Babies who sleep with smoker parents exhibit high nicotine levels. Retrieved November 10, from www. Prenatal smoking increases the risk of stillbirth, neonatal mortality death of a live-born baby within 28 days 10 and infant mortality. An increased risk of SIDS when babies are exposed to tobacco smoke both during pregnancy and after birth has been found in numerous epidemiological, case-control and cohort studies from around the world.
A recent meta-analysis of 35 case-control studies reported a dose-response relationship, meaning that the more cigarette smoke the baby is exposed to, the higher the risk of sudden infant death. Co-sleeping sleeping on the same sleep surface with an infant greatly increases the risk for SIDS if the mother smokes and if both parents smoke.
Several studies have identified that babies exposed to maternal smoking before and after birth do not arouse as readily as babies who were not exposed. It is currently thought that a failure to arouse from sleep contributes to the final pathway to SIDS Babies exposed to maternal smoking before birth have been shown to have disrupted sleep patterns, 17 increased irritability 5 and decreased control of heart rate.
Smoking is one of the most important modifiable risk factors in reducing the risks of sudden infant death with international agreement that the evidence now demonstrates a causal association. A case-control study of the nicotine and cotinine a metabolite of nicotine levels in the body fluids and hair of babies who had died from SIDS found that the babies of mothers who reported having smoked during pregnancy had higher nicotine levels than the babies of non-smoking mothers.
The authors then looked at the way the babies were fed and found that the cotinine and nicotine levels were not significantly higher in the breast fed babies of smoking mothers compared to those who did not smoke, suggesting that the transfer of nicotine and cotinine in breast milk was not a significant factor and that passive smoking was the major cause of the observed high levels.
Never smoke in a car that carries children. The only way to protect children from third-hand smoke is to have a smoke-free home and car. Every child has the right to live and grow in a smoke-free environment.

In univariable and multivariable logistic regression, there were no statistical differences in frequent or any bedsharing among either prenatal or postpartum smoking mothers compared with nonsmokers; the adjusted odds ratio for postpartum smokers who frequently bedshared was 0.
Results for prenatal smoking were similar. This is the first US population-based study to look at the prevalence of bedsharing among smoking and nonsmoking mothers. Bedsharing is common in Oregon, with There was no significant association between smoking and bedsharing for either prenatal or postpartum smokers among any racial or ethnic group.
Smoking mothers were as likely to bedshare as nonsmoking mothers. The frequency of bedsharing in Oregon was similar to estimates from other sources. Our study has the advantage of being a population-based sample drawn from birth certificates, weighted for nonresponse.
Conclusions: Although a number of case series have raised concerns about the safety of mother-infant bedsharing, even among nonsmoking mothers, this has not yet been confirmed by careful, controlled studies.
There have been 9 large-scale case-control studies of the relationship between bedsharing and SIDS.
