Our study aimed to determine the role of sociodemographic characteristics on self-stigma among young men who have sex with men (MSM) living with HIV in Yogyakarta, Indonesia. This cross-sectional observational study was conducted from August-November 2022. Participants were recruited from outpatient clinics at Dr. Sardjito, Yogyakarta, Indonesia. The Indonesian version of the Berger HIV Stigma Scale measured self-stigma. The statistical analysis utilized a 95% confidence level and determined significance by p-values <0.05. 72 young MSM were enrolled and completed questionnaires assessing sociodemographic and self-stigma. The average self-stigma score was 98.97. Education level was significantly associated with severe self-stigma in the bivariate analysis (p < .05). In the multivariate analysis, those with higher levels of education were significantly more likely to experience severe self-stigma (r = 2.938, p < .05). Employment status, family support, and education level were significantly associated with increased concerns in the disclosure, negative self-image, and public attitudes subscales (all p < .05). The results demonstrate associations between sociodemographic and self-stigma levels among young MSM living with HIV in Yogyakarta, Indonesia. Further research regarding the educational level, employment status, and family support that can influence the perception and quality of life of PLHIV may need to be carried out.
