"When thinking about cancer risk and cancer prevention, the focus tends to be on individual-level risk factors rather than environmental determinants of cancer, like public policies that affect the consumption of alcohol or tobacco," said study co-author Dr. Timothy Naimi.
Naimi is a physician and researcher at Boston Medical Center and Boston University School of Public Health.
For the new study, the researchers analyzed data on cancer deaths per state from 2006 to 2010. They gave each state an alcohol policy score based on 29 regulations, such as alcohol taxes and restrictions on the number of locations allowed to sell booze.
For all cancers combined, more restrictive alcohol policies were associated with a reduced risk of cancer death. A 10% increase in the strength of alcohol policies was associated with an 8.5% decrease in cancer deaths, the findings showed.
The results were similar among men and women. They highlight the potential impact that public health policies can have on preventing cancers at the population level, according to the study authors. The findings were published online recently in the journal Chemico-Biological Interactions.
