Relevance of the miscarriage-new pregnancy interval.

Wyss P, Biedermann K, Huch A

Clinic and Policlinic of Obstetrics, University Hospital of Zurich, Switzerland.

There is a wide divergence of opinion concerning the interval a woman should wait after a miscarriage before attempting a new pregnancy ("pregnancy interval"). Many authors recommend waiting 3-4 months in order to reduce the risk of another miscarriage [3, 6, 17, 21]. This retrospective study investigated whether a longer pregnancy interval lowers the risk of repeat miscarriage (R-risk) and/or prematurity. The association between parity and R-risk was also analyzed. Results showed that there are no proven reasons to recommend a waiting period between a miscarriage and a subsequent pregnancy, because the R-risk was around 20% irrespective of interval duration. Prematurity too is not influenced by a waiting period after miscarriage. There was, however, an association between parity and R-risk and risk of prematurity: nulliparae were more likely to have a repeat miscarriage (p < 0.05) or a preterm delivery in the next pregnancy (p < 0.05) than women who had already given birth to a child.

hope this is useful.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
