Women’s and men’s reports of past-year prevalence of intimate partner violence and rape and women’s risk factors for intimate partner violence: A multicountry cross-sectional study in Asia and the Pacific

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

Multi-level modelling of longitudinal child growth data from the Birth-to-Twenty Cohort: a comparison of growth models

Abstract Background: Different structural and non-structural models have been used to describe human growth patterns. However, few studies have compared the fitness of these models in an African transitioning population. Aim: To find model(s) that best describe the growth pattern from birth to early childhood using mixed effect modelling. Subjects and methods: The study compared the fitness of four structural (Berkey-Reed, Count, Jenss-Bayley and the adapted Jenss-Bayley) and two non-structural (2nd and 3rd order Polynomial) models. The models were fitted to physical growth data from an urban African setting from birth to 10 years using a multi-level modelling technique. The goodness-of-fit of the models was examined using median and maximum absolute residuals, Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC). Results: There were variations in how the different models fitted to the data at different measurement occasions. The Jenss-Bayley and the polynomial models did not fit well to growth measurements in the early years, with very high or very low percentage of positive residuals. The Berkey-Reed model fitted consistently well over the study period. Conclusion: The Berkey-Reed model, previously used and fitted well to infancy growth data, has been shown to also fit well beyond infancy into childhood.

Peer violence perpetration and victimization: prevalence, associated factors and pathways among 1752 sixth grade boys and girls in schools in Pakistan.

Background Child peer violence is a global problem and seriously impacts health and education. There are few research studies available in Pakistan, or South Asia. We describe the prevalence of peer violence, associations, and pathways between socio-economic status, school performance, gender attitudes and violence at home. Methods 1752 children were recruited into a cluster randomized controlled trial conducted on 40 fairly homogeneous public schools (20 for girls and 20 for boys), in Hyderabad, Pakistan. This was ranging from 20–65 children per school. All children were interviewed with questionnaires at baseline. Results Few children had no experience of peer violence in the previous 4 weeks (21.7% of girls vs.7% of boys). Some were victims (28.6%, of girls vs. 17.9% of boys), some only perpetrated (3.3% of girls vs. 2.5%) but mostly they perpetrated and were victims (46.4%.of girls vs 72.6%. of boys). The girls’ multivariable models showed that missing the last school day due to work, witnessing her father fight a man in the last month and having more patriarchal gender attitudes were associated with both experiencing violence and perpetration, while, hunger was associated with perpetration only. For boys, missing two or more days of school in the last month, poorer school performance and more patriarchal attitudes were associated with both victimization and perpetration. Witnessing father fight, was associated with peer violence perpetration for boys. These findings are additionally confirmed with structural models. Discussion Peer violence in Pakistan is rooted in poverty and socialization of children, especially at home. A critical question is whether a school-based intervention can empower children to reduce their violence engagement in the context of poverty and social norms supportive of violence. In the political context of Pakistan, reducing all violence is essential and understanding the potential of schools as a platform for intervention is key.

Sharing perspectives and experiences of doctoral fellows in the first cohort of Consortium for Advanced Research Training in Africa: 2011–2014

Background Resolution of public health problems in Africa remains a challenge because of insufficient skilled human resource capacity. The Consortium for Advanced Research Training in Africa (CARTA) was established to enhance capacity in multi-disciplinary health research that will make a positive impact on population health in Africa. Objective The first cohort of the CARTA program describes their perspectives and experiences during the 4 years of fellowship and puts forward suggestions for future progress and direction of research in Africa. Conclusions The model of training as shown by the CARTA program is an effective model of research capacity building in African academic institutions. An expansion of the program is therefore warranted to reach out to more African academics in search of advanced research training.Background Resolution of public health problems in Africa remains a challenge because of insufficient skilled human resource capacity.

The intersection of school corporal punishment and associated factors: Baseline results from a randomized controlled trial in Pakistan

Violence against youth is a global issue; one form of youth victimization is school corporal punishment. We use baseline assessments from a cluster randomized controlled trial to examine the prevalence of school corporal punishment, by gender, and the relationship to levels of peer violence at school, parent corporal punishment, youth food security and youth academic performance and school attendance in Pakistan. Forty homogenous public schools in the urban city of Hyderabad, Pakistan were chosen for randomization into the trial evaluating a youth violence prevention intervention. 1752 6th graders, age 11–14 years, were selected as the target population. Since schools are segregated by gender in Pakistan, data are from interviews in 20 boys’ schools and 20 girls’ schools. Overall, 91.4% of boys and 60.9% of girls reported corporal punishment at school in the previous 4 weeks and 60.3% of boys had been physically punished at home in the past 4 weeks compared to 37.1% of girls. Structural equation modeling revealed one direct pathway for both boys and girls from food insecurity to corporal punishment at school while indirect pathways were mediated by depression, the number of days missed from school and school performance and for boys also by engagement in peer violence. Exposure to corporal punishment in school and from parents differs by gender, but in both boys and girls poverty in the form of food insecurity was an important risk factor, with the result that poorer children are victimized more by adults.

Prevalence and risk factors of intimate partner violence among women in four districts of the central region of Ghana: Baseline findings from a cluster randomised controlled trial

Intimate partner violence (IPV) is a significant global public health problem. Understanding risk factors is crucial for developing prevention programmes. Yet, little evidence exists on population-based prevalence and risk factors for IPV in West Africa. Our objective was to measure both lifetime and past year prevalence of IPV and to determine factors associated with past year physical or sexual IPV experience. This population-based survey involved 2000 randomly selected women aged 18 to 49 years living in 40 localities within four districts of the Central Region of Ghana. Questionnaires were interviewer-administered from February to May 2016. Respondents were currently or ever-partnered, and resident in study area ≥12months preceding the survey. Data collected included: socio-demographics; sexual behavior; mental health and substance use; employment status; 12-month and lifetime experience of violence; household food insecurity; gender norms/attitudes; partner characteristics and childhood trauma. Logistic regression modelling was used to determine factors associated with sexual or physical IPV, adjusting for age and survey design. About 34% of respondents had experienced IPV in the past year, with 21.4% reporting sexual and or physical forms. Past year experience of emotional and economic IPV were 24.6% and 7.4% respectively. Senior high school education or higher was protective of IPV (AOR = 0.51[0.30–0.86]). Depression (AOR = 1.06[1.04–1.08], disability (AOR = 2.30[1.57–3.35]), witnessing abuse of mother (AOR = 2.1.98[1.44–2.72]), experience of childhood sexual abuse (AOR = 1.46[1.07–1.99]), having had multiple sexual partners in past year (AOR = 2.60[1.49–4.53]), control by male partner (AOR = 1.03[1.00–1.06]), male partner alcohol use in past year (AOR = 2.65[2.12–3.31]) and male partner infidelity (AOR = 2.31[1.72–3.09]) were significantly associated with increased odds of past year physical or sexual IPV experience. Male perpetrated IPV remains a significant public health issue in Ghana. Evidence-based interventions targeting women’s mental health, disabilities, exposure to violence in childhood, risky sexual behavior and unequal power in relationships will be critical in reducing IPV in this setting.

Prevalence and risk factors of physical or sexual intimate violence perpetration amongst men in four districts in the central region of Ghana: Baseline findings from a cluster randomised controlled trial

Background Evidence-based interventions are essential in the prevention of violence against women (VAW). An understanding of risk factors for male perpetration of VAW using population-based research is crucial for developing such interventions. This study is a baseline assessment of a two-arm unmatched cluster randomised controlled trial (C-RCT), set up to assess the impact of a Rural Response System (RRS) intervention for preventing violence against women and girls in Ghana. This study aims at assessing past year prevalence and risk factors for sexual or physical intimate partner violence (IPV) perpetration among men. Methods The population-based survey involved 2126 men aged 18 and above living in selected communities in 4 districts in the central region of Ghana. Logistic regression techniques were used to determine risk factors for sexual or physical IPV perpetration. All models adjusted for age of respondent and took into account the study design. Results Half of the men had perpetrated at least one form of violence against their intimate partners in their lifetime while 41% had perpetrated sexual or physical IPV. Majority (93%) of the men had been in relationships in the 12 months preceding the survey, and of these, 23% had perpetrated sexual or physical IPV. Childhood factors associated with sexual or physical IPV included witnessing abuse of mother (aOR:1.40(1.06–1.86)), and neglect (aOR:1.81(1.30–2.50)). Other major risk factors for IPV perpetration were: having multiple partners (aOR:1.76(1.36–2.26)), (involvement in transactional sex (aOR:1.76(1.36–2.26)), substance use (aOR:1.74(1.25–2.43)) and gender inequitable attitudes (aOR:0.94(0.91–0.97)). Conclusion Childhood violence experience and witnessing, risky behaviour (multiple partners, transactional sex, substance use) and gender inequitable attitudes are major risk factors for sexual or physical IPV perpetration. Perpetration of sexual or physical IPV tend to co-occur with non-partner violence and emotional IPV perpetration. Interventions targeting these factors are critical in reducing IPV.
