“…3±5 In a review of 18 publications, McIntosh 8 reported an overall OR for stillbirth of 1.26. In our study we found that the strongest association was with placental abruption, with an OR of 2.07, which is similar to that found by Spinillo et al 24 (OR 2.36) and Eriksen et al 25 (OR 2.5). It has been proposed that the mechanism for smoking-related placental abruption includes decidual necrosis at the periphery of the placenta, hypovascular villi and microinfarction.…”

Maternal smoking rates in pregnancy have declined, particularly in the non-manual social classes, and perinatal mortality rates have fallen over the last 20 years. We have therefore re-evaluated the relationship between maternal cigarette smoking and pregnancy outcome against this background. A total of 608 stillbirths and 634 infant deaths were identified using the All Wales Perinatal Survey. The cause of death was classified using the clinicopathological system. Maternal smoking rates and social class groupings were compared with those in a cohort of 16047 survivors born to women resident in South Glamorgan. The smoking rate was 37.8% in mothers of babies who died compared with 27.2% in mothers of survivors, an odds ratio (OR) of 1.63 [95% CI 1.44, 1.84]. The OR for unexplained stillbirth was 1.72 [95% CI 1.38, 2.13], placental abruption 2.07 [95% CI 1.29, 3.31], infection 3.70 [95% CI 2.23, 6.13] and sudden infant death syndrome 4.84 [95% CI 3.05, 7.69]. Maternal smoking was not associated with death due to prematurity or a congenital anomaly. Despite changes in smoking habits and the causes of perinatal death, smoking during pregnancy continues to be strongly associated with fetal and infant mortality. It is important that health promotion activities are effective in reducing smoking during pregnancy.

“…The finding that placental abruption occurred less often in p‐PROM than in other preterm births is consistent with other studies. Although women with preterm birth without PROM have not received much attention as a study or reference group for placental abruption, some studies on placental abruption have been restricted to preterm deliveries and have reported a negative or marginal association of p‐PROM with placental abruption (13–16). To our knowledge, the present study is the first to simultaneously compare the risk in p‐PROM with the risk in the whole birth population, as well as the risk in preterm parturients without PROM.…”

“…Thus, the American Obstetric and Gynecological Association has, in any case of p‐PROM, recommended special awareness with respect to placental abruption (12). However, other studies based on stratified analysis of preterm (13–16) or term pregnancies (17) have reported a lower or marginally higher risk of placental abruption in PROM in comparison with pregnancies without PROM at the same gestational age. Thus, the conflicting results may possibly be explained by the choice of reference group.…”

“…For example, case control studies using Washington State birth certificate data estimated that smokers during pregnancy have twice the risk of placenta praevia, a relationship confirmed in a cohort study from the Swedish Medical Birth Registry that examined records of 1.8 million deliveries in that country from 1973-1990 [7,8]. An increase in the odds of premature rupture of membranes associated with smoking has been estimated between 1.6 and 2.1 [9,10]. Most importantly, estimates of the average reduction in birth weight associated with smoking during pregnancy range on the order of 250 grams, and these reductions are dose dependent [11].…”
