Abstract 2205: Effects of a Stroke Awareness Promotion Intervention for Community Living Adults with Prehypertension in Korea.
Introduction : People with prehypertension that is systolic blood pressure (BP) over 120 mmHg or diastolic BP over 80 mmHg are known to be at increased risk for stroke compared to normotensive people. For primary prevention of stroke, community-level interventions that equip prehypertensive individuals with relevant knowledge and self-care strategies are of paramount importance, and may lead to substantial reduction in morbidity and economic burden due to stroke. This study assessed effectiveness of an educational intervention utilizing individualized risk assessment and highlighting importance of self-initiated lifestyle modifications on stroke awareness and compliance with self-BP monitoring and healthy lifestyle for stroke prevention.
Methods : This was a single blinded, randomized, pretest, posttest study with 47 participants (23 in the intervention group and 24 in the control group) recruited by a convenience sampling in community culture centers and churches in two urban areas. The intervention consisted of 3- weekly, 2-hour face to face educational sessions accompanied by an individualized counseling session on individual stroke risk assessment using Framingham stroke risk profile; and 2 booster sessions by telephone calls. The intervention aimed to improve participants' awareness about stroke and their own risk of stroke; and active involvement in self-care management of their own health as primary prevention of stroke. All participants completed pretest, 4 weeks and 12 weeks measurements after intervention including stroke awareness, self-BP monitoring and lifestyle modification of regular physical activity and low-fat diet. Data were analyzed using descriptive statistics, χ2test, two sample and paired t-test, and repeated measures ANOVA with PASW statistics 18.0.
Results : Mean age of experimental group participants was 46.5 (standard deviation (SD) 10) and of control group, participants, 48.3 (SD 18). Mean BPs in experimental and control groups were 123.8 (SD 12.1) and 125.7 (SD 13.1) mmHg, respectively. After the intervention, significant improvements were found in the experimental group for stroke awareness (p=.001), self-BP monitoring and record keeping (P < .001), and lifestyle modification of regular physical activity and low-fat diet (p =.017). Effects of stroke awareness and self- BP monitoring were sustained over time.
Conclusions : Results indicate effectiveness of a stroke prevention intervention to promote awareness of the key risk factors and their control for people with prehypertension on taking responsibility for their own self-care behavior on a daily basis. Further studies are warranted to refine and validate intervention strategies for sustained lifestyle modification.
