I used data from the 1999 through 2010 National Health and Nutrition Examination Survey (NHANES),3 a nationally representative health survey of the US civilian noninstitutionalized population conducted by the National Center for Health Statistics. It includes a health interview as well as a physical examination and collection of biospecimens. Approximately 10 000 individuals participate in the NHANES every 2 years. I analyzed data for NHANES current smokers 20 years and older using logistic regression analysis to examine the association between having been diagnosed with a stroke by a health professional and menthol smoking. I included pack years of smoking, sex, age, race and ethnicity (using the NHANES race and ethnicity categories), educational attainment, ratio of family income to poverty threshold, use of other tobacco products, and body mass index as control variables in the analysis. Of the 7055 NHANES participants who reported that they were current smokers, 5745 had information for all regression variables, including menthol cigarette use (600 smokers did not have family income information and 294 were missing menthol information). In total, 1765 smokers were identified as menthol smokers and 3980 as nonmenthol smokers. Of these smokers, 195 reported having had a stroke. Stroke prevalence was 3.4% (95% CI, 2.9%-4.0%) among nonmenthol smokers and 3.3% (95% CI, 2.6%-4.3%) among menthol smokers. Stroke prevalence was similar among all NHANES smokers at 3.5% (95% CI, 3.0%-4.1%) for nonmenthol smokers and 3.8% (95% CI, 3.0%-4.7%) for menthol smokers. I conducted the analyses using the appropriate NHANES sample weights, taking into account the NHANES complex sample design.
