NYU: Cigarette Smoking Prevalence in Young Adults

A piece co-authored by Dr. Jennifer Cantrell, assistant professor of social and behavioral sciences at New York University College of Global Public Health, was published by PLOS ONE titled “Examining differences in cigarette smoking prevalence among young adults across national surveillance surveys.”

Accurate smoking prevalence data is critical for monitoring, surveillance, and evaluation. However, estimates of prevalence vary across surveys due to various factors. This study examines smoking prevalence estimates for 18–21 year olds across six U.S. national telephone, online and in-person surveys for the years 2013 and 2014. 

Results indicate that estimates of ever smoking ranged from 35 percent to 55 percent, while current smoking ranged from 16 percent to 30 percent. Across the three modalities, household surveys were found to yield the highest estimates of smoking prevalence among 18 to 21 year olds while online surveys yielded the lowest estimates, and this was consistent when stratifying by gender and race/ethnicity. Assessments of the joint effect of gender, race/ethnicity, educational attainment and survey mode indicated that the relative differences in the likelihood of smoking were consistent across modes for gender and education groups. However, the relative likelihood of smoking among minority groups compared with non-Hispanic Whites varied across modes.

Over and underrepresentation of certain demographic subpopulations, variations in survey question wording, and social desirability effects may explain modality differences in smoking estimates. Thus, further research is needed to evaluate the effect of survey mode on variation in smoking prevalence estimates across national surveys, particularly for young adult populations.
