Neonatal outcome	Late preterm mature amniocentesis at 34.0–36.6 wk gestation, n (%)^a	Early-term mature amniocentesis at 37.0–38.6 wk gestation, n (%)^b	Term at 39.0–40.6 wk gestation, n (%)^c	P value^d

Hypoglycemia	18 (23.7)^f	13 (17.1)^f	15 (5.7)	< .01
Intravenous fluids for hypoglycemia	2 (2.6)	2 (2.6)	0	.03
Gavage feeds	8 (10.5)^f	0	0	< .01
Phototherapy	4 (5.3)^f	7 (9.2)^f	3 (1.2)	< .01
Sepsis evaluation	13 (17.1)^f	4 (5.3)	9 (3.5)	< .01
Treatment with antibiotics	2 (2.6)	2 (2.6)	2 (0.8)	.31
Central venous line	1 (1.3)	1 (1.3)	0	.18
Neonatal intensive care admission	14 (18.4)^f	4 (5.3)	8 (3.1)	< .01

n = 76 women;

n = 262 women;

Denotes χ² statistic for comparison among 3 groups for each neonatal outcome;

Consists of neonatal intensive care admission, phototherapy, antibiotic treatment, intravenous fluids for hypoglycemia, or gavage feeding;

Denotes significant difference (P < .05) between the group in the column heading when compared individually to the reference group at ≥39 weeks’ gestation.
