RESUMO
Cardiovascular diseases [CVD] especially Ischemic Heart Diseases [IHD] are responsible for more than 40% of mortalities in the Islamic Republic of Iran: As is the case in the Western hemisphere. physica1lllactivity is the most prevalent CVDs risk factor. The aim of this research was to determine the association of the physical activity indices [work, sport and leisure, time indices], and body weight measures with the risk of developing IHD in Tehran, Islamic Republic of Iran, This case - control study was conducted during 2003 and 2004 in Tehran Heart Center and Tehran Shahid Rajaii hospital. A sample of 100 IHD patients [cases] and 100 healthy individuals served as control The controls we.re matched to the IHD patients by age [ +/- 5 years], sex, Information about Physical activity was recorded by means of the Beacke questionnaire. Some important risk factors including hypertension. hyperlipidemia. diabetes and Body Mass Index [BMI] were also recorded. All the data were statistically analyzed with the SPSS for Windows. All reported P values are based on two-sided and compared to a significance level of 5%. The patients had significantly lower indices for work sports and Leisure time Physical Activity [P <0,001]. Analysis of BMI showed that there was a significant association between obesity and the ask of developing IHD [P = 0.01]. There was a significant negative correlation between BMI and Leisure Time Physical Activity index: the higher the BMI, the lower the likelihood of participation in Leisure Time Physical Activity activities. After multivariate analysis. the Leisure Tune Physical Activity [LTPA] independently had a protective effect against developing IHD risk. also in the cases group. Obesity increased the risk of IHD nearly 4 times more 10 comparison with normal subjects. Physical activity has a beneficial effect on IHD risk developing and IHD related predisposing risk factors
