Some small for gestational age fetuses have higher risk of late fetal death than others

In small for gestational age fetuses, without congenital malformations, constitutionally small fetuses $---$ for example twins orthe fetuses of short mothers $---$ have been assumed to at lower riskof late fetal death than fetuses affected by conditions such aspre-eclampsia or cigarette consumption. Cnattingius et al (p 1483)tested that assumption in over 1 million births in the Swedishbirth register. Overall, late fetal mortality was increased inwomen who were over 35, nulliparous, smoked, or were $=<$ 155 cm talland greatly increased in those with pre-eclampsia, essential hypertension,and twin pregnancies. But in very small for gestational age fetusesdeath rates were lower in women aged under 35, $=<$ 155 cm tall, withtwins, or with severe eclampsia or hypertension.
