POSSIBLY In this retrospective cohort study from Sweden, when the expected date of delivery was postponed more than 7 days as a result of early (<14 weeks' gestation) or late (>16 weeks) ultrasonographic dating, the risk of a small-for-gestational-age infant
increased (odds ratio [OR], 1.77; 95% confidence interval [CI], 1.13-2.78 and OR 2.09; 95% CI, 1.59-2.73).

Similarly, women who have had a preterm or small-for-gestational-age infant
in one pregnancy are more likely to have a baby who dies from SIDS in the next pregnancy.
Higher maternal body mass index before pregnancy has been associated with a lower risk of having a small-for-gestational-age infant
and an increased risk of late fetal death and NTDs (Cnattingius et al.
The analyses were adjusted for maternal age, education and parity; smoking and alcohol use during pregnancy; gestational age; birth weight; and prenatal high-risk conditions (maternal anemia, intrapartum fever, preterm premature rupture of the membranes, excess amniotic fluid, diabetes, chronic hypertension, pregnancy-induced hypertension, renal disease, premature detachment of the placenta, placenta previa, bleeding of unknown cause, fetal growth restriction, Rh sensitization, postterm pregnancy and history of delivering a preterm or small-for-gestational-age infant
The analysis was unable to find any subset of women for whom aspirin was ineffective for preventing preeclampsia, including women with preexisting diabetes, renal disease, or chronic hypertension, and women who previously delivered a small-for-gestational-age infant
Likewise, after controlling for maternal age and race, the odds ratio for delivery of a small-for-gestational-age infant
, compared with women with no vasculopathy, was highest in those with proliferative retinopathy and nephropathy (see graph below).
One hundred thirteen small-for-gestational-age infants
born in India at 35 weeks of gestation or later were randomly assigned to delayed cord clamping (DCC; at 60 seconds) or early cord clamping (ECC; immediately after birth).
