Surveillance of alcohol use through population surveys in the Americas from 2010 to 2019

The aims of this study were to identify alcohol-related population surveys administered in the Americas, determine which alcohol-related measures are examined and identify coverage gaps regarding alcohol-related measures.

As part of the Global Information System on Alcohol and Health study, a systematic search was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to identify regionally or nationally representative survey reports of the general population from 1 January 2010 to 6 August 2019. Alcohol-related measures extracted from surveys were categorized into 10 domains: alcohol consumption status; alcohol consumption; unrecorded alcohol consumption; drinking patterns; symptoms of dependence and/or harmful use; drinking during pregnancy; treatment coverage; second-hand harms; economic; and other.

The systematic search identified 7417 survey reports, 94 of which were new and included in this study, with an additional 11 studies included from a previous systematic study of alcohol surveys. In total, 94 unique surveys and 161 unique survey waves were located, representing 105 unique survey questionnaires covering 30 countries. No population surveys were found for five member states; namely, Antigua and Barbuda, Dominica, Haiti, Saint Vincent and the Grenadines and Saint Kitts and Nevis. All countries with population-based alcohol surveys had had a population survey probing alcohol use in the past year/month. Questions regarding heavy episodic drinking, alcohol use disorders, treatment-seeking for alcohol use, drinking during pregnancy, harms to others and the amounts spent on alcohol were asked in 26, 25, 10, 6, 22 and 11 countries, respectively.

The heterogeneity in alcohol-related population surveys in the Americas from 2010 to 2019 limits their comparability throughout countries and over time. Future surveys should implement a standardized set of core questions to provide consistency in the monitoring of alcohol consumption and alcohol-related harms.
