Influence of a Trans-Theoretical Model Based Intervention on Physical Activity in Hypertensive Patients: A Randomised Clinical Trial
Asian Journal of Sports Medicine
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).
... ntrol). 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 postintervention 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.
