Abstract
AIM: To examine how social factors might mitigate the elevated risk of mental health disorders in children with cerebral palsy (CP). METHOD: This cross-sectional study included 6- to 17-year-olds with (n=111; 40.4% 6-11y, 59.6% 12-17y) and without (n=29 909; 50.2% 6-11y, 49.8% 12-17y) CP from the 2016 National Survey of Children's Health. Mental health disorders included depression, anxiety, behavior/conduct problems, and attention-deficit/hyperactivity disorder. Social factors included participation in activities, bully victimization, and difficulty with friendships. RESULTS: After adjusting for sociodemographic factors and the presence of chronic pain, children with CP had higher odds of anxiety (odds ratio [OR] 4.4; 95% confidence interval [CI] 1.9-8.5), behavior/conduct problems (OR 3.9; 95% CI 1.4-11.3), and multimorbidity (OR 2.8; 95% CI 1.1-7.0), but not depression (OR 1.4; 95% CI 0.6-3.8) or attention-deficit/hyperactivity disorder (OR 1.7; 95% CI 0.6-4.6), compared to controls. With adjustment for participation in activities, the odds of anxiety, behavior/conduct problems, and multimorbidity remained increased in children with CP. With adjustment for difficulty with friendships, the odds of anxiety, behavior/conduct problems, and multimorbidity were no longer increased in children with CP. With adjustment for bully victimization, the odds of behavior/conduct problems and multimorbidity were attenuated in children with CP; however, the odds of anxiety remained increased. INTERPRETATION: The elevated prevalence of certain mental health disorders in children with CP is partly associated with modifiable social factors. WHAT THIS PAPER ADDS: Difficulty with friendships predicts an elevated prevalence of psychiatric conditions in children with cerebral palsy (CP). Bully victimization predicts an elevated prevalence of behavior/conduct problems in children with CP. Low participation does not predict mental health disorders in this population.
