Model	Racism-Related Events: Total (Direct + Vicarious; N = 408)	Racism-Related Events: Direct (N = 408)	Racism-Related Events: Vicarious (N = 408)


Model 1. Unadjusted	0.12 (0.04, 0.20)^*	0.24 (0.13, 0.35)^*	0.04 (−0.14, 0.21)
Model 2. Adjusted for sociodemographic factors^a	0.14 (0.06, 0.22)^*	0.26 (0.14, 0.37)^*	0.07 (−0.10, 0.2)
Model 3. Model 2 + risk factors for poor sleep^b	0.14 (0.06, 0.22)^*	0.26 (0.15, 0.36)^*	0.09 (−0.08, 0.26)
