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.

Objective

To assess

leisure time physical activity and related factors

slide6
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.

calculations
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.
slide9
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*.

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 .

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.
