Abstract

: Introduction: The HIV epidemic continues to disproportionately impact Latin‐American transgender women (TGW). We assessed factors associated with long‐term pre‐exposure prophylaxis (PrEP) engagement and adherence among TGW enrolled in the Implementation of PrEP (ImPrEP) study, the largest PrEP demonstration study in Latin America. Methods: HIV‐negative TGW aged ≥18 years reporting 1+eligibility criteria in the 6 months prior to enrolment (e.g. sex partner known to be living with HIV, condomless anal sex [CAS], transactional sex or having a sexually transmitted infection [STI]) who could safely take PrEP were enrolled. Follow‐up visits were conducted at 4 weeks and then quarterly. We conducted logistic regression to identify factors associated with long‐term PrEP engagement (3+ follow‐up visits in 52 weeks) and complete self‐reported adherence (no missed pills in the past 30 days) during follow‐up. For both outcomes, we constructed multivariable models controlling for country, socio‐demographics, sexual behaviour, substance use, STIs and self‐reported adherence at 4 weeks (long‐term engagement outcome only). Results: From March 2018 to June 2021, ImPrEP screened 519 TGW, enrolled 494 (Brazil: 190, Mexico: 66 and Peru: 238) and followed them for 52 weeks. At baseline, 27.5% of TGW were aged 18–24 years, 67.8% were mixed‐race and 31.6% had >secondary education. Most, 89.9% reported CAS, 61.9% had >10 sex partners and 71.9% reported transactional sex. HIV incidence was 1.82 cases per 100 person‐years (95% confidence interval [CI]: 0.76–4.38). Almost half of TGW (48.6%) had long‐term PrEP engagement, which was positively associated with reporting complete adherence at week 4 (aOR:2.94 [95%CI:1.88–4.63]) and was inversely associated with reporting CAS with unknown‐HIV partner (aOR:0.52 [95%CI:0.34–0.81]), migration (aOR:0.54 [95%CI:0.34–0.84]), and being from Mexico (aOR:0.28 [95%CI:0.14–0.53]). Self‐reported adherence was associated with TGW aged >34 (aOR:1.61 [95%CI:1.10–2.34]) compared to those aged 25–34 and those with >secondary education (aOR:1.55 [95%CI:1.10–2.19]) and was lower among TGW from Peru (aOR:0.29 [95%CI:0.21–0.41]) or reporting PrEP‐related adverse effects (aOR:0.63 [95%CI:0.42–0.92]). Conclusions: Although TGW were willing to enrol in ImPrEP, long‐term PrEP engagement and complete self‐reported adherence were limited, and HIV incidence remained relatively high. A successful HIV prevention agenda should include trans‐specific interventions supporting oral PrEP and exploring long‐acting PrEP strategies for TGW., INTRODUCTION HIV infection disproportionately impacts transgender women (TGW) worldwide, with HIV prevalence being 50 times greater than adults of reproductive age in low‐ and middle‐income countries (LMICs), such as those [...]

Abstract

Understanding the factors associated with pre-exposure prophylaxis (PrEP) adherence may help in the development of strategies to support, motivate and sustain PrEP use. This study estimated self-reported adherence, described perceived barriers and facilitators and investigated factors associated with adherence to daily oral PrEP among men who have sex with man (MSM) and transgender women after 1 year of PrEP use in Brazil. PrEP Brasil was a prospective, multicentre, open-label demonstration study with MSM and transgender women at high risk for HIV infection. We used logistic regression to evaluate factors associated with complete adherence (not forgetting to take any pills in the past 30 days) at week 48. Of 338 participants included in this analysis, 60% reported complete adherence to daily oral PrEP at week 48. Perceived barriers and facilitators to daily oral PrEP were reported by 38.2% and 98.5%, respectively. The most reported barrier and facilitator were 'I forgot to take my pills' (19.2%) and 'Associate PrEP with a daily activity/task' (58.6%), respectively. In final multivariable analysis, living in Rio de Janeiro (aOR: 0.38; 95% CI: 0.20–0.73), being transgender women (aOR: 0.22; 95% CI: 0.07–0.73), reporting stimulant use (a OR: 0.40; 95% CI: 0.20–0.80) and having any perceived barriers to daily oral PrEP (aOR: 0.12; 95% CI: 0.07–0.23) were associated with decreased odds of complete adherence. Our findings provide information for developing the best practices to promote PrEP adherence in the Brazilian context. [ABSTRACT FROM AUTHOR]

Abstract

The HIV/AIDS epidemic among injection drug users (IDUs) in Brazil has been unique in terms of temporal and geographical contrasts. This analysis explores these contrasts through the use of multilevel modeling. Standardized AIDS incidence rates among IDUs for Brazilian municipalities (1986-2000) were used as the dependent variable, with a set of social indicators as independent variables (covariates). In some States of the North/Northeast, the epidemic among IDUs has been incipient. The São Paulo epidemic extended to reach a network of municipalities, most of which located far from the capital. More recently, on a smaller scale, a similar extension has been observed in the southernmost States of the country. Both "number of physicians per inhabitant" and "standard distance to the State capital" were found to be associated with AIDS incidence. AIDS cases among IDUs appeared to cluster in wealthier, more developed municipalities. The relative weight of such extensive dissemination in key, heavily populated States prevails in the Brazilian IDU epidemic, defining a central-western-southeastern strip of wealthier middle-sized municipalities and more recently a southern strip of municipalities deeply affected by the epidemic in this population. A epidemia de HIV/AIDS entre usuários de drogas injetáveis (UDIs) apresenta, no Brasil, contrastes temporais e geográficos. Esta análise explora tais complexidades, com o emprego de modelagem multinível. As taxas padronizadas de incidência de AIDS em UDIs para os municípios brasileiros (período 1986-2000) foram consideradas como variável-dependente, e um conjunto de indicadores sociais como covariáveis. Em alguns Estados do Norte e Nordeste, a epidemia é incipiente entre UDIs, enquanto a epidemia paulista atinge uma rede de municípios, a maioria deles distantes da capital. Mais recentemente, e em menor escala, disseminação análoga foi observada nos Estados mais meridionais. As covariáveis "número de médicos por habitante" e "distância-padrão da capital do respectivo estado" se mostraram associadas à variável-dependente. Os casos de AIDS entre UDIs parecem se concentrar em municípios mais ricos e bem equipados. O peso relativo dessa disseminação extensa em Estados-chave, populosos, prevalece sobre o conjunto da epidemia brasileira, definindo uma faixa que se estende do Centro-oeste ao Sudeste, com municípios mais ricos, de médio porte, e, mais recentemente, uma faixa sul de municípios substancialmente afetados pela epidemia entre UDIs.
