Pregnant Women Living or Working with Smokers May Have Higher Risk of Stillbirth


Living or working with smokers may increase a pregnant woman’s risk of having a stillbirth, a new study suggests. Pregnant women who breathe in secondhand smoke are also more likely to give birth to babies who weigh less.

Reuters reports that the study included nearly 12,000 women, 11 percent of whom said they had been exposed to secondhand smoke. The researchers found that women who breathed in passive smoke had more than three times the risk of stillbirth compared with women who did not breathe in other people’s smoke.

The study, published in BJOG: An International Journal of Obstetrics and Gynecology, also found that babies born to women who breathed in secondhand smoke weighed nearly 2 ounces less than babies whose mothers were not exposed to smoke at home or at work.

The researchers said that undiluted secondhand smoke could harm a fetus by restricting blood flow and damaging the placenta.

    This is scientific fraud, because they deliberately use studies that ignore the role of infection in order to falsely blame smoking. “We recently found no significant association between maternal smoking and either stillbirths or neonatal deaths when information about the underlying disorders, obtained from placental examinations, was incorporated into the analysis. Similar analyses found no correlation between maternal smoking and preterm birth. The most frequent initiating causes of preterm birth, stillbirth, and neonatal death are acute chorioamnionitis, disorders that produce chronic low blood flow from the uterus to the placenta, and major congenital malformations. There is no credible evidence that cigarette smoking plays a role in the genesis of any of these disorders.” (RL Naeye.
