The results obtained after the researchers followed 1,000 children aged 12-15 years in 2005-2006 in the U.S. National Health Examination Survey. Approximately 16 percent of adolescents exposed to cigarette smoke exposure is known while still in the womb.
Research shows evidence that fetal exposure to cigarette smoke have a three times greater risk for experiencing deafness one ear or have bad hearing compared with the fetus that was never exposed to smoke. Even so the study could not show evidence of a causal relationship between smoking during pregnancy with hearing problems in infants.
"However, the increased risk tripled in adolescents exposed to secondhand smoke while still in the womb is certainly alarming," said lead researcher Dr. Michael Weitzman at NYU School of Medicine in New York City, as reported by U.S. News.
It is also approved by Dr. Martin Chavez of Maternal Fetal Medicine at Winthrop University Hospital, New York. According to Chavez, exposure to toxins on the fetus can provide long-term consequences. This study provides evidence that pregnant women should quit smoking or stay away from cigarette smoke.
