Multinomial logistic regression results for effects of prepregnancy BMI and adequacy of GWG on the latent class membership of postpartum weight

Predictor	Latent classes of postpartum weight
	Initial High Retention- Continued Gain (N= 3,679)	Initial High Retention- Sharp Decline (N=2,407)
	OR (95% CI)¹	OR (95% CI)¹
Prepregnancy BMI:
Normal	(reference group)	(reference group)
Underweight	0.56(0.35–0.89)^*	0.43(0.19–0.97)^*
Overweight	3.16(2.67–3.74)^***	2.52(1.83–3.47)^***
Obese	3.45(2.69–4.43)^***	3.26(2.40–4.41)^***
GWG adequacy:
Adequate	(reference group)	(reference group)
Inadequate	0.63(0.50–0.80)^**	0.39(0.23–0.65)^***
Excessive	2.90(2.418–3.49)^***	6.06(4.21–8.73)^***

adjusted for maternal age, maternal education, household income, parity, and breast feeding at 5 months

Initial Low Retention -Continued Low Gain (N= 37,019) is the referent class in this multinomial model.
