1993-2009年7~18岁中国学龄儿童超重肥胖和腹型肥胖率变化趋势

【目的】 探讨1993-2009年7~18岁中国学龄儿童超重肥胖率和腹型肥胖率变化趋势。【方法】 选取1993、1997、2000、2004、2006和2009年“中国健康与营养调查”6次横断面调查数据,研究对象为7~18岁中国11 592名学龄儿童。研究内容包括性别、年龄、地区、身高、体重和腰围等。【结果】 7~18岁中国学龄儿童体质指数增加0.6 kg/m²(趋势P<0.001),腰围增加1 cm(趋势P<0.001);超重肥胖率从8.1%增加到18.0%(趋势P<0.001);腹型肥胖率从15.3%增加到28.9%(趋势P<0.001)。学龄儿童超重肥胖率及腹型肥胖率在不同性别、年龄及地区均显示出逐年增加的趋势(趋势P<0.001)。【结论】 17年来中国学龄儿童BMI、腰围、超重肥胖及腹型肥胖逐年增长,腹型肥胖的增加速度更为显著。因此,控制儿童肥胖迫在眉睫。

Trends in the prevalence of overweight and abdominal obesity among Chinese children aged 7~18 years from 1993 to 2009.

【Objective】 To examine the trends in body mass index(BMI),waist circumference(WC) and the prevalence of overweight(including obesity) and abdominal obesity among Chinese children aged 7~18 years from 1993-2009.【Methods】 Based on the data from the China Health and Nutrition Survey(CHNS) conducted from 1993 to 2009,a total of 11 592 Chinese children aged 7~18 years were included in the data analysis.The information includes gender,age,region,height,weight and waist circumference.【Results】 During the period of 1993-2009,mean BMI increased by 0.6 kg/m2(P for trend<0.001);mean WC increased by 1 cm(P for trend<0.001);the prevalence of overweight increased from 8.1% to 18.0%(P for trend<0.001);the prevalence of abdominal obesity increased from 15.3% to 28.9%(P for trend<0.001).The similar trends were found in nearly each group by gender,age and region(P for trend<0.001).【Conclusion】 The BMI,WC and the prevalence of overweight and abdominal obesity among Chinese children has increased greatly during the past 17 years,and abdominal obesity increased more greatly than overweight defined by BMI.
