Periodontitis affects approximately 47% of adults in the United States and the U.S. Surgeon General has concluded that cigarette smoking is one of its causes. Despite numerous adverse health effects of environmental tobacco smoke (ETS), an association between periodontitis and this "second-hand smoke" in non-smokers remains questionable. In this study, the researchers aimed to investigate the association between serum cotinine and periodontitis among U.S. non-smokers.
Researcher Aderonke A. Akinkugbe of the University of North Carolina at Chapel Hill, recently presented a study at the 93rd General Session and Exhibition of the International Association for Dental Research titled Environmental Tobacco Smoke Is Associated With Periodontitis In U.S. Non-Smokers. Data for this cross-sectional analysis was derived from 3,255 self-reported lifetime non-smokers who participated in the 2009-2012 National Health and Nutrition Examination Survey, underwent periodontal examination and provided blood samples.
Serum cotinine, a metabolite of nicotine, was used to classify participants as exposed to ETS when its concentration was between 0.015mg/ml (the lower detection limit of the assay) and 3ng/ml. Participants with >3ng/ml were excluded because it suggests misreporting of smoking or exposure to smokeless tobacco. Moderate/Severe periodontitis was defined as the presence of >=2 interproximal sites with attachment loss of >=4mm OR >=2 interproximal sites with probing pocket depth of >=5mm. Odds ratios (OR) and 95% confidence limits (95%CL) were estimated using logistic regression models for survey data. Potential effect measure modification was evaluated and models adjusted for confounding effects of age, gender, race/ethnicity, diabetes, income and education.
The percentage (95%CL) of nonsmokers with serum cotinine levels >=0.015ng/ml was 57.4% (54.5, 60.3) and 31% (28.1, 33.9) had moderate/severe periodontitis. The unadjusted odds of moderate/severe periodontitis was 62% higher [OR(95%CL)=1.62(1.32, 1.98)] among the exposed compared to the unexposed. There was no significant effect modification by race/ethnicity (p >0.9). In the fully adjusted analysis, nonsmokers exposed to ETS had 1.45 times the odds of moderate/severe periodontitis as unexposed nonsmokers [OR(95%CL)=1.45(1.18, 1.77)]. ETS exposure was significantly associated with greater odds of moderate/severe periodontitis among adult U.S nonsmokers.
