Integration of a task strengthening strategy for hypertension management into HIV care in Nigeria: Baseline characteristics of participants in a cluster randomized controlled trial.

BACKGROUND

Improved access to antiretroviral therapy (ART) has increased survival among people living with HIV (PLWH) but also the burden of cardiovascular risk factors like hypertension. While the task-strengthening strategy for hypertension control (TASSH) is a viable integrated care model, evidence of its clinical impact in Africa is limited. This report presents baseline findings from a trial evaluating 2 implementation strategies for integrating TASSH into HIV care across primary health centers (PHCs) in Lagos, Nigeria.

METHODS

A total of 3,504 PLWH on antiretroviral therapy in 30 PHCs were screened, and 830 were enrolled. Baseline data on patient sociodemographic, clinical, laboratory results, and lifestyle characteristics were gathered.

RESULTS

Among the 3,504 screened, 1,046 (29.9%) had hypertension. Of the 830 enrolled, mean [SD] age was 49.4 [9.5] years, 63.5% were women, 69.5% had at least secondary school education, 92.3% were employed, and 84.6% earned less than 100,000 Naira (64.74 USD) monthly. The median BP was 150.0/95.3 mmHg, and 63.9% were overweight or obese. 25.8% continued previously prescribed antihypertensive medications, while 66.3% received new prescriptions. Additionally, 25.1% and 1.8% were alcohol users and current smokers, while 30.9% were physically inactive.

CONCLUSIONS

The prevalence of hypertension among PLWH was higher than previously reported. Although most participants adopted healthy lifestyle behaviors, the majority were overweight or obese, and many were not on antihypertensive medications. These findings highlight the importance of integrating hypertension control into HIV care across PHCs in Nigeria.
