Hypertension Occurrence and Associated Risk Factors in HIV Patients on Antiretroviral Therapy in Nairobi County, Kenya
Main Article Content
Abstract
Due to advances in antiretroviral treatment, the incidence of HIV infection has declined in recent years. However, cardiovascular illnesses continue to be the primary cause of death and morbidity among HIV-positive individuals, accounting for 10% of all deaths that are not related to AIDS. The paper aimed to determine occurrence and risk factors associated with hypertension among HIV patients on antiretroviral treatment in Nairobi County. The study adopted a cross-sectional design, and a sample size of 552 respondents. Purposive sampling technique was used to select the area, and systemic random sampling was used to select participants. Structured questionnaires were used to collect data, which was analyzed using excel and SPSS. Results indicated (64.86%) female and 35.69% male participants. About 55.43% participants were married, 61.41% had informal jobs, 43.48% had attained elementary school level, and 99.64% identified as Christians. Accordingly, 14.52% of people had elevated blood pressure, and 85.48% recorded normal blood pressure. About 44.21% of people were overweight/obese as indicated by their waist circumference and BMI findings, and 24.64% were at risk because of their elevated waist circumference. The risk of hypertension is substantially higher among respondents 46 years and older than in respondents under 25 years (p = 0.008) at 95%CL. A higher waist circumference is linked to a higher risk of hypertension (p = 0.012), family history (p=0.021) Cl, whereas a person's chance of developing hypertension is higher when their heart rate remains constant than when it changes slightly (p = 0.036). In conclusion, advancing age, female gender, increase in waist circumference, overweight/obesity and family history were predictors for hypertension in this study. The study recommended Nairobi health service to integrate hypertension and HIV services; to give health education to patients and care givers and promote lifestyle modification; and the Ministry of Health (MoH) to formulate integration policies.
