Abstract

Lack of perceived risk due to individual health beliefs leads people with an increased risk of coronary heart disease (CHD) to disregard self-care behaviors to prevent CHD. The purpose of this study was to investigate CHD prevention behaviors and factors predicting CHD prevention behaviors among persons with an increased risk of CHD. The study sample consisted of 348 persons with moderate or high risk of CHD according to CHD risk stratification criteria. The sample was recruited from  patients who received care at NCD clinic of health promoting district hospital in Muang district of Buriram province. The proportionate stratified random sampling method was used for recruitment. Data was collected from June to August 2017. Research instruments included general information form, perceived health status and health motivation questionnaire, and CHD prevention behavior questionnaire.  The reliability coefficients of perceived health status and CHD prevention behavior questionnaires were .89 and .79, respectively, and data collection was during June to August, 2017.  Data was analyzed using descriptive statistics and multiple regressions.             


Results showed that majority of the sample was 60 years and older and had the Body Mass Index (BMI) 56.8% over the normal range. The CHD prevention behaviors among this sample was at moderate level (  = 2.52, SD = .83). Factors that predicted CHD prevention behaviors among people with an increased risk of CHD included health motivation, perceived severity of CHD, and perceived barriers. All three factors significantly predicted 42% of CHD prevention behaviors (p < .01). In conclusion, this study suggested that CHD prevention behaviors should be promoted among this population. Emphasis should be made on strategies to improve health motivation to perform CHD prevention behaviors, increase perceived CHD severity, and reduce perceived barriers of CHD prevention behaviors.
