Regressions of SES on ET-1 in blacks and whites

		Blacks (n = 51)					Whites (n = 65)
DV	Step: predictor	ΔR²	Δ F	B (s.e.)	β	P	ΔR²	ΔF	B (s.e.)	β	P
ET-1	1. Covariates	0.068	0.83				0.135	2.34
	(a) Gender			−0.02 (0.07)	−0.03	0.84			−0.15 (0.07)	−0.29	<0.05
	(b) Resting MAP			−0.00 (0.0)	−0.07	0.66			0.00 (0.00)	−0.17	0.20
	(c) BMI			0.00 (0.01)	0.00	0.98			0.00 (0.01)	0.06	0.60
	(d) Exercise			−0.09 (0.05)	−0.28	0.82			−0.06 (0.04)	−0.15	0.18
	2. SES	0.018	0.91	0.00 (0.00)	0.15	0.35	0.210	18.90	0.01 (0.00)	0.49	<0.001

ET-1 was square root transformed for regression analyses. Higher SES and exercise scores, as measured by Hollingshead social index scores and the Leisure Time Exercise Questionnaire, reflect lower SES and lower exercise, respectively.

BMI, body mass index; DV, dependent variable; ET-1, endothelin-1; MAP, mean arterial pressure; SES, socioeconomic status.
