Determinants of blood pressure control among hypertensive patients attending a rural teaching hospital in Southern Nigeria.

Abstract

Hypertension (HTN) is the commonest cardiovascular risk factor in sub-Saharan Africa. It is a global public health threat, often associated with significant morbidities and mortality with rising prevalence both in rural and semi-urban areas of economically disadvantaged countries. This study aimed to assess the determinants of blood pressure control among patients with hypertension receiving care at the Irrua Specialist Teaching Hospital in Southern Nigeria. A cross-sectional study of 502 consenting hypertensive adults receiving care at the Irrua Specialist Teaching Hospital, Irrua in Edo State, South-south Nigeria. A pre-tested semi-structured interviewer-administered questionnaire was used to collect data which was analyzed using SPSS version 21 and the level of significance was set at P < 0.05. Five hundred and two participants (226 males, 276 females) completed the study with a mean age of 52.98 ± 12.82 years. Optimal blood pressure control was found in 15.5% of the study participants. Blood pressure control was significantly associated with being married (OR 1.549, CI: 1.040-2.309), having a monthly household income of over N50,000 (OR 1.691, CI: 0.999-2.863), engaging in physical activity (OR = 1.537, CI: 0.989-2.388), and not being obese evidenced by a normal Waist Hip Ratio (OR = 2.276, CI: 1.555-3.332). Blood pressure control to target goal was low in the study population and achieved only in less than one-fifth of respondents on antihypertensive therapy. Numerous socio-demographic and lifestyle variables were shown to be associated with blood pressure control. Physicians should emphasize medication adherence and lifestyle modification approaches in hypertensive adults.
