ABSTRACT
Objective: To explore the physical activity (PA) and regular exercise in adult residents of Beijing in order to provide the basis for guiding regular exercise and chronic disease prevention. Methods: A multi stage, random cluster investigation was conducted in 20242 residents from (18-79) years in Beijing area. Based on International physical activity questionnaire (IPAQ) published in USA (2000), the metabolic equivalent (MET) was calculated; according to the standard by General administration of sport of China, regular exercise rate was assessed. Weighting adjustment was conducted on the basis of 2010 Beijing population census data and sampling design. Results: 19584 participants with complete information were enrolled for final analyses. The median weekly MET of occupational PA, domesticity, transport-related PA and leisure exercise were (1918, 839, 922 and 928) MET-minute/week respectively. Female had the lower MET in occupational PA and leisure exercise than male (1436 vs 2156) MET-minute/week and (827 vs 944) MET-minute/week, both P<0.001. Elderly adults had the higher MET in leisure exercise than young and middle aged adults (1490 vs 718) MET-minute/week and (1490 vs 1162) MET-minute/week, both P<0.001. Regular exercise rate was only 31.5％ (95％ CI 30.7％-32.4％); multivariate analysis indicated that compared with male, female had the higher risk of insufficient regular exercise, OR=1.26 (95％ CI 1.14-1.40), compared with young adults, middle and elderly adults had the lower risk of insufficient regular exercise, OR=0.54 (95％ CI 0.50-0.59) and OR=0.46 (95％ CI 0.39-0.54). Compared to residents with education≤6 years, those with education at (7-12) years and with education>12 years had the lower risk of insufficient regular exercise, OR=0.66 (95％ CI 0.57-0.77) and OR=0.46 (95％ CI 0.39-0.54). Conclusion: Sampling residents in Beijing had insufficient leisure exercise with the low rate of regular exercise in 2011. Health policy and environment especially beneficial to female, youth and lower educated adults should be established to improve the healthy Beijing construction.
