OBJECTIVE: To determine the risk of adverse fetal outcomes of secondhand smoke exposure in nonsmoking pregnant women. METHODS: This was a systematic review and meta-analysis in accordance with Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. We searched Medline and Embase (to March 2009) and reference lists for eligible studies; no language restrictions were imposed. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by using random-effect…

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.

Secondhand Smoke Exposure During Pregnancy and Mothers’ Subsequent Breastfeeding Outcomes: A Systematic Review and Meta-Analysis

Meta-analysis of two studies established that the odds of discontinuation of any brestfeeding before six months were significantly increased in the secondhand smoke exposed women, and more research is necessary to understand the association between second hand smoke and the initiation, prevalence and duration of breastfeeding.

Congenital malformations are associated with secondhand smoke among nonsmoking women: A meta-analysis.

Findings highlight the necessity of improving community awareness to prevent secondhand smoke exposure during the preconception and conception periods and increase the risk for overall and several organ-system malformations.

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.

Association Between Exposure to Secondhand Smoke During Pregnancy and Low Birthweight: A Narrative Review

It is revealed that maternal exposure to environmental smoke is correlated with LBW in infants as well as numerous other adverse effects.

Prenatal exposure to secondhand smoke may increase the risk of postpartum depressive symptoms.

A positive association between secondhand smoke exposure during pregnancy with postpartum depressive symptoms was identified and maternal smoking during pregnancy did not appear to modify the association between SHS and PPDS.

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.

Relation of Second Hand Smoker and Effect on Pregnancy Outcome and Newborns Parameters

Exposure to environmental cigarette smoke, during pregnancy is associated with increased fetal complications, as indicated by results of a cross sectional study conducted on 1500 non smoker pregnant women.

Caffeine intake during pregnancy and adverse birth outcomes: a systematic review and dose–response meta-analysis

There is insufficient evidence to support further reductions in the maximum recommended intake of caffeine, but maintenance of current recommendations is a wise precaution.

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.

Associations between adult and childhood secondhand smoke exposures and fecundity and fetal loss among women who visited a cancer hospital

Reports of exposures to SHS during childhood and as an adult were associated with increased odds for prenatal pregnancy difficulties, and underscore the public health perspective that all people, especially women in their reproductive years, should be fully protected from tobacco smoke.

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.

Female exposure to second-hand smoke as a child or in utero may be associated with an increased risk of spontaneous abortion in adulthood, however, this may be a chance finding due to multiple comparisons.

Craniosynostosis and maternal smoking.

The results suggest moderately increased risk of craniosynostosis among mothers who were the heaviest smokers and who continued to smoke after the first trimester.

Among 4,687 women undergoing prenatal care in Orebro County, Sweden, from October 1980 to June 1983, 678 nonsmokers reported passive exposure to tobacco smoke. Of these women, 267 had been passively

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.

Risk of spontaneous abortion in women with childhood exposure to parental cigarette smoke.

Future large studies of pregnancy loss are needed that can distinguish women's tobacco smoke exposure in childhood from that taking place in utero, and suggestive evidence for increased risk of failed embryo implantation among women reporting current secondhand tobacco Smoke exposure is found.
