Objective To compare antidepressant prevalence data in youths across three western European countries (Denmark, Germany, and the Netherlands) with US regional data in terms of age and gender and to show proportional subclass antidepressant (ATD) use. Method A population-based analysis of administrative claims data for the year 2000 was undertaken in 0 to 19-year-old enrollees who were part of the insured populations from four countries having a total of from 72,570 to 480,680 members. Results AID medication utilization in the US dataset (1.63%) exceeded that of three Western European countries (prevalence ranged from 0.11 to 0.54%) by at least 3-fold. There were major variations in the use of subclasses: tricyclic antidepressants (TCAs) predominated in Germany while selective serotonin reuptake inhibitors (SSRls) predominated in the US, Denmark and the Netherlands. Conclusions Cross-national variations should be further explored to understand the factors related to these differences and how prevalence differences relate to effectiveness and safety. Community-based cohorts should be followed to establish outcomes in the usual practice setting. Copyright (c) 2006 John Wiley & Sons, Ltd.
