【摘要】：目的探讨中学生错误的体重认知与减肥行为的关系,为针对性的进行健康教育提供科学依据。方法抽取北京市西城区3所中学954名学生,比较中学生实测体质量指数(BMI)和自报体重之间的差异,采用Logistic回归分析低估体重和高估体重认知模式与减肥行为的关系。结果对自身体重认知错误的学生占62.1%(492/954)。男生倾向于低估体重(低估体重者占44.7%,高估体重者占17.5%),女生倾向于高估体重(低估体重者占20.7%,高估体重者占41.2%),男、女生对自身体重的认知差异有统计学意义(χ~2=20.907,P=0.002)。总体上,低估体重者采取减肥行为的可能性是体重认知正确者的0.265倍(95%CI=0.173~0.404),高估体重者采取减肥行为的可能性是体重认知正确者的10.439倍(95%CI=7.010~15.545)。男、女生均遵循此趋势,但女生减肥行为的产生比男生更依赖于主观判断。结论中学生对于自身体重的理性认知还存在较大的提升空间。应根据性别采取有针对性的健康教育以帮助学生形成正确的体重观,做出正确的健康决策,保持健康体重。
[Abstract]:Objective to explore the relationship between the wrong weight cognition and weight loss behavior of middle school students, and to provide a scientific basis for the targeted health education. Methods 954 students from 3 middle schools in Xicheng District, Beijing, were selected to compare the differences between the measured body mass index (BMI) and self reported weight of middle school students, and the Logistic regression analysis was used to underestimate weight and overestimate weight. The relationship between cognitive model and weight loss behavior was 62.1% (492/954). Boys tend to underestimate weight (underweight, 44.7%, overweight 17.5%), girls tend to overestimate weight (underweight 20.7%, overweight 41.2%), male and female students have different cognitive differences on body weight. The study significance (x ~2=20.907, P=0.002). Overall, the possibility of weight loss behavior was 0.265 times more likely to be weighed by the underweight people (95%CI=0.173~0.404), and the possibility of weight loss behavior was 10.439 times as high as those of the correct body weight cognition (95%CI=7.010~ 15.545). Men, girls all followed this trend, but girls' weight loss behavior It is more dependent on subjective judgment than male students. Conclusion there is still greater room for students to improve their rational cognition of their own weight. It is necessary to adopt targeted health education according to sex to help students form the correct concept of body weight, make correct health decisions, and maintain healthy body weight.
