TUESDAY, Nov. 9 (HealthDay News) -- Tobacco carcinogens were
found in the urine of 90 percent of children who lived in a home
where at least one parent smoked, a new study has found.
The analysis of urine samples from 79 U.S. children aged 1 month
to 10 years also found that the average level of tobacco
carcinogens in the children was about 8 percent of the level found
"This finding is striking, because while all of the researchers involved in this study expected some level of exposure to carcinogens, the average levels were higher than what we anticipated," lead researcher Janet L. Thomas, an assistant professor of behavioral medicine at the University of Minnesota, said in an American Association for Cancer Research (AACR) news release.
She noted that levels of carcinogens found in the urine of adult
nonsmokers who are exposed to secondhand smoke are 1 to 5 percent
that of smokers.
"No one knows the long-term impact of cumulative exposure to these chemicals. It could prime the body in some way that leads to DNA changes in cells that might contribute to lung damage, and potentially lung cancer," Thomas said.
Among the other findings:
"Almost one-third of young children in the United States live in a house with at least one smoker. My concern is that parents and family members may not truly understand the risk they pose to these children," Thomas said.
The study was scheduled to be presented at this week's AACR
Frontiers in Cancer Prevention Research Conference, held in
The U.S. Centers for Disease Control and Prevention has more
children and secondhand smoke.
