Note. CI = confidence interval. Weighted data were used. Body mass index was log transformed. Models were adjusted for gender, age (spline), marital status, and US nativity.

^aThe sample size for White was n = 758; for Hispanic, n = 823; for Black, n = 213.

^bWorking-class status was defined based on the work of Krieger et al., who designated certain census occupational codes as working class on the basis of the level of supervisory responsibility they entail.¹⁷

^cThe sample size for White was n = 786; for Hispanic, n = 779; for Black, n = 210.

^dThe sample size for White was n = 817; for Hispanic, n = 861; for Black, n = 232.

^eThe sample size for White was n = 686; for Hispanic, n = 710; for Black, n = 163.
