Mom's Who Smoke Increase Child's Risk of Ear Infection

Thursday, 30 October 2008 15:42

Previous studies revealed an association between second-hand smoke and risk of ear infection. Now, scientists in Australia have discovered a link between in utero exposure to smoke and this common childhood disorder.

The researchers pooled data on 8,556 women and their offspring. At age five, children whose mothers had smoked 1-9 cigarettes per day during pregnancy were 60% more likely to have had a middle ear infection, compared with children of nonsmokers. Mothers who smoked 10 to 19 cigarettes per day upped their children's risk of ear infection by 2.6 times; mothers who smoked over 20 cigarettes per day more than tripled their children's likelihood of ear infection. In addition, offspring of heavy smokers were nearly three times as likely to undergo ear surgery than children of nonsmokers, say researchers.
