Abstract

Abstract : Objectives: The aim of this study was to assess comorbidity patterns and functional impairment in children with and without attention deficit hyperactivity disorder (ADHD). Design: Hospital-based retrospective cross-sectional study; data collection occurred between 2016 and 2019. Settings and patients: A total of 8256 children and adolescents, 6–17 years of age, with suspected ADHD agreed to participate in this hospital-based cross-sectional study over a 4-year period in China. Comorbidities and social functions were assessed according to the scales Vanderbilt ADHD Diagnostic Parent Rating Scale and Weiss Functional Impairment Rating Scale-Parent Form, which were completed by the parents of the study participants. Results: Of the 8256 children, 5640 were diagnosed with ADHD. Other 2616 children who did not meet the ADHD diagnostic criteria were classified as the N-ADHD group . The proportion of comorbidities (47.4%) and functional impairments (84.5%) in the ADHD group were higher than the N-ADHD group (p≤0.001). The functional impairment scores in all of the six domains, including family, academic, life skills, self-concept, social activities and risky activities, were significantly higher in the ADHD group than the N-ADHD group (p≤0.001). The functional impairment in ADHD group with comorbidities was more severe than those without comorbidities (p≤0.001). Comorbidities and core symptoms both can affect the functions of children with ADHD. Logistics regression analysis indicated that in all of the six functional domains, the effect of comorbidities on functional impairment exceeded the effects of ADHD core symptoms. Conclusions: Comorbidities had the greatest influence on different areas of adaptive functioning in children with ADHD. Clinical management of children suspected to have ADHD should address multiple comorbidities and functional impairments assessment, as well as core symptom analysis.
