Fetal complications during pregnancy according to maternal age.

Fetal Complications	Below 17 Years Old (n = 131)	Over 17 Years Old (n = 148)	p-Value a	aOR [95% CI]	p-Value b
Fetal complications	3.1% (4)	7.4% (11)	0.19	0.8 [0.8; 0.9]	0.001
Malformations	2.3% (3)	3.4% (5)	0.60	0.9 [0.8; 0.9]	0.003
Fetal growth restriction	0.8% (1)	3.4% (5)	0.14	0.7 [0.5; 0.9]	0.005
Small for gestational age	0.8% (1)	2.0% (3)	0.38	0.8 [0.5; 0.9]	0.012
Fetal death	0.0% (0)	0.0% (0)	-	-	-

Data show the percentage and sample size (n). ^a p-Value was extracted by the chi-squared test. Adjusted odds ratios (aOR), 95% confidence intervals [95% CI], and ^b p-Value associated was extracted from general regression models adjusted for ethnicity, obstetrical control and parity. The regression models were built considering age as a continuous variable.
