Abstract
INTRODUCTION: Although evidence suggested that lifestyle interventions can reduce blood pressure, there is little information about feasibility of such interventions on pre-hypertensive patients using the Information, Motivation and Behavioural Skills Model. By introducing lifestyle modification using the IMB Model this may increase healthy behaviour practice and prevent elevation of blood pressure. METHODS: A cluster RCT was conducted at health clinics in Maran in which 410 participants from 10 clinics were randomly allocated into intervention and control group. The intervention arm received the lifestyle intervention and the control received the usual care. The primary outcome was change in SBP and DBP. Secondary outcome was changes in behavioural factors and IMB score. Non-parametric analysis was used to compare the median within and between groups at three months follow up. Multivariable analysis was analysed using GEE. RESULTS: At three months follow up there was reduction of 3.75mmHg of systolic blood pressure as compared to baseline (p=0.01) and sodium reduction by 68mg as compared to baseline (p=0.001). There were significant group changes in information, motivation and behavioural skills score (p=0.001). DISCUSSION: The intervention was effective in increasing knowledge, motivation and acquiring the behavioural skills on healthy lifestyle to reduce blood pressure but not able to look into the effectiveness of changes in SBP and DBP. Findings suggest that implementation of IMB based intervention has potential benefits, but present gaps based on the result of study. Further long-term research is needed to determine the effect on SBP and impact on pre-hypertension prevalence in Malaysia.
