Understanding disparities among women in breast cancer screening adherence is of considerable interest, however prior work has been methodologically limited. Our work longitudinally examines adherence to screening, and determines factors associated with becoming adherent. The cohort consisted of 2, 537, 960 women age 50-74 from Ontario, Canada. Using age as the time scale, a relative rate multivariable regression was implemented under the 3-state transitional model to examine the association between covariates (all time-varying) and the rate of becoming adherent. Individual- and physician-level characteristics played an important role in a woman’s adherence to screening. Our research improves the quality of evidence regarding disparities among women in adherence to breast cancer screening, and provides a novel methodological foundation to investigate adherence for other types of cancer screening, including cervix and colorectal cancer screening.
