Abstract
Research from several high-income countries links early menarche with an increased risk for sexual violence. However, the role of early menarche in adolescent girls' and young women's sexual violence risk in sub-Saharan Africa, where sexual violence rates are high, is not well understood. The current study explores the association between early menarche and sexual violence in Ghana with secondary analysis of data collected from 700 adolescent girls and young women followed over three years. Logistic regressions were used to assess the cross-sectional association between early menarche and sexual violence. Generalised estimating equations were used to assess whether the association between early menarche and sexual violence persisted over time. Inverse odds weighting was used to test potential mediators of the association between early menarche and sexual violence. Sexual violence was fairly common in the study sample, with 27% reporting having experienced sexual violence at baseline, and approximately 50% at year three. Early menarche was associated with 72% greater odds of having experienced sexual violence at baseline (95% confidence interval: 1.01-2.93). However, the odds ratio attenuated and lost significance over the three-year study period, with a lower risk of sexual violence among girls with early menarche at year three. Neither child marriage nor early sexual initiation significantly mediated the association between early menarche and sexual violence. The findings suggest that early-maturing girls may be particularly vulnerable to sexual violence in early adolescence, thus necessitating prevention interventions around the time of menarche to reduce the risk for sexual violence.

Abstract
BACKGROUND Prosocial behavior has positive social, cognitive, and physical health effects on the individual exhibiting the behavior as well as on society as a whole, and is integral to overall mental and physical wellbeing. The development of prosocial behavior is rooted in early childhood and learned through observation. As such, those spending time with children, especially their caregiver, play a critical role in their prosocial development. The current study investigates the impact of caregiver mental health on the prosocial development of young children over time. METHODS This paper presents a secondary analysis of child prosocial development in the Asenze Study, a longitudinal, population-based cohort study based in KwaZulu-Natal, South Africa. Children were followed-up over time from an average age of five to seven years along with their caregivers. Linear GEE regression analysis was used to assess whether a change in presence of a mental health disorder in a caregiver during this 2-year interval (using the Client Diagnostic Questionnaire) impacted the development of their child's prosocial behavior (using the Strengths and Difficulties Questionnaire). RESULTS After adjusting for early child-care, child HIV status, SDQ child prosocial subscale, SDQ total difficulties score, and household order score (CHAOS), children whose caregivers acquired a mental health disorder had a significantly smaller increase in prosocial behavioral development compared to children whose caregivers never had a mental health disorder. CONCLUSIONS Identifying contextually relevant modifiable factors such as this will help stimulate the development of interventions to promote prosocial development in childhood.

Abstract
We explored the association between household alcohol use and behavior problems among South-African children, using data from the Asenze study, a population-based cohort of South African children and their caregivers. Household alcohol use and child behavior were assessed when children were 6-8 years old. To examine the association, we performed linear regressions. The sample included 1383 children with complete data under the care of 1251 adults. Children living in a household where self-reported caregiver alcohol use was scored as hazardous (4.6%) had higher levels of problem behavior (β = 1.94, 95% CI 0.06-3.82). There were no statistically significant associations between reported hazardous alcohol use by another member of the household (14.5%) and child problem behavior. Hazardous household alcohol use was associated with child problem behavior and this effect appeared to be mainly driven by primary caregiver use.

Abstract
INTRODUCTION Low birth weight (LBW), biological vulnerability that includes preterm birth (PTB) and small for gestational age (SGA), is associated with reduced maternal sensitivity ("making accurate inferences about an infant's physical and emotional needs and responding appropriately") and impaired infant cognitive development. However, research does not examine if preterm birth, SGA, or both drive these associations. This study separated these measures of biological vulnerability to examine associations of LBW, PTB, and SGA with maternal sensitivity and infant cognitive development (controlling for maternal depression, breastfeeding, and demographic covariates). METHODS The sample included 6900 9-month-old infants from the Early Childhood Longitudinal Study-Birth Cohort and used birth certificate data, maternal interviews, assessments of maternal sensitivity and infant cognitive development. Multiple linear regressions examined LBW, PTB, and SGA associations with concurrent measures of maternal sensitivity and infant cognition. RESULTS Of the biological vulnerabilities, preterm birth had the strongest negative association with maternal sensitivity (F1,6450 = 29.48 versus 15.33 and 5.51, ps < .001) and infant cognitive development (F1,6450) = 390.65 versus 248.02 and 14.43, ps < .001). In the final regression model, preterm birth and maternal sensitivity were uniquely associated with infant cognitive development (R2 = .05, p < .001), after controlling for maternal depression, breastfeeding, and demographics. CONCLUSION In this nationally representative infant sample infants, PTB had a stronger negative association with both maternal sensitivity and infant cognitive development in comparison to SGA or LBW. The LBW designation combines infants born preterm with SGA infants, potentially minimizing differences in developmental outcomes of PTB and SGA infants.

Abstract
BACKGROUND Adverse childhood events (ACEs) are associated with negative health effects in adulthood. Despite knowledge of these later impacts, little is known about the earlier effect of ACEs on later child behaviour in low- and middle-income countries (LMIC). METHODS The population-based Asenze cohort study was implemented in a peri-rural area of KwaZulu-Natal, South Africa, comprising five Zulu tribal areas. Two waves of data were examined: family information and ACEs exposure when children were on average 5 years old and child behaviour problems (Strengths and Difficulties Questionnaire [SDQ]) approximately 2 years later (average age 7 years). Logistic regression analysis was used to examine unadjusted and adjusted relationships between cumulative ACEs experienced and the SDQ total scores (dichotomized as top 10% vs. the rest) as well as selected SDQ subscales. RESULTS A significant relationship between increased ACE exposure and SDQ total score was observed. The same relationship was also seen for the SDQ emotional symptoms and conduct problem subscales, but not for hyperactivity. The results of a sensitivity analysis excluding intimate partner violence from the ACEs measure demonstrated similar results. CONCLUSIONS There is an association between exposure to ACEs and later child behaviour problems within this LMIC population demonstrating an early negative impact for ACEs. While previous research has focused on the effects of ACEs on adult health, this study provided evidence for an earlier relationship between ACEs and child behaviour problems that may be a part of the mechanism through which later health effects arise.

Abstract
The Asenze cohort is set in South Africa, a middle-income country impacted by one of the highest global rates of people living with HIV/AIDS and high levels of socioeconomic inequality. This longitudinal population-based cohort of children and their primary caregivers assesses household and caregiver functioning, child health, social well-being, and neuro-development from childhood through adolescence. Almost 1,600 children born at the peak of the human immunodeficiency virus epidemic (2003-2005) were followed (with their primary caregivers) in 3 waves, between 2008 and 2021, at average ages of 5, 7, and 16. Wave 3 is currently underway, having assessed over 1,100 of the original wave 1 children. Wave 4 begins in 2022. The study, with a dyadic structure, uses a broad range of measures, validated in South Africa or recommended for global use, that address physical, social and neuro-development in childhood and adolescence, and the social, health, and psychological status of children's primary caregivers. The Asenze study deepens our understanding of childhood physical, cognitive, and social abilities and/or disabilities, including risk-taking behaviors, and biological, environmental, and social determinants of health. We anticipate the findings will contribute to the development of community-informed interventions to promote well-being in this South African population and elsewhere.

Abstract
Background Previous research has established that exposure to high maternal sensitivity is positively associated with advances in infant cognitive development. However, there are many fixed and modifiable factors that influence this association. This study investigates whether the association between maternal sensitivity and infant cognitive development in the first year of life is accounted for by other factors, such as breastfeeding, maternal depressive symptoms, maternal alcohol use, infant birth weight or demographic covariates. Methods Using data from the Early Childhood Longitudinal Study-Birth (ECLS-B) Cohort, a nationally representative sample of U.S. born children, multi-variable regression analyses was used to examine whether breastfeeding, maternal depressive symptoms and alcohol use were associated with maternal sensitivity, as measured by the Nursing Child Assessment Teaching Scale (NCATS), and with infant cognitive development, as measured by the Bayley Scales of Infant Development, Short Form, Research Edition, after controlling for demographic covariates (infant sex, maternal age, education, race/ethnicity, income, parity, family structure) and infant birth weight. Results Breastfeeding, depressive symptoms and alcohol use were not associated with maternal sensitivity scores after controlling for demographic covariates and infant birth weight. However, breastfeeding (β = .079, p < .001), depressive symptoms (β = −.035, p < .05), and maternal sensitivity (β = .175, p < .001) were each significantly associated with infant cognitive development scores, even after controlling for demographic covariates and birthweight (R2 = .053, p < .001). The association between maternal sensitivity and infant cognitive development did not attenuate after adjusting for breastfeeding. Instead, both sensitivity and breastfeeding independently contributed to higher infant cognitive development scores. Conclusion Maternal sensitivity and breastfeeding are separate means to advancing infant cognitive development. This study is significant because it is the first to examine breastfeeding, maternal depressive symptoms and alcohol use together, upon the association between maternal sensitivity and infant cognitive development, after adjusting for demographic covariates and infant birthweight. Maternal sensitivity, a measurable quality, advances infants’ cognitive development. Moreover, sensitivity and breastfeeding had independent effects upon cognitive development after controlling for multiple fixed and modifiable covariates. Understanding factors impacting the association between sensitivity and infant cognitive development provide avenues for developing more effective parenting interventions.

Abstract
Exposure to alcohol misuse is considered an adverse childhood experience impacting on neurodevelopmental and behavioural outcomes in adolescents including substance use, mental illness, problem behaviours, suicidality, and teenage pregnancy. Most research on this issue has focussed on higher income countries, whereas patterns of alcohol use and related factors may be different in low- and middle-income countries (LMICs). This systematic review therefore seeks to collate all published studies from 1990-2020 on the topic set in LMICs. 43 studies were included, totalling 70,609 participants from 18 LMICs. Outcomes assessed included: substance use; depression/anxiety; suicidal ideation; problem behaviour; emotional dysfunction; teenage pregnancy; and self-harm. Despite heterogeneity in the studies identified, this review documented some association between exposure to household alcohol misuse and adverse adolescent outcomes in LMICs, including mental health problems, problem behaviours, and suicidality. The mechanisms leading to these outcomes are likely varied, and further research in different socio-economic and cultural contexts, particularly in the form of longitudinal studies, is called for.

Abstract
Perinatal HIV infection is associated with delayed neurocognitive development, but less is known about children perinatally HIV-exposed but uninfected (CHEU). We compared cognitive and language outcomes in 4-6-year old CHEU versus children HIV-unexposed and uninfected (CHUU) and children living with HIV (CLHIV). We enrolled 1,581 children (77% of the child population) in five communities in KwaZulu-Natal, South Africa. Children completed: Grover-Counter Scale of cognitive development, sub-scales of the Kaufman Assessment Battery for Children, Reynell Developmental Language Scales. HIV status of children and primary caregivers was determined by repeated rapid tests or report of prior testing. We conducted a cross-sectional multivariable linear regression on 922 dyads with complete data (257 CHEU, 627 CHUU, 38 CLHIV). On all outcome measures, CHEU and CHUU groups had comparable scores; CLHIV scored significantly lower. Emerging global progress toward the elimination of vertical HIV transmission may not only reduce mortality, but also positively impact child development.

Abstract
Background The Asenze study has the long-term goal of promoting better physical, cognitive and psychosocial functioning of children in a rural area in KwaZulu-Natal, 50 km from Durban with a view to planning interventions to promote growth and development for very young children. The specific objective in this paper was to provide information for the Child Health and Development project of the Valley Trust to assist with intervention planning. The broader goal was to assess developmental delays in communities ravaged by the HIV epidemic.The Asenze study was designed in two phases from 2008 and 2012. The current paper reports on 1581 4-6years old children in the baseline phase (2008-2010) in the five adjacent tribal areas in the study area. Method The participants included all the 4 - 6 year olds whose parents had consented to inclusion in the project and their caregivers. Data were derived from a brief questionnaire administered in the homes of participants, and subsequently from medical and psychological assessments of the children and their caregivers at the Asenze clinic. The association between child factors and other factors (geographic area, socioeconomic status (SES), parental level of education, the child's pre-school education) on the one hand and, the child's cognitive performance (as measured by the Grover Counter and subtests of the KABC-11) were analysed. Linear regression models were employed to determine which predictor variables of interest in a model were associated with the children's cognitive scores as the dependent variables. Results Based on the data, the principal factors associated with children's cognitive outcomes were height-for-age z-score (HAZ), preschool education and the area of residence, Generally children who had low cognitive scores were more often stunted (as defined by the WHO anthropometric tables), had not had pre-school education, and came from areas less favourable in terms of local infrastructure and access to employment opportunities and arable land. Conclusion The finding from this cross-sectional analysis of baseline data showed that in addition to height for age and pre-school education, which are commonly thought to impact on cognition, the local authority area where the children lived was associated with their scores on cognitive tests. This has implications for intervention planning. The functioning of local government in promoting the type of community development which will protect the rights of children should be taken into account.

Abstract
OBJECTIVE To investigate the relationship between prenatal geophagy, maternal prenatal haematological indices, malaria, helminth infections and cognitive and motor development among offspring. METHODS At least a year after delivery, 552 of 863 HIV-negative mothers with singleton births who completed a clinical trial comparing the efficacy of sulfadoxine-pyrimethamine and mefloquine during pregnancy in Allada, Benin, responded to a nutrition questionnaire including their geophagous habits during pregnancy. During the clinical trial, helminth infection, malaria, haemoglobin and ferritin concentrations were assessed at 1st and 2nd antenatal care visits (ANV) and at delivery. After the first ANV, women were administered daily iron and folic acid supplements until three what? post-delivery. Singleton children were assessed for cognitive function at age 1 year using the Mullen Scales of Early Learning. RESULTS The prevalence of geophagy during pregnancy was 31.9%. Pregnant women reporting geophagy were more likely to be anaemic (AOR = 1.9, 95% CI [1.1, 3.4]) at their first ANV if they reported geophagy at the first trimester. Overall, prenatal geophagy was not associated with maternal haematological indices, malaria or helminth infections, but geophagy during the third trimester and throughout pregnancy was associated with poor motor function (AOR = -3.8, 95% CI [-6.9, -0.6]) and increased odds of geophagous behaviour in early childhood, respectively. CONCLUSIONS Prenatal geophagy is not associated with haematological indices in the presence of micronutrient supplementation. However, it may be associated with poor child motor function and infant geophagy. Geophagy should be screened early in pregnancy.

Abstract
OBJECTIVE When testing African children with developmental and cognitive standardized tests from high-income countries (HIC), investigators are uncertain as to whether to apply the HIC norms for these tests when standardizing a child's raw-score performance on the basis of age. The present study compared the construct validity of both raw and HIC-based standardized scores for the Mullen Scales of Early Learning (MSEL) and the Kaufman Assessment Battery in Children - 2nd edition (KABC-II) for Beninese children in a rural setting from three to six years of age. METHODS Seventy-four children 3-4 yrs of age were assessed with the MSEL, and 61 eligible older children (5-6 yrs of age) were assessed with the KABC-II. Assessors spoke the instructions to the children and caregivers for the assessment items in the local language. The developmental quality of the home environment was evaluated with the Caldwell Home Observation for Measurement of the Environment (HOME) inventory, and a material possessions and housing quality checklist was used as a measure of socio-economic status (SES). Children's mothers were given the Raven's Progressive Matrices test (nonverbal cognitive ability), and the Edinburgh Postpartum Depression Scale (EPDS) (emotional wellbeing). RESULTS For the MSEL, the 4-yr old group performed significantly better than the 3-yr old group on both the raw and standardized score comparisons for all scales. These differences were attenuated when using standardized scores, although the MSEL standardized cognitive composite score was still highly significant between years of age. When comparing 5- to 6-yr olds on KABC-II subtest and global scale performance, comparisons between the raw and standardized mean score performances were much less consistent. Generally, 6-yr olds performed significantly better than 5-yr olds on the raw score comparisons on the KABC-II subtests, but not so for standardized scores. Parent-child interactions assessed through the HOME measure was associated with both raw and standardized MSEL cognitive composite score outcomes on a multiple regression analysis. SES was the only significant predictor for KABC-II raw and standardized outcomes. CONCLUSION Standardization using HIC norms was not optimal, resulting in minimal impact to account for age when using the MSEL, and lower scores for oldest children compared with youngest children when using the KABC2. This is likely due to children in Benin drifting away from HIC-based norms with each passing year of age, systematically lowering standardized performance measures. These findings support the importance of having a local comparison group of reference or control children to allow for adjusted (for age, HOME, and SES) raw score comparisons when using western-based tests for developmental and neuropsychological evaluation.

Abstract
BACKGROUND Little is known about the prevalence of child mental health (MH) problems in sub-Saharan Africa, where poverty, HIV, and family disruption increase risk. One barrier is the lack of MH assessment tools lay staff can validly and reliably administer in settings with few MH professionals. METHODS In a South African (SA) peri-urban cohort, we examined psychometric properties of the Strengths and Difficulties Questionnaire (SDQ), a widely used measure of child emotional and behavioral functioning. Data come from a large population-based study (N=1581) of children 4-6 years old. Lay fieldworkers administered the SDQ in isiZulu to caregivers at baseline and two years later. Exploratory factor analysisexamined whether the established SDQ five-factor structure and Total Difficulties score would be replicated. The psychometric model was tailored for ordinal items, and target factor rotation was used. RESULTS Total Difficulties, Emotional symptoms and Prosocial behavior factors were supported, with partial support for Conduct problems. Peer relationships and Hyperactivity/inattentive subscale items loaded poorly. Subscale Cronbach's alphas ranged from 0.29 (Peers) to 0.62 (Emotional). Internal consistency of Total Difficulties score was acceptable (0.74); 30% scored in the abnormal range on Total Difficulties, based on UK norms. CONCLUSIONS SDQ scores in our sample suggest young children in SA are at high risk for MH problems. The SDQ, particularly the Total Difficulties score, may be a useful screening tool in SA. Yet, some subscales did not work in this language and context; if social skills and hyperactivity/inattention arebeing considered, modification or additional measures may be needed.

Abstract
BACKGROUND Research in high-income countries has repeatedly demonstrated that intimate partner violence (IPV) experienced by women negatively affects the health and behavior of children in their care. However, there is little research on the topic in lower- and middle-income countries. The population-based Asenze Study gathered data on children and their caregivers in KwaZulu-Natal, South Africa. This data analysis explores the association of caregiver IPV on child behavior outcomes in children <12 years old and is the first such study in Africa. METHODS This population-based study was set in 5 Zulu tribal areas characterized by poverty, food insecurity, unemployment, and a high HIV prevalence. The Asenze Study interviewed caregivers via validated measures of IPV, alcohol use, caregiver mental health difficulties, and child behavior disorders in their preschool children. RESULTS Among the 980 caregivers assessed, 37% had experienced IPV from their current partner. Experience of partner violence (any, physical, or sexual) remained strongly associated with overall child behavior problems (odds ratio range: 2.46-3.10) even after age, HIV status, cohabitation with the partner, alcohol use, and posttraumatic stress disorder were accounted for. CONCLUSIONS Childhood behavioral difficulties are associated with their caregiver's experience of IPV in this population, even after other expected causes of child behavior difficulties are adjusted for. There is a need to investigate the longer-term impact of caregiver partner violence, particularly sexual IPV, on the health and well-being of vulnerable children in lower- and middle-income countries. Studies should also investigate whether preventing IPV reduces the occurrence of childhood behavior difficulties.

Abstract
Research is just beginning to explore the intersection of bullying and relationship violence. The relationship between these forms of youth aggression has yet to be examined in diverse urban centers, including New York City (NYC). This study seeks to identify intersections of joint victimization from bullying and electronic bullying (e-bullying) with physical relationship violence (pRV). This study examines data from the NYC Youth Risk Behavior Survey (YRBS), a representative sample of NYC public high school students, to assess the concurrent victimization from bullying at school and e-bullying with pRV, operationalized as physical violence by a dating partner in the past 12 months. Students who reported being bullied at school and e-bullied had increased odds (bullied: OR = 2.5, 95% CI [2.1, 2.9]; e-bullied: OR = 3.0, 95% CI [2.6, 3.5]) of also being victimized by pRV compared with those who did not report being bullied or e-bullied. In logistic regression models, being bullied at school and being e-bullied remained significant predictors of students' odds of reporting pRV (bullied: AOR = 2.6, 95% CI [2.2, 3.1]; e-bullied: AOR = 3.0, 95% CI [2.5, 3.6]) while controlling for race, gender, sexual orientation, and age. This research is the first to assess the intersection of victimization from bullying and e-bullying with pRV in a large, diverse, random sample of urban high school students. In this sample, students who report being bullied or e-bullied are more likely also to report pRV than students who have not been bullied or e-bullied. This research has potential implications for educators, adolescent health and social service providers, and policy makers to tailor programs and enact policies that jointly address bullying and pRV. Future studies are needed to longitudinally assess both victimization from and perpetration of bullying and pRV.

Abstract
OBJECTIVE To investigate the impact of prenatal maternal iron deficiency (ID) on cord blood serum ferritin (CBSF) concentration and infant cognitive and motor development. METHODS Our prospective cohort study included 636 mother-singleton child pairs from 828 eligible pregnant women who were enrolled during their first antenatal care (ANC) visit in Allada, Benin, into a clinical trial comparing the efficacy of mefloquine and sulfadoxine-pyrimethamine. Venous blood samples of women were assessed for ferritin and hemoglobin concentrations at the first and second ANC visits (occurring at least 1-month apart) and at delivery. Women were prescribed daily iron and folic acid supplements throughout pregnancy. Hematologic examinations were repeated for cord blood at birth. At age 1 year, cognitive and motor functions of children were assessed by using the Mullen Scales of Early Learning. RESULTS The prevalence of prenatal ID at first and second ANC visits, and at delivery was 30.5%, 34.0%, and 28.4%, respectively. CBSF concentrations were similar between ID and non-ID pregnant women. Neither prenatal ID nor CBSF concentration was associated with poor cognitive or gross motor function of children at age 1 year. CBSF concentrations were lower among mothers who had ID anemia (IDA) at delivery compared with non-IDA pregnant women (adjusted mean difference: -0.2 [95% confidence interval: -0.4 to -0.0]). CONCLUSIONS In a malaria-endemic region, ID in pregnancy in the context of iron supplementation is neither associated with CBSF concentration nor with infant cognitive and motor development. Prenatal IDA around the time of delivery is associated with lower CBSF concentrations.

Abstract
Background and Objectives Alcohol abuse, a significant health problem in South Africa, affects the ability of adults to care for children. Little is known regarding risky alcohol use among child caregivers there. A large population-based study examined the prevalence of, and factors associated with, risky drinking among caregivers of young children in KwaZulu-Natal, South Africa comparing the use of the Alcohol Use Disorders Identification Test (AUDIT) and the AUDIT-C screens for hazardous or harmful drinking (referred to here as risky drinking). Methods 83 % of child caregivers from five tribal areas were interviewed using the 10-question AUDIT to screen for risky drinking. The AUDIT-C screen, a subset of AUDIT questions, targets alcohol consumption and binge drinking. Factors associated with risky drinking were investigated using logistic regression. Results 1434 caregivers participated, 98 % female. Sixteen percent reported ever drinking alcohol. Based on AUDIT criteria for risky drinking, 13 % of the sample scored as moderate drinkers, 2 % as hazardous users, and 1 % as harmful or dependent users (identifying 3 % as risky drinkers). Using AUDIT-C criteria to identify risky drinking significantly increased the proportion of caregivers identified as risky drinkers to 9 %. In multivariate analyses, factors associated with risky drinking were similar in both screens: partner violence, smoking, HIV-infection, caring for a child with disabilities. Conclusions for Practice Since the AUDIT-C identified risky alcohol use not otherwise detected with the full AUDIT, and since resources for screening in health care settings is limited, the AUDIT-C may be a more appropriate screen in populations where binge drinking is common.

Abstract
BACKGROUND Given the high prevalence of mental health (MH) and substance abuse problems in low-to-middle income countries, the scarcity of MH professionals and the negative impact of psychiatric disorders on caregivers of young children, there is significant need for brief evidence-based screening tools for lay counselors to assist with MH assessment. This study aimed to validate a brief screening tool to assess psychiatric and substance use disorders, the Client Diagnostic Questionnaire (CDQ), in South Africa (SA). METHODS Data are from a longitudinal study of health and psychosocial needs in preschool children in SA. Participants included 322 Zulu-speaking, female caregivers. Following procedures of the US CDQ validation study, lay counselors interviewed participants using the translated Zulu CDQ. Subsequently a psychologist conducted a full psychiatric assessment guided by the CDQ questions. Analyses examined sensitivity, specificity and overall accuracy, comparing lay counselor and psychologist assessment. RESULTS Sensitivity (73%), specificity (81%) and overall accuracy (79%) were good for the variable indicating presence of 'any diagnosis.' Among those cases identified by the psychologist as having any psychiatric diagnosis, over 70% were correctly identified by lay counselors using the CDQ (i.e., positive predictive value was greater than 70%). The false positive rate was relatively low (19%). Specificity for 'any disorder' (including substance use) and 'any psychiatric disorder' were 81% and 79%. CONCLUSIONS The isiZulu CDQ is a sensitive and valid MH diagnostic screener that can be used by lay counselors with limited MH training to identify those in need of treatment and target extremely scarce MH professionals. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGES South Africa (SA), a country heavily impacted by poverty, HIV and the legacy of Apartheid, has a high prevalence of mental health (MH) and substance abuse problems. In SA and other low-and-middle-income-countries (LMIC) there is a dearth of MH professionals. This study examined use and validity of the Client Diagnostic Questionnaire (CDQ), a brief diagnostic MH screening tool designed for use by lay counselors in HIV-affected populations. Comparing lay counsellor diagnoses on the CDQ to clinician assessment, sensitivity, specificity and overall accuracy were good at the level of 'any diagnosis.' The CDQ can be used effectively in SA and other LMIC with limited MH services to enable appropriate and efficient referral of individuals in primary care settings, supporting caregivers and the children in their care.

Abstract
BACKGROUND Intimate partner abuse is common worldwide, damaging the short- and long-term physical, mental, and emotional health of survivors and children. Advocacy may contribute to reducing abuse, empowering women to improve their situation by providing informal counselling and support for safety planning and increasing access to different services. Advocacy may be a stand-alone service, accepting referrals from healthcare providers, or part of a multi-component (and possibly multi-agency) intervention provided by service staff or others. OBJECTIVES To assess the effects of advocacy interventions within or outside healthcare settings in women who have experienced intimate partner abuse. SEARCH METHODS In April 2015, we searched CENTRAL, Ovid MEDLINE, EMBASE, and 10 other databases. We also searched WHO ICTRP, mRCT, and UK Clinical Research Network (UKCRN), and examined relevant websites and reference lists with forward citation tracking of included studies. For the original review we handsearched six key journals. We also contacted first authors of eligible papers and experts in the field. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing advocacy interventions for women with experience of intimate partner abuse versus no intervention or usual care (if advocacy was minimal and fewer than 20% of women received it). DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias and undertook data extraction. We contacted authors for missing information needed to calculate statistics for the review and looked for adverse events. MAIN RESULTS We included 13 trials involving 2141 participants aged 15 to 65 years, frequently having low socioeconomic status.The studies were quite heterogeneous in terms of methodology, study processes and design, including with regard to the duration of follow-up (postintervention to three years), although this was not associated with differences in effect. The studies also had considerable clinical heterogeneity in relation to staff delivering advocacy; setting (community, shelter, antenatal, healthcare); advocacy intensity (from 30 minutes to 80 hours); and abuse severity. Three trials evaluated advocacy within multi-component interventions. Eleven measured some form of abuse (eight scales), six assessed quality of life (three scales), and six measured depression (three scales). Countries and ethnic groups varied (one or more minority ethnic groups in the USA or UK, and local populations in Hong Kong and Peru). Setting was associated with intensity and duration of advocacy.Risk of bias was high in five studies, moderate in five, and low in three. The quality of evidence (considering multiple factors such as risk of bias, study size, missing data) was moderate to low for brief advocacy and very low for intensive advocacy. Incidence of abuse Physical abuseModerate quality pooled data from two healthcare studies (moderate risk of bias) and one community study (low risk of bias), all with 12-month follow-up data, showed no effect on physical abuse for brief (< 12 hours) advocacy interventions (standardised mean difference (SMD) 0.00, 95% confidence interval (CI) - 0.17 to 0.16; n = 558). One antenatal study (low risk of bias) showed an association between brief advocacy and reduced minor physical abuse at one year (mean difference (MD) change - 1.00, 95% CI - 1.82 to - 0.18; n = 110). An antenatal, multi-component study showed a greater likelihood of physical abuse ending (odds ratio (OR) 0.42, 95% CI 0.23 to 0.75) immediately after advocacy (number needed to treat (NNT) = 8); we cannot exclude impact from other components.Low to very low quality evidence from two intensive advocacy trials (12 hours plus duration) showed reduced severe physical abuse in women leaving a shelter at 24 months (OR 0.39, 95% CI 0.20 to 0.77; NNT = 8), but not at 12 or 36 months. Sexual abuseMeta-analysis of two studies (n = 239) showed no effect of advocacy on sexual abuse (SMD - 0.12, 95% CI - 0.37 to 0.14), agreeing with the change score (MD - 0.07, 95% CI - 0.30 to 0.16) from a third study and the OR (0.96, 95% CI 0.44 to 2.12) from a fourth antenatal, multi-component study. Emotional abuseOne study in antenatal care, rated at low risk of bias, showed reduced emotional abuse at ≤ 12-month follow-up (MD (change score) - 4.24, 95% CI - 6.42 to - 2.06; n = 110). Psychosocial health Quality of lifeMeta-analysis of two studies (high risk of bias) showed intensive advocacy slightly improved overall quality of life of women recruited from shelters (MD 0.23, 95% CI 0.00 to 0.46; n = 343) at 12-month follow-up, with greater improvement in perceived physical quality of life from a primary care study (high risk of bias; MD 4.90, 95% CI 0.98 to 8.82) immediately postintervention. Depression Meta-analysis of two studies in healthcare settings, one at high risk of bias and one at moderate risk, showed that fewer women developed depression (OR 0.31, 95% CI 0.15 to 0.65; n = 149; NNT = 4) with brief advocacy. One study at high risk of bias reported a slight reduction in depression in pregnant women immediately after the intervention (OR 0.51, 95% CI 0.20 to 1.29; n = 103; NNT = 8).There was no evidence that intensive advocacy reduced depression at ≤ 12-month follow-up (MD - 0.14, 95% CI - 0.33 to 0.05; 3 studies; n = 446) or at two years (SMD - 0.12, 95% CI - 0.36 to 0.12; 1 study; n = 265). Adverse effectsTwo women died, one who was murdered by her partner and one who committed suicide. No evidence links either death to study participation. AUTHORS' CONCLUSIONS Results suggest some benefits from advocacy. However, most studies were underpowered. Clinical and methodological heterogeneity largely precluded pooling of trials. Therefore, there is uncertainty about the magnitude of benefit, the impact of abuse severity, and the setting.Based on the evidence reviewed, intensive advocacy may improve short-term quality of life and reduce physical abuse one to two years after the intervention for women recruited from domestic violence shelters or refuges. Brief advocacy may provide small short-term mental health benefits and reduce abuse, particularly in pregnant women and for less severe abuse.

Abstract
BACKGROUND Intimate partner violence (IPV) damages individuals, their children, communities, and the wider economic and social fabric of society. Some governments and professional organisations recommend screening all women for IPV rather than asking only women with symptoms (case-finding). Here, we examine the evidence for whether screening benefits women and has no deleterious effects. OBJECTIVES To assess the effectiveness of screening for IPV conducted within healthcare settings on identification, referral, re-exposure to violence, and health outcomes for women, and to determine if screening causes any harm. SEARCH METHODS On 17 February 2015, we searched CENTRAL, Ovid MEDLINE, Embase, CINAHL, six other databases, and two trial registers. We also searched the reference lists of included articles and the websites of relevant organisations. SELECTION CRITERIA Randomised or quasi-randomised controlled trials assessing the effectiveness of IPV screening where healthcare professionals either directly screened women face-to-face or were informed of the results of screening questionnaires, as compared with usual care (which could include screening that did not involve a healthcare professional). DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias in the trials and undertook data extraction. For binary outcomes, we calculated a standardised estimation of the odds ratio (OR). For continuous data, either a mean difference (MD) or standardised mean difference (SMD) was calculated. All are presented with a 95% confidence interval (CI). MAIN RESULTS We included 13 trials that recruited 14,959 women from diverse healthcare settings (antenatal clinics, women's health clinics, emergency departments, primary care) predominantly located in high-income countries and urban settings. The majority of studies minimised selection bias; performance bias was the greatest threat to validity. The overall quality of the body of evidence was low to moderate, mainly due to heterogeneity, risk of bias, and imprecision.We excluded five of 13 studies from the primary analysis as they either did not report identification data, or the way in which they did was not consistent with clinical identification by healthcare providers. In the remaining eight studies (n = 10,074), screening increased clinical identification of victims/survivors (OR 2.95, 95% CI 1.79 to 4.87, moderate quality evidence).Subgroup analyses suggested increases in identification in antenatal care (OR 4.53, 95% CI 1.82 to 11.27, two studies, n = 663, moderate quality evidence); maternal health services (OR 2.36, 95% CI 1.14 to 4.87, one study, n = 829, moderate quality evidence); and emergency departments (OR 2.72, 95% CI 1.03 to 7.19, three studies, n = 2608, moderate quality evidence); but not in hospital-based primary care (OR 1.53, 95% CI 0.79 to 2.94, one study, n = 293, moderate quality evidence).Only two studies (n = 1298) measured referrals to domestic violence support services following clinical identification. We detected no evidence of an effect on referrals (OR 2.24, 95% CI 0.64 to 7.86, low quality evidence).Four of 13 studies (n = 2765) investigated prevalence (excluded from main analysis as rates were not clinically recorded); detection of IPV did not differ between face-to-face screening and computer/written-based assessment (OR 1.12, 95% CI 0.53 to 2.36, moderate quality evidence).Only two studies measured women's experience of violence (three to 18 months after screening) and found no evidence that screening decreased IPV.Only one study reported on women's health with no differences observable at 18 months.Although no study reported adverse effects from screening interventions, harm outcomes were only measured immediately afterwards and only one study reported outcomes at three months.There was insufficient evidence on which to judge whether screening increases uptake of specialist services, and no studies included an economic evaluation. AUTHORS' CONCLUSIONS The evidence shows that screening increases the identification of women experiencing IPV in healthcare settings. Overall, however, rates were low relative to best estimates of prevalence of IPV in women seeking healthcare. Pregnant women in antenatal settings may be more likely to disclose IPV when screened, however, rigorous research is needed to confirm this. There was no evidence of an effect for other outcomes (referral, re-exposure to violence, health measures, lack of harm arising from screening). Thus, while screening increases identification, there is insufficient evidence to justify screening in healthcare settings. Furthermore, there remains a need for studies comparing universal screening to case-finding (with or without advocacy or therapeutic interventions) for women's long-term wellbeing in order to inform IPV identification policies in healthcare settings.

Abstract
OBJECTIVE To explore the relationship between prenatal hemoglobin (Hb) concentration and infant cognitive and motor functions. METHODS Our prospective cohort study included 1-year-old children born to women enrolled at their first antenatal care (ANC) visit in Allada, Benin, before 29 weeks of pregnancy, within a trial comparing the efficacy of sulfadoxine-pyrimethamine and mefloquine. Hb concentrations of pregnant women were determined from venous blood samples collected at first and second ANC visits of at least 1-month interval and at delivery. Women were prescribed oral iron, folic acid, and anthelminthics after the first ANC visit. A total of 636 children (76.8% of eligible children) were assessed by trained research nurses for cognitive and motor functions by using the Mullen Scales of Early Learning. RESULTS Prevalence of anemia (Hb < 110 g/L) decreased from 67.0% at first ANC visit (mean gestational age [SD], 22.1 [4.0] weeks) to 38.4% at delivery. Mean (SD) Hb concentrations increased from 103.7 (12.3) at first ANC visit to 112.4 (14.1) at delivery. We observed a significant negative quadratic relationship between infant gross motor (GM) function and Hb concentration at first and second ANC visits. Thus, infant GM scores increased sharply with increasing maternal Hb concentration until 90 g/L where increasing GM was mild, and began to decline after 110 g/L. CONCLUSIONS There appears to be an Hb concentration range that may be optimal for GM function of 1-year-old children. This may reflect the importance of physiologic hemodilution, which occurs after the second trimester until 34 weeks of gestation.

Abstract
Acculturation has been shown to positively and negatively affect Latino health. Little research investigates the overlap between acculturation and the different types of relationship violence among Latino youth and most research in this area predominantly involves Mexican-American samples. The current study examined associations between indices of acculturation (language use at home, chosen survey language, and nativity) and relationship physical violence and sexual coercion, both received and delivered, among predominantly Dominican and Puerto Rican adolescents from New York City. From 2006 to 2007, 1,454 adolescents aged 13-21 years in New York City completed an anonymous survey that included the Conflict in Adolescent Relationships Inventory which estimates experiences of physical violence and sexual coercion, both received and delivered, in the previous year. This analysis includes bivariate and multivariate methods to test the associations between language use at home, chosen survey language, and nativity with the different types of relationship violence. Among females, there is a significant association between language use at home and overall level of acculturation with delivering and receiving relationship physical violence; however, we did not find this association in delivering and receiving relationship sexual coercion. We found no association between acculturation and any type of relationship violence among males. Among Latina females, language spoken at home is an indicator of other protective factors of physical relationship violence. Future research in this area should explore the potential protective factors surrounding relationship violence among Latina females of various subgroups using comprehensive measures of acculturation, household composition and family engagement.

Abstract
OBJECTIVE To determine the effect of helminth infection during pregnancy on the cognitive and motor functions of one-year-old children. METHODS Six hundred and thirty five singletons born to pregnant women enrolled before 29 weeks of gestation in a trial comparing two intermittent preventive treatments for malaria were assessed for cognitive and motor functions using the Mullen Scales of Early Learning, in the TOVI study, at twelve months of age in the district of Allada in Benin. Stool samples of pregnant women were collected at recruitment, second antenatal care (ANC) visit (at least one month after recruitment) and just before delivery, and were tested for helminths using the Kato-Katz technique. All pregnant women were administered a total of 600 mg of mebendazole (100 mg two times daily for 3 days) to be taken after the first ANC visit. The intake was not directly observed. RESULTS Prevalence of helminth infection was 11.5%, 7.5% and 3.0% at first ANC visit, second ANC visit and at delivery, respectively. Children of mothers who were infected with hookworms at the first ANC visit had 4.9 (95% CI: 1.3-8.6) lower mean gross motor scores compared to those whose mothers were not infected with hookworms at the first ANC visit, in the adjusted model. Helminth infection at least once during pregnancy was associated with infant cognitive and gross motor functions after adjusting for maternal education, gravidity, child sex, family possessions, and quality of the home stimulation. CONCLUSION Helminth infection during pregnancy is associated with poor cognitive and gross motor outcomes in infants. Measures to prevent helminth infection during pregnancy should be reinforced.
