Differential Effects of Neighborhood Type on Adolescent Alcohol Use in New Zealand

Does geographic availability of alcohol influence drinking in adolescents? A systematic review of literature associations

BACKGROUND

The role of alcohol geographic availability in influencing adolescent drinking has been debated. However, clear literature consensus has not been reached.

OBJECTIVE

To provide a systematic review of the associations between geographic availability of alcohol outlets measured through different methodologies and drinking outcomes in adolescents.

METHODS

We conducted a systematic search (PubMed/SCOPUS/Web of Science) for articles exploring associations between alcohol availability and adolescent drinking before 2023. Original articles written in English that evaluated adolescent populations (10-19 years old), included at least one quantitative alcohol consumption outcome and its relationship with geographic availability of alcohol, and declared no conflicts of interest were selected for the review. A quality assessment of the selected articles was made using the Newcastle-Ottawa Scale and descriptive analyses were carried out to summarize results.

RESULTS

Thirty-one articles were reviewed (19 cross-sectional and 12 longitudinal studies), which included a total of 507336 participants. Alcohol availability was positively related to drinking prevalence and risky patterns in 53.3% and 60.5% of associations, respectively. Individual-level covariates, the type of alcohol outlets measured and the different methodological approaches to measure outlet density were related to differences in the direction and magnitude of these associations.

CONCLUSION

Just over half of the studies in this review demonstrate a positive association between alcohol availability and adolescent alcohol consumption with no negative associations reported. The review highlights the mix of methodological approaches that are used, which made it difficult to conduct joint analyses. Additional research is needed to explore the appropriateness, effectiveness and reliability of these methods within various contexts.

The potential adverse effects of minors' exposure to alcohol-related stimuli via licenced venues: A narrative review

ISSUES

Young people are particularly impressionable when it comes to forming expectations and attitudes around alcohol consumption. Any stimuli that normalise and foster positive expectations around alcohol use may increase the risk of underage alcohol consumption. Alcohol venues that market themselves as being appropriate 'family friendly' establishments for children risk exposing minors to environments that are saturated with alcohol-related stimuli. However, research examining how exposure to licenced venues affects underage people is very limited. The aim of this narrative review was to identify and synthesise relevant evidence to better understand how attending these venues might affect minors.

APPROACH

A narrative review of research published between January 2016 and November 2022 was conducted to investigate the potential effects on underage people of exposure to licenced venues and stimuli encountered in/around these venues. Examined stimuli included alcohol advertising, people consuming alcohol and alcohol outlets.

KEY FINDINGS

The reviewed literature indicates that the risk of alcohol-related harm among minors is likely to increase with greater exposure to alcohol venues due to the associated exposure to alcohol advertising, exposure to others consuming alcohol and higher outlet density. In combination, these factors are likely to normalise alcohol consumption for minors and create positive alcohol expectancies.

IMPLICATIONS AND CONCLUSION

Venues serving alcohol should be discouraged from targeting families and parents should be warned about the risks associated with taking minors to venues where alcohol is sold and consumed.

Finite mixture models in neighbourhoods-to-health research: A systematic review

A systematic review was conducted, following PRISMA guidelines, to examine the application of finite mixture models (FMMs) in the study of neighbourhoods and health. Two reviewers screened 814-studies identified through database searches and citation tracking. Data were extracted from 19-studies that met the inclusion criteria, and a risk of bias analysis undertaken. Data were synthesised narratively, with a focus on methodological issues idiosyncratic to FMMs. Motivated by a desire to account for neighbourhood heterogeneity, studies sought to identify meaningful neighbourhood-level typologies that explained the distributional nature of health outcomes. Neighbourhood-centred applications of FMMs were promising but there remains scope for advancement. Research-based recommendations are outlined to strengthen prospective neighbourhood-centred studies applying FMMs.

Leisure activity participation in relation to alcohol purchasing and consumption in adolescence

BACKGROUND

Building upon the socioecological perspective, this study examines prospective associations linking leisure activity participation with alcohol purchasing and consumption in early adolescence.

METHODS

A total of 1763 seventh graders (age 12-13 years) were recruited from middle schools in urban Taiwan via multi-stage sampling and followed-up 1.5 years later during ninth grade. Information about leisure activities, covariates (i.e., gender, puberty development, family structure, parental educational attainment, monthly allowance, peer drinking, and childhood alcohol experience), and two outcome variables (i.e., alcohol purchasing and drinking behaviors) was gathered via web-based self-administered questionnaires. Data concerning alcohol outlets and recreational resource for each community district were retrieved from official statistics and commercial sources. Two-level hierarchical generalized linear models were used to evaluate association estimates.

FINDINGS

Five percent of ninth graders ever purchased alcohol and nearly one in seven drank alcohol on three or more occasions (i.e., occasional drinking) in the past year. Sports, unstructured, and organized leisure activities were not linked with illegal alcohol purchasing when community contexts were statistically adjusted; a higher community on-premised alcohol outlet density increased alcohol purchasing by 94% (95% CI = 1.24-3.06). In contrast, unstructured leisure activity participation at 7th grade predicted occasional drinking (adjusted Odds Ratio [aOR] = 5.52; 95% CI = 3.13-9.74). Sports participation was associated with reduced risk of occasional drinking in the communities with high unregulated alcohol outlets (aOR for interaction = 0.58; P < .001).

CONCLUSION

Our research provides insights to differential roles of leisure activity participation in shaping adolescents' commercial alcohol access and occasional drinking. Macro-social contexts should be considered in the efforts to reduce underage drinking problems through leisure activities.
