THURSDAY, Aug. 8 (HealthDay News) -- From 1999 to 2010, environmental tobacco smoke (ETS) exposure decreased for children without asthma, but did not change among children with asthma, according to a report published online Aug. 8 by the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS).
Kenneth B. Quinto, M.D., M.P.H., and colleagues from the NHCS in Hyattsville, Md., used data from the National Health and Nutrition Examination Survey to present trends in ETS exposure in children with and without asthma from 1999 to 2010. Differences by sex, race and ethnicity, income, and age group were described for 2007 to 2010.
The researchers found that the percentage of children without asthma exposed to ETS decreased from 57.3 percent in 1999 to 44.2 percent in 2010, while no change was seen for children with asthma, with 57.9 and 54.0 percent exposed to ETS in 1999 to 2002 and 2007 to 2010, respectively. The percentage of children with asthma who were exposed to ETS was higher than children without asthma in 2007 to 2010. Children with asthma who were girls, Mexican-American, aged 6 to 11 years, or had family income below 350 percent of the federal poverty guidelines were more likely to be exposed to ETS in 2007 to 2010.
"ETS exposure among children with asthma was higher (54.0 percent) than for those without asthma (44.2 percent) in 2007 to 2010," the authors write.
