Prevalence of Cardiovascular disease risk among Medical Students in South India

Abstract

Background: Cardiovascular diseases (CVDs) are global epidemic and contribute to double burden in developing countries. Individual’s dietary habits and risk behavior influence the onset and progression of CVDs. Medical students are future role models of the society and their knowledge, habits and behavior can influence their practice in prevention of CVDs in general population. Aims & Objectives: To assess the prevalence of common cardiovascular risk factors among a sample of medical students. Methods: A cross-sectional survey was conducted among the medical students of the four professional years.  An anonymous self-administered questionnaire was used to assess the prevalent cardiovascular risk factors, dietary habits and risk behavior among the medical students. Results: Family history of CVD, obesity and hypertension were highly prevalent among the medical students. Majority of them took <5 servings of fruit or vegetables per day (97.6%), ate junk foods (91.3%) and had long sedentary activity (47.6%). Taking red meat intake (OR 4.79), junk foods (Odds Ratio, OR 2.59), and snacking habit (OR 1.73) was observed more among male students; no physical activity or sports was significantly more in females. Logistic regression analysis showed that a family history of CVD was strongly associated with hypertension and obesity among medical students while exercise was protective against hypertension. Conclusion: The medical students had very poor compliance to recommended dietary intake and physical activity. Generating awareness, incorporating healthy habits and introducing structured educational programs into medical curriculum will help in changing lifestyle.
