摘要: 目的 探明久坐时间(ST)、体力活动(PA)与儿童超重肥胖的联合关系,为从身体活动角度制定儿童超重肥胖的防控策略提供依据。方法 本研究采用分层整群随机抽样方法,于2017年3-6月共抽取3 936名广州市7~12岁儿童。采用信效度良好的问卷评估儿童的ST和PA水平,儿童超重肥胖依据中国肥胖工作组制定的标准进行判定。每天进行课后ST≥2 h/d视为高ST,每天参加中高等强度PA≥60 min/d视为高PA;高、低ST和PA两两交叉分组后形成四组别。结果 广州市7~12岁儿童总体的超重肥胖率为21.5%。低ST高PA、低ST低PA、高ST高PA、高ST低PA四组别儿童的超重肥胖率分别为18.9%,17.8%,23.1%和22.3%。在控制了混杂因素后,与低ST高PA组儿童相比较,高ST高PA组儿童的超重肥胖风险是其1.286倍(95%CI:1.078~1.724),高ST低PA组儿童的超重肥胖风险是其1.219倍(95%CI:1.059~1.641)。结论 ST、PA与儿童超重肥胖间存在联合关系,有关部门从身体活动角度防控儿童超重肥胖时,除了考虑增加儿童中高等强度PA水平,也应多关注减少课后ST。

Abstract: Objective To explore the combined associations of after-school sedentary time(ST) and daily physical activity(PA) with children's overweight and obesity, so as to provide basis for formulating prevention and control strategies for children's overweight and obesity from the perspective of PA patterns. Methods Using stratified cluster random sampling method, 3 936 children aged 7 to 12 years in Guangzhou were recruited from March to June 2017. Children's PA and ST were assessed using a reliable and valid questionnaire. Overweight and obesity were determined according to the standards established by the Working Group on Obesity in China. After-school ST ≥2 h/d was regarded as high ST, and daily participation in moderate to high-intensity PA ≥60 min/d was regarded as high PA. Participants were finally cross-classified into four groups. Results The overall overweight and obesity rate of children aged 7 to 12 in Guangzhou was 21.5%. The prevalence rates of overweight and obesity in low ST/high PA group, low ST/low PA group, high ST/high PA group and high ST/low PA group were 18.9%,17.8%,23.1% and 22.3%, respectively. Compared with children in the low ST/ high PA group, children in the high ST/high PA group(OR=1.286, 95%CI:1.078 - 1.724), and high ST/low PA group(OR=1.219, 95%CI:1.059 - 1.641) had a higher risk for overweight and obesity. Conclusion PA and ST have a combined association with children's overweight and obesity, suggesting that intervention efforts should focus on ST reduction in addition to promoting PA.
