Previously, prenatal smoking has been linked to negative consequences in children of all ages, including premature birth, low weight or underdevelopment and asthma. Now, a connection also has been made between smoking while pregnant and hearing loss in adolescents, according to a new study published in the journal JAMA Otolaryngology.
"Cigarette smoking is probably the worst man-made epidemic," says Michael Weitzman, study author and a professor at the New York University School of Medicine.
In a group of 964 kids ranging in age from 12 to 15 from the National Health and Nutrition Examination Survey in 2005-2006, about 16% of parents confirmed prenatal smoke exposure. In most cases, kids with exposure were roughly three times more likely to have mild hearing loss. Kids without exposure also were found to hear better by three decibels in comparison with those who were exposed.
