Quality of life and HIV adherence self-efficacy in adolescents and young adults living with perinatal HIV in Chiang Mai, Thailand.

We assessed the quality of life and HIV adherence self-efficacy of adolescents and young adults (AYA) with perinatal HIV infection (PHIV). This cross-sectional study was conducted in Chiang Mai, Thailand. AYA-PHIV aged between 15 and 25 years were enrolled, who all were initiated on antiretroviral treatment as children. The World Health Organization-quality of life-BREF questionnaire and the HIV Treatment Adherence Self-Efficacy Scale (HIV-ASES) were administered. A total of 111 AYA-PHIV were included, including 52 (47%) females. Their median age was 20.2 ± 2.6 years. The overall QOL was rated as favorable (good or very good) by 59.4% of AYA-PHIV. The highest score was seen in the social relationships domain followed by the environmental health domain. Males had a significantly lower score in the psychological health domain than females ( = 0.018). Simple linear regression revealed a negative association between male sex, physical, and psychological health domain scores. The overall mean HIV-ASES score was 7.79 ± 1.96 out of 10, with a trend toward lower scores in males ( = 0.062), and a weak positive correlation with QOL. Our study documented worse QOL and lower HIV adherence self-efficacy in male AYA-PHIV. The findings call for the design of tailored male-focused interventions.
