Stimulant dosage and age, race, and insurance type in a sample of children with attention-deficit/hyperactivity disorder

Research output: Contribution to journalArticle

Abstract

Objective: The aim of this study was to examine the association of age, race, insurance, and other factors with the prescription of stimulant medications. Methods: A retrospective chart review was conducted on 242 subjects, 4.8-19.8 years of age, treated in an urban referral center with a stable dose of stimulant medication for at least 6 months. Subjects were predominantly male (74.8%), African-American (52.9%), and insured by Medicaid (71.0%). The effects of age, race, insurance, gender, cognitive level, additional psychopharmacologic medications, and other factors on prescribed total daily dose (mg/day) and dose by weight (mg/kg/dose) were examined. Results: Race and insurance type together were associated with specific patterns of stimulant dosage, with higher dosing seen in Medicaid-insured non-African-American children and in privately insured African-American children. Total daily dose increased with age; however, there was an inverse relationship between age and dose by weight. There were no significant associations of gender, cognitive level, use of additional psychopharmacological medications, or other factors with total daily dose or dose by weight. Conclusions: The sociocultural factors of race and insurance type were related to dosing of stimulant medications in children. Total daily doses increased with age, while younger children were treated with higher weight-based doses. Attention to these factors should be given in the titration of stimulant medications in the treatment of ADHD. Other factors, including gender, had no specific association.
