To investigate whether the effect modification of smoking by maternal age previously reported for small for gestational age births was also obtained for late fetal death and placental abruption, the author analyzed single births in Sweden (n = 1,057,711) from 1983 to 1992. An effect modification of smoking by maternal age was obtained only with regard to fetal growth: Compared with nonsmokers aged 40-44 years, the risk of small for gestational age births among women smoking at east 10…

Advanced Maternal Age and Nicotine Consumption during Pregnancy: Additive Effects on Newborn Parameters
TLDR
Increasing maternal age amplified the negative effects of smoking during pregnancy on newborn parameters, identifying older smoking mothers as a high-risk group which should be of special interest for public health systems.
The Effects Of Smoking On Pregnant Women
TLDR
Smoking during pregnancy continues to be an important risk factor for maternal and fetal outcomes during pregnancy and it might increase risks of behavioral disorders in childhood.
Prenatal Smoking Cessation and the Risk of Delivering Preterm and Small-for-Gestational-Age Newborns
TLDR
Pregnant smokers who quit in the first trimester lowered their risk of delivering preterm and SGA newborns to a level similar to that of pregnant nonsmokers, and this benefit appeared to increase with maternal age.
Maternal Smoking and Birth Weight: Interaction With Parity and Mother's Own In Utero Exposure to Smoking
TLDR
A mother's prenatal exposure to smoke may affect the birth weight of her offspring, and this effect would be consistent with both the accumulation-of-risk and the fetal-programming hypotheses.

TLDR
Smoking during pregnancy is in many countries recognized as the most important preventable risk factor for an unsuccessful pregnancy outcome.
The influence of maternal cigarette smoking on placental pathology in pregnancies complicated by abruption.
Differences in late fetal death rates in association with determinants of small for gestational age fetuses: population based cohort study
TLDR
Although the risk of late fetal death is greatly increased in fetuses that are extremely small for gestational age the risk is strongly modified by underlying determinants—for example, there is a lower risk ofLate fetal death in a small for Gestational age fetus if the mother is of short stature, has a twin pregnancy, or has hypertension.
Advanced Maternal Age, Pregnancy and Birth
TLDR
Four groups of advanced maternal age women are distinct highriks groups, who should be identified early in maternity care clinics as being “at risk” when the potential complications could be detected early and the harm for both the mother and the foetus could be prevented and reduced.
Risk Factors for Neonatal/Maternal Morbidity and Mortality in African American Women with Placental Abruption
TLDR
Lower gestational age at delivery is the most important risk factor for poor neonatal outcome in African American women with placental abruption, and preeclampsia was associated with a better maternal outcome in the multivariate analysis.
Maternal use of nicotine replacement therapy during pregnancy and offspring birthweight: a study within the Danish National Birth Cohort.
TLDR
The results of this study suggest that maternal use of NRT in pregnancy does not seriously affect birthweight, but there could be a negative effect on birthweight associated with simultaneous use of more than one type of N RT product.

Birth weight and smoking during pregnancy--effect modification by maternal age.
TLDR
The effect of exposure to cigarette smoking during pregnancy is modified by advancing maternal age, suggesting that the public health question of whether smoking cessation programs ought to focus limited resources more selectively toward pregnant smokers in particular age groups is better addressed.
The effects of maternal smoking on fetal and infant mortality.
TLDR
It was estimated that if all pregnant women stopped smoking, the number of fetal and infant deaths would be reduced by approximately 10%.The higher rate of mortality among blacks compared with whites could not be attributed to differences in smoking or the other four maternal characteristics studied.
Cessation of smoking during pregnancy improves foetal growth and reduces infant morbidity in the neonatal period. A population‐based prospective study
TLDR
All pregnant women in Uppsala county in 1987 were questioned on three different occasions about smoking habits, socio‐demographic factors and obstetric history, and the mean birth weight and perinatal morbidity rate in mothers of mothers who stopped smoking were almost identical to those in infants of non‐smokers.

Smoking in pregnancy: effects of stopping at different stages
TLDR
Standardized mean birthweights were greater for all groups who stopped than for persistent smokers, and those who stopped before 6 weeks and between 6 and 16 weeks gestation had infants heavier than the persistent smokers and similar to the non‐smokers.
Intrauterine growth curves based on ultrasonically estimated foetal weights
TLDR
New growth curves are presented based on data from four Scandinavian centres for 759 ultrasonically estimated foetal weights in 86 uncomplicated pregnancies, revealing better the true distribution of SGA foetuses and neonates and are suggested for use in perinatological practice.
Maternal Smoking Reduces Prostacyclin Formation in Human Umbilical Arteries: A Study on Strictly Selected Pregnancies
TLDR
Production of prostacyclin(PGI2)‐like activity in umbilical arteries in vitro was evaluated in 38 selected newborn infants and it was found that decreased production of PGI2‐like activities might have an impact on nutritive blood flow and oxygen transport, especially in situations of asphyxia.
Risk factors for abruptio placentae.
TLDR
Overall, the association with cigarette smoking during pregnancy was of only borderline significance, although there appeared to be a dose-response relation between the number of cigarettes smoked and risk of abruption.
