A longitudinal study of the relationship between intimate partner violence and postpartum unsafe sex among newly diagnosed HIV-infected South African women

Profiles of Intimate Partner Violence Victimization: A Systematic Review

Person-centered approaches, such as latent class analysis (LCA) and latent profile analysis (LPA), aid the identification of subgroups within sample populations. These methods can identify the patterns of co-occurrence between different forms of intimate partner violence (IPV), providing valuable information for prevention and intervention efforts. The aim of this systematic review was to yield a summary and conduct a critical evaluation of the current research that utilizes LCA/LPA to investigate IPV victimization profiles. We provide an outline of 14 relevant studies, retrieved from searches conducted on PsycInfo, Scopus, and Eric databases. There was a large amount of variability in relation to the forms of IPV assessed, measures utilized, number of classes identified, and the sample populations recruited. However, broad similarities were revealed as there were some commonly identified classes, including the no/low violence class, the physical and psychological victimization class, and the multiple victimization class, yet the labels assigned to those classes differed across studies. A range of external criteria (risk factors and consequences) were also identified as being associated with class membership. We highlight the methodological features which may have impacted data collection and class enumeration, including the differences in sample population, the range of IPV indicators assessed, the time period from which IPV data were recorded, and whether data were collected regarding participants' current or previous relationships. Marginalized populations were underrepresented, and psychological abuse was most inconsistently operationalized. Recommendations for future research are provided, including recommendations with regard to labeling the classes for greater consistency across studies.

A systematic review of the effects of intimate partner violence on HIV-positive pregnant women in sub-Saharan Africa

Background

Intimate partner violence (IPV) affects more than one in three women in sub-Saharan Africa (SSA). It is associated with both pregnancy and HIV, adversely affecting women in this region. This is the first systematic examination of the effects of IPV on HIV-positive (HIV+) pregnant women in SSA.

Methods

A systematic review of the literature on HIV+ pregnant women experiencing IPV in SSA was carried out. Searches were carried out in PubMed, Web of Science and African Journals Online databases. Articles published between January 2010 and June 2020, in English, were included. Data extraction included details on study locations, study design, study participants and the study outcome variables (depression, IPV, medication adherence, postpartum unsafe sex, and HIV disclosure).

Results

Fourteen studies (ten cross-sectional studies, four cohort studies) were included. Results indicate a high prevalence of IPV amongst pregnant women with HIV in SSA (18.0 to 63.1%). The results suggest an association between HIV-positive status and consequences of IPV during pregnancy, particularly mental health effects, such as depression symptoms and suicidal ideation. HIV-related stigma has a key role within the relationship between HIV and IPV during pregnancy. One study described that the presence of IPV reduces adherence to Prevention of Mother-To-Child Transmission (PMTCT) medication. Three studies reported no association between HIV positive status or HIV status disclosure and IPV during pregnancy.

Discussion/conclusions

The systematic review confirms interconnections between IPV and HIV seropositivity amongst pregnant women in SSA. Importantly, stigma, social isolation and poor mental health hinder help-seeking, disclosure, and treatment adherence among HIV+ pregnant women exposed to IPV in SSA. As a result, the potential of community interventions to tackle issues associated with IPV in HIV-positive pregnant women in this area should be explored in research, policy, and practice.

Late antiretroviral refills and condomless sex in a cohort of HIV-seropositive pregnant and postpartum Kenyan women

INTRODUCTION

The postpartum period can be challenging for women living with HIV. Understanding how the postpartum period impacts ART adherence and condomless sex could inform the development of comprehensive sexual and reproductive health and HIV services tailored to the needs of women living with HIV during this critical interval.

METHODS

In a longitudinal cohort study of HIV-seropositive Kenyan women, late ART refills and self-reported condomless sex were compared between the woman's pregnancy and the postpartum period. Analyses were conducted using generalized estimating equations and adjusted for alcohol use, depressive symptoms, intimate partner violence (IPV), and having a recent regular partner. Effect modification was explored for selected variables.

RESULTS AND DISCUSSION

151 women contributed visits. Late ART refills occurred at 7% (32/439) of pregnancy visits compared to 18% (178/1016) during the postpartum period (adjusted relative risk [aRR] 2.44, 95% confidence interval [CI] 1.62-3.67). This association differed by women's education level. Women with ≥8 years of education had late ART refills more during the postpartum period than pregnancy (aRR 3.00, 95%CI 1.95-4.62). In contrast, in women with <8 years of education, late ART refills occurred similarly during pregnancy and the postpartum period (aRR 0.88, 95%CI 0.18-4.35). Women reported condomless sex at 10% (60/600) of pregnancy visits compared to 7% (72/1081) of postpartum visits (aRR 0.76, 95%CI 0.45-1.27). This association differed by whether women had experienced recent IPV. Women without recent IPV had a significant decline in condomless sex from pregnancy to postpartum (aRR 0.53, 95%CI 0.30-0.95) while women with recent IPV had no significant change in condomless sex from pregnancy to postpartum (aRR 1.76, 95%CI 0.87-3.55).

CONCLUSION

Improved support for ART adherence during the postpartum period and addressing IPV to limit condomless sex could improve HIV treatment and prevention outcomes for HIV-seropositive women as well as their infants and sexual partners.

IPV victimization in pregnancy increases postpartum STI incidence among adolescent mothers in Durban, South Africa

Women, and specifically, adolescents, are at high risk of HIV and STIs during the postpartum period. Biological and behavioral factors contribute to adolescents' susceptibility. However, the influence of behavioral factors, like intimate partner violence (IPV), on postpartum STI acquisition has been understudied. The study's purpose is to determine whether IPV victimization during pregnancy predicts incident STIs in the first 6 months postpartum. Adolescent mothers (14-19 years) were recruited at a township hospital's maternity ward near Durban. Adolescent mothers who were HIV-negative and had no laboratory-diagnosed STIs at baseline (6 weeks postpartum) were included in the analysis (n = 61). We used a modified Poisson regression with robust standard errors to assess differences in postpartum STI risk by IPV victimization during pregnancy controlling for covariates. At baseline, 25 (41%) adolescent mothers reported IPV victimization during pregnancy. Adolescent mothers who reported IPV during pregnancy were at higher risk of receiving an STI diagnoses at 6 months postpartum (aRR: 4.43; 95% CI: 1.31-14.97). Our findings heighten understanding of HIV risk among a vulnerable subset of adolescent girls: adolescent mothers. Non-combined interventions that help young mothers and their partners navigate partnership dynamics to reduce IPV and STIs are needed to reduce HIV risk.
