ABSTRACT
Despite the significant increase in the risk of colorectal cancer (CRC), one-third of individuals with diabetes who met screening recommendations, reported not being up-to-date on CRC screening in the United States. We determined the means through which individuals with type 2 diabetes (T2DM) learned about diabetes care; we further examined their associations with CRC screening uptake. This was a retrospective study of US adults aged 50-75â¯years diagnosed with T2DM (sample nâ¯=â¯5595, representing 14,724,933 Americans). Data from the 2011-2014 Medical Expenditure Panel Survey were analyzed to compare CRC screening uptake in four learning groups for diabetes care: (1) did not learn, (2) learning from health providers only, (3) learning from other sources (including online sources and group class), and (4) learning from health providers and other sources together (combined learning group). Overall, 70.4% individuals with T2DM were up-to-date with CRC screening during 2011-2014. In multivariate logistic regression analysis, the combined learning group had 1.32 (95% confidence interval, 1.01-1.74) times higher odds of being up-to-date on CRC screening than those who did not learn about diabetes care. The odds of being up-to-date on CRC screening were not significant for other learning groups. Our findings suggest that combined ways of health information delivery for diabetes care is associated with increased odds of being up-to-date on CRC screening among individuals with T2DM. Multimodal health information delivery has the potential to result in unintended, positive consequences in preventive care services use.
