Factors that Affect Compliance with Blood Pressure Control in Hypertensive Patients in the Working Area of Bawomataluo Community Health Center, South Nias Regency-Indonesia

Hypertension has become a significant public health issue, with cases steadily increasing in the Bawomataluo Public Health Center’s working area from 2022 to 2024. The condition presents a high risk of severe complications such as heart disease, stroke, kidney failure, and other organ damage. This study aimed to identify the factors that influence compliance with blood pressure control among hypertensive patients in Bawomataluo Public Health Center, South Nias Regency, in 2025. A quantitative approach was utilized, with an analytic survey design and a cross-sectional approach. The study population consisted of 185 hypertensive patients diagnosed over the last six months (from July to December 2024). Using purposive sampling, 127 participants were selected. The data were analyzed using univariate, bivariate, and multivariate analyses, including logistic regression with the forward method. The results revealed that knowledge (p = 0.002, Exp(B) = 5.680), family support (p = 0.000, Exp(B) = 6.740), motivation (p = 0.000, Exp(B) = 6.947), and self-confidence (p = 0.001, Exp(B) = 5.706) significantly influenced compliance with blood pressure control. Among these, motivation was identified as the most dominant factor, with the highest odds ratio. The study concluded that knowledge, family support, motivation, and self-confidence all had significant impacts on compliance with blood pressure control. Therefore, it is recommended that the Bawomataluo Public Health Center enhance support for hypertensive patients, with a focus on providing motivation to improve compliance with treatment.
