4. Background • Physical inactivity represent an independent risk factor for a number of chronic diseases and obesity. • Six out of ten leading risk factors to all deaths in the world relate to diet and physical activity. • The World Health Organization (WHO) estimates that over 60% of adults are not active enough to benefit their health. • Results of the first survey of non communicable disease risk factor surveillance system of Iran in 2005 showed that 60.6% of males and 77% of females were inactive.

5. Objective To assess leisure time physical activity and related factors

6. Methods • Cross-sectional study (2stphase of TLGS*) • 7285Tehranian adults (3138 males and 4147 females) over the age of 20 years • Modifiable Activity Questionnaire (MAQ) • MAQ assesses past-year leisure activities • estimate the frequency and duration for each activity identified. *Trials 2009 Jan 25; 10:5.

8. CALCULATIONS • Leisure Activity Hours per week averaged over the past year • Occupational Activity • 1. Hours per week of moderate activity averaged over the past year • 2. Hours per week of hard activity averaged over the past year • 3. An estimate of the average hours per week above light activity during the past year: The summation of hours per week of moderate and hard activity • 4. Estimated metabolic cost (as MET-hours per week): the moderate and hard activity categories are multiplied by their estimated average group MET values of 4 and 7 METs, respectively, prior to summing.

9. Methods Continued • Each activity was also weighted by its relative intensity, referred to as a Metabolic Equivalent (MET ) • MET- min/wk was calculated as MET value multiplied by the duration of activity in minutes multiplied by the frequency of activity per week. • Active category was based on MET- min/wk equaling or exceeding 600 so inactive category was based on MET- min/wkless than 600*. * http://www.cdc.gov/nccdphp/sgr/pdf/sgrfull.pdf

10. Results • 30.2% (95% CI = 27.2- 33.1%) of the males and 30.3% (95% CI = 27.7- 32.8%) of the females were considered active .

14. Association betweeneducational levels, smoking status, BMI, hours worked and insufficient physical activity for health: Males Forward Stepwise Logistic Regression 1 OR of insufficient physical activity for health compared with the reference group 2 Adjusted for age

15. Conclusion • The findings of the present study showed that most of men and women did not reach the current physical activity recommendations (69.8%) that are necessary for promoting health and preventing diseases. • It seems that some related factors such as BMI, educational levels, smoking status and hours worked are related to low level of physical activity in Tehranian adults. • It is recommended that health policy should encourage the Tehranian adults to be more active.
