Alcohol's Secondhand Harms in the United States: New Data on Prevalence and Risk Factors

The extent and diversity of harm from the drinking of unknown others in Australia: An analysis of data from during the COVID-19 pandemic

INTRODUCTION

This paper aims to produce a comprehensive estimate of alcohol's harm to others (AHTO) from strangers among Australia adults in 2021. This survey was undertaken during COVID-19 and aims to compare AHTO results with those from 12 years before and identify differences across socio-demographics.

METHODS

Cross-sectional data of 2574 Australian adults were collected in November 2021 via two survey modes: random digit dialling and the Life in Australia™ panel. Questions pertained to harms from the drinking of known and unknown others ('strangers') in the previous 12 months. Multivariable logistic regression is used to analyse differences in the experience of AHTO from strangers across age, gender and other socio-demographics.

RESULTS

Under half of Australian adults reported experiencing AHTO from a stranger (42.2%) during the period of COVID-19. Women were at significantly higher odds of reporting harm than men. Significantly higher percentages of participants aged 18-49 reported harm than those 65 and over. Rates of experience of harm from strangers' drinking varied between different Australian regions. Adults engaging in less frequent risky drinking (less than 4 days a month) reported significantly greater experiences of harm than those not engaging in risky drinking in the past year.

DISCUSSION AND CONCLUSIONS

The current study provides a national estimate of AHTO from strangers in Australia during the COVID-19 pandemic. Finding greater risk of experiencing AHTO from strangers among women than men differs from previous AHTO literature, and further research is required to determine if this is an emerging trend.

Depression, Anxiety, and Coping Strategies Among Farmworkers Exposed to Substance Use at Work

OBJECTIVE

Migrant farmworkers are at an increased risk of experiencing high levels of stress, depression, anxiety, and problematic substance use. Farmworker behavioral health is a predominant concern for agricultural health and safety efforts. While substance use has been found to be a visible part of the work environment among farming populations, there is scarce information about how farmworkers who are exposed to substance use at work are impacted.

METHODS

This exploratory assessment investigated the association between substance use exposure at work and migrant farmworkers' (N = 58) symptoms of depression, anxiety, and coping strategies used. Univariate, bivariate, and regression analyses were conducted to examine data from a survey administered to migrant farmworkers in Southern California's Riverside and Imperial Valley counties.

RESULTS

Exposure to substance use at work was significantly associated with farmworkers reporting more severe symptoms of anxiety (p = .018). We also found that anxiety among farmworkers was significantly related to their experiences of sexual harassment (p = .026), being called names or insulted (p = .05), feeling unsafe (p = .005), having an increased work burden (p = .001), and caring for a colleague (p = .001). Furthermore, as exposure to substance use at work increased, farmworkers reported more severe symptoms of depression (F (1,45) = 7.90, p = .007) and anxiety (F (1,45) = 16.743, p = .001). To cope, the farmworkers in our sample reported using emotion-focused coping strategies most often.

CONCLUSIONS

Substance use exposure at work can affect migrant farmworker health and safety. Addressing and supporting the behavioral health of the entire farming community is warranted.

Descriptive Drinking Norms and Alcohol-Related Negative Consequences: A Moderated Mediation Model Involving Drinking Quantity and Protective Behavioral Strategies

We examined whether drinking quantity mediated the relationship between descriptive drinking norms and alcohol-related negative consequences, and if this was moderated by protective behavioral strategies (PBS) use. Undergraduate students ( n = 538, 78.0% female, mean age = 21.21 [ SD = 3.62]) from three Spanish universities completed a questionnaire. Simple and moderated mediation analyses were conducted. Drinking quantity fully mediated the relationship between descriptive drinking norms and alcohol consequences, and PBS moderated this relationship. Among participants with high PBS use, the impact of descriptive drinking norms on drinking quantity disappeared. The indirect effect of descriptive drinking norms on alcohol consequences through drinking quantity was significant for individuals with low/moderate PBS use levels, but not for those with high PBS use. Our findings shed light on how descriptive drinking norms influence alcohol-related negative consequences, and suggest that promoting the utilization of PBS could be an effective approach to ameliorate the impact of peer influences on drinking behavior.

Furthering understanding of the scope and variation of alcohol and drug harms to others: Using qualitative discussion groups to inform survey development

Aims

Alcohol and drug use can have negative effects on family and friends of someone who uses these substances. To give voice to people with lived experience, we sought in-depth qualitative data from people who experienced such harms to others (HTO) to better understand the scope and variation of alcohol and drug HTO to inform future survey research in the United States (US).

Design

Five discussion groups with people from varied racial and ethnic groups.

Setting

Five US cities with different sociodemographic profiles and alcohol and drug use patterns.

Participants

Family members of individuals with substance use disorders (SUD).

Measures

Thematic analysis was used to identify themes and highlight harms that have not been well-represented in US general population surveys to date.

Findings

Discussion group participants described how alcohol and drug HTO can have long-lasting effects, raising questions about strategies to query and document harms occurring over the lifecourse. The emotional stress and burden of a close relationship with someone with SUD was a recurrent theme. Participants also noted how systems and policies may inadvertently intensify HTO through negative interactions with legal or social service entities. They also identified helpful community resources (including Al-Anon) for people impacted by someone else's substance use.

Conclusions

Qualitative data from people with relevant lived experience identified new areas for alcohol and other drug HTO research, including duration of harms across the lifespan, emotional and psychological impacts, and systems-level harms. Findings informed a redesign of our national survey instrument to efficiently capture the broad range of HTO.

Prevalence and Correlates of Alcohol and Drug Harms to Others: Findings From the 2020 U.S. National Alcohol Survey

OBJECTIVE

The purpose of this study was to measure the prevalence and overlap of secondhand harms from other people's use of alcohol, cannabis, opioids, or other drugs and examine sociodemographic and other correlates of these secondhand harms.

METHOD

This cross-sectional analysis used data from 7,799 respondents (51.6% female; 12.9% Black, 15.6% Hispanic/Latiné; mean age = 47.6 years) in the 2020 U.S. National Alcohol Survey. Secondhand harms included family/marriage difficulties, traffic accidents, vandalism, physical harm, and financial difficulties. Weighted prevalence estimates provided nationally representative estimates of these harms. Logistic regression assessed associations between individual characteristics and secondhand harms.

RESULTS

Lifetime prevalence of secondhand harms from alcohol, cannabis, opioids, or other drugs was 34.2%, 5.5%, 7.6%, and 8.3%, respectively. There was substantial overlap among lifetime harms: Almost 30% of those reporting secondhand alcohol harms also reported secondhand drug harms. Significant correlates of secondhand substance harms included female sex (alcohol, other drugs); White (alcohol, opioids), American Indian/Alaska Native (opioids), and Black (cannabis) race/ethnicity; and separated/divorced/widowed marital status (opioids). Those reporting a family history of alcohol problems had significantly higher odds of reporting secondhand harms across substance types. Individuals who reported frequent cannabis use had higher odds of reporting secondhand alcohol and opioid harms compared to those with no cannabis use (aOR = 1.55; aOR = 2.38) but lower odds of reporting secondhand cannabis harms (aOR = 0.51).

CONCLUSIONS

Although less prevalent than secondhand alcohol harms, 14% of participants reported secondhand harms from someone else's drug use and frequently experienced secondhand harms attributed to multiple substances. Population-focused interventions are needed to reduce the total burden of alcohol and other drug use.

Secondhand Harms From Cannabis Use: Findings From Washington State, United States

OBJECTIVE

There are few studies on harms attributed to others' cannabis use. We assessed individual- and contextual-level correlates of secondhand harms from cannabis use and considered whether cannabis legalization support, along with cannabis user status, predicted such harms.

METHOD

Data were from five repeated cross-sectional, state-representative telephone surveys of Washington State residents ages 18 and older, years 2014-2016. For four surveys, outcome variables were past-12-month reports of experiencing any of five harms (family, traffic-related, vandalism, physical, or financial), and in 2016 only, three harm types separately: (a) harassment, (b) safety-related (traffic, vandalism, physical), and (c) family or financial, attributed to another's cannabis use. All models included a three-category typology comprising participants' own cannabis use and whether they supported cannabis use legalization (user supporter, nonuser nonsupporter, nonuser supporter). We estimated logistic regression models for the full sample and by gender, adjusting for individual- and Census tract-level covariates.

RESULTS

Compared with non-cannabis users supporting legalization, nonusers who did not support legalization reported significantly greater odds of perceiving secondhand cannabis harms. Cannabis users supporting legalization did not differ from nonuser supporters. Predictors of reported harms also differed by gender. Whereas current drinkers had lower odds of reporting any harm from others' cannabis use overall, heavy-drinking women but not men reported greater odds of any cannabis secondhand harm.

CONCLUSIONS

Augmenting research on individual harms associated with cannabis use by including secondhand impacts such as social and family problems, along with safety risks, provides a more comprehensive picture of the effects of cannabis use.

Gender and sexual identity and harms from others' drinking among U.S. college students: Results from a multi-campus survey

BACKGROUND

College is a critical life stage for alcohol-related harms to others (AHTOs), gender, and sexual identity. We tested associations between inclusively-defined gender and sexual identities (separately) and AHTOs among college students.

METHODS

The Healthy Minds Study (n = 8,308) provided data about three AHTOs: (1) babysitting a drunk student, (2) alcohol-related unwanted sexual advance, and (3) alcohol-related sexual assault. Independent variables included gender and sexual identity.

RESULTS

One in four students (25.5%) reported babysitting, 6.2% reported unwanted advances, and 1.2% reported sexual assaults. Compared to cisgender males, cisgender females had higher odds of reporting babysitting (aOR = 1.36, p < 0.001) and unwanted advances (aOR = 2.59, p < 0.001); trans masculine students had higher odds of reporting sexual assaults (aOR = 4.49, p = 0.04).

CONCLUSIONS

AHTOs are prevalent on college campuses, and cisgender female and trans masculine students have higher odds of experiencing them. Alcohol interventions may protect cisgender female and gender minority students from the drinkers around them.

Harm from others' drinking among young adults in Taiwan: Predictors and deteriorating quality of life

INTRODUCTION

This study aimed to investigate the prevalence of different forms of harm from others' drinking (HFOD), predictors and the relationship with multi-dimensional quality of life among young adults in an emerging alcohol market in Asia-Taiwan.

METHODS

Data were extracted from a 2018 household survey with national representativeness on substance use experiences. The analytic sample comprised 4901 participants aged 18-34. Eight items were used to measure HFOD experiences. Five-dimensional quality of life was assessed by the EQ-5D-5L. Multivariable regressions with complex survey analyses were performed to estimate the prevalence and risk association.

RESULTS

Almost 4.2% of young adults experienced any form of HFOD; psychological harm occurred more prevalently than physical harm (3.7% and 1.5%, respectively). Those aged 25-29 and 30-34 had a two- to three-fold risk of HFOD compared with those aged 18-24. Both non-drunk drinking and drunk drinking were associated with an increased risk of psychological HFOD (adjusted odds ratio 2.36 and 5.89, respectively), whereas the risk of physical HFOD was related only to drunk drinking (adjusted odds ratio 7.8). Psychological HFOD victimisation emerged as the strongest predictor for deteriorated quality of life (adjusted b -0.14; 95% confidence interval -0.24, -0.04), especially in the dimensions of pain/discomfort and anxiety/depression. Among HFOD victims, only 33% sought help.

DISCUSSION AND CONCLUSIONS

The HFOD among young adults, commonly exhibited in psychological form, was linked with deteriorated quality of life; nonetheless, young HFOD victims are under-recognised. When devising interventions for alcohol harm, developmental perspectives should be integrated into policies implemented in healthcare and community settings.

Predictors of concerned others' mental health and quality of life over 12 months following adults' entry into treatment for an alcohol use disorder

INTRODUCTION

People in treatment for alcohol use disorders (AUDs) can negatively impact their Concerned Others (COs). This longitudinal study examined patient and CO characteristics associated with CO outcomes.

METHOD

Participants were 279 dyads of patients entering residential treatment and their CO. Outcomes were COs' mental health and quality of life. The study collected patient and CO predictors and CO outcomes at baseline and 3-, 6-, and 12-month follow-ups as part of a randomized controlled trial. In the first set of models, the analytic approach identified baseline patient predictors associated with COs' outcomes measured at baseline and follow-ups. In the second set of models, we examined whether those effects remained after adding baseline CO characteristics.

RESULTS

In the first set of models, COs of older age and whose patient reported less CO-patient relationship stress had better mental health. Also, married COs and those with higher income and whose patient reported no violence in the CO-patient relationship had better quality of life. In the second set of models, COs whose patient entered treatment due to criminal justice involvement, with more social support, less reported stigma, and less use of avoidance coping had better mental health. Also, married COs, those with higher income, and less reported discrimination stigma had better quality of life.

CONCLUSIONS

Understanding patient and CO characteristics that are associated with COs' outcomes may inform AUD treatment programs' efforts to help COs. Identifying modifiable determinants of CO outcomes is important to clinical practice regardless of whether the patient chooses to obtain treatment.

Web-Based Coping Skills Training and Coach Support for Women Living With a Partner With an Alcohol Use Disorder: Randomized Controlled Trial

BACKGROUND

Individuals living with a partner with an alcohol use disorder (AUD) can experience significant psychological distress and use health care more than those without a partner with an AUD. However, the prevailing treatment system's focus on the partner and personal barriers limit these individuals from getting help for themselves. Preliminary work on a self-directed, web-based coping skills training program, Stop Spinning My Wheels (SSMW), shows promise in broadening available treatments for this population. In this study, we conducted a robust evaluation of SSMW primary outcomes.

OBJECTIVE

The study aims to test whether women with a partner with an AUD assigned to SSMW experienced a greater reduction in negative affect (depression and anger) (1) than a usual web care (UWC) control and (2) with brief phone coach support (SSMW+coach) rather than without (SSMW only) and (3) whether baseline negative affect moderated treatment effects.

METHODS

Women (mean age 45.7, SD 10.8 years; Black: 17/456, 3.7%; White: 408/456, 89.5%) were randomized to SSMW only, SSMW+coach, or UWC. Depression (Beck Depression Inventory-II) and anger (State-Trait Anger Expression Inventory 2-State Anger) were assessed at baseline, 12-week posttest, and 6- and 12-month follow-ups.

RESULTS

Participants in all conditions decreased in depression from baseline to posttest and from baseline to follow-up; SSMW-only and SSMW+coach participants decreased in anger, but UWC participants did not. Compared to UWC participants, SSMW-only participants experienced greater anger reduction (P=.03), and SSMW+coach participants experienced a greater reduction in depression (P<.001) from baseline to posttest. However, from baseline to follow-up, only a greater, but not statistically significant (P=.052), reduction in anger occurred in SSMW+coach compared to UWC. Although the SSMW conditions did not differ from each other in negative affect outcomes (P=.06-.57), SSMW+coach had higher program engagement and satisfaction (all P<.004). Baseline negative affect did not moderate effects, although remission from baseline clinically relevant depressive symptoms (Beck Depression Inventory≥14) was higher in SSMW only (33/67, 49%; odds ratio 2.13, 95% CI 1.05-4.30; P=.03) and SSMW+coach (46/74, 62%; odds ratio 3.60, 95% CI 1.79-7.23; P<.001) than in UWC (21/67, 31%); remission rates did not differ between the SSMW conditions (P=.12).

CONCLUSIONS

The results partially supported the hypotheses. The SSMW conditions had earlier effects than UWC, but positive change in UWC mitigated the hypothesized long-term SSMW-UWC differences. The results highlight the importance of incorporating active controls in web-based clinical trials. Although SSMW+coach showed benefits over SSMW only on engagement and satisfaction measures and in the number needed to treat (5.6 for SSMW only; 3.2 for SSMW+coach), the SSMW conditions were comparable and superior to UWC on depressive symptom remission levels. Overall, SSMW with or without a coach can reduce clinically meaningful distress and add to available treatment options for this large, underserved group.

National and regional prevalence of interpersonal violence from others' alcohol use: a systematic review and modelling study

Background

While alcohol use is an established risk factor for interpersonal violence, the extent to which people are affected by interpersonal violence from others' drinking has not yet been quantified for different world regions. This modelling study aims to provide the first estimates of the national and regional prevalence of interpersonal violence from others' drinking.

Methods

An international systematic literature search (02/28/2023, Prospero: CRD42022337364) was conducted to identify general adult population studies assessing the prevalence of interpersonal violence from others' drinking with no restrictions to publication date or language. Reports that did not provide data on interpersonal violence from others' drinking (primary outcome), were no original research studies, or captured a selected group of people only, were excluded. Observed prevalence data were extracted and used to build fractional response regression models to predict past-year prevalence of emotional and physical violence from others' drinking in 2019. Random-effects meta-regression models were used to aggregate the observed prevalence of sexual and intimate partner violence. Study risk of bias (ROB) was assessed using a modified version of the Newcastle-Ottawa Scale.

Findings

Out of 13,835 identified reports, 50 were included covering just under 830,000 individuals (women: 347,112; men: 322,331; men/women combined: 160,057) from 61 countries. With an average prevalence of 16·8% (95% CI: 15·2-18·3%) and 28·3% (95% CI: 23·9-32·4%) in men and women combined in the GBD super regions High Income and Central Europe, Eastern Europe, & Central Asia, respectively, emotional violence was the most common form of interpersonal violence from others' drinking. Physical violence averaged around 3% (women) and 5% (men) in both regions. The pooled prevalence of sexual violence from others' drinking in men and women was 1·3% (95% CI: 0·5-3·3%, 95% PI: 0·1-16·9%) and 3·4% (95% CI: 1·4-8·3%, 95% PI: 0·2-35·3%), respectively, and ranged between 0·4% (95% CI: 0·1-1·6%, 95% PI: 0·0-7·3%) and 2·7% (95% CI: 1·1-6·3%, 95% PI: 0·2-30·0%) for different forms of intimate partner violence. ROB was moderate or critical for most reports; accounting for critical ROB did not substantially alter our results.

Interpretation

The share of the population experiencing harms from others' drinking is significant and should be an integral part of public health strategies.

How Do Bystanders Help in Drinking Situations: The Bystanders to Alcohol Risk Scale--Strategies

OBJECTIVE

Bystander intervention (BI) is a promising approach for promoting collective behavior change that has been applied to several domains, including sexual assault, bullying, and more recently, problematic alcohol use. Accurately measuring the strategies that bystanders use to reduce others' alcohol-related risk is an essential step toward improving bystanders' ability to reduce alcohol-related harm in their communities, but current measures of BI are not easily modifiable and applicable for alcohol-related BI. The current study aimed to develop a valid and reliable measure of the bystander construct most proximal to the reduction of risk: bystander strategies.

METHOD

Young adults (N = 1,011) who reported being around someone who showed signs of alcohol intoxication in the past 3 months were recruited via Qualtrics Panels to participate in an online survey; a subsample (n = 345) completed a 2-week follow-up. Psychometric evaluation included exploratory and confirmatory factor analyses, item response theory analyses, convergent validity, and test-retest reliability.

RESULTS

An initial set of 52 items was reduced to 17 items, representing two different factors. The first factor, Level 1, reflected strategies used during circumstances of acute risk. The second factor, Level 2, reflected strategies used to reduce risk for more longstanding problems with alcohol. Both factors demonstrated good model fit, strong internal consistency, evidence of convergent validity, and moderate test-retest reliability.

CONCLUSIONS

This novel measure can contribute to the production of knowledge about the use and efficacy of peer-focused strategies and the value of BI training for alcohol use.

Associations between alcohol use disorder polygenic score and remission in participants from high-risk families and the Indiana Biobank

BACKGROUND

In the United States, ~50% of individuals who meet criteria for alcohol use disorder (AUD) during their lifetimes do not remit. We previously reported that a polygenic score for AUD (PGSAUD ) was positively associated with AUD severity as measured by DSM-5 lifetime criterion count, and AUD severity was negatively associated with remission. Thus, we hypothesized that PGSAUD would be negatively associated with remission.

METHODS

Individuals of European (EA) and African ancestry (AA) from the Collaborative Study on the Genetics of Alcoholism (COGA) who met lifetime criteria for AUD, and two EA cohorts ascertained for studies of liver diseases and substance use disorders from the Indiana Biobank were included. In COGA, 12-month remission was defined as any period of ≥12 consecutive months without meeting AUD criteria except craving and was further categorized as abstinent and non-abstinent. In the Indiana Biobank, remission was defined based on ICD codes and could not be further distinguished as abstinent or non-abstinent. Sex and age were included as covariates. COGA analyses included additional adjustment for AUD severity, family history of remission, and AUD treatment history.

RESULTS

In COGA EA, PGSAUD was negatively associated with 12-month and non-abstinent remission (p ≤ 0.013, βs between -0.15 and -0.10) after adjusting for all covariates. In contrast to the COGA findings, PGSAUD was positively associated with remission (p = 0.004, β = 0.28) in the Indiana Biobank liver diseases cohort but not in the Indiana Biobank substance use disorder cohort (p = 0.17, β = 0.15).

CONCLUSIONS

PGSAUD was negatively associated with 12-month and non-abstinent remission in COGA EA, independent of behavioral measures of AUD severity and family history of remission. The discrepant results in COGA and the Indiana Biobank could reflect different ascertainment strategies: the Indiana Biobank participants were older and had higher rates of liver disease, suggesting that these individuals remitted due to alcohol-related health conditions that manifested in later life.

Satisfaction with a digital support tool targeting alcohol consumption: perspectives from participants in a randomized control trial

AIM

Intervention design may be improved through evaluating the feedback from those who have been exposed to such interventions. As such, here the perspectives of the intervention group from a recent randomized control trial investigating the effectiveness of a digital alcohol intervention, in terms of perceived suitability and usefulness of the support tool they engaged with, were investigated.

METHODS

Respondents (N=475; 45% of the intervention group) answered five quantitative questions addressing user experience, completed the 10-item System Useability Scale, and were offered the opportunity to write free-text feedback. Quantitative measures were analysed using ordinal and linear regression with baseline characteristics as predictors, and free-text responses were evaluated using content analysis.

RESULTS

Overall, respondents were positive towards the intervention in terms of it fitting their needs, the usefulness of the tools included, and the usefulness of text message content. The intervention was perceived as more helpful by respondents with lower total weekly alcohol consumption, higher self-reported confidence in their ability to reduce their drinking, and the perceived importance there of, at baseline. The free-text comments revealed the value of reminders as prompts to reflect on one's own drinking behaviour. Nonetheless, criticisms of the intervention were voiced, primarily highlighting the repetitive nature of the reminders and the lack of individuation in advice. Some also feltlike the intervention was impersonal and targeted only a specific drinking pattern.

CONCLUSIONS

Experiences of the intervention group in this trial were generally positive, though there may be demand for more individualised, targeted intervention design.

Alcohol protective behavioral strategies for young adults: a content analysis across drinking contexts and gender

Background: Protective behavioral strategies (PBS) are specific harm reduction behaviors which mitigate alcohol-related consequences among young adults. Prior work indicates PBS utilization varies according to drinking context and gender, suggesting a need for further research assessing whether young adults employ unidentified PBS according to such factors.Objectives: This study examined alcohol PBS young adults suggest using across drinking contexts and gender to inform alcohol-related harm reduction interventions.Methods: An online survey with 514 young adult heavy drinkers (n = 269 female, Mage = 22.36 years) assessed PBS use generally, and across 12 physical and social contexts. We utilized qualitative content analysis methods to code and derive themes from open-ended responses from a prompt asking participants to state additional PBS used per context. The frequency of each theme's appearance was calculated across the overall sample, by gender, and within each context.Results: PBS endorsement varied across context and gender within each theme. Young adults who reported PBS use most frequently endorsed utilizing strategies related to drink content (18.30%), social support (12.36%), and engaging in other activities (10.34%). Participants infrequently endorsed strategies related to awareness of time (0.23%), standards of behavior (0.78%) and avoiding environments (0.87%).Conclusions: Young adults endorse utilizing additional PBS in varying frequency according to drinking context and gender. Given PBS are often a key component of alcohol harm reduction interventions, monitoring trends in young adult PBS use is crucial to ensure continued relevance and efficacy of such interventions to minimize harms associated with young adult heavy alcohol use.

Alcohol's harm to others in 2021: Who bears the burden?

BACKGROUND AND AIMS

Alcohol's harm to others (AHTO) has become a key driver of national and international alcohol policy. This study aimed to produce a contemporary, comprehensive estimate of the correlates and harms from others' drinking in 2021 in Australia.

DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS

Across Australia, 2574 adults (1380 women; 1172 men) were sampled via two cross-sectional survey modes: a random-digit dial mobile phone sample of 1000 people and 1574 people from the Life in Australia™ panel survey. In 2021 participants were asked about harms they had experienced from the drinking of family, friends, co-workers and the public in the past year. Applying combined sample weights from each mode, bivariable and adjusted multivariable logistic regressions were used to analyse differences in rates of AHTO by participant gender, age, residence in rural or metropolitan regions, country of birth, education and employment.

FINDINGS

In 2021, 23.6% reported being negatively affected by strangers' drinking and 21.3% by the drinking of someone they knew, with 34.3% reporting being negatively affected a lot or a little by either; 42.4% of respondents reported specific harms from strangers' drinking. Thus, 48.1% of respondents reported any harm (negative effects or specific harms) from others' drinking. Women, younger people, Australian-born and heavier episodic drinkers reported significantly higher rates of AHTO compared with other respondents. Smaller percentages (7.5%) of participants reported being harmed substantially by others' drinking, including by people they knew (5.8%) or strangers (2.3%). Stratified analyses showed that heavier drinking, furloughed, younger men who were born overseas in English-speaking countries were affected by others' drinking, whereas women were affected regardless of these factors (apart from age).

CONCLUSIONS

More than one-third of Australian adults appear to have been negatively affected by others' drinking in 2021, with women, younger people and heavier drinkers at greater risk. Substantial harm appears to be more likely to arise from the drinking of people Australians know than from strangers' drinking.

Social disparities in alcohol's harm to others: evidence from 32 European countries

BACKGROUND

Alcohol use can cause harm not only to the person who consumes it but also to others. Prior research has found that these alcohol-attributable harms to others differ across socioeconomic groups, though several findings have been contradictory. The aim of this contribution was to study the role of individual-level and population-level income inequalities in alcohol's harm to others among women and men.

METHODS

Logistic regression analysis of cross-sectional survey data from 2021, covering 39,629 respondents from 32 European countries. Harms from others' drinking were defined as experiences of physical harm, involvement in a serious argument, or involvement in a traffic accident, due to another person's drinking, within the past year. We examined the association of individual-level income and country-specific income inequality (Gini index) with harms from a known person's or a stranger's drinking, adjusting for the respondent's age, daily drinking levels, and at least monthly risky single-occasion drinking.

RESULTS

At the individual level, people with lower incomes had 21% to 47% increased odds of reporting harms from a known person's drinking (women and men) or stranger's drinking (men only) than their same-gender counterparts in the highest income quintile. At the national level, countries with higher income inequality showed increased risks of harms from a known person's drinking among women (OR = 1.09, 95% confidence interval [CI]: 1.05 - 1.14), while among men the risk of harm from strangers' drinking decreased with higher income inequality (OR = 0.86, 95% CI: 0.81 - 0.92). These associations with income inequality were observed among respondents from all but the lowest income groups.

CONCLUSION

Alcohol can cause harm to others, with women and people with low incomes being disproportionally exposed to these harms. Alcohol control policies targeting high consumption levels, especially among men, as well as upstream policies to reduce inequalities, are needed to lower the health burden of alcohol beyond those who consume it.

Externalizing and internalizing problems as predictors of alcohol-related harm and binge drinking in early adolescence: The role of gender

BACKGROUND

Externalizing problems are commonly associated with alcohol outcomes in adolescence. Nevertheless, findings regarding internalizing problems are mixed, and fewer longitudinal studies have considered the both problems concomitantly and the role of gender. We examined the role of externalizing and internalizing problems in predicting adolescent alcohol-related harm and binge drinking, taking into account the gender differences. We also evaluated if externalizing problems could moderate the association between internalizing problems and alcohol outcomes.

METHOD

We used longitudinal data from 2368 8th grade students across 37 public schools in three Brazilian cities. Linear and logistic regressions were performed to analyze the association between alcohol outcomes and the independent variables (externalization and internalization scores, and sociodemographic variables) according to gender. We also tested the same model with an interaction term between externalizing*internalizing.

RESULTS

Our results suggest that externalizing problems predict adolescents' binge drinking in both genders; it also may predict adolescents' alcohol-related harms, but only in boys. Internalizing problems seem to be a gender-specific risk factor for binge drinking among girls. All findings are independent of comorbid problems and sociodemographic variables.

LIMITATION

The findings should be considered taking into account the short follow-up period from risk factors to the outcomes.

CONCLUSION

Our results highlight the contribution of internalizing and externalizing problems to the development of alcohol-related harm and binge drinking in early adolescence and the need for interventions to prevent early behavioral problems that consider the role played by gender.

Alcohol's harm to others in Japan: Different rates for different relationships to the drinker in a 2018 national survey

INTRODUCTION

No study in Japan has investigated alcohol's harm to others (AHTO). Therefore, this study aimed to reveal the situation of AHTO in Japan and examine the factors associated with it based on the relationship with the drinker.

METHODS

A cross-sectional population-based survey was performed in 2018 with 2121 men and 2507 women. Respondents were asked questions about factors such as verbal or physical aggression, being forced to drink alcohol, sexual harassment and their relationship with the drinker. Binomial logistic regression was performed to quantify the associations of AHTO with participants' socio-demographic status and drinking patterns.

RESULTS

The lifetime experience of AHTO was 24.7% for men and 19.3% for women. AHTO from the father and co-workers were the most common in and outside the home, respectively. The frequency of AHTO from the spouse or co-workers showed no significant difference for abstainers and drinkers. However, AHTO from the father was more commonly reported among drinkers and those with Alcohol Use Disorders Identification Test scores ≥8 points than abstainers. Of those who experienced AHTO, 24.5% of men and 27.6% of women, and 6.1% of men and 12.9% of women were profoundly affected by it in and outside the home, respectively.

DISCUSSION AND CONCLUSIONS

One in five Japanese residents experienced AHTO in their life, and the characteristics associated with AHTO differed according to the affected individual's relationship with the drinker. Continued monitoring of AHTO and measures aimed at reducing alcohol-related harm that include AHTO should be promoted.

Prevalence and self-rated health and depression of family members affected by addictive disorders: results of a nation-wide cross-sectional study

AIMS

To estimate the prevalence of family members affected by addictive disorders (FMA) with regard to various types of addictive disorders, and self-rated health and depression in the general population.

DESIGN

Cross-sectional general population survey.

SETTING

The German Health Update study (GEDA) 2014/2015, a nationally representative panel of German residents aged 15 years or older.

PARTICIPANTS

A total of 24 824 residents aged 15 years or older.

MEASUREMENTS

Participants were asked if they had a family member with current or past addictive disorder, the type of addiction and the relationship status. In addition, self-rated health and depression were assessed using standardized questionnaires.

FINDINGS

Of the respondents, 9.5% [95% confidence interval (CI) = 9.0-10.0] reported being affected by a current addictive disorder of a relative (cFMA), with a further 4.5% (95% CI = 4.2-4.9) reported having been affected by the addictive disorders of a relative in the past but not within the last 12 months (pFMA). Most FMAs reported having been affected by disorders due to alcohol, followed by cannabis and other drugs. Compared with life-time non-FMAs, FMAs reported significantly (P < 0.001) higher odds ratios for depression (cFM = 2.437; 95% CI = 2.082-2.853; pFMA = 1.850; 95% CI = 1.519-2.253) and ill-health (cFMA = 1.574; 95% CI = 1.374-1.805; pFMA = 1.297; 95% CI = 1.082-1.555).

CONCLUSIONS

In Germany, family members affected by addictive disorder are a substantial group within the general population. This group is characterized by ill-health and has not yet been adequately addressed by the addiction treatment system.

Effectiveness of a digital intervention versus alcohol information for online help-seekers in Sweden: a randomised controlled trial

BACKGROUND

The ubiquity of Internet connectivity, and widespread unmet needs, requires investigations of digital interventions for people seeking help with their drinking. The objective of this study was to test the effectiveness of a digital alcohol intervention compared to existing online resources for help seekers.

METHODS

This parallel randomised controlled trial included 2129 risky drinkers with access to a mobile phone and aged 18 years or older. Randomised sub-studies investigated consent procedures and control group design. Simple computerised randomisation was used. Participants were aware of allocation after randomisation; research personnel were not. The digital intervention was designed around weekly monitoring of alcohol consumption followed by feedback and tools for behaviour change. Primary outcomes were total weekly consumption (TWC) and frequency of heavy episodic drinking (HED), measured 2 and 4 months post-randomisation.

RESULTS

Between 25/04/2019 and 26/11/2020, 2129 participants were randomised (intervention: 1063, control: 1066). Negative binomial regression was used to contrast groups, with both Bayesian and maximum likelihood inference. The posterior median incidence rate ratio (IRR) of TWC was 0.89 (95% CI = 0.81;0.99, 98.2% probability of effect, P-value = 0.033) at 2 months among 1557 participants and 0.77 (95% CI = 0.69;0.86, > 99.9% probability of effect, P-value < 0.001) at 4 months among 1429 participants. For HED, the IRR was 0.83 (95% CI = 0.75;0.93, > 99.9% probability of effect, P-value = 0.0009) at 2 months among 1548 participants and 0.71 (95% CI = 0.63;0.79, probability of effect > 99.9%, P-value < 0.0001) at 4 months among 1424 participants. Analyses with imputed data were not markedly different.

CONCLUSIONS

A digital alcohol intervention produced self-reported behaviour change among online help seekers in the general population. The internal and external validity of this trial is strong, subject to carefully considered study limitations arguably inherent to trials of this nature. Limitations include higher than anticipated attrition to follow-up and lack of blinding.

TRIAL REGISTRATION

The trial was prospectively registered ( ISRCTN48317451 ).

Alcohol Protective Behavioral Strategies in Young Spanish Adults in the Community: A Prospective Study of Perceived Efficacy and Social Norms

BACKGROUND

Protective behavioral strategies (PBS) have been shown to be useful for reducing excessive alcohol use and alcohol-related problems. However, research on the explanatory factors of PBS is limited. This paper prospectively examines the contribution of perceived efficacy of PBS in reducing alcohol-related consequences and perceived descriptive norms of close peers´ PBS use in young adults. The mediating role of perceived efficacy of PBS between descriptive norms of PBS use and personal PBS use is also examined.

METHOD

Targeted sampling was used to recruit a community-based sample of 339 young Spanish adults aged 18-25 years, who completed baseline and two-month follow-up questionnaires. Three types of PBS (serious harm reduction-SHR, manner of drinking-MOD, and stopping/limiting drinking-SLD) were measured.

RESULTS

Both perceived efficacy and descriptive norms at baseline were positively associated with personal PBS use (SHR, MOD and SLD) at follow-up. A partial mediation effect of perceived efficacy between descriptive norms and personal PBS use was found for the three PBS subscales.

CONCLUSIONS

Our findings support the usefulness of correcting misperceptions of PBS use by peers in interventions aimed at reducing excessive drinking and alcohol-related consequences in young adults in the community. Moreover, PBS perceived efficacy should be included as a component of these interventions.

Work-Life Stress during the Coronavirus Pandemic among Latina Farmworkers in a Rural California Region

Objectives: To examine the type and severity of stressors experienced among Latina farmworkers during the COVID-19 pandemic. Methods: A survey containing the Migrant Farmworker Stress Inventory was administered to 77 female-identifying Latina farmworkers working in a US–Mexico border region. A sub-sample of five participants participated in key-informant interviews. Data collection occurred in Summer 2021. Results: Nearly 40% of Latina farmworkers reported high stress levels indicative of clinical mental health risks. Health and safety concerns and experienced stressors identified included visible substance abuse and poor bathroom conditions at the field site, language barriers, and balancing work and home life demands. Conclusions: Latina farmworkers have unique health and safety needs, and COVID-19 has contributed to the experienced stressors. Understanding the familial and working environment sources of stress specific to female agriculture workers is imperative to implementing culturally and gender-responsive strategies to better support the health and safety of farming populations in future pandemics.

Al-Anon Intensive Referral to facilitate concerned others' participation in Al-Anon Family Groups: a randomized controlled trial

AIMS

To test the effectiveness of an intervention, Al-Anon Intensive Referral (AIR), to facilitate participation in Al-Anon Family Groups (Al-Anon).

DESIGN, SETTING AND PARTICIPANTS

Multi-site, randomized controlled trial of AIR versus usual care (UC), with follow-up assessments at 3, 6 and 12 months. The 12-month follow-up rate was 74%. Residential alcohol use disorder (AUD) treatment programs in three US locations. Concerned others (COs) of patients in treatment for AUD. COs were mainly women (77%) who were patients' spouses (33%) or parents (25%).

INTERVENTION AND COMPARATOR

AIR (n = 128) consisted of four sessions over 3 months with an Al-Anon coach. UC (n = 151) was the treatment program's offer of educational sessions for COs.

MEASUREMENTS

Primary outcome: COs' self-reports of any Al-Anon attendance (yes or no) at 3 months.

SECONDARY OUTCOMES

number of Al-Anon meetings and the CO-patient relationship (stressors, resources). Potential predictors of outcomes examined in generalized linear mixed models were their baseline value, time, CO-patient relationship type (marital or non-marital), treatment program and condition.

FINDINGS

There was no effect of condition for the primary outcome (28% in AIR, 21% in UC; Bayes factor = 1.86). Relationship stressors at follow-ups were more severe for COs in a marital relationship with the patient than for COs in a non-marital relationship [β = 2.19, 95% confidence interval (CI) = 1.07, 3.32]. For CO-patient relationship resources at follow-ups, the main effect for condition was significant (β = 1.33, 95% CI = 0.04, 2.61). COs assigned to the AIR condition had more resources than COs who were in the UC condition.

CONCLUSIONS

Relative to usual care, Al-Anon Intensive Referral was not associated with increases in participation of concerned others in Al-Anon, but was associated with more resources in the concerned other-patient relationship.

Drinking and Neighborhood Contexts of Alcohol's Harms from Others

AIMS

Negative consequences of alcohol (or secondhand effects) extend beyond drinkers to affect other people, including both known others (friends, family members, spouses/partners) and strangers. Secondhand effects of alcohol manifest across various social environments, including the places where people drink and the neighborhoods where they live. These neighborhoods are characterized by different levels of alcohol availability and degrees of residential social cohesion. Hence, social environments may confer risk or protect from harms from others' drinking. The current study explores: (a) how drinking venues and neighborhood contexts relate to harms from other people's drinking (both known others and strangers), and (b) whether these associations vary by gender.

METHODS

Using pooled data from the National Alcohol Survey and National Alcohol's Harms to Others Survey (N = 5425), we regressed harms from various drinking others on social environment characteristics (drinking venues, alcohol availability and social cohesion) for the full sample and separately by gender. We used the false discovery rate method to adjust for multiple testing.

RESULTS

Overall, greater neighborhood social cohesion was associated with lower odds of harm from drinking others and, specifically, harm from drinking strangers. The effect of social cohesion was most pronounced for men.

CONCLUSIONS

Social cohesion was the most salient neighborhood factor associated with reduced alcohol-related harms from strangers. Directions for future research and policies to mitigate these harms are discussed.

Applying a 'harm to others' research framework to illicit drugs: political discourses and ambiguous policy implications

During the past decade, 'alcohol's harm to others' (AHTO) has emerged as an international approach to studying alcohol problems and informing policy. The AHTO approach seeks to increase political will for alcohol policy by mapping, measuring and often costing harms beyond the person who drinks (e.g. family members, co-workers). In this paper we consider the implications of a 'harm to others' approach for illicit drugs. We ask whether it could and should be used as a policy tool, given the high risks of further stigmatizing people who use drugs. We consider the ways in which the concept and measurement of 'harm to others' may be either productive or potentially harmful, depending on the extent to which the AHTO is replicated for illicit drugs. Shifting the language may assist: the term 'harm from others' appears to carry less risk of stigma. In addition, all harms inclusive of drug supply and drug consumption need to be included if a full picture of harms that accrue to other people from illicit drugs is to be achieved.

First- and second-hand alcohol-related harms among urban Chinese: A population-based study from Hong Kong

INTRODUCTION

Alcohol consumption has been steadily increasing in East Asia, however, there is comparatively little regional data of alcohol-related harms. This study examines the alcohol-related harms prevalence and risk factors in Hong Kong, a high population density city with limited alcohol regulation.

METHODS

A cross-sectional telephone survey was conducted in 2019 on Chinese adults aged 18-74 (n = 3200). Respondents were asked about various past-year first-hand drinking harms (after one's own drinking), second-hand harms (harms from other people's drinking) and views of neighbourhood alcohol outlet regulation.

RESULTS

Of drinkers, 21.1% reported first-hand alcohol harms, with physical/mental health harms (15.7%) most commonly reported. Younger-aged drinkers (adjusted odds ratios [AOR] 2.64, 95% confidence interval [CI] 1.63, 4.48) and heavy drinkers (AOR 2.34, 95% CI 1.55, 3.55) were more likely to report first-hand harms. Of the sample, 18.2% experienced past-year second-hand harms, with public harms (12.9%) most commonly reported. Young age (AOR 1.88, 95% CI 1.43, 2.49), higher education (AOR 1.44, 95% CI 1.13, 1.83), past-year binge drinking (AOR 4.29, 95% CI 3.04, 6.05) and communal living (AOR 2.04, 95% CI 1.13, 3.75) predicted greater likelihood of second-hand alcohol harms. Higher neighbourhood alcohol outlet density was not associated with any first-hand harms and only significantly predicted being inconvenienced by drinkers. Although victims of second-hand alcohol harms were more supportive of regulating outlet density, 93.3% of respondents were opposed to such policies.

DISCUSSION AND CONCLUSIONS

Although high levels of alcohol-related harms were not reported by Hong Kong adults, regulations should target young drinkers and binge drinkers who are most likely to experience drinking-related harms.

Interested constituents: identifying groups to mobilize in community organizing efforts to strengthen alcohol control policies

Background: Policy support research identifies demographic profiles of those who support policies, but community organizers aim to mobilize groups with an existing structure. Thus, identifying established groups that support alcohol policies may aid organizing efforts.Objective: This paper calculates prevalence and odds of policy support among three potential constituency groups (i.e., religious affiliation, persons harmed by others' drinking, and persons in recovery from alcohol) for three policies: alcohol tax increases, banning alcohol in corner stores, and universal coverage for alcohol treatment.Methods: Using the 2014-15 National Alcohol Survey (n = 3,444; 1,457 male, 1,987 female) and logistic regression, this study explores associations between constituency groups and policy support.Results: Support was higher for the individual-level strategy of alcohol treatment (80.8%) than raising taxes (27.5%) and banning sales in corner stores (52.2%). Support for taxes was higher among persons who valued religion highly (vs not; aOR = 1.46, p < .01), persons harmed by others' drinking (vs not; aOR = 1.71, p < .001), and persons in recovery (vs. not; aOR = 1.76, p = .02); Catholics had lower odds of support for taxes (vs no denomination; aOR = 0.63, p = .01). Persons who valued religion highly (aOR = 1.53, p < .001), Protestants (aOR = 1.63, p < .01), Catholics (aOR = 1.46, p = .03), and persons with other religious denominations (aOR = 2.17, p = .02) had higher odds of supporting bans in corner stores. Only those in recovery showed greater support for treatment (aOR = 3.20, p < .001).Conclusion: Overall, support was lower for population-wide approaches, but results revealed constituency groups that supported these policies. These groups may be allies to organizers who seek to reduce population-level alcohol consumption and harms.

Association between Exposure to Alcohol's Harm to Others and Health-Related Quality of Life in Korean Adults: A Nationwide Population-Based Study

This study aimed to investigate the association between exposure to alcohol's harm to others (AHTO) and health-related quality of life HRQoL using a nationally representative sample. Data from 2016-2018 of 17,346 South Korean individuals aged ≥19 years were obtained from the Korea National Health and Nutrition Examination Survey. HRQoL was evaluated using the European Quality of Life-5 Dimensions (EQ-5D) index. A significant positive association was found between exposure to AHTO and lower EQ-5D scores (p = 0.022). In the final model of multiple regression analysis, participants' HRQoL decreased by 0.932 points when exposed to AHTO (R² = 36.5%, p < 0.001). In addition, the exposure to AHTO group had significantly higher odds ratios (OR) for pain/discomfort (OR: 1.42, 95% CI: 1.15-1.75) and anxiety/depression (OR: 1.55, 95% CI: 1.68-2.80) compared to the non-AHTO group. Further studies are required for intervention when exposed to reduce the pain/discomfort and anxiety/depression in AHTO victims as well as to reduce the incidence of AHTO.

Cardiorespiratory Fitness Predicts Higher Inhibitory Control in Patients With Substance Use Disorder

Impaired inhibitory control has been shown in individuals with substance use disorder (SUD). Cardiorespiratory fitness has been described as a potential factor to improve inhibitory control; however, the benefits in individuals with SUD are unclear. The aim of this study was to investigate the relationship between cardiorespiratory fitness with general and drug-specific inhibitory control in individuals with SUD. Sixty-two male participants under treatment for SUD performed a general and drug-specific inhibitory control test (go/no-go) and a cardiorespiratory fitness test. Cardiorespiratory fitness, age, and years of drug use were inversely associated with reaction time for both general and drug-specific inhibitory control. In addition, the regression models showed that cardiorespiratory fitness predicts general and drug-specific inhibitory control adjusted for age and time of drug use. However, cardiorespiratory fitness predicts equally both general and drug-specific inhibitory control. These findings suggest that increasing cardiorespiratory fitness could provide benefits in the inhibitory function of individuals with SUD.

Are Countries' Drink-Driving Policies Associated With Harms Involving Another Driver's Impairment?

INTRODUCTION

International drink-driving policy research generally focuses on aggregate outcomes (e.g., rates of crashes, fatalities) without emphasizing secondhand alcohol-related vehicular harms. In contrast, we investigate associations between drink-driving policies and harms involving another driver's impairment.

METHODS

Alcohol's harms to others (AHTO) survey data from 12 countries (analytic N = 29,616) were linked to national alcohol policy data from the World Health Organization. We examined separately associations of two 12-month driving-related AHTOs (passenger with an impaired driver; vehicular crash involving someone else's drink driving) with 3 national drinking-driving policies-legal blood alcohol concentration (BAC) limits, use of random breath testing, use of sobriety checkpoints, and comprehensive penalties for drink-driving (community service, detention, fines, ignition interlocks, license suspension/revocation, mandatory alcohol treatment, vehicle impoundment, and penalty point system), plus 2 alcohol tax variables (having excise taxes and value-added tax [VAT] rate). Multilevel logistic regression addressed clustering of individuals within countries and subnational regions, while adjusting for individuals' gender, age, marital status, risky drinking, and regional drinking culture (% male risky drinkers in sub-national region).

RESULTS

Controlling for national-, regional-, and individual-level covariates, comprehensive penalties were significantly and negatively associated with both outcomes; other vehicular policy variables were not significantly associated with either outcome. A society's VAT rate was negatively associated with riding with a drunk driver. Regional male drinking culture was positively associated with riding with an impaired driver, but was not significantly associated with being in a vehicular crash due to someone else's drinking. In both models, being male, being younger, and engaging in risky drinking oneself each were positively associated with vehicular harms due to someone else's drinking.

CONCLUSIONS

Although results are associational and not causal, comprehensive penalties may be promising policies for mitigating driving-related harms due to another drinker. Higher VAT rate might reduce riding with a drunk driver.

Intersection of familial risk and environmental social control on high-risk drinking and alcohol dependence in a US national sample of adults

BACKGROUND

Effects of a family history of alcoholism may be moderated by area-level social control factors. We examine whether increased neighborhood alcohol availability (low social control environment) or increased presence of religious adherents in the county (high social control environment) interact with family history in relation to alcohol outcomes.

METHODS

Weighted data from 12,686 adult drinkers (51% male; mean age 44; 80% White, 9% Black, 11% Hispanic) in three US National Alcohol Surveys were linked with data on area-level off-premise alcohol availability and adherence to religions with strong prohibitions against drinking. Family history density had four levels (family history negative, extended family only, first-degree relative(s) only, high family density). Dichotomous outcomes were past-year high-risk drinking and alcohol dependence. Logistic regression models with interaction terms assessed whether associations of family history with alcohol outcomes differed significantly by area-level social control. Stratified models assessed differences by sex and by race/ethnicity.

RESULTS

In the full sample, effects of first-degree relatives and high family density on high-risk drinking strengthened as alcohol availability increased. This was replicated in the subsample of women and suggested in relation to dependence among men and Black drinkers. For White drinkers, higher religious social control reduced effects of first-degree relatives on high-risk drinking.

CONCLUSIONS

Low social control-in particular, greater density of off-premise alcohol outlets-appears to exacerbate effects of a family history of alcoholism on high-risk drinking. Policy makers should consider differential benefits of decreasing alcohol availability for people from high-risk families to reduce high-risk drinking and alcohol problems.

The Association Between Family Violence, Depression and Anxiety Among Women Whose Partners Have Been Treated for Alcohol Dependence

The negative effects of men's excessive alcohol consumption on family members are well known. However, less is known about how men's alcohol dependence is associated with the mental health of their female spouses residing with them. Therefore, the aim of this study was to investigate the prevalence and factors associated with depression, anxiety, and intimate partner violence against women (IPVAW) whose male spouses are undergoing treatment for alcohol dependence. We hypothesize that men with alcohol dependency, who are also violent, present a serious threat to women's mental health. We conducted a cross-sectional study among 104 women whose male partners had been admitted for inpatient treatment for alcohol dependence. Women's depression was measured by the Beck Depression Inventory (BDI-II); anxiety was measured by the Beck Anxiety Inventory (BAI), and exposure to physical and sexual IPVAW was measured by the Conflict Tactics Scale (CTS-2). Multinomial logistic regression analyses were conducted in order to analyze factors associated with depression and anxiety. The prevalence of moderate/severe depression and anxiety among the women was 34.6% and 25.2%, respectively, while almost half (48.1%) experienced IPV during the past 12 months. After adjustments for age, exposure to IPV increased the chances of experiencing moderate/severe depression by 37.5 times (95% CI 7.91-177.76), and 8.15 times for moderate/severe anxiety (95% CI 2.45-27.14). The mental health of women whose partners have alcohol dependence is significantly threatened and should be considered, especially when it is associated with exposure to spousal violence.

Harm from Others' Drinking Among Sexual Minority Adults in the United States

Purpose: Due to discrimination and stigma, sexual minority adults may be more likely than their heterosexual counterparts to experience harms from other people's drinking. We compared prevalence of second-hand alcohol harms for sexual minority and heterosexual adults in the United States. Methods: Data from the 2014-15 U.S. National Alcohol Survey (n = 5516; 10.2% sexual minority adults) were analyzed using logistic regression with survey weights to account for sampling and nonresponse. Multivariable models included simple main effects of sexual identity on the past-year harm outcomes, as well as interactions of drinker status with sexual identity. Results: In bivariate results stratified by sex, bisexual women were significantly more likely than heterosexual women to report all five types of harms. Lesbian respondents had greater odds relative to heterosexual women of reporting harm by a friend/coworker and assault or physical harm by a drinker. Bisexual identity among men was associated with greater odds of reporting assault/physical harm relative to heterosexual men in bivariate models. In adjusted models, differences by sexual identity were substantially reduced, with significance remaining only for friend/coworker-perpetrated harms and assault/physical harm among lesbian respondents compared with heterosexual women. For assault/physical harm, an interaction of sexual identity with the respondent's own drinking showed that the increased odds of harm associated with heavy drinking was even greater among sexual minority respondents (both bisexual and lesbian/gay respondents) than among heterosexual respondents. Conclusion: These findings underscore the importance of preventive interventions that consider disparities in risk for alcohol-related harms, particularly interpersonal violence, among sexual minority adults in the United States.

Severe harm from others' drinking: A population-based study on sex differences and the role of one's own drinking habits

Introduction and Aims

Despite the fact that many studies have focused on harm from others' drinking, there is a lack of knowledge regarding severe forms of these harms. This study aimed to assess sex differences in the prevalence of severe harm from others' drinking and sex‐specific associations with one's own drinking.

Design and Methods

The data originated from a Swedish cross‐sectional population survey (n = 15 576). Adjusted odds ratios of self‐reported experiences of severe harm (harmed ‘a lot’) from others' drinking were calculated using logistic regression models. Additive interactions were used to determine sex‐specific associations between own drinking and harm.

Results

The past‐year prevalence of severe harm from known and unknown drinkers was higher among women (4.9% and 1.8%, respectively) than men (1.9% and 1.2%, respectively). Alcohol dependence predicted such harm for both sexes. No association with severe harm from known drinkers was found for male drinkers and binge drinkers, whereas female drinkers and binge drinkers reported more experiences of such harm. These differences indicated a supper‐additive interaction (RERI: 0.92–1.47) and signs of having alcohol dependence among women indicated an even higher interaction (RERI: 5.37).

Discussion and Conclusions

Women suffer more frequently from severe harm from others' drinking. Men and women report different experiences of severe harm from known people's drinking conditioning on their drinking behaviour. Sex‐specific longitudinal studies are warranted to examine the relation between different behaviours and these harms. Whether these findings hold in settings with different drinking cultures and social norms should be explored.

Association between one's own consumption and harm from others' drinking: Does education play a role?

Introduction: We examined (a) whether risky drinking behaviour is related to experienced harm from others' drinking (EHFOD) and (b) whether any found relationship is modified by educational level, such that those of lower socio-economic status (SES) experience more harm even when adjusted for drinking behaviour. Method: Data from the Danish national alcohol and drug survey of 2011 (N=5133) were linked with registry data from Statistics Denmark. Eight EHFOD indicators were grouped into nuisance, harassment or harm/damage categories. Indicators for mean alcohol consumption, Alcohol Use Disorder Identification Test (AUDIT) and binge drinking were examined in relation to respondents' EHFOD with multiple logistic regression, stratified by sex and education (proxy for SES). Results: One-year prevalence of EHFOD was 50%. We found a positive and significant relationship between own alcohol consumption and EHFOD categories of harassment as well as harm/damage. Effect modification of education was significant for harassment. Among men, odds ratios for the association between risky drinking behaviour and harassment were 5.50 (95% confidence interval (CI) 3.49-8.65) in the low educational group versus 1.42 (95% CI 0.98-2.07) in the high educational group. Conclusions: Our study confirmed an overall positive relationship between EHFOD and drinking behaviour, but it varied by type of EHFOD. Furthermore, education modified this effect for harassment, suggesting evidence of the alcohol harm paradox with respect to EHFOD. More research is necessary to understand better how drinking patterns diverge between low and high educational groups as well as sex, and how this differentially affects risk for alcohol-related harms, including EHFOD.

Gender differences in social harms from drinking among young Australians: findings from the Mater University Study of Pregnancy and its Outcomes

Background: Despite the growing interest in investigating social harms from drinking, little is known about drinkers' reports of these harms and their gender differences among Australian young adults at age 30. We aimed to examine gender differences of social harms from drinking as reported by drinkers.Methods: 2,200 young adults at age 30 with complete data on social harms from drinking were drawn from the 30-year follow-up of the Mater-University of Queensland Study of Pregnancy. Measures included percentages of 11 past-year drinkers' self-reported social harms stratified by gender. Logistic regression was used to examine associations between gender and each social harm, accounting for relevant confounding.Results: More than one in five young adults (22%) reported at least one social harm in the past year. Among binge drinkers, 44% reported at least one social harm. After adjustments for social roles and binge drinking, we found no gender differences on several self-reported social harms: friendship problems, people criticizing drinking, non-marital family problems, employment problems, and alcohol-fuelled fights. However, men were more likely to report spousal threats to leave, drink-driving legal problems and financial problems.Conclusions: Our findings demonstrate that young adults are still vulnerable to risky drinking at age 30 and the social harm resulting from drinking. Thus, alcohol prevention campaigns should target this age group and include women in their focus. Strategies aiming to reduce alcohol-related harms, such as screening in clinical settings for risky drinking and alcohol-related harms, followed by motivational behavior interventions, could be beneficial among these vulnerable groups.

Association between state-level alcohol availability and taxation policies on the prevalence of alcohol-related harms to persons other than the drinker in the USA, 2000-2015

INTRODUCTION AND AIMS

Alcohol-related harms to others (AHTO) are consequences of alcohol use borne by persons other than the drinker. This study assessed whether the odds of experiencing AHTO are associated with alcohol availability and taxation policies.

DESIGN AND METHODS

This study pooled data from four waves of the National Alcohol Survey (n = 20656 adults). We measured past-year AHTO exposure using three binary variables: physical (pushed/hit/assaulted or property damage by someone who had been drinking), family or financial (family/marital problems or financial harms by someone who had been drinking) and driving AHTO (riding in a vehicle with a drink-driver or being in a drink-driving crash). Policies included bar and off-premise alcohol outlet density (separately), alcohol retail hours, beer and spirits taxes (separately) and monopoly on retail/wholesale alcohol purchases.

RESULTS

Monopolies were associated with 41.2% lower odds of physical harms [adjusted odds ratio (aOR) = 0.59, 95% confidence interval (CI) 0.45, 0.77, q < 0.001 correcting for multiple analyses], and a 10% increase in bar density was associated with a 1.2% increase in odds of driving-related harms ( e ^{ln(1.1) * β} =1.01, 95% CI 1.00, 1.02, q = 0.03). Among men, beer taxes were associated with lower odds of physical harms ( e^{ln(1.1) * β} =0.93, 95% CI 0.88, 0.98 q = 0.03) and monopolies were associated with lower odds of physical (aOR = 0.45, 95% CI 0.35, 0.59, q < 0.001) and driving harms (aOR = 0.66, 95% CI 1.00, 1.02, q = 0.03).

DISCUSSION AND CONCLUSIONS

Monopolies, taxes and outlet density are associated with odds of some AHTO. Future longitudinal research should test whether physical availability and taxation policies may be protective for bystanders as well as drinkers.

New approach for the measurement of long-term alcohol consumption trends: Application of wastewater-based epidemiology in an Australian regional city

BACKGROUND

Wastewater-based epidemiology (WBE) provides complementary information to traditional self-report methods for estimating substance use within a population. WBE was applied to estimate the consumption of alcohol in an Australian rural city (population estimated 100,000) over 6 years.

METHODS

A total of 352 wastewater samples were analysed from a wastewater treatment plant located in South-East Queensland, Australia, from 2012 to 2017. The concentration of an alcohol biomarker, ethyl sulphate, was quantified by liquid chromatography tandem mass spectrometry and used to estimate per-capita consumption. The WBE results were compared with alcohol consumption estimates based on national taxation data and self-reported national survey data in Australia.

RESULTS

Average daily alcohol consumption estimated by WBE was between 19 and 30 mL/person/day for the population aged 15 years and older during the six-year period. Alcohol consumption decreased 4 % per annum on average over the study period. Our data showed higher rates of consumption on weekends and public holidays when compared to consumption between Monday and Thursday. The comparative trend of WBE data was consistent with the national alcohol survey and taxation statistics on alcoholic beverages over the same period.

CONCLUSIONS

A clear decline in alcohol consumption in the catchment was observed during the sampling period, which reflected similar changes in consumption from taxation statistics and self-report survey data. Expected variations in weekly consumption and public holidays were also identified. This study demonstrates the potential of WBE for long-term monitoring of alcohol consumption in evaluating the effectiveness of local and national alcohol policies and prevention programs.

Cross-National Comparisons and Correlates of Harms From the Drinking of People With Whom You Work

BACKGROUND

While research in high-income countries (HICs) has established high costs associated with alcohol's harm to others (AHTO) in the workplace, scant attention has been paid to AHTO in the workplace in lower- or middle-income countries (LMICs).

AIM

To compare estimates and predictors of alcohol's impacts upon coworkers among workers in 12 countries.

METHODS

Cross-sectional surveys from 9,693 men and 8,606 women employed in Switzerland, Australia, the United States, Ireland, New Zealand, Chile, Nigeria, Lao PDR, Thailand, Vietnam, India, and Sri Lanka. Five questions were asked about harms in the past year because of coworkers' drinking: Had they (i) covered for another worker; (ii) worked extra hours; (iii) been involved in an accident or close call; or had their (iv) own productivity been reduced; or (v) ability to do their job been affected? Logistic regression and meta-analyses were estimated with 1 or more harms (vs. none) as the dependent variable, adjusting for age, sex, rurality of location, and the respondent worker's own drinking.

RESULTS

Between 1% (New Zealand) and 16% (Thailand) of workers reported that they had been adversely affected by a coworker's drinking in the previous year (with most countries in the 6 to 13% range). Smaller percentages (<1% to 12%) reported being in an accident or close call due to others' drinking. Employed men were more likely to report harm from coworkers' drinking than employed women in all countries apart from the United States, New Zealand, and Vietnam, and own drinking pattern was associated with increased harm in 5 countries. Harms were distributed fairly equally across age and geographic regions. Harm from coworkers' drinking was less prevalent among men in HICs compared with LMICs.

CONCLUSIONS

Workforce impairment because of drinking extends beyond the drinker in a range of countries and impacts productivity and economic development, particularly affecting men in LMICs.

Complexities of Young Driver Injury and Fatal Motor Vehicle Crashes

We offer a perspective on the literature discussing the importance of driving for youth, the complexities of learning to drive, and the risks of driving which lead to motor vehicle crashes (MVCs). Specifically, we discuss important underlying reasons why some adolescents and young adults may be more susceptible to engaging in driving behaviors which result in fatal MVCs; the leading cause of death among 15 to 20 y/o. Some of the factors known to lead to crash fatalities span the domains of cognitive development, distraction, alcohol/drug use, psychosocial development and peer influence, and young driver inexperience. While advancements in driver training, traffic safety legislation, vehicle safety engineering, and emergency/trauma care have helped reduce the prevalence of crashes, we suggest that natural brain maturation which occurs during adolescence and young adulthood may hold unique susceptibilities for young driver crashes. As such, we discuss the importance in using a multidisciplinary research approach, and specifically neuroscience methods, to develop a more compressive understanding of crash risk factors among young drivers. By using a multidisciplinary approach when studying young drivers, we can advance the injury and prevention science as well as inform relevant policies, innovative technologies, comprehensive training and intervention programs which will develop safer young drivers sooner.

Gender Equality, Drinking Cultures and Second-Hand Harms from Alcohol in the 50 US States

BACKGROUND

Gender inequality and cultures of binge drinking may increase the risk of second-hand harms from alcohol.

METHODS

Using the 2014-2015 National Alcohol Survey and 2015 National Alcohol's Harm to Others Survey (N = 7792), we examine associations of state-level gender equality measures (contraceptive access, abortion rights, women's economic equality) and binge drinking cultures (rates of men's and women's binge drinking) with individual-level indicators of second-hand harms by drinking strangers and partners/spouses.

RESULTS

In main effects models, only male binge drinking was associated with greater odds of harms from drinking strangers. There were significant interactions of gender equality with male binge drinking: High male binge drinking rates were more strongly associated with stranger-perpetrated harms in states low on contraceptive access or abortion rights compared to states high on these measures. Conversely, male binge drinking was more strongly associated with spouse/partner-perpetrated second-hand harms in states with more economic equality, compared to states lower on this measure.

CONCLUSIONS

Detrimental effects of high male binge drinking rates may be modified by gender equality. Targeted interventions may reduce alcohol-related harms experienced by women in states with high rates of male binge drinking. Restrictions in access to contraception and abortion may exacerbate harms due to men's drinking.

De-mythologizing and re-branding of kava as the new ‘world drug’ of choice

What seemed impossible 50 years ago is today becoming a reality as ‘soft drugs’ such as cannabis are being decriminalized and accepted for their calming effects as well as their legitimate medicinal properties. Several countries have now made the possession of cannabis legal, with others considering this, while the coffee shops in the Netherlands have been supplying cannabis in different forms for many years. It is now the turn of kava to be re-evaluated, to see whether there are properties in this plant that might be readily substituted for more conventional and harmful drugs, for instance tobacco and alcohol. However, as highlighted by Norton and Ruze (1994), kava like cannabis, has an enduring reputation that still makes it difficult for many to accept. Kava has been mythologized as an illicit alcohol, highly addictive, and causing physical harm. When examining the history of kava use in traditional contexts and considering the evidence now available, it is possible to demythologize this characterization. Looking at the potential benefits, it is time to re-brand kava, not only on the grounds as a relaxant, but in possessing life enhancing medicinal properties and as an alternative to alcohol, understanding that will be beneficial to policy makers, doctors and pharmacists.
