Introduction
Diabetes and hypertension are prevalent non-communicable diseases that significantly affect people living with HIV, particularly those on antiretroviral therapy. Despite the increasing recognition of these conditions, their prevalence and associated risk factors among people living with HIV in Tanzania remain underexplored. This study aimed to determine the prevalence and risk factors of diabetes and hypertension among HIV patients attending Child-Centred Family Care Clinic at KCMC Hospital.
Methods
A cross-sectional study was conducted from May to June 2024, involving 341 people living with HIV attending the Child-Centred Family Care Clinic at KCMC Hospital. Data were collected through face-to-face interviews, file reviews, and physical measurements. Hypertension was defined as systolic blood pressure ≥ 140 mmHg/ or diastolic blood pressure ≥ 90 mmHg. Diabetes was defined as blood glucose level of ≥140 mg/dL. A logistic regression model was used to identify factors associated with diabetes and hypertension.
Results
Prevalence of hypertension was 23.5% (80) while the prevalence of 14.1% (48) was diabetes. Hypertension was most prevalent in individuals aged 36-62 years (71.3%), whereas 70.9% of diabetic patients reported a family history of diabetes. Multivariate analysis revealed that older age was significantly associated with hypertension, with participants aged 18-35 years showing a lower likelihood of hypertension (AOR=0.10; 95% CI: 0.03-0.41; p=0.004) compared to those over 63 years. Participants earning TZs 500,000 or more per month were more likely to develop diabetes as compared to others (AOR=4.112; 95% CI: 1.199-14.108; p=0.025).
Conclusion
The findings indicate that socioeconomic determinants are critical in influencing the prevalence of diabetes and hypertension among people living with HIV, suggesting that interventions should focus on improving screening and early treatment to at risk groups.
