Association between European admixture and phenotypes (standardised parameter estimate and p-value shown, respectively)
| Entire sample | Hispanic Americans | African Americans | European Americans | |
|---|---|---|---|---|
| Total fat | 0.13 (p = 0.037*) | -0.12 (p = 0.40) | 0.17 (p = 0.090) | 0.02 (p = 0.80) |
| SI | 0.34 (p < 0.0001*) | 0.25 (p = 0.031*) | -0.01 (p = 0.93) | 0.13 (p = 0.18) |
| AIRg | -0.28 (p < 0.0001*) | -0.23 (p = 0.038*) | -0.13 (p = 0.19) | -0.09 (p = 0.37) |
| FI | -0.20 (p = 0.0013*) | -0.27 (p = 0.045*) | -0.07 (p = 0.45) | -0.02 (p = 0.79) |
| HOMA-IR | -0.16 (p = 0.0095*) | -0.26 (p = 0.064) | -0.11 (p = 0.25) | -0.005 (p = 0.96) |
Covariates: age, sex, Tanner stage, SES, total fat, height (for AIR, we also controlled for SI).
*p < 0.05.
SI, insulin sensitivity; AIRg, acute insulin response to glucose; FI, fasting insulin; HOMA-IR, Homeostasis model assessment of insulin resistance.
