In 2020, COVID was the leading cause of death for people with intellectual and developmental disabilities, researchers report.
For a new study, the researchers looked at 2020 death certificate data to examine death patterns for people with or without an intellectual and developmental disability (IDD).
They found that for those without an IDD, COVID was the third leading cause of death, following heart disease and cancer. But for those with IDD, COVID was the number one cause of death.
IDD are conditions characterized by life-long impairments in mobility, language, learning, self-care, and independent living. Examples include Down Syndrome, cerebral palsy, and intellectual disabilities.
The study confirms earlier predictions that COVID-19 would be deadlier among people with IDD, says Scott Landes, associate professor at Syracuse University and lead author of the paper in Disability and Health Journal.
“Even when we adjusted for age, sex, and racial-ethnic minority status, we found that COVID-19 was far deadlier for those with IDD than those without,” says Landes. “Furthermore, people with IDD were dying at much younger ages.”
To understand why the COVID-19 burden is greater for people with IDD, the researchers feel that more attention needs to be given to comorbidities as well as living arrangements.
“People with IDD are living in congregate settings at a higher percentage than those without an IDD,” says Landes. “Group living situations, especially with close-contact personal care support, is associated with the spread of COVID-19. For the estimated 13% to 20% of adults with IDD living in these settings, the risk cannot be overstated.”
“While it is important to attend to differences in comorbidity patterns, it is also necessary to realize that the increased COVID-19 burden among people with IDD may at least partly be due to social factors such as a higher proportion of this population living in group care settings, insufficient attention to care needs on a public and private level, and inequities in access to quality health care,” says Landes.
Additionally, the researchers note the higher occurrences of hypothyroidism and seizures among all IDD statuses, and obesity among decedents with intellectual disability and Down syndrome. “Out of an abundance of caution, medical providers should carefully monitor symptoms among COVID-19 patients with IDD diagnosed with hypothyroidism and/or seizures.”
But the researchers say that more work is needed to explore these social factors to better understand the COVID-19 death rates for people with IDD.
Furthermore, the authors note that the study is focused on the first year of the COVID-19 pandemic. A current data inequity that permits IDD to be reported as the cause of death prevents understanding whether people with IDD continue to experience a disproportionate COVID-19 burden.
“This is preventing adequate surveillance of the health of this marginalized population during the ongoing pandemic. While changes are needed to the death certificate coding and revision process to address this data inequity in the long-term, in the immediate, the CDC will need to recognize this inequity and take necessary action to allow for analysis of current death certificate data at the decedent level for this population,” Landes says.
