Predictors of blood pressure control amongst primary care patients of a teaching hospital in Bauchi, North-Eastern Nigeria

Abstract

Background: Poorly managed hypertension is still a serious global public health issue, despite medication. It is unclear what is causing treated hypertensive patients to have trouble achieving their target blood pressure (BP). Aim: The goal of this study was to determine the predictors of BP control amongst hypertensive patients attending a teaching hospital in North-eastern Nigeria. Materials and Methods: A cross-sectional study was conducted on 277 hypertensive patients from a tertiary healthcare institution. Data were analysed using version 20 of the Statistical Package for the Social Sciences (SPSS). Frequency and percentages were used to summarise data while Chi-square test was used to test for associations. To identify the factors linked to BP control, logistic regression was employed. At P < 0.05, predictors of BP control were found using adjusted odds ratios (AORs) with a 95% confidence interval (CI). Results: The respondents' average age was 53.1 ± 14.6 years, of which 67.5% were female. The level of optimal BP control was 40.8%. Factors associated with reduced BP control include not currently married (AOR = 0.29 [95% CI: 0.16-0.53], P ≤ 0.0001), imperfect adherence (AOR = 0.37 [95% CI: 0.22-0.64], P ≤ 0.0001), taking more than two drugs (AOR = 0.3 [95% CI: 0.14-0.64], P = 0.001) and body mass index (BMI) ≥25 kg/m2 (AOR = 0.40 [95% CI: 0.22-0.72], P = 0.002). Conclusion: The optimal BP control is alarmingly low in this setting. Marital status, medication adherence, increased pill burden and BMI ≥25 kg/m2 negatively affect the attainment of BP control.
