Note. Bolded values are significantly different from 0. A significant Test of Moderated Mediation indicates that there was a significant difference between the indirect path for non-Hispanic Whites (NHWs) and the indirect path for Native Americans (NAs). Cˈ=direct effect. SE = Standard Error. s=seconds. CI = confidence Interval for indirect effects were bootstrapped at 10,000 samples. NA=Native American. NHW=non-Hispanic Whites. Sex and BMI were included as covariates.
