Bulimia nervosa: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

The cause of bulimia is unknown, but psychosocial factors may contribute to its development. These factors include family disturbance or conflict, sexual abuse, maladaptive learned behavior, struggle for control or self-identity, cultural overemphasis on physical appearance, and parental obesity. Bulimia nervosa is associated with depression, anxiety, phobias, and obsessive-compulsive disorder.

Eating disorders are most prevalent in affluent cultural groups and are essentially unknown in cultural groups where poverty and malnutrition are prevalent. In developing countries, almost no cases of eating disorders have been recognized.

Bulimia nervosa usually begins in adolescence or early adulthood and can occur simultaneously with anorexia nervosa. It affects nine women for every man. Nearly 2% of adult women meet the diagnostic criteria for bulimia nervosa; 5% to 15% have some symptoms of the disorder.

About prevalence and incidence statistics:

The term 'prevalence' of Bulimia nervosa usually refers to the estimated population of people who are managing Bulimia nervosa at any given time. The term 'incidence' of Bulimia nervosa refers to the annual diagnosis rate, or the number of new cases of Bulimia nervosa diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
