Objective: To estimate prevalence and evaluate trends in obesity-related chronic medication use among children. Design, Setting, and Participants: Cross sectional study of ambulatory prescription claims from 2002 to 2005 for a sample of over 3.5 million commercially-insured children 5 to 19 years. Main Outcome Measures: Quarterly prevalence and trends in the prevalence of use for antihypertensives, type 2 antidiabetics, antidepressants, and statins. Results: In 2002, the prevalence per 1,000 child beneficiaries of antihypertensive prescription use overall was 2.35 (1.12 for beta blockers, 0.65 for ACE/ARB, 0.49 for diuretics, and 0.33 for calcium channel blockers). The prevalence of type 2 antidiabetic prescription use was 0.31, for statins was 0.22, and for antidepressants was 15.65 per 1,000 child beneficiaries. 2002-2005 use of antihypertensives increased by 2% overall (6% among children 15 to 19 years); ACE/ARB and diuretics grew by 20% and 10%, respectively, while use of beta blockers and calcium channel blockers declined (-8% and -16%, respectively). The prevalence rate for type 2 anti-diabetic agents doubled driven by a 166% and 135% increase among females age 10 to 14 and 15 to 19 years, respectively. Statin use declined by 5.5% while use of antidepressants remained relatively flat, growing at a rate of only 2%. Conclusions: The trends in obesity-related drug therapy are not consistent with recent trends in childhood obesity. The negligible increase in antihypertensives, decreased statin prevalence and a doubling of type 2 anti-diabetics over four years suggest a different criteria for screening and treatment for these chronic conditions in children.

Learning Objectives:
1. Describe the prevalence of chronic medication use in children 5 to 19 years of age. 2. Analyze the overall, age and gender specific trends in chronic medication use in children from 2002 to 2005 as it relates to trends in childhood obesity. 3. Discuss the implications of the trend patterns of chronic medication use as it relates to pediatric patient care and treatment guidelines.
