Unrecorded alcohol consumption in Lithuania: a modelling study for 2000-2021

The aim of the study was to estimate unrecorded alcohol consumption in Lithuania for the period 2000-2021 using an indirect method for modelling consumption based on official consumption data and indicators of alcohol-related harm. Methodology employed for estimating the unrecorded alcohol consumption was proposed by Norstrom and was based on the country's 2019 European Health Interview Survey and indicators of fully alcohol-attributable mortality. The proportion of unrecorded alcohol consumption was estimated as 8.30% (95% CI 7.7-8.9%) for 2019 in Lithuania. The estimated total (recorded and unrecorded) alcohol per capita consumption among individuals 15 years of age and older in 2019 was 12.2 L of pure alcohol, 1.01 (95% CI 0.94-1.09%) L of which is likely unrecorded. The lowest unrecorded alcohol level was estimated for 2009 and 2014, while 2018 had the highest level (i.e. 9.33% of total alcohol per capita consumption). Unrecorded alcohol consumption in Lithuania is likely to be modest when compared to recorded alcohol consumption, the latter of which still remains a major challenge to public health. Short Summary: This paper presents estimates of unrecorded alcohol consumption in Lithuania, based on historical series and on data from the 2019 European Health Interview Survey. Unrecorded alcohol consumption in Lithuania is likely to be relatively modest, suggesting that recorded alcohol consumption remains by far the major contributor to alcohol-attributable harm in Lithuania.
