OBJECTIVES:  To evaluate the impact of a structured, group-based Hypertension Self-management Education (HSME) programme on participant’s clinical and psychosocial outcomes. METHODS:  A pre-post study design was employed. With the help of community leaders from non-governmental organisations in the state of Penang, adults diagnosed with hypertension and treated with anti-hypertensive(s) were recruited to participate in the study. Participants attended a total of 4-weekly (2-hour each session) of HSME programme. The programme was developed locally based on Bandura’s self-efficacy theory. Participant’s clinical (i.e. blood pressure, lipids, weight, body mass index, waist circumference, percentage body fat and percentage skeletal muscle) and psychosocial (hypertension self-care behaviour, self-care motivation, self-efficacy and quality-of-life) outcomes were assessed at baseline, post 1-week and post 2-month of HSME programme. RESULTS: A total of 45 participants consented to join the programme, with 36 (80.0%) attended two or more sessions. Most participants (68.9%) were female with a mean age 60±7.72 years old. Post 1-week of intervention, participants were found to have significant improvement in high-density lipoprotein (HDL) cholesterol (p = 0.001), day spent on vigorous physical activity (p = 0.007), self-care motivation (p = 0.001) and self-efficacy (p = 0.005). At 2-month, participants sustained some of the aforementioned positive outcomes include HDL cholesterol, self-care motivation and self-efficacy with other significant improvement reported in hypertension self-care behaviour (p = 0.002). However, a significant decrease in percentage skeletal muscle (p = 0.002) was found between post-1 week and post-2 month. No significant differences were found in other outcomes between baseline, post 1-week and post 2-month of HSME programme. CONCLUSIONS:  This short term HSME though had limited impact on participants’ blood pressure but was found to improve other clinical and psychosocial outcomes. Therefore, a well-structured educational programme should be in place to support hypertensive patient in sustaining daily self-care activities.
