摘　　要：目的了解无锡市青少年体质量指数状况及减肥行为与体重认知错误之间的相关关系,为保障身心健康发展提供支持。方法在无锡市方便抽取4所中学的960名中学生进行问卷及身高、体重的测试,分析体重认知错误与减肥行为之间的关系。结果无锡市中学生体型消瘦的比例为6.77%,超重肥胖的比例为26.77%。中学生高估自身体重的报告率为29.58%,低估的报告率为33.33%,认知正确的报告率为37.08%。男生高估体重的报告率为18.01%,女生为41.53%,差异有统计学意义(χ~2=63.57,P<0.01);男生低估体重的报告率为45.08%,女生为21.19%,差异有统计学意义(χ~2=61.65,P<0.01)。Logistic回归分析显示,认为超重肥胖的中学生无论客观体重如何,与自认为体重正常的学生相比发生减肥行为的可能性高达109.75倍(P<0.01)。对自身体重高估的中学生比正确认知体重学生更容易发生减肥行为[OR值(OR值95%CI)=10.44(7.01~15.55),P<0.01],并且男生和女生存在同样的趋势。结论应对无锡市中学生的体重观进行干预和引导,以形成正确的体重观念,保障身心健康发展。Objective To understand the relationship between body mass index and weight loss behaviors with weight-related cognitive distortions among middle school students in Wuxi.Methods A total of 960middle school students from 4middle schools in Wuxi were randomly selected to complete a questionnaire survey.Height and weight was assessed to analyze the relationship between weight perception and weight loss behaviors.Results The proportion of students with skinny body shape was 6.77%, and the proportion of overweight and obesity was 26.77%.About 29.58%middle school students overestimated their weight and 33.33%underestimated.Specifically,18.01%of the boys and 41.53%of girls overestimated (Χ^2=63.57,P<0.01),while 45.08% of boys and 21.19%of girls underestimated their body.weight (Χ^2=61.65,P<0,01).Logistic regression analysis showed that the weight of obese and overweight middle school students was 109.75times risk for weight loss behaviors (P<0.01),regardless of ob- jeotive body weight,eompared,with students who properly estimate their body weight.For students with overestimated body weight were more likely to have weight loss behaviors than those with correct cognitive awareness [0R(95%CI)=10.442(7.011-15.552), P<0.01],the same trends were found in boys and girls.Conclusion It's necessary to intervene proper weight-related cognitive awareness among middle school students in Wuxi,ensuring healthy development of physical and mental health.
