Abstract
Blind and deaf individuals comprise large populations that often experience health disparities, with those from marginalized gender, racial, ethnic and low-socioeconomic communities commonly experiencing compounded health inequities. Including these populations in precision medicine research is critical for scientific benefits to accrue to them. We assessed representation of blind and deaf people in the All of Us Research Program (AoURP) 2018–2023 cohort of participants who provided electronic health records and compared it with the Centers for Disease Control and Prevention 2018 national estimates by key demographic characteristics and intersections thereof. Blind and deaf AoURP participants are considerably underrepresented in the cohort, especially among working-age adults (younger than age 65 years), as well as Asian and multi-racial participants. Analyses show compounded underrepresentation at the intersection of multiple marginalization (that is, racial or ethnic minoritized group, female sex, low education and low income), most substantively for working-age blind participants identifying as Black or African American female with education levels lower than high school (representing one-fifth of their national prevalence). Underrepresentation raises concerns about the generalizability of findings in studies that use these data and limited benefits for the already underserved blind and deaf populations.

Supplementary information
Supplementary Table 1
aAll Hispanic-identifying participants were grouped as ‘Hispanic’ (without listing race), with the other ethnic group comprising only non-Hispanic participants. The AoURP does not currently provide data about American Indian and Alaska Native participants. b‘Poor’ families are defined as those with incomes below the 2018 federal poverty threshold. ‘Near poor’ families have household incomes of 100% to less than 200% of the poverty threshold. ‘Not poor’ families have household incomes over 200% of the threshold. Thresholds are calculated using incomes ranging from $12,140 to $55,340 depending on household size.
