Predictors of Stigma and Health-Related Quality of Life Among People Living with HIV in Northern Thailand

Abstract

HIV-related stigma and discrimination have been a significant barrier to accessing health care, hence contributing to poor health outcomes. This study aimed to investigate factors associated with HIV-related stigma and discrimination and health-related quality of life (HRQoL) among people living with HIV in rural Thailand setting. A cross-sectional convenience sample of 161 HIV-positive Thai patients was recruited from a single rural district hospital using a self-administered questionnaire entailing sociodemographic information, the 12-item stigma scale, the Medical Outcomes Study HIV Health Survey (MOS-HIV), and the EuroQoL 5-Dimension 5-Level (EQ-5D-5L). Linear regression and the multi-variable analyses were used to investigate factors associated with stigma and HRQoL, whereas the correlations between stigma and quality of life variables were tested by Pearson correlations. Being married and duration of antiretroviral therapy were negatively correlated with HIV stigma, while increased age was inversely associated with HRQoL. Being employed and having sufficient money for living contributed positively to predict HRQoL. HIV stigma was negatively associated with mental health summary (MHS) and visual analog scale (VAS) score, whereas duration diagnosed with HIV and the use of two nucleoside reverse transcriptase inhibitors in combination with protease inhibitor regimen were negative factors associated with VAS and health utility, respectively. The findings confirm complex and inseparable associations of factors relating to HIV-related stigma and HRQoL. The development of effective interventions tailored at individual level is warranted to address this gap.
