ABSTRACT
To assess the physical activity level among MI patients and to examine the relationship of physical activity with some MI risk factors such as age, gender, body mass index [BMI], waist circumference [WC], obesity, and occupation. The data of the present study were collected from different cardiac hospitals [Civil Hospital, Liaquat National Hopsital and National Institute of Cardiovescular Diseases] of Karachi. 235 patients of ages 30-70 years were interviewed through a questionnaire. The questionnaire included basic demographic and some socio-economic information and risk factors associated with MI patients. The questionnaire also included questions on the type, frequency and duration of physical activity of the patients. Activities were classified into five intensity categories and assigned metabolic equivalents [MET] according to the compendium of physical activity. Subjects were classified into physically active or inactive categories. Activity prevalence [10.2%] was very low among MI patients. There were more active male patients [10.8%] than female patients [7.8%]. Activity prevalence decreases with age and increases with increasing educational level. In the risk assessment model, age group [P<0.0001], occupation categories [[skilled vs. semi skilled] [p=0.028]] and [[skilled vs. house wife] [p=0.003]] were significant. Highly educated patients were significantly [p=0.022] more active than others. Furthermore, active patients had lower values of body mass index and waist circumference. The finding of the study revealed that most of the MI patients have sedentary life style and due to increasing age and low level of education they are inactive
