Objective:
Although clinical studies suggest that bulimia symptoms are common in youth, research on the prevalence of such symptoms and of their association with comorbid internalizing problems in the general population has been limited. This study aimed to evaluate the gender-specific prevalence of bulimia symptoms in Czech youth and explored the association between a clinical level of self-reported bulimia symptoms (CLBS) and internalizing problems by gender, controlling for age, socio-economic status and puberty status.
Method:
The study was conducted on a representative national sample of Czech youth (N = 4430, 57.0% female) using self-report scales. Multivariate analysis of covariance (MANCOVA) was used to examine the associations.
Results:
The 3-month CLBS prevalence was higher in girls (11.4%) than in boys (3.8%) and in both genders a CLBS was associated with higher levels of comorbid internalizing problems.
Discussion:
Timely recognition of bulimia symptoms and associated risk factors is important for early prevention and intervention strategies.
Level Of Evidence:
V, cross-sectional descriptive study (according to Oxford (UK) CEBM Levels of Evidence, 2011).
