Implications of idiopathic preterm delivery for previous and subsequent pregnancies

Abstract

Idiopathic preterm birth is associated with emergency cesarean delivery at term in previous pregnancies and infants with lower birth weight in previous and subsequent pregnancies.

The prospects for multiple‐marker screening for preterm delivery: does transvaginal ultrasound of the cervix have a central role?

“…Epidemiological studies have clearly demonstrated that a prior history of PTD is a major risk factor for its recurrence in a subsequent pregnancy 66,67 . It has been suggested that several candidate genes for polymorphisms associated with labor exist 68 .…”

Role of 17 α Hydroxy Progesterone Caproate (17OHPC) in the Prevention of Preterm Labor

“…Although many risk scoring systems have been devised, predicting a preterm birth is difficult. Prior preterm birth is a strong predictor of preterm delivery [2]. Although the pathogenesis of preterm labor is not well understood, progesterone withdrawal is theorized to play a part [3].…”

Prepregnancy counseling: preterm birth

“…Risk factors for preterm delivery were: a history of preterm delivery, smoking during pregnancy, and a history of abortion. Kristensen et al [9] found that a previous spontaneous preterm delivery gives a fivefold risk increase in preterm birth in the next pregnancy compared with women with first term delivery. Adams et al [10] found in a population-based cohort among almost 123,000 white and 56,000 black women that there is a high association between a preterm delivery in the first pregnancy and recurrence in the next one.…”

“…Several studies have shown that there is an increased risk of preterm delivery when the first delivery was preterm [9][10][11]. An early prior spontaneous preterm birth is more predictive of recurrence and is highly associated with subsequent early spontaneous preterm birth [12].…”
