Predictors of Heart Disease Knowledge Among Older and Younger Asian Indian Adults

Coronary heart disease (CHD) has been estimated to be the leading cause of mortality in developing countries in 2010, particularly among Asian Indians. When compared to other populations globally, Asian Indians less than 40 years of age are at an increased risk of myocardial infarction. The objective of this study was to identify the predictors of knowledge of heart disease among younger and older Asian Indians adults. A cross-sectional survey was undertaken in Sydney Australia. One hundred and forty-four participants of Asian Indian descent who attended the health promotion stall at the Australia India Friendship Fair in Sydney participated in the study. All participants completed a self-administered questionnaire. The Primary outcome of the survey was knowledge of heart disease as measured by the 25 item Heart Disease Facts Questionnaire. All six modifiable risk factors for heart disease namely smoking, high blood pressure, diabetes, high cholesterol, physical inactivity and overweight were identified by 45.2 % of those aged below 40 and 53.5 % of those aged above 40 years of age respectively. For younger adults, only smoking status was significant and was an independently predictor of knowledge related to CHD (b = -10.6, p = 0.001, sr² = 0.16). For older adults, smoking status and duration of residence were significant predictors of knowledge related to CHD (b = -7.4, p = 0.000, sr² = 0.24; b = 0.13, p = 0.001, sr² = 0.069 respectively). Although suboptimal, there were no statistically significant differences in the level of knowledge among older and younger Asian Indians. Nevertheless, strategies to improve the knowledge of heart disease among this cohort are warranted.
