Effectiveness of Educational Program based on Trans-Theoretical Model on Rate of Physical Activity among Household Women in Zahedan, Iran

According to the statistics of the World Health Organization (WHO) in 2003، sedentary lifestyle has led to 1. 9 million deaths worldwide. Despite many benefits of physical activity، more than 60% of adults worldwide and more than 80% of Iranian adults are inactive in terms of physical activities. Studies in Iran show that women’s health in this domain is at higher risk than men. Trans-theoretical model is a model that is known as a comprehensive model of sport. The aim of this study was to determine the effectiveness of education in physical activity among housewives in Zahedan، Iran. In this case-control study، 220 housewives (aged 19-52 years) living in apartments in Zahedan were studied (110 subjects in intervention group and 110 subjects in control group). Blocks sampling method was simple random sampling، then sequence number، the other blocks were sampled until sampling was completed. A multi-sectional questionnaire containing demographic characteristics، physical activity، stages of change and decisional balance were used. Its validity was determined by content validity and its reliability was determined by Cronbach''s alpha. This study indicated that before training، there was no significant difference between groups in terms of awareness، attitude and structures of trans-theoretical model. However، after the training، a significant increase was observed in the mean scores of awareness، attitudes، and model structures in the intervention group (P < 0. 001). According to the study، educational intervention on physical activity was effective. Corresponding institutions should include universities and other centers to develop and implement physical activity training programs.
