  6. Methods • Cross-sectional Analysis—to assess patterns of changes over time • Using birth certificate change history from 2000-2012 • Cohort Analysis—to assess cumulative changes over time to a birth cohort • Using births in 1987, 2000, and change history • Simple survival model using SAS PROC LIFETEST
