Traditional and psychosocial factors associated with non-communicable diseases among people living with HIV in Cambodia: a cross-sectional study

We examined traditional and psychosocial factors associated with self-reported diabetes, hypertension, raised cholesterol, and multimorbidity among 4,089 people living with HIV in Cambodia. Participants were recruited from 20 antiretroviral therapy (ART) clinics across nine provinces and the capital city in 2021. Multiple logistic regression analyses assessed the associations between sociodemographic variables, HIV-related information, and psychosocial factors with the outcome variables. The prevalence of diabetes, hypertension, and raised cholesterol were 7.8%, 16.9%, and 6.6%, respectively. Non-adherence to ART (adjusted odds ratio [aOR]: 1.55, 95% confidence interval [CI]: 1.04-2.32), low self-efficacy in attending ART clinics regularly (aOR: 2.02, 95% CI: 1.16-3.53), and poor quality of life (aOR: 1.48, 95% CI: 1.13-1.94) were significantly associated with all outcomes. Interestingly, lower perceived social support was significantly associated with lower odds of hypertension (aOR: 0.52, 95% CI: 0.33-0.83) and multimorbidity (aOR: 0.40, 95% CI: 0.20-0.80). Past experiences with HIV-related stigma and discrimination were significantly associated with a higher likelihood of diabetes (aOR: 1.97, 95% CI: 1.23-3.15) and multimorbidity (aOR: 1.87, 95% CI: 1.23-2.85). Community-based interventions to enhance peer support and reduce stigma and discrimination may help decrease non-communicable diseases (NCDs), and integrating HIV and NCD programs could improve healthcare access among people living with HIV.
