Incretin responses in African American (AA) and European American (EA) children following ingestion of a mixed meal. Data are means ±SD, ■AA n=34 □EA n=18. “Early response” is defined as the area-under-the curve (AUC) for minutes 0-30 and “late response” as the AUC for minutes 30-180 post challenge. Means were compared by independent samples t-tests.
Panel A. *AA had lower early (P=0.03) and lower late (P=0.04) glucagon-like peptide-1 (GLP-1) responses compared to EA.
Panel B. Mean early (P=0.12) and late (P=0.17) glucose-dependent insulinotropic polypeptide (GIP) responses did not differ in AA and EA children.
