Objective: Childhood psychiatric disorders affect current functioning and predispose individuals to more severe adult mental health problems. Provider survey research has suggested that children's mental health problems are increasing; observed changes may be due to increased illness or improved access to care. The authors sought to quantify trends in the prevalence of diagnosed and treated mental health conditions, outpatient treatment, and psychiatric medication prescriptions in a large population of children who were continuously insured.
Methods: The authors performed a retrospective trend study of diagnosed mental health conditions, treatment, and psychiatric medication prescriptions from 2003 to 2015 in children ages 2-18 who were military dependents (N=1,798,530). Poisson regression analyses and Cochran-Armitage tests determined trends in the prevalence of treated psychiatric diagnoses overall and by subcategory, rates of outpatient mental health visits, and psychiatric medication use overall and by specific class.
Results: From 2003 to 2015, the prevalence of children with diagnosed mental health conditions increased from 9.2% to 15.2% (rate ratio=1.04, 95% confidence interval=1.04-1.05, p<0.001). Identified suicidal ideation prevalence increased by 20% a year. Mental health care visits increased by 2% a year, and psychiatric medication prescriptions increased by 3% a year between 2003 and 2015, with larger increases seen among older children. Prescriptions for children with identified mental health conditions did not increase.
Conclusions: Diagnosed mental health conditions, pharmaceutical treatment, and outpatient visits all increased across a diverse U.S. pediatric population from 2003 to 2015. Results suggest that use of psychiatric medications kept pace with the increased number of diagnoses and that older children are most affected.
