Presence of Multi-Morbidities and Colorectal Cancer Screening Utilization among Breast Cancer Survivors

Purpose: Our study aimed to examine the association between the presence of chronic diseases with guideline-concordant colorectal cancer (CRC) screening utilization among breast cancer survivors. Methods: We analyzed data among women with a history of breast cancer from the 2016, 2018, and 2020 Behavioral Risk Factor Surveillance System. Receipt of guideline-concordant CRC screening was the outcome of interest. Diabetes, coronary heart disease/myocardial infarction, stroke, chronic obstructive pulmonary disease, emphysema/chronic bronchitis, arthritis, depressive disorder, or kidney diseases were included in chronic disease conditions. Results: Among 1324 survivors, those with multi-morbidities (3+ chronic diseases; 88.3%) had higher CRC screening use compared to those with one (84.4%) or two (85.4%) diseases (p-value < 0.05). In multivariable analysis, survivors with multi-morbidities were two times more likely to have CRC screening compared to those with only one disease (OR, 2.10; 95% CI, 1.11–3.98). Among survivors with multi-morbidities, Black women (OR, 14.07; 95% CI, 5.61–35.27), and those with frequent poor physical health (OR, 3.32; 95% CI, 1.57–7.00) were positively associated with CRC screening use. Conversely, survivors with frequent poor mental health were 67% less likely to receive CRC screening (OR, 0.33; 95% CI, 0.14–0.74). Conclusion: Among breast cancer survivors, multi-morbidities were positively associated with CRC screening.
