Promotion Of Physical Activity In Middle-aged Overweight And Obese People Based On Health Promotion Model

Middle-aged group is key to promoting social progress, but participation in physical activity of middle-aged people in China is not optimistic. How to promote more middle-aged people to participate in physical activity and reduce the incidence of overweight and obesity, has become a real and serious problem.With the health promotion model as the theoretical basis, this study focuses on how to effectively promote the participation in physical activity of overweight and obese middle-aged people, serving as a theoretical exploration. On the basis of previous studies, "Overweight and Obese Middle-aged People Physical Activity Scale" was developed, and the reliability and validity of the scale was tested. Using the revised scale, horizontal survey was carried out and Overweight and Obese Middle-aged People Physical Activity Model was developed through structural equation modeling. Based on the model, a 12-week intervention trial was carried out. People were divided into three groups: control group, health promotion model group and exercise prescription group. Then the physical activity and health of different groups are compared, in order to check the different effects of interventions. These are expected to provide references for the majority of health promotion workers.Results showed that:(1) After 12 weeks of intervention experiments, the levels of physical activity of prescription group and model group were significantly increased. That of the model group was higher than prescription group, showing the health promotion model-based intervention can significantly improve physical activity levels of middle-aged overweight and obese persons.(2) BMI values of the model group and prescription group decreased; the WHR, level index, reaction time tests of model group significantly changed; level index of prescription group significantly changed.(3) Physical activity levels of the three groups were tested after one month later from the end of the experiment, showing no statistically change. While two months later, physical activity levels of the model group and prescription group reduced, and the decline of prescription group was significantly higher than that of model group. All these showed that interventions differed in enhance effects and duration.Conclusion: "Overweight and Obese Middle-aged People Physical Activity Scale" compiled by this study has good reliability and validity, in line with physical measurement standards. Overweight and Obese Middle-aged People Physical Activity Model can effectively express relationships among impact factors and coupling effect between the factors. Effect of model based intervention is remarkable.
