Do Couple-Based Interventions Show Larger Effects in Promoting HIV Preventive Behaviors than Individualized Interventions in Couples? A Systematic Review and Meta-analysis of 11 Randomized Controlled Trials

This systematic review and meta-analysis aims to compare the effects of couple-based prevention interventions against individual-level interventions on HIV prevention in randomized controlled trials (RCTs), identify potential moderators, and assess study quality. Eleven RCTs were included, comprising 3933 couples in the intervention group and 7125 individuals in the individual control group, predominantly in heterosexual couples from the USA and Africa. Couple-based interventions had a more significant effect in promoting condom use and HIV testing. Education levels of high school or above, residence in low- and middle-income countries, and intervention design incorporating HIV counseling and testing were associated with higher odds of condom use. The quality assessment analysis identified methodological and theoretical heterogeneity factors. Evidence of couple-based HIV prevention RCTs among men who have sex with men, injecting drug users, sex workers, and transgender women warrant further investigation. Recommendations are made to improve the quality and replicability of future intervention studies.

HIV serostatus disclosure to sexual partner: a survey among women in Tehran, Iran

BACKGROUND

Disclosure of HIV-positive status in women is associated with many factors. Consequently, status disclosure remains a challenge for Iranian women living with HIV. This study aimed to assess the prevalence, related factors, and reflections of HIV-positive status disclosure to a sexual partner(s) among Iranian women living with HIV.

METHODS

A cross-sectional study was conducted on 170 HIV-seropositive women. Participants were selected from patients registered in the largest HIV clinic and HIV-positive club of Iran. The "HIV disclosure" questionnaire had 38-items and all the interviews were administered by the researcher. Data were analyzed using SPSS version 21.0 software. We used a logistic regression method to calculate the crude odds ratio (COR) and the adjusted odds ratio (AOR) for self-disclosure as the independent predictor variable and the dependent variable, respectively.

RESULTS

One hundred and seventy HIV-positive women were enrolled. Most of them had disclosed their HIV status to at least one person (94.1%) and their sexual partners (86.5%). In the univariate analysis, being married (COR = 18.66, 95% CI 5.63-61.87), living with a sexual partner (COR = 4.72, 95% CI 1.92-11.62), being aware of sexual partners' HIV status (COR = 6.20, 95% CI 1.79-21.49), and gaining the support of sexual partner (COR = 9.08, 95% CI 3.48-23.64) were associated with higher odds of HIV status disclosure. In the multivariate analysis, being aware of sexual partners' HIV status, and gaining the support of sexual partners remained associated with HIV status disclosure. Most women reported a positive reflection from their sexual partners after disclosure, however, negative reflections from society were more common compared to sexual partners and family members.

CONCLUSION

This study shows high overall HIV disclosure proportions. It should be noted that a large number of women were infected by their sexual partners, especially by their spouses. The high rate of transmission in married people indicates an urgent need for more emphasis on appropriate prevention behaviors by infected partners.

"It really proves to us that we are still valuable": Qualitative research to inform a safer conception intervention for men living with HIV in South Africa

Objective

Many men living with HIV want to have children. Opportunities to reduce periconception HIV transmission include antiretroviral therapy as prevention, pre-exposure prophylaxis, limiting condomless sex to peak fertility, and sperm processing. Whether men have knowledge of or want to adopt these strategies remains unknown.

Methods

We conducted focus group discussions (FGDs) with men accessing HIV care in South Africa in 2014 to inform a safer conception intervention for men. Eligible men were 25–45 years old, living with HIV, not yet accessing treatment, and wanting to have a child with an HIV-negative or unknown serostatus female partner (referred to as the “desired pregnancy partner”). FGDs explored motivations for having a healthy baby, feasibility of a clinic-based safer conception intervention, and acceptability of safer conception strategies. Data were analyzed using thematic analysis.

Results

Twelve participants from three FGDs had a median age of 37 (range 23–45) years, reported a median of 2 (range 1–4) sexual partners, and 1 (range 1–3) desired pregnancy partner(s). A third (N = 4) had disclosed HIV-serostatus to the pregnancy partner. Emergent themes included opportunities for and challenges to engaging men in safer conception services. Opportunities included enthusiasm for a clinic-based safer conception intervention and acceptance of some safer conception strategies. Challenges included poor understanding of safer conception strategies, unfamiliarity with risk reduction [versus “safe” (condoms) and “unsafe” (condomless) sex], mixed acceptability of safer conception strategies, and concerns about disclosing HIV-serostatus to a partner.

Conclusions

Men living with HIV expressed interest in safer conception and willingness to attend clinic programs. Imprecise prevention counseling messages make it difficult for men to conceptualize risk reduction. Effective safer conception programs should embrace clear language, e.g. undetectable = untransmittable (U = U), and support multiple approaches to serostatus disclosure to pregnancy partners.

Are Male Partners the Missing Link to Eliminating Mother-To-Child Transmission of HIV in Sub-Saharan Africa? Evidence From a Retrospective Case-Control Study

When male partners of pregnant women living with HIV do not participate in antenatal care, it decreases the uptake of prevention of mother-to-child transmission interventions, which increases the risk of HIV transmission to newborns. We evaluated the association of male partner involvement and vertical HIV transmission at 6 weeks along 4 constructs: antenatal clinic accompaniment, mother's awareness of partner HIV status, disclosure of mother's HIV status to partner, and couple testing. Thirty-three HIV-exposed infants with positive 6-week polymerase chain reaction (PCR) results were compared with 144 HIV-exposed infants with a negative PCR. Mothers of PCR-negative infants were 14 times more likely to have disclosed their HIV status to their partners (odds ratio [OR] = 14.1 [5.0-39.4]), to be aware of partner HIV status (OR = 0.2 [0.1-0.96]), and to have been accompanied by their male partners to the antenatal clinic (OR = 0.6 [0.5-0.9]). There is a need for male engagement in prevention of mother-to-child transmission programs.

Improving male involvement in antenatal care in low and middle-income countries to prevent mother to child transmission of HIV: A realist review

BACKGROUND

Childhood Human Immunodeficiency Virus (HIV) infection occurs almost exclusively via mother to child transmission (MTCT) during pregnancy, birth, or through breastfeeding. Recent studies have shown that male involvement (MI) in antenatal care (ANC) and HIV testing, including couples voluntary counselling and testing (CVCT), increases the likelihood that women will adhere to prevention advice and comply with HIV treatment if required during their pregnancy; hence reducing the rates of MTCT of HIV. This realist review investigates how, why, when, and for whom MI in ANC works best to provide contextual advice on how MI in ANC can be best used for prevention of mother to child transmission (PMTCT) of HIV.

METHODS

A realist review of existing evidence was conducted. Realist review seeks to explain how and why an intervention works, or does not work, in a given context. This was completed through the five stages of realist synthesis; Eliciting the program theory, search strategy, study selection criteria, data extraction, and data analysis and synthesis. Findings are presented as context-mechanism-outcome (CMO) configurations outlining the mechanisms that work in given contexts to give an outcome.

RESULTS

Three CMO configurations were developed. These describe that 1) Couples in monogamous relationships have higher levels of trust, commitment and security leading to increased uptake of PMTCT programs together; 2) ANC spaces that make 'male friendly' adaptions promote normalisation of MI in PMTCT and are more welcoming, leading to increased willingness of male partners to participate in ANC; and 3) couples and communities with higher health literacy encourage increased informed decision making, ownership, and responsibility and thus increased participation in PMTCT of HIV.

CONCLUSIONS

The CMOs developed in this review give contextual advice on how one might improve ANC services to increase MI and help reduce MTCT of HIV. We propose that MI in ANC works best where couples are monogamous and trusting, where ANC spaces actively promote being a 'male friendly space' and where there are high levels of community education programs around MTCT.

Factors influencing sexually transmissible infection disclosure to male partners by HIV-positive pregnant women in Pretoria townships, South Africa: a qualitative study

Background Sexually transmissible infections (STI) may increase the risk of mother-to-child transmission (MTCT) of HIV. However, diagnostic testing and targeted treatment of STI (STI-TT) during pregnancy is not standard care in South Africa.

METHODS

A qualitative study was nested in a STI-TT intervention to investigate motivating and enabling factors associated with STI test results disclosure to sexual partners. A semi-structured interview protocol covered partner communication, HIV and STI disclosure, financial security and relationships dynamics. Interviews were conducted in participants' preferred language, audio-recorded, transcribed into English and analysed using a constant comparison approach. The study was conducted in two townships in Pretoria, South Africa.

RESULTS

Twenty-eight HIV-positive pregnant women were interviewed. Based on the interviews, two disclosure experiences for women were identified - those with vulnerable experiences and those with self-enabling experiences within their partnerships. Vulnerable women discussed intimate partner violence (IPV) and fear of relationship dissolution as factors influencing their test result disclosure. Self-enabled women discussed their ability to talk with their partners about STI and HIV infections and the influence of multiple concurrent partnerships in the acquisition of HIV/STIs. Both groups of women were concerned about men's health behaviours, and all cited the health and development of their unborn child as a key motivator for test result disclosure.

CONCLUSIONS

Improved counselling and support for pregnant women to disclose their STI test results to their partners may improve the impact of STI diagnostic testing during pregnancy by improving partner treatment uptake and thus reducing the risk of re-infection.

Correlates of HIV-Positive Fathers' Involvement in Prevention of Mother-to-child Transmission Programs in Northern Nigeria

BACKGROUND

The involvement of men in prevention of mother-to-child HIV transmission (PMTCT) programs could accelerate the elimination of vertical transmission. Yet, little research has focused on HIV-positive male partners. This study determined the predictors of male partners' PMTCT knowledge and involvement in a tertiary hospital in northern Nigeria.

METHODS

A clinic-based sample of 401 HIV-positive male partners of women who delivered within 12 months prior were interviewed using structured questionnaires. PMTCT knowledge and involvement scores were computed. Adjusted odd ratios (AOR) for predictors were derived from multivariate logistic regression models.

RESULTS

The proportion of respondents with adequate PMTCT knowledge was 40.9%. Less than half (43.6%) of the respondents participated in PMTCT, with median involvement score of 2.00 (interquartile range, IQR = 0, 5.0). One quarter of respondents (25.7%, n =103) reported >1 sex partners, 10.5% consistently used condoms, and 20.7% had disclosed to all partners. Fathers' involvement in PMTCT was predicted by paternal education (AOR = 0.30; 95% Confidence Interval (CI): 0.12-0.77, no formal vs. post-secondary), HIV-positive child (AOR = 3.85; 95%CI: 1.41-10.54, yes vs. no), treatment duration (AOR = 4.17; 95%CI: 1.67-10.41, ≤1 vs. ≥10 years), disclosure to partner(s) (AOR = 1.21; 95%CI: 1.15-3.52, 'disclosed to all' vs. 'not disclosed'), condom use (AOR = 5.81; 95%CI: 3.07-11.0, always vs. never), and PMTCT knowledge (AOR = 0.62; 95%CI: 0.31-0.92, inadequate versus adequate).

CONCLUSION

The involvement of fathers in HIV PMTCT programs was low and predicted by paternal education, HIV-positive child, duration of antiretroviral treatment, disclosure to partner, consistent condom use, and level of PMTCT knowledge. Our findings will inform the development of policies to increase male partner involvement in PMTCT in Nigeria.

Pathways for HIV Prevention Behaviors Following a Home-Based Couples Intervention for Pregnant Women and Male Partners in Kenya

Pregnancy is a time of heightened HIV risk, but also a phase when a couple can prioritize family health. We conducted secondary analysis of a home-based intervention in rural Kenya to explore couple-level adherence to HIV prevention behaviors. The intervention included health education, relationship-building skills, and Couples HIV Testing and Counseling. Pregnant women were randomized to the intervention (n = 64) or standard care (n = 63) along with male partners. Of 96 couples, 82 (85.0%) were followed to 3 months postpartum, when 31.0% of couples reported perfect adherence to HIV prevention. In logistic regression, intervention condition couples had three-fold higher odds of perfect adherence (AOR = 3.07, 95% CI = 1.01-9.32). A structural equation model found the intervention had moderate effects on couple communication, large effects on couple efficacy to take action around HIV, which in turn improved HIV prevention behaviors (CFI = 0.969; TLI = 0.955; RMSEA = 0.049). Strengthening couple communication and efficacy may help prevent the spread of HIV to infants or partners around the time of pregnancy.

'PrEP should be for men only': Young heterosexual men's views on PrEP in rural South Africa

BACKGROUND

Gaps persist in HIV testing, treatment, and prevention services for men, leading to higher attributable mortality compared to women. We sought to characterise HIV prevention knowledge, risk behaviours, and interest in pre-exposure prophylaxis (PrEP) among young men in rural South Africa.

METHODS

We conducted interviews with HIV-negative heterosexual men which were thematically analysed to identify key themes.

RESULTS

Among 31 participants, median age was 26 (IQR23-31), 77% were unemployed, 52% reported previous STI, 84% reported casual sexual partners. Men acknowledged inconsistent condom use with multiple partners, reporting high-risk sexual behaviour despite recognised risk. Mistrust between partners was common. Respondents reported willingness to take PrEP to protect themselves and their partner, though anticipated stigma and structural barriers. Men worried that if their female partner had PrEP, she would become sexually active with others.

CONCLUSIONS

In rural South Africa, young heterosexual men acknowledged high HIV-risk behaviour, expressed concern about acquiring HIV, and recognised the value of PrEP. Men were often not supportive of their female partners taking PrEP. Implementing HIV prevention services needs to incorporate young men's perspectives and may require gender-specific interventions, including addressing stigma, differentiated service delivery models such as community-based services or adapting facility services to target men.

The role of male partner in utilization of maternal health care services in Ethiopia: a community-based couple study

BACKGROUND

Ethiopia has recorded substantial progress in maternal health recently. However, poor utilization of maternal health care services is challenging further improvement. Although male partners are decision-makers in households, the impact of their involvement on maternal health care services has not been well studied. Thus, the objective of this study was to examine the association between male partners' involvement in maternal health care on utilization of maternal health care services.

METHODS

A community-based cross-sectional study was conducted on male/female couples with a baby less than 6 months old (N = 210) in Addis Ababa, Ethiopia. The main independent variable of the study was male partners' involvement in maternal health care. Two structured questionnaires were used to collect the data from men and women. Bivariate and multivariate logistic regression models were used to examine the relationship between the dependent and independent variables.

RESULTS

Mean age in years was 28.7 (SD = 5.4) for women and 36.2 (SD = 8.8) for men. Half of the men (51.4%) have accompanied their partner to antenatal care (ANC) at least once. However, only 23.1% of them have physically entered the ANC room together. Overall involvement of male partners was poor in 34.8% of the couples (involved in two or fewer activities). After controlling for other covariates, the odds of having 1st ANC visit within the first trimester of pregnancy and skilled delivery attendant at birth were higher in women whose male partners took time to know what happened during ANC visits (AOR = 1.93; 95%CI = 1.04-3.60; AOR = 2.93; 95%CI = 1.24-5.6.90, respectively). Similarly, the odds of having at least one ANC visit, first ANC visit within twelve weeks, HIV testing, skilled birth attendant, and birth in a health facility were higher in couples with higher overall male partner involvement.

CONCLUSION

The study demonstrated significant associations between male partners' involvement in maternal health care and utilization of some maternal health care services by female partners.

Sexual risk behaviour among HIV-infected women in the first twelve months after delivery in South Africa

This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on their sexual activity six to twelve months after delivery; including use of condoms and partner involvement. Generalised linear mixed models were utilised to estimate unsafe sex outcomes from a prevention of mother to child transmission (PMTCT) intervention, socio-demographic factors, disclosure, and male involvement. About 20% of sexually active women in the past week had used condoms inconsistently at six and twelve months after delivery. Moreover, 16% and 18% of the women had not used a condom at last sex and 11% and 13% had unprotected sex with HIV-uninfected or unknown-status partners following delivery at six and twelve months, respectively. Higher inconsistent condom use was likely with lower male involvement. Promotion of condom use post-partum, as well as male involvement in sexual decisions, are important for safer sex post-partum by seropositive women.

Measuring couple relationship quality in a rural African population: Validation of a Couple Functionality Assessment Tool in Malawi

Available data suggest that individual and family well-being are linked to the quality of women’s and men’s couple relationships, but few tools exist to assess couple relationship functioning in low- and middle-income countries. In response to this gap, Catholic Relief Services has developed a Couple Functionality Assessment Tool (CFAT) to capture valid and reliable data on various domains of relationship quality. This tool is designed to be used by interventions which aim to improve couple and family well-being as a means of measuring the effectiveness of these interventions, particularly related to couple relationship quality. We carried out a validation study of the CFAT among 401 married and cohabiting adults (203 women and 198 men) in rural Chikhwawa District, Malawi. Using psychometric scales, the CFAT addressed six domains of couple relationship quality (intimacy, partner support, sexual satisfaction, gender roles, decision-making, and communication and conflict management), and included questions on intimate partner violence. We used exploratory factor analysis to assess scale performance of each domain and produce a shortened Relationship Quality Index (RQI) composed of items from five relationship quality domains. This article reports the performance of the RQI. Internal reliability and validity of the RQI were found to be good. Regression analyses examined the relationship of the RQI to outcomes important to health and development: intra-household cooperation, positive health behaviors, intimate partner violence, and gender-equitable norms. We found many significant correlations between RQI scores and these couple- and family-level development issues. There is a need to further validate the tool with use in other populations as well as to continue to explore whether the observed linkages between couple functionality and development outcomes are causal relationships.

HIV status disclosure, facility-based delivery and postpartum retention of mothers in a prevention clinical trial in rural Nigeria

Background

Within the context of a cluster randomized prevention of mother-to-child HIV transmission (PMTCT) trial, we evaluated the impact of disclosure on selected PMTCT continuum of care measures.

Methods

In 12 rural matched-pair clinics randomly assigned to an intervention package versus standard-of-care, we enrolled 372 HIV-infected pregnant women from April 2013 to March 2014. This secondary analysis included 327 (87.9%) women with unknown HIV status or who were treatment naïve at presentation to antenatal care. We employed mixed effects logistic regression to estimate impact of disclosure on facility delivery and postpartum retention in HIV care at 6 and 12 weeks.

Results

Fully 86.5% (283/327) of women disclosed their HIV status to their partner, more in the trial intervention arm (OR 3.17, 95% CI 1.39-7.23). Adjusting for intervention arm, maternal age, education and employment, women who disclosed were more likely to deliver at a health facility (OR 2.73, 95%CI 1.11-6.72). Participants who disclosed also had a trend towards being retained in care at 6 and 12 weeks' postpartum (OR 2.72, 95% CI 0.79-9.41 and 2.46, 95% CI 0.70-8.63, respectively).

Conclusions

HIV status disclosure at 6 weeks' postpartum was positively associated with facility-based delivery, but not with early postpartum retention. Facilitating HIV status disclosure to partners can increase utilization of facility obstetric services.

Taking into Account the Quality of the Relationship in HIV Disclosure

Despite growing interest in HIV disclosure, most theoretical frameworks and empirical studies focus on individual and social factors affecting the process, leaving the contribution of interpersonal factors relatively unexplored. HIV transmission and disclosure often occur within a couple however, and this is where disclosure has the most scope as a HIV transmission intervention. With this in mind, this study explores whether perceived relationship quality influences HIV disclosure outcomes. Ninety-five UK individuals with HIV participated in a cross-sectional survey. Retrospective data were collected on their perceived relationship quality prior to disclosing their HIV positive status, and on disclosure outcomes. Perceived relationship quality was found to significantly affect disclosure outcomes. Positive qualities in the relationship were associated with positive outcomes, whereas negative qualities were associated with negative outcomes. Results further confirmed that this association was not merely correlational, but demonstrated predictive power. Relationship quality might act as either a risk or a resilience factor in the disclosure process, and thus warrants greater attention in future research.

Male partners' involvement in prevention of mother-to-child HIV transmission in sub-Saharan Africa: A systematic review

In sub-Saharan Africa (SSA), male partners are rarely present during prevention of mother-to-child transmission (PMTCT) services. This systematic review aims to synthesize, from a male perspective, male partners' perceived roles, barriers and enablers of their involvement in PMTCT, and highlights persisting gaps. We carried out a systematic search of papers published between 2002 and 2013 in English on Google Scholar and PubMed using the following terms: men, male partners, husbands, couples, involvement, participation, Antenatal Care (ANC), PMTCT, SSA countries, HIV Voluntary Counseling and Testing and disclosure. A total of 28 qualitative and quantitative original studies from 10 SSA countries were included. Men's perceived role was addressed in 28% (8/28) of the studies. Their role to provide money for ANC/PMTCT fees was stated in 62.5% (5/8) of the studies. For other men, the financial responsibilities seemed to be used as an excuse for not participating. Barriers were cited in 85.7% (24/28) of the studies and included socioeconomic factors, gender role, cultural beliefs, male unfriendly ANC/PMTCT services and providers' abusive attitudes toward men. About 64% (18/28) of the studies reported enablers such as: older age, higher education, being employed, trustful monogamous marriages and providers' politeness. In conclusion, comprehensive PMTCT policies that are socially and culturally sensitive to both women and men need to be developed.

Community Cultural Norms, Stigma and Disclosure to Sexual Partners among Women Living with HIV in Thailand, Brazil and Zambia (HPTN 063)

BACKGROUND

Serostatus disclosure may facilitate decreased HIV transmission between serodiscordant partners by raising risk awareness and heightening the need for prevention. For women living with HIV (WLWH), the decision to disclose may be influenced by culturally determined, community-level stigma and norms. Understanding the impact of community HIV stigma and gender norms on disclosure among WLWH in different countries may inform intervention development.

METHODS

HPTN063 was a longitudinal, observational study of sexually active HIV-infected individuals, including heterosexual women, in care in Zambia, Thailand and Brazil. At baseline, a questionnaire measuring community HIV stigma and gender norms, anticipated stigma, demographic, partner/relationship characteristics, and intimate partner violence was administered. Longitudinal HIV disclosure to sexual partners was determined via audio-computer assisted self-interview (ACASI) at the baseline and quarterly during the one year following up. Logistic regression was conducted to identify the predictors of disclosure.

RESULTS

Almost half (45%) of women living with HIV acknowledged perceived community HIV stigma (the belief that in their community HIV infection among women is associated with sex work and multiple sexual partners). Many women (42.9%) also acknowledged perceived community gender norms (the belief that traditional gender norms such as submissiveness to husbands/male sexual partners is necessary and that social status is lost if one does not procreate). HIV disclosure to current sex partners was reported by 67% of women. In multivariate analysis, among all women, those who were older [OR 0.16, 95%CI(0.06,0.48)], reported symptoms of severe depression [OR 0.53, 95%CI(0.31, 0.90)], endorsed anticipated stigma [OR 0.30, 95%CI(0.18, 0.50)], and were unmarried [OR 0.43, 95%CI(0.26,0.71)] were less likely to disclose to current partners. In an analysis stratified by marital status and cohabitation, unmarried [OR 0.41, 95%CI(0.20,0.82)] and non-cohabiting women [OR 0.31, 95%CI(0.13,0.73)] who perceived community HIV stigma were less likely to disclose to their sex partners.

CONCLUSIONS

Perceived community level HIV stigma, along with individual level factors such as anticipated stigma, depressive symptoms, and older age, predict non-disclosure of HIV status to sexual partners among WLWH in diverse geographic settings. Interventions to promote disclosure among women in serodiscordant relationships should incorporate community-level interventions to reduce stigma and promote gender equality.

The 'Fears' of Disclosing HIV Status to Sexual Partners: A Mixed Methods Study in a Counseling Setting in Ghana

Encouraging disclosure within a trusting and supportive environment is imperative in dealing with HIV/AIDS related stigma. However, disclosure rates and the factors that influence it are vaguely understood in African societies. This study aimed at determining the disclosure rate and factors that influence disclosure in Cape Coast, Ghana. In-depth interviews of 15 peer educators and a survey of 510 PLHIV were used in a mixed methods study design. Majority of the study participants (78.6 %) had disclosed their HIV positive status to their sexual partners. Although peer educators in this study portrayed the overall outcome of disclosure to be negative, 84.0 % of disclosers were accepted by their partners without negative consequences after disclosure. This study suggests that the existing support services ill prepares newly diagnosed HIV positive clients and hampers disclosure initiatives. Providing comprehensive support services and re-training peer educators may be crucial in creating a safe disclosure environment in Ghana.

Missed Opportunities along the Prevention of Mother-to-Child Transmission Services Cascade in South Africa: Uptake, Determinants, and Attributable Risk (the SAPMTCTE)

Objectives

We examined uptake of prevention of mother-to-child HIV transmission (PMTCT) services, predictors of missed opportunities, and infant HIV transmission attributable to missed opportunities along the PMTCT cascade across South Africa.

Methods

A cross-sectional survey was conducted among 4–8 week old infants receiving first immunisations in 580 nationally representative public health facilities in 2010. This included maternal interviews and testing infants’ dried blood spots for HIV. A weighted analysis was performed to assess uptake of antenatal and perinatal PMTCT services along the PMTCT cascade (namely: maternal HIV testing, CD4 count test/result, and receiving maternal and infant antiretroviral treatment) and predictors of dropout. The population attributable fraction associated with dropouts at each service point are estimated.

Results

Of 9,803 mothers included, 31.7% were HIV-positive as identified by reactive infant antibody tests. Of these 80.4% received some form of maternal and infant antiretroviral treatment. More than a third (34.9%) of mothers dropped out from one or more steps in the PMTCT service cascade. In a multivariable analysis, the following characteristics were associated with increased dropout from the PMTCT cascade: adolescent (<20 years) mothers, low socioeconomic score, low education level, primiparous mothers, delayed first antenatal visit, homebirth, and non-disclosure of HIV status. Adolescent mothers were twice (adjusted odds ratio: 2.2, 95% confidence interval: 1.5–3.3) as likely to be unaware of their HIV-positive status and had a significantly higher rate (85.2%) of unplanned pregnancies compared to adults aged ≥20 years (55.5%, p = 0.0001). A third (33.8%) of infant HIV infections were attributable to dropout in one or more steps in the cascade.

Conclusion

A third of transmissions attributable to missed opportunities of PMTCT services can be prevented by optimizing the uptake of PMTCT services. Identified risk factors for low PMTCT service uptake should be addressed through health facility and community-level interventions, including raising awareness, promoting women education, adolescent focused interventions, and strengthening linkages/referral-system between communities and health facilities.

Social support among HIV-positive and HIV-negative adolescents in Umlazi, South Africa: changes in family and partner relationships during pregnancy and the postpartum period

Background

Pregnancy is common among adolescents in South Africa, yet the social experiences of adolescents during the pregnancy and postpartum period remain understudied in this context. We aimed to explore how adolescent women’s discovery and disclosure of both their pregnancy and HIV status affected their relationships with family members and sexual partners, with a particular focus on whether and how support changed throughout this time period.

Methods

We conducted in-depth semi-structured interviews with 15 HIV-positive and HIV-negative adolescent women who were either pregnant or had delivered in the last 18 months from one urban clinic in Umlazi, South Africa. Interviews were audiotaped, transcribed, translated, and coded for analysis.

Results

Young women described stress and instability in their relationships with family and partners during pregnancy and the postpartum period, though prior to and during HIV-status disclosure women generally experienced less stress than in disclosing their pregnancy to family members and partners. After a destabilizing period immediately following pregnancy disclosure, families became and remained the primary source of material and emotional support for the young women. Women discussed heightened closeness with their partners during pregnancy, but few women had close relationships with their partners postpartum. Support experiences did not differ by HIV status.

Conclusion

Programs should be aware of the relative importance of pregnancy-related concerns over HIV-related concerns in this population of young women. Engaging family members is critical in ensuring social support for this population of young pregnant women, and in encouraging timely initiation of antenatal care.

Fertility desire among HIV-positive women in Tigray region, Ethiopia: implications for the provision of reproductive health and prevention of mother-to-child HIV transmission services

Background

There is growing recognition of the difficult reproductive decisions faced by HIV-positive women. Studies in both resource-constrained and developed countries have suggested that many HIV-positive women continue to desire children in spite of their understanding of the possible risks that HIV poses. This study investigates the factors associated with fertility desire among HIV-positive women in Tigray region, Ethiopia.

Methods

A cross-sectional survey was conducted among 964 HIV-positive women receiving HIV care in 12 health centers of Tigray region. In each health center, the number of study participants was allocated proportionally to the load of HIV-positive women in the chronic care clinics. A descriptive summary of the data and a logistic regression model were used to identify factors associated with fertility desire using odds ratios with a 95% confidence interval and P-value of 0.05.

Results

Four hundred and thirty nine (45.5%) of the participants reported a desire to have children in the future. Eighty six percent of the women had given birth to at least one live baby at the time of study, with the median number of live births being 2 (Inter quartile range = 1,3). Women in the age group of 15–24 years [AOR = 2.64(95% CI: 1.44, 4.83)] and 25–34 years [AOR = 2.37 (95% CI: 1.60, 2.4 3.50)] had higher fertility desire as compared to women in the age group of 35–49 years. Having no children [AOR = 25.76 (95% CI: 13.66, 48.56)], having one to two children [AOR = 5.14 (95% CI: 3.37, 7.84)] and disclosing HIV status to husband/sexual partner [AOR = 1.74 (95% CI: 1.11, 2.72)] were all independently associated with fertility desire.

Conclusions

Age, HIV disclosure status to husband/sexual partner, and relatively few live children were all found to influence HIV-positive women’s fertility desire. Programmers and policy makers should consider the effects of these factors for HIV-positive women as they develop HIV/AIDS interventions.

Implementing comprehensive prevention of mother-to-child transmission and HIV prevention for South African couples: study protocol for a randomized controlled trial

BACKGROUND

In rural South Africa, only two-thirds of HIV-positive pregnant women seeking antenatal care at community health centers took full advantage of 'prevention of mother-to-child transmission' (PMTCT) services in 2010. Studies generally support male involvement to promote PMTCT, but the nature and impact of that involvement is unclear and untested. Additionally, stigma, disclosure and intimate partner violence pose significant barriers to PMTCT uptake and retention in care, suggesting that male involvement may be 'necessary, but not sufficient' to reduce infant HIV incidence. This study expands on a successful United States President's Emergency Plan for AIDS Relief (PEPFAR)-supported PMTCT couples intervention pilot study conducted in the Mpumalanga province, targeting HIV-positive pregnant women and their partners, the primary objective being to determine whether male partner involvement plus a behavioral intervention will significantly reduce infant HIV incidence.

METHODS/DESIGN

The study follows a cluster randomized controlled design enrolling two cohorts of HIV-positive pregnant women recruited from 12 randomly assigned Community Health Centers (CHC) (six experimental, six control). The two cohorts will consist of women attending without their male partners (n = 720) and women attending with their male partners (n = 720 couples), in order to determine whether the influence of male participation itself, or combined with a behavioral PMTCT intervention, can significantly reduce infant HIV infection ante-, peri- and postnatally.

DISCUSSION

It is our intention to significantly increase PMTCT participation from current levels (69%) in the Mpumalanga province to between 90 and 95% through engaging women and couples in a controlled, six session ante- and postnatal risk-reducing and PMTCT promotion intervention addressing barriers to PMTCT (such as stigma, disclosure, intimate partner violence, communication, infant feeding practices and safer conception) that prevent women and men from utilizing treatment opportunities available to them and their infants. Based upon the encouraging preliminary results from our pilot study, successful CHC adoption of the program could have major public health policy implications for containing the epidemic among the most vulnerable populations in rural South Africa: HIV-positive pregnant women and their infants.

South Africans with recent pregnancy rarely know partner's HIV serostatus: implications for serodiscordant couples interventions

BACKGROUND

Implementation of safer conception strategies requires knowledge of partner HIV-serostatus. We recruited women and men in a high HIV-prevalence setting for a study to assess periconception risk behavior among individuals reporting HIV-serodiscordant partnerships. We report screening data from that study with the objective of estimating the proportion of individuals who are aware that they are in an HIV-serodiscordant relationship at the time of conception.

METHODS

We screened women and men attending antenatal and antiretroviral clinics in Durban, South Africa for enrollment in a study of periconception risk behavior among individuals with serodiscordant partners. Screening questionnaires assessed for study eligibility including age 18-45 years (for women) or at least 18 years of age (for men), pregnancy in past year (women) or partner pregnancy in the past 3 years (men), HIV status of partner for recent pregnancy, participant's HIV status, and infected partner's HIV status having been known before the referent pregnancy.

RESULTS

Among 2620 women screened, 2344 (90%) met age and pregnancy criteria and knew who fathered the referent pregnancy. Among those women, 963 (41%) did not know the pregnancy partner's HIV serostatus at time of screening. Only 92 (4%) reported knowing of a serodiscordant partnership prior to pregnancy. Among 1166 men screened, 225 (19%) met age and pregnancy criteria. Among those men, 71 (32%) did not know the pregnancy partner's HIV status and only 30 (13%) reported knowing of a serodiscordant partnership prior to pregnancy.

CONCLUSIONS

In an HIV-endemic setting, awareness of partner HIV serostatus is rare. Innovative strategies to increase HIV testing and disclosure are required to facilitate HIV prevention interventions for serodiscordant couples.

HIV-positive men's experiences with integrated family planning and HIV services in western Kenya: integration fosters male involvement

A growing body of evidence indicates that integrating family planning (FP) services into HIV care is effective at improving contraceptive uptake among HIV-positive women in resource-poor settings, yet little research has examined HIV-positive men's experiences with such integration. We conducted in-depth interviews with 21 HIV-positive men seeking care at HIV clinics in Nyanza, Kenya. All clinics were intervention sites for a FP/HIV service integration cluster-randomized trial. Grounded theory was used to code and analyze the data. Our findings highlight men's motivations for FP, reasons why men prefer obtaining their FP services, which include education, counseling, and commodities, at HIV care clinics, and specific ways in which integrated FP/HIV services fostered male inclusion in FP decision-making. In conclusion, men appear invested in FP and their inclusion in FP decision-making may bolster both female and male agency. Men's positive attitudes towards FP being provided at HIV care clinics supports the programmatic push towards integrated delivery models for FP and HIV services.

Desire for fertility among HIV-seroconcordant and -discordant couples in Lusaka, Zambia

Pregnancy rates and the desire to conceive are increasing among women living with HIV in Africa. However, attempts to conceive may increase the risk of HIV transmission or reinfection. A better understanding of factors influencing fertility desires would significantly contribute to programmes to meet the reproductive needs of women living with HIV. Using a couples-based approach, this paper explored fertility desires among HIV-seroconcordant and -discordant couples in Lusaka, Zambia. Participants were 208 heterosexual couples recruited from community health clinics and their respective catchment areas. Couples completed assessments on demographics, condom use, relationship quality and communication. Desire for children was often shared among couple members, and the strongest predictor of participants' desire for children was having a partner who wanted children. Additionally, the number of children participants had, their own reports of positive communication, and their partner's HIV serostatus influenced reproductive desires. Results support the involvement of both couple members in pre-conception counselling and pregnancy planning interventions. The inclusion of both partners may be a more effective strategy to respond to the reproductive needs of couples affected by HIV, enabling them to safeguard the health of both partners and infants.

Sexual HIV risk behaviour and associated factors among pregnant women in Mpumalanga, South Africa

Background

The HIV risk increases during pregnancy. The elevated risk of HIV acquisition in pregnant women may be explained by behavioural and other factors. The aim of this study was to assess sexual HIV risk behaviour and its associated factors among pregnant women in Mpumalanga, South Africa.

Methods

A cross-sectional study was conducted among 1 502 pregnant women (age range 18–47 years, mean age 26.6 years, standard deviation (SD) 6.1, and the mean gestational age was 6.5 months (SD 1.6). Antenatal women were selected, using systematic sampling from 63 primary care clinics and community health centres in Nkangala District. Data were collected by using a structured questionnaire and multivariate logistic regression analysis was used.

Results

The majority (63%) of the participants had never used a condom with their primary sexual partner in the past 3 months, 60% were not aware of the HIV status of their sexual partner, 7.6% had a casual sexual partner in the past 3 months, 20% had two or more sexual partners in the past 12 months and 17.3% reported to have been diagnosed with a sexually transmitted infection (STI) (other than HIV) in the past 12 months. The various HIV risk behaviours were predicted, by being single and alcohol use for multiple sexual partners; by fewer antenatal visits, being HIV negative and not having used alcohol for lack of condom use; by being HIV positive, having experienced physical partner violence and psychological distress for having been diagnosed with a sexually transmitted infection (other than HIV); and by lower education, unplanned pregnancy, non-antenatal care attendance by expectant father, the belief that antiretrovirals can cure HIV and being HIV positive for having a partner with HIV positve or unknown status.

Conclusion

High levels of sexual HIV risk behaviour were found during pregnancy. Pregnant women need to be informed of their increased risk of HIV and the importance of sexual HIV risk reduction including the use of condoms throughout pregnancy.

Barriers to male-partner participation in programs to prevent mother-to-child HIV transmission in South Africa

Efforts to prevent mother-to-child HIV transmission (PMTCT) in sub-Saharan Africa have focused overwhelmingly on women, to the unintended exclusion of their male partners. A cross-sectional study was conducted in Tshwane, South Africa, to determine barriers to male-partner participation during PMTCT. In-depth interviews were conducted with 124 men whose partners had recently been pregnant, and five focus group discussions were held with physicians, nurses, HIV counselors, and community representatives. Qualitative analysis revealed that while most fathers believed that HIV testing is an important part of preparing for fatherhood, there are formidable structural and psychosocial barriers: the perception of clinics as not "male-friendly," a narrow focus on HIV testing instead of general wellness, and a lack of expectations and opportunities for fathers to participate in health care. Coupled with more family-oriented approaches to PMTCT, measurable improvements in the way that male partners are invited to and engaged in HIV prevention during pregnancy can help PMTCT programs to achieve their full potential.
