Desenvolvimento de uma escala de imagem corporal para mulheres brasileiras

Abstract

-Body image is an important parameter of body satisfaction and needs to be evaluated with instruments developed and validated for a specific population. The aim of this study was to develop and validate a scale to assess body image in Brazilian women. A scale consisting of 11 silhouettes was prepared. Content validation was performed by seven experts from different health areas. To assess repeatability (two consecutive assessments) and reproducibility (reassessment after one week), an intentional sample stratified into four groups according to the characterization of Brazilian women regarding nutritional status was selected. Participants were 125 women aged 18-55 years and body mass index (BMI) between 18.5 and 38.6 kg/m2. The Kappa coefficient (k) was used to assess repeatability and reproducibility, considering the isolated responses of the current body, ideal body and the difference between them, assumed as satisfactory when k≥0.6. For all trials, α=0.05. During the content validation phase, the instrument developed was changed following the evaluators' suggestions and it was considered very suitable by six of seven evaluators. The Kappa coefficient was good in isolated issues and in the difference between them in both repeatability and reproducibility. The Body Image Scale was considered a valid content, with good repeatability and reproducibility. Considering the instrument as low cost and of rapid implementation/evaluation, it may be used to evaluate the body image of Brazilian women with BMI between 18.5 and 38.6 kg/m2, in different contexts.

Pilates: efeitos na forca e imagem corporal de mulheres sedentárias

“…O peso e a estatura foram avaliados através de uma balança digital portátil com sensibilidade de 100 g (TechLine, São Paulo, São Paulo) e de uma fita métrica com sensibilidade de 1 mm (Sanny, São Bernardo do Campo, São Paulo). Para a avaliação da imagem corporal foi utilizada a Escala de Imagens Corporais (Souza et al, 2017), desenvolvido especificamente para mulheres brasileiras, um instrumento de baixo custo e rápida aplicação/avaliação. Para avaliar força, foram utilizados um dinamômetro palmar e um dinamômetro lombar.…”

“…O resultado numérico pode ainda ser positivo ou negativo, representando o desejo de ser maior ou o desejo de ser menor, respectivamente. No presente estudo foram extraídas duas informações: (1) figuração corporal, dada pela resposta da primeira questão que aborda a silhueta auto-referida como representativa do corpo atual e (2) a satisfação com a imagem corporal, atribuída à diferença entre o corpo apontado como o atual e o corpo autoreferido como ideal (Souza et al, 2017).…”
