Global alcohol exposure between 1990 and 2017 and forecasts until 2030: a modelling study

BACKGROUND: Alcohol use is a leading risk factor for global disease burden, and data on alcohol exposure are crucial to evaluate progress in achieving global non-communicable disease goals. We present estimates on the main indicators of alcohol exposure for 189 countries from 1990-2017, with forecasts up to 2030.

METHODS: Adult alcohol per-capita consumption (the consumption in L of pure alcohol per adult [>/=15 years]) in a given year was based on country-validated data up to 2016. Forecasts up to 2030 were obtained from multivariate log-normal mixture Poisson distribution models. Using survey data from 149 countries, prevalence of lifetime abstinence and current drinking was obtained from Dirichlet regressions. The prevalence of heavy episodic drinking (30-day prevalence of at least one occasion of 60 g of pure alcohol intake among current drinkers) was estimated with fractional response regressions using survey data from 118 countries.

FINDINGS: Between 1990 and 2017, global adult per-capita consumption increased from 5.9 L (95% CI 5.8-6.1) to 6.5 L (6.0-6.9), and is forecasted to reach 7.6 L (6.5-10.2) by 2030. Globally, the prevalence of lifetime abstinence decreased from 46% (42-49) in 1990 to 43% (40-46) in 2017, albeit this was not a significant reduction, while the prevalence of current drinking increased from 45% (41-48) in 1990 to 47% (44-50) in 2017. We forecast both trends to continue, with abstinence decreasing to 40% (37-44) by 2030 (annualised 0.2% decrease) and the proportion of current drinkers increasing to 50% (46-53) by 2030 (annualised 0.2% increase). In 2017, 20% (17-24) of adults were heavy episodic drinkers (compared with 1990 when it was estimated at 18.5% [15.3-21.6%], and this prevalence is expected to increase to 23% (19-27) in 2030.

INTERPRETATION: Based on these data, global goals for reducing the harmful use of alcohol are unlikely to be achieved, and known effective and cost-effective policy measures should be implemented to reduce alcohol exposure.
