"This study clearly shows that preventing exposure to tobacco smoke during pregnancy and postnatally may reduce the risk of hearing problems in children," said Koji Kawakami from the Kyoto University in Japan. The study, published in the journal Pediatric and Perinatal Epidemiology, included data from 50,734 children aged three years.
Out of the group, 3.8 percent were exposed to smoking only during pregnancy, 3.9 percent were exposed only to second-hand smoke at 4 months, and 0.9 percent were exposed to tobacco smoke during pregnancy and at 4 months.
The results showed that the prevalence of hearing impairment among babies aged three who were exposed to smoke was 4.6 percent while those exposed to only second-hand smoke at 4 months had a 30 percent increased relative risk.
Children who were exposed to tobacco smoke during pregnancy and second-hand smoke at 4 months had 2.4 times increased relative risk.
