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

Abstract

Background: 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. Methods: 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. Results: 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. Conclusion: 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.
