Little is known about adults in China who drink homemade alcohol, and whether they are at elevated risk of harms relative to those who drink alcohol from commercial sources. Purpose: We describe an...

AIMS To examine whether daily exposure to tobacco outlets within activity spaces is associated with cigarette smoking and with the number of cigarettes smoked by youth that day. DESIGN The study used geographic ecological momentary assessment (GEMA) data that combined daily surveys with ecological momentary assessment of global positioning systems (GPS) using geographic information systems (GIS) to allow for real-time data collection of participants' environments and behaviors. SETTING Eight mid-sized California (USA) city areas. PARTICIPANTS The analytical sample included 1065 days, which were clustered within 100 smoker and non-smoker participants (aged 16-20 years, 60% female). MEASUREMENTS Any cigarette smoking and number of cigarettes smoked on a given day, the number of tobacco outlets within 100 m of activity space polylines each day, the number of minutes participants spent within 100 m of tobacco outlets each day and demographic characteristics (age, sex, race/ethnicity and perceived socio-economic status). FINDINGS Controlling for demographic characteristics, the findings of multi-level mixed effects logistic models were inconclusive, whether or not the number of tobacco outlets within 100 m of youths' activity space polylines or the number of minutes spent within 100 m of tobacco outlets were associated with whether the participant smoked cigarettes on a given day [odds ratio (OR) = 1.05, P = 0.24; OR = 0.99, P = 0.81, respectively]. However, in multi-level zero-inflated negative binomial models, the risk of smoking an additional cigarette on a given day increased with each additional tobacco outlet [incidence rate ratio (IRR) = 1.04, P

Objective: This article provides a systematic review of cross-sectional research examining associations between exposure to alcohol marketing and alcohol use behaviors among adolescents and young adults. Method: Literature searches of eight electronic databases were carried out in February 2017. Searches were not limited by date, language, country, or peer-review status. After abstract and full-text screening for eligibility and study quality, 38 studies that examined the relationship between alcohol marketing and alcohol use behaviors were selected for inclusion. Results: Across alcohol use outcomes, various types of marketing exposure, and different media sources, our findings suggest that cross-sectional evidence indicating a positive relationship between alcohol marketing exposure and alcohol use behaviors among adolescents and young adults was greater than negative or null evidence. In other words, cross-sectional evidence supported that alcohol marketing exposure was associated with young peoples’ alcohol use behaviors. In general, relationships for alcohol promotion (e.g., alcohol-sponsored events) and owning alcohol-related merchandise exposures were more consistently positive than for other advertising exposures. These positive associations were observed across the past four decades, in countries across continents, and with small and large samples. Conclusions: Despite issues of measurement and construct clarity within this body of literature, this review suggests that exposure to alcohol industry marketing may be important for understanding and reducing young peoples’ alcohol use behavior. Future policies aimed at regulating alcohol marketing to a greater extent may have important short- and long-term public health implications for reducing underage or problematic alcohol use among youth.

We investigated the perceived impact of COVID-19 on changes in tobacco and nicotine (NT) use among sexual and gender minority (SGM) young adults. We used a mixed methods approach that included closed- and open-ended survey questions and in-depth interviews. Participants were 53 SGM young adults in California who reported current or past cigarette smoking. Of study participants, 63% (n=33) reported any changes in their NT use, and of those, 60% reported initial increase of NT use. Content analysis of an open-ended survey question revealed three reported reasons for changes in NT use: (1) changes in routine activities (27%), (2) stress (46%), and (3) health (24%). Thematic analysis of qualitative interviews identified several related themes: (1) in discussions of increased NT use, stress and boredom/free time were important aspects of changes to daily routines, (2) fluctuations in NT use behaviors occurred over time, (3) reasons for NT changes were multiple and intertwined, and (4) NT use changes were shaped by experiences related to intersectional forms of structural and social stigmatization. Results reveal the dynamic and complex ways in which participants described their pandemic-related changes in NT use-nuance that is crucial for compassionate and participant-centered approaches to tobacco prevention and cessation.

Adolescent initiation of drinking and intoxication is associated with concurrent and later problems among adolescents. This study explores the mechanisms by which the context of close friendships is important to adolescents' decisions to initiate drinking and heavy alcohol use.In-depth face-to-face qualitative interviews were conducted online with 50 adolescents (12-16 years) who reported lifetime drinking. These semi-structured interviews allowed adolescents to describe their first experiences with drinking, reflecting on their social and environmental contexts, decision-making process, and expectations. We conducted a thematic analysis of the narratives, which revealed the nuances of social relationships and trusting peers and their impacts on alcohol use initiation patterns.In contrast to common perceptions of peer pressure, youth described decision-making about alcohol that was influenced by feelings of safety and security produced by close relationships. Specifically, social relationships, especially the presence of close friends, influenced decisions to initiate alcohol use.Results of this study suggest that close peer relationships enhanced feelings of safety even while engaging in risky behaviors. These results suggest the importance of understanding the complex relationships between social contexts, close friendships, and perceived trust and can inform future research and interventions on alcohol prevention or delayed initiation among adolescents.

Introduction Existing research on youth’s adoption of alternative nicotine delivery systems (ANDS) has focused on identifying pathways of nicotine product use, specifically examining whether vaping encourages progression to smoking. Few studies have considered other pathways of initiation. Qualitative studies suggest that meanings of vaping vary significantly, suggestive of the need for a more nuanced understanding of the role of vaping for youth with different pathways into vaping and smoking. Methods We conducted in-depth qualitative interviews with 49 Californian youth between 15 and 25 years old who reported ever vaping nicotine to gain a deeper understanding of their initiation pathways of vaping and smoking, paying special attention to youth’s experiences and reasons for ANDS initiation and use. Categorizing participants into initiation pathways by self-reported use and age of initiation of ANDS and cigarettes, we then compared the meaning and role of vaping across three distinct pathways of use: (1) smoking to vaping, (2) vaping to smoking, and (3) vaping only. Results The most common pathway reported was smoking to vaping (74%), eight participants began vaping before smoking, and five participants reported only vaping but never smoking. Analysis of participants’ narratives emphasized that youth in our study, regardless of initiation pathway, were generally aware of the health consequences of smoking and negotiated their use of nicotine products considering relative risks. Conclusion Findings from this study suggest that ANDS serve as a transitional tool for youth who are keenly aware of the health consequences of smoking, thus challenging conventional discourses about ANDS as a threat to youth’s health. Implications This qualitative study queries concerns about the potential of alternative nicotine delivery systems (ANDS) to serve as a gateway into cigarette smoking for youth and young adults. Findings suggest that most of the youth participants discussed and considered relative risks in their pathways of initiation, highlighting the need to acknowledge harm reduction in constructing public health messaging and policies for smoking cessation.

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. METHODS: A mixed-methods approach was used to survey and interview adolescents who reported lifetime drinking. Survey responses from 471 participants were analyzed using multilevel multinomial and logistic regressions accounting for nesting of drinking events (i.e., type of initiation) within respondents. A subsample of 50 participants recruited at baseline took part in in-depth interviews that were thematically coded. RESULTS: After controlling for demographics, initiation of HED and intoxication, compared to initiation of a whole drink, were more likely to occur when more close friends are present and when those close friends are also drinking. The likelihood of early initiation of a whole drink and intoxication was also positively associated with being in an outdoor setting. Narratives identified distinct and shared patterns of context characteristics across the types of alcohol initiation. CONCLUSION: The quantitative and qualitative findings revealed several parallels as well as aspects that differ, enriching our understanding of early drinking contexts. Results highlight the importance of considering contextual characteristics by initiation type for prevention efforts.

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. Breath tests were conducted in 2018 and 2019 with samples of pedestrians in the nighttime entertainment districts of Zacatecas and a comparison city (Aguascalientes). Surveys of bar owners/managers and staff, emergency medical personnel (EMP), and police officers were conducted in Zacatecas in 2018 and 2019 to assess awareness and support of the law and possible effects of the law on alcohol-related problems such as violence and injuries. Results Monthly observations indicated that a substantial percentage of bars and off-premises package stores did not comply with the law. Pedestrian breath tests in 2018 and 2019 indicated significant reductions in blood alcohol concentration and heavy drinking among pedestrians in Zacatecas from 11 PM to 2 AM compared to Aguascalientes, but not after 2 AM. Surveys of bar owners/managers indicated that most were aware and supportive of the law. EMP surveys indicated reductions in incidents of physical fighting and drunk or injured customers during the annual September fair in Zacatecas. Conclusions This study suggests that restricting bar opening hours and alcohol sales may not result in full compliance by bars and off-premises stores, but may help to reduce excessive alcohol use and related harms in a middle-income country. A more rigorous evaluation with pre-intervention data is needed, however, to fully address this latter question.

Objective: Evaluations of drink-driving crash interventions and crash burden in middle-income countries often rely on assumptions supported by data from the United States. We described crashes using pooled survey data across 2 Chinese agricultural cities in the 600,000 population range and then assessed comparability of selected crash characteristics to those in the United States.Methods: We conducted household interviews on drinking and related harms with representative samples of 1,500 people aged 18 and over in both Jiangshan and Lanxi, China. Near the end of the survey, 2,962 people responded to questions about motor vehicle crashes during the past year. We report survey data weighted to match the population demographically.Results: Across the 2 cities, 28% of adults were licensed drivers and 24% drove a motorized vehicle. Fifty-three respondents (unweighted) reported that they personally were involved in at least one crash in the past year. Among these, 32% (weighted) were driving a car, truck, or bus; 7.5% were driving a motorcycle; 9.5% were pedalcyclists; 17% were pedestrians; and 34% were passengers. Of the crashes, 42% involved just one motorized vehicle. Most crashes (62%) occurred in broad daylight, followed by at dawn or dusk (19%) and at night (19%). Only 4% were single-vehicle nighttime crashes. Someone was injured or killed in 22% of crashes. Respondents thought it likely that at least one driver was drinking alcohol in 21% of the crashes and thought it unlikely in 51%; the remaining 28% were unsure whether anyone was drinking or refused this question. Alcohol involvement was similar in injury and no-injury crashes. Respondents thought a driver had been drinking in 24% of daytime crashes, 34% of crashes at dawn or dusk, and 36% of nighttime crashes. All 3 crashes involving an alcohol-involved pedestrian or pedalcyclist also included an alcohol-involved driver. Respondents said that 40% of the crashes were reported to the police and 40% were not reported; the remaining 20% of respondents did not know whether anyone reported their crash. Among crashes where reporting status was known, all crashes with injuries were reported.Conclusions: Compared to published data, crash rates are similar among licensed drivers in the United States and these Chinese cities. The percentage of crashes that involved injury did not differ significantly between the 2 countries. Injury crashes were well reported in both. Crashes involving property damage only were significantly less likely to be reported to the police in the Chinese cities. Alcohol involvement rates in crashes were similar. Although our crash sample was small, some crash parameters appear to be transferable between these 2 countries.

Most people who smoke cigarettes begin young. Consequently, public health efforts directed at youth are a priority. The increasing popularity of electronic nicotine delivery systems (ENDS) among youth in the United States has raised concerns in the public health community about the potential of ENDS to renormalize cigarette smoking and perpetuate nicotine addiction, creating dual users who both vape and smoke. Despite limited and inconclusive evidence about dual use for young people, restrictive approaches towards ENDS have shaped tobacco control agendas in the United States. Based on analysis of 26 interviews with young dual users in California, we explored the meanings young people ascribe to their dual using practices and how those meanings relate to the broader tobacco control environment which structures their lives. Results suggest that dual users of ENDS and cigarettes overwhelmingly perceive a utilitarian meaning of dual use and view vaping as a tool for reducing smoking-related harm in the near term and facilitating quitting smoking in the long term. Also, participants’ narratives related to Tobacco 21 laws, which prohibit sales of both ENDS and cigarettes to individuals under 21 years of age, revealed concerns about restrictive policies that limit access to less harmful tobacco products. Results of this study raise important questions about whether we are working towards further reductions in the prevalence of smoking and tobacco-related diseases.

OBJECTIVE. We conducted meta-analyses of studies that investigated the associations between tobacco outlet density around homes and schools and adolescents’ past-month cigarette smoking. DATA SOURCES. Systematic literature searches of eight databases were carried out in February 2017. Searches were not limited by date, language, country, or peer-reviewed status. STUDY SELECTION. After screening for quality, studies that examined the relationship between tobacco outlet density and adolescents’ past-month smoking were selected for inclusion. DATA EXTRACTION. Two investigators screened study abstracts and full texts and independently extracted data. Consensus was reached at each stage. DATA SYNTHESIS. Random effects meta-analyses were conducted on 11 studies that provided 13 effect sizes. Results showed that there was a significant association between tobacco outlet density around homes and adolescents’ past-month smoking behavior with an overall effect size of OR = 1.08 (95% CI = 1.04, 1.13; p
