[目的]分析小学生体质指数（BMI）与重要脂肪细胞因子的相关性.[方法]采用整群抽样方法抽取延边地区朝鲜族和汉族小学生3 879名作为研究对象,调查一般情况,测定BMI、血清脂联素（ADP）、脂肪细胞脂肪酸结合蛋白（A-FABP）、瘦素（LEP）及肿瘤坏死因子-α（TNF-α）水平.采用国际生命科学学会中国肥胖工作组（WGOC）制定的BMI标准评价学生的BMI分级.[结果]调整年龄、性别和民族的协方差分析结果显示,延边地区小学生LEP,TNF-α,A-FABP平均水平均随BMI水平增高而升高,差异均有统计学意义（FLEP=1 003.39,FTNF-α=14.55,FA-FABP=47.57,P〈0.001）;延边地区小学生ADP平均水平随BMI水平增高而降低,差异亦有统计学意义（FADP=66.27,P〈0.001）.Spearman相关分析结果显示,延边地区小学生BMI与LEP,TNF-α,A-FABP水平呈正相关（r值=0.428,0.130,0.197,P〈0.01）,与ADP水平呈负相关（r=-0.195,P〈0.01）.[结论]延边地区小学生BMI与不同脂肪细胞因子均密切相关,且BMI与不同脂肪细胞因子相关性程度有所不同.

英文摘要：

OBJECTIVE To analyze the correlation between BMI and important adipocytokines in elementary school students.METHODSA total of 3 879Korean-Chinese and Han nationality students was selected in elementary school of Yanbian area by cluster sampling,and it was measured that the general condition,body mass index（BMI,kg/m2）,adiponectin（ADP）,adipocyte fatty acid binding protein（A-FABP）,leptin（LEP）and tumor necrosis factor-α（TNF-α）levels.The levels of BMI were stratified by WGOC.RESULTSThe results of covariance analysis after adjustment of sex,race and age showed that the levels of LEP,TNF-αand A-FABP were progressively higher along with increasing the level of BMI（FLEP=1 003.39,FTNF-α=14.55 and FA-FABP=47.57;all P〈0.001）,and the level of ADP was progressively lower along with increasing the levels of BMI（FADP=66.27,P〈0.001）.Spearman correlate analysis showed that BMI was positively related with LEP,TNF-αand A-FABP（r=0.428,0.130 and 0.197;all P〈0.01）and was negatively related with adiponectin（r=-0.195,P〈0.01）.CONCLUSIONBMI in elementary school students of Yanbian area is closely related with different adipocytokines,and the correlative degree between BMI and different adipocytokines has some different.
