objective: to assess the reliability of the classification for nutritional status and height-for-age when using self-reported weight and height and its relationships with self-reported data of body image perception and satisfaction among adolescents. methods: in this retrospective study, 304 adolescents before they had measured their height and weight, they self-reported these measures, they were asked about their body shape perception and body image classification was obtained by using a body silhouette scale. it was also used specific tests to assess body satisfaction and food behavior. results: it was found full agreement between height-for-age classification using self-reported and measured height (k = 1.00) and an intermediate level of agreement between body mass index calculated with self-reported and measured data (k %26lt; 0.75). however, adolescents who perceived themselves as %26quot;skinny%26quot; underestimated their self-reported body mass index whereas those who perceived themselves as %26quot;fat%26quot; overestimated it. those who perceived themselves as fat in the silhouette scale underestimated their body mass index. gender was also a factor for unreliable answers, as females tended to underestimate their self-reported body mass index and males to overestimate it. conclusion: the adolescents adequately self-reported weight and height information. however, body shape perception and body image classification were factors affecting answer reliability.
