Prevalence and correlates of eating disorders among young adults in Finland.

BACKGROUND: This study investigated the epidemiology of eating disorders in a population-based sample of young adults.

METHOD: A mental health questionnaire was sent to a nationally representative two-stage cluster sample of 1863 Finns aged 20-35 years. All screen-positives and a random sample of screen-negatives were invited to participate in a Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) interview. Case records from all lifetime mental health treatments were also obtained and were used to complement the diagnostic assessment.

RESULTS: The lifetime prevalence of anorexia nervosa, bulimia nervosa, eating disorder not otherwise specified and any eating disorder among women were 2.1%, 2.3%, 2.0% and 6.0%, respectively, while there was only one man with an eating disorder. Unlike other mental disorders, they are associated with high education. Of women diagnosed with lifetime eating disorder, 67.9% had at least one comorbid Axis I psychiatric disorder, most commonly depressive disorder. While 79.3% of women with lifetime eating disorder had had a treatment contact, only one third of persons with current eating disorder had a current treatment contact. Women whose eating disorder had remitted still experienced more psychological distress and had lower psychosocial functioning that women without lifetime Axis I disorders.

CONCLUSION: Eating disorders are the fourth largest group of mental disorders among young women. They tend to be comorbid, often remain untreated and are associated with residual symptoms after the remission of eating disorder symptoms.
