Resumption of sexual activity and regular menses after childbirth among women infected with HIV in Malawi

Early resumption of postpartum sexual intercourse and its associated risk factors among married postpartum women who visited public hospitals of Jimma zone, Southwest Ethiopia: A cross-sectional study

Introduction

Postpartum sexual resumption without the use of contraception is a risk for unintended and closely spaced pregnancies. Although counseling related to the resumption of postpartum sexual intercourse is a key component of postpartum sexual health, it is not widely addressed during the postnatal period. Thus, this study aimed to assess the early resumption of postpartum sexual intercourse and its associated risk factors among married postpartum women who visited public hospitals of Jimma zone, Southwest Ethiopia, for child immunization services.

Methods

The facility-based cross-sectional study design was undertaken, and a systematic random sampling technique was carried out to select 330 participants. Data were collected using a pretested interviewer-administered questionnaire from August to September 2019. Obtained data were analyzed using descriptive statistics. A bivariate analysis was used to determine the significance of the association. Variables that showed association in the bivariate analysis at p-value <0.2 were fitted into a multivariable logistic regression model to control for confounders, and the significance of association was determined at p-value <0.05 with a 95% confidence interval (CI).

Results

Approximately 53.9% of the respondents practiced early resumption of postpartum sexual intercourse. Factors such as low income (AOR = 0.19 (95% CI = 0.10-.37)), monogamous marriage 3.78(1.32–10.79), practicing sexual intercourse during pregnancy (AOR = 4.55 (95% CI = 1.29–15.97)), a cesarean delivery (AOR = 0.06 95%CI = (0.03–0.15)) and use of contraceptives (AOR = 3.7(95%CI = 1.92–7.14)) were significantly associated with early resumption of postpartum sexual intercourse.

Conclusion and recommendation

The findings of this study suggested that, most postpartum mothers resumed sexual intercourse during the early postpartum period and its associated risk factors include low income, monogamous marriage, practicing sexual intercourse during pregnancy, cesarean delivery, and use of contraceptives. Discussion with couples about postpartum sexual health during the antenatal and postnatal period is crucial to prevent unwanted pregnancies and adverse health outcomes.

Timing of HIV testing among pregnant and breastfeeding women and risk of mother-to-child HIV transmission in Malawi: a sampling-based cohort study

INTRODUCTION

Pregnant women living with HIV can achieve viral suppression and prevent HIV mother-to-child transmission (MTCT) with timely HIV testing and early ART initiation and maintenance. Although it is recommended that pregnant women undergo HIV testing early in antenatal care in Malawi, many women test positive during breastfeeding because they did not have their HIV status ascertained during pregnancy, or they tested negative during pregnancy but seroconverted postpartum. We sought to estimate the association between the timing of last positive HIV test (during pregnancy vs. breastfeeding) and outcomes of maternal viral suppression and MTCT in Malawi's PMTCT programme.

METHODS

We conducted a two-stage cohort study among mother-infant pairs in 30 randomly selected high-volume health facilities across five nationally representative districts of Malawi between 1 July 2016 and 30 June 2017. Log-binomial regression was used to estimate prevalence ratios (PR) and risk ratios (RR) for associations between timing of last positive HIV test (i.e. breastfeeding vs. pregnancy) and maternal viral suppression and MTCT, controlling for confounding using inverse probability weighting.

RESULTS

Of 822 mother-infant pairs who had available information on the timing of the last positive HIV test, 102 mothers (12.4%) had their last positive test during breastfeeding. Women who lived one to two hours (PR = 2.15; 95% CI: 1.29 to 3.58) or >2 hours (PR = 2.36; 95% CI: 1.37 to 4.10) travel time to the nearest health facility were more likely to have had their last positive HIV test during breastfeeding compared to women living <1 hour travel time to the nearest health facility. The risk of unsuppressed VL did not differ between women who had their last positive HIV test during breastfeeding versus pregnancy (adjusted RR [aRR] = 0.87; 95% CI: 0.48 to 1.57). MTCT risk was higher among women who had their last positive HIV test during breastfeeding compared to women who had it during pregnancy (aRR = 6.57; 95% CI: 3.37 to 12.81).

CONCLUSIONS

MTCT in Malawi occurred disproportionately among women with a last positive HIV test during breastfeeding. Testing delayed until the postpartum period may lead to higher MTCT. To optimize maternal and child health outcomes, PMTCT programmes should focus on early ART initiation and providing targeted testing, prevention, treatment and support to breastfeeding women.

Resumption of postpartum sexual activity and menses among HIV-infected women on lifelong antiretroviral treatment compared to HIV-uninfected women in Africa

OBJECTIVE

To determine time from delivery to resumption of sexual activity and menses among HIV-infected women on antiretroviral treatment (ART) and HIV-uninfected women.

METHODS

HIV-infected women on ART and HIV-uninfected women were recruited from five health facilities at delivery and followed prospectively for a maximum of 1 year in Blantyre, Malawi from January 2016 to September 2017. Sociodemographic, clinical, and laboratory data were collected at delivery and 1.5, 3, 6, 9, and 12 months. Descriptive, time to event Kaplan-Meier, and multivariable Cox proportional hazards analyses were conducted.

RESULTS

Data on 878 women (460 [52.4%] HIV-uninfected and 418 [47.6%] HIV-infected, P=0.156) who attended at least one follow-up visit were analyzed. Among HIV-uninfected compared to HIV-infected women, respectively, the median number of days to resumption of sexual activity was 180 vs 181; to irregular menses was 82 vs 71; and to regular menses was 245 vs 366. In multivariable models, being married was associated with early resumption of sexual activity (hazard ratio [HR] 1.91, P<0.001), and being HIV-infected and use of an effective method of family planning were associated with later start of regular menses (HR<1.0, P<0.050).

CONCLUSION

Counseling of women on reproductive intentions should start early irrespective of HIV infection or use of ART.

The Role of Culture in Maintaining Post-Partum Sexual Abstinence of Swazi Women

Eswatini is one of the countries in the African continent where post-partum sexual abstinence is practiced. Beside scarcity of research exploring sexual abstinence in Eswatini, there are only a few studies that explore post-partum abstinence across HIV-positive and negative women in sub-Saharan Africa. The study explored the practice of post-partum sexual abstinence in Swazi women and examined how cultural beliefs influence and promotes the perpetuation of the practice. The study population consisted of post-partum women who were selected, using purposive sampling. Thematic approach was used for data analysis. Despite feeling that the period for post-partum, sexual abstinence was long; the participants adhered to the practice as prescribed by their culture. Nevertheless, they felt that the practice is imposed on women only because while they are observing post-partum abstinence, their partners get to sleep with other sexual partners. They raised concerns that the practice increases the risk of acquiring HIV and sexually transmitted infections. There is an element of coercion to the practice of post-partum abstinence, the myths and misconceptions around the early resumption of sexual intercourse forces the practice on women. At the family and community level, the discussions to change the way sexual abstinence is viewed and practiced are crucial.

Sexual Behavior and Vaginal Practices During Pregnancy and Postpartum: Implications for HIV Prevention Strategies

BACKGROUND

Understanding sexual behaviors and vaginal practices of pregnant and breastfeeding women in sub-Saharan Africa is critical to inform HIV prevention strategies during these periods.

METHODS

HIV-uninfected women presenting for antenatal care in western Kenya were enrolled and followed through 36 weeks postpartum. Sexual behavior and vaginal practices were ascertained by structured questionnaires. Logistic regression was used to assess correlates of unprotected sex, vaginal washing, and vaginal drying.

RESULTS

Among 1252 women enrolled, 78.4% were married (of whom 15.1% were in polygamous unions), 1.4% had a known HIV-infected partner, and 33.6% had a partner of unknown HIV status. At enrollment, 58.5% reported sex in the past month (94.3% unprotected) and 4.5% reported forced sex. Odds of unprotected sex at enrollment was >11-fold higher in married than in unmarried women (P < 0.001) and lower among women who reported partners of unknown HIV status or HIV-infected compared with HIV-uninfected partners. Median time to postpartum resumption of sex was 7 weeks (interquartile range 4-12). Prevalence of unprotected sex in the past week increased from 6.6% to 60.0% between 2 and 36 weeks postpartum (P < 0.001). Vaginal washing was reported by 60.1% of women at enrollment and prevalence remained stable postpartum; vaginal drying was reported by 17.9% at enrollment and decreased to 6.1% at 36 weeks postpartum (P < 0.001). Vaginal washing and drying were associated with forced sex.

CONCLUSIONS

High rates of unknown partner HIV status, polygamy, and less frequent condom use among pregnant/postpartum women underscore the need for female-controlled HIV prevention interventions. Vaginal washing and drying may present challenges to microbicide use.

Factors associated with early resumption of sexual intercourse among postnatal women in Uganda

Background

Despite being a key component to be addressed during postnatal period, sexuality has long been a subject of secrecy and taboo in Africa. Resumption of sexual intercourse after giving birth has been shown to reduce extramarital affairs and consequently reduce risk of sexually transmitted infections like HIV/AIDS. Consequences of early resumption of sexual intercourse include unwanted pregnancy, genital trauma and puerperal infection. The objective of the study was to assess prevalence and factors associated with early resumption of sexual intercourse among postnatal mothers attending postnatal clinic at a National referral Hospital in Uganda.

Methodology

A cross-sectional study that employed an interviewer-administered questionnaire was conducted among 374 women who delivered six months prior to conducting the study. The independent variables included socio-demographic characteristics of the participant, socio-demographic characteristics of the spouse, perceived cultural norms, medical history, mode of delivery, and postpartum complications. The dependent variable was timing of resumption of sexual intercourse after childbirth (before or after six weeks postpartum). Data were analysed using SPSS version 16.0.

Results

The study showed that 105 participants (21.6 %) had resumed sexual intercourse before 6 weeks after childbirth. The participants’ education level, occupation, and parity; education level of the spouse, age of baby and use of family planning were the factors associated with early resumption of sexual intercourse after child birth (before six weeks postpartum) (p < 0.05).

Conclusion

Many women resumed sexual intercourse after six weeks. Women with high income, low parity, who ever-used contraception or had a spouse with high education level were more likely to have early resumption of sexual intercourse.

Evaluation of postpartum HIV superinfection and mother-to-child transmission

OBJECTIVE

This study examined HIV superinfection in HIV-infected women postpartum, and its association with mother-to-child transmission (MTCT).

DESIGN

Plasma samples were obtained from HIV-infected women who transmitted HIV to their infants after 6 weeks of age (transmitters, n = 91) and HIV-infected women who did not transmit HIV to their infants (nontransmitters, n = 91). These women were originally enrolled in a randomized trial for prevention of MTCT of HIV in Malawi (Post-Exposure Prophylaxis of Infants trial in Malawi).

METHODS

Two HIV genomic regions (p24 and gp41) were analyzed by next-generation sequencing for HIV superinfection. HIV superinfection was established if the follow-up sample contained a new, phylogenetically distinct viral population. HIV superinfection and transmission risk were examined by multiple logistic regression, adjusted for Post-Exposure Prophylaxis of Infants study arm, baseline viral load, baseline CD4 cell count, time to resumption of sex, and breastfeeding duration.

RESULTS

Transmitters had lower baseline CD4 cell counts (P = 0.001) and higher viral loads (P < 0.0001) compared with nontransmitters. There were five cases of superinfection among transmitters (rate of superinfection = 4.7/100 person-years) compared with five cases among the nontransmitters (rate of superinfection = 4.4/100 person-years; P = 0.78). HIV superinfection was not associated with increased risk of postnatal MTCT of HIV after controlling for maternal age, baseline viral load, and CD4 cell count (adjusted odds ratio = 2.32, P = 0.30). Longer breastfeeding duration was independently associated with a lower risk of HIV superinfection after controlling for study arm and baseline viral load (P = 0.05).

CONCLUSION

There was a significant level of HIV superinfection in women postpartum, but this was not associated with an increased risk of MTCT via breastfeeding.

[Consensus statement on monitoring of HIV: pregnancy, birth, and prevention of mother-to-child transmission]

OBJECTIVE

The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit.

METHODS

We assembled a panel of experts appointed by the Secretariat of the National AIDS Plan (SPNS) and the other participating Scientific Societies, which included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists. Four panel members acted as coordinators. Scientific information was reviewed in publications and conference reports up to November 2012. In keeping with the criteria of the Infectious Diseases Society of America, 2levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C), and the level of empirical evidence (I, II, III). This approach has already been used in previous documents from SPNS.

RESULTS AND CONCLUSIONS

The aim of this paper was to review current scientific knowledge, and, accordingly, develop a set of recommendations regarding antiretroviral therapy (ART), regarding the health of the mother, and from the perspective of minimizing mother-to-child transmission (MTCT), also taking into account the rest of the health care of pregnant women with HIV infection. We also discuss and evaluate other strategies to reduce the MTCT (elective Cesarean, child's treatment…), and different aspects of the topic (ARV regimens, their toxicity, monitoring during pregnancy and postpartum, etc.).

Resumption of vaginal intercourse in the early postpartum period: determinants and considerations for child spacing in a Nigerian population

A total of 860 mothers were interviewed during their first postnatal clinic visit to determine the factors that influenced their resumption of sexual intercourse as well as their family planning practices in the early postpartum period. Some 255 (29.7%) women had resumed sexual intercourse with a mean delivery - resumption interval of 5.4 ± 2.6 weeks. Resumption of menses and HIV-negative status were the factors most significantly associated with resumption of sexual intercourse. Other significant determinants were urban residence and vaginal delivery without tears. Only 21.5% of the sexually active mothers used a modern contraceptive in the form of a male condom, while 56.9% did not consider contraception at all. The major reason for prolonged abstinence was fear of another pregnancy. In this group of women, child spacing appears to be the major consideration for resumption of coitus, even over the fear of painful discomfort.

High HIV incidence and sexual behavior change among pregnant women in Lilongwe, Malawi: implications for the risk of HIV acquisition

Background

HIV incidence is higher among pregnant women than their non-pregnant counterparts in some sub-Saharan African settings. Our aims were (1) to estimate HIV incidence during pregnancy and (2) to compare sexual activity between pregnant, postpartum, and non-pregnant women.

Methods

We examined a retrospective cohort of 1087 women to identify seroconverters using antenatal and labor ward HIV test results. We also conducted a cross-sectional survey, including a quantitative questionnaire (n = 200) and in-depth interviews (n = 20) among women in early pregnancy, late pregnancy, postpartum, and non-pregnancy. Outcomes included measures of sexual activity, reported spouse’s risky behavior, and beliefs about abstinence.

Results

11 of 1087 women seroconverted during pregnancy yielding a 1% seroconversion risk and an incidence rate of 4.0/100 person years (95% CI 2.2–7.2). The reported sexual activity of the early pregnancy and non-pregnancy groups was similar, but significantly higher than the late pregnancy and postpartum groups (p<0.001). During pregnancy, sex acts decreased as gestation increased (p = 0.001). There was no reported difference in the spouse’s risky behavior. Most women believed that sex should cease between the 6^th and 8^th month of pregnancy and should not resume until 6 months postpartum. Some talked about conflict between their cultural obligation to abstain and fear of HIV infection if their spouses find other partners.

Conclusions

HIV incidence is high among pregnant women in Malawi, and sexual activity decreases during pregnancy and postpartum. Pregnant women need to be informed of their increased risk for HIV and the importance of using condoms throughout pregnancy and the postpartum period.
