Effect of Education Based on Trans-Theoretical Model on Physical Activity of Reproductive Aged Women Referred to Health Centers in Zanjan

Despite the health benefits of physical activity, many people still adopt sedentary lifestyles. This study aimed to investigate the effect of education based on trans-theoretical model (TTM) on physical activity of women of reproductive age in Zanjan.

This was a quasi-experimental study. Using convenience sampling method, the sample size of 120 women was selected and randomly allocated to study groups. The data was collected using a short version of Physical Activity Change Algorithm Questionnaire and IPAQ (International Physical Activity Questionnair) before and 3 months after intervention. In addition to training sessions, the intervention 2 group was trained to use pedometer.

Before the intervention most of the women were in contemplation and preparation stages and 3 months after the intervention, women in intervention groups moved to action and maintenance stages (P < 0.001). There was significant difference in mean time of weekly walking and physical activity in three groups 3 months after the intervention (P < 0.001). These changes were more prominent in women who used pedometer.

The findings showed that education based on the trans-theoretical model was effective in promoting the physical activity. Using the pedometer along with education had effect on improvement of the physical activity.
