Abstract
BACKGROUND: Previous research has shown that long or slim cigarette design can mitigate perception of harmfulness. Cadmium (Cd) is a toxicant in cigarettes and is associated with adverse outcomes. We assessed the relationship between cigarette rod length/circumference and blood Cd levels among U.S. smokers using data from the 1999-2010 National Health and Nutrition Examination Survey. METHODS: The analyses were performed on 4486 current cigarette smokers aged ≥20years old. Cigarette rod length included regular (68-72mm), king (79-88mm), long (94-101mm), and ultra-long (110-121mm) cigarettes currently smoked. Overall and gender stratified multivariate linear regression analyses were performed, adjusting for other influential covariates. RESULTS: Gender stratified analysis indicated that female smokers of long and ultra-long cigarette had 20% and 27% higher mean Cd levels compared to smokers of regular sized cigarettes respectively, despite the fact that all the ultra-long cigarettes were slim cigarettes. Furthermore, among females, slim cigarette users did not reduce blood cadmium levels compared to non-slim users. CONCLUSIONS: Female smokers of long or ultra-long cigarettes had higher mean blood Cd levels compared to smokers of regular cigarettes independent of slim design. Further research into this association is warranted.
