Multinomial Regression Predicting Birth Weight by Gestation

	SGA versus Normal for Gestational Age	LGA versus Normal for Gestational Age
BMI	p = 0.89	p = 0.09
Underweight	1.21 (0.69–2.12)	0.46 (0.10–2.10)
Normal	1.00	1.00
Overweight	1.19 (0.65–2.18)	2.16 (0.98–4.75)
Obese	1.00 (0.55–1.82)	1.00 (0.45–2.20)
Weight gain	p = 0.001^*	p = 0.008^*
Undergain	1.99 (1.11–3.55)^*	0.21 (0.02–1.67)
Appropriate gain	1.00	1.00
Overgain	0.75 (0.44–1.28)	2.52 (1.08–5.89)^*

p < 0.05.

Note: Controlling for cigarette use, alcohol use, age, parity, race, gestational age at delivery, and study intervention condition. BMI, body mass index; SGA, small for gestational age; LGA, large for gestational age.
