Alcohol consumption, long acknowledged as a significant risk factor for death and disability, unveils a complex relationship with health, according to the latest findings from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016. The study, offering a comprehensive examination of health accounting across 195 locations from 1990 to 2016, challenges previous perceptions by considering the potential protective effects of moderate alcohol consumption on certain health conditions.
A Comprehensive Approach to Health Analysis
Employing a meticulous methodology, the study drew on 694 data sources, encompassing individual and population-level alcohol consumption, and analyzed 592 prospective and retrospective studies on alcohol use risk. Notable improvements over previous estimates included adjustments for tourist and unrecorded consumption, a new meta-analysis of relative risks for 23 health outcomes associated with alcohol use, and the development of a novel method to determine the level of alcohol consumption that minimizes overall health risks.
Global Impact of Alcohol Use
Globally, alcohol use emerged as the seventh leading risk factor for both deaths and disability-adjusted life-years (DALYs) in 2016. It accounted for 2.2% of age-standardized female deaths and a staggering 6.8% of age-standardized male deaths. Among the population aged 15–49 years, alcohol use took the forefront as the leading risk factor, contributing to 3.8% of female deaths and a striking 12.2% of male deaths in 2016.
For this age group, alcohol-attributable DALYs were 2.3% for females and 8.9% for males. Leading causes of attributable deaths in this demographic included tuberculosis, road injuries, and self-harm. Cancers played a substantial role in alcohol-attributable deaths for those aged 50 years and older, constituting a significant portion of total alcohol-related fatalities.
Zero Tolerance for Minimizing Health Risks
Perhaps the most striking revelation is that the level of alcohol consumption that minimizes harm across health outcomes is zero standard drinks per week. The study found that the risk of all-cause mortality, particularly cancers, increases with escalating levels of consumption.
Policy Implications and Urgent Call for Action
The study’s results suggest a critical need for the global reassessment of alcohol control policies, emphasizing the necessity to lower overall population-level consumption. With alcohol use identified as a leading risk factor for the global disease burden and a substantial contributor to health loss, the findings advocate for swift and decisive policy changes to address the pervasive impact of alcohol on public health. The study concludes that zero tolerance might be the key to minimizing the alarming health risks associated with alcohol consumption.
WHO statement
Based on this study, The World Health Organization has now published a statement when it comes to alcohol consumption, there is no safe amount that does not affect health.
