INTRODUCTION: HIV-infection and treatment with antiretroviral therapy (ART) are risk factors for the development of hypertension, which is more prevalent in people living with HIV compared with the general population. Although there is a shift to Integrase Strand Transfer Inhibitor (INSTI)-based ART across the sub-Saharan Africa, there is limited information with regard to INSTIs and hypertension association in this region, making this, a critical question to address. Hence, the study aimed to determine the relationship between hypertension and ART regimen in people living with HIV. METHODS: this was a cross-sectional study conducted at the Livingstone Central Hospital, southern province of Zambia. This study utilized programmatic data. Demographic and clinical data of 348 persons living with HIV who had been on ART for more than 2 years was abstracted in the adult ART database registry. Descriptive and inferential statistics were used for analyses of data. RESULTS: prevalence of hypertension was 18.4% (n=64). Hypertensives were older than normotensives with median (interquartile range) age of 55 (49, 61) and 46 (41, 52), respectively. At multivariate analysis, age (aOR: 1.07, 95% CI 1.04-1.11; p = 0.001) and body mass index (aOR: 1.10, 95% CI 1.04-1.16; p = 0.002) were positively associated with hypertension. Participants on dolutegravir based regimen were 2 times (aOR: 2.44, 95% CI 1.22-4.86; p = 0.01) more likely to be hypertensive compared to those on non-nucleoside reverse transcriptase inhibitors (efavirenz or nevirapine). CONCLUSION: we confirm that increasing age, body mass index (BMI) and use of dolutegravir are risk factors for hypertension. Close monitoring for persons with HIV with these known risk factors is required.
