          Abstract

          Objetivou-se identificar a prevalência de sintomas de anorexia nervosa e de insatisfação com a imagem corporal em adolescentes (sexo feminino) de Florianópolis, Santa Catarina, Brasil. A amostra foi proporcional, estratificada conforme rede escolar (pública/privada) e região sócio-geográfica, posteriormente distribuída no ensino fundamental e médio. Foram analisadas 1.148 adolescentes sorteadas aleatoriamente nos estratos. A presença de sintomas de anorexia nervosa (EAT+) foi identificada pelo Teste de Atitudes Alimentares e a avaliação da imagem corporal pelo Questionário de Imagem Corporal. As prevalências de EAT+ e insatisfação com a imagem corporal foram 15,6% e 18,8%. O EAT+ apresentou-se associado à faixa de 10-13 anos (OR = 1,542; p = 0,046); sobrepeso e obesidade (OR = 2,075; p < 0,001); insatisfação com a imagem corporal (OR = 14,392; p < 0,0001) e rede pública (OR = 1,423; p = 0,041). A regressão logística múltipla apontou a insatisfação com a imagem corporal como a variável independente de maior risco para a manifestação dos sintomas (OR = 16,7; p < 0,001). Pode-se concluir que as adolescentes em Florianópolis apresentam índices de EAT+ semelhantes àqueles observados em outras regiões brasileiras.

          The objective of this study was to identify the prevalence of symptoms of anorexia nervosa (EAT+) and dissatisfaction with body image among female adolescents in Florianópolis, Santa Catarina State, Brazil. The proportional sample (1,148 adolescents) was stratified according to position of schools in the socio-geographic regions and public/private school classification, and was subsequently distributed according to primary and secondary schools. EAT+ was identified through the Eating Attitudes Test and evaluation of body image through the Body Shape Questionnaire. Prevalence rates for EAT+ and dissatisfaction with body image were 15.6% and 18.8%, respectively. EAT+ was associated with age (10-13y) (OR = 1.542; p = 0.046); overweight/obesity (OR = 2.075; p < 0.001); dissatisfaction with body image (OR = 14.392; p < 0.001); and public schools (OR = 1.423; p = 0.041). Multiple logistic regression showed dissatisfaction with body image as the strongest independent risk factor for symptoms of anorexia nervosa (OR = 16.7; p < 0.001). Adolescents in Florianópolis show EAT+ rates similar to those observed in other regions of Brazil.

            Review of the prevalence and incidence of eating disorders.

            To review the literature on the incidence and prevalence of eating disorders. We searched Medline using several key terms relating to epidemiology and eating disorders and we checked the reference lists of the articles that we found. Special attention has been paid to methodologic problems affecting the selection of populations under study and the identification of cases. An average prevalence rate for anorexia nervosa of 0.3% was found for young females. The prevalence rates for bulimia nervosa were 1% and 0.1% for young women and young men, respectively. The estimated prevalence of binge eating disorder is at least 1%. The incidence of anorexia nervosa is 8 cases per 100,000 population per year and the incidence of bulimia nervosa is 12 cases per 100,000 population per year. The incidence of anorexia nervosa increased over the past century, until the 1970s. Only a minority of people who meet stringent diagnostic criteria for eating disorders are seen in mental health care. Copyright 2003 by Wiley Periodicals, Inc. Int J Eat Disord 34: 383-396, 2003.

              Eating behaviours and attitudes following prolonged exposure to television among ethnic Fijian adolescent girls

              There are no published studies evaluating the impact of introduction of television on disordered eating in media-naïve populations. To assess the impact of novel, prolonged exposure to television on disordered eating attitudes and behaviours among ethnic Fijian adolescent girls. A prospective, multi-wave cross-sectional design was used to compare two samples of Fijian schoolgirls before and after prolonged regional television exposure with a modified 26-item eating attitudes test, supplemented with a semi-structured interview to confirm self-reported symptoms. Narrative data from a subset of respondents from the exposed sample were analysed for content relating television exposure to body image concerns. Key indicators of disordered eating were significantly more prevalent following exposure. Narrative data revealed subjects' interest in weight loss as a means of modelling themselves after television characters. This naturalistic experiment suggests a negative impact of television upon disordered eating attitudes and behaviours in a media-naïve population.
