Long-term maternal mortality risk following spontaneous preterm birth: A retrospective cohort study.

ABSTRACT:

Objective

To determine whether women with spontaneous preterm birth (PTB) have increased risks for long-term mortality.

Design

Retrospective cohort.

Setting

Births in Utah between 1939 and 1977.

Population

We included women with a singleton live birth ≥20 weeks who survived at least 1 year following delivery. We excluded those who had never lived in Utah, had improbable birthweight/gestational age combinations, underwent induction (except for preterm membrane rupture) or had another diagnosis likely to cause PTB.

Methods

Exposed women had ≥1 spontaneous PTB between 20⁺⁰  weeks and 37⁺⁰  weeks. Women with >1 spontaneous PTB were included only once. Unexposed women had all deliveries at or beyond 38⁺⁰  weeks. Exposed women
