Abstract Objective To study the clinical features and risk factors of co-morbid tic disorder(TD) in children with attention deficit hyperactivity disorder(ADHD). Methods A total of 312 children with ADHD were involved in this study. Subtypes of co-morbid TD, incidences of TD in different subtypes of ADHD(ADHD-I, ADHD-HI and ADHD-C) were observed. Thirteen potential factors influencing the comorbidity rate of TD in ADHD were evaluated by univariate analysis and multiple logistic regression analysis. Results Forty-two of 312 children with ADHD suffered from co-morbid TD(13.5%). Comorbidity rate of TD in children with ADHD-C(24.1%) was significantly higher than in those with ADHD-HI(10.9%) and ADHD-I(8.8%)(POR=7.000, POR=2.564,PConclusion The incidence of co-morbid TD in children with ADHD is influenced by many factors, and early interventions should be performed based on the main risk factors.
