Comparison of Demographic Variables Across Eating Disorder Risk/Clinical Status Groups

Low risk for an eating disorder (LR; n = 1068) High risk for an eating disorder (HR; n = 955) Clinical/subclinical eating disorder (with the exception of anorexia nervosa) (ED; n = 379) Possible anorexia nervosa (pAN; n = 52) Significance Pairwise Comparisons
Age 22.64 (6.36) 23.04 (6.59) 23.44 (7.42) 21.29 (3.56) F(3,2446) = 2.56; p=.053 partial η2 = .003 --

pAN<LR, HR, ED

Note. LR = low risk for an ED; HR = high risk for an ED; ED = clinical/subclinical ED (with the exception of AN); pAN = possible anorexia nervosa. Pairwise comparisons listed were significant at least at p < .05.
