Prevalence of eating disorder diagnostic and risk categories by gender.
| Total (N = 818) | Males (n = 348) | Females (n = 470) | Significance | |
|---|---|---|---|---|
| n (%) | n (%) | n (%) | χ2(df); p | |
| Eating disorder diagnostic and risk categories | ||||
| Low risk | 178(21.8) | 92 (26.3)a | 86 (18.4)b | 8.72 (2, 817); <0.05 |
| High risk | 161 (19.7) | 59 (17.1) | 102 (21.7) | |
| EDs | 479 (58.5) | 197 (56.6) | 282 (59.9) | |
| AN | 7 (0.8) | 0 | 7 (1.4) | |
| BN | 11 (1.4) | 5 (1.5) | 6 (1.3) | |
| BED | 1 (0.1) | 0 | 1 (0.2) | |

| ARFID | 39 (4.8) | 18 (5.2) | 21 (4.6) | |
Note. AN = Anorexia nervosa; BN = Bulimia nervosa; BED = Binge eating disorder; OSFED-BN = Other specified feeding or eating disorder bulimia nervosa (of low frequency and/or limited duration); OSFED-BED = Other specified feeding or eating disorder binge eating disorder (of low frequency and/or limited duration); OSFED-PD = Other specified feeding and eating disorder - purging disorder; OSFED - other = Other feeding or eating disorder - other; ARFID = Avoidant/restrictive food intake disorder. ED= All possible DSM-5 clinical/OSFED diagnosis groups.
Raked weights based on those assigned an ED category were applied to the analysis. Gender differences for ED diagnostic and risk categories was tested using a chi-square test. As some cells had 5 or less observations, we collapsed across ED diagnostic categories. The chi-square test is calculated on a 3 (low risk, high risk, ED) X 2 (men, women) table. Groups with different superscripts are significantly different from each other (p < .05).
