Recent Trends In Exposure To Secondhand Smoke In The United States Population, Chieh-I Chen, Tanya Burton, Christine L. Baker, Vera Mastey, David M. Mannino

David M. Mannino

Background Previous research using the National Health and Nutrition Examination Surveys (NHANES) data documented a significant downward trend in secondhand smoke (SHS) exposure between 1988 and 2002. The objective of this study was to assess whether the downward trend in exposure continued from 2001 through 2006.

Methods We analyzed data from the 2001-2006 NHANES to estimate exposure of nonsmokers to SHS. Geometric means of serum cotinine levels for all nonsmokers were computed.

Results Overall serum cotinine levels (95% Confidence Intervals) in 2001-2002, 2003-2004, and 2005-2006 were 0.06 ng/mL (0.05-0.07), 0.07 ng/mL (0.06-0.09), and 0.05 ng/mL (0.05-0.06), respectively. Subgroup analysis by …

Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton

David M. Mannino

This study investigated gender differences in the perceived “pros” and “cons” of smoking using the constructs of decisional balance (DB) and stage of change from the Transtheoretical Model. The population distribution for stage of change among a population-based, cross-sectional survey of 155 current smokers over 40 years was: precontemplation (22.6%), contemplation (41.9%), preparation (35.5%). Results of stepwise regression models indicated significant gender differences in DB were in the preparation stage of change; scores on the DB measure increased 3.94 points (95% CI: 1.94, 5.93) for male smokers. Interventions targeting the “pros” and “cons” of smoking may need to be gender …

Active And Passive Smoking And Blood Lead Levels In U.S. Adults: Data From The Third National Health And Nutrition Examination Survey, David M. Mannino, David M. Homa, Thomas Matte, Mauricio Hernandez-Avila

David M. Mannino

Lead is a component of tobacco and tobacco smoke. We examined the relationship between current, former, and passive smoking and blood lead levels in a nationally representative sample of 16,458 U.S. adults, aged 17 years or older, who participated in the Third National Health and Nutrition Examination Survey (1988–1994). We used linear and logistic regression modeling, adjusting for known covariates, to determine the relationship between smoking and blood lead levels. Geometric mean blood lead levels were 1.8 μg/dl, 2.1 μg/dl, and 2.3 μg/dl in never-smokers with no, low, and high cotinine levels, respectively. Levels were 2.9 μg/dl in former smokers …

Tobacco Smoke Exposure And Decreased Serum And Red Blood Cell Folate Levels: Data From The Third National Health And Nutrition Examination Survey, David M. Mannino, Joseph Mulinare, Earl S. Ford, Joel Schwartz

David M. Mannino

The aim of this cross-sectional study was to determine the effects of smoke exposure on serum and red blood cell folate levels. Data collected as part of the Third National Health and Nutrition Examination Survey were analyzed. Serum and red blood cell folate levels were measured in active smokers and nonsmokers with high, moderate, and low exposure to environmental tobacco smoke. After adjusting for dietary intake of folate and other covariates, we found that both smokers and nonsmokers with high smoke exposure had lower red blood cell folate levels than did nonsmokers with low smoke exposure (−86 nmol/l [95% confidence …
