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。
Objective To explore the effects of different nutritional status on blood pressure, blood glucose and blood lipid in children in order to provide basis for primary and secondary students to carry out nutrition and health education. Methods A total of 933 healthy children aged 7-14 years were collected from rural Hebei Province. Height, weight and blood pressure were measured. Fasting blood glucose (FSG), total cholesterol (TC), triglyceride (TG) Lipoprotein cholesterol (HDL-C), calculated using Friedwald’s formula for low-density lipoprotein cholesterol (LDL-C). The survey population was divided into overweight and obesity group, normal body weight group and low body weight group by height standard weight method. The differences of blood glucose, blood pressure and blood lipid among children were compared. Results The children over 7 and 14 years old had overweight and obesity rate of 16.83%, but their gender and age did not change obviously. Compared with normal weight and low weight group, overweight and obesity children had obvious blood pressure, hyperglycemia and high TG HDL-C levels were significantly lower. In addition, the detection rate of abnormal blood pressure, TG and HDL-C in overweight and obesity children was significantly higher than that of normal weight and low weight group. Conclusion Overweight and obesity in childhood are closely related to blood pressure, blood sugar and dyslipidemia.
