Multivariate stepwise linear regression analysis with insulin sensitivity index (G/I) as dependent variable.

Independent variable	Beta coefficient	Standard error	t	P value
Leptin	−0.126	0.063	−1.502	0.045*
Birth weight	−0.004	0.001	−5.057	0.000***
HMW-adiponectin	−0.167	0.053	−3.152	0.08

Model adjusted R ² = 0.251. Independent variables included in the model were HMW-adiponectin (µg/mL), leptin (ng/mL), gestational age (weeks), birth weight (g), body length (cm), head circumference (cm), placenta weight (g), and the type of delivery. *P < 0.05, ***P < 0.001. G/I: glucose/insulin ratio; HMW-adiponectin: high-molecular-weight adiponectin.
