(BJOG. 2015;122:1377–1385) The aim of the study undertaken was to assess the changes in perinatal outcomes in children born from 37 weeks of gestation after implementation of a more proactive labor induction practice from 2009. This register-based historical cohort study included all newborns in Denmark delivered from January 1, 2000 to December 31, 2012. To reduce the random year-to-year variation, the 13-year study period was subdivided into 5 intervals of 3, 3, 3, 2, and 2 years.
