physical IPV perpetration and experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score were associated with both physical and sexual IPV perpetration. Integrated interventions that address IPV and substance use delivered in substance use treatment could improve outcomes for perpetrators and victims.[Gilchrist G, Radcliffe P, Noto AR, d'Oliveira AFPL.

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.

We tested an integrative model of individual and dyadic variables contributing to intimate partner violence (IPV) perpetration. Based on the vulnerability-stress-adaptation (VSA) model, we hypothesized that three “enduring vulnerabilities” (i.e., antisocial behavior, hostility, and depressive symptoms) would be associated with a “maladaptive process” (i.e., negative relationship attributions) that would lead to difficulties in couple conflict resolution, thus leading to IPV. Among a community sample of 167 heterosexual couples who were expecting their first child, we used an actor-partner interdependence model to account for the dyadic nature of conflict and IPV, as well as a hurdle count model to improve upon prior methods for modeling IPV data. Study results provided general support for the integrative model, demonstrating the importance of considering couple conflict in the prediction of IPV and showing the relative importance of multiple predictor variables. Gender symmetry was observed for the prediction of IPV occurrence, with gender differences emerging in the prediction of IPV frequency. Relatively speaking, the prediction of IPV frequency appeared to be a function of enduring vulnerabilities among men, but a function of couple conflict among women. Results also revealed important cross-gender effects in the prediction of IPV, reflecting the inherently dyadic nature of IPV, particularly in the case of “common couple violence.” Future research using longitudinal designs is necessary to verify the conclusions suggested by the current results.

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.

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

Background Although studies suggest the relevance of intimate partner violence (IPV) and other health-related social characteristics as risk factors for postpartum mental health, literature lacks evidence about how these are effectively connected. This study thus aims to explore how socio-economic position, maternal age, household and marital arrangements, general stressors, alcohol misuse and illicit drug abuse, and especially psychological and physical IPV relate in a framework leading to postpartum common mental disorder (CMD). Methods The study was carried out in five primary health care units of Rio de Janeiro, Brazil, and included 810 randomly selected mothers of children up to five postpartum months waiting for pediatric visits. The postulated pathways between exposures and outcome were based on literature evidence and were further examined using structural equation models. Results Direct pathways to postpartum CMD arose from a latent variable depicting socio-economic position, a general stressors score, and both IPV variables. Notably, the effect of psychological IPV on postpartum CMD ran partly through physical IPV. The effect of teenage pregnancy, conjugal instability and maternal burden apparently happens solely through substance use, be it alcohol misuse, illicit drug abuse or both in tandem. Moreover, the effect of the latter on CMD seems to be entirely mediated through both types of IPV. Conclusion Although the theoretical model underlying the analysis still requires in-depth detailing, results of this study may have shed some light on the role of both psychological and physical IPV as part of an intricate network of events leading to postpartum CMD. Health initiatives may want to make use of this knowledge when designing preventive and intervention approaches. PMID:24884951

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.

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

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.

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.

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.

Background Women bear a significant burden of the HIV epidemic in the United States. Women classified as ‘HIV high-risk’ often bring co-existing histories of intimate partner violence (IPV), drug use, and transactional sex. To help inform future comprehensive HIV prevention strategies, we aimed to explore common motivating reasons and barriers to leaving and/or terminating engagement in each of these risk-promoting situations. Methods Between August and November 2014, in-depth interviews were conducted with 14 HIV high-risk women in Atlanta, Georgia who had experienced IPV in the previous 12 months, and used drugs and/or engaged in transactional sex in the previous five years. Participants were asked about histories of IPV, drug use, and/or engagement in transactional sex, and the motivating reasons and barriers to terminating each. Results Women reported a range of motivating reasons for leaving IPV, drug use, and transactional sex. Overlapping themes included impact on children, personal physical health/safety, and life dissatisfaction. Financial need was identified as a common barrier to leaving. Conclusions Future HIV prevention research should further explore the perceived impact of IPV, drug use, and transactional sex on physical health/safety, life dissatisfaction, one’s children, and financial need as motivators and barriers to reducing upstream HIV risk.

Perinatal intimate partner violence (IPV) is common and has significant negative health outcomes for mothers and infants. This study evaluated the effectiveness of an IPV intervention in reducing violence among abused women in perinatal home visiting programs. This assessor-blinded multisite randomized control trial of 239 women experiencing perinatal IPV was conducted from 2006 to 2012 in U.S. urban and rural settings. The Domestic Violence Enhanced Home Visitation Program (DOVE) intervention group (n = 124) received a structured abuse assessment and six home visitor-delivered empowerment sessions integrated into home visits. All participants were screened for IPV and referred appropriately. IPV was measured by the Conflicts Tactics Scale2 at baseline through 24 months postpartum. There was a significant decrease in IPV over time (F = 114.23; p < 0.001) from baseline to 1, 3, 6, 12, 18, and 24 months postpartum (all p < 0.001). Additional models examining change in IPV from baseline indicated a significant treatment effect (F = 6.45; p < 0.01). Women in the DOVE treatment group reported a larger mean decrease in IPV scores from baseline compared to women in the usual care group (mean decline 40.82 vs. 35.87). All models accounted for age and maternal depression as covariates. The DOVE intervention was effective in decreasing IPV and is brief, thereby facilitating its incorporation within well-woman and well-child care visits, as well as home visiting programs, while satisfying recommendations set forth in the Affordable Care Act for IPV screening and brief counseling.

A large body of research has established a relationship between trauma exposure, particularly during childhood, and psychotic experiences. Yet, there remains a general lack of research on adult trauma exposure, including intimate partner violence (IPV), as a risk factor for psychotic experiences. The purpose of this study is to investigate the association between IPV and psychotic experiences in U.S. cities. Data were collected from 1615 participants in four U.S. cities. Psychotic experiences were assessed through the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) psychosis screen along with adapted IPV measures. Findings revealed that experiencing at least one form of IPV was significantly associated with each of the four psychotic experiences assessed for both men and women. The strongest associations were found for threatening and sexual IPV; physical IPV was not significantly associated with psychotic experiences. Exposure to IPV was associated with more than a tripling of the odds of reporting at least one psychotic experience as opposed to none. Among those exposed to IPV there was between three- to five times the odds of reporting specific subtypes of psychotic experiences. The results expand on prior findings linking psychotic experiences and childhood trauma exposure to include intimate adult exposures. Emotional and sexual IPV appear to be associated with elevated risk for psychotic experiences in adulthood. Even though IPV is more commonly reported by women in the U.S., such victimization appears to have similar associations with psychotic experiences regardless of gender. Copyright © 2017 Elsevier B.V.

Male perpetration of intimate partner violence (IPV) against women in Tanzania is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, although research on this topic in sub-Saharan Africa is limited. Grounded in social learning theory, social influence theory, and the theory of gender and power, the purpose of this study was to examine whether and how peer networks influence men's perpetration of IPV in Dar es Salaam, Tanzania. We conducted in-depth interviews (n = 40) with a sub-sample of 20 men enrolled in the control condition of an ongoing cluster-randomised controlled trial. We purposively sampled participants who previously reported perpetrating physical IPV. To analyse the data, we generated narrative summaries and conducted thematic and interpretative coding. We saw no evidence that men self-selected into peer networks with certain values or behaviours. Rather, men described several mechanisms through which their peers influenced the perpetration of IPV, including: (1) the internalisation of peer network norms, (2) pressure to conform to peer network norms and (3) the direct involvement of peers in shaping couple power dynamics. Our findings suggest that peer networks influence men's perpetration of IPV and should be targeted in future programmes and interventions.

Bangladesh reports one of the highest rates of intimate partner violence (IPV) in the world. Despite wide recognition of IPV as an important public health and human rights issue, evidence for IPV prevention is still inadequate. Lack of guidance on effective IPV prevention in Bangladesh resulted in targeting only women in most of the programmes. This paper assesses impact of SAFE, a 20-month intervention (March 2012 to October 2013) in slums of Dhaka on IPV and tests effectiveness of female only groups vs. no groups; and female + male groups vs. female only groups on IPV in the community using a three-arm cluster randomized controlled trial. SAFE's core activities included interactive group sessions, community mobilisation, and services. The last two activities were common across arms. Regression analyses (female survey: baseline n = 2,666; endline n = 2,670) showed no effect of SAFE on IPV against women aged 15-29. However, sub-group analyses demonstrated 21% risk reduction of physical IPV against adolescent girls aged 15-19 in the female + male group intervention arm. A consistent reduction in sexual violence was observed in both female and female + male arms for both groups of women, but the results were not statistically significant. The findings emphasise the importance of combining male and female interventions for reducing physical IPV against adolescent girls. Implications for future research have been discussed.

Background Intimate partner violence against women (IPV) has been identified as a serious public health problem. Although the health care system is an important site for identification and intervention, there have been challenges in determining how health care professionals can best address this issue in practice. We surveyed nurses and physicians in 2004 regarding their attitudes and behaviours with respect to IPV, including whether they routinely inquire about IPV, as well as potentially relevant barriers, facilitators, experiential, and practice-related factors. Methods A modified Dillman Tailored Design approach was used to survey 1000 nurses and 1000 physicians by mail in Ontario, Canada. Respondents were randomly selected from professional directories and represented practice areas pre-identified from the literature as those most likely to care for women at the point of initial IPV disclosure: family practice, obstetrics and gynecology, emergency care, maternal/newborn care, and public health. The survey instrument had a case-based scenario followed by 43 questions asking about behaviours and resources specific to woman abuse. Results In total, 931 questionnaires were returned; 597 by nurses (59.7% response rate) and 328 by physicians (32.8% response rate). Overall, 32% of nurses and 42% of physicians reported routinely initiating the topic of IPV in practice. Principal components analysis identified eight constructs related to whether routine inquiry was conducted: preparedness, self-confidence, professional supports, abuse inquiry, practitioner consequences of asking, comfort following disclosure, practitioner lack of control, and practice pressures. Each construct was analyzed according to a number of related issues, including clinician training and experience with woman abuse, area of practice, and type of health care provider. Preparedness emerged as a key construct related to whether respondents routinely initiated the topic of IPV. Conclusion The present study provides new insight into the factors that facilitate and impede clinicians' decisions to address the issue of IPV with their female patients. Inadequate preparation, both educational and experiential, emerged as a key barrier to routine inquiry, as did the importance of the "real world" pressures associated with the daily context of primary care practice.

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

The facial region has been the most common site of injury following violent episodes. The purpose of this study was to determine the prevalence and pattern of maxillofacial injuries associated with intimate partner violence (IPV) in women treated at a single facility in Malaysia. A retrospective review of 242 hospital records of female IPV victims who were seen at the One-Stop Crisis Centre (OSCC) in Hospital Raja Perempuan Zainab II, Kelantan over a two-year period (January 1, 2005 to December 31, 2006) was performed. A structured form was used for data collection. Information regarding the anatomical sites of injuries, types of injuries, and mechanisms of assault were obtained. Most victims were married (85.1%), were injured by the husband (83.5%), and had at least one previous IPV episode (85.5%). Injury to the maxillofacial region was the most common (50.4%), followed by injury to the limbs (47.9%). In 122 cases of maxillofacial injuries, the middle of the face was most frequently affected (60.6%), either alone or in combination with the upper or lower third of the face. Injury to soft tissues (contusions, abrasions and lacerations) was the most common (87.7%). This study indicates there is a high prevalence of maxillofacial injuries associated with IPV among women treated at the OSCC in Kelantan, Malaysia.

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.

Women's Work, Gender Roles, and Intimate Partner Violence in Nigeria.

The purpose of this study was to determine the contribution of women's labor force participation to the risk of intimate partner violence (IPV) victimization in the past 12 months, using data for 20,635 currently married women aged 15-49 years from the 2013 nationally representative Nigeria Demographic and Health Survey. Multilevel logistic regression models of sexual and physical IPV, with interactions between women's work and social norms regarding traditional gender roles, were developed. Approximately 23% of women aged 15-49 years reported IPV victimization in the past 12 months. Results revealed that non-cash work relative to unemployment was positively associated with both forms of IPV victimization, after controlling for other factors. Women's engagement in cash work was positively correlated with sexual IPV. The positive association between cash work and physical IPV victimization was significantly larger for women who resided in localities with greater male approval of wife beating. In localities where husband-dominated decision making was more common, a spousal education gap that favored husbands was more positively associated with sexual IPV. The findings call for integrated IPV prevention and economic empowerment programs that consider gender norms and gender-role beliefs and are adapted to the locality setting, in order to promote social environments in which women can reap the full benefits of their economic empowerment.

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.

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

Testing the woman abuse screening tool to identify intimate partner violence in Indonesia.

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.

The objectives of this study were to identify intimate partner violence (IPV) incidence rates, to quantify specific risks and characteristics of these incidents and the environments in which they occur, to identify how often children are present for or injured during these incidents, and to identify differences in victim reports of IPV to law enforcement officers at the scene of the incident compared with previously published reports of IPV from retropsective, anonymous surveys and domestic violence shelter interviews. Data gathered by responding law enforcement officers at the scene of the IPV incident were used to determine the prevalence of IPV incident characteristics and outcomes. Females aged 20 to 39 years, unmarried adults, and African Americans were disproportionately represented as victims of IPV in this study. IPV incidents were significantly more likely to occur on Saturdays and Sundays and during the months of May through August. Relationship durations for suspect-victim pairs were most often less than 12 months at the time of the incident. Weapon use and/or strangulation was common, occurring in 44% of all incidents. Minors (under age 18 years) were frequently present in the home during the IPV incident or a member of the household (59%). This study provides a unique perspective of IPV by utilizing data collected directly from the scene of the incident by first responders. Previously published characteristics of IPV were confirmed, but this study also brings to light new and critical information concerning this prevalent form of violence. Study findings relating to incidence, seasonality, severity, disproportionately affected populations, and child exposure are discussed.

Exposure to intimate partner violence (IPV) is known to challenge children's optimal development. This study sought to associate participants' beliefs about IPV held during childhood with their adjustment as adults, and to compare their beliefs from childhood to their beliefs in early adulthood. A nationally representative sample of 703 Swedish young adults reported on their past and present beliefs about the causes of their parents' IPV. Standardized measures assessed their mental health (anxiety, depression, and traumatic stress symptoms) and the quality of their relationships as adults. The most common explanations for IPV were that the perpetrator suffered from physical or mental illness, had relationship problems, or was distressed. Participants were less likely to blame themselves for IPV or to believe that the perpetrator was cruel when they were adults, compared to their reports of themselves as children. Women were more likely to attribute mental or physical illness as the cause of the perpetrator's IPV. Childhood beliefs that the perpetrator was debilitated (from mental illness or substance abuse) and cruel (took pleasure in violence and/or despised the child) were associated with greater mental health problems and poorer relationship quality in adulthood. Evaluation of children's harmful beliefs about IPV could be useful in adapting intervention services aimed at ameliorating negative personal causal attributions. © 2016 Wiley Periodicals, Inc.

Methods for the Quality Control of Inactivated Poliovirus Vaccines.

PubMed

Wilton, Thomas

2016-01-01

Inactivated poliovirus vaccine (IPV) plays an instrumental role in the Global Poliovirus Eradication Initiative (GPEI). The quality of IPV is controlled by assessment of the potency of vaccine batches. The potency of IPV can be assessed by both in vivo and in vitro methods. In vitro potency assessment is based upon the assessment of the quantity of the D-Antigen (D-Ag) units in an IPV. The D-Ag unit is used as a measure of potency as it is largely expressed on native infectious virions and is the protective immunogen. The most commonly used in vitro test is the indirect ELISA which is used to ensure consistency throughout production.A range of in vivo assays have been developed in monkeys, chicks, guinea pigs, mice, and rats to assess the potency of IPV. All are based on assessment of the neutralizing antibody titer within the sera of the respective animal model. The rat potency test has become the favored in vivo potency test as it shows minimal variation between laboratories and the antibody patterns of rats and humans are similar. With the development of transgenic mice expressing the human poliovirus receptor, immunization-challenge tests have been developed to assess the potency of IPVs. This chapter describes in detail the methodology of these three laboratory tests to assess the quality of IPVs.

Increased risk of miscarriage among women experiencing physical or sexual intimate partner violence during pregnancy in Guatemala City, Guatemala: cross-sectional study

PubMed Central

2011-01-01

Background Violence against women by their male intimate partners (IPV) during pregnancy may lead to negative pregnancy outcomes. We examined the role of IPV as a potential risk factor for miscarriage in Guatemala. Our objectives were: (1) To describe the magnitude and pattern of verbal, physical and sexual violence by male intimate partners in the last 12 months (IPV) in a sample of pregnant Guatemalans; (2) To evaluate the influence of physical or sexual IPV on miscarriage as a pregnancy outcome. Methods All pregnant women reporting to the maternity of a major tertiary care public hospital in Guatemala City from June 1st to September 30th, 2006 were invited to participate in this cross-sectional study. The admitting physician assessed occurrence of miscarriage, defined as involuntary pregnancy loss up to and including 28 weeks gestation. Data on IPV, social and demographic characteristics, risk behaviours, and medical history were collected by interviewer-administered questionnaire. Laboratory testing was performed for HIV and syphilis. The relationship between IPV and miscarriage was assessed through multivariable logistic regression. Results IPV affected 18% of the 1897 pregnant Guatemalan women aged 15-47 in this sample. Verbal IPV was most common (16%), followed by physical (10%) and sexual (3%) victimisation. Different forms of IPV were often co-prevalent. Miscarriage was experienced by 10% of the sample (n = 190). After adjustment for potentially confounding factors, physical or sexual victimisation by a male intimate partner in the last 12 months was significantly associated with miscarriage (ORadj 1.1 to 2.8). Results were robust under a range of analytic assumptions. Conclusions Physical and sexual IPV is associated with miscarriage in this Guatemalan facility-based sample. Results cohere well with findings from population-based surveys. IPV should be recognised as a potential cause of miscarriage. Reproductive health services should be used to screen for spousal violence and link to assistance. PMID:21733165

Both intimate partner violence (IPV) and community violence are prevalent globally, and each is associated with serious health consequences. However, little is known about their potential links or the possible benefits of coordinated prevention strategies. Using aggregated data on community violence from the São Paulo State Security Department (INFOCRIM) merged with WHO multi-country study on women's health and domestic violence data, random intercept models were created to assess the effect of crime on women's probability of experiencing IPV. The association between IPV and male aggression (measured by women's reports of their partner's fights with other men) was examined using logistic regression models. We found little variation in the likelihood of male IPV perpetration related to neighborhood crime level but did find an increased likelihood of IPV experiences among women whose partners were involved in male-to-male violence. Emerging evidence on violence prevention has suggested some promising avenues for primary prevention that address common risk factors for both perpetration of IPV and male interpersonal violence. Strategies such as early identification and effective treatment of emotional disorders, alcohol abuse prevention and treatment, complex community-based interventions to change gender social norms and social marketing campaigns designed to modify social and cultural norms that support violence may work to prevent simultaneously male-on-male aggression and IPV. Future evaluations of these prevention strategies should simultaneously assess the impact of interventions on IPV and male interpersonal aggression.

Intrapulmonary percussive ventilation vs incentive spirometry for children with neuromuscular disease.

2005-06-01

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.

Background The facial region has been the most common site of injury following violent episodes. The purpose of this study was to determine the prevalence and pattern of maxillofacial injuries associated with intimate partner violence (IPV) in women treated at a single facility in Malaysia. Methods A retrospective review of 242 hospital records of female IPV victims who were seen at the One-Stop Crisis Centre (OSCC) in Hospital Raja Perempuan Zainab II, Kelantan over a two-year period (January 1, 2005 to December 31, 2006) was performed. A structured form was used for data collection. Information regarding the anatomical sites of injuries, types of injuries, and mechanisms of assault were obtained. Results Most victims were married (85.1%), were injured by the husband (83.5%), and had at least one previous IPV episode (85.5%). Injury to the maxillofacial region was the most common (50.4%), followed by injury to the limbs (47.9%). In 122 cases of maxillofacial injuries, the middle of the face was most frequently affected (60.6%), either alone or in combination with the upper or lower third of the face. Injury to soft tissues (contusions, abrasions and lacerations) was the most common (87.7%). Conclusions This study indicates there is a high prevalence of maxillofacial injuries associated with IPV among women treated at the OSCC in Kelantan, Malaysia. PMID:20492720

2015-12-01

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.

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.

Intimate partner violence (IPV) is a serious public health problem among adolescents. This study investigated the prevalence of and factors associated with Grade 8 girls' experience and boys' perpetration of IPV in South Africa. Participants were interviewed using interviewer-administered questionnaires about IPV, childhood violence, bullying, gender attitudes, alcohol use and risky sexual behaviours. Multiple logistic regression analysis was conducted to assess factors associated with girls' experience and boys' perpetration of IPV. Structural equation modelling (SEM) was conducted to assess the pathways to IPV experience and perpetration. Results show dating relationships are common among girls (52.5%) and boys (70.7%) and high prevalence of sexual or physical IPV experience by girls (30.9%; 95% CI: 28.2-33.7) and perpetration by boys (39.5%; 95% CI: 36.6-42.3). The logistic regression model showed factors associated with girls' experience of IPV include childhood experience of violence, individual gender inequitable attitudes, corporal punishment at home and in school, alcohol use, wider communication with one's partner and being more negative about school. We found three pathways from childhood trauma to IPV experience and perpetration in both models and these are through inequitable gender attitudes and risky sex, bullying and alcohol use. Prevention of IPV in children needs to encompass prevention of exposure to trauma in childhood and addressing gender attitudes and social norms to encourage positive disciplining approaches. : The trial is registered on ClinicalTrials.gov as NCT02349321. © The Author 2015.

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

Research about the association between early marriage and intimate partner violence (IPV) in low-income countries has yielded conflicting evidence. The aim of this study was to describe the prevalence of and associations between early marriage, and IPV among adolescents and young adults in Viet Nam. Secondary analysis of data from the national Survey Assessment of Viet Namese Youth-Round II (SAVY-II) conducted in 2009-2010, which assessed a representative cohort of people aged 14 to 25 years recruited via a systematic household survey was undertaken. Prevalence was established using descriptive statistics. The association between early marriage and IPV was examined using multiple logistic regressions, adjusting for potential risk factors. Of 10,044 participants, 1,701 had ever married and were included in analyses. Early marriage (before age 18), and experiences of verbal, physical, or sexual IPV were more common among females than males. More young married men than women reported experiences of controlling behaviors by their partners. Early marriage, being illiterate, and exposure to sexual abuse were associated with experience of IPV among young females, but not among young males. Poverty and exposure to family violence was associated with IPV in both sexes. Addressing early marriage, low educational opportunities for girls, childhood sexual abuse, family violence, and poverty should be considered in strategies to reduce IPV in Viet Nam.

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.

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.

Supportive care for survivors of intimate partner violence (IPV) remains limited in primary care settings. Low-income and Spanish-speaking survivors of IPV are even more disadvantaged, given the dearth of linguistically and culturally appropriate interventions for IPV. We conducted semi-structured individual interviews with 17 healthcare workers, including physicians, nurses, and social workers, to describe how healthcare workers serving primarily low-income, Latina populations are currently screening and responding to IPV disclosure, and to explore the acceptability of integrating an interactive, personalized safety decision aid application-myPlan app-into the clinic setting. Despite recognition of IPV as a problem, none of the clinical sites had a protocol to guide screening and response to IPV disclosure. Screening practices varied across the sites, sometimes conducted by medical assistants prior to the provider visit and other times by the physician or nurse provider. When IPV was disclosed, it was often during assessment for a presenting problem such as poor sleep or anxiety. Most healthcare workers felt that clinical and community resources were limited for their patients experiencing IPV. The "warm hand-off" to a social worker was the most common response strategy when possible; otherwise, women were given information about available resources such as hotlines and safe houses. We discuss structural, family, and individual barriers to accessing safety resources for underserved women and review how an easily accessible safety decision app, such as myPlan, could be a resource for women to safely tailor an action plan for her situation. © 2018 Wiley Periodicals, Inc.

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

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.

Objective. We assessed the association between intimate partner violence (IPV) perpetration and sexual risk behaviors and fatherhood (having fathered children) among young men. Methods. Sexually active men aged 18 to 35 years who visited an urban community health center and who reported having sexual intercourse with a steady female partner during the past 3 months (N = 283) completed a brief self-administered survey about sexual risk behaviors, IPV perpetration, and demographics. We conducted logistic regression analyses adjusted for demographics to assess associations between IPV and sexual risk behaviors and fatherhood. Results. Participants were predominantly Hispanic (74.9%) and Black (21.9%). Participants who reported IPV perpetration during the past year (41.3%) were significantly more likely to report (1) inconsistent or no condom use during vaginal and anal sexual intercourse, (2) forcing sexual intercourse without a condom, (3) having sexual intercourse with other women, and (4) having fathered 3 or more children. Conclusion. IPV perpetration was common among our sample and was associated with increased sexual risk behaviors. Urban community health centers may offer an important venue for reaching this at-risk population. PMID:16670216

Intimate Terrorism by Women Towards Men: Does it Exist?

PubMed Central

Hines, Denise A.; Douglas, Emily M.

2010-01-01

Research showing that women commit high rates of intimate partner violence (IPV) against men has been controversial because IPV is typically framed as caused by the patriarchal construction of society and men’s domination over women. Johnson’s (1995) typology of common couple violence (CCV) and intimate terrorism (IT) attempted to resolve this controversy, but he maintained that IT was caused by patriarchy and committed almost exclusively by men. This study investigates Johnson’s theory as it applies to a sample of 302 men who sustained IPV from their female partners and sought help, and a comparison sample of community men. Results showed that the male helpseekers sample was comprised of victims of IT and that violence by the male victims was part of a pattern of what Johnson labels violent resistance. Men in the community sample who were involved in IPV conformed to Johnson’s description of CCV. Results are discussed in terms of research, policy, and practice implications of acknowledging women’s use of severe IPV and controlling behavior against their male partners. PMID:21165167

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

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.

Homicide is one of the leading causes of death for women aged ≤44 years.* In 2015, homicide caused the death of 3,519 girls and women in the United States. Rates of female homicide vary by race/ethnicity (1), and nearly half of victims are killed by a current or former male intimate partner (2). To inform homicide and intimate partner violence (IPV) prevention efforts, CDC analyzed homicide data from the National Violent Death Reporting System (NVDRS) among 10,018 women aged ≥18 years in 18 states during 2003-2014. The frequency of homicide by race/ethnicity and precipitating circumstances of homicides associated with and without IPV were examined. Non-Hispanic black and American Indian/Alaska Native women experienced the highest rates of homicide (4.4 and 4.3 per 100,000 population, respectively). Over half of all homicides (55.3%) were IPV-related; 11.2% of victims of IPV-related homicide experienced some form of violence in the month preceding their deaths, and argument and jealousy were common precipitating circumstances. Targeted IPV prevention programs for populations at disproportionate risk and enhanced access to intervention services for persons experiencing IPV are needed to reduce homicides among women.

Husbands' alcohol use has been associated with family-level stress and intimate partner violence (IPV) against women in India. Joint family systems are common in India and IPV often co-occurs with non-violent family maltreatment of wives (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care). Alcohol use increases for some parents following the birth of a child. This study examined 1,038 postpartum women's reports of their husbands' alcohol use and their own experiences of IPV (by husband) and non-violent maltreatment from husbands and/or in-laws. We analyzed cross-sectional, quantitative data collected in 2008, from women (ages 15-35) seeking immunizations for their infants <6 months at three large urban health centers in Mumbai, India. Crude and adjusted logistic regression models estimated associations between the independent variable (husbands' past month use of alcohol) and two dependent variables (postpartum IPV and maltreatment). Overall, 15% of husbands used alcohol, ranging from daily drinkers (10%) to those who drank one to two times per week (54%). Prevalence of postpartum IPV and family maltreatment was 18% and 42%, respectively. Prevalence of IPV among women married to alcohol users was 27%. Most abused women's husbands always (27%) or sometimes (37%) drank during violent episodes. Risk for IPV increased with a man's increasing frequency of consumption. Women who lived with a husband who drank alcohol, relative to non-drinkers, were more likely to report postpartum IPV, aOR = 2.0, 95% confidence interval (CI) = [1.3, 3.1]. Husbands' drinking was marginally associated with increased risk for family maltreatment, aOR = 1.4, 95% CI = [1.0, 2.1]. Our findings suggest that men's alcohol use is an important risk factor for postpartum IPV and maltreatment. Targeted services for Indian women contending with these issues are implicated. Postpartum care offers an ideal opportunity to screen for IPV, household maltreatment, and other health risks, such as husband's use of alcohol. There is need to scale up proven successful interventions for reducing men's alcohol use and design strategies that provide at-risk women protection from alcohol-related IPV.

To identify characteristics that facilitate trust in the patient-provider relationship among survivors of intimate partner violence (IPV). Semistructured, open-ended interviews were conducted to elicit participants' beliefs and attitudes about trust in interactions with health care providers. Using grounded theory methods, the transcripts were analyzed for common themes. A community advisory group, composed of advocates, counselors and IPV survivors, helped interpret themes and interview excerpts. Together, key components of trust were identified. Eastern Massachusetts. Twenty-seven female survivors of IPV recruited from community-based IPV organizations. Participants' ages ranged from 18 to 56 years, 36% were African American, 32% Hispanic, and 18% white. We identified 5 dimensions of provider behavior that were uniquely important to the development of trust for these IPV survivors: 1) communication about abuse: provider was willing to openly discuss abuse; 2) professional competency: provider asked about abuse when appropriate and was familiar with medical and social histories; 3) practice style: provider was consistently accessible, respected confidentiality, and shared decision making; 4) caring: provider demonstrated personal concern beyond biomedical role through nonjudgmental and compassionate gestures, empowering statements, and persistent, committed behaviors; 5) emotional equality: provider shared personal information and feelings and was perceived by the participant as a friend. These IPV survivors identified dimensions of provider behavior that facilitate trust in their clinical relationship. Strengthening these provider behaviors may increase trust with patients and thus improve disclosure of and referral for IPV.

Mental ill health in structural pathways to women's experiences of intimate partner violence.

Depression, post-traumatic stress disorder (PTSD), and binge drinking are among mental health effects of child abuse and intimate partner violence (IPV) experiences among women. Emerging data show the potential mediating role of mental ill health in the relationship of child abuse and IPV. There is evidence that PTSD, depression and alcohol abuse are comorbid common mental disorders and that a bidirectional relationship exists between depression and IPV in some settings. Furthermore, the temporal direction in the relationship of alcohol abuse and women's IPV experiences from different studies is unclear. We undertook a study with women from the general population to investigate the associations of child abuse, mental ill health and IPV; and describe the underlying pathways between them. Data is from a household survey employing a multi-stage random sampling approach with 511 women from Gauteng, South Africa. IPV was measured using the WHO Multi-country Study on Women's Health and Domestic Violence Questionnaire. Child abuse was measured using a short form of the Childhood Trauma Questionnaire. Depression was measured using the Centre for Epidemiologic Studies Depression Scale (CESD). PTSD symptoms were measured using the Harvard Trauma Questionnaire. Binge drinking was measured using the Alcohol Use Disorders Identification Test (AUDIT) scale. All data analyses were conducted in Stata 13. Regression modelling was used to test the association between variables. Structural equation modelling with full information maximum likelihood estimation accounting for missing data was done to analyse the underlying pathways between variables. Fifty percent of women experienced IPV in their lifetime and 18% experienced IPV in the 12 months before the survey. Twenty three percent of women were depressed, 14% binge drank and 11.6% had PTSD symptoms. Eighty six percent of women had experienced some form of child abuse. Sociodemographic factors associated with recent IPV in multivariate models were younger age and foreign nationality. Depression, PTSD and binge drinking mediated the relationship of child abuse and recent IPV. Depression, PTSD and binge drinking were also effects of recent IPV. Other factors associated with recent IPV experience included relationship control, having a partner who regularly consumed alcohol and experiencing other life traumatic experiences. Mental ill health plays a mediating role in the relationship of child abuse and recent IPV experiences among women. Conversely, IPV also negatively affects women's mental health. Interventions to reducing the incidence of IPV could help alleviate the burden of mental ill health among women and vice versa. Effective integration of mental health services in primary health care, detection of symptoms, brief interventions and strengthened referral mechanisms for sustained community-based care are necessary in responding to victims of intimate partner violence. Response for abused children needs to take similar approaches and reduce the long-term mental health effects associated with violent exposures.

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.

This paper presents the findings from a community based participatory research (CBPR) study that investigated the interface between culture and intimate partner violence (IPV) for women in selected cultural groups in Hawaii: Native Hawaiian, Filipino, Samoan, and Chuukese. The research question was, “What are the cultural perceptions, responses, and needs regarding IPV of selected individuals and groups served through a variety of programs that are affiliated with the three participating Community Health Centers (CHCs)?” This cross sectional, descriptive study collected both qualitative and quantitative data. Individual interviews were conducted with women who had experienced IPV. Focus groups were also conducted with other women from the same culture. Five common themes were identified across the four cultural groups: Living within a Collective; Cultural Protective Factors; Cultural Barriers to Helpseeking; Gender Specific Roles; and Belonging to a Place. The outcome from this study is increased knowledge that will be used to develop culturally appropriate interventions. Specific findings from each cultural group have been published.1–4 The purpose of this paper is to present common perceptions and responses to IPV from the four groups and suggest interventions based on the findings. Implications for practice are presented. PMID:21225589

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.

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

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.

Background Exposure to armed conflict and/or war have been linked to an increase in intimate partner violence (IPV) against women. A substantial body of work has focused on non-partner rape and sexual violence in war and post-war contexts, but research about IPV is limited, particularly in Asian settings. This paper presents the finding of a study conducted in the Eastern Province of Sri Lanka. The study explored women’s experiences of and responses to IPV as well as how health and social service providers perceive the problem. It also explored the IPV-related services and supports available after the end of a 30-year civil war. Method We conducted in-depth, qualitative interviews with 15 women who had experienced IPV and 15 service providers who were knowledgeable about IPV in the Eastern Province of Sri Lanka. Interviews were translated into English, coded and organized using NVivo8, and analyzed using inductive thematic analysis. Results Participants described IPV as a widespread but hidden problem. Women had experienced various forms of abusive and controlling behaviours, some of which reflect the reality of living in the post-war context. The psychological effects of IPV were common, but were often attributed to war-related trauma. Some men used violence to control women and to reinstate power when their gender roles were reversed or challenged due to war and post-war changes in livelihoods. While some service providers perceived an increase in awareness about IPV and more services to address it, this was discordant with women’s fears, feelings of oppression, and perception of a lack of redress from IPV within a highly militarized and ethnically-polarized society. Most women did not consider leaving an abusive relationship to be an option, due to realistic fears about their vulnerability to community violence, the widespread social norms that would cast them as outsiders, and the limited availability of related services and supports. Implications These findings revealed the need for more research about IPV in post-war contexts. Women’s experiences in such contexts are influenced and may be masked by a complex set of factors that intersect to produce IPV and entrap women in violence. A more nuanced understanding of the context-specific issues that shape women’s experiences of IPV- and community responses to it—is needed to develop more comprehensive solutions that are relevant to the local context.

To describe the occurrence, dynamics and predictors of intimate partner violence (IPV) during pregnancy, including links with HIV, in urban Zimbabwe. A cross-sectional survey of 2042 post-natal women aged 15-49 years was conducted in six public primary healthcare clinics in low-income urban Zimbabwe. An adapted WHO questionnaire was used to measure IPV. Multivariate logistic regression was used to assess factors associated with IPV and severe (six or more episodes) IPV during pregnancy. 63.1% of respondents reported physical, emotional and/or sexual IPV during pregnancy: 46.2% reported physical and/or sexual violence, 38.9% sexual violence, 15.9% physical violence and 10% reported severe violence during pregnancy. Physical violence was less common during pregnancy than during the last 12 months before pregnancy (15.9% [95% CI 14.3-17.5] vs. 21.3% [95% confidence interval 19.5-23.1]). Reported rates of emotional (40.3% [95% CI 38.1-42.3] vs. 44.0% [95% CI 41.8-46.1]) and sexual violence (35.6% [95% CI 33.5-37.7] vs. 38.9% [95% CI 36.8-41.0]) were high during and before pregnancy. Associated factors were having a younger male partner, gender inequities, past abuse, problem drinking, partner control of woman's reproductive health and risky sexual practices. HIV status was not associated with either IPV or severe IPV, but reporting a partner with a known HIV status was associated with a lower likelihood of severe abuse. The rates of IPV during pregnancy in Zimbabwe are among the highest ever reported globally. Primary prevention of violence during childhood through adolescence is urgently needed. Antenatal care may provide an opportunity for secondary prevention but this requires further work. The relationship between IPV and HIV is complex in contexts where both are endemic. © 2013 John Wiley & Sons Ltd.

Intimate partner violence (IPV), an actual or threatened physical, sexual, or psychological abuse by a current or former partner or spouse, is a common global public health issue. Understanding both the prevalence of IPV during pregnancy and its potential impact on the health of pregnant women is important for the development and implementation of interventions to prevent maternal morbidity and mortality. The purpose of this study was to explore the association between maternal experiences of IPV during pregnancy and pregnancy complications. A health-facility-based cross-sectional study was conducted from July 2015 to April 2016 among 400 randomly selected women who were admitted to the postnatal wards of Rajshahi Medical College Hospital for delivery. Data were collected through face-to-face interviews using a structured questionnaire. Multivariable logistic regressions were performed to assess relationships between variables of interest after controlling for potential confounders. Results indicated that 39.0% of women reported physical IPV and 26.3% of women reported sexual IPV during pregnancy. Additionally, 69.5% of women experienced medical complications (MCs); of this group, 44.3% experienced obstetric complications (OCs) and 79.3% experienced any pregnancy complication (AC) during their last pregnancy. The experience of physical IPV during pregnancy was significantly associated with the experience of MCs (adjusted odds ratio (AOR): 2.05, 95% confidence interval (CI): 1.15-4.01), OCs (AOR: 4.23, 95% CI: 2.01-7.12) and AC (AOR: 5.26, 95% CI: 2.98-10.52). Women who experienced sexual IPV during pregnancy were also at increased risk of suffering from any MC, any OC, and AC. Maternal experience of IPV during pregnancy is positively associated with pregnancy complications. Preventing IPV directed at pregnant women might reduce maternal morbidity and mortality in Bangladesh. © 2018 Wiley Periodicals, Inc.

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.

Background Intimate partner violence (IPV) is the most common form of violence against women worldwide. IPV during pregnancy is an important risk factor for adverse health outcomes for women and their offspring. However, the prevalence of IPV during pregnancy is not well understood in China. The objective of this study was to estimate the pooled prevalence of IPV during pregnancy in China using a systematic review and meta-analysis. Methods Systematic literature searches were conducted in PubMed, Web of Science, CNKI, Wanfang, Weipu and CBM databases to identify relevant articles published from the inception of each database to January 31, 2016 that reported data on the prevalence of IPV during pregnancy in China. The Risk of Bias Tool for prevalence studies was used to assess the risk of bias in individual studies. Owing to significant between-study heterogeneity, a random-effects model was used to calculate the pooled prevalence and corresponding 95% confidence interval, and then univariate meta-regression analyses were performed to investigate the sources of heterogeneity. Subgroup analysis was conducted to explore the risk factors associated with IPV during pregnancy. Results Thirteen studies with a total of 30,665 individuals were included in this study. The overall pooled prevalence of IPV during pregnancy was 7.7% (95% CI: 5.6–10.1%) with significant heterogeneity (I2 = 97.8%, p < 0.001). The results of the univariate meta-regression analyses showed that only the variable “sample source” explained part of the heterogeneity in this study (p < 0.05). The characteristics “number of children” and “unplanned pregnancy” were determined as risk factors for experiencing violence during pregnancy. Conclusions The prevalence of IPV during pregnancy in China is considerable and one of the highest reported in Asia, which suggests that issues of violence against women during pregnancy should be included in efforts to improve the health of pregnant women and their offspring. In addition, a nationwide epidemiological study is needed to confirm the prevalence estimates and identify more risk factors for IPV during pregnancy. PMID:28968397

Introduction Prevention of mother-to-child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts of sub-Saharan Africa, PMTCT coverage remains low, leading to unacceptably high rates of morbidity among mothers and new infections among infants. Intimate partner violence (IPV) may be a structural driver of poor PMTCT uptake, but has received little attention in the literature to date. Methods We conducted qualitative research in three Johannesburg antenatal clinics to understand the links between IPV and HIV-related health of pregnant women. We held focus group discussions with pregnant women (n=13) alongside qualitative interviews with health care providers (n=10), district health managers (n=10) and pregnant abused women (n=5). Data were analysed in Nvivo10 using a team-based approach to thematic coding. Findings We found qualitative evidence of strong bidirectional links between IPV and HIV among pregnant women. HIV diagnosis during pregnancy, and subsequent partner disclosure, were noted as a common trigger of IPV. Disclosure leads to violence because it causes relationship conflict, usually related to perceived infidelity and the notion that women are “bringing” the disease into the relationship. IPV worsened HIV-related health through poor PMTCT adherence, since taking medication or accessing health services might unintentionally alert male partners of the women's HIV status. IPV also impacted on HIV-related health via mental health, as women described feeling depressed and anxious due to the violence. IPV led to secondary HIV risk as women experienced forced sex, often with little power to negotiate condom use. Pregnant women described staying silent about condom negotiation in order to stay physically safe during pregnancy. Conclusions IPV is a crucial issue in the lives of pregnant women and has bidirectional links with HIV-related health. IPV may worsen access to PMTCT and secondary prevention behaviours, thereby posing a risk of secondary transmission. IPV should be urgently addressed in antenatal care settings to improve uptake of PMTCT and ensure that goals of maternal and child health are met in sub-Saharan African settings. PMID:25371218

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

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.

There has been an ongoing debate about the extent and nature of gender differences in the experience of intimate partner violence (IPV). Disagreement about the appropriate definition of IPV is central to this debate. This study used latent class analysis (LCA) to map the patterns of physical violence, sexual coercion, psychological abuse and controlling behaviour, and examined whether LCA can better illuminate the gendered nature of this experience than conventional measures of IPV. Data from the 2004 Canadian General Social Survey were analysed, which included 8360 women and 7056 men 15 years of age and over who reported a current or ex-spouse or common-law partner. Results revealed more variation in the patterns of IPV for women than for men. Six classes were found for women, whereas four classes were found for men. Women and men were equally likely to experience less severe acts of physical aggression that were not embedded in a pattern of control. However, only women experienced a severe and chronic pattern of violence and control involving high levels of fear and injury. For women and men, intermediate patterns of violence and control, and patterns describing exclusively non-physical acts of abuse were also found. The results also revealed substantial differences in the IPV subtypes for those reporting about a current versus an ex-partner. These results support the use of LCA in identifying meaningful patterns of IPV and provide a more nuanced understanding of the role of gender than conventional measures. Implications for sampling within IPV research are discussed.

Intimate partner violence (IPV), which describes physical and/or sexual assault of a spouse or sexually intimate companion, is a common health care issue across the globe. However, existing health outcomes studies are limited. Additionally, no study to our knowledge has specifically focused on the relationship between IPV and sexual health among Latina immigrants in southwestern United States. Through the use of photovoice methodology and a community-based participatory research approach, we assessed these types of relationships drawing on data gathered from 22 Latina survivors of IPV and 20 community stakeholders in El Paso, Texas. Participants identified two major themes: the different expressions of domestic violence and the need for access to sexual and reproductive health services. Community stakeholders and participants identified practical and achievable recommendations and actions including the development of a promotora training program on IPV and sexual health. This assessment extends beyond HIV and STI risk behaviors and highlights disease prevention within a wellness and health promotion framework. PMID:24787021

Women who inject drugs (WWID) are an especially vulnerable group of drug users. This study determined the prevalence of psychiatric comorbidity and intimate partrner violence (IPV), and factors associated with psychiatric comorbidity among WWID recruited from drug treatment services (67%) and harm reduction services in five European regions in Austria, Catalonia, Italy, Poland, and Scotland. Psychiatric comorbidity was assessed among 226 WWID using the Dual Diagnosis Screening Instrument. IPV was assessed using the Composite Abuse Scale and injecting and sexual risk behaviors were assessed using a battery of questionnaires adapted and developed for the study. Eighty-seven percent met criteria for at least one lifetime psychiatric disorder. The most common disorders were depression (76%), panic (54%), and post-traumatic stress (52%). WWID recruited in drug treatment services were almost three times as likely (OR 2.90 95% CI 1.30-6.43; p = 0.007) to meet criteria for a lifetime psychiatric disorder than those recruited from harm reduction services, specifically dysthymia (OR 5.32 95% CI 2.27-12.48; p = 0.000) and post-traumatic stress disorder (OR 1.83 95% CI 1.02-3.27; p = 0.040). WWID who reported sharing needles and syringes were almost three times as likely to meet criteria for lifetime psychiatric comorbidity than those who did not (OR 2.65 95% CI 1.07-6.56). Compared to WWID who had not experienced IPV, victims (70%) were almost two times more likely to meet criteria for post-traumatic stress disorder (OR 1.95 95% CI 1.10-3.48). Psychiatric comorbidity and IPV among WWID are common. Drug treatment and harm reduction services should address psychiatric comorbidity and IPV to improve treatment outcomes.

Intimate partner violence (IPV) is one of the most common causes of posttraumatic stress disorder (PTSD) in women. Women with IPV-related PTSD often experience comorbid chronic pain and pain-related disability. Despite the high comorbidity between PTSD and chronic pain, recent evidence suggests that male veterans with combat-related PTSD report decreased sensitivity to experimental pain. The aim of this study was to examine the neurobehavioral correlates of experimental pain in women with IPV-related PTSD. Functional magnetic resonance neuroimaging data were collected during an event-related experimental pain paradigm that was administered twice to 23 women with IPV-related PTSD and 15 age-, race- and education-comparable nontraumatized control women. Brief thermal heat stimuli were repeatedly applied to the left volar forearm, and subjects rated the perceived temperature intensity with a button-box. Women with IPV-related PTSD relative to nontraumatized control women showed: 1) increased activation of right middle insula and right dorsolateral prefrontal cortex during initial painful stimulation, and 2) subsequent decrease in subjective intensity ratings with repeated exposure to pain, which was accompanied by attenuation of activation within right anterior insula that was associated with avoidance symptoms of PTSD. These results suggest that women with IPV-related PTSD show dysregulated functional brain activity during pain processing, which might drive maladaptive coping mechanisms, such as avoidance and numbing.

We address questions about (1) how college women with a disability experience sexual violence (SV) and intimate partner violence (IPV) across partners, including disability-specific abuse and (2) how SV/IPV impacts psychological, behavioral, physical, and academic life domains. Twenty-seven female college students (mean age, 21.2; 66.6% white; 66.6% heterosexual) were randomly sampled from university registrar records. To be eligible for the study, students had to have at least one experience of SV/IPV since age 18 and a disability (88.8% reported one or more mental health conditions; 11.1% reported other conditions, such as attention deficit and hyperactivity disorder; with the majority of women indicating their disability preceded SV/IPV victimization). Using the Centers for Disease Control and Prevention's definitions of SV/IPV as guides, clinically trained master's level interviewers conducted semistructured interviews to ascertain SV/IPV patterns across students' three most recent relationships and related life impacts. SV/IPV was pervasive in college women with a disability, within hookup settings and/or recurring SV/IPV with a long-term partner. For some women, SV spanned multiple abusive partners. For women in relationships marked by chronic abuse, in addition to SV, the relationship dynamic included disability-specific abuse, social isolation, threats/intimidation, and technology-related abuse. For women experiencing SV events within hookup settings, alcohol was a common facilitator, with some abusers using a disability to manipulate a sexual connection. All but one participant reported exacerbated adverse mental health consequences (e.g., depression, anxiety, post-traumatic stress disorder, suicidal ideation/attempts, stress) after victimization. These adverse mental health consequences coincided with adverse behavioral (e.g., becoming less social, avoiding usual study lounge areas on campus), physical (e.g., problems sleeping, bruising, pregnancy concerns, and sexually transmitted disease), and academic outcomes (e.g., skipping and/or dropping class, grades suffering). Our results underscore the need for continued investment in campus programs that improve response to SV/IPV, including prevention programs and support services tailored to the specific needs and vulnerabilities of women with underlying mental health conditions.

The study reviews recent publications on methamphetamine use and dependence women in term of their epidemic, physical health impact, psychosocial impacts, and also in the identified vulnerable issues. Studies of vulnerable populations of women are wide ranging and include sex workers, sexual minorities, homeless, psychiatric patients, suburban women, and pregnant women, in which amphetamine type stimulants (ATSs) are the most commonly reported illicit drug used among them. The prenatal exposure of ATS demonstrated the small for gestational age and low birth weight; however, more research is needed on long-term studies of methamphetamine-exposed children. Intimate partner violence (IPV) is commonly reported by female methamphetamine users as perpetrators and victims. However, statistics and gendered power dynamics suggest that methamphetamine-related IPV indicates a higher chance of femicide. Methamphetamine-abusing women often have unresolved childhood trauma and are introduced to ATS through families or partners. Vulnerable populations of women at risk of methamphetamine abuse and dependence. Impacts on their physical and mental health, IPV, and pregnancy have been reported continuing, which guide that empowering and holistic substance abuse are necessary for specific group.

Advanced Dependent Pressure Vessel (DPV) nickel-hydrogen spacecraft cell and battery design

Coates, Dwaine; Wright, Doug; Repplinger, Ron

1995-01-01

The dependent pressure vessel (DPV) nickel-hydrogen (NiH2) battery is being developed as a potential spacecraft battery design for both military and commercial satellites. Individual pressure vessel (IPV) NiH2 batteries are currently flying on more than 70 Earth orbital satellites and have accumulated more than 140,000,000 cell-hours in actual spacecraft operation. The limitations of standard NiH2 IPV flight battery technology are primarily related to the internal cell design and the battery packaging issues associated with grouping multiple cylindrical cells. The DPV cell design offers higher specific energy and reduced cost, while retaining the established IPV NiH2 technology flight heritage and database. The advanced cell design offers a more efficient mechanical, electrical and thermal cell configuration and a reduced parts count. The internal electrode stack is a prismatic flat-plate arrangement. The flat individual cell pressure vessel provides a maximum direct thermal path for removing heat from the electrode stack. The cell geometry also minimizes multiple-cell battery packaging constraints by using an established end-plateltie-rod battery design. A major design advantage is that the battery support structure is efficiently required to restrain only the force applied to a portion of the end cell. As the cells are stacked in series to achieve the desired system voltage, this increment of the total battery weight becomes small. The geometry of the DPV cell promotes compact, minimum volume packaging and places all cell terminals along the length of the battery. The resulting ability to minimize intercell wiring offers additional design simplicity and significant weight savings. The DPV battery design offers significant cost and weight savings advantages while providing minimal design risks. Cell and battery level design issues will be addressed including mechanical, electrical and thermal design aspects. A design performance analysis will be presented at both the cell and battery level. The DPV is capable of delivering up to 76 Watt-hours per kilogram (Wh/kg) at the cell level and 70 Wh/kg at the full battery level. This represents a 40 percent increase in specific energy at the cell level and a 60 percent increase in specific energy at the battery level compared to current IPV NiH2 technology.

Intimate partner violence (IPV) is the leading cause of non-fatal injury to women worldwide. Musculoskeletal injuries, which are often seen by orthopaedic surgeons, are the second most common manifestation of IPV. We aimed to establish the 12-month and lifetime prevalence of IPV in women presenting to orthopaedic fracture clinics. The PRAISE team of 80 investigators did a cross-sectional study of a consecutive sample of 2945 female participants at 12 orthopaedic fracture clinics in Canada, the USA, the Netherlands, Denmark, and India. Participants who met the eligibility criteria anonymously answered direct questions about physical, emotional, and sexual IPV, and completed two previously developed questionnaires (Women Abuse Screening Tool [WAST] and Partner Violence Screen [PVS]). We did a multivariable logistic regression analysis to investigate the risk factors associated with IPV. The overall response rate was 85% (2344 of 2759 patients provided informed consent). One in six women (455/2839, 16·0%, 95% CI 14·7-17·4%) disclosed a history of IPV within the past year, and one in three (882/2550, 34·6%, 32·8-36·5%) had experienced IPV in their lifetime. 49 women (1·7%, 1·3-2·2%) attended their clinic visit as a direct consequence of IPV, only seven of whom (14%) had ever been asked about IPV in a health-care setting. Women in short-term relationships (OR 0·584, 99% CI 0·396-0·860, p=0·0001) were at increased risk of IPV and physical abuse in the past 12 months in this study. Compared with women in Canada and the USA, those in the Netherlands and Denmark were at reduced risk of any abuse in the past 12 months, physical abuse in lifetime, and any abuse in lifetime (OR 0·595, 99% CI 0·427-0·830, p<0·0001; 0·630, 0·445-0·890, p=0·001; and 0·464, 0·352-0·612, p<0·0001, respectively). PRAISE is the largest prevalence study done so far in orthopaedics. Orthopaedic surgeons should be confident in the assumption that one in six women have a history of physical abuse, and that one in 50 injured women will present to the clinic as a direct result of IPV. Our findings warrant serious consideration for fracture clinics to improve identification of, respond to, and provide referral services for, victims of IPV.

To assess the prevalence and risk factors for intimate-partner violence (IPV) in women who attended a Family Medicine Unit in Tijuana, Mexico. A total of 297 women were interviewed and evaluated using two validated scales: violence and severity index and family APGAR to assess family functioning and IPV respectively. The mean age (± SD) was 40.6±13.8 years, and 120 (40.4%) women had suffered IPV: 47 (15.8%) psychological violence; 31 (10.4%) sexual violence; 77 (25.9%) physical violence, and in 19 (6.4%) there were actions that threatened the lives of women. The most common causes of domestic violence were women who reported that their partner had been jealous, or suspicion from friends (37.4%). Twenty two (7.4%) of the women with domestic violence reported that they had sought help. The prevalence of IPV was high and associated with the education level of the couple and family functioning.

Cruelty toward companion animals is a well-documented, coercive tactic used by abusive partners to intimidate and control their intimate partners. Experiences of co-occurring violence are common for children living in families with intimate partner violence (IPV) and surveys show that more than half are also exposed to abuse of their pets. Given children's relationships with their pets, witnessing such abuse may be traumatic for them. Yet little is known about the prevalence and significance of this issue for children. The present study examines the experiences of children in families with co-occurring pet abuse and IPV. Using qualitative methods, 58 children ages 7-12 who were exposed to IPV were asked to describe their experiences of threats to and harm of their companion animals. Following the interviews, template analysis was employed to systematically develop codes and themes. Coding reliability was assessed using Randolph's free-marginal multirater kappa (kfree=.90). Five themes emerged from the qualitative data, the most common being children's exposure to pet abuse as a power and control tactic against their mother in the context of IPV. Other themes were animal maltreatment to discipline or punish the pet, animal cruelty by a sibling, children intervening to prevent pet abuse, and children intervening to protect the pet during a violent episode. Results indicate that children's experiences of pet abuse are multifaceted, potentially traumatic, and may involve multiple family members with diverse motives. Copyright © 2015 Elsevier Ltd.

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.

Heru, Alison M.; Stuart, Gregory L.; Recupero, Patricia Ryan

2007-01-01

Background: Intimate partner violence (IPV) is commonly bidirectional with both partners perpetrating and being victims of aggressive behaviors. In these couples, family dysfunction is reported across a broad range of family functions: communication, intimacy, problem solving, expression or control of anger, and designation of relationship roles. This study reports on the perceived family functioning of suicidal inpatients. Method: In this descriptive, cross-sectional study of adult suicidal inpatients, participants completed assessments of recent IPV and family functioning. Recruited patients were between 18 and 65 years of age and English fluent, had suicidal ideation, and were living with an intimate partner for at least the past 6 months. Intimate partner violence was assessed using the Conflict Tactics Scale-Revised, and family functioning was measured using the McMaster Family Assessment Device. The study was conducted from August 2004 through February 2005. Results: In 110 inpatients with suicidal ideation and IPV, family functioning was perceived as poor across many domains, although patients did report family strengths. Gender differences were not found in the overall prevalence of IPV, but when the sample was divided into good and poor family functioning, women with poorer family functioning reported more psychological abuse by a partner. For both genders, physical and psychological victimization was associated with poorer family functioning. Conclusion: Among psychiatric inpatients with suicidal ideation, IPV occurred in relationships characterized by general dysfunction. Poorer general family functioning was associated with the perception of victimization for both genders. The high prevalence of bidirectional IPV highlights the need for the development of couples treatment for this population of suicidal psychiatric inpatients. PMID:18185819

There is little evidence about family planning knowledge, attitudes, and use among couples in post-conflict Democratic Republic of the Congo. We used qualitative descriptions to analyze data from 75 participants. Intimate partner violence (IPV) was common among participants. They were aware of family planning methods; however, IPV and fears of side effects were barriers to use. Although participants were concerned about the cost of large families, had positive attitudes toward family planning, and intended to use it, actual use was uncommon. The need for family planning was acute because of war-related poverty. Couples negotiated, but men had strong influence over family planning decisions. Couples saw health workers as a valuable resource. Interventions in this setting should include a couple-based approach that addresses IPV as well as family planning content.

Intimate partner violence (IPV) against women is a serious public health issue and is associated with significant adverse health outcomes. The current study was undertaken to: 1) explore physicians' and nurses' experiences, both professional and personal, when asking about IPV; 2) determine the variations by discipline; and 3) identify implications for practice, workplace policy and curriculum development. Physicians and nurses working in Ontario, Canada were randomly selected from recognized discipline-specific professional directories to complete a 43-item mailed survey about IPV, which included two open-ended questions about barriers and facilitators to asking about IPV. Text from the open-ended questions was transcribed and analyzed using inductive content analysis. In addition, frequencies were calculated for commonly described categories and the Fisher's Exact Test was performed to determine statistical significance when examining nurse/physician differences. Of the 931 respondents who completed the survey, 769 (527 nurses, 238 physicians, four whose discipline was not stated) provided written responses to the open-ended questions. Overall, the top barriers to asking about IPV were lack of time, behaviours attributed to women living with abuse, lack of training, language/cultural practices and partner presence. The most frequently reported facilitators were training, community resources and professional tools/protocols/policies. The need for additional training was a concern described by both groups, yet more so by nurses. There were statistically significant differences between nurses and physicians regarding both barriers and facilitators, most likely related to differences in role expectations and work environments. This research provides new insights into the complexities of IPV inquiry and the inter-relationships among barriers and facilitators faced by physicians and nurses. The experiences of these nurses and physicians suggest that more supports (e.g., supportive work environments, training, mentors, consultations, community resources, etc.) are needed by practitioners. These findings reflect the results of previous research yet offer perspectives on why barriers persist. Multifaceted and intersectoral approaches that address individual, interpersonal, workplace and systemic issues faced by nurses and physicians when inquiring about IPV are required. Comprehensive frameworks are needed to further explore the many issues associated with IPV inquiry and the interplay across these issues.

Background/Objectives Adolescent and young adult women are at high risk for both STI/HIV and intimate partner violence (IPV). We evaluate the prevalence of IPV in the past three months and its associations with STI/HIV risk, STI, and related care-seeking over the same time period. Methods Female family planning clinic patients ages 16–29 (n=3,504) participated in a cross-sectional survey in 2011–2012 as a baseline assessment for an intervention study. We examined associations of recent IPV with sexual and drug-related STI/HIV risk behavior, self-reported STI, and STI-related clinical care seeking via logistic regression. Results Recent physical or sexual IPV (prevalence 11%) was associated with recent sexual and drug-related STI/HIV risk, specifically unprotected vaginal sex (AOR 1.93, 95% CI 1.52, 2.44), unprotected anal sex (AOR 2.22, 95% CI 1.51, 3.27) and injection drug use, both their own (AOR 3.39, 95% CI 1.47, 7.79) and their partner’s (AOR 3.85, 1.91, 7.75). IPV was also linked with coercive sexual risk: involuntary condom non-use (AOR 1.87, 95% CI 1.51, 2.33), and fears of requesting condoms (AOR 4.15, 95% CI 2.73, 6.30) and refusing sex (AOR 11.84, 95% CI 7.59, 18.45). STI-related care-seeking was also more common among those abused (AOR 2.49, 95% CI 1.87, 3.31). Conclusions Recent IPV is concurrent with sexual and drug-related STI/HIV risk, including coercive sexual risk, thus compromising women’s agency in STI/HIV risk reduction. Clinical risk assessments should broaden to include unprotected heterosexual anal sex, coercive sexual risk, and IPV, and should promote safety and harm reduction. PMID:24234072

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.

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.

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.

Anger, Control, and Intimate Partner Violence in Young Adulthood

PubMed Central

Giordano, Peggy C.; Copp, Jennifer E.; Longmore, Monica A.; Manning, Wendy D.

2015-01-01

A common theme in the literature is that intimate partner violence (IPV) is not about anger, but about power and control. While prior research has focused either on respondents' or partners' controlling behaviors, an interactionist perspective provides the basis for hypothesizing that both respondent and partner control will be significantly related to the odds of reporting perpetration, and that emotional processes are a component of IPV experiences. Analyses rely on interview data collected at waves 1 and 5 of a longitudinal study (Toledo Adolescent Relationships Study; n = 928) of adolescent and young adult relationships. Results indicate that after controlling for traditional predictors, both respondent and partner control attempts and measures of anger (including a measure of relationship-based anger) contributed significantly to the odds of reporting perpetration. Further, these patterns did not differ by gender, indicating some areas of similarity in the relationship and emotional processes associated with variations in men and women's IPV reports.

This study was aimed to estimate the prevalence of intimate partner violence (IPV) in a sample of 226 women with disabilities living in four different districts of Bangladesh. It also explored the physical and psychological suffering of women experiencing violence and their various coping strategies. A cross-sectional survey was carried out with 226 women with disabilities to measure the prevalence of IPV, and 16 in-depth interviews were conducted to document in detail the experiences of violence encountered by the abused women. Among the 226 women interviewed in the survey, about 84% reported ever having experienced at least one act of emotional abuse, physical, or sexual violence from their partner during their lifetime. Women who were older (aged above 32 years), separated, and members of economic/savings group were more likely to report ever having experienced any IPV than women with disabilities who were younger (aged 32 years and less), married, and not members of economic/savings group. Most of the women experiencing violence reported sufferings from physical and psychological problems. Of all the women who experienced violence, less than half (45%) reported seeking support to minimize or avoid violence experiences. However, seeking support from informal network such as family and relatives was commonly reported by many (81.4%) of them. Study findings suggest that women with disabilities who possess poor socio-economic status coupled with economic dependency on husbands' income and wide-spread social stigma against disability make them vulnerable to IPV. Future interventions to address IPV against women with disabilities should include building community knowledge of disability and IPV, countering the pervasive social stigma against disabilities, and improving the socio-economic conditions of women with disabilities through education and employment. © The Author(s) 2014.

Developing and Validating the Scale of Economic Self-Efficacy.

Hoge, Gretchen L; Stylianou, Amanda M; Hetling, Andrea; Postmus, Judy L

Experiencing intimate partner violence (IPV) and financial hardship are often intertwined. The dynamics of an abusive relationship may include economic abuse tactics that compromise a survivor's ability to work, pursue education, have access to financial resources, and establish financial skills, knowledge, and security. An increasingly common goal among programs serving IPV survivors is increasing financial empowerment through financial literacy. However, providing financial education alone may not be enough to improve financial behaviors. Psychological factors also play a role when individuals make financial choices. Economic self-efficacy focuses on the individual's perceived ability to perform economic or financial tasks, and may be considered a primary influence on one's ability to improve financial decisions and behaviors. The current study tests the reliability and validity of a Scale of Economic Self-Efficacy with a sample of female survivors of IPV. This study uses a calibration and validation analysis model including full and split-sample exploratory and confirmatory factor analyses, assesses for internal consistency, and examines correlation coefficients between economic self-efficacy, economic self-sufficiency, financial strain, and difficulty living with income. Findings indicate that the 10-item, unidimensional Scale of Economic Self-Efficacy demonstrates strong reliability and validity among this sample of IPV survivors. An ability to understand economic self-efficacy could facilitate individualized service approaches and allow practitioners to better support IPV survivors on their journey toward financial empowerment. Given the increase in programs focused on assets, financial empowerment, and economic well-being, the Scale of Economic Self-Efficacy has potential as a very timely and relevant tool in the design, implementation, and evaluation of such programs, and specifically for programs created for IPV survivors.

This study examined patterns of violence victimization and aggression in both intimate partner and nonpartner relationships among U.S. military veterans using latent profile analysis to identify subtypes of violence involvement. Participants were 839 substance use treatment-seeking veterans (93% male) from a large Veterans Affairs Medical Center who completed screening measures for a randomized controlled trial. Past-year violence involvement, including both intimate partner violence (IPV) and nonpartner violence (NPV), was common in the sample, although NPV occurred at somewhat higher rates. When we included either IPV or NPV aggression or victimization, more than 40% reported involvement with physical violence, 30% with violence involving injury, and 86% with psychological aggression. Latent profile analysis including both aggression and victimization in partner and nonpartner relationships indicated a four-profile solution: no/low violence (NLV; n = 377), predominantly IPV (n = 219), predominantly NPV (n = 134), and high general violence (HGV; n = 109). Multinomial logistic regression analyses revealed that, compared with the NLV group, the remaining three groups differed in age, cocaine use, posttraumatic stress disorder (PTSD) symptoms, and legal involvement. Legal issues appeared to differentiate the profiles most, with the predominantly NPV and HGV profiles reporting more instances of driving under the influence and the HGV profile reporting legal problems related to aggression. IPV and NPV are fairly common among veterans seeking substance use treatment. The clinical characteristics of violence profiles indicate that cocaine use, PTSD symptoms, and legal involvement are treatment needs that vary with violence profile and may be useful for clinical decision making.

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.

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.

Women's perceptions of effects of war on intimate partner violence and gender roles in two post-conflict West African Countries: consequences and unexpected opportunities.

The aim of this paper is to explore women's perceptions of the causes of intimate partner violence (IPV) in West Africa, and the ways in which they understand these causes to interact with the experiences of war. The study was conducted in two locations in Sierra Leone and two in Liberia, using focus group discussions (N groups =14) and individual interviews (N = 20). Women perceive the causes of IPV to be linked with other difficulties faced by women in these settings, including their financial dependence on men, traditional gender expectations and social changes that took place during and after the wars in those countries. According to respondents, the wars increased the use of violence by some men, as violence became for them a normal way of responding to frustrations and challenges. However, the war also resulted in women becoming economically active, which was said by some to have decreased IPV, as the pressure on men to provide for their families reduced. Economic independence, together with services provided by NGOs, also gave women the option of leaving a violent relationship. IPV was found to be a significant problem for women in Sierra Leone and Liberia. The interactions between war experiences and financial and cultural issues are multi-faceted and not uniformly positive or negative.

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

Objectives. We assessed the relation of childhood sexual abuse (CSA), intimate partner violence (IPV), and depression to HIV sexual risk behaviors among Black men who have sex with men (MSM). Methods. Participants were 1522 Black MSM recruited from 6 US cities between July 2009 and December 2011. Univariate and multivariable logistic regression models were used. Results. Participants reported sex before age 12 years with someone at least 5 years older (31.1%), unwanted sex when aged 12 to 16 years (30%), IPV (51.8%), and depression (43.8%). Experiencing CSA when aged 12 to 16 years was inversely associated with any receptive condomless anal sex with a male partner (adjusted odds ratio [AOR] = 0.50; 95% confidence interval [CI] = 0.29, 0.86). Pressured or forced sex was positively associated with any receptive anal sex (AOR = 2.24; 95% CI = 1.57, 3.20). Experiencing CSA when younger than 12 years, physical abuse, emotional abuse, having been stalked, and pressured or forced sex were positively associated with having more than 3 male partners in the past 6 months. Among HIV-positive MSM (n = 337), CSA between ages 12 and 16 years was positively associated with having more than 3 male partners in the past 6 months. Conclusions. Rates of CSA, IPV, and depression were high, but associations with HIV sexual risk outcomes were modest. PMID:26469666

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.

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

PubMed

Stern, Erin; Niyibizi, Lea Liliane

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.

Premilitary intimate partner violence and attrition from the U.S. Navy.

A prospective study of U.S. Navy recruits (N = 5,498) examined whether premilitary intimate partner violence (IPV) was associated with attrition. Overall, more than one-fourth of recruits reported premilitary physical IPV and more than two-thirds reported premilitary verbal IPV. Women reported more perpetration and receipt of IPV than men, and married or cohabiting respondents reported more IPV than single respondents. Both perpetration and receipt of IPV significantly predicted attrition within 4 years. However, after controlling for other forms of IPV, only receipt of physical IPV significantly predicted attrition. In only one analysis did associations between IPV and attrition vary according to marital status or gender; premilitary receipt of verbal IPV had different effects on women and men.

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.

2005-04-01

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.

Vatnar, Solveig Karin Bø; Bjørkly, Stål

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.

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.

Inactivated poliovirus vaccine given alone or in a sequential schedule with bivalent oral poliovirus vaccine in Chilean infants: a randomised, controlled, open-label, phase 4, non-inferiority study.

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.

Testing posttraumatic stress as a mediator of physical, sexual, and psychological intimate partner violence and substance problems among women.

PubMed

Sullivan, Tami P; Cavanaugh, Courtenay E; Buckner, Julia D; Edmondson, Donald

2009-12-01

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.

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.

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.

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.

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) 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.

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.

The term "intimate partner violence" (IPV) encompasses physical, sexual and psychological violence, or any combination of these acts, and globally is the most common type of violence against women. This study aims to examine the lifetime prevalence of different types of intimate partner violence (IPV) among Malawi women ages 15 to 49, and its association with age, education, and living in rural versus urban areas. Data was obtained from a cross-sectional study of data as part of the 2004 Malawi Demographic and Health Survey. Women were eligible for the study if they met the following criteria: 1) lived in one of the 15,041 households randomly selected from 522 rural and urban clusters located in 10 large districts of Malawi; 2) were married or cohabitating; and 3) were between the ages of 15 and 49 years. Consenting, eligible women responded to a comprehensive questionnaire covering demographic factors, health issues, as well as items related to physical, emotional and sexual IPV. To assess bivariate associations, chi-squared tests and multivariate logistic regressions were conducted. Among the 8291 respondents, 13% reported emotional violence; 20% reported being pushed, shaken, slapped or punched; 3% reported experiencing severe violence, such as being strangled or burned, threatened with a knife, gun or with another weapon; and 13% reported sexual violence. Data showed women ages 15 to 19 were significantly less likely to report emotional IPV, women ages 25 to 29 were significantly more likely to report being pushed or shaken, slapped or punched (OR 1.35; CI: 1.05-1.73), and women ages 30 to 34 were significantly more likely to report sexual IPV, compared to women ages 45 to 49 (OR 1.40; CI: 1.03-1.90). Finally, women who had no ability to read were less likely to report sexual IPV than their counterparts who could read a full sentence (OR 0.76; CI: 0.66-0.87). The prevalence of different types of IPV in Malawi appears slightly lower than that reported for other countries in sub-Saharan Africa. Further studies are needed to assess the attitudes and behaviors of Malawi women towards acceptability and justification of IPV as well as their willingness to disclose it.

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.

Although academics are trained in research methods, few receive formal training in strategies for implementing equitable community engaged research. Academics and their community partners can benefit from such direction and assistance as they establish and maintain community-based participatory research (CBPR) partnerships. Research partners from the University of Pittsburgh, the Johns Hopkins Center for Injury Research and Policy, and the House of Ruth Maryland, one of the nation's leading domestic violence centers serving Baltimore and the surrounding areas, joined together to design, implement, and evaluate a series of activities to increase local CPBR capacity. This article provides an overview of process and findings from two CBPR workshops jointly held for academic and community members and explores specific suggestions from the workshop participants about how to put the CBPR principles into practice to promote community engaged research to address intimate partner violence (IPV). Twenty-four academic and community partners with experience addressing IPV participated in the two workshops. Facilitators led discussions based on the core CPBR principles. Participants were asked to interpret those principles, identify actions that could help to put the principles into practice, and discuss challenges related to CBPR approaches for IPV research. Observational notes and transcripts of the discussions and workshop evaluations are summarized. The CBPR principles were interpreted and revised through consensus into common language that reflected the group discussion of the core CBPR principles. Workshop participants provided a range of actions for putting the principles into practice and identified the need for sensitivity in relation to IPV research. A majority of participants felt that the workshop generated novel ideas about how they could use CPBR in their own work. Translating CBPR principles into common, action-oriented language is a useful first step when building a new academic-community research partnership.

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.

Sociocultural and Victimization Factors That Impact Attitudes Toward Intimate Partner Violence Among Kenyan Women.

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.

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.

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.

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.

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.

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.

In both China and the United States, public attitudes toward intimate partner violence (IPV) have shifted from viewing IPV as a tolerable, private matter to viewing it as a matter of public concern that should be dealt with as a crime. Empirical and comparative examinations of the perceptions of why women stay in physically abusive relationships are lacking. Answering this question calls for comprehensive, methodologically rigorous research. Using survey data collected from approximately 1,000 college students from two Chinese and two U.S. universities, this study empirically compared and contrasted factors that impact U.S. and Chinese students' perceptions as to why women remain in physically abusive relationships. Utilizing a theoretical framework of social constructionism, two common reasons were assessed: Women stay in physically abusive relationships because of learned helplessness and positive beliefs in the relationship/hope for the future. The results show that viewing IPV as a crime, gender, and beliefs of the causes of IPV were robust predictors of college students' perceptions toward why women stay in physically abusive relationships. U.S. college students were more likely to express sympathy and understanding toward why women remain in abusive relationships than Chinese students. Directions for future research and policy implications were discussed.

While intimate partner violence (IPV) and sexual violence (SV) are highly associated with injury, the healthcare and legal significance of these injuries is controversial. Purpose: Herein we propose to explore the significance of injury in IPV and SV and examine the current status of injury classification systems from the perspectives of the healthcare and criminal justice systems. We will review current injury classification systems and suggest a typology of injury that could be tested empirically. Findings: Within the published literature, we found that no commonly-accepted injury typology exists. While nuanced and controversial issues surround the role of injury detection in the sexual assault forensic examination, enough evidence exists to support the continued pursuance of a scientific approach to injury classification. We propose an injury typology that is measureable, is applicable to the healthcare setting and criminal justice system, and allows us to use uses a matrix approach that includes a severity score, anatomic location, and injury type. We suggest a typology that might be used for further empirical testing on the validity and reliability of IPV and SV injury data. Conclusion: We recommend that the community of scientists concerned about IPV and SV develop a more rigorous injury classification system that will improve the quality of forensic evidence proffered and decisions made throughout the criminal justice process.

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.

Objectives To estimate the prevalence of intimate partner violence (IPV) among a sample of rural Chinese women and to explore associated factors. Design Cross-sectional study. Setting Rural areas of Guangyuan City, Sichuan, China. Participants We recruited 1501 women, aged 16 years and older, who had been living locally for at least 2 years and reported being married or in a relationship during the past 12 months. They were among a sample of 1898 potential participants from our larger parent study on the prevalence of depressive-distress symptoms. Methods Participants completed demographic and social economic measures, the Short Form of the Revised Conflict Tactics Scale and the Duke Social Support Index. We applied χ2 test, analysis of variance and confirmatory factor analysis for analysis. Results The overall prevalence of IPV in the past 12 months was 29.05%; the prevalence of physical, psychological and sexual violence was 7.66%, 26.58% and 3.20%, respectively. The overall prevalence was highest among women aged 16–29 years, and was more common among those without a high school diploma and who saw their family’s financial status as very poor or stagnant. Women who were not victims of IPV had higher levels of social support. Confirmatory factor analysis showed that the total effects of social support on physical, psychological and sexual violence were −0.12, –0.35 and −0.12, respectively. The indirect effects of objective economic status on physical, psychological and sexual violence were −0.047, –0.014 and −0.047, respectively, but the total effect was not significant. The indirect effect of education on psychological violence was −0.056. Conclusion IPV is common in rural Guangyuan. Our data are comparable with the findings from north-west of China. Social support is an important protective factor. Future work is needed to develop, test and later disseminate potential IPV interventions, with a focus on building actual and perceived supportive social networks. PMID:29420233

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.

To assess the relationship between bullying peers as a child and adult intimate partner violence perpetration in a clinic-based sample of adult men. School bullying perpetration and intimate partner violence perpetration are both thought to stem from desire for power and control over others. A cross-sectional survey was conducted between January 2005 and December 2006. Three urban community health centers in Boston, Massachusetts. Men aged 18 to 35 years (n = 1491) seeking services at participating community health centers. School bullying perpetration. Past-year physical or sexual violence perpetration against a female partner (intimate-partner violence [IPV]). Two-fifths of men reported perpetrating school bullying as a child (n = 610; 40.9%). Men who rarely bullied in school were 1.53 times more likely to perpetrate past-year IPV than men who did not bully (95% confidence interval [CI], 1.02-2.29); this risk was elevated to 3.82 times more likely to perpetrate any past-year IPV for those men who bullied peers frequently (95% CI, 2.55-5.73). The present study indicates that bullying peers in school as a child, especially frequent bullying perpetration, is associated with increased risk for men's perpetration of IPV as an adult. The effect remains strong after controlling for common prior risk factors for both bullying and IPV perpetration. Future research is needed to discern the mechanisms and underlying root causes of abusive behavior, such as power and control, as a means to prevent violence perpetration across settings and life stages.

Affective Awareness in Parenting of Fathers with Co-Occurring Substance Abuse and Intimate Partner Violence

Stover, Carla Smith; Spink, Andrea

2013-01-01

Purpose Few studies have examined the parenting of fathers with co-occurring Substance Abuse (SA) and Intimate Partner Violence (IPV) problems. None have specifically interviewed men with these co-occurring issues using qualitative methods about their reflective functioning in relation to their children. This qualitative study was designed to provide evidence of the reflective capacity of fathers with co-occurring SA and IPV. Approach To assess this, men were asked to describe examples of negative emotions they experienced as parents and how they perceived their children responded to those emotions. Forty fathers with co-occurring SA and IPV were interviewed using the Revised Parent Development Interview. Interviews were coded for reflective functioning and for themes that emerged related to angry and guilty feelings these fathers experienced as parents. Findings Overall, fathers in the sample had a very limited capacity to think about the thoughts and feelings of their children. The desire to spend more time with their child and an inability to provide financially were two common themes. Anger toward the child’s mother for not providing adequate care and a focus on shielding the child from his anger were also reported frequently. Fathers did not report feelings of guilt related to their substance use or aggression in their relationships. Originality This paper is one of the first to explore reflective functioning of fathers with co-occurring IPV and SA. These findings are discussed in relation to their implications for intervention with fathers with co-occurring SA and IPV issues. PMID:23710257

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).

This research examined the prevalence and correlates of intimate partner violence (IPV) among younger, middle-aged, and older Korean American women. Data were drawn from telephone interviews of a population-based, representative probability sample (N = 592) of female adults of Korean descent residing in California, with a completion rate of 70%. Data were grouped by age. In each group, psychological aggression was the most common type of IPV in the past year, followed by a moderate form of sexual coercion, while physical assault and injury were infrequent. Immigration stress was associated with psychological aggression in all three groups, and partner alcohol use was associated in none. Other predictors varied by group. Results suggest that psychological abuse is a serious issue, and that women’s life stage is an important consideration in IPV among Korean Americans. Findings, which sometimes diverged from those of prior studies of this population, merit further investigation. PMID:23645971

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+.

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.

Beyond deficits: intimate partner violence, maternal parenting, and child behavior over time.

Exposure to intimate partner violence (IPV) has negative consequences for children's well-being and behavior. Much of the research on parenting in the context of IPV has focused on whether and how IPV victimization may negatively shape maternal parenting, and how parenting may in turn negatively influence child behavior, resulting in a deficit model of mothering in the context of IPV. However, extant research has yet to untangle the interrelationships among the constructs and test whether the negative effects of IPV on child behavior are indeed attributable to IPV affecting mothers' parenting. The current study employed path analysis to examine the relationships among IPV, mothers' parenting practices, and their children's externalizing behaviors over three waves of data collection among a sample of 160 women with physically abusive partners. Findings indicate that women who reported higher levels of IPV also reported higher levels of behavior problems in their children at the next time point. When parenting practices were examined individually as mediators of the relationship between IPV and child behavior over time, one type of parenting was significant, such that higher IPV led to higher authoritative parenting and lower child behavior problems [corrected]. On the other hand, there was no evidence that higher levels of IPV contributed to more child behavior problems due to maternal parenting. Instead, IPV had a significant cumulative indirect effect on child behavior via the stability of both IPV and behavior over time. Implications for promoting women's and children's well-being in the context of IPV are discussed.

Childhood maltreatment is considered a crucial explanatory variable for intimate partner violence (IPV) in adulthood. However, a developmental multifactorial model for the etiology of IPV is not shared by researchers yet. This study has investigated the role of a wide range of childhood maltreatments and family and social dysfunctions in predicting IPV; furthermore, it tests a model where childhood maltreatment mediates the relationship between environmental dysfunctions and IPV. The sample included 78 women: IPV (38) and non-IPV (40). The Italian version of the Childhood Experience of Care and Abuse (CECA) Interview was used to assess the presence of adverse childhood experiences. The Revised Conflict Tactics Scale (CTS-2) and the IPV History Interview were used to assess IPV in the last year and lifetime, respectively. The results of a multivariate logistic regression model have indicated that only sexual (odds ratio [OR] = 4.24) and psychological (OR = 3.45) abuse significantly predicted IPV; with regard to association between IPV and environmental dysfunctions, only poor social support (OR = 8.91) significantly predicted IPV. The results of a mediation model have shown that childhood psychological and sexual abuse, in association with each other, partially mediate the relationship between poor social support and IPV. The findings from this study pinpoint poor social support as an important predictor of IPV so far neglected in the literature on the developmental antecedents of IPV. They also support the theoretical assumption according to which dysfunctional environmental variables and types of childhood maltreatment interacting with each other may influence development outcomes.

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

Text analysis of the transcripts of 26 calls made to a Chinese crisis hotline by victims of intimate partner violence (IPV) reporting thoughts or acts of self-harm abstracted information on victims' patterns of self-harm and the relationship of their self-harm to IPV. Specific violent episodes often triggered self-harm. Victims considered self-harm a method for airing painful emotions caused by abuse or as a last resort to escape by dying when they saw no other options and were no longer able to endure the violence. We also elaborate on callers' discussions of barriers to accessing support, sociocultural pressures to preserve "face" and family, and restrictive gender roles that contribute to their self-harm behaviors.

Background Intimate Partner violence (IPV) is one of the common forms of violence against women and is a global public health problem that transcends social, economic, religious and cultural groups. It is often perceived as a private problem or a normal part of life but it contributes greatly to morbidity and mortality. Objective To assess the prevalence and correlates of intimate partner violence by male civil servants in Oyo State Secretariat Ibadan, Nigeria. Methods A cross-sectional study was conducted using a multi-stage sampling technique. A total of 609 respondents completed a pre-tested self-administered questionnaire. Data were analysed using SPSS version 18 and STATA version 12. Chi-square statistic was used to test associations between categorical variables and predictors of perpetration of intimate partner violence were determined using logistic regression model at a level of statistical significance of 5%. Result The mean age was 38.8±9.9 years and about 74.5% were married. The prevalence of IPV perpetration in the 12 months preceding the study was 66.0%. The prevalence of controlling behaviour was 52.2%, psychological abuse − 31.2%, sexual violence − 23.0%, and physical violence − 11.7%. The predictors of perpetrating any form of IPV included previous history of physical fight with another woman [OR: 2.4 (95% CI: 1.30–3.40)], having a negative attitude towards wife beating [OR 2.5 [95% CI: 1.85–3.42], childhood exposure to parental IPV [OR: 2.1 (95% CI: 1.30–3.41)] and use of alcohol [OR: 1.6 (95% CI: 1.14–2.15]. Conclusion The different types of IPV were prevalent among the male civil servants, despite their educational status. Strategies to stop IPV should include male education to change attitudes that encourage violence in relationships to use of non-violent conflict resolution strategies. Education should also include the dangers of alcohol abuse and involvement in physical fights. PMID:26681824

Systematic Review of Mucosal Immunity Induced by Oral and Inactivated Poliovirus Vaccines against Virus Shedding following Oral Poliovirus Challenge

2012-01-01

Inactivated poliovirus vaccine (IPV) may be used in mass vaccination campaigns during the final stages of polio eradication. It is also likely to be adopted by many countries following the coordinated global cessation of vaccination with oral poliovirus vaccine (OPV) after eradication. The success of IPV in the control of poliomyelitis outbreaks will depend on the degree of nasopharyngeal and intestinal mucosal immunity induced against poliovirus infection. We performed a systematic review of studies published through May 2011 that recorded the prevalence of poliovirus shedding in stool samples or nasopharyngeal secretions collected 5–30 days after a “challenge” dose of OPV. Studies were combined in a meta-analysis of the odds of shedding among children vaccinated according to IPV, OPV, and combination schedules. We identified 31 studies of shedding in stool and four in nasopharyngeal samples that met the inclusion criteria. Individuals vaccinated with OPV were protected against infection and shedding of poliovirus in stool samples collected after challenge compared with unvaccinated individuals (summary odds ratio [OR] for shedding 0.13 (95% confidence interval [CI] 0.08–0.24)). In contrast, IPV provided no protection against shedding compared with unvaccinated individuals (summary OR 0.81 [95% CI 0.59–1.11]) or when given in addition to OPV, compared with individuals given OPV alone (summary OR 1.14 [95% CI 0.82–1.58]). There were insufficient studies of nasopharyngeal shedding to draw a conclusion. IPV does not induce sufficient intestinal mucosal immunity to reduce the prevalence of fecal poliovirus shedding after challenge, although there was some evidence that it can reduce the quantity of virus shed. The impact of IPV on poliovirus transmission in countries where fecal-oral spread is common is unknown but is likely to be limited compared with OPV. PMID:22532797

The value of intervening for intimate partner violence in South African primary care: project evaluation

Mash, Robert James

2011-01-01

Objectives Intimate partner violence (IPV) is an important contributor to the burden of disease in South Africa. Evidence-based approaches to IPV in primary care are lacking. This study evaluated a project that implemented a South African protocol for screening and managing IPV. This article reports primarily on the benefits of this intervention from the perspective of women IPV survivors. Design This was a project evaluation involving two urban and three rural primary care facilities. Over 4–8 weeks primary care providers screened adult women for a history of IPV within the previous 24 months and offered referral to the study nurse. The study nurse assessed and managed the women according to the protocol. Researchers interviewed the participants 1 month later to ascertain adherence to their care plan and their views on the intervention. Results In total, 168 women were assisted and 124 (73.8%) returned for follow-up. Emotional (139, 82.7%), physical (115, 68.5%), sexual (72, 42.9%) and financial abuse (72, 42.9%) was common and 114 (67.9%) were at high/severe risk of harm. Adherence to the management plan ranged from testing for syphilis 10/25 (40.0%) to consulting a psychiatric nurse 28/58 (48.3%) to obtaining a protection order 28/28 (100.0%). Over 75% perceived all aspects of their care as helpful, except for legal advice from a non-profit organisation. Women reported significant benefits to their mental health, reduced alcohol abuse, improved relationships, increased self-efficacy and reduced abusive behaviour. Two characteristics seemed particularly important: the style of interaction with the nurse and the comprehensive nature of the assessment. Conclusion Female IPV survivors in primary care experience benefit from an empathic, comprehensive approach to assessing and assisting with the clinical, mental, social and legal aspects. Primary care managers should find ways to integrate this into primary care services and evaluate it further. PMID:22146888

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.

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.

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.

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.

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.

Although research examining intimate partner violence (IPV) has expanded in recent years, there has been relatively little examination of the related demographic and psychosocial factors, as well as mental health outcomes, for IPV before and during pregnancy, especially in a Mexican American population. The current study provides a snapshot of the occurrence of IPV in a community sample of low-income, perinatal Mexican American women (n = 320). Results indicated that 13.1% of the women reported IPV before pregnancy and 11.3% reported IPV during pregnancy. For both IPV before and during pregnancy, women born in the U.S. were more likely to report IPV than foreign born women. For IPV before pregnancy, women who were not in a serious romantic relationship or reported a history of childhood trauma were also more likely to report IPV. For IPV during pregnancy, women who reported higher general stress and lower social support were also more likely to report IPV. Finally, the current study provided strong evidence that a history of IPV predicted elevated postpartum depressive symptoms, above and beyond the impact of prenatal depressive symptoms. This study brings greater awareness to a complex and harmful situation in an understudied population. Results are discussed in terms of the relation between demographic and psychosocial risk for IPV before and during pregnancy, acculturation, and postpartum depressive symptoms, as well as the implications for the development of future prevention and intervention programs.

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 (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.

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

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

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.

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.

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.

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.

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

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.

Pereira, Ana Rita; Vieira, Duarte Nuno; Magalhães, Teresa

2013-11-01

Intimate partner violence (IPV) is an important cause of women's health and socio-familial severe problems, the most extreme being the victims' homicide. This is the first nationwide Portuguese autopsy-based and judicial-proven study about female intimate partner homicide. At least 62 women over 15 years old were killed by current or former men-intimate partners, corresponding to an IPV-related female mortality rate of 0.44/100.000 women; intimate partner violence was the reason of homicide in 60.8% of all autopsied women. The typical Portuguese victim showed to be a young adult woman, employed, killed by a current husband in a long-term relationship, usually with children in common and with a history of previous IPV. The typical Portuguese perpetrator showed to be older than the victim, employed, owning a firearm and without criminal records. At the time of the fatal event 59.7% of the relationships were current. In 57.9% of the former relationships women were killed during the 1st year after its terminus. Near half of the perpetrators attempted or committed suicide afterward. Most women were killed by gunshot wounds (45.2%), especially in the thorax (48.4%), with multiple fatal injuries; 56.5% also presented non-fatal injuries. The detection of prior IPV and the risk evaluation seems to be fundamental to decrease these fatal outcomes, but also, the prevention of perpetrators' alcohol abuse and carrying weapons. This work emphasizes the need to deepen the research on this issue, aiming to contribute to prevent both fatal and non-fatal IPV-related cases.

Objective Intimate partner violence (IPV) is increasingly recognized as an important cause of maternal and perinatal morbidity. We assessed the relation between IPV and risk of spontaneous preterm birth (PTB) among Peruvian women. Methods The study was conducted among 479 pregnant women who delivered a preterm singleton infant (<37 weeks gestation) and 480 controls (≥37 weeks gestation). Participants’ exposure to physical and emotional violence during pregnancy was collected during in-person interviews conducted after delivery and while patients were in hospital. Odds ratios (aOR) and 95% confidence intervals (CI) were estimated from logistic regression models. Results The prevalence of any IPV during pregnancy was 52.2% among cases and 34.6% among controls. Compared with those reporting no exposure to IPV during pregnancy, women reporting any exposure had a 2.1-fold increased risk of PTB (95% CI 1.59–2.68). The association was attenuated slightly after adjusting for maternal age, pre-pregnancy weight, and other covariates (OR=1.99; 95% CI: 1.52–2.61). Emotional abuse in the absence of physical violence was associated with a 1.6-fold (95% CI 1.21–2.15) increased risk of PTB. Emotional and physical abuse during pregnancy was associated with a 4.7-fold increased risk of PTB (95% CI 2.74–7.92). Associations of similar directions and magnitudes were observed when PTB were sub-categorized according to clinical presentation or severity. Conclusion IPV among pregnant women is common and is associated with an increased risk of PTB. Our findings and those of others support recent calls for coordinated global health efforts to prevent violence against women. PMID:22527763

Intimate partner violence among women veterans by sexual orientation.

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.

Replacing live-attenuated oral poliovirus vaccines (OPV) with inactivated poliovirus vaccines (IPV) is part of the global strategy to eradicate poliomyelitis. 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.

Spouse abuse so called intimate partner violence (IPV) is a common problem in the world. This survey was conducted to identify IPV prevalence and related factors in district health centers in Hamadan, western Iran, in hope that, by identifying risk factors, preventive guidelines could be understood. In this descriptive analytic cross sectional study, 600 married women from six district health centers in Hamadan, western Iran were randomly enrolled in 2007. For gathering information we used a questionnaire which included demographic and specific questions about IPV, based on WHO guidelines. For increasing validity of results, questionnaires were nameless and participants were ensured about concealment of their identities. Finally data analyzed by SPSS software (version15). Wife abuse was identified in 34.2% of participants. For understanding IPV risk factors, we used logistic regression method and 27 variables were enrolled in the equation and finally 4 variables were statistically significant to wife abuse (P< 0.05). These variables were: weak religious believe of men, history of wife abuse in participant's mothers, men's criminal history and finally men's alcoholic abuse Wife abuse was prevalent in this survey, so that 1 from 3 women was abused by their husbands. Other similar investigations in different countries also verify this result. Because of so many women who disclaim violence due to cultural texture and religious believe, it is believed that, intimate partner violence is more than those being reported.

Identifying signs and symptoms of intimate partner violence in an oncology setting.

Mick, JoAnn

2006-08-01

Domestic violence (DV), or intimate partner violence (IPV), is a prevailing problem in public health. Often, healthcare providers may be the first people that victims of DV will approach to reveal their problem or seek assistance. IPV is a pattern of control using assault and intimidating behaviors that has devastating effects on individuals, their families, and communities. Oncology nurses need to become familiar with common indicators of DV so that signs and symptoms of abuse can be identified when assessing patients in an oncology setting. Standards of oncology nursing practice support that the psychosocial impact of cancer on patients and their families or significant others needs to be considered at all stages of diagnosis and treatment. The psychosocial impact of other personal situations or concerns, such as IPV, can add to the complexity of cancer management. Routine screening for signs and symptoms of psychosocial distress helps identify patients who require additional interventions. Oncology nursing practice is based on a holistic approach to patient care, which supports that identification of physical and psychosocial needs are equally important. Oncology nursing provides many unique opportunities to help patients cope with cancer. Routine nursing assessment for signs and symptoms of abuse will provide an opportunity to assist patients with cancer to manage not only the life-threatening aspects of their diagnosis but also the life-threatening aspects of IPV.

Injuries from intimate partner and sexual violence: Significance and classification systems.

2012-07-01

While intimate partner violence (IPV) and sexual violence (SV) are highly associated with injury, the healthcare and legal significance of these injuries is controversial. Herein we propose to explore the significance of injury in IPV and SV and examine the current status of injury classification systems from the perspectives of the healthcare and criminal justice systems. We will review current injury classification systems and suggest a typology of injury that could be tested empirically. Within the published literature, we found that no commonly accepted injury typology exists. While nuanced and controversial issues surround the role of injury detection in the sexual assault forensic examination, enough evidence exists to support the continued pursuance of a scientific approach to injury classification. We propose an injury typology that is measurable, is applicable to the healthcare setting and criminal justice system, and allows us to use uses a matrix approach that includes a severity score, anatomic location, and injury type. We suggest a typology that might be used for further empirical testing on the validity and reliability of IPV and SV injury data. We recommend that the community of scientists concerned about IPV and SV develop a more rigorous injury classification system that will improve the quality of forensic evidence proffered and decisions made throughout the criminal justice process.

Kamimura, Akiko; Bybee, Deborah; Yoshihama, Mieko

2014-09-01

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.

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.

Ambivalent Sexism, Alcohol Use, and Intimate Partner Violence Perpetration.

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.

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.

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.

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.

Globally, inequality between men and women manifests in a variety of ways. In particular, gender inequality increases the risk of perpetration of violence against women (VAW), especially intimate partner violence (IPV), by males. The World Health Organization (WHO) estimates that 35 % of women have experienced physical, psychological and/or sexual IPV at least once in their lives, making IPV unacceptably common. In 2006, the Maria da Penha Law on Domestic and Family Violence, became the first federal law to regulate VAW and punish perpetrators in Brazil. This study examines the relationship between Brazilian VAW legislation and male perpetration of VAW by comparing reported prevalence of IPV before and after the enactment of the Maria da Penha Law. To assess changes in magnitude of IPV before and after the law, we used data from the 2013 Brazilian National Health Survey; we replicated the analyses conducted for the WHO Multi-Country Study on Women's Health and Domestic Violence Against Women-whose data were collected before the passage of the Maria da Penha Law. We compare findings from the two studies. Our analyses show an increase in the reported prevalence of physical violence, and a decrease in the reported prevalence of sexual and psychological violence. The increase may result from an actual increase in physical violence, increased awareness and reporting of physical violence, or a combination of both factors. Additionally, our analysis revealed that in the urban setting of São Paulo, physical violence was more likely to be severe and occur in the home; meanwhile, in the rural state of Pernambuco, physical violence was more likely to be moderate in nature and occur in public. The Maria da Penha Law increased attention and resources for VAW response and prevention; however, its true impact remains unmeasured. Our data suggest a need for regular, systematic collection of comparable population-based data to accurately estimate the true prevalence of IPV in Brazil. Furthermore, such data may inform policy and program planning to address specific needs across diverse settings including rural and urban communities. If routinely collected over time, such data can be used to develop policies and programs that address all forms of IPV, as well as evidence-based programs that address the social and cultural norms that support other forms of VAW and gender inequality.

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 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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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

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.

Anxiety and posttraumatic stress symptom pathways to substance use problems among community women experiencing intimate partner violence.

Jaquier, Véronique; Flanagan, Julianne C; Sullivan, Tami P

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.

Analysis of the dose-sparing effect of adjuvanted Sabin-inactivated poliovirus vaccine (sIPV).

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.

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

PubMed

Hilton, N Zoe; Ham, Elke; Green, Michelle M

2016-10-01

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.

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.

Although a wealth of research has examined the effects of parental mood disorders on offspring maladjustment, studies have not identified whether elevated interparental violence (IPV) may be an exacerbating influence in this pathway. This study examined levels of physical IPV perpetration and victimization in mothers with unipolar depression or Bipolar Disorder (BD) and the processes by which maternal physical IPV moderated adolescents’ physical aggression in families with maternal mood disorders. Mothers with lifetime mood disorders were predicted to have elevated IPV compared to well mothers, and maternal IPV was expected to moderate the association between lifetime mood disorders and adolescent aggression. Participants included 61 intact families with maternal depression (n = 24), BD (n = 13), or well mothers (n = 24) and two siblings (ages 10 to 18 years). Using the Conflict Tactics Scale, mothers reported on IPV perpetration and victimization, and adolescents reported on physical aggression. Mothers with BD reported significantly higher IPV perpetration, but not victimization, than depressed or well mothers. An interaction between maternal BD and IPV perpetration was a significant predictor of adolescent aggression. Main effects of maternal IPV victimization and interaction effects of maternal depression and either type of IPV on adolescent aggression were not significant. Adolescents of mothers who have BD and perpetrate IPV may be particularly vulnerable to being aggressive. Prevention and policy efforts to deter transmission of aggression in high-risk families should target families with maternal BD and intervene at the level of conflict resolution within the family.

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.

Women in Bangladesh experience high rates of Intimate Partner Violence (IPV). IPV is more prevalent against income earning women compared to their non-earning counterparts, and Workplace Violence (WPV) is also common. Such violence is a violation of women's rights, and also constrains them from contributing to their personal growth, household, community and the economy at large. There is limited evidence on what works to prevent IPV and WPV amongst garment workers. This paper describes an evaluation of HERrespect, an intervention which aims to reduce IPV and WPV against female garment workers in and around Dhaka, Bangladesh. The trial employs a quasi-experimental design, with four intervention and four control factories. In the intervention factories a randomly selected cohort of married female line workers, a cohort of male line workers, and all middle management staff received the intervention. The intervention strategies involved (1) gender transformative group-based training for workers and management staff; (2) joint session between workers (15 female and male) and middle-management staff; (3) factory-wide activities; (4) awareness raising among top management; (5) factory policy review and development and 6) a community based campaign. For the evaluation, a cohort of randomly selected female workers and a cohort of selected management staff have been established. All workers (n = 800) and management staff (n = 395) from these cohorts were interviewed at baseline using two different questionnaires, and will be interviewed in the endline, 24 months post-baseline. Intention to treat analysis will be used for assessing the impact of HERrespect, comparing the intervention and control factories. To our knowledge this is the first study that seeks to evaluate the impact on IPV and WPV, of group sessions with female workers, male workers, and management; factory-wide campaigns and a community intervention among female garment workers in Bangladesh. Apart from informing programmers and policy makers about intervention effectiveness in reducing IPV and WPV against female garment workers this study will also present evidence on an intervention tailored to the situation in the garment sector, which makes HERrespect scalable.

Child maltreatment and eating disorders are significant public health problems. Yet, to date, research has focused on the role of child physical and sexual abuse in eating-related pathology. This is despite the fact that globally, exposure to emotional abuse, emotional neglect and intimate partner violence are the three of the most common forms of child maltreatment. The objective of the present study is to systematically identify and critically review the literature examining the association between child emotional abuse (EA), emotional neglect (EN), and exposure to intimate partner violence (IPV) and adult eating-disordered behavior and eating disorders. A systematic search was conducted of five electronic databases: Medline, Embase, PsycINFO, CINAHL, and ERIC up to October 2015 to identify original research studies that investigated the association between EA, EN and children's exposure to IPV, with adult eating disorders or eating-disordered behavior using a quantitative research design. Database searches were complemented with forward and backward citation chaining. Studies were critically appraised using the Quality in Prognosis Studies (QUIPS) tool. A total of 5556 publications were screened for this review resulting in twenty-three articles included in the present synthesis. These studies focused predominantly on EA and EN, with a minority examining the role of child exposure to IPV in adult eating-related pathology. Prevalence of EA and EN ranged from 21.0% to 66.0%, respectively. No prevalence information was provided in relation to child exposure to IPV. Samples included predominantly White women. The methodological quality of the available literature is generally low. Currently, the available literature precludes the possibility of determining the extent to which EA, EN or child exposure to IPV have independent explanatory influence in adult eating-related pathology above what has been identified for physical and sexual abuse. While a large proportion of adults with eating disorders or eating-disordered behavior report EA, EN, or child exposure to IPV , there is a paucity of high-quality evidence about these relationships.

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.

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.

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.

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.

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

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.

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).

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.

2016-01-01

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

Intimate partner violence and condom negotiation efficacy among gay and bisexual men in Atlanta.

PubMed

Stephenson, Rob; Freeland, Ryan; Finneran, Catherine

2016-04-28

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.

To assess incidence and risk factors of intimate partner violence (IPV) during pregnancy among a sample of women from Egypt and to evaluate its impact on maternal and fetal adverse health outcomes. After obtaining ethical approval, a total of 1,857 women aged 18 - 43 years completed the study and were investigated using an interview questionnaire. The questionnaire contains five main items: demographic characteristics of women, intimate partner characteristics, assessment of IPV during current pregnancy, and assessment of maternal as well as fetal/neonatal adverse outcomes. Women were also examined to detect signs of violence and identify injuries. Exposure to IPV during pregnancy was reported among 44.1% of the studied women. Emotional violence was the most common form. Women exposed to violence were of younger age, higher parity, and lower educational level. Their partners were older, less educated, and more likely to be addicted to drugs and alcohol. Women were also found to have significantly higher incidence of adverse pregnancy outcomes (miscarriage, preterm labor, and premature rupture of membrane), and fetal/neonatal adverse outcomes (fetal distress, fetal death, and low birth weight). A total of 297 cases had been exposed to physical violence (15.9%) vs 32.6% and 10% exposed to emotional and sexual violence, respectively. The most common form of physical violence was kicking. Violence during pregnancy is prevalent among Egyptian women. Exposure to violence was a significant risk factor for multiple adverse maternal and fetal health outcomes.

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.

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.

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 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.

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.

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.

Intimate Partner Violence and Depression Symptom Severity among South African Women during Pregnancy and Postpartum: Population-Based Prospective Cohort Study

2016-01-01

Background Violence against women by intimate partners remains unacceptably common worldwide. The evidence base for the assumed psychological impacts of intimate partner violence (IPV) is derived primarily from studies conducted in high-income countries. A recently published systematic review identified 13 studies linking IPV to incident depression, none of which were conducted in sub-Saharan Africa. To address this gap in the literature, we analyzed longitudinal data collected during the course of a 3-y cluster-randomized trial with the aim of estimating the association between IPV and depression symptom severity. Methods and Findings We conducted a secondary analysis of population-based, longitudinal data collected from 1,238 pregnant women during a 3-y cluster-randomized trial of a home visiting intervention in Cape Town, South Africa. Surveys were conducted at baseline, 6 mo, 18 mo, and 36 mo (85% retention). The primary explanatory variable of interest was exposure to four types of physical IPV in the past year. Depression symptom severity was measured using the Xhosa version of the ten-item Edinburgh Postnatal Depression Scale. In a pooled cross-sectional multivariable regression model adjusting for potentially confounding time-fixed and time-varying covariates, lagged IPV intensity had a statistically significant association with depression symptom severity (regression coefficient b = 1.04; 95% CI, 0.61–1.47), with estimates from a quantile regression model showing greater adverse impacts at the upper end of the conditional depression distribution. Fitting a fixed effects regression model accounting for all time-invariant confounding (e.g., history of childhood sexual abuse) yielded similar findings (b = 1.54; 95% CI, 1.13–1.96). The magnitudes of the coefficients indicated that a one–standard-deviation increase in IPV intensity was associated with a 12.3% relative increase in depression symptom severity over the same time period. The most important limitations of our study include exposure assessment that lacked measurement of sexual violence, which could have caused us to underestimate the severity of exposure; the extended latency period in the lagged analysis, which could have caused us to underestimate the strength of the association; and outcome assessment that was limited to the use of a screening instrument for depression symptom severity. Conclusions In this secondary analysis of data from a population-based, 3-y cluster-randomized controlled trial, IPV had a statistically significant association with depression symptom severity. The estimated associations were relatively large in magnitude, consistent with findings from high-income countries, and robust to potential confounding by time-invariant factors. Intensive health sector responses to reduce IPV and improve women’s mental health should be explored. PMID:26784110

Correlates of intimate partner violence against women during a time of rapid social transition in Rwanda: analysis of the 2005 and 2010 demographic and health surveys.

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.

Parent-child aggression, adult-partner violence, and child outcomes: A prospective, population-based study.

PubMed

Maneta, E K; White, M; Mezzacappa, E

2017-06-01

Parent-child physical aggression (PCPA) and adult intimate partner violence (IPV) are common forms of family violence that often co-occur. Their deleterious effects on children and adolescents have been well documented. However, important questions remain regarding whether the type of violence exposure, the experience of one or both forms, the chronicity of violent experiences, and the age, gender, and SES of the child, differentially influence developmental outcomes. Data on 2810 children from the Project on Human Development in Chicago Neighborhoods were analyzed. Children aged 3-9 at the outset were assessed three times, at 3-year intervals. Primary caregivers reported on IPV, PCPA, and children's externalizing and internalizing symptoms. Children's externalizing and internalizing symptoms were examined as a function of time, age, gender, socioeconomic status (SES), and the time-varying effects of cumulative IPV and PCPA exposure. Cumulative experiences of IPV and PCPA each adversely affected the developmental trajectories of both externalizing and internalizing symptoms, but in different ways; and they did so independently of participants' age, gender, or SES, which all functioned as significant, independent predictors of child outcomes. PCPA was by far the more potent of the two forms of violence; and when both forms occurred, they worked additively to affect outcomes. Important questions remain regarding the reasons for the differential potency of these two forms of family violence on childhood symptoms, and related implications for interventions, as well as for later adult behavior.

Understanding economic abuse in the lives of survivors.

2012-02-01

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.

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

2010-09-01

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.

2015-05-01

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, 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.

This study explores the perceptions of a wide range of stakeholders in Malawi towards the mental health impact of intimate partner violence (IPV) and the capacity of health services for addressing these. In-depth interviews (IDIs) and focus group discussions (FGDs) were conducted in three areas of Blantyre district, and in two additional districts. A total of 10 FGDs, 1 small group, and 14 IDIs with health care providers; 18 FGDs and 1 small group with male and female, urban and rural community members; 7 IDIs with female survivors; and 26 key informant interviews and 1 small group with government ministry staff, donors, gender-based violence service providers, religious institutions, and police were conducted. A thematic framework analysis method was applied to emerging themes. The significant mental health impact of IPV was mentioned by all participants and formal care seeking was thought to be impeded by social pressures to resolve conflict, and fear of judgemental attitudes. Providers felt inadequately prepared to handle the psychosocial and mental health consequences of IPV; this was complicated by staff shortages, a lack of clarity on the mandate of the health sector, as well as confusion over the definition and need for 'counselling'. Referral options to other sectors for mental health support were perceived as limited but the restructuring of the Ministry of Health to cover violence prevention, mental health, and alcohol and drug misuse under a single unit provides an opportunity. Despite widespread recognition of the burden of IPV-associated mental health problems in Malawi, there is limited capacity to support affected individuals at community or health sector level. Participants highlighted potential entry points to health services as well as local and national opportunities for interventions that are culturally appropriate and are built on local structures and resilience.

Although a wealth of research has examined the effects of parental mood disorders on offspring maladjustment, studies have not identified whether elevated interparental violence (IPV) may be an exacerbating influence in this pathway. This study examined levels of physical IPV perpetration and victimization in mothers with unipolar depression or Bipolar Disorder (BD) and the processes by which maternal physical IPV moderated adolescents' physical aggression in families with maternal mood disorders. Mothers with lifetime mood disorders were predicted to have elevated IPV compared to well mothers, and maternal IPV was expected to moderate the association between lifetime mood disorders and adolescent aggression. Participants included 61 intact families with maternal depression (n = 24), BD (n = 13), or well mothers (n = 24) and two siblings (ages 10 to 18 years). Using the Conflict Tactics Scale, mothers reported on IPV perpetration and victimization, and adolescents reported on physical aggression. Mothers with BD reported significantly higher IPV perpetration, but not victimization, than depressed or well mothers. An interaction between maternal BD and IPV perpetration was a significant predictor of adolescent aggression. Main effects of maternal IPV victimization and interaction effects of maternal depression and either type of IPV on adolescent aggression were not significant. Adolescents of mothers who have BD and perpetrate IPV may be particularly vulnerable to being aggressive. Prevention and policy efforts to deter transmission of aggression in high-risk families should target families with maternal BD and intervene at the level of conflict resolution within the family.

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.

Maternal experience of intimate partner violence and low birth weight of children: A hospital-based study in Bangladesh

2017-01-01

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.

2014-01-01

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.

NASA Lewis advanced IPV nickel-hydrogen technology

Individual pressure vessel (IPV) nickel-hydrogen technology was advanced at NASA Lewis and under Lewis contracts. Some of the advancements are as follows: to use 26 percent potassium hydroxide electrolyte to improve cycle life and performance, to modify the state of the art cell design to eliminate identified failure modes and further improve cycle life, and to develop a lightweight nickel electrode to reduce battery mass, hence reduce launch and/or increase satellite payload. A breakthrough in the LEO cycle life of individual pressure vessel nickel-hydrogen battery cells was reported. The cycle life of boiler plate cells containing 26 percent KOH electrolyte was about 40,000 accelerated LEO cycles at 80 percent DOD compared to 3,500 cycles for cells containing 31 percent KOH. Results of the boiler plate cell tests have been validated at NWSC, Crane, Indiana. Forty-eight ampere-hour flight cells containing 26 and 31 percent KOH have undergone real time LEO cycle life testing at an 80 percent DOD, 10 C. The three cells containing 26 percent KOH failed on the average at cycle 19,500. The three cells containing 31 percent KOH failed on the average at cycle 6,400. Validation testing of NASA Lewis 125 Ah advanced design IPV nickel-hydrogen flight cells is also being conducted at NWSC, Crane, Indiana under a NASA Lewis contract. This consists of characterization, storage, and cycle life testing. There was no capacity degradation after 52 days of storage with the cells in the discharged state, on open circuit, 0 C, and a hydrogen pressure of 14.5 psia. The catalyzed wall wick cells have been cycled for over 22,694 cycles with no cell failures in the continuing test. All three of the non-catalyzed wall wick cells failed (cycles 9,588; 13,900; and 20,575). Cycle life test results of the Fibrex nickel electrode has demonstrated the feasibility of an improved nickel electrode giving a higher specific energy nickel-hydrogen cell. A nickel-hydrogen boiler plate cell using an 80 mil thick, 90 percent porous Fibrex nickel electrode has been cycled for 10,000 cycles at 40 percent DOD.

INTIMATE PARTNER VIOLENCE AND DEPRESSIVE SYMPTOMS DURING ADOLESCENCE AND YOUNG ADULTHOOD

2014-01-01

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).

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

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.

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

PubMed

Nagae, Miyoko; Dancy, Barbara L

2010-04-01

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.

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.

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.

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.

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

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.

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.

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.

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.

Contribution of family violence to the intergenerational transmission of externalizing behavior.

Ehrensaft, Miriam K; Cohen, Patricia

2012-08-01

Research finds that early antisocial behavior is a risk for later intimate partner violence (IPV) perpetration and victimization, and that children's exposure to their parents' IPV is a risk for subsequent behavior problems. This study tests whether intimate violence (IPV) between partners contributes independently to the intergenerational transmission of antisocial behavior, using the Children in the Community Study, a representative sample (N = 821) followed for over 25 years in 6 assessments. The present study includes a subsample of parents (N = 678) and their offspring (N = 396). We test the role of three mechanisms by which IPV may influence child antisocial behavior-parental psychopathology, parenting practices, and child self-regulation. Results suggest that IPV independently increased the risk for offspring externalizing problems, net of the effects of parental history of antisocial behavior and family violence. IPV also increased the risk for parental post traumatic stress disorder (PTSD) and alcohol use disorder 2 years later, but not for major depressive disorder. Alcohol use disorder independently increased the risk for offspring externalizing behavior, but IPV continued to predict offspring externalizing net of parental alcohol use. Parenting, particularly low satisfaction with the child, was significantly associated with both IPV and externalizing behavior, but did not mediate the effects of IPV on externalizing. IPV predicted higher levels of emotional expressivity, aggression and hostile reactivity, and depressive mood in offspring. Implications for future research and prevention are discussed.

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.

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.

College Campus Community Readiness to Address Intimate Partner Violence Among LGBTQ+ Young Adults: A Conceptual and Empirical Examination.

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.

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.

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.

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.

Gendered Perceptions of Intimate Partner Violence Normality: An Experimental Study.

2017-12-01

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

Aviation industries in United States and in Europe are undergoing a major paradigm shift in the introduction of new network technologies. In the US, NASA is also actively investigating the feasibility of IPv6 based networks for the aviation needs of the United States. In Europe, the Eurocontrol lead, Internet Protocol for Aviation Exchange (iPAX) Working Group is actively investigating the various ways of migrating the aviation authorities backbone infrastructure from X.25 based networks to an IPv6 based network. For the last 15 years, the global aviation community has pursued the development and implementation of an industry-specific set of communications standards known as the Aeronautical Telecommunications Network (ATN). These standards are now beginning to affect the emerging military Global Air Traffic Management (GATM) community as well as the commercial air transport community. Efforts are continuing to gain a full understanding of the differences and similarities between ATN and Internet architectures as related to Communications, Navigation, and Surveillance (CNS) infrastructure choices. This research paper describes the implementation of the IPv6 test bed at NASA GRC, and Computer Networks & Software, Inc. and these two test beds are interface to Eurocontrol over the IPv4 Internet. This research work looks into the possibility of providing QoS performance for Aviation application in an IPv6 network as is provided in an ATN based network. The test bed consists of three autonomous systems. The autonomous system represents CNS domain, NASA domain and a EUROCONTROL domain. The primary mode of connection between CNS IPv6 testbed and NASA and EUROCONTROL IPv6 testbed is initially a set of IPv6 over IPv4 tunnels. The aviation application under test (CPDLC) consists of two processes running on different IPv6 enabled machines.

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: 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.

Raj, Anita; McDougal, Lotus

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

Intimate partner violence (IPV) is an important global public health problem. While there is a growing literature on the association between IPV and women's reproductive health (RH) outcomes, most studies are cross-sectional-which weakens inference about the causal effect of IPV on women's RH. This systematic review synthesizes existing evidence from the strongest study designs to estimate the impact of IPV on women's use of contraception. We searched 11 electronic databases from January of 1980 to 3 December 2013 and reviewed reference lists from systematic reviews for studies examining IPV and contraceptive use. To be able to infer causality, we limited our review to studies that had longitudinal measures of either IPV or women's use of contraception. Of the 1,574 articles identified by the search, we included 179 articles in the full text review and extracted data from 12 studies that met our inclusion criteria. We limited the meta-analysis to seven studies that could be classified as subject to low or moderate levels of bias. Women's experience of IPV was associated with a significant reduction in the odds of using contraception (n = 14,866; OR: 0.47; 95% CI: 0.25, 0.85; I2 = 92%; 95% CII2: 87%, 96%). Restricting to studies that measured the effect of IPV on women's use of partner dependent contraceptive methods was associated with a reduction in the heterogeneity of the overall estimate. In the three studies that examined women's likelihood of using male condoms with their partners, experience of IPV was associated with a significant decrease in condom use (OR: 0.48; 95% CIOR: 0.32, 0.72; I2 = 51%; 95% CII2: 0%, 86%). IPV is associated with a reduction in women's use of contraception; women who experience IPV are less likely to report using condoms with their male partners. Family planning and HIV prevention programs should consider women's experiences of IPV.

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.

Intimate partner violence and postpartum contraceptive use: the role of race/ethnicity and prenatal birth control counseling.

Intimate partner violence (IPV) is a major problem that could affect reproductive decision making. The aim of this study is to examine the association between IPV and contraceptive use and assess whether the association varies by receipt of prenatal birth control counseling and race/ethnicity. This study analyzed the 2004-2008 national Pregnancy Risk Assessment Monitoring System (PRAMS) that included 193,310 women with live births in the United States. IPV was determined by questions that asked about physical abuse by a current or former partner in the 12 months before or during pregnancy. The outcome was postpartum contraceptive use (yes vs. no). Multiple logistic regression analyses were conducted to assess the influence of experiencing IPV at different periods (preconception IPV, prenatal IPV, both preconception and prenatal IPV, preconception and/or prenatal IPV). Data were stratified to assess differential effects by race/ethnicity and receipt of birth control counseling. Approximately 6.2% of women reported IPV, and 15.5% reported no postpartum contraceptive use. Regardless of the timing of abuse, IPV-exposed women were significantly less likely to report contraceptive use after delivery. This was particularly true for Hispanic women who reported no prenatal birth control counseling and women of all other racial/ethnic groups who received prenatal birth control counseling. IPV victimization adversely affects the use of contraceptive methods following delivery in women with live births. Birth control counseling by health providers may mitigate these effects; however, the quality of counseling needs further investigation. Better integration of violence prevention services and family planning programs is greatly needed. Consistent with national recommendations by the U.S. Preventive Service Task Force, clinicians and public health workers are strongly encouraged to screen for IPV. Health providers should educate women on effective contraceptive options and discuss long-acting reversible contraceptives that are not partner dependent within the context of abusive relationships.

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.

Help-Seeking Behaviors for Intimate Partner Violence Perpetration by Men Receiving Substance Use Treatment: A Mixed-Methods Secondary Analysis.

PubMed

Hashimoto, Nozomu; Radcliffe, Polly; Gilchrist, Gail

2018-05-01

Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help-seeking for IPV perpetration to increase the likelihood of identification.

At least one-third of women in India experience intimate partner violence (IPV) at some point in adulthood. Our objectives were to describe the prevalence of IPV during pregnancy and after delivery in an urban slum setting, to review its social determinants, and to explore its effects on maternal and newborn health. We did a cross-sectional study nested within the data collection system for a concurrent trial. Through urban community surveillance, we identified births in 48 slum areas and interviewed mothers ~6 weeks later. After collecting information on demographic characteristics, socioeconomic indicators, and maternal and newborn care, we asked their opinions on the justifiability of IPV and on their experience of it in the last 12 months. Of 2139 respondents, 35% (748) said that violence was justifiable if a woman disrespected her in-laws or argued with her husband, failed to provide good food, housework and childcare, or went out without permission. 318 (15%, 95% CI 13, 16%) reported IPV in the year that included pregnancy and the postpartum period. Physical IPV was reported by 247 (12%, 95% CI 10, 13%), sexual IPV by 35 (2%, 95% CI 1, 2%), and emotional IPV by 167 (8%, 95% CI 7, 9). 219 (69%) women said that the likelihood of IPV was either unaffected by or increased during maternity. IPV was more likely to be reported by women from poorer families and when husbands used alcohol. Although 18% of women who had suffered physical IPV sought clinical care for their injuries, seeking help from organizations outside the family to address IPV itself was rare. Women who reported IPV were more likely to have reported illness during pregnancy and use of modern methods of family planning. They were more than twice as likely to say that there were situations in which violence was justifiable (odds ratio 2.6, 95% CI 1.7, 3.4). One in seven women suffered IPV during or shortly after pregnancy. The elements of the violent milieu are mutually reinforcing and need to be taken into account collectively in responding to both individual cases and framing public health initiatives.

They were more than twice as likely to say that there were situations in which violence was justifiable (odds ratio 2.6, 95% CI 1.7, 3.4). Conclusions One in seven women suffered IPV during or shortly after pregnancy. The elements of the violent milieu are mutually reinforcing and need to be taken into account collectively in responding to both individual cases and framing public health initiatives. PMID:24015762

Intimate partner violence (IPV) is recognised as an important public health and social problem, with far reaching consequences for women's physical and emotional health and social well-being. Furthermore, controlling behaviour by a partner has a similar impact on women's well-being, yet little is known about the prevalence of this type of behaviour and other related abuses in Tanzania and in other sub-Saharan African countries. We conducted a cross-sectional study to determine the lifetime and past 12-month prevalence of physical and sexual IPV, economic abuse, emotional abuse and controlling behaviour among ever-partnered women in Mwanza, Tanzania. Women (N = 1049) were enrolled in an ongoing trial (Maisha study) to assess the impact of microfinance combined with gender training on participants' experience IPV, and other related outcomes. Interviews were conducted by same sex interviewers to collect information about socio-demographic characteristics, experiences of specific acts of IPV and abuse, and symptoms of poor mental health status. Overall, about 61% of women reported ever experiencing physical and/or sexual IPV (95% CI: 58-64%) and 27% (95% CI: 24-29%) experienced it in the past 12 months. Partner controlling behaviour was the most prevalent type of abuse with 82% experiencing it in their lifetime and 63% during the past 12 months. Other types of abuses were also common, with 34% of women reporting economic abuse and 39% reporting emotional abuse during the past 12 months. The prevalence of IPV and abuses varied by socio-demographic characteristics, showing much higher prevalence rates among younger women, women with young partners and less educated women. After we adjusted for age and socio-economic status, physical violence (OR = 1.8; 95% CI: 1.3-2.7) and sexual violence (OR = 2.8; 95% CI: 1.9-4.1) were associated with increased reporting of symptoms of poor mental health. Similarly, experience of abuse during the past 12 months was associated with increased reporting of symptoms of poor mental health. The high prevalence of IPV and abuses and its strong links with symptoms of poor mental health underline the urgent need for developing and testing appropriate interventions in settings like Tanzania to tackle both violence and abusive behaviours among intimate partners.

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.

Intimate Partner Violence (IPV) is a significant public health problem with negative health consequences for women and their pregnancies. While social support has a protective effect against IPV and reduces health consequences of violence, its association with experiencing IPV during pregnancy remain less explored. In our study we aimed to determine the effect of social support on IPV during pregnancy among women attending antenatal care in Moshi, Tanzania METHODS: The study was part of a prospective cohort study that assessed the impact of violence on reproductive health of 1,116 participants. Pregnant women were enrolled below 24 weeks of gestation and followed until delivery. The experiences of social support and IPV during pregnancy were assessed at the 34 th week of gestation. Logistic regression analysis was performed to assess the relationship between social support and IPV, with adjustment for potential confounders. The prevalence of IPV during pregnancy was 30.3% where the majority (29.0%) experienced repeated episodes of abuse. Regarding practical social support, having no one to help financially was associated with increased odds of IPV and repeated episodes of abuse during pregnancy, AOR 3.57, (95% CI 1.85 - 6.90) and AOR 3.21, (95% CI 1.69 - 6.11) respectively. For social support in terms of communication, talking to a member of the family of origin at least monthly was associated with decreased odds of IPV and repeated episodes of IPV during pregnancy, AOR 0.46 (95% CI 0.26 - 0.82) and AOR 0.41 (95% CI 0.23 - 0.73) respectively. Perceiving that family of origin will not offer support was associated with a increased odds of IPV and repeated episodes of IPV, AOR 2.29, (95% CI 1.31 - 3.99) and AOR 2.14, (95% CI 1.23 - 3.74) respectively. Nearly one third of women experienced IPV during pregnancy. Social support to women is associated with decreased odds of experiencing IPV during pregnancy. The family of origin plays an important role in providing social support to women who experience abuse during pregnancy; however, their true involvement in mitigating the impact of violence in the African setting needs further research.

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.

How does intimate partner violence affect condom and oral contraceptive Use in the United States?: A systematic review of the literature.

PubMed

Bergmann, Julie N; Stockman, Jamila K

2015-06-01

Intimate partner violence (IPV) is estimated to affect 25% of adult women in the United States alone. IPV directly impacts women's ability to use contraception, resulting in many of unintended pregnancies and STIs. This review examines the relationship between IPV and condom and oral contraceptive use within the United States at two levels: the female victim's perspective on barriers to condom and oral contraceptive use, in conjunction with experiencing IPV (Aim 1) and the male perpetrator's perspective regarding condom and oral contraceptive use (Aim 2). We systematically reviewed and synthesized all publications meeting the study criteria published since 1997. We aimed to categorize the results by emerging themes related to each study aim. We identified 42 studies that met our inclusion criteria. We found 37 studies that addressed Aim 1. Within this we identified three themes: violence resulting in reduced condom or oral contraceptive use (n=15); condom or oral contraceptive use negotiation (n=15); which we further categorized as IPV due to condom or oral contraceptive request, perceived violence (or fear) of IPV resulting in decreased condom or oral contraceptive use, and sexual relationship power imbalances decreasing the ability to use condoms or oral contraceptives; and reproductive coercion (n=7). We found 5 studies that addressed Aim 2. Most studies were cross-sectional, limiting the ability to determine causality between IPV and condom or oral contraceptive use; however, most studies did find a positive relationship between IPV and decreased condom or oral contraceptive use. Quantitative, qualitative, and mixed methods research has demonstrated the linkages between female IPV victimization/male IPV perpetration and condom or oral contraceptive use. However, additional qualitative and longitudinal research is needed to improve the understanding of dynamics in relationships with IPV and determine causality between IPV, intermediate variables (e.g., contraceptive use negotiation, sexual relationship power dynamics, reproductive coercion), and condom and oral contraceptive use. Assessing the relationship between IPV and reproductive coercion may elucidate barriers to contraceptive use as well as opportunities for interventions to increase contraceptive use (such as forms of contraception with less partner influence) and reduce IPV and reproductive coercion.

Background Intimate partner violence (IPV) is common during pregnancy and the postpartum. Perinatal home visitation provides favorable conditions in which to identify and support women affected by IPV. However, the use of mHealth for delivering IPV interventions in perinatal home visiting has not been explored. Objective Our objective was to conduct a nested qualitative interpretive study to explore perinatal home visitors’ and women’s perceptions and experiences of the Domestic Violence Enhanced Home Visitation Program (DOVE) using mHealth technology (ie, a computer tablet) or a home visitor-administered, paper-based method. Methods We used purposive sampling, using maximum variation, to select women enrolled in a US-based randomized controlled trial of the DOVE intervention for semistructured interviews. Selection criteria were discussed with the trial research team and 32 women were invited to participate. We invited 45 home visitors at the 8 study sites to participate in an interview, along with the 2 DOVE program designers. Nonparticipant observations of home visits with trial participants who chose not to participate in semistructured interviews were undertaken. Results We conducted 51 interviews with 26 women, 23 home visiting staff at rural and urban sites, and the 2 DOVE program designers. We conducted 4 nonparticipant observations. Among 18 IPV-positive women, 7 used the computer tablet and 11 used the home visitor method. Among 8 IPV-negative women, 7 used the home visitor method. The computer tablet was viewed as a safe and confidential way for abused women to disclose their experiences without fear of being judged. The meanings that the DOVE technology held for home visitors and women led to its construction as either an impersonal artifact that was an impediment to discussion of IPV or a conduit through which interpersonal connection could be deepened, thereby facilitating discussion about IPV. Women’s and home visitors’ comfort with either method of screening was positively influenced by factors such as having established trust and rapport, as well as good interpersonal communication. The technology helped reduce the anticipated stigma associated with disclosing abuse. The didactic intervention video was a limiting feature, as the content could not be tailored to accommodate the fluidity of women’s circumstances. Conclusions Users and developers of technology-based IPV interventions need to consider the context in which they are being embedded and the importance of the patient-provider relationship in promoting behavior change in order to realize the full benefits. An mHealth approach can and should be used as a tool for initiating discussion about IPV, assisting women in enhancing their safety and exploring help-seeking options. However, training for home visitors is required to ensure that a computer tablet is used to complement and enhance the therapeutic relationship.

Although research has shown links between family-of-origin violence (FOV), intimate partner violence (IPV), and hostility, research has not examined whether hostility mediates the relationship between FOV and IPV. The current study examined whether hostility mediates FOV and IPV perpetration in 302 men arrested for domestic violence. Results demonstrated that hostility fully mediated the relationship between father-to-participant FOV and physical and psychological IPV and the relationship between mother-to-participant FOV and physical IPV. Results indicated that hostility fully mediated the relationship between experiencing and witnessing FOV and physical IPV (composite FOV), and partially mediated the relationship between composite FOV and psychological aggression.

Addressing substance abuse and violence in substance use disorder treatment and batterer intervention programs.

2012-09-07

Substance use disorders and perpetration of intimate partner violence (IPV) are interrelated, major public health problems. We surveyed directors of a sample of substance use disorder treatment programs (SUDPs; N=241) and batterer intervention programs (BIPs; N=235) in California (70% response rate) to examine the extent to which SUDPs address IPV, and BIPs address substance abuse. Generally, SUDPs were not addressing co-occurring IPV perpetration in a formal and comprehensive way. Few had a policy requiring assessment of potential clients, or monitoring of admitted clients, for violence perpetration; almost one-quarter did not admit potential clients who had perpetrated IPV, and only 20% had a component or track to address violence. About one-third suspended or terminated clients engaging in violence. The most common barriers to SUDPs providing IPV services were that violence prevention was not part of the program's mission, staff lacked training in violence, and the lack of reimbursement mechanisms for such services. In contrast, BIPs tended to address substance abuse in a more formal and comprehensive way; e.g., one-half had a policy requiring potential clients to be assessed, two-thirds required monitoring of substance abuse among admitted clients, and almost one-half had a component or track to address substance abuse. SUDPs had clients with fewer resources (marriage, employment, income, housing), and more severe problems (both alcohol and drug use disorders, dual substance use and other mental health disorders, HIV + status). We found little evidence that services are centralized for individuals with both substance abuse and violence problems, even though most SUDP and BIP directors agreed that help for both problems should be obtained simultaneously in separate programs. SUDPs may have difficulty addressing violence because they have a clientele with relatively few resources and more complex psychological and medical needs. However, policy change can modify barriers to treatment integration and service linkage, such as reimbursement restrictions and lack of staff training.

The impact of intimate partner violence on women's reproductive health and pregnancy outcome.

Sarkar, N N

2008-04-01

The aim of this study was to evaluate and elucidate the impact of intimate partner violence (IPV) on women's reproductive health and pregnancy outcomes taking into account data from various countries. The search of the literature was made in MEDLINE database service for the years 2002-2008. Original articles, reviews, surveys, clinical trials and investigations pertinent to the theme were considered for this review. The lifetime physical or sexual IPV or both varied from 15% to 71% in many countries. Adolescent violence, negative emotionality and quality of the relationship with the intimate partner were associated with genesis of IPV, besides demographic, social and structural difference in attitudes. IPV affected woman's physical and mental health, reduced sexual autonomy, increased risk for unintended pregnancy and multiple abortions. Risk for sexual assault decreased by 59% or 70% for women contacting the police or applying for a protection order, respectively. Quality of life of IPV victims was found significantly impaired. Women battered by IPV reported high levels of anxiety and depression that often led to alcohol and drug abuse. Violence on pregnant women significantly increased risk for low birth weight infants, pre-term delivery and neonatal death and also affected breast-feeding postpartum. Women preferred an active role to be played by healthcare providers in response to IPV disclosure. Gynaecologists reported interventions for the patient disclosing IPV and provided treatment for their physical and emotional complaints. Educating and empowering women and upgrading their socioeconomic status may abate the incidence of IPV. Women should also seek protection against IPV.

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

Sutherland, Melissa A; Hutchinson, M Katherine

2018-02-01

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.

Risk factors for intimate partner violence in women in the Rakai Community Cohort Study, Uganda, from 2000 to 2009

PubMed Central

2013-01-01

Background Intimate partner violence (IPV) is a significant public health problem. There is a lack of data on IPV risk factors from longitudinal studies and from low and middle income countries. Identifying risk factors is needed to inform the design of appropriate IPV interventions. Methods Data were from the Rakai Community Cohort Study annual surveys between 2000 and 2009. Female participants who had at least one sexual partner during this period and had data on IPV over the study period were included in analyses (N = 15081). Factors from childhood and early adulthood as well as contemporary factors were considered in separate models. Logistic regression was used to assess early risk factors for IPV during the study period. Longitudinal data analysis was used to assess contemporary risk factors in the past year for IPV in the current year, using a population-averaged multivariable logistic regression model. Results Risk factors for IPV from childhood and early adulthood included sexual abuse in childhood or adolescence, earlier age at first sex, lower levels of education, and forced first sex. Contemporary risk factors included younger age, being married, relationships of shorter duration, having a partner who is the same age or younger, alcohol use before sex by women and by their partners, and thinking that violence is acceptable. HIV infection and pregnancy were not associated with an increased odds of IPV. Conclusions Using longitudinal data, this study identified a number of risk factors for IPV. These findings are useful for the development of prevention strategies to prevent and mitigate IPV in women. PMID:23759123

Intimate partner violence among men and women who use methamphetamine: A mixed-methods study in South Africa

Introduction The prevalence of methamphetamine use has risen dramatically in parts of South Africa. Globally, methamphetamine has been linked to intimate partner violence (IPV) and other forms of aggression. The aim of this mixed-methods study was to examine the experiences of physical IPV and its contextual factors among methamphetamine users in an urban community in Cape Town, South Africa. Methods Active methamphetamine users were recruited using respondent driven sampling. All participants (n=360) completed structured surveys, and a subset (n=30) completed in-depth interviews with discussions of personal IPV experiences. Quantitative data were examined separately by gender, and regression models were used to identify factors that were associated with physical IPV victimisation and perpetration. Qualitative data were analysed to provide contextual understanding. Results In the past 3 months, 47% of women and 31% of men reported being a victim of IPV, and 30% of women and 28% men reported being a perpetrator of IPV. Victimisation and perpetration were highly correlated, and both were significantly associated with histories of other traumas. Although the survey data suggests gender equivalence in IPV, the qualitative data provides a more nuanced context, with female victimisation by male partners being particularly frequent and intense. In narratives, IPV was a product of male aggression while using methamphetamine, norms around sex trading, and gender-based attitudes endorsing violence against women. Conclusion Addiction to methamphetamine creates heightened risks of IPV, especially among those with previous traumas. The findings emphasise the importance of identifying and addressing IPV among methamphetamine users in South Africa. PMID:27246967

Children in homes with intimate partner violence (IPV) are at increased risk for physical abuse. We determined the frequency and injury patterns in children who underwent child abuse consultation after IPV exposure by retrospectively analyzing the "Examination of Siblings To Recognize Abuse" cohort of children referred for physical abuse. Children were selected who presented after IPV exposure. Among 2890 children evaluated by child abuse pediatricians, 61 (2.1%) patients presented after IPV exposure. Of the 61, 11 (18.0%) were exposed to IPV, but had no direct involvement in the IPV event, 36 (59.0%) sustained inadvertent trauma during IPV, and 14 (23.0%) were directly assaulted during IPV. Thirty-six patients (59.0%) had an injury: 31 (51.0%) had cutaneous injuries and 15 (24.6%) had internal injuries including fracture(s), intracranial or intra-abdominal injury. Of the 15 patients with internal injuries, 14 (93.3%) were less than 12 months old. Among the 36 patients with injuries, 16 (44.4%) had no report of direct injury, a report of a mechanism that did not explain the identified injuries, or a report of trauma without a specific mechanism. Five (13.9%) did not have physical examination findings to suggest the extent of their internal injuries. Injuries are present in a significant proportion of children presenting to Emergency Departments after IPV exposure. History and physical examination alone are insufficient to detect internal injuries especially in infants. These preliminary results support the need for future, prospective studies of occult injury in children exposed to IPV. Copyright © 2018 Elsevier Ltd. All rights reserved.

Rapid urbanization is a key driver of the unique set of health risks facing urban populations. One of the most critical health hazards facing urban women is intimate partner violence (IPV). In post-conflict urban areas, women may face an even greater risk of IPV. Yet, few studies have examined the IPV experiences of urban-dwelling, conflict-affected women, including those who have been internally displaced. This study qualitatively examined the social and structural characteristics of the urban environment that contributed to the IPV experiences of women residing in post-conflict Abidjan, Côte d'Ivoire. Ten focus groups were conducted with men and women, both internally displaced (IDPs) and non-displaced. Lack of support networks, changing gender roles, and tensions between traditional gender norms and those of the "modern" city were reported as key contributors to IPV. Urban poverty and with it unemployment, food insecurity, and housing instability also played a role. Finally, IDPs faced heightened vulnerability to IPV as a result of displacement and discrimination. The relationship between economic strains and IPV are similar to other conflict-affected settings, but Abidjan's urban environment presented other unique characteristics contributing to IPV. Understanding these factors is crucial to designing appropriate services for women and for implementing IPV reduction interventions in urban areas. Strengthening formal and informal mechanisms for help-seeking, utilizing multi-modal interventions that address economic stress and challenge inequitable gender norms, as well as tailoring programs specifically for IDPs, are some considerations for IPV program planning focused on conflict-affected women in urban areas.

This study has been carried out in order to explore the effect of the growing appearance of IPV in television news items on deaths by this cause. Ecological study based on 340 deaths by intimate partner violence (IPV) and 3733 television news items covering this topic on Spanish television channels (2003 and 2007). Logistic regression analysis was carried out. Dependent variable: the difference between the number of IPV deaths in the 7 days following a news item broadcast and the number of IPV deaths in the 7 days before a media item. This outcome variable was conceptualised as a binary variable: increase vs. no increase. days with IPV news items-in general, concerning deaths, measures or other IPV crimes. Adjusted variables: day of the week, month, year and public holidays. A small copycat effect was observed in the IPV murder rate (RR = 1.32, CI(95%) = 1.07 - 1.62) for IPV-related news item days compared with days without such news. This effect continued when information about deaths was broadcast (RR = 1.28, CI(95%) = 1.01 - 1.62). News items concerning measures (RR = 0.90, CI(95%) = 0.82 - 0.98) or other IPV crimes (0.84, CI(95%) = 0.82 - 0.98) were related to a lower possibility of an increase in deaths compared with days with death-related news. Given the results observed in the case of IPV-related news, there is an evident need to develop a journalistic style guide in order to determine what type of information is recommended due to the potential positive or negative effects.

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.

The purpose of this study was to conduct a baseline assessment of intimate partner violence (IPV) practices in a pediatric hospital system. The Delphi Instrument for Hospital-based Domestic Violence Programs was used to assess the structure and components of the hospital system's IPV practices. Through key stakeholder interviews, we also assessed IPV practices in individual patient care areas. Qualitative analysis of interview data used a grounded theory approach. The hospital scored 17 of 100 points on the Delphi instrument assessment. Key areas of weakness identified by the Delphi instrument and interviews included lack of coordinated provider training and evaluation of IPV-related processes and no standards for IPV screening, safety assessment, and documentation. Most interviewees supported addressing IPV; all identified barriers to IPV screening at individual provider and institutional levels. Institutional barriers included lack of a standardized response to IPV disclosure, need for individualized screening protocols for different patient care settings, lack of standardized provider training, concerns about overextending social work resources, and lack of resources for hospital staff experiencing vicarious trauma. Individual barriers included concern that screening may harm physician-patient-family relationships and the perception that physicians are unwilling to address psychosocial issues. The Delphi Instrument for Hospital-based Domestic Violence Programs identified weaknesses and key areas for improvement in IPV practices. Deficiencies revealed by the Delphi instrument were affirmed by individual interview results. Institutional and individual provider level barriers must be addressed to optimize IPV practices in a pediatric hospital system. Copyright © 2015 by the American Academy of Pediatrics.

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.

Childhood family violence exposure is associated with increased risk for experiencing intimate partner violence (IPV) in adulthood, but the mechanisms underlying this relationship remain inadequately understood. Difficulties with emotion regulation may be one factor that helps to explain this relationship. Childhood physical abuse and interparental violence, as well as subsequent IPV experiences, were assessed in a large sample of young adults (N = 670). Several indicators of anger-related dysregulation were also assessed. Structural equation modeling was used to create a latent variable of anger-related dysregulation, which was examined as a potential mediator of the associations between childhood family violence exposure and IPV. Childhood physical abuse and interparental violence were associated with greater physical, sexual, and emotional IPV victimization. Childhood physical abuse and interparental violence were also associated with anger-related dysregulation, which was positively associated with all three types of IPV experiences. Anger-related dysregulation fully mediated the association between witnessing interparental violence and physical IPV. Anger-related dysregulation partially mediated the association between witnessing interparental violence and psychological IPV and the associations of childhood physical abuse with all three forms of IPV. These associations were consistent across gender. Interventions aimed at reducing IPV risk among survivors of childhood family violence may benefit from including techniques to target anger-related emotion regulation skills.

Kano State, Nigeria, introduced inactivated polio vaccine (IPV) into its routine immunization (RI) schedule in March 2015 and was the pilot site for an RI data module for the National Health Management Information System (NHMIS). We determined factors impacting IPV introduction and the value of the RI module on monitoring new vaccine introduction. Two assessment approaches were used: (1) analysis of IPV vaccinations reported in NHMIS, and (2) survey of 20 local government areas (LGAs) and 60 associated health facilities (HF). By April 2015, 66% of LGAs had at least 20% of HFs administering IPV, by June all LGAs had HFs administering IPV and by July, 91% of the HFs in Kano reported administering IPV. Among surveyed staff, most rated training and implementation as successful. Among HFs, 97% had updated RI reporting tools, although only 50% had updated microplans. Challenges among HFs included: IPV shortages (20%), hesitancy to administer 2 injectable vaccines (28%), lack of knowledge on multi-dose vial policy (30%) and age of IPV administration (8%). The introduction of IPV was largely successful in Kano and the RI module was effective in monitoring progress, although certain gaps were noted, which should be used to inform plans for future vaccine introductions. © The Author 2017.

2018-03-01

Workplace bullying (WB) is an increasingly prevalent topic in the nursing literature. Recently, a new concept has been introduced into WB research to explain the motivations of WB instigators using elements of the Power-Control Wheel (PCW). Initially, this wheel was designed to assist intimate partner violence (IPV) targets/victims identify patterns of abuse and intervene with male batterers/instigators. Research examining IPV and victims/survivors of WB demonstrate that targets often share common abusive experiences, including intimidation, coercion and threats, isolation, and economic and emotional abuse. This article demonstrates clear support for the Duluth Model and its application to WB target experiences. Applications of this model to identify WB and assist individuals to identify and describe experiences of abusive work environments are discussed.

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

PubMed

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.

Masculine Discrepancy Stress, Emotion-Regulation Difficulties, and Intimate Partner Violence

Research suggests that masculine socialization processes contribute to the perpetration of intimate partner violence (IPV) by men. Although this research has traditionally focused on men who strongly adhere to traditional gender norms, men who negatively evaluate themselves as falling short of these norms (a construct termed masculine discrepancy stress) have proven to be at increased risk of IPV perpetration. Likewise, men experiencing problems with emotion regulation, a multidimensional construct reflecting difficulties in effectively experiencing and responding to emotional states, are also at risk of IPV perpetration. In the present research, we tested the hypothesis that the link between discrepancy stress and IPV perpetration is mediated via difficulties in emotion regulation. Three hundred fifty-seven men completed online surveys assessing their experience of discrepancy stress, emotion-regulation difficulties, and history of IPV perpetration. Results indicated that discrepancy-stressed men's use of physical IPV was fully mediated by emotion-regulation difficulties. In addition, emotion-regulation difficulties partially mediated the association between discrepancy stress and sexual IPV. Findings are discussed in terms of the potential utility of emotion-focused interventions for modifying men's experience and expression of discrepancy stress and reducing perpetration of IPV.

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 the Sabin-IPV was evaluated in a double-blind, randomized, controlled, phase I 'proof-of-concept' trial. Healthy male adults received a single intramuscular injection with Sabin-IPV, Sabin-IPV adjuvanted with aluminum hydroxide or conventional IPV. Virus-neutralizing titers against both Sabin and wild poliovirus strains were determined before and 28 days after vaccination. No vaccine-related serious adverse events were observed, and all local and systemic reactions were mild or moderate and transient. In all subjects, an increase in antibody titer for all types of poliovirus (both Sabin and wild strains) was observed 28 days after vaccination. Sabin-IPV and Sabin-IPV adjuvanted with aluminum hydroxide administered as a booster dose were equally immunogenic and safe as conventional IPV. EudraCTnr: 2010-024581-22, NCT01708720.

This study describes the associations between intimate partner violence (IPV) and HIV risk among urban, predominantly minority women. Interviews were conducted with 1,590 women, predominantly African American and Latina, attending hospital-based health care clinics. Approximately 1 in 5 women reported experiencing IPV in their current primary heterosexual relationships; about 1 in 8 women reported experiencing IPV in the preceding 6 months. Compared to women who reported no IPV in their primary relationships, women reporting past or current IPV perpetrated by their primary partners were more likely to report having multiple sexual partners, a past or current sexually transmitted infection (STI), inconsistent use or nonuse of condoms, and a partner with known HIV risk factors. These findings indicate that urban minority women experiencing IPV are at elevated risk for HIV infection, results that carry important implications in the efforts to improve HIV and IPV risk assessment protocols and intervention/prevention strategies for women in primary health care settings.

Understanding the Use of Violence Among Men Who Sustain Intimate Terrorism

PubMed Central

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

The hypothesis that the disinhibitory effects induced by alcohol consumption contribute to domestic violence has gained support from meta-analyses of mainly cross-sectional studies that examined the association between alcohol abuse and perpetration of intimate partner violence (IPV). However, findings from multilevel analyses of longitudinal data investigating the time-varying effects of heavy episodic drinking (HED) on physical IPV have been equivocal. This 12-year prospective study used multilevel analysis to examine the effects of HED and illicit drug use on perpetration of both physical and psychological IPV during early adulthood. Participants were 157 romantic couples who were assessed biennially 2 to 6 times for substance misuse and IPV. The analyses found no significant main effect of either HED or drug use on perpetration of IPV but there were significant interactions of both HED and drug use with age. Moreover, the developmental trends in substance use effects on IPV typically varied by gender and type of IPV. PMID:25678737

2014-08-01

Intimate partner violence (IPV) is a significant health issue faced by women veterans, but little is known about their preferences for IPV-related care. Five focus groups were conducted with 24 women Veterans Health Administration (VHA) patients with and without a lifetime history of IPV to understand their attitudes and preferences regarding IPV screening and responses within VHA. Women veterans wanted disclosure options, follow-up support, transparency in documentation, and VHA and community resources. They supported routine screening for IPV and articulated preferences for procedural aspects of screening. Women suggested that these procedures could be provided most effectively when delivered with sensitivity and connectedness. Findings can inform the development of IPV screening and response programs within VHA and other healthcare settings. © 2014 Wiley Periodicals, Inc.

Employee Assistance Programs (EAPs) are workplace resources available to employees with problems impacting work performance. EAPs are well-positioned to address intimate partner violence (IPV), a major public health problem with workplace impacts. A purposeful sample of 28 EAPs across the United States was surveyed to identify policies and programs to address IPV, including perpetration. Most EAPs did not report having standardized approaches for addressing IPV perpetration. EAPs also described significant barriers to identifying IPV perpetrators, with the majority relying on self-disclosure on the part of the perpetrator when contacting the EAP. These results suggest that many EAPs--even when interacting with employees who present with issues known to correlate with IPV--are missing a potential opportunity to assess and intervene with IPV perpetrators.

Following the proposed worldwide switch from trivalent oral poliovirus vaccine (tOPV) to bivalent types 1 and 3 OPV (bOPV) in 2016, inactivated poliovirus vaccine (IPV) will be the only source of protection against poliovirus type 2. With most countries opting for one dose of IPV in routine immunisation schedules during this transition because of cost and manufacturing constraints, optimisation of protection against all poliovirus types will be a priority of the global eradication programme. We assessed the immunogenicity and safety of a novel monovalent high-dose inactivated poliovirus type 2 vaccine (mIPV2HD) in infants. This observer-blind, comparative, randomised controlled trial was done in a single centre in Panama. We enrolled healthy infants who had not received any previous vaccination against poliovirus. Infants were randomly assigned (1:1) by computer-generated randomisation sequence to receive a single dose of either mIPV2HD or standard trivalent IPV given concurrently with a third dose of bOPV at 14 weeks of age. At 18 weeks, all infants were challenged with one dose of monovalent type 2 OPV (mOPV2). Primary endpoints were seroconversion and median antibody titres to type 2 poliovirus 4 weeks after vaccination with mIPV2HD or IPV; and safety (as determined by the proportion and nature of serious adverse events and important medical events for 8 weeks after vaccination). The primary immunogenicity analyses included all participants for whom a post-vaccination blood sample was available. All randomised participants were included in the safety analyses. This trial is registered with ClinicalTrials.gov, number NCT02111135. Between April 14 and May 9, 2014, 233 children were enrolled and randomly assigned to receive mIPV2HD (117 infants) or IPV (116 infants). 4 weeks after vaccination with mIPV2HD or IPV, seroconversion to poliovirus type 2 was recorded in 107 (93·0%, 95% CI 86·8-96·9) of 115 infants in the mIPV2HD group compared with 86 (74·8%, 65·8-82·4) of 115 infants in the IPV group (difference between groups 18·3%, 95% CI 5·0-31·1; p<0·0001), and median antibody titres against poliovirus type 2 were 181 (95% CI 72·0-362·0) in the mIPV2HD group and 36 (18·0-113·8) in the IPV group (difference between groups 98·8, 95% CI 60·7-136·9; p<0·0001). Serious adverse events were reported for six (5%) of 117 infants in the mIPV2HD group and seven (6%) of 116 infants in the IPV group during the 8-week period after vaccination; none were related to vaccination. No important medical events were reported. Our findings lend support to the use of mIPV2HD as an option for stockpiling for outbreak response or primary protection in selected areas at risk for emergence of poliovirus type 2 during the next phase of the polio eradication plan.

A breakthrough in the LEO cycle life of individual pressure vessel (IPV) nickel-hydrogen cells has been previously reported. The cycle life of boiler plate cells containing 26 percent potassium hydroxide (KOH) electrolyte was about 40,000 LEO cycles, compared to 3500 cycles for cells containing 31 percent KOH. The cycle regime was a stressful accelerated LEO, which consisted of a 27.5 min charge followed by a 17.5 min discharge (2X normal rate). The depth-of-discharge was 80 percent. Six 48-Ah Hughes recirculation design IPV nickel-hydrogen flight battery cells are being evaluated. Three of the cells contain 26 percent KOH (test cells), and three contain 31 percent KOH (control cells). They are undergoing real time LEO cycle life testing. The cycle regime is a 90-min LEO orbit consisting of a 54-min charge followed by a 36-min discharge. The depth-of-discharge is 80 percent. The cell temperature is maintained at 10 C. The three 31 percent KOH cells failed (cycles 3729, 4165, and 11355). One of the 26 percent KOH cells failed at cycle 15314. The other two 26 percent KOH cells were cycled for over 16,000 cycles during the continuing test.

Changes in children's emotion differentiation, coping skills, parenting stress, parental psychopathology, and parent-child interaction were explored as mediators of treatment factors in two selective preventive group interventions for children exposed to interparental violence (IPV) and their parents. One hundred thirty-four IPV-exposed children (ages 6-12 years, 52% boys) and their parents were randomized to an IPV-focused or common factors community-based group intervention and completed baseline, posttest, and follow-up assessments for posttraumatic stress (PTS). A multilevel model tested mediators that included children's ability to differentiate emotions and coping skills, parenting stress, parental psychopathology, and parent-child interactions. In both conditions, exposure to nonspecific factors, specific factors unrelated to IPV and trauma-specific intervention factors was coded from videotaped child and parent sessions. Improved parental mental health mediated the link between greater exposure to nonspecific treatment factors and decreases in PTS symptoms. In addition, an increase in emotion differentiation and a decrease in parenting stress were associated with a decrease in PTS symptoms. Greater exposure to trauma-specific factors in child sessions was associated with a small decrease in emotion differentiation, an increase in coping skills, and a decrease in PTS symptoms over time. Greater exposure to nonspecific treatment factors in child and parent sessions was associated with more positive parent-child interaction. Parental mental health appears to be an important mechanism of change that can be promoted through exposure to nonspecific factors in parent intervention. For children, the effect of greater exposure to trauma-specific factors in intervention is less clear and may not have clear benefits.

Intimate Partner Violence (IPV) is the most common form of violence in conflict and post-conflict settings, but there are few evaluations of interventions to prevent IPV in such settings. The Women for Women International (WfWI) intervention is a year-long combined economic and social empowerment intervention for marginalized women survivors of conflict. Primarily, it seeks to support women to achieve four key outcomes: women earn and save money; women improve their health and well-being; women influence decisions in their homes and communities; women connect to networks for support. The organization recognizes Violence Against Women and Girls (VAWG) as a significant barrier to women's empowerment and expects to see reduction in VAWG, and specifically IPV, as part of building women's social and economic empowerment. This program is being quantitatively evaluated through an individually randomized control trial amongst women in Afghanistan, with a 24-month follow up. A comparison of baseline characteristics of participants is also included as well as a discussion of implementation of the baseline research. There is a high demand amongst Afghan women for such interventions, and this posed challenges in completing the randomization and baseline. In addition, the complex security situation in Afghanistan also posed challenges. However, despite these issues, recruitment was successfully achieved and the arms were balanced on socio-demographic measures. The evaluation will contribute to the limited evidence base on interventions to prevent IPV in conflict-affected settings. NCT03236948 . Registered 28 July 2017, retrospectively registered.

Concomitant administration of bivalent rLP2086 (Trumenba [Pfizer, Inc] and diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine (DTaP/IPV) was immunologically noninferior to DTaP/IPV and saline and was safe and well tolerated. Bivalent rLP2086 elicited robust and broad bactericidal antibody responses to diverse Neisseria meningitidis serogroup B strains expressing antigens heterologous to vaccine antigens after 2 and 3 vaccinations. Bivalent rLP2086, a Neisseria meningitidis serogroup B (MnB) vaccine (Trumenba [Pfizer, Inc]) recently approved in the United States to prevent invasive MnB disease in individuals aged 10-25 years, contains recombinant subfamily A and B factor H binding proteins (fHBPs). This study evaluated the coadministration of Repevax (diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine [DTaP/IPV]) (Sanofi Pasteur MSD, Ltd) and bivalent rLP2086. Healthy adolescents aged ≥11 to <19 years received bivalent rLP2086 + DTaP/IPV or saline + DTaP/IPV at month 0 and bivalent rLP2086 or saline at months 2 and 6. The primary end point was the proportion of participants in whom prespecified levels of antibodies to DTaP/IPV were achieved 1 month after DTaP/IPV administration. Immune responses to bivalent rLP2086 were measured with serum bactericidal assays using human complement (hSBAs) against 4 MnB test strains expressing fHBP subfamily A or B proteins different from the vaccine antigens. Participants were randomly assigned to receive bivalent rLP2086 + DTaP/IPV (n = 373) or saline + DTaP/IPV (n = 376). Immune responses to DTaP/IPV in participants who received bivalent rLP2086 + DTaP/IPV were noninferior to those in participants who received saline + DTaP/IPV.The proportions of bivalent rLP2086 + DTaP/IPV recipients with prespecified seroprotective hSBA titers to the 4 MnB test strains were 55.5%-97.3% after vaccination 2 and 81.5%-100% after vaccination 3. The administration of bivalent rLP2086 was well tolerated and resulted in few serious adverse events. Immune responses to DTaP/IPV administered with bivalent rLP2086 to adolescents were noninferior to DTaP/IPV administered alone. Bivalent rLP2086 was well tolerated and elicited substantial and broad bactericidal responses to diverse MnB strains in a high proportion of recipients after 2 vaccinations, and these responses were further enhanced after 3 vaccinations.ClinicalTrials.gov identifier NCT01323270. © The Author 2016.

Intimate partner violence (IPV) during pregnancy can have serious health consequences for mothers and newborns. The aim of the study is to explore: 1) the influence of experiencing IPV during pregnancy on delayed entry into prenatal care; and 2) whether women's decision-making autonomy and the support for traditional gender roles act to mediate or moderate the relationship between IPV and delayed entry into prenatal care. cross-sectional survey. Multivariate logistic regression models were estimated that control for various socio-demographic and pregnancy related factors to assess whether women who experienced IPV during pregnancy were more likely to delay entry into prenatal care compared with women who had not experienced IPV. The influence of traditional gender roles acceptance and decision-making autonomy were examined both as independent variables and in interaction with IPV, to assess their role as potential mediators or moderators. Chandpur district, Bangladesh. the sample comprised of 426 Bangladeshi women, aged 15-49 years. Postpartum mothers who visited vaccinations centres to receive their children's vaccinations constitute the sampling frame. almost 70% of the women surveyed reported patterns consistent with delayed entry into prenatal care. Accounting for the influence of other covariates, women who experienced physical IPV during pregnancy were 2.61 times more likely (95% CI [1.33, 5.09]) to have delayed entry into prenatal care than their counterparts who did not report physical IPV. Neither sexual nor psychological IPV victimization during pregnancy was linked with late entry into prenatal care. Both gender role attitudes and levels of autonomy mediate the effect of IPV on prenatal care. the results suggest that the high rates of IPV in Bangladesh have effects that can compromise women's health seeking behaviour during pregnancy, putting them and their developing fetus at risk. Specifically, Bangladeshi women who experience physical IPV during pregnancy are more likely to delay or forgo prenatal care, an effect that is further magnified by cultural ideals that emphasize women's traditional roles and limit their autonomy. this study reinforces the need to detect and assist women suffering IPV, not only to offer them help and support but also to increase entry into prenatal care. Healthcare professionals involved in obstetrics and midwifery need to be aware of the risk factors of IPV during pregnancy and be able to identify women who are at risk for delayed entry into prenatal care.

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.

Cross-sectional prevalence survey of intimate partner violence perpetration and victimization in Canadian military personnel

PubMed Central

2013-01-01

Background Intimate partner violence (IPV) is prevalent and is associated with a broad range of adverse consequences. In military organizations, IPV may have special implications, such as the potential of service-related mental disorders to trigger IPV. However, the Canadian Armed Forces (CAF) have limited data to guide their prevention and control efforts. Methods Self-reported IPV perpetration, victimization, and their correlates were assessed on a cross-sectional survey of a stratified random sample of currently-serving Canadian Regular Forces personnel (N = 2157). The four primary outcomes were perpetration or victimization of any physical and/or sexual or emotional and/or financial IPV over the lifespan of the current relationship. Results Among the 81% of the population in a current relationship, perpetration of any physical and/or sexual IPV was reported in 9%; victimization was reported in 15%. Any emotional and/or financial abuse was reported by 19% (perpetration) and 22% (victimization). Less physically injurious forms of abuse predominated. Logistic regression modelling showed that relationship dissatisfaction was independently associated with all four outcomes (OR range = 2.3 to 3.7). Probable depression was associated with all outcomes except physical and/or sexual IPV victimization (OR range = 2.5 – 2.7). PTSD symptoms were only associated with physical and/or sexual IPV perpetration (OR = 3.2, CI = 1.4 to 7.9). High-risk drinking was associated with emotional and/or financial abuse. Risk of IPV was lowest in those who had recent deployment experience; remote deployment experience (vs. never having deployed) was an independent risk factor for all IPV outcomes (OR range = 2.0 – 3.4). Conclusions IPV affects an important minority of military families; less severe cases predominate. Mental disorders, high-risk drinking, relationship dissatisfaction, and remote deployment were independently associated with abuse outcomes. The primary limitations of this analysis are its use of self-report data from military personnel (not their intimate partners) and the cross-sectional nature of the survey. Prevention efforts in the CAF need to target the full spectrum of IPV. Mental disorders, high-risk drinking, and relationship dissatisfaction are potential targets for risk reduction. Additional research is needed to understand the association of remote deployment with IPV. PMID:24165440

Background Violence against females is a widespread public health problem in Turkey and the lifetime prevalence of IPV ranges between 34 and 58.7%. Health care workers (HCW) sometimes have the unique opportunity and obligation to identify, treat, and educate females who are abused. The objective of this study was to evaluate the knowledge, attitudes, and experiences of the emergency department (ED) staff regarding intimate partner violence (IPV) at a large university hospital in Turkey. Methods A cross-sectional study was conducted in a large university hospital via questionnaire. The study population consisted of all the nurses and physicians who worked in the ED during a two month period (n = 215). The questionnaire response rate was 80.5% (41 nurses and 132 physicians). The main domains of the questionnaire were knowledge regarding the definition of IPV, clinical findings in victims of IPV, legal aspects of IPV, attitudes towards IPV, knowledge about the characteristics of IPV victims and abusers, and professional and personal experiences and training with respect to IPV. Results One-half of the study group were females, 76.3% were physicians, and 89.8% had no training on IPV. The majority of the nurses (89.5%) and physicians (71.1%) declared that they were aware of the clinical appearance of IPV. The mean of the knowledge scores on clinical knowledge were 8.84 ± 1.73 (range, 0–10) for acute conditions, and 4.51 ± 3.32 for chronic conditions. The mean of the knowledge score on legal procedures and the legal rights of the victims was 4.33 ± 1.66 (range, 0–7). At least one reason to justify physical violence was accepted by 69.0% of females and 84.7% of males, but more males than females tended to justify violence (chi square = 5.96; p = 0.015). However, both genders accepted that females who experienced physical violence should seek professional medical help. Conclusion The study participants' knowledge about IPV was rather low and a training program is thus necessary on this issue. Attention must be given to the legal aspects and clinical manifestations of IPV. The training program should also include a module on gender roles in order to improve the attitudes towards IPV.

To evaluate the immunogenicity and safety of a reduced antigen diphtheria-tetanus-acellular pertussis-inactivated poliovirus (dTap-IPV B ) vaccine (Boostrix-IPV, GSK) as a pre-school booster in 3-4 year old children as compared to dTap-IPV R (Repevax, Sanofi Pasteur), when co-administered with mumps-measles-rubella vaccine (MMRV). This phase III, open label, randomised study was conducted in the UK between April 2011 and April 2012. Children due their pre-school dTap-IPV booster vaccination were randomised 2:1 to receive one of two different dTap-IPV vaccines (dTap-IPV B or dTap-IPV R ) with blood sample for immunogenicity assessment just prior and one month after vaccination. Immune responses to diphtheria, tetanus and polio antigens were compared between the study vaccines (inferential comparison). In the absence of an accepted pertussis correlate of protection, the immunogenicity of dTap-IPV B vaccine against pertussis was compared with historical pertussis efficacy data (inferential comparison). Safety and reactogenicity of both study vaccines were evaluated. 387 children were randomised and 385 vaccinated: 255 in the dTap-IPV B group and 130 in the dTap-IPV R group. Prior to vaccination, ≥76.8% of children had anti-diphtheria and ≥65.5% had anti-tetanus titres above the protection threshold; for pertussis, the pre-vaccination seropositivity rate ranged between 18.1 and 70.6%. Both vaccines were immunogenic with 99.2-100% of children achieving titres above the pre-specified seroprotection/seropositivity thresholds. One serious adverse event not considered as causally related to the study vaccination by the study investigator was reported in the dTap-IPV B group. Non-inferiority of dTap-IPV B to dTap-IPV R was demonstrated. Both vaccines had a clinically acceptable safety and reactogenicity profile when co-administered with MMRV to children 3-4 years old.

The Economic Burden of Intimate Partner Violence in Ecuador: Setting the Agenda for Future Research and Violence Prevention Policies

PubMed Central

Corso, Phaedra

2013-01-01

Introduction: Intimate partner violence (IPV) is a widespread social structural problem that affects a great proportion of Ecuadorian women. IPV is a sexually, psychologically, or physically coercive act against an adult or adolescent woman by a current or former intimate partner. Not-for-profit groups in Ecuador report that 70% of women experience 1 of the forms of IPV sometime during their lifetime, but population-based surveys suggest that 41% of Ecuadorian women are exposed to emotional violence, 31% physical violence, and 12% sexual violence by their spouse or partner over their lifetime. Despite the high prevalence, the response of the Ecuadorian government has been insufficient to reduce the number of victims and to provide adequate legal and health services for the prevention and treatment of IPV. Given the power of economic data to influence policy making, the goal of this study is to produce the first estimate of the economic impact of IPV in Ecuador and to identify the policy paths in which these estimates would have the greatest impact for Ecuador. Methods: Using a bottom-up method for estimating the economic burden of IPV and a national prevalence of IPV based on a population-based survey in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 United States (U.S.) currency rate. Results: Based on a prevalence of 255,267 women who were victims of IPV in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 the U.S. currency rate. The largest cost category contributing to the economic burden was the costs of healthcare services to treat injuries associated with IPV events. Conclusion: The asymmetry between the economic burden of IPV and the amount of government resources devoted to IPV prevention efforts suggests the need for a greater role to be played by the government and other factors in society in the area of IPV prevention.

Estimating the Effect of Intimate Partner Violence on Women’s Use of Contraception: A Systematic Review and Meta-Analysis

2015-01-01

Background Intimate partner violence (IPV) is an important global public health problem. While there is a growing literature on the association between IPV and women’s reproductive health (RH) outcomes, most studies are cross-sectional—which weakens inference about the causal effect of IPV on women’s RH. This systematic review synthesizes existing evidence from the strongest study designs to estimate the impact of IPV on women’s use of contraception. Methods We searched 11 electronic databases from January of 1980 to 3 December 2013 and reviewed reference lists from systematic reviews for studies examining IPV and contraceptive use. To be able to infer causality, we limited our review to studies that had longitudinal measures of either IPV or women’s use of contraception. Results Of the 1,574 articles identified by the search, we included 179 articles in the full text review and extracted data from 12 studies that met our inclusion criteria. We limited the meta-analysis to seven studies that could be classified as subject to low or moderate levels of bias. Women’s experience of IPV was associated with a significant reduction in the odds of using contraception (n = 14,866; OR: 0.47; 95% CI: 0.25, 0.85; I2 = 92%; 95% CII2: 87%, 96%). Restricting to studies that measured the effect of IPV on women’s use of partner dependent contraceptive methods was associated with a reduction in the heterogeneity of the overall estimate. In the three studies that examined women’s likelihood of using male condoms with their partners, experience of IPV was associated with a significant decrease in condom use (OR: 0.48; 95% CIOR: 0.32, 0.72; I2 = 51%; 95% CII2: 0%, 86%). Conclusions IPV is associated with a reduction in women’s use of contraception; women who experience IPV are less likely to report using condoms with their male partners. Family planning and HIV prevention programs should consider women’s experiences of IPV. PMID:25693056

Depression and suicide are responsible for a substantial burden of disease globally. Evidence suggests that intimate partner violence (IPV) experience is associated with increased risk of depression, but also that people with mental disorders are at increased risk of violence. We aimed to investigate the extent to which IPV experience is associated with incident depression and suicide attempts, and vice versa, in both women and men. We conducted a systematic review and meta-analysis of longitudinal studies published before February 1, 2013. More than 22,000 records from 20 databases were searched for studies examining physical and/or sexual intimate partner or dating violence and symptoms of depression, diagnosed major depressive disorder, dysthymia, mild depression, or suicide attempts. Random effects meta-analyses were used to generate pooled odds ratios (ORs). Sixteen studies with 36,163 participants met our inclusion criteria. All studies included female participants; four studies also included male participants. Few controlled for key potential confounders other than demographics. All but one depression study measured only depressive symptoms. For women, there was clear evidence of an association between IPV and incident depressive symptoms, with 12 of 13 studies showing a positive direction of association and 11 reaching statistical significance; pooled OR from six studies = 1.97 (95% CI 1.56-2.48, I²  =  50.4%, p(heterogeneity = 0.073). There was also evidence of an association in the reverse direction between depressive symptoms and incident IPV (pooled OR from four studies = 1.93, 95% CI 1.51-2.48, I²  =  0%, p = 0.481). IPV was also associated with incident suicide attempts. For men, evidence suggested that IPV was associated with incident depressive symptoms, but there was no clear evidence of an association between IPV and suicide attempts or depression and incident IPV. In women, IPV was associated with incident depressive symptoms, and depressive symptoms with incident IPV. IPV was associated with incident suicide attempts. In men, few studies were conducted, but evidence suggested IPV was associated with incident depressive symptoms. There was no clear evidence of association with suicide attempts.

Impact of Adverse Childhood Experiences on Intimate Partner Violence Perpetration among Sri Lankan Men

In Sri Lanka, over one in three women experience intimate partner violence (IPV) victimization in their lifetime, making it a serious public health concern. Adverse childhood experiences (ACEs) such as child abuse and neglect, witnessing domestic violence, parental separation, and bullying are also widespread. Studies in Western settings have shown positive associations between ACEs and IPV perpetration in adulthood, but few have examined this relationship in a non-Western context. In the present study, we examined the association of ACEs with IPV perpetration among Sri Lankan men surveyed for the UN Multi-Country Study on Men and Violence in Asia and the Pacific. We found statistically significant positive associations between the number of ACE categories (ACE score) and emotional, financial, physical, and sexual IPV perpetration among Sri Lankan men. We analyzed the contributions of each ACE category and found that childhood abuse was strongly associated with perpetration of IPV in adulthood, with sexual abuse associated with the greatest increase in odds of perpetration (Adjusted odds ratio 2.36; 95% confidence interval: 1.69, 3.30). Witnessing abuse of one’s mother was associated with the greatest increase in the odds of perpetrating physical IPV (AOR 1.82; 95% CI: 1.29, 2.58), while lack of a male parental figure was not associated with physical IPV perpetration (AOR 0.76; 95% CI: 0.53, 1.09). These findings support a social learning theory of IPV perpetration, in which children who are exposed to violence learn to perpetrate IPV in adulthood. They also suggest that in Sri Lanka, being raised in a female-headed household does not increase the risk of IPV perpetration in adulthood compared to being raised in a household with a male parental figure. The relationship between being raised in a female-headed household (the number of which increased dramatically during Sri Lanka’s recent civil war) and perpetration of IPV warrants further study. Interventions that aim to decrease childhood abuse in Sri Lanka could both protect children now and reduce IPV in the future, decreasing violence on multiple fronts. PMID:26295577

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

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.

Objectives 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. Design 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. Setting and participants 33 542 women giving birth in a major health facility in Western Sydney. Primary outcomes Incidence of IPV, association with IPV and other psychosocial variables and maternal and perinatal outcomes. Result 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.

Background Intimate partner violence (IPV) and termination of pregnancy (TOP) are global health concerns, but their interaction is undetermined. The aim of this study was to determine whether there is an association between IPV and TOP. Methods and Findings A systematic review based on a search of Medline, Embase, PsycINFO, and Ovid Maternity and Infant Care from each database's inception to 21 September 2013 for peer-reviewed articles of any design and language found 74 studies regarding women who had undergone TOP and had experienced at least one domain (physical, sexual, or emotional) of IPV. Prevalence of IPV and association between IPV and TOP were meta-analysed. Sample sizes ranged from eight to 33,385 participants. Worldwide, rates of IPV in the preceding year in women undergoing TOP ranged from 2.5% to 30%. Lifetime prevalence by meta-analysis was shown to be 24.9% (95% CI 19.9% to 30.6%); heterogeneity was high (I 2>90%), and variation was not explained by study design, quality, or size, or country gross national income per capita. IPV, including history of rape, sexual assault, contraceptive sabotage, and coerced decision-making, was associated with TOP, and with repeat TOPs. By meta-analysis, partner not knowing about the TOP was shown to be significantly associated with IPV (pooled odds ratio 2.97, 95% CI 2.39 to 3.69). Women in violent relationships were more likely to have concealed the TOP from their partner than those who were not. Demographic factors including age, ethnicity, education, marital status, income, employment, and drug and alcohol use showed no strong or consistent mediating effect. Few long-term outcomes were studied. Women welcomed the opportunity to disclose IPV and be offered help. Limitations include study heterogeneity, potential underreporting of both IPV and TOP in primary data sources, and inherent difficulties in validation. Conclusions IPV is associated with TOP. Novel public health approaches are required to prevent IPV. TOP services provide an opportune health-based setting to design and test interventions.

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

PubMed

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.

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.

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.

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), substance use, and HIV are often co-occuring health problems affecting low-income urban women, and have been described as connected epidemics making up a "syndemic." Research suggests that each issue separately is associated with depressive symptoms, but no studies have examined the combined effect of IPV, substance use and HIV on women's depression. Interviews were conducted with 96 women recruited from community health clinics serving low-income women in an urban U.S. city. All women were over 17, not pregnant, English-speaking, without private insurance and had experienced physical IPV in the past year. Women were primarily African American (82%) and 82% were receiving income assistance. Twenty seven percent were HIV-positive, and 27% had used heroin or cocaine in the past 6 months. Based on the Centers for Epidemiological Studies Depression Scale (CES-D ), 73% were depressed. Women who experienced severe IPV in the past 6 months were compared to women who experienced no IPV or psychological IPV only in the past 6 months; those who experienced severe IPV were 5.3 times more likely to be depressed, controlling for HIV status, drug use, age, and relationship status. Women who experienced severe IPV, were HIV-positive, and used drugs (7.3% of sample) were 7.98 times as likely to be depressed as women without these characteristics. These findings confirm that severe IPV is significantly associated with depression among urban abused women. Furthermore, this research suggests that the syndemic effect of IPV, substance use, and HIV could be even more detrimental to women's mental health. Health practitioners and researchers should be aware of the combined impact of the IPV, substance use, and HIV syndemic and consider how they can address the mental health needs of urban women.

Rotavirus is the leading cause of severe acute gastroenteritis in infants and young children. Most children are infected with rotavirus, and the health and economic burdens of rotavirus gastroenteritis on healthcare systems and families are considerable. In 2012 pentavalent rotavirus vaccine (RV5) and diphtheria, tetanus, acellular pertussis and inactivated poliovirus vaccine derived from Sabin strains (DTaP-sIPV) were licensed in Japan. We examined the immunogenicity and safety of DTaP-sIPV when administrated concomitantly with RV5 in Japanese infants. A total of 192 infants 6 to 11 weeks of age randomized to Group 1 (N = 96) received DTaP-sIPV and RV5 concomitantly, and Group 2 (N = 96) received DTaP-sIPV and RV5 separately. Antibody titer to diphtheria toxin, pertussis antigens (PT and FHA), tetanus toxin, and poliovirus type 1, 2, and 3 were measured at 4 to 6 weeks following 3-doses of DTaP-sIPV. Seroprotection rates for all components of DTaP-sIPV were 100% in both groups, and the geometric mean titers for DTaP-sIPV in Group 1 were comparable to Group 2. Incidence of systemic AEs (including diarrhea, vomiting, fever, and nasopharyngitis) were lower in Group 1 than in Group 2. All vaccine-related AEs were mild or moderate in intensity. There were no vaccine-related serious AEs, no deaths, and no cases of intussusception during the study. Concomitant administration of DTaP-sIPV and RV5 induced satisfactory immune responses to DTaP-sIPV and acceptable safety profile. The administration of DTaP-sIPV given concomitantly with RV5 is expected to facilitate compliance with the vaccination schedule and improve vaccine coverage in Japanese infants.

Approximately 80% of new HIV infections among U.S. women are among black/African American and Hispanic women. HIV risk may be associated with intimate partner violence (IPV); data regarding IPV for women in high-HIV prevalence areas are scarce. To examine prevalence and correlates of IPV among women. Heterosexual women and their male partners in cities with high HIV prevalence were enrolled. During 2006-2007, participants completed interviews about HIV risk factors and IPV (physical violence or forced sex) experiences. Data were analyzed during 2012-2013 using multivariate logistic regression to identify individual- and partner-level IPV correlates. Of 1,011 female respondents, 985 (97.4%) provided risk factor and demographic data. Most were non-Hispanic black/African American (82.7%); living at or below poverty (86.7%); and tested HIV-negative (96.8%). IPV-physical violence was reported by 29.1%, and IPV-forced sex by 13.7%. Being married/living with a partner (AOR=1.60, 95% CI=1.06, 2.40); non-injection drug use (AOR=1.74, 95% CI=1.22, 2.48); and ever discussing male partners' number of current sex partners (AOR=1.60, 95% CI=1.15, 2.24) were associated with IPV-physical violence. Women reporting concurrent sex partners (AOR=1.80, 95% CI=1.04, 3.13) and ever discussing number of male partners' past sex partners (AOR=1.85, 95% CI=1.13, 3.05) were associated with IPV-forced sex. Feeling comfortable asking a male partner to use condoms was associated with decreased IPV-physical violence (AOR=0.32, 95% CI=0.16,0.64) and -forced sex (AOR=0.37, 95% CI=0.16, 0.85). Prevention interventions that enhance women's skills to decrease HIV and IPV risk are important strategies for decreasing racial/ethnic disparities among women. Published by Elsevier Inc.

Combination vaccines represent one solution to the problem of increased numbers of injections during single clinic visits. A combined DTaP-IPV (Infanrix-IPV) vaccine has been developed for use as a pre-school booster. Four hundred healthy children aged 4-6 years previously primed with 4 doses of DTaP vaccine (Infanrix), 3 doses of poliovirus vaccine and 1 dose of MMR vaccine were randomized to receive single doses of either the combined DTaP-IPV vaccine or separate DTaP and IPV vaccines in a Phase II trial (DTaP-IPV-047). All children also received a second dose of MMR vaccine. Immunogenicity was assessed in serum samples taken before and 1 month after booster administration. Safety was actively assessed for 42 days post-vaccination. Non-inferiority of the DTaP-IPV vaccine to separate DTaP and IPV vaccines was demonstrated for all DTaP antigen booster response rates and poliovirus geometric mean titers of antibody ratios. Post-vaccination, > or =99.4% of children in both groups had seroprotective levels of anti-diphtheria and anti-tetanus antibodies (> or =0.1IU/mL) and seroprotective anti-poliovirus antibody titers (> or =1:8). All children in both groups were seropositive for measles, mumps and rubella antibodies, with similar post-vaccination geometric mean concentrations/titers. No significant differences were observed in the incidence of solicited local or general symptoms, unsolicited symptoms and serious adverse events between the two groups. This combined DTaP-IPV appeared safe and immunogenic when given as a booster dose at 4-6 years of age. The DTaP-IPV vaccine had no negative effect on the response to co-administered MMR vaccine, making it well-suited for use as a pre-school booster.

Intimate partner violence (IPV) and HIV are important and interconnected public health concerns. While it is recognized that they share common social drivers, there is limited evidence surrounding the potential of community interventions to reduce violence and HIV risk at the community level. The SASA! study assessed the community-level impact of SASA!, a community mobilization intervention to prevent violence and reduce HIV-risk behaviors. From 2007 to 2012 a pair-matched cluster randomized controlled trial (CRT) was conducted in eight communities (four intervention and four control) in Kampala, Uganda. Cross-sectional surveys of a random sample of community members, 18- to 49-years old, were undertaken at baseline (n = 1,583) and four years post intervention implementation (n = 2,532). Six violence and HIV-related primary outcomes were defined a priori. An adjusted cluster-level intention-to-treat analysis compared outcomes in intervention and control communities at follow-up. The intervention was associated with significantly lower social acceptance of IPV among women (adjusted risk ratio 0.54, 95% confidence interval (CI) 0.38 to 0.79) and lower acceptance among men (0.13, 95% CI 0.01 to 1.15); significantly greater acceptance that a woman can refuse sex among women (1.28, 95% CI 1.07 to 1.52) and men (1.31, 95% CI 1.00 to 1.70); 52% lower past year experience of physical IPV among women (0.48, 95% CI 0.16 to 1.39); and lower levels of past year experience of sexual IPV (0.76, 95% CI 0.33 to 1.72). Women experiencing violence in intervention communities were more likely to receive supportive community responses. Reported past year sexual concurrency by men was significantly lower in intervention compared to control communities (0.57, 95% CI 0.36 to 0.91). This is the first CRT in sub-Saharan Africa to assess the community impact of a mobilization program on the social acceptability of IPV, the past year prevalence of IPV and levels of sexual concurrency. SASA! achieved important community impacts, and is now being delivered in control communities and replicated in 15 countries. ClinicalTrials.gov #NCT00790959.

Background Intimate partner violence (IPV) research has primarily focused on heterosexual couples, but has largely ignored IPV among men who have sex with men (MSM). We examined IPV prevalence among MSM and men who have sex with men and women (MSMW) in China. Methods MSM over the age of 16 were recruited through three MSM-focused websites in China. An online survey containing items on sociodemographics, risk behaviors, IPV, and self-reported HIV or STI diagnosis was completed. Multivariate regression was used to examine associations between IPV and risk behaviors and an HIV or STI diagnosis. Results Among 610 participants, 182 (29.8%) reported experiencing at least one type of IPV. MSMW were at significantly greater risk for IPV (adjusted odds ratio (AOR) 1.65, 95% CI [1.08–2.53]) compared to MSM. Men who had experienced IPV were more likely to have participated in group sex (AOR 1.86, 95% CI [1.08–3.21]), to have had sex in exchange for gifts or money (AOR 5.06, 95% CI [2.47–10.35]), and to report a positive HIV diagnosis (AOR 2.59, 95% CI [1.22–5.51]). Conclusions There is a hidden epidemic of IPV among MSM in China, especially among MSMW. The hidden nature of MSM and MSMW suggests the need for a clinical environment more conducive to disclosure. Research is needed to understand the pathways linking IPV and HIV risk among MSM in order to optimize the design of effective interventions. PMID:26222752

Intimate partner violence (IPV) research has primarily focused on heterosexual couples but has largely ignored IPV among men who have sex with men (MSM). We examined IPV prevalence among MSM and men who have sex with men and women (MSMW) in China. Men who have sex with men older than 16 years were recruited through 3 MSM-focused Web sites in China. An online survey containing items on sociodemographics, risk behaviors, IPV, and self-reported HIV or sexually transmitted infection diagnosis was completed. Multivariate regression was used to examine associations between IPV and risk behaviors and an HIV or sexually transmitted infection diagnosis. Among 610 participants, 182 (29.8%) reported experiencing at least 1 type of IPV. Men who have sex with both men and women were at significantly greater risk for IPV (adjusted odds ratio [AOR], 1.65; 95% confidence interval [CI], 1.08-2.53) compared with MSM. Men who had experienced IPV were more likely to have participated in group sex (AOR, 1.86; 95% CI, 1.08-3.21), to have had sex in exchange for gifts or money (AOR, 5.06; 95% CI, 2.47-10.35), and to report a positive HIV diagnosis (AOR, 2.59; 95% CI, 1.22-5.51). There is a hidden epidemic of IPV among MSM in China, especially among MSMW. The hidden nature of MSM and MSMW suggests the need for a clinical environment more conducive to disclosure.

Objective Evidence has linked economic hardship with increased intimate partner violence (IPV) perpetration among males. However, less is known about how economic debt or gender norms related to men's roles in relationships or the household, which often underlie IPV perpetration, intersect in or may explain these associations. We assessed the intersection of economic debt, attitudes toward gender norms, and IPV perpetration among married men in India. Methods Data were from the evaluation of a family planning intervention among young married couples (n=1,081) in rural Maharashtra, India. Crude and adjusted logistic regression models for dichotomous outcome variables and linear regression models for continuous outcomes were used to examine debt in relation to husbands' attitudes toward gender-based norms (i.e., beliefs supporting IPV and beliefs regarding male dominance in relationships and the household), as well as sexual and physical IPV perpetration. Results Twenty percent of husbands reported debt. In adjusted linear regression models, debt was associated with husbands' attitudes supportive of IPV (b=0.015, p=0.004) and norms supporting male dominance in relationships and the household (b=0.006, p=0.003). In logistic regression models adjusted for relevant demographics, debt was associated with perpetration of physical IPV (adjusted odds ratio [AOR] = 1.4, 95% confidence interval [CI] 1.1, 1.9) and sexual IPV (AOR=1.6, 95% CI 1.1, 2.1) from husbands. These findings related to debt and relation to IPV were slightly attenuated when further adjusted for men's attitudes toward gender norms. Conclusion Findings suggest the need for combined gender equity and economic promotion interventions to address high levels of debt and related IPV reported among married couples in rural India.

Young children living with intimate partner violence (IPV) are often also exposed to harsh parenting. Both forms of violence increase children’s risk for clinically significant disruptive behavior, which can place them on a developmental trajectory associated with serious psychological impairment later in life. Although it is hypothesized that IPV behaviors may spillover into harsh parenting, and thereby influence risk for disruptive behavior, relatively little is known about these processes in families with young children. The current study examines the overlap of the quality and frequency of psychological and physical forms of IPV and harsh parenting, and tests whether harsh parenting mediates the relationship between IPV and child disruptive behavior in a diverse cross-sectional sample of 81 children ages 4 to 6 years. Results suggest that mothers reporting a greater occurrence of psychologically aggressive IPV (e.g., yelling, name-calling) more often engage in psychological and physical aggression toward their children (odds ratios [ORs] = 4.6–9.9). Mothers reporting a greater occurrence of IPV in the form of physical assault more often engage in mild to more severe forms of physical punishment with potential harm to the child (ORs = 3.8–5.0). Psychological and physical forms of IPV and harsh parenting all significantly correlated with maternal reports of child disruptive behavior (r = .29–.40). Psychological harsh parenting partially mediated the association between psychological IPV and child disruptive behavior. However, a significant direct effect of psychological IPV on preschool children’s disruptive behavior remained. Implications for child welfare policy and practice and intervention, including the need for increased awareness of the negative impact of psychological IPV on young children, are discussed.

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.

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

Evidence has linked economic hardship with increased intimate partner violence (IPV) perpetration among males. However, less is known about how economic debt or gender norms related to men's roles in relationships or the household, which often underlie IPV perpetration, intersect in or may explain these associations. We assessed the intersection of economic debt, attitudes toward gender norms, and IPV perpetration among married men in India. Data were from the evaluation of a family planning intervention among young married couples (n=1,081) in rural Maharashtra, India. Crude and adjusted logistic regression models for dichotomous outcome variables and linear regression models for continuous outcomes were used to examine debt in relation to husbands' attitudes toward gender-based norms (i.e., beliefs supporting IPV and beliefs regarding male dominance in relationships and the household), as well as sexual and physical IPV perpetration. Twenty percent of husbands reported debt. In adjusted linear regression models, debt was associated with husbands' attitudes supportive of IPV (b=0.015, p=0.004) and norms supporting male dominance in relationships and the household (b=0.006, p=0.003). In logistic regression models adjusted for relevant demographics, debt was associated with perpetration of physical IPV (adjusted odds ratio [AOR] = 1.4, 95% confidence interval [CI] 1.1, 1.9) and sexual IPV (AOR=1.6, 95% CI 1.1, 2.1) from husbands. These findings related to debt and relation to IPV were slightly attenuated when further adjusted for men's attitudes toward gender norms. Findings suggest the need for combined gender equity and economic promotion interventions to address high levels of debt and related IPV reported among married couples in rural India.

Objective This study examined whether socioeconomic status moderated the association between intimate partner violence (IPV) and postpartum depression among a community-based sample of women. Defining the role of poverty in the risk of postpartum depression for IPV victims enables prioritization of health promotion efforts to maximize the effectiveness of existing maternal-infant resources. Methods This cross-sectional telephone-survey study interviewed 301 postpartum women 2 months after delivery, screening them for IPV and depression [using Edinburgh Postnatal Depression Scale (EPDS)]. Socioeconomic status was defined by insurance (Medicaid-paid-delivery or not). This analysis controlled for the following covariates, collected through interview and medical-record review: demographics, obstetric history, prenatal health and additional psychosocial risk factors. After adjusting for significant covariates, multiple linear regression was conducted to test whether socioeconomic status confounded or moderated IPV's relationship with EPDS-score. Results Ten percent of participants screened positive for postpartum depression, 21.3 % screened positive for current or previous adult emotional or physical abuse by a partner, and 32.2 % met poverty criteria. IPV and poverty were positively associated with each other (χ(2) (1) = 11.76, p < .001) and with EPDS score (IPV: beta 3.2 (CI 2.0, 4.5) p < .001, poverty: beta 1.3 (CI 0.2, 2.4) p = .017). In the multiple linear regression, IPV remained significantly associated, but poverty did not (IPV: adjusted beta 3.1 (CI 1.8, 4.3) p < .001, poverty: adjusted beta 0.8 (CI -0.3, 1.9) p = .141), and no statistically significant interaction between IPV and poverty was found. Conclusions Study findings illustrated that IPV was strongly associated with postpartum depression, outweighing the influence of socioeconomic status upon depression for postpartum women.

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.

Gender inequities place women at an increased risk for HIV acquisition, and this association may particularly disenfranchize young pregnant women. Intimate partner violence (IPV) and food insecurity may contribute to gender differences in power, thereby influencing HIV disparities between women and men. Factors influencing gender disparities in HIV are unique and country-specific within sub-Saharan Africa, yet these factors are understudied among women in Liberia. This paper sought to examine the unique contributions and intersections of intimate partner violence (IPV) and food insecurity with HIV-related risk factors among young pregnant women in Liberia. Between March 2016 and August 2016, cross-sectional data collected from 195 women aged 18-30, residing in Monrovia, Liberia who were receiving prenatal services were used to examine the independent and interaction effects of IPV and food insecurity on HIV-related risk factors (i.e., sexual partner concurrency, economically-motivated relationships). IPV (31.3%) and food insecurity (47.7%) were prevalent. Young women who experience IPV are more likely to report food insecurity (p < 0.05). Young women who experienced IPV and food insecurity were more likely to start a new relationship for economic support (ps < 0.05). Young women who experience IPV and food insecurity were more likely to report engaging in transactional sex (ps < 0.05). There were no significant interaction effects between IPV and food insecurity (ps > 0.05). IPV and food insecurity each uniquely heighten young Liberian women's vulnerability to HIV. Intervention and policy efforts are need to promote and empower women's sexual health through integrated sexual and reproductive health services, and reduce IPV and food insecurity among pregnant Liberian women.

The sleeper effect of intimate partner violence exposure: long-term consequences on young children's aggressive behavior.

Holmes, Megan R

2013-09-01

Children who have been exposed to intimate partner violence (IPV) experience a wide variety of short-term social adjustment and emotional difficulties, including externalizing behavioral problems such as aggression. While children are affected by IPV at all ages, little is known about the long-term consequences of IPV exposure at younger ages. Because early experiences provide the foundation for later development, children exposed to IPV as an infant or toddler may experience worse negative outcomes over time than children never exposed. Using the National Survey of Child and Adolescent Well-Being (NSCAW), latent growth curve modeling was conducted to examine whether early IPV exposure occurring between birth and age three (n = 107), compared with no exposure (n = 339), affects the development of aggressive behavior over 5 years. This modeling allowed for empirical exploration of developmental trajectories, and considered whether initial social development trajectories and change over time vary according to early IPV exposure. Children who were exposed to more frequent early IPV did not have significantly different aggressive behavior problems initially than children who were never exposed. However, over time, the more frequently children were exposed between birth and 3 years, the more aggressive behavior problems were exhibited by age eight. Results indicate a long-term negative behavioral effect on children who have been exposed to IPV at an early age. An initial assessment directly following exposure to IPV may not be able to identify behavior problems in young children. Because the negative effects of early IPV exposure are delayed until the child is of school age, early intervention is necessary for reducing the risk of later aggressive behavior. © 2013 The Authors.

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.

Young children living with intimate partner violence (IPV) are often also exposed to harsh parenting. Both forms of violence increase children's risk for clinically significant disruptive behavior, which can place them on a developmental trajectory associated with serious psychological impairment later in life. Although it is hypothesized that IPV behaviors may spillover into harsh parenting, and thereby influence risk for disruptive behavior, relatively little is known about these processes in families with young children. The current study examines the overlap of the quality and frequency of psychological and physical forms of IPV and harsh parenting, and tests whether harsh parenting mediates the relationship between IPV and child disruptive behavior in a diverse cross-sectional sample of 81 children ages 4 to 6 years. Results suggest that mothers reporting a greater occurrence of psychologically aggressive IPV (e.g., yelling, name-calling) more often engage in psychological and physical aggression toward their children (odds ratios [ORs] = 4.6-9.9). Mothers reporting a greater occurrence of IPV in the form of physical assault more often engage in mild to more severe forms of physical punishment with potential harm to the child (ORs = 3.8-5.0). Psychological and physical forms of IPV and harsh parenting all significantly correlated with maternal reports of child disruptive behavior (r = .29-.40). Psychological harsh parenting partially mediated the association between psychological IPV and child disruptive behavior. However, a significant direct effect of psychological IPV on preschool children's disruptive behavior remained. Implications for child welfare policy and practice and intervention, including the need for increased awareness of the negative impact of psychological IPV on young children, are discussed. © The Author(s) 2015.

This study explores the association between adolescent marriage and intimate partner violence (IPV) among young adult women using 2007 Bangladesh Demographic Health Survey data. The analyses are restricted to young women 20 to 24 years old. Logistic regression analyses are constructed to estimate the odds ratios and 95% confidence intervals for the association between adolescent marriage and IPV in the past year. show that there is a strong significant relationship between adolescent marriage and experience of physical IPV in the past year among this population. Association between sexual IPV and adolescent marriage is insignificant. Adolescent marriage puts women at increased risk of physical IPV into their young adult period. Government agencies need to enforce existing law on the minimum age at marriage to reduce IPV among adolescent and young adult girls.

This article investigates the overlap between offending trajectories, criminal violence, and intimate partner violence (IPV) and the factors associated with these behaviors. Knowledge on these questions is relevant to theory and policy. For the former, this article considers the extent to which specific theories are needed for understanding crime, criminal violence, and/or IPV, whereas for the latter, it may suggest specific offense- and offender-based policies. We use data from the Cambridge Study in Delinquent Development that traces the offending, criminal violence, and IPV of males to age 50. Findings show that there is significant overlap between criminal violence and IPV, high-rate offending trajectories have increased odds of criminal violence and IPV, and early childhood risk factors have no additional effect on criminal violence and IPV in adulthood over and above the offending trajectories.

Pulmonary emphysema causes several electrocardiogram changes, and one of the most common and well known is on the frontal P-wave axis. P-axis verticalization (P-axis > 60°) serves as a quasidiagnostic indicator of emphysema. The correlation of P-axis verticalization with the radiological severity of emphysema and severity of chronic obstructive lung function have been previously investigated and well described in the literature. However, the correlation of P-axis verticalization in emphysema with other P-indices like P-terminal force in V1 (Ptf), amplitude of initial positive component of P-waves in V1 (i-PV1), and interatrial block (IAB) have not been well studied. Our current study was undertaken to investigate the effects of emphysema on these P-wave indices in correlation with the verticalization of the P-vector. Unselected, routinely recorded electrocardiograms of 170 hospitalized emphysema patients were studied. Significant Ptf (s-Ptf) was considered ≥40 mm.ms and was divided into two types based on the morphology of P-waves in V1: either a totally negative (-) P wave in V1 or a biphasic (+/-) P wave in V1. s-Ptf correlated better with vertical P-vectors than nonvertical P-vectors (P = 0.03). s-Ptf also significantly correlated with IAB (P = 0.001); however, IAB and P-vector verticalization did not appear to have any significant correlation (P = 0.23). There was a very weak correlation between i-PV1 and frontal P-vector (r = 0.15; P = 0.047); however, no significant correlation was found between i-PV1 and P-amplitude in lead III (r = 0.07; P = 0.36). We conclude that increased P-tf in emphysema may be due to downward right atrial position caused by right atrial displacement, and thus the common assumption that increased P-tf implies left atrial enlargement should be made with caution in patients with emphysema. Also, the lack of strong correlation between i-PV1 and P-amplitude in lead III or vertical P-vector may suggest the predominant role of downward right atrial distortion rather than right atrial enlargement in causing vertical P-vector in emphysema.

Keeping it in the family: intergenerational transmission of violence in Cebu, Philippines.

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.

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.

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.

Women's greatest risk of violence in the Democratic Republic of Congo (DRC) may come from an intimate partner, but few studies have analyzed context-specific risk and protective factors for intimate partner violence (IPV) in the DRC. This study analyzed data from the most recent Demographic and Health Survey (DHS) in Congo to assess risk and protective factors for IPV and the role of women's status, a factor implicated in prior IPV research. Using a sample of 1,821 married or cohabiting women between the ages of 15 and 49, four logistic regression models tested relationships between physical, sexual, emotional, or any violence and independent variables of interest. Results indicated that 68.2% of respondents had experienced at least one of the three types of IPV. An attitude of acceptance toward spousal violence was associated with increased risk for physical and emotional IPV. Women who were the only wife of their husband were half as likely to experience IPV compared with women whose husbands had other wives or women who did not know their husbands' marital status. Partner's use of alcohol was associated with nearly doubled risk for both physical and sexual IPV. The study's results indicate that IPV occurs frequently and is justified as acceptable by many women in the DRC. Findings suggest that awareness-raising campaigns may be a helpful intervention and that partner characteristics should be considered when assessing women's risk for IPV. © The Author(s) 2014.

Male perpetration of intimate partner violence (IPV) against women in sub-Saharan Africa is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, though research on this topic in the region is limited. We assessed the degree to which peer network gender norms are associated with Tanzanian men's perpetration of IPV and examined whether the social cohesion of peer networks moderates this relationship. Using baseline data from sexually active men (n = 1103) nested within 59 peer networks enrolled in an on-going cluster-randomized HIV and IPV prevention trial, we fit multilevel logistic regression models to examine peer network-level factors associated with past-year physical IPV perpetration. Peer network gender norms were significantly associated with men's risk of perpetrating IPV, even after adjusting for their own attitudes toward gender roles (OR = 1.53 , p =  . 04). Peer network social cohesion moderated this relationship (OR = 1.50 , p =  . 04); the positive relationship between increasingly inequitable (i.e., traditional) peer network gender norms and men's risk of perpetrating IPV became stronger, as peer network social cohesion increased. Characteristics of the peer network context are associated with men's IPV perpetration and should be targeted in future interventions. While many IPV prevention interventions focus on changing individual attitudes, our findings support a unique approach, focused on transforming the peer context.

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.

We conducted a follow-on study to a phase I randomized, controlled trial conducted in Cuba, 2012, to assess the persistence of poliovirus antibodies at 21-22 months following booster dose of Sabin-IPV compared to Salk-IPV in adults who had received multiple doses of oral poliovirus vaccine (OPV) during childhood. In 2012, 60 healthy adult males aged 19-23 were randomized to receive one booster dose, of either Sabin-inactivated poliovirus vaccine (Sabin-IPV), adjuvanted Sabin-IPV (aSabin-IPV), or conventional Salk-IPV. In the original study, blood was collected at days 0 (before) and 28 (after vaccination), respectively. In this study, an additional blood sample was collected 21-22 months after vaccination, and tested for neutralizing antibodies to Sabin poliovirus types 1, 2 and 3. We collected sera from 59/60 (98.3%) subjects; 59/59 (100%) remained seropositive to all poliovirus types, 21-22 months after vaccination. The decay curves were very similar among the study groups. Between day 28 and 21-22 months, there was a reduction of ⩾87.4% in median antibody levels for all poliovirus types in all study groups, with no significant differences between the study groups. The decay of poliovirus antibodies over a 21-22-month period was similar regardless of the type of booster vaccine used, suggesting the scientific data of Salk IPV long-term persistence and decay may be broadly applicable to Sabin IPV.

Intimate partner violence (IPV) is a major public health problem with significant impact on the workplace. Employee assistance programs (EAPs) are a confidential benefit to assist employees and their families with a variety of problems that may negatively affect their job performance. The purpose of this systematic review is to study the extant literature to identify articles that have explored the role of EAPs in addressing IPV. We searched Medline, PsychINFO, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) for English-language papers that have explored how EAPs can address IPV. Articles published through 2008 were included. Our review yielded nine articles, mostly from EAP-centered journals. Nearly all of the studies were published before the year 2000 and primarily describe the need for EAPs to be more engaged in preventing violence against women. Most of the studies were commentaries, often using case reports to support recommendations on how EAPs could address IPV. Results from the two intervention studies revealed close connections between EAP clients being treated for alcoholism and IPV perpetration and the effectiveness of a standardized tool to identify EAP clients experiencing IPV. Research in this area is in its infancy, and more studies are needed to inform the formulation of evidence-based policies and programs that guide the role of EAPs in addressing IPV. The lack of research on how EAPs address IPV is alarming, as many employers state that they often refer employees affected by IPV to the EAP for assistance.

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.

To describe the design, methods, procedures and characteristics of the population involved in a study designed to compare Intimate Partner Violence (IPV) in eight European countries. Women and men aged 18-65, living in Ghent-Belgium (n = 245), Stuttgart-Germany (n = 546), Athens-Greece (n = 548), Budapest-Hungary (n = 604), Porto-Portugal (n = 635), Granada-Spain (n = 138), Östersund-Sweden (n = 592), London-United Kingdom (n = 571), were sampled and administered a common questionnaire. Chi-square goodness of fit and five-age strata population fractions ratios for sex and education were computed to evaluate samples' representativeness. Differences in the age distributions were found among women from Sweden and Portugal and among men from Belgium, Hungary, Portugal and Sweden. Over-recruitment of more educated respondents was noted in all sites. The use of a common research protocol with the same structured questionnaire is likely to provide accurate estimates of the general population IPV frequency, despite limitations in probabilistic sampling and restrictions in methods of administration.

Intimate partner violence: IPV in the LGBT community.

PubMed

Chen, Ping-Hsin; Jacobs, Abbie; Rovi, Susan L D

2013-09-01

Nationally, the rates of intimate partner violence (IPV) among lesbian, gay, bisexual, or transgender (LGBT) individuals are similar to or greater than rates for heterosexuals. Many have experienced psychological and physical abuse as sexual minorities, making it difficult for them to seek help for IPV. Physician behavior, such as not assuming that all patients are heterosexual, being nonjudgmental, and using inclusive language, can empower LGBT patients to disclose IPV. Also, physicians should ascertain the degree to which the patient is out. The threat of being outed can be an aspect of the power and control exerted by an abusive partner and a significant barrier to seeking help. Physicians should screen for IPV and intervene in a similar manner with LGBT and non-LGBT patients, but they should be aware of potential limitations in resources for LGBT patients, such as shelters. As sexual minorities experiencing IPV, LGBT individuals are at greater risk of depression and substance abuse than are non-LGBT individuals. Minority stress, resulting from stigmatization and discrimination, can be exacerbated by IPV. Physicians should learn about legal issues for LGBT individuals and the availability of community or advocacy programs for LGBT perpetrators or victims of IPV.

Dixon, Kristiana J; Edwards, Katie M; Gidycz, Christine A

2016-10-01

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.

Neighborhoods and Intimate Partner Violence Against Women: The Direct and Interactive Effects of Social Ties and Collective Efficacy.

Wright, Emily M; Skubak Tillyer, Marie

2017-06-01

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."

Family identification: a beneficial process for young adults who grow up in homes affected by parental intimate partner violence

Exposure to parental intimate partner violence (parental IPV) is a complex trauma. Research within social psychology establishes that identification with social groups impacts positively on how we appraise, respond to and recover from traumatic events. IPV is also a highly stigmatized social phenomenon and social isolation is a major factor for families affected by IPV, yet strong identification with the family group may act as a beneficial psychological resource to young people who grew up in homes affected by IPV. The current study, an online survey of 355 students (Mage = 20, 70% female), investigated if a psychosocial process, specifically identification with the family, may influence the relationship between the predictor, exposure to parental IPV, and outcomes, global self-esteem and state anxiety. Mediation analysis suggests that identification with the family has a positive influence on the relationship between exposure to parental IPV and psychological outcomes; exposure to parental IPV results in reduced family identification, but when family identification is strong it results in both reduced anxiety and increased self-esteem for young people. The findings highlight the importance of having a strong sense of belonging to the extended family for young people who were exposed to parental IPV, thus has implications for prevention, intervention, and social policy.

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: office screening for victims and perpetrators of IPV.

Chen, Ping-Hsin; Jacobs, Abbie; Rovi, Susan L D

2013-09-01

Intimate partner violence (IPV) affects more than 12 million individuals annually. Power and control are central concepts underlying abusive relationships. Physicians may see IPV victims, perpetrators, and their children for annual examinations, as well as for injuries and health conditions associated with abuse. In 2013, the US Preventive Services Task Force recommended that women of childbearing age (ie, 14 to 46 years) be screened for IPV. Brief, validated screening tools, such as the 4-item Hurt, Insult, Threaten, and Scream (HITS), can be used to facilitate screening. Physicians should always assess patients whose medical histories or presenting symptoms or injuries are consistent with abuse. Risk factors for IPV and consequences of abuse include general health conditions (eg, asthma, irritable bowel syndrome), reproductive issues (eg, gynecologic disorders, unintended pregnancies), psychological conditions (eg, depression, sleep disturbances), and risky health behaviors (eg, substance use, poor health care adherence). Tools for identifying perpetrators are under investigation. To prepare the practice to address IPV, physicians should educate themselves and staff and learn about community and national resources. By identifying and responding to IPV, clinicians may be able to reduce IPV and interrupt the intergenerational cycle of violence.

Assess the link between levels of armed conflict and postconflict intimate partner violence (IPV) experienced by women in Liberia. Armed Conflict Location and Event Data Project data were used to measure conflict-related fatalities in districts in Liberia during the country's civil war from 1999 to 2003. These data were linked to individual-level data from the 2007 Demographic and Health Survey, including past-year IPV. Multilevel logistic models accounting for the clustering of women within districts evaluated the relationship of conflict fatalities with postconflict past-year IPV. Additional conflict measures, including conflict events and cumulative years of conflict, were assessed. After adjusting for individual-level characteristics correlated with IPV, residence in a conflict fatality-affected district was associated with a 50% increase in risk of IPV (adjusted OR (aOR): 1.55, 95% CI 1.26 to 1.92). Women living in a district that experienced 4-5 cumulative years of conflict were also more likely to experience IPV (aOR 1.88, 95% CI 1.29 to 2.75). Residing in a conflict-affected district even 5 years after conflict was associated with postconflict IPV. Recognising and preventing postconflict IPV violence is important to support long-term recovery in postconflict settings.

Polio eradication is progressing rapidly, and the live attenuated Sabin strains in the oral poliovirus vaccine (OPV) are being removed sequentially, starting with type 2 in April 2016. For risk mitigation, countries are introducing inactivated poliovirus vaccine (IPV) into routine vaccination programs. After April 2016, monovalent type 2 OPV will be available for type 2 outbreak control. Because the current IPV is not suitable for house-to-house vaccination campaigns (the intramuscular injections require health professionals), we developed a high-density microprojection array, the Nanopatch, delivered monovalent type 2 IPV (IPV2) vaccine to the skin. To assess the immunogenicity of the Nanopatch, we performed a dose-matched study in rats, comparing the immunogenicity of IPV2 delivered by intramuscular injection or Nanopatch immunisation. A single dose of 0.2 D-antigen units of IPV2 elicited protective levels of poliovirus antibodies in 100% of animals. However, animals receiving IPV2 by IM required at least 3 immunisations to reach the same neutralising antibody titres. This level of dose reduction (1/40th of a full dose) is unprecedented for poliovirus vaccine delivery. The ease of administration coupled with the dose reduction observed in this study points to the Nanopatch as a potential tool for facilitating inexpensive IPV for mass vaccination campaigns.

Intimate partner violence among rural South African men: Alcohol use, sexual decision-making, and partner communication

Nearly one-third of South African men report enacting intimate partner violence (IPV). Beyond direct health consequences for women, IPV is also linked to varied risk behaviours among men who enact it, including alcohol abuse, risky sex, and poor health care uptake. Little is known about how to reduce IPV perpetration among men. We conducted retrospective, in-depth interviews with men (n=53) who participated in a rural South African program that targeted masculinities, HIV risk, and IPV. We conducted computer-assisted thematic qualitative coding alongside a simple rubric to understand how the program may lead to changes in IPV perpetration. Many men described new patterns of reduced alcohol intake and improved partner communication, allowing them to respond in ways that did not lead to the escalation of violence. Sexual decision-making changed via reduced sexual entitlement and increased mutuality about whether to have sex. Men articulated the intertwined nature of each of these topics, suggesting a syndemic lens may be useful for understanding IPV. These data suggest that alcohol and sexual relationship skills may be useful levers for future IPV programming, and that IPV may be a tractable issue as men learn new skills for enacting masculinities in their household and in intimate relationships.

"More Closeted Than Gayness Itself": The Depiction of Same-Sex Couple Violence in Newspaper Media.

Estes, Michelle L; Webber, Gretchen R

2017-10-01

Same-sex intimate partner violence (IPV) lacks mainstream news media coverage. News media report on those stories that are most prominent, and these stories are often shaped and presented within a White, heterosexual, upper-class, male framework. This framework largely ignores or misrepresents those that do not fit these characteristics, resulting in a gap in research and coverage of same-sex IPV. This article explores whether U.S. newspapers cover same-sex IPV, how often, and how same-sex couple violence is portrayed in newspapers when covered. Twenty-five newspaper articles published from 2005 to 2015, 10 years prior to the U.S. Supreme Court decision that legalized same-sex marriage, were located and analyzed. Findings indicate sparse newspaper coverage of IPV in same-sex couples. Ten articles highlight the lack of coverage and knowledge related to same-sex couple IPV. Eighteen articles address same-sex IPV as a social issue and highlight resource concerns, police involvement, and heteronormativity and heterosexism. Sixteen articles depict specific instances of IPV in same-sex couples. The overall lack of coverage and how same-sex IPV is covered remains problematic and limited. More mainstream and accurate coverage is needed to effectively address this social issue. Limitations and directions for future research are also discussed.

To identify the prevalence of intimate partner violence (IPV) against Japanese women (JW) and non-Japanese women (NJW) in a perinatal setting. Additional purposes were to identify the associated factors of IPV, describe the characteristics of IPV against NJW, and assess the acceptability of the Violence Against Women Screen (VAWS) instrument as a screening tool. A cross-sectional survey was conducted from September to November 2007 in an urban hospital maternity clinic in Tokyo, Japan. Women who attended the maternity clinic received the VAWS instrument, which was translated into four languages (Japanese with Kanji and Hiragana, English, Chinese, and Tagalog) and was used to identify IPV. A total of 400 women participated in the study: 357 were JW and 43 were NJW. The prevalence rate of IPV among the JW was 31.4% and 21.4% among the NJW. There was no statistical significance between the two groups. A multiple logistic regression with adjusted odds ratio identified two associated factors for IPV: being multipara and previous experience of physical violence from a partner. The prevalence of IPV was not statistically different among JW and NJW. Screening for IPV, early intervention, and support should be expanded in hospitals and maternity clinics in Japan.

Child welfare practitioners in many countries now have increased responsibility for assessing intimate partner violence (IPV) as part of their child risk assessment process. Much research-based knowledge has accumulated about IPV and its impact on children that can inform this process. This exploratory study examined the extent to which research-based knowledge in IPV is influencing what child welfare practitioners explore in relation to IPV during their assessment process. Using a focus group format, two cohorts of child welfare practitioners, one located in Dublin County, Ireland, and one from the New York City metropolitan area, were asked what information they deem critical to explore about IPV, why they explore this content, and how they explore it. Results indicated that a wide range of information about IPV was reported as gathered by both groups, however, explicit research knowledge was not identified as a major influence for exploring these areas. Standardized IPV risk assessment instruments were also not reported as used by any of the participants. Other influences, such as practice experience, social work education, and legal or regulatory directives, had a much greater influence on the social worker's information gathering process in relation to IPV than research.

We assessed programmatic adaptations and infants' uptake of inactivated poliovirus vaccine (IPV) after its introduction into the routine immunization schedule in Bangladesh. Using convenience and probability sampling, we selected 23 health facilities, 36 vaccinators, and 336 caregivers, within 5 districts and 3 city corporations. We collected data during August-October 2015 by conducting interviews, reviewing vaccination records, and observing activities. Knowledge about IPV was high among vaccinators (94%). No problems with IPV storage, transport, or waste disposal were detected, but shortages were reported in 20 health facilities (87%). Wastage per 5-dose vaccine vial was above the recommended 30% in 20 health facilities (87%); all were related to providing <5 doses per open vial. Among eligible infants, 87% and 86% received the third dose of pentavalent and oral poliovirus vaccine, respectively, but only 65% received IPV at the same visit. Among 73 infants not vaccinated with IPV, 58% of caregivers reported that vaccine was unavailable. Bangladesh successfully introduced IPV, but shortages related to insufficient global supply and high vaccine wastage in small outreach immunization sessions might reduce its impact on population immunity. Minimizing wastage and use of a 2-dose fractional-IPV schedule could extend IPV immunization to more children. © The Author 2017.

Intrahepatic portosystemic venous shunts (IPVS) are rare, except for the minute ones observed in cirrhotic liver. This report concerns a case with frequent episodes of consciousness loss, diagnosed as IPVS and multiple hemangioma-like lesions of the liver by US, CT and angiography. To our knowledge, this is the first report of association of IPVS and such angiographically evident hemangioma-like lesions of the liver. The etiology of IPVS is mostly considered to be congenital though, there are still many arguments about it. The relation between IPVS and the hemangioma-like lesions of the liver is discussed.

Best practices in advocating for economic empowerment of impoverished intimate partner violence (IPV) survivors require the comprehensive and holistic organization of program and service delivery systems. This article outlines the best practices literature that addresses IPV in the lives of impoverished women, as well as the literature that specifically examines the interventions to economically empower IPV survivors--whether impoverished or not. This article concludes with suggestions for policy makers on how to incorporate these best practices into the Violence Against Women Act and for practitioners to ensure a comprehensive approach to interventions for impoverished IPV survivors.

THE ATTENUATING EFFECT OF EMPOWERMENT ON IPV-RELATED PTSD SYMPTOMS IN BATTERED WOMEN LIVING IN DOMESTIC VIOLENCE SHELTERS

2010-01-01

Intimate partner violence (IPV) is associated with significant psychological distress, including posttraumatic stress disorder (PTSD). However, factors that attenuate the impact of IPV on PTSD remain largely unknown. Using hierarchical regression, this investigation explored the impact of resource acquisition and empowerment on the relationship between IPV and PTSD. Empowerment demonstrated greater relative importance over resource acquisition. Specifically, empowerment was found to attenuate the impact of IPV severity on PTSD at low and moderate levels of violence. The importance of fostering empowerment and addressing PTSD in addition to provision of resources in battered women is discussed. PMID:22411301

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.

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.

From "Buzzword" to Best Practice: Applying Intersectionality to Children Exposed to Intimate Partner Violence.

2016-03-07

Empirical studies on the impact of intimate partner violence (IPV) on children have burgeoned over the last three decades. Notably absent from existing approaches to studying children exposed to IPV, however, is attention to how various positionalities intersect to impact the experiences of children and their families. In fact, while the importance of an intersectional framework for understanding IPV has been discussed for over two decades, little or no attention has been given to issues of children's exposure to IPV. In this article, we examine the current state of the literature on children exposed to IPV through an exploratory meta-analysis, finding limited application of intersectionality and a focus on discrete categories of difference. We then demonstrate why and how an intersectional framework should be applied to children exposed to IPV, with specific strategies for research and policy. We suggest a child-centered approach that recognizes diversity among children exposed to IPV, extending the challenge to traditional "one-size-fits-all" models to include an intersectionality-informed stance. © The Author(s) 2016.

Intimate Partner Violence in Neighborhood Context: The Roles of Structural Disadvantage, Subjective Disorder, and Emotional Distress

Most theoretical treatments of intimate partner violence (IPV) focus on individual-level processes. Some researchers have attempted to situate IPV within the larger neighborhood context, but few studies have sought to link structural- and individual-level factors. The current analyses fill a research gap by examining the role of anger and depression in the association between neighborhood disadvantage and IPV. Using data from the Toledo Adolescent Relationships Study (TARS) and the 2000 Census, this study focuses on structural indicators of disadvantage as well as subjective disorder, and highlights the complex associations between neighborhood conditions, emotional distress, and IPV. Findings indicate that anger and depressive symptoms partially explain the association between neighborhood disadvantage and IPV. Additionally, the associations between disadvantage, disorder, and IPV depend on respondent’s level of anger. Results underscore the need to further consider the role of neighborhood factors (both objective and subjective) in relation to IPV, and also suggest the utility of introducing individual-level emotional measures to assess the circumstances under which neighborhoods matter most.

Prior reviews have identified elevated trait anger as a risk factor for intimate partner violence (IPV) perpetration. Given that 10 years have passed since the last comprehensive review of this literature, we provide an updated meta-analytic review examining associations among anger, hostility, internalizing negative emotions, and IPV for male and female perpetrators. One hundred and five effect sizes from 64 independent samples (61 studies) were included for analysis. IPV perpetration was moderately associated with the constructs of anger, hostility, and internalizing negative emotions. This association appeared stronger for those who perpetrated moderate to severe IPV compared to those who perpetrated low to moderate IPV, and did not vary across perpetrator sex, measurement method, relationship type, or perpetrator population. Implications and limitations of findings were reviewed in the context of theoretical models of IPV, and future directions for empirical and clinical endeavors were proposed. PMID:25752947

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.

Inactivated poliovirus vaccine and the final stages of poliovirus eradication.

Hovi, T

2001-03-21

The use of the inactivated poliovirus vaccine (IPV) will increase before and probably also after the global eradication of the wild type poliovirus. Before eradication, the switch from the use of oral poliovirus vaccine (OPV) to IPV has been due to the better safety record of IPV. Introduction of IPV in the regular immunisation schedules is made easier by the development of several combination vaccines, including IPV. Maternal antibodies and young age, often considered problematic for early initiation of IPV schedules, did not compromise optimal maintenance of seropositivity during infancy or long-term persisting antibody levels in our studies. OPV-derived, potentially pathogenic and transmissible poliovirus strains, excreted by some individuals for years, may present a problem for a blunt stopping of all polio immunisations after eradication. Our recent results suggest that locally excreted IgA might have a role in the elimination of poliovirus infection in the intestinal tissues.

Integrated cognitive-behavioral and psychodynamic psychotherapy for intimate partner violent men.

Intimate partner violence (IPV) continue to have widespread negative effects on victims, children who witness IPV, and perpetrators. Current treatments have proven to be only marginally effective in stopping or reducing IPV by men. The two most prominent treatment approaches are feminist sociocultural and cognitive-behavioral therapy (CBT). The feminist sociocultural approach has been criticized for failing to adequately consider the therapeutic alliance, personality factors, and sole focus on patriarchy as the cause for IPV, whereas CBT has been criticized for failing to attend to motivation issues in treatment protocols. This article reviews the effectiveness of current treatments for partner-violent men, examines relationship and personality variables related to IPV and its treatment, and presents an emerging IPV treatment model that combines CBT and psychodynamic therapy. The article addresses how psychodynamic therapy is integrated into the more content-based elements of CBT. PsycINFO Database Record (c) 2012 APA, all rights reserved.

Abstract: Background: Intimate partner violence (IPV) is a pervasive problem impacting individuals around the globe. The consequences of IPV extend beyond the adults in the relationship, as children witness a significant proportion of such violence. Exposure to IPV during childhood has devastating effects across multiple domains of functioning. Methods: This article reviews empirical studies of the effects of exposure to IPV by developmental stage. Results: The psychological, social, physical, and cognitive consequences of witnessing IPV are examined across development; from the impact of prenatal exposure to effects in infancy and toddlerhood, the preschool years, school-aged children, and adolescence. Conclusions: The review concludes by providing suggestions for future research based on the identified developmental variations, recommendations for developmentally-sensitive interventions for children who have witnessed IPV, and directions for policy to address the issue of violence exposure early in the lives of children.

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

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.

Adjuvants and Inactivated Polio Vaccine: A Systematic Review

PubMed Central

Hawken, Jennifer; Troy, Stephanie B.

2012-01-01

Poliomyelitis is nearing universal eradication; in 2011, there were 650 cases reported globally. When wild polio is eradicated, global oral polio vaccine (OPV) cessation followed by universal use of inactivated polio vaccine (IPV) is believed to be the safest vaccination strategy as IPV does not mutate or run the risk of vaccine derived outbreaks that OPV does. However, IPV is significantly more expensive than OPV. One strategy to make IPV more affordable is to reduce the dose by adding adjuvants, compounds that augment the immune response to the vaccine. No adjuvants are currently utilized in stand-alone IPV; however, several have been explored over the past six decades. From aluminum, used in many licensed vaccines, to newer and more experimental adjuvants such as synthetic DNA, a diverse group of compounds has been assessed with varying strengths and weaknesses. This review summarizes the studies to date evaluating the efficacy and safety of adjuvants used with IPV. PMID:23041122

This study aims to explore young men's understanding of intimate partner violence (IPV) in Ecuador, examining similarities and differences between how ordinary and activist young men conceptualize IPV against women. We conducted individual interviews and focus group discussions (FGDs) with 35 young men--five FGDs and five interviews with ordinary young men, and 11 interviews with activists--and analysed the data generated using qualitative content analysis. Among the ordinary young men the theme 'too much gender equality leads to IPV' emerged, while among the activists the theme 'gender inequality is the root of IPV'. Although both groups in our study rejected IPV, their positions differed, and we claim that this is relevant. While activists considered IPV as rooted in gender inequality, ordinary young men understood it as a response to the conflicts generated by increasing gender equality and women's attempts to gain autonomy.

Objectives Low relationship power and victimization by intimate partner violence (IPV) have been linked to HIV risks among adult females and adolescent girls. This article examines associations of IPV and relationship power with sexual-risk behaviors and whether the associations differ by gender among South African adolescents. Methods Sexual-risk behaviors (multiple partners in past 3 months; condom use at last sex), IPV, and relationship power were collected from 786 sexually experienced adolescents (mean age = 16.9) in Eastern Cape Province, South Africa during the 54-month follow-up of a HIV/STI risk-reduction intervention trial. Logistic regression examined associations of sexual-risk behaviors with IPV and relationship power and whether the associations differed by gender. Results Adolescent boys were less likely to report condom use at last sex (p=.001) and more likely to report multiple partners (p< .001). A Gender x IPV interaction (p=.002) revealed that as IPV victimization increased, self-reported condom use at last sex decreased among girls, but increased among boys. A Gender x Relationship Power interaction (p=.004) indicated that as relationship power increased, self-reported condom use at last sex increased among girls, but decreased among boys. A Gender x IPV interaction (p=.004) indicated that as IPV victimization increased, self-reports of having multiple partners increased among boys, but not among girls. As relationship power increased, self-reports of having multiple partners decreased irrespective of gender. Conclusions HIV risk-reduction interventions and policies should address gender differences in sexual-risk consequences of IPV and relationship power among adolescents and promote gender equity.

Intimate partner violence (IPV) against women is a significant public health and human rights problem. Primary care professionals play a key role in detecting and addressing this issue. The aim of this study is to determine the frequency of IPV and its associated factors in primary care by means of a screening questionnaire and to describe the main actions taken in identified cases. Cross-sectional study in 15 health centres in four autonomous regions of Spain with a total of 265 health professionals. The information was collected through the self-administered PREMIS questionnaire (Physician Readiness to Manage Intimate Partner Violence Survey), which includes variables concerning screening questions, sociodemographic factors, level of training/knowledge about IPV, perceptions and actions. A descriptive and analytical study was conducted. 67.2% of participants said they ask about IPV during consultations. The most frequent actions were: referring patients to other departments, individual counselling and information delivery. ≥21hours of training, an advanced training level, knowledge of policies and programmes and the implementation of an appropriate protocol and reference resources were all factors that increased the likelihood of investigating IPV. The asking of questions increases in line with professionals' perceived level of training in IPV and the provision of a case management protocol. Two thirds of health professional respondents said they inquire about IPV. Given the influence of training in IPV and awareness of the resources to address the issue, it is essential to continue investing in the IPV training of healthcare personnel. Copyright © 2017 SESPAS.

Following the declaration of eradication of wild poliovirus (WPV) type 2 in September 2015, trivalent oral poliovirus vaccine (tOPV) was withdrawn globally to reduce the risk for type 2 vaccine-derived poliovirus (VDPV2) transmission; all countries implemented a synchronized switch to bivalent OPV (type 1 and 3) in April 2016 (1,2). Any isolation of VDPV2 after the switch is to be treated as a potential public health emergency and might indicate the need for supplementary immunization activities (3,4). On August 9, 2016, VDPV2 was isolated from a sewage sample taken from an environmental surveillance site in Hyderabad, Sindh province, Pakistan. Possible vaccination activities in response to VDPV2 isolation include the use of injectable inactivated polio vaccine (IPV), which poses no risk for vaccine-derived poliovirus transmission. Fractional-dose, intradermal IPV (fIPV), one fifth of the standard intramuscular dose, has been developed to more efficiently manage limited IPV supplies. fIPV has been shown in some studies to be noninferior to full-dose IPV (5,6) and was used successfully in response to a similar detection of a single VDPV2 isolate from sewage in India (7). Injectable fIPV was used for response activities in Hyderabad and three neighboring districts. This report describes the findings of an assessment of preparatory activities and subsequent implementation of the fIPV campaign. Despite achieving high coverage (>80%), several operational challenges were noted. The lessons learned from this campaign could help to guide the planning and implementation of future fIPV vaccination activities.

Previous research suggests that intimate partner violence (IPV), particularly physical or sexual violence, was associated with cervical cancer. However, there is less work examining the mechanism of the relationship between IPV and cervical cancer. The purpose of this cross-sectional study was to examine psychosocial factors (e.g., stress, social support, self-esteem, and depressive symptoms) as mediators of the relationship between IPV and cervical cancer among 532 Thai women with gynecological problems. About 21.1% of participants reported any type of IPV (e.g., physical, sexual, or emotional violence) in the past year and 22.2% had cervical cancer. IPV was significantly positively associated with stress, depressive symptoms, and cervical cancer but negatively correlated with social support and self-esteem. Results from structural equation modeling indicated that not only did IPV exhibit significantly direct effects on social support, stress, and depressive symptoms, and indirect effects on self-esteem, but it also had a significant, positive, total effect on cervical cancer. IPV exhibited the significant indirect effect on cervical cancer through social support, self-esteem, stress, and depressive symptoms. The model fitted very well to the empirical data and explained 9% of variance. The findings affirmed that those psychosocial factors were mediators of the relationship between IPV and cervical cancer. Health care protocols for abused women should include screening for and treatment of IPV-related psychosocial factors. Interventions that provide social support and protect self-esteem should reduce stress and depressive symptoms among abused women, thereby reducing the risk of cervical cancer. © The Author(s) 2014.

Intimate partner violence (IPV) is a significant and largely hidden public health problem for all women and, during pregnancy, can have significant effects on the health of both mother and the unborn baby. Previous Namibian studies suggest rates of IPV as high as 36%, although few studies have been conducted in primary care. To determine the prevalence of IPV amongst women attending antenatal care. Outapi primary care clinic, Namibia. A descriptive survey administering a validated questionnaire to 386 consecutive participants. The mean age of the participants was 27.5 years (standard deviation = 6.8), 335 (86.8%) were unmarried, 215 (55.7%) had only primary school education and 237 (61.4%) were in their third trimester. Overall, 51 participants (13.2%) had HIV and 44 (11.4%) had teenage pregnancies. The reported lifetime prevalence of IPV was 39 (10.1%), the 12-month prevalence was 35 (9.1%) and the prevalence during pregnancy was 31 (8.0%). Emotional abuse was the commonest type of abuse in 27 (7.0%). The commonest specific abusive behaviour was refusing to provide money to run the house or look after the children whilst the partner spent money on his priorities (4.9%). Increased maternal age was associated with an increase in the occurrence of IPV. The reported lifetime prevalence of IPV was 10.1%, with emotional abuse being the commonest type of abuse. Increased age was associated with an increase in reported IPV. IPV is significant enough to warrant that healthcare providers develop guidelines to assist women affected by IPV in Namibia.

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
