Alcohol, youth and sport: recommendation and good practice examples from the FYFA European project.

Focus on Youth Football and Alcohol (FYFA) is a European project (EC, 3rd Health Program, HP-PJ-2016) involving research institutions from Belgium, Finland, Italy, Poland, Slovenia and the UK. The Istituto Superiore di Sanità (ISS), was the project leader of Work Package 5: "Review of national policies and practice in six Member States related to alcohol, young people, sport, marketing and football." The aim of WP5 was to determine the status quo of the policies and practices to reduce heavy episodic drinking related to young people, alcohol and sport at national level. This work investigates knowledge, attitudes and perceptions of experts from sport settings and from the prevention area giving insights on the perceived obstacles and facilitators, whenever available, to promote strategies to reduce alcohol related harm in youth within sport contexts. The presented work describes laws, regulations and attitudes. Furthermore, the results help identifying areas requiring development, highlighting examples of good practices. It emerges that prevention of alcohol-related harm to youth is important within sport settings and should be a priority for all FYFA countries. Despite the presence of regulations, there is a low level of knowledge and enforcement at national level and in the sport contexts; and there is the need of cooperation across organizations to implement alcohol policies for youth within sport settings. More efforts and resources are needed to overcome the main obstacles for effective implementation of alcohol policies, such as regulations on advertising and sponsorship, and alcohol selling, serving and consumption for young players. It is necessary to implement information strategies, prevention initiatives, training programs and to support the dialogue between sporting and prevention settings.

The Right Time and Place: A New Approach for Prioritizing Alcohol Enforcement and Prevention Efforts by Combining the Prevalence and the Success Rate for Minors Purchasing Alcohol Themselves.

OBJECTIVE: In the Netherlands, enforcement of the alcohol age limit is low and inconsistent because of limited resources. A solution is to optimize the efforts of enforcement officers by prioritizing ways in which they regulate commercial alcohol availability. This could increase compliance by sellers, curbing commercial availability. The objective of this study is to present the development of a commercial alcohol availability estimate (CAAE) for all vendor types selling alcohol and to propose a priority ranking. METHOD: A multi-method design was used, combining data (collected in 2015) from national studies reporting behavior of minors purchasing alcohol themselves and the success rate (noncompliance) of alcohol vendors (interviewing 510 minors by telephone and conducting 1,373 purchase attempts of alcohol by minors, respectively). Descriptive data and the development of the CAAE are presented. RESULTS: Compared with other vendor types (e.g., sports bars or supermarkets), bars/cafes/discos scored highest on the CAAE, indicating that 7.7% of 16- to 17-year-olds in the survey reported successfully purchasing their own alcohol at this vendor type. CONCLUSIONS: To control commercial alcohol availability efficiently for minors in the Netherlands, our estimates suggest that enforcement and prevention efforts should prioritize bars/cafes/discos. However, local authorities should also consider local circumstances and maintain a base amount of attention for all vendor types. Ultimately, the CAAE has the potential to improve enforcer capacity and efficiency in policing commercial alcohol regulation, and prevention workers could align their interventions or campaigns to high-ranked vendor types.

Problemas de información a los padres y tutores en la asistencia a urgencias en menores de 14 a 17 años por consumo de sustancias psicoactivas / Issues with information given to parents and guardians on medical care in the emergency department relating to minors aged from 14 to 17 years due to psychoactive substance

INTRODUCCIÓN: El cumplimiento de los deberes de la patria potestad exige a los padres y/o tutores estar informados de aquellos aspectos relevantes relacionados con la salud del menor. La legislación actual reconoce la autonomía a partir de los 16 años o menores emancipados. En este trabajo se analiza la información que reciben los padres o tutores legales de los menores mayores de 14 años que acuden a un servicio de urgencias hospitalario general de tercer nivel por intoxicación aguda por alcohol y otras drogas de abuso incluidos medicamentos como las benzodiacepinas si se consumen con fines recreativos. MATERIAL Y MÉTODOS: Se revisaron las historias clínicas de los menores atendidos en el servicio de urgencias de un hospital de tercer nivel durante los años 2016 y 2017 para conocer la información referida a los padres y se entrevistó a los médicos y enfermeros de dicho servicio para conocer la información que daban a los padres/tutores. RESULTADOS: En las historias clínicas en las que se citaba que el menor iba acompañado por amigos (11,5%), 5 de ellas (9,6%) no especificaban si se había realizado el aviso a padres/tutores. De las 26 historias clínicas (50%) en las que no había especificación del acompañamiento, en 22 (42,3%) tampoco existía especificación del aviso. Mientras que 28 de los 35 encuestados (80%) afirma avisar siempre que el menor no hubiera ido acompañado por sus padres o tutores. CONCLUSIONES: Se pone de manifiesto la existencia de una falta de información de tipo asistencial relativa al aviso a padres/tutores, así como una discrepancia entre los datos proporcionados por los médicos y enfermeros y los obtenidos en las historias clínicas

BACKGROUND: In accordance with parental legal duties, parents and guardians should be informed about health issues relevant to child health. Current Spanish legislation acknowledges autonomy from 16 years or emancipated minors. This study analyses the information given to the parents or legal guardians of minors over 14 years of age attending a tertiary-level general hospital emergency department on psychoactive substance intoxication (alcohol, cannabis, benzodiazepines). MATERIAL AND METHODS: The medical records of minors treated in the emergency department of a tertiary-level hospital, between 2016 and 2017, were reviewed. A survey of medical and nursing professionals from the emergency services was also conducted. RESULTS: Of the medical records that mentioned that the minor attended the emergency department with friends (11.5%), 5 (9.6%) did not specify if the parents or guardians were called. Of the 26 medical records (50%) in which there was no mention of whether if the minor attended alone or accompanied, 22 (42.3%) made no mention of informing parents. The study data show that 28 of the 35 respondents (80%) always notified if the minor had not been accompanied to the emergency department by a parent or guardian. CONCLUSIONS: There is lack of information relating to informing parents/guardians, as well as a discrepancy between the data provided by health professionals and the medical reports analysed

A restrictive alcohol social supply law change is associated with less supply to friends under 18 years.

INTRODUCTION AND AIMS: This study aimed to assess the early impacts of a 2013 law change to restrict the social supply of alcohol to under 18s in New Zealand by assessing changes in social suppliers' behaviour. DESIGN AND METHODS: National surveys of drinkers aged 16-65 years were collected before (2013) and after (2015) the law change. Suppliers were asked: to whom they supplied alcohol, how often and how much; if the supplier thought the alcohol they provided would be shared; whether the supplier had permission to supply from parent/guardian, and if they supervised their supply. General estimating equation models were used to conduct analyses. RESULTS: Sons and daughters were commonly supplied to, as were friends, but friends were supplied greater quantities on average [13 drinks compared to four drinks for sons/daughters (at baseline)]. Following the law change, friends were less commonly supplied to (8% decrease), were supplied with fewer drinks (down from 13 to 11 drinks) and there was greater supervision of social supply to friends (16% increase) (and to other relatives). However, the number of drinks supplied by parents increased from four to six drinks. DISCUSSION AND CONCLUSIONS: There was evidence of some early reductions in social supply in relation to the law change, in particular where the legislation aimed to have effect; specifically, less supply to friends under 18 years. We found no effect of the new law on parental supply. As quantities supplied are still very high, further policy restriction and public health interventions would be appropriate.

Associations Between Alcohol Policies and Adolescent Alcohol Use: A Pooled Analysis of GSHS and ESPAD Data.

AIMS: Alcohol-attributable harm remains high worldwide, and alcohol use among adolescents is particularly concerning. The purpose of this study is to determine the effect of national alcohol control policies on adolescent alcohol use in low-, middle- and high-income countries and improve on previous cross-national attempts to estimate the impact of alcohol policy on this population. METHODS: Data on adolescent (n = 277,110) alcohol consumption from 84 countries were pooled from the Global School-based Health Survey and the European School Survey Project on Alcohol and Other Drugs. Alcohol use measures included lifetime alcohol use, current (past 30 days) alcohol use and current (past 30 days) binge drinking. Information on national alcohol control policies was obtained from the World Health Organization's Global Information System on Alcohol and Health and scored for effectiveness. Main effects were estimated using two-level, random intercept hierarchical linear models, and the models were adjusted for sex and age of the participants, and pattern of drinking score, gross domestic product based on purchasing power parity and study at the country level. RESULTS: Availability (OR [95% CI] = 0.991 [0.983, 0.999]), marketing (OR [95% CI] = 0.994 [0.988, 1.000]) and pricing (OR [95% CI] = 0.955 [0.918, 0.993]) policies were inversely associated with lifetime drinking status. Pricing policies were also inversely associated with current binge drinking status among current drinkers (OR [95% CI] = 0.939 [0.894, 0.986]). There were no associations between the included alcohol policies and current drinking status. CONCLUSIONS: Strong availability, marketing and pricing policies can significantly and practically impact adolescent alcohol consumption.

Is changing the minimum legal drinking age an effective policy tool?

In year 1991, regional governments in Spain started a period of implementation of a law that rose the minimum legal drinking age from 16 to 18 years old. To evaluate the effects of this change on the consumption of legal drugs and its related morbidity outcomes, we construct a regional panel dataset on alcohol consumption and hospital entry registers and compare variation in several measures of prevalence between the treatment group (16-18 years old) and the control group (20-22 years old). Our findings show important differences by gender. Our main result regarding overall drinking prevalence shows a reduction of -21.37% for the subsample that includes males and females altogether. This effect on drinking is mainly driven by a reduction of -44.43% in mixed drinks and/or liquors drinking prevalence corresponding to the subsample of males. No causal effects regarding overall smoking prevalence and hospitalizations due to alcohol overdose or motor vehicle traffic accidents were found. To our knowledge, this is the first paper providing evidence on gender-based differences to policies aimed at reducing alcohol consumption. Our results have important policy implications for countries currently considering changes in the minimum legal drinking age.

Patient-level factors are more salient than a legislation prohibiting minors in bars in predicting unintentional injury hospitalizations.

BACKGROUND: Alcohol related homicide, suicide and aggravated assault represent the largest costs for the state of Illinois. Previous research has examined the impact of some alcohol-related policies on youth alcohol use and alcohol-related harm in the United States but findings have been mixed. To our knowledge, no study has provided a detailed epidemiology of the relationship between the impacts of alcohol policies on unintentional injury in Illinois. Therefore, the purpose of this study is to determine whether a legislation that prohibit minors under 21 years old in establishments that serve alcohol is more salient than individual level factors in predicting hospitalization for traumatic unintentional injuries. METHODS: A retrospective observational study of data abstracted from 6,139 patients aged 10 to 19 hospitalized in Illinois Level I and Level II trauma centers. Patient data from 2006 to 2015 was linked with the city-level alcohol-related legislation (n = 514 cities). The response variable was whether a patient tested positive or negative for blood alcohol concentration (BAC) at the time of admission. Mixed-effects logistic regression analyses were conducted to model the patient and city level legislation effect of having a positive BAC test result on hospitalizations after adjusting for the legislation and patient factors. RESULTS: After adjustment, patients aged 15 to 19 and white patients who tested positive for BAC at the time of admission had the greater odds of hospitalization for traumatic alcohol-related unintentional injuries compared to patients who had a negative BAC test result. However, odds of hospitalization decreased for female patients and for those with private insurance, and over time, but a significant decrease in such hospitalizations occurred during 2010, 2014 and 2015. The alcohol-related legislation of interest was not a significant predictor of traumatic alcohol-related unintentional injury hospitalization. CONCLUSIONS: Patient-level covariates were significant predictors of traumatic alcohol-related unintentional injury hospitalization; an alcohol-related legislation may not reduce hospitalizations for young patients aged 10 to 19. Therefore, to prevent underage drinking and consequences, interventions should target sex/gender, race/ethnicity and focus on both individual and environmental strategies.

Alcohol Use by Youth.

Alcohol use continues to be problematic for youth and young adults in the United States. Understanding of neurobiology and neuroplasticity continues to highlight the potential adverse impact of underage drinking on the developing brain. This policy statement provides the position of the American Academy of Pediatrics on the issue of alcohol and is supported by an accompanying technical report.

State alcohol policies, taxes, and availability as predictors of adolescent binge drinking trajectories into early adulthood.

BACKGROUND AND AIMS: A number of alcohol policies in the United States have been presumed to reduce underage youth drinking. This study characterized underage youth binge-drinking trajectories into early adulthood and tested associations with the strength of the alcohol policy environment, beer excise taxes and number of liquor stores. DESIGN: Longitudinal cohort study. SETTING: United States. PARTICIPANTS: A national cohort of 10th graders in 2010 (n = 2753), assessed annually from 2010 to 2015. MEASUREMENTS: Participants reported on their 30-day binge drinking [defined as consuming five or more+ (for boys) or four or more (for girls) drinks within 2 hours]. We scored the strength of 19 state-level policies at baseline and summarized them into an overall score and two subdomain scores. We also assessed state beer excise taxes (dollars/gallon) and linked the number of liquor stores in 1 km to the participants' geocoded address. FINDINGS: We identified five binge-drinking trajectories: low-risk (32.9%), escalating (26.1%), late-onset (13.8%), chronic (15.1%) and decreasing (12.0%). Lower overall alcohol policy strength was associated with increased risk of being in the escalating versus low-risk binge-drinking class [relative risk ratio (RRR) = 1.44 per 1 standard deviation (SD) in policy score; 95% confidence interval (CI) = 1.17, 1.77)]. Higher beer excise taxes were associated with a reduced risk of being in the escalating class (RRR = 0.22 per 1-dollar increase; 95% CI = 0.09, 0.50). The number of liquor stores was not significantly associated with any binge-drinking trajectory. CONCLUSIONS: In the United States, stronger state alcohol policies and higher beer excise taxes appear to be associated with lower risk of escalating alcohol consumption trajectories among underage youth.

The role of consumer age and financial profit in vendor compliance for underage alcohol sales.

Age limit restriction for risky products is widely implemented as an instrument to improve public health. To study reasons for vendor (non-)compliance this 2 (underage vs. adult consumer) × 2 (low vs. high profit) field experimental research was conducted. Trained mystery shoppers conducted 218 alcohol purchase attempts. ID checks and compliance were significantly higher when financial profit was low (74% ID checks; 67% compliance) compared with the high-profit conditions (26%; 18%). There were no significant differences between the adult and underage consumer conditions. The motivation to comply appears to be the crucial factor, and enforcement needs to be intensified.

Assessing the impacts of minimum legal drinking age laws on police-reported violent victimization in Canada from 2009 to 2013.

BACKGROUND/AIM: Given that alcohol-related victimization is highly prevalent among young adults, the current study aimed to assess the potential impacts of Minimum Legal Drinking Age (MLDA) laws on police-reported violent victimization events among young people. DESIGN: A regression-discontinuity (RD) approach was applied to victimization data from the Canadian Uniform Crime Reporting 2 (UCR2) Incident-based survey from 2009-2013. Participants/cases: All police-reported violent victimization events (females: n = 178,566; males: n = 156,803) among youth aged 14-22 years in Canada. MEASUREMENTS: Violent victimization events, primarily consisting of homicide, physical assault, sexual assault, and robbery. RESULTS: In comparison to youth slightly younger than the drinking age, both males and females slightly older than MLDA had significant and immediate increases in police-reported violent victimization events (females: 13.5%, 95% CI: 7.5%-19.5%, p < 0.001; males: 11.6%, 95% CI: 6.6%-16.7%, p < 0.001). Victimizations occurring in the evening rose sharply immediately after the MLDA by 22.8% (95% CI: 9.9%-35.7%, p = 0.001) for females and 19.3% (95% CI: 11.5%-27.2%, p < 0.001) for males. Increases in violent victimization immediately after MLDA were most prominent in bar/restaurant/open-air settings, with victimizations rising sharply by 44.9% (95% CI: 29.5%-60.2%, p < 0.001) among females and 18.3% (95% CI: 7.7%-29.0%, p = 0.001) among males. CONCLUSIONS: Young people gaining minimum legal drinking age incur immediate increases in police-reported violent victimizations, especially those occurring in the evening and at bar/restaurant/open-air settings. Evidence suggests that increasing the MLDA may attenuate patterns of violent victimization in newly restricted age groups.

Can vendors' age limit control measures increase compliance with the alcohol age limit? An evaluation of measures implemented by three Dutch liquor store chains.

BACKGROUND: Dutch liquor store (off license) chains have voluntarily developed and implemented age limit control measures to increase compliance with the Licensing and Catering Act (LCA), aimed at prohibiting vendors from selling alcohol to minors (<18 years old). This study investigates differences between three liquor store chains in their style of self-regulation and how that affects compliance with the LCA in four domains (capturing processes in age verification, instructing staff, monitoring performance/providing feedback and imposing consequences). METHODS: A mixed-method design was used. In depth-interviews (n = 3) were conducted with chains' head office managers, gaining insight into control measures. Survey (n = 372) research was conducted to measure liquor store owners' perceptions of implementation. Mystery shop (n = 387) research was conducted to measure compliance of store owners with the LCA. Survey and mystery shopping data was linked (n = 179) for the indicated perceived risk of inspection. RESULTS: The interviews indicated that control measures differ across chains in comprehensiveness and degree of implementation, survey results showed corresponding differences across the chains. Linked results showed that liquor store owners who perceive a very high risk of inspection, showed higher ID requesting rates (chain 2 and 3: 93% and 99%) and compliance rates (chain 2 and 3: 77% and 86%), respectively. This effect may be amplified by a set of measures (e.g., by implementing age verification systems, increasing training, monitoring performances and/or imposing consequences) and could result in higher ID request rates (chain 1: 54% versus chain 2 and 3: both 95%) and compliance rates (chain 1: 35% versus chain 2 and 3: both 80%). CONCLUSION: A comprehensive and systematic implementation of specific combinations of control measures in all four domains resulted in high compliance rates up to 80%. Nevertheless, the expectation is that this effect can only be attained when complemented by external government enforcement efforts.

De nuevo sobre la venta y consumo de bebidas alcohólicas a menores en el Derecho español / Back to the sale and consumption of alcoholic drinks to and by minors in Spanish law

En 2018, el consumo de alcohol por los menores de edad sigue siendo un grave problema de salud pública en España. Por ello, volvemos a reflexionar sobre los cambios legislativos propuestos en la normativa estatal sobre la materia y su posible eficacia tanto en la protección de la infancia y la adolescencia como de la salud y prevención de las drogodependencias. También exponemos como esta problemática ha sido abordada, con diferentes perspectivas, por las normas de las Comunidades Autónomas

In 2018, underage drinking continues to be a serious public health problem in Spain. We therefore go back to reflect on the legislative changes proposed in the state regulation on the subject and their possible effectiveness in both the protection of childhood and adolescence as well as in health and prevention of drug dependencies. We also set forth how this problem has been addressed, with different perspectives, by the legislation of Autonomous Communities

Minimum Legal Drinking Age and Youth Health: Evidence From Japan.

OBJECTIVE: Recent studies showed that reducing the minimum legal drinking age (MLDA) could cause negative health outcomes among youth. This evidence was drawn primarily from a limited set of geographical regions. This study seeks to widen available evidence by using data from Japan, where the government started considering reducing the MLDA from 20 to 18. METHOD: Using a regression discontinuity design, we compared emergency service event rates related to alcohol intoxication and mortality rates through external causes between those who were slightly younger and older than the age of 20. RESULTS: We showed that granting legal access to alcohol at age 20 doubled the use of emergency services used for alcohol intoxication but had little impact on mortality as measured by traffic fatalities, suicide, and other accidents. CONCLUSIONS: Our findings suggest that lowering the MLDA in Japan will increase (potentially reckless and excessive) drinking behavior among young adults ages 18 and 19 but will not increase their mortality from accidents.

Effects of a responsible retailing mystery shop intervention on age verification by servers and clerks in alcohol outlets: A cluster randomised cross-over trial.

INTRODUCTION AND AIMS: Clerks and servers at alcohol establishments often fail to verify age. Using mystery shoppers to provide performance feedback is one approach to improving age verification. Few controlled studies have evaluated mystery shop interventions. This paper reports on a cluster randomised cross-over trial of a mystery shop intervention in 16 communities in four US states. DESIGN AND METHODS: The intervention comprised monthly mystery shops after which clerks and servers received immediate feedback to reinforce age verification. Managers received monthly reports. Communities in each state were matched into pairs and, following a 3-month baseline, were randomly assigned within each pair to receive the intervention beginning after the fourth (Early Intervention) or the tenth (Delayed Intervention) mystery shop. On average, 17 (range = 14-20) randomly selected on-premises and 18 (range = 11-23) off-premises outlets participated in each community (N = 557). RESULTS: Fixed effects multi-level logistic regressions indicated that the intervention led to a two-fold increase in the odds of age verification, odds ratio (OR) = 2.05; P < 0.001; 95% confidence interval (CI) 1.76, 2.39. Overall, ID-checking increased from an average of 80% pre-intervention to 94-96% by the end of the program. Significant effects were found for on-premises, OR = 1.79; P < 0.001; 95% CI 1.43, 2.24, and off-premises establishments, OR = 2.29; P < 0.001; 95% CI 1.86, 2.82. DISCUSSION AND CONCLUSIONS: Mystery shop interventions can increase age verification for alcohol purchases and may be an effective supplement to compliance checks and responsible beverage service programs.

Alcohol drinking and problems in young populations: the challenge in Asia.

PURPOSE OF REVIEW: The current article reviews recent research (from 2016 onward) on drinking behaviors and alcohol-related problems among young people in Asia with an emphasis on population-based evidence. RECENT FINDINGS: Recent evidence concerning underage drinking in Asia was limited to certain countries and societies with most data derived from cross-sectional surveys. Measures of alcohol drinking or problems were less sophisticated. The prevalence of recent alcohol drinking varies widely with the highest estimates reported in Hong Kong and Korea (∼21%). Certain emotional, behavioral, and cognitive characteristics have been linked with increased drinking behaviors, including internalizing or externalizing problems. Parents (or family) are the most studied predictors within the domain of socioenvironmental characteristics, whereas little attention has been paid to the macro environments (e.g., media, alcohol advertisement, and alcohol control policy/regulations). SUMMARY: Research on underage drinking behaviors in Asia is urgently needed, particularly in some emerging markets. Follow-up studies with longitudinal measurements and large diverse samples will provide a better understanding of developmental stage-dependent and ever-changing macroenvironmental factors, as well as possible mechanisms.

Evaluation of a combination of community initiatives to reduce driving while intoxicated and other alcohol-related harms.

OBJECTIVES: In 2013, the community of Redlands, California, created an initiative using evidence-based strategies to deter driving under the influence (DUI), underage drinking and driving, public intoxication, and alcohol-related calls for service. The initiative, called "Responsible Redlands," included adopting a social host and a deemed approved local ordinance, using minor-decoy and shoulder-tap operations, increasing sobriety checkpoints and saturation patrols, conducting responsible beverage service (RBS) training, using identification (ID) scanners to spot false IDs, and a publicity campaign to urge neighbors to report loud drinking parties. The objectives of this study were to determine whether the initiatives were carried out as planned and to assess any impacts that may have occurred due to the combination of initiatives. METHODS: Data from the Redlands Police Department were used to assess the process evaluation. The Statistical Analysis System (SAS) was used to create contingency tables to compare before (2007-2012) and after (2013-2014) the intervention start date and to conduct time-series analyses and calculate chi-squared test statistics on five outcome measures: DUI arrests, underage drinking violations, public intoxication violations, alcohol calls for service, and place of last drink (POLD) data from alcohol violators. Data sources were from the Redlands Police Department: DUI arrests for drivers under age 21 years and drivers age 21 or older; alcohol-related calls for service; public intoxication citations; and place of last drink surveys. Comparable data from control communities in California were not available at the time of the analyses. RESULTS: Responsible Redlands Initiatives appeared to be carried out as planned. There was a statistically significant decrease in DUI arrests for drivers 21 and older from preintervention to postintervention (p < .001), in alcohol-related calls for service (p < .001), in loud music calls for service (p = .06), and in public intoxication citations (p < .001). There were decreases in underage drinking violations and in DUIs for under age 21 drivers, but the numbers were too small for chi-squared statistical tests. CONCLUSIONS: "Responsible Redlands" interventions were associated with several significant decreases in outcome measures from preintervention to postintervention. Communities that consider these initiatives in combination (social host and deemed approved ordinances; minor-decoy and shoulder-tap operations; DUI checkpoints and saturation patrols; RBS training; use of ID scanners and a public information campaign to report loud drinking parties) can expect to experience potential decreases in alcohol-related harm.

Adolescents' alcohol use and strength of policy relating to youth access, trading hours and driving under the influence: findings from Australia.

AIMS: To determine (i) whether the strength of Australian alcohol control policy in three domains (youth access, trading hours and drink driving) changed during the 2000s; and (ii) estimate associations between these policies and adolescent drinking after adjusting for television alcohol advertising exposures, alcohol outlet density, alcohol price changes, exposure to negative articles about alcohol in daily newspapers and adult drinking prevalence. DESIGN: Repeated cross-sectional surveys conducted triennially from 2002 to 2011. Multi-level modelling examined the association between alcohol control policies and drinking prevalence after adjusting for covariates. SETTING: Four Australian capital cities between 2002 and 2011. PARTICIPANTS: Students aged 12-17 years participating in a triennial national representative school-based survey (sample size range/survey: 9805-13 119). MEASUREMENTS: Outcome measures were: past month drinking and risky drinking (5+ drinks on a day) in the past 7 days. Policy strength in each of three domains (youth access, trading hours, drink-driving) were the key predictor variables. Covariates included: past 3-month television alcohol and alcohol-control advertising, alcohol outlet density, alcohol price change, negatively framed newspaper alcohol articles, adult drinking prevalence and student demographic characteristics. FINDINGS: During the study period, the strength of youth access policies increased by 10%, trading hours policies by 14% and drink-driving policies by 58%. Past-month and risky drinking prevalence decreased (e.g. past-month: 2002: 47.4% to 2011: 26.3%). Multivariable analyses that included all policy variables and adjusted for year, student and other covariates showed past-month drinking to be associated inversely with stronger trading hours policies [odds ratio (OR) = 0.80, 95% confidence interval (CI) = 0.69, 0.94], but not youth access (OR = 0.92 95% CI = 0.81, 1.04) or drink-driving (OR = 1.00, 95% CI = 0.93, 1.09). Risky drinking was associated inversely with stronger youth access policies (OR = 0.82, 95% CI = 0.69, 0.98), but not trading hours (OR = 0.85, 95% CI = 0.66, 1.09) or drink-driving (OR = 1.02, 95% CI = 0.90, 1.14) policies. CONCLUSIONS: Population-directed policies designed to reduce alcohol availability and promotion may reduce adolescents' alcohol use.

Increasing Parents' Awareness of Social Host Laws: A Pilot Study of Coalition Efforts.

States and municipalities across the U.S. are adopting social host ordinances (SHOs) to reduce alcohol use by underage youth in private settings. SHOs are most likely to be effective if parents and other adults are aware of them and they are enforced. We examined the association between a multi-media SHO awareness campaign in northern California municipalities and parents' awareness of SHOs and SHO enforcement. We collected survey data from 1798 parents in a northern California county in fall 2014; all municipalities within the county had SHOs. We conducted descriptive and logistic regression analyses to determine whether parents living in municipalities with a SHO awareness campaign were more likely to be aware of SHOs and SHO enforcement than parents in municipalities without such a campaign. Findings showed that 55.6% of parents in municipalities with a SHO awareness campaign were aware of SHOs compared to 35.7% in municipalities without a campaign. Parents in municipalities with a SHO awareness campaign were also more likely to be aware of SHO enforcement activities (16.3 vs. 8.7%). Regression analyses indicated significant positive associations between the SHO awareness campaign and parental awareness of SHOs and SHO enforcement when controlling for parents' attitudes related to youth drinking, parenting characteristics, normative beliefs regarding other parents' awareness and youth drinking, and demographic characteristics. These findings suggest that a multi-media awareness campaign implemented by coalitions was positively associated with parental awareness of SHOs and perceived SHO enforcement, which may help to prevent or reduce underage drinking.

Can technology really help to reduce underage drinking? New evidence on the effects of false ID laws with scanner provisions.

In Volume 36 of this journal, Yoruk (2014) uses data from the National Longitudinal Survey of Youth 1997 and finds that false ID laws with scanner provisions have large impacts on binge drinking participation, frequency of alcohol consumption and binge drinking frequency among minors. This paper reexamines how false ID laws with scanner provisions affect underage drinking. I first demonstrate that analyses based on NLSY97 data fail falsification exercises testing for significant pre-intervention effects, and that the estimated effects based on these data are highly sensitive to the inclusion of a lead term and to sample selection, which weakens confidence in the large estimated effects reported in Yoruk (2014). I then use data from the Youth Risk Behavior Surveillance System to show that false ID laws with scanner provisions have no effect on underage drinking behavior.
