广州市457名在校学生肥胖和血脂紊乱状况分析

Statistical Analysis of Overweight/Obesity and Dyslipidemia in 457 Students in Guangzhou

目的分析广州市457名在校学生肥胖和血脂紊乱状况。方法随机抽取广州市区小学、初中、高中各一所学校的学生共457名,测量身高、体重、脂肪含量,采集静脉血测定总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、甘油三酯(TG),按照美国国家胆固醇教育计划(NCEP)推荐的儿童血脂异常诊断标准进行分析。中国学龄儿童青少年超重、肥胖筛查体重指数依据中国肥胖问题工作组推荐标准。结果该样本中31.1出现血脂紊乱,超重+肥胖率为36.3,肥胖率为15.8;血脂紊乱发生率在体型正常者中与超重或肥胖者中有显著性差异(P<0.05);TC和脂肪含量在男女性别之间总体均数差异有统计学意义(P<0.05);体重指数(BMI)除LDL-C外,与TG、TC、HDL-C相关系数差异有统计学意义(P<0.05)。结论此次调查结果显示,457名学生中,按照青少年肥胖分级,超重与肥胖率已达到Ⅲ级水平中的高度警戒水平。

Objective To explore the status of overweight/obesity and dyslipidemia in 457 students in Guangzhou. Methods A total of 457 students were recruited randomly from elementary school, junior high school, senior high school in Guangzhou. Various physical and biochemical parameters were measured. These included the height, body weight and fat content. Vein blood was collected for the measurement of TC, HDL-C, LDL-C and TG. Dyslipidemia was determined according to recommendation of dyslipidemia criterion of adolescents defined by NCEP. Overweight/obesity was defined according to the criterion recommended by the Working Group on Obesity Problem in China. Results Results showed that 31.1% were dyslipidemia, 36.3% were overweight/obesity and 15.8% were obesity. There was a significant difference in dyslipidemia between the normal and the overweight/obesity subjects （P〈0.05）. Both TC and fat contents in the male subjects are significantly different from the female subjects （P〈0.05）. With the exception of LDL-C, BMI was correlated with TG, TC, and HDL-C （P〈0.05）. Conclusion The situation of overweight/ obesity in students has reached an alarming level.
