Abstract
U.S. General Educational Development diploma (GED) recipients have the highest smoking prevalence of any education level. This paper describes demographic characteristics and tobacco use patterns and examines effect modification and confounding as potential explanations for higher crude prevalence of smoking. METHODS: The study population included adults aged 25 and older in the 2013 National Health Interview Survey. We estimated adjusted prevalence ratios and 95% CIs for smoking and quitting behaviors using weighted multivariable logistic regression. RESULTS: Among women with a GED, adjusted prevalence of ever use (58.7%) and smoking (32.4%) was 1.50 and 1.52 times the prevalence among high school dropouts (39.1%, 21.3%). Female GED recipients had a significantly higher prevalence of ever smoking compared with dropouts. We found no significant educational differences in smoking prevalence among men or quit behaviors for either sex. CONCLUSIONS: More research is needed to identify targeted interventions to prevent smoking in this disparate population.
