目的了解西安市17年间儿童超重/肥胖的变化情况,为制定有效的干预措施提供理论依据。方法按照整群随机抽样方式,兼顾全市地理分布及经济状况,抽取了莲湖、未央和临潼3个区的0~7岁儿童10 374人,男5 498人,女4 876人。以WHO 2007身高别体重肥胖标准作为诊断超重和肥胖的指标,筛查出超重/肥胖儿童,并与1996年同年龄段儿童超重/肥胖率进行比较。对3岁及以上超重/肥胖儿童发放自行设计的0~7岁儿童饮食行为调查问卷。结果 1)2013年0~7岁儿童的超重率为16.87%,肥胖率为8.18%。2)2013年0~7岁男、女童超重率较1996年增加了约2倍,差异有高度统计学意义(χ~2=413.611,401.898,P<0.001)。2013年0~7岁儿童不同年龄段肥胖率的均显著高于1996年。3)超重/肥胖儿童食欲好,进食速度快,喜食甜饮料与肉食。结论 17年间西安市城区0~7岁儿童超重/肥胖显著增高,培养儿童良好的饮食行为习惯,制定儿童超重/肥胖的干预措施势在必行。
