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.
本研究的目的是确定巴西南里奥格兰德州弗洛里亚诺波利斯市女性青少年中神经性厌食症症状（EAT+）的患病率以及对身体形象的不满情况。按社会地理区域和公立/私立学校分类对比例样本（1148名青少年）进行分层，随后按小学和中学进行分配。通过饮食态度测试确定EAT+，并通过身体形状问卷评估身体形象。EAT+和对身体形象不满的患病率分别为15.6%和18.8%。EAT+与年龄（10 - 13岁）（比值比=1.542；p = 0.046）、超重/肥胖（比值比=2.075；p < 0.001）、对身体形象不满（比值比=14.392；p < 0.001）以及公立学校（比值比=1.423；p = 0.041）相关。多元逻辑回归显示，对身体形象不满是神经性厌食症症状最强的独立危险因素（比值比=16.7；p < 0.001）。弗洛里亚诺波利斯市青少年的EAT+患病率与巴西其他地区观察到的患病率相似。
