Abstract W MP3: Modifiable Risk Factors of Stroke and Psychosocial Health Factors Among Community-Residing Adults With Prehypertension
Introduction: Prehypertension that is systolic blood pressure (BP) over 120 mmHg or diastolic BP over 80 mmHg is known to be a predictor for the future development of hypertension and to be associated with increased risk for stroke. Although the impact of traditional risk factors such as hypercholesterolemia, overweight/obesity, lack of physical activity and high-fat diets on the development of hypertension and stroke has been delineated in people with prehypertension, recent research also suggests a need to examine further the relationship between psychosocial health factors such as stress, depression, and social engagement and BP.
Objectives: This study was undertaken to assess modifiable risk factors of stroke,social support and participation, and depression, and to explore the relationship between these factors and BP among community-residing adults with prehypertension.
Methods: A total of 178 participants aged 46.8 years old were recruited by a convenient sampling in two urban areas in South Korea. Trained interviewers interviewed participants with a structured questionnaire including demographic characteristics, lifestyle risk factors, stress, social support and participation, and depression. BP and anthropometric measurement and fasting blood sampling were performed to measure physiological risk factors. Data were analyzed using SPSS statistics 20.0.
Results: Mean systolic BP of participants was 131.04 mmHg and mean diastolic BP, 80.70 mmHg. Participants were over-weighted and only 28% of them did regular physical activity, showing mean Beck depression inventory scores of 29.61 which fell under the category of severe depression. After controlling for age and sex, stepwise multiple regression showed that BMI and depression were predictors of higher systolic BP and depression, a predictor of higher diastolic BP.
Conclusions: These results suggest the need to address psychosocial health factors, along with well- established risk factors such as BMI and physical activity, for BP management in community-residing prehypertensive adults. Further studies are warranted to fully understand and establish psychosocial factors and the mechanisms which contribute to BP elevation, and to develop interventions that decrease depression and BP.
