Data are N; means in NGSP units (95% CI).
*Adjusted for sex, age, BMI, FPG, 2hPG, FSI, Hgb, MCV, SBP, DBP, ALT, AST, and GGT.
†Glycemic categories include NGT (FPG <5.6 mmol/L and 2hPG <7.8 mmol/L), prediabetes (FPG 5.6–7.0 mmol/L or 2hPG 7.8–11.1 mmol/L), and unrecognized diabetes (FPG ≥7.1 mmol/L or 2hPG ≥11.2 mmol/L).
‡The Wald F test differences across all groups were statistically significant (P < 0.001).
§Pairwise comparison was statistically significant (P < 0.05) compared with the Mexican heritage group.
‖Pairwise comparison was statistically significant (P < 0.05) compared with the Puerto Rican heritage group.
¶Pairwise comparison was statistically significant (P < 0.05) compared with the South American heritage group.
#Pairwise comparison was statistically significant (P < 0.05) compared with non-Hispanic whites.
**Pairwise comparison was statistically significant (P < 0.05) compared with the Dominican heritage group.
