672例学龄儿童血脂和血糖与单纯肥胖症的相关性调查

Epidemiological Survey of Blood Lipid and Glucose Level of Schoolchildren in Beijing Changchun Street

为了解6～12岁儿童血脂和血糖代谢的状况及其与单纯肥胖症的相关性,选择北京市长椿街地区在校小学生672名,均测定血清总胆固醇(TC)、三酰甘油(TG)、空腹血糖(FBG)、身高和体质量。应用SPSS软件包进行统计学处理。发现:672例6～12岁儿童的TC、TG和FBG浓度分别为(4.66±0.52)mmol/L、(1.97±0.22)mmol/L、(4.25±0.96)mmol/L。其中TC4.68～5.17mmol/L占30.3％,5.20～5.69mmol/L占21.9％,≥5.72mmol/L占17.3％;TG≥1.65mmol/L占10.0％;FBG≥6.05mmol/L占7.8％。男女学生的TG、TC、FBG比较无统计学差别。TC、TG、FBG与儿童的年龄呈正相关。超重和肥胖儿童的TG、TC平均水平显著高于正常儿童。TG、TC与FBG之间存在两两正相关的关系。提示:超重和肥胖者在学龄儿童期即可出现脂类代谢异常。

The survey was aimed to evaluate the level of total cholesterol (TC), triglyceride(TG), fasting blood glucose (FBG), and prevalence of dyslipidemia of schoolchildren in Beijing Changchun Street. Height, body weight, fasting blood glucose (FBG), total cholesterol (TC), triglyceride(TG) and Rohrer index of 672 (aged 6-12 years, 326 boys, 346 girls) schoolchildren were collected and analyzed. For all these children, mean TC was (4.66±0.52) mmol/L, mean TG was (1.97±0.22) mmol/L and mean FBG level was (4. 25±0. 96) mmol/L. According to the criteria of dylipidemia, there were 17.3% and 21.9% children, with TC≥5. 72 mmol/L and TC 5.20-5. 69 mmol/L respectively. Besides, there were 10.0% and 7.8% children with TG≥1.65 mmol/L and FBG>6.05 mmol/L. The overweighted and obese children had higher TC and TG levels than normal children. The result of this survey suggests that overweight and obesity may increase the prevalence of dyslipidemia in schoolchildren.
