RESUMEN
Mozambique has one of the world's highest HIV/AIDS burdens. Despite significant investment in HIV care and treatment, pregnant and lactating women's retention in care remains suboptimal. One reason for poor maternal retention is lack of male partner support. We tested an interventional couple-based HIV care and treatment, including joint clinical appointments and couple-based educational and support sessions provided by a health counselor and peer educators, respectively. Healthcare providers delivering care for seroconcordant individuals were interviewed regarding their perspectives on facilitators and barriers to the couple-based intervention implementation. Analysis of interview responses was done using MAXQDA. Results pertaining to providers' perspectives on implementation and intervention characteristics were organized, interpreted, and contextualized using the Consolidated Framework for Implementation Research (CFIR 2.0), while providers' suggestions for improvements were coded and organized apart from CFIR. Providers felt the intervention was largely compatible with the local culture, and offered a significant advantage over standard individual-based care by facilitating patient follow-up and reducing wait times by prioritizing couples for services. They also believed it facilitated HIV treatment access through the provision of couple-based counseling that encouraged supportive behaviors towards retention. However, providers reported insufficient privacy to deliver couple-based care at some health facilities and concerns that women in difficult relationships may struggle to meaningfully participate. They suggested providing sessions in alternate clinic settings and offering a limited number of women-only visits. The facilitators and barriers described here contribute to informing the design and implementation of future couple-based interventions to improve HIV care for seroconcordant expectant couples.

Inverse probability weighting (IPW), a well-established method of controlling for confounding in observational studies with binary exposures, has been extended to analyses with continuous exposures. Methods developed for continuous exposures may not apply when the exposure is quasicontinuous because of irregular exposure distributions that violate key assumptions. We used simulations and cluster-randomized clinical trial data to assess 4 approaches developed for continuous exposures-ordinary least squares (OLS), covariate balancing generalized propensity scores (CBGPS), nonparametric covariate balancing generalized propensity scores (npCBGPS), and quantile binning (QB)-and a novel method, a cumulative probability model (CPM), in quasicontinuous exposure settings. We compared IPW stability, covariate balance, bias, mean squared error, and standard error estimation across 3,000 simulations with 6 different quasicontinuous exposures, varying in skewness and granularity. In general, CBGPS and npCBGPS resulted in excellent covariate balance, and npCBGPS was the least biased but the most variable. The QB and CPM approaches had the lowest mean squared error, particularly with marginally skewed exposures. We then successfully applied the IPW approaches, together with missing-data techniques, to assess how session attendance (out of a possible 15) in a partners-based clustered intervention among pregnant couples living with human immunodeficiency virus in Mozambique (2017-2022) influenced postpartum contraceptive uptake.

Approximately 15% of people with HIV in sub-Saharan Africa have comorbid depression, which impacts treatment outcomes. We describe predictors of baseline depressive symptoms in 1079 female and 1079 male participants in a cluster-randomized trial in Zambézia Province, Mozambique from November 2017 to December 2020. We modeled each partners' depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]) using proportional odds models adjusted for enrollment date, age, body mass index [BMI], partner's PHQ-9 score, district, relationship status, education, occupation, WHO HIV clinical stage, and antiretroviral therapy use history. A post hoc analysis assessed covariate-adjusted rank correlation between partner depressive symptoms. Females were younger than males (median 23 vs. 28 years) and more likely to report no education (20.7% vs. 7.9%). Approximately 10% screened positive for depression (PHQ-9 score ≥ 10). Partner depressive symptoms were predictive of higher participant PHQ-9 scores. A male partner PHQ-9 score of 10 (versus 5) increased the odds that the female partner would have a higher PHQ-9 score (adjusted odds ratio: 7.25, 95% Confidence Interval [CI]: 5.43-9.67). Partner PHQ-9 scores were highly correlated after covariate adjustment (Spearman's rho 0.65, 95% CI 0.57-0.72). Interventions aimed to reduce depressive symptoms and improve HIV-related outcomes during pregnancy should address both partners' depressive symptoms.

Mozambique introduced guidelines for integrated gender-based violence (GBV) services in 2012. In 2017, we trained providers on empathetic and supportive services to GBV survivors and introduced home-based services for survivors who are loss-to-follow up. Rate ratios of clinic visits were compared before and after intervention initiation, using exact significance tests. Data of 1,806 GBV survivors were reviewed, with a total of 2005 events. The median age was 23 years (IQR 17-30) and 89% were women. Among those reporting violence, 69% reported physical violence, 18% reported sexual violence (SV), and 12% reported psychological violence. Rates of care-seeking behavior were higher in the intervention period (rate ratio 1.31 [95%CI: 1.18-1.46]); p < 0.01. Among those eligible for post-exposure prophylaxis (PEP), 94% initiated PEP. Uptake of HIV retesting improved in percentage points by 34% (14% to 48%), 34% (8% to 42%) and 26% (5% to 31%) at 1-, 3- and 6-months, respectively. The intervention led to an increase in the rate of GBV survivors seeking health care services, and improved rates of follow-up care among SV survivors initiating PEP. Strengthening of PEP adherence counseling remains crucial for improving GBV services.

BACKGROUND: The under-5 mortality rate (U5MR) is an important metric of child health and survival. Country-level estimates of U5MR are readily available, but efforts to estimate U5MR subnationally have been limited, in part, due to spatial misalignment of available data sources (e.g., use of different administrative levels, or as a result of historical boundary changes). METHODS: We analyzed all available complete and summary birth history data in surveys and censuses in six countries (Bangladesh, Cameroon, Chad, Mozambique, Uganda, and Zambia) at the finest geographic level available in each data source. We then developed small area estimation models capable of incorporating spatially misaligned data. These small area estimation models were applied to the birth history data in order to estimate trends in U5MR from 1980 to 2015 at the second administrative level in Cameroon, Chad, Mozambique, Uganda, and Zambia and at the third administrative level in Bangladesh. RESULTS: We found substantial variation in U5MR in all six countries: there was more than a two-fold difference in U5MR between the area with the highest rate and the area with the lowest rate in every country. All areas in all countries experienced declines in U5MR between 1980 and 2015, but the degree varied both within and between countries. In Cameroon, Chad, Mozambique, and Zambia we found areas with U5MRs in 2015 that were higher than in other parts of the same country in 1980. Comparing subnational U5MR to country-level targets for the Millennium Development Goals (MDG), we find that 12.8% of areas in Bangladesh did not meet the country-level target, although the country as whole did. A minority of areas in Chad, Mozambique, Uganda, and Zambia met the country-level MDG targets while these countries as a whole did not. CONCLUSIONS: Subnational estimates of U5MR reveal significant within-country variation. These estimates could be used for identifying high-need areas and positive deviants, tracking trends in geographic inequalities, and evaluating progress towards international development targets such as the Sustainable Development Goals.

BACKGROUND: Follow-up of HIV-exposed children for the delivery of prevention of mother-to-child transmission services and for early diagnosis and treatment of HIV infection is critical to their survival. Despite efforts, uptake of postnatal care for these children remains low in many sub-Saharan African countries. METHODS: A qualitative study was conducted in three provinces in Mozambique to identify motivators and barriers to improve uptake of and retention in HIV prevention, care and treatment services for HIV-exposed and HIV-infected children. Participant recommendations were also gathered. Individual interviews (n = 79) and focus group discussions (n = 32) were conducted with parents/caregivers, grandmothers, community leaders and health care workers. Using a socioecological framework, the main themes identified were organized into multiple spheres of influence, specifically at the individual, interpersonal, institutional, community and policy levels. RESULTS: Study participants reported factors such as seeking care outside of the conventional health system and disbelief in test results as barriers to use of HIV services. Other key barriers included fear of disclosure at the interpersonal level and poor patient flow and long waiting time at the institutional level. Key facilitators for accessing care included having hope for children's future, symptomatic illness in children, and the belief that health facilities were the appropriate places to get care. CONCLUSIONS: The results suggest that individual-level factors are critical drivers that influence the health-seeking behavior of caregivers of HIV-exposed and HIV-infected children in Mozambique. Noted strategies are to provide more information and awareness on the benefits of early pediatric testing and treatment with positive messages that incorporate success stories, to reach more pregnant women and mother-child pairs postpartum, and to provide counseling during tracing visits. Increasing uptake and retention may be achieved by improving patient flow at the institutional level at health facilities, by addressing concerns with family decision makers, and by working with community leaders to support the uptake of services for HIV-exposed children for essential preventive care.

Introduction: This study recognized the lack of information regarding recruitment and retention factors associated with implementing HIV vaccine trials from the perspective of de facto participants. It aimed to describe the motives and experiences of 31 young adults who participated in a phase II HIV vaccine clinical trial conducted in Maputo, Mozambique. Methods: This was an ancillary study with a mixed-method approach that employed a convergent design, combining both quantitative and qualitative methodologies. Data collection involved questionnaire surveys, in-depth interviews, and focus group discussions. Participants were assessed before and after learning whether they received the experimental vaccine or placebo. Thematic analysis was used for qualitative data, while descriptive analysis and statistical tests such as Fischer's test and McNemar's exact test were applied to quantitative data. The study also utilized the Health Belief Model to understand the decision-making process of participating in an HIV vaccine study. Results: Most of our participants were young females, single, with limited financial resources. Participants joined the trial with the belief that they had a unique opportunity to help the fight against HIV and contribute to the research for the discovery of an HIV vaccine. Positive experiences related to trial participation include gaining knowledge about HIV and personal health and receiving risk reduction counseling. Participants reported blood collection as a negative experience and that they suffered social harm because of trial participation. Participants felt abandoned after the trial ended. Conclusion: Preventive HIV vaccine trials should integrate a social-behavioral component to assess reasons for participation and refusal in real-time. Providing ongoing personal attention is crucial for young individuals who have committed 1-2 years to trial participation, extending beyond the trial period. Implementing tailored strategies for HIV risk assessment and reduction during and after the trial is essential. Addressing these factors can enhance preventive HIV vaccine trial implementation.
RESUMEN
INTRODUCTION: Patient satisfaction with clinical services can have an effect on retention in HIV care and adherence to antiretroviral therapy. This study assessed patient satisfaction and its association with retention and viral suppression in Zambézia Province, Mozambique. METHODS: Monthly exit interviews with persons living with HIV were completed from August 2017-January 2019 in 20 health facilities; clinical data were extracted from medical records. Regression analyses assessed the effect of satisfaction scores on retention and viral suppression, adjusting for age, sex, education, civil status, time on treatment, and site. Satisfaction scores were correlated with time spent at health facilities using generalized linear regression models. RESULTS: Data from 4388 patients were analyzed. Overall median satisfaction score was 75% (IQR 53%-84%); median time spent at facilities (from arrival until completion of clinical services) was 2h54min (IQR 1h48min-4h). Overall satisfaction score was not associated with higher odds of retention or viral suppression, but association was seen between satisfaction regarding attention given to patient and respect and higher odds of viral suppression. Patient satisfaction was negatively associated with time spent in facility (Spearman's correlation -0.63). Increased time spent at facility (from 1 to 3 hours) was not associated with lower retention in care (OR 0.72 [95%CI:0.52-1.01] and 0.83 [95%CI: 0.63-1.09] at 6- and 12-months, respectively), nor with a lower odds of viral suppression (OR 0.96 [95%CI: 0.71-1.32]). CONCLUSIONS: Strategies to reduce patient wait times at the health facility warrant continued prioritization. Differentiated models of care have helped considerably, but novel approaches are still needed to further decongest crowded health facilities. In addition, a good client-provider communication and positive attitude can improve patient satisfaction with health services, with an overall improved retention.

INTRODUCTION: There is evidence that a supportive male partner facilitates maternal HIV testing during pregnancy, increases maternal antiretroviral therapy initiation and adherence, and increases HIV-free infant survival. Most male partner engagement clinical strategies have focused on increasing uptake of couple-based HIV testing and counseling. We delivered a couple-based care and treatment intervention to improve antiretroviral therapy adherence in expectant couples living with HIV. METHODS: We implemented a cluster randomized controlled trial for seroconcordant couples living with HIV, comparing retention (using a patient's medication possession ratio) in HIV care for a couple-based care and treatment intervention vs. standard of care services in rural Mozambique. The intervention included couple-based treatment, couple-based education and skills building, and couple-peer educator support. RESULTS: We recruited 1080 couples to participate in the study. Using a linear mixed effect model with a random effect for clinic, the intervention had no impact on the medication possession ratio among women at 12 months. However, the intervention increased men's medication ratio by 8.77%. Our unadjusted logistic regression model found the odds of an infant seroconverting in the intervention group was 30% less than in the control group, but the results were not statistically significant. DISCUSSION: Our study found no difference in maternal outcomes by study arm, but our intervention resulted in an improved medication possession ratio among male partners. We provide a community/clinic-based treatment framework that can improve outcomes among male partners. Further work needs to be done to improve social support for pregnant women and to facilitate prevention of vertical transmission to infants among couples living with HIV.

BACKGROUND: In 2021, Mozambique initiated community-based oral HIV self-testing (HIVST) to increase testing access and uptake among priority groups, including adult males, adolescents, and young adults. Within an HIVST pilot project, we conducted a performance evaluation assessing participants' ability to successfully conduct HIVST procedures and interpret results. METHODS: A cross-sectional study was performed between February-March 2021 among employees, students (18-24 years of age), and community members, using convenience sampling, in two rural districts of Zambézia Province, Mozambique. We quantified how well untrained users performed procedures for the oral HIVST (Oraquick®) through direct observation using a structured checklist, from which we calculated an HIVST usability index (scores ranging 0-100%). Additionally, participants interpreted three previously processed anonymous HIVST results. False reactive and false non-reactive interpretation results were presented as proportions. Bivariate analysis was conducted using Chi-square and Fisher exact tests. RESULTS: A total of 312 persons participated (131[42%] community members, 71[23%] students, 110[35%] employees); 239 (77%) were male; the mean age was 28 years (standard deviation 10). Average usability index scores were 80% among employees, 86% among students, and 77% among community members. Main procedural errors observed included "incorrect tube positioning" (49%), "incorrect specimen collection" (43%), and "improper waiting time for result interpretation" (42%). From the presented anonymous HIVST results, 75% (n = 234) correctly interpreted all three results, while 9 (3%) of study participants failed to correctly interpret any results. Overall, 36 (12%) gave a false non-reactive result interpretation, 21 (7%) a false reactive result interpretation, and 14 (4%) gave both false non-reactive and false reactive result interpretations. Community members generally had lower performance. CONCLUSIONS: Despite some observed testing procedural errors, most users could successfully perform an HIVST. Educational sessions at strategic places (e.g., schools, workplaces), and support via social media and hotlines, may improve HIVST performance quality, reducing the risk of incorrect interpretation.

The community adherence support group (CASG) was one of the first differentiated service delivery (DSD) models introduced in Mozambique. This study assessed the impact of this model on retention in care, loss to follow-up (LTFU), and viral suppression among antiretroviral therapy (ART)-treated adults in Mozambique. A retrospective cohort study included CASG-eligible adults enrolled between April 2012 and October 2017 at 123 health facilities in Zambézia Province. Propensity score matching (1:1 ratio) was used to allocate CASG members and those who never enrolled in a CASG. Logistic regressions were performed to estimate the impact of CASG membership on 6- and 12-month retention and viral load (VL) suppression. Cox proportional regression was used to model differences in LTFU. Data from 26,858 patients were included. The median age at CASG eligibility was 32 years and 75% were female, with 84% residing in rural areas. A total of 93% and 90% of CASG members were retained in care at 6 and 12 months, respectively, while 77% and 66% non-CASG members were retained during the same periods. The odds of being retained in care at 6 and 12 months were significantly higher among patients receiving ART through CASG support (adjusted odds ratio [aOR] = 4.19 [95% confidence interval; CI: 3.79-4.63], p < .001, and aOR = 4.43 [95% CI: 4.01-4.90], p < .001, respectively). Among 7,674 patients with available VL measurements, the odds of being virally suppressed were higher among CASG members (aOR = 1.14 [95% CI: 1.02-1.28], p < .001). Non-CASG members had a significantly higher likelihood of being LTFU (adjusted hazard ratio = 3.45 [95% CI: 3.20-3.73], p < .001). While Mozambique rapidly scales up multi-month drug dispensation as the preferred DSD model, this study emphasizes the continued importance of CASG as an efficacious DSD alternative, especially among patients residing in rural areas, where CASG acceptability is higher.

BACKGROUND: Postpartum contraceptive uptake reduces short interpregnancy intervals, unintended pregnancies, and their negative sequalae: poor maternal and fetal outcomes. Healthy timing and spacing of pregnancy in people living with HIV (PLHIV) also allows time to achieve viral suppression to reduce parent-to-child HIV transmission. There is scant understanding about how couples-based interventions impact postpartum contraceptive uptake among PLHIV in sub-Saharan Africa. METHODS: We interviewed 38 recently pregnant people and 26 of their partners enrolled in the intervention arm of the Homens para Saúde Mais (HoPS+) [Men for Health Plus] trial to assess their perceptions of, attitudes towards, and experiences with contraceptive use. Individuals in the HoPS+ intervention arm received joint-as opposed to individual-HIV-related services during pregnancy and postpartum periods, six counseling and skills sessions, and nine sessions with a peer support couple. Our thematic analysis of the 64 in-depth interviews generated 14 deductive codes and 3 inductive codes across themes within the Information, Motivation, and Behavior Model of health behavior change. RESULTS: Participants reported accurate and inaccurate information about birth spacing and contraceptive methods. They described personal (health, economic, and religious) and social (gender norms, desired number of children) motivations for deciding whether to use contraceptives-with slightly different motivations among pregnant and non-pregnant partners. Finally, they explained the skills needed to overcome barriers to contraceptive use including how engagement in HoPS+ improved their shared decision-making skills and respect amongst partners-which facilitated postpartum contraceptive uptake. There were also several cases where non-pregnant partners unilaterally made family planning decisions despite disagreement from their partner. CONCLUSIONS: These findings suggest that couples-based interventions during pregnancy and post-partum periods aimed at increasing postpartum contraceptive uptake must center pregnant partners' desires. Specifically, pregnant partners should be allowed to titrate the level of non-pregnant partner involvement in intervention activities to avoid potentially emboldening harmful gender-based intercouple decision-making dynamics.

INTRODUCTION: As COVID-19 continues to spread globally and within Mozambique, its impact among immunosuppressed persons, specifically persons living with HIV (PLHIV), and on the health system is unknown in the country. The 'COVid and hIV' (COVIV) study aims to investigate: (1) the seroprevalence and seroincidence of SARS-CoV-2 among PLHIV and healthcare workers providing HIV services; (2) knowledge, attitudes, practices and perceptions regarding SARS-CoV-2 infection; (3) the pandemic's impact on HIV care continuum outcomes and (4) facility level compliance with national COVID-19 guidelines. METHODS AND ANALYSIS: A multimethod study will be conducted in a maximum of 11 health facilities across Mozambique, comprising four components: (1) a cohort study among PLHIV and healthcare workers providing HIV services to determine the seroprevalence and seroincidence of SARS-CoV-2, (2) a structured survey to assess knowledge, attitudes, perceptions and practices regarding COVID-19 disease, (3) analysis of aggregated patient data to evaluate retention in HIV services among PLHIV, (4) an assessment of facility implementation of infection prevention and control measures. ETHICS AND DISSEMINATION: Ethical approval was obtained from the National Health Bioethics Committee, and institutional review boards of implementing partners. Study findings will be discussed with local and national health authorities and key stakeholders and will be disseminated in clinical and scientific forums. TRIAL REGISTRATION NUMBER: NCT05022407.

BACKGROUND: Historically, antiretroviral therapy (ART) initiation was based on CD4 criteria, but this has been replaced with "Test and Start" wherein all people living with HIV are offered ART. We describe the baseline immunologic status among children relative to evolving ART policies in Mozambique. METHODS: This retrospective evaluation was performed using routinely collected data. Children living with HIV (CL aged 5-14 years) with CD4 data in the period of 2012-2018 were included. ART initiation "policy periods" corresponded to implementation of evolving guidelines: in period 1 (2012-2016), ART was recommended for CD4 <350 cells/mm3; during period 2 (2016-2017), the CD4 threshold increased to <500 cells/mm3; Test and Start was implemented in period 3 (2017-2018). We described temporal trends in the proportion of children with severe immunodeficiency (CD4 <200 cells/mm3) at enrollment and at ART initiation. Multivariable regression models were used to estimate associations with severe immunodeficiency. RESULTS: The cohort included 1815 children with CD4 data at enrollment and 1922 at ART initiation. The proportion of children with severe immunodeficiency decreased over time: 20% at enrollment into care in period 1 vs. 16% in period 3 (P = 0.113) and 21% at ART initiation in period 1 vs. 15% in period 3 (P = 0.004). Children initiating ART in period 3 had lower odds of severe immunodeficiency at ART initiation compared with those in period 1 [adjusted odds ratio (aOR) = 0.67; 95% CI: 0.51 to 0.88]. Older age was associated with severe immunodeficiency at enrollment (aOR = 1.13; 95% CI: 1.06 to 1.20) and at ART initiation (aOR = 1.14; 95% CI: 1.08 to 1.21). CONCLUSIONS: The proportion of children with severe immunodeficiency at ART initiation decreased alongside more inclusive ART initiation guidelines. Earlier treatment of children living with HIV is imperative.

HIV self-testing (HIVST) is a WHO-recommended strategy to increase testing, especially among key populations, men, and young adults. Between May and December 2019, a pilot was implemented in Zambézia province, Mozambique, allowing clients to purchase HIV self-tests in 14 public/private pharmacies. The study assessed the strategy's acceptability and uptake. Pharmacy-based exit surveys were conducted among a random sample of clients, during the first three months of the pilot, independent of HIVST purchase. Another random sample of clients who bought an HIVST completed a survey 1-12 weeks after purchase. Chi-square and Mann-Whitney tests were used for the analysis, comparing clients who purchased an HIVST versus not. A total of 1,139 adults purchased 1,344 tests. Buyers were predominantly male (70%) and younger (52% between 15 and 34 years of age). Surveys were completed by 280 exiting pharmacy clients and 82 clients who purchased an HIVST. Main advantages were confidentiality and lack of need of a health provider visit, with main disadvantages being absence of nearby counseling and fear of results. No differences were seen between buyers and non-buyers for these factors. Among all undergoing HIVST, 71 (92%) perceived the instructions to be clear, however, 29 (38%) stated they would have benefitted from additional pre-test information or counseling. Ten (13%) reported following up at a nearby health facility to confirm results and/or receive care. Offering HIVST at public/private pharmacies was acceptable among people who traditionally tend to have a lower HIV testing coverage, such as men and young adults. However, additional resources and/or enhanced educational materials to address the lack of counseling, and linkage-to-care systems need to be put into place before scaling up this strategy.

INTRODUCTION: Mentor Mothers (MM) provide peer support to pregnant and postpartum women living with HIV (PPWH) and their infants with perinatal HIV exposure (IPE) throughout the cascade of prevention of vertical transmission (PVT) services. MM were implemented in Zambézia Province, Mozambique starting in August 2017. This evaluation aimed to determine the effect of MM on PVT outcomes. METHODS: A retrospective interrupted time series analysis was done using routinely collected aggregate data from 85 public health facilities providing HIV services in nine districts of Zambézia. All PPWH (and their IPE) who initiated antiretroviral therapy (ART) from August 2016 through April 2019 were included. Outcomes included the proportion per month per district of: PPWH retained in care 12 months after ART initiation, PPWH with viral suppression and IPE with HIV DNA PCR test positivity by 9 months of age. The effect of MM on outcomes was assessed using logistic regression. RESULTS: The odds of 12-month retention increased 1.5% per month in the pre-MM period, compared to a monthly increase of 7.6% with-MM (35-61% pre-MM, 56-72% with-MM; p < 0.001). The odds of being virally suppressed decreased by 0.9% per month in the pre-MM period, compared to a monthly increase of 3.9% with-MM (49-85% pre-MM, 59-80% with-MM; p < 0.001). The odds of DNA PCR positivity by 9 months of age decreased 8.9% per month in the pre-MM period, compared to a monthly decrease of 0.4% with-MM (0-14% pre-MM, 4-10% with-MM; p < 0.001). The odds of DNA PCR uptake (the proportion of IPE who received DNA PCR testing) by 9 months of age were significantly higher in the with-MM period compared to the pre-MM period (48-100% pre-MM, 87-100% with-MM; p < 0.001). CONCLUSIONS: MM services were associated with improved retention in PVT services and higher viral suppression rates among PPWH. While there was ongoing but diminishing improvement in DNA PCR positivity rates among IPE following MM implementation, this might be explained by increased uptake of HIV testing among high-risk IPE who were previously not getting tested. Additional efforts are needed to further optimize PVT outcomes, and MM should be one part of a comprehensive strategy to address this critical need.

BACKGROUND: Sub-Saharan Africa reported 550,000 new HIV infections among women in 2018. Pregnancy and the postpartum period are associated with an increased risk of HIV acquisition (adjusted risk ratio [RR]: 2.8 during pregnancy and 4.0 in postpartum period vs. non-pregnant or postpartum women, respectively). Acquisition of HIV during pregnancy and breastfeeding increases risk of mother to child transmission. We propose to test the impact of a peer-delivered oral storytelling intervention to increase retention in, and adherence to, pre-exposure prophylaxis (PrEP)/combination antiretroviral treatment (ART) among expectant couples. DESIGN: We propose a randomized controlled trial (RCT) (35 intervention and 35 control couples) at a health facility where 11% of expectant couples were in serodiscordant relationships in 2018. Couples randomized to the storytelling arm will be visited by a two community volunteers and who successfully adhered to PrEP/ART during a recent pregnancy. This expert couple will orate to participating couples three stories (at 1, 3 and 5 weeks after study enrollment) designed to empower, educate, and establish "ideal" interpersonal communication strategies within couples/families, and support adherence practices among participants. The primary outcome among HIV-uninfected women will be adherence to PrEP at 3 months. CONCLUSIONS: PrEP among at-risk pregnant women must be implemented so that high levels of adherence and retention are achievable for them and their partners. We will test our storytelling intervention to identify an optimal strategy for PrEP education and family engagement in a region with high HIV prevalence. Our results will have an impact by effectively engaging serodiscordant couples in prevention/treatment during pregnancy and beyond.
RESUMEN
BACKGROUND: Pre-exposure prophylaxis (PrEP) has the potential to reduce HIV transmission and stem the HIV epidemic. Unfortunately, PrEP uptake in rural sub-Saharan Africa has been slow and medication adherence has been suboptimal. OBJECTIVE: To explore the perspectives, attitudes, and experiences of HIV serodiscordant partners taking PrEP and develop a messaging campaign to improve PrEP uptake in rural Mozambique to reduce HIV transmission among serodiscordant partners. METHODS: In this qualitative study, we interviewed 20 people in serodiscordant relationships using PrEP at a rural health center in Zambézia province, Mozambique and employed inductive and deductive coding to elicit their perspectives, attitudes, and experiences related to learning their partner's HIV status, barriers to PrEP uptake, obstacles to PrEP adherence, and decisions to disclose their PrEP use with family and friends using thematic analysis. RESULTS: Our analysis generated nine themes across various levels of the socioecological model. Participants reported a strong desire to stay in the discordant relationship and highlighted the importance of working together to ensure PrEP and antiretroviral therapy adherence, with the majority skeptical that adherence could be achieved without both partners' support (individual and interpersonal). Although most participants were reticent about sharing their serodiscordant status with family and friends (individual and interpersonal), those who did found their family and friends supportive (interpersonal). Participants suggested increasing community health agent availability to help people navigate HIV prevention and treatment (organizational). We then created three oral stories, using themes from the interviews, with examples from various levels of the socioecological model that will be used to generate support for PrEP use among community members. CONCLUSIONS: Our findings informed oral template stories that will be used to emphasize how couples can work together to improve PrEP uptake and reduce incident HIV infections in serodiscordant couples elsewhere in rural Mozambique.

INTRODUCTION: Vaccine efficacy testing requires engagement of willing volunteers with high disease incidence. We evaluated factors associated with willingness to participate in potential future HIV vaccine trials in Maputo, Mozambique. METHODS: Adults aged 18-35 years without HIV and who reported at least two sexual partners in the 3 months prior to screening were enrolled into a 24-month observational study. They were asked at screening and exit if they would be willing to participate in a theoretical HIV vaccine study. Bivariate and multivariate logistic regression analyses were done between willingness to participate, demographic, sexual behavior, and motivational factors for screening visit data. Logistic regression with generalized estimating equations (GEE) was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for factors potentially associated with willingness to participate for data from both visits. RESULTS: A total of 577 participants without HIV were eligible, including 275 (48%) women. The mean age was 22.2 (SD ± 3.9) years. At screening 529 (92%) expressed willingness to participate and the proportion remained stable at 378 (88%) of the 430 participants retained through the exit visit (p = 0.209). Helping the country (n = 556) and fear of needles (n = 26) were the top motive and barrier for willingness to participate, respectively. Results from the GEE binary logistic regression (screening visit and exit visit) showed that wanting to learn how to avoid risk behaviors (aOR 3.33, 95% CI: 1.61-6.86) and feeling protected against HIV infection (aOR 2.24, 95% CI: 1.07-4.7) were associated with willingness to participate in HIV vaccine studies. CONCLUSION: The majority of our study population in Mozambique expressed willingness to participate in a theoretical HIV vaccine trial. Participation in a HIV vaccine trial was seen as a way to contribute to the fight against HIV but was associated with some unrealistic expectations such as protection against HIV. This reinforces the need for continuous mobilization and awareness of potential participants to HIV vaccine trial.

BACKGROUND: The ability to understand another's emotions and act appropriately, empathy, is an important mediator of relationship function and health intervention fidelity. We adapted the Interpersonal Reactivity Index (IRI) - an empathy scale - among seroconcordant expectant couples with HIV in the Homens para Saúde Mais (HoPS+) trial - a cluster randomized controlled trial assessing couple-based versus individual treatment on viral suppression - in Zambézia Province, Mozambique. METHODS: Using baseline data from 1332 HoPS+ trial participants (666 couples), an exploratory factor analysis assessed culturally relevant questions from the IRI. Because empathy is interdependent among couples, we validated the results of the exploratory factor analysis using a dyadic confirmatory factor analysis (CFA) with dyadic measurement invariance testing. Finally, we assessed the relationship between scores on our final scale and basic demographic characteristics (sex, age, education, and depression) using t-tests. RESULTS: We found two subscales: 1) a seven-item cognitive empathy subscale (Cronbach's alpha 0.78) and 2) a six-item affective empathy subscale (Cronbach's alpha 0.73). The dyadic CFA found acceptable model fit and metric invariance across partners (Comparative Fit Index (CFI) = 0.914, Tucker Lewis Index = 0.904, Root Mean Squared Error of Approximation = 0.056, ΔCFI = 0.011). We observed higher cognitive (p: 0.012) and affective (p: 0.049) empathy among males and higher cognitive (p: 0.031) and affective (p: 0.030) empathy among younger participants. More educated participants had higher affective empathy (p: 0.017) and depressed participants had higher cognitive empathy (p: < 0.001). This two-subscale, 13-item version of the IRI measures cognitive and affective empathy in HoPS+ trial participants and adults while accounting for the interdependent nature of empathy within partner dyads. CONCLUSIONS: This scale will allow us to assess the interplay between empathy and other psychometric constructs (stigma, social support, etc.) in the HoPS+ trial and how each relates to retention in HIV, adherence to treatment, and prevention of maternal to child HIV transmission. Furthermore, this scale can be adapted for other sub-Saharan African populations, which will allow researchers to better assess HIV-related intervention efficacy. TRIAL REGISTRATION: This study is within the context of the HoPS+ trial, registered at ClinicalTrials.gov as number NCT03149237 . Registered May 11, 2017.
