A Survey on Effects of Physical Activity Education Based on Trance- theoretical Model on Blood Pressure Control in Patients with High Blood Pressure

Introduction: The high prevalence of hypertension all over the world and serious side effects is a major health problem in all societies. To reduce these effects, control of blood pressure is very important. Regular physical activity is one of the most effective strategies to reduce the risk of some noncommunicable diseases such as cardiovascular. The present study aimed to determine the effect of training of physical activity based on Trans-theoretical Model for controlling blood pressure. Methods: In this semi-experimental study, 60 patients with high blood pressure were selected by sampling method and randomly divided into either control or interventional groups. The means of Data collection was multi-part questionnaire that was included demographic characteristics, stages of change questions and factors affecting the Trans-theoretical model and the International Physical Activity Questionnaire short form. Questionnaires completed for two groups and then educational intervention was done in the intervention group. After two months, questionnaires were completed for both groups again. Data were analyzed in SPSS and t-test and Chi-square were used according to the data distribution. Results: Statistical analysis didn't show a significant difference between the two groups before the education regarding their stages of change, Decisional balance, physical activity, blood pressure and processes of change (p<0.005). After education, average scores of all the above-mentioned variables increased meaningfully, in the interventional group. (p<0.005). Conclusion: Education and intervention based on Trance theoretical Model, results to physical activity behaviors promotion and reduce high blood pressure in hypertensive patients
