Characterizing tobacco and marijuana use among youth combustible tobacco users experiencing homelessness - considering product type, brand, flavor, frequency, and higher-risk use patterns and predictors

Substance use typologies among young people experiencing homelessness in seven cities across the United States: A latent class analysis

BACKGROUND

Substance use and other health-risk risk factors, including mental health, trauma, and sexual-risk behaviors, often co-occur among youth experiencing homelessness (YEH). The present study aimed to identify subgroups of YEH based on polysubstance use and the linkages to sociodemographic and health-risk characteristics.

METHODS

From June 2016 to July 2017, 1,426 YEH (aged 18-26 years) were recruited from seven cities (Houston, Los Angeles, Denver, Phoenix, New York City, St. Louis, San Jose). Participants provided information via a self-administered electronic survey on substance use, mental health, trauma, sexual risk behaviors, and sociodemographic characteristics. The majority of YEH identified as Black (37.3%), cisgender (92.8%), and heterosexual (69.2%). On average, YEH were 20.9 years (SD = 2.1). This study employed latent class analysis (LCA) to identify subgroups of YEH according to their substance use. Multinomial logistic regression analyses were conducted to identify sociodemographic and health-risk characteristics associated with class-membership.

RESULTS

Four latent classes of YEH substance use were identified: (1) high polysubstance use; (2) moderate stimulant and high marijuana, alcohol, and prescription drug use; (3) high marijuana, alcohol, and prescription drug use; (4) low/moderate marijuana and alcohol use. Multinomial logistic regression models indicated that geographic location, gender, race/ethnicity, mental health, trauma history, and sexual risk behaviors were significant correlates of substance use class membership among YEH.

CONCLUSIONS

These findings offer important implications for the prevention and treatment of substance use among YEH. Screening protocols should consider co-occurring risk factors such as traumatic experiences, sexual risk behaviors, and mental health history as indicators of polysubstance use.

Identifying Novel Motivation Phase-Specific Cessation Targets for Youth Experiencing Homelessness in the United States

INTRODUCTION

Of youth experiencing homelessness (YEH; 14-24 years old), 70%+ smoke combustible, commercial tobacco. Though many have tried to quit, most use ineffective methods. Drop-in centers for YEH are opportune places to link YEH to evidence-based treatment. Using the Phase-Based Model (PBM) for Cessation Research, the aim of this study was to identify "Motivation" phase-specific challenges impacting YEH's willingness to make a quit attempt-the goal of this cessation phase.

AIMS AND METHODS

Surveys were interview administered with 96 past-week combusted tobacco users accessing drop-in services. Regression models were fit to confirm hypothesized challenges impacting YEH's willingness to quit.

RESULTS

Moderate nicotine dependence was noted-a key Motivation phase cessation mechanism targeted-and was associated with population challenges including, but not limited to, replacing food with tobacco, accidental oxygen-deprivation events, and smoking to socialize. While 67.1% of participants made a past-year quit attempt, 45.8% expressed 30-day quit interest. Dimensions of coping with housing were associated with quit attempts and quit interest. Quit attempts were also associated with nicotine dependence, working, and smoking to socialize. Whereas, quit interest was associated with less endorsement of smoking to regulate affect and more endorsement to avoid danger.

CONCLUSIONS

Though common challenges targeted in Motivation phase cessation exist among YEH, other challenges may also need to be addressed to promote quitting.

IMPLICATIONS

Future research in optimizing evidence-based cessation access for YEH through drop-in centers may consider addressing the challenges of housing, food security, social context, violence, and neurotrauma sequela to bolster YEH willingness to make a quit attempt.

Smartphone Apps Targeting Youth Tobacco Use Prevention and Cessation: An Assessment of Credibility and Quality

Purpose of Review

The goals of this study were to identify smartphone apps targeting youth tobacco use prevention and/or cessation discussed in the academic literature and/or available in the Apple App Store and to review and rate the credibility of the apps. We took a multiphase approach in a non-systematic review that involved conducting parallel literature and App Store searches, screening the returned literature and apps for inclusion, characterizing the studies and apps, and evaluating app quality using a standardized rating scale.

Recent Findings

The negative consequences of youth tobacco use initiation are profound and far-reaching. Half of the youth who use nicotine want to quit, but quit rates are low. The integration of smartphone apps shows promise in complementing and enhancing evidence-based youth tobacco prevention and treatment methods.

Summary

Consistent with prior reviews, we identified a disconnect between apps that are readily accessible and those that have an evidence base, and many popular apps received low quality scores. Findings suggest a need for better integration between evidence-based and popular, available apps targeting youth tobacco use.

Housing status as a social determinant of disparities in adolescent smoking, vaping, and dual use of cigarettes and e-cigarettes

Little is known about how various housing situations among adolescents may be associated with differential patterns of smoking and vaping-information with practical relevance for tobacco prevention and control efforts. We analyzed disparities by housing status in past 30-day smoking, vaping, and dual use of cigarettes and e-cigarettes/vape products among adolescents participating in the population-based California Healthy Kids Survey (N = 931,355; 2017-2019). Generalized linear mixed models for a categorical outcome quantified differences in prevalence and adjusted odds ratios (AORs) of smoking only, vaping only, and dual use among adolescents in various housing situations relative to their peers living in a home with one or more parents/guardians or other relatives. Our findings suggest adolescents living in a friend's home; adolescents living in a hotel, motel, shelter, car, campground, or other transitional or temporary housing; and adolescents living in a foster home, group care, or waiting placement evidenced pronounced disparities in past 30-day smoking only (AORs: 3.16-3.40, ps < 0.0001) and dual use of cigarettes and e-cigarettes/other nicotine vape products (AOR: 3.73-5.83, ps < 0.0001) relative to their peers living in a home with one or more parents/guardians or other relatives. Vaping only disparities, although significant, were relatively smaller (AORs: 1.53-1.88, ps < 0.0001). These findings emphasize housing as a social determinant of smoking, vaping, and dual use disparities among adolescents and have implications for multilevel preventive intervention development.
