Abstract:

To investigate the relationship between body mass index（BMI），waist circumference（WC），waist haunch ratio（WHR），waist height ratio（WHtR）and metabolic factors of Tibetan children in Sichuan province. Methods 　Totally 818 Tibetan children （aged from 10 to 17）in Songpan，Sichuan province with complete information were selected by stratified multi-stage cluster random sampling method in October，2007. The systolic blood pressure（SBP），diastolic blood pressure（DBP），serum concentration of cholesterol（TC）， triglycerides （TG），high-density lipoprotein cholesterol（HDL-C）and low-density lipoprotein cholesterol（LDL-C）were measured and the correlationships among them were analyzed. Results　The incidence of overweight and obesity in girls（12.78%）was much higher than that of boys（3.30%）.The level of blood pressure and blood lipid were of significant difference among the normal group and overweight/obesity group both in girls and in boys.Controlling for sex and age，there was a positive correlation between BMI，WC and SBP，DBP.Also，there was correlation between the blood lipid levels and obesity indicators. Conclusion　The levels of BMI，WC，WHR，WHtR，blood pressure and blood lipid of Tibetan children in Sichuan are variable in different sexes and age groups.Therefore， monitoring of the BMI，WC，WhR and WhtR plays an important role in controlling and maintaining the blood pressure and lipid.

摘要：

调查四川省藏族儿童青少年肥胖指标体重指数（BMI）、腰围（WC）、腰臀比（WHR）、腰围身高比（WhtR）与血压、血脂，并对其相关性进行分析。方法　采用多阶段、分层、整群随机抽样的方法，选取 2007年10月调查的四川省阿坝自治州松潘县藏族儿童青少年818名资料完整者进行数据分析。测量计算BMI、WC、WHR、WhtR，并分别检测收缩压（SBP）、舒张压（DBP）、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL-C）以及低密度脂蛋白（LDL-C）的血清浓度，并进行相关性分析。结果　女童超重肥胖率（12.78%）高于男童（3.30%），男童和女童超重肥胖组的血压、血脂与同性别BMI正常组相比差异有统计学意义。对血压、血脂与年龄、肥胖指标进行不同性别单因素相关性分析显示，男童和女童的BMI和WC均与SBP、DBP呈正相关。血脂四项与肥胖指标有不同程度的相关性。结论　四川省藏族儿童青少年的BMI、WC、WHR、WhtR和血压、血脂存在不同程度的性别、年龄差异，尤其体现在16～17岁年龄组。监测儿童青少年期的BMI、WC和WhtR对于血压和血脂的控制和维持具有重要意义。
