Does beverage type and drinking context matter in an alcohol-related injury? Evidence from emergency department patients in Latin America

Population-Level Alcohol Consumption and Homicide Rates in Latin America: A Fixed Effects Panel Analysis, 1961-2019

Latin America and the Caribbean (LAC) possesses 8 per cent of the global population but approximately one-third of global homicides. The region also exhibits high per capita alcohol consumption, risky drinking patterns and a heterogeneous mix of beverage preferences. Despite this, LAC violence receives limited attention in the English-language literature and there are no studies of the population-level alcohol-homicide association in the region. We examined the effects on total, male and female homicide rates of total and beverage-specific alcohol consumption (22 nations, 1961-2019) and of risky drinking patterns (20 nations, 2005 and 2010). We collected homicide and alcohol data from the World Health Organization. Panel fixed effects models showed (1) per capita total and wine consumption were positively associated with total, male and female homicide rates, though effects were much stronger for males, (2) per capita beer consumption was positively associated with total and male homicide rates, (3) per capita spirits consumption was not associated with homicide rates, and (4) nations with riskier drinking patterns had higher total, male and female homicide rates than those with less risky drinking patterns.

Road traffic injury risk from alcohol and cannabis use among emergency department patients in Argentina

Objective

To report the risk from alcohol, cannabis, and their combined use for non-fatal road traffic injuries for drivers, passengers, and pedestrians.

Methods

Risk was estimated using the case-crossover method. Participants (N= 306) were injured patients from an emergency department in Mar del Plata, Argentina.

Results

Alcohol use (OR= 6.78, CI 95% 3.75-12.25) as well as combined alcohol and cannabis use (OR= 7.05, CI 95% 1.16-42.73) significantly increased the risk of a road traffic injuries. Alcohol use increased the risk in both, women (OR= 8.87, CI 95% 2.69-29.21) and men (OR= 6.16, CI 95% 3.10-12.23); in those >30 years old (OR= 6.01, CI 95% 2.09-17.24) and those <30 years old (OR= 7.15, CI 95% 3.49-14.65). This last group also had an increased risk after combined alcohol and cannabis use (OR= 7.05, CI 95% 1.16-42.75). Both drivers (OR= 6.40, CI 95% 3.23-12.69) and passengers (OR= 13.83, CI 95% 2.87-66.42) had an increased risk after alcohol consumption.

Conclusions

To our knowledge, these are the first estimates of the risk of having a road traffic injury after alcohol and cannabis consumption in one of the countries of the Southern Cone (Argentina, Chile, and Uruguay). These results highlight the urgent need to implement and enforce comprehensive alcohol control measures. Furthermore, given the global trend towards legalizing cannabis for recreational use, our results could also inform policymakers to enact or amend impaired driving laws.

Association between self-reported binge drinking and absenteeism in the Baltic countries

Objective

Substantial loss of productivity due to absenteeism is associated with alcohol use. This study examined the associations between absenteeism in the workplace and in schools and binge drinking across various beverage types in the Baltic countries.

Methods

We utilised a dataset of 3,778 individuals compiled from 2015 to 2016 and performed multiple negative binomial regression analysis with multiple imputations to deal with missing data. Self-reported measures were used for both absenteeism and binge drinking.

Results

We found evidence to support the claim that absenteeism, in terms of self-reported absence days, is positively associated with self-reported binge drinking, specifically with beer bingeing. On average, beer bingers reported 49% (p < .05) more absences than people who drink alcohol but do not binge on beer. For wine and spirits variables, the estimates indicated positive but statistically insignificant associations. No group differences were identified across gender and education.

Conclusions

A considerable proportion of days absent from work and from school can be associated with beer bingeing. Therefore, it should be acknowledged that beverage-specific alcohol policies that are more lenient toward beer than other types of alcohol can inadvertently increase absenteeism and decrease workplace productivity.

The association between the time of alcohol drinking and injury risk in Thailand: a cross-sectional emergency department study

BACKGROUND

Although the relationship between acute alcohol consumption and injuries is well recognized, studies exploring how the time of day the drinking commences affects alcohol-related injuries have been scarce. This contribution examines the associations between the time at which the drinking began and the duration of the drinking, the volume of alcohol consumed, the injury type, and the blood alcohol concentration (BAC) level.

METHOD

This study employed a cross-sectional survey, which was conducted in two hospital emergency departments (ED) in Chiangmai Province, Thailand. The sample was composed of 519 injured patients aged 18 years and older. Outcome measures included the BAC and type of injury. Exposures included the quantity of alcohol consumed, the time the drinking commenced, and the pattern of drinking involved.

RESULTS

The injured patients who drank alcohol within six hours prior to sustaining their injury were more likely to get injured and present themselves at the ED at night (20:00-04:00) compared to those who sustained an injury but did not drink in the hours prior. However, this relationship was only true for unintentional injuries, not intentional ones. The majority of participants consumed their first drink between 16:00 and 20:00. On average, among the 104 patients who drank prior to sustaining an injury, the total amount of alcohol consumed was 6.9 drinks, the duration of drinking was 2.6 h, the rate of drinking was 6.0 drinks/hour, and the BAC was 0.119 gm%. Every drink increased the BAC by 0.012 gm% and each year of increasing age increased the BAC by 0.003 gm%. People who were older, less educated, and drank more frequently tended to have their first drink earlier than other drinkers. An earlier start to their drinking resulted in a faster pace of drinking and a higher BAC.

CONCLUSIONS

BAC increased with the total amount of alcohol consumed and the age of the drinker. Different groups of people had their first drink at different times of the day, resulting in differences in the rate of drinking, the BAC, the time of injury, and the time they presented to the ED after injury.

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.

Drinking contexts and their association with acute alcohol-related harm: A systematic review of event-level studies on adults' drinking occasions

ISSUES

Event-level alcohol research can inform prevention efforts by determining whether drinking contexts-such as people or places-are associated with harmful outcomes. This review synthesises evidence on associations between characteristics of adults' drinking occasions and acute alcohol-related harm.

APPROACH

We systematically searched Ovid MEDLINE, Ovid PsycInfo and the Web of Science Social Sciences Citation Index. Eligible papers used quantitative designs and event-level data collection methods. They linked one or more drinking contexts to acute alcohol-related harm. Following extraction of study characteristics, methods and findings, we assessed study quality and narratively synthesised the findings.

PROSPERO ID

CRD42018119701.

KEY FINDINGS

Searches identified 95 eligible papers, 65 (68%) of which study young adults and 62 (65%) of which are set in the United States, which limits generalisability to other populations. These papers studied a range of harms from assault to drink driving. Study quality is good overall although measures often lack validation. We found substantial evidence for direct effects of drinking context on harms. All of the contextual characteristics types studied (e.g. people, place, timing, psychological states, drink type) were consistently associated with harms. Certain contexts were frequently studied and associated with harms, in particular, weekend drinking, drinking in licensed premises and concurrent illicit drug use.

IMPLICATIONS

The findings of our review indicate target drinking contexts for prevention efforts that are consistently associated with increased acute alcohol-related harm.

CONCLUSION

A large range of contextual characteristics of drinking occasions are directly associated with acute alcohol-related harm, over and above levels of consumption.

Different demographic and drinking profiles of motorcyclists and car drivers with the first-time offense of driving/riding under the influence of alcohol

BACKGROUND

Driving/riding under the influence (DUI) of alcohol is a major public concern worldwide. Only a few studies have distinguished DUI-related variables between motorcyclists and car drivers. This study examined the differences in demographic characteristics and drinking behaviors among first-time DUI offenders operating different transportation vehicles, and risk factors for frequent DUI (fDUI) among them.

METHODS

We conducted an anonymous survey for 561 first-time DUI offenders who attended a mandatory educational program. Participants self-administered questionnaires concerning alcohol drinking behaviors and DUI. We defined fDUI as at least two DUI behaviors per month based on self-reported information. Demographic and drinking characteristics were compared between DUI offenders, car drivers and motorcyclists. Logistic regression analysis was used to examine risk factors for fDUI.

RESULTS

Two-thirds of first-time DUI offenders were motorcyclists. Compared with car drivers, motorcyclists were younger and less educated, with a higher percentage of them being women and unmarried. Car drivers reported a higher rate of fDUI than motorcyclists (16.5% vs. 9.7%). Regression analysis revealed that binge drinkers had a higher fDUI risk in both groups. Regarding the drinking place prior to DUI behavior, workplace was significantly associated with fDUI in car drivers.

CONCLUSIONS

Distinct strategies may be required for motorcyclists and car drivers for DUI recidivism prevention, and drinking place interventions should also be considered.

Risk of Alcohol-Related Injury: Does Societal Drinking Context Make a Difference?

OBJECTIVE

The aim of this study is to examine whether country-level frequency of drinking in a public context and in a private context is associated with rates of alcohol-related injury in emergency department studies from those same countries.

METHOD

Emergency department data on 5,104 injured patients in 10 countries from the International Collaborative Alcohol and Injury Study (ICAIS) and aggregate level drinking context data from the Gender, Alcohol and Culture: An International Study (GENACIS) are analyzed. The association of societal drinking context (public and private) with variation in the rate of self-reported drinking before injury is examined using multilevel modeling.

RESULTS

Controlling for demographic characteristics, individual-level volume and drinking pattern, study-level volume, and country-level drinking pattern and alcohol control policy, societal public drinking context was significantly predictive of an alcohol-related injury (odds ratio [OR] = 1.08, CI [1.02, 1.13]), whereas societal private drinking context was not. Public drinking context was predictive of violence-related injury (OR = 1.09, CI [1.01, 1.17]), whereas private drinking context was predictive of injuries from falls (OR = 1.01, CI [1.01, 1.02]). Neither societal drinking context was significantly predictive of traffic-related injuries whereas both public (OR = 1.06, CI [1.01, 1.12]) and private (OR = 1.01, CI [1.01, 1.03]) contexts were predictive of injuries from other causes.

CONCLUSIONS

These data suggest that societal drinking context does make a difference in the likelihood of an alcohol-related injury, which is important for a better understanding of the role of drinking context in a country in the occurrence of an alcohol-related injury and may inform future recommendations for reducing this harmful consequence.

Problem drinking among Flemish students: beverage type, early drinking onset and negative personal & social consequences

Background

Although alcohol is socially accepted in most Western societies, studies are clear about its associated negative consequences, especially among university and college students. Studies on the relationship between alcohol-related consequences and both beverage type and drinking onset, however, are scarce, especially in a European context. The aim of this research was, therefore, twofold: (1) What is the relationship between beverage type and the negative consequences experienced by students? and (2) Are these consequences determined by early drinking onset? We will examine these questions within the context of a wide range of alcohol-related consequences.

Methods

The analyses are based on data collected by the inter-university project ‘Head in the clouds?’, measuring alcohol use among students in Flanders (Belgium). In total, a large dataset consisting of information from 19,253 anonymously participating students was available. Negative consequences were measured using a shortened version of the Core Alcohol and Drug Survey (CADS_D). Data were analysed using negative binomial regression.

Results

Results vary depending on the type of alcohol-related consequences: Personal negative consequences occur frequently among daily beer drinkers. However, a high rate of social negative consequences was recorded for both daily beer drinkers and daily spirits drinkers. Finally, early drinking onset was significantly associated with both personal and social negative consequences, and this association was especially strong between beer and spirits drinking onset and social negative consequences.

Conclusions

Numerous negative consequences, both personal and social, are related to frequent beer and spirits drinking. Our findings indicate a close association between drinking beer and personal negative consequences as well as between drinking beer and/or spirits and social negative consequences. Similarly, early drinking onset has a major influence on the rates of both personal and social negative consequences. The earlier students started drinking, the more negative consequences they experienced during college or university. Several (policy) interventions are discussed. This study is the first to incorporate detailed information on both beverage type and drinking onset, and its associated negative consequences, as measured by the CADS_D, in a large student population.

Risk of Past Year Injury Related to Hours of Exposure to an Elevated Blood Alcohol Concentration and Average Monthly Alcohol Volume: Data from 4 National Alcohol Surveys (2000 to 2015)

BACKGROUND

While a strong association exists between alcohol and injury in emergency department (ED) studies, these studies are not representative of the general population.

METHODS

The association of injury with the number of hours of exposure to a blood alcohol concentration (BAC) ≥ 0.05 and average monthly volume in drinks, both based on self-report of quantity and frequency of drinking in the last year, in a merged sample of respondents (n = 29,571) from 4 U.S. National Alcohol Surveys (2000 to 2015) are analyzed. Risk curves based on categorical step function and fractional polynomial modeling were analyzed separately by gender, and by age and race/ethnicity for males.

RESULTS

Risk of injury increased at 1 hour of a BAC exposure of ≥ 0.05 and at an average monthly volume of 1 drink. Risk of injury for spirits increased to an average daily volume of 1 drink, but no association was found for injury risk and average volume for either wine or beer. Risk of injury increased with both exposure hours and monthly volume among males, but little association was found for either consumption measure with risk of injury for females. Among males, increased risk of injury was greater for whites than for blacks or Hispanics for BAC exposure; Hispanics showed a continued elevated risk up to 8 hours of exposure. After peaking at a monthly volume of 1 drink, injury risk decreased substantially for blacks, but was more gradual for whites, while risk increased very slightly for Hispanics to about 4 drinks per day. Males aged 18 to 29 showed the largest increase in risk associated with the number of hours of exposure to a BAC of ≥0.05, with risk doubling at 1 hour of exposure, but subsequently falling.

CONCLUSIONS

While findings here are weaker than those from ED studies and likely due to the context of drinking, risk of injury appears to increase at relatively low levels of consumption, suggesting the importance of preventive efforts to reduce injury not only for heavier drinkers but also for more moderate drinkers.

[Taxation of traditional rums in French overseas territories and public health: The example of Reunion Island]

BACKGROUND

France has a complex system for the taxation of alcoholic beverages. In the French overseas territories (FOT), the system includes little-known specificities whose purpose is to preserve the sugar-cane-rum sector, a pillar for the weak economies in these territories. Taxes are reduced for traditional rums produced and sold locally. This favors the marketing of alcoholic spirits at low prices. In metropolitan France, on the contrary, spirits are heavily taxed drinks and their share in consumption is minor. Reunion Island (RI) is a FOT confronted with significant socioeconomic precariousness and with one of the highest national morbidity and mortality rates associated with alcohol abuse. Spirits account for half of the total consumption of pure alcohol, with a strong predominance for local traditional rums. These products are preferentially consumed by vulnerable subjects, often affected by an alcohol-use disorder.

METHODS

This study consists of three parts. First, a comparative analysis of alcoholic beverage prices between RI and mainland France. Second, an analysis of the bibliography on the consequences of preferential consumption of spirits. Third, a literature review on the impact of taxation on alcohol-related morbidity and mortality.

RESULTS

In France, the cheapest gram of pure alcohol is found in the FOT. The preferential consumption of spirits is associated with more frequent and more rapid complications. It is correlated with the level of alcoholic psychoses. Taxation is effective in reducing damage caused by the abuse of alcoholic beverages. The World Health Organization recommends the application of a minimum price for alcohol and tax increases.

CONCLUSION

The reduced taxation of the traditional rums of the FOT does not take into account public health data. Its purpose is economic. In RI, it contributes to a high level of consumption of spirits and encourages excess mortality through alcohol abuse. It constitutes an inequality of health for these populations. Changes in this tax system is desirable in order to reduce the harm caused by alcohol. It should be closer to the tax system in force in metropolitan France. Alcohol lobbies and lack of political courage have so far inhibited this change to the detriment of the health of the populations.

Alcohol use among fatally injured victims in São Paulo, Brazil: bridging the gap between research and health services in developing countries

BACKGROUND AND AIMS

Most studies reporting alcohol use among fatally injured victims are subject to bias, particularly those related to sample selection and to absence of injury context data. We developed a research method to estimate the prevalence of alcohol consumption and test correlates of alcohol use prior to fatal injuries.

DESIGN, SETTING AND PARTICIPANTS

Cross-sectional study based on a probability sample of fatally injured adult victims (n = 365) autopsied in São Paulo, Brazil. Victims were sampled within systematically selected 8-hour sampling blocks, generating a representative sample of fatal injuries occurring during all hours of the day for each day of the week between June 2014 and December 2015.

MEASUREMENTS

The presence of alcohol and blood alcohol concentration (BAC) were the primary outcomes evaluated according to victims' socio-demographic, injury context data (type, day, time and injury place) and criminal history characteristics.

FINDINGS

Alcohol was detected in 30.1% [95% confidence interval (CI) = 25.6-35.1)] of the victims, with a mean blood alcohol level (BAC) level of 0.11% w/v (95% CI = 0.09-0.13) among alcohol-positive cases. Black and mixed race victims presented a higher mean BAC than white victims (P = 0.03). Fewer than one in every six suicides tested positive for alcohol, while almost half of traffic-related casualties were alcohol-positive. Having suffered traffic-related injuries, particularly those involving vehicle crashes, and injuries occurring during weekends and at night were associated significantly with alcohol use before injury (P < 0.05).

CONCLUSIONS

Nearly one-third of fatal injuries in São Paulo between June 2014 and December 2015 were alcohol-related, with traffic accidents showing a greater association with alcohol use than other injuries. The sampling methodology tested here, including the possibility of adding injury context data to improve population-based estimates of alcohol use before fatal injury, appears to be a reliable and lower-cost strategy for avoiding biases common in death investigations.

Deconstructing the Alcohol Harm Paradox: A Population Based Survey of Adults in England

Background

The Alcohol Harm Paradox refers to observations that lower socioeconomic status (SES) groups consume less alcohol but experience more alcohol-related problems. However, SES is a complex concept and its observed relationship to social problems often depends on how it is measured and the demographic groups studied. Thus this study assessed socioeconomic patterning of alcohol consumption and related harm using multiple measures of SES and examined moderation of this patterning by gender and age.

Method

Data were used from the Alcohol Toolkit Study between March and September 2015 on 31,878 adults (16+) living in England. Participants completed the AUDIT which includes alcohol consumption, harm and dependence modules. SES was measured via qualifications, employment, home and car ownership, income and social-grade, plus a composite of these measures. The composite score was coded such that higher scores reflected greater social-disadvantage.

Results

We observed the Alcohol Harm Paradox for the composite SES measure, with a linear negative relationship between SES and AUDIT-Consumption scores (β = -0.036, p<0.001) and a positive relationship between lower SES and AUDIT-Harm (β = 0.022, p<0.001) and AUDIT-Dependence (β = 0.024, p<0.001) scores. Individual measures of SES displayed different, and non-linear, relationships with AUDIT modules. For example, social-grade and income had a u-shaped relationship with AUDIT-Consumption scores while education had an inverse u-shaped relationship. Almost all measures displayed an exponential relationship with AUDIT-Dependence and AUDIT-Harm scores. We identified moderating effects from age and gender, with AUDIT-Dependence scores increasing more steeply with lower SES in men and both AUDIT-Harm and AUDIT-Dependence scores increasing more steeply with lower SES in younger age groups.

Conclusion

Different SES measures appear to influence whether the Alcohol Harm Paradox is observed as a linear trend across SES groups or a phenomenon associated particularly with the most disadvantaged. The paradox also appears more concentrated in men and younger age groups.
