ResumoContexto: A autopercepção e a satisfação com a imagem corporal são fatores preponderantes na auto-aceitação do adolescente e podem gerar atitudes inadequadas que prejudicam seu crescimento e desenvolvimento. Objetivo: Relacionar o estado nutricional com a percepção e a satisfação da imagem corporal que o adolescente tem de si próprio. Métodos: A informação do índice de massa corporal (IMC) foi obtida por dados antropométricos para classificar o estado nutricional. Utilizaram-se silhuetas padronizadas para avaliar a autopercepção da imagem corporal e um questionário de autopreenchimento para determinar a satisfação com a imagem corporal. Resultados: A maior parte da população estava em eutrofia, porém, muitas meninas não se percebiam dessa forma. Embora a grande maioria dos adolescentes em eutrofia, sobrepeso e obesidade tivesse uma percepção adequada de sua imagem, as meninas apresentaram uma tendência para superestimar e os meninos para subestimar sua condição de sobrepeso e obesidade. A insatisfação com a imagem corporal foi mais prevalente entre os adolescentes em sobrepeso e obesidade, com destaque para as meninas. Conclusão: Meninos tendem a aceitar a sua imagem corporal, mesmo que dentro de um estado nutricional inadequado, enquanto as meninas parecem mais preocupadas com sua imagem corporal, e talvez essa preocupação as incentive a se manterem em eutrofia.Palavras-chave: Adolescência, estado nutricional, imagem corporal. AbstractBackground: The self-perception of and the satisfaction with their body image are determinant factors for the self-acceptance of the adolescents, and may generate inadequate attitudes that impair their growth and development. Objective: To investigate the association between nutritional state in adolescents and the self-perception of the satisfaction with body image. Methods: We obtained body mass index (BMI) through anthropometric data in order to classify the nutritional state of the adolescents. We also used standardized silhouettes to evaluate their self-perception of their body image, and a self-completing questionnaire to determine their satisfaction with their body image. Results: Most of the population was eutrophic. The girls, however, did not regard themselves that way. Even
OBJECTIVE: To describe the percentile distribution of body mass index (BMI) in school adolescents, by gender and age, comparing them with international parameters. SUBJECTS AND METHODS: The study included 8,020 adolescents aged 10-15 years from 43 schools in the city of São Paulo, southeastern Brazil. BMI values of the study sample were distributed in percentiles and compared to international parameters (CDC, Must and cols. and Cole and cols.). RESULTS: Both male and female adolescents aged 10 to 14 years showed BMI cut-offs over the international parameters, especially in the P50-P85 percentile range. At the age of 15, the observed values were very similar to reference data; however, BMI values in the 95th percentile were much higher than international parameters. CONCLUSIONS: The study results show how important it is to use adequate BMI values for Brazilian adolescents aged 10-15 since international parameters may not reflect the actual nutritional status of this group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
