Background. While active maternal tobacco smoking has well established adverse perinatal outcomes, the effects of passive maternal smoking, also called environmental tobacco exposure (ETS), are less well studied and less consistent. Objective: To determine to the effect of ETS on perinatal outcomes. Search strategy. Medline, EMBASE and reference lists were searched. Selection criteria. Studies comparing ETS‐exposed pregnant women with those unexposed which adequately addressed active maternal… 

Systematic review and meta-analysis of maternal secondhand smoke exposure and neonatal outcomes

In all analyses, the odds of having negative outcomes were greater among studies conducted in MICs than in HICs, and the quality of studies in middleand high-income countries (MIC and HIC) was of lower quality on average than those conducted in Hics.

Reducing second-hand smoke exposure among non-smoking pregnant women: a systematic review.

There is mixed evidence for interventions aimed at reducing pregnant women's exposure to second-hand smoke, though multi-component interventions seem to be more effective.

Clinical interventions to reduce secondhand smoke exposure among pregnant women: a systematic review

Clinical interventions delivered in prenatal care settings appear to reduce secondhand smoke exposure among non-smoking pregnant women, but study weaknesses limit the ability to draw firm conclusions.

Environmental risk factors of pregnancy outcomes: a summary of recent meta-analyses of epidemiological studies

The methodologies used in these recent meta-analyses of environmental exposures and pregnancy outcomes are described to describe the methodologies and their main findings are reported.

The Influence of Maternal Smoking and Exposure to Residential ETS on Pregnancy Outcomes: A Retrospective National Study

The results showed strong effects of smoking throughout the pregnancy on reduced birthweight, birth length and head circumference, and increased risk for LBW.

Gender Difference in the Association between Environmental Tobacco Smoke and Birth Weight in Africa

Exposure to ETS is significantly associated with low birthweight in Africa, mainly among male newborns, and a public health promotion on behavioral changes is likely to have a positive impact on newborns’ health.

Associations between Passive Maternal Smoking during Pregnancy and Preterm Birth: Evidence from a Meta-Analysis of Observational Studies

It is demonstrated that passive maternal smoking is associated with an increased risk of preterm birth.

Influence of maternal environmental tobacco smoke exposure assessed by hair nicotine levels on birth weight.

Maternal ETS exposure during pregnancy was inversely related with birth weight, and more comprehensive tobacco control policies are needed to avoid babies being SGA and LBW.

The impact of smoke-free legislation on fetal, infant and child health: a systematic review and meta-analysis protocol

This work aims to comprehensively assess the impact of smoke-free legislation on fetal, infant and childhood outcomes, and to inform further development and implementation of global policy and strategies to reduce early life SHS exposure.



Environmental tobacco smoke and fetal health: systematic review and meta-analysis

Exposure of non-smoking pregnant women to ETS reduces mean birth weight by 33 g or more, and increases the risk of birth weight below 2500 g by 22%, but has no clear effect on gestation or therisk of being small for gestational age.

Effects of passive smoking on outcome in pregnancy.

Exposure to ETS during pregnancy is associated with higher risk of having a small-for-gestation baby and multiple logistic regression analyses showed that ETS exposure during pregnancy was significantly associated with aHigher risk of small- Forgestation babies.

Environmental Tobacco Smoke and Pregnancy Outcome

ETS exposure in pregnant women adversely affects pregnancy by increasing fetal mortality and preterm delivery at higher exposure levels and slowing fetal growth across all levels of ETS exposure.

Cigarette smoking during pregnancy and risk of preeclampsia: a systematic review.

Prevalence of maternal smoking and environmental tobacco smoke exposure during pregnancy and impact on birth weight: retrospective study using Millennium Cohort

UK prevalences of domestic ETS exposure and maternal smoking in pregnancy remain high and ETS exposed infants' birth weights are lowered, showing a dose-response relationship.

Environmental Tobacco Smoke and Risk of Spontaneous Abortion

Nonsmoking pregnant women exposed to ETS may be at increased risk of spontaneous abortion, and the public health consequences of passive smoking regarding early fetal loss may be substantial.

Evidence for an association between environmental tobacco smoke exposure and birthweight: a meta-analysis and new data.

The risk of low birthweight (LBW, < 2500 g) was not increased in infants of ETS-exposed women, but there was a somewhat increased risk for LBW at term (adjusted odds ratio [OR] 1.8), and the pooled estimate of mean birthweight indicated a decrement of 28 g with ETS exposure of nonsmoking women.

Maternal Smoking and Environmental Tobacco Smoke Exposure and the Risk of Orofacial Clefts

This study confirmed the modest association between smoking and orofacial clefts that has been consistently reported, and identified specific phenotypes most strongly affected.

Environmental tobacco smoke exposure and small-for-gestational-age birth.

No effect of environmental tobacco smoke exposure on fetal growth was seen in this relatively homogeneous upper middle class group of women exposed at low levels, but it does not exclude the possibility of an effect in women exposed to higher levels of environmental Tobacco smoke.

Self‐reported nicotine exposure and plasma levels of cotinine in early and late pregnancy

The results of this study indicate that self‐reported smoking information among pregnant women can be trusted, however, among women reporting smoking cessation during pregnancy, the misclassification rate increased with recency of quitting.
