The global proportion and volume of unrecorded alcohol in 2015

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 Norström 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.

Unrecorded alcohol use in 33 European countries: Analyses of a comparative survey with 49,000 people who use alcohol

BACKGROUND

Using data from 33 European countries (including all EU member states), this study aimed to 1) estimate the prevalence of unrecorded alcohol use among past-week alcohol users, 2) describe how unrecorded alcohol use is associated with drinking patterns, and 3) estimate the contribution of unrecorded alcohol to the total amount of alcohol consumed annually in these countries.

METHODS

Data from 25,728 adults who drank alcohol in the past week and self-reported their use of unrecorded alcohol in 2021 were analysed. Prevalence of unrecorded alcohol use in the last week was estimated for those with low, medium, and high risk drinking categorised using the WHO-recommended risk thresholds and definition of risky single occasion drinking. Prevalence estimates were weighted for the country-specific gender, age, and geographical population distribution. An adjusted weighted proportion of unrecorded drinking occasions in total drinking occasions was calculated and compared to 2020 recorded annual per capita consumption estimates.

RESULTS

Among past-week alcohol users, the average prevalence of past-week unrecorded alcohol use was 12.1% (95% CI: 11.7-12.5%), with considerable difference between countries (min: 2.0% in Malta; max: 27.0% in Greece). Unrecorded alcohol use was much more prevalent among people with high-risk alcohol use in the past week (24.2%, 95% confidence interval [CI]: 22.9-25.5%) compared to people with low- (6.5, 95% CI: 6.0-6.9%) or medium-risk alcohol intake in the past week (13.6%, 95% CI: 12.9-14.3%). Unrecorded alcohol accounted for 7% of per capita consumption in 2020.

CONCLUSIONS

This is the first comparable assessment of unrecorded alcohol use across EU and affiliated countries. The findings add support to the observation that availability of unrecorded alcohol may contribute to risky drinking in Europe. The observed country variations may be related to differences in country-specific pricing policies and measures to reduce the production and consumption of unrecorded alcoholic beverages.

Capturing Russian drinking patterns with the Alcohol Use Disorders Identification Test: An exploratory interview study in primary healthcare and narcology centers in Moscow

BACKGROUND

Despite a considerable reduction in alcohol consumption, Russia has one of the highest levels of alcohol-attributable burden of disease worldwide due to heavy episodic drinking patterns. Further improvement of alcohol control measures, including early provision of screening and brief interventions (SBI), is needed. The legislative framework for delivering SBI in Russia was introduced in 2013. As part of the creation and validation of a Russian version of the Alcohol Use Disorders Identification Test (AUDIT), the present contribution explored challenges in using the AUDIT in Russia to inform a subsequent validation study of the tool.

METHODS

Qualitative in-depth expert interviews with patients and healthcare professionals from four primary healthcare and narcology facilities in Moscow. A total of 25 patients were interviewed, 9 from a preventive medicine hospital, 8 from a polyclinic, and 9 from narcology clinics. Also, 12 healthcare professionals were interviewed, 5 of whom were primary healthcare doctors and 7 were narcologists.

RESULTS

Patients and healthcare professionals expressed difficulties in dealing with the concept of a "standard drink" in the AUDIT, which is not used in Russia. Various patients struggled with understanding the meaning of "one drinking occasion" on the test, mainly because Russian drinking patterns center around festivities and special occasions with prolonged alcohol intake. Narcology patients had specific difficulties because many of them experienced zapoi-a dynamic drinking pattern with heavy use and a withdrawal from social life, followed by prolonged periods of abstinence. Surrogate alcohol use was described as a common marker of alcohol dependence in Russia, not accounted for in the AUDIT.

CONCLUSIONS

The provided analyses on the perception of the Russian AUDIT in different patient and professional groups suggest that a series of amendments in the test should be considered to capture the specific drinking pattern and its potential harms.

The socioeconomic gradient of alcohol use: an analysis of nationally representative survey data from 55 low-income and middle-income countries

BACKGROUND

Alcohol is a leading risk factor for over 200 conditions and an important contributor to socioeconomic health inequalities. However, little is known about the associations between individuals' socioeconomic circumstances and alcohol consumption, especially heavy episodic drinking (HED; ≥5 drinks on one occasion) in low-income or middle-income countries. We investigated the association between individual and household level socioeconomic status, and alcohol drinking habits in these settings.

METHODS

In this pooled analysis of individual-level data, we used available nationally representative surveys-mainly WHO Stepwise Approach to Surveillance surveys-conducted in 55 low-income and middle-income countries between 2005 and 2017 reporting on alcohol use. Surveys from participants aged 15 years or older were included. Logistic regression models controlling for age, country, and survey year stratified by sex and country income groups were used to investigate associations between two indicators of socioeconomic status (individual educational attainment and household wealth) and alcohol use (current drinking and HED amongst current drinkers).

FINDINGS

Surveys from 336 287 participants were included in the analysis. Among males, the highest prevalence of both current drinking and HED was found in lower-middle-income countries (L-MICs; current drinking 49·9% [95% CI 48·7-51·2] and HED 63·3% [61·0-65·7]). Among females, the prevalence of current drinking was highest in upper-middle-income countries (U-MIC; 29·5% [26·1-33·2]), and the prevalence of HED was highest in low-income countries (LICs; 36·8% [33·6-40·2]). Clear gradients in the prevalence of current drinking were observed across all country income groups, with a higher prevalence among participants with high socioeconomic status. However, in U-MICs, current drinkers with low socioeconomic status were more likely to engage in HED than participants with high socioeconomic status; the opposite was observed in LICs, and no association between socioeconomic status and HED was found in L-MICs.

INTERPRETATION

The findings call for urgent alcohol control policies and interventions in LICs and L-MICs to reduce harmful HED. Moreover, alcohol control policies need to be targeted at socially disadvantaged groups in U-MICs.

Reduced alcohol consumption during the COVID-19 pandemic: Analyses of 17 000 patients seeking primary health care in Colombia and Mexico

Background

During the COVID-19 pandemic, an increase of heavy alcohol use has been reported in several high-income countries. We examined changes in alcohol use during the pandemic among primary health care (PHC) patients in two middle income countries, Colombia and Mexico.

Methods

Data were collected during routine consultations in 34 PHC centres as part of a large-scale implementation study. Providers measured patients’ alcohol consumption with the three item ‘Alcohol Use Disorders Identification Test’ (AUDIT-C). Generalized linear mixed models were performed to examine changes in two dependent variables over time (pre-pandemic and during pandemic): 1) the AUDIT-C score and 2) the proportion of heavy drinking patients (8+ on AUDIT-C).

Results

Over a period of more than 600 days, data from N = 17 273 patients were collected. During the pandemic, the number of patients with their alcohol consumption measured decreased in Colombia and Mexico. Each month into the pandemic was associated with a 1.5% and 1.9% reduction in the mean AUDIT-C score in Colombia and Mexico, respectively. The proportion of heavy drinking patients declined during the pandemic in Colombia (pre-pandemic: 5.4%, 95% confidence interval (CI) = 4.8% to 6.0%; during the pandemic: 0.8%, 95% CI = 0.6% to 1.1%) but did not change in Mexico.

Conclusions

Average consumption levels declined and the prevalence of heavy drinking patterns did not increase. In addition to reduced opportunities for social drinking during the pandemic, changes in the population seeking PHC and restrictions in alcohol availability and affordability are likely drivers for lower levels of alcohol use by patients in this study.

The impact of alcohol taxation changes on unrecorded alcohol consumption: A review and recommendations

BACKGROUND

The diverse forms of unrecorded alcohol, defined as beverage alcohol not registered in official statistics in the country where it is consumed, comprise about one fourth of all alcohol consumed worldwide. Since unrecorded alcohol is usually cheaper than registered commercial alcohol, a standard argument against raising alcohol excise taxes has been that doing so could potentially result in an increase in unrecorded consumption. This contribution examines whether increases in taxation have in fact led to increases in consumption of unrecorded alcohol, and whether these increases in unrecorded alcohol should be considered to be a barrier to raising taxes. A second aim is to outline mitigation strategies to reduce unrecorded alcohol use.

METHODS

Narrative review of primary and secondary research, namely case studies and narrative and systematic reviews on unrecorded alcohol use worldwide.

RESULTS

Unrecorded alcohol consumption did not automatically increase with increases in taxation and subsequent price increases of registered commercial alcohol. Instead, the level of unrecorded consumption depended on: a) the availability and type of unrecorded alcohol; b) whether such consumption was non-stigmatized; c) the primary population groups which consumed unrecorded alcohol before the policy change; and d) the policy measures taken. Mitigation strategies are outlined.

CONCLUSIONS

Potential increases in the level of unrecorded alcohol consumption should be considered in the planning and implementation of substantial increases in alcohol taxation. However, unrecorded consumption should not be considered to be a principal barrier to implementing tax interventions, as evidence does not indicate an increase in consumption if mitigation measures are put in place by governments.

Cross-sectional study on the characteristics of unrecorded alcohol consumption in nine newly independent states between 2013 and 2017

OBJECTIVES

As unrecorded alcohol use contributes to a substantial burden of disease, this study characterises this phenomenon in newly independent states (NIS) of the former Soviet Union with regard to the sources of unrecorded alcohol, and the proportion of unrecorded of total alcohol consumption. We also investigate associated sociodemographic characteristics and drinking patterns.

DESIGN

Cross-sectional data on overall and unrecorded alcohol use in the past 7 days from WHO STEPwise Approach to NCD Risk Factor Surveillance (STEPS) surveys. Descriptive statistics were calculated at the country level, hierarchical logistic and linear regression models were used to investigate sociodemographic characteristics and drinking patterns associated with using unrecorded alcohol.

SETTING

Nine NIS (Armenia, Azerbaijan, Belarus, Georgia, Kyrgyzstan, Republic of Moldova, Tajikistan, Turkmenistan and Uzbekistan) in the years 2013-2017.

PARTICIPANTS

Nationally representative samples including a total of 36 259 participants.

RESULTS

A total of 6251 participants (19.7%; 95% CI 7.9% to 31.5%) reported alcohol consumption in the past 7 days, 2185 of which (35.1%; 95% CI 8.2% to 62.0%) reported unrecorded alcohol consumption with pronounced differences between countries. The population-weighted average proportion of unrecorded consumption in nine NIS was 8.7% (95% CI 5.9% to 12.4%). The most common type of unrecorded alcohol was home-made spirits, followed by home-made beer and wine. Older (45-69 vs 25-44 years) and unemployed (vs employed) participants had higher odds of using unrecorded alcohol. More nuanced sociodemographic differences were observed for specific types of unrecorded alcohol.

CONCLUSIONS

This contribution is the first to highlight both, prevalence and composition of unrecorded alcohol consumption in nine NIS. The observed proportions and sources of unrecorded alcohol are discussed in light of local challenges in policy implementation, especially in regard to the newly formed Eurasian Economic Union (EAEU), as some but not all NIS are in the EAEU.

Unrecorded alcohol consumption in Thailand: Prevalence, geographical variation, relationship with socioeconomic factors and related consequences

INTRODUCTION

Information on unrecorded alcohol consumption in Southeast Asia and Thailand is lacking. The primary objective of this study was to estimate the prevalence of unrecorded alcohol (including illegally produced alcohol and untaxed cross-border alcohol) consumption among past-year drinkers in Thailand. The secondary objectives were to examine the geographical variation of unrecorded alcohol consumption, effects of socioeconomic factors on unrecorded alcohol consumption and the association between unrecorded alcohol consumption and alcohol-related consequences.

METHODS

This study analysed data from the 2017 Smoking and Drinking Behavior Survey. The prevalence of unrecorded alcohol consumption was estimated. Associations of interest were tested using multivariate logistic regression.

RESULTS

Overall, 12.3% of past-year drinkers consumed any unrecorded alcohol. The prevalence was highest in the north (24.8%) and lowest in the central region (7.4%). In multivariate analysis, living in the north was associated with consumption of any unrecorded alcohol and illegally produced alcohol, whereas living in the south was associated with untaxed cross-border alcohol consumption. The lowest education and income group had the highest likelihood of consumption of any unrecorded alcohol and illegally produced alcohol, but the lowest likelihood of untaxed cross-border alcohol consumption. Consumption of unrecorded alcohol was associated with a higher chance of alcohol-related consequences.

DISCUSSION AND CONCLUSIONS

This study estimated the prevalence of unrecorded alcohol consumption among Thai drinkers and demonstrated the geographical variation in the prevalence and types of unrecorded alcohol consumed. We also found heterogenous associations between socioeconomic factors and each type of unrecorded alcohol.

Development of the policy of control over unrecorded alcohol in Russia in the period after 1991

Relevance. Unrecorded alcohol in Russia includes a variety of sources of cheap, often highly concentrated, ethanol, the use of which is associated with an increased risk of morbidity and death. Since 1991, various changes in the policy of control of unrecorded alcohol in Russia have been made, which became the subject of the analysis of this work.

Methods. The paper provides a narrative review and analysis of the regulation of unrecorded alcohol in Russia in the period from 1991 to 2021. The sources of information on legislative regulation were the ConsultantPlus and Garant electronic legal reference systems, published key scientific papers and reports of international organizations on the topic of alcohol regulation, and our own analysis of alcohol policy.

Results. During the study period, there was a large-scale restructuring of the regulation of the sphere of alcohol, including unrecorded alcohol, in Russia in the conditions of a new market economy. After the abolition of the Soviet alcohol monopoly and the regulatory pause of the first half of the 1990s, since 1995, the new legislative framework has been developed aimed at strengthening state control over the production and distribution of alcohol. In subsequent years, increased control over unrecorded alcohol by improving federal law No. 171-FZ, tougher sanctions for acts in the field of illegal production and distribution of alcohol through the improvement of the Code of Administrative Offenses and the Criminal Code of the Russian Federation, the introduction of minimum prices for alcoholic beverages, have been made. An electronic system for monitoring the volumes of produced and sold alcoholic beverages was introduced, the Federal Service for the Regulation of the Alcohol Market was established, and bans were introduced on the sale of alcohol-containing products with a low unit cost of ethanol.

Conclusions. Overall, the policy on the control of unrecorded alcohol in Russia in the period after 1991 from the standpoint of public health can be characterized as positive and in line with international standards. However, it is necessary to strengthen control over the implementation of the already existing alcohol control policy measures, as well as to develop and implement new measures aimed at controlling unrecorded medicinal/pharmaceutical alcohol, medicinal alcohol-containing products, illegal alcoholic beverages and non-beverage products used as alcohol surrogates.

Mortality in the Americas from 2013 to 2015 resulting from diseases, conditions and injuries which are 100% alcohol-attributable

AIMS

To describe mortality in the Americas from 2013 to 2015 inclusive resulting from diseases, conditions and injuries which are 100% attributable to alcohol consumption.

DESIGN AND SETTING

Mortality registry, population-based study. The data come from 30 of the 35 countries of the Americas for the triennium of 2013 to 2015.

PARTICIPANTS AND CASES

A total of 18 673 791 deaths coded by three-digit ICD-10 codes were analyzed.

MEASUREMENTS

Cause (underlying), and age-specific and age-adjusted mortality rates were calculated by sex and country.

FINDINGS

From 2013 to 2015 inclusive, among 30 of the 35 countries of the Americas, an average of 85 032 deaths per year were entirely attributable to alcohol. Men accounted for 83.1% of all 100% alcohol-attributable deaths, and death rates were higher for men than for women across all countries; however, the ratios of 100% alcohol-attributable deaths by sex varied by country. The majority of all 100% alcohol-attributable deaths occurred among those aged under 60 years (64.9%) and were due to liver disease (63.9%) followed by neuropsychiatric disorders (27.4%). Age-adjusted 100% alcohol-attributable mortality rates were highest in Nicaragua (23.2 per 100 000) and Guatemala (19.0 per 100 000), although the majority of all 100% alcohol-attributable deaths occurred in the United States 36.9%), Brazil (24.8%), and Mexico (18.4%).

CONCLUSIONS

From 2013 to 2015, more than 85 000 deaths in the Americas were 100% attributable to alcohol. Most of those occurred in people under 60 years and the highest mortality rates occurred in the United States, Brazil and Mexico.

Societal development and the alcohol-attributable burden of disease

AIM

This study aimed to examine if there is an interaction between alcohol use and human development in terms of their associations with alcohol-attributable health harms.

DESIGN

Statistical modelling of global country- and region-specific data from 2016.

SETTING

Global.

PARTICIPANTS/CASES

The units of the analyses were countries (n = 180) and regions (n = 4) based on their Human Development Index (HDI).

MEASUREMENTS

Alcohol-attributable harms [deaths, years of life lost (YLL), years lived with disability (YLD) and disability-adjusted life years (DALYs) lost] and risk relations were based on a recent study using World Health Organization (WHO) estimates for 2016. Human development was measured using the HDI, a summary score of life expectancy, education and gross national income from the United Nations Development Programme. Interactions between HDI and adult per-capita consumption (APC) affecting alcohol-attributable harms were assessed using likelihood ratio tests. Differences in alcohol-attributable harms per litre of APC between HDI groups were assessed using regression analyses and a reference group of low HDI.

FINDINGS

APC is associated with alcohol-attributable deaths, YLL, YLDs and DALYs lost, while HDI is associated with alcohol-attributable deaths, YLL and DALYs lost. Statistical analyses indicated there is an interaction between HDI and APC in their associations with alcohol-attributable deaths, YLL and DALYs lost per 100 000 people. The alcohol-attributable burden was highest in low HDI countries, with 11.65 [95% confidence interval (CI) = 10.75, 12.40] deaths and 495.61 (95% CI = 461.83, 569.23) DALYs lost per 100 000 people per litre of APC, and lowest in very high HDI countries, with 4.15 (95% CI = 2.46, 5.71) deaths and 200.31 (95% CI = 122.78, 265.10) DALYs lost per 100 000 people per litre of APC. However, no statistical differences between low and very high HDI groupings for these burdens were observed.

CONCLUSIONS

There appears to be an interaction between the Human Development Index and alcohol use in their associations with alcohol-attributable deaths, years of life lost and disability-adjusted life years lost but not with alcohol-attributable years lived with disability. Alcohol appears to have a stronger harmful impact per litre of alcohol consumed in lesser developed countries than in developed countries.

A systematic comparison of the global comparative risk assessments for alcohol

AIMS

To compare systematically the alcohol-attributable mortality and burden of disease estimates for 2016 from a recent study by Shield and colleagues and the Global Burden of Disease study 2017 (GBD).

METHOD

This study compared estimates of alcohol-attributable mortality and disability adjusted life years (DALYs) lost for 2016 with regards to absolute and relative differences, by region and by cause of disease or injury. Relative differences between the two studies are reported herein as percentage (%) differences. A difference of 10% or more was considered meaningful.

RESULTS

The studies estimated similar global levels of overall alcohol-attributable mortality for 2016 (Shield and colleagues estimated 5.1% more alcohol-attributable mortality than the GBD study) but not alcohol-attributable DALYs lost (18.3% difference). There were marked differences by region and cause of disease or injury. Compared with the results from Shield and colleagues, the GBD study estimated a lower alcohol-attributable burden in Eastern Europe by 252 770 alcohol-attributable deaths (45.2% difference) and 6.1 million alcohol-attributable DALYs lost (32.9% difference) and in Western sub-Saharan Africa by 124 200 alcohol-attributable deaths (55.7% difference) and 7.0 million alcohol-attributable DALYs lost (63.4% difference), and estimated a higher alcohol-attributable burden in East Asia by 227 100 alcohol-attributable deaths (48.0% difference) and 2.2 million DALYs lost (11.0% difference). With regard to the cause of disease or injury, Shield and colleagues attributed an overall detrimental effect to alcohol on ischaemic heart disease mortality, whereas the GBD study attributed a net beneficial effect. The GBD study, as compared with Shield and colleagues' study, estimated a lower alcohol-attributable mortality because of liver cirrhosis and injuries by 262 500 (44.6% difference) and 398 800 (46.2% difference), respectively.

CONCLUSIONS

Differences in estimates of the alcohol-attributable burden of disease in two recent studies indicate the need to improve the accuracy of underlying data and risk relations to obtain more consistent estimates and to formulate, advocate for, and implement alcohol policies more effectively.

The Contribution of Alcohol Beverage Types to Consumption, Heavy Drinking, and Alcohol-Related Harms: A Comparison across Five Countries

BACKGROUND

This study examined the relative contribution of alcoholic beverage types to overall alcohol consumption and associations with heavy alcohol use and alcohol-related harms among adults.

METHODS

Cross-sectional survey data were collected from adult samples in two cities involved in the Global Smart Drinking Goals (GSDG) initiative in each of five countries (Belgium, Brazil, China, South Africa, United States). Survey measures included past-30-day consumption of beer, wine, flavored alcoholic drinks, spirits, and homemade alcohol; past-30-day heavy drinking; 14 alcohol-related harms in the past 12 months; and demographic characteristics. Within in each country, we computed the proportion of total alcohol consumption for each beverage type. Regression analyses were conducted to estimate the relative associations between consumption of each alcoholic beverage type, heavy alcohol use, and alcohol-related harms, controlling for demographic characteristics.

RESULTS

Beer accounted for at least half of total alcohol consumption in GSDG cities in Belgium, Brazil, the U.S., and South Africa, and 35% in China. Regression analyses indicated that greater beer consumption was associated with heavy drinking episodes and with alcohol-related harms in the cities in Belgium, Brazil, South Africa, and the U.S. Significant increases in heavy drinking and alcohol-related harms were also consistently observed for spirits consumption.

CONCLUSIONS

Beer accounts for the greatest proportion of total alcohol consumption in most of the GSDG cities and was consistently associated with more heavy drinking episodes and alcohol-related harms. Reducing beer consumption through evidence-based interventions may therefore have the greatest impact on hazardous drinking and alcohol-related harms.

Impact of alcohol on mortality in Eastern Europe: Trends and policy responses

Within the global context, Eastern Europe has been repeatedly identified as the area with the highest levels of alcohol-related health harms. Although the Berlin Wall fell in 1989, and the Soviet Union collapsed soon afterwards, alcohol-related mortality in Eastern Europe remains far higher than in Western Europe. However, despite the high burden of alcohol harm and mortality in Eastern Europe, with the partial exception of Russia, relatively little is known about the country-specific impact of alcohol on health and mortality and the various policy responses to it. In response to this, an international symposium was held in Vilnius, Lithuania in June 2017 entitled Persisting burden of alcohol in Central and Eastern Europe: recent evidence and measurement issues. This special section of Drug and Alcohol Review is based on a selection of the papers presented at this symposium, providing for the first time a broad overview of the problem of alcohol-related mortality in a diverse range of Eastern European countries linked to a description and analysis of alcohol control initiatives that have been developed. While there is strong evidence of the influence of history, culture and education across European countries having a profound and persistent effect on differences in drinking patterns and preferences, there is, nevertheless, evidence that effective policy responses have been mounted in a range of countries.

Epidemiological Realities of Alcoholic Liver Disease: Global Burden, Research Trends, and Therapeutic Promise

Globally, alcohol consumption contributes to more than 3 million deaths each year. While much of its ramifications is preventable, a coherent public health discourse on how to limit alcohol-related harm has been overdue. By synthesizing information from national and global databases, we show in this analysis that alcohol consumption level and alcohol-attributable burden of diseases, particularly alcoholic liver disease (ALD), are intimately linked to national income distribution, cultural norms, religion, sex, age, and health status. Prevalence and burden of ALD are positively associated with economic standing in most countries, which necessitate active governmental control via cost-effective policies, such as the best buys proposed by the World Health Organization. To date, a number of critical questions remain unanswered over the molecular mechanisms underlying ALD pathophysiology; the insights gained thereof should provide new opportunities for the advancement of novel diagnostic and management strategies. In comparison with other prevailing liver diseases (e.g., viral hepatitis and nonalcoholic fatty liver disease), governmental support to ALD investigation has been sluggish in most Western countries and China, resulting in a dearth of breakthroughs on both the basic and clinical research fronts in the past decades. Emerging foci of clinical trials for ALD therapy include empirical use of probiotics, antioxidants, growth factors, monoclonal antibodies against key inflammatory mediators, and technology-enhanced behavioral interventions. In this article, we seek to provide a comprehensive analysis on the progress and challenges in tackling ALD as a global health problem, with particular emphasis on global disease burden, socioeconomic influences, research trends, government roles, and future therapies.

Russia's National Concept to Reduce Alcohol Abuse and Alcohol-Dependence in the Population 2010-2020: Which Policy Targets Have Been Achieved?

In the 2000s, Russia was globally one of the top 5 countries with the highest levels of alcohol per capita consumption and prevailing risky patterns of drinking, i.e., high intake per occasion, high proportion of people drinking to intoxication, and high frequency of situations where alcohol is consumed and tolerated. In 2009, in response to these challenges, the Russian government formed the Federal Service for Alcohol Market Regulation and published a national strategy concept to reduce alcohol abuse and alcohol-dependence at the population level for the period 2010-2020. The objectives of the present contribution are to analyze the evidence base of the core components of the concept and to provide a comprehensive evaluation framework of measures implemented (process evaluation) and the achievement of the formulated targets (effect evaluation). Most of the concept's measures were found to be evidence-based and aligned with eight out of 10 areas of the World Health Organization (WHO) policy portfolio. Out of the 14 tasks, 7 were rated as achieved, and 7 as partly achieved. Ten years after the concept's adoption, alcohol consumption seems to have declined by about a third and alcohol is conceptualized as a broad risk factor for the population's health in Russia.

Assessing alcohol consumption through wastewater-based epidemiology: Spain as a case study

BACKGROUND

In this study, an alternative and complementary method to those approaches currently used to estimate alcohol consumption by the population is described. This method, known as wastewater-based epidemiology (WBE), allows back-calculating the alcohol consumption rate in a given population from the concentrations of a selected biomarker measured in wastewater.

METHODS

Composite (24-h) wastewater samples were collected at the inlet of 17 wastewater treatment plants located in 13 Spanish cities for seven consecutive days in 2018. The sampled area covered 12.8% of the Spanish population. Wastewater samples were analyzed to determine the concentration of ethyl sulfate, the biomarker used to back-calculate alcohol consumption.

RESULTS

Alcohol consumption ranged from 4.5 to 46 mL/day/inhabitant. Differences in consumption were statistically significant among the investigated cities and between weekdays and weekends. WBE-derived estimates of alcohol consumption were comparable to those reported by its corresponding region in the Spanish National Health Survey in most cases. At the national level, comparable results were obtained between the WBE-derived annual consumption rate (5.7 ± 1.2 L ethanol per capita (aged 15+)) and that reported by the National Health Survey (4.7 L ethanol per capita (aged 15+)).

CONCLUSIONS

This is the largest WBE study carried out to date in Spain to estimate alcohol consumption rates. It confirms that this approach is useful for establishing spatial and temporal patterns of alcohol consumption, which could contribute to the development of health care management plans and policies. Contrary to established methods, it allows obtaining information in a fast and relatively economical way.

Alcohol policy has saved lives in the Russian Federation

Alcohol use has been determined to be one of the main risk factors of, and contributors to, premature mortality in Russia, but no formal analysis of the impact of alcohol control policies has been undertaken so far. The present contribution is a commentary on a policy impact study undertaken by the World Health Organization on the effects of alcohol control measures on mortality and life expectancy in the Russian Federation. As part of the case study, all alcohol control policies in Russia from 1990 to 2018 were examined, and periods with differing policy intensity were distinguished based on the known effectiveness of different measures. Trends in all-cause mortality during these periods, and the shifts in trends between periods, were analysed using interrupted-time series methodology. As predicted, the intensity of alcohol control policies strongly impacted all-cause mortality. The experience of the Russian Federation in reducing the burden of disease caused by alcohol is a strong argument that effective alcohol policies are essential for improving the prospects for long and healthy lives.

Meeting the Global NCD Target of at Least 10% Relative Reduction in the Harmful Use of Alcohol: Is the WHO European Region on Track?

BACKGROUND

The Global Action Plan for the Prevention and Control of Noncommunicable Diseases set the target of an "at least 10% relative reduction in the harmful use of alcohol, as appropriate, within the national context". This study investigated progress in the World Health Organization (WHO) European Region towards this target based on two indicators: (a) alcohol per capita consumption (APC) and (b) the age-standardized prevalence of heavy episodic drinking (HED).

METHODS

Alcohol exposure data for the years 2010-2017 were based on country-validated data and statistical models.

RESULTS

Between 2010 and 2017, the reduction target for APC has been met with a decline by -12.4% (95% confidence interval (CI) -17.2, -7.0%) in the region. This progress differed greatly across the region with no decline for the EU-28 grouping (-2.4%; 95% CI -12.0, 7.8%) but large declines for the Eastern WHO EUR grouping (-26.2%; 95% CI -42.2, -8.1%). Little to no progress was made concerning HED, with an overall change of -1.7% (-13.7% to 10.2%) in the WHO European Region.

CONCLUSIONS

The findings indicate a divergence in alcohol consumption reduction in Europe, with substantial progress in the Eastern part of the region and very modest or no progress in EU countries.
