恩平市城区学龄前儿童血脂状况分析

目的探讨恩平市城区超重、肥胖学龄前儿童血脂浓度的变化特点，为儿童肥胖的预防、治疗提供依据。方法选择恩平市城区6。7岁学龄前儿童1021名，测量其身高、体质量，并根据测量结果划分为正常体质量组，超重组和肥胖组。对自愿参加血脂浓度检测的494名儿童（正常体质量组127名，超重组219名和肥胖组148名）．采集空腹肘静脉血测定血清总胆固醇（total cholesterol，TG）、三酰甘油（triaeylglyeerol，TG）、高密度脂蛋白胆固醇（high density lipoprotein cholesferol，HDL-C）、低密度脂蛋白胆固醇（low density lipoprotein cholestorol，LDL—C）浓度。结果肥胖组血清HDL．C浓度低于超重组（1．37±0．27）mmol／Lvs（1．46±0．31）mmol／L，P〈0．05]和体质量正常组（1．37±0．27）mmol／Lvs（1．69±0．35）mmol／L，P〈0．05]；超重组血清HDL-C浓度低于体质量正常组，差异均有统计学意义（P〈0．05）。肥胖组血清TG及LDL—C浓度高于超重组（1．11±0．52）mmol／Lvs（0．87＋0．37）mmol／L，P〈0．05；（2．44±0．54）mmol／LVS．（2．17±0．51）mmol／L，P〈0．05]及正常体质量组（1．11±0．52）mmol／Lvs（0．71±0．25）mmol／L，P〈0．05；（2．44±0．54）mmol／L％（2．00±0．47）mmol／L，P〈0．05]；超重组血清TG及LDL．C浓度高于正常体质量组，差异有统计学意义（P〈0．05）。3组血清TC浓度比较，差异无统计学意义（P〉0．05）。结论恩平市城区学龄前儿童存在明显的血脂异常；应加强超重和肥胖儿童血脂检测，并进行综合干预。

Serum concentrations of lipids in preschoolers in Enping city

Objectives To explore the characteristics of serum concentrations of lipids in overweight and obese preschoolers,and provide evidence for prevention and cure of children obesity.Methods Height and weight of 1 021 preschoolers aged 6-7 years old in five kindergartens at Enping city in 2010 were measured.They were divided into normal-weight group,overweight group and obese children group according to the results of height and weight.Height,weight and serum concentrations of total cholesterol(TC),triacylglycerol(TG),high density lipoprotein cholesferol(HDL-C),low density lipoprotein cholestorol(LDL-C)of 494 volunteers of 1 021 preschoolers were measured,including 127 normal-weight,219 overweight and 148 obese children.Results Serum concentration of HDL-C in obese children group was significantly lower than those in overweight group (1.37±0.27) mmol/L vs.(1.46±0.31) mmol/L,P<0.05] and normal-weight group (1.37±0.27) mmol/L vs.(1.69±0.35) mmol/L,P<0.05],and it was significantly lower in overweight groupthan that in normal-weight group(P<0.05).Serum concentrations of TG and LDL-C were significantly higher than those in overweight group (1.11 ±0.52)mmol/L vs.(0.87±0.37) mmol/L,P<0.05;(2.44±0.54) mmol/L vs.(2.17±0.51)mmol/L,P<0.05] and normal-weight group (1.11±0.52) mmol/L vs.(0.71±0.25)mmol/L,P<0.05;(2.44±0.54) mmol/L vs.(2.00±0.47) mmol/L,P<0.05],and they were significantly higher in overweight group than those in normal-weight group(P<0.05).No significant difference showed in serum concentration of TG among the 3 groups(P>0.05).Conclusions Abnormal serum concentrations of lipids exist in preschoolers at Enping city.Measuring serum concentrations of lipids in overweight and obese children should be pay more attention to and these children should be generally treated.
