Stillbirth Risk Up After First Preterm or SGA Birth.

Résumé (français) :

Abstract (English):

Women who give birth preterm or deliver a child who is small for gestational age are more likely to have a stillbirth in a subsequent pregnancy, compared with those whose babies are normal weight or born at term, Pamela J. Surkan said at the annual meeting of the American Public Health Association.

Overall, the risk of a subsequent stillbirth tripled in women who delivered preterm compared with those who delivered at term or later in an analysis of 410,021 women in the Swedish National Birth Registry. The results “could help physicians identify women at risk for stillbirth with a second pregnancy and increase surveillance of women with a history of small-for-gestational-age” infants, said Ms. Surkan, a doctoral student at the Harvard School of Public Health, Boston.

The women delivered singletons between 1982 and 1997 and subsequently delivered second children, 1,062 of whom were stillborn. The risk for subsequent stillbirth increased more after a preterm delivery than after delivery of a small-for-gestational-age (SGA) child in a univariate analysis, said Ms. Surkan, who worked on the study as a guest at the Karolinska Institute, Stockholm, Sweden.

Combining preterm delivery and SGA status further increased the risk for later stillbirth in a multivariate analysis that controlled for potential maternal risk factors such as age, smoking, body mass index, educational level, time interval between pregnancies, year of the second delivery, mother's country of origin, and whether or not she lived with the baby's father.

The study showed that women who delivered normal-weight infants before 32 weeks' gestation were twice as likely to have a subsequent stillbirth, compared with those who delivered normal-weight infants later in pregnancy.

For those who delivered SGA infants, the risk of subsequent stillbirth doubled if the first child was born at term (37 weeks or later), quadrupled if the first child was born moderately preterm (at 32-36 weeks), and was six times higher if the first child was very preterm (before 32 weeks), compared with women who delivered non-SGA infants at term.
