ABSTRACT
Resumo O objetivo da pesquisa foi analisar a percepção do peso corporal acima do ideal em adolescentes de Recife/PE e sua associação com o perfil antropométrico e estilo de vida. Trata-se de um estudo transversal com 2.480 escolares participantes do Estudo de Riscos Cardiovasculares em Adolescentes (Erica). O modelo conceitual também considerou variáveis demográficas e socioeconômicas. A percepção do peso foi analisada por meio da pergunta "Na sua opinião o seu peso atual é?", sendo as respostas: "abaixo do ideal", "ideal" e "acima do ideal". As associações foram identificadas por meio da regressão de Poisson. A média da idade foi de 14,7 anos (DP = 1,6), 53,7% eram do sexo feminino e 70,7% eram eutróficos, de acordo com o índice de massa corporal/idade (IMC/I). A percepção do peso foi respondida por 48,8% dos adolescentes. Desses, 36,8% e 63,2% se percebiam com baixo peso e peso acima do ideal, respectivamente. Após os ajustes, as variáveis associadas à percepção do peso acima do ideal foram: sexo feminino, idade entre 12 e 14 anos, escolaridade materna maior que oito anos, IMC/I de eutrofia e de excesso de peso, estágio pós-púbere e realização de café da manhã e refeição com os pais ocasionalmente. Portanto, variáveis demográficas, antropométricas e do estilo de vida se associaram à maior chance de percepção do peso corporal acima do ideal.
Abstract This study investigated the perception of above ideal body weight among adolescents in the city of Recife, Brazil, and its association with anthropometric profile and lifestyle. A cross-sectional study was conducted with a sample of 2480 adolescents from the "Study of Cardiovascular Risks in Adolescents." The conceptual model also assessed demographic and socioeconomic variables. Body weight perception was analyzed by asking the question: "In your opinion, your current body weight is … ?" Answers included: below ideal, ideal and above ideal body weight. Statistics were identified using Poisson Regression analysis. The mean age was 14.7 years (SD = 1.6), 53.7% were female, and 70.7% were eutrophic according to the body mass index/age (BMI/A). Perception of body weight was answered by 48.8% of the adolescents. 36.8% and 63.2% saw themselves as below and above their ideal weight, respectively. After adjustments, the variables associated with the perception of body weight above the ideal (outcome variable) were the female sex, age 12 to 14 years, mother's schooling > 8 years, BMI/A in the ideal range, being postpubescent, having breakfast and meals with parents occasionally. Demographic, anthropometric and lifestyle variables were more likely to be associated with body weight perception above the ideal.

Perception of body-weight status is an important determinant of weight-related behaviours and may affect the burden of weight disturbances as a public-health problem. No study has assessed self-perception of the weight status regarding body-fat distribution among health workers to date. The aim of this study was to evaluate the association of the perception of weight and health status among 542 women working at health centres of Tehran. We assessed their perceived body-weight and health status and measured waist- and hip-circumference, weight, and height to calculate waist-to-hip ratio (WHR) as a measure of fat distribution and body mass index (BMI, kg/m2). Women reported their sociodemographic information, and the perceived weight and health status were compared with their actual fatness status, defined based on WHR and BMI, to determine misperception of weight status. Multivariate logistic regression models were performed to assess the predictive effects of various sociodemographic factors and actual fatness on the perception of weight and health status. The results showed that more than 40% of women with normal BMI overestimated their body-weight status while only 15.8% of these women had central obesity. BMI was the most important variable associated with misperceived weight status as normal-weight women had significantly more misperception (OR 8.16, 95% CI 4.82-13.82) than overweight/obese women. WHR did not show any significant relationships with perceived weight status. In addition, perception of health status was not associated with actual fatness indices. It is concluded, BMI was the main predictor of the perception of weight status in female employees. The importance of using body-fat distribution in the perceptions of weight and health status should be emphasized.
