RESUMO
BACKGROUND: Adherence to antiretroviral therapy (ART) has individual and public health benefits and is critical to improving life expectancy, achieving viral suppression, and reducing the risk of HIV transmission. This qualitative study explored the experience of receiving care as well as perceived facilitators and barriers of treatment initiation, retention in ART care, and adherence to treatment. METHODS: In-depth interviews were conducted among 28 men who have sex with men (MSM) and female sex workers (FSWs) receiving ART services in Lagos and Benue states. Key informant interviews were also conducted among 16 service providers engaged in counselling, clinical care, and ART treatment for MSM and FSWs. The Social Ecology Model guided the exploration of perceived barriers and facilitators of treatment initiation, retention in ART care and adherence to treatment. Qualitative data analysis was managed using NVIVO 11 software and themes were analysed using thematic analysis. RESULTS: We found that the key barriers to ART adherence were low motivation to comply with medication regimen, work commitments, socioeconomic factors, stigma, negative provider attitude and distance to health facilities. Facilitators of adherence identified include the desire to live a productive life, strong family support and participation in support group programs. Comprehensive adherence counselling, support group programs and an effective follow-up system were factors identified by service providers as key to facilitating adherence. CONCLUSION: To be effective, ART programs must address the unique challenges key populations face in accessing treatment and achieving optimal adherence regarding establishing a strong support system and follow-up. Community level interventions that support a stigma-free environment are critical to sustaining engagement in care.
RESUMO
BACKGROUND: Men who have sex with men (MSM) are conservatively estimated to be less than 1% of the Nigerian population yet nationally account for about 20% of new HIV infection. We estimated the trend in HIV prevalence and determined correlates of HIV infection among MSM. METHODS: This study used data from respondent-driven sampling in three rounds of integrated biological and behavioral surveillance survey (2007, 2010 and 2014) and covered three states in 2007, six states in 2010 and eight states in 2014. Each round used similar methodology and thus allows for comparison. Behavioral data were obtained using a structured pre-coded questionnaire. Differences in categorical variables were assessed with Chi Square. Logistic regression was used to identify factors associated with HIV. RESULTS: A total of 879, 1545 and 3611 MSM were recruited in 2007, 2010 and 2014 respectively. Median age was 22 years for 2007 and 2014 while it was 24 years in 2010. About one-third of MSM in 2007 and 2014 and about two-fifths in 2010 had engaged in transactional sex. HIV prevalence increased from 14% in 2007 to 17% in 2010 to 23% in 2014 (p < 0.0001). Factors associated with HIV include older age ≥ 25 years (adjusted odds ratio {AOR}:2.41; 95% CI:1.84-3.16); receptive anal sex (AOR:1.92; 95% CI:1.54-2.40) and history of sexually transmitted infections (AOR:1.26; 95% CI:1.02-1.55). CONCLUSION: There's been a consistent and significant increase in HIV prevalence among MSM with about 10-percentage points relative increase per year over 7 years. Older MSM were more likely to be HIV positive and this may reflect their prolonged exposure to high risk sexual activities. Evidence based interventions are urgently needed to mitigate intra-group HIV transmission and propagation of HIV epidemic between MSM and the general population.
