Recently we have talked about the adverse affects of secondhand smoke on non-smokers. The University of Cincinnati has conducted a study on secondhand smoke among young children. The research examined 476 children and found that those who were exposed to high levels of secondhand smoke and had allergic sensitizations at the age of 2 were at higher risk of decreased lung function at age 7. It was also noticed that in this group, young girls experienced side-effects six times worse than young boys. The exact reason for why girls are more susceptible to side-effects is unknown, but is hypothesized that it is "ultimately dependent on the timing of exposure as well as the child's 'total load' in relationship to cumulative risk factors -- exposures, allergic sensitization, asthma status, genetic susceptibility and sex hormones."
