Gender inequality increases women's risk of hiv infection in Moshi, Tanzania

This study examined the hypothesis that multiple dimensions of gender inequality increase women's risk for HIV infection using a population-based survey of 1418 women aged 20 to 44 in Moshi, Tanzania. Three forms of HIV exposures were assessed reflecting gender power imbalance: economic exposures (age difference between partners and partner's contributions to children's expenses), physical exposures (coerced first sex and intimate partner violence) and social exposures (ever had problems conceiving). Behavioural risk factors included number of sexual partners for women in the last three years, partner had other wives or girlfriends, non-use of condom and alcohol use at least once a week in the last 12 months. Multivariate logistic regression analysis showed that a woman had a significantly elevated risk for HIV if she had a partner more than 10 years older (OR=2.5), her partner made low financial contributions to children's expenses (OR=1.7), or she experienced coerced first sex before age 18 years (OR=2.0) even after taking into account the effects of risk behaviour factors. The association between ever had problem conceiving and HIV infection was explained away by risk behaviour factors. The findings lend support to the hypothesis that economic deprivation and experience of sexual violence increase women's vulnerability to HIV, providing further evidence for extending the behavioural approach to HIV interventions to incorporate women's economic empowerment, elimination of gender-based violence and promotion of changing attitudes and behaviours among men.     

Contraception use and associations with intimate partner violence among women in Bangladesh

This study examines the association between contraception use and intimate partner violence (IPV) among women of reproductive age in Bangladesh. The observational study of 10,996 women used the chi-squared test and logistic regressions to assess the associations. Almost 80% of all respondents had used contraceptives at some point in their lives. About half of the respondents (48%) were victims of physical violence, while 11% experienced sexual abuse from their husbands. Urban residents, higher educated women and women aged 20-44 were more likely to use contraceptives than their peers in rural areas, those with lower education and those in their late forties (45-49 years). Women exposed to physical violence were almost two times (OR 1.93, CI 1.55-2.41) more likely to use contraceptives compared with their non-abused peers. Sexual abuse had no significant association with contraceptive use. Physical violence is a predictor for higher levels of contraceptive use among women in Bangladesh. The findings emphasize the importance of screening for IPV at health care centres. The differences in urban and rural contraceptive use and IPV exposure identified by the study have policy implications for service delivery and planning.     

Quality of care and contraceptive pill discontinuation in rural Egypt

Indicators of family planning service access and quality were generated using the Egypt DHS-I (1988) and the Egypt Service Availability Survey (1989), and linked to episodes of contraceptive pill use. Multilevel analysis was used to ascertain whether or not these access and quality indicators influence the continuation of pill use, net of women's socioeconomic, demographic and motivational characteristics. A model with random components at the cluster and women levels was fitted for all reasons of discontinuation, except desire for pregnancy, at 24 months of use. Net of women's background characteristics, the results show that facilities with smaller numbers of health personnel trained in family planning, a lack of access to facilities with female doctors and a lack of range of available methods are associated with a high risk of discontinuation of pill use for all reasons except desire for pregnancy.     

Intimate Partner Violence,Relationship Power Inequity and the Role of Sexual and Social Risk Factors in the Production of Violence among Young Women Who Have Multiple Sexual Partners in a Peri-Urban Setting in South Africa

Introduction

This paper aims to assess the extent and correlates of intimate partner violence (IPV), explore relationship power inequity and the role of sexual and social risk factors in the production of violence among young women aged 16–24 reporting more than one partner in the past three months in a peri-urban setting in the Western Cape, South Africa. Recent estimates suggest that every six hours a woman is killed by an intimate partner in South Africa, making IPV a leading public health problem in the country. While there is mounting evidence that levels of IPV are high in peri-urban settings in South Africa, not much is known about how it manifests among women who engage in concomitantly high HIV risk behaviours such as multiple sexual partnering, transactional sex and age mixing. We know even less about how such women negotiate power and control if exposed to violence in such sexual networks.

Methods

Two hundred and fifty nine women with multiple sexual partners, residing in a predominantly Black peri-urban community in the Western Cape, South Africa, were recruited into a bio-behavioural survey using Respondent Driven Sampling (RDS). After the survey, focus group discussions and individual interviews were conducted among young women and men to understand the underlying factors informing their risk behaviours and experiences of violence.

Findings

86% of the young women experienced IPV in the past 12 months. Sexual IPV was significantly correlated with sex with a man who was 5 years or older than the index female partner (OR 1.7, 95% CI 1.0–3.2) and transactional sex with most recent casual partner (OR 2.1, 95% CI 1.1–3.8). Predictably, women experienced high levels of relationship power inequity. However, they also identified areas in their controlling relationships where they shared decision making power.

Discussion

Levels of IPV among young women with multiple sexual partners were much higher than what is reported among women in the general population and shown to be associated with sexual risk taking. Interventions targeting IPV need to address sexual risk taking as it heightens vulnerability to violence.     

Sexual behaviour, contraceptive practice and knowledge of AIDS of Oxford University students

In 1987, a questionnaire was sent to 584 undergraduate students at Oxford University requesting information about their sexual behavior and contraceptive practices as well as the impact of acquired immunodeficiency syndrome (AIDS) on both these factors. Of the 374 responders, 65% of the women and 62% of the men had experienced sexual intercourse; 1st intercourse had occurred at ages 16-20 years for 89% of the experienced women and 83% of the men. For 36% of women and 37% of men intercourse had been with 1 partner only, for 28% of women and 27% of men with 2-3 partners, and for 36% of both men and women with more than 3 partners. 27% of the women reported no contraceptive was used at the time of 1st intercourse. During the 4 weeks preceding completion of the questionnaire, 15% of sexually active female undergraduates reported not using adequate contraception. Users during this period selected the pill (64%), condom (19%), IUD or diaphragm (9%), or withdrawal/rhythm (8%). General knowledge about AIDS was highly accurate among these students. Most students considered themselves to be at lower risk of contracting AIDS than others of their age and sex. Of the 78% of students describing themselves as at lower than average risk, 14% had had intercourse with more than 3 partners, while 50% of the 20% of students who ranked themselves as at average risk had this number of partners. Only 2% placed themselves as at above average risk, and 65% of these students had had more than 3 sexual partners. Of students who were sexually active, 35% of the females and 44% of the males indicated they are now more likely to use a condom because of fear of AIDS. 49% of the females and 30% of the males indicated they had, or would have, fewer sexual partners because of the AIDS risk. However, there was no association between increased likelihood of condom use and the total number of sexual partners and having had intercourse with someone in a high-risk group for AIDS (prostitutes). Overall, however, these findings suggest that the AIDS threat is producing reductions in high-risk behaviors.     

Analysing the relationship between family planning workers' contact and contraceptive switching in rural Bangladesh using multilevel modelling

With a population of over 131 million and a fertility rate of 29.9 per 1000, population growth constitutes a primary threat to continued economic growth and development in Bangladesh. One strategy that has been used to cease further increases in fertility in Bangladesh involves using family planning outreach workers who travel throughout rural and urban areas educating women regarding contraceptive alternatives. This study uses a longitudinal database to assess the impact of family planning outreach workers' contact upon contraceptive switching and upon the risk of an unintended pregnancy. Using longitudinal data on contraceptive use from the Operations Research Project (ORP) of the International Centre for Diarrhoeal Disease Research (ICDDR,B) in Bangladesh, multiple decrement life table analysis and multilevel, discrete-time competing risk hazards models were used to estimate the cumulative probabilities of switching to an alternative form of contraceptive use after a woman engaged in a discussion with an outreach worker. After controlling for the effects of socio-demographic and economic characteristics, the analysis revealed that family planning outreach workers' contact with women significantly decreases the risk of transitioning to the non-use of contraceptives. This contact also reduces the risk of an unintended pregnancy. Family planning workers' contact with women is associated with the increased risk of a woman switching from one modern method to another modern method. The study results indicate that side-effects and other method-related reasons are the two primary reasons for contraceptive discontinuation in rural Bangladesh.     

Patterns of contraceptive use in Australia: analysis of the 2001 National Health Survey

The purpose of this paper is to review the patterns of contraceptive use in Australia, using data from a nationally representative sample of 5872 women aged 18 to 49. This survey was conducted by the Australian Bureau of Statistics in 2001 as part of the National Health Survey. Results of the analysis indicate that the oral contraceptive pill and condom were the two most frequently used methods. More than 76% of the respondents reported having ever used the pill. Over 23% of women were currently using condoms; of these 80% of the condom users used them for contraception - this included 36% who used condoms for both protection against infection and for contraception - and the remainder used them only for protection. Withdrawal was the third most popular non-surgical method up to age 40. Few women used IUDs, injections or diaphragms. Just over 3% of the respondents were using natural methods with the highest rate reported among those in their 30s. The 'morning-after pill' was reported mostly by women aged 18-24; however, there was no evidence to suggest that it was being used as a primary method of birth control. Contraceptive use declined in older women who turned to sterilization for themselves and/or their partners. Use of the contraceptive pill was somewhat higher among better-educated women, but lower among less-educated women and those from non-English-speaking backgrounds.     

Unmet Need for Family Planning,Contraceptive Failure,and Unintended Pregnancy among HIV-Infected and HIV-Uninfected Women in Zimbabwe

Background

Prevention of unintended pregnancies among women living with HIV infection is a strategy recommended by the World Health Organization for prevention of mother-to-child transmission of HIV (PMTCT). We assessed pregnancy intentions and contraceptive use among HIV-positive and HIV-negative women with a recent pregnancy in Zimbabwe.

Methods

We analyzed baseline data from the evaluation of Zimbabwe’s Accelerated National PMTCT Program. Eligible women were randomly sampled from the catchment areas of 157 health facilities offering PMTCT services in five provinces. Eligible women were ≥16 years old and mothers of infants (alive or deceased) born 9 to 18 months prior to the interview. Participants were interviewed about their HIV status, intendedness of the birth, and contraceptive use.

Results

Of 8,797 women, the mean age was 26.7 years, 92.8% were married or had a regular sexual partner, and they had an average of 2.7 lifetime births. Overall, 3,090 (35.1%) reported that their births were unintended; of these women, 1,477 (47.8%) and 1,613 (52.2%) were and were not using a contraceptive method prior to learning that they were pregnant, respectively. Twelve percent of women reported that they were HIV-positive at the time of the survey; women who reported that they were HIV-infected were significantly more likely to report that their pregnancy was unintended compared to women who reported that they were HIV-uninfected (44.9% vs. 33.8%, p<0.01). After adjustment for covariates, among women with unintended births, there was no association between self-reported HIV status and lack of contraception use prior to pregnancy.

Conclusions

Unmet need for family planning and contraceptive failure contribute to unintended pregnancies among women in Zimbabwe. Both HIV-infected and HIV-uninfected women reported unintended pregnancies despite intending to avoid or delay pregnancy, highlighting the need for effective contraceptive methods that align with pregnancy intentions.     

HIV prevention in high-risk women in South Africa: condom use and the need for change

Introduction

Young women are at disproportionate risk of HIV infection in South Africa. Understanding risk behaviors and factors associated with ability to negotiate safe sex and condom use is likely to be key in curbing the spread of HIV. Traditionally prevention efforts have focused on creating behavioral changes by increasing knowledge about HIV/AIDS.

Methods

This was a cross-sectional analysis from a prospective observational cohort study of 245 women at a high-risk of HIV infection in KwaZulu-Natal, South Africa.

Results

Participants demonstrated a high level of HIV/AIDS knowledge. Overall, 60.3% of participants reported condom use. Reported condom use at last sexual encounter varied slightly by partner type (57.0% with steady versus 64.4% with casual partners), and self-perceived ability to choose to use a condom was significantly lower with steady partners compared to casual partners (p<0.01). In multivariate analysis, women who had high school education were more likely to use condoms at their last sex encounter compared to those with only primary school education (RR of 1.36 (95% Confidence Interval (CI) 1.06–1.75) and 1.46 (95% CI 1.13–1.88) for grades 8–10 and 11–12, respectively). Those who used condoms as a contraceptive method were twice as likely to use condoms compared to women who did not report using them as a contraceptive method. Greater perceived ability to choose to use condoms was associated with higher self-reported condom use at last encounter, irrespective of partner type (RR = 2.65 (95% CI 2.15–32.5).

Discussion

Self-perceived ability to use condoms, level of formal education and condom use as a contraceptive were all significantly associated with self-reported condom use at last sexual encounter. These findings suggest that that gender inequality and access to formal education, as opposed to lack of HIV/AIDS knowledge, prevent safer sexual practices in South Africa.     

Effects of partner conception risk phase on male perception of dominance in faces

Several studies have suggested that women may prefer to engage in extra-pair copulations with males who appear dominant and to do so near ovulation. While there is some evidence that males are more jealous of dominant rivals and more proprietary when their partners are near ovulation, there is none that suggests the existence of counterstrategic perceptual shifts that mirror those seen in women. We provide such evidence here. Composites of male faces that were either high or low in rated dominance were presented to male participants who provided ratings of dominance. A three-way interaction between stimulus-face dominance, partner conception risk phase, and partner oral contraceptive use was found; men whose partners did not use an oral contraceptive and were in the high conception risk phase of their cycle displayed increased dominance ratings of high-dominance male faces. We conclude that males have evolved counterstrategies to deal with female infidelity that include an overattribution of dominance to those rivals most likely to present a threat at times when that threat is greatest. This overattribution is likely to lead to increases in jealousy and mate-retention behaviors.     

Use of the oral contraceptive pill by Austrian adolescents with emphasis on the age of onset,side effects,compliance and lifestyle

The present study investigated the use of the oral contraceptive pill in 880 Austrian high school girls. All participants filled in a questionnaire on lifestyle and menarche. Furthermore, subjects on the pill were asked about their preparation, age at first use, reasons why they take it, side effects and oral contraceptive compliance. All 139 subjects on the pill used low dose monophasic preparations. The girls started the pill at a mean age of 16.0 +/- 0.9 years for contraceptive and therapeutic reasons. The most commonly noted side effects were weight gain, an increase in breast size, fatigue and depression. The results also indicate that most users comply sufficiently. Regarding lifestyle, it can be stated that there is a correlation between the use of the pill and smoking, the frequency of consuming alcoholic drinks and being physically active.     

Epidemiological features of HIV infection among pregnant women in Makurdi, Benue State, Nigeria

Women in Benue State have for years had the highest HIV rate in the country, but because the sentinel surveys are anonymized and unlinked, not much is known about the socio-demographic, behavioural and other risk factors that predispose these women to the disease. The HIV/AIDS epidemic in Nigeria does not appear to be a single epidemic but rather multiple epidemics of varying magnitude and trends. This cross-sectional study was therefore carried out to identify the risk factors for HIV/AIDS among these women. A total of 404 consecutive consenting mothers enrolled at the booking clinic were followed up until delivery of their babies. They were interviewed using a semi-structured questionnaire and tested for HIV infection using an ELISA-based kit after obtaining informed consent. Mean age of the mothers was 26+/-6.1 years, 94.8% were married while 50.5% had at least secondary level education. Sixty-one (15.1%) mothers were HIV positive with mothers aged 15-24 years being responsible for 50.8% of all infection. Following bivariate analysis, being single, having a partner with low level of formal education, living in a rural location, being in a polygamous/multiple partner union, being a higher order polygamous wife, being married more than once and reporting a history of a sexually transmitted infection were significantly associated with HIV infection. Monogamous women who lived apart from their partners and women who had ever had blood transfusion were also more likely to be HIV positive. Following multivariate logistic regression, a young age of 15-24 years (multivariate OR=3.3, 95 % CI=1.2-8.4, p=0.02); ever had other STIs (OR=1.6, 95% CI 1.1-2.3, p=0.009); no formal maternal education (OR=0.6, 95% CI 0.4-0.9, p=0.021) and having one lifetime sexual partner (OR=0.4, 95% CI 0.3-0.5, p<0.00001) were significantly associated with HIV infection in the study population. Appropriate interventions must be directed at young people and should include STI control and abstinence education. Blood safety must be ensured as well as a general improvement in the level of formal and health education in this community.     

Hormonal contraceptive use and mate retention behavior in women and their male partners

Female hormonal contraceptive use has been associated with a variety of physical and psychological side effects. Women who use hormonal contraceptives report more intense affective responses to partner infidelity and greater overall sexual jealousy than women not using hormonal contraceptives. Recently, researchers have found that using hormonal contraceptives with higher levels of synthetic estradiol, but not progestin, is associated with significantly higher levels of self-reported jealousy in women. Here, we extend these findings by examining the relationship between mate retention behavior in heterosexual women and their male partners and women's use of hormonal contraceptives. We find that women using hormonal contraceptives report more frequent use of mate retention tactics, specifically behaviors directed toward their partners (i.e., intersexual manipulations). Men partnered with women using hormonal contraceptives also report more frequent mate retention behavior, although this relationship may be confounded by relationship satisfaction. Additionally, among women using hormonal contraceptives, the dose of synthetic estradiol, but not of synthetic progesterone, positively predicts mate retention behavior frequency. These findings demonstrate how hormonal contraceptive use may influence behavior that directly affects the quality of romantic relationships as perceived by both female and male partners.     

Determinants of pill failure in rural Bangladesh

The pill is the most popular family planning method in Bangladesh. However, the failure rate of this method in Matlab, a typical rural area, has been found to be very high. It is estimated that with the current level of failure of the pill and other temporary contraceptives in Matlab, it is unlikely that fertility in Bangladesh will come down to replacement level without a change in contraceptive method mix. It is, therefore, important to know the reasons for the high failure in pill use. Data for this study came from a case-control study in Matlab. A pill failure was considered a case, and no-failure was considered a control. The study included 167 cases and 167 controls. In addition, five focus group discussions were conducted to supplement the data collected from the cases and controls to gain a deeper understanding of pill failure. Results of the analysis of both quantitative and qualitative data suggested that the following were the risk factors for pill failure: no mobility of women, poor knowledge of women about the effectiveness and consequences of drop-out from pill use, weak confidence in the pill, a gap between the use of subsequence pill cycles, delay in starting the pill after menstruation for the first use, not taking any measures consistently for missing the pill, and not following the arrow sign given on the pill cycle. Extensive training of field workers and pill users, covering the reasons for pill failure identified in this study and strong supervision of the work of field workers, is likely to reduce the rate of pill failure in Bangladesh. Also, information, education and communication services for users, and management of side-effects, may be helpful in reducing pill failure.     

The Contribution of Emotional Partners to Sexual Risk Taking and Violence among Female Sex Workers in Mombasa,Kenya: A Cohort Study

Objectives

To assess sexual risk-taking of female sex workers (FSWs) with emotional partners (boyfriends and husbands), compared to regular and casual clients. Experiences of violence and the degree of relationship control that FSWs have with emotional partners are also described.

Design

Cohort study with quarterly follow-up visit over 12-months.

Methods

Four hundred HIV-uninfected FSWs older than 16 years were recruited from their homes and guesthouses in Mombasa, Kenya. A structured questionnaire assessed participant characteristics and study outcomes at each visit, and women received risk-reduction counselling, male and female condoms, and HIV testing.

Results

Four or more unprotected sex acts in the past week were reported by 21.3% of women during sex with emotional partners, compared to 5.8% with regular and 4.8% with casual clients (P<0.001). Total number of unprotected sex acts per week was 5–6-fold higher with emotional partners (603 acts with 259 partners) than with regular or casual clients (125 acts with 456, and 98 acts with 632 clients, respectively; P<0.001). Mostly, perceptions of “trust” underscored unprotected sex with emotional partners. Low control over these relationships, common to many women (36.9%), was linked with higher partner numbers, inconsistent condom use, and being physically forced to have sex by their emotional partners. Half experienced sexual or physical violence in the past year, similarly associated with partner numbers and inconsistent condom use.

Conclusions

High-risk sexual behaviour, low control and frequent violence in relationships with emotional partners heighten FSWs'' vulnerability and high HIV risk, requiring targeted interventions that also encompass emotional partners.     

Side effects and discontinuation of oral contraceptive use in southern Brazil

Oral contraceptives have many advantages, but sometimes also have side effects which can cause users to switch appropriately or inappropriately to less effective methods or abandon contraception. In Brazil, 2/3 of married women of childbearing age were using contraception in 1981, and 1/2 of these were using orals. Contraceptive behavior following reported side effects in users of oral contraceptives in Southern Brazil is examined in this study, in relation to diverse factors. Among 2904 currently-married women, aged 15-44, almost 75% reported that they had used the pill at some time, and of these, 45.6% were still doing so. Data on perceived side effects were gathered for all women. There was no independent medical evaluation of the effects, so the data did not necessarily represent actual prevalence of pill related problems. Women who reported problems with the pill were less likely to be current users (25%) than women who did not (65%). However, overall contraceptive prevalence was about the same in both groups (66.2% and 67.0% respectively), indicating that women who stop using oral contraceptives usually switch to another method. However, they are more likely to be using traditional methods than women in the general population, especially if they want more children. Termination of pill use varies little according to the type of problem reported. Women with problems who sought medical attention were more likely to stop using the pill, and 82.4% of women advised to stop by their physician did so, but the major factor affecting discontinuation was the reported experience of a problem. The most frequently reported problems were headaches (38.1%), nausea (34.1%), nervousness (27.9%), and vertigo (18.3%). Physician intervention should help to avoid women's abandoning oral contraceptives unnecessarily.     

Prevalence of and risk factors associated with alcohol abuse in Moshi, northern Tanzania

This study aimed to assess the prevalence of and risk factors associated with alcohol abuse among women and men in Moshi in northern Tanzania. Alcohol abuse was measured by a CAGE score of 2-4, versus 0-1 for no alcohol abuse (Ewing, 1984). Crude and adjusted logistic regression models determined odds ratios (OR) and 95% confidence intervals (95% CI) of alcohol abuse by characteristics of, respectively, women with partners (n=1200), women without partners (n=614) and men (n=788) (women's partners). Prevalence of alcohol abuse was 7.0% (95% CI: 5.6-8.4) among women with partners, 9.3% (95% CI: 7.0-11.6) among women without partners, and more than double among men at 22.8% (95% CI: 19.9-25.8). In general, Christians had higher alcohol abuse than Muslims or other religions, as did Chagga men compared with men of other ethnic groups. Other socio-demographic characteristics, such as education or income, were not significant. Sexual behaviours were significant predictors of alcohol abuse. For example, women without partners who reported more than two partners in the last year had higher alcohol abuse compared with women reporting no partners (OR=8.75; 95% CI: 2.37-32.31), as did men reporting it is 'OK to hit a partner' for any reason (OR=1.79; 95% CI: 1.16-2.77) compared with men who did not. HIV-1 infection was not significantly associated with alcohol abuse by women or men. The Christian Church in Moshi should consider raising awareness about the harmful effects of high alcohol use among its adherents. Comprehensive programmes focusing on reducing number of partners and alcohol use, particularly by men, are needed in this community.     

Physical violence against intimate partners and related exposures to violence among South African men

Background

Despite high rates of intimate partner violence in South Africa, there have been no national studies of men''s perpetration of violence against female partners.

Methods

We analyzed data from the South Africa Stress and Health Study, a cross-sectional, nationally representative study, specifically examining data for men who had ever been married or had ever cohabited with a female partner. We calculated the prevalence of physical violence against intimate female partners and used logistic regression to examine associations with physical abuse during childhood and exposure to parental and community violence.

Results

A total of 834 male participants in the South Africa Stress and Health Study met the study criteria. Of these, 27.5% reported using physical violence against their current or most recent female partner during their current or most recent marriage or cohabiting relationship. Crude odds ratios (ORs) and 95% confidence intervals (CIs) indicated significant associations between perpetration of violence against an intimate partner and witnessing parental violence (OR 3.91, 95% CI 2.66–5.73) or experiencing physical abuse during childhood (OR 3.24, 95% CI 2.27–4.63), but not exposure to community violence (OR 1.29, 95% CI 0.88–1.88). The 2 significant associations persisted in adjusted analyses: OR 3.22 (95% CI 1.94–5.33) for witnessing parental violence and OR 1.73 (95% CI 1.07–2.79) for experiencing physical abuse during childhood.

Interpretation

We found a high prevalence of physical violence perpetrated by men against their intimate partners. Men who experienced physical abuse during childhood or were exposed to parental violence were at the greatest risk.Most research about men''s perpetration of violence against female intimate partners has concentrated on elucidating the factors that put women at risk for experiencing such violence and identifying the related service needs. Less work has been done to investigate the factors affecting men''s risk of perpetrating violence against women. Such work is needed to inform development of empirically based public health programs to reduce men''s use of such violence. Intimate partner violence is of pandemic proportions, with global estimates indicating that 15% to 75% of women have experienced such abuse.^1,2 Such violence may confer grave health consequences, including transmission of HIV/AIDS.³The overwhelming majority of research on violence against intimate partners perpetrated by men has been conducted in Western countries, with the focus on men at high risk for such activity (e.g., prisoners, people enrolled in intervention programs for batterers).^4,5 This work has highlighted the importance of exposure to violence early in life (e.g., witnessing parental violence, experiencing child abuse) in predicting perpetration of violence against a partner during adulthood.⁶ Recently, the potential relations between community violence and men''s perpetration of violence against intimate partners have also been examined.⁷Fewer studies have been done in developing nations, but several notable investigations have recently assessed men''s perpetration of violence against intimate partners in South Africa, specifically in Eastern Cape and Cape Town. Two of these studies have indicated high rates of violence against intimate partners: 31.8% in Eastern Cape⁸ and 42.3% in Cape Town.⁹ The extent to which these findings reflect national rates is unknown. Furthermore, work with both men and women in South Africa has demonstrated strong relations between violence (men''s perpetration and women''s victimization) and higher rates of sexually risky behaviours.^3,8 Associations between women''s experience as victims of intimate partner violence and HIV infection have also been documented.³ These data strongly suggest that men''s perpetration of violence against intimate partners is common in South Africa and that it may play an important role in this nation''s HIV epidemic,^3,8 which currently ranks highest in the world with respect to the number of people living with HIV.¹⁰In the study reported here, we sought to build upon prior work by using a national sample of South African men to examine the prevalence of physical violence perpetrated by men against their female intimate partners and potential violence-related risk factors (i.e., exposure to parental violence, experience of abuse in childhood and exposure to community violence).     

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

BackgroundIntimate partner violence (IPV) is an important global public health problem. While there is a growing literature on the association between IPV and women’s reproductive health (RH) outcomes, most studies are cross-sectional—which weakens inference about the causal effect of IPV on women’s RH. This systematic review synthesizes existing evidence from the strongest study designs to estimate the impact of IPV on women’s use of contraception.MethodsWe searched 11 electronic databases from January of 1980 to 3 December 2013 and reviewed reference lists from systematic reviews for studies examining IPV and contraceptive use. To be able to infer causality, we limited our review to studies that had longitudinal measures of either IPV or women’s use of contraception.ResultsOf the 1,574 articles identified by the search, we included 179 articles in the full text review and extracted data from 12 studies that met our inclusion criteria. We limited the meta-analysis to seven studies that could be classified as subject to low or moderate levels of bias. Women’s experience of IPV was associated with a significant reduction in the odds of using contraception (n = 14,866; OR: 0.47; 95% CI: 0.25, 0.85; I² = 92%; 95% CI_I²: 87%, 96%). Restricting to studies that measured the effect of IPV on women’s use of partner dependent contraceptive methods was associated with a reduction in the heterogeneity of the overall estimate. In the three studies that examined women’s likelihood of using male condoms with their partners, experience of IPV was associated with a significant decrease in condom use (OR: 0.48; 95% CI_OR: 0.32, 0.72; I² = 51%; 95% CI_I²: 0%, 86%).ConclusionsIPV is associated with a reduction in women’s use of contraception; women who experience IPV are less likely to report using condoms with their male partners. Family planning and HIV prevention programs should consider women’s experiences of IPV.
