Mixed linear models for the dependant variable first-phase insulin secretion

	Estimate	s.e.	P
First-phase insulin secretion (obese subjects only)
Intercept	–0.990	1.486	0.508
S _I	–0.281	0.105	0.010
Total fat	0.935	0.208	<0.001
AfADM	0.005	0.002	0.062
First-phase insulin secretion (lean subjects only)
Intercept	–1.378	1.624	0.419
S _I	0.032	0.119	0.782
Total fat	0.344	0.141	0.145
AfADM	0.006	0.002	0.014

Models were conducted separately within the obese and lean subgroups. All models were adjusted for age, pubertal stage, age-nested-in-pubertal stage, and SES.

AfADM, African genetic admixture; SES, socioeconomic status; S_I, insulin sensitivity index.
