Background: Cardio Vascular Diseases (CVDs) are today the world__ampersandsignrsquo;s public health enemy No. 1. They are the world__ampersandsignrsquo;s leading killer diseases accounting 16.7 million deaths i.e. around 30% of total global deaths every year. Cardiovascular diseases (CVDs) are leading cause of death in developing countries including India. The huge burden of CVDs in Indian subcontinent is the consequence of the large population and high prevalence of cardiovascular risk factors. Objectives: To know the socio-demographic factors and magnitude of behavioral risk factors of Cardio vascular diseases (CVDs) among patients__ampersandsignrsquo; attenders of patients admitted in in-patient departments of Mc Gann hospital, Shimoga Methodology: Study Design: Questionnaire based cross-sectional study. Duration of study: April to June 2012 (3months). Participants: 200 patient attenders of in-patient departments of Mc Gann hospital, Shimoga. Statistical test: Chi square test. Materials and methods: A pre-designed and pretested questionnaire was used to collect the data regarding behavioral risk factors of CVDs Results: The total study population included 200. Age range was 18-65years. Proportion of major behavioral cardiovascular risk factors was: current smokers 56 (28%), chewing tobacco 57 (28.5%), alcohol intake 82 (41%), and over all sedentariness 95 (47.5%). Conclusion and recommendation: The study results indicated high proportion of behavioral risk factors among study subjects. Because of this high level of risk factors they are at increased risk of being cardio vascular diseases victims. We recommend health education for health promotion and immediate and effective implementation of national programs for prevention and control of CVDs.
