背景:生长图是评估儿童健康的重要方法,增长,和营养状况。使用生长图监测儿童和青少年的生长至关重要。
目的:提供反映山西儿童成长的体重指数(BMI)-年龄参考。我们还将我们的新数据与中国其他城市的增长参考和世界卫生组织(WHO)的增长标准进行了比较。
方法:采用分层整群随机抽样方法招募5461名6~17岁儿童青少年。测量身高和体重并计算BMI。采用LMS法按性别、年龄计算体重指数百分位值。显示了男女两性的BMI-年龄增长曲线,并与中国其他城市和世卫组织的参考数据进行了比较。
结果:BMI百分位数随年龄增长而增加,但男孩和女孩的模式不同。从3号到50号的百分位曲线略有增加,而从11岁到17岁的男孩和从6岁到14岁的女孩在较高的百分位数急剧增加。与中国其他城市相比,第50百分位数的值高于中国2009年、上海、长沙和中国2010年两性。与世卫组织的增长参考文献相比,中国女孩和男孩在所有百分位数上都有更高的值,而女孩的曲线看起来大致相同。山西男孩的BMI中位数从6岁线性增加到17岁。
结论:山西6-17岁儿童的BMI百分位数与中国其他城市和世卫组织的生长参考曲线有显著差异。建议为当地儿童和青少年提供BMI参考曲线,以评估其生长发育并监测其营养状况。早期发现儿童超重和肥胖,为预防和控制儿童超重和肥胖提供科学依据。
BACKGROUND: Growth charts are an important method for evaluating a child\'s health, growth, and nutritional status. It is essential to monitor the growth of children and adolescents using growth charts.
OBJECTIVE: To present body mass index (BMI)-for-age references reflecting children\'s growth in Shanxi. We also compare our new data with growth references of other cities of
China and World Health Organization (WHO) growth standards.
METHODS: A stratified cluster random sampling method was used to recruit 5461 children and adolescents aged 6-17 years. Height and weight were measured and BMI was calculated. The LMS method was used to calculate the percentile values of body mass index by sex and age. Smoothed BMI-for-age growth curves were presented for both sexes and compared with reference data from other cities of
China and WHO.
RESULTS: BMI centiles increased with age but with different patterns in both boys and girls. The centile curves from the 3rd to the 50th had a slight increase, while a sharp increase was seen from 11 to 17 years in boys and from 6 to 14 years in girls in the higher centiles. In comparison with other cities of
China, the values for the 50th percentile are higher than those reported for children from
China 2009, Shanghai, Changsha and
China 2010 in both sexes. In comparison with WHO growth references, Chinese girls and boys had higher values in all percentiles, whereas curves of girls look roughly the same. The medians for BMI in Shanxi increase linearly from 6 to 17 years in boys.
CONCLUSIONS: The BMI percentiles of children aged 6-17 years in Shanxi differed significantly from the growth reference curves of other cities of
China and WHO. Recommending the provision of BMI reference curves for local children and adolescents to assess their growth and development and monitor their nutritional status. Early detection of overweight and obesity in children provides a scientific basis for the prevention and control of overweight and obesity in children.
