We wanted to assess the prevalence of individuals with food addiction (FA) among bariatric surgery (BS) patients at long term and to determine if there was any relationship between FA and both clinical and psychological outcomes at the time of the evaluation. Participants were evaluated for the presence of FA with the Yale Food Addiction Scale 2.0. Of 134 subjects, 32 (23.9%) included met criteria for FA. The frequency of patients with depression at the time of the evaluation was greater among subjects with FA (34.4% vs. 11.8%;  = 0.006). The score obtained with the Beck Depression Inventory at the time of the evaluation was greater among subjects with FA (14.8 ± 11.5 vs. 6 ± 6.5;  < 0.0001). The frequency of subjects with FA who had criteria for binge eating disorder at the time of the evaluation was significantly greater (56.3% vs. 20.5%;  < 0.001). Patients with FA scored higher in the Lattinen index for chronic pain at the time of the evaluation (8.7 ± 5.9 vs. 5.8 ± 5.4;  = 0.014). However, clinical outcomes were similar between the two groups. Routine screening for FA at long term postoperatively should be recommended to improve psychological outcomes of BS.
