BackgroundackgroundPhysical 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.

OObjectivebjective

activity and related factors

MethodsethodsCross-sectional study (2st phase of TLGS*)

7285 Tehranian 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.

CALCULATIONSLeisure 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.

MMethods ethods ContinuedContinuedEach 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/wk less than 600*.

1 OR of insufficient physical activity for health compared with the reference group2 Adjusted for age

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.
