超重和肥胖对儿童血压、血糖及血脂的影响

目的探讨儿童不同营养状况对血压、血糖及血脂的影响,以便为中小学生开展营养健康教育提供依据.方法在河北省农村整群抽取933名7～14岁健康儿童,测量身高、体重、血压,采集空腹静脉血测定血糖(FSG)、血清总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C),用Friedwald's公式计算低密度脂蛋白胆固醇(LDL-C).用身高标准体重法将调查人群分为超重肥胖组、体重正常组和体重偏低组,比较儿童血糖、血压、血脂各指标的差别.结果 7～14岁儿童超重和肥胖率为16.83%,随性别及年龄的变化不明显.与体重正常及偏低组相比,超重和肥胖组儿童具有明显的血压、血糖及TG偏高现象,且HDL-C水平明显较低.此外,超重和肥胖组儿童血压、TG及HDL-C异常的检出率也明显高于体重正常及偏低组.结论儿童时期超重及肥胖同血压、血糖及血脂异常关系密切.

The Effect of Overweight and Obesity on Blood Pressure, Fasting Serum Glucose and Serum Lipids of Children

Objective To explore the effect of different body fat levels on blood pressure, fasting serum glucose(FSG)and serum lipids, and to provide evidence for developing nutritional education.Methods Height, weight, blood pressure(BP)were measured of a cluster sampling of 933 rural children aged 7-14 years in Hebei province. Their FSG, TC, TG, HDL- C were also determined with the fasting blood samples. LDL- C was calculated based on Fried wald formula. The children were divided into three groups according to weight-for-height: overweight and obesity group, normal group, low weight group. The differences were compared in the levels of BP, FSG and serum lipids among three groups. Results The prevalence rate of overweight and obesity was 16.83% among children surveyed. There was no significant difference between different ages and sexes. Overweight and obesity group had higher BP, FSG and TG and lower HDL - C as compared with the other two groups. The prevalence of higher BP, higher TG and lower HDL - C in the overweight and obesity group was significantly higher than in the other groups. Conclusion Childhood overweight and obesity are correlated to higher BP, FSG and serum lipids
