Serum metalloproteinase and urinary cotinine level in smokeless tobacco chewers

Validation of self-reported smokeless tobacco use by measurement of serum cotinine concentration among US adults.

Although investigators have assessed the relationship between self-reported cigarette smoking and biomarker levels, the validity of self-reported information on smokeless tobacco (SLT) use is uncertain. We used aggregated data from the 2003-2004, 2005-2006, 2007-2008, and 2009-2010 administrations of the National Health and Nutrition Examination Survey (NHANES) to compare self-reported SLT use ...
