The hidden impact of alcohol on young victims: an analysis of alcohol-related police offences resulting in hospitalisation.

BACKGROUND: Alcohol-related harm (ARH) is a significant public health concern affecting young individuals, particularly those involved in alcohol-related police incidents resulting in hospitalisation. However, the impact of alcohol on young victims remains under researched. This study aimed to identify the characteristics of offenders and victims involved in these incidents, analyse the types of offences, and understand the under-ascertainment of ARH in hospital records. METHODS: A retrospective longitudinal study of 12-24-year-olds born between 1980 and 2005 was conducted using linked data from hospital admissions, emergency department presentations, and police incident records. Alcohol-related incidents were identified based on the attending officers' opinions in the Western Australia Police's Incident Management System (IMS). Logistic and log-binomial regression were utilised to analyse the factors associated with victimisation and under-ascertainment of ARH. RESULTS: Our study included 22,747 individuals (11,433 victims and 11,314 offenders) involved in alcohol-related police incidents, with a small majority of victims being female (53%, n = 6,074) and a large majority of offenders being male (84.3%, n = 9,532). Most victims did not receive a diagnosis of ARH (71%, n = 760). Women were 10 times more likely to have been a victim in ARH police incidents and 2 times more likely to have an undiagnosed alcohol-related hospital admission than men. Victims and offenders predominantly came from disadvantaged areas and major cities. Aboriginal individuals were overrepresented as both offenders and victims. A significant proportion of individuals experienced emergency department presentations or hospital admissions, with head injuries being the most common. Assault causing bodily harm was the most prevalent offence resulting in hospitalisation (66%, n = 2,018). CONCLUSIONS: There is a noteworthy disparity between the quantity of hospital admissions attributed to alcohol-related incidents and the number of cases that are formally classified as ARH in the hospital system. This disparity highlights a more profound issue of substantial under-ascertainment or inadequate identification of ARH than previously acknowledged. Our findings justify the prioritisation of prevention strategies, beyond improvement in the documentation of alcohol-related hospitalisation. Considering the scale of the problem, and the underestimation of the burden of alcohol-related hospitalisation, a proportional increase in investment is necessary to achieve population-level reductions in ARH.

Assessing the utility of night-time presentations as a proxy for alcohol-related harm among young emergency department trauma patients.

OBJECTIVE: To assess the usefulness of night-time presentations to measure alcohol-related harm (ARH) in young trauma patients, aged 12-24 years, attending Western Australian EDs. METHODS: A retrospective longitudinal study examined alcohol-related ED presentations in Western Australia (WA; 2002-2016) among 12- to 24-year-olds. Data from the Emergency Department Data Collection, WA State Trauma Registry Database and Hospital Morbidity Data Collection were used to identify ARH through specific codes and text searches. These were compared to ARH estimates based on presentation time. Statistical analysis involved sensitivity and specificity calculations and Cox proportional hazards modelling. RESULTS: We identified 2644 (17.8%) night-time presentations as a proxy measure of ARH among the 14 887 presentations of patients aged 12-24 years. This closely matched the 3064 (20.6%) identified as ARH through coding methods. The highest risk for an ARH presentation occurred during the night hours between 00.00 and 04.59 hours. During these hours, the risk was 4.4-5.1 times higher compared to presentations at midday (between 12.00 and 12.59 hours). However, when looking at individual patients, we observed that night-time presentations were not a strong predictor of ARH (sensitivity: 0.39; positive predictive value: 0.46). CONCLUSIONS: Implementing targeted interventions during night hours could be beneficial in addressing ARH presentations. However, relying solely on the time of presentation as a proxy for ARH is unlikely to effectively identify ARH in young individuals. Instead, the present study emphasises the importance of implementing mandatory data collection strategies in EDs to ensure accurate measurement of ARH cases.

How effective are health messages/warnings in improving knowledge and awareness of alcohol-related harm? The Slovenian case on using a mobile app.

BACKGROUND: Consumers generally lack access to information on alcoholic beverages, in spite of it being readily available for food and non-alcoholic beverages. Given the rights of consumers, and as with other products harmful to the population, there have been increasing calls for health warnings to be placed on alcoholic beverages, similar to those implemented on tobacco products. The aim of our research was to assess whether knowledge and awareness of the risks and harms associated with alcohol can be improved with a mobile app. METHODS: Intervention was conducted using VKJ mobile app, which enables users to scan the barcode of an alcoholic beverage and receive feedback on its labelled alcohol content and estimated energy value. At each search, eleven different health messages/warnings about the risks and harms of alcohol are also displayed randomly, rotating on the screen. A survey was conducted before and after the intervention, to assess the knowledge and awareness of the risks and harms associated with drinking alcohol. RESULTS: Significant differences were found for eight of the twelve tested statements. The improvement was seen to a greater extent in the group of high-risk drinkers. The results also showed that the vast majority of participants (78%) who were exposed to the health messages supported mandatory labelling of alcoholic beverages with information on ingredient listing and energy value, and 72% would like to have health warnings on alcohol products. CONCLUSIONS: The use of a mobile app can be an option to improve knowledge and raise awareness of the risks and harms related to alcohol.

"It's like a safety net for when things go wrong": key stakeholder and program user perspectives on a peer-led safe space program in Sydney, Australia.

BACKGROUND: Safe Spaces are a harm reduction approach commonly utilised in nightlife and festival settings to address alcohol and other drug-related harms. Despite increasing use, there has been little independent evaluation of safe space programs. This study aimed to explore (1) program user satisfaction with and use of a safe space program implemented in Sydney, Australia (The Take Kare Safe Space (TKSS)), and (2) the strengths and weaknesses of TKSS from the perspective of key stakeholders. METHODS: Semi-structured, in-depth, interviews lasting between 30 min to 1 h were conducted with 38 key program stakeholders, including staff from police (n = 4), ambulance (n = 4), a local hospital accident and emergency room (n = 4), local council (n = 2), city 'rangers' (n = 2), the TKSS program (n = 4), licensed venues and other nightlife service providers (n = 4), and program users (n = 14). Purposive sampling was used to identify key stakeholders to participate in interviews. RESULTS: Stakeholders stated that the TKSS program had a number of core benefits, including that it filled a service gap in nightlife settings; improved the efficiency and effectiveness of emergency services and other stakeholders operating in nightlife precincts; provided welfare services through proactive and non-judgmental interventions; and facilitated a means to de-escalate conflict without engaging police. Perceived weaknesses of the program included a lack of public awareness about the program; staff and volunteer levels; and misunderstandings regarding the scope and function of the TKSS program by some stakeholders. CONCLUSION: This study demonstrates the complex relationships that exist around the delivery of harm reduction in nightlife settings. In particular, it highlights the relative lack of servicing of public nightlife settings and the value of safe spaces/peer-to-peer safety ambassador programs in linking up care and filling this service gap. Further, it documents the extended benefit across key stakeholder groups of delivering proactive and non-judgemental harm reduction services and, in doing so, provides critical evidence around their efficacy in reducing AOD-related harms in the night-time economy.

"When a man drinks alcohol it's cool but when a woman drinks she is a hoe": A Qualitative Exploration of Alcohol, Gender, Stigma, and Sexual Assault in Moshi, Tanzania.

Background: Alcohol's ever-increasing global use poses a distinct threat to human well-being, with intake and associated burdens rising especially quickly in low- and middle-income countries like Tanzania. Prior research has shown alcohol use and related consequences differ by gender in Moshi, Tanzania, with important implications for both clinical care and future alcohol-reduction interventions. This study builds upon this knowledge by providing a deeper understanding of how gender differences affect alcohol-related stigma and sexual assault among Emergency Department (ED) and Reproductive Health Center (RHC) patients at Kilimanjaro Christian Medical Center (KCMC) in Moshi. Methods: In-depth interviews (IDIs) were conducted among ED and RHC KCMC patients (n = 19) selected for participation via purposive sampling. A mix of inductive and deductive coding schemes was used to identify themes and subthemes. All data were analyzed through a grounded theory approach. Results: Gender roles that linked men with financial responsibilities and women with child caretaking led to different expectations on alcohol intake, with alcohol use normalized for men but vilified for women. Women who drank, for example, were deemed poor mothers and undesirable spouses. Patients likewise emphasized that both alcohol-related stigma and sexual violence disproportionately impacted women, the latter fueled through alcohol use, with serious and lasting acts of discrimination and isolation from community members seen among women alcohol users but not for men. Conclusion: Women alcohol users in Moshi are subject to severe social consequences, facing disproportionate stigma and sexual violence as compared to men. Alcohol-related treatment for women should be mindful of the disproportionate burdens present in this context and incorporate strategies to address and/or mitigate these harms in subsequent care and interventions.

Socioeconomic inequalities in alcohol-related harm in adolescents: a prospective cohort study of 68,299 Danish 15-19-year-olds.

Background: Evidence shows that similar levels of alcohol consumption lead to greater harm in adults with low socioeconomic position (SEP) compared to high SEP. We investigated if SEP is associated with alcohol-related hospital contacts in adolescents, and whether differences in risk can be explained by differences in levels of alcohol consumption, drinking pattern, and substance use. Methods: This is a prospective cohort study of 68,299 participants aged 15-19 years old from the Danish National Youth Cohort 2014. SEP was operationalised as parent educational level, family income and perceived financial strain in the family. Data were linked to national registers and participants were followed up for five years from 2014 to 2019. Outcomes were hospital contacts due to alcohol. Multilevel Poisson regression was used to estimate incidence rates (IR) and incidence rate ratios (IRR). Findings: During 280,010 person years of follow-up, 872 participants had an alcohol-attributable hospital contact; intoxications (n = 778, 89%) were the most common diagnosis. Low as compared to high SEP was associated with higher IRR of alcohol-attributable hospital contacts for all three SEP measures. The adjusted IRR of harm was 1.73 (95% CI: 1.29-2.33) for elementary school as the highest parent education compared to longer parent education and 1.57 (95% CI: 1.30-1.89) for family financial strain compared to those without financial strain. Adjustment for weekly alcohol intake, drinking pattern and substance use did not substantially change results. Cubic spline analysis of the association between family income and alcohol-attributable hospital contacts revealed a dose-response relationship with decreasing risk of alcohol-related harm with higher income. Interpretation: Our findings suggested that alcohol-related harm is more common in socioeconomically disadvantaged adolescents despite similar levels of alcohol consumption, regardless of differences in drinking pattern or substance use. Future preventive strategies should prioritise young adolescents, including those who are most disadvantaged. Funding: Tryg Foundation (ID: 153539).

Decline in youth drinking in high-income settings: Implications for public health in low-income countries.

Declining drinking among youth in many high-income countries has attracted scholarly attention and debates. Still, researchers are yet to globalize such research or examine its public health implications for low-resource settings. This commentary has two interrelated purposes. First, using evidence from Nigeria, it highlights how declining youth drinking in high-income countries may impact public health in low-income countries. Second, it highlights the necessity for research to examine youth drinking behaviours simultaneously worldwide. The declining drinking trends among young people in high-income countries have occurred simultaneously with global alcohol corporations being more aggressive in low-income countries like Nigeria. Relatedly, alcohol corporations may employ evidence regarding declines in drinking to argue against implementing stringent policies or other effective interventions in Nigeria (and other low-income settings), claiming their apparent success in the falling drinking trends in high-income settings. The article argues that research on the drinking decline among young people should be globalized because without commensurate attempts to examine their drinking behaviours/trends worldwide simultaneously, public and/or global health may be harmed for the reasons explored in this article.

Do Australian adolescents with permission to drink at home engage in different alcohol use behaviours and experience more harms than those without such permission?

INTRODUCTION: Around half of Australian students aged 16-17 are estimated to have drunk alcohol in the past month, with 11% drinking at 'risky' levels. This study investigated: (i) how many Australian adolescents aged 16-17 had parental permission to drink at home in 2016/17 and whether prevalence differed by adolescent sex; (ii) whether adolescents allowed to drink at home had drunk more recently and were drinking greater quantities; (iii) if adolescents allowed to drink at home experienced more alcohol-related harms; and (iv) if parental drinking patterns were associated with permitting adolescents to drink at home. METHODS: Data from Wave 7 of the Longitudinal Study of Australian Children were used. Descriptive and bivariate analyses addressed Aims i-iii. Nested multivariable logistic regression models addressed aim iv. RESULTS: In 2016/17, 28% of Australian adolescents aged 16-17 were allowed to drink alcohol at home. More adolescents with permission had drunk alcohol in the past month (77% vs. 63% of those without permission). There was no difference in quantity of alcohol consumed in the past week between groups. More adolescents allowed to drink at home had experienced alcohol-related harm compared to those without permission (23% vs. 17%). In multivariable analyses, alcohol consumption by primary parents was associated with an increased likelihood of allowing adolescents to drink at home. DISCUSSIONS AND CONCLUSIONS: In order to reduce adolescent alcohol use and associated harms, parents should avoid permitting alcohol use among adolescents at home. Frequent (twice or more/week) primary parental alcohol consumption was especially associated with greater odds of allowing adolescents to drink at home.

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.

Inter-ethnic differences in self-reported alcohol-related harm to children in Han vs. Yi ethnic minority households in Yunnan Province, China.

China is a multi-ethnic country, but inter-ethnic disparities in alcohol-related harm to children have not been described. In this study, we assessed differences in prevalence of self-reported alcohol-related harm to children in Yi and Han households in Chuxiong Yi Prefecture, Yunnan Province, China. We conducted a cross-sectional study among caregivers in households with a child age less than 18 years using structured questionnaire interview. Participants included 241 Yi caregivers and 610 Han caregivers (overall refusal rate = 1.1%). Heavy drinking was more common in Yi households than Han households (41.9% vs. 30.8%, respectively), but there was no difference in alcohol-related harm to children (21.2% vs. 17.9%; Adjusted OR = 0.98; 95% CI = 0.65, 1.46). Caveats such as social desirability in reporting sensitive issues and the cross-sectional study design should be considered in the interpretation of the study findings.

Age, period and cohort effects on alcohol-related risky behaviours in Australia from 2001 to 2016.

AIMS: The aim of this study is to examine age, period and birth cohort trends in the prevalence of any alcohol-related risky behaviour and to compare these trends between men and women. DESIGN AND SETTING: We used an age-period-cohort analysis of repeated cross-sectional survey data from the Australian National Drug Strategy Household Survey from 2001 to 2016. PARTICIPANTS: Participants were 121 281 people aged 14-80 years who reported consuming alcohol in the past 12 months. MEASUREMENTS: Any risky behaviour undertaken while under the influence of alcohol in the past 12 months (e.g. operating a motor vehicle) was measured: male or female. FINDINGS: Controlling for age and cohort, cubic spline models showed that any alcohol-related risky behaviour declined with time among participants who consumed alcohol [2016 versus 2007 rate ratio (RR) = 0.80, 95% confidence interval (CI) = 0.76-0.84]. Risky behaviour peaked in the 1954 birth cohort (1954 versus 1971 RR = 1.42, 95% CI = 1.30-1.55) and then steadily declined with more recent birth cohorts (2002 versus 1971 RR = 0.32, 95% CI = 0.27-0.39). Risky behaviour peaked at age 21 years, followed by steady decline and stabilization at approximately age 70 years. Males were overall twice as likely as females to report alcohol-related risky behaviour (RR = 2.10, 95% CI = 1.84-2.39), but this effect was smaller in cohorts born after 1980 [1980 prevalence rate ratios (PRR) = 2.09, 95% CI = 1.81-2.43; 2002 PRR = 1.31, 95% CI = 1.03-1.68]. CONCLUSIONS: Alcohol-related risky behaviour in Australia has declined generally since 2001, with rates for recent cohorts having the sharpest decline. Risky behaviour remains most prevalent in young adults, and the male-female gap in risky behaviour is closing for more recent birth cohorts. These trends are consistent with alcohol consumption trends observed in Australia and world-wide.

Clarifying rural-urban disparities in alcohol-related emergency department visits and hospitalizations in Ontario, Canada: A spatial analysis.

PURPOSE: Rates of alcohol-related harm are higher in rural versus urban Canada. This study characterized the spatial distribution and regional determinants of alcohol-related emergency department (ED) visits and hospitalizations in Ontario to better understand this rural-urban disparity. METHODS: This was a cross-sectional spatial analysis of rates of alcohol-related ED visits and hospitalizations by Ministry of Health subregion (n = 76) in Ontario, Canada between 2016 and 2019. Regional hot- and cold-spots of alcohol-related harm were identified using spatial autocorrelation methods. Rurality was measured as the population weighted geographic remoteness of a subregion. The associations between rurality and rates of alcohol-related ED visits and hospitalizations were evaluated using hierarchical Bayesian spatial regression models. FINDINGS: Rates of alcohol-related ED visits and hospitalizations varied substantially between subregions, with high rates clustering in Northern Ontario. Overall, increasing rurality was associated with higher subregion-level rates of alcohol-related ED visits (males adjusted relative rate [aRR]: 1.67, 95% credible interval [CI]: 1.49-1.87; females aRR: 1.78, 95% CI: 1.60-1.98) and hospitalizations (males aRR: 1.34, 95% CI: 1.24-1.45; females aRR: 1.59, 95% CI: 1.45-1.74). However, after the province was separated into Northern and Southern strata, this association only held in Northern subregions. In contrast, increasing rurality was associated with lower rates of alcohol-related ED visits in Southern subregions (males aRR: 0.87, 95% CI: 0.79-0.96; females aRR: 0.88, 95% CI: 0.81-0.97). CONCLUSIONS: There are regional differences in the association between rurality and alcohol-related health service use. This regional variation should be considered when developing health policies to minimize geographic disparities in alcohol-related harm.

Improving Campus Alcohol Policies Through Assessment and Scoring.

Excessive alcohol consumption is responsible for more than 1,500 deaths annually among college students, of whom more than one in three report having been drunk during the past 30 days. Campus alcohol policies offer a first line of defense against excessive alcohol use but have received little systematic attention in the research literature. The research team previously developed a taxonomy of campus alcohol policies and sanctions, ranked in order of effectiveness, and assessed the accessibility, clarity, and effectiveness of policies at 15 post-secondary educational institutions. Herein we describe the process of reporting those assessments back to the 15 institutions, providing them with recommendations and technical assistance on how to improve their policies, and then re-assessing school alcohol policies for effectiveness and clarity. Conversations with primary points of contact at each school provided further insight into the process of assessing and improving campus alcohol policies. Of the 15 schools assessed, 11 added more effective policies, and four added more effective consequences during the 2 years following receipt of reports on the assessment. Campuses have control over their own policies, and greater attention to them from researchers and practitioners could better maximize their potential for enhancing student health and safety and supporting student success.

Developing an alcohol harm prevention research agenda in West Africa: a mixed methods approach.

Research on alcohol use and its associated harm is scarce in West Africa. To mitigate the knowledge gap and to build momentum for future research, we determined research priorities for alcohol prevention among stakeholders across nine countries in West Africa. We analyzed a cross-sectional survey conducted in the fall of 2020, distributed by the West African Alcohol Policy Alliance (WAAPA). Respondents represented members of the WAAPA, members of intra-country alliances on alcohol and other stakeholders reached by snowball sampling. Quantitative and qualitative survey measures, adapted from the WHO's readiness assessment for the prevention of child maltreatment or developed by the research team, assessed research priorities, awareness of alcohol-related harm, risk factors and data availability. We mapped the qualitative answers into general themes and conducted descriptive analysis on the quantitative responses. Participants outlined two general themes to focus on: (i) alcohol use among children and youth and (ii) the health-related impact of alcohol. The most commonly listed types of alcohol-related harms pertained to acute consequences, such as gender-based violence, injuries, traffic crashes and child maltreatment. Risk factors for alcohol-related harm included limited enforcement of alcohol policies, cheap alcohol, and limited knowledge. Strengthening the capacity for addressing these research priorities will be key in reducing alcohol-related harm in West Africa. The goal of these research priorities is to drive research that informs advocacy, programs and policy. In addition to research, an awareness campaign of the health effects of alcohol is urgently needed.

Association of supply sources of alcohol and alcohol-related harms in adolescent drinkers: the baseline characteristics of a high school cohort across Thailand.

BACKGROUND: The main objective of this study was to investigate the association between parental supply of alcohol, alcohol-related harms, and the severity of alcohol use disorder in Thai 7th grade middle school students. METHODS: A cross-sectional descriptive study obtained the baseline data from the project named the Thailand Parental Supply and Use of Alcohol, Cigarettes & Drugs Longitudinal Study Cohort in Secondary School Students in 2018. The sample size was 1187 students who have ever sipped or drank alcohol in the past 12 months. Pearson's Chi square, binary logistic regression, and ordinal logistic regression are applied in the analysis. RESULTS: A single source of parental supply is not significantly associated with any alcohol-related harm and the severity of alcohol use disorder, while parental supply with peers and siblings supply of alcohol plays an important role in both outcomes. The increasing number of sources of alcohol supply increases the risk of alcohol-related harm and the severity of alcohol use disorder. Other risk factors found in both associations included binge drinking, alcohol flushing, low household economic status, distance from the student's family, and poor academic performance. Gender, exposure to alcohol ads on social media and location of residency were not associated with alcohol-related harms or severity of alcohol use disorder. CONCLUSIONS: The results did not support parental guidance in teaching or giving children a drink or sip of alcohol within family to prevent related harms when drinking outside with their peers.

Prevalence of Alcohol-Related Harms in Yi and Han Ethnic Groups in a Prefecture in Yunnan Province, China.

BACKGROUND: Although differences in the prevalence of alcohol-related harm between ethnic minority and majority groups have been reported in many countries, such data are scarce in China. The findings of such assessment can provide empirical data to inform stakeholders in prioritization and allocation of resources for programs to manage and control alcohol-related problems. The objective of this study is to compare the prevalence of alcohol-related harm from others among Han and Yi populations in the Chuxiong Yi Autonomous Prefecture, Yunnan Province, China. METHOD: We conducted a cross-sectional study in 1370 households from 21 villages. Enumerators used convenient sampling to recruit one person aged 18 years or older from each selected household, obtained informed consent to participate, and conducted an interview using a structured questionnaire. The questionnaire included three parts: (1) demographic characteristics of the participant (including ethnic identity); (2) history of alcohol-related harm from other in the past 12 months, and; (3) drinking behaviors. We analyzed data using descriptive statistics and multivariate regression analyses, stratified by sex of the participant. RESULTS: The prevalence of experiencing alcohol-related harm from others in Han men, Yi men, Han females, and Yi females, were 69.9%, 62.1%, 75.3%, and 63.4%, respectively. The Han vs. Yi disparity was higher among females (Adjusted OR = 2.06; 95% CI = 1.41, 3.01) than males (Adjusted OR = 1.47; 95% CI = 1.05, 2.07). The most common type of harm was feeling scared or threatened (36.9% among males, 32.4% among females) and the least common type was financial difficulty (3% among males, and 3.3% among females). CONCLUSIONS: Yi ethnic minorities in Yunnan Province had lower prevalence of alcohol-related harm from others than Han persons in the same region. However, measurement and translation-related issues of the study instrument and limited generalizability should be considered as caveats in the interpretation of the study findings.

Evaluation of the national sobriety checkpoints program in Mexico: a difference-in-difference approach with variation in timing of program adoption.

BACKGROUND: Up to a third of global road traffic deaths, and one in five in Mexico, are attributable to alcohol. In 2013, Mexico launched a national sobriety checkpoints program designed to reduce drink-driving in municipalities with high rates of alcohol-related collisions. Our study measured the association between the sobriety checkpoints program and road traffic mortality rates in 106 urban municipalities. METHODS: We leveraged data from the Salud Urbana en America Latina (SALURBAL), which compiles health and environmental data from cities with over 100,000 residents. Death data from 2005 to 2019 (i.e., outcome) were from official vital statistics. Among 106 Mexican municipalities defined as priority areas for intervention, 54 adopted the program (i.e., treatment) in 2013, 16 municipalities did so in 2014, 16 in 2015, 10 in 2016, 7 in 2017, and 2 in 2019. We used a difference-in-difference approach with inverse probability weighting adapted to a context where program adoption is staggered over time. RESULTS: There was a 12.3% reduction in road traffic fatalities per 10,000 passenger vehicles in the post-treatment period compared to the pre-treatment period (95% Confidence Interval, - 17.8; - 6,5). There was a clear trend of decline in mortality in municipalities that adopted the program (vs. comparison) particularly after year 2 of the program. CONCLUSIONS: In this study of 106 municipalities in Mexico, we found a 12.3% reduction in traffic fatalities associated with the adoption of sobriety checkpoints. There was a clear trend indicating that this association increased over time, which is consistent with sustained changes in drink-driving behavior. These findings provide support and insight for efforts to implement and evaluate the impact of sobriety checkpoint policies across Latin America.

Australian first-year university college residents' alcohol consumption and alcohol-related harms.

Aim: The study sought to develop an understanding of Australian first-year university residential college students' alcohol consumption, their experience of alcohol-related harms and their alcohol knowledge. Method: Students were surveyed during Orientation Week in 2015 (N = 84, men 36%) and again in 2017 (N = 97, men = 45%) using the Alcohol Use Disorders Identification Test (AUDIT) to measure alcohol consumption, and purpose-designed measures of alcohol-related harms and alcohol knowledge. Results: The mean AUDIT score across the two cohorts was 10.79, placing these first-year college residents at much riskier consumption levels than their Australian undergraduate and international peers. Three-quarters were consuming alcohol at hazardous/harmful levels. They reported frequent occurrence of alcohol-related harms and, given the higher levels of drinking, these were for the most part more pronounced than in other studies: vomiting (73%), memory loss (55%), regretting their actions when drinking (41%), not having enough money because of money spent on alcohol (31%), doing something dangerous just for fun (29%), being injured (27%), poor performance at work (22%), poor physical health (21%), loss of consciousness (20%), and having sexual encounters they later regretted (19%). Poor knowledge of standard drink measures, particularly in relation to blood alcohol concentration, was also indicated. Conclusions: The study highlights the worrying occurrence of hazardous/harmful drinking in Australian first-year university residential college students and high levels of alcohol-related harms experienced by these residents. It also highlights poor alcohol knowledge and the need for early intervention prior to and within university college residences to minimise harm.

Analysis of AUDIT Domains in Freshman Students in Spain: Three Cross-Sectional Surveys (2005, 2012 and 2016).

Purpose: We aimed to evaluate changes in the frequency of drinking, alcohol dependence and alcohol-related harm in freshman college students from 2005, 2012 and 2016, and identify risk-associated factors. Method: A cross-sectional study involving 5009 freshman students was carried out in Spain in 2005, 2012 and 2016. The Dimensions of Alcohol Use Disorders Identification Test (frequency of drinking, symptoms of dependence and alcohol-related harm) was analysed. Adjusted relative risks (RRs) and their 95% confidence intervals were estimated using negative binomial regression. Results: Place of residence, positive expectancies and early onset of alcohol consumption continue to be crucial conditions for developing patterns of risky consumption, alcohol dependence and harm. Women and men were more vulnerable to alcohol harm and dependence when living away from home, having higher economic status and positive alcohol expectancies. Cohorts from 2012 and 2016 were at lower risk of risky alcohol consumption. Men belonging to the 2012 and 2016 cohorts were at lower risk of alcohol negative consequences compared with the 2005 cohort. However, women remained vulnerable over time to alcohol dependence and harm. Starting drinking after 16 protects them both from alcohol dependence and harm. Conclusions: Women are more vulnerable to alcohol dependence and harm in recent cohorts of freshmen. Limiting access to alcohol at a younger age and working on false positive expectancies could benefit freshmen by avoiding alcohol damage and alcohol dependence.
