Abstract Body:
PurposeThe nature of the association of comorbidity and functional limitations - which are commonly observed among the elderly - with surveillance mammography utilization among older women diagnosed with breast cancer is not well understood. MethodsWe used Behavioral Risk Factor Surveillance System data from 2009, 2010, 2012, 2014, and 2016 to fit multivariable logistic regression models examining surveillance mammography by comorbidity and functional limitations among older breast cancer survivors aged 65 and older. Models were adjusted for age at interview, race, geographic region, education, marital status, clinical checkup, obesity, physical activity, smoking status, and survival time. A sensitivity analysis examining the association between poor health status and surveillance mammography was conducted by treating poor health status, which was defined as the simultaneous presence of major comorbidities and functional limitations, as the exposures of interest.ResultsOf 2,552 respondents, 88.2% (2,240) were white and the median age was 75 years (range 65-99 years). Those undergoing surveillance mammography were more likely to be younger, married, physically active, living in the Northeast, and without functional limitations or comorbidity (ps<0.05). Of 74.5% (1,902) women who underwent surveillance mammography during the past year, 39.2% (1,001) had at least one major comorbidity; 41.5% (1,060) had functional limitations and 21.8% (557) had poor health status. ConclusionUtilization of surveillance mammography was inversely associated with comorbidity, functional limitations, and poor health status. Hence, these factors may serve as potential barriers to surveillance mammography among older breast cancer survivors.
