Abstract：Objective To analyze the influence of walking exercise on the changes of body composition and its influencing factors in occupational population, and to explore its effectiveness in prevention and control of chronic diseases. Methods The self-controlled method was used in this study. 95 adults were selected from government organs and public institutions in Donghu District of Nanchang City to participate in the 2015 Health Care Intervention Program called Walking Encouraged for Chinese Professionals, and the intervention based on walking aerobic exercise was conducted. Tsinghua Tongfang Body Tester (BCA-1C) and sphygmomanometer were used to perform physical examinations before the walking exercise and after 3- and 6-month walking exercise. The data of the three physical examinations were collected, and the health assessment questionnaire was simultaneously completed. SPSS 17.0 software was employed to make statistical analysis. Results The examination results of body composition before the walking exercise and after 3- and 6-month walking exercise indicated that the basal metabolism was increased (F=5.334, P<0.05), while body weight (F=8.921, P<0.001), waist circumference (F=8.883, P<0.001), fat content (F=5.193, P<0.05) and muscle mass (F=3.162, P<0.05) were all decreased, and the results of repeated measures analysis of variance showed statistically significant, but the variance in BMI (F=2.707, P>0.05) and hip circumference (F=0.731, P>0.05) was not statistically significant. Among the food intake, all the indicators were increased with rice (F=11.305, P<0.001), miscellaneous grains (F=7.724, P<0.001), meat (F=16.043, P<0.001), fish (F=10.194, P<0.001), eggs (F=7.055, P<0.001), dairy products (F=6.192, P<0.01), soybean (F=6.961, P<0.001), soy milk (F=10.495, P<0.001), vegetables (F=10.370, P<0.001) and fruits (F=10.377, P<0.001), and the results of repeated measures analysis of variance showed statistically significant. As for physical activity and sleep changes, heavy physical activity (F=7.759, P<0.001), moderate physical activity (F=4.258, P<0.05), light physical activity (F=6.566, P<0.05), meditation (F=3.442, P<0.05) and the sleep time (F=4.238, P<0.05) were all increased, and the results of repeated measures analysis of variance showed statistically significant. Conclusions Continuous walking exercise has significant effects on improvement of body composition (including basal metabolism, body weight, waist circumference, fat content and muscle mass), dietary structure and quality, and correct lifestyle (including heavy, medium and light intensity activities, meditation and sleep). It is an effective measure for prevention and control of chronic diseases.
