Abstract

OBJECTIVE:

To examine the effect of interpregnancy interval (IPI) on outcomes of pregnancy after recurrent pregnancy loss (RPL).

METHODS:

A retrospective cohort study including 325 patients treated at a RPL clinic, with two or more consecutive pregnancy losses followed by a subsequent (index) pregnancy, of whom 163 had IPI ≤ 6 months, and 212 had IPI > 6 months.

RESULTS:

Pregnancy loss rate in the index pregnancy was positively associated with increased IPI (18.6% in women with IPI ≤ 6 months, and 29.7% in women with IPI > 6 months; p = 0.029). In a multivariable logistic analysis, excluding women with fertility problems, and adjusting for maternal age and ethnicity, the OR for pregnancy loss rate for IPI longer than 6 months compared to shorter IPI was 1.76 (95%CI: 0.96-3.22, p = 0.067).

CONCLUSIONS:

Our results suggest that IPI shorter than 6 months, in women with no fertility problems, is associated with lower rate of subsequent miscarriage. Further studies are needed to substantiate this finding.
