Cho GJ, et al. - In this population-based cohort study of 115,629 women with two consecutive deliveries during the study period, researchers examined whether a history of threatened preterm labour (TPL) followed by term delivery is associated with the risk of spontaneous preterm delivery (PTD) in subsequent pregnancy. Analyzing data of the National Health Insurance Claims Database and a national health-screening programme for infants and children in South Korea, they identified that PTD risk during a subsequent pregnancy in women with a history of TPL followed by term delivery was lower when compared to those with history of previous PTD but was significantly higher when compared to those who delivered at term without TPL.
