1Values are medians (IQRs). Macronutrients are adjusted for total energy intake using either the nutrient residual (g) or nutrient density (percent energy) method

2P values compare differences in median intakes between races within region (i.e., black vs. white) using the Wilcoxon two-sample test.

3Global P values compare differences in median intakes across all three regions (i.e., Stroke Buckle vs. Stroke Belt vs. Other) and were calculated using the Kruskal-Wallis test
