Objectives: The aim of the present study is to evaluate the incidence and prevalence of eating disorders in the population of Polish upper secondary school female students, while considering the type of school and living conditions.
Methods: The investigations of eating disorders were conducted between March and June 2017 and covered female students of the upper secondary schools of Szczecin. Selection for the survey was multistep. 1,750 questionnaires were included in the analysis. The study used a tool for screening for the occurrence of eating disorders - the Eating Attitudes Test (EAT-26).
Results: Lower scores were observed among higher grade students (EAT-26, EAT dieting) as well as those who did not receive pocket money (EAT dieting, EAT bulimia) (p < 0.05).
Conclusions: (1) Age has proved to be an important prognostic factor for eating disorders. The risk decreased as the age of the examined girls increased. (2) The risk of eating disorders was almost 21 times higher among first and second grade girls.
Keywords: EAT-26; adolescents; eating disorders.
