Values are arithmetic means (95% CIs) unless otherwise indicated. All pairwise race-ethnicity comparisons within a category of age or sex differ, P < 0.0001 (t test). *Different from reference group for age or sex comparison within race-ethnicity subgroup, P < 0.05 (Wald F-test). ref, reference group for age or sex comparison within race-ethnicity subgroup; 25(OH)D, 25-hydroxyvitamin D.
2
Estimates for “other” race-ethnicity group (persons with multiethnic background) are not shown but are included in total estimates.
3
The Hispanic subgroup represents the sum of Mexican-American and other Hispanic ethnicities.
