目的了解儿童青少年体型自我评价和体重指数（BMI）评价结果的一致性，分析体型与抑郁症状的关系。方法以2010年全国学生体质与健康调研安徽省池州市5555名9～18岁儿童青少年为研究对象，比较体型自我评价和BMI评价结果的一致性及其与抑郁症状的关系。结果男女生体型自我评价和BMI评价结果具有轻度一致性（Kappa=0．217，P=0．000；Kappa=0．203，P=0．000）。43．0％的男生和37．5％的女生错误估计了自己的体型，男女生体型低估率分别为35．9％和23．3％，高估率分别为7．1％和14．2％，差异有统计学意义（χ2=145．223，P=0．000）。logistic多因素回归分析结果显示，体型自我评价和体型错估均与抑郁症状存在统计学关联。与自我评价正常组比较，自我评价消瘦、超重和肥胖的抑郁症状检出率比值比分别为1．255（95％CI：1．066～1．478）、1．538（95％CI：1．275～1．856）和1．713（95％CI：1．035．2．834），体型高估和低估学生抑郁症状的风险分别是一致组的1．705倍（95％CI：1．382～2．105）和1．241倍（95％CI：1．059—1．454）。结论儿童青少年体型自我评价与BMI评价结果一致性轻微，体型错估是抑郁症状的危险因素。应开展以生活技能为核心的综合性干预措施，促进儿童青少年身心健康。

Objective To examine the association between self-assessed somatotypes and depression related symptoms. Methods The study sample included 5555 students aged 9 to 18 years who had attended the Physical Fitness and Health Surveillance of Chinese School Students （2010） in Chizhou city, Anhui province. Association between self-assessed somatotypes, body mass index （BMI） and depression symptom were examined. Results There was a slight consistency between self-assessed somatotypes and BMI in both boys and girls （Kappa=0.217, P=0.000; Kappa=0.203, P=0.000）. Significant difference in the prevalence of depression was found among weight misperception groups in both genders （ χ2= 145.223, P=0.000）. The prevalence of underestimation of somatotypes was significantly higher in boys than in girls, while the result was reversive on the prevalence of overestimation. Additionally,the prevalence of depression was higher in girls than in boys （X2=5.199, P= 0.023 ）. Through logistic regression, data showed that self-assessed somatotypes and miscalculated groups were significantly associated with depressive symptoms. Compared to the group that self- assessment as being normal, those students when self-assessed as being slim, overweight or obesity were more likely to be depressive,with odds ratio（ORs） as 1.255 （95%Ch 1.066-1.478）, 1.538（95%CI： 1.275-1.856） and 1.713 （95% Ch 1.035-2.834） , respectively. Overestimated and underestimated somatotypes appeared to be risk factors causing symptoms of depression （OR= 1.705,95%CI： 1.382- 2.105; OR=1.241,95%CI： 1.059-1.454）. Conclusion Slight consistency was found between selfassessed somatotypes and BMI, while the misjudged somatotypes were the risk factor related to depressive symptoms. It was suggested that life skills education should be carried out as preventive intervention approach, to improve the physical and mental health well-being of children and adolescents.
