RESUMO

OBJECTIVE: Estimate the longitudinal associations of state-level anti-LGBTQ+ policies and county-level politics with individual HIV prevention outcomes among sexual and gender minoritized (SGM) youth. DESIGN: Keeping it LITE-1 prospectively enrolled 3,330 SGM youth and young adults (ages 13-34) at increased risk of HIV throughout the United States from 2017-2022. METHODS: Semiannual surveys collected self-reported HIV prevention measures (current PrEP use, weekly PrEP adherence, HIV/STI testing in the past 6 months). Geolocation was linked with state-level LGBTQ+ policy data and county-level election data. Generalized linear models with GEE estimated the single and joint longitudinal associations for 2 exposures [state-level policy climate (more discriminatory vs. less discriminatory) and county-level political majority (Democratic/swing vs. Republican)] with each outcome. RESULTS: Among participants living in a state with more discriminatory laws, those in a Democratic/swing county had a 6-percentage point increase in PrEP use (95% CI: 0.02, 0.09) compared to those in a Republican county. Those living in a Republican county but a state with less discriminatory laws saw a similar increase (0.05; -0.02,0.11). Residing in both a Democratic/swing county and a state with less discriminatory laws, relative to a Republican county and a state with more discriminatory laws, was associated with a 10-percentage point increase in PrEP use (0.10; 0.06,0.14) and a 5-percentage point increase in HIV/STI testing (0.05; 0.00,0.09). CONCLUSIONS: More progressive state and local policies were each associated with increased PrEP use, and together, doubled the magnitude of this association. PrEP is underutilized among SGM youth, and anti-LGBTQ+ policies may exacerbate this gap in coverage.

RESUMO

INTRODUCTION: Cash transfers can reduce adolescent girls and young women's (AGYW) risk of intimate partner violence (IPV). In our own cash transfer intervention (HPTN 068), AGYW who received a cash transfer were less likely to experience IPV than non-recipients, in part because the cash reduced their engagement in sexual partnerships. This mixed-methods study builds on earlier findings to examine whether the protective effects were sustained after the cash ended and when the cash transfer was the most impactful. METHODS: HPTN 068 was an experimental HIV prevention intervention trial. AGYW who participated completed 3 annual surveys during the intervention and an additional survey 2.5 years post-intervention. We used log-binomial regression models to assess the durability of the cash transfer on outcomes and included an interaction term in models to examine when effects were largest. We analyzed qualitative interviews conducted after the cash ended to contextualize findings. RESULTS: Post-intervention, the relative risk of physical IPV was lower among AGYW who received it compared to those who did not, but not statistically significant (RR: 0.83, 95% CI: 0.62, 1.10). AGYW who received the cash transfer also had a lower relative risk of ever having had sex and of having any sexual partner in the last 12 months (RR: 0.94, 95% CI: 0.88, 1.01; RR: 0.94; 95% CI: 0.88, 0.99, respectively). The protective effect of the cash transfer on physical IPV was highest in Years 1 and 2 (RR: 0.64; 95% CI: 0.55-0.75 and RR: 0.65; 95% CI: 0.55-0.77, respectively). Qualitative data corroborated the quantitative findings. CONCLUSION: The cash transfer reduced AGYW's risk of IPV, though effects were attenuated after the cash ended. Provision of cash during adolescence - a period when AGYW are highly susceptible to IPV and HIV - may empower them in their current relationship and yield long term health benefits.

RESUMO

BACKGROUND: One in four South African women will experience intimate partner violence (IPV) in their lifetime, potentially increasing their biological stress. In South Africa, limited IPV and stress research has utilized multiple timepoints or examined modifying factors. Cash transfers (CTs) are associated with reduced IPV and stress and may be an intervention target. AIMS: We used data-driven methods to identify longitudinal IPV trajectory groups among South African adolescent girls and young women (AGYW), estimate each group's association with stress, and assess modification by a CT. METHODS: A total of 2,183 South African AGYW ages 13 to 24 years from the HIV Prevention Trials Network 068 study were randomized to a CT or control group. Physical IPV was measured five times (2011-2017), and stress was captured once (2018-2019). Stress measures included the Cohen Stress Scale and stress biomarkers (C-reactive protein (CRP), cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1)). Group-based trajectory modeling identified IPV trajectories; ordinal logistic regression estimated the association between trajectory group and stress. RESULTS: A two-group quadratic trajectory model was identified (higher trajectory group = 26.7% of AGYW; lower trajectory group = 73.3%). In both groups, the probability of IPV increased from ages 13 to 17 years before declining in early adulthood. However, the higher group's probability peaked later and declined gradually. The higher trajectory group was associated with an increased odds of elevated CRP (OR: 1.41, 95% CI [1.11, 1.80]), but not with other stress measures. The CT modified the relationship with CMV: a positive association was observed among the usual care arm (OR: 1.59, 95% CI [1.11, 2.28]) but not the CT arm (OR: 0.85, 95% CI [0.61, 1.19]). CONCLUSIONS: Sustained IPV risk during adolescence was associated with elevated CRP in young adulthood. The relationship between IPV and elevated CMV was attenuated among those receiving a CT, suggesting that CTs could possibly reduce biological stress due to IPV.

RESUMO

Background: The efficacy of messenger RNA (mRNA)-1273 against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is not well defined, particularly among young adults. Methods: Adults aged 18-29 years with no known history of SARS-CoV-2 infection or prior vaccination for coronavirus disease 2019 (COVID-19) were recruited from 44 US sites from 24 March to 13 September 2021 and randomized 1:1 to immediate vaccination (receipt of 2 doses of mRNA-1273 vaccine at months 0 and 1) or the standard of care (receipt of COVID-19 vaccine). Randomized participants were followed up for SARS-CoV-2 infection measured by nasal swab testing and symptomatic COVID-19 measured by nasal swab testing plus symptom assessment and assessed for the primary efficacy outcome. A vaccine-declined observational group was also recruited from 16 June to 8 November 2021 and followed up for SARS-CoV-2 infection as specified for the randomized participants. Results: The study enrolled 1149 in the randomized arms and 311 in the vaccine-declined group and collected >122 000 nasal swab samples. Based on randomized participants, the efficacy of 2 doses of mRNA-1273 vaccine against SARS-CoV-2 infection was 52.6% (95% confidence interval, -14.1% to 80.3%), with the majority of infections due to the Delta variant. Vaccine efficacy against symptomatic COVID-19 was 71.0% (95% confidence interval, -9.5% to 92.3%). Precision was limited owing to curtailed study enrollment and off-study vaccination censoring. The incidence of SARS-CoV-2 infection in the vaccine-declined group was 1.8 times higher than in the standard-of-care group. Conclusions: mRNA-1273 vaccination reduced the incidence of SARS-CoV-2 infection from March to September 2021, but vaccination was only one factor influencing risk. Clinical Trials Registration: NCT04811664.

RESUMO

BACKGROUND: Adolescent girls and young women (AGYW) living with HIV who have higher stress levels may be at risk of stress-related biological alterations, which could influence HIV progression and adherence to antiretroviral therapy (ART). SETTING: We aimed to estimate associations among stress-responsive biomarkers, ART adherence, and viral suppression in AGYW living with HIV in South Africa. We also hypothesized that psychosocial stressors [eg, depression, food insecurity, low socioeconomic status (SES), and HSV-2] would be associated with higher biomarker levels. METHODS: We used 2018/2019 data from the HIV Prevention Trials Network 068 cohort to assess associations between stress-responsive biomarkers and viral suppression (<1000 copies/mL) and ART adherence measured using dried blood spot cards. Stress-responsive biomarkers included C-reactive protein, herpes simplex virus type 1, and cytomegalovirus infection and reactivation. Associations were estimated using unadjusted log-binomial or ordinal logistic regression models. RESULTS: In 166 AGYW living with HIV, there was no association between stress-responsive biomarkers and viral suppression or ART adherence. However, increased C-reactive protein levels were associated with higher HSV-2 infection [odds ratio (OR) 1.98; 95% confidence interval (CI) 1.11, 3.52], being a government grant recipient (OR 3.21; 95% CI: 1.30, 7.92), lower food insecurity (OR 0.34; 95% CI: 0.13, 0.90), and increased body mass index (OR 1.07; 95% CI: 1.01, 1.14). CONCLUSIONS: High prevalence of psychosocial stressors and persistent herpesviruses in AGYW living with HIV has the potential to lead to poorer health outcomes. More research is needed to untangle relationships between economic stability, chronic disease, and chronic stress.

RESUMO

BACKGROUND: Research trial participation may influence health outcomes regardless of the intervention assigned, but is often not assessed. SETTING: We investigated how participation in an HIV prevention trial (the HIV Prevention Trials Network (HPTN) 068 study) affected health outcomes 4 years after the study in adolescent girls and young women in South Africa beyond effects of the tested intervention. METHODS: We developed an analytical cohort that included the HIV Prevention 068 trial (HPTN 068) trial participants from the Agincourt Health and Demographic Surveillance System and resembled HPTN 068 trial enrollees (aged 13-20 years and in grades 8-11 in 2011) using inverse probability of treatment weights. We estimated risk differences for the association between trial participation and education and early parity (age <20 years) in 2019, after accounting for differences at baseline between the trial participants and nonparticipants. RESULTS: There were 3442 young women enrolled in grades 8-11 in 2011; 1669 were in the HPTN 068 trial. Trial participants were more likely to have completed secondary school by 2019 (adjusted RD (aRD) 5.0%, 95% confidence interval (CI) 2.2%, 7.9%; 82.3% in trial participants vs. 77.2% in nonparticipants). Trial participants had similar risk of parity before age 20 compared with nontrial participants (aRD 2.3%, 95% CI: -0.8%, 5.5%). CONCLUSIONS: Trial participation did not seem to influence early parity, but did increase educational attainment. Our results are compatible with an explanation of Hawthorne effects from trial participation on schooling behaviors that were small, but observable even 4 years after the end of the trial.

RESUMO

Improving men's engagement in HIV prevention is not only essential for reducing their own HIV risk but also the risk of transmitting HIV to their female partners. We conducted a cross-sectional survey using a population-based sample of men (age 18-30) who reported being a partner of an adolescent girls and young women (AGYW) in South Africa (N = 2827). We used logit-binomial regression models to examine associations among men's partnership characteristics, HIV risk perceptions, and HIV-related behaviors and examine differences by male partner age (younger men (18-24) vs. older men (25-30)) and age difference between partners (age-concordant (< 5 years) vs. age-disparate (≥ 5 years)). Most men reported inconsistent condom use (85%) and nearly half reported engaging in transactional sex (48%). Older men were just as likely as younger men, and men with age-disparate and age-concordant partners, to inconsistently use condoms, engage in transactional sex, and perpetrate intimate partner violence. Most men also reported a very high interest in pre-exposure prophylaxis (PrEP) (77%) and half reported having an HIV test in the past year (50%). There were no differences by male partner age or age difference between partners in PrEP interest but older men and men in age-discordant relationships were more likely than younger men and men in age-concordant relationships to have an HIV test in the past year. Male partners of AGYW in South Africa are engaging in HIV-related behaviors and need HIV prevention interventions to reduce risk for themselves and their female partners.

RESUMO

Interactive stories are a relatively newer form of storytelling with great potential to correct misinformation while increasing self-efficacy, which is crucial to vaccine acceptance. To address COVID-19 vaccine hesitancy and medical mistrust in young Black adults (BYA), we sought to adapt a pre-existing application ("app"; Tough Talks) designed to address HIV disclosure decision-making through choose-your-own adventure (CYOA) narratives and other activities. The adapted app (Tough Talks - COVID) uses a similar approach to situate COVID-19 vaccination decision-making within social contexts and to encourage greater deliberation about decisions. To inform content for the CYOA narratives, we conducted an online survey that was used to elicit the behavioral, cognitive, and environmental determinants influencing COVID-19 vaccine hesitancy among 150 BYA (ages 18-29) in Georgia, Alabama, and North Carolina. The survey included scenario questions that were developed with input from a youth advisory board to understand responses to peer and family influences. In two scenarios that involved discussions with family and friends about vaccination status, most respondents chose to be honest about their vaccination status. However, vaccinated individuals perceived more social pressure and stigma about not being vaccinated than unvaccinated respondents who were not as motivated by social pressure. Personal choice/agency in the face of perceived vaccine risks was a more common theme for unvaccinated respondents. Results suggest that relying on changing social norms alone may not impact barriers to vaccination in unvaccinated young adults without also addressing other barriers to vaccination such as concerns about autonomy and vaccine safety. Based on these findings, CYOA narratives in the app were adapted to include discussions with family and friends but also to touch on themes of personal choice as well as other topics that influence behaviors besides norms such as safety, side effects, and risk of COVID-19 in an evolving pandemic.

RESUMO

BACKGROUND: Few studies have focused on attitudes toward COVID-19 vaccination among Black or African American young adults (BYA) in the Southern United States, despite high levels of infection in this population. OBJECTIVE: To understand this gap, we conducted an online survey to explore beliefs and experiences related to COVID-19 vaccination among BYA (aged 18-29 years) in 3 southern states. METHODS: We recruited 150 BYA to participate in an online survey as formative research for an intervention to address vaccine hesitancy in Alabama, Georgia, and North Carolina from September 22, 2021, to November 18, 2021. Participants were recruited through social media ads on Facebook, Twitter, Instagram, and YouTube. Additionally, we distributed information about the survey through organizations working with BYA in Alabama, Georgia, and North Carolina; our community partners; and network collaborations. We used measures that had been used and were previously validated in prior surveys, adapting them to the context of this study. RESULTS: Roughly 28 (19%) of the participants had not received any doses of the COVID-19 vaccine. Half of the unvaccinated respondents (n=14, 50%) reported they wanted to wait longer before getting vaccinated. Motivators to get vaccinated were similar between unvaccinated and vaccinated respondents (eg, if required, to protect the health of others), but the main motivator for those vaccinated was to protect one's own health. Among unvaccinated individuals, reasons for not receiving the COVID-19 vaccine included concern about vaccine side effects (n=15, 54%) and mistrust of vaccine safety (n=13, 46%), of effectiveness (n=12, 43%), and of the government's involvement with vaccines (n=12, 43%). Experiences of discrimination (n=60, 40%) and mistrust of vaccines (n=54, 36%) were common overall. Among all respondents, those who said they would be motivated to get vaccinated if it was required for school, work, or travel were more likely to endorse negative beliefs about vaccines compared to those motivated for other reasons. CONCLUSIONS: Mistrust in COVID-19 vaccine safety and efficacy is common among BYA in the Southern United States, irrespective of vaccination status. Other motivators, such as safety of family and community and vaccination requirements, may be able to tip the scales toward a decision to be vaccinated among those who are initially hesitant. However, it is unclear how vaccine requirements among BYA in the South affect trust in the government or health care in the long term. Interventions that include BYA in vaccination messaging and programs may more proactively build feelings of trust and combat misinformation.

RESUMO

PURPOSE: In South Africa, adolescent mothers have a three times higher risk of HIV acquisition than nonadolescent mothers. Yet, limited evidence exists regarding how early childbearing may affect HIV risk. A better understanding of adolescent mothers' partnership dynamics and sexual behaviors is critical to tailoring interventions to prevent new infections. METHODS: Data are from HIV Prevention Trials Network 068, a longitudinal study of adolescent girls and young women (AGYW) aged 13-20 in South Africa who were followed annually for up to 6 years. Log-binomial regression models were used to assess whether adolescent motherhood was associated with partnership dynamics (intimate partner violence, gender inequitable norms, low relationship power, no HIV prevention communication) and if the association between partnership dynamics and sexual behaviors (unprotected sex and transactional sex) varied by adolescent motherhood. Generalized estimating equations, with an exchangeable correlation structure, were used to account for nonindependence. RESULTS: Adolescent mothers were more likely than nonadolescent mothers to be in partnerships characterized by intimate partner violence, low relationship power, gender inequitable norms, and no HIV prevention communication. A higher proportion were also more likely to experience these dynamics, as well as engage in transactional sex, after giving birth. Poor partnership dynamics put AGYW at a higher risk for unprotected sex and transactional sex, regardless of adolescent motherhood status. DISCUSSION: Engaging adolescent mothers in interventions post birth and developing interventions that address power imbalances in AGYW's sexual partnerships have the potential to reduce engagement in HIV-related sexual behaviors and HIV risk in the long term.

RESUMO

BACKGROUND: Persons with acute HIV infection (AHI) are highly infectious and responsible for a disproportionate share of incident infections. Immediate antiretroviral therapy (ART) rapidly reduces blood viral loads (VLs), but genital VLs after ART initiation during AHI are less well described. SETTING: Lilongwe, Malawi, 2012-2014. METHODS: HIV-seronegative and HIV-serodiscordant persons aged ≥18 years were screened for AHI (RNA positive) and randomized to standard of care, behavioral intervention, or behavioral intervention plus short-term ART (raltegravir/emtricitabine/tenofovir) (1:2:2). Persons who were ART eligible under Malawi guidelines could receive first-line therapy. Blood and genital VLs were assessed at weeks 1, 4, 8, and 12. Fisher's Exact test was used to compare viral suppression by ART status. RESULTS: Overall, 46 persons with AHI were enrolled; of whom, 17 started ART within 12 weeks. Median blood VL at AHI diagnosis was 836,115 copies/mL. At week 12, 7% (1/14) of those who initiated ART had a blood VL of ≥400 copies/mL, compared with 100% (23/23; P < 0.0001) of those who did not initiate ART (median VL: 61,605 copies/mL). Median genital VL at week 1 was 772 copies/mL, with 13 of 22 (59%) having VL of ≥400 copies/mL. At week 12, 0 of 10 (0%) of those who initiated ART had genital VL of ≥400 copies/mL, compared with 7 of 15 (47%) of those who did not initiate ART (P = 0.02). CONCLUSION: Although highly correlated, VLs in blood and genital fluids occupy discrete biological compartments with distinct virologic dynamics. Our results corroborate the dramatic reduction in both compartments after ART initiation. Increasing AHI screening and rapidly initiating treatment is key to interrupting transmission.

RESUMO

BACKGROUND: Adolescent motherhood is common in South Africa and occurs against a backdrop of high HIV risk. While childbearing during adolescence may result in social and economic strain that may negatively impact health, there has been limited study of whether adolescent motherhood increases the risk of HIV or herpes simplex virus type 2 (HSV-2) acquisition or engagement in high-risk sexual partnerships. SETTING: Data are from HIV Prevention Trials Network 068, a longitudinal conditional cash transfer study of adolescent girls and young women (age, 13-23) in rural South Africa. METHODS: We used survival analysis to estimate hazard ratios to determine if adolescent motherhood (live birth before 20 years) predicted incident HIV and incident HSV-2 and generalized estimating equations for behavioral risk ratios to determine if adolescent motherhood was associated with transactional sex and age-disparate partnerships. RESULTS: Of 2452 adolescent girls and young women who were HIV negative at baseline, 5% were adolescent mothers; 16% were adolescent mothers by the end of the study period. After controlling for covariates, adolescent motherhood predicted incident HSV-2 acquisition [ adjusted hazard ratios, 1.30; 95% confidence interval (CI): 1.01 to 1.95] but not HIV acquisition ( adjusted hazard ratios, 1.19; 95% CI, 0.76 to 1.86). Adolescent motherhood was also associated with being in an age-disparate partnership (adjusted risk ratio, 1.30; 95% CI: 1.07 to 1.58) but not transactional sex. CONCLUSION: Adolescent motherhood increased the risk of HSV-2 and engagement in age-disparate partnerships, both known risk factors for HIV infection. Sexually transmitted infection screening and/or tailored combination HIV prevention interventions that account for the context of adolescent motherhood are critical to maximize adolescent mothers' long-term health and to meet UNAIDS 95-95-95 targets by 2030.

RESUMO

Though effective reproductive health interventions have been developed for adolescent girls and young women (AGYW) in sub-Saharan Africa, few have explored whether specific components of the interventions are responsible for observed changes in behaviour. Data for this longitudinal mediation analysis come from a quasi-experimental, sexual and reproductive health study conducted among AGYW (age 15-24) in Malawi. We assessed the extent to which the relationship between attending communication-specific small-group sessions and contraceptive use at one-year was mediated by contraceptive communication with partners at six months, using a bootstrapping procedure to estimate indirect effects. Of 358 participants, 44% attended communication-specific small-group sessions, 37% communicated with partners about contraception at six months, and 21% used non-barrier contraception at one-year. Participants who attended communication-specific small-group sessions had increased contraceptive communication with partners at six months (aOR = 1.48, 95% CI: 1.07-2.38) and increased non-barrier contraceptive use at one-year (aOR = 3.53, 95% CI: 1.86-6.69). The relationship between attending communication-specific small-group sessions and non-barrier contraceptive use at one-year was partially mediated by contraceptive communication with partners at six months (indirect effect = 0.04, 95% CI: 0.01-0.07). Our results suggest that contraceptive communication with partners is modifiable through interventions and important for AGYW non-barrier contraceptive uptake.

RESUMO

The goal of this manuscript is to advance HIV risk behavior prevention efforts for South African adolescent girls by identifying distinct trajectory patterns across multiple behavioral domains for adolescent and young adults. We draw from a sample of N = 1070 adolescent girls from South Africa who were between the ages of 13-15 at baseline. Participants were followed across 6 waves of data collection between 2011 and 2019. We focus on predicting trajectories between ages 15 and 21. All participants were HIV negative and had not experienced sexual debut at baseline. We examine group-based multi-variable trajectories across several known HIV risk behaviors: earlier age of sexual debut, engaging in unprotected sex, engaging in transactional sex, earlier age at first pregnancy, and exposure to physical IPV. We characterized three prototypical joint trajectories: abstainers (54%), early unprotected sex (36%), and high-risk sexually active (11%). We then predicted membership based on the following baseline risk and protective factors: household expenditures, bonding to school, parental monitoring, number of close friends, and community engagement. We found that school bonding and parental monitoring were the strongest predictor of sexual risk, and that, among those in both the early unprotected sex and high-risk groups, risky behaviors like unprotected and transactional sex most frequently occurred early in adolescence. These findings suggest that interventions should target girls early in adolescence, and that interventions focused at improving school bonding and promoting parental involvement may be most effective at preventing risky sexual behavior.

RESUMO

Transactional sex increases HIV risk among adolescent girls and young women (AGYW). Understanding the individual and dyadic nature of transactional sex may provide evidence for risk reduction interventions. Multilevel logistic regression was used to cross-sectionally examine correlates of transactional sex among AGYW in Lilongwe, Malawi. Participants (N = 920) reported 1227 relationships. Individual-level associations were found between being divorced/widowed (AOR 5.07, 95% CI 1.93, 13.25), married (AOR 0.26, 95% CI 0.09, 0.72), or unstably housed (AOR 7.11, 95% CI 2.74, 18.47) and transactional sex. At the relationship-level, transactional sex occurred in relationships with: non-primary primary partners (AOR 4.06, 95% CI 2.37, 6.94), perceived partner concurrency (AOR 1.85, 95% CI 1.11, 3.08), and feared violence with couples HIV testing (AOR 2.81, 95% CI 1.26, 6.29), and less likely to occur in relationships with children (AOR 0.15, 95% CI 0.06, 0.38). Multiple co-occurring social and structural vulnerabilities increase transactional sex engagement warranting the need for social protection and gender transformative approaches.

RESUMO

BACKGROUND: Given the success of cash programs in improving health outcomes and addressing upstream drivers of HIV risk such as poverty and education, there has been an increasing interest in their potential to improve HIV prevention and care outcomes. Recent reviews have documented the impacts of structural interventions on HIV prevention, but evidence about the effects of cash transfer programs on HIV prevention has not been systematically reviewed for several years. METHODS AND FINDINGS: We did a systematic review of published and unpublished literature to update and summarize the evidence around cash programs for HIV prevention from January 2000 to December 17, 2020. We included studies with either a cash transfer intervention, savings program, or program to reduce school costs. Included studies measured the program's impact on HIV infection, other sexually transmitted infections (STIs), or sexual behaviors. We screened 1,565 studies and examined 78 in full-text review to identify a total of 45 peer-reviewed publications and reports from 27 different interventions or populations. We did not do a meta-analysis given the range of outcomes and types of cash transfer interventions assessed. Most studies were conducted in sub-Saharan Africa (N = 23; South Africa, Tanzania, Malawi, Lesotho, Kenya, Uganda, Zimbabwe, Zambia, and eSwatini) followed by Mexico (N = 2), the United States (N = 1), and Mongolia (N = 1)). Of the 27 studies, 20 (72%) were randomized trials, 5 (20%) were observational studies, 1 (4%) was a case-control study, and 1 (4%) was quasi-experimental. Most studies did not identify a strong association between the program and sexual behaviors, except sexual debut (10/18 finding an association; 56%). Eight of the 27 studies included HIV biomarkers, but only 3 found a large reduction in HIV incidence or prevalence, and the rest found no statistically significant association. Of the studies that identified a statistically significant association with other STIs (N = 4/8), 2 involved incentives for staying free of the STI, and the other 2 were cash transfer programs for adolescent girls that had conditionalities related to secondary schooling. Study limitations include the small number of studies in key populations and examining interventions to reduce school costs and matched saving programs. CONCLUSIONS: The evidence base for large-scale impacts of cash transfers reducing HIV risk is limited; however, government social protection cash transfer programs and programs that incentivize school attendance among adolescent girls and young women show the greatest promise for HIV prevention.

RESUMO

BACKGROUND: Depression is highly prevalent among people living with HIV in Malawi. Depression can undermine engagement in HIV care and worsen HIV morbidity and mortality. The Ministry of Health integrated a pilot depression management program into HIV care at 2 clinics. This program included a measurement-based care protocol for prescribing antidepressants and an adapted Friendship Bench psychotherapy protocol for providing problem solving. Early evaluations indicated successful integration of the initial stages of training and depression screening, diagnosis, and treatment initiation. This follow-up mixed-method investigation contextualizes our previous findings and shares insights from the implementation experience. METHODS: We conducted a mixed-methods process evaluation drawing on both patient clinical data and qualitative interviews with patients and clinic staff. We focus on the following implementation outcomes: fidelity, acceptability, and sustainability. RESULTS: Although fidelity to depression screening and treatment initiation was high, fidelity to the follow-up treatment protocol was poor. Antidepressants and problem-solving therapy were acceptable to patients, but clinic staff found delivering treatment challenging given constrained human resources and infrastructure. The program was not sustained after the project. Key identified needs included substantial support to supervise the implementation of the program, continue to build and maintain the capacity of providers, integrate the program into the electronic medical records system, and ensure the availability of Friendship Bench counselors. CONCLUSIONS: Although initial steps were successful, sustained integration of this depression treatment program into HIV care in this setting met greater challenges. Implementation science studies that support both implementation and evaluation should recognize the potential for clinical implementers to rely on evaluation staff for clinical support and consider distancing evaluation staff from the actual program implementation. Further research is needed to test enhanced implementation strategies for integrating evidence-based mental health interventions into existing health care systems in a sustainable fashion, particularly in low-resource settings.

RESUMO

In sub-Saharan Africa, adolescent girls and young women (AGYW) have high levels of unmet need for contraception, particularly those who are unmarried or nulliparous. Conversations with partners, peers, and family members influence AGYW contraceptive decision-making yet little is known about conversation content and impact or how they vary by relationship status and parity. This paper draws on qualitative data from 60 AGYW (aged 15-24) participating in a sexual and reproductive health study in Malawi to examine contraceptive conversation patterns among participants and their social ties. AGYW's relationship status and parity influenced whether they talked about contraceptives, who they talked to about contraceptives, and the type of contraceptives that were endorsed during conversations. Unmarried and nulliparous AGYW were less likely to discuss contraceptives with all social ties and when conversations occurred, norms and misinformation regarding nonbarrier methods were reinforced, and condoms were largely prescribed. Conversations with intimate partners often provided permission for contraceptive use while conversations with peers and older women in the family provided information on contraceptive methods. Our results highlight the unique roles that social ties play in AGYW contraceptive decision-making and suggest that existing contraceptive conversation patterns might exclude unmarried, nulliparous AGYW from accurate and comprehensive contraceptive information and options.

RESUMO

INTRODUCTION: Malawi's malaria burden is primarily assessed via cross-sectional national household surveys. However, malaria is spatially and temporally heterogenous and no analyses have been performed at a subdistrict level throughout the course of a year. The WHO recommends mass distribution of long-lasting insecticide-treated bed nets (LLINs) every 3 years, but a national longitudinal evaluation has never been conducted in Malawi to determine LLIN effectiveness lifespans. METHODS: Using District Health Information Software 2 (DHIS2) health facility data, available from January 2018 to June 2020, we assessed malaria risk before and after a mass distribution campaign, stratifying by age group and comparing risk differences (RDs) by LLIN type or annual application of indoor residual spraying (IRS). RESULTS: 711 health facilities contributed 20 962 facility reports over 30 months. After national distribution of 10.7 million LLINs and IRS in limited settings, malaria risk decreased from 25.6 to 16.7 cases per 100 people from 2018 to 2019 high transmission seasons, and rebounded to 23.2 in 2020, resulting in significant RDs of -8.9 in 2019 and -2.4 in 2020 as compared with 2018. Piperonyl butoxide (PBO)-treated LLINs were more effective than pyrethroid-treated LLINs, with adjusted RDs of -2.3 (95% CI -2.7 to -1.9) and -1.5 (95% CI -2.0 to -1.0) comparing 2019 and 2020 high transmission seasons to 2018. Use of IRS sustained protection with adjusted RDs of -1.4 (95% CI -2.0 to -0.9) and -2.8% (95% CI -3.5 to -2.2) relative to pyrethroid-treated LLINs. Overall, 12 of 28 districts (42.9%) experienced increases in malaria risk in from 2018 to 2020. CONCLUSION: LLINs in Malawi have a limited effectiveness lifespan and IRS and PBO-treated LLINs perform better than pyrethroid-treated LLINs, perhaps due to net repurposing and insecticide-resistance. DHIS2 provides a compelling framework in which to examine localised malaria trends and evaluate ongoing interventions.

RESUMO

In Malawi, 50% of adolescent girls and young women (AGYW) have had a first child by age 19 and 45% report their pregnancies as unintended or mistimed. Yet, uptake of contraception remains low. Understanding how interactions with social ties impact AGYW contraceptive use might explain low uptake beyond individual and environmental factors. Data are from Girl-Power, a study among sexually active AGYW, aged 15-24, in Malawi. We used logistic regression models to examine whether contraceptive communication and social norms (descriptive and injunctive) were associated with contraceptive use (non-barrier methods and condoms) and how associations differed across social ties (older women in the family, peers, and partners). The sample included 942 participants: 28% reported using non-barrier methods and 66% reported using condoms. Contraceptive communication with older women in the family (aOR: 1.48, 95% CI: 0.99, 2.20), peers (aOR: 3.12, 95% CI: 1.96, 4.96), and partners (aOR 5.15, 95% CI: 3.13, 8.48) was associated with non-barrier method use. Descriptive norms were associated with non-barrier methods among peers (aOR 2.57, 95% CI: 1.63, 4.96) but not among older women in the family (aOR: 1.22, 95% CI 0.80, 1.88). There were no associations among contraceptive communication, social norms, and condom use across older women in the family, peers, and partners. The findings highlight the need to consider the influence of social ties in the design of future family planning interventions and suggest that interventions that encourage interpersonal communication about contraception and target peer-based descriptive norms have the potential to impact uptake of non-barrier methods.
