Abstract

Objective: This study used Medicaid claims to compare the prevalence of mental health disorders (MHDs) and developmental disorders (DDs) between foster and nonfoster youth.

Methods: Medicaid claims data were used to identify MHDs and DDs. Diagnosis codes were categorized into 16 MHD and 8 DD groups. Children were enrolled in their respective Medicaid plan for at least 30 days and had at least 1 health care encounter generating a claim. Prevalence was compared between children in foster care and children not in foster care overall and by age group. Logistic regression was used to compare the odds of having an MHD or DD diagnosis.

Results: Of the 8706 children in foster care, 20.1% had an MHD compared with 9.7% of the 392,815 nonfoster children. Overall, the 5 most prevalent MHD and DD conditions among foster youth were attention-deficit/hyperactivity disorder (ADHD) (11.0%), miscellaneous (9.3%), bipolar disorders (5.6%), communication disorders (5.4%), and depressive disorders (5.1%). The 5 most prevalent conditions among children not in foster care were ADHD (6.1%); communication disorders (3.0%); disruptive, impulse control, and conduct disorders (2.7%); specific learning disorders (2.5%); and trauma and stressor-related disorders (2.4%). Anxiety was significantly higher among nonfoster children. The prevalence of the most common conditions by age group is reported. Overall, children in foster care had 2.5 and 2.3 times higher odds of having an MHD or DD diagnosis, respectively.

Conclusion: Children in foster care had significantly higher rates of mental health and DD diagnoses compared with children not in foster care.
