RESUMEN

This paper explores the definition of, and perceived community attitudes, toward kudanga, a Swahili street term for a type of transactional sex practised in Dar es Salaam, Tanzania. Rooted in economic and gender disparity, transactional sex increases adolescent girls' and young women's vulnerability to HIV and gender-based violence. We sought to understand perceived community attitudes about kudanga, and how the internalisation of norms surrounding gender-based violence relate to the experiences of young women who practise kudanga. Using qualitative data from focus group discussions with 37 young women, we found that community perceptions of kudanga were largely negative, and those who engaged in it were looked down upon and despised. Violence and lack of sexual agency were normalised when doing kudanga. However, young women understood kudanga to often be their best option to obtain economic stability and felt strongly that those who practised kudanga should not be stigmatised. Our research provides further evidence that transactional sex exists on a continuum and highlights the importance of reducing community stigma surrounding transactional sex as a means of decreasing risk of HIV and gender-based violence for young women. To our knowledge, this article is the first to explore kudanga.

RESUMEN

Out-of-school adolescent girls/young women (AGYW) in Africa are at increased risk for HIV and are underserved by HIV prevention interventions. Identifying social networks of out-of-school AGYW may be a strategic approach for reaching them. A sequential mixed methods study design was used. The PLACE (Priorities for Local AIDS Control Efforts) methodology, implemented in one ward of Dar es Salaam, Tanzania, identified 69 networks of AGYW. We randomly selected 28 networks and conducted surveys and network assessments with 80.9% (n = 310) of the members. On average, the networks consisted of 13.7 members, and had a density of 0.65 and a transitivity of 0.80, indicating high cohesion. The networks were mostly female (92%). On average, 67% of network membership were AGYW aged 15-24 years, of whom 70% were out-of-school and 67% were sexually active. Among sexually active AGYW aged 15-24, self-reported HIV seropositivity was 12.2%. We then conducted focus group discussions with 6 purposively selected networks. AGYW described their networks as sources of support and advice. Social norms supported AGYW engaging in transactional sex to alleviate life's hardships; it was the easiest way to earn income without "sweating". AGYW discussed IPV as a common experience, and social norms stigmatized AGYWs' use of condoms. AGYW were largely unaware of pre-exposure prophylaxis. The self-reported HIV prevalence rates of this cohort were higher than national averages, suggesting we tapped into high-risk networks. Social norms promoted transactional and unprotected sex. Social networks are an acceptable channel for HIV prevention intervention delivery to out-of-school AGYW.

RESUMEN

ABSTRACT: Among 145 individuals surveyed in Tanzania, 42% indicated willingness to test for human immunodeficiency virus in response to a confidential, phone-based text message. On average, participants were likely to provide contact information for 1.5 members of their social networks, suggesting high feasibility and moderate acceptability of a novel mHealth human immunodeficiency virus testing intervention.

RESUMEN

CONTEXT: This article aims to highlight challenges and adaptations made by local health officials in Tanzania in working to contain and manage COVID-19. METHODS: The study takes an inductive approach, drawing on the reported experiences of 40 officials at different levels of government across four purposefully selected regions in July 2020. Interviewees were asked about the guidance they received to contain COVID-19, the source of that guidance, their challenges and successes in implementing the guidance, and if and how they adapted the guidance to their particular setting. FINDINGS: The interviews depict considerable challenges, including a lack of supplies and resources for implementing infection control, surveillance, and mitigation practices and dealing with fear and stigma. At the same time, they also provide evidence of innovation and adaptation among street-level bureaucrats. Respondents overwhelmingly praised the president, whose limited national response is seen as helpful for reducing fear and stigma. CONCLUSIONS: Other scholars have highlighted the potential dangers of street-level discretion if local officials "make policy" in ways that contradict their agencies' stated goals. In contrast, our study suggests benefits of autonomy at the street level-particularly in contexts where the central state was relatively weak and/or acting against the public interest.

RESUMEN

Undocumented Latinx immigrants experience unique factors prior to migration, during migration, and after migration that shape their health. Our review summarizes the limited but growing literature highlighting how exposure to trauma, immigration enforcement, changes to social networks, and discrimination negatively affect the mental and physical health of undocumented Latinx immigrants. We also discuss how policies and social ties can promote their health. We focus on areas of particular concern, including health care, mental health, and HIV. Future research should use interdisciplinary approaches and intersectional frameworks to understand and address health inequities. Conducting research with undocumented Latinx immigrant communities requires community engagement, assurance of confidentiality, and creative recruitment and retention strategies. Recommendations for public health practice include investing in community health centers and organizations to ensure access to health and social services; presenting results with sufficient contextualization to interpret their generalizability; and advocating for federal-, state-, and local-level policy changes that reduce the negative health consequences associated with being undocumented.

RESUMEN

Latinx immigrants have poorer access to health care, compared to non-Latinx Whites. Federally-Qualified Health Centers (FQHCs) provide clinical and community programing to address their clients' health needs. One mechanism by which FQHC's may strengthen Latinx immigrant well-being is by promoting their individual and community resilience. We partnered with La Clínica del Pueblo (La Clínica), an FQHC serving Latinx immigrants in Washington, DC and Prince George's County, Maryland. We conducted in-depth interviews in Spanish with 30 La Clínica clients to explore the daily adversities they faced, how they coped, and how La Clínica helped them cope. We conducted thematic analysis using Dedoose software. All participants were from Central America; 37% were undocumented. Participants were 18-78 years old, 70% cis-females, 23% cis-males (10% gay men), and 7% transgender. 57% reported a serious health issue, including diabetes. Participants identified three main adversities: immigration legal status, language, and isolation/depression. Residents of Prince George's, compared to DC, as well as sexual/gender minorities, reported more barriers to accessing health care. Sources of individual resilience for participants included fighting to improve their children's lives, relying on supportive networks, and using La Clínica as a safety net to overcome health access barriers. Sources of community resilience included La Clínica's safe spaces, support groups, referrals to outside legal service providers, and health promoter training. Latinx immigrants face multiple daily adversities, but we find evidence that La Clínica's community health action approach promotes their resilience. We offer a conceptual model for how FQHCs can foster resilience and strengthen immigrant health.

RESUMEN

Black and Latina transgender women (BLTW) are disproportionately impacted by HIV but remain underrepresented in HIV and health services research. Between March 2016 and May 2017, BLTW (N = 201) were recruited in Baltimore, Maryland and Washington, DC through convenience sampling for a survey assessing multilevel determinants of HIV risk and treatment outcomes. Interviews concluded with a rapid oral HIV test. Bivariate and multivariable logistic regression modeling was performed to identify gender affirmation-related correlates of self-reported HIV treatment interruptions (HIVTIs) among BLTW living with HIV who had initiated antiretroviral therapy (ART) (n = 96). Among them, 57.3% (n = 55) reported at least one HIVTI. Unmet surgical needs (aOR = 1.6), past-year marijuana use (aOR = 14.6), and no current hormone use (aOR = 24.9) were significantly (p < 0.05) associated with HIVTIs in multivariable analysis. Unmet need for gender affirmation may inhibit ART adherence, highlighting opportunities to mitigate care interruptions in alignment with community needs and goals.

RESUMEN

The effectiveness of peer leaders in promoting health may depend on the position they occupy within their social networks. Using sociocentric (whole network) and behavioral data from the intervention arm of a cluster-randomized HIV prevention trial in Dar es Salaam, Tanzania, we used generalized linear models with standardized predictors to examine the association between heath leaders' baseline structural network position (i.e., in-degree and betweenness centrality) and their 12-month self-reported (1) confidence in educating network members about HIV and gender-based violence (GBV) and (2) number of past-week conversations about HIV and GBV. As in-degree centrality increased, leaders reported fewer HIV-related conversations. As betweenness centrality increased, leaders reported greater number of conversations about GBV. Network position was not significantly associated with confidence in discussing either topic. Our results suggest that peer leaders who occupy spaces between sub-groups of network members may be more effective in engaging their peers in sensitive or controversial topics like GBV than more popular peer leaders.

RESUMEN

Men in sub-Saharan Africa have low HIV testing rates. Social networks exert an important influence on men's HIV-related behavior. We examined associations between network factors and HIV testing among men in Dar es Salaam, Tanzania. Data are from the baseline assessment of an HIV prevention trial with 48 primarily male networks. Among 923 sexually active men, 52 % had ever tested for HIV. In a random effects logistic regression model, men in the network core were 1.50 times more likely (p < .05) to test than those in the periphery. Percentage of women in the network was associated with men's increased HIV testing (AOR 4.24, p < .05). Perception of network HIV stigma was negatively associated with HIV testing (AOR 0.92, p < .01). Thinking at least one close friend tested for HIV was associated with increased testing (AOR 2.66, p < .001). Social network interventions are a promising approach for scaling up men's HIV testing.

RESUMEN

Social network influence on young people's sexual behavior is understudied in sub-Saharan Africa. Previous research identified networks of mostly young men in Dar es Salaam who socialize in "camps". This study describes network characteristics within camps and their relationship to young men's concurrent sexual partnerships. We conducted surveys with a nearly complete census of ten camp networks (490 men and 160 women). Surveys included name generators to identify camp-based networks. Fifty seven percent of sexually active men (n = 471) reported past year concurrency, measured using the UNAIDS method. In a multivariable model, men's individual concurrency was associated with being a member of a closer knit camp in which concurrency was the normative behavior. Younger men who had older members in their networks were more likely to engage in concurrency. Respondent concurrency was also associated with inequitable personal gender norms. Our findings suggest strategies for leveraging social networks for HIV prevention among young men.

RESUMEN

Men have lower rates of HIV testing and higher rates of AIDS-related mortality compared to women in sub-Saharan Africa. To assess whether there is an opportunity to increase men's uptake of testing by correcting misperceptions about testing norms, we compare men's perceptions of their closest friend's HIV testing behaviors with the friend's actual testing self-report using a unique dataset of men sampled within their social networks (n = 59) in Dar es Salaam, Tanzania. We examine the accuracy and bias of perceptions among men who have tested for HIV (n = 391) and compare them to the perceptions among men who never tested (n = 432). We found that testers and non-testers did not differ in the accuracy of their perceptions, though non-testers were strongly biased towards assuming that their closest friends had not tested. Our results lend support to social norms approaches designed to correct the biased misperceptions of non-testers to promote men's HIV testing.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) and sexually transmitted infections (STIs), including HIV, remain important public health problems with devastating health effects for men and women in sub-Saharan Africa. There have been calls to engage men in prevention efforts, however, we lack effective approaches to reach and engage them. Social network approaches have demonstrated effective and sustained outcomes on changing risk behaviors in the U.S. Our team has identified and engaged naturally occurring social networks comprised mostly of young men in Dar es Salaam in an intervention designed to jointly reduce STI incidence and the perpetration of IPV. These stable networks are locally referred to as "camps." In a pilot study we demonstrated the feasibility and acceptability of a combined microfinance and peer health leadership intervention within these camp-based peer networks. METHODS DESIGN: We are implementing a cluster-randomized trial to evaluate the efficacy of an intervention combining microfinance with health leadership training in 60 camps in Dar es Salaam, Tanzania. Half of the camps have been randomized to the intervention arm, and half to a control arm. The camps in the intervention arm will receive a combined microfinance and health leadership intervention for a period of two years. The camps in the control arm will receive a delayed intervention. We have enrolled 1,258 men across the 60 study camps. Behavioral surveys will be conducted at baseline, 12-months post intervention launch and 30-month post intervention launch and biological samples will be drawn to test for Neisseria gonorrhea (NG), Chlamydia trachomatis (CT), and Trichomonas vaginalis (TV) at baseline and 30-months. The primary endpoints for assessing intervention impact are IPV perpetration and STI incidence. DISCUSSION: This is the first cluster-randomized trial targeting social networks of men in sub-Saharan Africa that jointly addresses HIV and IPV perpetration and has both biological and behavioral endpoints. Effective approaches to engage men in HIV and IPV prevention are needed in low resource, high prevalence settings like Tanzania. If we determine that this approach is effective, we will examine how to adapt and scale up this approach to other urban, sub-Saharan African settings.

RESUMEN

This study analyzed electronic health record (EHR) data from 2016 through 2019 from a federally qualified health center (FQHC) serving predominantly low-income Latine immigrants in the Washington, D.C. metropolitan area to examine how changes in health insurance coverage relate to changes in health care use. Federally qualified health center clients were insured for an average of 59% to 63% of their annual visits, but about one-third had no coverage throughout the year. Findings from descriptive regression and within-client fixed effects models indicate that in years with higher proportions of insured visits, clients averaged more medical visits and interpreter services but fewer mental health and care coordination visits. Latine immigrant clients in D.C., a city with a universal health insurance option, had health insurance coverage for 89% of their visits, and averaged more medical and fewer coordination visits relative to those in a neighboring county in a state without a universal insurance option.

RESUMEN

Latino immigrants living in the United States were highly vulnerable to the health and economic consequences brought on by the COVID-19 pandemic. We use the conceptual framing of workplace dignity, worth that is acknowledged based on performance of job responsibilities, to explore Latino immigrants' experiences during the early months of the pandemic. A qualitative study was conducted with La Clínica del Pueblo (La Clínica), a community health center serving low-income Latino immigrants. From June to December 2020, we conducted in-depth video interviews with 29 Latino immigrant clients to explore pandemic-related challenges, including workplace changes, discriminatory experiences, and effects on health. We conducted thematic analysis using Dedoose software. Nearly half of participants were undocumented immigrants. Most participants were unemployed or underemployed due to the pandemic and 26-49 years of age; one-third were still working, and one-quarter were 50 years or older. About half were cisgender women and two were transgender women. Employed participants experienced a lack of dignity through being socially isolated and stigmatized at work; receiving no compensation for their extra labor or for sick leave; and experiencing discriminatory labor practices. Unemployed participants experienced a lack of dignity in being the first to lose their jobs without government support; losing self-esteem; and not being rehired. Participants associated denial of dignity with worsening health conditions and increased anxiety and depression. Our study suggests that denial of workplace dignity-through job loss, underemployment, and poor working conditions-is linked to adverse health outcomes for Latino immigrants. More research should recognize workplace dignity as an important social determinant of health.

RESUMEN

BACKGROUND: Critical to efforts to end the HIV epidemic is the identification of persons living with HIV who have yet to be diagnosed and engaged in care. Expanded HIV testing outreach efforts need to be both efficient and ambitious, targeting the social networks of persons living with HIV and those at above-average risk of undiagnosed HIV infection. The ubiquity of mobile phones across many high HIV prevalence settings has created opportunities to leverage mobile health (mHealth) technologies to engage social networks for HIV testing outreach, prevention, and treatment. OBJECTIVE: The purpose of this study is to evaluate the acceptability and efficacy of a novel mHealth intervention, "Confidential Social Network Referrals for HIV Testing (CONSORT)," to nudge at-risk individuals to test for HIV using SMS text messages. METHODS: We will conduct the CONSORT study in Moshi, Tanzania, the commercial center and administrative capital of the Kilimanjaro Region in northern Tanzania. After qualitative formative work and pilot testing, we will enroll 400 clients presenting for HIV counseling and testing and 200 persons living with HIV and receiving care at HIV care and treatment centers as "inviters" into a randomized controlled trial. Eligible participants will be aged 18 years or older and live, work, or regularly receive care in Moshi. We will randomize inviters into 1 of 2 study arms. All inviters will be asked to complete a survey of their HIV testing and risk behaviors and to think of social network contacts who would benefit from HIV testing. They will then be asked to whom they would prefer to extend an HIV testing invitation in the form of a physical invitation card. Arm 1 participants will also be given the opportunity to extend CONSORT invitations in the form of automated confidential SMS text messages to any of their social network contacts or "invitees." Arm 2 participants will be offered physical invitation cards alone. The primary outcome will be counselor-documented uptake of HIV testing by invitees within 30 days of inviter enrollment. Secondary outcomes will include the acceptability of CONSORT among inviters, the number of new HIV diagnoses, and the HIV risk of invitees who present for testing. RESULTS: Enrollment in the randomized controlled trial is expected to start in September 2024. The findings will be disseminated to stakeholders and published in peer-reviewed journals. CONCLUSIONS: If CONSORT is acceptable and effective for increasing the uptake of HIV testing, given the minimal costs of SMS text reminders and the potential for exponential but targeted growth using chain referrals, it may shift current practices for HIV testing programs in the area.

RESUMEN

Understanding the uptake and patterns of sexual partnerships of adolescent males reveals their risky behaviors that could persist into adulthood. Using venue-based sampling, we surveyed 671 male youth ages 15-19 from an urban Tanzanian neighborhood about their sexual partnerships during the past 6 months. The proportion of males who had ever had sex increased with age (21 % at age 15; 70 % at age 17; 94 % at age 19), as did the proportion who engaged in concurrency (5 % at age 15; 28 % at age 17; 44 % at age 19). Attendance at ≥2 social venues per day and meeting a sexual partner at a venue was associated with concurrency. Concurrency was associated with alcohol consumption before sex among 18-19 year olds and with not being in school among 15-17 year olds. We find that concurrency becomes normative over male adolescence. Venue-based sampling may reach youth vulnerable to developing risky sexual partnership patterns.

RESUMEN

Respondent-driven sampling (RDS) is a method for recruiting "hidden" populations through a network-based, chain and peer referral process. RDS recruits hidden populations more effectively than other sampling methods and promises to generate unbiased estimates of their characteristics. RDS's faithful representation of hidden populations relies on the validity of core assumptions regarding the unobserved referral process. With empirical recruitment data from an RDS study of female sex workers (FSWs) in Shanghai, we assess the RDS assumption that participants recruit nonpreferentially from among their network alters. We also present a bootstrap method for constructing the confidence intervals around RDS estimates. This approach uniquely incorporates real-world features of the population under study (e.g., the sample's observed branching structure). We then extend this approach to approximate the distribution of RDS estimates under various peer recruitment scenarios consistent with the data as a means to quantify the impact of recruitment bias and of rejection bias on the RDS estimates. We find that the hierarchical social organization of FSWs leads to recruitment biases by constraining RDS recruitment across social classes and introducing bias in the RDS estimates.

RESUMEN

OBJECTIVES: Mass COVID-19 vaccination in Africa is required to end the pandemic. In low-income settings, street-level bureaucrats (SLBs), or public officials who interact directly with citizens, are typically responsible for carrying out vaccination plans and earning community confidence in vaccines. The study interviewed SLBs to assess their perceptions of the factors affecting COVID-19 vaccination rollout in Tanzania. METHODS: We interviewed 50 SLBs (19 rural; 31 urban) responsible for implementing COVID-19 vaccination microplans across four diverse regions and districts of Tanzania in September 2021. Moreover, we conducted six in-depth interviews with non-governmental organisation representatives and seven focus group discussions with health facility governing committees. We asked for their perceptions of factors facilitating and challenging vaccine rollout according to three preidentified domains: political, health system and community. We analysed translated transcripts using a thematic analysis approach. RESULTS: Political factors facilitating mass vaccination included the executive leadership change from a denialist president to a president who accepted vaccines and promoted transparency. Global integration, commercially and politically, also motivated vaccine acceptance. Political challenges included community confusion that emerged from the consecutive presidents' divergent communications and messaging by prominent religious antivaccination leaders. Health system factors facilitating vaccination included scaling up of immunisation sites and campaigns. Urban district officials reported greater access to vaccination sites, compared with rural officials. Limited financial resources for paying healthcare workers and for transport fuel and a lack of COVID-19 testing compromised mass vaccination. Furthermore, SLBs reported being inadequately trained on COVID-19 vaccine benefits and side effects. Having community sources of accurate information was critical to mass vaccination. Challenges at the community level included patriarchal gender dynamics, low risk perception, disinformation that the vaccine has satanic elements, and lack of trust in coronavirus vaccines. CONCLUSION: Mass COVID-19 vaccination in Tanzania will require greater resources and investment in training SLBs to mitigate mistrust, overcome misinformation, and engage communities.

RESUMEN

Aim: Process evaluations for social and behavioral interventions are increasingly important as interventions become more complex and multi-faceted. Conducting process evaluations in low-resource international settings can be challenging. Process evaluations in low-resource international settings can help inform and improve quality of ongoing intervention implementation. We conducted a process evaluation of a cluster-randomized controlled trial to assess the efficacy of a microfinance and health leadership program on sexually transmitted infections and intimate partner violence perpetration among young men in Tanzania. Subject and Methods: Our trial included 1,491 participants and the intervention lasted two years. We collected process data on microfinance loan uptake and repayment, and health leaders' health conversations with peers to monitor intervention reach and dose received. We developed a database system that allowed offline data collection and synced to a central database when internet was accessible. Research staff in the U.S. accessed data from the central database to analyze and create regular implementation reports. Results: Process graphical reports facilitated identification of implementation challenges and enabled us to resolve issues before they worsened. For example, from a group with low microfinance loan repayment we learned area participants perceived the loan to be a grant, and then we clarified the misinformation with participants. Conclusions: The process evaluation helped inform ongoing intervention implementation, including approaches to improve reach and uptake of interventions. Field staff time was protected by systemizing the sharing of data processing and analyses across the global team.
