INTRODUCTION: This study compares anthropometric, metabolic, cardiovascular, and liver parameters in people living with HIV (PLWH) on antiretroviral therapy (ART), and men on pre-exposure prophylaxis (PrEP) in the same age group. METHODS: . Group differences were assessed using chi-squared, t tests, and Mann-Whitney tests, while logistic regression determined associations with HIV status. RESULTS: Eighty-two participants were enrolled: 53 PLWH and 29 PrEP users. PLWH had significantly higher BMI, waist circumference, total fat mass, and triglycerides, as well as total and LDL cholesterol. PrEP users engaged in more vigorous-intensity activity, with no differences in dietary habits. Among PLWH, higher physical activity was associated with lower HOMA index. Leptin levels were significantly higher in PLWH compared to PrEP users. Multivariate analysis identified LDL cholesterol as independently associated with HIV status. CONCLUSION: PLWH exhibited greater adiposity and dyslipidemia than PrEP users, with leptin emerging as a potential marker of metabolic dysfunction. Higher physical activity was linked to improved insulin sensitivity, underscoring the role of exercise in mitigating HIV-related metabolic dysregulation.
