The purposes of this study were to examine the relationship between health belief model and sports participation frequency of patients with type 2 diabetes and to predict their sports participation frequency within the health belief model using multinomial logistic regression analysis. A purposive sampling method was used to recruit subjects from Type 2 diabetes at Pingtung, Taiwan. A total of 349 valid subjects were obtained. The collected data were analyzed with statistical procedure of Pearson Product-Moment Correlation and Multinomial logistic regression. The results showed that (1) A significant positive correlation was observed between perceived benefit of sport and sports participation frequency; A significant negative correlation was observed between perceived barriers of sport and sports participation frequency; (2) Perceived benefit of sport could significantly and positively predict sports participation frequency in patients with type 2 diabetes; perceived barriers of sport could significantly and negatively predict sports participation frequency in patients with type 2 diabetes. Based on the research findings, it was suggested that the hospital and health care providers can inform patients with type 2 diabetes with the importance and benefits of sports and the studies can explore sports time, sports intensity and other chronic disease in the future.
