Associations Between Cord Blood Leptin Levels, Maternal BMI, and Neonatal Adiposity

	Univariate			Multivariate*
	β value (95%CI)	r	p**	β value (95% CI)	r ***	p**
Exposure	Percent change in leptin per unit increase in maternal BMI
Maternal BMI	2.2 (0.0 – 4.4)	0.18	0.054	1.8 (−0.5 – 4.1)	0.14	0.129
Outcomes	Change in outcome per 10% increase in leptin
Birth Weight (kg)	0.024 (0.012 – 0.036)	0.35	<0.001	0.027 (0.017 – 0.037)	0.45	<0.001
Fat Mass (kg)	0.011 (0.007 – 0.014)	0.48	<0.001	0.010 (0.007 – 0.014)	0.47	<0.001
% Body Fat	0.235 (0.150 – 0.320)	0.47	<0.001	0.218 (0.135 – 0.300)	0.44	<0.001

^*Analyses were adjusted for maternal age at delivery, maternal race, gestational age in days, and neonatal sex

^**p values were calculated from linear regression models
