Leib S, Mann TG, Stein D, et al. - Among 84 adolescents, aged 13 to 19 years, with severe obesity who sought bariatric surgery at the Sheba Medical Centre in Israel during the years 2011-2017, researchers studied the prevalence of attention-deficit/hyperactivity disorder (ADHD) and related post-surgical weight loss. Medical records were used to compile anthropometric and clinical data. In addition, data on adolescents that ultimately underwent surgery (n = 45) were obtained. According to findings, ADHD incidence in adolescents undergoing bariatric surgery was 28.6%, far higher than that of Israel's general adolescent population. No significant differences were found in decreases of weight, BMI, BMI standard deviation scores and body fat percent between candidates with or without ADHD. Higher scores on the ADHD-Rating Scale at baseline were linked to greater excess weight loss in the subgroup that filled questionnaires.
