Abstract: Objective To investigate the actual weight, perceived weight among adolescents, and to analyze its relationship with self-esteem, thus to provide reference for the development of mental and physical health. Methods A total of 1 534 adolescents from two middle schools in Shandong province were randomly selected as participants.A self-designed general information questionnaire and Self-Esteem Scale (SES) were used to survey the adolescents, and their height and weight of the adolescents were also measured.Kappa test, t test, analysis of variance and multiple linear regression analysis were used for statistical analysis. Results The detection rates of wasting, overweight and obesity of adolescents in this study were 9.1%, 12.7%, and 10.1%, respectively.There was a lack of consistency between the actual weight status of adolescents and their perceived weight status (Kappa=0.325, P＜0.001).Only 19.4% of obese adolescents correctly assessed their weight status, which were lower than the other three groups (P<0.001).And 41.3% of adolescents misidentified their actual weight status.Boys, the only child, good family economic condition and perceived school performance had positive effect on the youth self-esteem level (P<0.01).The perceived weight of adolescents, rather than the actual weight, was closely related to self-esteem.Adolescents with perceived obesity had lower self-esteem (P<0.001). Conclusions There is a lack of consistency between adolescents' actual weight status and their perceived weight status.Adolescents' perceived weight, rather than actual weight, is closely related to self-esteem.Schools and parents should consider how adolescents perceive their own obesity to improve their self-esteem and help them grow healthily and happily.
