RESUMO
Introduction: depression may be associated with poor immune and virological response, poor quality of life and high medical costs in people living with HIV. The purpose of this study is to investigate the association between depression and viral load in people living with HIV on antiretroviral treatment followed at the Yaounde Central Hospital. Methods: we conducted a cross-sectional study of people living with HIV who had their viral load results at the Central Hospital of Yaounde over 8 months (November 2019 to July 2020). Before starting the study, informed consent was obtained from each participant. Sociodemographic, clinical, paraclinical and lifestyle data were collected. Depression was assessed using the Hospital Anxiety and Depression scale (HAD). Consecutive and non-probability sampling was used. Statistical analysis was performed using SPSS software version 23.0. A p-value < 0.05 was considered statistically significant. Results: of the 205 participants enrolled, female sex was the most represented (n=153, 74.6%) and the mean age was 46.5 ± 1.8 years. All participants had clinical stage I HIV and most of them had undetectable viral load (n=164, 80.0%). Definite depression was found in 4.8% of cases and people living with HIV with symptoms of definite depression were more likely to have a high viral load (OR = 14.24 [3.61-56.14]; p = <0.001). Conclusion: depression could be a leading cause of high viral load.
