Interpregnancy interval after stillbirth: Modifiable, but does it matter?

This article discusses evidence that interpregnancy interval, defined as the time from the end of one pregnancy to the conception of the next, is associated with increased risk of an adverse outcome (miscarriage, perinatal death, preterm birth, low birthweight, and small-for-gestational-age birth) in the next pregnancy. Although there is consistent evidence that pregnancies conceived less than 18–24 months after a livebirth are at increased risk of adverse outcomes, some recent research has questioned these findings. Despite this recent evidence, World Health Organisation recommendations continue to endorse an interval of at least 24 months after a livebirth, and 12 months after a miscarriage, before another pregnancy.
