12城市大学生测量体重与自评体重比较分析

目的分析大学生自评体重与测量体重分布及其一致性。方法采用多阶段分层整群抽样的方法，按年龄、性别、专业分层抽样，对12城市大学生开展问卷调查。结果共调查4402名大学生，男生2149人（48．8％），女生2253人（51．2％）。调查对象超重肥胖率为10．1％，低体重率19．6％，自评体重与测量体重的一致率为65．7％，其中，男生一致率为67．3％，女生一致率为63．8％，男生高于女生（X2=7．063，P=0．008），差异有统计学意义；体重偏轻组、正常组和超重肥胖组的一致率分别为54．9％、67．8％和71．7％。不同年级、不同专业大学生自评体重与测量体重的一致率差异无统计学意义。结论大学生自评体重存在偏差，应根据情况进行分类指导。

Comparative analysis on actual body weight and self-reported body weight among college students in 12 cities in China

Objective To analyze college students＇ self-reported weight and actual weight distribution and the consistency between them.

The concordant rate between self-report and actual BMI was 65.7%, which was 54.9% in underweight group, 67. 8% m normal weight group and 71.7% in overweight and obesity group, and it became higher with BMI increasing. The concordant rate in males was 67.3% and that in females was 63.8%, and the difference was statistically significant.
