The Effect of Iron Deficiency Anemia Early in the Third Trimester on Small for Gestational Age and Birth Weight: A Retrospective Cohort Study on Iron Deficiency Anemia and Fetal Weight

Table 2

Comparison of delivery outcomes and SGA rates.

	Severe anemia (n = 80)	Moderate anemia (n = 320)	Mild anemia (n = 1300)	Control (n = 3100)	value
Gestational age at delivery (weeks)	39 (38–40)	39 (38–40)	39 (38–40)	39 (38–40)	0.540
Male gender rates	43 (53.7%)	169 (52.8%)	696 (53.3%)	1677 (54%)	0.780
Vaginal delivery rates	52 (65%)	204 (63.7%)	838 (64.4%)	2021 (65.1%)	0.840
Fetal weight (g)	2900 ± 80^a	3050 ± 100^b	3350 ± 310^c	3400 ± 310^c	<0.001
SGA	15 (18.7%)^a	39 (12.1%)^b	70 (5.3%)^c	152 (4.9%)^c	<0.001

Different superscripts mean statistically different. SGA, small for gestational age; values are expressed as median (25^th–75^th percentile) or mean ± SD or n (%).
