Correlates of antiretroviral coverage for prevention of mother-to-child transmission of HIV in sub-Saharan Africa

ABSTRACT

Antiretroviral (ARV) drugs are effective in the prevention of mother-to-child transmission of HIV (PMTCT), however many sub-Saharan African countries are yet to achieve universal ARV coverage among pregnant women living with HIV. This study examined factors associated with ARV coverage for PMTCT in 41 sub-Saharan Africa countries. Country-level aggregated data were obtained from the Joint United Nations Programme on HIV/AIDS, World Health Organization, and United Nations Children’s Fund. Using Spearman’s rho and point-biserial correlation, we conducted bivariate analyses between ARV coverage for PMTCT and the following variables: stigma, antenatal care (ANC) uptake, institutional delivery, community delivery of ARV drugs, number of HIV testing and counselling (HTC) facilities, and density of skilled health workers. We also performed a multivariate median regression with the significant correlates. P?<?.05 was considered statistically significant for all the tests. The median ARV coverage for PMTCT was 76% (IQR: 55–85%). ARV coverage for PMTCT was significantly associated with HTC facilities (r?=?0.46, p?=?.004), institutional delivery (r?=?0.48, p?=?.002), ANC uptake: at least one visit (r?=?0.54, p?=?.001), and stigma (r=?0.52, p?=?.003). In the multivariate analysis, only stigma remained statistically significant (β?=??0.6, 95% CI?=??1.13, ?0.07, p?=?.03). To eliminate perinatal transmission of HIV in sub-Saharan Africa, interventions that will address stigma-related barriers to uptake of PMTCT services are needed. More research on country-specific population-level correlates of ARV coverage for PMTCT is recommended.     

Pregnant Women Living with HIV (WLH) Supported at Clinics by Peer WLH: A Cluster Randomized Controlled Trial

Throughout Africa, Peer Mentors who are women living with HIV (WLH) are supporting pregnant WLH at antenatal and primary healthcare clinics (McColl in BMJ 344:e1590, 2012). We evaluate a program using this intervention strategy at 1.5 months post-birth. In a cluster randomized controlled trial in KwaZulu-Natal, South Africa, eight clinics were randomized for their WLH to receive either: standard care (SC), based on national guidelines to prevent mother-to-child transmission (4 clinics; n = 656 WLH); or an enhanced intervention (EI; 4 clinics; n = 544 WLH). The EI consisted of four antenatal and four postnatal small group sessions led by Peer Mentors, in addition to SC. WLH were recruited during pregnancy and 70 % were reassessed at 1.5 months post-birth. EI’s effect was ascertained on 16 measures of maternal and infant well-being using random effects regressions to control for clinic clustering. A binomial test for correlated outcomes evaluated EI’s overall effectiveness. Among EI WLH reassessed, 87 % attended at least one intervention session (mean 4.1, SD 2.0). Significant overall benefits were found in EI compared to SC using the binomial test. However, it is important to note that EI WLH were significantly less likely to adhere to ARV during pregnancy compared to SC. Secondarily, compared to SC, EI WLH were more likely to ask partners to test for HIV, better protected their infants from HIV transmission, and were less likely to have depressed mood and stunted infants. Adherence to clinic intervention groups was low, yet, there were benefits for maternal and infant health at 1.5 months post-birth.     

Risk factors for postpartum depression in women living with HIV attending prevention of mother-to-child transmission clinic at Kenyatta National Hospital,Nairobi

Mothers with HIV are at high risk of a range of psychosocial issues that may impact HIV disease progression for themselves and their children. Stigma has also become a substantial barrier to accessing HIV/AIDS care and prevention services. The study objective was to determine the prevalence and severity of postpartum depression (PPD) among women living with HIV and to further understand the impact of stigma and other psychosocial factors in 123 women living with HIV attending prevention of mother-to-child transmission (PMTCT) clinic at Kenyatta National Hospital located in Nairobi, Kenya. We used the Edinburgh Postnatal Depression Scale and HIV/AIDS Stigma Instrument – PLWHA (HASI – P). Forty-eight percent (N?=?59) of women screened positive for elevated depressive symptoms. Eleven (9%) of the participants reported high levels of stigma. Multivariate analyses showed that lower education (OR?=?0.14, 95% CI [0.04–0.46], p?=?.001) and lack of family support (OR?=?2.49, 95% CI [1.14–5.42], p?=?.02) were associated with the presence of elevated depressive symptoms. The presence of stigma implied more than ninefold risk of development of PPD (OR?=?9.44, 95% CI [1.132–78.79], p?=?.04). Stigma was positively correlated with an increase in PPD. PMTCT is an ideal context to reach out to women to address mental health problems especially depression screening and offering psychosocial treatments bolstering quality of life of the mother–baby dyad.     

HIV Knowledge and Sexual Risk Behavior Among Pregnant Couples in South Africa: The PartnerPlus Project

In sub-Saharan Africa, 60 % of people living with HIV are women and most are of childbearing age. Alarmingly, seroconversion rates during pregnancy are high and increase as pregnancy progresses, highlighting the importance of increasing HIV-knowledge among pregnant women and their partners. This study compared sexual risk behavior, HIV knowledge and condom use pre- to post-partum among South African couples (n = 239 couples) randomly assigned to an intervention or an enhanced standard of care with the PMTCT protocol at rural community health antenatal clinics. Consistent condom use and HIV-related knowledge increased baseline to post-intervention and was maintained at long term follow up post-partum among participants in the intervention condition. HIV knowledge mediated the relationship between the intervention and consistent condom use. Results from this pilot study provide support for the integration of HIV risk reduction interventions for both women and men into existing PMTCT services during and following pregnancy.     

Predictors of postpartum HIV care engagement for women enrolled in prevention of mother-to-child transmission (PMTCT) programs in Tanzania

Prevention of mother-to-child transmission of HIV (PMTCT) is a foundational component of a comprehensive HIV treatment program. In addition to preventing vertical transmission to children, PMTCT is an important catch-point for universal test-and-treat strategies that can reduce community viral load and slow the epidemic. However, systematic reviews suggest that care engagement in PMTCT programs is sub-optimal. This study enrolled a cohort of 200 women initiating PMTCT in Kilimanjaro, Tanzania, and followed them to assess HIV care engagement and associated factors. Six months after delivery, 42/200 (21%) of participants were identified as having poor care engagement, defined as HIV RNA >200?copies/mL or, if viral load was unavailable, being lost-to-follow-up in the clinical records or self-reporting being out of care. In a multivariable risk factor analysis, younger women were more likely to have poor postpartum care engagement; with each year of age, women were 7% less likely to have poor care engagement (aRR: 0.93; 95% CI: 0.89, 0.98). Additionally, women who had told at least one person about their HIV status were 47% less likely to have poor care engagement (aRR: .53; 95% CI: 0.29, 0.97). Among women who entered antenatal care with an established HIV diagnosis, those who were pregnant for the first time had increased risk of poor care engagement (aRR 4.16; 95% CI 1.53, 11.28). The findings suggest that care engagement remains a concern in PMTCT programs, and must be addressed to realize the goals of PMTCT. Comprehensive counseling on HIV disclosure, along with community-based stigma reduction programs to provide a supportive environment for people living with HIV, are crucial to address barriers to care engagement and support long-term treatment. Women presenting to antenatal care with an established HIV status require support for care engagement during the crucial period surrounding childbirth, particularly those pregnant for the first time.     

Risk and protective factors of posttraumatic stress disorder among African American women living with HIV

We sought to examine risk and protective factors for Posttraumatic Stress Disorder (PTSD) among African American women living with HIV. This is a cross-sectional analysis of baseline data from a randomized trial of an HIV stigma reduction intervention. We examined data from two-hundred and thirty-nine African American women living with HIV. We examined whether age, marital status, level of education, internalized HIV-related stigma, and social support as potential protective and risk factors for PTSD symptoms using logistic regression. We analyzed bi-variate associations between each variable and PTSD symptoms, and constructed a multivariate logistic regression model adjusting for all variables. We found 67% reported clinically significant PTSD symptoms at baseline. Our results suggest that age, education, and internalized stigma were found to be associated with PTSD symptoms (p?相似文献   

Effect of a Community Popular Opinion Leader HIV/STI Intervention on Stigma in Urban,Coastal Peru

Evaluating interventions that reduce HIV stigma may help to craft effective stigma-reduction programs. This study evaluates the effects of a community popular opinion leader HIV/STI intervention on stigma in urban, coastal Peru. Mixed effects modeling was used to analyze data on 3,049 participants from the Peru site of the NIHM collaborative trial. Analyses looked at differences between the comparison and intervention groups on a stigma index from baseline to 12- and 24-month follow-up. Sub-analyses were conducted on heterosexual-identified men (esquineros), homosexual-identified men (homosexuales), and socially marginalized women (movidas). Compared to participants in the comparison group, intervention participants reported lower levels of stigma at 12- and 24-month follow-up. Similar results were found within esquineros and homosexuales. No significant differences were found within movidas. Findings suggest that interventions designed to normalize HIV prevention behaviors and HIV communication can reduce HIV-related stigma and change community norms.     

HIV and depression in Eastern Nigeria: The role of HIV-related stigma

To examine the prevalence of depression among HIV-positive patients in Eastern Nigeria and to explore its association with HIV-related stigma. One hundred and five patients with a diagnosis of HIV attending HIV clinics in Eastern Nigeria completed a questionnaire consisting of demographic and health background, the Patients Health Questionnaire (to measure depression) and the Berger HIV stigma scale. As many as 33.3% of participants were considered depressed. Depression was positively correlated with overall stigma score with further analysis finding a positive correlation with all four subscales of the questionnaire (personalised stigma, disclosure, negative self-image and public attitudes). Individuals experiencing more side effects of HIV treatment were also rated as more depressed. A regression analysis found that negative self-image and number of treatment side effects were significant predictors of depression. Depression is positively associated with HIV-related stigma in this sample in Eastern Nigeria. As both stigma and depression have been shown to have a negative impact on quality of life for those with HIV, health professionals working to support them should be aware of the impact of stigma on risk of depression. Screening for both HIV-related stigma and depression would be an important intervention to promote both physical and psychological well-being amongst HIV-positive patients in Eastern Nigeria.     

Women's choices regarding HIV testing,disclosure and partner involvement in infant feeding and care in a rural district of Malawi with high HIV prevalence

The influence of HIV-related stigma on women's choices with regard to HIV testing, disclosure and partner involvement in infant feeding and care is not well understood in rural Malawi but may influence the risk of vertical HIV transmission and infant health. In a study of HIV-infected and -uninfected women in 20 rural locations in Zomba District, Malawi, mothers were questioned at 18–20 months post-partum about these issues. Ten per cent of women claimed unknown HIV status in labour so HIV testing should be routinely offered in Labour & Delivery wards. HIV-infected women were somewhat less likely to disclose to their partners than HIV-uninfected women (89 and 97%, respectively; p = 0.007) or to be cohabiting with partners during pregnancy (74 and 86%, respectively; p = 0.03). Partners of women were less inclined to disclose their HIV testing or HIV status (49 and 66% of partners of HIV-infected and -uninfected women, respectively). Greater partner testing and disclosure may improve prevention of mother to child transmission of HIV (PMTCT) in this population. A majority of women were inclined to make feeding decisions on their own, whereas most felt that other health-related decisions should also involve the father. Most mothers believe that exclusive breast feeding (EBF) is the best infant feeding method (for the first six months) but it was actually practiced by a minority of women (20% of HIV-infected and 5% of HIV-uninfected mothers; p = 0.01). EBF needs systematic support in order to be practised.     

Reducing HIV stigma among healthcare providers in India using a partly tablet-administered intervention: the DriSti trial

ABSTRACT

HIV stigma has long been recognized as a significant barrier in the worldwide fight against HIV. Across cultures, stigma has been shown to cause psychological distress and act as a barrier to engagement in care. Health professionals can serve as a crucial source of HIV stigma, with drivers that include fears and transmission misconceptions and pre-existing negative attitudes towards marginalized groups. To increase their impact, stigma reduction interventions need to be scalable and sustainable as well as adaptable to different cultural contexts. The DriSti intervention was designed to meet these needs through an easily adaptable, mostly tablet-administered, interactive intervention delivered to ward staff (n?=?1,557) and nursing students (n?=?1,625) in 62 Indian institutions, using a cRCT design, with wait-list controls. Six-month outcome analyses, showed significant reductions in misconceptions (p?<?.001) and worry about acquiring HIV at work (p?<?.001). Intervention participants also reported significantly greater reductions in endorsement of coercive policies (p?<?.001) and in the number of situations in which they intended to discriminate against PLWH (p?<?.001) than control participants. This brief, scaleable intervention could be adapted for similar populations in the region, using different mHealth platforms and thus has important implications for current global stigma reduction initiatives and training curricula.     

HIV knowledge,disclosure and sexual risk among pregnant women and their partners in rural South Africa

Abstract

Partner involvement has been deemed fundamental for the prevention of mother-to-child transmission (PMTCT) of HIV, although it remains difficult to achieve. This study aimed to explore the attitudes and behaviours of pregnant women and their partners who participated in a behavioural risk reduction intervention in six community health centres in the Mpumalanga province of South Africa. Qualitative methods only were used in this study. Women and their partners took part in four gender-concordant groups that addressed HIV, PMTCT, disclosure of HIV status and safer sex practices. The results indicate that men value and understand the importance of being involved in women's reproductive health, although some components of the PMTCT programme such as condom use were still met with some resistance. Participants demonstrated high levels of HIV- and sexually transmitted infection-related knowledge. Men lacked knowledge about PMTCT but were interested in acquiring information so that they could support their partners. All groups highlighted the emotional and physical benefits of disclosing one's HIV status. The involvement of men in antenatal care has the potential to prevent women from becoming infected with HIV both during pregnancy and post-partum when they are more vulnerable to infection and have a high risk of transmission to the infant. There is a need for interventions that focus on both increasing male involvement and promoting condom use during pregnancy.     

Testing our FAITHH: HIV stigma and knowledge after a faith-based HIV stigma reduction intervention in the Rural South

Eliminating racial/ethnic HIV disparities requires HIV-related stigma reduction. African-American churches have a history of addressing community concerns, including health issues, but may also contribute to stigma. We developed and pilot tested a faith-based, anti-stigma intervention with 12 African-American churches in rural Alabama. We measured HIV-related stigma held by 199 adults who participated in the intervention (individual-level) and their perception of stigma among other congregants (congregational-level). Analyses of pre- and post-assessments using a linear mixed model showed the anti-stigma intervention group reported a significant reduction in individual-level stigma compared with the control group (mean difference: ?.70 intervention vs. ?.16 control, adjusted p?相似文献   

Influences on Exclusive Breastfeeding Among Rural HIV-Infected South African Women: A Cluster Randomized Control Trial

South African guidelines for prevention-of-mother-to-child-transmission (PMTCT) of HIV emphasize exclusive breastfeeding (EBF). This study examined the impact of a PMTCT intervention and male involvement on EBF. In a two-phase cluster-randomized trial, rural South African community health centers were randomized to offer HIV-infected pregnant women PMTCT standard of care plus either: a behavioral PMTCT intervention, or a time-equivalent attention-control condition. Phase 1 women had non-participating male partners; Phase 2 women had participating partners. Pregnant women (n?=?1398) were assessed on HIV stigma, disclosure of HIV status to partner, male involvement, and family planning knowledge. Feeding practices were assessed 6 weeks postpartum (56% retained). Reduced depressive symptomatology predicted EBF 6 weeks postpartum, adjusting for attrition (AOR?=?0.954, p?=?0.001). Neither male involvement in antenatal care, phase, HIV stigma, disclosure, nor family planning knowledge predicted EBF. Future studies and perinatal care should address depression, which has important implications for infant health.     

Increasing HIV testing among pregnant women in Nigeria: evaluating the traditional birth attendant and primary health center integration (TAP-In) model

Engaging Traditional Birth Attendants (TBAs) may be critical to preventing mother-to-child transmission of HIV (PMTCT) in Nigeria. We integrated TBAs into Primary Health Centers (PHCs) and provided the TBAs with HIV counseling and testing (HCT) training for PMTCT (TAP-In). The purpose of this study was to evaluate the impact of TAP-In on HCT uptake among pregnant women. A quasi-experimental design was used for this study. Twenty PHCs were assigned to the intervention group that integrated TAP-In and 20 were assigned to the control group. Data were collected six months prior to the initiation of TAP-In and six months post, using antenatal clinic registries. Intervention PHCs more than doubled the number of pregnant women who received HCT in their catchment area post TAP-In while control PHCs had no significant change. After initiating TAP-In, intervention PHCs provided almost three times more HCT than the control PHCs (p?相似文献   

Reducing the risk of HIV infection during pregnancy among South African women: A randomized controlled trial

Mpumalanga Province, South Africa has one of the highest HIV/AIDS diagnosis rates among pregnant women (~29.4%). This study sought to enhance male involvement in pregnancy to increase HIV disclosure, sexual communication, HIV knowledge and reduce unprotected sex. Participants attending Antenatal Clinics (ANC) completed HIV counseling and testing and were enrolled with male partners (n=239 couples, 478 individuals). Twelve ANCs were randomly assigned to provide a prevention of mother-to-child transmission (PMTCT) intervention or the standard of care, health education sessions plus PMTCT. Participants were assessed at baseline and post-intervention (approximately 6–8 weeks post-baseline) on demographics, sexual behavior, HIV-related knowledge, and conflict resolution strategies. Experimental participants increased HIV knowledge, use of negotiation, and decreased intimate partner violence. Additionally, they were more likely to have increased condom use from baseline to post-intervention (OR=5.1, 95% CI=[2.0, 13.3]). Seroconversions in the control condition exceeded experimental (6 vs. 0). HIV serostatus disclosure to partner did not increase over time for men or women within the experimental or control condition. Male involvement in pregnancy may be an important strategy to reduce sexual risk behavior and HIV transmission. Results support the utility of group interventions to enhance communication and HIV knowledge among pregnant couples.     

Examining HIV Stigma,Depression, Stress,and Recent Stimulant Use in a Sample of Sexual Minority Men Living with HIV: An Application of the Stigma and Substance Use Process Model

Sexual minority men (SMM) with HIV are disproportionately impacted by stigma and mental health disorders. Guided by the Stigma and Substance Use Process Model, we evaluated how HIV stigma impacts mental health outcomes among SMM with HIV. Data were drawn from Thrive With Me, an RCT of an mHealth intervention targeting ART adherence among SMM with HIV. Path analyses tested the relationships between HIV stigma, depression, stress, and recent stimulant use. Overall, 49.1% (194/401) had depression symptoms, 68.8% (276/401) had moderate-to-high stress, and 28.1% (111/401) had detectable stimulant use in urine samples at baseline. In path analyses, baseline internalized HIV stigma was associated with depression and stress 5-months post-baseline and enacted stigma was associated with recent stimulant use 11-months post-baseline. We identified internalized and enacted HIV stigma, but not anticipated stigma, as potentially important intervention targets for stimulant use, depression, and stress among SMM with HIV.

HIV stigma intervention in a low-HIV prevalence setting: a pilot study in an Egyptian healthcare facility

This pilot study is the first to evaluate stigma-reduction intervention in a healthcare setting in Egypt and in the Middle East and North Africa region. It also contributes to knowledge on how to address stigma in low-HIV prevalence settings. A quasi-experimental study design was used to evaluate the effect of anti-HIV stigma intervention in one hospital in Egypt. A control hospital was selected and matched to the intervention hospital by type, size and location. The intervention focused on HIV-related stigma, infection control and medical ethics. Stigma was measured at baseline and at three months post-intervention. A standardized, 10-point scale was developed to measure stigmatizing attitudes and fear-based stigma among participants. Comparisons of overall and job-stratified stigma scores were made across the intervention and control hospitals, before and after the intervention, using two-sample t-test and multivariate regression analysis. Mean stigma scores did not reveal significant differences between the intervention and control hospitals at baseline. After intervention, the overall value-based and fear-based stigma scores were significantly lower in the intervention hospital compared to the control hospital (2.1 and 1.1 compared to 3.8 and 3.2, respectively; p?相似文献   

The Regai Dzive Shiri Project: a cluster randomised controlled trial to determine the effectiveness of a multi-component community-based HIV prevention intervention for rural youth in Zimbabwe--study design and baseline results

Objective To assess the effectiveness of a community‐based HIV prevention intervention for adolescents in terms of its impact on (1) HIV and Herpes simplex virus type 2 (HSV‐2) incidence and on rates of unintended pregnancy and (2) reported sexual behaviour, knowledge and attitudes. Methods Cluster randomised trial of a multi‐component HIV prevention intervention for adolescents based in rural Zimbabwe. Thirty communities were selected and randomised in 2003 to early or deferred intervention implementation. A baseline bio‐behavioural survey was conducted among 6791 secondary school pupils (86% of eligibles) prior to intervention implementation. Results Baseline prevalences were 0.8% (95% CI: 0.6–1.0) for HIV and 0.2% (95% CI: 0.1–0.3%) for HSV‐2. Four girls (0.12%) were pregnant. There was excellent balance between study arms. Orphans who made up 35% of the cohort were at increased risk of HIV [age–sex adjusted odds ratio 3.4 (95% CI: 1.7–6.5)]. 11.9% of young men and 2.9% of young women reported that they were sexually active (P < 0.001); however, there were inconsistencies in the sexual behaviour data. Girls were less likely to know about reproductive health issues than boys (P < 0.001) and were less likely to have used and to be able to access condoms (P < 0.001). Conclusion This is one of the first rigorous evaluations of a community‐based HIV prevention intervention for young people in southern Africa. The low rates of HIV suggest that the intervention was started before this population became sexually active. Inconsistency and under‐reporting of sexual behaviour re‐emphasise the importance of using externally validated measures of sexual risk reduction in behavioural intervention studies.
