摘要：Background: Considering the lack of data available on changes of physical activity over time in Iran, this study was designed to evaluate changes in physical activity levels among Iranian adults over a median 6.5 yr period.
Methods: In this population-based cohort study, 3515 participants, aged ³ 20 yr (2100 females and 1415 males) were followed from phase II (2002-2005) to phase IV (2008-2011) of the Tehran Lipid and Glucose Study. Information on physical activity, both leisure time (LTPA) and occupational (OCPA), was collected using the Modifiable Activity Questionnaire. Scores £ 600 METs-min/wk were considered as having low physical activity. Wilcoxon test was per-formed for comparing MET values between the two phases. McNemar test was used to evaluate differences between paired qualitative data.
Results: In both phases, 59.8% of adults were women, with mean±SD age 44.3±14.6 and 50.9±14.6 yr, in phases II and IV respectively. The prevalence of low physical activity decreased significantly in the follow up period (from 45.9% in phase II to 42.6% in phase IV, P=0.004). In both genders, a non-significant decrease in OCPA was ob-served, However, there was a significant decrease in LTPA among women (P=0.031), but not in men.
Conclusion: Despite the high levels of physical activity in Tehranian adults, a decreasing trend was observed. Significant decrease in LTPA among women indicates the urgent need to target women for prevention and implementation of pub-lic educational programs to promote physical activity levels and LTPA in particular, to compensate the reduction in OCPA.
