Smokers who quit early in pregnancy aid baby

The findings show that “these severe adverse effects of smoking may be reversible if smoking is stopped early in pregnancy,” Dr. Lesley M. E. McCowan, from the University of Adelaide, Australia, and colleagues comment in the British Medical Journal.

The results come from an analysis of data for 2500 women who were having their first baby. At 15 weeks’ gestation, the women were classified as non-smokers, stopped smokers, or current smokers.

Parents May Underreport Smoking

A Johns Hopkins Children’s Center study has found that the parents and caregivers of children with asthma often underestimate and underreport how much they smoke at home and around their children, giving pediatricians a skewed idea about their patients’ exposure to secondhand smoke.

Because self-reporting inaccurately gauges exposure, pediatricians should use more reliable measures such as obtaining urine samples from children to check for secondhand smoke inhalation, researchers say.

In a study of 81 children with persistent asthma who lived with a smoker, researchers found wide discrepancies between objective tests and parental reports. In addition, nearly one-third of parents and caregivers reported smoking in the car in the child’s presence, a red flag that exposure to secondhand smoke occurs outside the home.

Smoking parents can hook kids on nicotine

“Increased exposure to second-hand smoke, both in cars and homes, was associated with an increased likelihood of children reporting nicotine dependence symptoms — even though these kids had never put a cigarette in their mouths,” said epidemiologist Jennifer O’Loughlin, senior author of the study and a professor at the Universite de Montreal.
