Lifestyle-related risk factors among patients with coronary artery disease in Nepal.

Abstract

Coronary artery disease (CAD) is the leading cause of death and morbidity globally. South Asia, including Nepal, has higher risks for CAD due to relatively higher exposures to risk factors. This study evaluated the prevalence of lifestyle-related risk factors and the associations of risk factors with socio-demographic variables among CAD patients. A cross-sectional study was conducted among CAD patients (n=224) admitted to a national heart centre in Nepal. Data on dietary habits, smoking, alcohol consumption, stress, physical activity, overweight or obesity and adherence to medication were collected using standard questionnaires. The numbers of risk factors were categorised into three groups (1-2=low, 3=medium, 4-7=high). Data analysis was performed by cross-tabulation and multinomial logistic regression. Prevalence odds ratios (POR) and their 95% confidence intervals (CIs) were used as the measure of the associations. The prevalence of risk factors among patients varied from 23% to 97%, with stress being the most prevalent, and current alcohol consumption the least. The majority of study patients had multiple lifestyle-related risk factors. Male patients (POR for medium vs. low 2.83; 95% CI 1.3, 6.18) and patients with high incomes (POR for high vs. low 2.53; 95% CI 1.10, 5.83) had higher odds of being in the medium- and high-risk group, respectively. Lifestyle-related risk factors were highly prevalent among CAD patients. Various socio-demographic variables were associated with the risk groups. Intervention studies on lifestyle risk factor modifications among this target group are recommended.
