THURSDAY, Aug. 8 (HealthDay News) -- Children with asthma who
are exposed to secondhand smoke have more severe symptoms and more
frequent outbreaks than other kids with asthma.
Yet despite these health hazards, the rate of asthmatic children
who regularly breathe in secondhand smoke hasn't changed since
1999, according to the U.S. Centers for Disease Control and
From 1999 to 2010, the percentage of children without asthma
exposed to environmental tobacco smoke decreased from about 57
percent to 44 percent, according to the research team lead by Dr.
Kenneth Quinto at the CDC's National Center for Health
Exposure of children with asthma showed no change, however, with
nearly 58 percent exposed to environmental tobacco smoke from 1999
to 2002 and 54 percent exposed from 2007 to 2010, which isn't a
significant difference, Quinto said.
"The message isn't getting through to parents who smoke," Quinto said, adding that more needs to be done to ensure that parents of children with asthma are not exposing them to secondhand smoke.
Not only is secondhand smoke bad for children with asthma, but
exposure to secondhand smoke can lead to developing asthma, Quinto
The CDC researchers used data from the National Health and
Nutrition Examination Survey spanning from 1999 to 2010 to come to
From 2007 to 2010, more girls with asthma (nearly 58 percent)
were exposed to secondhand smoke than girls without asthma (44
percent), the study also found. However, there was no significant
difference among boys.
During this period, Mexican-American children, kids aged 6 to 11
and poor kids with asthma were all more likely to be living with
secondhand smoke, the researchers found.
One expert said the new findings weren't very surprising.
"Children with asthma are often in environments with secondhand smoke," said Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City. "We also know that secondhand smoke leads to asthma in childhood."
The answer, Horovitz said, is for parents to stop smoking.
"Smoking is the cause of these problems -- cessation can reduce
them," he said.
One antismoking advocate called for more sweeping solutions.
"These results underscore the need for every state and community to enact comprehensive smoke-free laws that include all workplaces and public places," said Vince Willmore, vice president for communications at the Campaign for Tobacco-Free Kids. He said that to date, 30 states and Washington, D.C., have passed laws requiring smoke-free restaurants and bars.
"For parents who smoke, the best step to protect children is to quit smoking," Willmore said. "Parents should also ensure that homes, cars and other places frequented by children are smoke-free."
