Abstract

BACKGROUND: The aim of this study was to assess the outcome of twin pregnancies in women of advanced age (35 years) compared with women aged 25–29 years old.

METHODS: This population-based retrospective study compared perinatal outcome of twin pregnancies in primiparae aged 35 or older (N 5 240) to that of twin pregnancies in primiparae aged 25–29 years (N 5 940). Observed outcomes are adjusted for intermediate (mode of conception and hypertension during pregnancy) and confounding variables (level of education). The possible effect of zygosity and chorionicity was tested in a subset of this database, recorded in the East Flanders Prospective Twin Survey (EFPTS).

RESULTS: In twin pregnancies, maternal age of 35 or over is associated with a lower incidence of preterm birth [adjusted odds ratio (AOR) 0.59, 95% confidence interval (CI) 0.44–0.79] and low birthweight (AOR 0.75, 95% CI 0.58–0.98) compared with younger women. Differences in zygosity and chorionicity between both cohorts do not seem to affect the result.

CONCLUSIONS: In comparison with primiparae aged 25–29 years, perinatal outcome of twin pregnancies is more favourable in primiparae aged 35 or over.
