Very nice! The Canadian Longitudinal Study of Aging has longitudinal perceptions of race during spirometry encounters but not much on how people were treated. We recently reported crazy high discrepancies between perceived and self-identified race for many population groups.

Thank you! I am inspired by your research and advocacy

Lung function gaps dropped by up to 26% between Black and White individuals after excluding those with unfavorable exposures. Remarkably, home ownership alone was linked to a 12–13% reduction in disparities among Black and White children.

Starting from a baseline reference population, we show racial gaps in lung function shrink as we sequentially exclude individuals with occupational dusts/fume exposure, inactivity, maternal/second-hand tobacco use, obesity, lack of home ownership and insurance, lower education, and unhealthy diet.
