中学生肥胖状况2种标准评价比较

Comparison of Two Obesity Criteria Among Secondary School Students

目的应用2000年"身高标准体重"和2003年国际生命科学学会中国肥胖问题工作组(WGOC)制定的"中国学龄儿童青少年超重、肥胖筛查BMI值分类标准"比较长沙市各城区所辖中学的学生肥胖状况。方法通过对4021名11～19岁中学生问卷调查,并进行身高体重实测,分别用2000年"身高标准体重"法和WGOC标准筛选超重、肥胖,比较2种标准筛选出的肥胖学生特征。结果(1)用身高标准体重、WGOC标准筛选出的超重率分别为3.8%和12.0%,肥胖率分别为14.1%和6.6%;(2)不同年龄、不同性别学生中,用2种标准筛选出的肥胖率和超重率存在明显不一致性。结论两种评价标准的侧重点各有不同,2000年身高标准体重侧重于反映青少年的肥胖水平,而WGOC标准则更侧重于反映青少年的超重水平。WGOC标准有利于及时监测中学生的超重现象,可为卫生职能部门预防青少年肥胖工作及早敲响警钟。

Objective To estimate and compare the results of obesity status by using both the weight - for - height standard method in 2000 and the“Body Mass Index （BMI） Reference Norm for Screening Overweight and Obesity in Chinese Children and Adolescents” issued by WGOC in 2003. Methods By using the weight - for- height standard method and the reference standard of BMI made by WGOC, a cross- sectional assessment of overweight and obesity was carried out in 4,021 secondary school students who were between l 1 -- 19 years old. The characteristics of two groups of obesity students were compared with each other. Results By using the weight- for- height method and the BMI methed, the prevalence rates of overweight were 3.8 % and 12.0% and the prevalence rates of Obesity were 14.1% and 5.5% respectively. The preva- lence rates of overweight and obesity were significantly different from these two methods. Conclusion Weight - for - height standard in 2000 focuses on reflecting the status of obesity, while BMI criteria issued by WGOC in 2003 focus on reflect- ing the status of overweight. The results suggest that the BMI criteria issued by WGOC are more feasible in detecting adolescents overweight which provide an early alarming signal used in prevention of obesity.
