Disparities in breast cancer screening rates among adults with and without intellectual and developmental disabilities

Individuals with intellectual and developmental disabilities (IDD) may face barriers in accessing health care, including cancer screening and detection services. Analysis of Medicare Standard Analytic Files of 9,383,349 benificiaries aged 65-79 years found that 11,265 (0.1%) met the criteria for IDD. Individuals with IDD had reduced odds of undergoing breast cancer screening (OR 0,77; p<0.001). Breast cancer screening rates in individuals with IDD were further influenced by social vulnerability and belonging to a racial/ethnic minority. The authors conclude that individuals with IDD face additional barriers to breast cancer screening.
