Multivariable logistic regression analyses of demographic and clinical factors by time intervals before mothers first saw, held and fed their newborns, controlling for confounders, First Baby Study, Pennsylvania, USA, 2009-2011

Factor	Mother saw newborn right away	Mother held newborn in 5 minutes or less	Mother fed newborn in 30 minutes or less
	Adjusted OR (95% CI)	Adjusted OR (95% CI)	Adjusted OR (95% CI)
Maternal age at delivery, y
18-24	Reference	Reference	Reference
25-29	1.27 (0.96-.69)	1.22 (0.93-1.60)	1.08 (0.86-1.37)
30-36	1.19 (0.88-1.60)	1.09 (0.81-1.47)	1.16 (0.90-1.50)
White non-Hispanic	0.94 (0.72-1.23)	1.01 (0.77-1.34)	0.65 (0.51-0.83)
Private insurance	1.51 (1.15-2.00)	1.12 (0.85-1.49)	1.26 (0.99-1.62)
Mode of delivery
Spontaneous vaginal	7.77 (6.26-9.64)	40.31 (29.58-54.92)	8.17 (6.32-10.56)
Instrumental vaginal	4.71 (3.29-6.74)	30.15 (20.19-45.02)	6.18 (4.36-8.76)
Planned cesarean	1.46 (1.01-2.11)	1.19 (0.63-2.28)	1.71 (1.06-2.75)
Unplanned cesarean	Reference	Reference	Reference
Not late preterm (gestational age of 37 weeks or later)	1.29 (0.81-2.04)	1.44 (0.90-2.31)	1.88 (1.19-2.97)
Not high-risk delivery	1.18 (0.97-1.44)	1.24 (1.02-1.51)	1.07 (0.90-1.26)
No fetal congenital conditions	1.10 (0.76-1.60)	0.68 (0.45-1.02)	1.05 (0.74.-1.47)
No maternal morbidities	1.15 (0.93-1.42)	1.40 (1.14-1.73)	1.42 (1.18-1.70)
No neonatal morbidities	2.16 (1.6-2.79)	2.92 (2.23-3.83)	2.68 (2.04-3.54)
Midwife or doula attended birth	1.29 (1.04-1.60)	1.44 (1.17-1.78)	1.09 (0.91-1.30)

Each of the three multivariable logistic regression models controls for maternal age, race, insurance coverage, mode of delivery, late preterm delivery, high-risk delivery, fetal congenital conditions, maternal morbidities, neonatal morbidities and the support of a midwife or doula during labor.
