Health Outcomes in Women with Physical and Sexual Intimate Partner Violence Exposure

This study aims to describe the daily co-occurrence of physical, sexual, and psychological intimate partner violence (IPV) among substance-using, community-based women currently experiencing IPV. A micro-longitudinal study design was used to collect data daily from 49 women for 90 days. On the majority of days (62%), no IPV occurred; 27% of days were characterized by psychological IPV alone, followed by the co-occurrence of psychological and physical IPV (6% of IPV days). Results of person-level analyses showed comparable sized correlations between the proportion of days with physical and sexual IPV and the proportion of days with physical and psychological IPV. However, results of day-level analyses revealed that the association between physical and psychological IPV was much stronger than the association between physical and sexual IPV; Physical IPV was 64 times more likely to occur on days when psychological IPV occurred. Results revealed new information about physical, sexual, and psychological IPV experiences and demonstrate the utility of a micro-longitudinal design among this high risk population. Implications for practice, future research, and the development of preventive interventions are noted, underscoring the importance of psychological IPV and the range of IPV experiences among women.

A social empowerment intervention to prevent intimate partner violence against women in a microfinance scheme in Tanzania: findings from the MAISHA cluster randomised controlled trial

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

BackgroundUnderstanding 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 findingsThis 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.ConclusionsPast-year IPV indicators based on women’s reported experience that were developed to track SDG 5 are probably reasonably reliable but will not always give the same prevalence as may be reported by men. Report validity requires further research. Interviews with men to track past-year nonpartner rape perpetration are feasible and important. The findings suggest a range of factors are associated with past-year physical and/or sexual IPV exposure; of particular interest is the resilience pathway suggested by the structural model, which is highly amenable to intervention and explains why combining economic empowerment of women and gender empowerment/relationship skills training has been successful. This study provides additional rationale for scaling up violence prevention interventions that combine economic and gender empowerment/relationship skills building of women, as well as the value of investing in girls’ education with a view to long-term violence reduction.

Intimate partner violence (IPV) among adolescents is common worldwide, but our understanding of perpetration, gender differences and the role of social-ecological factors remains limited. To explore the prevalence of physical and sexual IPV perpetration and victimisation by gender, and associated risk and protective factors. Young adolescents (N=2 839) from 41 randomly selected public high schools in the Western Cape region of South Africa (SA), participating in the PREPARE study, completed a self-administered questionnaire. The participants' mean age was 13.65 years (standard deviation 1.01), with 19.1% (541/2 839) reporting being victims/survivors of IPV and 13.0% (370/2 839) reporting perpetrating IPV. Girls were less likely to report being a victim/survivor of physical IPV (odds ratio (OR) 0.72; 95% confidence interval (CI) 0.57 - 0.92) and less likely to be a perpetrator of sexual IPV than boys (OR 0.33; 95% CI 0.21 - 0.52). Factors associated with perpetration of physical and sexual IPV were similar and included being a victim/survivor (physical IPV: OR 12.42; 95% CI 8.89 - 17.36, sexual IPV: OR 20.76; 95% CI 11.67 - 36.93), being older (physical IPV: OR 1.26; 95% CI 1.08 - 1.47, sexual IPV: OR 1.36; 95% CI 1.14 - 1.62 ), having lower scores on school connectedness (physical IPV: OR 0.59; 95% CI 0.46 - 0.75, sexual IPV: OR 0.56; 95% CI 0.42 - 0.76) and scoring lower on feelings of school safety (physical IPV: OR 0.66; 95% CI 0.57 - 0.77, sexual IPV: OR 0.50; 95% CI 0.40 - 0.62). Physical and sexual IPV was commonly reported among young adolescents in SA. Further qualitative exploration of the role of reciprocal violence by gender is needed, and the role of 'school climate'-related factors should be taken into account when developing preventive interventions.

When intimate partner violence (IPV) data are collected from only one partner, they are often subject to considerable reporting bias. However, it is not easy to collect such data from couples, and inaccuracies might result in discrepancies, which needs a resolution. We assessed the concordance on reports of lifetime and previous year physical, sexual, and emotional IPV against wives, as reported by both Nepalese wives and husbands. The association of possible risk factors with discordant reporting of IPV was also analyzed. We conducted a cross-sectional study in two areas in Nepal between August and September 2011. We collected data from 717 randomly selected couples on lifetime and previous year experience of physical, sexual, and emotional IPV against wives, as well as their sociodemographic characteristics. We calculated the kappa coefficients and agreement percentage to assess the concordance on wives' reports of IPV victimization and husbands' reports of IPV perpetration. We also performed multiple logistic regressions to identify the factors associated with discordant reporting of IPV among couples. Levels of concordance between wives' and husbands' reports of IPV were significantly low, as indicated by kappa coefficients, ranging from .20 (sexual and emotional IPV) to .24 (physical IPV) in lifetime experience and from .15(sexual IPV) to .18 (physical IPV) in previous year experience. Wives' caste, husbands' age and education, household income, and place of residence were significantly associated with discordance in IPV reports among Nepalese couples. Discordant reporting about IPV is common among Nepalese couples. Collecting information from both partners might be important to obtain more reliable data on IPV in the Nepalese context.

Intimate Partner Violence and Women’s Physical, Mental, and Social Functioning

Prevalence of and factors associated with male perpetration of intimate partner violence: findings from the UN Multi-country Cross-sectional Study on Men and Violence in Asia and the Pacific.

OBJECTIVE:Intimate partner violence (IPV) against women is an important public health problem. In this study, we aimed to investigate the exposure of IPV types, child abuse and decrease in life contentment of married women from high socioeconomic status in Turkey.METHODS:Data were collected using an online/written questionnaire and Contentment with Life Scale. The questionnaire included definitions of physical, emotional, economic and sexual IPV and asked how many times they experienced these types of abuse.RESULTS:We found that physical, emotional, economic and sexual IPV exposure were 19%, 45.2%, 12.5%, and 6%, respectively, which suggest that IPV types were common in this group, too. Physical child abuse was higher among physical and emotional IPV victims (p=0004, p=0.02, respectively), while emotional child abuse was higher only among physical IPV victims (p=0.01). On the other hand, exposure to economic and sexual IPV was not related to any type of child abuse in this sample (p>0.05). Physical and economic IPV victims were statistically older (p=0.004, p<0.001, respectively), married for longer time (p<0.001 for both) and had relatively lower education level (p<0.001 for both), while sexual IPV victims had lower education level than non-victims (p=0.03). We demonstrated that physical-emotional and sexual intramarital IPV significantly reduce the women’s contentment with life scores when compared with non-victims (p=0.02, p<0.001 and p=0.03, respectively).CONCLUSION:IPV exposure is also severe among married women with high socioeconomic levels and is associated with child abuse in the family and a decrease in life contentment. Lengthened education period among women with similar socioeconomic levels may be an additional protective factor for IPV by delaying the age of marriage and increasing the individual income.

Evidence suggests that gendered social norms play a significant role in the increased prevalence of intimate partner violence (IPV) at both individual and household levels. While some relationships may exhibit abusive dynamics from the beginning, IPV frequently starts with subtle non-physical behaviours, such as threats, control, rejection and gaslighting among others before escalating into more severe forms of abuse over time. We use the DHS 2016 survey data from Uganda to examine whether emotional abuse by a woman's partner mediates the association between norms regarding wife beating and instances of self-reported physical or sexual IPV, analysed through structural equation modelling. We also explore the impact of alcohol consumption by the victim's partner. Results: The prevalence of emotional abuse, physical and sexual IPV in the 12 months preceding the survey was 29.3%, 21.9% and 16.4% respectively. The majority (65.6%) of those who reported physical or sexual IPV also reported experiencing emotional abuse. Women residing in neighbourhoods with higher scores on norms indicating greater acceptance towards wife beating had higher odds of experiencing physical (OR = 5.94; 95% CI [2.99, 11.79]) or sexual IPV (2.71; [1.36, 5.39]) compared to neighbourhoods with lower scores. Mediation analysis showed that emotional abuse mediated the association; there was a direct positive association between neighbourhood norms and physical IPV (4.82; [2.15, 10.79]) but weak evidence for sexual IPV (1.87; [0.95, 3.68]). The estimates remained largely unchanged in the presence of alcohol use. Independently, neighbourhood norms associated with physical IPV (2.48; [1.28, 4.83]) and sexual IPV (2.27; [1.21, 4.28]). Emotional abuse as a precursor to physical and sexual abuse could have implications for IPV programming and interventions. In addition to efforts that target changing negative social norms, interventions might benefit from strategies to easily identify emotional abuse.

Violence against women remains a significant public health problem globally. The majority of longitudinal studies documenting the negative impact of intimate partner violence (IPV) on the mental health of women come from high-income countries. The aim of this study was to investigate the longitudinal association between emotional, physical, or sexual IPV and depression symptoms among South African women in a prospective cohort study. Participants were 981 South African women enrolled in the Drakenstein Child Health Study-a cohort study investigating the early life determinants of child health. Interview data from four time-points (antenatal care visit, 6 months, 12 months, and 18 months postpartum) were included. The primary independent variable was self-reported emotional, physical, and sexual IPV in the past 12 months. Depressive symptoms were assessed at each time-point with the Edinburgh Postnatal Depression Scale (EPDS); a cutoff score of ⩾13 was used to define significant depression symptoms. We used pooled-multivariable logistic regression models to determine associations between the three different forms of IPV and significant depression symptoms while adjusting for time-fixed and time-updated covariates. The mean age of the sample at antenatal care visit was 27 years (standard deviation = 6.0). In the adjusted model including all forms of IPV and adjusting for sociodemographic and clinical characteristics, substance use, and childhood trauma, emotional (adjusted odds ratio [aOR] =1.55, 95% confidence interval (CI): [1.02, 2.34]; p = .039)] and sexual (aOR = 2.02, 95% CI: [1.10, 3.72]; p < .001) IPV were significantly associated with significant depression symptoms. The relationship between physical IPV and significant depression symptoms was not statistically significant (aOR = 0.68, 95% CI: [0.44, 1.05]; p = .485). Our study confirms findings from high-income countries of the association between IPV and depressive symptoms among women in South Africa. Routine screening for IPV, including emotional IPV and intervention programs for IPV among women, is needed in South Africa.

Intimate partner violence (IPV) perpetration is common among men who use substances. Substance use is a contributing factor for IPV perpetration. This cross-sectional study determined lifetime prevalence and factors associated with ever perpetrating IPV by men receiving substance use treatment in Brazil (n = 281) and England (n = 223). IPV, adverse childhood experiences, attitudes towards gender relations and roles, current health state, substance use, depressive symptoms and anger expression were assessed. Logistic regression determined factors associated with ever perpetrating any (emotional, physical and/or sexual) IPV. Multinomial logistic regression determined factors associated with ever perpetrating different types of IPV. 74.6% (373/500) reported ever perpetrating IPV: 16.5% (82/498) emotional IPV only, 46.4% (231/498) physical IPV (with/without emotional IPV) and 11.6% (58/498) sexual IPV (with/without emotional and/or physical IPV). Higher anger expression, higher depressive symptoms, fighting physically with another man in the past year (Brazil only), experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score (England only) predicted ever perpetrating IPV. Compared to never perpetrating any IPV, anger expression was associated with emotional and physical IPV perpetration; fighting physically with another man in the past year was associated with physical IPV perpetration and experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score were associated with both physical and sexual IPV perpetration. Integrated interventions that address IPV and substance use delivered in substance use treatment could improve outcomes for perpetrators and victims.[Gilchrist G, Radcliffe P, Noto AR, d'Oliveira AFPL. The prevalence and factors associated with ever perpetrating intimate partner violence by men receiving substance use treatment in Brazil and England: A cross-cultural comparison. Drug Alcohol Rev 2017;36:34-51].

Using data from 8,320 husbands'self reports for the 2006 Urban Health Survey, this article examines the prevalence of physical and sexual intimate partner violence (IPV) perpetrated by husbands against their wives in Bangladesh and identifies risk markers associated with such violence. Of the men included in the sample for this study, 55 percent reported perpetrating physical IPV against their wives at some point in their married lives, 23 percent reported perpetrating physical IPV in the past year, 20 percent reported ever perpetrating sexual IPV, and 60 percent reported ever perpetrating physical or sexual IPV. Bivariate analyses revealed that men residing in slums had a greater likelihood than those residing in nonslum areas and in district municipalities of perpetrating lifetime and past-year physical IPV, and any lifetime (physical or sexual) IPV. Lifetime sexual IPV prevalence, by contrast, was highest in district municipalities (26 percent), followed by slum (20 percent) and nonslum (17 percent) areas. Net of other factors, low socioeconomic levels were associated with men's increased likelihood of perpetrating IPV. Alcohol and drug use, sexually transmitted disease infection, poor mental health, and holding attitudes supportive of wife beating were predictive of IPV perpetration. These results suggest that IPV-prevention programs targeting men should consider spousal abuse, substance use, and sexual risk behaviors as social and public health problems and should also consider the sociocultural context within which men who abuse their partners are embedded.

Little research has assessed the impact of emotional intimate partner violence (IPV) and economic IPV on women’s mental health. Using cross-sectional data from the Stepping Stones and Creating Futures intervention trial baseline, in eThekwini Municipality, South Africa we assess three questions. First, whether emotional IPV and economic IPV make independent contributions to mental health outcomes; second what matters, severity, variety, or absolute experience? and third, are some items more important in driving mental health impacts than others? We assess associations between past 12-month emotional IPV, past 12-month economic IPV, and past week depressive symptoms and past four-week suicidal ideation. We describe the prevalence of each mental health outcome by individual items, including never/ever and frequency, and combined emotional IPV, and economic IPV, reporting depression scores and percentage of suicidal ideation and 95% confidence intervals (CI). Second, we created four-level categorical variables for combinations of emotional, economic, sexual and physical IPV, and present its frequency, and the mean/% and 95% CI for depression symptomatology and suicidal ideation. 680 women (aged 18–30) were enrolled. High levels of past year emotional IPV, economic IPV were reported. 45.3% reported clinically relevant symptoms of depression, and 30.0% past four-week suicidal ideation. All measures of emotional IPV and economic IPV showed a consistent positive correlation with CESD scores, and suicidal ideation. For all four-level categorical constructs the highest depression scores, and prevalence of suicidal ideation, were for combinations of emotional IPV or economic IPV with physical and/or sexual IPV. For depression in 17/18 combinations this was significantly different compared to women reporting no IPV. For suicidal ideation this was significant in 6/18 combinations all related to economic IPV. Emotional IPV and economic IPV have independent associations with women’s mental health, beyond physical IPV and sexual IPV, and also have distinct patterns between each other.Trial registrationNCT03022370.

OBJECTIVEWe sought to estimate the association between intimate partner violence, a prevalent psychosocial stressor, and the incidence of type 2 diabetes in women.RESEARCH DESIGN AND METHODSIn 2001, 68,376 Nurses’ Health Study II participants answered questions on physical, sexual, and psychological intimate partner violence in adulthood (age ≥18 years) and reported the years in which any abuse occurred. We used Cox proportional hazards models to estimate the associations between intimate partner violence exposures and incidence of type 2 diabetes from 2001 to 2007. We also estimated effects of duration and time since intimate partner violence on type 2 diabetes incidence.RESULTSOf 68,376 respondents, 64,732 met inclusion criteria at the 2001 baseline; of these, 23% reported lifetime physical intimate partner violence, 11% reported lifetime sexual intimate partner violence, and 8% reported moderate and <2% reported severe psychological intimate partner violence. Hazard ratios (HRs) and 95% CIs for type 2 diabetes, adjusted for potential confounders, were 1.18 (1.00–1.39) and 1.08 (0.86–1.35) for more than one lifetime episode of physical and sexual intimate partner violence, respectively, and 1.78 (1.21–2.61) for severe psychological abuse. Addition of updated BMI and other diabetes risk factors reduced the physical intimate partner violence HR to 1.12 (0.94–1.33) and the psychological intimate partner violence HR to 1.61 (1.09–2.38).CONCLUSIONSPhysical intimate partner violence is modestly associated with incidence of type 2 diabetes in this population. Severe psychological violence may substantially increase type 2 diabetes risk.
