*3.1. Description of the Sample*

The mean age was 23.1 (+/−7.4) years. The characteristics of the sample are shown in Tables 2 and 3. *p*-values ≤ 0.05 are in bold in Tables 2 and 3. A description of the sample according to the type of ED is available in Supplementary Material (Table S1).

**%**: percentage; m: mean; sd: standard deviation; AN-BP: anorexia nervosa binge-eating/purging type; AN-R: anorexia nervosa restricting type; BED: binge eating disorder; BN: bulimia nervosa; ED: eating disorder; EDI: Eating Disorders Inventory; MROAS: Morgan–Russell Outcome Assessment Schedule; sd: standard deviation; YFAS: Yale Food Addiction Scale.

#### *3.2. Prevalence of Food Addiction*

Of the 195 patients included in the study, 163 displayed "FA" (83.6%) and 32 exhibited "No FA" at inclusion. There was no significant difference (*p* = 0.067) between the prevalence of FA in the total sample according to the version of YFAS used (1.0 or 2.0). The prevalence of FA according to ED diagnosis was 61.5% for AN-R, 87.9% for AN-BP, 97.6% for BN and 93.3% for BED diagnoses. FA prevalence was significantly different across ED diagnoses (*p* < 0.001). There was no significant difference between the prevalence of FA according to YFAS version for AN-R (*p* = 0.129) and AN-BP (*p* = 0.948). For BN and BED diagnoses, the number of patients was insufficient to conduct a comparison analysis. Regarding the presence of recurrent episodes of binge eating (at least once a week), patients (n = 114, 58.5%) with this characteristic (82 with BN diagnosis, 15 with BED diagnosis and 17 with AN-BP diagnosis) were significantly more likely to have FA (*p* < 0.001).
