a
Adjusted for age (continuous), years of participant education (≤12, 13‐15, 16, ≥17), ever was on public assistance as an adult (yes, no, missing), and pack‐years of smoking (never, <10, 10‐19, 20‐29, ≥30).
b
Participants who were in the same quartile of daily racism score in 1997 and 2009 based on the 2009 distribution, and participants in the same category of institutional racism based on the three domains queried in 1997 (jobs, housing, police).
