BACKGROUND: The purpose of the present study was to investigate physical activity by socioeconomic status (SES) and sex in an Iranian adult population. METHODS: In a cross-sectional study, ۶۶۲۲ adults, who participated in the Isfahan Healthy Heart program (IHHP) surveys in ۲۰۰۴ and ۲۰۰۵ and were living in urban areas, were studied. Daily leisure time, household, occupational, and transportation physical activity, and total physical activity were calculated and compared in ۳ socioeconomic status groups classified by the two-step cluster analysis procedure. RESULTS: Statistically significant variations were found in all physical activity levels, except transportation, by sex. Men were more active than women in all fields, except household physical activity. Leisure time physical activity of men and women were significantly higher in higher SES levels. There was an opposite correlation between SES and total physical activity in men. CONCLUSION: Considering the importance of physical activity as a component of a healthy lifestyle, differences among varying socioeconomic status and sex must be considered while planning for healthy lifestyle programs. Women with low SES, in particular, may need more attention.   Keywords: Physical Activity, Socioeconomic Status, Leisure Time, Gender, Cluster Analysis
