城市0～7岁儿童单纯肥胖症流行病学研究

National epidemiological study on obesity of children aged 0～7 years in china 1996

目的了解我国０～７岁儿童单纯肥胖症流行情况及特征，并与１９８６年我国的调查资料作比较。方法身高别体重大于美国卫生统计中心／疾病控制中心参照人群的１０％～１９％为超重，２０％～２９％为轻度肥胖，３０％～４９％为中度肥胖，５０％为重度肥胖。共调查了１１个城市２０８５１３名儿童。结果总肥胖检出率为：男２．２％，女１．９％。总超重率男女均为４．２％；肥胖超重比男１．９，女２．１。从地区分布看，肥胖与超重的检出率为：北片、南片高，中片低。脂肪重聚年龄为５岁，脂肪重聚比前半年为：男２．９％，女３．５％，后半年为男１．７％，女２．４％。与１９８６年相比，１０年动态趋势为：肥胖检出率年增长值，男１０％，女８．７％；南片和中片高，北片低。结论（１）单纯肥胖症已成为学龄前儿童严重健康问题。（２）１９８６～１９９６年肥胖检出率年增长率处于失控的奇高速度。（３）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。（４）脂肪重聚比提示学龄前控制肥胖的两个重要时期为生后１岁和５岁。

Objective To study on obesity of children aged 0～7 years in 11 cities in 1996. Methods The sampling size was 208, 513. The children were divided into 9 groups: birth ,1mo , 6mo ,1yr, 2yr , 3yr, 4yr , 5yr , 6 7yr. Results The prevalence of overweight was 4.2% (M4.2%, F4.2%); and of obesity, 2.0%(M2.2% F1.9%). The obesity to overweight ratio (ORR) was 2.1%(M1.9%, F2 2%). The adiposity rebound age (ARA) was 5 years. The adiposity rebound ratio (ARR) was 3.2 for ARR1 (M2.9%, F.5%) and 2.0 for ARR2 (M1.7%, F2.4%) in obese children and 3.5 for ARR1 (M 3.5, F3.5 ) and 2.5 for ARR2 (M2.8, F2.8) in overweight children respectively. The secular trend of prevalence of childhood obesity during 1986 1996 showed that the prevalence of obesity increased annually at 9.1% (M10%, F8.7%). [WT5”HZ〗Conclusion The obesity has already been a severe health and social problem of preschool children in China. The increment of prevalence of obesity during 1986 1996 has been out of control. The earlier of ARA and the larger of OOR is an important risk factor of increasing of obesity. 1 year and 5 years after birth, predicted by ARR, are two critical periods of obesity control in preschool children in China.
