摘　　要：目的分析北京市城区儿童体重指数(BMI)、体脂百分含量及腰围与血脂谱的关系。方法采用随机整群抽样法抽取852名北京市城区9～10岁学生,血脂使用自动生化分析仪进行测定。Fisher确切概率法,有序资料的趋势性检验及中位数回归等统计学方法,分析了其中847份有效样本。结果随BMI、体脂百分含量和腰围的增加,总三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)有升高的趋势,高密度脂蛋白胆固醇(HDL-C)有降低的趋势,组间差异均有统计学意义(P<0.01)。TG主要受腰围(t=6.86)、性别(t=3.96)、体脂百分含量(t=1.85)影响;TC受体脂百分含量(t=5.31)影响;LDL-C受腰围(t=4.65)、身高(t=-2.79)、体脂百分含量(t=2.77)影响;HDL-C主要受腰围(t=-12.24)、性别(t=-5.83)影响。结论随着肥胖程度的增加,儿童血脂水平上升,且腰围对血脂水平的预测能力最强。Objective To study the relations between anthropometric parameters[body mass index （BMI）, percent of body fat, waist circumference] and blood lipids of urban children in Beijing and to compare the ability of prediction effect of waist clrcumference,percent body fat and BMI on lipid profiles. Methods 852 children aged 9-10 were recruited with multi-stage sampling. Serum lipids of children were measured using automatic biochemical instrument. Fisher＇s exact test, trend test and median regression were used to analyze the data from 847 subjects with valid information. Results （1）With the rise of the BMI, percent body fat and waist circumference, total triglycerides（TG）, total cholesterol（TC）and low density lipoprotein choleasterol（LDL-C） showed increasing trends while high density lipoprotein choleasterol （HDL-C） had a decreasing trend（ P〈 0.01）. （2）TG was mainly influenced by waist circumference（ t= 6.86）, sex（ t= 3.96） and percent of body fat（ t = 1.85）; TC was influenced by percent of body fat（ t = 5.31）; LDL-C was influenced by waist circumference（t =4.65）, height（t= -2.79） and percent age of body fat（ t = 2.77） ; HDL-C was influenced by waist circumference （ t = - 12.24 ）, sex （ t = - 5.83 ）. Conclusion With the aggravation of children＇s fatness（BMI, WC and PBF）, serum lipids would increase and WC seemed to be the best predictor for lipids among BMI, WC and PBF.
