Risk behaviors related to eating disorders in adolescents and its association with dental erosion

Abstract Introduction The overvaluation of thinness as a standard of beauty has contributed to the development of eating disorders and has mainly affected adolescents and young adults. Objective To evaluate the prevalence of risk behaviors for eating disorders and their association with dental erosion in adolescents. Material and method This is a cross-sectional observational epidemiological study. The sample consisted of 278 adolescents aged 12 to 19 years, enrolled in a State School in Campinas - SP. Two questionnaires were used for the data collection on eating disorders: Bulimic Investigatory Test of Edinburgh and Eating Attitudes Test -26. The presence of erosion was evaluated by calibrated examiners. Result The mean age of the sample was 14.8 years. The prevalence of mean risk for bulimia in the sample was 43.2% (95% CI: 37.3%-49.0%) and the prevalence of adolescents with a probability of developing bulimia was 53.2% (95% CI: 47.4%-59.1%). Of the total, 11.9% (95% CI: 8.1%-15.7%) showed results suggestive of anorexia. Among women, 66.9% were classified as probability developing bulimia, whereas in men the prevalence was 39.0%. As for dental erosion, only 1.1% of the sample presented erosion. Conclusion The study pointed to large number of adolescents with risk behaviors for eating disorders but no association was found with dental erosion due to low prevalence.

摘要：将瘦削过度奉为美的标准，助长了进食障碍的发生，且此类障碍主要累及青少年与青年群体。
目的：本研究旨在评估青少年进食障碍风险行为的患病率，并分析其与牙齿酸蚀症的关联。
材料与方法：本研究为横断面观察性流行病学研究。研究样本纳入278名年龄12至19岁的青少年，均就读于巴西圣保罗州坎皮纳斯市的一所州立中学。研究采用两份问卷收集进食障碍相关数据：爱丁堡贪食症筛查问卷（Bulimic Investigatory Test of Edinburgh）与进食态度测验-26（Eating Attitudes Test -26）。牙齿酸蚀症的检出由经过校准的检查人员完成。
结果：本研究样本的平均年龄为14.8岁。样本中存在贪食症平均风险的受试者占比为43.2%（95%置信区间：37.3%~49.0%），具有贪食症发病风险的青少年占比为53.2%（95%置信区间：47.4%~59.1%）。总样本中11.9%（95%置信区间：8.1%~15.7%）的受试者结果提示存在神经性厌食症风险。女性群体中66.9%被归类为贪食症发病风险人群，而男性群体的该患病率为39.0%。关于牙齿酸蚀症，仅1.1%的样本出现酸蚀表现。
结论：本研究显示存在进食障碍风险行为的青少年比例较高，但由于牙齿酸蚀症患病率极低，未发现其与进食障碍风险行为存在关联。
