摘　　要：目的分析中国3~17岁儿童体质指数(BMI)与体脂百分比(FMP)的关系。方法对中国0~18岁儿童营养与健康系统调查与应用项目中3~17岁儿童的BMI和FMP数据进行分析。采用BMI-Z评分/BMI和FMP分别对研究对象进行分类。采用Spearman相关分析BMI与FMP的相关性,采用Kappa检验分析BMI-Z评分/BMI和FMP对研究对象进行分类的一致性。结果10~13岁组男童营养不足、正常和超重/肥胖的FMP均高于其他年龄组(均P<0.001),女童各营养状况的FMP均随年龄增长而增加(均P<0.05)。男童各FMP水平组的BMI均随年龄增长而增加(均P<0.05);女童FMP为25%~、≥30%时,BMI随年龄增长而增加(均P<0.001)。BMI与FMP的相关性较强(r=0.705,P<0.001),其中男童r值为0.618,女童r值为0.884。BMI-Z评分/BMI和FMP对研究对象进行分类的一致性为中度(Kappa=0.574,P<0.001)。结论BMI与FMP的相关性较强,BMI-Z评分/BMI和FMP对研究对象进行分类的一致性为中度。Objective To analyze the relationship between body mass index(BMI)and fat mass percentage(FMP)in children aged 3-17 years in China.Methods The BMI and FMP data of children aged 3-17 years from the National Nutrition and Health Systematic Survey in 0-18 years old children in China was analyzed.BMI-Z score/BMI and FMP were used to classify the subjects,respectively.Spearman correlation was used to analyze the correlation between BMI and FMP.The consistency between BMI-Z score/BMI and FMP in classifying the subjects was measured using Kappa coefficient.Results The FMP of malnutrition,normal and overweight/obesity in boys was higher in age group 10-13-year than in other age groups(all P<0.001).The FMP of all nutritional status in girls increased with age(all P<0.05).The BMI of boys in all the FMP levels increased with age(all P<0.05).When the FMP of girls was 25%-or≥30%,BMI increased with age(all P<0.001).The relationship between BMI and FMP was strong(r=0.705,P<0.001),with r of 0.618 in boys and 0.884 in girls.The consistency between BMI-Z score/BMI and FMP in classifying the subjects was found to be moderate(Kappa=0.574,P<0.001).Conclusions There was a strong relationship between BMI and FMP.The consistency between BMI-Z score/BMI and FMP in classifying the subjects was moderate.
