摘要
目的:分析我国成年职业人群身体活动水平与超重肥胖的关系,为制定肥胖的防控措施提供依据。方法:使用2002年全国营养与健康调查中21834人的数据,采用一年回顾性体力活动问卷收集身体活动信息。将身体活动水平(physical activity level,PAL)分:久坐少动;活动较少;活动充分;活动活跃四级。BMI≥24kg/m2为超重肥胖。控制年龄、性别、地区、家庭收入、吸烟、饮酒和膳食脂肪摄入量后,分析身体活动对超重肥胖的影响。结果:久坐少动、活动较少、活动充分和活动活跃者的超重肥胖粗率分别为36.9%、31.7%、29.2%和25.5%。控制其他因素后,随身体活动水平的增加,超重肥胖的危险性降低。与久坐少动者相比,活动较少者、活动充分者和活动活跃者发生超重肥胖的危险性分别降低了22%、19%和29%。高收入、饮酒和高脂肪饮食也是肥胖的独立危险因素。结论:身体活动水平是影响我国职业人群超重肥胖的独立危险因素,久坐少动的大城市高收入中年饮酒男性是超重肥胖的高危人群。
Objective： To analyze the effect of physical activity level on overweight and obesity among Chinese profeseionals for developing intervention and prevention strategies for obesity. Method： Data source was from＂China National Nutrition and Health Survey in 2002 ＂. Physical activity level （PAL） was classified to four groups （PAL 1.00-1.39： sedentary： 1.40-1.59： low active： 1.60-1.89： active： 1.90-2.50： very active）. The influence of physical activity on obesity was observed after adjusting the relative effects of age, sex, region, family economic level, smoking, drinking and dietary fat. Results： The crude prevalence of overweight and obesity was 36.9%, 31.7%, 29.2% and 25.5% in sedentary, low active, active and very active groups respectively. After adjusting other risk factors, the higher PAL, the lower was the relative risk of overweight and obesity. Compared to the sedentary group, the relative risk of overweight and obesity decreased 22%, 19% and 29% in the low active, active and very active groups respectively. High economic level, drinking and dietary fat intakes were also independent risk factors of overweight and obesity Conclusion： Physical activity level was an independent risk factor of overweight and obesity among professionals in China. The middle age males living in large cities with high income and drinking have higher risks of overweight and obesity.
