Introduction: Low- and middle-income countries bear disproportionate burdens from excessive alcohol consumption, yet have fewer resources to identify and intervene with risky drinkers. Low-cost screening and brief intervention (SBI) models offer a tool for addressing this health problem and reducing disparities.

Methods: In this mixed-methods study, trained pseudo-patients visited health clinics in Zacatecas, Mexico, where a novel SBI model was used with trained nonmedical health educators (HEs) conducting SBI in waiting areas.

Objective: The objective of this study was to compare drink driving and related road safety issues in 2 urban areas of 6 countries and develop an equation for estimating the rate of crash underreporting to the police in urban areas of countries that lack this information.

Methods: This study is a secondary analysis of 1 to 2 waves of surveys in pairs of matched medium-sized cities in Belgium, Brazil, China, Mexico, South Africa, and Ohio, United States; the surveys supported evaluation of local alcohol harm reduction efforts. Data were from 2017 to 2019 except 2023 for Mexico.

Introduction: We investigated whether greater concentrations of on- and off-sale alcohol outlets were associated with crime and whether this association was moderated by COVID-19 shelter-in-place orders (SIP) that restricted on-premises consumption of alcohol.

Methods: Crimes (2019-2020) and addresses of licenced alcohol outlets in a medium-sized California city were geocoded within census block groups (N = 61). On- and off-sale alcohol outlet density was calculated as licenced outlets/2.

We examined associations of the 2016 legalization of recreational marijuana (RML) in California with marijuana and alcohol co-use among race/ethnic groups using successive cross-sections from 7, 9, and 11 graders ( = 3,319,329) in the 2010-11 to 2018-19 California Healthy Kids Surveys. Multilevel logistic regressions indicated a stronger positive association between RML and co-use among non-Hispanic/Latine White youth (OR = 1.21) relative to Hispanic/Latine (OR = 1.

This group-randomized trial assessed the effects of a universal prevention training curriculum for school administrators and teachers that focused on effective strategies to prevent adolescent substance use and related problems. Twenty-eight schools in three regions of Peru were randomly assigned to either an intervention or control condition (14 schools per condition). Repeated cross-sectional samples of 11 to 19-year-old students participated in four surveys from May 2018 to November 2019 (N = 24,529).

Objective: This study examined whether recreational marijuana legalization (RML) and local retail availability were associated with marijuana and alcohol use and co-use among adolescents.

Method: We investigated associations between RML and past-30-day marijuana and alcohol use and co-use, and moderating effects of retail availability of marijuana and alcohol, using data from the 2010-2011 to 2018-2019 California Healthy Kids Surveys (CHKS) of 9th and 11th grade students in 38 California cities.

Background: Adolescents who dual use ENDS with tobacco cigarettes are more likely to have an increased risk of developing dependence. Yet, little is understood about the factors driving dual use among adolescents. The current study sought to reveal the day-to-day socio-temporal contextual and community factors associated with adolescents' use of electronic nicotine delivery systems (ENDS), and how these factors predict dual use with tobacco cigarettes.

Background: This study examined the prevalence of screening and brief intervention (SBI) for alcohol use disorder (AUD) risk in samples of adult drinkers in three middle-income countries (Brazil, China, South Africa), and the extent to which meeting criteria for AUD risk was associated with SBI.

Methods: Cross-sectional survey data were collected from adult samples in two cities in each country in 2018. Survey measures included past-year alcohol use, the CAGE assessment for AUD risk, talking to a health care professional in the past year, alcohol use screening by a health care professional, receiving advice about drinking from a health care professional, and sociodemographic characteristics.

Background: The onset of alcohol use during adolescence is associated with concurrent and subsequent related problems. Research on drinking contexts that underly these key first-time experiences and how they differ by initiation type is needed. The current study examined the physical, social, and situational characteristics of three types of initiation: first drink, first heavy episodic drinking (HED), and first intoxication and considered variations between early and later initiating adolescents.

Introduction: In 2016, California enacted a law (T21) prohibiting tobacco product sales to individuals under 21 years of age. Given tobacco use disparities among sexual minority (SM) youth, this study investigated whether California's T21 law was differentially associated with changes in tobacco use for SM and non-SM adolescents.

Aims And Methods: Secondary analyses of California Healthy Kids Survey data from 2013-2014 to 2018-2019 for 7th, 9th, and 11th graders (N = 2 229 401).

Objective: Adolescents are more likely than young adults to use electronic nicotine delivery systems (ENDS), yet most of what is known is concluded from young adult ENDS use as young adults are easier to survey. Additionally, while evidence about the prevalence and trends of adolescent ENDS use comes from cross-sectional studies, ecological momentary assessment (EMA) studies provide greater detail about the ways in which adolescents vape and the environments that are favorable to adolescent vaping, providing important guidance for policy, prevention, and intervention.

Method: We conducted a 2-week EMA study with 50 adolescents to assess behaviors, contexts, and characteristics of ENDS use.

Background: Research on the effects of restricting bar opening hours and alcohol sales in middle-income countries is very limited. We assessed compliance with and possible effects of a law enacted in Zacatecas, Mexico on December 30, 2017 and implemented in 2018 and 2019 that established a 2 AM bar closing time and 10 PM cut-off for alcohol sales by off-premises stores.

Methods: Monthly observations of bars and off-premises stores and alcohol mystery shopping visits from 2018 to early 2020 were conducted to assess compliance with the law.

Background: There is a need for interventions that promote healthy decision making among adolescents and leverage the ongoing impact of parental relationships through older adolescence and young adulthood. These interventions should maximize adolescent engagement and be easily accessible to families in terms of cost, duration, and logistics related to participation.

Objective: This study aims to test the efficacy of the healthy relationships and sexual decision-making component of a web-based intervention for older adolescents and their parents, ascertain whether the efficacy varies by gender, and assess its efficacy over time.

Background: College student drinking in on-premises establishments has been associated with heavy alcohol consumption and a range of problems including assault, fighting, risky sex, and drinking and driving. Although more strictly enforcing overservice laws might reduce heavy drinking in on-premises establishments, law enforcement agencies have few resource-efficient tools for doing so, resulting in these laws seldom being enforced.

Objectives: In this paper, we report the results of an evaluation of the Stop Service to Obviously-impaired Patrons (S-STOP) program that was implemented in 303 bars and restaurants in 18 university communities in California using a randomized cross-over design (early vs.

We investigated whether recreational marijuana legalization (RML) in Oregon in 2015 and recreational marijuana and alcohol retail outlet density levels in Oregon counties were associated with increased alcohol and marijuana co-use and beliefs supportive of alcohol and marijuana use among adolescents. We conducted secondary analyses of biennial data collected from 11th graders who participated in the Student Wellness Survey (SWS) in 36 Oregon counties from 2010 to 2018 ( = 71,870). Multi-level logistic regression analyses assessed changes in past-30-day co-use of alcohol and marijuana, and alcohol- and marijuana-related beliefs after RML in counties with low, medium, and high densities of licensed recreational marijuana and alcohol retail outlets.
