influence of a trans-theoretical model based intervention on physical activity in hypertensive patients: a randomised clinical trial

Background: although physical activity is necessary, but not performed by most hypertensive individuals. one of the most common theoretical frameworks used for understanding health behaviour change is the trans-theoretical model. objectives: this study was conducted to evaluate the effect of a trans-theoretical model based intervention on physical activity in hypertensive patients. methods: we conducted a randomized clinical trial among 60 hypertensive patients (31 experimental and 29 control). participants in experimental group received a fast walking intervention based on a trans-theoretical model. physical activity stages of change, processes of change, frequency, duration and intensity of walking were measured at the onset, 3 and 6 months post-intervention. the data was analyzed using spss 22 software. results: at 3 and 6 months post-intervention a significant difference was observed between the experimental and control groups for physical activity stages of change, processes of change, duration and intensity of walking (p < 0.05). also at 3 months post-intervention a significant difference was observed between the experimental and control groups for frequency of walking (p < 0.05). conclusions: this study suggests that trans-theoretical model based intervention in hypertensive patients play important roles in an individual’s commitment to participate in physical activity.
