Proportion of Sample Meeting Criteria for Eating Pathology
	Age 14  (N = 5256)	Age 16  (N = 4420)	Age 14 or 16 (N = 5823)
Binge eating disorder (BED) or subthreshold BED	0.4%	1.6%	1.6%
Bulimia nervosa (BN) or subthreshold BN	1.4%	3.8%	4.0%
Anorexia nervosa	2.7%	1.9%	3.6%
Purging disorder	0.4%	1.4%	1.3%
Disordered eating	12.9%	28.0%	29.1%
All eating pathology (including disordered eating)	17.9%	36.6%	37.0%
All EDs (excluding disordered eating)	5.0%	8.6%	9.9%

Note. Rates of eating disorder symptoms and diagnoses obtained by data from the Youth Risk Behavior Surveillance System Questionnaire along with objective measures of weight and height. Parent-reported data also used to determine diagnosis of anorexia nervosa. Disordered eating was defined as individuals who reported symptoms of an eating disorder but less frequent eating disordered behaviors (i.e., binge eating, purging, excessive exercise, or fasting less than once per week). Subthreshold bulimia nervosa and subthreshold binge eating disorder were defined as meeting criteria for these disorders with the exception that episodes of binge eating occurred less frequently than once per week.
