	Regression coefficients
	Unadjusted			Adjusted
Characteristic	Coefficient	95% CI	p	Coefficient	95% CI	p
Maternal education	−0.005	−0.04–0.03	0.71	−0.01	−0.05–0.02	0.47
Income at registration	0.03	0.003–0.06	0.03	0.03	0.002–0.06	0.03

Notes: CI = confidence interval. The income coefficient was adjusted for maternal age, prepregnancy maternal weight, and education. The education coefficient was adjusted for maternal age, prepregnancy maternal weight, and income at the time of registration.

p = 0.05.
