| 目的 明确成都市儿童青少年静态生活方式现状及其与超重/肥胖的关系，探讨预防儿童青少年超重/肥胖的可能性。方法 采用整群随机抽样方法，抽取成都市2 211名7～15岁儿童青少年测量身高、体重等，同时使用自行设计的基础问卷和体力活动问卷进行调查，了解该人群基本情况及静态生活方式。结果 采用国际肥胖特别工作组（IOTF）标准，非超重、超重和肥胖组中男生周末看电视时间≥2 h/d报告率分别为34.80%、4.21%和1.92%（P=0.016 0），女生做家庭作业时间≥2 h/d报告率分别为12.17%、0.89%和0.49%（P=0.036 0）。采用中国肥胖问题工作组（WGOC）标准，在男生组得出相似结果；女生组三种静态生活方式（看电视、使用计算机及做家庭作业）在3个组中的差异均无统计学意义。分年龄组比较后发现，WGOC标准下13～15岁女生非超重组周末看电视时间≥2 h/d的报告率最高，其次为超重组和肥胖组（P=0.035 1）。以体力活动水平分组，采用Schofield标准，均表现为随体力活动水平的增加，男女生WHR有增加的趋势；采用中国营养学会（CNS）标准，只有男生组差异有统计学意义，且趋势不变。结论 成都市儿童青少年肥胖组静态生活方式报告率高于超重组和非超重组。但超重/肥胖与静态生活方式的关系还有待进一步研究。 |

| Objective To explore the situation of sedentary behavior and how it correlated to overweight/obesity among children and adolescents in Chengdu,China. Methods A total of 2 211 children and adolescents aged 7-15 years old were recruited in Chengdu city by using the cluster random sampling method. This was a cross-sectional study which aimed to collect data on anthropometry including height and weight and information on basic characters and sedentary behavior by using a self-designed questionnaire. Results According to IOTF criteria,the reporting rate of factor as ‘watching TV ≥2 hours per day on weekend' showed statistically significant differences among normal,overweight and obese groups (34.80%,4.21% and 1.92% respectively, P=0.016 0) in boys. The reporting rates of ‘doing homework ≥2 hours per day' were 12.17%,0.89% and 0.49% respectively (P=0.036 0) and statistically different among the three groups,in girls. Similar results were obtained in boys based on the WGOC criteria. However,there was no statistical difference seen on sedentary behaviors among the three groups in girls according to WGOC criteria. After stratified by age groups,rates on ‘watching TV on weekend' were statistically different among normal,overweight and obese group in 13-15 age group in girls (P=0.035 1). Physical activity level (PAL) was positively associated with WHR among both boys and girls when grouped according to PAL(Schofield).However,it was positively associated with WHR only seen in boys according to Chinese Nutrition Society (CNS) criteria. Conclusion The reporting rates of sedentary behavior in obese children were higher than that in overweight/normal ones. However,the correlation of sedentary behaviors on overweight/obesity called for further studies. |
