    Maternal factors comprising of social, obstetric and anthropometric are found to influence LBW. The present study had found association between obstetric risk factors like age of the mother, parity and gravida with LBW. Similar association was also observed between maternal height, and maternal weight with LBW. However, social factors were not found to be associated with LBW. This could probably be due to RUHSA's intervention which requires a further inquiry. PMID:8244503

    Objectives. We estimated the effects of maternal depression during the postpartum year, which is often an unexpected event, on subsequent homelessness and risk of homelessness in a national sample of urban, mostly low-income mothers. Methods. We used logistic regression models to estimate associations between maternal depression during the postpartum year and both homelessness and risk of homelessness 2 to 3 years later, controlling for maternal and family history of depression, prenatal housing problems, and other covariates. Risk factors for homelessness included experiencing evictions or frequent moves and moving in with family or friends and not paying rent. Results. We found robust associations between maternal depression during the postpartum year and subsequent homelessness and risk of homelessness, even among mothers who had no history of mental illness, whose own mothers did not have a history of depressive symptoms, and who had no previous housing problems. Conclusions. This study provides robust evidence that maternal mental illness places families with young children at risk for homelessness, contributes to the scant literature elucidating directional and causal links between mental illness and homelessness, and contributes to a stagnant but important literature on family homelessness.

    Background: Over the past 10 years, research into environmental risk factors for autism has grown dramatically, bringing evidence that an array of non-genetic factors acting during the prenatal period may influence neurodevelopment. Methods: This paper reviews the evidence on modifiable preconception and/or prenatal factors that have been associated, in some studies, with autism spectrum disorder (ASD), including nutrition, substance use and exposure to environmental agents. This review is restricted to human studies with at least 50 cases of ASD, having a valid comparison group, conducted within the past decade and focusing on maternal lifestyle or environmental chemicals. Results: Higher maternal intake of certain nutrients and supplements has been associated with reduction in ASD risk, with the strongest evidence for periconceptional folic acid supplements. Although many investigations have suggested no impact of maternal smoking and alcohol use on ASD, more rigorous exposure assessment is needed. A number of studies have demonstrated significant increases in ASD risk with estimated exposure to air pollution during the prenatal period, particularly for heavy metals and particulate matter. Little research has assessed other persistent and non-persistent organic pollutants in association with ASD specifically. Conclusions: More work is needed to examine fats, vitamins and other maternal nutrients, as well as endocrine-disrupting chemicals and pesticides, in association with ASD, given sound biological plausibility and evidence regarding other neurodevelopmental deficits. The field can be advanced by large-scale epidemiological studies, attention to critical aetiological windows and how these vary by exposure, and use of biomarkers and other means to understand underlying mechanisms.

    We examined the associations of maternal parity with fetal and childhood growth characteristics and childhood cardiometabolic risk factors in a population-based prospective cohort study among 9031 mothers and their children. Fetal and childhood growth were repeatedly measured. We measured childhood anthropometrics, body fat distribution, left ventricular mass, blood pressure, blood lipids, and insulin levels at the age of 6 years. Compared with nulliparous mothers, multiparous mothers had children with higher third trimester fetal head circumference, length and weight growth, and lower risks of preterm birth and small-size-for-gestational-age at birth but a higher risk of large-size-for-gestational-age at birth (P<0.05). Children from multiparous mothers had lower rates of accelerated infant growth and lower levels of childhood body mass index, total fat mass percentage, and total and low-density lipoprotein cholesterol than children of nulliparous mothers (P<0.05). They also had a lower risk of childhood overweight (odds ratio, 0.75 [95% confidence interval, 0.63–0.88]). The risk of childhood clustering of cardiometabolic risk factors was not statistically significantly different (odds ratio, 0.82; 95% confidence interval, 0.64–1.05). Among children from multiparous mothers only, we observed consistent trends toward a lower risk of childhood overweight and lower cholesterol levels with increasing parity (P<0.05). In conclusion, offspring from nulliparous mothers have lower fetal but higher infant growth rates and higher risks of childhood overweight and adverse metabolic profile. Maternal nulliparity may have persistent cardiometabolic consequences for the offspring. PMID:24866145

    This report describes an exploratory population-based study of maternal and perinatal risk factors for childhood leukemia in Sweden. The Swedish National Cancer Registry ascertained 411 cases in successive birth cohorts from 1973 through 1984 recorded in the Swedish Medical Birth Registry. Using the latter, we matched five controls without cancer to each case by sex and month and year of birth. Mothers of children with leukemia were more likely to have been exposed to nitrous oxide anesthesia during delivery than mothers of controls (odds ratio (OR) = 1.3; 95% confidence interval (CI) = 1.0, 1.6). Children with leukemia were more likely than controls to have Down's syndrome (OR = 32.5; 95% CI = 7.3, 144.0) or cleft lip or cleft palate (OR = 5.0; 95% CI = 1.0, 24.8); to have had a diagnosis associated with difficult labor but unspecified complications (OR = 4.5; 95% CI = 1.1, 18.2) or with other conditions of the fetus or newborn (OR = 1.5; 95% CI = 1.1, 2.1), specifically, uncomplicated physiological jaundice (OR = 1.9; 95% CI = 1.2, 2.9); or to have received supplemental oxygen (OR = 2.6; 95% CI = 1.3, 1.3, 4.9). Because multiple potential risk factors were analyzed in this study, future studies need to check these findings. The authors did not confirm the previously reported higher risks for childhood leukemia associated with being male, having a high birth weight, or being born to a woman of advanced maternal age.

    A total of 8260 children between the ages of 6-59 months were analyzed to identify the risk factors associated with childhood anaemia in Ethiopia. The overall mean (SD/standard deviation) haemoglobin (Hgb) level among the under-five children was 10.7 (2.2) g/dl and 50.3% were anaemic. Childhood anaemia demonstrated an increasing trend with maternal anaemia levels of mild, moderate and severe anaemia: odds ratio of 1.82, 2.16 and 3.73 respectively (p< 0.01). Children whose mothers had no formal education were 1.38 times more likely to be anaemic (p<0.01). The poorest and poorer wealth index groups had 1.52 and 1.25 increased odds of childhood anaemia respectively (p< 0.01). Childhood anaemia in Ethiopia is a severe public health problem. Maternal anaemia and socio-economic status were found to be associated with anaemia in children. A holistic approach of addressing mothers and children is of paramount importance. PMID:24069773

    BACKGROUND Although associations between maternal parity and birth defects have been observed previously, few studies have focused on the possibility that parity is an independent risk factor for birth defects. We investigated the relation between levels of parity and a range of birth defects, adjusting each defect group for the same covariates. METHODS We included infants who had an estimated delivery date between 1997 and 2007 and participated in the National Birth Defects Prevention Study, a multisite case-control study. Cases included infants or fetuses belonging to 38 phenotypes of birth defects (n = 17,908), and controls included infants who were unaffected by a major birth defect (n = 7173). Odds ratios (ORs) were adjusted for 12 covariates using logistic regression. RESULTS Compared with primiparous mothers, nulliparous mothers were more likely to have infants with amniotic band sequence, hydrocephaly, esophageal atresia, hypospadias, limb reduction deficiencies, diaphragmatic hernia, omphalocele, gastroschisis, tetralogy of Fallot, and septal cardiac defects, with significant ORs (1.2 to 2.3). Compared with primiparous mothers, multiparous mothers had a significantly increased risk of omphalocele, with an OR of 1.5, but had significantly decreased risk of hypospadias and limb reduction deficiencies, with ORs of 0.77 and 0.77. CONCLUSIONS Nulliparity was associated with an increased risk of specific phenotypes of birth defects. Most of the phenotypes associated with nulliparity in this study were consistent with those identified by previous studies. Research into biologic or environmental factors that are associated with nulliparity may be helpful in explaining some or all of these associations. PMID:22371332

    Background Scarce evidence is available on the potential cardiovascular abnormalities associated with some common gestational complications. We aimed to analyze the potential maternal cardiac alterations related to gestational complications, including body mass index (BMI) >25 kg/m2, gaining excessive weight, or developing antenatal depression. Methods The design of this study was a secondary analysis of a randomized controlled trial. Echocardiography was performed to assess cardiovascular indicators of maternal hemodynamic, cardiac remodeling and left ventricular (LV) function in 59 sedentary pregnant women at 20 and 34 weeks of gestation. Results Starting pregnancy with a BMI >25 kg/m2, gaining excessive weight, and developing antenatal depression had no cardiovascular impact on maternal health (P value >0.002). Depressed women were more likely to exceed weight gain recommendations than non-depressed women (P value <0.002). Conclusions The evaluated gestational complications seem not to induce cardiovascular alterations in hemodynamic, remodeling and LV function indicators. However, developing antenatal depression increases the risk of an excessive weight gain. This finding is potentially important because excessive weight gain during pregnancy associates with a higher risk of cardiovascular diseases (CVD) later in life. PMID:27500154

    The aim of this study was to examine the pathways that link mothers’ early life socioeconomic status (SES) and mothers’ experience of childhood maltreatment with birth weight among their later born offspring. Data were drawn from a nationally representative longitudinal survey of school-aged respondents, initially enrolled during adolescence in Wave I (1994–1995) and Wave II (1996) of the National Longitudinal Study of Adolescent Health and followed-up in adulthood in Wave III (2001–2002). Data on offspring birth weight were obtained from nulliparous females (N=1,897) who had given birth between Waves II and III. Analyses used structural equation modeling to examine the extent to which early life maternal risk predicted offspring birth weight, and demonstrated that maternal childhood SES and maternal childhood maltreatment predicted offspring birth weight through several mediated pathways. First, maternal adolescent substance use and prenatal cigarette use partially mediated the association between maternal childhood SES and offspring birth weight. Second, maternal adolescent depressive symptoms and adult SES partially mediated the association between maternal childhood SES and offspring birth weight. Third, adult SES partially mediated the association between maternal childhood SES and offspring birth weight. Fourth, maternal adolescent substance use and prenatal cigarette use partially mediated the association between maternal childhood maltreatment and offspring birth weight. Finally, maternal adolescent depressive symptoms and adult SES partially mediated the association between maternal childhood maltreatment and offspring birth weight. To our knowledge, this is the first study to identify maternal childhood maltreatment as an early life risk factor for offspring birth weight among a nationally representative sample of young women, and to demonstrate the mechanisms that link childhood SES and maltreatment to offspring birth weight.

    Background Maternal mortality continues to have devastating impacts in many societies, where it constitutes a leading cause of death, and thus remains a core issue in international development. Nevertheless, individual determinants of maternal mortality are often unclear and subject to local variation. This study aims to characterise individual risk factors for maternal mortality in Tigray, Ethiopia. Methods A community-based case-control study was conducted, with 62 cases and 248 controls from six randomly-selected rural districts. All maternal deaths between May 2012 and September 2013 were recruited as cases and a random sample of mothers who delivered in the same communities within the same time period were taken as controls. Multiple logistic regression was used to identify independent determinants of maternal mortality. Results Four independent individual risk factors, significantly associated with maternal death, emerged. Women who were not members of the voluntary Women’s Development Army were more likely to experience maternal death (OR 2.07, 95% CI 1.04–4.11), as were women whose husbands or partners had below-median scores for involvement during pregnancy (OR 2.19, 95% CI 1.14–4.18). Women with a pre-existing history of other illness were also at increased risk (OR 5.58, 95% CI 2.17–14.30), as were those who had never used contraceptives (OR 2.58, 95% CI 1.37–4.85). Previous pregnancy complications, a below-median number of antenatal care visits and a woman’s lack of involvement in health care decision making were significant bivariable risks that were not significant in the multivariable model. Conclusions The findings suggest that interventions aimed at reducing maternal mortality need to focus on encouraging membership of the Women’s Development Army, enhancing husbands’ involvement in maternal health services, improving linkages between maternity care and other disease-specific programmes and ensuring that women with previous

    2014-01-01

    Background Previous studies have found associations between maternal and family factors and child eating disorder symptoms. However, it is not clear whether family factors predict eating disorder symptoms specifically, or relate to more general child psychopathology, of which eating disorder symptoms may be one component. This study aimed to identify maternal and family factors that may predict increases or decreases in child eating disorder symptoms over time, accounting for children’s body mass index z-scores and levels of general psychological distress. Methods Participants were 221 mother-child dyads from the Childhood Growth and Development Study, a prospective cohort study in Western Australia. Participants were assessed at baseline, 1-year follow-up and 2-year follow-up using interview and self-report measures. Children had a mean age of 10 years at baseline and 46% were male. Linear mixed models and generalised estimating equations were used to identify predictors of children’s eating disorder symptoms, with outcome variables including a global index of eating disorder psychopathology, levels of dietary restraint, levels of emotional eating, and the presence of loss of control (‘binge’) eating. Results Children of mothers with a current or past eating disorder reported significantly higher levels of global eating disorder symptoms and emotional eating than other children, and mothers with a current or past eating disorder reported significantly more concern about their children’s weight than other mothers. Maternal concern about child weight, rather than maternal eating disorder symptoms, was significant in predicting child eating disorder symptoms over time. Family exposure to stress and low maternal education were additional risk factors for eating disorder symptoms, whilst child-reported family satisfaction was a protective factor. Conclusions After adjusting for relevant confounding variables, maternal concern about child weight, children

    We examined for a regional sample of the New Zealand population, the relationship between maternal height and an increased risk of emergency Caesarean section due to arrested labour, to identify a height below which the risk of Caesarean section increases markedly and to quantify the risk of a Caesarean section for a range of maternal heights. The data of nulliparous singleton pregnancies over the period 1994-1998 was sorted into 2 study groups, one resulting in emergency Caesarean section for arrested labour and the other a group of women who had normal vaginal delivery requiring no intervention. The means and standard deviations of these 2 groups were found and 99% confidence intervals calculated. They were analysed for statistical difference and then a logistical regression calculation tried to identify a height at which the risk of a Caesarean section increased suddenly. There were 81 women in the Caesarean section group and 997 in the normal vaginal delivery group. Mean heights and confidence intervals were 161.0 cm (158.9-163.1) and 164.6 cm (164.0-165.2) respectively. There was a statistically significant difference between these means (p<0.001) but logistic regression analysis showed that risk of Caesarean section increased gradually with decreasing height, and even then did not reach more than 30% risk until a height of less than 140 cm. Low maternal height was associated with increased risk of Caesarean section due to labour arrest. Because the likelihood of having a normal vaginal delivery was still very good (>80 %) at modest degrees of short stature, this risk factor alone is unlikely to affect management. However the combination of other risk factors with maternal height may be of clinical use. PMID:10755767

    Background: Macrosomia is defined as birth-weight over 4,000 g irrespective of gestational age and affects 3-15% of all pregnancies. Aim The present study aimed to determine the relationship between mother's characteristics and macrosomic births and also compare macrosomic and normal newborns regarding the maternal and offspring complications of diabetes during pregnancy. Subjects and Methods: In this case control study, among the 420 consecutive births occurring in public and private hospitals of Shiraz, Iran from October 2006 to March 2007, the data of 32 macrosomic and 128 normal newborns were analyzed using t-test and chi square in bivariate and logistic regression in multivariate model. Results: The mean (SD) of neonate weight, height, and head size was 3323.4 (709), 48.95 (3.2), and 34.9 (1.8), respectively. Regression analysis showed that gestational diabetes (Odds Ratio (OR): 11.9, Confidence Interval (CI): 4.6-30.3), preeclampsia in the pregnancy period due to diabetes (OR: 3.81, CI: 1.1-13.2), and macrosomic birth history (OR: 3.3, CI: 1.04-10.4) were the main predictors of macrosomia. Moreover, macrosomia increased neonate hypoglycemia (OR: 4.7, CI: 1.4-15.8) and section delivery (OR: 4.1, CI: 1.27-13.1). Conclusion: Gestational diabetes, preeclampsia due to diabetes, and history of macrosomic birth were the main predictors of macrosomia. Moreover, macrosomia increased some delivery complications for both mothers and newborns. PMID:24380006

    Background Maternal risk factors for fetal alcohol spectrum disorders (FASD) in Italy and Mediterranean cultures need clarification, as there are few studies and most are plagued by inaccurate reporting of antenatal alcohol use. Methods Maternal interviews (n=905) were carried out in a population-based study of the prevalence and characteristics of FASD in the Lazio region of Italy which provided data for multivariate case control comparisons and multiple correlation models. Results Case control findings from interviews seven years post-partum indicate that mothers of children with FASD are significantly more likely than randomly-selected controls or community mothers to: be shorter; have higher body mass indexes (BMI); be married to a man with legal problems; report more drinking three months pre-pregnancy; engage in more current drinking and drinking alone; and have alcohol problems in her family. Logistic regression analysis of multiple candidate predictors of a FASD diagnosis indicates that alcohol problems in the child’s family is the most significant risk factor, making a diagnosis within the continuum of FASD 9 times more likely (95% C.I. = 1.6 to 50.7). Sequential multiple regression analysis of the child’s neuropsychological performance also identifies alcohol problems in the child’s family as the only significant maternal risk variable (p<.001) when controlling for other potential risk factors. Conclusions Underreporting of prenatal alcohol use has been demonstrated among Italian and other Mediterranean antenatal samples, and it was suspected in this sample. Nevertheless, several significant maternal risk factors for FASD have been identified. PMID:25456331

    2015-01-01

    Background The aims of this study were to assess the levels of knowledge, attitudes and behaviors of women about the main maternal risk factors in pregnancy and to identify the factors linked to the main outcomes of interest. Materials and Methods A cross-sectional survey was conducted in 513 pregnant women randomly selected from the gynecological ambulatory services of five hospitals located in Naples, Italy. Results Only 42% of women correctly knew all the main maternal risk factors in pregnancy (alcohol, smoking, passive smoking and obesity). Only 21.7% of women were very worried about causing harm to the fetus or child with their risk behaviors, and 22.3% of women reported smoking during pregnancy. Approximately one-third of women (28.9%) reported regularly drinking alcohol before pregnancy and 74.8% of these women reported stopping drinking alcohol during pregnancy. However, only 27.3% of women who were drinking alcohol during pregnancy had the intention of stopping. Only 43.7% of women indicated that during ambulatory gynecological examinations they received information from physicians about the possible damage resulting from all the main risk factors in pregnancy (alcohol, smoking, passive smoking and obesity). Conclusion The results indicate that pregnant women lack knowledge regarding the main maternal risk factors. Pregnant women claim to receive little information during gynecological examinations and, therefore, some continue to smoke and drink alcohol during pregnancy. Our results suggest an urgent need for the design of interventions to improve women’s levels of knowledge and to promote appropriate behavior in relation to the major risk factors in pregnancy.

    Newborn diseases increase neonatal mortality rates, so a literature review was conducted to establish the risk factors related to maternal and peripartum morbidity affecting the newborn. We searched the following electronic databases: Cumed, EBSCO, LILACS, IBECS and PubMed/MEDLINE. We used specific terms and Boolean operators in Spanish, Portuguese and English. We included longitudinal and cross-sectional descriptive studies, as well as case-control and cohort studies, systematic reviews and meta-analysis, spanning from 2010 to 2015 that responded the topic of interest. The included studies show that multiple maternal and perinatal conditions are risk factors for significant increase of neonatal morbidity, which are described in this narrative review. PMID:26247448

    Objectives The aim of this analysis was to quantify the risk factors associated with maternal morbidity among women in Victoria, Australia, focusing particularly on sociodemographic factors. Design Case–control analysis. Participants Data on all maternities in Victoria from 1 January 2006 to 31 December 2008. Methods A case–control analysis was conducted using unconditional logistic regression to calculate adjusted ORs (aORs). Cases were defined as all women noted to have had a severe complication during the index pregnancy. Severe maternal morbidity was defined by the validated, composite Australian Maternal Morbidity Outcome Indicator. Socioeconomic position was defined by Socio-Economic Indices for Areas (SEIFA), specifically the Index of Relative Socioeconomic Disadvantage (IRSD), and other variables analysed were age, parity, Indigenous background, multiple pregnancy, country of birth, coexisting medical condition, previous caesarean section, spontaneous abortion or ectopic pregnancy. Results The study population comprised 211 060 women, including 1119 cases of severe maternal morbidity (0.53%). Compared with the highest IRSD quintile, the aOR for the 2nd quintile was 1.23 (95% CI 1.03 to 1.49), 0.98 (95% CI 0.79 to 1.21) for the 3rd quintile, 1.55 (95% CI 1.28 to 1.87) for the 4th and 1.21 (95% CI 1.00 to 1.47) for the lowest (most deprived) quintile. Indigenous status was associated with twice (aOR 2.02; 95% CI 1.32 to 3.09) the odds of being a case. Other risk factors for severe maternal morbidity were age ≥35 years (aOR 1.22; 95% CI 1.04 to 1.44), coexisting medical condition (aOR 1.39; 95% CI 1.16 to 1.65), multiple pregnancy (aOR 2.30; 95% CI 1.71 to 3.10), primiparity (aOR 1.36; 95% CI 1.18 to 1.57), previous caesarean section (aOR 1.79; 95% CI 1.53 to 2.10) and previous spontaneous miscarriage (aOR 1.25; 95% CI 1.08 to 1.44). Conclusions The findings from Victoria strongly suggest that social disadvantage needs to be acknowledged and further

    Emerging evidence from epidemiological studies supports the notion that maternal folate status regulated by dietary and genetic factors early in pregnancy may influence the risk of autism spectrum disorders (ASD). In this review, we provide an overview of what is known about the role of folate in the aetiology of neurodevelopmental disorders; summarise relevant biological, genetic and epigenetic mechanisms; and synthesise the evidence from human observational studies and randomised controlled trials that have examined the relationship between maternal folate and ASD or related traits. Much of the existing literature on this topic is subject to limitations such as potential confounding by healthy behaviours and other dietary factors, and exposure assessed within limited exposure windows. As the existing evidence is inconclusive, further research remains to be conducted in order to verify this hypothesis. Complete assessment of maternal functional folate status through the pre- and peri-conceptional periods requires biological measurement of folate, vitamin B12 and homocysteine and genetic variants involved in one-carbon metabolism and epigenetic mechanisms. In addition to more complete assessment of maternal functional folate status, careful consideration of potential confounding is warranted. PMID:26243379

    Depression among mothers with young children is an important public health issue that not only has implications for their own well-being, but can also potentially affect their children's health and developmental trajectories. This study explored the extent to which maternal depression is a risk factor for inadequate housing conditions related to utilities, a noteworthy risk factor for poor child health. Using data on 2965 mothers and children from a national urban cohort of U.S. births in 1998-2000, we estimated multivariate logistic regression models of associations between maternal depression during the postpartum year and a U.S. Department of Housing and Urban Development (HUD) measure of severely inadequate housing due to heating issues, as well as a broader measure of energy insecurity that encompasses various types of utility problems. We also considered outcomes that incorporated housing instability and food insecurity in conjunction with housing inadequacy. Mothers who experienced depression had about 60% higher odds of experiencing severely inadequate housing due to heat (OR: 1.57) and 70% higher odds of experiencing energy insecurity (OR: 1.69) compared to mothers who did not experience depression. Maternal depression was even more strongly associated with multiple hardships in the forms of housing inadequacy plus housing instability and/or food insecurity than it was with housing inadequacy. This study provides robust evidence that maternal depression is a risk factor for inadequate housing and multiple hardships during a critical period of children's development. The findings suggest that policy efforts should not occur in mental health, housing, and food security silos. PMID:26708243

    Objective. The objective of the study was to examine the pattern of low birth weight LBW, maternal complications, and its related factors among Arab women in Qatar. Design. This is a prospective hospital-based study. Setting. The study was carried out in Women's Hospital, Doha. Subjects and Methods. Pregnant women in their third trimester were identified in the log book of Women's Hospital and recruited into the study during first week of January 2010 to July 2011. Only 1674 (out of 2238) Arab women (74.7%) consented to participate in this study. Data on clinical and biochemistry parameters were retrieved from medical records. Follow-up data on neonatal outcome was obtained from labor room register. Results. The incidence of LBW (<2500 g) was 6.7% among Arab women during 2010 in Qatar. Distribution of gestational diabetes mellitus (GDM), antepartum hemorrhage (APH), maternal anemia, premature rupture of membrane (PROM), maternal occupation, parity, sheesha smoking, and parental consanguinity were significantly different (P < 0.05) between mothers of LBW and normal birth weight NBW (≥2500 g) babies. Multivariable logistic regression analysis revealed that previous LBW, consanguinity, parity, smoking shesha, GDM, APH, anemia, PROM, maternal occupation, and housing condition were significantly associated with LBW adjusting for gestational age. Conclusion. Maternal complications such as GDM, APH, anemia, PROM, and smoking shesha during pregnancy are significantly increasing the risk of LBW outcome. Screening and prompt treatment for maternal complications and health education for smoking cessation during routine antenatal visits will help in substantial reduction of LBW outcome. PMID:22991672

    Background Environmental exposures that occur in utero and during early life may contribute to the development of childhood asthma through alteration of the human microbiome. The objectives of this study were to estimate the cumulative effect and relative importance of environmental exposures on the risk of childhood asthma. Methods We conducted a population-based birth cohort study of mother-child dyads who were born between 1995 and 2003 and were continuously enrolled in the PRIMA (Prevention of RSV: Impact on Morbidity and Asthma) cohort. The individual and cumulative impact of maternal urinary tract infections (UTI) during pregnancy, maternal colonization with group B streptococcus (GBS), mode of delivery, infant antibiotic use, and older siblings at home, on the risk of childhood asthma were estimated using logistic regression. Dose-response effect on childhood asthma risk was assessed for continuous risk factors: number of maternal UTIs during pregnancy, courses of infant antibiotics, and number of older siblings at home. We further assessed and compared the relative importance of these exposures on the asthma risk. In a subgroup of children for whom maternal antibiotic use during pregnancy information was available, the effect of maternal antibiotic use on the risk of childhood asthma was estimated. Results Among 136,098 singleton birth infants, 13.29% developed asthma. In both univariate and adjusted analyses, maternal UTI during pregnancy (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.18, 1.25; adjusted OR [AOR] 1.04, 95%CI 1.02, 1.07 for every additional UTI) and infant antibiotic use (OR 1.21, 95%CI 1.20, 1.22; AOR 1.16, 95%CI 1.15, 1.17 for every additional course) were associated with an increased risk of childhood asthma, while having older siblings at home (OR 0.92, 95%CI 0.91, 0.93; AOR 0.85, 95%CI 0.84, 0.87 for each additional sibling) was associated with a decreased risk of childhood asthma, in a dose-dependent manner.

    2015-01-01

    Background Because large, prospective, population-based data sets describing maternal outcomes are typically not available in low- and middle-income countries, it is difficult to monitor maternal mortality rates over time and to identify factors associated with maternal mortality. Early identification of risk factors is essential to develop comprehensive intervention strategies preventing pregnancy-related complications. Our objective was to describe maternal mortality rates in a large, multi-country dataset and to determine maternal, pregnancy-related, delivery and postpartum characteristics that are associated with maternal mortality. Methods We collected data describing all pregnancies from 2010 to 2013 among women enrolled in the multi-national Global Network for Women’s and Children’s Health Research Maternal and Neonatal Health Registry (MNHR). We reported the proportion of mothers who died per pregnancy and the maternal mortality ratio (MMR). Generalized linear models were used to evaluate the relationship of potential medical and social factors and maternal mortality and to develop point and interval estimates of relative risk associated with these factors. Generalized estimating equations were used to account for the correlation of outcomes within cluster to develop appropriate confidence intervals. Results We recorded 277,736 pregnancies and 402 maternal deaths for an MMR of 153/100,000 live births. We observed an improvement in the total MMR from 166 in 2010 to 126 in 2013. The MMR in Latin American sites (91) was lower than the MMR in Asian (178) and African sites (125). When adjusted for study site and the other variables, no formal education (RR 3.2 [1.5, 6.9]), primary education only (RR 3.4 [1.6, 7.5]), secondary education only (RR 2.5 [1.1, 5.7]), lack of antenatal care (RR 1.8 [1.2, 2.5]), caesarean section delivery (RR 1.9 [1.3, 2.8]), hemorrhage (RR 3.3 [2.2, 5.1]), and hypertensive disorders (RR 7.4 [5.2, 10.4]) were associated with higher

    Summary Background Severe maternal morbidity (SMM) is a serious health condition potentially resulting in death without immediate medical attention, including organ failure, obstetric shock, and elcampsia. SMM affects 20,000 US women every year; however, few population-based studies have examined SMM risk factors. Methods We conducted a population-based case-control study linking birth certificate and hospital discharge data from Washington State (1987–2008), identifying 9,485 women with an antepartum, intrapartum, or postpartum SMM with ≥3-day hospitalization or transfer from another facility and 41,112 random controls. Maternal age, race, smoking during pregnancy, parity, preexisting medical condition, multiple birth, prior cesarean delivery, and BMI were assessed as risk factors with logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI), adjusted for education and delivery payer source. Results Older women [35–39: OR 1.65 CI 1.52, 1.79; 40+: OR 2.48 CI 2.16, 2.81], non-white women [Black: OR 1.82 CI 1.64, 2.01; American Indian: OR 1.52 CI 1.32, 1.73; Asian/Pacific Islander: OR 1.30 CI 1.19, 1.41; Hispanic: OR 1.17 CI 1.07, 1.27], and women at parity extremes [OR 1.83 CI 1.72, 1.95, nulliparous; OR 1.34 CI 1.23, 1.45, parity 3+] were at greater risk of SMM. Women with a preexisting medical condition [OR 2.10 CI 1.88, 2.33], a multiple birth [OR 2.54 CI 2.26, 2.82], and a prior cesarean delivery [OR 2.08 CI 1.93, 2.23] were also at increased risk. Conclusion The risk factors identified are not modifiable at the individual level; therefore, provider and system-level factors may be the most appropriate target for preventing SMM. PMID:23061686

    Epidemiological studies have evaluated the association between maternal methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C and methionine synthase reductase (MTRR) A66G polymorphisms and risk of neural tube defects (NTDs) in offspring. However, the results from the published studies on the association between these three polymorphisms and NTD risk are conflicting. To derive a clearer picture of association between these three maternal polymorphisms and risk of NTD, we performed meta-analysis. A comprehensive search was conducted to identify all case-control studies of maternal MTHFR and MTRR polymorphisms and NTD risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. Overall, we found that maternal MTHFR C677T polymorphism (OR(TvsC) =1.20; 95% CI = 1.13-1.28) and MTRR A66G polymorphism (OR(GvsA) = 1.21; 95% CI = 0.98-1.49) were risk factors for producing offspring with NTD but maternal MTHFR A1298C polymorphism (OR(CvsA) = 0.91; 95% CI = 0.78-1.07) was not associated with NTD risk. However, in stratified analysis by geographical regions, we found that the maternal C677T polymorphism was significantly associated with the risk of NTD in Asian (OR(TvsC) = 1.43; 95% CI: 1.05-1.94), European (OR(TvsC) = 1.13; 95% CI: 1.04-1.24) and American (OR(TvsC) = 1.26; 95% CI: 1.13-1.41) populations. In conclusion, present meta-analysis supports that the maternal MTHFR C677T and MTRR A66G are polymorphisms contributory to risk for NTD. PMID:25005003

    OBJECTIVES: The present study was carried out in seven maternity hospitals to determine the prevalence of maternal syphilis at the time of delivery and the associated risk factors, to conduct a pilot project of rapid syphilis testing in hospital laboratories, to assure the quality of syphilis testing, and to determine the rate of congenital syphilis in infants born to women with syphilis at the time of delivery--all of which would provide baseline data for a national prevention programme in Bolivia. METHODS: All women delivering either live-born or stillborn infants in the seven participating hospitals in and around La Paz, El Alto, and Cochabamba between June and November 1996 were eligible for enrolment in the study. FINDINGS: A total of 61 out of 1428 mothers (4.3%) of live-born infants and 11 out of 43 mothers (26%) of stillborn infants were found to have syphilis at delivery. Multivariate analysis showed that women with live-born infants who had less than secondary-level education, who did not watch television during the week before delivery (this was used as an indicator of socioeconomic status), who had a previous history of syphilis, or who had more than one partner during the pregnancy were at increased risk of syphilis. While 76% of the study population had received prenatal care, only 17% had syphilis testing carried out during the pregnancy; 91% of serum samples that were reactive to rapid plasma reagin (RPR) tests were also reactive to fluorescent treponemal antibody-absorption (FTA-ABS) testing. There was 96% agreement between the results from local hospital laboratories and national reference laboratories in their testing of RPR reactivity of serum samples. Congenital syphilis infection was confirmed by laboratory tests in 15% of 66 infants born to women with positive RPR and FTA-ABS testing. CONCLUSION: These results indicate that a congenital syphilis prevention programme in Bolivia could substantially reduce adverse infant outcomes due to this

    This study examines whether maternal vitamin D deficiency is a risk factor for infantile autism disease (IAD). We used epidemiologic data seasonal variation of birth rates and prevalence of IAD for cohorts born before 1985. For seven studies reporting spring-to-summer excess birth rates for IAD, the season progressed from broad near 30 degrees N latitude, spring/summer in midlatitudes, to winter at the highest latitude. Also, using data from 10 studies, we found a strong effective latitudinal (related to wintertime solar ultraviolet B radiation) increase in IAD prevalence. These findings are consistent with maternal vitamin D deficiency's being a risk factor for IAD, possibly by affecting fetal brain development as well as possibly by affecting maternal immune system status during pregnancy. Further investigation of this hypothesis is warranted. PMID:20592795

    We examined whether polymorphisms in the methylenetetrahydrofolate dehydrogenase (MTHFD) and transcobalamin (TC) genes, which are involved in folate metabolism, affect maternal risk for Down syndrome. We investigated 76 Down syndrome mothers and 115 control mothers from Bengbu, China. Genomic DNA was isolated from the peripheral lymphocytes. Polymerase chain reaction and restriction fragment length polymorphism were used to examine the polymorphisms of MTHFD G1958A and TC C776G. The frequencies of the polymorphic alleles were 24.3 and 19.1% for MTHFD 1958A, 53.9 and 54.2% for TC 776G, in the case and control groups, respectively. No significant differences were found between two groups in relation to either the allele or the genotype frequency for both polymorphisms. However, when gene-gene interactions between these two polymorphisms together with previous studied C677T and A1298C polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene were analyzed, the combined MTHFR 677CT/TT and MTHFD 1958AA/GA genotype was found to be significantly associated with the risk of having a Down syndrome child [odds ratio (OR) = 3.11; 95% confidence interval (95%CI) = 1.07-9.02]. In addition, the combined TC 776CG and MTHFR 677TT genotype increased the risk of having a child with Down syndrome 3.64-fold (OR = 3.64; 95%CI = 1.28-10.31). In conclusion, neither MTHFD G1958A nor TC C776G polymorphisms are an independent risk factor for Down syndrome. However, the combined MTHFD/MTHFR, TC/MTHFR genotypes play a role in the risk of bearing a Down syndrome child in the Chinese population. PMID:24668664

    Developmental dysplasia of the hip (DDH) is a wide-spectrum disease with a multifactorial etiology and, despite its prevalence, no definitive etiology has yet been established. The aim of this study was to investigate new risk factors for DDH by evaluating newly defined potential risk factors. A total of 71 infants were separated into 2 groups:Group I, 28 female first-born infants diagnosed with DDH and their mothers;and Group II, 43 healthy female first-born infants and their mothers. The maternal height and weight before pregnancy, infant height and weight at birth, and body mass index (BMI) of both mother and infant were determined. Calculations were made of the ratios between these parameters. Of the examined risk factors, only maternal height and the ratio of maternal height to infant BMI (MH/I-BMI) were found to be significant for DDH in infants. In conclusion, the results of this study show that a short maternal height and a low MH/I-BMI increase the risk of DDH. Further studies with a larger series are necessary to confirm these results.

    Studies investigating the association between maternal adiposity and risk of pre-eclampsia showed contradictory results. Therefore, we performed a meta-analysis of prospective cohort studies to estimate the effect of maternal adiposity on pre-eclampsia. We reviewed 1,286 abstracts and finally included 29 prospective cohort studies with 1,980,761 participants and 67,075 pre-eclampsia events. We pooled data with a random-effects model, and obtained risk estimates for five predetermined bodyweight groups: low, normal-weight (reference), overweight, obese and severely obese. In the cohort studies that unadjusted for pre-eclampsia risk factors, the pooled unadjusted relative risks (RR) with 95% confidence intervals (95%CI) for pre-eclampsia of overweight, obese and severely obese women were 1.58 (95% CI 1.44-1.72, P < 0.001), 2.68 (95% CI 2.39-3.01, P < 0.001) and 3.12 (95% CI 2.24-4.36, P < 0.001), respectively. In those cohorts that adjusted for pre-eclampsia risk factors, the pooled unadjusted RRs for pre-eclampsia of overweight, obese and severely obese women were 1.70 (95% CI 1.60-1.81, P < 0.001), 2.93 (95% CI 2.58-3.33, P < 0.001) and 4.14 (95% CI 3.61-4.75, P < 0.001), respectively. Sensitivity analysis showed maternal adiposity was associated with increased risk of pre-eclampsia in both nulliparous and multiparas women. In conclusion, overweight or obese pregnant women have a substantially increased risk of pre-eclampsia, and maternal adiposity is an independent risk factor of pre-eclampsia. PMID:23530552

    Background: To assess the maternal risk factors associated with low birth weight (LBW) neonates at a tertiary hospital, Nanded, Maharashtra. Materials and Methods: This study was carried out in a tertiary care hospital in Nanded city of Maharashtra between January 2014 and July 2014 among 160 cases (LBW-birth weight ≤2499 g) and 160 controls (normal birth weight-birth weight >2499. Data collection was done by using predesigned questionnaire and also related health documents were checked and collected the expected information during the interview after obtaining informed consent from mothers. The data were analyzed by Epi Info 7 Version. Results: The present study found the significant association among gestational age, sex of baby, type of delivery, maternal age, religion, education of mother and husband, occupation of mother and husband, type of family, maternal height, weight gain, hemoglobin level, planned/unplanned delivery, bad obstetric history, interval between pregnancies, previous history of LBW, underlying disease, tobacco chewing, timing of first antenatal care (ANC) visit, total number of ANC visit, and iron and folic acid (IFA) tablets consumption with LBW. No significant association was found among maternal age, residence, caste, consanguinity of marriage, socioeconomic status, gravida, birth order, multiple pregnancy, and smoking with LBW in our study. Conclusion: It was concluded that hemoglobin level, weight gain during pregnancy, gestational age, planned/unplanned delivery, bad obstetric history, and IFA tablets consumption during pregnancy were independent risk factors for LBW.

    This longitudinal study examined paternal, perceived maternal, and youth risk factors at Time 1 (T1) (e.g., substance use, violent victimization, parental rules) as predictors of the stage of substance use in the adolescent child at Time 2 (T2). Participants (N = 296) consisted of drug-abusing fathers and one of their adolescent children, aged 12 to 20 years. Fathers and youths were each administered structured interviews separately and in private. Adolescents were re-interviewed approximately one year later. Pearson correlation analyses showed that the paternal, perceived maternal, and youth risk factors were significantly related to adolescent stage of substance use at T2. With an increase in risk factors, there was an increase in T2 stage of substance use in the child. Findings imply that father-oriented treatment programs should focus on how paternal behaviors, such as illegal drug use, inadequate parenting skills, and a poor father-child relationship contribute to youth problem behaviors, including alcohol, tobacco, and illicit drug use.

    Background Eating disorder behaviours begin in adolescence. Few longitudinal studies have investigated childhood risk and protective factors. Aims To investigate the prevalence of eating disorder behaviours and cognitions and associated childhood psychological, physical and parental risk factors among a cohort of 14-year-old children. Method Data were collected from 6140 boys and girls aged 14 years. Gender-stratified models were used to estimate prospective associations between childhood body dissatisfaction, body mass index (BMI), self-esteem, maternal eating disorder and family economic disadvantage on adolescent eating disorder behaviours and cognitions. Results Childhood body dissatisfaction strongly predicted eating disorder cognitions in girls, but only in interaction with BMI in boys. Higher self-esteem had a protective effect, particularly in boys. Maternal eating disorder predicted body dissatisfaction and weight/shape concern in adolescent girls and dieting in boys. Conclusions Risk factors for eating disorder behaviours and cognitions vary according to gender. Prevention strategies should be gender-specific and target modifiable predictors in childhood and early adolescence. PMID:26206865

    This study was carried out to screen children aged 16-30 months, attending pediatric outpatient department of JIPMER, Puducherry, during June to August 2014, for ASD using modified checklist for autism in toddlers-revised (MCHAT-R) and to find association between maternal, birth and postnatal risk factors with risk of ASD. A total of 350 mother-child pairs with children aged between 16 and 30 months were recruited. M-CHAT-R was administered to all mothers to screen for ASD along with risk checklist. Based on screen result children were classified as ASD (high risk) and no ASD (low and medium risk) group. The association between risk factors and screen positivity for ASD was studied using odds ratio. According to our study, 33 (9.4%) screened positive for ASD. Mean age was 21 months. High mean paternal age at birth (P value 0.025), need for resuscitation at birth (OR 3.4, 95% CI 1.47-8.10), NICU stay >12h (OR 4.7, 95% CI 2.26-9.94), late initiation of breastfeeding (OR 3.9, 95% CI 1.83-8.39), neonatal seizures (OR 11.8, 95% CI 5.38-26.25) were associated with screen positivity for ASD. After adjusting for confounding, neonatal seizures, and maternal concern about child development were associated with increased odds of screening positive for ASD whereas exclusive breast feeding in the first 6 months of life is associated with decreased odds. Screening for ASD in children with above risk factors might help in early initiation of remedial interventions. PMID:27520889

    Although "late preterm" (LP) newborns (33-36 weeks of gestational age) represent more than 70% of all preterm labors, little is known about the relation between certain risk factors and developmental outcomes in LP compared to "very preterm" (≤32 weeks) children (VP). This study investigates: (1) LP and VP infants' development at 12 months of corrected age (CA) using the Bayley Scales of Infant Development - 3rd Edition (BSID-III); (2) correlation between BSID-III performances and maternal stress (using Parenting Stress Index-Short Form, PSI-SF) among LP and VP at 12 months CA; and (3) the link between known neonatal and demographic risk factors and developmental outcomes of LP and VP infants. For both LP and VP infants the Mean Cognitive (LP: 102.69±7.68; VP: 103.63±10.68), Language (LP: 96.23±10.08; VP: 99.10±10.37) and Motor (LP: 91.11±10.33; VP: 93.85±10.17) composite scores were in the normal range, without significant differences between the groups. Correlations between PSI-SF and BSID-III showed that in the VP group (but not LP), Language score was negatively related to the PSI-SF 'Difficult Child' scale (r=-.34, p<.05). Regression models revealed that cognitive performance was significantly predicted by physical therapy in LP and by cesarean section in VP infants. For VP only maternal education and length of stay predicted Language score, whereas physical therapy predicted Motor score. Results of the study underline the importance of considering cognitive, language and motor developments separately when assessing a preterm child's development. Prediction models of developmental performance confirm the influence of some known neonatal risk factors and indicate the need for further research on the role of sociodemographic risk factors.

    Past studies have suggested that conditions experienced by women during pregnancy (e.g. obesity and gestational diabetes mellitus (GDM)) may be associated with having a child with autism spectrum disorder (ASD). Our objective was to compare mothers who had a child diagnosed with ASD to mothers of children with a non-ASD developmental disorder (DD) or without any reported DD (controls). To accomplish the objective we collected medical record data from patients who resided in the Cincinnati Children's Hospital Medical Center's (CCHMC) primary catchment area and linked those data to data from birth certificates (to identify risk factors). Two comparison groups were analyzed; one with DD; and the other, controls without a reported ASD or DD. Descriptive statistics and regression analyses evaluated differences. Differences were greater comparing mothers of ASD to controls than comparing ASD to DD. Maternal obesity and GDM were associated with a statistically significant approximately 1.5-fold increased odds of having a child with an ASD. For mothers with both GDM and obesity, the association was twofold for having a child with ASD compared with controls.

    Objective: A large number of studies have shown the adverse neonatal outcomes of maternal psychological ill health. Given the potentially high prevalence of antenatal anxiety and few studies performed among Chinese people, the authors wanted to investigate the prevalence of antenatal anxiety and associated factors among pregnant women and to provide scientific basis to reduce prenatal anxiety effectively. Methods: A cross-sectional study was carried out at the Changchun Gynecology and Obstetrics Hospital from January 2015 to march 2015, with 467 participants of at least 38 weeks’ gestation enrolled. Antenatal anxiety was measured using the Self-Rating Anxiety Scale (SAS). χ2 test and logistic regression analysis were performed to evaluate the association of related factors of antenatal anxiety. Results: Among the 467 participants, the prevalence of antenatal anxiety was 20.6% (96 of 467). After adjustment for women’s socio-demographic characteristics (e.g., area, age, household income), multivariate logistical regression analysis revealed that antenatal anxiety showed significant relationship with education level lower than middle school (years ≤ 9), expected natural delivery, anemia during pregnancy, pregnancy-induced hypertension syndrome, disharmony in family relationship and life satisfaction. Conclusions: It is important to prevent or reduce antenatal anxiety from occurring by improving the health status of pregnant women and strengthening prenatal-related education and mental intervention.

    Purpose While previous studies have identified a range of potential risk factors for postnatal depression (PND), none have examined a comprehensive set of risk factors at a population-level using data collected prospectively. The aim of this study was to explore the relationship between a range of factors and PND and to construct a model of the predictors of PND. Methods Data came from 5219 women who completed Survey 5 of the Australian Longitudinal Study on Women’s Health in 2009 and reported giving birth to a child. Results Over 15% of women reported experiencing PND with at least one of their children. The strongest positive associations were for postnatal anxiety (OR = 13.79,95%CI = 10.48,18.13) and antenatal depression (OR = 9.23,95%CI = 6.10,13.97). Positive associations were also found for history of depression and PND, low SF-36 Mental Health Index, emotional distress during labour, and breastfeeding for less than six months. Conclusions Results indicate that understanding a woman’s mental health history plays an important role in the detection of those who are most vulnerable to PND. Treatment and management of depression and anxiety earlier in life and during pregnancy may have a positive impact on the incidence of PND. PMID:26785131

    To test the hypothesized anger-mediated relation between maternal depression and escalation of physical discipline, 122 economically disadvantaged mothers were assessed for current and lifetime diagnoses of depression using the Current Depressive Episode, Past Depression, and Dysthymia sections of the Structured Clinical Interview for DSM-IV (SCID) and a measure of current depressive symptoms, the Beck Depression Inventory–Second Edition (BDI-II). Escalation of physical discipline was assessed using a video analog parenting task; maternal anger not specific to discipline was assessed using the Spielberger Trait Anger Expression Inventory. Reports of anger were associated with the diagnosis of depression and depressive symptoms. Bootstrap analyses of indirect effects indicated that the link between depression and escalated discipline was mediated by anger. Parallel analyses based on BDI-II scores identified a marginally significant indirect effect of depression on discipline. Findings suggest that anger and irritability are central to the putative link between depression and harsh discipline. PMID:18174347

    The current study examined the individual and joint effects of self-reported adult attachment style, psychological distress, and parenting stress on maternal caregiving behaviors at 6 and 12 months of child age. We proposed a diathesis-stress model to examine the potential deleterious effects of stress for mothers with insecure adult attachment styles. Data from 137 mothers were gathered by the longitudinal Durham Child Health and Development Study. Mothers provided self-reports using Hazan and Shaver's (1987) Adult Attachment Style measure, the Brief Symptom Inventory, and the Parent Stress Inventory; observations of parenting data were made from 10-minute free play interactions. Consistently avoidant mothers were less sensitive with their infants than consistently secure mothers; however, this effect was limited to avoidant mothers who experienced elevated levels of psychological distress. Results suggest that the association between insecure adult attachment style and insensitive parenting behavior is moderated by concurrent psychosocial stress. Clinical implications for these findings are discussed. PMID:24855326

    Background Global Program to Eliminate Lymphatic Filariasis (GPELF) launched by WHO aims to eliminate the disease by 2020. To achieve the goal annual mass drug administration (MDA) with diethylcarbamazine (DEC) plus albendazole (ABZ) has been introduced in all endemic countries. The current policy however excludes pregnant mothers and children below two years of age from MDA. Since pregnancy and early childhood are critical periods in determining the disease outcome in older age, the present study was undertaken to find out the influence of maternal filarial infection at the time of pregnancy on the susceptibility outcome of children born in a community after implementation of MDA for the first time. Methodology and Principal Findings The participants in this cohort consists of pregnant mothers and their subsequently born children living in eight adjacent villages endemic for filarial infections, in Khurda District, Odisha, India, where MDA has reduced microfilariae (Mf) rate from 12% to 0.34%. Infection status of mother and their children were assessed by detection of Mf as well as circulating filarial antigen (CFA) assay. The present study reveals a high rate of acquiring filarial infection by the children born to infected mother than uninfected mothers even though Mf rate has come down to < 1% after implementation of ten rounds of MDA. Significance To attain the target of eliminating lymphatic filariasis the current MDA programme should give emphasis on covering the women of child bearing age. Our study recommends incorporating supervised MDA to Adolescent Reproductive and Sexual Health Programme (ARSH) to make the adolescent girls free from infection by the time of pregnancy so as to achieve the goal.

    Objective We aimed to test the fetal overnutrition hypothesis by comparing the associations of maternal and paternal adiposity (sum of skinfolds) with adiposity and cardiovascular risk factors in children. Design Children from a prospective birth cohort had anthropometry, fat percentage (bio-impedance), plasma glucose, insulin and lipid concentrations and blood pressure measured at 9·5 years of age. Detailed anthropometric measurements were recorded for mothers (at 30 ± 2 weeks’ gestation) and fathers (5 years following the index pregnancy). Setting Holdsworth Memorial Hospital, Mysore, India. Subjects Children (n 504), born to mothers with normal glucose tolerance during pregnancy. Results Twenty-eight per cent of mothers and 38 % of fathers were overweight/obese (BMI ≥ 25·0 kg/m2), but only 4 % of the children were overweight/obese (WHO age- and sex-specific BMI ≥ 18·2 kg/m2). The children’s adiposity (BMI, sum of skinfolds, fat percentage and waist circumference), fasting insulin concentration and insulin resistance increased with increasing maternal and paternal sum of skinfolds adjusted for the child’s sex, age and socio-economic status. Maternal and paternal effects were similar. The associations with fasting insulin and insulin resistance were attenuated after adjusting for the child’s current adiposity. Conclusions In this population, both maternal and paternal adiposity equally predict adiposity and insulin resistance in the children. This suggests that shared family environment and lifestyle, or genetic/epigenetic factors, influence child adiposity. Our findings do not support the hypothesis that there is an intrauterine overnutrition effect of maternal adiposity in non-diabetic pregnancies, although we cannot rule out such an effect in cases of extreme maternal obesity, which is rare in our population.

    Objective. To identify maternal and early childhood risk factors for obesity and overweight among children at age 5 in the state of Alabama. Methods. We recruited 740 mothers during early pregnancy from University of Alabama Prenatal Clinics in a prospective cohort study and followed them throughout pregnancy. We followed their children from birth until 5 years of age. The main outcome measure was obesity (BMI for age and sex ≥ 95th percentile) at 5 years of age. We used poisson regression with robust variance estimation to compute risk ratio (RR). Results. At the 5th year of followup, 71 (9.6%) of the children were obese and 85 (11.5%) were overweight (BMI ≥ 85th–<95th percentile). In multivariable analysis, maternal prepregnancy overweight (RR: 2.30, 95% CI: 1.29–4.11) and obesity (RR: 2.53, 95% CI: 1.49–4.31), and child's birth weight >85th percentile (RR: 2.04, 95% CI: 1.13–3.68) were associated with childhood obesity. Maternal prepregnancy BMI, birth weight, and maternal smoking were associated with the child being overweight 1–12 cigarettes/day versus 0 cigarettes/day (RR: 1.40, 95% CI: 1.02–1.91). Conclusion. Children of overweight and obese mothers, and children with higher birth weight, are more likely to be obese and overweight at age 5. Maternal smoking 1–12 cigarettes per day is associated with the child being overweight. PMID:23056928

    This longitudinal study examined the influence of parenting behaviors, well-being, and risk factors of low-income adolescent mothers on the cognitive and language abilities of children from infancy to age 3. Participants consisted of 1,240 mother-child dyads enrolled in the Early Head Start Research and Evaluation Project. Data were collected using structured interviews with the mothers and from videotaped mother-child interactions during play activities when children were approximately 14 months old and again at 36 months of age. Positive parenting behaviors exhibited toward the 14-month-old children predicted gains in both cognitive and language abilities more so than did maternal well-being, risk factors within the family setting, and demographic risk factors. Gains in cognitive abilities from infancy to age 3 were predicted by supportive parenting, higher family resources, and lower family conflict when children were infants. Gains in language abilities were predicted by supportive parenting, support for language and learning in the home environment, and higher family resources when children were infants. Finally, path analyses showed that maternal age had an indirect effect on child cognitive and language abilities at age 3 through effects on parenting behaviors. Older mothers were more likely to be supportive during play at age 14 months, which in turn promoted enhanced developmental outcomes at age 3. Implications for intervention and future research are discussed. PMID:21486265

    Objective Lower maternal vitamin D status in pregnancy may be associated with increased offspring cardiovascular risk in later life, but evidence for this is scant. We examined associations of maternal total 25-hydroxyvitamin D (25(OH)D) in pregnancy with offspring cardiovascular risk factors assessed in childhood and adolescence. Design A longitudinal, prospective study. Setting The study was based on data from mother–offspring pairs in the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK prospective population-based birth cohort (N=4109). Outcome measures Offspring cardiovascular risk factors were measured in childhood (mean age 9.9 years) and in adolescence (mean age 15.4 years): blood pressure, lipids, apolipoproteins (at 9.9 years only), glucose and insulin (at 15.4 years only), C reactive protein (CRP), and interleukin 6 (at 9.9 years only) were measured. Results After adjustments for potential confounders (maternal age, education, body mass index (BMI), smoking, physical activity, parity, socioeconomic position, ethnicity, and offspring gestational age at 25(OH)D sampling; gender, age, and BMI at outcome assessment), maternal 25(OH)D was inversely associated with systolic blood pressure (−0.48 mm Hg difference per 50 nmol/L increase in 25(OH)D; 95% CI −0.95 to −0.01), Apo-B (−0.01 mg/dL difference; 95% CI −0.02 to −0.001), and CRP (−6.1% difference; 95% CI −11.5% to −0.3%) at age 9.9 years. These associations were not present for risk factors measured at 15.4 years, with the exception of a weak inverse association with CRP (−5.5% difference; 95% CI −11.4% to 0.8%). There was no strong evidence of associations with offspring triglycerides, glucose or insulin. Conclusions Our findings suggest that fetal exposure to 25(OH)D is unlikely to influence cardiovascular risk factors of individuals later in life. PMID:24125739

    There is increasing evidence that human pregnancy outcome can be significantly compromised by suboptimal maternal nutritional status. Poor diet results in a maternal-fetal environment in which the teratogenicity of other insults such as alcohol might be amplified. As an example, there is evidence that zinc (Zn) can interact with maternal alcohol exposure to influence the risk for fetal alcohol spectrum disorders (FASD). Studies with experimental animals have shown that the teratogenicity of alcohol is increased under conditions of Zn deficiency, while its teratogenicity is lessened when animals are given Zn supplemented diets or Zn injections prior to the alcohol exposure. Alcohol can precipitate an acute phase response resulting in a subsequent increase in maternal liver metallothionein, which can sequester Zn and lead to decreased Zn transfer to the fetus. Importantly, the teratogenicity of acute alcohol exposure is reduced in metallothionein knockout mice, which can have improved Zn transfer to the conceptus relative to wild-type mice. Consistent with the above, Zn status has been reported to be low in alcoholic women at delivery. Preliminary data from two basic science and clinical nutritional studies that are ongoing as part of the international Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD) support the potential role of Zn, among other nutritional factors, relative to risk for FASD. Importantly, the nutrient levels being examined in these studies are relevant to general clinical populations and represent suboptimal levels rather than severe deficiencies. These data suggest that moderate deficiencies in single nutrients can act as permissive factors for FASD, and that adequate nutritional status or intervention through supplementation may provide protection for some of the effects of prenatal alcohol exposure.

    Objectives. We identified individual and contextual factors associated with referral and enrollment in home visiting among at-risk, first-time mothers. Methods. We retrospectively studied referral and enrollment in a regional home visiting program from 2007 to 2009 in Hamilton County, Ohio. Using linked vital statistics and census tract data, we obtained individual and community measures on first-time mothers meeting eligibility criteria for home visiting (low income, unmarried, or age < 18 years). Generalized linear modeling was performed to determine factors associated with relative risk (RR) of (1) referral to home visiting among eligible mothers and (2) enrollment after referral. Results. Of 8187 first-time mothers eligible for home visiting, 2775 were referred and 1543 were enrolled. Among referred women, high school completion (RR = 1.10) and any college (RR = 1.17) compared with no high school completion were associated with increased enrollment, and enrollment was less likely for those living in communities with higher socioeconomic deprivation (RR = 0.71; P < .05). Conclusions. Barriers to enrollment in home visiting persisted at multiple ecological levels. Ongoing evaluation of enrollment in at-risk populations is critical as home visiting programs are implemented and expanded. PMID:24354835

    2006-09-01

    Iron deficiency is the most common micronutrient deficiency during pregnancy, and maternal anemia has been associated with poor pregnancy outcomes. However, it is still not clear how directly maternal iron status is linked to the infant's iron status postpartum. We investigated the impact of maternal iron deficiency on the hematological status of infant rhesus monkeys. Two groups of females, 8 iron deficient and 8 iron sufficient were assessed through pregnancy and for 6 mo postpartum. At conception, 4 females in each group were provided an iron-enriched diet. Iron status of the infant at birth reflected the preconception status of the mother, regardless of diet. Serum ferritin (Ft) concentrations were significantly higher in infants born to iron-sufficient mothers and were correlated with maternal transferrin saturation at entrance to the study (r = 0.52, P < 0.04). Infant iron status continued to reflect prenatal conditions through 6 mo of age. Our study confirmed the importance of iron sufficiency in gravid female monkeys for ensuring their infants' normal hematological development postpartum. A dietary intervention during pregnancy with only a moderate addition of iron was not sufficient to prevent the offspring from developing iron deficiency. These findings stress the importance of improving iron nutriture prior to conception. PMID:16920852

    This study looked to identify determinants of exposure to dioxin in breast milk from breast-feeding women in a hot spot of dioxin exposure in Vietnam. Breast milk was collected from 140 mothers 1 month after delivery. The risk factors investigated included length of residency, drinking of well water and the frequency of animal food consumption. Cluster analysis was performed to identify dietary patterns of fish and meat portions, fish variety and egg variety. Residency, age and parity were clearly associated with increased dioxin levels. Drinking well water and the consumption of marine crab and shrimps were related to higher levels of furans in breast milk. The consumption of quail eggs also appeared to be associated with increased levels of some dioxin isomers in this area. Some mothers who ate no or less meat than fish and mothers who consumed more freshwater fish than marine fish had lower levels of dioxins in their breast milk. However, the type of water and the eating habits of mothers contributed only partly to the increased dioxin levels in their breast milk; the length of residency was the most important risk factor associated with increased dioxin body burdens of mothers.

    Child health is fundamental to well-being and achievement throughout the life course. Prior research has demonstrated strong associations between familial socioeconomic resources and children’s health outcomes, with especially poor health outcomes among disadvantaged youth who experience a concentration of risks, yet little is known about the influence of maternal health as a dimension of risk for children. This research used nationally representative U.S. data from the National Health Interview Surveys in 2007 and 2008 (N = 7,361) to evaluate the joint implications of maternal health and socioeconomic disadvantage for youth. Analyses revealed that maternal health problems were present in a substantial minority of families, clustered meaningfully with other risk factors, and had serious implications for children’s health. These findings support the development of health policies and interventions aimed at families. PMID:23794751

    Women with a history of reproductive loss may be at an increased risk of having an unfavourable outcome in subsequent pregnancies. Using data from a matched case-control study based on the record of the Epidemiological Surveillance System of Neural Tube Defects, we evaluated the association between history of maternal reproductive loss and the risk of anencephaly in three Mexican states. Mothers of 157 cases of anencephaly and 151 controls born during the period March 2000 to February 2001, were interviewed about their reproductive history and other additional factors, including socio-economic characteristics, prenatal care, use of tobacco and alcohol, presence of chronic diseases, acute illnesses and fever during the periconceptional period, and consumption of multivitamins and medicines during this period; mothers who reported no prior pregnancies were excluded from the analysis; 58 matched case-control pairs were used for the analysis. After adjusting for potential confounders, women with a history of miscarriage in previous pregnancies had 4.58 times more risk of having a child with anencephaly, than those who did not have this history; OR = 4.58, [95% CI 1.22, 17.23]. Our results suggest that a history of previous miscarriages is a risk indicator for anencephaly in future gestations. This does not necessarily mean that the miscarriage itself is the cause, but that common mechanisms could be involved in the aetiology of both events. Thus, women who have had histories of reproductive losses, especially miscarriages, should be a priority group for the primary and secondary prevention of neural tube defects. PMID:16629695

    Maternal smoking during pregnancy is one proposed risk factor for gastroschisis, but reported associations have been modest, suggesting that differences in genetic susceptibility might play a role. We included 108 non-Hispanic white and 62 Hispanic families who had infants with gastroschisis, and 1,147 non-Hispanic white and 337 Hispanic families who had liveborn infants with no major structural birth defects (controls) in these analyses. DNA was extracted from buccal cells collected from infants and mothers, and information on periconceptional smoking history was obtained from maternal interviews, as part of the National Birth Defects Prevention Study. We analyzed five polymorphisms in three genes that code for enzymes involved in metabolism of some cigarette smoke constituents (CYP1A1, CYP1A2, and NAT2). Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) independently for maternal smoking and maternal and infant gene variants, and to assess joint associations of maternal smoking and maternal or infant gene variants with gastroschisis. In analyses adjusted for maternal age at delivery and stratified by maternal race-ethnicity, we identified three suggestive associations among 30 potential associations with sufficient numbers to calculate ORs: CYP1A1*2A for non-Hispanic white mothers who smoked periconceptionally (aOR = 0.38, 95% CI 0.15-0.98), and NAT2*6 for Hispanic non-smoking mothers (aOR = 2.17, 95% CI 1.12-4.19) and their infants (aOR = 2.11, 95% CI 1.00-4.48). This analysis does not support the occurrence of effect modification between periconceptional maternal smoking and most of the xenobiotic metabolizing enzyme gene variants assessed. PMID:24668907

    While much has been learned about depression in mothers as a risk for the development of psychopathology in offspring, many questions about how the risk is transmitted remain unanswered. Moreover, maternal depression is too often considered to be a unitary construct, ignoring the likely diversity among mothers with depression, which could play essential roles in understanding not only mechanisms of risk but also moderators of risk, i.e. for whom the association between maternal depression and adverse offspring outcomes may be stronger. Sellers et al. address both mechanisms and moderators, thereby contributing to the understanding of risk to offspring of depressed mothers in these two important ways. There is much to learn from this work, on many levels and for different audiences, including both researchers and practitioners. A key take-home message of this study for all readers is that understanding the role of maternal depression in associations with child psychopathology requires a nuanced view of the nature of risk to children from depression in mothers. The often co-occurring disorders and highly correlated additional aspects of the context in which depression occurs play important roles in the development of psychopathology in the offspring of depressed mothers.

    Purpose Intimate partner violence is a worldwide public health concern predominantly affecting women of reproductive age. The purpose of this study was to evaluate the effect of exposure to intimate partner violence before, during or after pregnancy on postpartum depression in a nationally representative sample of Canadian women. Methods A cross-sectional analysis was performed using data from the Maternity Experience Survey conducted by Statistics Canada in 2006. A population-based sample of 8,542 women 15 years and older who delivered singleton live births was selected from all Canadian provinces and territories; of those, 6,421 completed a computer-assisted telephone interview. Recent experiences with and threats of physical or sexual violence by an intimate partner were examined in relation to postpartum depression assessed through the Edinburgh Postpartum Depression Scale. Results The prevalence of postpartum depression was 7.5% (95% CI: 6.8, 8.2). Controlling for confounders, odds of postpartum depression were significantly higher among women who reported partner violence in the past two years as opposed to those who did not (adjusted OR=1.61; 95% CI: 1.06, 2.45). Conclusions Intimate partner violence is positively associated with postpartum depression among Canadian women. Implications for healthcare practice are discussed. PMID:20609336

    Background Disruption in the parent-child relationship is a commonly hypothesised risk factor through which maternal depression may increase risk for offspring psychopathology. However, maternal depression is commonly accompanied by other psychopathology, including antisocial behaviour. Few studies have examined the role of co-occurring psychopathology in depressed mothers. Using a longitudinal study of offspring of mothers with recurrent depression, we aimed to test whether maternal warmth/hostility mediated links between maternal depression severity on child outcomes, and how far direct and indirect pathways were robust to controls for co-occurring maternal antisocial behaviour. Methods Mothers with a history of recurrent major depressive disorder and their adolescent offspring (9–17 years at baseline) were assessed three times between 2007 and 2010. Mothers completed questionnaires assessing their own depression severity and antisocial behaviour at Time 1 (T1). The parent-child relationship was assessed using parent-rated questionnaire and interviewer-rated five-minute speech sample at Time 2 (T2). Offspring symptoms of depression and disruptive behaviours were assessed using the Child and Adolescent Psychiatric Assessment at Time 3 (T3). Results Maternal hostility and warmth respectively mediated the association between maternal depression severity and risk for offspring psychopathology. However, the effects were attenuated when maternal antisocial behaviour was included in the analysis. In tests of the full theoretical model, maternal antisocial behaviour predicted both maternal hostility and low warmth, maternal hostility predicted offspring disruptive behaviour disorder symptoms but not depression, and maternal warmth was not associated with either child outcome. Conclusions Parenting interventions aimed at reducing hostility may be beneficial for preventing or reducing adolescent disruptive behaviours in offspring of depressed mothers, especially when

    The role of reproductive factors, such as parental age, in the pathogenesis of childhood leukemias is being intensively examined; the results of individual studies are controversial. This meta-analysis aims to quantitatively synthesize the published data on the association between parental age and risk of two major distinct childhood leukemia types in the offspring. Eligible studies were identified and pooled relative risk (RR) estimates were calculated using random-effects models, separately for childhood acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). Subgroup analyses were performed by study design, geographical region, adjustment factors; sensitivity analyses and meta-regression analyses were also undertaken. 77 studies (69 case-control and eight cohort) were deemed eligible. Older maternal and paternal age were associated with increased risk for childhood ALL (pooled RR = 1.05, 95 % CI 1.01-1.10; pooled RR = 1.04, 95 % CI 1.00-1.08, per 5 year increments, respectively). The association between maternal age and risk of childhood AML showed a U-shaped pattern, with symmetrically associated increased risk in the oldest (pooled RR = 1.23, 95 % CI 1.06-1.43) and the youngest (pooled RR = 1.23, 95 % CI 1.07-1.40) extremes. Lastly, only younger fathers were at increased risk of having a child with AML (pooled RR = 1.28, 95 % CI 1.04-1.59). In conclusion, maternal and paternal age represents a meaningful risk factor for childhood leukemia, albeit of different effect size by leukemia subtype. Genetic and socio-economic factors may underlie the observed associations. Well-adjusted studies, scheduled by large consortia, are anticipated to satisfactorily address methodological issues, whereas the potential underlying genetic mechanisms should be elucidated by basic research studies.

    2012-01-01

    Background Advanced maternal age (AMA) is associated with several adverse pregnancy outcomes, hence these pregnancies are considered to be “high risk.” A review of the empirical literature suggests that it is not clear how women of AMA evaluate their pregnancy risk. This study aimed to address this gap by exploring the risk perception of pregnant women of AMA. Methods A qualitative descriptive study was undertaken to obtain a rich and detailed source of explanatory data regarding perceived pregnancy risk of 15 women of AMA. The sample was recruited from a variety of settings in Winnipeg, Canada. In-depth interviews were conducted with nulliparous women aged 35 years or older, in their third trimester, and with singleton pregnancies. Interviews were recorded and transcribed verbatim, and content analysis was used to identify themes and categories. Results Four main themes emerged: definition of pregnancy risk, factors influencing risk perception, risk alleviation strategies, and risk communication with health professionals. Conclusions Several factors may influence women's perception of pregnancy risk including medical risk, psychological elements, characteristics of the risk, stage of pregnancy, and health care provider’s opinion. Understanding these influential factors may help health professionals who care for pregnant women of AMA to gain insight into their perspectives on pregnancy risk and improve the effectiveness of risk communication strategies with this group.

    Daughters of HIV-positive women are often exposed to the same factors that placed their mothers at risk. This cross-sectional study (N = 176 dyads) examined HIV status, parent-teen sexual risk communication (PTSRC), and daughters’ abstinence and condom use beliefs and intentions. Maternal HIV status was not associated with PTSRC. Path analyses show that maternal depression was associated with PTSRC behavioral and normative beliefs; relationship satisfaction was associated with PTSRC normative and control beliefs. Control beliefs were solely predictive of maternal PTSRC intention. PTSRC was associated with adolescent behavioral and normative beliefs. Abstinence beliefs were associated with abstinence intentions; condom beliefs were associated with condom use intentions. Relationship satisfaction was associated with adolescent control beliefs about both abstinence and condom use. There is a need for interventions that help HIV-positive mothers recognize their daughter’s HIV risk and provide them with relationship building and parent process skills to help reduce these risks.

    A failure of integrative processes within the brain, mediated via altered GABAergic inhibition, may underlie several features of schizophrenia. The present study examined, therefore, whether maternal immune activation (MIA), a risk factor for schizophrenia, altered inhibitory markers in the hippocampus and medial prefrontal cortex (mPFC), while also altering electroencephalogram (EEG) coherence between these regions. Pregnant rats were treated with saline or polyinosinic:polycytidylic acid mid-gestation. EEG depth recordings were made from the dorsal and ventral hippocampus and mPFC of male adult offspring. Glutamic decarboxylase (GAD67) levels were separately assayed in these regions using western blot. GAD67 expression was also assessed within parvalbumin-positive cells in the dorsal and ventral hippocampus using immunofluorescence alongside stereological analysis of parvalbumin-positive cell numbers. EEG coherence was reduced between the dorsal hippocampus and mPFC, but not the ventral hippocampus and mPFC, in MIA animals. Western blot and immunofluorescence analyses revealed that GAD67 expression within parvalbumin-positive cells was also reduced in the dorsal hippocampus relative to ventral hippocampus in MIA animals when compared with controls. This reduction was observed in the absence of parvalbumin-positive neuronal loss. Overall, MIA produced a selective reduction in EEG coherence between the dorsal hippocampus and mPFC that was paralleled by a similarly specific reduction in GAD67 within parvalbumin-positive cells of the dorsal hippocampus. These results suggest a link between altered inhibitory mechanisms and synchrony and, therefore point to potential mechanisms via which a disruption in neurodevelopmental processes might lead to pathophysiology associated with schizophrenia.

    The transition from late childhood through middle adolescence represents a critical developmental period during which there is a rapid increase in the initiation and escalation of alcohol use. Alcohol use is part of a constellation of risk taking behaviors that increase during this developmental transition, which can be explained by environmental and genetic factors. Social learning theory (SLT) implicates observations of parental drinking in the development of alcohol use in youth. Parental risk taking more broadly has not previously been examined as a factor predictive of alcohol use escalation in youth across adolescence. The current study examined the relative contributions of maternal risk taking on the Balloon Analogue Risk Task (BART) and maternal alcohol use in the prediction of alcohol escalation among youth over three years. Participants were a sample of 245 youth (55.0% male, 49.6% Caucasian) who participated annually between grades 8 and 10, drawn from a larger study of adolescent risk taking. Within our sample, maternal risk taking, as measured by the BART, predicted increases in alcohol use. Interestingly, maternal alcohol use and other youth factors were not predictive of escalations in youth alcohol use. Our findings suggest the importance of considering maternal riskiness more broadly, rather than solely focusing on maternal alcohol use when attempting to understand youth alcohol use across adolescence. These findings emphasize the relevance of maternal risk taking as measured by a behavioral task and suggest a general level of riskiness displayed by mothers might encourage youth to behave in a riskier manner themselves.

    The present study sought to further specify conceptual models of youth positive affect (PA) by examining mothers’ observed PA as a mediator of the relation between family risk (based on maternal reports of demographic factors) and children’s PA in a sample of 82 mothers (M = 31.25 years, SD = 6.16) and their preschool-aged children (M = 3.51 years, SD = .49, 63.00% boys). Results yielded a significant, negative correlation between family risk and child PA. Mediation analyses indicated that family risk was related to child PA through its effects on maternal PA, even after controlling for maternal depression symptoms. Findings suggest that family risk and maternal PA are important factors to consider in understanding preschoolers’ PA development. Identifying children at risk for developing PA difficulties can aid in the implementation of prevention and intervention strategies for promoting young children’s PA specifically, and their psychosocial functioning more broadly.

    Maternal insulin-like growth factors (IGFs) play a pivotal role in modulating fetal growth via their actions on both the mother and the placenta. Circulating IGFs influence maternal tissue growth and metabolism, thereby regulating nutrient availability for the growth of the conceptus. Maternal IGFs also regulate placental morphogenesis, substrate transport and hormone secretion, all of which influence fetal growth either via indirect effects on maternal substrate availability, or through direct effects on the placenta and its capacity to supply nutrients to the fetus. The extent to which IGFs influence the mother and/or placenta are dependent on the species and maternal factors, including age and nutrition. As altered fetal growth is associated with increased perinatal morbidity and mortality and a greater risk of developing degenerative diseases in adult life, understanding the role of maternal IGFs during pregnancy is essential in order to identify mechanisms underlying altered fetal growth and offspring programming.

    The prognosis of children with congenital heart defects(CHDs) continues to improve with advancing surgical techniques; however, lack of information about modifiable risk factors for malformations in cardiovascular development impeded the prevention of CHDs. We investigated an association between maternal lifestyle factors and the risk of CHDs, because epidemiological studies have reported conflicting results regarding maternal lifestyle factors and the risk of CHDs recently. A review published on 2007 provided a summary of maternal exposures associated with an increased risk of CHDs. As part of noninherited risk factors, we conducted a brief overview of studies on the evidence linking common maternal lifestyle factors, specifically smoking, alcohol, illicit drugs, caffeine, body mass index and psychological factors to the development of CHDs in offspring. Women who smoke and have an excessive body mass index(BMI) during pregnancy are suspected to be associated with CHDs in offspring. Our findings could cause public health policy makers to pay more attention to women at risk and could be used in the development of population-based prevention strategies to reduce the incidence and burden of CHDs. However, more prospective studies are needed to investigate the association between maternal lifestyle factors and CHDs. PMID:25385357

    Objective To investigate whether patients with a history of preeclampsia have an increased risk of long-term ophthalmic complications. Study Design A population-based study comparing the incidence of long-term maternal ophthalmic complications in a cohort of women with and without a history of preeclampsia. Results During the study period, a total of 103,183 deliveries met the inclusion criteria; 8.1% (n = 8,324) occurred in patients with a diagnosis of preeclampsia during at least one of their pregnancies. Patients with preeclampsia had a significantly higher incidence of long-term ophthalmic morbidity such as diabetic retinopathy and retinal detachment. In addition, a positive linear correlation was found between the severity of preeclampsia and the prevalence of future ophthalmic morbidities (0.3 vs. 0.5 vs. 2.2%, respectively). Kaplan-Meier survival curve indicated that women with preeclampsia had higher rates of total ophthalmic morbidity (0.2 vs. 0.4%, for no preeclampsia and with preeclampsia, respectively; odds ratio = 2.06, 95% confidence interval: 1.42-2.99; p < 0.001). In a Cox proportional hazards model, adjusted for confounders, a history of preeclampsia remained independently associated with ophthalmic complications. Conclusion Preeclampsia is an independent risk factor for long-term maternal ophthalmic morbidity, specifically diabetic retinopathy and retinal detachment. This risk is more substantial depending on the severity of the disease. PMID:26871904

    Objectives To examine the effect of maternal HIV infection, as well as other individual, family, and contextual factors on the mental health of inner-city, ethnic minority early adolescents. Methods Participants included 220 HIV-negative early adolescents (10–14 years) and their mothers, half of whom were HIV-infected. Individual interviews were conducted regarding youth depression, anxiety, externalizing and internalizing behaviour problems, as well as a range of correlates of youth mental health guided by a modified version of Social Action Theory, a theoretical model of behavioral health. Results Although the HIV status of mothers alone did not predict youth mental health, youth knowledge of mother's HIV infection and mother's overall health were associated with worse youth mental health outcomes, as were contextual, self-regulation, and family interaction factors from our theoretical model. Conclusions There is a need for family-based mental health interventions for this population, particularly focusing on parent–child relationships, disclosure, and youth self-esteem. PMID:18250092

    An estimated 200 million children worldwide fail to meet their development potential due to poverty, poor health and unstimulating environments. Missing developmental milestones has lasting effects on adult human capital. Africa has a large burden of risk factors for poor child development. The objective of this paper is to identify scope for improvement at the country level in three domains--nutrition, environment, and mother-child interactions. We used nationally representative data from large-scale surveys, data repositories and country reports from 2000 to 2014. Overall, there was heterogeneity in performance across domains, suggesting that each country faces distinct challenges in addressing risk factors for poor child development. Data were lacking for many indicators, especially in the mother-child interaction domain. There is a clear need to improve routine collection of high-quality, country-level indicators relevant to child development to assess risk and track progress. PMID:26358240

    Child mortality (the mortality of children less than five years old) declined considerably in the developing world in the 1990s, but infant mortality declined less. The reductions in neonatal mortality were not impressive and, as a consequence, there is an increasing percentage of infant deaths in the neonatal period. Any further reduction in child mortality, therefore, requires an understanding of the determinants of neonatal mortality. 209,628 birth and 2581 neonatal death records for the 1998 birth cohort from the city of São Paulo, Brazil, were probabilistically matched. Data were from SINASC and SIM, Information Systems on Live Births and Deaths of Brazil. Logistic regression was used to find the association between neonatal mortality and the following risk factors: birth weight, gestational age, Apgar scores at 1 and 5 minutes, delivery mode, plurality, sex, maternal education, maternal age, number of prior losses, prenatal care, race, parity and community development. Infants of older mothers were less likely to die in the neonatal period. Caesarean delivery was not found to be associated with neonatal mortality. Low birth weight, pre-term birth and low Apgar scores were associated with neonatal death. Having a mother who lives in the highest developed community decreased the odds of neonatal death, suggesting that factors not measured in this study are behind such association. This result may also indicate that other factors over and above biological and more proximate factors could affect neonatal death. PMID:15768774

    2011-11-01

    Obesity is a public health concern worldwide, arising from multifaceted and complex causes that relate to individual choice and lifestyle, and the influences of wider society. In addition to a long-standing focus on both childhood and adult obesity, there has been more recent concern relating to maternal obesity. This review explores the published evidence relating to maternal obesity incidence and associated inequalities, the impact of obesity on maternity services, and associated guidelines. Epidemiological data comprising three national maternal obesity datasets within the UK have identified a significant increase in maternal obesity in recent years, and reflect broad socio-demographic inequalities particularly deprivation, ethnicity and unemployment. Obese pregnancies present increased risk of complications that require more resource intensive antenatal and perinatal care, such as caesarean deliveries, gestational diabetes, haemorrhage, infections and congenital anomalies. Healthcare professionals also face difficulties when managing the care of women in pregnancy as obesity is an emotive and stigmatising topic. There is a lack of good-quality evidence for effective interventions to tackle maternal obesity. Recently published national guidelines for the clinical management and weight management of maternal obesity offer advice for professionals, but acknowledge the limitations of the evidence base. The consequence of these difficulties is an absence of support services available for women. Further evaluative research is thus required to assess the effectiveness of interventions with women before, during and after pregnancy. Qualitative work with women will also be needed to help inform the development of more sensitive risk communication and women-centred services. PMID:21854697

Methods: This observational cross sectional study was conducted at intensive care unit of Liaquat University of Medical and Health sciences Jamshoro from 1-January-2011 to 31-December-2012. In this study all the delivered or undelivered women who needed intensive care unit (ICU) admission due to management related life threatening complication referred from periphery or within this hospital were included, while those women who had pregnancy complicated by medical conditions were excluded. These women were registered on the predesigned proforma containing variables like Demographic characteristics, various iatrogenic risk factors, complications and management out comes. The data was collected and analyzed on SPSS version 20. Results: During these study period 51 women needed ICU care for different complications due to adverse effects of medical treatments. Majority of these women were between 20-40 years of age 41(80.39%), multiparous 29(56.86%), unbooked 38(74.50%), referred from periphery 39(76.47%), common iatrogenic factors were misuse of oxytocin 16(31.37%), fluid overload/cardiac failure 8(15.68%), blood reaction 7(13.72%), anesthesia related problems were delayed recovery 3(5.88%), cardiac arrest 2(3.92%), spinal shock 2(3.92%), surgical problems were bladder injury 5(9.8%), post operative internal haemorrhage 3(5.88%), 37(72.54%) women recovered and 14(27.45%) expired.

    Introduction: Congenital heart disease (CHD) is associated with multiple risk factors, consanguinity may be one such significant factor. The role of consanguinity in the etiology of CHD is supported by inbreeding studies, which demonstrate an autosomal recessive pattern of inheritance of some congenital heart defects. This study was done to find out the risk factors for CHD. Methods: A case-control study was done on pediatric patients at a tertiary care hospital, Aga Khan University Hospital, located in Karachi, Pakistan. A total of 500 patients, 250 cases and 250 controls were included in the study. Results: Amongst the 250 cases (i.e. those diagnosed with CHD), 122 patients (48.8%) were born of consanguineous marriages while in the controls (i.e. non-CHD) only 72 patients (28.9%) showed a consanguinity amongst parents. On multivariate analysis, consanguinity emerged as an independent risk factor for CHD; adjusted odds ratio 2.59 (95% C. I. 1.73 - 3.87). Other risk factors included low birth weight, maternal co-morbidities, family history of CHD and first born child. On the other hand, medications used by the mother during the index pregnancy, maternal age and gender of the child did not significantly increase the risk of developing CHD. Conclusions: Analyses of our results show that parental consanguinity, family history of CHD, maternal co-morbidities, first born child and low birth weight are independent risk factors for CHD.

    This paper examines the impact of marital status on maternal mortality in the period before and the period after German reunification in the area covered by the former East Germany. Maternal mortality ratio prior to the reunification was stable and declined after reunification. This can be attributed to the adoption of a lenient reporting system from West Germany. Unmarried status, on the other hand, became a significant risk factor for maternal mortality after reunification due to changes in support program for pregnant women and mothers, and socioeconomic factors. Elimination of support measures like incentives for check-ups, follow-ups, and guaranteed jobs for single mothers in eastern Germany before the reunification explains the increased maternal mortality rate. In West Germany, unmarried women were associated with low socioeconomic status. Conditions of higher maternal risk and lower socioeconomic status among unmarried mothers from East Germany is now similar to the situation of unmarried mothers in West Germany. PMID:10531100

    Children of incarcerated mothers are at increased risk for social and emotional difficulties, yet few studies have investigated potential mechanisms of risk within this population. This research simultaneously examined the association of children’s experience of incarceration-specific risk factors (e.g., witness mother’s arrest) and environmental risks (e.g., low educational attainment) to children’s psychological maladaptation using a multi-informant design and a latent variable analytic approach. Participants were 117 currently incarcerated mothers (64.1% African American), their 151 children (53.6% boys, M age =9.8 years, range =6–12 years, 61.7% African American), and the 118 caregivers (74.8% female, 61.9% grandparents, 62.2% African American) of the children. Mothers, children, and caregivers each provided accounts of children’s experiences related to maternal incarceration and children’s internalizing and externalizing behavior problems. Mothers and caregivers each supplied information about 10 environmental risk factors. Findings from structural equation modeling indicate that children’s incarceration-specific risk experiences predict internalizing and externalizing behavior problems whereas the influence of environmental risks was negligible. Follow-up analyses examining the contribution of specific risks indicate that significant predictors differ by reporter and separate into effects of family incarceration history and direct experiences of maternal incarceration. Incarceration-specific experiences place children at higher risk for maladjustment than exposure to general environmental risk factors. These findings indicate the need to critically examine children’s exposure to experiences related to maternal incarceration and family incarceration history to help to clarify the multifaceted stressor of maternal incarceration.

    Two research areas that could benefit from a greater focus on the role of the reward pathway are maternal depression and maternal addiction. Both depression and addiction in mothers are mediated by deficiencies in the reward pathway and represent substantial risks to the health of offspring and future generations. This targeted review discusses maternal reward deficits in depressed and addicted mothers, neural, genetic, and epigenetic mechanisms, and the transgenerational transmission of these deficits from mother to offspring. Postpartum depression and drug use disorders may entail alterations in the reward pathway, particularly in striatal and prefrontal areas, which may affect maternal attachment to offspring and heighten the risk of transgenerational effects on the oxytocin and dopamine systems. Alterations may involve neural circuitry changes, genetic factors that impact monoaminergic neurotransmission, as well as growth factors such as BDNF and stress-associated signaling in the brain. Improved maternal reward-based preventative measures and treatments may be specifically effective for mothers and their offspring suffering from depression and/or addiction.

    Background. Systematic reviews (SR) and meta-analyses (MA) that previously explored the relationship between prenatal maternal anxiety (PMA) and preterm birth (PTB) have not been comprehensive in study inclusion, failing to account for effects of heterogeneity and disagree in their conclusions. Objectives. This SRMA provides a summary of the published evidence of the relationship between PMA and PTB while examining methodological and statistical sources of heterogeneity. Methods. Published studies from MEDLINE, CINAHL, PsycINFO, and EMBASE, until June 2015, were extracted and reviewed. Results. Of the 37 eligible studies, 31 were used in this MA; six more were subsequently excluded due to statistical issues, substantially reducing the heterogeneity. The odds ratio for PMA was 1.70 (95% CI 1.33, 2.18) for PTB and 1.67 (95% CI 1.35, 2.07) for spontaneous PTB comparing higher levels of anxiety to lower levels. Conclusions. Consistent findings indicate a significant association between PMA and PTB. Due to the statistical problem of including collinear variables in a single regression model, it is hard to distinguish the effect of the various types of psychosocial distress on PTB. However, a prenatal program aimed at addressing mental health issues could be designed and evaluated using a randomised controlled trial to assess the causal nature of different aspects of mental health on PTB.

  13. Factors in risk perception

    Risk perception is a phenomenon in search of an explanation. Several approaches are discussed in this paper. Technical risk estimates are sometimes a potent factor in accounting for perceived risk, but in many important applications it is not. Heuristics and biases, mainly availability, account for only a minor portion of risk perception, and media contents have not been clearly implicated in risk perception. The psychometric model is probably the leading contender in the field, but its explanatory value is only around 20% of the variance of raw data. Adding a factor of "unnatural risk" considerably improves the psychometric model. Cultural Theory, on the other hand, has not been able to explain more than 5-10% of the variance of perceived risk, and other value scales have similarly failed. A model is proposed in which attitude, risk sensitivity, and specific fear are used as explanatory variables; this model seems to explain well over 30-40% of the variance and is thus more promising than previous approaches. The model offers a different type of psychological explanation of risk perception, and it has many implications, e.g., a different approach to the relationship between attitude and perceived risk, as compared with the usual cognitive analysis of attitude.

    Background The etiology of non-genetic intellectual disability (ID) is not fully known, and we aimed to identify the prenatal, perinatal and neonatal risk factors for ID. Method PubMed and Embase databases were searched for studies that examined the association between pre-, peri- and neonatal factors and ID risk (keywords “intellectual disability” or “mental retardation” or “ID” or “MR” in combination with “prenatal” or “pregnancy” or “obstetric” or “perinatal” or “neonatal”. The last search was updated on September 15, 2015. Summary effect estimates (pooled odds ratios) were calculated for each risk factor using random effects models, with tests for heterogeneity and publication bias. Results Seventeen studies with 55,344 patients and 5,723,749 control individuals were eligible for inclusion in our analysis, and 16 potential risk factors were analyzed. Ten prenatal factors (advanced maternal age, maternal black race, low maternal education, third or more parity, maternal alcohol use, maternal tobacco use, maternal diabetes, maternal hypertension, maternal epilepsy and maternal asthma), one perinatal factor (preterm birth) and two neonatal factors (male sex and low birth weight) were significantly associated with increased risk of ID. Conclusion This systemic review and meta-analysis provides a comprehensive evidence-based assessment of the risk factors for ID. Future studies are encouraged to focus on perinatal and neonatal risk factors and the combined effects of multiple factors. PMID:27110944

    Failure to diagnose abdominal pregnancies can have disastrous morbidity/mortality consequences for mother and fetus. To make the diagnosis of abdominal pregnancy requires that the physician have a high index of suspicion and that he or she have a good understanding of the risk factors of abdominal pregnancy. This article presents data suggesting that maternal cocaine use is a risk factor for abdominal pregnancy, reviews the literature on the maternal/fetal effects of maternal cocaine use and the risk factors of abdominal pregnancy, and analyzes 55 cases of abdominal pregnancy. Maternal cocaine use correlated with a 20% rate of increase in the incidence of abdominal pregnancy compared with the 70% rate of decrease in the "before cocaine" time period. Recommendations are offered for management. PMID:9617068

    Prenatal and postnatal period presents the highest prevalence of mental disorders in women’s lives and depression is the most frequent one, affecting approximately one in every five mothers. The aggravating factor here is that during this period psychiatric symptoms affect not only women’s health and well-being but may also interfere in the infant’s intra and extra-uterine development. Although the causes of the relationship between maternal mental disorders and possible risks to a child’s health and development remain unknown, it is suspected that these risks may be related to the use of psychotropic drugs during pregnancy, to substance abuse and the mother’s lifestyle. Moreover, after delivery, maternal mental disorders may also impair the ties of affection (bonding) with the newborn and the maternal capacity of caring in the post-partum period thus increasing the risk for infant infection and malnutrition, impaired child growth that is expressed in low weight and height for age, and even behavioral problems and vulnerability to presenting mental disorders in adulthood. Generally speaking, research on this theme can be divided into the type of mental disorder analyzed: studies that research minor mental disorders during pregnancy such as depression and anxiety find an association between these maternal disorders and obstetric complications such as prematurity and low birth weight, whereas studies that evaluate severe maternal mental disorders such as schizophrenia and bipolar disorder have found not only an association with general obstetric complications as well as with congenital malformations and perinatal mortality. Therefore, the success of infant growth care programs also depends on the mother’s mental well being. Such findings have led to the need for new public policies in the field of maternal-infant care geared toward the population of mothers. However, more research is necessary so as to confirm the association between all factors with

    2015-01-01

    Children with fragile X syndrome (FXS) demonstrate high rates of anxiety disorders, with 65–83% meeting diagnostic criteria. The severity of anxiety symptoms in FXS has been shown to be partially predicted by elevated negative affect across early childhood (Tonnsen, Malone, et al., 2013). This association suggests that biologically-driven vulnerability emerges early in development, as is reported in non-clinical populations. However, anxiety emergence is likely moderated by multifaceted genetic, biological and environmental risk and protective factors. Mothers with the FMR1 premutation have been shown to exhibit elevated parenting stress and internalizing symptoms, which have each been associated with child behavior problems (Bailey, et al., 2008). Despite these findings, it is unclear whether maternal factors directly relate to anxiety vulnerability in high-risk children with FXS, a question essential to informing targeted, family-sensitive treatment. The present study examines how maternal protective and risk factors relate to child inhibition reflected in (1) child anxiety symptoms, (2) child trajectories of negative affect, and (3) the association between child anxiety and negative affect. Primary predictors include maternal parenting stress, indicators of mental health risk (anxiety and depressive symptoms), and maternal optimism. We also examine genetic correlates in mothers (CGG repeats, activation ratio, mRNA). Our findings suggest that behavioral inhibition in young children with FXS is associated with higher parenting stress and lower optimism, and higher parenting stress is associated with lower maternal X-activation ratio. These findings underscore the need for family-sensitive treatment strategies for anxiety disorders in children with FXS. PMID:24832235

    The risk of progression from exposure to the tuberculosis bacilli to the development of active disease is a two-stage process governed by both exogenous and endogenous risk factors. Exogenous factors play a key role in accentuating the progression from exposure to infection among which the bacillary load in the sputum and the proximity of an individual to an infectious TB case are key factors. Similarly endogenous factors lead in progression from infection to active TB disease. Along with well-established risk factors (such as human immunodeficiency virus (HIV), malnutrition, and young age), emerging variables such as diabetes, indoor air pollution, alcohol, use of immunosuppressive drugs, and tobacco smoke play a significant role at both the individual and population level. Socioeconomic and behavioral factors are also shown to increase the susceptibility to infection. Specific groups such as health care workers and indigenous population are also at an increased risk of TB infection and disease. This paper summarizes these factors along with health system issues such as the effects of delay in diagnosis of TB in the transmission of the bacilli. PMID:23476764

    A review of maternal deaths at Rajendra Hospital, Punjab, from January 1978 to December 1991 yielded important data for the planning of maternal health services in this area of India, During the 14 year study period, there were 33,160 births and 339 deaths, for a maternal mortality rate of 1002/100,000 live births. Women who had received no prenatal care accounted for 47.4% of deliveries but 92.8% of maternal deaths. In addition, a disproportionate number of deaths involved rural women (74.6%) and poor women (76.4%). 57.8% of maternal deaths involved women 21-30 years of age; 37.1% occurred among primigravidas. Direct obstetrical causes were considered the etiologic factor in 83.1% of these deaths. Primary among these causes were sepsis (37.1%), obstetric hemorrhage (26.2%), hypertensive disorders of pregnancy (21.4%), and obstructed labor (15.3%). 30.6% of deaths occurred during pregnancy, 50.3% during labor, and 19.1% in the postpartum period. Indirect obstetrical causes, notably severe anemia and anesthesia complications, were implicated in 15.3% of the maternal deaths. Critical analysis of the maternal deaths in this series suggested that 89.6% were totally preventable, 9.6% were probably preventable, and only 0.8% were not avoidable. Factors that would reduce the high rate of maternal mortality in this region include more widespread use of prenatal care, training of traditional birth attendants in asepsis, referral of high-risk pregnancies, and improved transportation in rural areas.

    Recent evidence indicates that perinatal exposure to maternal obesity, metabolic disease, including diabetes and hypertension, and unhealthy maternal diet has a long-term impact on offspring behavior and physiology. During the past three decades, the prevalence of both obesity and neuropsychiatric disorders has rapidly increased. Epidemiologic studies provide evidence that maternal obesity and metabolic complications increase the risk of attention deficit hyperactivity disorder (ADHD), autism spectrum disorders, anxiety, depression, schizophrenia, eating disorders (food addiction, anorexia nervosa, and bulimia nervosa), and impairments in cognition in offspring. Animal models of maternal high-fat diet (HFD) induced obesity also document persistent changes in offspring behavior and impairments in critical neural circuitry. Animals exposed to maternal obesity and HFD consumption display hyperactivity, impairments in social behavior, increased anxiety-like and depressive-like behaviors, substance addiction, food addiction, and diminished cognition. During development, these offspring are exposed to elevated levels of nutrients (fatty acids, glucose), hormones (leptin, insulin), and inflammatory factors (C-reactive protein, interleukin, and tumor necrosis factor). Such factors appear to permanently change neuroendocrine regulation and brain development in offspring. In addition, inflammation of the offspring brain during gestation impairs the development of neural pathways critical in the regulation of behavior, such as serotoninergic, dopaminergic, and melanocortinergic systems. Dysregulation of these circuits increases the risk of mental health disorders. Given the high rates of obesity in most developed nations, it is critical that the mechanisms by which maternal obesity programs offspring behavior are thoroughly characterized. Such knowledge will be critical in the development of preventative strategies and therapeutic interventions. PMID:26150767

    The relationship between maternal intrinsic factors and placental traits was investigated on three Southern Mediterranean breed of sheep; Cukurova Assaf (CA), Cukurova (C) and Cukurova Meat Sheep (CMS). The effect of parity and birth type were also considered in the study as a potential influencing factor. Our hypothesis was to show that while differences in placental traits between breed, parity and birth type affected lamb condition and survivability, its correlation to maternal intrinsic behavioral factors may also be a strong indicator. The study found breed related differences of maternal behavioral factors and also showed significant correlation of these behavioral patterns to various placental traits. It confirmed earlier findings that parity played a major role in the refinement of these behavioral patterns. Significant differences in birth weight (P<0.05), placental weight (P<0.05), number of cotyledons (P<0.01) and cotyledon length (P<0.05) was seen between breeds. Cotyledon weight (P<0.05), width (P<0.01) and length (P<0.05) were found to differ by parity. Breed and parity interaction significantly influenced cotyledon quantity. While we detected breed specific differences in relation to maternal intrinsic factors we also noticed significant variance within breeds to these behavioral patterns when linked to placental traits. Further study is required on the correlation between placental traits and postnatal behavior on not just the ewes but also on their lambs. This could have a significant bearing on how producers manage and maximize lamb survivability. PMID:23602010

  4. Levels of Polycyclic Aromatic Hydrocarbons in Maternal Serum and Risk of Neural Tube Defects in Offspring

    2015-01-01

    Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, and have been reported to be a risk factor for human neural tube defects (NTDs). We investigated the relationship between PAH concentrations in maternal serum and NTD risk in offspring using a case-control study design, and explored the link between PAH concentrations to household energy usage characteristics and life styles. One hundred and seventeen women who had NTD-affected pregnancies (cases) and 121 women who delivered healthy infants (controls) were recruited in Northern China. Maternal blood samples were collected at pregnancy termination or at delivery. Twenty-seven PAHs were measured by gas chromatography–mass spectrometry. The concentrations of 13 individual PAHs detected were significantly higher in the cases than in the controls. Clear dose–response relationships between concentrations of most individual PAHs and the risk of total NTDs or subtypes were observed, even when potential covariates were adjusted for. High-molecular-weight PAHs (H-PAHs) showed higher risk than low-molecular-weight PAHs (L-PAHs). No associations between PAH concentrations and indoor life styles and energy usage characteristics were observed. It was concluded that maternal exposure to PAHs was associated with an increased risk of NTDs, and H-PAHs overall posed a higher risk for NTDs than L-PAHs. PMID:25488567

    OBJECTIVES: This study sought to identify characteristics of high-risk pregnant women that predicted long-term participation in a home visitation program. METHODS: Data regarding sociodemographic characteristics, perceived needs, psychological functioning, substance use, and informal social support were collected prospectively from 152 short-term and 221 long-term program participants. RESULTS: In comparison with short-term participants, long-term participants were more likely to have been African American, married, nonsmokers, and enrolled in the program during their second trimester of pregnancy, and they were more likely to have had emotional and instrumental support needs. CONCLUSIONS: Women with greater social support needs and healthier behaviors were more receptive to long-term home visitation than other women. PMID:10630150

    Preeclampsia, a hypertensive disorder of pregnancy is estimated to complicate 2%–8% of pregnancies and remains a principal cause of maternal and fetal morbidity and mortality. Preeclampsia may present at any gestation but is more commonly encountered in the third trimester. Multiple risk factors have been documented, including: family history, nulliparity, egg donation, diabetes, and obesity. Significant progress has been made in developing tests to predict risk of preeclampsia in pregnancy, but these remain confined to clinical trial settings and center around measuring angiogenic profiles, including placental growth factor or newer tests involving metabolomics. Less progress has been made in developing new treatments and therapeutic targets, and aspirin remains one of the few agents shown to consistently reduce the risk of developing preeclampsia. This review serves to discuss recent advances in risk factor identification, prediction techniques, and management of preeclampsia in antenatal, intrapartum, and postnatal patients. PMID:25767405

    To determine atrial natriuretic factor (ANF) concentrations in the circulation and body fluids of adult pregnant sheep and their fetuses, pregnant ewes were anesthetized with pentobarbital sodium, and the fetuses were exteriorized for sampling. ANF concentration, as measured by radioimmunoassay, was 47 +/- 6 (SE) pg/ml in maternal plasma, which was significantly higher than the 15 +/- 3 pg/ml in maternal urine. In the fetus, plasma ANF concentration was 265 +/- 49 pg/ml, 5.6 times that in maternal plasma. No umbilical arterial and venous difference in ANF concentration was observed. Fetal urine ANF concentration was significantly lower than that in fetal plasma, and was similar to that measured in amniotic and allantoic fluid. In chronically catheterized maternal and fetal sheep, fetal plasma ANF was again 5.1 times that in maternal plasma, and these levels were not different from those measured in acutely anesthetized animals. These results demonstrate that immunoreactive ANF is present in the fetal circulation at levels higher than those found in the mother. The low concentration of ANF in fetal urine suggests that ANF is probably metabolized and/or reabsorbed by the fetal kidney.

    A demographic study carried out in a rural area of the Gambia between January 1993 and December 1998 recorded 74 deaths among women aged 15-49 years. Reported here is an estimation of maternal mortality among these 74 deaths based on a survey of reproductive age mortality, which identified 18 maternal deaths by verbal autopsy. Over the same period there were 4245 live births in the study area, giving a maternal mortality ratio of 424 per 100,000 live births. This maternal mortality estimate is substantially lower than estimates made in the 1980s, which ranged from 1005 to 2362 per 100,000 live births, in the same area. A total of 9 of the 18 deaths had a direct obstetric cause--haemorrhage (6 deaths), early pregnancy (2), and obstructed labour (1). Indirect causes of obstetric deaths were anaemia (4 deaths), hepatitis (1), and undetermined (4). Low standards of health care for obstetric referrals, failure to recognize the severity of the problem at the community level, delays in starting the decision-making process to seek health care, lack of transport, and substandard primary health care were identified more than once as probable or possible contributing factors to these maternal deaths.

    Objective We utilized an updated nationally representative database to examine associations between maternal age and prevalence of maternal morbidity during complications of labor and delivery. Study design We used hospital inpatient billing data from the 2009 United States Nationwide Inpatient Sample (NIS), part of the Healthcare Cost and Utilization Project (HCUP). To determine whether the likelihood that maternal morbidity during complications of labor and delivery differed among age groups, separate logistic regression models were run for each complication. Age was the main independent variable of interest. Results In analyses that controlled for demographics and clinical confounders, we found that complications with the highest odds among women, 11–18 years of age, compared to 25–29 year old women, included preterm delivery, chorioamnionitis, endometritis, and mild preeclampsia. Pregnant women who were 15–19 years old had greater odds for severe preeclampsia, eclampsia, postpartum hemorrhage, poor fetal growth, and fetal distress. Pregnant women who were ≥35 years old had greater odds for preterm delivery, hypertension, superimposed preeclampsia, severe preeclampsia, and decreased risk for chorioamnionitis. Older women (≥40 years old) had increased odds for mild preeclampsia, fetal distress, and poor fetal growth. Conclusions Our findings underscore the need for pregnant women to be aware of the risks associated with extremes of age so that they can watch for signs and symptoms of such complications.

    Perioperative anaphylactic as well as anaphylactoid reactions can be elicited by drugs, diagnostic agents, antiseptics, disinfectants and latex. In some individuals, allergic reactions occur in the absence of any evident risk factor. Previous history of specific safe exposure to a product does not permit to exclude the risk of having a reaction. We have systematically reviewed characteristics in the patient's history or clinical parameters that affect the risk of developing reactions during anesthesia. Evidence shows that patients with previous unexplained reaction during anesthesia are at risk for perioperative allergic reactions. An allergic reaction to an agent is associated with previous reaction to a product that is related with the culprit agent. Multiple surgery procedures, professional exposure to latex and allergy to fruit are associated with an increased frequency of latex allergy. It has been shown that in some instances, allergic perioperative reactions may be more common in atopic patients and in females. PMID:22014923

    Importance There is a well-described association between maternal diabetes and risk of congenital heart disease (CHD) in offspring. Though the clinical diagnoses of Type 2 diabetes or gestational diabetes are strong risk factors for CHD, sub-clinical abnormalities of glucose and insulin metabolism are common within the general population and could also confer risk for CHD. Objective We explored the potential association of two different CHD phenotypes in offspring with midpregnancy measures of glucose and insulin. Design, Setting, and Participants This is a case-control study from a cohort of 277 pregnant women in southern and central California carrying infants with tetralogy of Fallot (ToF) (n=55), d-transposition of the great arteries (dTGA) (n=42), or normal infants without CHD (n=180), Exposures Measurement of blood analytes related to maternal glucose metabolism taken from random non-fasting second trimester blood samples. Main Outcome and Measures We hypothesize that continuous measures of blood analytes related to maternal diabetes are related to odds of cardiac malformations. We measured serum insulin by a validated radioimmunoassay and glucose levels. Multivariable logistic regression models estimated the association between these levels and case status. Results Relative to maternal blood glucose levels of infants without cardiac malformations, we observed that maternal blood glucose levels in models including insulin were strongly associated with odds of ToF (adjusted Odds Ratio 7.54, 95%CI 2.30–24.69), but not with dTGA (adjusted OR 1.16, 95%CI 0.28–4.79). Conclusions & Relevance These results represent a direct correlation of glucose as a continuous variable to odds of specific cardiac malformations. The association between serum glucose and odds of ToF indicates the need for additional epidemiological and mechanistic investigations into the risk conferred by insulin signaling and glucose metabolism during early pregnancy.

    Background Maternal body mass and the presence of diabetes mellitus are probable risk factors for neural tube defects (NTDs). The association between maternal ethnicity and the risk of NTDs remains poorly understood, however. Methods We performed a retrospective population-based study and included all women in Ontario who underwent antenatal maternal screening (MSS) at 15 to 20 weeks' gestation between 1994 and late 2000. Self-declared maternal date of birth, ethnicity and weight and the presence of pregestational diabetes mellitus were recorded in a standardized fashion on the MSS requisition sheet. NTDs were detected antenatally by ultrasonography or fetal autopsy and postnatally by considering all live and stillborn affected infants beyond 20 weeks' gestation. The risk of open NTD was evaluated across the 5 broad ethnic groups used for MSS, with white ethnicity as the referent. Results Compared with white women (n = 290 799), women of First Nations origin (n = 1551) were at increased associated risk of an NTD-affected pregnancy (adjusted odds ratio [OR] 5.2, 95% confidence interval [CI] 2.1–12.9). Women of other ethnic origins were not at increased associated risk compared with white women (women of Asian origin [n = 75 590]: adjusted OR 0.9, 95% CI 0.6–1.3; black women [n = 25 966]: adjusted OR 0.6, 95% CI 0.3–1.1; women of “other” ethnic origin [n = 10 009]: adjusted OR 0.1, 95% CI 0.02–0.9). Interpretation The associated risk of NTD-affected pregnancies was higher among women of First Nations origin than among women of other ethnic origins. The mechanisms for this discrepancy should be explored. PMID:15313993

  16. Risk Factors in Stroke

    In the United States, stroke accounts for 160,000 annual deaths; only 16% of the 1.8 million stroke survivors are fully independent. The incidence of stroke increases with age. Hemorrhagic strokes outnumber ischemic strokes before age 15. Japanese men in this country have a lower stroke mortality than their age peers in Japan. Excessive stroke mortality for US nonwhites may not be entirely due to the greater prevalence of hypertension among blacks. Hypertension emerges as the single most powerful and reversible risk factor in stroke and for survival after stroke. Impaired cardiac function is the second most important precursor of stroke. The recurrence of stroke in survivors is high. The frequency of completed stroke is high in persons with transient ischemic attacks, but not in those with asymptomatic carotid bruits. Other reversible risk factors are smoking, the use of oral contraceptives, alcoholic excess, a low level of physical activity, blood hyperviscosity and drug abuse. PMID:3898597

    Breast cancer is the most frequently diagnosed neoplastic disease in women around menopause often leading to a significant reduction of these women's ability to function normally in everyday life. The increased breast cancer incidence observed in epidemiological studies in a group of women actively participating in social and professional life implicates the necessity of conducting multidirectional studies in order to identify risk factors associated with the occurrence of this type of neoplasm. Taking the possibility of influencing the neoplastic transformation process in individuals as a criterion, all the risk factors initiating the process can be divided into two groups. The first group would include inherent factors such as age, sex, race, genetic makeup promoting familial occurrence of the neoplastic disease or the occurrence of benign proliferative lesions of the mammary gland. They all constitute independent parameters and do not undergo simple modification in the course of an individual's life. The second group would include extrinsic factors conditioned by lifestyle, diet or long-term medical intervention such as using oral hormonal contraceptives or hormonal replacement therapy and their influence on the neoplastic process may be modified to a certain degree. Identification of modifiable factors may contribute to development of prevention strategies decreasing breast cancer incidence. PMID:26528110

    In a broad range of species—including humans—it has been demonstrated that telomere length declines throughout life and that it may be involved in cell and organismal senescence. This potential link to ageing and thus to fitness has triggered recent interest in understanding how variation in telomere length is inherited and maintained. However, previous studies suffer from two main drawbacks that limit the possibility of understanding the relative importance of genetic, parental and environmental influences on telomere length variation. These studies have been based on (i) telomere lengths measured at different time points in different individuals, despite the fact that telomere length changes over life, and (ii) parent–offspring regression techniques, which do not enable differentiation between genetic and parental components of inheritance. To overcome these drawbacks, in our study of a songbird, the great reed warbler, we have analysed telomere length measured early in life in both parents and offspring and applied statistical models (so-called ‘animal models') that are based on long-term pedigree data. Our results showed a significant heritability of telomere length on the maternal but not on the paternal side, and that the mother's age was positively correlated with their offspring's telomere length. Furthermore, the pedigree-based analyses revealed a significant heritability and an equally large maternal effect. Our study demonstrates strong maternal influence on telomere length and future studies now need to elucidate possible underlying factors, including which types of maternal effects are involved.

    BACKGROUND Animal studies have shown that high doses of caffeine might cause congenital limb deficiencies (LDs); however, no epidemiologic studies have explored this relation. METHODS This case-control study assessed associations between maternal dietary caffeine and congenital LDs using data from the National Birth Defects Prevention Study (NBDPS), with 844 LD cases and 8069 controls from 1997 to 2007. Caffeine intakes from beverages (coffee, tea, and soda) and chocolate combined and by beverage type were examined. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated for subtypes of isolated LDs (no additional major anomalies) and LDs with other major anomalies separately, comparing the odds of 10 to <100, 100 to <200, 200 to <300, and 300+ mg/day total caffeine intake to 0 to <10 mg/day. RESULTS All total dietary caffeine intake categories of 10 mg/day and above were marginally associated with odds of all isolated LDs combined (aOR, 1.4–1.7), isolated longitudinal LDs (aOR, 1.2–1.6), and isolated transverse LDs (aOR, 1.3–1.8) compared to the lowest intake category. A dose-response pattern for total dietary caffeine intake was not observed. CONCLUSIONS A weak increased risk of congenital LDs associated with maternal dietary caffeine consumption was observed in this study; however, risk did not vary by amount of caffeine consumed.

    2016-01-01

    Steroidogenic factor 1 (SF-1), officially designated NR5A1, is essential for gonadal and adrenal development and for the normal structure of the ventromedial hypothalamus (VMH), as demonstrated by SF-1 knockout mice (SF-1 KO), but much less is known about the possible effects of haploinsufficiency of the SF-1 gene. In the present study, maternal behavior in SF-1 KO heterozygous mice was evaluated. Behavioral tests revealed that SF-1 KO heterozygous females have impaired maternal behavior. In comparison to wild-type (WT) females, SF-1 KO heterozygous females retrieved significantly fewer pups into their nests, latency to retrieve and crouch over the pups was longer, and their nests were lower quality. As suggested by previous studies full dosage of SF-1 gene is needed for appropriate stress response and expression of brain-derived neurotrophic factor (BDNF) in the brain, and this might present a mechanism through which maternal behavior in SF-1 KO heterozygous females is impaired.

    Immunoglobulins cannot cross the placenta in pregnant sows. Neonatal pigs are therefore agammaglobulinemic at birth and, although immunocompetent, they cannot mount rapid immune responses at systemic and mucosal sites. Their survival depends directly on the acquisition of maternal immunity via colostrum and milk. Protection by maternal immunity is mediated by a number of factors, including specific systemic humoral immunity, involving mostly maternal IgG transferred from blood to colostrum and typically absorbed within the first 36 h of life. Passive mucosal immunity involves local humoral immunity, including the production of secretory IgA (sIgA), which is transferred principally via milk until weaning. The mammary gland (MG) produces sIgA, which is, then secreted into the milk via the poly-Ig receptor (pIgR) of epithelial cells. These antibodies are produced in response to intestinal and respiratory antigens, including pathogens and commensal organisms. Protection is also mediated by cellular immunity, which is transferred via maternal cells present in mammary secretions. The mechanisms underlying the various immunological links between MG and the mucosal surfaces involve hormonally regulated addressins and chemokines specific to these compartments. The enhancement of colostrogenic immunity depends on the stimulation of systemic immunity, whereas the enhancement of lactogenic immunity depends on appropriate stimulation at induction sites, an increase in cell trafficking from the gut and upper respiratory tract to the MG and, possibly, enhanced immunoglobulin production at the effector site and secretion in milk. In addition, mammary secretions provide factors other than immunoglobulins that protect the neonate and regulate the development of mucosal immunity--a key element of postnatal adaptation to environmental antigens.

    Objective To assess the risks and benefits associated with caesarean delivery compared with vaginal delivery. Design Prospective cohort study within the 2005 WHO global survey on maternal and perinatal health. Setting 410 health facilities in 24 areas in eight randomly selected Latin American countries; 123 were randomly selected and 120 participated and provided data Participants 106 546 deliveries reported during the three month study period, with data available for 97 095 (91% coverage). Main outcome measures Maternal, fetal, and neonatal morbidity and mortality associated with intrapartum or elective caesarean delivery, adjusted for clinical, demographic, pregnancy, and institutional characteristics. Results Women undergoing caesarean delivery had an increased risk of severe maternal morbidity compared with women undergoing vaginal delivery (odds ratio 2.0 (95% confidence interval 1.6 to 2.5) for intrapartum caesarean and 2.3 (1.7 to 3.1) for elective caesarean). The risk of antibiotic treatment after delivery for women having either type of caesarean was five times that of women having vaginal deliveries. With cephalic presentation, there was a trend towards a reduced odds ratio for fetal death with elective caesarean, after adjustment for possible confounding variables and gestational age (0.7, 0.4 to 1.0). With breech presentation, caesarean delivery had a large protective effect for fetal death. With cephalic presentation, however, independent of possible confounding variables and gestational age, intrapartum and elective caesarean increased the risk for a stay of seven or more days in neonatal intensive care (2.1 (1.8 to 2.6) and 1.9 (1.6 to 2.3), respectively) and the risk of neonatal mortality up to hospital discharge (1.7 (1.3 to 2.2) and 1.9 (1.5 to 2.6), respectively), which remained higher even after exclusion of all caesarean deliveries for fetal distress. Such increased risk was not seen for breech presentation. Lack of labour was a risk factor

    Background: Gestational diabetes mellitus (GDM) is a metabolic disorder defined as glucose intolerance with the onset or first recognition during pregnancy. Women with GDM are at increased risk for adverse obstetric and perinatal outcome. The complications associated with GDM can be prevented by early recognition, intense monitoring and proper treatment. Aims: The present study was done to screen the high-risk pregnancy group for GDM, to find the incidence of abnormal results on screening and to correlate the abnormal results with the maternal and fetal outcomes. The study was done in a tertiary care hospital and teaching institute. It was a prospective cohort study. Materials and Methods: Selective screening for GDM was done in 150 pregnant women with high-risk factors. Screening was done with 50 g glucose challenge test (GCT) after 18 weeks, and if GCT was negative then the test was repeated after 28 weeks of pregnancy. The patients who were having an abnormal GCT were subjected to 100 g oral glucose tolerance test (OGTT). All GDM patients were followed up and treated with diet and/or insulin therapy till delivery to know maternal and fetal outcomes. The period of study was from April 2008 to March 2009. Results: 7.3% of study population was OGCT positive. 6% of the study population was OGTT positive. Age >25 years, obesity, family history of DM, and past history of GDM were the risk factors significantly associated with GDM. One newborn had hypoglycemia and one had hyperbilirubinemia. The fetal and maternal outcome in GDM patients was good in our study due to early diagnosis and intervention. Conclusion: Women with GDM are at an increased risk for adverse obstetric and perinatal outcome. The increased morbidity in GDM is preventable by meticulous antenatal care. PMID:22701851

    Objective: It is important to identify the possible risk factors for the occurrence of large for gestational age (LGA) in newborns and to determine the effect of birth weight and metabolic parameters on subsequent growth. We aimed to determine the effects of maternal weight, weight gain during pregnancy, maternal hemoglobin A1c (HbA1c), C-peptide and insulin as well as cord C-peptide and insulin levels on birth weight and postnatal growth during the first two years of life. Methods: Healthy, non-diabetic mothers and term singleton newborns were included in this prospective case-control cohort study. Fasting maternal glucose, HbA1c, C-peptide and insulin levels were studied. Cord blood was analyzed for C-peptide and insulin. At birth, newborns were divided into two groups according to birth size: LGA and appropriate for GA (AGA). Infants were followed at six-month intervals for two years and their length and weight were recorded. Results: Forty LGA and 43 AGA infants were included in the study. Birth weight standard deviation score (SDS) was positively correlated with maternal body mass index (BMI) before delivery (r=0.2, p=0.04) and with weight gain during pregnancy (r=0.2, p=0.04). In multivariate analyses, the strongest association with macrosomia was a maternal C-peptide level >3.85 ng/mL (OR=20). Although the LGA group showed decreased growth by the 6-month of follow-up, the differences between the LGA and AGA groups in weight and length SDS persisted over the 2 years of follow-up. Conclusion: The control of maternal BMI and prevention of overt weight gain during pregnancy may prevent excessive birth weight. The effect of the in utero metabolic environment on the weight and length SDS of infants born LGA persists until at least two years of age. PMID:26831549

    Intraventricular hemorrhage (IVH) is an important cause of brain injury in premature neonates. Current study tries to define associated risk factors of IVH in preterm neonates in Aliasghar Children Hospital during 2008 to 2011. In this study, the risk factors have been evaluated in premature neonates with IVH, who had at least one brain sonography since their admission in NICU. A total of 63 premature neonates with IVH were assessed. Mean gestational age was 29.81 (24-34) weeks and mean birth weight was 1290.83±382.96 gr. Other risk factors such as sex, mode of delivery, history of using infertility drugs, maternal disease, maternal hypertension and preeclampsia, lumbar puncture, ventilator therapy and pneumothorax were considered. Because no absolute treatment for IVH is available, identifying risk factors is important in prevention and management of IVH. PMID:25421841

    There are many established risk factors for babies who are small for gestational age (SGA) by population birth weight centiles (usually defined as <10th centile). The confirmed maternal risk factors include short stature, low weight, Indian or Asian ethnicity, nulliparity, mother born SGA, cigarette smoking and cocaine use. Maternal medical history of: chronic hypertension, renal disease, anti-phospholipid syndrome and malaria are associated with increased SGA. Risk factors developing in pregnancy include heavy bleeding in early pregnancy, placental abruption, pre-eclampsia and gestational hypertension. A short or very long inter-pregnancy interval, previous SGA infant or previous stillbirth are also risk factors. Paternal factors including changed paternity, short stature and father born SGA also contribute. Factors associated with reduced risk of SGA or increased birth weight include high maternal milk consumption and high intakes of green leafy vegetables and fruit. Future studies need to investigate risk factors for babies SGA by customised centiles as these babies have greater morbidity and mortality than babies defined as SGA by population centiles.

    Little is known about the ways in which the accumulation of maternal factors increases or reduces risk for girls' disruptive behavior during preadolescence. In the current study, maternal risk and promotive factors and the severity of girls' disruptive behavior were assessed annually among girls' ages 7-12 in an urban community sample (N = 2043). Maternal risk and promotive factors were operative at different time points in girls' development. Maternal warmth explained variance in girls' disruptive behavior, even after controlling for maternal risk factors and relevant child and neighborhood factors. In addition, findings supported the cumulative hypothesis that the number of risk factors increased the chance on girls' disruptive behavior disorder (DBD), while the number of promotive factors decreased this probability. Daughters of mothers with a history of Conduct Disorder (CD) were exposed to more risk factors and fewer promotive factors compared to daughters of mothers without prior CD. The identification of malleable maternal factors that can serve as targets for intervention has important implications for intergenerational intervention. Cumulative effects show that the focus of prevention efforts should not be on single factors, but on multiple factors associated with girls' disruptive behavior. PMID:22127641

    Prenatal psychosocial stressors may increase the risk of wheeze in young offspring, yet little attention has been given to the effects that maternal ethnicity may have on this relationship. From a population-based cohort of 1193 children, we assessed the effect of maternal prenatal stressors on the risk of lifetime wheeze in young offspring. We further studied whether maternal Latina ethnicity modified these associations. The risk of wheeze in the offspring was increased from high levels of pregnancy anxiety (aRR 1.40, 95 % CI 1.07, 1.83), negative life events (aRR 1.36, 95 % CI 1.06, 1.75), or low paternal support (aRR 1.41, 95 % CI 1.02, 1.96). The risk of lifetime wheeze was stronger in the offspring of Latina mothers than of White mothers for these same stressors. Multiple maternal prenatal stressors are associated with increased risk of lifetime wheeze in young offspring, with slight effect modification by Latina ethnicity. PMID:26343048

    Background The major causes of maternal and perinatal deaths are mostly pregnancy related. However, there are several predisposing factors for the increased risk of pregnancy related complications and deaths in developing countries. The objective of this review was to grossly estimate the effect of selected socioeconomic and cultural factors on maternal mortality, stillbirths and neonatal mortality in Ethiopia. Methods A comprehensive literature review was conducted focusing on the effect of total fertility rate (TFR), modern contraceptive use, harmful traditional practice, adult literacy rate and level of income on maternal and perinatal mortalities. For the majority of the data, regression analysis and Pearson correlation coefficient were used as a proxy indicator for the association of variables with maternal, fetal and neonatal mortality. Results Although there were variations in the methods for estimation, the TFR of women in Ethiopia declined from 5.9 to 4.8 in the last fifteen years, which was in the middle as compared with that of other African countries. The preference of injectable contraceptive method has increased by 7-fold, but the unmet contraceptive need was among the highest in Africa. About 50% reduction in female genital cutting (FGC) was reported although some women's attitude was positive towards the practice of FGC. The regression analysis demonstrated increased risk of stillbirths, neonatal and maternal mortality with increased TFR. The increased adult literacy rate was associated with increased antenatal care and skilled person attended delivery. Low adult literacy was also found to have a negative association with stillbirths and neonatal and maternal mortality. A similar trend was also observed with income. Conclusion Maternal mortality ratio, stillbirth rate and neonatal mortality rate had inverse relations with income and adult education. In Ethiopia, the high total fertility rate, low utilization of contraceptive methods, low adult

    Objectives of this study were to ascertain risk and protective factors in the adjustment of 78 school-age and teenage offspring of opioid- and cocaine-abusing mothers. Using a multimethod, multiinformant approach, child outcomes were operationalized via lifetime psychiatric diagnoses and everyday social competence (each based on both mother and child reports), and dimensional assessments of symptoms (mother report). Risk/protective factors examined included the child sociodemographic attributes of gender, age, and ethnicity, aspects of maternal psychopathology, and both mother's and children's cognitive functioning. Results revealed that greater child maladjustment was linked with increasing age, Caucasian (as opposed to African American) ethnicity, severity of maternal psychiatric disturbance, higher maternal cognitive abilities (among African Americans) and lower child cognitive abilities (among Caucasians). Limitations of the study are discussed, as are implications of findings for future research. PMID:9524811

    Abstract Background This study examined the association between social, demographic, and psychologic factors and smoking status among Appalachian Ohio women. A secondary aim examined whether specific factors could be identified and segmented for future tailored treatment of tobacco dependence. Methods A cross-sectional survey (n=570) obtained information about social, demographic, and psychologic factors and smoking. Logistic regression described associations between these characteristics and smoking status. Chi-square automatic interaction detection (CHAID) analyses identified subgroups at risk for smoking. Results Fifty-two percent never smoked, with 20.5% and 27.5% categorized as former and current smokers, respectively. Women with low adult socioeconomic position (SEP) were more likely to smoke (odds ratio [OR] 3.05, 95% confidence interval [CI] 1.74-5.34) compared to high SEP women. Other factors associated with current smoking included age 31–50 (OR 2.30, 95% CI 1.22-4.33), age 18–30 (OR 3.29, 95% CI 1.72-5.34), Center for Epidemiologic Studies Depression scale (CES-D) score≥16 (OR 1.99, 95% CI 1.31-3.05), and first pregnancy at age<20 (OR 1.74, 95% CI 1.14-2.66). The prevalence of smoking was 50% among those with four or more risk factors compared to 10% for those reporting no risk factors. CHAID analyses identified low adult SEP and depressive symptoms as the combination of risk factors most strongly associated with smoking; 49.3% of women in this subgroup currently smoked. Conclusions Low SEP in adulthood, maternal circumstances, and depressive symptoms are associated with current smoking. Tailored cessation interventions that address these risk factors should be developed and further evaluated in an attempt to reduce disparities in smoking prevalence among this vulnerable group of women.

    OBJECTIVES. This study identified factors predicting adherence to medical recommendations in maternal phenylketonuria, which can result in severe fetal damage. METHODS. Sixty-nine women with phenylketonuria, 68 of their acquaintances, and 69 women with diabetes mellitus were interviewed annually for 5 years. A model in which each stage in the maternal phenylketonuria life cycle represented a treatment-related goal provided a means to assess adherence. RESULTS. At the stages of prevention of unplanned pregnancy, treatment initiation, and diet continuation throughout pregnancy, attitudes and social support were associated with adherence to medical recommendations. No specific variables were associated with outcome at reproductive decision making, but women with phenylketonuria were more likely to delay making a decision, resulting in unplanned and, hence, untreated or late-treated pregnancy. CONCLUSIONS. Women with phenylketonuria differed from their acquaintances and diabetic women in many respects, suggesting that special programs are needed. Greater emphasis on reproductive decision making is especially needed. Interventions that focus on improving social support networks and attitudes about treatment may increase adherence to recommendations. PMID:7503337

    This study, following Camperio-Ciani, Corna, and Capiluppi [(2004), Proceedings of the Royal Society of London, Series B, Biological Sciences, 271, 2217-2221] aimed to examine the familial history of male homosexuality, and test the so-called "fertile female" hypothesis for this trait in a contemporary British sample. Using a comparative survey design, we found that white (comprising those of Anglo-European descent) and non-white (comprising ethnic "Blacks, "South Asians," "East Asians," "Hispanics," and "Others") homosexual men (n = 147) had a significant excess of maternal but not paternal line male homosexual relatives compared to heterosexual men (n = 155). We also found significantly elevated fecundity of maternal aunts of white homosexual men compared to white heterosexual men, whereas non-white heterosexual men showed elevated fecundities of almost every class of relative compared to non-white homosexual men. No significant excess of older brothers was found in homosexual compared to heterosexual men, irrespective of ethnic grouping. These data were discussed in relation to possible population-related factors in evolutionary explanations for human male homosexuality. PMID:17665299

The purpose of this study was to explore changes related to maternal fatigue from pregnancy to postpartum and the factors influencing fatigue. This prospective longitudinal study surveyed 197 pregnant women beyond 24 gestational weeks monthly until one month postpartum. The Multidimensional Assessment of Fatigue scale and one question about fatigue were used. Women at late pregnancy experienced a significant increase in level of fatigue, which remained high after childbirth. Those who were not happy about the pregnancy or were multiparas experienced a higher level of prenatal fatigue than their counterparts. At postpartum, mothers who were unemployed, had no one to help with childcare, or felt that the baby's night-time sleep pattern was a serious problem had a higher level of fatigue. Interventions can be planned and implemented at early pregnancy to reduce the prevalence of fatigue. Encouraging pregnant women to share experiences and thoughts about pregnancy and being a mother is suggested. Further studies that evaluate culturally sensitive instruments for fatigue are needed.

    Risk factor modification remains as the principal aspect of care for stroke prevention. Understanding of risk factors has advanced and several options are now available to treat modifiable risk factors. However, effective treatment remains a challenging task in clinical practice. Prevention begins with awareness of risk factors by patients and clinicians. Risk factor assessment along with overall stroke risk estimation should be part of evaluation of patients with stroke, and used with careful clinical judgment. In this review we discuss the impact of modifiable traditional vascular risk factors on ischemic stroke, interventions for stroke prevention, and evidence for early treatment of risk factors where available as well as areas of research progress. Emphasis should be paid in education of patients, the community and medical personnel. Future research in the field of genetic determinants of vascular risk factors and stroke will increase our understanding of the underlying mechanisms of cerebrovascular disease and likely result in development of new therapies and individualized programs for stroke prevention.

  7. Comparing factors associated with maternal and adolescent reports of adolescent traumatic event exposure.

    Johnson, Sharon D

    2014-06-01

    Existing research indicates that there is very little agreement between youth and their parents on youth trauma exposure and subsequent treatment. Few studies, however, have attempted to examine factors that may contribute to this lack of agreement. This study addressed this gap by examining youth and maternal-reported youth traumatic event exposure using a sample of 100 urban, African American adolescent-maternal dyads. Cumulative report of youth potentially traumatic event exposure (57%) was higher than youth (41%) and maternal (27%) reports. Findings indicate that there was agreement for sexual assault, being shot or stabbed, and auto accidents. Maternal depression was the only factor that was associated with both youth and maternal report of youth qualifying event. Other factors that distinguished youth reports included maternal event exposure, substance use disorder, antisocial personality behaviors, and youth reports of arguments with the mother and running away from home. Implications for reconciling reports of trauma exposure among youth and their mothers are discussed. PMID:24206543

  8. Predicting Emotional and Social Competence during Early Childhood from Toddler Risk and Maternal Behavior

    2010-01-01

    The longitudinal associations between maternal parenting behavior and toddler risk with children’s emotional and social competence were examined during the transition to kindergarten, in a sample of 253 children. Toddler risk was characterized by early externalizing behavior and poor emotion regulation skills. Given that we were interested in the multiple pathways that may result in emotional and social competence, we examined the interactions among maternal parenting behavior and toddler risk. There were some significant interactions; although the pattern of results was not consistent across all competence outcomes. Maternal parenting behavior was not directly associated with children’s emotional and social competence. In some instances, maternal control has differential implications for children’s emotional and social competence dependent upon the child’s level of early risk and maternal positive parenting. Specifically, maternal control tended to be more detrimental for children’s emotional competence during the transition to kindergarten, when children exhibit higher levels of risk. Overall, it appears that there are multiple developmental pathways, depending on child and maternal characteristics that lead to early emotional and social competence. PMID:20102651

    Mother-child reminiscing, the process by which mothers and their children discuss past events and emotional experiences, has been robustly linked with child outcomes, including autobiographical memory. To advance previous work linking elaborative maternal reminiscing with child autobiographical memory specificity, the ability to generate and retrieve specific memories from one's past, it is essential to make distinctions among aspects of elaboration and to consider how maternal risk factors may influence the reminiscing context. The current study evaluated (a) an interaction between emotional and structural elaboration predicting child autobiographical memory specificity and (b) the potential moderating role of maternal adult attachment. Participants consisted of 95 preschool-aged children and their mothers. The sample was predominantly low income and racially diverse. Dyads completed a reminiscing task that was coded for emotional and structural elaboration. Mothers completed the Experiences in Close Relationships questionnaire (ECR-R) to assess attachment-related avoidance and anxiety, and children completed the Autobiographical Memory Test-Preschool Version (AMT-PV) to assess memory specificity. Results indicated that the association between structural reminiscing and child memory specificity was moderated by emotional elements of reminiscing. At high levels of emotional elaboration, mothers with high levels of structural elaboration had children with more specific memory than mothers with low levels of structural elaboration. Moreover, emotional elaboration (a) predicted less specific child memory without high structural support and (b) negatively predicted child specificity at high levels of maternal attachment avoidance and anxiety, a profile associated with fearful avoidance. Future directions and implications are discussed. PMID:26630033

  11. Adolescent mothers and child abuse potential: an evaluation of risk factors.

    PubMed

    Dukewich, T L; Borkowski, J G; Whitman, T L

    1996-11-01

    This research examines maternal and child factors that place adolescent mothers at risk for abusing their children. Using a longitudinal design, relationships among four risk factors (social supports, maternal psychological adjustment, maternal preparation for parenting, and child temperament), maternal psychological predisposition for aggressive coping (perceptions of stress and endorsements of punitive parenting), and maternal abuse potential were examined in a sample of 75 primiparous adolescent mothers and their children. Preparation for parenting, a construct which included knowledge and attitudes about children's development, was the strongest direct predictor of abuse potential; however, its effects were also partially mediated by the mother's psychological predisposition for aggressive coping. Similarly, the effects of child temperament on abuse were mediated by the mother's psychological predisposition for aggressive coping. Implications for designing intervention programs, and identifying at-risk adolescents, were also discussed. PMID:8958454

    Background/Objectives: In-utero exposures through adverse fetal programming are emerging as an important contributing factor to the epidemic of childhood obesity. This study examines the impact of in-utero exposure to caffeine on the risk of childhood obesity in offspring. Subjects/Methods: A prospective study of pregnant women with 15 years follow-up of their offspring was conducted to examine the impact of in-utero exposure to caffeine on the risk of childhood obesity. Maternal caffeine intake was prospectively ascertained during pregnancy and outcome measures (body mass index (BMI)) were ascertained from medical charts, with 17 BMI measurements per child, on average, during the follow-up period. Potential confounders including known perinatal risk factors for childhood obesity were adjusted for using the generalized estimating equations model with repeated measurements. Results: After controlling for potential confounders, compared with those without caffeine exposure, in-utero exposure to caffeine overall is associated with 87% increased risk of childhood obesity: odds ratio (OR) =1.87, 95% confidence interval (CI): 1.12–3.12. This association demonstrated a dose–response relationship: OR=1.77 (1.05–3.00) for maternal daily caffeine intake <150 mg per day, OR=2.37 (1.24–4.52) for caffeine intake ⩾150 mg per day during pregnancy, respectively. We also observed a linear relationship: every one unit increase (log10 scale) in the amount of maternal caffeine intake was associated with 23% increased risk of obesity in offspring. The dose–response relationship appears stronger for persistent obesity than for transitory obesity (occasional high BMI), and for girls than for boys. Conclusions: We observed an association of in-utero exposure to caffeine with increased risk of childhood obesity. If this observation is further replicated in other studies, the finding will contribute to the understanding of fetal programming of childhood diseases and

    Abstract Reducing maternal and child mortality is a priority in the Millennium Development Goals (MDGs), and will likely remain so after 2015. Evidence exists on the investments, interventions and enabling policies required. Less is understood about why some countries achieve faster progress than other comparable countries. The Success Factors for Women’s and Children’s Health studies sought to address this knowledge gap using statistical and econometric analyses of data from 144 low- and middle-income countries (LMICs) over 20 years; Boolean, qualitative comparative analysis; a literature review; and country-specific reviews in 10 fast-track countries for MDGs 4 and 5a. There is no standard formula – fast-track countries deploy tailored strategies and adapt quickly to change. However, fast-track countries share some effective approaches in addressing three main areas to reduce maternal and child mortality. First, these countries engage multiple sectors to address crucial health determinants. Around half the reduction in child mortality in LMICs since 1990 is the result of health sector investments, the other half is attributed to investments made in sectors outside health. Second, these countries use strategies to mobilize partners across society, using timely, robust evidence for decision-making and accountability and a triple planning approach to consider immediate needs, long-term vision and adaptation to change. Third, the countries establish guiding principles that orient progress, align stakeholder action and achieve results over time. This evidence synthesis contributes to global learning on accelerating improvements in women’s and children’s health towards 2015 and beyond. PMID:25110379

    Our aim was to clarify the perinatal outcomes of and risk factors for hypertension that is first detected after labor onset (labor onset hypertension, LOH), which may be a risk factor for eclampsia and stroke during labor. A total of 1349 parturient women who did not exhibit preeclampsia or gestational hypertension prior to labor were examined. The patients were classified into four groups: the normotensive (n=1023) (whose systolic blood pressure (SBP) remained below 140 mm Hg throughout labor), mild LOH (n=241) (whose maximum SBP during labor ranged from 140 to 159 mm Hg), severe LOH (n=66) (whose maximum SBP during labor ranged from 160 to 179 mm Hg) and emergent LOH groups (n=19) (whose maximum SBP during labor was greater than 180 mm Hg). The perinatal outcomes and patient characteristics of the four groups were compared. Twenty-four percent of the pregnant women who remained normotensive throughout pregnancy developed hypertension during labor. One of the patients in the emergent LOH group developed eclampsia. The blood pressure at delivery and frequencies of hypotensor use, interventional delivery and low Apgar scores differed significantly among the four groups. The following risk factors for severe/emergent LOH were extracted: being over 35 years old, a body mass index at delivery of >30, an SBP at 36 weeks' gestation of 130-134 mm Hg, an SBP at admission of 130-139 mm Hg, proteinuria (a score of 2+ on the dipstick test) and severe edema. The risk factors for severe/emergent LOH were identified in this study. In high risk cases, repeatedly measuring maternal blood pressure during delivery might help detect critical hypertension early.

    Objective To asses he association between intake of folate and B vitamins and the incidence of spontaneous abortion (SA) according to the maternal methylenetetrahydrofolate reductase (MTHFR) polymorphisms (677 C>T and 1298 A>C). Material and Methods We conducted a nested case-control study within a perinatal cohort of women recruited in the state of Morelos, Mexico. Twenty-three women with SA were compared to 74 women whose pregnancy survived beyond week 20th. Intake of folate and B vitamins respectively, was estimated using a validated food frequency questionnaire. Maternal MTHFR polymorphisms were determined by PCR-RFLP and serum homocysteine levels by HPLC. Results Carriers of MTHFR 677TT and 1298AC genotypes respectively showed an increased risk of SA (OR 677TT vs. CC/CT=5.0; 95% CI: 1.2, 20.9 and OR 1298 AC vs. AA=5.5; 95% CI: 1.1, 26.6). Conclusions Our results support the role of MTHFR polymorphisms as a risk factor for SA, regardless of dietary intake of B vitamins. PMID:19180309

    The objective of this study was to identify factors associated with weapon use in a group of filicidal women. Clinical data were gathered from the charts of sixty filicidal women evaluated at Michigan's Center for Forensic Psychiatry or through Connecticut's Psychiatric Security Review Board from 1970 to 1996. Factors associated with weapon use were determined using chi squares, ANCOVAS, and a logistic regression. Results were compared to national statistics for child homicide from the Department of Justice Uniform Crime Reports (UCR). Weapon was defined as knife or gun for the study. Weapons were used by one of four women in our study. Guns were used by 13% of filicidal women and knives by 12%. Odds ratio showed that psychotic women were eleven times more likely to kill their child with a weapon than their non-psychotic counterparts (11.2; p = .008). Psychosis was present in every mother who killed her child with a knife and in seven of eight women who killed their children with a gun. Younger children were less likely to be killed with weapons (ANCOVA; F = 8.28; p = .006). This finding was independent of presence or absence of maternal psychosis. These results show that psychotic women are more likely than non-psychotic women to kill their children with weapons. They also show that mothers are more likely to use weapons to kill older children than younger children. PMID:9608698

    2016-01-01

    Background and Objectives High maternity-related health care spending is often cited as an important barrier in utilizing quality health care during pregnancy and childbirth. This study has two objectives: (i) to measure the levels of expenditure on total maternity care in disaggregated components such as ANCs, PNCs, and Natal care expenditure; (ii) to quantify the extent of catastrophic maternity expenditure (CME) incurred by households and identify the factors responsible for it. Methods and Findings Data from the 71st round of the National Sample Survey (2014) was used to estimate maternity expenditure and its predictors. CME was measured as a share of consumption expenditure by different cut-offs. The two-part model was used to identify the factors associated with maternity spending and CME. The findings show that household spending on maternity care (US$ 149 in constant price) is much higher than previous estimates (US$ 50 in constant price). A significant proportion of households in India (51%) are incurring CME. Along with economic and educational status, type of health care and place of residence emerged as significant factors in explaining CME. Conclusion Findings from this study assume importance in the context of an emerging demand for higher maternity entitlements and government spending on public health care in India. To reduce CME, India needs to improve the availability and accessibility of better-quality public health services and increase maternity entitlements in line with maternity expenditure identified in this study.

    Several environmental exposures are associated with increased risk of coronary heart disease (CHD). Exposure to secondhand smoke may increase the risk by as much as 25% to 30%. Exposure to third hand smoke, residual components of tobacco smoke that remain in the environment after a cigarette is extinguished, also appears to increase risk. These residual components can remain in rooms and automobiles for up to 30 years and enter the body through the skin or via inhalation or ingestion. Exposure to particulate matter air pollution from automobile emissions, power plants, and other sources is yet another environmental risk factor for CHD, resulting in tens of thousands of deaths annually in the United States. Exposure to other environmental toxins, particularly bisphenol A and phthalates, also has been linked to CHD. There are sociodemographic risks for CHD, with numerous studies showing that lower socioeconomic status is associated with higher risk. Behavioral risk factors include poor diet, such as frequent consumption of fast food and processed meals; sleep disturbance; and psychological stress, particularly related to marital or work issues. Finally, although high alcohol consumption is associated with increased CHD risk, moderate alcohol consumption (ie, less than 1 to 2 drinks/day), particularly of wine and possibly beer, appears to reduce the risk.

    2013-01-01

    Birth defects (BDs) or congenital anomalies include all structural and functional alterations in embryonic or fetal development resulting from genetic, environmental or unknown causes, which result in physical and/or mental impairment. BDs occur in about 3% of newborn babies and in most cases of pregnancy loss. BDs are a very complex and heterogeneous group of single or multiple changes that, in most cases, are of unknown etiology. Among the risk factors are advanced maternal and paternal ages, parental consanguinity, teratogenic agents such as infectious agents and drugs, and poor nutrition, in particular folic acid deficiency. One of the consequences of these defects is the high death rate within the first year of life. Information on BDs is becoming increasingly more important throughout the world so that preventive measures can be taken. Knowledge of BDs enables the development of therapeutic and preventive strategies besides adequate genetic counseling.

    OBJECTIVES: Early infant mortality has not declined as rapidly as child mortality in many countries. Identification of risk factors for early infant mortality may help inform the design of intervention strategies. METHODS: Over the period 1994-97, 15,469 live-born, singleton infants in rural Nepal were followed to 24 weeks of age to identify risk factors for mortality within 0-7 days, 8-28 days, and 4-24 weeks after the birth. FINDINGS: In multivariate models, maternal and paternal education reduced mortality between 4 and 24 weeks only: odds ratios (OR) 0.28 (95% confidence interval (CI) = 0.12-0.66) and 0.63 (95% CI = 0.44-0.88), respectively. Miscarriage in the previous pregnancy predicted mortality in the first week of life (OR = 1.98, 95% CI = 1.37-2.87), whereas prior child deaths increased the risk of post-neonatal death (OR = 1.85, 95% CI 1.24-2.75). A larger maternal mid-upper arm circumference reduced the risk of infant death during the first week of life (OR = 0.88, 95% CI = 0.81-0.95). Infants of women who did not receive any tetanus vaccinations during pregnancy or who had severe illness during the third trimester were more likely to die in the neonatal period. Maternal mortality was strongly associated with infant mortality (OR = 6.43, 95% CI = 2.35-17.56 at 0-7 days; OR = 11.73, 95% CI = 3.82-36.00 at 8-28 days; and OR = 51.68, 95% CI = 20.26-131.80 at 4-24 weeks). CONCLUSION: Risk factors for early infant mortality varied with the age of the infant. Factors amenable to intervention included efforts aimed at maternal morbidity and mortality and increased arm circumference during pregnancy. PMID:14758431

    Objective To determine whether risk factors associated with Grade (Gr) 2–4 intraventricular hemorrhage (IVH) differs between African ancestry and white subjects. Study design Inborn, appropriate for gestational age (GA) infants with birth weights (BW) 500–1250 grams and exposed to >1 dose of antenatal steroids were enrolled in 24 neonatal intensive care units. Cases had Gr 2–4 IVH and controls matched for site, race and BW range had 2 normal ultrasounds read centrally. Multivariate logistic regression modeling identified factors associated with IVH across African ancestry and white race. Results Subjects included 579 African ancestry or white race infants with Gr 2–4 IVH and 532 controls. Mothers of African ancestry children were less educated, and white case mothers were more likely to have > 1 prenatal visit and have a multiple gestation (P ≤.01 for all). Increasing GA (P =.01), preeclampsia (P < .001), complete antenatal steroid exposure (P = .02), cesarean delivery (P < .001) and white race (P = .01) were associated with decreased risk for IVH. Chorioamnionitis (P = .01), Apgar< 3 at 5 min (P < .004), surfactant (P < .001) and high frequency ventilation (P < .001) were associated with increased risk for IVH. Among African ancestry infants, having >1 prenatal visit was associated with decreased risk (P = .02). Among white infants, multiple gestation was associated with increased risk (P < .001) and higher maternal education with decreased IVH risk (P < .05). Conclusion Risk for IVH differs between African ancestry and white infants and may be attributable to both race and health care disparities. PMID:24589078

    Kováčová, M; Kiňová, S

    2012-12-01

    Gravidity is a dynamic process and complications may occur at any stage and anytime during a thus far physiological gravidity. Such gravidity puts the mother, the foetus and, later, the newborn at a greater risk. The incidence of arterial hypertension is between 7 and 15% and is one of the 4 main causes of maternal and perinatal mortality. Cardiovascular stress test, such as gravidity, might help to identify women at a greater risk of cardiovascular diseases or with a subclinical vascular disease. Women with a history of preeclampsia are more likely to develop chronic arterial hypertension in the future either alone or associated with a cardiovascular disease. Arterial hypertension during gravidity should be considered as a risk factor for cardiovascular diseases during later stages of maternal life. Prevention of cardiovascular diseases should be a life-long aspiration. PMID:23427950

    PubMed Central

    2009-01-01

    Background Maternal health is one of the major worldwide health challenges. Currently, the unacceptably high levels of maternal mortality are a common subject in global health and development discussions. Although some countries have made remarkable progress, half of the maternal deaths in the world still take place in Sub-Saharan Africa where little or no progress has been made. There is no single simple, straightforward intervention that will significantly decrease maternal mortality alone; however, there is a consensus on the importance of a strong health system, skilled delivery attendants, and women's rights for maternal health. Our objective was to describe and determine different factors associated with the maternal mortality ratio in Sub-Saharan countries. Methods An ecological multi-group study compared variables between many countries in Sub-Saharan Africa using data collected between 1997 and 2006. The dependent variable was the maternal mortality ratio, and Health care system-related, educational and economic indicators were the independent variables. Information sources included the WHO, World Bank, UNICEF and UNDP. Results Maternal mortality ratio values in Sub-Saharan Africa were demonstrated to be high and vary enormously among countries. A relationship between the maternal mortality ratio and some educational, sanitary and economic factors was observed. There was an inverse and significant correlation of the maternal mortality ratio with prenatal care coverage, births assisted by skilled health personnel, access to an improved water source, adult literacy rate, primary female enrolment rate, education index, the Gross National Income per capita and the per-capita government expenditure on health. Conclusions Education and an effective and efficient health system, especially during pregnancy and delivery, are strongly related to maternal death. Also, macro-economic factors are related and could be influencing the others. PMID:20003411

    Infectious etiologies have been hypothesized for acute leukemias because of their high incidence in early childhood, but have seldom been examined for acute myeloid leukemia (AML). We conducted the first large cohort study to examine perinatal factors including season of birth, a proxy for perinatal infectious exposures, and risk of AML in childhood through young adulthood. A national cohort of 3,569,333 persons without Down syndrome who were born in Sweden in 1973-2008 were followed up for AML incidence through 2010 (maximum age 38 years). There were 315 AML cases in 69.7 million person-years of follow-up. We found a sinusoidal pattern in AML risk by season of birth (P < 0.001), with peak risk among persons born in winter. Relative to persons born in summer (June-August), incidence rate ratios for AML were 1.72 (95 % CI 1.25-2.38; P = 0.001) for winter (December-February), 1.37 (95 % CI 0.99-1.90; P = 0.06) for spring (March-May), and 1.27 (95 % CI 0.90-1.80; P = 0.17) for fall (September-November). Other risk factors for AML included high fetal growth, high gestational age at birth, and low maternal education level. These findings did not vary by sex or age at diagnosis. Sex, birth order, parental age, and parental country of birth were not associated with AML. In this large cohort study, birth in winter was associated with increased risk of AML in childhood through young adulthood, possibly related to immunologic effects of early infectious exposures compared with summer birth. These findings warrant further investigation of the role of seasonally varying perinatal exposures in the etiology of AML. PMID:26113060

  12. Exploring Child Mortality Risks Associated with Diverse Patterns of Maternal Migration in Haiti

    Internal migration is a salient dimension of adulthood in Haiti, particularly among women. Despite the prevalence of migration in Haiti, it remains unknown whether Haitian women’s diverse patterns of migration influence their children’s health and survival. In this paper, we introduce the concept of lateral (i.e., rural-to-rural, urban-to-urban) versus nonlateral (i.e., rural-to-urban, urban-to-rural) migration to describe how some patterns of mothers’ internal migration may be associated with particularly high mortality among children. We use the 2006 Haitian Demographic and Health Survey to estimate a series of discrete-time hazard models among 7,409 rural children and 3,864 urban children. We find that, compared with their peers with nonmigrant mothers, children born to lateral migrants generally experience lower mortality whereas those born to nonlateral migrants generally experience higher mortality. Although there are important distinctions across Haiti’s rural and urban contexts, these associations remain net of socioeconomic factors, suggesting they are not entirely attributable to migrant selection. Considering the timing of maternal migration uncovers even more variation in the child health implications of maternal migration; however, the results counter the standard disruption and adaptation perspective. Although future work is needed to identify the processes underlying the differential risk of child mortality across lateral versus nonlateral migrants, the study demonstrates that looking beyond rural-to-urban migration and considering the timing of maternal migration can provide a fuller, more complex understanding of migration’s association with child health.

  14. Risk factors for asthma: is prevention possible?

    PubMed

    Beasley, Richard; Semprini, Alex; Mitchell, Edwin A

    2015-09-12

    Asthma is one of the most common diseases in the world, resulting in a substantial burden of disease. Although rates of deaths due to asthma worldwide have reduced greatly over the past 25 years, no available therapeutic regimens can cure asthma, and the burden of asthma will continue to be driven by increasing prevalence. The reasons for the increase in asthma prevalence have not been defined, which limits the opportunities to develop targeted primary prevention measures. Although associations are reported between a wide range of risk factors and childhood asthma, substantiation of causality is inherently difficult from observational studies, and few risk factors have been assessed in primary prevention studies. Furthermore, none of the primary prevention intervention strategies that have undergone scrutiny in randomised controlled trials has provided sufficient evidence to lead to widespread implementation in clinical practice. A better understanding of the factors that cause asthma is urgently needed, and this knowledge could be used to develop public health and pharmacological primary prevention measures that are effective in reducing the prevalence of asthma worldwide. To achieve this it will be necessary to think outside the box, not only in terms of risk factors for the causation of asthma, but also the types of novel primary prevention strategies that are developed, and the research methods used to provide the evidence base for their implementation. In the interim, public health efforts should remain focused on measures with the potential to improve lung and general health, such as: reducing tobacco smoking and environmental tobacco smoke exposure; reducing indoor and outdoor air pollution and occupational exposures; reducing childhood obesity and encouraging a diet high in vegetables and fruit; improving feto-maternal health; encouraging breastfeeding; promoting childhood vaccinations; and reducing social inequalities.

    Epidemiological studies suggest that allergy risk is preferentially transmitted through mothers. This can be due to genomic imprinting, where the phenotype effect of an allele depends on its parental origin, or due to maternal effects reflecting the maternal genome's influence on the child during prenatal development. Loss-of-function mutations in the filaggrin gene (FLG) cause skin barrier deficiency and strongly predispose to atopic dermatitis (AD). We investigated the 4 most prevalent European FLG mutations (c.2282del4, p.R501X, p.R2447X, and p.S3247X) in two samples including 759 and 450 AD families. We used the multinomial and maximum-likelihood approach implemented in the PREMIM/EMIM tool to model parent-of-origin effects. Beyond the known role of FLG inheritance in AD (R1meta-analysis = 2.4, P = 1.0 x 10-36), we observed a strong maternal FLG genotype effect that was consistent in both independent family sets and for all 4 mutations analysed. Overall, children of FLG-carrier mothers had a 1.5-fold increased AD risk (S1 = 1.50, Pmeta-analysis = 8.4 x 10-8). Our data point to two independent and additive effects of FLG mutations: i) carrying a mutation and ii) having a mutation carrier mother. The maternal genotype effect was independent of mutation inheritance and can be seen as a non-genetic transmission of a genetic effect. The FLG maternal effect was observed only when mothers had allergic sensitization (elevated allergen-specific IgE antibody plasma levels), suggesting that FLG mutation-induced systemic immune responses in the mother may influence AD risk in the child. Notably, the maternal effect reported here was stronger than most common genetic risk factors for AD recently identified through genome-wide association studies (GWAS). Our study highlights the power of family-based studies in the identification of new etiological mechanisms and reveals, for the first time, a direct influence of the maternal genotype on the offspring's susceptibility to a

    Predation risk is a strong selective force shaping prey morphology, physiology, life history and/or behavior. As a prime stressor, predation risk may even induce trans-generational alterations, called maternal effects. Accordingly, maternal predation risk during offspring production may influence offspring life history and anti-predator behavior. Here, we assessed whether different levels of predation risk, posed by the predatory mite Phytoseiulus persimilis, induce graded maternal effects in its prey, the herbivorous two-spotted spider mite Tetranychus urticae. First, we generated four types of predation risk-stressed spider mite mothers by exposing them to living predators, direct and indirect predator cue combinations or no predator cues, respectively. Then, we investigated the life history (offspring developmental time, sex) and anti-predator response (activity, position on the leaf) of their offspring on leaves with and without direct and indirect predator cues. Maternal stress, no matter of the predation risk level, prolonged the offspring developmental time, as compared to offspring from unstressed mothers. This pattern was more pronounced on leaves with than without predator cues. Offspring from stressed mothers resided more likely on the leaf blade than close to the leaf vein. Offspring sex ratio and activity were not influenced by maternal predation risk but activity was higher on leaves with than without predator cues. We argue that the prolonged developmental time is non-adaptive, yet the changed site preference is adaptive because reducing the encounter likelihood with predators. Our study represents a key example for predation risk-mediated maternal effects on developmental trajectories of offspring. PMID:26923463

    Inconclusive results of the association between genetic polymorphisms involved in folate metabolism and maternal risk for Down syndrome (DS) have been reported. Therefore, this meta-analysis was conducted. We searched electronic databases through May, 2014, for eligible studies. Pooled odds ratios with 95% confidence intervals were used to assess the strength of the association, which was estimated by fixed or random effects models. Heterogeneity among studies was evaluated using Q-test and I2 statistic. Subgroup and sensitivity analyses were also conducted. Publication bias was estimated using Begg's and Egger's tests. A total of 17 case-controls studies were included. There was evidence for an association between the MTRR c.66A>G (rs1801394) polymorphism and maternal risk for DS. In the subgroup analysis, increased maternal risk for DS was found in Caucasians. Additionally, the polymorphic heterozygote MTHFD1 1958GA genotype was associated significantly with maternal risk for DS, when we limit the analysis by studies conformed to Hardy-Weinberg equilibrium. Finally, considering MTR c.2756A>G (rs1805087), TC2 c.776C>G (rs1801198), and CBS c.844ins68, no significant associations have been found, neither in the overall analyses nor in the stratified analyses by ethnicity. In conclusion, our meta-analysis suggested that the MTRR c.66A>G (rs1801394) polymorphism and MTHFD1 c.1958G>A (rs2236225) were associated with increased maternal risk for DS. PMID:25544792

    A matched case-control study of Wilms' tumor investigated parental occupational risk factors. Cases diagnosed in 1970-1983 were identified through a population-based tumor registry and hospital registries in the Greater Philadelphia area. Controls were selected by random digit dialing and were matched to cases on race, birth date (+/- 3 years), and the area code and exchange of the case's telephone number at diagnosis. Parents of 100 matched pairs were interviewed by telephone. Parents of patients and controls were generally similar in demographic characteristics, except that mothers differed in religion. Published schemes were used to group jobs into clusters of similar exposures and to determine exposures from industry and job title. Analyses were done for preconception, pregnancy, and postnatal time periods. More case than control fathers had jobs in a cluster that includes machinists and welders (odds ratios (ORs) = 4.0-5.7, p less than or equal to 0.04). Paternal exposures to lead, silver, tin, and iron (some exposures of this cluster) were associated with Wilms' tumor in some analyses, with moderate odds ratios (ORs = 1.5-3.4). In general, the highest odds ratios were found for the preconception period among the genetic (prezygotic) cases. No maternal job clusters or exposures gave significantly elevated odds ratios. These results support a previous finding that lead is a risk factor, but not radiation, hydrocarbon, or boron exposures.

    Environmental risk factors for osteoporosis were reviewed at a conference held at the National Institute for Environmental Health Sciences 8-9 November 1993. The conference was co-sponsored by the National Institute of Arthritis and Musculoskeletal and Skin Disease and the NIH Office of Research in Women's Health. The objective of the conference was to review what is known about risk factors for osteoporosis and to identify gaps in the present state of knowledge that might be addressed by future research. The conference was divided into two broad themes. The first session focused on current knowledge regarding etiology, risk factors, and approaches to clinical and laboratory diagnosis. This was followed by three sessions in which various environmental pollutants were discussed. Topics selected for review included environmental agents that interfere with bone and calcium metabolism, such as the toxic metals lead, cadmium, aluminum, and fluoride, natural and antiestrogens, calcium, and vitamin D.

    Purpose of review To review the recent literature on risk factors for chronic rhinosinusitis (CRS) with an emphasis on genetic, comorbid diseases and environmental factors associated with CRS. Through identifying potential risk factors for CRS, we glean insights into the underlying pathogenic mechanisms and essential for developing effective therapeutic strategies. Recent findings Recent findings demonstrate that genetics, comorbid medical conditions including airway diseases, gastroesophageal reflux disease, inflammatory and autoimmune diseases and various demographic and environmental factors are associated with having a CRS diagnosis. Limitations of current studies include, variable application of disease definitions, lack of prospective longitudinal studies and a disproportionate focus on tertiary care populations. Summary CRS has a broad spectrum of associations ranging from genetics to comorbid diseases and environmental factors. These predisposing factors provide valuable information for possible designing therapeutic and preventive interventions. However, to better understand whether these associations cause CRS, further studies are needed to independently replicate findings, establish temporal relationships between exposure and disease onset, evaluate the influence of exposure dose on disease severity, and to understand the biological effects of these risk factors in the context of CRS.

    During recent decades much interest has been focused on the possibility of predicting and preventing atopic diseases during pregnancy. The idea of being able to detect a predisposition early and take suitable environmental measures in order to avoid overt allergy is an attractive position. Elevated cord IgE of around 1.0 IU/ml has been proposed as a predictor in western children. However, there remains no information about the effect of maternal lifestyle during pregnancy on these levels. Total IgE levels were therefore determined using Pharmacia CAP system and PRIST, with sensitivities of 0.01 kU/l and 0.25 kU/l, respectively, from serum samples taken from 1138 Japanese pairs of cord blood and pregnant women responding to a questionnaire regarding 17 health practices, intake of 32 food allergens and 5 environmental factors. Of these, 28 (2.5%) pairs of samples were excluded from further analysis because of high contamination of IgA (> 15.4 mg/ml) in cord blood. Median cord blood IgE was 0.286 kU/l and geometric mean IgE was 66.25 kU/l in maternal sera using CAP system; there was no significant correlation between maternal log (IgE) and cord blood IgE. Similar results were obtained from PRIST, whose correlation with CAP system was significant (r = 0.884, p < 0.001 for maternal and r = 0.765, p < 0.001 for cord blood). Multiple logistic analysis demonstrated that avoidance of simultaneous exposure to hens' eggs and cow's milk (relative risk = 1.3, p < 0.05) as well as soy beans (relative risk = 2.8, p < 0.01) should be advised to mothers with positive allergic histories and/or high total IgE (> 400 IU/ml), especially in women aged more than 35 years who are pregnant with a male child. However, maintenance of healthy lifestyles, especially taking proper exercise and sleeping, and avoidance of inhalant allergens during late pregnancy may be a more important strategy for the reduction of cord blood IgE levels.

    We examined the associations of mothers' perception of neighborhood quality and maternal resilience with risk of preterm birth and whether maternal resilience moderated the effect of neighborhood quality perception. We analyzed data from 10,758 women with singleton births who participated in 2010-2012 Los Angeles Mommy and Baby surveys. Multilevel logistic regression models assessed the effects of mothers' perception of neighborhood quality and maternal resilience on preterm birth (yes/no), controlling for potential confounders and economic hardship index, a city-level measure of neighborhood quality. Interaction terms were assessed for moderation. Mothers' perception of neighborhood quality and maternal resilience were each uniquely associated with preterm birth, independent of potential confounders (p-values < 0.05). The risk of preterm birth among mothers who perceived their neighborhood as of poor quality was about 30% greater compared to mothers who perceived their neighborhood as of good quality; the risk was 12% greater among mothers with low resilience compared to those with high resilience. Effects of neighborhood quality were not modified by maternal resilience. The findings suggest that mothers' perception of neighborhood quality and resilience are associated with the risk of preterm birth. Further research should explore whether initiatives aimed at improving neighborhood quality and women's self-esteem may improve birth outcomes. PMID:26274966

    The purpose of this study was to evaluate risk factors for antepartum depressive symptoms that can be assessed in routine obstetric care. We evaluated articles in the Englishlanguage literature from 1980 through 2008. Studies were selected if they evaluated the association between antepartum depressive symptoms and ≥1 risk factors. For each risk factor, 2 blinded, independent reviewers evaluated the overall trend of evidence. In total, 57 studies met eligibility criteria. Maternal anxiety, life stress, history of depression, lack of social support, unintended pregnancy, Medicaid insurance, domestic violence, lower income, lower education, smoking, single status, and poor relationship quality were associated with a greater likelihood of antepartum depressive symptoms in bivariate analyses. Life stress, lack of social support, and domestic violence continued to demonstrate a significant association in multivariate analyses. Our results demonstrate several correlates that are consistently related to an increased risk of depressive symptoms during pregnancy. PMID:20096252

    This article presents findings from a study on women's delivery care-seeking in two regions of Guinea. We explored exposure to interventions promoting birth preparedness and complication readiness among women with recent live births and stillbirths. Using multivariate regression models, we identified factors associated with women's knowledge and practices related to birth preparedness, as well as their use of health facilities during childbirth. We found that women's knowledge about preparations for any birth (normal or complicated) was positively associated with increased preparation for birth, which itself was associated with institutional delivery. Knowledge about complication readiness, obstetric risks, and danger signs was not associated with birth preparation or with institutional delivery. The study findings highlight the importance of focusing on preparation for all births—and not simply obstetric emergencies—in interventions aimed at increasing women's use of skilled maternity care.

    This study examined factors related to birth weight in a maternity hospital in the city of Rio de Janeiro. It is a descriptive, sectional study conducted in the Herculano Pinheiro Maternity Hospital (HMHP) in Rio de Janeiro between December 2008 and February 2009, with postpartum mothers between 20 and 34 years of age. The chi-square test, the Student's t test and the logistical regression model were applied. 14.6% of the infants had low birth weight (less than 2500 g). There was a negative correlation between birth weight and smoking habits of the mother. The pre-pregnancy weight, maternal pre-pregnancy body mass index and number of pre-natal visit variables were positively associated with birth weight. Multiple regression analysis indicated maternal age as being a risk factor for low birth weight. The conclusion reached is that the marital status situation, where this was perceived as an important variable, as well as the number of prenatal visits, which in group analysis showed no statistical significance, deserve further investigation together with other studies.

    A new model of the etiology of sexual harassment, the four-factor model, is presented and compared with several models of sexual harassment including the biological model, the organizational model, the sociocultural model, and the sex role spillover model. A number of risk factors associated with sexually harassing behavior are examined within the framework of the four-factor model of sexual harassment. These include characteristics of the work environment (e.g., sexist attitudes among co-workers, unprofessional work environment, skewed sex ratios in the workplace, knowledge of grievance procedures for sexual harassment incidents) as well as personal characteristics of the subject (e.g., physical attractiveness, job status, sex-role). Subjects were 266 university female faculty, staff, and students who completed the Sexual Experience Questionnaire to assess the experience of sexual harassment and a questionnaire designed to assess the risk factors stated above. Results indicated that the four-factor model is a better predictor of sexual harassment than the alternative models. The risk factors most strongly associated with sexual harassment were an unprofessional environment in the workplace, sexist atmosphere, and lack of knowledge about the organization's formal grievance procedures.

    We examined the link between household chaos (i.e., noise, clutter, disarray, lack of routines) and maternal executive function (i.e., effortful regulation of attention and memory), and whether it varied as a function of socioeconomic risk (i.e., single parenthood, lower mother and father educational attainment, housing situation, and father unemployment). We hypothesized that: 1) higher levels of household chaos would be linked with poorer maternal executive function, even when controlling for other measures of cognitive functioning (e.g., verbal ability), and 2) this link would be strongest in the most socioeconomically distressed or lowest-socioeconomic status households. The diverse sample included 153 mothers from urban and rural areas who completed a questionnaire and a battery of cognitive executive function tasks and a verbal ability task in the laboratory. Results were mixed for Hypothesis 1, and consistent with Hypothesis 2. Two-thirds of the variance overlapped between household chaos and maternal executive function, but only in families with high levels of socioeconomic risk. This pattern was not found for chaos and maternal verbal ability, suggesting that the potentially deleterious effects of household chaos may be specific to maternal executive function. The findings implicate household chaos as a powerful statistical predictor of maternal executive function in socioeconomically distressed contexts. PMID:22563703

    Thyroid disease is a common problem among women of reproductive age but often goes undiagnosed. Maternal thyroid disease has been associated with increased risk of craniosynostosis. We hypothesized that known risk factors for thyroid disease would be associated with risk of craniosynostosis among women not diagnosed with thyroid disease. Analyses included mothers of 1,067 cases and 8,494 population-based controls who were interviewed for the National Birth Defects Prevention Study. We used multivariable logistic regression to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CI). After excluding women with diagnosed thyroid disease, younger maternal age (AOR 0.7, 95% CI 0.6–0.9, for <25 years versus 25–29), black or other race-ethnicity (AOR 0.3, 95% CI 0.2–0.4 and AOR 0.6, 95% CI 0.4–0.8, respectively, relative to non-Hispanic whites), fertility medications or procedures (AOR 1.5, 95% CI 1.2–2.0), and alcohol consumption (AOR 0.8, 95% CI 0.7–0.9) were associated with risk of craniosynostosis, based on confidence intervals that excluded 1.0. These associations with craniosynostosis are consistent with the direction of their association with thyroid dysfunction (i.e., younger age, black race-ethnicity and alcohol consumption are associated with reduced risk and fertility problems are associated with increased risk of thyroid disease). This study thus provides support for the hypothesis that risk factors associated with thyroid dysfunction are also associated with risk of craniosynostosis. Improved understanding of the potential association between maternal thyroid function and craniosynostosis among offspring is important given that craniosynostosis carries significant morbidity and that thyroid disease is under-diagnosed and potentially modifiable.

    To study the associations between maternal consumption of non-staple food in the first trimester and risk of neural tube defects (NTDs) in offspring. Data collected from a hospital-based case-control study conducted between 2006 and 2008 in Shandong/Shanxi provinces including 459 mothers with NTDs-affected births and 459 mothers without NTDs-affected births. Logistic regression models were used to examine the associations between maternal consumption of non-staple food in the first trimester and risk of NTDs in offspring. The effects were evaluated by odds ratio (OR) and 95% confidence intervals (95% CIs) with SAS9.1.3.software. Maternal consumption of milk, fresh fruits and nuts in the first trimester were protective factors for total NTDs. Compared with consumption frequency of ˂1 meal/week, the ORs for milk consumption frequency of 1-2, 3-6, ≥7 meals/week were 0.50 (95% CI: 0.28-0.88), 0.56 (0.32-0.99), and 0.59 (0.38-0.90), respectively; the ORs for fresh fruits consumption frequency of 1-2, 3-6, ≥7 meals/week were 0.29 (95% CI: 0.12-0.72), 0.22 (0.09-0.53), and 0.32 (0.14-0.71), respectively; the ORs for nuts consumption frequency of 1-2, 3-6, ≥7 meals/week were 0.60 (95% CI: 0.38-0.94), 0.49 (0.31-0.79), and 0.63 (0.36-1.08), respectively. Different effects of above factors on NTDs were found for subtypes of anencephaly and spina bifida. Maternal non-staple food consumption of milk, fresh fruits and nuts in the first trimester was associated with reducing NTDs risk in offspring. PMID:25919306

    Growth of ungulate populations is typically most sensitive to survival of neonates, which in turn is influenced by maternal nutritional condition and trade-offs in resource selection and avoidance of predators. We assessed whether resource use, multi-predator risk, maternal nutritional effects, hiding cover, or interactions among these variables best explained variation in daily survival of free-ranging neonatal white-tailed deer (Odocoileus virginianus) during their post-partum period (14 May-31 Aug) in Michigan, USA. We used Cox proportional hazards mixed-effects models to assess survival related to covariates of resource use, composite predation risk of 4 mammalian predators, fawn body mass at birth, winter weather, and vegetation growth phenology. Predation, particularly from coyotes (Canis latrans), was the leading cause of mortality; however, an additive model of non-ideal resource use and maternal nutritional effects explained 71% of the variation in survival. This relationship suggested that dams selected areas where fawns had poor resources, while greater predation in these areas led to additive mortalities beyond those related to resource use alone. Also, maternal nutritional effects suggested that severe winters resulted in dams producing smaller fawns, which decreased their likelihood of survival. Fawn resource use appeared to reflect dam avoidance of lowland forests with poor forage and greater use by wolves (C. lupus), their primary predator. While this strategy led to greater fawn mortality, particularly by coyotes, it likely promoted the life-long reproductive success of dams because many reached late-age (>10 years old) and could have produced multiple generations of fawns. Studies often link resource selection and survival of ungulates, but our results suggested that multiple factors can mediate that relationship, including multi-predator risk. We emphasize the importance of identifying interactions among biological and environmental factors when

    The research aim was 1) to determine the incidence of maternal mortality in a rural health center area in Sirur, Maharashtra state, India; 2) to determine the relative risk; and 3) to make suggestions about reducing maternal mortality. The data on deliveries was obtained between 1981 and 1984. Medical care at the Rural Training Center was supervised by the Department of Preventive and Social Medicine, the B.J. Medical College in Pune. Deliveries numbered 5994 singleton births over the four years; 5919 births were live births. 15 mothers died: 14 after delivery and 1 predelivery. The maternal mortality rate was 2.5/1000 live births. The maternal causes of death included 9 direct obstetric causes, 3 from postpartum hemorrhage of anemic women, and 3 from puerperal sepsis of anemic women with prolonged labor. 2 deaths were due to eclampsia, and 1 death was unexplained. There were 5 (33.3%) maternal deaths due to indirect causes (3 from hepatitis and 2 from thrombosis). One woman died of undetermined causes. Maternal jaundice during pregnancy was associated with the highest relative risk of maternal death: 106.4. Other relative risk factors were edema, anemia, and prolonged labor. Attributable risk was highest for anemia, followed by jaundice, edema, and maternal age of over 30 years. Maternal mortality at 30 years and older was 3.9/1000 live births. Teenage maternal mortality was 3.3/1000. Maternal mortality among women 20-29 years old was lowest at 2.1/1000. Maternal mortality for women with a parity of 5 or higher was 3.6/1000. Prima gravida women had a maternal mortality rate of 2.9/1000. Parities between 1 and 4 had a maternal mortality rate of 2.3/1000. The lowest maternal mortality was at parity of 3. Only 1 woman who died had received more than 3 prenatal visits. 11 out of 13 women medically examined prenatally were identified with the following risk factors: jaundice, edema, anemia, young or old maternal age, parity, or poor obstetric history.

    Objective: ADHD and asthma are prevalent conditions in childhood, with complex pathophysiology involving genetic-environmental interplay. The study objective is to examine the prevalence of asthma in our ADHD population and explore factors that may increase the risk of developing asthma in children with ADHD. Methods: We retrospectively analyzed the presence of maternal stress during pregnancy and history of asthma in 201 children diagnosed with ADHD. Results: Chi-square analysis indicated significant higher presence of asthma in our ADHD sample compared to Quebec children, χ2(1, N = 201) = 15.37, P<0.001. Only prematurity and stress during pregnancy significantly predicted asthma in a logistic regression model, χ2(2)=23.70, P<0.001, with odds ratios of 10.6 (95% CI: 2.8–39.5) and 3.2 (95% CI: 1.4–7.3), respectively. Conclusion: Children with ADHD have a higher prevalence of asthma than the general Quebec pediatric population. Children with ADHD born prematurely and/or those whose mothers experienced stress during pregnancy have a significantly increased risk of developing asthma. The study highlights the importance of potentially offering social and psychological support to mothers who experienced stress during pregnancy and/or are at risk of delivering prematurely.

    Mice deficient in corticotropin releasing factor receptor 2 (CRF2) (C57BL/6J:129Sv background) exhibit impaired maternal defense (protection of offspring) and are more reactive to stressors than wild-type mice. To further understand CRF2’s role in maternal behavior, we crossed the knockout mice with a line bred for high maternal defense that also has elevated maternal care relative to inbred lines. Maternal care was normal in knockout mice (relative to wild-type). Maternal defense was impaired as previously observed. Exposure to a mild stressor (15 min restraint) did not trigger deficits in maternal defense in either genotype as determined by a two-way repeated measures ANOVA analysis. However, when examining difference scores between unrestrained and restrained conditions, knockout mice exhibited significant decreases in maternal defense with stress, suggesting knockouts are more susceptible to a mild stressor’s effects. To gain possible insights into brain activity differences between WT and KO mice, we examined c-Fos expression in association with stress. Unrestrained KO mice exhibited significantly lower c-Fos levels relative to unrestrained WT mice in 9 regions, including lateral septum and periaqueductal gray. For WT mice, restraint stress triggered c-Fos activity increases in 3 regions while for KO mice, restraint stress triggered c-Fos increases in 16 regions. Taken together, our results suggest both altered behavioral and c-Fos responses to stress in lactating CRF2 KO mice. PMID:18817761

    Maternal obesity and overnutrition during pregnancy and lactation can program an increased risk of obesity in offspring. In this context, improving maternal metabolism may help reduce the intergenerational transmission of obesity. Here we show that, in Sprague-Dawley rats, selectively altering obese maternal gut microbial composition with prebiotic treatment reduces maternal energy intake, decreases gestational weight gain, and prevents increased adiposity in dams and their offspring. Maternal serum metabolomics analysis, along with satiety hormone and gut microbiota analysis, identified maternal metabolic signatures that could be implicated in programming offspring obesity risk and highlighted the potential influence of maternal gut microbiota on maternal and offspring metabolism. In particular, the metabolomic signature of insulin resistance in obese rats normalized when dams consumed the prebiotic. In summary, prebiotic intake during pregnancy and lactation improves maternal metabolism in diet-induced obese rats in a manner that attenuates the detrimental nutritional programming of offspring associated with maternal obesity. Overall, these findings contribute to our understanding of the maternal mechanisms influencing the developmental programming of offspring obesity and provide compelling pre-clinical evidence for a potential strategy to improve maternal and offspring metabolic outcomes in human pregnancy.

  20. The genetics of folate metabolism and maternal risk of birth of a child with Down syndrome and associated congenital heart defects

    2015-01-01

    Almost 15 years ago it was hypothesized that polymorphisms of genes encoding enzymes involved in folate metabolism could lead to aberrant methylation of peri-centromeric regions of chromosome 21, favoring its abnormal segregation during maternal meiosis. Subsequently, more than 50 small case-control studies investigated whether or not maternal polymorphisms of folate pathway genes could be risk factors for the birth of a child with Down syndrome (DS), yielding conflicting and inconclusive results. However, recent meta-analyses of those studies suggest that at least three of those polymorphisms, namely MTHFR 677C>T, MTRR 66A>G, and RFC1 80G>A, are likely to act as maternal risk factors for the birth of a child with trisomy 21, revealing also complex gene-nutrient interactions. A large-cohort study also revealed that lack of maternal folic acid supplementation at peri-conception resulted in increased risk for a DS birth due to errors occurred at maternal meiosis II in the aging oocyte, and it was shown that the methylation status of chromosome 21 peri-centromeric regions could favor recombination errors during meiosis leading to its malsegregation. In this regard, two recent case-control studies revealed association of maternal polymorphisms or haplotypes of the DNMT3B gene, coding for an enzyme required for the regulation of DNA methylation at centromeric and peri-centromeric regions of human chromosomes, with risk of having a birth with DS. Furthermore, congenital heart defects (CHD) are found in almost a half of DS births, and increasing evidence points to a possible contribution of lack of folic acid supplementation at peri-conception, maternal polymorphisms of folate pathway genes, and resulting epigenetic modifications of several genes, at the basis of their occurrence. This review summarizes available case-control studies and literature meta-analyses in order to provide a critical and up to date overview of what we currently know in this field. PMID:26161087

    Objective To determine the risk factors for neonatal encephalopathy among term infants in a developing country. Design Unmatched case-control study. Setting Principal maternity hospital of Kathmandu, Nepal. Subjects All 131 infants with neonatal encephalopathy from a population of 21 609 infants born over an 18 month period, and 635 unmatched infants systematically recruited over 12 months. Main outcome measures Adjusted odds ratio estimates for antepartum and intrapartum risk factors. Results The prevalence of neonatal encephalopathy was 6.1 per 1000 live births of which 63% were infants with moderate or severe encephalopathy. The risk of death from neonatal encephalopathy was 31%. The risk of neonatal encephalopathy increased with increasing maternal age and decreasing maternal height. Antepartum risk factors included primiparity (odds ratio 2.0) and non-attendance for antenatal care (2.1). Multiple births were at greatly increased risk (22). Intrapartum risk factors included non-cephalic presentation (3.4), prolonged rupture of membranes (3.8), and various other complications. Particulate meconium was strongly associated with encephalopathy (18). Induction of labour with oxytocin was associated with encephalopathy in 12 of 41 deliveries (5.7). Overall, 78 affected infants (60%) compared with 36 controls (6%) either had evidence of intrapartum compromise or were born after an intrapartum difficulty likely to result in fetal compromise. A concentration of maternal haemoglobin of less than 8.0 g/dl in the puerperium was significantly associated with encephalopathy (2.5) as was a maternal thyroid stimulating hormone concentration greater than 5 mIU/l (2.1). Conclusions Intrapartum risk factors remain important for neonatal encephalopathy in developing countries. There is some evidence of a protective effect from antenatal care. The use of oxytocin in low income countries where intrapartum monitoring is suboptimal presents a major risk to the fetus. More work is

    Purpose This study aimed to examine extended postoperative ileus and its risk factors in patients who have undergone abdominal surgery, and discuss the techniques of prevention and management thereof the light of related risk factors connected with our study. Methods This prospective study involved 103 patients who had undergone abdominal surgery. The effects of age, gender, diagnosis, surgical operation conducted, excessive small intestine manipulation, opioid analgesic usage time, and systemic inflammation on the time required for the restoration of intestinal motility were investigated. The parameters were investigated prospectively. Results Regarding the factors that affected the restoration of gastrointestinal motility, resection operation type, longer operation period, longer opioid analgesics use period, longer nasogastric catheter use period, and the presence of systemic inflammation were shown to retard bowel motility for 3 days or more. Conclusion Our study confirmed that unnecessary analgesics use in patients with pain tolerance with non-steroid anti-inflammatory drugs, excessive small bowel manipulation, prolonged nasogastric catheter use have a direct negative effect on gastrointestinal motility. Considering that an exact treatment for postoperative ileus has not yet been established, and in light of the risk factors mentioned above, we regard that prevention of postoperative ileus is the most effective way of coping with intestinal dysmotility.

    The present study sought to examine associations between maternal psychopathology, parental monitoring, and adolescent sexual activity among adolescents in mental health treatment. Seven hundred ninety mother-adolescent dyads recruited from adolescent mental health treatment settings completed audio computer-assisted structured interview assessments examining parent psychiatric symptoms, parental monitoring, and adolescent sexual risk behavior. Path analysis was used to examine the associations between variables of interest. Maternal caregivers who reported more mental health symptoms were more likely to have adolescents who reported recent sex and this relationship was mediated by less parental monitoring. These findings suggest that maternal caregivers with mental health symptoms may need specific interventions that provide assistance and support in monitoring their teens in order to reduce sexual risk taking among adolescents in mental health treatment.

    The authors used data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,364) to examine maternal work hour status and parenting (sensitivity and learning opportunities) from infancy through middle childhood. Work hour status was conceptualized as nonemployment, part time, and full time. Adjusting for covariates, mothers employed part time had higher sensitivity scores and higher provision of child learning opportunity scores than did mothers who were not employed, and these differences characterized families during early childhood rather than middle childhood. Mothers’ provision of child learning opportunities was greater when employed full time (vs. part time) during early childhood. In addition to child age, mothers’ ethnic minority status and partner status moderated the association between maternal work hour status and mothers’ parenting. In general, the findings supported ideas forwarded by role expansionist theory. PMID:25530631

    Owing to recent advancements in imaging techniques and biomarker research, the natural history of Alzheimer's disease (AD) has become clear from the very first preclinical stage. According to the study, more than 20 years before the onset of AD, Aβ starts to accumulate in the brain. This induces neurofibrillary tangle formation in the cerebral isocortex, leading to cognitive decline. If this process is suppressed, disease activity can be controlled. However, at this point, the best and most realistic way to deal with AD is to target the environmental factors that have been identified as risk factors by epidemiological studies. PMID:27395468

    Background Prenatal factors may contribute to the development of peanut allergy. We evaluated the risk of childhood peanut allergy in association with pregnancy exposure to Rh immune globulin, folic acid and ingestion of peanut-containing foods. Methods We conducted a web-based case-control survey using the Anaphylaxis Canada Registry, a pre-existing database of persons with a history of anaphylaxis. A total of 1300 case children with reported peanut allergy were compared to 113 control children with shellfish allergy. All were evaluated for maternal exposure in pregnancy to Rh immune globulin and folic acid tablet supplements, as well as maternal avoidance of dietary peanut intake in pregnancy. Results Receipt of Rh immune globulin in pregnancy was not associated with a higher risk of peanut allergy (odds ratio [OR] 0.86, 95% confidence interval [CI] 0.51 to 1.45), nor was initiation of folic acid tablet supplements before or after conception (OR 0.53, 95% CI 0.19 to 1.48). Complete avoidance of peanut-containing products in pregnancy was associated with a non-significantly lower risk of peanut allergy (OR 0.53, 95% CI 0.27 to 1.03). Conclusion The risk of childhood peanut allergy was not modified by the following common maternal exposures in pregnancy: Rh immune globulin, folic acid or peanut-containing foods. Clinical implications Rh immune globulin, folic acid supplement use and peanut avoidance in pregnancy have yet to be proven to modulate the risk of childhood anaphylaxis to peanuts. Capsule Summary Identification of prenatal factors that contribute to peanut allergy might allow for prevention of this life-threatening condition.

    Maternal smoking during early pregnancy is associated with a reduced risk for preeclampsia even after smoking cessation during pregnancy. Although the pathophysiology of preeclampsia has not been established, placental growth factor (PlGF) is believed to be a key factor. The aim of this study was to assess the effect of maternal smoking on the PlGF expression in invasive trophoblasts at early gestation. We collected villous tissues from women requesting surgical termination due to non-medical reasons at 7-8 weeks of gestation. The maternal smoking status was evaluated by measuring the serum cotinine level and patients were divided into two groups: active smokers and non-smokers. After separating invasive trophoblasts from villous tissues cultured initially under 2% O2 for 24 hours, the separated invasive trophoblasts were cultured under 2% or 8% O2 for 48 hours. The expression levels of the PlGF gene in villous tissue specimens and in invasive trophoblasts cultured after the conditions were quantified using qRT-PCR. The levels of PlGF protein in the medium were quantified using an ELISA. The gene expression level of PlGF in the villi in the active-smokers was significantly higher than that of the non-smokers. In comparison of the invasive trophoblasts under normoxia and oxygenated conditions, the ratio of PlGF gene expression and protein expression under oxygenation (2% O2+8% O2 / 2% O2+2% O2) in the active-smokers were both significantly higher than in the non-smokers. Maternal smoking history appears to stimulate PlGF expression in invasive trophoblasts under oxygenated conditions. This may be one of several causes leading to the protective effect of maternal smoking on preeclampsia. PMID:26214510

    The association between maternal smoking during pregnancy and autism spectrum disorder (ASD) risk in offspring has been investigated in several studies, but the evidence is not conclusive. We, therefore, conducted this meta-analysis to explore whether an association exists between maternal smoking during pregnancy and ASD risk in offspring. We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies of maternal smoking during pregnancy and ASD risk in offspring up to 10 June 2015. The random-effects model was used to combine results from individual studies. 15 observational studies (6 cohort studies and 9 case-control studies), with 17,890 ASD cases and 1,810,258 participants were included for analysis. The pooled odds ratio (OR) was 1.02 (95% confidence interval (CI): 0.93–1.13) comparing mothers who smoked during pregnancy with those who did not. Subgroup and sensitivity analysis suggested the overall result of this analysis was robust. Results from this meta-analysis indicate that maternal smoking during pregnancy is not associated with ASD risk in offspring. Further well-designed cohort studies are needed to confirm the present findings. PMID:26343689

    Metabolome analysis of the serum from pregnant patients aimed at detection of low-molecular-weight biomarkers of gestation process disorders indicated a relationship between the metabolic profile of maternal serum and risk of gestosis. In women with pre-eclampsia or preterm delivery, analysis of serum purine metabolites revealed changes in the metabolite concentrations, associated with pregnancy complications. PMID:24288739

    Despite the wide availability of antiretroviral drugs, more than 250,000 infants are vertically infected with HIV-1 annually, emphasizing the need for additional interventions to eliminate pediatric HIV-1 infections. Here, we aimed to define humoral immune correlates of risk of mother-to-child transmission (MTCT) of HIV-1, including responses associated with protection in the RV144 vaccine trial. Eighty-three untreated, HIV-1–transmitting mothers and 165 propensity score–matched nontransmitting mothers were selected from the Women and Infants Transmission Study (WITS) of US nonbreastfeeding, HIV-1–infected mothers. In a multivariable logistic regression model, the magnitude of the maternal IgG responses specific for the third variable loop (V3) of the HIV-1 envelope was predictive of a reduced risk of MTCT. Neutralizing Ab responses against easy-to-neutralize (tier 1) HIV-1 strains also predicted a reduced risk of peripartum transmission in secondary analyses. Moreover, recombinant maternal V3–specific IgG mAbs mediated neutralization of autologous HIV-1 isolates. Thus, common V3-specific Ab responses in maternal plasma predicted a reduced risk of MTCT and mediated autologous virus neutralization, suggesting that boosting these maternal Ab responses may further reduce HIV-1 MTCT.

    Past research has identified parental depression and family-of-origin maltreatment as precursors to adolescent depression and antisocial behavior. Caregiving experiences have also been identified as a factor that may ameliorate or accentuate adolescent psychopathology trajectories. Using the unique attributes of two geographically diverse, yet complementary longitudinal research designs, the present study examined the role of maternal caregiver involvement as a factor that promotes resilience-based trajectories related to depressive symptom and antisocial behaviors among adolescent girls. The first sample comprises a group of US-based adolescent girls in foster care (n = 100; mean age = 11.50 years), all of whom have had a history of childhood maltreatment and removal from the home of their biological parent(s). The second sample comprises a group of UK-based adolescent girls at high familial risk for depression (n = 145; mean age = 11.70 years), with all girls having a biological mother who has experienced recurrent depression. Study analyses examined the role of maternal caregiving on girls’ trajectories of depression and antisocial behavior, while controlling for levels of co-occurring psychopathology at each time point across the study period. Results suggest increasing trajectories of depressive symptoms, controlling for antisocial behavior, for girls at familial risk for depression, but decreasing trajectories for girls in foster care. A similar pattern of results was noted for antisocial behavior trajectories, controlling for depressive symptoms. Maternal caregiver involvement was differentially related to intercept and slope parameters in both samples. Results are discussed with respect to the identification of family level promotive factors aimed at reducing negative developmental trajectories among high-risk youth. PMID:25422973

    Background The parent-child relationship may be an important factor in the development of adolescent depressive and anxious symptoms. In adults, depressive symptoms relate to increased amygdala and attenuated prefrontal activation to maternal criticism. The current pilot study examined how depressive and anxiety symptoms in a high-risk adolescent population relate to neural responses to maternal feedback. Given previous research relating oxytocin to maternal behavior, we conducted exploratory analyses using oxytocin receptor (OXTR) genotype. Methods Eighteen females (ages 12–16) listened to maternal praise, neutral, and critical statements during functional magnetic resonance imaging. Participants completed the Mood and Feelings Questionnaire and the Screen for Child Anxiety Related Emotional Disorders. The OXTR single nucleotide polymorphism, rs53576, was genotyped. Linear mixed models were used to identify symptom or allele (GG, AA/AG) by condition (critical, neutral, praise) interaction effects on brain activation. Results Greater symptoms related to greater right amygdala activation for criticism and reduced activation to praise. For left amygdala, greater symptoms related to reduced activation to both conditions. Anxiety symptoms related to differences in superior medial PFC activation patterns. Parental OXTR AA/AG allele related to reduced activation to criticism and greater activation to praise within the right amygdala. Conclusions Results support a relationship between anxiety and depressive symptoms and prefrontal-amygdala responses to maternal feedback. The lateralization of amygdala findings suggests separate neural targets for interventions reducing reactivity to negative feedback or increasing salience of positive feedback. Exploratory analyses suggest that parents' OXTR genetic profile influences parent-child interactions and related adolescent brain responses. PMID:27158587

    OBJECTIVES: The objective of this study was to identify neonatal and maternal characteristics that may be associated with elevated neonatal gentamicin trough concentrations despite application of a previously published gentamicin dosage strategy. METHODS: Retrospective cohort study of all neonates admitted to University of Vermont Medical Center (562-bed academic teaching hospital, Burlington, VT) receiving gentamicin between June 1, 2009, and August 31, 2013. A total of 205 neonates were included, with 41 cases and 164 controls. RESULTS: Postmenstrual age (PMA, gestational age plus chronological age) and small-for–gestational age (SGA) status were independently associated with elevated neonatal gentamicin trough concentrations. No maternal risk factor evaluated remained significantly associated in the multivariate analysis. CONCLUSIONS: The probability of an elevated gentamicin trough concentration increases with lower PMA and is further accentuated in neonates with SGA status. In contrast, the presence of maternal risk factors did not increase the likelihood of elevated gentamicin trough concentrations. Neonates with lower PMA and SGA status may require an individualized dosage and monitoring strategy. PMID:27199620

    Recent studies in rodents suggest that maternal immune activation (MIA) by viral infection is associated with schizophrenia and autism in offspring. Although maternal IL-6 is though t to be a possible mediator relating MIA induced these neuropsychiatric disorders, the mechanism remains to be elucidated. Previously, we reported that the maternal leukemia inhibitory factor (LIF)-placental ACTH-fetal LIF signaling relay pathway (maternal-fetal LIF signal relay) promotes neurogenesis of fetal cerebrum in rats. Here we report that the maternal-fetal LIF signal relay in mice is suppressed by injection of polyriboinosinic-polyribocytidylic acid into dams, which induces MIA at 12.5 days post-coitum. Maternal IL-6 levels and gene expression of placental suppressor of cytokine signaling 3 (Socs3) increased according to the severity of MIA and gene expression of placental Socs3 correlated with maternal IL-6 levels. Furthermore, we show that MIA causes reduction of LIF level in the fetal cerebrospinal fluid, resulting in the decreased neurogenesis in the cerebrum. These findings suggest that maternal IL-6 interferes the maternal-fetal LIF signal relay by inducing SOCS3 in the placenta and leads to decreased neurogenesis. PMID:26043040

    This Swedish nationwide cohort study aims to examine the role of maternal characteristics (maternal age, education, smoking, BMI, diabetes, and preeclampsia) and multiple intrauterine growth measures on the risk of childhood lymphomas. A total of 3 444 136 singleton live births registered in the Swedish Medical Birth Register were analyzed, among whom there were 515 incident non-Hodgkin lymphoma (NHL) cases and 169 Hodgkin lymphoma (HL) cases aged 0-14 years at diagnosis (1973-2007) identified through linkage with the Swedish Cancer Register. Proportional hazards models were used to estimate the hazard ratio (HR) and 95% confidence intervals (95% CI) of NHL and HL. Male sex (HR=2.00, 95% CI: 1.66-2.41), older maternal age (HR=1.03, 95% CI: 1.00-1.06, per 1-year increase), and large for gestational age compared with appropriate for gestational age (AGA) birth weight (HR=1.83, 95% CI: 1.20-2.79) were correlated with the risk of NHL; of note, in subanalysis by sex, the latter association was confined to girls (HR=3.37, 95% CI: 1.90-5.97, Pinteraction by sex=0.008). The risk of childhood HL overall was more evident among boys (HR=2.03, 95% CI: 1.46-2.81), whereas indices of accelerated fetal growth were not convincingly associated with the risk of HL. Apart from the established association with sex, the findings point to accelerated intrauterine growth as a risk factor for childhood NHL that may differ by sex. Given the rarity of this condition at birth, however, further studies with more elaborate indices are needed to conclude on its association with rare diseases such as HL. PMID:25569452

    OBJECTIVE To assess trends of tubal factor infertility and to evaluate risk of miscarriage and delivery of preterm or low birth weight (LBW) neonates among women with tubal factor infertility using assisted reproductive technology (ART). METHODS We assessed trends of tubal factor infertility among all fresh and frozen, donor, and nondonor ART cycles performed annually in the United States between 2000 and 2010 (N=1,418,774) using the National ART Surveillance System. The data set was then limited to fresh, nondonor in vitro fertilization cycles resulting in pregnancy to compare perinatal outcomes for cycles associated with tubal compared with male factor infertility. We performed bivariate and multivariable analyses controlling for maternal characteristics and calculated adjusted risk ratios (RRs) and 95% confidence intervals (CI). RESULTS The percentage of ART cycles associated with tubal factor infertility diagnoses decreased from 2000 to 2010 (26.02–14.81%). Compared with male factor infertility, tubal factor portended an increased risk of miscarriage (14.0% compared with 12.7%, adjusted RR 1.08, 95% CI 1.04–1.12); risk was increased for both early and late miscarriage. Singleton neonates born to women with tubal factor infertility had an increased risk of pre-term birth (15.8% compared with 11.6%, adjusted RR 1.27, 95% CI 1.20–1.34) and LBW (10.9% compared with 8.5%, adjusted RR 1.28, 95% CI 1.20–1.36). Significant increases in risk persisted for early and late preterm delivery and very low and moderately LBW delivery. A significantly elevated risk was also detected for twin, but not triplet, pregnancies. CONCLUSION Tubal factor infertility, which is decreasing in prevalence in the United States, is associated with an increased risk of miscarriage, preterm birth, and LBW delivery as compared with couples with male factor infertility using ART.

    This study analyzes the relationships between maternal risk factors present at the time of daughters' births-namely, young mother, high parity, and short preceding birth interval-and their subsequent adult developmental, reproductive, and socioeconomic outcomes. Pseudo-cohorts are constructed using female respondent data from 189 cross-sectional rounds of Demographic and Health Surveys conducted in 50 developing countries between 1986 and 2013. Generalized linear models are estimated to test the relationships and calculate cohort-level outcome proportions with the systematic elimination of the three maternal risk factors. The simulation exercise for the full sample of 2,546 pseudo-cohorts shows that the combined elimination of risk exposures is associated with lower mean proportions of adult daughters experiencing child mortality, having a small infant at birth, and having a low body mass index. Among sub-Saharan African cohorts, the estimated changes are larger, particularly for years of schooling. The pseudo-cohort approach can enable longitudinal testing of life course hypotheses using large-scale, standardized, repeated cross-sectional data and with considerable resource efficiency.

    BACKGROUND This study examined the association between maternal smoking and alcohol use (including binge drinking) during the periconceptional period (i.e., 2 months before through 2 months after conception) and the risk of orofacial clefts, NTDs, and conotruncal heart defects in offspring. METHODS Data were drawn from a population-based case-control study of fetuses and live-born infants among a cohort of California births between July 1999 and June 2003. The 1,355 cases comprised of 701 orofacial clefts, 337 NTDs, and 323 conotruncal heart defects. Information on smoking and alcohol consumption was obtained via telephone interviews with mothers of 1,355 (80% of eligibles) cases and 700 (77% of eligibles) nonmalformed, live-born controls. RESULTS Maternal smoking of five cigarettes or less per day was associated with reduced risks of NTDs (OR 0.7; 95% CI: 0.3, 1.4), whereas the risk associated with higher cigarette consumption was lower for conotruncal heart defects (OR 0.5; 95% CI: 0.2, 1.2). Maternal intake of alcohol less than 1 day per week was associated with a 1.6- to 2.1-fold higher risk of NTDs (95% CI: 0.9, 2.6), d-transposition of the great arteries (95% CI: 1.1, 3.2), and multiple cleft lip with or without cleft palate (CLP) (95% CI: 0.8, 4.5). Risks associated with more frequent alcohol intake were 2.1 for NTDs (95% CI: 1.1, 4.0) and 2.6 for multiple CLP (95% CI: 1.1, 6.1). CONCLUSIONS This study observed that maternal alcohol intake increased the risk for d-transposition of the great arteries, NTDs, and multiple CLP in infants. By contrast, smoking was associated with a lower risk of NTDs and conotruncal heart defects. PMID:18481814

    Single-gene analyses indicate that maternal genes associated with metabolic conditions (e.g., obesity) may influence the risk of neural tube defects (NTDs). However, to our knowledge, there have been no assessments of maternal-fetal metabolic gene-gene interactions and NTDs. We investigated 23 single nucleotide polymorphisms among 7 maternal metabolic genes (ADRB3, ENPP1, FTO, LEP, PPARG, PPARGC1A, and TCF7L2) and 2 fetal metabolic genes (SLC2A2 and UCP2). Samples were obtained from 737 NTD case-parent triads included in the National Birth Defects Prevention Study for birth years 1999-2007. We used a 2-step approach to evaluate maternal-fetal gene-gene interactions. First, a case-only approach was applied to screen all potential maternal and fetal interactions (n = 76), as this design provides greater power in the assessment of gene-gene interactions compared to other approaches. Specifically, ordinal logistic regression was used to calculate the odds ratio (OR) and 95% confidence interval (CI) for each maternal-fetal gene-gene interaction, assuming a log-additive model of inheritance. Due to the number of comparisons, we calculated a corrected p-value (q-value) using the false discovery rate. Second, we confirmed all statistically significant interactions (q < 0.05) using a log-linear approach among case-parent triads. In step 1, there were 5 maternal-fetal gene-gene interactions with q < 0.05. The "top hit" was an interaction between maternal ENPP1 rs1044498 and fetal SLC2A2 rs6785233 (interaction OR = 3.65, 95% CI: 2.32-5.74, p = 2.09×10(-8), q=0.001), which was confirmed in step 2 (p = 0.00004). Our findings suggest that maternal metabolic genes associated with hyperglycemia and insulin resistance and fetal metabolic genes involved in glucose homeostasis may interact to increase the risk of NTDs.

    In addition to the revascularization and glycemic management interventions assigned at random, the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) design includes the uniform control of major coronary artery disease risk factors, including dyslipidemia, hypertension, smoking, central obesity, and sedentary lifestyle. Target levels for risk factors were adjusted throughout the trial to comply with changes in recommended clinical practice guidelines. At present, the goals are low-density lipoprotein cholesterol <2.59 mmol/L (<100 mg/dL) with an optional goal of <1.81 mmol/L (<70 mg/dL); plasma triglyceride level <1.70 mmol/L (<150 mg/dL); blood pressure level <130 mm Hg systolic and <80 mm Hg diastolic; and smoking cessation treatment for all active smokers. Algorithms were developed for the pharmacologic management of dyslipidemia and hypertension. Dietary prescriptions for the management of glycemia, plasma lipid profiles, and blood pressure levels were adapted from existing clinical practice guidelines. Patients with a body mass index >25 were prescribed moderate caloric restriction; after the trial was under way, a lifestyle weight-management program was instituted. All patients were formally prescribed both endurance and resistance/flexibility exercises, individually adapted to their level of disability and fitness. Pedometers were distributed as a biofeedback strategy. Strategies to achieve the goals for risk factors were designed by BARI 2D working groups (lipid, cardiovascular and hypertension, and nonpharmacologic intervention) and the ongoing implementation of the strategies is monitored by lipid, hypertension, and lifestyle intervention management centers.

    To study maternal smoking during pregnancy and the risk of congenital urinary tract anomalies, we interviewed mothers of 118 affected infants born to residents of western Washington State during 1990 and 1991 and mothers of 369 control infants randomly selected from those without birth defects delivered during those years in five hospitals in King County, Washington. Maternal smoking was associated with an increased risk of congenital urinary tract anomalies in offspring (adjusted odds ratio [OR] = 2.3; 95% confidence interval [CI] = 1.2, 4.5). This risk was higher among light smokers (1-1000 cigarettes during the pregnancy) (OR = 3.7; 95% CI = 1.7, 8.6) than among heavy smokers (OR = 1.4; 95% CI = 0.6, 3.3).

    OBJECTIVE: To examine data on Medicaid and self-pay/charity maternity cases to address four questions: (1) Did safety-net hospitals' share of Medicaid patients decline while their shares of self-pay/charity-care patients increased from 1991 to 1994? (2) Did Medicaid patients' propensity to use safety-net hospitals decline during 1991-94? (3) Did self-pay/charity patients' propensity to use safety-net hospitals increase during 1991-94? (4) Did the change in Medicaid patients' use of safety-net hospitals differ for low- and high-risk patients? STUDY DESIGN: We use hospital discharge data to estimate logistic regression models of hospital choice for low-risk and high-risk Medicaid and self-pay/charity maternity patients for 25 metropolitan statistical areas (MSAs) in five states for the years 1991 and 1994. We define low-risk patients as discharges without comorbidities and high-risk patients as discharges with comorbidities that may substantially increase hospital costs, length of stay, or morbidity. The five states are California, Florida, Massachusetts, New Jersey, and New York. The MSAs in the analysis are those with at least one safety-net hospital and a population of 500,000 or more. This study also uses data from the 1990 Census and AHA Annual Survey of Hospitals. The regression analysis estimates the change between 1991 and 1994 in the relative odds of a Medicaid or self-pay/charity patient using a safety-net hospital. We explore whether this change in the relative odds is related to the risk status of the patient. PRINCIPAL FINDINGS: The findings suggest that competition for Medicaid patients increased from 1991 to 1994. Over time, safety-net hospitals lost low-risk maternity Medicaid patients while services to high-risk maternity Medicaid patients and self-pay/charity maternity patients remained concentrated in safety-net hospitals. IMPLICATIONS FOR POLICY: Safety-net hospitals use Medicaid patient revenues and public subsidies that are based on Medicaid

    The current study investigated the influential role of infant avoidance on links between maternal caregiving behavior and trajectories at risk for psychopathology. A sample of 153 children, selected for temperamental reactivity to novelty, was followed from infancy through early childhood. At 9 months, infant avoidance of fear-eliciting stimuli in the laboratory and maternal sensitivity at home were assessed. At 36 months, maternal gentle discipline was assessed at home. Children were repeatedly observed in the lab with an unfamiliar peer across early childhood. A latent class growth analysis yielded three longitudinal risk trajectories of social reticence behavior: a high-stable trajectory, a high-decreasing trajectory, and a low-increasing trajectory. For infants displaying greater avoidance, 9-month maternal sensitivity and 36-month maternal gentle discipline were both positively associated with membership in the high-stable social reticence trajectory, compared to the high-decreasing social reticence trajectory. For infants displaying lower avoidance, maternal sensitivity was positively associated with membership in the high-decreasing social reticence trajectory, compared to the low-increasing trajectory. Maternal sensitivity was positively associated with the high-stable social reticence trajectory when maternal gentle discipline was lower. These results illustrate the complex interplay of infant and maternal behavior in early childhood trajectories at risk for emerging psychopathology. PMID:26439068

    Background. The epidemiology of congenital malaria was investigated in a hospital-based malaria surveillance study in Papua, Indonesia. Methods. From April 2005 to January 2010, 4878 delivering women and their newborns underwent prospective clinical review and malaria screening by peripheral blood microscopy. Findings. Congenital malaria occurred in 8 per 1000 (38/4884) live births, with Plasmodium falciparum accounting for 76.3% (29) and P. vivax for 15.8% (6) of infections. Maternal malaria at delivery (adjusted odds ratio [AOR], 9.5; 95% confidence interval [CI], 4.2–21.5; P < .001), age ≤ 16 years (AOR, 4; 95% CI, 1.4–12.1; P = .011), and prior malaria during pregnancy (AOR, 2.2; 95% CI, 1.1–4.4, P = .022) were independent risk factors for vertical transmission. Of 29 mothers and neonates with contemporaneous peripheral parasitemia, 17% (5) had discordant parasite species, suggesting possible antenatal malaria transmission. Newborns with malaria were at significantly greater risk of low birth weight (AOR, 2.8; 95% CI, 1.2–6.6; P = .002). Following introduction of dihydroartemisinin-piperaquine for uncomplicated malaria in the second and third trimesters of pregnancy, congenital malaria incidence fell from 3.2% to 0.2% (odds ratio, 0.07; 95% CI, .03–.15; P < .001). Conclusions. Congenital malaria is an important cause of neonatal morbidity in this region co-endemic for P. falciparum and P. vivax malaria. The introduction of artemisinin-combination therapy was associated with a significant risk reduction in the vertical transmission of malaria. PMID:21908728

However, no data have been available to test the hypothesis that the high prevalence of CHD is reflected by the risk status of the childhood population. A randomly selected 2% population sample of 1015 children aged 12 and 15 years was studied to obtain baseline information on blood pressure, lipid profile, cigarette smoking, family history, physical activity, cardiorespiratory fitness, and dietary fat intake. Using available criteria thresholds, 15-23% displayed increased blood pressure, 12-25% had unfavourable lipid profiles, and 18-34% were overfat. In 15 year old children, 16-21% admitted being regular smokers, 26-34% displayed poor cardiorespiratory fitness, and 24-29% reported little physical activity in the previous week. Dietary analysis revealed relatively low polyunsaturated to saturated fatty acid ratios and high mean fat intakes, accounting for approximately 40% total daily energy. Despite the exclusion of family history from the analysis, 16% of the older children exhibited three or more risk factors. These results justify major concern about the level of potential coronary risk in Northern Ireland schoolchildren. Broadly based primary prevention strategies aimed at children are essential if future adult CHD mortality is to be reduced. PMID:8481039

    Background Little is known regarding the cardiovascular disease risk factors among Chamorros residing in the United States. Methods The Chamorro Directory International and the CDC's Behavioral Risk Factor Surveillance System Questionnaire (BRFSS) were used to assess the health related practices and needs of a random sample of 228 Chamorros. Results Inactivity, hypertension, elevated cholesterol and diabetes mellitus were more prevalent in this Chamorro sample compared to the US average. Participants who were 50-and-older or unemployed were more likely to report hypertension, diabetes and inactivity, but they were also more likely to consume more fruits and vegetables than their younger and employed counterparts. Women were more likely to report hypertension and diabetes, whereas men were more likely to have elevated BMI and to have never had their blood cholesterol checked. Conclusion The study provides data that will help healthcare providers, public health workers and community leaders identify where to focus their health improvement efforts for Chamorros and create culturally competent programs to promote health in this community.

    Although medical literature on social inequalities in perinatal health is qualitatively heterogeneous, it is quantitatively important and reveals the existence of a social gradient in terms of perinatal risk. However, published data regarding maternal health, if also qualitatively heterogeneous, are relatively less numerous. Nevertheless, it appears that social inequalities also exist concerning severe maternal morbidity as well as maternal mortality. Analyses are still insufficient to understand the mechanisms involved and explain how the various dimensions of the women social condition interact with maternal health indicators. Inadequate prenatal care and suboptimal obstetric care may be intermediary factors, as they are related to both social status and maternal outcomes, in terms of maternal morbidity, its worsening or progression, and maternal mortality.

    Fibroblast growth factor-23 (FGF23), a phosphate(Phos)-regulating hormone, is abnormally elevated in hypophosphataemic syndromes and an elevated FGF23 is a predictor of mortality in kidney disease. Recent findings suggest iron deficiency as a potential mediator of FGF23 expression and murine studies have shown in utero effects of maternal iron deficiency on offspring FGF23 and phosphate metabolism. Our aim was to investigate the impact of maternal iron status on infant FGF23 and mineral metabolites over the first 2years of life. Infants born to mothers with normal (NIn=25,) and low (LIn=25) iron status during pregnancy, from a mother-infant trial (ISRCTN49285450) in rural Gambia, West Africa, had blood and plasma samples analysed at 12, 24, 52, 78 and 104weeks (wk) of age. Circulating intact-FGF23 (I-FGF23), Phos, total alkaline phosphatase (TALP) and haemoglobin (Hb) decreased and estimated glomerular filtration rate increased over time [all P≤0.0001)]. C-terminal-FGF23 (C-FGF23) and TALP were significantly higher in LI compared with NI, from 52wk for C-FGF23 [Beta coefficient (SE) 18.1 (0.04) %, P=0.04] and from 24wk for TALP [44.7 (29.6) U/L, P=0.04]. Infant Hb was the strongest negative predictor of C-FGF23 concentration [-21% (4%) RU/mL, P≤0.0001], Phos was the strongest positive predictor of I-FGF23 [32.0(3.9) pg/mL, P≤0.0001] and I-FGF23 did not predict C-FGF23 over time [-0.5% (0.5%), P=0.3]. In conclusion, this study suggests that poor maternal iron status is associated with a higher infant C-FGF23 and TALP but similar I-FGF23 concentrations in infants and young children. These findings further highlight the likely public health importance of preventing iron deficiency during pregnancy. Whether or not children who are born to iron deficient mothers have persistently high concentrations of these metabolites and are more likely to be at risk of impaired bone development and pre-disposed to rickets requires further research.

    This study investigates mothers’ responses to infant communication among infants at heightened genetic risk (high risk) of autism spectrum disorder compared to infants with no such risk (low risk). A total of 26 infants, 12 of whom had an older sibling with autism spectrum disorder, were observed during naturalistic in-home interaction and semistructured play with their mothers at 13 and 18 months of age. Results indicate that overall, mothers of low-risk and high-risk infants were highly and similarly responsive to their infants’ communicative behaviors. However, examination of infant vocal and gestural communication development together with maternal verbal responses and translations (i.e. verbally labeling a gesture referent) suggests that delays in early communication development observed among high-risk infants may alter the input that these infants receive; this in turn may have cascading effects on the subsequent development of communication and language.

    Background and purpose - Results from case-control studies of maternal age at conception and risk of idiopathic clubfoot have been inconsistent. We conducted a meta-analysis to determine whether there is any association between maternal age at conception and the morbidity of idiopathic clubfoot. Methods - We searched PubMed-MEDLINE, EMBASE, and the Cochrane Library up to June 2015 and supplemented the search with manual searches of the reference lists of the articles identified. 11 studies published between 1990 and 2015 were pooled. We investigated heterogeneity in maternal age and whether publication bias might have affected the results. Results - Compared to a control group, maternal age at conception of between 20 and 24 years old was associated with an increased risk of occurrence of clubfoot (OR = 1.2, 95% CI: 1.1-1.4). No such association was found for the age groups of ≥ 35, 30-34, 25-29, and < 20 years. There was no heterogeneity in the age groups of ≥ 35, 30-34, and 20-24 years, moderate heterogeneity in the 25- to 29-year age group, and a large degree of heterogeneity in the group that was < 20 years of age. The prediction intervals for the age groups of 25-29 and < 20 years were 0.56 to 1.3 and -0.39 to 2.4, respectively. We found no evidence of significant publication bias. Interpretation - From the results of this meta-analysis of 11 studies, maternal age at conception between 20 to 24 years of age appears to be associated with an increased risk of occurrence of clubfoot.

    Objectives To identify the epidemiological risk factors for congenital anomalies (CAs) and the impact of these fetal malformations on the perinatal outcomes. Methods This prospective cohort study comprised 275 women whose fetuses had CAs. Maternal variables to establish potential risk factors for each group of CA and perinatal outcomes were evaluated. The primary outcome was CA. Secondary outcomes included: fetal growth restriction (FGR); fetal distress (FD); premature rupture of membranes (PROM); oligohydramnios or polyhydramnios; preterm delivery (PTD); stillbirth; cesarean section; low birth weight; Apgar score < 7 at the 1st and 5th minutes; need for assisted ventilation at birth; neonatal infection; need for surgical treatment; early neonatal death; and hospitalization time. Chi-square (χ(2)) test and multilevel regression analysis were applied to compare the groups and determine the effects of maternal characteristics on the incidence of CAs. Results The general prevalence of CAs was of 2.4%. Several maternal characteristics were associated to CAs, such as: age; skin color; level of education; parity; folic acid supplementation; tobacco use; and history of previous miscarriage. There were no significant differences among the CA groups in relation to FGR, FD, PROM, 1-minute Apgar score > 7, and need for assisted ventilation at birth. On the other hand, the prevalence of the other considered outcomes varied significantly among groups. Preterm delivery was significantly more frequent in gastrointestinal tract/abdominal wall defects. The stillbirth rate was increased in all CAs, mainly in isolated fetal hydrops (odds ratio [OR]: 27.13; 95% confidence interval [95%CI]: 2.90-253.47). Hospitalization time was higher for the urinary tract and congenital heart disease groups (p < 0.01). Neonatal death was significantly less frequent in the central nervous system anomalies group. Conclusion It was possible to identify several risk factors for CAs

    In fish, a series of maternal derived immune components have been identified in their eggs or embryos at very early stages, which are proposed to provide protections to themselves against pathogenic attacks from hostile environment. The phenomenon of maternal immunity has been also recorded in several invertebrate species, however, so far, very limited information about the maternal immune molecules are available. In this study, it was demonstrated maternal alpha2 macroglobulin (A2m) protein, an important innate immune factor, exists in the fertilized eggs of amphioxus Branchiostoma japonicum, an invertebrate chordate. Maternal mRNA of A2m was also detected in amphioxus embryos at very early developing stages. In addition, it was recorded that the egg lysate prepared from the newly fertilized eggs can inhibit the growth of both Gram-negative bacterium Escherichia coli and Gram-positive bacterium Staphylococcus aureus in a concentration dependent manner. The bacteriostatic activity can be reduced notably after precipitated A2m with anti-A2m antibody. Thus maternal A2m is partly attributed to the bacteriostatic activity. It was further demonstrated that recombinant A2m can bind to E. coli cells directly. All these points come to a result that A2m is a maternal immune factor existing in eggs of invertebrate chordate, which may be involved in defense their embryos against harmful microbes' attacks.

    Maternal influenza vaccination prevents influenza illness in both mothers and newborns. Results from some recent studies have suggested that influenza vaccination might also prevent adverse pregnancy outcomes, such as preterm birth. However, it is challenging to conduct epidemiologic studies to evaluate the benefits to the fetus of maternal influenza vaccination because the causal benefit of vaccination is likely only experienced by the small fraction of the cohort in whom influenza illness is prevented by vaccination. The plausibility of detecting true differences in risks between groups under such conditions is rarely discussed. We aimed to inform the interpretation of studies in which the fetal benefits of maternal influenza vaccination are evaluated by estimating detectable risk ratios and necessary sample sizes for different study scenarios. Estimates of rates of influenza illness, vaccine effectiveness, vaccine uptake, and preterm birth and of the association of influenza illness with preterm birth were identified from the published literature. We calculated detectable risk ratios for preterm birth in vaccinated versus unvaccinated women and the associated sample size requirements. Our results demonstrated that under most scenarios, plausible differences between groups will be extremely challenging to detect (risk ratios for preterm birth of 0.9 to 1.0) and will require sample sizes infeasible for prospective epidemiologic research. This suggests that the large fetal benefits from influenza vaccination observed in epidemiologic studies are unlikely to be causal. PMID:27365363

    Purpose Gestational diabetes mellitus (GDM) continues to be a significant health disorder triggering harmful complications in pregnant women and fetuses. Our knowledge of GDM epidemiology in Yemen is largely based on very limited data. The aim of this study was, therefore, to determine the prevalence and risk factors of GDM among pregnant women in Dhamar governorate, Yemen. Patients and methods A total of 311 subjects were randomly selected for this cross sectional survey. Health history data and blood samples were collected using a pretested questionnaire. To determine the prevalence of GDM, the fasting and random blood glucose techniques were applied according to the recommendations of the American Diabetes Association, using alternative methods that are more convenient to the targeted population. Poisson’s regression model incorporating robust sandwich variance was utilized to assess the association of potential risk factors in developing GDM. Results The prevalence of GDM was found to be 5.1% among the study population. Multivariate analysis confirmed age ≥30 years, previous GDM, family history of diabetes, and history of polycystic ovary syndrome as independent risk factors for GDM prevalence. However, body mass index ≥30 kg/m2 and previous macrosomic baby were found to be dependent risk factors. Conclusion This study reports new epidemiological information about the prevalence and risk factors of GDM in Yemen. Introduction of proper maternal and neonatal medical care and health education are important in order to save the mother and the baby. PMID:26869814
