Abstract
Purpose
There are limited data on the burden of cancer attributable to cigarette smoking by metropolitan areas to inform local tobacco control policies in the USA. We estimated the proportion of cancer deaths attributable to cigarette smoking (or population attributable fraction [PAF]) in 152 U.S. metropolitan or micropolitan statistical areas (MMSAs).
Methods
Smoking-related PAFs for cancer mortality in ages ≥ 30 years in 2013–2017 were estimated using cross-sectional age-, sex-, and MMSA-specific cigarette smoking prevalence and cancer mortality data obtained from the Behavioral Risk Factor Surveillance System and the U.S. Cancer Statistics Database, respectively.
Results
Overall smoking-related PAFs of cancer ranged from 8.8% (95% CI, 6.3–11.9%) to 35.7% (33.3–37.9%); MMSAs with the highest PAFs were in the South region and Appalachia. PAFs also substantially varied across MMSAs within regions or states. In the Northeast, for example, the PAF ranged from 24.2% (23.7–24.7%) to 33.7% (31.3–36.2%).
Conclusion
The proportion of cancer deaths attributable to cigarette smoking is considerable in each MMSA, with as many as 4 in 10 cancer deaths attributable to smoking in the South region and Appalachia. Broad and equitable implementation and enforcement of proven tobacco control interventions at all government levels could avert many cancer deaths across the USA.
Data availability
The data that support the findings of this study are available from the Behavioral Risk Factor Surveillance System (reference number 10) and U.S. Cancer Statistics Public Use database (reference number 11).
