The Effects of Intervention Based on the Trans-Theoretical Model on Physical Activity and Metabolic Control of Diabetic Women
AbstractBackground: Prevention and treatment of diabetes have an economic burden for the society. Treatment of diabetes is accompanied by the willingness of the patients to control their diabetes. This study aimed to show the effects of intervention based on the transtheoretical model on physical activity and metabolic control of diabetic women. Methods: This was a randomized control trial study which conducted on 98 diabetics women (48: intervention and 50: control) in two health centers in Qazvin, Iran. Patients of each center were placed in intervention group and control group randomly. Data collection tool was a questionnaire, consisting of demographic characteristics, the determination of physical activity (GPAQ) and a questionnaire about TTM constructs in physical activity behavior. The HbA1c determined by blood test. Educational intervention design based on the results of the questionnaire and data analysis and then implemented to the intervention group. Data related to post-test collected three months after the end of the intervention and then measured the HbA1c level. Data analyzed using SPSS software version 19. Results: There was no a significant difference before intervention in demographic variables, the amount of physical activity, HbA1c and constructs model in both groups. There was a significant difference after intervention in the mean constructs model of intervention group than control group (P<0.05). Moreover, there was a significant difference in the mean physical activity of intervention group than control group. While there was no a significant difference in HbA1c level in both groups. Conclusion: Transtheoretical model-based intervention required more consideration in increasing physical activity in chronic diseases. The implementation of similar interventions with more sample size is a necessity in both genders.
