Abstract

Objective:

1- To determine the prevalence of medication adherence in hypertensive population.

Objective:

2- To study factors associated with medication adherence

Objective:

3- To describe the blood pressure control among hypertensive population.

Design and Method:

This was a cross-sectional study on adult hypertensive patients who attended the primary care clinic from 19th of October 2015 till 27th of November 2015. Convenient sampling was used. Social demographic data and blood pressure readings were extracted from patient's clinic record. Medication adherence was assessed using Eight Item Original Morisky Scale (MMAS-8). Blood pressures control was defined as <140/90 mmHg in non-diabetic and BP<140/80 mmHg for diabetic patients. MMAS-8 score was categorized as non-adherence (score <6) and adherence (score ≥6).

Results:

Total of 384 patients was recruited into this study. The mean age was 65.4 ± 10 years, of which half (53.4%) were 65 years or older. Half of them were female (55.8%) and 43% were Chinese. The prevalence of medication adherence was high (72%). Elderly (OR: 1.03, CI: 1.00 – 1.06, p<0.05), Chinese ethnicity (OR: 2.05, CI: 1.14 – 3.70, p < 0.05) and good medication knowledge (OR: 2.45, CI: 1.39 – 4.43, p < 0.05) were positively affecting medication adherence. However, despite good adherence, only 36% of them have blood pressure control.

Conclusions:

Despite good medication adherence, blood pressure control is poor. Many other factors could be potential reasons for poor control of blood pressure. Thus, further studies are needed to examine the reasons why blood pressure control is not better despite good medication adherence.
