Background: Male partner involvement (MPI) has been recognized as a priority area to be strengthened in Prevention of Mother to Child Transmission (PMTCT) of HIV. We explored the impact of Couple Oriented Counselling (COC) in MPI in sexual and reproductive health and associated factors., Method: From February 2009 to October 2011, pregnant women were enrolled at their first antenatal care visit (ANC-1) and followed up until 6 months after delivery in the Mother and Child Center of the Chantal Biya Foundation within the randomized prenahtest multicentric trial. The MPI index was defined using sexual and reproductive health behaviour variables by using multiple correspondence analysis followed by mixed classification. Men were considered as highly involved if they had shared their HIV test results with their partner, had discussed on HIV or condom used, had contributed financially to ANC, had accompanied their wife to ANC or had practiced safe sex. Factors associated to MPI were investigated by the logistic model with GEE estimation approach., Results: A total of 484 pregnant women were enrolled. The median age of the women was 27 years (IQR: 23-31) and 55.23% had a gestational age greater than 16 weeks at ANC-1. Among them, HIV prevalence was 11.9% (95% CI: 9.0-15.4). The median duration of the women's relationship with their partner was 84 months (IQR: 48-120). MPI index at 6 months after delivery was significantly greater in the COC group than the classical counselling group (14.8% vs 8,82%; p = 0,043; Fig 1). The partners of the women who participated in the COC were more likely to be involved during follow up than others (aOR = 1.45; 95% CI = 1.00-2.10). Partners with no incoming activity (aOR = 2.90; 95% CI = 1.96-4.29), who did not used violence within the couple (aOR = 1.70; 95% CI = 1.07-2.68), and whose partner came early for ANC-1 (aOR = 1.37; 95% CI = 1.00-1.89) were more likely to be involved than others., Conclusion: MPI remains low in stable couples and COC improves partner involvement. Our findings also support the need of strengthening outreach towards "stable" couples and addressing barriers. This could go a long way to improve PMTCT outcomes in Cameroon., Trial Registration: PRENAHTEST, NCT01494961.

Background: Prevention of mother-to-child transmission elimination goals are hampered by low rates of retention in care. The Eliminating Paediatric AIDS in Zimbabwe project assessed whether mother support groups (MSGs) improve rates of retention in care of HIV-exposed infants and their HIV-positive mothers, and maternal and infant outcomes., Methods: The study involved 27 rural clinics in eastern Zimbabwe. MSGs were established in 14 randomly selected clinics and met every 2 weeks coordinated by volunteer HIV-positive mothers. MSG coordinators provided health education and reminded mothers of MSG meetings by cell phone. Infant retention in care was defined as "12 months postpartum point attendance" at health care visits of HIV-exposed infants at 12 months of age. We also measured regularity of attendance and other program indicators of HIV-positive mothers and their HIV-exposed infants., Results: Among 507 HIV-positive pregnant women assessed as eligible, 348 were enrolled and analyzed (69%) with mothers who had disclosed their HIV status being overrepresented. In the intervention arm, 69% of infants were retained in care at 12 months versus 61% in the control arm, with no statistically significant difference. Retention and other program outcomes were systematically higher in the intervention versus control arm, suggesting trends toward positive health outcomes with exposure to MSGs., Discussion: We were unable to show that facility-based MSGs improved retention in care at 12 months among HIV-exposed infants. Selective enrollment of mothers more likely to be retained-in-care may have contributed to lack of effect. Methods to increase the impact of MSGs on retention including targeting of high-risk mothers are discussed.

Background: Consistent use of antiretroviral therapy (ART) during pregnancy and breastfeeding reduces the likelihood of mother-to-child HIV transmission. All pregnant and breastfeeding women living with HIV in Zimbabwe are offered ART with same-day initiation regardless of CD4 count (Option B+). We investigated patterns of clinic attendance and adherence to ART among HIV-infected pregnant women in Zimbabwe., Methods: The Evidence for Elimination cluster-randomized trial evaluating point-of-care CD4 testing included 1150 HIV-infected ART-naive women attending antenatal care between January 2014 and June 2015. Thirty-two primary care facilities were randomized between 2 arms. In this secondary analysis of Evidence for Elimination data collected from routine clinic records, we classified women by number of pills dispensed, and estimated adherence from the ratio of pills to days since ART initiation (Medication Possession Ratio, adherent if ≥95%) or the period when they stopped receiving medication., Results: Two-thirds (67.7%) were still receiving medication 1 year after initiation; less than half of the cohort (39.1%) were adherent. Younger women, newly diagnosed with HIV, and/or first presenting to antenatal care in their third trimester were more likely to drop from care or be nonadherent 360 days after ART initiation., Conclusion: Adherence to ART is suboptimal particularly among young, newly diagnosed, and/or late presenting patients. Interventions that target these groups, as well as provide additional support to all women who are newly diagnosed, may improve Option B+ ART care. More information is needed about the barriers to ART care among late presenters and teenagers.

Background: In Southern Africa, groups of mothers living with HIV successfully provide peer psychosocial support during pregnancy and early childhood. We report patterns of attendance at Mother Support Groups (MSGs) sessions among women and mothers living with HIV in rural Zimbabwe., Methods: In the Elimination of Pediatric AIDS cluster-randomized trial, MSGs were established in 14 health facilities in Mutare and Makoni districts. Patterns of attendance at MSG sessions were categorized by calendar attendance from delivery to 6-month postpartum using a Dynamic Time Warping clustering method. Baseline characteristics of women and postpartum MSG attendance patterns were described. Linkages between these patterns and 12-month postpartum retention in care were explored using mixed-effects models., Results: Most women (88%) attended at least 1 MSG session between enrollment and 6-month postpartum. Two patterns of postpartum MSG attendance, "Regular Attendance" and "Non-Regular Attendance," were readily identified. Being older than 32 (P = 0.01), booking for antenatal care before 22 weeks gestational age (P = 0.02), and being on antiretroviral therapy at first antenatal care booking (P = 0.01) were significantly associated with "Regular Attendance." "Regular Attendance" at MSG sessions during the 6-month postpartum period was significantly associated with better retention in care at 12 months, compared with "Non-Regular Attendance" (P < 0.01)., Discussion: Women living with HIV attended MSG sessions. However, few attended regularly. Younger and newly diagnosed women were less likely to attend postpartum MSG sessions or remain in care at 12 months postpartum. Peer support models should consider specific needs of these women, especially in rural areas, in order for MSGs to contribute to improve maternal and child health outcomes.

The prevent mother-to-child transmission (PMTCT) "cascade" describes the programmatic steps for pregnant and breastfeeding women that influence HIV transmission rates. To this end, HIV-infected pregnant women and mothers need access to health services and adhere to antiretroviral (ARV) prophylaxis or lifetime treatment. Within the cascade, the concept of "retention-in-care" is commonly used as a proxy for adherence to ARV interventions and, even, viral suppression. Yet surprisingly, there is no standard definition of retention-in-care either for the purposes of HIV surveillance or implementation research. Implicit to the concept of retention-in-care is the sense of continuity and receipt of care at relevant time points. In the context of PMTCT, the main challenge for surveillance and implementation research is to estimate effective coverage of ARV interventions over a prolonged period of time. These data are used to inform program management and also to estimate postnatal MTCT rates. Attendance of HIV-infected mothers at clinic at 12-month postpartum is often equated with full retention in PMTCT programs over this period. Yet, measurement approaches that fail to register missed visits, or inconsistent attendance or other missing data in the interval period, fail to capture patterns of attendance and care received by mothers and children and risk introducing systematic errors and bias. More importantly, providing only an aggregated rate of attendance as a proxy for retention-in-care fails to identify specific gaps in health services where interventions to improve retention along the PMTCT cascade are most needed. In this article, we discuss how data on retention-in-care can be understood and analyzed, and what are the implications and opportunities for programs and implementation research.

Objective: Couple-oriented posttest HIV counselling (COC) provides pregnant women with tools and strategies to invite her partner to HIV counselling and testing. We conducted a randomized trial of the efficacy of COC on partner HIV testing in low/medium HIV prevalence settings (Cameroon, Dominican Republic, Georgia, India)., Methods: Pregnant women were randomized to receive standard posttest HIV counselling or COC and followed until 6 months postpartum. Partner HIV testing events were notified by site laboratories, self-reported by women or both combined. Impact of COC on partner HIV testing was measured in intention-to-treat analysis. Socio-behavioural factors associated with partner HIV testing were evaluated using multivariable logistic regression., Results: Among 1943 pregnant women enrolled, partner HIV testing rates (combined indicator) were 24.7% among women from COC group versus 14.3% in standard posttest HIV counselling group in Cameroon [odds ratio (OR) = 2.0 95% CI (1.2-3.1)], 23.1 versus 20.3% in Dominican Republic [OR = 1.2 (0.8-1.8)], 26.8 versus 1.2% in Georgia [OR = 29.6 (9.1-95.6)] and 35.4 versus 26.6% in India [OR = 1.5 (1.0-2.2)]. Women having received COC did not report more conjugal violence or union break-ups than in the standard posttest HIV counselling group. The main factors associated with partner HIV testing were a history of HIV testing among men in Cameroon, Dominican Republic and Georgia and the existence of couple communication around HIV testing in Georgia and India., Conclusion: A simple prenatal intervention taking into account the couple relationship increases the uptake of HIV testing among men in different socio-cultural settings. COC could contribute to the efforts towards eliminating mother-to-child transmission of HIV.

Background: We investigated HIV testing practices at baseline among pregnant women and their partners within a multicountry randomized trial aiming to evaluate the effect of enhanced prenatal posttest HIV counseling on men's involvement., Methods: In Yaoundé, Cameroon, 484 pregnant women with stable partners were recruited on their first antenatal care visit. We analyzed the coverage of previous HIV testing among women and their partners and looked for the factors associated with previous HIV testing, using multivariable logistic regression., Results: Among 476 pregnant women who completed the baseline questionnaire, 408 (85.7%) reported having been tested for HIV already once in their life, 48.3% of them during a previous pregnancy. Women previously tested for HIV were more likely to be in a stable relationship for >5 years than those never tested (P < 0.001). In multivariable analysis, tested women were more likely to be aged between 25 and 30 years compared with women <20 years [odds ratio (OR) 5.5, 95% confidence interval (CI): 1.4 to 22.1], to be able to say whether they felt at risk for HIV infection (OR 2.1, CI: 1.1 to 3.9), and to have ever discussed about HIV with their partner (OR 2.7, CI: 1.1 to 6.4). Most women (85.1%) reported that their partner had already been tested for HIV. Reasons for partner HIV testing were related to self-motivation (30.0%) and clinical symptoms (12.7%)., Conclusions: Strategies aiming at improving knowledge and couple communication about HIV risks need to be considered to address the remaining barriers to HIV testing and contribute to a couple approach to HIV prevention.

Problem: Zimbabwe has one of the highest rates of HIV seroprevalence in the world. In 2001 only 4% of women and children in need of services for prevention of mother to child transmission of HIV were receiving them., Design: Pilot implementation of the first programme for prevention of mother to child transmission of HIV in rural Zimbabwe., Setting: 120 bed district hospital in Buhera district (285,000 inhabitants), Manicaland, Zimbabwe., Key Measures for Improvement: Programme uptake indicators monitored for 18 months; impact of policy evaluated by assessing up-scaling of programme., Strategies for Change: Voluntary counselling and testing services for HIV were provided in the hospital antenatal clinic. Women identified as HIV positive and informed of their serostatus and their newborn were offered a single dose antiretroviral treatment of nevirapine; mother-child pairs were followed up through routine health services. Nursing staff and social workers were trained, and community mobilisation was conducted., Effects of Change: No services for prevention of mother to child transmission of HIV were available at baseline. Within 18 months, 2298 pregnant women had received pretest counselling, and the acceptance of HIV testing reached 93.0%. Of all 2137 women who had an HIV test, 1588 (74.3%) returned to collect their result; 326 of the 437 HIV positive women diagnosed had post-test counselling, and 104 (24%) mother-child pairs received nevirapine prophylaxis., Lessons Learnt: Minimum staffing, an enhanced training programme, and involvement of district health authorities are needed for the implementation and successful integration of services for prevention of mother to child transmission of HIV. Voluntary counselling and testing services are important entry points for HIV prevention and care and for referral to community networks and medical HIV care services. A district approach is critical to extend programmes for prevention of mother to child transmission of HIV in rural settings. The lessons learnt from this pilot programme have contributed to the design of the national expansion strategy for prevention of mother to child transmission of HIV in Zimbabwe.
