Summary: | Purpose
Evaluate dietary habits and the presence of erosive tooth wear (ETW) among female adolescents with varying severity of bulimic symptomatology.
Methods
An explanatory study was conducted with 72 female school adolescents with bulimic symptomatology, aged 15–18 years in Southeastern Brazil. Dietary habits were evaluated through a food frequency questionnaire. Bulimic symptomatology was evaluated and classified (mild, moderate and severe) according to the Bulimic Investigatory Test of Edinburgh. ETW examinations were performed. Data analysis involved descriptive statistics, bivariate analysis, Kruskal–Wallis/Mann–Whitney tests and Poisson regression. Ethical approval and informed consents were obtained.
Results
The final population consisted of 62 participants. The prevalence of ETW differed among adolescents with mild, moderate and severe bulimic symptomatology (
p
= 0.001), corresponding to 5.9%, 8.0% and 45.0%, respectively. Adolescents with severe bulimic symptomatology presented higher daily consumption of acidic food: citric fruits (
p
< 0.005), diet soda (
p
< 0.009) and ketchup (
p
= 0.004). No difference related to vomiting practices was observed between groups (
p
= 0.060). The adjusted regression model showed that a higher prevalence of ETW was associated with self-induced vomit at least once a week (PR = 2.42, 95% CI = 1.00–5.86,
p
= 0.05) and higher frequencies of consumption of citric fruits (PR = 7.96, 95% CI = 1.50–42.11,
p
= 0.015) and diet soda (PR = 2.32, 95% CI = 1.09–4.91,
p
= 0.029).
Conclusion
It was the food choices (acidic food) and not purging practices that differed among adolescents with varying severity of bulimic symptomology. Likewise, higher consumption of citric fruits was the main factor associated with higher prevalence of ETW.
