BACKGROUND: In 2009, the United States Preventive Services Task Force (USPSTF) recommended against routine mammography screening for @entity1 aged 40-49  years. This revised recommendation was widely criticized and has sparked off intense debate. The objectives of this study are to examine the impact of the revised recommendation on the proportion of @entity1 receiving mammograms and how the effect varied by age. METHODS: We identified @entity1 who had continuous health insurance coverage and who did not have @entity0 between 2008 and 2011 in the Truven Health MarketScan Commercial Claims Databases using mammogram procedure codes. Using @entity1 aged 50-59  years as a control group, we used a differences-in-differences approach to estimate the impact of the revised recommendation on the proportion of @entity1 ages 40-49  years who received at least one mammogram. We also compared the age-specific changes in the proportion of @entity1 ages 35-59  years who were screened before and after the release of the revised recommendation. RESULTS: The proportion of @entity1 screened among the 40-49 and 50-59 age groups were 58.5 and 62.5%, respectively, between 2008 and 2009, and 56.9 and 62.0%, respectively, between 2010 and 2011. After 2009, the proportion of @entity1 screened declined by 1.2 percentage point among @entity1 aged 40-49  years (P  <  0.01). The proportion of @entity1 screened decreased for all ages, and decreases were larger among @entity1 closer to the 40-year threshold. CONCLUSIONS: The 2009 USPSTF @entity0 recommendation was followed by a small reduction in the proportion of insured @entity1 aged 40-49  years who were screened. Reductions were larger among @entity1 at the younger end of the age range, who presumably had less prior experience with mammography than @entity1 nearing 50.
