RESUMEN

BACKGROUND: A substantial proportion of persons on antiretroviral therapy (ART) considered lost to follow-up have actually transferred their human immunodeficiency virus (HIV) care to other facilities. However, the relationship between facility switching and virologic outcomes, including viral rebound, is poorly understood. METHODS: We used data from 40 communities (2015-2020) in the Rakai Community Cohort Study to estimate incidence of facility switching and viral rebound. Persons aged 15-49 years with serologically confirmed HIV who self-reported ART use and contributed ≥1 follow-up visit were included. Facility switching and virologic outcomes were assessed between 2 consecutive study visits (ie, index and follow-up visits, interval of approximately 18 months). Those who reported different HIV treatment facilities between index and follow-up study visits were classified as having switched facilities. Virologic outcomes included viral rebound among individuals initially suppressed (<200 copies/mL). Multivariable Poisson regression was used to estimate associations between facility switching and viral rebound. RESULTS: Overall, 2257 persons who self-reported ART use (median age, 35 years; 65% female, 92% initially suppressed) contributed 3335 visit-pairs and 5959 person-years to the analysis. Facility switching was common (4.8 per 100 person-years; 95% confidence interval [CI], 4.2-5.5) and most pronounced in persons aged <30 years and fishing community residents. Among persons suppressed at their index visit (n = 2076), incidence of viral rebound was more than twice as high in persons who switched facilities (adjusted incidence rate ratio = 2.27; 95% CI, 1.16-4.45). CONCLUSIONS: Facility switching was common and associated with viral rebound among persons initially suppressed. Investments in more agile, person-centered models for mobile clients are needed to address system inefficiencies and bottlenecks that can disrupt HIV care continuity.

RESUMEN

Women's ability to control their fertility and have the number of children they want when they want them is an internationally recognized human right. This right has been the driving force behind family planning programs in low- and middle-income countries for more than five decades. The HIV epidemic added greater urgency to those efforts once the risk of vertical transmission of the virus from mothers to their infants was recognized. In 2013, we published a systematic review of the evidence of effectiveness of family planning counseling for women living with HIV, emphasizing HIV related behaviors. In this updated review, we examined 23 studies, primarily from sub-Saharan Africa. The evidence we uncovered reflected efforts to integrate services provided to women. These showed that providing contraceptive services, including intensified counseling and support, in the HIV clinics where women living with HIV received their care increased the likelihood of subsequent use of modern contraception by as much as fourfold. These studies reflected a greater focus on women's family planning decisions and behaviors and less focus on HIV-related behaviors. Among the possible causes of this noted difference we include the widespread coverage of antiretroviral treatment for HIV. This advance has apparently changed the rationale and the approach to integrating family planning and HIV services in ways that may not have been fully appreciated. The results, however, are beneficial: greater coverage of family planning for women who wish to control their fertility and a more equal partnership between family planning services and HIV services in pursuit of the mutual goal of providing integrated services to meet women's needs.

RESUMEN

Motivational Interviewing (MI) and Community Health Workers (CHWs) are increasingly utilized in global settings to improve HIV outcomes, yet research exploring implementation strategies using MI and CHWs is lacking. We examined the experiences of CHWs and their clients in a counseling intervention which used MI-informed counseling to increase engagement in HIV prevention and treatment. This study was nested within the mLAKE cluster-randomized trial in a high HIV prevalence fishing community in rural Rakai District, Uganda. We conducted in-depth interviews with purposively-sampled CHWs (n = 8) and clients (n = 51). Transcripts were analyzed thematically to characterize CHWs' implementation of the intervention. Main themes identified included use of specific MI strategies (including evocation, guidance towards positive behavior change, active listening, and open-ended questions), and MI spirit (including collaboration, power-sharing, trust, and non-judgmental relationship building). Through these specific MI mechanisms, CHWs supported client behavior change to facilitate engagement with HIV services. This study provides evidence from a low-resource setting that CHWs with no previous experience in MI can successfully implement MI-informed counseling that is well-received by clients. CHW-led MI-informed counseling appears to be a feasible and effective approach to increase uptake of HIV prevention and care services in low-resource, HIV endemic regions.

RESUMEN

We conducted a systematic review and meta-analysis of the impact of needle and syringe exchange programs (NSP) on both individual- and community-level needle-sharing behaviors and other HIV-related outcomes in low- and middle-income countries (LMIC). A search of five databases for peer-reviewed trial or quasi-experimental studies reported through July 2021 identified 42 interventions delivered in 35 studies, with a total of 56,751 participants meeting inclusion criteria. Random-effects meta-analysis showed a significant protective association between NSP exposure and needle-sharing behaviors at the individual-level (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.16-0.39, 8 trials, n = 3947) and community-level (OR 0.39, CI 0.22-0.69, 12 trials, n = 6850), although with significant heterogeneity. When stratified by needle-sharing directionality, NSP exposure remained associated with reduced receptive sharing, but not distributive sharing. NSP exposure was also associated with reduced HIV incidence and increased HIV testing but there were no consistent associations with prevalence of bloodborne infections. Current evidence suggests positive impacts of NSPs in LMICs.


RESUMEN: Realizamos una revisión sistemática y un metanálisis del impacto de los programas de intercambio de agujas y jeringas (NSP, por sus siglas en inglés) de los comportamientos de uso compartido de agujas tanto a nivel individual como comunitario y otros resultados relacionados con el VIH en países de ingresos bajos y medianos (LMIC, por sus siglas en inglés). Realizamos búsquedas sistemáticas en cinco bases de datos hasta julio de 2021 en busca de ensayos revisados por pares o estudios cuasiexperimentales. En general, 42 intervenciones informadas en 35 estudios entre 56 751 participantes cumplieron los criterios de inclusión. El metanálisis de efectos aleatorios de ocho estudios a nivel individual y 12 a nivel comunitario con 11 075 participantes en total mostró una asociación protectora significativa entre la exposición a NSP y los comportamientos de compartir agujas (individual: OR 0,25, IC95%: 0,16­0,39; comunidad: OR 0,39, IC95%:0,22­0,69), aunque con una heterogeneidad importante. Cuando se estratificó por la direccionalidad del intercambio de agujas, la exposición a NSP permaneció asociada con un intercambio receptivo reducido, pero no con un intercambio distributivo. La exposición a NSP también se asoció con una incidencia reducida del VIH y un aumento de las pruebas del VIH, pero no hubo asociaciones consistentes para la prevalencia de infecciones transmitidas por la sangre. La evidencia actual sugiere impactos positivos de los NSP en los LMIC.

RESUMEN

Mental health problems (e.g., anxiety, depression) are frequently experienced by adolescents living with HIV (ALWH) and can worsen HIV-related outcomes. This scoping review synthesizes the existing research on ALWHs' mental health problems at multiple steps along the HIV care continuum in sub-Saharan Africa. Searching PubMed, CINAHL, EMBASE, and PsycINFO identified 34 peer-reviewed studies that met inclusion criteria. Most studies assessed ALWHs' mental health problems at the "Engaged or Retained in Care" continuum step, are cross-sectional, focus on depression and anxiety, and used measures developed in high-income countries. Studies identify mental health problems among ALWH as prevalent and barriers to care. Significant gaps remain in understanding how mental health problems and their relationships with HIV-related health outcomes shift across the continuum. Additional attention is needed, especially at the HIV testing and viral suppression steps, to generate a more comprehensive understanding of mental health needs and priority timepoints for intervention for ALWH.

RESUMEN

The COVID-19 pandemic and subsequent mitigation measures led to social disruption and negative economic shocks for a large proportion of Uganda's population. The social and economic consequences of COVID-19 on Ugandan men's sexual behaviours, including transactional sex relationships, are unclear. We conducted in-depth interviews between November 2021-February 2022 with 26 men in a high HIV prevalence region of Uganda. Data were analysed thematically to understand how sexual relationships, including transactional sex, were impacted by COVID-19. We found that COVID-19 mitigation measures had far-reaching social and economic impacts on most respondents, particularly those employed in the informal economy. Men described experiencing job loss, food insecurity and restricted mobility, which limited opportunities to provide for and meet with transactional sex partners. Inability to provide financial resources meant that men could not form new transactional sex relationships and men who could no longer provide for their existing transactional sex partners consistently reported relationship dissolution. Men who reported stable employment during the pandemic described few changes in transactional sex relationships. Similarly, men in non-transactional relationships did not report relationship dissolution despite decreased financial provision. Further research should assess the potential short- and long-term impacts of COVID-19 mitigation measures on transactional sex relationships.

RESUMEN

BACKGROUND: Faith-based organizations (FBOs) have a scant history in the literature of implementing intimate partner violence (IPV) initiatives, though many members of faith communities consider it an important issue. Furthermore, the limited studies on this topic have not explored organizational factors that are important in the implementation of such efforts. PURPOSE: To investigate factors that influence the implementation of IPV prevention and response by one Catholic organization at both diocesan and parish levels. METHODS: We conducted sixteen semi-structured interviews with members of Archdiocese of Chicago Domestic Violence Outreach (ACDVO) leadership. Using deductive content analysis, we drew on all 14 constructs and sub-constructs from the inner setting domain of the Consolidated Framework for Implementation Research (CFIR) for coding transcripts and characterizing factors influencing implementation success. RESULTS: Seven CFIR constructs were useful in identifying factors that influenced implementation success of ACDVO. At the diocesan level, the organization's leadership structure, their driven culture, and in-kind available resources propelled their work. At the level of parish ministries, successful implementation was facilitated by networking and communication among parishes. At the diocesan-level, access to knowledge and information through ACDVO's Parish Support Committee, compatibility with parish values, leadership engagement, and available resources from parishes supported implementation. CONCLUSIONS: We identified modifiable and reproducible inner setting factors that influence implementation of a Catholic IPV initiative at the diocesan-level and support parish ministries in their local activities. Future work should validate these findings in other dioceses and examine non-Catholic FBO settings.

RESUMEN

Background. Across settings, individuals from populations that are multiply stigmatized are at increased risk of HIV and experience worse HIV treatment outcomes. As evidence expands on how intersecting stigmatized identities and conditions influence HIV outcomes, researchers have used diverse quantitative approaches to measure HIV-related intersectional stigma and discrimination. To date, no clear consensus exists regarding how to best quantitatively measure and analyze intersectional stigma and discrimination. Objectives. To review and document existing quantitative measures of HIV-related intersectional stigma and discrimination to inform research, programmatic, and policy efforts. Search Methods. We searched 5 electronic databases for relevant studies. References of included articles were screened for possible inclusion. Additional articles were screened on the basis of consultations with experts in the field. Selection Criteria. We included peer-reviewed studies published between January 1, 2010, and May 12, 2021, that were HIV related and presented 1 or more quantitative measures of stigma and discrimination using an intersectional lens in measure design or analysis. Data Collection and Analysis. Systematic methods were used to screen citations and abstract data via a standardized coding form. Data were analyzed by coding categories stratified according to 2 subgroups: (1) studies incorporating a single intersectional measure and (2) studies that examined intersectional stigma through analytical approaches combining multiple measures. Main Results. Sixteen articles met the inclusion criteria, 7 of which explicitly referenced intersectionality. Ten studies were from the United States. All of the studies included participants living with HIV. Among the 4 studies incorporating a single intersectional stigma measure, 3 explored race and gender stigma and 1 explored gender and HIV stigma. Studies involving analytic approaches (n = 12) mostly examined intersectional stigma via interaction terms in multivariate regression models. Three studies employed structural equation modeling to examine interactive effects or latent constructs of intersectional stigma. Conclusions. Research on the measurement of HIV-related intersectional stigma and discrimination is currently concentrated in high-income settings and generally focuses on the intersection of 2 identities (e.g., race and gender). Efforts are needed to expand appropriate application of intersectionality in the development, adaptation, and use of measures of HIV-related intersectional stigma and discrimination. The use of context-, identity-, or condition-adaptable measures should be considered. Researchers should also carefully consider how to meaningfully engage communities in the process of measurement development. Public Health Implications. The measures and analytic approaches presented could significantly enhance public health efforts in assessing the impact of HIV-related intersectional stigma and discrimination on critical health outcomes.

RESUMEN

A community health worker (CHW) model can promote HIV prevention and treatment behaviors, especially in highly mobile populations. In a fishing community in Rakai, Uganda, the Rakai Health Sciences Program implemented a CHW HIV intervention called Health Scouts. The situated Information, Motivation, and Behavioral Skills (sIMB) framework informed the design and a qualitative evaluation of the intervention. We interviewed 51 intervention clients and coded transcripts informed by sIMB framework dimensions. Clients reported that Health Scouts provided information about HIV prevention and treatment behaviors and helped them manage personal and social motivations to carry out health-promoting behavior. Prominent barriers which moved clients away from behavior change included daily pill burdens, anticipated stigma, serostatus disclosure, substance use at social gatherings, and anticipated reactions of partners. Our study adds to the evidence establishing CHWs as facilitators of behavior change, positioned to offer supportive encouragement and navigate contextualized circumstances.

RESUMEN

If sexual partner concurrency drives HIV transmission dynamics, shouldn't HIV prevention efforts be addressing this behavior? We systematically reviewed studies evaluating interventions to reduce sexual partner concurrency in low- and middle-income countries using pre/post or multi-arm designs. Only two studies met our inclusion criteria; neither found significant differences by intervention exposure on self-reported concurrency. Overall, very few interventions have specifically targeted concurrency, and those that did have not been rigorously evaluated. In practice, concurrency may be difficult to separate from multiple partnerships more generally.

RESUMEN

BACKGROUND: Non-communicable diseases such as cardiovascular conditions and diabetes are rising in sub-Saharan Africa. Prevention strategies to mitigate non-communicable diseases include improving diet, physical activity, early diagnosis, and long-term management. Early identification of individuals at risk based on risk-score models - such as the Framingham Risk Score (FRS) for 10-year risk of cardiovascular disease and the Finnish type 2 Diabetes risk score (FINDRISC) for type 2 diabetes which are used in high-income settings - have not been well assessed in sub-Saharan Africa. The purpose of this study was to qualitatively assess local knowledge of components of these risk scores in a rural Ugandan setting. METHODS: Semi-structured qualitative in-depth interviews were conducted with a purposively selected sample of 15 participants who had responded to the FRS and FINDRISC questionnaires and procedures embedded in the Rakai Community Cohort Study. Data were summarized and categorized using content analysis, with support of Atlas.ti. RESULTS: Participants described local terms for hypertension ("pulessa") and type 2 diabetes ("sukaali"). Most participants understood physical activity as leisure physical activity, but when probed would also include physical activity linked to routine farm work. Vegetables were typically described as "plants", "leafy greens", and "side dish". Vegetable and fruit consumption was described as varying seasonally, with peak availability in December after the rainy season. Participants perceived themselves to have good knowledge about their family members' history of type 2 diabetes and hypertension. CONCLUSIONS: While most items of the FRS and FINDRISC were generally well understood, physical activity needs further clarification. It is important to consider the seasonality of fruits and vegetables, especially in rural resource-poor settings. Current risk scores will need to be locally adapted to estimate the 10-year risk of cardiovascular diseases and type 2 diabetes in this setting.

RESUMEN

BACKGROUND: Effective implementation strategies are needed to increase engagement in HIV services in hyperendemic settings. We conducted a pragmatic cluster-randomized trial in a high-risk, highly mobile fishing community (HIV prevalence: approximately 38%) in Rakai, Uganda, to assess the impact of a community health worker-delivered, theory-based (situated Information, Motivation, and Behavior Skills), motivational interviewing-informed, and mobile phone application-supported counseling strategy called "Health Scouts" to promote engagement in HIV treatment and prevention services. METHODS AND FINDINGS: The study community was divided into 40 contiguous, randomly allocated clusters (20 intervention clusters, n = 1,054 participants at baseline; 20 control clusters, n = 1,094 participants at baseline). From September 2015 to December 2018, the Health Scouts were deployed in intervention clusters. Community-wide, cross-sectional surveys of consenting 15 to 49-year-old residents were conducted at approximately 15 months (mid-study) and at approximately 39 months (end-study) assessing the primary programmatic outcomes of self-reported linkage to HIV care, antiretroviral therapy (ART) use, and male circumcision, and the primary biologic outcome of HIV viral suppression (<400 copies/mL). Secondary outcomes included HIV testing coverage, HIV incidence, and consistent condom use. The primary intent-to-treat analysis used log-linear binomial regression with generalized estimating equation to estimate prevalence risk ratios (PRR) in the intervention versus control arm. A total of 2,533 (45% female, mean age: 31 years) and 1,903 (46% female; mean age 32 years) residents completed the mid-study and end-study surveys, respectively. At mid-study, there were no differences in outcomes between arms. At end-study, self-reported receipt of the Health Scouts intervention was 38% in the intervention arm and 23% in the control arm, suggesting moderate intervention uptake in the intervention arm and substantial contamination in the control arm. At end-study, intention-to-treat analysis found higher HIV care coverage (PRR: 1.06, 95% CI: 1.01 to 1.10, p = 0.011) and ART coverage (PRR: 1.05, 95% CI: 1.01 to 1.10, p = 0.028) among HIV-positive participants in the intervention compared with the control arm. Male circumcision coverage among all men (PRR: 1.05, 95% CI: 0.96 to 1.14, p = 0.31) and HIV viral suppression among HIV-positive participants (PRR: 1.04, 95% CI: 0.98 to 1.12, p = 0.20) were higher in the intervention arm, but differences were not statistically significant. No differences were seen in secondary outcomes. Study limitations include reliance on self-report for programmatic outcomes and substantial contamination which may have diluted estimates of effect. CONCLUSIONS: A novel community health worker intervention improved HIV care and ART coverage in an HIV hyperendemic setting but did not clearly improve male circumcision coverage or HIV viral suppression. This community-based, implementation strategy may be a useful component in some settings for HIV epidemic control. TRIAL REGISTRATION: ClinicalTrials.gov NCT02556957.

RESUMEN

OBJECTIVE: How clinics structure the delivery of antiretroviral therapy (ART) services may influence patient adherence. We assessed the relationship between models of HIV care delivery and adherence as measured by medication possession ratio (MPR) among treatment-experienced adults in Tanzania, Uganda and Zambia. METHODS: Eighteen clinics were grouped into three models of HIV care. Model 1-Traditional and Model 2-Mixed represented task-sharing of clinical services between physicians and clinical officers, distinguished by whether nurses played a role in clinical care; in Model 3-Task-Shifted, clinical officers and nurses shared clinical responsibilities without physicians. We assessed MPR among 3,419 patients and calculated clinic-level MPR summaries. We then calculated the mean differences of percentages and adjusted residual ratio (aRR) of the association between models of care and incomplete adherence, defined as a MPR <90%, adjusting for individual-level characteristics. RESULTS: In the adjusted analysis, patients in Model 1-Traditional were more likely than patients in Model 2-Mixed to have MPR <90% (aRR = 1.60, 95% CI 1-2.48). Patients in Model 1-Traditional were no more likely than patients in Model 3-Task-Shifted to have a MPR <90% (aRR = 1.58, 95% 0.88-2.85). There was no evidence of differences in MPR <90% between Model 2-Mixed and Model 3-Task-Shifted (aRR = 0.99, 95% CI 0.59-1.66). CONCLUSION: Non-physician-led ART programmes were associated with adherence levels as good as or better than physician-led ART programmes. Additional research is needed to optimise models of care to support patients on lifelong treatment.

RESUMEN

Transactional sex (TS) is prevalent in sub-Saharan Africa. Women's engagement in TS is linked with HIV infection; little is known about the relationship between TS, intimate partner violence (IPV) and alcohol use-established HIV risk behaviors. Using modified Poisson regression, we assessed associations between TS and physical, verbal and sexual IPV among 8248 women (15-49 years) who participated in the Rakai Community Cohort Study across forty communities in Uganda. An interaction term assessed moderation between alcohol use and TS and no significant interaction effects were found. In adjusted analysis, alcohol use and TS were significantly associated with all forms of IPV. In stratified analysis, TS was only associated with IPV in agrarian communities; alcohol use was not associated with physical IPV in trade communities or sexual IPV in trade and fishing communities. Identifying differences in IPV risk factors by community type is critical for the development of tailored interventions.


RESUMEN: El sexo transaccional (ST) es frecuente en África subsahariana. La participación de las mujeres en el ST está relacionada con la infección por VIH; Se sabe poco sobre la relación entre el ST, la violencia de pareja íntima (VPI) y el consumo de alcohol: conductas de riesgo establecidas para el VIH. Utilizando la regresión de Poisson modificada, evaluamos las asociaciones entre el ST y la VPI física, verbal y sexual entre 8,248 mujeres (15-49 años) que participaron en el Estudio de cohorte de la comunidad Rakai en cuarenta comunidades de Uganda. Un término de interacción evaluó la moderación entre el consumo de alcohol y el ST y no se encontraron efectos de interacción significativos. En el análisis ajustado, el consumo de alcohol y el ST se asociaron significativamente con todas las formas de VPI. En el análisis estratificado, el ST solo se asoció con la VPI en las comunidades agrarias; El consumo de alcohol no se asoció con la VPI física en las comunidades comerciales ni con la VPI sexual en las comunidades comerciales y pesqueras. Identificar las diferencias en los factores de riesgo de la violencia de género por tipo de comunidad es fundamental para el desarrollo de intervenciones personalizadas.

RESUMEN

We examined the relationship between past-year violence victimization and viral load (VL) failure among consecutively-sampled male and female adolescents and young adults, aged 15-24, in four HIV clinics in Ndola, Zambia. Measures of past-year physical violence, psychological abuse, and forced sex were adapted from the ICAST-C and WHO Multi-Country Study. Using logistic regression, we derived associations between VL failure (≥ 1000 copies/mL) and: any victimization; cumulative victimization; and types and perpetrators of violence. Among 272 youth (59.2% female, 72.8% perinatally infected), 73.5% (n = 200) experienced past-year violence and 36.8% (n = 100) had VL failure. Higher odds of VL failure were observed for participants who reported high frequency of any violence versus no violence victimization (adjusted OR, aOR: 3.58; 95% CI 1.14-11.27), high frequency of psychological abuse versus no psychological abuse (aOR: 3.32; 95% CI 1.26-8.70), any versus no violence from a family member other than a parent/caregiver for physical violence (aOR: 2.18, 95% CI 1.05-4.54) and psychological abuse (aOR: 2.50; 95% CI 1.37-4.54), and any versus no physical violence from a friend/peer (aOR: 2.14, 95% CI 1.05-4.36). Past-year violence victimization was associated with VL failure when considering the frequency, type, and perpetrator of violence. Programs addressing violence among youth living with HIV may be critical to improving viral suppression and preventing onward transmission.

RESUMEN

Uganda piloted HIV pre-exposure prophylaxis (PrEP) for priority populations (sex workers, fishermen, truck drivers, discordant couples) in 2017. To assess facilitators and barriers to PrEP uptake and adherence, we explored perceptions of PrEP before and experiences after rollout among community members and providers in south-central Uganda. We conducted 75 in-depth interviews and 12 focus group discussions. We analyzed transcripts using a team-based thematic framework approach. Partners, family, peers, and experienced PrEP users provided adherence support. Occupational factors hindered adherence for sex workers and fishermen, particularly related to mobility. Pre-rollout concerns about unskilled/untrained volunteers distributing PrEP and price-gouging were mitigated. After rollout, awareness of high community HIV risk and trust in PrEP effectiveness facilitated uptake. PrEP stigma and unexpected migration persisted as barriers. Community-initiated, tailored communication with successful PrEP users may optimize future engagement by addressing fears and rumors, while flexible delivery and refill models may facilitate PrEP continuation and adherence.


RESUMEN: En 2017, Uganda introdujo profilaxis pre-exposición (PrEP), dirigida a las populaciones con alto riesgo de contraer al VIH (trabajadoras sexuales, pescadores, camioneros, parejas sero-discordantes). Para investigar facilitadores y barreras para la adopción y la adherencia a la PrEP, exploramos percepciones de PrEP antes y después de su introducción en Uganda. Realizamos 75 entrevistas y 12 grupos focales con miembros de la comunidad y trabajadores de salud. Analizamos las transcripciones temáticamente usando un marco de referencia. Parejas, familias, compañeros, y clientes usando PrEP apoyaron a los demás mantener adherencia. Movilidad fue una barrera para la adherencia a la PrEP para trabajadoras sexuales y pescadores. Preocupaciones sobre el entrenamiento de los distribuidores de PrEP y la especulación de precios no fueron realizadas. Percepciones del riesgo del VIH y confianza en la eficacia de PrEP facilitaron su adopción. Estigma y migración inesperada persistieron como barreras para la adopción de PrEP. Comunicaciones manejadas por clientes usando PrEP pueden motivar interés en PrEP y abordar rumores. Sistemas flexibles del entrego y la recarga de medicinas pueden permitir continuación de, y adherencia a, la PrEP.

RESUMEN

Communication between sexual partners is an important component of HIV prevention and occurs within a broader context of socio-culturally defined gender norms and dynamics. We analyzed cross-sectional data from a community-based random sample of men and women living in Kisarawe, Tanzania to understand factors related to partner communication about HIV. Bivariate and multivariate logistic regression analyses, disaggregated by gender, included variables at the individual-, relational-, and community-levels. Individuals who knew their HIV-positive status prior to the study were excluded as the focus was on risk communication, not HIV status disclosure. Of 524 participants, 129 women (43.3%) and 96 men (42.5%) reported HIV-related communication with their most recent sexual partner. For women but not men, individual-level socioeconomic factors-including education, possession of a household radio, and employment-and relational-level factors-including partner age and type-were significantly associated with partner communication. At the community level, being socially engaged was positively correlated with partner communication across genders (aOR = 2.02, 95% CI 1.05-3.89, p = 0.03 for men and aOR = 1.74, 95% CI 1.03-2.95, p = 0.04 for women). For women, having less discriminatory attitudes toward people living with HIV and favorable perceived norms of HIV-related communication were significantly associated with partner communication. For men, agreeing that women should be allowed to work outside the home was significantly correlated with partner communication (aOR = 6.02, 95% CI 2.23-16.24, p < 0.001). Findings suggest a link between gender dynamics and partner communication, with individual and relational factors being associated with communication for women and community-level factors being associated with communication for both genders.

RESUMEN

Uganda adopted voluntary medical male circumcision (VMMC) in 2010, but uptake remains disproportionately low in the Northern region despite implementing several demand creation strategies. This study explored the socio-cultural and structural enhancers and barriers to uptake of VMMC services in Gulu, a district in Northern Uganda where uptake is lowest. In September 2016, we conducted 19 focus group discussions, 9 in-depth interviews, and 11 key informant interviews with 149 total participants. Data were collected and analyzed thematically using both inductive and deductive approaches, then framed in four levels of the social ecological model. Enhancers included adequate knowledge about VMMC services, being young and single, partner involvement, peer influence, perceived increased libido after circumcision, and availability of free and high-quality VMMC services. Barriers included sexual abstinence during wound healing, penile appearance after circumcision, religion, culture, and misconceptions. Optimizing enhancers and addressing barriers could increase VMMC service uptake in northern Uganda.

RESUMEN

Antiretroviral treatment (ART) diversion from prescribed to non-prescribed users (i.e., sharing or selling) is an understudied dimension of HIV treatment adherence. We sought to explore ART diversion patterns in high-prevalence fishing communities on Lake Victoria, Uganda. We implemented a qualitative study in two fishing communities on Lake Victoria in south-central Uganda to identify facilitators of and pathways to ART diversion. We conducted 25 semi-structured interviews with HIV-positive fishermen (n = 25) and female sex workers (n = 10) covering personal and community experiences with ART selling/sharing, reasons for medication diversion, and potential solutions to reduce diversion. Data were analyzed using an adapted framework analysis approach. Participants reported frequent ART sharing within occupational networks, but no selling. Mobility was the principal driver of ART sharing and was associated with other barriers to treatment access including stigma, fear of negative health provider interactions, and transportation. ART sharing appears to emerge in response to short-term treatment interruptions in this setting. Future studies should explore characteristics and drivers of ART diversion in other high-burden settings and identify how these practices are correlated with key health outcomes like virologic failure and drug resistance.

RESUMEN

Reproductive coercion (RC), or partner interference in reproductive decisions, limits women's autonomy. Little is known about RC behaviors and measurement in low- and middle-income countries (LMICs). In this mixed-methods study, we examined the transferability of the US-developed RC Scale to the Kenyan context. Through community-based sampling, recent intimate partner violence (IPV) survivors were recruited from Nairobi's informal settlements. We conducted quantitative analyses (n = 327) to assess the transferability of RC measures via exploratory factor analysis and used descriptive statistics to examine prevalence and continuous metrics. We conducted in-depth interviews (IDIs; n = 30) to contextualize results. Psychometric analyses indicated a two-factor solution comprising pregnancy coercion and condom manipulation (alpha = 0.86). Eighty-two percent of IPV survivors reported experiencing RC (pregnancy coercion = 76.6 percent; condom manipulation = 59.5 percent). IDIs highlighted women's multiple, severe RC experiences; experiences described in IDIs were largely consistent with quantitative findings. We found the RC Scale was transferable to this LMIC context, where IPV survivors face prevalent, severe RC and would benefit from linkage to woman-centered support services.
