Abstract

SOUTO, Daniella Fagundes et al. Risk behaviors related to eating disorders in adolescents and its association with dental erosion. Rev. odontol. UNESP [online]. 2017, vol.46, n.2, pp.66-71.  Epub Feb 20, 2017. ISSN 1807-2577.  https://doi.org/10.1590/1807-2577.05916.

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.
