目的用于儿童青少年超重和肥胖评价的方法很多,各种方法各有优缺点,尚未形成一种统一的评价方法,由此造成不同地区儿童青少年肥胖及超重发病率缺乏可比性.近年来, WHO肥胖工作组的专家建议在儿童肥胖的常规评价中应采用体质指数 (BMI)的年龄别百分位数.但是到目前为止,中国还没有 BMI的年龄别百分位数报道.本文提供了陕西省 0- 18岁儿童的 BMI的年龄别百分位数曲线.方法采用 LMS法拟合曲线;所有分析均采用由 TJ Cole教授提供的 LMS法的特殊软件,分性别和地区进行分析.结果 BMI中位数曲线由生命早期的 12.70 kg/m2迅速增加, 8个月达高峰,为 17.02 kg/m2,然后下降,达 6岁左右的 14.61 kg/m2最低点后平稳变化.城市儿童脂肪重聚比乡村儿童早 2年,男生比女生早 1年,脂肪重聚后,女生的 BMI增加比男生快,城市儿童的增加比乡村儿童的快,随着青春期的开始,女生 BMI逐渐大于男生,乡村男女生之间的差别大于城市的.陕西省儿童青少年超重百分位数所在曲线男女生分别为 P95.3和 P94.5,肥胖所在百分位数曲线男女生分别为 P99.5和 P99.8,明显低于欧美等发达国家的标准.结论通过 LMS法,建立了陕西省儿童青少年 BMI的年龄别百分位数曲线,百分位数曲线、超重与肥胖的界值可用于陕西省 0- 18岁儿童青少年营养状况的评价,不同性别、地区间的差别可帮助理解肥胖的原因及预防.

Aim There are several method for obesity and overweight assessment in child and adolescent, because these method are all have their own merits and defects, there is no one method can be used as a standard method in child obesity and overweight assessment, the detecting rate of obesity and overweight in different areas have no comparative. Recently, Expert on obesity work group of WHO recommended that age-related body mass index(BMI) be used rountinely to evaluate obesity in children. But up to now, no age-related reference curves for BMI have been reported in China. Presented here is the age-related BMI centile curves for children aged 0- 18 years in Shaanxi. Methods The LMS method was used for curve fitting; all analyses were carried out on the basis of different sexes and areas through a special program for LMS method which was devised by Cole TJ . Results Median BMI increased steeply in early life from 12.70 kg/m2, with a peak at 8 months of 17.02 kg/m2, then it declines, and then flattened out at about 6 years'14.61 kg/m2. The age at adiposity rebound for urban children was about 2 years earlier than that for rural children and 1 year earlier for boys than for girls, after adiposity rebound, BMI increased morn rapidly in girls than in boys, and urban children's increase was more rapidly than rural children's. As the puberty started, girl's BMI became higher than boy's, and the difference between boy's and girl's was larger for the rural children's than for the urban children's. For Shaanxi children, the overweight centile for boys and girls were P95.3 and P94.5respectively, P99.5 and P99.8 for obesity, Cut-off points for overweight and obesity was lower than that for international's. Conclusion By means of LMS method, we constructed age-related BMI centile curves for Shaanxi children aged 0- 18 years. Centile curves, cut off points of overweight and obesity can be used as a reference for assessing nutrition status of Shaanxi children aged 0- 18 years. The identified gender and areas differences may be serve as guides to the understanding of the cause and prevention of obesity.
