U.S. children and adolescents are less healthy than their counterparts in other wealthy nations. To help understand why, former Commonwealth Fund Harkness Fellow Dougal Hargreaves and colleagues compared health care utilization rates for children and adolescents in the U.S. with those in the Netherlands, which ranks near the top of countries in child health and well-being. The study was published in the new Health Affairs (Dec. 2015).
