If Alcohol Policies Were a Newly Discovered Vaccine, We Would Spend Billions Disseminating It

A senior author on the study, Dr. Timothy Naimi was once quoted saying “If alcohol policies were a newly discovered gene, pill or vaccine, we’d be investing billions of dollars to bring them to market”

Instead of expanding and implementing current alcohol policies to reduce potential morbidity and mortality due to binge drinking in the United States, politicians and researchers typically call only for new prevention and treatment strategies when there is a potent prevention tool already available.

Binge drinking accounts for roughly half of alcohol-attributable deaths in the U.S.

Alcohol policies have been shown to reduce excessive alcohol consumption and other related problems, however, it has been challenging to examine individual state-level policies because the number and scope of existing alcohol policies.

Xuan and colleagues developed the Alcohol Policy Scale (APS) in order to measure and evaluate the impact of alcohol policy across states between 2005 and 2011.

The APS was developed by surveying a panel of ten experts in the field who identified alcohol policies for inclusion; 29 policies were included in the final scale. Each policy was rated by a 5-point Likert scale and examined both the efficacy and the impact of the policy. A higher APS score indicated that a mix of more effective policies were associated with a lower state-level prevalence of binge drinking.

Authors compared different types of policies and looked more closely at policies targeting the entire population, policies targeting underage drinking, consumption-oriented policies that regulated alcohol production or sales, and consumption policies were also compared with impaired driving policies. The authors utilized the Behavioral Risk Factor Surveillance Survey (BRFSS), a randomized telephone survey that includes adults age 18 and older to evaluate binge drinking rates.

Included in the analysis were 2,397,742 adults. Fourteen percent of these reported binge drinking, defined as 5 or more drinks within a drinking episode (4 or more for women) at least once in the past 30 days, 3.4% reported 5 or more binge drinking episodes and an additional 3.7% of respondents reported consuming a maximum of 10 or more drinks during a drinking occasion during the past 30 days. Authors found that even when accounting for demographics such as age, race/ethnicity, and gender, a 10 percentage point increase in the APS score was associated with a significantly decreased likelihood of binge drinking, frequent binge drinking, and consuming 10 or more drinks at a drinking occasion.

The relationship between APS score and binge drinking outcome did not differ by age or gender, however, differences were found by race/ethnicity.

Non-Hispanic Whites and non-Hispanic others were found to have significantly decreased odds of binge drinking compared to Hispanics.

This suggests that alcohol policies may have a greater effect on non-Hispanic Whites and non-Hispanic others.

Policies targeting the general population were found to have the largest independent relationship with binge drinking compared to policies targeting youth, along with policies that target alcohol consumption versus impaired driving.

Policies that either increased the cost of alcohol or reduced availability also has the largest impact compared to other types of policies. The authors found that the greatest impact related to alcohol policies was accounted for by a small number of individual policies including a combined policy that targeted taxes and reducing outlet density.

IN CONTEXT

Research at state and federal alcohol policy levels can help to provide a more comprehensive view of how alcohol policies impact alcohol use. In fact, results from research on state and federal alcohol policies adds additional information over and above that stemming from community-level factors.

By further examining systemic factors including social support and mutual-help, community variables, and other environmental factors, it may be possible to learn how to better use state and federal-level alcohol policies.
