Cigar smoking prevalence and morbidity among US adults, 2000-2015.

ABSTRACT

Cigar smoking causes many of the same health conditions as cigarettes, but less information is available on prevalence of use trends and the disease burden of cigar smoking in the US. To examine these issues, we analyzed cigar use and health condition data from the National Health Interview Survey from 2000, 2005, 2010, and 2015, estimating prevalence of use by year and over time. We also estimated the number of, and adjusted disease prevalence ratios for, US adults aged ≥35 years with self-reported history of heart disease, stroke, or cancer attributable to cigar smoking. We found that prevalence of current cigar smoking has remained generally stable at around 2.3% among US adults aged ≥18 years between 2000 and 2015 but has increased among female and non-Hispanic black adults. Former exclusive cigar smokers were more likely to report having had heart conditions (aPR = 1.33, 95% CI = 1.03-1.72), stroke (aPR = 2.42, 95% CI = 1.57-3.75), and cancer (aPR = 1.44, 95% CI = 1.09-1.88) than never cigar smokers. It is estimated that nearly 200,000 cardiovascular conditions and cancer cases among US adults are attributable to former exclusive cigar smoking. This analysis shows that prevalence of current cigar smoking has remained stable among US adults but has increased among certain demographic groups. Former exclusive cigar use is associated with increased prevalence of heart disease, stroke, and cancer, which may result in part from smoking cessation following disease onset.
