Abstract We followed adolescents and adults living with HIV aged older than 15 years who enrolled in a South African private-sector programme to examine adherence viral non-suppression (viral load > 400 copies/mL) of participants (20,743, 38%) without (33,635, 62%) mental health diagnoses. Mental diagnoses were associated unfavourable patterns. The risk was higher among patients organic disorders [adjusted ratio (aRR) 1.55, 95% confidence interval (CI) 1.22–1.96], substance use (aRR 1.53,...

Abstract Aims Prior research, largely focused on US male veterans, indicates an increased risk of cardiovascular disease among individuals with post-traumatic stress disorder (PTSD). Data from other settings and populations are scarce. The objective this study is to examine PTSD as a factor for incident major adverse events (MACEs) in South Africa. Methods We analysed reimbursement claims (2011–2020) cohort African medical insurance scheme beneficiaries aged 18 years or older. calculated...

Several studies have found lower prostate cancer diagnosis rates among men with human immunodeficiency virus (HIV; MWH) than without HIV but reasons for this finding remain unclear.

Background: The increased prevalence of physical diseases among individuals with mental illness contributes to their risk mortality. However, the mediating role specific in effect on mortality is not well understood. Method: We conducted a longitudinal causal mediation analysis using data from beneficiaries South African medical insurance scheme 2011 2020. estimated overall major depressive disorder (MDD) and evaluated reductions this through hypothetical interventions risks an...

Although the total number of suicides decreased since beginning 1980s, suicide-related behaviors using self-intoxication increased. Therefore, research on characteristics individuals committing becomes growing importance for risk assessments and development preventive measures. In this prospective, observational, monocentric cohort study, all incoming calls at our Poisons Control Centre reporting through self-intoxication, were analyzed via a standardized questionnaire over 12 months. Both...
