Population risks of alcohol consumption by quantity, geography, age, sex and year: a systematic analysis for the study of the global burden of disease 2020

Summary

Fund

The health risks associated with moderate alcohol consumption continue to be debated. Small amounts of alcohol may reduce the risk of some health outcomes, but increase the risk of others, suggesting that the overall risk depends, in part, on the rates of underlying disease, which vary by region, age, sex and year.

Methods

For this analysis, we constructed load-weighted dose-response relative risk curves across 22 health outcomes to estimate the level of theoretical minimum risk exposure (TMREL) and non-drinker equivalence (NDE), the level of consumption at which the risk to health is equivalent to that of a non-drinker, using the disease rates of the Study of the Global Burden of Disease, Injury and Risk Factors (GBD) 2020 for 21 regions , including 204 countries and territories, by age group of 5 years, sex and year for people. from 15 to 95 years and older from 1990 to 2020. From the ECM, we quantified the population that consumed harmful amounts of alcohol.

Discoveries

Load-weighted relative risk curves for alcohol consumption varied by region and age. Among people aged 15 to 39 in 2020, the TMREL ranged from 0 (95% uncertainty range 0-0) to 0.603 (0.400-1.00) standard drinks per day, and the NDE ranged from 0.002 (0–0) and 1 · 75 (0 · 698–4 · 30) standard drinks per day. Among people 40 years of age or older, the load-weighted relative risk curve was J-shaped for all regions, with a 2020 TMREL ranging from 0.114 (0-0.403) to 1.87 (0.500-3). ). · 30) standard drinks per day and an ECM ranging from 0 · 193 (0–0 · 900) to 6 · 94 (3 · 40–8 · 30) standard drinks per day. Among people who consumed harmful amounts of alcohol in 2020, 59.1% (54.3–65.4) were between 15 and 39 years old and 76.9% (73.0–81.3) were men.

Interpretation

There is solid evidence supporting alcohol consumption recommendations that vary by age and location. Stronger interventions are needed, especially those tailored to younger people, to reduce the substantial overall health loss attributable to alcohol.

Introduction

Alcohol consumption accounted for 1.78 million (95% uncertainty range. [UI] 1 · 39–2 · 27) deaths in 2020 and was the leading risk factor for mortality among men aged 15–49 years (Bryazka D, unpublished). The relationship between moderate alcohol consumption and health is complex, as demonstrated by multiple previous studies.1
