Introduction and aim: The purpose of this study was to evaluate patients with adolescent idiopathic scoliosis (AIS) to determine whether a low body mass index (BMI) influences surgery outcomes and satisfaction.Methods: There were 39 patients in this prospective 3-year cohort study. The BMI, Cobb angle, the Body Shape Questionnaire 14 (BSQ-14), the Scoliosis Research Society Questionnaire 22 (SRS-22) and eight satisfaction questions results were obtained. Having a BMI greater than or less than 18 kg/m2 was used as a determiner to allocate patients to groups. As a low BMI is related to the presence of a disturbance in body perception, patients were also dichotomized by using the BSQ-14.Results: All scales were worse in both slimmer patients and the group with a body perception disorder. The group with a BMI <18 kg/m2 obtained a total of 82.31 points in the SRS-22, and it was 93.45 points for the group with a BMI >18 kg/m2 (p = 0.001). In terms of satisfaction, the percentage of patients that would undergo surgery again was 30.8 vs 69.2 % (p = 0.054). Patients with an alteration of physical perception obtained a total SRS-22 of 82.90 points versus 96.10 points in the control group (p < 0.001). No differences in terms of the Cobb correction (p = 0.29) or the percentage of correction (p = 0.841) were found in any case.Conclusion: The alteration of physical perception and a low BMI negatively affect the outcomes in AIS surgery, regardless of the curve magnitude and the percentage of correction. Considerable care should be taken in recommending surgical correction to these patients.
