Objective To study the determinants of exercise behavior among the overweight and obese residents, so as to provide reference for policy-making and health promotion in the future. Methods The study only enrolled overweight and obese residents to conduct a questionnaire survey and physical examination including height, weight and waist circumference. The self-designed questionnaire based on Health Belief Model had acceptable validity and reliability. Structural Equation Modeling was used to analyze the determinants of exercise behavior after univariate analysis and correlation analysis. Result Totally 2 489 overweight and obese residents(1 182 male and 1 307 female)were included in this study. Their average age was 45.3±14.2 years and their median amount of exercise was 4 thousand-step equivalent with quartile of (0.5, 10.0); 22.9% of these residents never took any exercise. Males with high school and equivalent level of education and an income of 5 000 to 10 000 yuan, took more exercise than other demographic groups. Amount of exercise had a positive correlation with perceived benefits of exercise, perceived severity of disadvantage of low exercise and self-efficacy, while it had a negative correlation with subjective barriers and objective barriers. Structural Equation Modeling showed that perceived subjective barriers, objective barriers and self-efficacy were determinants of exercise behavior. Their total standardized effects on exercise behavior were-0.085 (P=0.020),-0.242 (P<0.001) and 0.184 (P<0.001) respectively.Those with higher self-efficacy and less barriers preferred to do more exercise. Indirect effect widely existed in the SEM and self-efficacy were the most important mediating variables of all the other significant determinants. Conclusion The overweight and obese residents are seriously lack of exercise, which need some targeted intervention, especially by improving their self-efficacy and reducing their objective barriers.

Objective:To investigate the reasons of the tension of doctor-patient relationship and the medical violence from the perspective of the doctors, in order to provide a reference for finding a viable solution. Methods:Questionnaires survey were conducted about doctors' working conditions in 45 hospitals of 9 provinces. Results:On-ly 3. 6% medical staff had a harmonious doctor-patient relationship, the causes for the tense doctor-patient rela-tionship were poor communication with patients (75%), medical limitations (46. 2%);From the patients perspec-tive, the patients 'unpleasant caused by overtreatment due to complex illness accounted for 54. 2%;Institutional health-related reasons accounted for 82 . 6%. Conclusions:In the past five years after the new health care re-form, the tense doctor-patient relationship has not been released. So, should focus on training to enhance the com-munication skills of medical personnel and medical humanities education while the implementation of the national health care reform, in order to reduce iatrogenic conflicts.
