Alcohol consumption in the G7 countries (1960-2021). Permanent versus transitory shocks

This paper analyses the degree of persistence in the level of consumption of alcohol in the Group of Seven (G7) countries by using fractional integration. The series under examination are annual sales of pure alcohol in litres per person aged 15 years and older, annually from 1960 to 2021, and we look at the influence that external shocks might have had on the series in these countries. The results indicate that only France displays a significant negative trend and thus a continuous decrease in the level of alcohol consumption. For the rest of the countries, the time trend is insignificant. Dealing with persistence, Japan is the only country that shows clear evidence of reversion to the mean. Policy recommendations are reported at the end of the manuscript.

[Sometimes, I Also Drink Water… - Alcohol Consumption of People With Mild Cognitive Impairment]

AIM

Risky alcohol consumption increases the risk of dementia for people with mild cognitive impairment (MCI). The aim of this study is to assess alcohol consumption in people with MCI.

METHODS

Socio-demographics, 12-month prevalence, 30-d prevalence, prevalence of risky consumption (>10 g/20 g/d pure alcohol for women/men) and binge drinking (≥50 g pure alcohol on one occasion) were recorded in 270 people (≥60 years) with MCI from the German RCT "Brainfit-Nutrition" in 2022.

RESULTS

Approximately half of the people with MCI (50.8%) drink at least once a week. About one fifth (17.0%) of participants met the criterion for binge drinking; every third woman (34.8%) and every fifth man (18.6%) crossed the line to risky consumption in the last 30 d.

DISCUSSION

Generally, people with MCI show similar consumption prevalence as the 65+German general population. However, the prevalence of risky consumption in women with MCI is significantly higher.

Dose-response relationship between alcohol consumption and workplace absenteeism in Australia

INTRODUCTION

Workplace absenteeism is a burden in Australia. The estimated productivity losses due to alcohol were around $4.0 billion in 2017, with absenteeism driving 90% of these costs. We aim to determine the dose-response relationship between average daily alcohol consumption and heavy episodic drinking (HED) frequency and workplace absenteeism amongst Australian workers.

METHODS

We used the 2019 National Drug Strategy Household Survey of Australian employed workers aged ≥20 years to 69 years old. Respondents' average daily alcohol consumption was categorised into four: abstainers, light to moderate (1-20 g of alcohol/day), risky (>20-40 g of alcohol/day) and high-risk (>40 g of alcohol/day). HED was classified into four frequency measures (never, less than monthly, monthly, weekly). The outcome variables came from dichotomised measures of: (i) absence due to alcohol consumption; and (ii) broader sickness absence-absence due to illness or injury in the previous 3 months.

RESULTS

Risky (adjusted odds ratio 4.74 [95% CI 2.93-7.64]) and high-risk drinking (adjusted odds ratio 6.61 [95% CI 4.10-10.68]) were linked to increased odds of alcohol-related absence. Higher HED frequency was significantly associated with alcohol-related and broader sickness absenteeism. No significant associations exist between regular alcohol consumption and broader sickness absence in fully adjusted models.

DISCUSSION AND CONCLUSIONS

Findings suggest that only HED is linked to broader sickness absence. However, there is a strong dose-response association between alcohol consumption and alcohol-related absences for both consumption measures amongst Australian workers. Population-level policies that reduce alcohol consumption to moderate level and less frequent HED might address workplace absenteeism.

A 13-item Health of the Nation Outcome Scale (HoNOS-13): validation by item response theory (IRT) in patients with substance use disorder

BACKGROUND

The Health of the Nation Outcome Scale (HoNOS) is a widely used 12-item tool to assess mental health and social functioning. The French version has an added 13th item measuring adherence to psychotropic medication. The aim of the current study is to uncover the unknown pattern of the new item 13 and to compare the unidimensional and multidimensional fit of the new HoNOS-13 using Item Response Theory (IRT). This research question was studied among inpatients with substance use disorder (SUD).

METHODS

Six hundred and nine valid questionnaires of HoNOS-13 were analyzed using unidimensional (one-factor) and multidimensional (two-factor) IRT modeling.

RESULTS

The multidimensional model suggesting a first factor capturing psychiatric/impairment-related issues and a second factor reflecting social-related issues yielded better goodness-of-fit values compared to the unidimensional solution. This resulted in an improvement of all slope parameters which in turn translates to better discriminative power. Significant improvement in item location parameters were observed as well. The new item 13 had a good discriminative power (1.17) and covered a wide range of the latent trait (- 0.14 to 2.64).

CONCLUSIONS

We were able to validate the 13-item questionnaire including medication compliance and suggest that the HoNOS-13 can be recommended as a clinical evaluation tool to assess the problems and treatment needs for inpatients with SUD. Interestingly, the majority of item response categories are endorsed by respondents who are below and above the average levels of HoNOS. This indicates that the scale is able to discriminate between participants both at the low and at the high ends of the latent trait continuum. More importantly, the new item 13 has a good discriminative power and covers a broad range of the latent trait below and above the mean. It therefore has the desired profile of a good item and is a useful measure for the assessment of mental health and social functioning. Trial registration ClinicalTrials.gov, Identifier: NCT03551301.

Age-period-cohort analysis of trends in tobacco smoking, cannabis use, and their co-use in the Australian population

BACKGROUND AND AIM

The prevalence of tobacco smoking has declined in most high-income countries, while cannabis use has been rising. Moreover, cannabis use has been found to have increased among cigarette smokers in recent years in jurisdictions where it has been either decriminalized or legalized. This study measured trends in cannabis, tobacco and the co-use of cannabis and tobacco in Australia.

DESIGN

Age-period-cohort analysis.

SETTING AND PARTICIPANTS

Participants were n = 143 344 individuals aged 18-80 years who participated in Australia's National Drug Strategy Household Surveys (NDSHS) between 2001 and 2019.

MEASUREMENTS

Regular (weekly/more frequently): (1) tobacco smoking only, (2) cannabis use only and (3) the co-use of cannabis and tobacco.

FINDINGS

Prevalence of only smoking tobacco decreased in all age groups (P < 0.001) and birth cohorts between 2001 and 2019, but the co-use of cannabis and tobacco did not. Younger cohorts were much less likely to co-use tobacco and cannabis (P = 0.02). Period trends showed that both cannabis use only and the co-use of cannabis and tobacco have increased since 2013.

CONCLUSION

There has been a consistent decrease in exclusive tobacco smoking across age, period and birth cohorts between 2001 and 2019 in Australia, although there is a recent increasing period trend in cannabis use with or without tobacco. The non-decreasing trend of co-use may reflect the strong tobacco control policies introduced over the period and changing attitudes towards cannabis use in Australia.

Did the under-reporting of meth/amphetamine use increase in a general population survey in Australia as negative media coverage increased?

AIM

To test (1) if there was a change in self-reported lifetime prevalence of meth/amphetamine use by birth cohort and (2) if the extent of under-reporting of meth/amphetamine use was associated with the proportion of the population who nominated meth/amphetamine as a drug problem.

DESIGN

Observational study using seven waves of repeated cross-sectional nationally representative household surveys between 2001 and 2019.

SETTING

Australia.

PARTICIPANTS

Participants were from three birth cohorts: 1951-60 (age 68-77 at the 2019 survey; n = 29 458; 55% female), 1961-1970 (age 58-67; n = 29 859; 57% female) and 1971-1980 (age 48-57; n = 28 758; 59% female). Data were weighted to align the sample to the Australian population.

MEASUREMENTS

Past year meth/amphetamine use; under-reporting of lifetime meth/amphetamine use in each birth cohort, year and survey stratum (operationalised as the difference between self-reported lifetime prevalence in 2001 and that of each subsequent year); proportion of the population who nominated meth/amphetamine as a drug problem in each birth cohort, year and survey stratum. Under-reporting was regressed on the proportion of people holding negative attitude towards meth/amphetamine. Survey year and birth cohort were adjusted for.

FINDINGS

Between 2001 and 2019, the lifetime prevalence of meth/amphetamine decreased from 6.1% (95% CI = 5.3-6.9) to 1.7% (95% CI = 1.2-2.2) in the 1951-1960 birth cohort (p < 0.001), from 13.0% (95% CI = 12.0-14.1) to 4.4% (95% CI = 3.7-5.2) in the 1961-1970 birth cohort (p < 0.001) and from 21.4% (95% CI = 19.9-22.9) to 11.2% (95% CI = 10.0-12.4) in the 1971-1980 birth cohort (p < 0.001). The proportion who nominated meth/amphetamine as a 'drug problem' increased significantly in all three cohorts (all p < 0.001) and the degree of under-reporting of meth/amphetamine use was significantly associated with proportion of people who nominated meth/amphetamine as the 'drug problem' (b = 0.09, SE = 0.01, p < 0.001).

CONCLUSION

In Australia, the actual prevalence of lifetime meth/amphetamine use may be two- to fourfold higher than that estimated in the most recent national household surveys (2019). The level of under-reporting is strongly associated with increasing negative attitudes towards methylamphetamine and d-amphetamine use over the same period.

Alcohol consumption, heavy episodic drinking and the perpetration of antisocial behaviours in Australia

AIMS

This study aims to understand the dose-response relationship of the volume and patterns of alcohol consumption with alcohol-related antisocial behaviours (ASB) in the general population and assess whether these relationships are consistent across various sociodemographic subgroups.

METHODS

We used data from 30,275 respondents aged (14-69) from two waves (2013 and 2016) of the National Drug Strategy Household Survey (NDSHS). Average daily alcohol consumption and heavy episodic drinking (HED) frequencies were treated as the main independent variables and self-reported ASB perpetration as the dependent variable. Bivariable and multivariable logistic regression models predicting ASB with interaction terms between alcohol consumption and various sociodemographic variables were estimated.

FINDINGS

Compared with low-risk drinking (0.01-20 g of alcohol/day), respondents drinking at risky (20.01-40 g of alcohol/day) and high risk (>40 g of alcohol per day) levels had an increased prevalence of ASB perpetration with adjusted odds ratios of 3.63 (95% CI 2.98-4.42) and 8.07 (6.72-9.71). Increasing frequency of HED was also linked to increased self-report of ASB perpetration in bivariable and multivariable models. In our interaction models, we found higher probabilities of ASB perpetration among younger and unmarried respondents for a given level of drinking.

DISCUSSION AND CONCLUSIONS

Both average daily alcohol consumption and frequency of HED predict the probability of perpetrating alcohol-related ASB. Unsurprisingly, the risk of alcohol-specific ASB increased more quickly with consumption levels for younger and single respondents, suggesting interventions to reduce consumption among younger and unmarried persons will significantly impact ASB.

Is smoking reduction and cessation associated with increased e-cigarette use? Findings from a nationally representative sample of adult smokers in Australia

AIMS

E-cigarettes may benefit public health if they are effective for smoking cessation. Evidence suggests that the frequency of e-cigarette use is likely an important predicator of smoking cessation success, so we examined the associations between frequency of e-cigarette use and smoking reduction and cessation in an Australian population sample of past year adult smokers.

METHODS

Data from the 2019 National Drug Strategy Household Survey were used (N = 22,015). The sample was restricted to 3868 adults who had smoked within the past year. The outcome was self-reported smoking status and smoking reduction, adjusted for key potential confounders.

RESULTS

Compared with no current e-cigarette use, daily e-cigarette users reported an increased likelihood for smoking reduction among current daily smokers (RRR = 2.83; 95% CI = 1.53, 5.22) and were more likely to report quitting smoking among past year smokers (RRR = 2.16; 95% CI = 1.30, 3.58). Smoking reduction and cessation for occasional e-cigarette use were not significantly different from no e-cigarette use.

CONCLUSIONS

Daily, but not occasional, e-cigarette users were more likely to quit or reduce smoking cigarettes than Australian smokers who did not use e-cigarettes.

An age-period-cohort analysis of trends in psychedelic and ecstasy use in the Australian population

AIM

To test the age, cohort, and period effect on past-year use trends in psychedelic drugs and ecstasy.

METHOD

Data were from a repeated cross-sectional nationally representative household survey in Australia conducted every three years between 2001 and 2019. An age-period-cohort model was used to test the effect of age, birth cohort, and period on past year psychedelic and ecstasy use. Participants were between 18 and 80 years old at the time of the survey. The total sample size was 149,296 (Mean age = 45.8; 56% female). Past-year use of psychedelics and ecstasy were the key outcome variables. There were six birth cohorts that were derived in each survey: 1936-50, 1951-60, 1961-70, 1971-80, 1981-90, and 1991-2001. There were seven periods that coincided with survey years: 2001, 2004, 2007, 2010, 2013, 2016 and 2019. Age was treated as continuous.

RESULTS

Past-year use of both psychedelics and ecstasy decreased with age, b = -0.87, 95% CI [-1.14, -0.61] and b = -0.84, 95% CI [-1.08, -0.60]. For ecstasy, while there was significant variation across periods (p < .001), there was no obvious trend. There was a significant birth cohort effect (p < .001), with prevalence increasing from the 1936-50 cohort, peaking in the 1971-80 cohort and then decreasing in the 1991-2001 cohort. For psychedelics, there was significant variation across periods (p < .001) with an upward trend. There was a significant birth cohort effect (p < .001), with prevalence increasing from the 1936-50 cohort to similarly high prevalence for the three most recent cohorts (1971-80, 1981-90, 1991-2001).

CONCLUSION

There were strong cohort and period effects in trends in the use of psychedelic and ecstasy.

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.

Violent Behaviours among Adolescents and Young Adults: Association with Psychoactive Substance Use and Parenting Styles

This study extends existing research on the relationship between psychoactive substance use among young people and violent behaviour, by evaluating the possible effect of the modification of parenting in a nationally representative sample of 14,685 Italian students drawn from the 2019 wave of the ESPAD Italia survey (51% male; mean age about 17 years). Parental dimensions considered in the study were rule-setting, monitoring, and emotional support, as well as the possible absence of a parent. Relative risk ratios and binary logistic regressions were used to estimate the associations separately for adolescents (15–17) and young adults (18–19). Overall, parental rule-setting, perceived parental monitoring, and emotional support were protective factors for substance use, and the strength of this relationship increased with the frequency of use. Among adolescents, the absence of a parent represented a risk factor. In both age groups, the odds of engaging in violent behaviour was increased among those reporting alcohol intoxication and substance use and the greater the frequency of use, the greater the increase in the odds. As parental monitoring and emotional support decreased, the odds of engaging in violent behaviour increased (except in the case of lower parental support among young adults), while the opposite applies to parental rule-setting. The odds of engaging in violent behaviour were increased among those reporting the absence of a parent only in the adolescent age group. Parental rule-setting was found to have an effect only among adolescents, increasing the odds of violent behaviour among frequent drinkers. Our results might be helpful to signal adolescents who would be more prone to adopt violent behaviour in order to target prevention policies.

Age-related trends in cannabis use in Australia. Findings from a series of large nationally representative surveys

AIM

We examine age-related trends in past-year cannabis use in a series of nationally representative surveys in Australia.

METHODS

We analysed data from the largest nationally representative survey in Australia collected between 2001 and 2019 (National Drug Strategy Household Survey [NDSHS]; N = 157,151). Prevalence of past-year daily/occasional (non-daily)/non-use of cannabis use were estimated using weighted multinomial logistic regression and predicted marginal probabilities. Difference-in-difference analysis was used to examine if trends of cannabis use across age groups were different.

RESULTS

The youngest age group (14-17 s) witnessed the largest increase in past-year abstinence rate from 79% to 92% from 2001 to 2019 (p < .003); the increase in abstinent rate among the 18-24 and 25-39 were relatively moderate (from 68 to 76% and from 81% to 84% respectively; p < .003). The abstinent rate among the 40-54 s and 55-74 s decreased significantly from 93% to 90% and from 99% to 95% respectively (p < .003). There were similar diverging trends in occasional and daily cannabis use, with decreases in both patterns of use observed among the younger age group (14-17 s and 18-25 s) but increases among the older age group (40-54 s and 55-74 s).

CONCLUSION

There is a diverging trend in cannabis use among younger and older age groups in Australia between 2001 and 2019. Cannabis use substantially decreased among the youngest age group (14-17 s) but modestly increased among older people (55-74 s).

Prevalence of alcohol use and the interventions needed among adults: A community study in a rural area in South India

Background:

The health issues and social problems associated with alcohol use are well known. This study seeks to identify the prevalence of alcohol consumption and dependence among alcohol users in a rural area of Trivandrum district.

Objectives:

To assess the prevalence of alcohol use among adults of Nellanad Panchayat, a rural area in Trivandrum, Kerala, to find out the interventions required among the alcohol users, and to identify persons with harmful and hazardous use of alcohol using AUDIT.

Settings and Design:

Cross-sectional study in Nellanad Panchayat, Trivandrum district, Kerala.

Methods and Materials:

A cross-sectional study was carried out among 1545 residents in Nellanad Panchayat, a rural area in Kerala, by interviewing adults with the help of a questionnaire. Data were analyzed using SPSS.

Results:

The overall prevalence of current alcohol use was 146 (9.5%). The prevalence among males was 143 (18.3%) and females was 3 (0.4%). ASSIST scores showed that 99 (50%) of ever users required health education, 74 (37.8%) required counseling, whereas 23 (11.7%) required de-addiction.

Conclusions:

Among males, the alcohol consumption is still as high as 18.3%. The most important factor affecting alcohol use is peer pressure. Health education is the most required intervention to reduce burden of alcohol use.

The pattern of alcohol use and its relationship with consequences among problem alcohol users: A community-based cross-sectional study from India

BACKGROUND

Pattern of drinking has a strong bearing on alcohol-related negative consequences. Very few studies from India have assessed this relationship using any standardized instrument.

AIM

The current study aims to assess the relationship between pattern of alcohol use and negative consequences among problem alcohol users using a standardized instrument.

MATERIALS AND METHODS

This cross-sectional, observational study using snowball sampling technique was conducted among 75 participants in an urban slum of a metropolitan city of India. Screening of the participants was done by the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test (WHO-ASSIST). Alcohol use details and alcohol-related adverse consequences were obtained by a semi-structured questionnaire and Drinker Inventory of Consequences (DrInC) inventory, respectively. Descriptive statistics, Chi-square test, and logistic regression test were used to analyze the data.

RESULTS

There was a significant association between high total DrInC score and ≥3 subscale scores with employment status, percentage of total family income spent on alcohol, source of income to procure alcohol, amount of alcohol, morning drinking, alcohol use for relaxation, and drinking throughout the day (Chi-square test). Age ≤35 years, current unemployment/part-time employment state, spending ≥25% of total family income on alcohol, family history, and drinking throughout the day were more likely to have high total DrInC score and ≥2 subscale scores (logistic regression analysis).

CONCLUSION

A large proportion of the participants were suffering significantly from alcohol-related consequences but still were not receiving any treatment. It emphasizes the need for more epidemiological studies in this area for its treatment and policy-level implication.

Social Inequalities in Harmful Drinking and Alcohol-Related Problems Among Swedish Adolescents

Aims

The study aims to examine how socio-economic status (SES) among youth is related to binge-drinking and alcohol-related problems using three SES indicators: (i) SES of origin (parental education level), (ii) SES of the school environment (average parental education level at student’s school) and (iii) SES of destination (academic orientation).

Methods

Cross-sectional data on upper secondary students (n= 4448) in Sweden. Multilevel logistic and negative binomial regression were used to estimate the relationship between each SES indicator and binge-drinking and alcohol-related problems, respectively.

Results

Only SES of destination was significantly associated with binge-drinking, with higher odds for students in vocational programmes (OR= 1.42, 95% CI= 1.13–1.80). For the second outcome, SES of destination (rr=1.25; 95%CI=1.08–1.45) and SES of the school environment (rr=1.19, 95% CI=1.02–1.39) indicated more alcohol-related problems in vocational programmes and in schools with lower-educated parents. After adjustment for drinking patterns, the relationship remained for SES of the school environment, but became non-significant for SES of destination.

Conclusion

Our results suggest that the SES gradient among youth is stronger for alcohol-related problems than for harmful drinking. By only focusing on SES differences in harmful alcohol use, researchers may underestimate the social inequalities in adverse alcohol-related outcomes among young people. Our findings also support the notion that the environment young people find themselves in matters for social inequalities in alcohol-related harm.

The changing patterns and correlates of population-level polysubstance use in Australian youth: a multi-group latent class analysis of nationally representative samples spanning 12 years

AIMS

To (1) identify population-level classes of polysubstance use among young Australians between 2004 and 2016, (2) test if these classes changed over the same period, in terms of class prevalence and probabilities of substance use within each class, and (3) identify demographic and health-related correlates of polysubstance use.

DESIGN

Repeated cross-sectional nationally representative household surveys.

SETTING

All Australian states/territories.

PARTICIPANTS

Young adult samples (aged 18-30 years; 58% females) from the National Drug Strategy Household Surveys (n = 20 350) MEASUREMENTS: Outcomes were the extent of past-year use of 10 licit (e.g. alcohol), and illicit substances (e.g. cannabis) were used to derive polysubstance use classes. The correlates were gender, age, psychological distress, general health, language background, personal income, education level, remoteness of residence and socio-economic index for area of residence.

FINDINGS

Three polysubstance use classes were consistently identified between 2004 and 2016 (SSABIC: 188349): minimal users (MU, ~60%), mainly tobacco, alcohol and cannabis users (TAC, ~30%) and extended range polysubstance users (POLY, ~10%). There were substantial changes in use of different substances within each class over the study period. For example, smoking decreased in all classes (P < 0.05), while harmful alcohol use only decreased in the first two classes (P < 0.05). Factors associated with TAC and POLY were similar over the study period. These included: being male and having an English-speaking background, a high level of psychological distress, suboptimal health and high personal income. Living in an affluent area was associated with reduced likelihood of being TAC, but an increased likelihood of being POLY.

CONCLUSION

At the population-level among young Australians between 2004 and 2016, six in 10 did not engage in polysubstance use; four in 10 used a limited range of substances (mainly alcohol, tobacco and cannabis) and one in 10 used an extended range of substances. Over time, the types of substance within the extended polysubstance use class changed substantially.

Alcohol Consumption Frequency of Parents and Stress Status of Their Children: Korea National Health and Nutrition Examination Survey (2007-2016)

Background: The effect of stress on mental health has been increasingly acknowledged. Drinking habits are closely inter-related with stress and each affects the other. However, only limited studies addressed the effects of alcohol consumption on family members apart from spouses. The purpose of this study is to better understand the relationship between parent drinking frequency and their children’s self-reported stress. Methods: Data was collected from the Korean National Health and Nutrition Examination Survey (K-NHANES) conducted during 2007–2016. Respondents were divided into three groups: children (n = 3796), maternal (n = 22,418), and paternal (n = 16,437). After merging the children and parents data sets, we identified the final study population of 3017 and performed binary logistic regression. Results: We found that the odds of high stress cognition was 1.58-fold higher for children who have heavy drinking mother (95% CI: 1.14–2.19) and 1.45-fold higher for those who have heavy drinking father (95% CI: 1.06–1.99). In a subgroup analysis, children whose household income level was Q1 and maternal occupation was white collar showed a statistically significant association of high stress with parental drinking frequency. Conclusions: Parental drinking frequency negatively impacts stress in the children of drinkers. We suggest providing support care for children in vulnerable environments to improve their stress levels.

Drinking patterns and the distribution of alcohol-related harms in Ireland: evidence for the prevention paradox

Background

According to the prevention paradox, the majority of alcohol-related harms in the population occur among low-to-moderate risk drinkers, simply because they are more numerous in the population, although high-risk drinkers have a higher individual risk of experiencing alcohol-related harms. In this study we explored the prevention paradox in the Irish population by comparing alcohol-dependent drinkers (high-risk) to low-risk drinkers and non-dependent drinkers who engage in heavy episodic drinking (HED).

Methods

Data were generated from the 2013 National Alcohol Diary Survey (NADS), a nationally representative cross-sectional survey of Irish adults aged 18–75. Data were available for 4338 drinkers. Respondents dependent on alcohol (as measured by DSM-IV criteria), respondents who engaged in monthly HED or occasional HED (1–11 times a year) and low-risk drinkers were compared for distribution of eight alcohol-related harms.

Results

Respondents who were dependent on alcohol had a greater individual risk of experiencing each harm (p < .0001). The majority of the harms in the population were accounted for by drinkers who were not dependent on alcohol. Together, monthly and occasional HED drinkers accounted for 62% of all drinkers, consumed 70% of alcohol and accounted for 59% of alcohol-related harms.

Conclusions

Our results indicate that the majority of alcohol consumption and related harms in the Irish population are accounted for by low- and moderate-risk drinkers, and specifically by those who engage in heavy episodic drinking. A population-based approach to reducing alcohol-related harm is most appropriate in the Irish context. Immediate implementation of the measures in the Public Health (Alcohol) Act (2018) is necessary to reduce alcohol-related harm in Ireland.

Correlates of electronic cigarette use in the general population and among smokers in Australia - Findings from a nationally representative survey

AIMS

In Australia, sales of nicotine containing electronic cigarettes (also known as e-cigarette) are banned unless approved as a therapeutic good. The aims of this study were to estimate the prevalence of e-cigarette use and its correlates in Australia using a nationally representative survey.

METHOD

We analysed data from the largest drug use survey in Australia (the National Drug Strategy Household Survey [NDSHS]; N = 22,354).

RESULTS

We estimated that 227,000 Australians (1.2% of the population) were current e-cigarettes users, and 97,000 (0.5%) used them daily. Individuals who were male, younger, had higher level of psychological distress, and smoked were more likely to use electronic cigarettes. Among smokers, an intention to quit and reduction in smoking was associated with experimentation and daily use of e-cigarette, but not with occasional use. Recent quitting was associated with daily use.

CONCLUSION

Overall, the prevalence of e-cigarette use was low in 2016 in Australia. Smoking status was the strongest correlates of e-cigarette use. Patterns of vaping were differentialy associated with an intention to quit smoking, smoking reduction and recent quitting. Some smokers may attempt to use e-cigarettes to cut-down their tobacco use, and those who vaped daily were mostly likely to be recent quitters.

Students Who Limit Their Drinking, as Recommended by National Guidelines, Are Stigmatized, Ostracized, or the Subject of Peer Pressure: Limiting Consumption Is All But Prohibited in a Culture of Intoxication

There is an unquestionable need to address drinking patterns in subcultures where excessive drinking is normative. Regulatory bodies advocate moderating alcohol consumption but it is unclear whether individuals have agency to do so, particularly when excessive consumption is the norm. This study aimed to address this gap by examining student’s perceptions of limiting consumption, as recommended by government guidelines, in one university in New Zealand. Using a qualitative social science approach, university students surveyed and interviewed their heavy-drinking peers (n = 201) to investigate perceptions of 3 drinking behaviors (Heavy, Moderation, and Abstinence). Thematic analysis revealed that students who drink heavily are labeled positively and viewed as sociable (Dr Froth, Liver of Steel, Trooper, Champion, Hero, Good Alcoholic, popular, a friend). Students who limit drinking, on the other hand, were viewed similar to those who abstain, labeled using explicit, emotive, and derogative terminology (eg, Fag, Vagina, Grandma, Weirdo, Coward, Killjoy) and excluded, ostracized, or the subject of peer pressure. They were also expected to provide a justification for moderating their drinking (eg, being an athlete, broke). Although individuals who moderated their consumption were perceived to have strong willpower and maturity (eg, self-aware, brave, sophisticated), these positive attributes were mentioned less frequently and involved less emotive language than were labels linking moderation to a negative social identity. The method employed in this study provided a frank insight into a student culture of intoxication and the barriers facing students who try to drink in moderation. Our findings reveal that limiting consumption, even occasionally, threatens students’ social identity and inclusion in the student drinking culture. These results suggest that individualistic harm minimization strategies are unlikely to be effective. Instead, the findings underscore the need to develop alternative cultures emphasizing extracurricular activities which may facilitate students’ agency to go against the norm and moderate their drinking.

Socio-economic differentials in cannabis use trends in Australia

AIM

To test if the degree of change in cannabis use between 2001 and 2013 differed according to socio-economic status.

DESIGN

Repeated cross-sectional household surveys that were nationally representative.

SETTING

Australia.

PARTICIPANTS

Adult samples from the 2001 and 2013 National Drug Strategy Household Surveys (n = 23 642 in 2001 and n = 21 353 in 2013), the largest nationally representative survey on drug use in Australia.

MEASUREMENTS

Frequency of cannabis use coded as daily use, weekly use, less than weekly use and non-current use; socio-economic status (SES) as measured by personal income and educational level.

FINDING

There were significant differences in changes to levels of cannabis use between SES groups. Among participants who completed high school, the probability of daily use decreased from 0.014 to 0.009 (P < 0.001), and the probability of weekly use decreased from 0.025 to 0.017 (P < 0.001). These probabilities remained stable for participants who did not complete high school. The probability of weekly cannabis use decreased from 0.032 to 0.023 among participants with middle level income (P = 0.004), and from 0.021 to 0.013 among those with high income (P = 0.005). There were no significant changes in these probabilities among those with low income (0.026 in 2001 and 0.032 in 2013; P = 0.203).

CONCLUSION

The decline in cannabis use in Australia from 2001 to 2013 occurred largely among higher socio-economic status groups. For people with lower income and/or lower education, rates of frequent cannabis use remained unchanged.

Experience-Induced Change of Alcohol-Related Risk Perception in Patients with Alcohol Use Disorders

The role of alcohol-related risk perception for effective treatment of alcohol use disorders (AUD) is still unclear. The present study on 101 alcohol-dependent patients undergoing a 10-week AUD treatment protocol investigated the relationship between alcohol-related risk perception and alcohol use with the hypotheses that (1) risk perception changes across treatment, (2) changes vary with treatment-related experiences of abstinence/relapse indicating ‘risk reappraisal,’ and (3) adjustment of perceived own vulnerability according to ‘risk reappraisal hypothesis’ predicts abstinence during follow-up. Abstinence during treatment was related to a decrease, and relapse during treatment to a slight increase in perceived own risks. Abstinence during the 3-month follow-up varied with experience-induced risk reappraisal. The results show an impact of risk reappraisal on alcohol use and hence advocate a focus on risk reappraisal in AUD treatment.

More Drinking, More Problems-Stable Association Between Alcohol Consumption and Harm Among Swedish Youth 1995-2012

Aims

Alcohol consumption among Swedish youth increased during the 1990s. In the following decade, levels declined coinciding with a reduction in the prevalence of self-reported alcohol-related harm. We examine how the trend in self-reported alcohol-related problems among young Swedish alcohol consumers has followed the trend in alcohol consumption during 1995-2012, and test whether the strength of the association between self-reported alcohol consumption and alcohol-related problems within individuals is inversely proportional to the overall level of consumption among youth.

Methods

The study was based on a representative survey on alcohol and drug habits among ninth-year students, consisting of current alcohol consumers (n = 68 863), 1995-2012. Negative binominal regression models were used to estimate the relationship between three consumption variables (average volume of consumption, binge drinking and heavy drinking) and self-reported alcohol-related problems.

Results

The prevalence of binge drinking showed a greater association with self-reported alcohol-related problems than did overall mean consumption. No noticeable variation in the strength of the individual-level alcohol and harm relationship was found over the study period. We found no significant interaction between the individual alcohol use measures and overall mean youth consumption.

Conclusion

We found no signs of normalization; on the contrary, young alcohol consumers suffer about the same number of self-reported negative consequences from their drinking, regardless of the level of overall youth consumption. The study also suggests that binge drinking rather than overall consumption is the main factor that influences the development of self-reported problems experienced among young alcohol consumers.

Short summary

Young alcohol consumers suffer about the same number of self-reported negative consequences from their drinking, regardless of the level of overall mean consumption in the youth population. Binge drinking consumption appears to be the main factor influencing the development of self-reported alcohol-related problems among young alcohol consumers.

Involvement in alcohol-related verbal or physical aggression. Does social status matter?

Introduction

–The analyses (1) assessed the association between social status variables and aggression when controlling for volume of alcohol consumption and episodic heavy drinking (EHD), (2) tested whether social status moderates the association between volume or EHD and verbal as well as physical aggression, and (3) investigated whether EHD moderates the effect of volume on aggression.

Methods

Swedish Alcohol Monitoring Survey (2003 to 2011); N=104,316 current drinkers; response rate: 51 to 38%. Alcohol-related aggression was defined as involvement in a quarrel or physical fight while drinking. Social status was defined as the highest education, monthly income and marital status.

Results

The associations between social status variables and aggression showed mixed results. Verbal aggression was associated with education in males and with marital status in both genders. Physical aggression was associated with education in both genders. No associations with aggression were found for income. With few exceptions, these associations remained significant when controlling for drinking patterns; social status did not moderate the association between drinking and aggression; EHD moderated the effect of volume on physical aggression in males.

Conclusions

Groups of lower educated and non-married individuals experience verbal or physical aggression over and above different levels of consumption. Individual differences in aggression vulnerability rather than differences in aggression predisposition account for higher risks of aggression in these groups.

Binge drinking and associated factors among adolescents in a city in southeastern Brazil: a longitudinal study

Abstract: The aim of this study was to investigate changes in the frequency of binge drinking and associated factors in the city of Belo Horizonte, Minas Gerais State, Brazil. The sample consisted of 436 adolescents. Data collection involved the Alcohol Use Disorders Identification Test and the Alcohol, Smoking and Substance Involvement Screening Test. Ordinal logistic regression was used in the multivariate analysis. An increase in the frequency of binge drinking was found among adolescents who lived in areas of greater social vulnerability (OR = 1.64; 95%CI: 1.01-2.68), those whose mothers consumed alcoholic beverages (OR = 1.75; 95%CI: 1.05-2.92), those whose fathers consumed alcoholic beverages (OR = 2.02; 95%CI: 1.11-3.68), those with an increased risk of tobacco use (OR = 2.82; 95%CI: 1.07-7.42) and those who attended religious services (OR = 2.10; 95%CI: 1.30-3.38). Knowledge regarding factors associated with a change in the frequency of binge drinking among adolescents can assist in the establishment of public policies directed at health promotion and the prevention of adverse health conditions.

Trend in alcohol use in Australia over 13 years: has there been a trend reversal?

BACKGROUND

Skog's collectivity theory of alcohol consumption predicted that changes in alcohol consumption would synchronize across all types of drinkers in a population. The aim of this paper is examine this theory in the Australian context. We examined whether there was a collective change in alcohol use in Australia from 2001 to 2013, estimated alcohol consumption in non-high risk and high risk drinkers, and examined the trends in alcohol treatment episodes.

METHODS

Data from the 2001-2013 National Drug Strategy Household Surveys (N = 127,916) was used to estimate the prevalence and alcohol consumption of abstainers, high risk drinkers and frequent heavy episodic drinkers. Closed treatment episodes recorded in the Alcohol and Other Drug Treatment Services National Minimum Dataset (N = 608,367) from 2001 to 2013 were used to examine the trends of closed alcohol treatment episodes.

RESULTS

The prevalence of non-drinkers (abstainers) decreased to the lowest level in 2004 (15.3 %) and rebounded steadily thereafter (20.4 % in 2013; p < .001). Correspondingly, the per capita consumption of high risk drinkers (2 standard drinks or more on average per day) increased from 20.7 L in 2001 to peak in 2010 (21.5 L; p = .020). Non-high risk drinkers' consumption peaked in 2004 (2.9 L) and decreased to 2.8 L in 2013 (p < .05). There were decreases in alcohol treatment episodes across nearly all birth cohorts in recent years.

CONCLUSION

These findings are partially consistent with and support Skog's collectivity theory. There has been a turnaround in alcohol consumption after a decade-long uptrend, as evident in the collective decreases in alcohol consumption among nearly all types of drinkers. There was also a turnaround in rate of treatment seeking, which peaked at 2007 and then decreased steadily. The timing of this turnaround differs with level of drinking, with non-high risk drinkers reaching its peak consumption in 2004 and high risk drinkers reaching its peak consumption in 2010.

Trends in binge drinking in Canada from 1996 to 2013: a repeated cross-sectional analysis

BACKGROUND

Heavy drinking is a major factor in morbidity and mortality worldwide. Little information is available on trends in Canada regarding alcohol abuse. We sought to estimate abstinence, binge drinking and alcohol intake exceeding low-risk drinking guidelines in the Canadian population from 1996 to 2013.

METHODS

The data sources for this analysis were a series of cross-sectional national health surveys of the Canadian population carried out by Statistics Canada between 1996 and 2013. These were cross-sectional files from the National Population Health Surveys of 1996 and 1998, plus the Canadian Community Health Surveys from 2000 to 2013. Respondents were aged 18 years and older.

RESULTS

The proportion of binge drinkers increased steadily from 13.7% (95% confidence interval [CI] 13.2%-14.2%) in 1996 to 19.7% (95% CI 19.1%-20.3%) in 2013. The corresponding proportions for men were 20.8% (95% CI 19.9%-21.7%) in 1996, and 25.7% (95% CI 24.7%-26.6%) in 2013; for women, these proportions were 6.9% (95% CI 6.4%-7.5%) in 1996, and 13.8% (95% CI 13.1%-14.5%) in 2013. No significant increases were seen in the proportion of people who exceeded low-risk drinking guidelines or of abstainers during the same period.

INTERPRETATION

The rate of self-reported binge drinking in Canada has increased from 1996 to 2013, relatively more so among women than among men. No evidence of an increase in the proportion of people exceeding low-risk drinking guidelines or of abstainers was seen during the same period. These results suggest that binge drinking is of particular concern regarding intervention strategies aimed at improvement of public health.

Different versions of the Alcohol Use Disorders Identification Test (AUDIT) as screening instruments for underage binge drinking

BACKGROUND

The changes experienced in recent years in the conceptualization of binge drinking (BD) make it necessary to revise the usefulness of the existing instruments for its detection among minors. The AUDIT and its abbreviated versions have shown their utility in different populations and consumption ranges, but there has been little research into their use in the detection of BD among adolescents. This study tests the capacity of the AUDIT, AUDIT-C and AUDIT-3 to identify BD adolescents, indicating the optimal cut-off points for each sex.

METHODS

High school students self-administered the AUDIT and completed a weekly self-report of their alcohol intake. BD is classified into different groups according to parameters like the quantity consumed and its frequency in the past six months, adjusting the cut-off points for each case.

RESULTS

The results obtained with a sample of 634 adolescents (15-17 years old/52.2% female) indicate that cut-off points of 4 on the AUDIT and 3 on the AUDIT-C show the best fit. Dividing the sample by sexes, the AUDIT and the AUDIT-C would detect BD males with scores of 5 and 4, respectively (with the AUDIT-C being more sensitive), and BD females with a score of 3 on both (the more sensitive being the AUDIT).

CONCLUSIONS

All three versions are adequate to classify BD adolescents but none of them made it possible to safely differentiate binge drinkers with different consumption intensities.

Independent and combined associations of risky single-occasion drinking and drinking volume with alcohol use disorder: Evidence from a sample of young Swiss men

BACKGROUND

Risky single-occasion drinking (RSOD) is a prevalent and potentially harmful alcohol use pattern associated with increased alcohol use disorder (AUD). However, RSOD is commonly associated with a higher level of alcohol intake, and most studies have not controlled for drinking volume (DV). Thus, it is unclear whether the findings provide information about RSOD or DV. This study sought to investigate the independent and combined effects of RSOD and DV on AUD.

METHODS

Data were collected in the longitudinal Cohort Study on Substance Use Risk Factors (C-SURF) among 5598 young Swiss male alcohol users in their early twenties. Assessment included DV, RSOD, and AUD at two time points. Generalized linear models for binomial distributions provided evidence regarding associations of DV, RSOD, and their interaction.

RESULTS

DV, RSOD, and their interaction were significantly related to the number of AUD criteria. The slope of the interaction was steeper for non/rare RSOD than for frequent RSOD.

CONCLUSIONS

RSOD appears to be a harmful pattern of drinking, associated with increased AUD and it moderated the relationship between DV and AUD. This study highlighted the importance of taking drinking patterns into account, for both research and public health planning, since RSO drinkers constitute a vulnerable subgroup for AUD.

Does a Change Over All Equal a Change in All? Testing for Polarized Alcohol Use Within and Across Socio-Economic Groups in Germany

AIMS

This study aimed at testing whether drinking volume and episodic heavy drinking (EHD) frequency in Germany are polarizing between consumption levels over time. Polarization is defined as a reduction in alcohol use among the majority of the population, while a subpopulation with a high intake level maintains or increases its drinking or its EHD frequency. The polarization hypothesis was tested across and within socio-economic subgroups.

METHOD

Analyses were based on seven cross-sectional waves of the Epidemiological Survey of Substance Abuse (ESA) conducted between 1995 and 2012 (n = 7833-9084). Overall polarization was estimated based on regression models with time by consumption level interactions; the three-way interaction with socio-economic status (SES) was consecutively introduced to test the stability of effects over socio-economic strata. Interactions were interpreted by graphical inspection.

RESULTS

For both alcohol use indicators, declines over time were largest in the highest consumption level. This was found within all SES groups, but was most pronounced at low and least pronounced at medium SES.

CONCLUSION

The results indicate no polarization but convergence between consumption levels. Socio-economic status groups differ in the magnitude of convergence which was lowest in medium SES. The overall decline was strongest for the highest consumption level of low SES.

Promoting responsible drinking? A mass media campaign affects implicit but not explicit alcohol-related cognitions and attitudes

OBJECTIVES

Rigorous tests are not usually applied to determine whether mass media campaigns that promote responsible drinking are useful, that is whether they lead to responsible drinking or not. In two experiments, we investigated the effectiveness of a mass media campaign that runs in Germany since 2009. This campaign used posters, which emphasized negative alcohol-related outcome expectancies and challenged the positive expectancies. Based on models of alcohol use, we investigated the influence of the campaign on alcohol-related outcome expectancies, implicit and explicit attitudes, and drinking intentions.

DESIGN

In Experiment 1, we investigated alcohol-related outcome expectancies via ratings and response latencies among 81 young adult light drinkers. Employing an affective priming task, Experiment 2 was designed to assess implicit attitudes before and after mass media campaign exposure among 83 young adult light drinkers. In both experiments, the effects of the posters were investigated before and after poster exposure as well as compared to a control group.

RESULTS

Experiment 1 revealed that the campaign affected only the implicit associations of young adult drinkers, whereas explicit outcome expectancies remained unaffected. Experiment 2 showed that implicit attitudes towards alcohol were turned into more negative ones, but explicit attitudes as well as drinking intentions were not influenced.

CONCLUSIONS

The mass media campaign was deemed effective even though its influence occurred on an implicit level. This research highlights the need for experimental investigations of mass media campaigns. Reasons that the findings were obtained on an implicit but not on an explicit level are discussed.

Addiction research centres and the nurturing of creativity: IFT Institut für Therapieforschung in Munich, Germany

This paper describes the history and current structure of the Institut für Therapieforschung (IFT) [Institute for Therapy Research] in Munich, as well as major research topics and factors which might contribute to a creative structure and atmosphere for innovative research in the addiction field. The institute was founded in 1973 as a non-profit non-governmental organization (NGO) with a focus on applied research. Starting with behaviour therapy-based development and evaluation of programmes for alcohol, illicit drugs and smoking and the evaluation of treatment services, the institute gradually expanded its topics, covering prevention (1985) and epidemiology and policy evaluation (1990), and participated throughout this period in the development of guidelines and screening, diagnostic and clinical instruments. Later, the IFT tried to bridge the gap between basic sciences, applied research, health-care services and health policy, with a network of national and international contacts, including its own university engagements and collaborations with foreign research groups and national and European Union (EU) agencies. Possible creativity-promoting factors on the institutional and individual levels are discussed, e.g. the collaboration of experienced senior researchers with carefully selected innovative doctoral students, considerable in-house and external training of young researchers and the early participation and presentation of their work at international conferences, independence from stakeholders in the field and the refusal of project funds which require external clearance of publications.

Does Drinking Location Matter? Profiles of Risky Single-Occasion Drinking by Location and Alcohol-Related Harm among Young Men

In adolescents and young adults, acute consequences like injuries account for a substantial proportion of alcohol-related harm, especially in risky single-occasion (RSO) drinkers. The primary aim of the study was to characterize different drinking profiles in RSO drinkers according to drinking locations and their relationship to negative, alcohol-related consequences. The sample consisted of 2746 young men from the Cohort Study on Substance Use Risk Factors who had reported drinking six or more drinks on a single-occasion at least monthly over the preceding 12 months. Principal component analysis on the frequency and amount of drinking at 11 different locations was conducted, and 2 distinguishable components emerged: a non-party-dimension (loading high on theater/cinema, sport clubs, other clubs/societies, restaurants, and sport events) and a party-dimension (loading high on someone else’s home, pubs/bars, discos/nightclubs, outdoor public places, special events, and home). Differential impacts of drinking location profiles were observed on severe negative alcohol-related consequences (SAC). Relative to those classified as low or intermediate in both dimensions, no significant difference experiencing SAC was found among those who were classified as high in the non-party-dimension only. However, those who were classified as high in the party-dimension alone or in both dimensions were more likely to experience SAC. These differential effects remained after adjusting for alcohol consumption (volume and risky single-occasion drinking), personality traits, and peer-influence [adjusted OR = 0.83 (0.68–1.02), 1.57 (1.27–1.96), and 1.72 (1.23–2.41), respectively], indicating independent effects of drinking location on SAC. The inclusion of sociodemographic factors did not alter this association. The fact that this cluster of party-dimension locations seems to predispose young men to experiencing SAC has important implications for alcohol control policies.

Estimation of usual occasion-based individual drinking patterns using diary survey data

BACKGROUND

In order to successfully address excessive alcohol consumption it is essential to have a means of measuring the drinking patterns of a nation. Owing to the multi-dimensional nature of drinking patterns, usual survey methods have their limitations. The aim of this study was to make use of extremely detailed diary survey data to demonstrate a method of combining different survey measures of drinking in order to reduce these limitations.

METHODS

Data for 1724 respondents of the 2000/01 National Diet and Nutrition Survey was used to obtain a drinking occasion dataset, by plotting the respondent's blood alcohol content over time. Drinking frequency, level and variation measures were chosen to characterise drinking behaviour and usual behaviour was estimated via statistical methods.

RESULTS

Complex patterns in drinking behaviour were observed amongst population subgroups using the chosen consumption measures. The predicted drinking distribution combines diary data equivalent coverage with a more accurate proportion of non-drinkers.

CONCLUSIONS

This statistical analysis provides a means of obtaining average consumption measures from diary data and thus reducing the main limitation of this type of data for many applications. We hope that this will facilitate the use of such data in a wide range of applications such as risk modelling, especially for acute harms, and burden of disease studies.

Evaluation of drinking patterns and their impact on alcohol-related aggression: a national survey of adolescent behaviours

Background

Although there have been a wide range of epidemiological studies examining the impact of patterns of alcohol consumption among adolescents, there remains considerable variability in both defining these patterns and the ability to comprehensively evaluate their relationship to behavioural patterns. This study explores a new procedure for defining and evaluating drinking patterns and integrating well-established indicators. The composite measure is then used to estimate the impact of these patterns on alcohol-related aggressive behaviour among Italian adolescents.

Methods

Data were collected as part of the 2011 European School Survey Project on Alcohol and other Drugs (ESPAD). A national sample of 14,199 students aged 15–19 years was collected using an anonymous, self-administered questionnaire completed in a classroom setting. Drinking patterns were established using principal component analysis. Alcohol-related aggression was analysed as to its relationship to patterns of drinking, behaviour of friends towards alcohol use, substance use/abuse, school performance, family relationships and leisure activities.

Results

Several specific drinking patterns were identified: “Drinking to Excess” (DE), “Drinking with Intoxication” (DI) and “Drinking but Not to Excess” (DNE). A higher percentage of males were involved in alcohol-related aggression compared with females. In males, the DE and DI patterns significantly increased the likelihood of alcohol-related aggression, whereas the DNE pattern was negatively associated. Similar results were found in females, although the DI pattern was not significantly associated with alcohol-related aggression. Overall, cigarette smoking, illegal drug use, truancy, limited parental monitoring, frequent evenings spent outside of the home and peer influence associated strongly with alcohol-related aggression.

Conclusions

Our findings suggest that drinking patterns, as uniquely monitored with an integrated metric, can: 1) explain drinking habits better than commonly used indicators of alcohol use and 2) provide a better understanding of behavioural risks such as alcohol-related aggression. Environmental background also appears to strongly associate with this type of aggressive behaviour.

Substanzkonsum und substanzbezogene Störungen in Deutschland im Jahr 2012

Ziel: Untersucht wurden Umfang, Konsummuster und Störungen im Zusammenhang mit dem Gebrauch von Alkohol, Tabak, illegalen Drogen und Medikamenten. Methodik: Die Stichprobe des Epidemiologischen Suchtsurveys (ESA) 2012 wurde zufällig aus den Einwohnermelderegistern gezogen und umfasste 9084 Personen im Alter zwischen 18 und 64 Jahren. Die Befragung erfolgte schriftlich, telefonisch bzw. über das Internet; die Antwortrate lag bei 53.6 %. Ergebnisse: Bezogen auf die letzten 30 Tage zeigten 57.3 % der Befragten einen risikoarmen und 14.2 % einen riskanten Alkoholkonsum. Insgesamt 30.2 % gaben an, in diesem Zeitraum geraucht zu haben. In den letzten 12 Monaten haben 4.5 % der Befragten Cannabis, 0.8 % Kokain und 0.7 % Amphetamine konsumiert. Schmerzmittel waren die am häufigsten eingenommenen Medikamente (12-Monats-Prävalenz: 61.9 %). Schätzungen zur Substanzabhängigkeit nach DSM-IV ergaben Prävalenzwerte von 3.4 % für Alkohol, 10.8 % für Tabak, 0.5 % für Cannabis, 0.2 % für Kokain, 0.1 % für Amphetamine und 3.4 % für Schmerzmittel. Schlussfolgerungen: Die hohe Verbreitung psychischer Störungen durch Alkohol und Tabak macht die Dringlichkeit der Umsetzung effizienter Präventionsmaßnahmen deutlich. Störungen im Zusammenhang mit Medikamenten sollten stärker beachtet werden.

Predictors of binge drinking in adolescents: ultimate and distal factors - a representative study

BACKGROUND

As epidemiological surveys have shown, binge drinking is a constant and wide-spread problem behavior in adolescents. It is not rare to find that more than half of all adolescents engage in this behavior when assessing only the last 4 weeks of time independent of the urbanity of the region they live in. There have been several reviews on predictors of substance consumption in adolescents in general, but there has been less high quality research on predictors of binge drinking, and most studies have not been theoretically based. The current study aimed to analyze the ultimate and distal factors predicting substance consumption according to Petraitis' theory of triadic influence. We assessed the predictive value of these factors with respect to binge drinking in German adolescents, including the identification of influence direction.

METHODS

In the years 2007/2008, a representative written survey of N = 44,610 students in the 9th grade of different school types in Germany was carried out (net sample). The return rate of questionnaires was 88% regarding all students whose teachers or school directors had agreed to participate in the study. In this survey, prevalence of binge drinking was investigated as well as potential predictors from the social/interpersonal, the attitudinal/environmental, and the intrapersonal fields (3 factors of Petraitis). In a multivariate logistic regression analysis, these variables were included after testing for multicollinearity in order to assess their ability to predict binge drinking.

RESULTS

Prevalence of binge drinking in the last 30 days was 52.3% for the surveyed adolescents with a higher prevalence for boys (56.9%) than for girls (47.5%). The two most influential factors found to protect against binge drinking with p < .001 were low economic status and importance of religion. The four most relevant risk factors for binge drinking (p < .001) were life-time prevalence of school absenteeism/truancy, academic failure, suicidal thoughts, and violence at school in the form of aggressive behavior of teachers. The model of Petraitis was partly confirmed for Binge Drinking in German adolescents and the direction of influence factors was clarified.

CONCLUSIONS

Whereas some of the risk and protective factors for binge drinking are not surprising since they are known for substance abuse in general, there are two points that could be targeted in interventions that do not focus on adolescents alone: (a) training teachers in positive, reassuring behavior and constructive criticism and (b) a focus on high risk adolescents either because they have a lack of coping strategies when in a negative mood or because of their low academic achievement in combination with absenteeism from school.

Age, period and cohort analysis of light and binge drinking in Finland, 1968-2008

AIMS

To analyse the effects of age, period and cohort (APC) on light and binge drinking in the general population of Finland over the past 40 years.

METHODS

All analyses were based on six Drinking Habits Surveys between 1968 and 2008 of representative samples of the Finnish population aged between 15 and 69 (n = 16,400). The number of drinking occasions per year involving 1-2 drinks (light) and 4+ or 6+ drinks (binges) was used as a dependent variable in APC modelling. Descriptive cohort profiles and negative binomial models were used to assess the effects of APC.

RESULTS

Descriptive cohort profiles differed for light and binge drinking. No substantial differences were found across cohort profiles for light drinking, while APC modelling predicted declining cohort and increasing period effects. Differences between cohorts were found for binge drinking, with predictions of slightly declining or increasing period and increasing cohort effects.

CONCLUSIONS

Light drinking has increased over time for each cohort, with no substantial differences between cohort profiles. Binge drinking has increased with more recent cohorts and there are distinct differences between cohort profiles, especially among women.

A prospective study of sexual assault and alcohol use among first-year college women

This study prospectively examined the relation between alcohol use and sexual assault in a sample (N = 319) of first-year college women. Both frequency of drinking and frequency of binge drinking were measured. Over the course of their freshman year, 19.3% reported experiencing at least one sexual assault. Frequent binge drinking and frequent drinking predicted a subsequent sexual assault; however, experiencing a sexual assault did not predict changes in alcohol use. Frequent binge drinking demonstrated a stronger association with sexual assault than did frequent drinking. Findings help clarify the relation between alcohol use and sexual assault in college women and call for continued differentiation in assessment of alcohol use.

Surveying the range and magnitude of alcohol's harm to others in Australia

AIMS

This study aims to document the adverse effects of drinkers in Australia on people other than the drinker.

DESIGN

Cross-sectional survey.

SETTING

In a national survey of Australia, respondents described the harmful effects they experienced from drinkers in their households, family and friendship networks, as well as work-place and community settings.

PARTICIPANTS

A randomly selected sample of 2,649 adult Australians.

MEASUREMENTS

Problems experienced because of others' drinking were ascertained via computer-assisted telephone interviews. Respondent and drinker socio-demographic and drinking pattern data were recorded.

FINDINGS

A total of 70% of respondents were affected by strangers' drinking and experienced nuisance, fear or abuse, and 30% reported that the drinking of someone close to them had negative effects, although only 11% were affected by such a person 'a lot'. Women were more affected by someone they knew in the household or family, while men were more affected by strangers, friends and co-workers. Young adults were consistently the most negatively affected across the majority of types of harm.

CONCLUSIONS

Substantial proportions of Australians are affected by other people's drinking, including that of their families, friends, co-workers and strangers. These harms range in magnitude from noise and fear to physical abuse, sexual coercion and social isolation.

Alcohol use and negative consequences among active duty military personnel

AIMS

An examination of alcohol use patterns in the active duty military to determine the relations of drinking levels and self-reported negative outcomes.

DESIGN

A population-based cross-sectional study design using two-stage complex sampling methodology.

SETTING

Paper and pencil surveys were administered anonymously in groups at 64 U.S. military installations worldwide.

PARTICIPANTS

Randomly selected active duty members (28,546) at major military installations representing the total active force, with the exception of recruits, cadets, and incarcerated personnel.

MEASURES

Personnel were classified into five drinking levels ranging from abstainer to heavy drinker based on quantity and frequency of alcohol intake. Negative outcomes were measured as self-reported serious consequences of alcohol use and alcohol-related productivity loss. Risk for other alcohol related problems was assessed by the Alcohol Use Disorders Identification Test (AUDIT).

FINDINGS

Alcohol negative outcomes showed a curvilinear dose-response relationship with drinking levels. Higher levels of drinking were associated with higher rates of alcohol problems, but problem rates were notably higher for heavy drinkers. Heavy alcohol users showed nearly three times the rate of self-reported serious consequences and over twice the rate of self-reported productivity loss than moderate/heavy drinkers. Heavy drinkers also had the highest risk for alcohol problems on the AUDIT. One fifth of military personnel were heavy drinkers and were most likely aged 18 to 35.

CONCLUSIONS

Prevention and clinical interventions should include a major focus on heavy drinkers. Commanders and peers should be trained in recognizing signs of heavy alcohol use and in approaching heavy alcohol users in a way that will foster positive attitudes as opposed to defensiveness and stigma.

Alkoholkonsum und alkoholbezogene Mortalität, Morbidität, soziale Probleme und Folgekosten in Deutschland

Ziel: Ziel dieses Beitrags ist es, einen Überblick über den Alkoholkonsum und die damit verbundenen negativen Konsequenzen in Deutschland zu geben. Methodik: Dargestellt werden Daten zum Alkoholkonsum (Alkoholwirtschaft und Bevölkerungssurveys) sowie zu alkoholbedingter Mortalität (Gesamtsterblichkeit und potenziell verlorene Lebensjahre) und Morbidität (durch Krankheit verlorene Lebensjahre), zu sozialen Folgen (Straftaten, Straßenverkehr und Arbeit) und Folgekosten des Konsums. Ergebnisse: Alkohol war im Jahr 2002 für 48.571 Todesfälle (5,5 % der Gesamtsterblichkeit) in Deutschland verantwortlich, was 970.029 potenziell verlorenen Lebensjahren entspricht. Im Jahr 2004 waren insgesamt 6,2 % der nationalen Belastung durch Krankheit und Verletzungen vom Alkoholkonsum verursacht. Allein die bei den Allgemeinen Ortskrankenkassen (AOK) registrierten alkoholbedingten Arbeitsunfähigkeitstage beliefen sich im Jahr 2008 bei ca. 82.000 Fällen auf 1,09 Mio. Eine Schätzung der durch Morbidität und Mortalität bedingten Gesamtkosten ergab für das Jahr 2002 rund 24 Mrd. Euro (1,16 % des Bruttoinlandsprodukts). Schlussfolgerungen: Die Zahlen zu Umfang und negativen Folgen des Alkoholkonsums unterstreichen die Notwendigkeit der Entwicklung einer umfassenden Alkoholpolitik.

Alcohol consumption and binge drinking in adolescents: comparison of different migration backgrounds and rural vs. urban residence--a representative study

Background

Binge drinking is a constant problem behavior in adolescents across Europe. Epidemiological investigations have been reported. However, epidemiological data on alcohol consumption of adolescents with different migration backgrounds are rare. Furthermore representative data on rural-urban comparison concerning alcohol consumption and binge drinking are lacking. The aims of the study are the investigation of alcohol consumption patterns with respect to a) urban-rural differences and b) differences according to migration background.

Methods

In the years 2007/2008, a representative written survey of N = 44,610 students in the 9^th. grade of different school types in Germany was carried out (net sample). The return rate of questionnaires was 88% regarding all students whose teachers respectively school directors had agreed to participate in the study. Weighting factors were specified and used to make up for regional and school-type specific differences in return rates. 27.4% of the adolescents surveyed have a migration background, whereby the Turkish culture is the largest group followed by adolescents who emigrated from former Soviet Union states. The sample includes seven large cities (over 500,000 inhabitants) (12.2%), independent smaller cities ("urban districts") (19.0%) and rural areas ("rural districts") (68.8%).

Results

Life-time prevalence for alcohol consumption differs significantly between rural (93.7%) and urban areas (86.6% large cities; 89.1% smaller cities) with a higher prevalence in rural areas. The same accounts for 12-month prevalence for alcohol consumption. 57.3% of the rural, re-spectively 45.9% of the urban adolescents engaged in binge drinking in the 4 weeks prior to the survey. Students with migration background of the former Soviet Union showed mainly drinking behavior similar to that of German adolescents. Adolescents with Turkish roots had engaged in binge drinking in the last four weeks less frequently than adolescents of German descent (23.6% vs. 57.4%). However, in those adolescents who consumed alcohol in the last 4 weeks, binge drinking is very prominent across the cultural backgrounds.

Conclusions

Binge drinking is a common problem behavior in German adolescents. Obviously adolescents with rural residence have fewer alternatives for engaging in interesting leisure activities than adolescents living in cities. This might be one reason for the more problematic consumption patterns there. Common expectations concerning drinking behavior of adolescents of certain cultural backgrounds ('migrants with Russian background drink more'/'migrants from Arabic respectively Oriental-Islamic countries drink less') are only partly affirmed. Possibly, the degree of acculturation to the permissive German alcohol culture plays a role here.

Age, Period, and Cohort Effects on Time Trends in Alcohol Consumption in the German Adult Population

Aims: To estimate independent age, period, and cohort effects on time trends in alcohol volume and episodic heavy drinking in Germany. Method: Data from six waves of the German Epidemiological Survey of Substance Abuse (ESA) between 1995 and 2009 were used. The analytical sample comprised n = 34,542 individuals aged 18 to 64 years with at least one drinking occasion in the last 30 days. Alcohol volume was derived from beverage-specific quantity frequency questions. Episodic heavy drinking was specified as the number of days with five or more alcoholic drinks at a single occasion. Results: On average across age and cohort groups, alcohol consumption has considerably declined over the last 15 years. Cohort effects indicate a decline in alcohol volume from the 1940s to the 1970s birth cohort groups and a steep increase in younger cohorts. Moreover, cohorts born after 1980 were found to drink more often to intoxication than older cohorts. Age variations in trends were rather small compared to period and cohort effects. Conclusions: Despite the steady declining trend in alcohol consumption in the German general population, there is a tendency toward riskier drinking patterns among the youngest cohorts. This underlines the need for alcohol policy measures.

Substanzkonsum und substanzbezogene Störungen

Ziel: Untersucht wurden Prävalenzen des Konsums sowie substanzbezogener Störungen von illegalen Drogen, Alkohol, Tabakwaren und Medikamenten. Methodik: Die Stichprobe des Epidemiologischen Suchtsurveys (ESA) 2009 umfasst 8.030 Personen im Alter zwischen 18 und 64 Jahren und wurde in einem zweistufigen Verfahren auf Grundlage der Einwohnermelderegister zufällig gezogen. Die Befragung erfolgte schriftlich, telefonisch bzw. über das Internet und erzielte eine Antwortrate von 50.1 %. Ergebnisse: In den letzten 12 Monaten haben 4.8 % der Befragten Cannabis, 0.8 % Kokain und 0.7 % Amphetamine konsumiert. Bezogen auf die letzten 30 Tage gaben 59.9 % einen risikoarmen und 16.5 % einen riskanten Alkoholkonsum an. Als aktuelle Raucher (30-Tage-Prävalenz) konnten 29.2 % der Befragten klassifiziert werden. Mit einer 12-Monats-Prävalenz von 61.6 % waren Schmerzmittel die am häufigsten eingenommenen Medikamente. Schätzungen zu substanzbezogenen Störungen ergaben für Cannabisabhängigkeit 1.2 % und für Nikotinabhängigkeit 6.3 %. Für problematischen Alkoholkonsum wurden 19.0 % und für problematischen Medikamentengebrauch 4.0 % ermittelt. Schlussfolgerungen: Die Ergebnisse belegen eine hohe gesundheitspolitische Bedeutung des Substanzkonsums in Deutschland. Um negative Konsequenzen des Konsumverhaltens zu vermeiden, sind eine effektive Versorgung behandlungsbedürftiger Personen sowie frühzeitige Präventionsbemühungen erforderlich.

Trends des Substanzkonsums und substanzbezogener Störungen

Ziel: Untersucht wurden Trends des Konsums sowie substanzbezogener Störungen von illegalen Drogen, Alkohol, Tabak und Medikamenten über einen Zeitraum von 15 Jahren (1995–2009). Methodik: Daten liefern sechs Erhebungswellen des Epidemiologischen Suchtsurveys (ESA), die zwischen 1995 und 2009 durchgeführt wurden. Alle Erhebungen erfolgten schriftlich bzw. in einem Mixed-Modus Design und erzielten Antwortraten zwischen 45 und 65 %. Ergebnisse: Die 12-Monats-Prävalenz von Cannabis lag im Jahr 2009 (5.2 %) nach einem Maximum im Jahr 2003 (6.9 %) auf einem niedrigeren Niveau. Die bis zum Jahr 2003 zu beobachtende Verschiebung des Alkoholkonsums (letzte 30 Tage) hin zu weniger riskanten Konsummustern setzte sich in den Erhebungen bis zum Jahr 2009 nicht fort. Dagegen wies die 30-Tage-Prävalenz des Rauchens einen konstanten Rückgang auf und lag 2009 bei 30.3 %. Eine negative Entwicklung zeigte sich im Gebrauch von Schmerzmitteln (letzte 30 Tage), der im Jahr 2009 einen deutlichen Zuwachs aufwies. In Bezug auf Cannabis- und Nikotinabhängigkeit sowie problematischen Alkohol- und Medikamentengebrauch ließen sich keine wesentlichen Veränderungen in den 12-Monats-Prävalenzwerten feststellen. Schlussfolgerungen: Über den gesamten Beobachtungszeitraum ging die höchste Belastung von legalen Drogen aus, gefolgt von Medikamenten und illegalen Drogen. Die weitere Beobachtung von Konsumtrends ist von großer gesundheitspolitischer Bedeutung.

Studiendesign und Methodik des Epidemiologischen Suchtsurveys 2009

Hintergrund: Der Epidemiologische Suchtsurvey (ESA) 2009 untersucht den Konsum und Missbrauch von psychoaktiven Substanzen in der deutschen Allgemeinbevölkerung. Ziel: Beschreibung der Stichprobenziehung, der eingesetzten Instrumente, der Datenerhebung, Ausschöpfung und Gewichtung des Surveys. Durchführung einer Nonresponse- und Modus-Effekt-Analyse. Methodik: Die Stichprobe wurde disproportional zur Verteilung der Geburtskohorten in der Bevölkerung in einem zweistufigen, zufallsgesteuerten Auswahlverfahren aus den Einwohnermelderegistern gezogen. Ergebnisse: Insgesamt nahmen 8.030 Personen (3.731 schriftlich, 3.376 telefonisch und 927 online) im Alter zwischen 18 und 64 Jahren teil. Die Antwortrate betrug 50.1 %. Die verwendete Design- und Poststratifikationsgewichtung erzielte eine Effektivität von 83.5 %. Abweichungen von der Grundgesamtheit bestehen in der gewichteten Stichprobe hinsichtlich Staatsbürgerschaft und Schulbildung. An der telefonischen oder schriftlichen Kurzbefragung nahmen 8 % aller Nichtantworter teil. Die Vergleiche zeigen, dass Nichtteilnehmer seltener Alkohol- und Drogenkonsum berichteten als Teilnehmer. Modus-Effekte deuten im Vergleich zu schriftlich Befragten auf eine geringere Verbreitung von Cannabiskonsum unter telefonisch Befragten und eine geringere Prävalenz von Alkoholkonsum unter Online-Teilnehmern hin. Schlussfolgerungen: Der eingesetzte Methodenmix aus schriftlicher, telefonischer und Online-Befragung wirkte sich positiv auf die Teilnahmebereitschaft aus, was sich in einer gestiegenen Antwortrate im Vergleich zu früheren ESA-Studien zeigt.

Drinking before going out--a predictor of negative nightlife experiences in a German inner city area

OBJECTIVE

The aim of the presented study is to identify target groups for early interventions to reduce negative effects of nightlife alcohol consumption and negative nightlife experiences (e.g. involvement in fights) as well as to examine the consumption patterns and identify the need for further interventions.

METHOD

A cross-sectional survey of 308 persons in a German city centre during night time.

MEASUREMENTS

A questionnaire including questions on basic demographics, alcohol consumed prior to and during a typical night out, drug usage and experiences of the city's nightlife in the previous 12 months.

RESULTS

Two-thirds of the interviewees repeated a hazardous or high alcohol consumption pattern on a night out. We found several predictors for negative nightlife experiences: those who are male, younger than 25, have a low level of education, show higher alcohol consumption (especially before going out), and take illicit drugs are at a particularly great risk of experiencing negative nightlife events.

CONCLUSIONS

We found several factors which increase the risk of experiencing negative effects of alcohol consumption. In particular, drinking before going out seems to be associated with aversive consequences.
