RESUMO

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.

RESUMO

Heavy alcohol use (HAU) can destabilize engagement along the HIV care continuum. Population-based studies assessing associations of HAU with HIV treatment outcomes are lacking, especially in sub-Saharan Africa. We leveraged data from the Kenya Population-based HIV Impact Assessment to identify associations of self-reported HAU, assessed using two items measuring the frequency and quantity of past-year alcohol consumption, with serum biomarkers for HIV serostatus unawareness, antiretroviral therapy (ART) non-use, and HIV viremia (≥1000 RNA copies/mL). Overall and sex-stratified survey-weighted logistic regression with jackknife variance estimation modeled adjusted odds ratios (adjOR) of HIV treatment indicators by HAU. Overall, 1491 persons living with HIV aged 15-64 years (68.4% female) were included. The prevalence of HAU was 8.9% (95% confidence interval [95%CI]: 6.8-11.0%) and was significantly more pronounced in males than females (19.6% vs. 4.0%, p < 0.001). In multivariable analysis, HAU was significantly (p < 0.001) associated with HIV serostatus unawareness (adjOR = 3.65, 95%CI: 2.14-6.23), ART non-use (adjOR = 3.81, 95%CI: 2.25-6.43), and HIV viremia (adjOR = 3.13, 95%CI: 1.85-5.32). Incorporating sex-specific alcohol use screening into HIV testing and treatment services in populations where HAU is prevalent could optimize clinical outcomes along the HIV care continuum.

RESUMO

Relative to neighboring countries, Zambia has among the most progressive abortion policies, but numerous sociopolitical constraints inhibit knowledge of pregnancy termination rights and access to safe abortion services. Multistage cluster sampling was used to randomly select 1,486 women aged 15-44 years from households in three provinces. We used latent class analysis (LCA) to partition women into discrete groups based on patterns of endorsed support for legalized abortion on six socioeconomic and health conditions. Predictors of probabilistic membership in latent profiles of support for legal abortion services were identified through mixture modeling. A three-class solution of support patterns for legal abortion services emerged from LCA: (1) legal abortion opponents (∼58 percent) opposed legal abortion across scenarios; (2) legal abortion advocates (∼23 percent) universally endorsed legal protections for abortion care; and (3) conditional supporters of legal abortion (∼19 percent) only supported legal abortion in circumstances where the pregnancy threatened the fetus or mother. Advocates and Conditional supporters reported higher exposure to family planning messages compared to opponents. Relative to opponents, advocates were more educated, and Conditional supporters were wealthier. Findings reveal that attitudes towards abortion in Zambia are not monolithic, but women with access to financial/social assets exhibited more receptive attitudes towards legal abortion.

RESUMO

After nearly a decade of HIV pre-exposure prophylaxis (PrEP) rollout in sub-Saharan Africa, there has been limited study of PrEP messaging in news media. We selected twenty South African newspapers with the highest circulation volumes to retrieve articles published in 2012-2021 mentioning PrEP (N = 249). Using inductive content analysis, we developed a structured codebook to characterise PrEP-related content and sentiments, as well as their evolution over time, in the South African press. Many articles espoused favourable attitudes towards PrEP (52%), but a sizeable fraction espoused unfavourable attitudes (11%). Relative to PrEP-favourable articles, PrEP-unfavourable articles were significantly more likely to emphasise the drawbacks/consequences of PrEP use, including adherence/persistence requirements (52% vs. 24%, p = .007), cost (48% vs. 11%, p < .001), and risk compensation (52% vs. 5%, p < .001). Nevertheless, the presence of these drawbacks/consequences in print media largely declined over time. Key populations (e.g. adolescents, female sex workers) were frequently mentioned potential PrEP candidates. Despite message variations over time, prevention effectiveness and adherence/persistence requirements were the most widely cited PrEP benefits and drawbacks, respectively. Study findings demonstrate the dynamic nature of PrEP coverage in the South African press, likely in response to PrEP scale-up and real-world PrEP implementation during the study period.

RESUMO

BACKGROUND: Overdose prevention centers (OPCs), also known as supervised injection facilities and safe consumption sites, are evidenced-based interventions for preventing overdose deaths and drug-related morbidities. The pathways to legalizing OPCs in the USA have confronted multiple social, political, and legal obstacles. We conducted a multi-site, qualitative study to explore heterogeneities in these pathways in four jurisdictions, as well as to understand stakeholder perspectives on valuable strategies for galvanizing political and public support for OPCs. METHODS: From July 2022 to February 2023, we conducted 17 semi-structured, in-depth interviews with OPC policymakers, service providers, advocates, and researchers from California, New York City, Philadelphia, and Rhode Island, where efforts have been undertaken to authorize OPCs. Using inductive thematic analysis, we identified and compared contextually relevant, salient approaches for increasing support for OPCs. RESULTS: Participants described several strategies clustering around five distinct domains: (1) embedding OPC advocacy into broader overdose prevention coalitions to shape policy dialogs; (2) building rapport with a plurality of powerbrokers (e.g., lawmakers, health departments, law enforcement) who could amplify the impact of OPC advocacy; (3) emphasizing specific benefits of OPCs to different audiences in different contexts; (4) leveraging relationships with frontline workers (e.g., emergency medicine and substance use treatment providers) to challenge OPC opposition, including 'NIMBY-ism,' and misinformation; and (5) prioritizing transparency in OPC decision-making to foster public trust. CONCLUSION: While tailored to the specific socio-political context of each locality, multiple OPC advocacy strategies have been deployed to cultivate support for OPCs in the USA. Advocacy strategies that are multi-pronged, leverage partnerships with stakeholders at multiple levels, and tailor communications to different audiences and settings could yield the greatest impact in increasing support for, and diffusing opposition to, future OPC implementation.

RESUMO

Policy and research on the implementation of services for people who inhale drugs lag behind similar efforts for people who inject drugs, limiting access to adequate harm reduction resources for people who inhale drugs. This commentary considers why supervised inhalation sites (SIS) are needed, highlights operational characteristics of four existing services, and advocates for future SIS research. Our hope is to encourage the expansion of SIS worldwide for overdose prevention and reduction of health inequities. Given the limited literature regarding SIS, more extensive study of these programs is warranted to incorporate inhalation into the implementation of supervised consumption sites to provide fair opportunities for all people who use drugs to do so safely without fear of stigma and overdose.

RESUMO

Pre-exposure prophylaxis (PrEP) is a promising but underutilized HIV prevention tool among people who inject drugs (PWID). We developed and piloted an intervention to bolster PrEP promotion competencies among frontline harm reduction workers (FHRW) serving PWID clients in Baltimore, Maryland. Between December 2021 and February 2022, we developed and facilitated four trainings, which included didactic and practice-based/role-playing components, with 37 FHRW from four organizations. FHRW completed three structured surveys (pretest, posttest, 6-week posttest) and in-depth interviews (n = 14) to measure changes in PrEP promotion competencies attributable to training participation. PrEP knowledge and self-efficacy increased significantly (p < 0.001) from pretest to posttest, sustained through 6-week posttest. The proportion of FHRW discussing PrEP with clients doubled during the evaluation period (30-67%, p = 0.006). Feeling empowered to discuss PrEP and provision of population-tailored PrEP information were facilitators of PrEP promotion, while limited client interaction frequency/duration, privacy/confidentiality concerns, and anticipated PrEP stigma by clients inhibited PrEP promotion. Our capacity-strengthening intervention successfully increased PrEP knowledge, self-efficacy, and promotion among FHRW, affirming the adaptability and feasibility of integrating our training toolkit into FHRW practice across implementation settings.

RESUMO

Community mobilization (CM) is a vital yet under-explored avenue for increasing HIV testing in generalized HIV epidemic settings. Using multi-stage cluster sampling, a population-based sample of 3535 Zambian adults (mean age: 28 years, 50% women) were recruited from 14 districts to complete a household survey. Exploratory factor analysis (EFA) was used to re-validate a 23-item, 5-factor CM scale. Multivariable logistic and Poisson regression were then used to identify associations of CM with HIV testing behaviors and their psychosocial antecedents. A 21-item, 3-factor ("Leadership", "Collective Action Capacity", and "Social Cohesion") CM solution emerged from EFA (Cronbach's α 0.88). Among men and in rural settings, higher CM was significantly (p < 0.05) associated with elevated odds of HIV testing and more past-year HIV testing discussion sources, controlling for socio-demographics and sexual behaviors. Results underscore the importance of prioritizing CM to cultivate more favorable environments for HIV testing uptake, especially for men and rural residents.

RESUMO

Assess the preliminary impact of Brave Technology Co-op's overdose detection devices that have been implemented in housing, medical, social service facilities, and several private settings in North America. Administrative data was collected by Brave on their Buttons and Sensors during several proof-of-concept projects and full installations in Canada and United States (US) between December 2018 and July 2022. Data analyzed provided insights on the number of overdoses detected and reversed (averted overdose deaths) using Brave Sensors and Buttons, along with other programmatic and session-specific indicators. Implementation of 486 Brave Buttons and 148 Brave Sensors in Canada has detected and prevented 108 overdose deaths (100 using Buttons and 8 using Sensors) whereas implementation of 170 Buttons in the US has averted 2 overdose deaths to date, with the potential to save many more lives. Brave's devices hold promise for increasing rates of overdose detection and preventing overdose deaths.

RESUMO

BACKGROUND: Advancing the health of adolescents, particularly their sexual and reproductive health, including HIV prevention and care, is a development imperative. A critical part for improving their wellbeing and economic development is the social status accorded to adolescent girls and young women (AGYW). However, AGYW in many countries including Zambia, encounter health challenges that stem from gender inequalities, lack of empowerment, inaccurate knowledge on sexuality, and poor access to sexual and reproductive health (SRH) services and information. Addressing the knowledge gaps through comprehensive sexuality education (CSE) and improving access to SRH services and appropriate information, should reduce school attrition from early and unintended pregnancies (EUP) and enhance realization of their full potential. METHODS: The aim was to reduce EUP and improve SRH outcomes among AGYW in Zambia through provision of CSE linked to receptive SRH services. A 3-Arm randomized control study collected cross-sectional data at baseline, midline and Endline. Schools where CSE was being routinely provided were randomized into a non-intervention arm (arm1), an intervention arm in which information on available SRH services was provided in schools by health workers to complement CSE, (arm 2), and arm 3 in which pupils receiving CSE were also encouraged or supported to access pre-sensitized, receptive SRH services. RESULTS: Following 3 years of intervention exposure (CSE-Health Facility linkages), findings showed a significant decline of in-school pregnancies amongst AGYW in both intervention arms, with arm two exhibiting a more significant decline, having recorded only 0.74% pregnancies at endline (p < 0.001), as well as arm 3, which recorded 1.34% pregnancies (p < 0.001). No significant decline was recorded in the CSE only control arm. Trends in decline of pregnancies started to show by midline, and persisted at endline (2020), and when difference in differences test was applied, the incident rate ratios (IRR) between the none and exposed arms were equally significant (p < 0.001). CONCLUSION: Linking provision of CSE with accessible SRH services that are receptive to needs of adolescents and young people reduces EUP, which provides the opportunity for higher retention in school for adolescent girls.


Among Zambia's key health and development challenges, are high rates of EUP, and disproportionately higher HIV rates among AGYW. Pregnancy among girls in school poses a challenge. CSE programmes are part of available armamentarium to improve knowledge on the risks. Poor SRH places a heavy strain on health systems and undermines sustainable development efforts. In response to these challenges, we initiated implementation research to develop and test a model linking CSE programs in schools with access to SRH services and information. Research was conducted in 23 schools and their local catchment health care facilities in two North Western province districts of Zambia. Following baseline data collection, schools were selected to ensure comparability of indicators such as reported pregnancy rates, CSE, and subsequently randomized into three study arms, with the first arm continuing standard instruction of CSE (control). The second arm was designed to bring information on available SRH services to schools, including raising awareness through health fares and clubs. In the third arm, health providers were trained to be more receptive to ASRH health needs, in addition to encouraging teachers to introduce students to health services. Pregnancies declined in all intervention arms at endline, with marked reductions in intervention Arm 2 which recorded 0.74% of in school pregnancies (p < O.001), followed by arm 3, with 1.34% (p < 0.001). The decline in intervention arms was more than 50% in intervention arms, as compared with control arm, and significantly lower, as a proportion of AGYW in arm 2, followed by arm 3.

RESUMO

Women in the USA represent 15% of new HIV diagnoses but only 5% of pre-exposure prophylaxis (PrEP) users. We sought to characterise communicative appeals and messaging frames used in US visual media to cultivate PrEP demand among cisgender and transgender women using content analysis methodology. We catalogued and coded media items (images and videos) from US PrEP marketing campaigns featuring women. Production and content characteristics were abstracted, and communicative appeals from media items were qualitatively coded in duplicate. We then descriptively summarised production and content characteristics and identified discrete subgroups of media items, clustering around specific messaging frames, through qualitative thematic analysis. Racial/ethnic minorities and sexual/gender minority women were heavily featured, and numerous media items leveraged cognitive and social communicative appeals to promote PrEP. We identified three unique messaging frames emerging from coded media items, portraying PrEP as: (1) necessary prevention (protection frame), (2) a desirable yet accessible commodity (aspiration frame), and (3) a conduit to sexual autonomy (empowerment frame). To effectively communicate PrEP information and promote PrEP to women, PrEP marketing should leverage alternative appeals (subjective norms, self-efficacy), address anticipated barriers to uptake (stigma, cost, medication interactions), and deconstruct misconceptions of PrEP use(rs).

RESUMO

BACKGROUND: The COVID-19 pandemic disrupted healthcare and substance use services engagement, including primary and mental health services as well as residential and outpatient drug treatment. Women who inject drugs (WWID) face known barriers to healthcare and substance use service engagement, which pre-date the COVID-19 pandemic. The impact of COVID-19 on WWID's engagement with healthcare and substance use services, however, remains understudied. METHODS: To explore the impact of the COVID-19 pandemic on service-seeking and utilization, we conducted in-depth interviews with 27 cisgender WWID in Baltimore, Maryland, in April-September 2021. Iterative, team-based thematic analysis of interview transcripts identified disruptions and adaptations to healthcare and substance use services during the COVID-19 pandemic. RESULTS: The COVID-19 pandemic disrupted service engagement for WWID through service closures, pandemic safety measures restricting in-person service provision, and concerns related to contracting COVID-19 at service sites. However, participants also described various service adaptations, including telehealth, multi-month prescriptions, and expanded service delivery modalities (e.g., mobile and home delivery of harm reduction services), which overwhelmingly increased service engagement. CONCLUSION: To build upon service adaptations occurring during the pandemic and maximize expanded access for WWID, it is vital for healthcare and substance use service providers to continue prioritizing expansion of service delivery modality options, like telehealth and the provision of existing harm reduction services through alternative platforms (e.g., mobile services), that facilitate care continuity and increase coverage.

RESUMO

Despite growing availability, HIV pre-exposure prophylaxis (PrEP) uptake and adherence remains suboptimal among female sex workers (FSW) in the United States. Using cross-sectional data from a survey of 236 street-based cisgender FSW in Baltimore, Maryland, we examined interest in event-driven and long-acting PrEP formulations. Latent class analysis identified discrete patterns of interest in five novel PrEP agents. Multinomial latent class regression then examined factors associated with probabilistic class membership. A three-class solution emerged as the best-fit latent class model: Injectable Acceptors (~ 24% of sample), Universal Acceptors (~ 18%), and Non-Acceptors (~ 58%). Compared to Non-Acceptors, Universal Acceptors had significantly (p < 0.05) higher odds of reporting condomless vaginal sex with clients, client condom coercion, and client-perpetrated physical violence. Relative to Non-Acceptors, Injectable Acceptors were distinguished by significantly higher rates of condomless vaginal sex with clients and injection drug use. Expanding PrEP options for FSW could help overcome barriers to PrEP initiation and persistence.

RESUMO

BACKGROUND: Transactional sex is an important driver of HIV risk among people who use drugs in the USA, but there is a dearth of research characterizing men's selling and trading of sex in the context of opioid use. To identify contextually specific factors associated with selling or trading sex in a US population of men who use drugs, we cross-sectionally examined social and structural correlates of transactional sex among men who use opioids (MWUO) in Anne Arundel County and Baltimore City, Maryland. METHODS: Between July 2018 and March 2020, we used targeted sampling to recruit men reporting past-month opioid use from 22 street-level urban and suburban recruitment zones. MWUO completed a 30-min self-administered interview eliciting substance use histories, experiences with hunger and homelessness, criminal justice interactions, and transactional sex involvement. We identified correlates of recent (past 3 months) transactional sex using multivariable log-binomial regression with cluster-robust standard errors. RESULTS: Among 422 MWUO (mean age 47.3 years, 73.4% non-Hispanic Black, 94.5% heterosexual), the prevalence of recent transactional sex was 10.7%. In multivariable analysis, younger age (adjusted prevalence ratio [aPR] 0.98, 95% confidence interval [95% CI] 0.97-0.99, p < 0.001), identifying as gay/bisexual (aPR = 5.30, 95% CI 3.81-7.37, p < 0.001), past-month food insecurity (aPR = 1.77, 95% CI 1.05-3.00, p = 0.032), and injection drug use in the past 3 months (aPR = 1.75, 95% CI 1.02-3.01, p = 0.043) emerged as statistically significant independent correlates of transactional sex. CONCLUSIONS: Synergistic sources of social and structural marginalization-from sexuality to hunger, homelessness, and injection drug use-are associated with transactional sex in this predominantly Black, heterosexual-identifying sample of MWUO. Efforts to mitigate physical and psychological harms associated with transactional sex encounters should consider the racialized dimensions and socio-structural drivers of transactional sex among MWUO.

RESUMO

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.

RESUMO

BACKGROUND: Climate-induced disruptions like drought can destabilize household and community livelihoods, particularly in low- and middle-income countries. This qualitative study explores the impact of severe and prolonged droughts on gendered livelihood transitions, women's social and financial wellbeing, and sexual and reproductive health (SRH) outcomes in two Zambian provinces. METHODS: In September 2020, in-depth interviews (n = 20) and focus group discussions (n = 16) with 165 adult women and men in five drought-affected districts, as well as key informant interviews (n = 16) with civic leaders and healthcare providers, were conducted. A team-based thematic analysis approach, guided by the Framework Method, was used to code transcript text segments, facilitating identification and interpretation of salient thematic patterns. RESULTS: Across districts, participants emphasized the toll drought had taken on their livelihoods and communities, leaving farming households with reduced income and food, with many turning to alternative income sources. Female-headed households were perceived as particularly vulnerable to drought, as women's breadwinning and caregiving responsibilities increased, especially in households where women's partners out-migrated in search of employment prospects. As household incomes declined, women and girls' vulnerabilities increased: young children increasingly entered the workforce, and young girls were married when families could not afford school fees and struggled to support them financially. With less income due to drought, many participants could not afford travel to health facilities or would resort to purchasing health commodities, including family planning, from private retail pharmacies when unavailable from government facilities. Most participants described changes in fertility intentions motivated by drought: women, in particular, expressed desires for smaller families, fearing drought would constrain their capacity to support larger families. While participants cited some ongoing activities in their communities to support climate change adaptation, most acknowledged current interventions were insufficient. CONCLUSIONS: Drought highlighted persistent and unaddressed vulnerabilities in women, increasing demand for health services while shrinking household resources to access those services. Policy solutions are proposed to mitigate drought-induced challenges meaningfully and sustainably, and foster climate resilience.

Reaching ambitious voluntary medical male circumcision (VMMC) coverage targets requires a deeper understanding of the multifaceted processes shaping men's willingness to access VMMC. Guided by the Ideation Model for Health Communication, this population-based study identifies correlates of Zambian men's future VMMC intentions. Multistage cluster sampling was used to identify households with adult men in 14 districts. Multivariable Poisson regression with robust standard errors modelled associations of future VMMC intent with ideational factors (e.g. perceived benefits and barriers) and sexual behaviours respectively. Forty per cent (40%) of uncircumcised men (N = 1 204) expressed future VMMC intentions. In multivariable analysis, VMMC intent was associated with secondary education or higher (Adjusted Prevalence Ratio [APR] 1.30, 95% Confidence Interval [95% CI]: 1.02-1.66), perceiving VMMC to increase sexual satisfaction (APR 1.45, 95% CI: 1.11-1.89), reporting distance to services as a barrier to VMMC uptake (APR = 0.54, 95% CI: 1.27-1.87), unprotected last sex (APR 1.54, 95% CI: 1.11-2.14), and ≥ 2 sexual partners in the past 12 months (APR 1.45, 95% CI: 1.05-1.99). Being aged ≥ 45 years (vs 18-24 years: APR 0.23, 95% CI: 0.13-0.40) and perceiving that circumcision: (1) is unimportant (APR 0.71, 95% CI: 0.51-0.98); (2) is incompatible with local customs (APR 0.41, 95% CI: 0.18-0.94); or (3) reduces sexual satisfaction (APR 0.10, 95% CI: 0.02-0.62) were inversely associated with future VMMC intent. Demand-creation efforts must confront salient cognitive and social barriers to VMMC uptake, including concerns around incompatibility with local customs. Simultaneously, promotional efforts should emphasise relevant VMMC benefits beyond HIV prevention that resonate with men (e.g. penile hygiene) without reinforcing harmful gender norms.

RESUMO

BACKGROUND: Despite available control strategies, malaria morbidity and mortality, especially in infants and young children in sub-Saharan Africa, remain intractable. Malaria vaccination could substantially reduce malaria episodes and deaths. One vaccine candidate is the whole sporozoite PfSPZ Vaccine, consisting of irradiated cryopreserved sporozoites administered by direct venous inoculation (DVI). DVI may be less acceptable than more familiar administration routes, particularly intramuscular. As part of a PfSPZ Vaccine trial among infants in western Kenya, a qualitative study was conducted to explore caregiver and community perceptions of the malaria vaccine trial, including the unique DVI administration procedure. METHODS: Twelve focus groups and 28 in-depth interviews explored perceptions of the DVI procedure in infants, factors influencing trial acceptability, and barriers to sustained trial participation. Purposively sampled participants included mothers of enrolled children, fathers and mothers who withdrew their children from the trial, village elders, and study clinicians from two trial enrollment sites. An iterative, multi-stage analytic approach, adapted from the Framework Method, was used to synthesize and interpret textual data. RESULTS: Desires to prevent malaria and participation incentives (e.g., free consultations and medication) motivated caregivers to enroll their children in the trial. However, numerous factors also demotivated trial participation. Family members' (i.e., fathers') objections to required blood draws were cited most frequently as drivers of early trial withdrawal, in many cases prior to receiving any vaccine. Among mothers whose children received PfSPZ Vaccine (or placebo), many spoke favourably of DVI administration, describing improved tolerability relative to intramuscularly administered immunizations. Other trial-related challenges cited by caregivers included negative interactions with study clinicians and perceived delays in administering trial procedures. CONCLUSIONS: Despite high acceptance of DVI among caregivers whose children received PfSPZ Vaccine (or placebo), objections to trial procedures from other non-sensitized household and family members prompted early trial withdrawal and inhibited successful completion of trial procedures for some infants. Implications for future trials include targeting heads of household during sensitization and recruitment activities, as well as equipping trial staff to effectively respond to participant and community concerns regarding trial procedures.

RESUMO

Voluntary medical male circumcision (VMMC) is an HIV prevention priority in Lesotho, but uptake remains suboptimal. We analyzed the 2014 Lesotho Demographic and Health Survey to assess population-level social, behavioral, and serological correlates of circumcision status, specifically traditional and/or medical circumcision. Among 2931 men, approximately half were traditionally circumcised, and fewer than 25% were medically circumcised. Only 4% were dually (traditionally and medically) circumcised. In multivariate analysis, only medical circumcision emerged as significantly (p < 0.05) protective against HIV infection, whereas dual circumcision was significantly associated with past-year STI symptomology. Younger (ages 15-24), lower educated, rural-dwelling, and traditionally circumcised men, including those who never tested for HIV, had significantly lower odds of medical circumcision. Our findings indicate other unmeasured behavioral factors may mitigate VMMC's protective effect against HIV and STI infections in dually circumcised men. Further research can help identify counseling and demand creation strategies for traditionally circumcised men presenting for VMMC.

RESUMO

Male clients of female sex workers (CFSWs) are a key-affected group within the HIV epidemic. However, few studies have quantified HIV/STI burdens among CFSWs. This study used nationally representative data from the 2013-14 Zambia Demographic and Health Survey to estimate proxies for HIV and STI prevalence among sexually active men aged 15-59 paying for sex recently (past 12 months) [5%, n = 679] or in their lifetime [15%, n = 1,887]. Chi-square tests were calculated to assess differences in prevalence estimates between CFSWs and non-clients. Multivariable logistic regression models were generated to identify sociodemographic factors associated with prevention characteristics. CFSWs had higher odds of reporting HIV infection (recent: aOR 1.413, p < 0.05; lifetime: aOR 1.604, p < 0.001) and past-year STI symptomology (recent: aOR 3.342, p < 0.001; lifetime: aOR 2.266, p < 0.001) than non-clients, irrespective of transactional sex recency. Compared to non-clients, CFSWs were more likely to be <25yo (42% vs. 29%, p < 0.001), have a cohabitating partner (43% vs. 35%, p < 0.001), use condoms at last sex (31% vs. 27%, p < 0.001), and never test for HIV (36% vs. 29%, p < 0.001). When comparing CFSWs to non-clients, marital status was an effect modifier of HIV testing, medical circumcision, and condom use at last sex. Findings suggest high HIV/STI burdens and highlight the urgent need for differentiated HIV prevention programming for CFSWs in Zambia including the provision of PrEP.
