NHANES includes a home interview, physical examination at a mobile examination center where biologic specimens are collected, and laboratory specimen testing, including serum cotinine analysis, for participants aged ≥3 SHS exposure was assessed using serum cotinine, a metabolite of nicotine that reflects recent exposure (4,6).You may find best people out there and can make plenty of new friends. uses cookies to improve performance by remembering your session ID when you navigate from page to page.During 2011–2012, SHS was highest among: children aged 3–11 years (40.6%), non-Hispanic blacks (46.8%), persons living below the poverty level (43.2%), and persons living in rental housing (36.8%).
