Summary:Objective: To determine whether attention deficit hyperactivity disorder (ADHD) pharmacological treatment of severely obese subjects with newly diagnosed ADHD would result in sustained weight loss. Design: Longitudinal clinical intervention study of the effects of ADHD medication on weight change over 466 days. Subjects: 78 subjects (6 male, 72 female, mean age 41.3 years, BMI 42.7 kg m-2) out of 242 consecutively referred severely obese, weight loss refractory individuals were diagnosed as having ADHD. Sixty-five subjects received treatment and 13 remained as controls. Methods: Standard screening tests identified subjects likely to have ADHD. A diagnosis was made in 78 subjects by semi-structured clinical interview. ADHD subjects were screened for comorbid conditions (binge eating disorder, mood disorder, sleep apnea, chronic pain, gastroesophageal reflux disease). Satisfactory resolution of symptoms of comorbid conditions was achieved prior to the introduction of pharmacotherapy for ADHD. Subjects not accepting, tolerating or remaining on ADHD medication served as controls. Weight was measured at sequential clinic visits after initiation of pharmacotherapy. Results: Comorbid conditions were found to be highly prevalent (sleep apnea 56.4%, binge eating disorder 65.4%, mood disorder 88.4%). After an average of 466 days (s.d.=260) of continuous ADHD pharmacotherapy, weight change in treated subjects was -12.36% of initial weight and in controls +2.78%, P
