National epidemiological study on obesity children aged 0～18 years in Chongqing urban area.

【目的】调查重庆城区儿童期单纯性肥胖症的流行病学状况。【方法】按照整群抽样原则抽取重庆市3个城区的16 176名0-18岁儿童作为调查对象,测量其身高体重。【结果】总体检出率为：超重13.4%、肥胖8.3%,其中男童分别为13.5%、10.0%,女童分别为13.3%、6.6%。总体肥胖-超重比值为1.61,其中男童为1.35,女童为2.02。儿童脂肪重聚年龄为5岁。【结论】重庆城区的儿童期单纯性肥胖症日益增多,脂肪重聚年龄超前和肥胖-超重比过大是肥胖检出率上升的重要危险因素。5-8岁是控制肥胖的关键期。
