One of the strongest known risk factors for spontaneous or unexpected preterm birth – any birth that occurs before the 37th week of pregnancy, most often without a known cause – is already having had one. For women in this group who would like to avoid this scenario in their second pregnancy, focusing on weight gain and dietary changes may not be the best strategy. A new study reported at the Society for Maternal-Fetal Medicine’s annual meeting found no connection between weight gain and the risk of repeat preterm birth.

Stress in the second and third months of pregnancy can shorten pregnancies, increase the risk of pre-term births, and may affect the ratio of boys to girls being born, leading to a decline in male babies. These are the conclusions of a study by New York University researchers that investigated the effect on pregnant women of the stress caused by the 2005 Tarapaca earthquake in Chile.
