CINCINNATI, March 29 (UPI) -- Girls appear to suffer more than boys from the effects of secondhand smoke, a study by the University of Cincinnati College of Medicine found.
First author Kelly Brunst, a doctoral candidate in the University of Cincinnati's division of epidemiology and biostatistics, said differential gender effects of secondhand smoke exposure was detected using an internal biomarker for secondhand smoke -- hair cotinine, a product of nicotine metabolism.
