Abstract

Objective:

Hypertension has remained a leading cause of cardiovascular disease morbidity and mortality worldwide despite concerted efforts at control. Majority of the populace are unaware of their blood pressure (BP), others are not consistent with follow up and drug use. As part of 2015 world hypertension day theme of ‘know your number’, we undertook a study in 4 different locations in Abakaliki, Nigeria to evaluate the level of hypertension burden and drug adherence.

Design and Method:

Interviewer administered questionnaire was used to access knowledge of hypertension status, regularity with BP check, use of and adherence to therapy. Participant's height and weight were measured, BP checked using mercury in glass sphygmomanometer, and average of three measurements using standard protocol recorded as the person's BP. Data was then entered into a spread sheet for analysis. P value of <0.05 was considered significant.

Results:

The study involved 383 adults ≥ 18 years mean age 43 years, 55.8% (214) were females and the mean BMI was 23.9 kg/m2. Prevalence of hypertension was 47.5% (182), 16.7% (64) {95% CI 0.26–0.39] previously knew they were hypertensive. Mean age in those with elevated BP and those normal BP were 48 years and 38 years respectively. Among those previously diagnosed with hypertension, 81.3% have been commenced on anti-hypertensive drugs, but only 25% were compliant (p < 0.005). Mean BP was 129/81mmHg, 22.7% (87) and 12.5% (48) of cohorts had Grade1 and Grade 2 hypertension respectively, while 41.9% (18) and 31.3% of those regular and not regular with medications had Grade 2 hypertension. Mean of last blood pressure check among the participants (in weeks) was 33 weeks.

Conclusions:

Awareness of BP status and drug adherence remain poor among adults in south east Nigeria, calling for greater emphasis on campaign aimed at attitudinal change at every level in line with WHO emphasis on know your number.
