ABSTRACT

This paper estimates the prevalence of eating disorders (ED) in a sample of male and female adolescents of the Province of Málaga (Spain). The frequency of the subjects’ symptomatic behaviours is given. Information provided by the subjects themselves and by their parents is also taken into account. Method: Data collection took place during 1998 and 1999. The sample comprises 1,555 subjects (625 male and 930 female aged from 12 to 21 years) from 14 different public and private schools. The Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O’Halloran, Mulholland and Schneider, 1997) was anonymously completed by the participants. A new version of the Q-EDD was also given to the parents for obtaining more information from them about their children. The 50-question Q-EDD operacionalizes eating disorder criteria of the DSM-IV. Diagnoses are generated by a scoring manual that consists of flowchart decision rules. Subjects with ED are classified as anorexia nervosa (AN), bulimia nervosa (BN) and eating disorders not otherwise specified (EDNOS). Subjects without ED are classified as symptomatic (with some symptoms of the disorders being diagnosed) and asymptomatic (responding negatively to all eating disorder behaviours). Results: Most of the adolescents (69.1%) were classified as asymptomatic; 27.5% were symptomatic, although only 3.4% met all diagnostic criteria for ED. Females are four times more likely to have eating disorders than males (Odds Ratio=4.6). The pathology most frequently diagnosed was EDNOS (0.5% males, 3.9% females). The prevalence of AN was 0.5% in males and 0.4% in females. The prevalence of BN was 0.2% in males and 0.6% in females. These results are all comparable to those obtained in previous epidemiological studies, except for the prevalence of AN in males, which is higher in this work. These data suggest that ED, although predominantly a female complaint, is not exclusive of them. Further study on the possible increase of these disorders is justified, particularly on AN in the male population. Finally, the parents’ reports showed a lower frequency of ED than the adolescents’ self-reports.
