Prevalence of Eating Disorders and Disordered Eating

Prevalence of eating disorders and disordered eating in Ontario and Canada 2011. View Summary (PDF)

Anorexia nervosa (AN) and bulimia nervosa (BN) are serious psychiatric conditions recognized by the DSM-IV (APA, 2000). The prevalence of eating disorders in Ontario has been established in a large nonclinical community sample (Garfinkel et al., 1995; 1996). Drawing from a sample of 8,116 individuals under the age of 65 years, the lifetime prevalence of bulimia nervosa was found to be 1.1% for female subjects and 0.1% for male subjects (Garfinkel et al., 1995). The lifetime prevalence of anorexia nervosa was found to be 0.56% for females (Garfinkel et al., 1996) and 0.16 for males (Woodside, et al., 2001).

In addition to the full syndrome eating disorders, one in four adolescent females in Ontario (13-18 years) report engaging in at least one symptom of an eating disorder (Jones, Bennett, Olmsted, Lawson, & Rodin, 2001); and a significant amount of both male (25%) and female (30%) children, as young as 10-14 years, are dieting to lose weight, despite being within a healthy weight range (McVey, Pepler, Davis, Flett, & Abdolell, 2002; McVey, Tweed, & Blackmore, 2004; McVey, Tweed, & Blackmore, 2005).
