Predictive Power of the trans-theoretical model of Physical Activity in Patients with Type-2 Diabetes

خلاصه انگلیسی

Sedentary lifestyle is one of the most important modifiable factors associated with diabetes. Nevertheless, the level of physical activity in diabetics is poor. This study aimed to determine the predictive power of the transtheoretical model (TTM) of physical activity behavior in patients with type-2 diabetes. This study was conducted on 393 type-2 diabetic patients in Khorramabad in 2013, in which the participants were selected by the convenience sampling method. The data were collected through a 5-part questionnaire, and were analyzed by the statistical software of SPSS-18 using Pearson’s correlation coef icients, chi-square test, t-test, ANOVA, and multiple regressions. In this study, most of the participants (48.9%, 192 patients) were in Precontemplation stage, and only 15% and 6.6% were in the Maintenance and Action stages respectively. The results showed that most of the illiterate subjects were in the Precontemplation and Contemplation stages, and most of those with college education were in the Action and Maintenance stages. The mean daily exercise was 11.9±20.6 minutes, the mean was zero in the Precontemplation and Contemplation groups, and it was significantly higher in the Maintenance group than that in the other groups. A significant negative relationship was found between the mean daily exercise and perceived benefits, and a significant positive relationship between the mean daily exercise and processes of change, self-ef icacy, and decisional balance. The mean daily exercise had a significant positive correlation with self-ef icacy. Multiple regression showed that 33.8% of the variance of the mean daily exercise can be explained and predicted by the TTM constructs.The theory of stages of change had a good predictive power of physical activity levels in diabetic patients. Therefore, considering the constructs of this theory, it is recommended that physical activity be promoted and related educations be provided in diabetic associations and health care centers.
