Measurement of cigarette relighting: A common but understudied behavior

OBJECTIVE

Relighting, i.e., extinguishing, saving, and later relighting and smoking unfinished cigarettes, appears prevalent, may be associated with nicotine dependence and negative health outcomes, yet is poorly understood. We estimate the prevalence, frequency, correlates of, and reasons for, cigarette relighting.

METHODS

Survey respondents (n=676) were 18-45-year-old US-based Amazon Mechanical Turk (MTurk) participants who smoked cigarettes every/some days. Items assessed frequency of and reasons for relighting. Reported smoking sessions per day were compared to calculations based on reported cigarettes per day (CPD) and relighting frequency.

RESULTS

Seventy-two percent of those who smoked reported relighting cigarettes. Reasons included not having time to finish (77%), not feeling like finishing (75%), saving money or avoiding wasting (70%), and making cigarettes last longer (59%). Nearly half (44%) relight to cut down and 34% to reduce harm. Hispanic (OR=1.73, CI:1.03-2.91) and non-Hispanic Black respondents (OR= 2.23, CI:1.20-4.10) had higher odds of relighting than others, as did those who smoke within 30minutes of waking (OR=2.45, CI:1.33-4.52) or wake up at night to smoke (OR=2.40, CI:1.68-3.44) (all ps <0.05). Respondents demonstrated low consistency in reporting the number of times they smoke (first-lit and relit) compared to calculations based on CPD and relighting frequency.

CONCLUSIONS

Relighting is associated with race, ethnicity, nicotine dependence, and is often done to save money, cut down smoking, and reduce harm. Among those who relight, "smoking session" frequency seemed to be underestimated. Single item smoking frequency measures may not be ideal for individuals who smoke and relight.

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.

Psychosocial factors influencing smoking relapse among youth experiencing homelessness: A qualitative study

OBJECTIVES

In the United States, up to 70% of youth experiencing homelessness smoke cigarettes. Many are interested in quitting; however, little is known about psychosocial factors influencing smoking relapse in this population. This study, part of a larger project to develop an optimized smoking cessation intervention for youth experiencing homelessness, aimed to describe how psychosocial factors influence smoking relapse in this group.

METHODS

This study describes the smoking relapse experiences of 26 youth tobacco users, aged 14-24 years, who were recruited from a homeless drop-in center in Ohio. We conducted semi-structured interviews to understand how stress, opportunity, and coping contribute to smoking relapse.

RESULTS

Five themes emerged from the data: (1) smoking as a lapse in emotional self-regulation in response to stress; (2) smoking as active emotional self-regulation in response to stress; (3) social opportunities facilitate smoking in the context of emotion-focused stress coping; (4) problem-focused stress coping; and (5) opportunity facilitates smoking relapse.

CONCLUSIONS

Stress was a primary driver of smoking relapse among youth experiencing homelessness, yet social and environmental opportunities to smoke also precipitated relapse. Interventions to improve abstinence among this population should target foundational stressors, coping skills, social supports, and nicotine dependence.

Mental health correlates of quitting cigarette smoking in youth experiencing homelessness

Smoking prevalence among youth experiencing homelessness (YEH) is three times higher than smoking prevalence among the general population. Many YEH who smoke are interested in quitting smoking, but also report smoking to cope with mental health symptoms. Research on factors that facilitate or impede successful smoking cessation among YEH is limited. This study examined mental health correlates (i.e., anxiety and depression symptoms) of quitting-related factors (i.e., quit attempts, perceived barriers to quitting) and whether smoking to cope moderates these relationships among this vulnerable population. The sample consisted of 77 YEH cigarette smokers between the ages of 18-25 who were interested in quitting. Participants completed a survey assessing various behavioral and cognitive factors related to tobacco use. Analyzing two separate models, hierarchical negative binomial and hierarchical linear regression were used to examine hypothesized correlates of the number of past year quit attempts and perceived barriers to quitting. Smoking to cope moderated the relationships of depression with past year quit attempts and perceived barriers to quitting. Those high in depression and smoking to cope had the fewest number of quit attempts and reported the greatest perceived barriers. Anxiety symptoms were not significantly associated with quit attempts or perceived barriers. Smoking cessation interventions that address using smoking to cope with mental health symptoms may be important for YEH with depression.

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

BACKGROUND

Cigarette smoking is three times more prevalent among youth experiencing homelessness compared with the general population. Co-use of tobacco and marijuana is also common. The aim of this study is to characterize tobacco and marijuana use among youth experiencing homelessness who use combustible tobacco in a Midwestern city to inform smoking cessation intervention.

METHODS

This study included 96 youth (ages 14-24 years; 52% male, 39% female, 5% transgender/non-binary) attending a homeless drop-in center who had used at least one combustible tobacco product in the past week. We assessed past-month use of tobacco products and marijuana, other product use characteristics (e.g., frequency, brand and flavor), and psychosocial predictors of more frequent (i.e., daily) use of combustible tobacco and marijuana.

RESULTS

Most youth experiencing homelessness with past-week combustible tobacco use had used cigarettes (n = 85, 88.5%), cigars (n = 89, 92.7%), and marijuana (n = 82, 85.4%) in the past month. One-third (n = 34) used electronic vapor products (EVPs), 19.8% (n = 19) smoked hookah, and 11.5% (n = 11) used smokeless tobacco (ST). Most marijuana users co-administered with tobacco (n = 67, 69.8%). Daily combustible tobacco smoking was associated with having a child and smoking out of boredom/habit. Daily marijuana use was associated with using substances to cope with one's housing situation. Newport (n = 66, 72.5%) and Black & Mild (n = 48, 51.1%) were the most popular brands of cigarettes and cigars among ever users. Most non-combustible tobacco ever users reported not having a usual brand (EVPs: n = 51, 73.9%; ST: n = 16, 57.1%). Cigar smokers reported the most varied selection of flavors.

CONCLUSIONS

Young combustible tobacco users experiencing homelessness engage in high-risk use patterns, including poly-tobacco use, co-use of tobacco with marijuana, and frequent combustible product use. Interventions that consider the full context of tobacco and marijuana use are needed to support smoking cessation in this population.

"I smoked that cigarette, and it calmed me down": A qualitative analysis of intrapersonal, social, and environmental factors influencing decisions to smoke among youth experiencing homelessness

INTRODUCTION

Approximately 70% of youth experiencing homelessness smoke cigarettes; many try to quit and are interested in formal smoking cessation programs. The purpose of this study was to describe the intrapersonal, social, and environmental contexts associated with the most recent smoking experience among youth experiencing homelessness and (2) identify differences in contextual factors by age and willingness to quit.

METHODS

Thirty-six youth experiencing homelessness aged 14-24 years and who reported current smoking were recruited from a drop-in center in a Midwestern city. Semi-structured in-person interviews were analyzed to understand smoking behaviors.

RESULTS

Two-thirds of participants reported stress and nicotine dependence as primary reasons for smoking, and older youth (aged 18-24 years) reported smoking to de-escalate negative emotions associated with stressful events. For 25% of participants, and especially older youth, smoking was described as part of a routine. Over 80% of participants smoked outside at the homeless drop-in center or the places they lived. Social prompts from drop-in center peers regularly preempted smoking. Younger youth (aged 14-17 years) reported smoking socially while older youth were more likely to smoke alone.

CONCLUSIONS

For youth experiencing homelessness, smoking is integrated into daily life and is often used to manage stress associated with homelessness and engage socially with homeless peers. Multicomponent interventions to reduce structural stressors specific to homelessness, change social smoking norms (environmental and social context), and address stress management and nicotine dependence (intrapersonal context) are needed to support smoking cessation among youth experiencing homelessness.

IMPLICATIONS

Youth experiencing homelessness overwhelmingly described how daily stressors associated with homelessness and nicotine dependence preceded recent smoking. Older youth (aged 18-24 years) also reported smoking as "routine", which likely underscores nicotine dependence in this group. Younger youth (aged 14-17 years) described social smoking. Researchers must develop optimized multilevel interventions to support youth experiencing homelessness who want to quit smoking. Interventions directly targeting social determinants of stress (e.g., poverty, housing instability, food insecurity) and linkages to supportive services are needed. Complementary strategies to address stress coping and nicotine dependence (intrapersonal context) and social smoking norms (social and environmental context) are also necessitated.

Substance Use and Mental Health Outcomes from a Text Messaging-Based Intervention for Smoking Cessation Among Young People Experiencing Homelessness

INTRODUCTION

Cigarette smoking and associated high-risk behaviors are prevalent among youth experiencing homelessness (YEH), making appropriately tailored interventions targeting smoking behavior important for this group. We pilot tested a brief text-messaging intervention (TMI) as an adjunct to standard care for YEH who smoke and found promising preliminary effects of the intervention on smoking cessation. The purpose of the present study was to test the TMI's effect on the secondary outcomes of other substance use (including use of other tobacco/nicotine devices) and mental health symptoms.

METHODS

A total of 77 participants completed the pilot randomized controlled trial, with 40 receiving the TMI (174 automated text messages plus a group smoking counseling session and provision of nicotine patches). They completed an assessment at baseline and another three months later that evaluated use of other tobacco/nicotine devices, alcohol, marijuana, and anxiety and depression symptoms.

RESULTS

We found that the TMI helped to reduce secondary substance use behaviors and mental health symptoms among the participants; mainly there were medium effects of the intervention on changes in other tobacco/nicotine use, drinking, and anxiety and depression symptoms. The intervention did not have an effect on number of marijuana use days in the past month; however, past 30-day marijuana users who received the intervention benefited by reducing the number of times they used marijuana per day.

CONCLUSIONS

In addition to helping reduce cigarette smoking, we found that a TMI for YEH was helpful in improving secondary outcomes, suggesting the promise of the TMI on benefiting YEH even beyond targeted smoking behavior.

IMPLICATIONS

This pilot study demonstrates that by targeting cigarette smoking using a text message-based intervention among youth experiencing homelessness, effects may be seen in other areas of functioning such as other substance use and mental health.

Rodent host population dynamics drive zoonotic Lyme Borreliosis and Orthohantavirus infections in humans in Northern Europe

Zoonotic diseases, caused by pathogens transmitted between other vertebrate animals and humans, pose a major risk to human health. Rodents are important reservoir hosts for many zoonotic pathogens, and rodent population dynamics affect the infection dynamics of rodent-borne diseases, such as diseases caused by hantaviruses. However, the role of rodent population dynamics in determining the infection dynamics of rodent-associated tick-borne diseases, such as Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato bacteria, have gained limited attention in Northern Europe, despite the multiannual abundance fluctuations, the so-called vole cycles, that characterise rodent population dynamics in the region. Here, we quantify the associations between rodent abundance and LB human cases and Puumala Orthohantavirus (PUUV) infections by using two time series (25-year and 9-year) in Finland. Both bank vole (Myodes glareolus) abundance as well as LB and PUUV infection incidence in humans showed approximately 3-year cycles. Without vector transmitted PUUV infections followed the bank vole host abundance fluctuations with two-month time lag, whereas tick-transmitted LB was associated with bank vole abundance ca. 12 and 24 months earlier. However, the strength of association between LB incidence and bank vole abundance ca. 12 months before varied over the study years. This study highlights that the human risk to acquire rodent-borne pathogens, as well as rodent-associated tick-borne pathogens is associated with the vole cycles in Northern Fennoscandia, yet with complex time lags.

Pilot Randomized Clinical Trial of a Text Messaging-Based Intervention for Smoking Cessation Among Young People Experiencing Homelessness

INTRODUCTION

Smoking rates are alarmingly high among young people experiencing homelessness (YEH), yet there are no evidence-based cessation programs for this population. This paper presents results from a pilot evaluation of a text messaging-based smoking cessation treatment, as an adjunct to brief group cessation counseling, to improve abstinence rates among 18-25 year old smokers experiencing homelessness. The goal of this study was to estimate effect sizes for a larger trial and it was not powered to detect group differences.

METHODS

YEH smokers who had a working cell phone with them at recruitment were randomized to receive a group counseling session, nicotine patches, and written material on quitting (n=37) or a similar program that also included a 6-week automated text messaging intervention (TMI) to provide ongoing support for quitting (n=40). Smoking outcomes were evaluated through a 90-day follow-up.

RESULTS

7-day point prevalence abstinence at 90-day follow-up was higher in the TMI condition than standard condition (17.50% vs. 8.11%, respectively; Cohen's h=.37); however, the 90-day continuous abstinence rate was not statistically different from zero in either condition. Reductions in the number of days smoked in the past 30 days from baseline to follow-up were greater in the TMI condition than the standard condition (-14.24 vs. -8.62, respectively; Cohen's d=.49).

CONCLUSIONS

Adding a 6-week TMI support to a brief group counseling and pharmacotherapy protocol holds promise for smoking reduction and abstinence among YEH smokers. Results indicate that further development and evaluation of the TMI in this population is warranted.

IMPLICATIONS

This is the first study to evaluate the feasibility of using a text messaging-based intervention (TMI) for behavior change with 18-25 year olds experiencing homelessness, and more specifically, the first to test a TMI to provide ongoing support for smoking cessation. Small to medium effect sizes for the TMI are promising in terms of implementing a TMI using participants' own cell phones, as well as the efficacy of this approach as an adjunct to standard care (brief group counseling and pharmacotherapy) for smoking cessation among young people experiencing homelessness.

Text Messaging Intervention for Young Smokers Experiencing Homelessness: Lessons Learned From a Randomized Controlled Trial

BACKGROUND

Smoking rates are significantly higher among young people experiencing homelessness than in the general population. Despite a willingness to quit, homeless youth have little success in doing so on their own, and existing cessation resources tailored to this population are lacking. Homeless youth generally enjoy the camaraderie and peer support that group-based programs offer, but continuous in-person support during a quit attempt can be prohibitively expensive.

OBJECTIVE

This study aimed to assess the feasibility and acceptability of an automated text messaging intervention (TMI) as an adjunct to group-based cessation counseling and provision of nicotine patches to help homeless youth quit smoking. This paper outlines the lessons learned from the implementation of the TMI intervention.

METHODS

Homeless youth smokers aged 18 to 25 years who were interested in quitting (n=77) were recruited from drop-in centers serving homeless youth in the Los Angeles area. In this pilot randomized controlled trial, all participants received a group-based cessation counseling session and nicotine patches, with 52% (40/77) randomly assigned to receive 6 weeks of text messages to provide additional support for their quit attempt. Participants received text messages on their own phone rather than receiving a study-issued phone for the TMI. We analyzed baseline and follow-up survey data as well as back-end data from the messaging platform to gauge the acceptability and feasibility of the TMI among the 40 participants who received it.

RESULTS

Participants had widespread (smart)phone ownership-16.4% (36/219) were ineligible for study participation because they did not have a phone that could receive text messages. Participants experienced interruptions in their phone use (eg, 44% [16/36] changed phone numbers during the follow-up period) but reported being able to receive the majority of messages. These survey results were corroborated by back-end data (from the program used to administer the TMI) showing a message delivery rate of about 95%. Participant feedback points to the importance of carefully crafting text messages, which led to high (typically above 70%) approval of most text messaging components of the intervention. Qualitative feedback indicated that participants enjoyed the group counseling session that preceded the TMI and suggested including more such group elements into the intervention.

CONCLUSIONS

The TMI was well accepted and feasible to support smoking cessation among homeless youth. Given high rates of smartphone ownership, the next generation of phone-based smoking cessation interventions for this population should consider using approaches beyond text messages and focus on finding ways to develop effective approaches to include group interaction using remote implementation. Given overall resource constraints and in particular the exigencies of the currently ongoing COVID-19 epidemic, phone-based interventions are a promising approach to support homeless youth, a population urgently in need of effective smoking cessation interventions.

Interventions to reduce tobacco use in people experiencing homelessness

BACKGROUND

Populations experiencing homelessness have high rates of tobacco use and experience substantial barriers to cessation. Tobacco-caused conditions are among the leading causes of morbidity and mortality among people experiencing homelessness, highlighting an urgent need for interventions to reduce the burden of tobacco use in this population.

OBJECTIVES

To assess whether interventions designed to improve access to tobacco cessation interventions for adults experiencing homelessness lead to increased numbers engaging in or receiving treatment, and whether interventions designed to help adults experiencing homelessness to quit tobacco lead to increased tobacco abstinence. To also assess whether tobacco cessation interventions for adults experiencing homelessness affect substance use and mental health.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register, MEDLINE, Embase and PsycINFO for studies using the terms: un-housed*, homeless*, housing instability, smoking cessation, tobacco use disorder, smokeless tobacco. We also searched trial registries to identify unpublished studies. Date of the most recent search: 06 January 2020.

SELECTION CRITERIA

We included randomized controlled trials that recruited people experiencing homelessness who used tobacco, and investigated interventions focused on the following: 1) improving access to relevant support services; 2) increasing motivation to quit tobacco use; 3) helping people to achieve abstinence, including but not limited to behavioral support, tobacco cessation pharmacotherapies, contingency management, and text- or app-based interventions; or 4) encouraging transitions to long-term nicotine use that did not involve tobacco. Eligible comparators included no intervention, usual care (as defined by the studies), or another form of active intervention.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane methods. Tobacco cessation was measured at the longest time point for each study, on an intention-to-treat basis, using the most rigorous definition available. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) for smoking cessation for each study where possible. We grouped eligible studies according to the type of comparison (contingent reinforcement in addition to usual smoking cessation care; more versus less intensive smoking cessation interventions; and multi-issue support versus smoking cessation support only), and carried out meta-analyses where appropriate, using a Mantel-Haenszel random-effects model. We also extracted data on quit attempts, effects on mental and substance-use severity, and meta-analyzed these outcomes where sufficient data were available.

MAIN RESULTS

We identified 10 studies involving 1634 participants who smoked combustible tobacco at enrolment. One of the studies was ongoing. Most of the trials included participants who were recruited from community-based sites such as shelters, and three included participants who were recruited from clinics. We judged three studies to be at high risk of bias in one or more domains. We identified low-certainty evidence, limited by imprecision, that contingent reinforcement (rewards for successful smoking cessation) plus usual smoking cessation care was not more effective than usual care alone in promoting abstinence (RR 0.67, 95% CI 0.16 to 2.77; 1 trial, 70 participants). We identified very low-certainty evidence, limited by risk of bias and imprecision, that more intensive behavioral smoking cessation support was more effective than brief intervention in promoting abstinence at six-month follow-up (RR 1.64, 95% CI 1.01 to 2.69; 3 trials, 657 participants; I² = 0%). There was low-certainty evidence, limited by bias and imprecision, that multi-issue support (cessation support that also encompassed help to deal with other challenges or addictions) was not superior to targeted smoking cessation support in promoting abstinence (RR 0.95, 95% CI 0.35 to 2.61; 2 trials, 146 participants; I² = 25%). More data on these types of interventions are likely to change our interpretation of these data. Single studies that examined the effects of text-messaging support, e-cigarettes, or cognitive behavioral therapy for smoking cessation provided inconclusive results. Data on secondary outcomes, including mental health and substance use severity, were too sparse to draw any meaningful conclusions on whether there were clinically-relevant differences. We did not identify any studies that explicitly assessed interventions to increase access to tobacco cessation care; we were therefore unable to assess our secondary outcome 'number of participants receiving treatment'.

AUTHORS' CONCLUSIONS

There is insufficient evidence to assess the effects of any tobacco cessation interventions specifically in people experiencing homelessness. Although there was some evidence to suggest a modest benefit of more intensive behavioral smoking cessation interventions when compared to less intensive interventions, our certainty in this evidence was very low, meaning that further research could either strengthen or weaken this effect. There is insufficient evidence to assess whether the provision of tobacco cessation support and its effects on quit attempts has any effect on the mental health or other substance-use outcomes of people experiencing homelessness. Although there is no reason to believe that standard tobacco cessation treatments work any differently in people experiencing homelessness than in the general population, these findings highlight a need for high-quality studies that address additional ways to engage and support people experiencing homelessness, in the context of the daily challenges they face. These studies should have adequate power and put effort into retaining participants for long-term follow-up of at least six months. Studies should also explore interventions that increase access to cessation services, and address the social and environmental influences of tobacco use among people experiencing homelessness. Finally, studies should explore the impact of tobacco cessation on mental health and substance-use outcomes.

Smoking cessation methods among homeless youth in a Midwestern city

•

More than two-third of homeless youth in this study were willing to quit smoking.

•

Evidence-based treatments were being underutilized by homeless youth in this study.

•

Nicotine replacement therapy was mostly perceived negatively, likely due to misuse.

•

Drop-in centers may be an effective location from which to offer cessation services.

Introduction

Nearly three times as many homeless youth smoke cigarettes in the United States (US) compared to the general population of youth. Few studies have focused on how to help homeless youth quit smoking. As part of a series of studies to develop a smoking cessation intervention for homeless youth, this study aimed to describe methods used in past quit attempts by homeless youth.

Methods

 Recruited from a drop-in center in the Midwestern US, the analytic sample was comprised of 32 unaccompanied homeless youth aged 14–24 who smoked combustible tobacco at some point in the past week. In-person qualitative interviews were conducted to understand prior quit attempt experiences of homeless youth.

Results

Twenty-two youth (69%) were willing to quit smoking in the next 30 days. Most previous quit attempts were unassisted (78%). Participants frequently reported engaging in distracting behaviors (e.g., video games) or thoughts (e.g., remaining positive). Nicotine replacement therapy (NRT) was another popular method (38%), but with mostly negative reactions. While less common, vaping and use of cannabis to substitute cigarettes was reported in a notable faction of youth (28%), primarily 18–24 years of age.

Conclusions

Youth are primarily engaging in non-evidence-based strategies to quit smoking. Existing evidence-based treatments are often underutilized or not used according to instructions, and youth who do use evidence-based treatments do not find them useful. Future research should explore effective cessation treatment among homeless youth that can ideally be provided at shelters and drop-in centers.

Implications

Existing evidence-based treatments are underutilized by homeless youth in this study. Most homeless youth are willing to quit in the next month and are interested in trying behavioral counseling and monitored use of NRT. Drop-in centers may be an effective location from which to develop and offer targeted smoking cessation interventions for homeless youth.

Motivation to quit cigarettes and alternative tobacco products: prevalence and correlates among youth experiencing homelessness

Use of alternative tobacco products, as well as regular cigarettes, is widespread among unaccompanied youth experiencing homelessness. However, little is known about their level of motivation for quitting use of these products, factors associated with motivation to quit, or how these might vary by type of tobacco product. Unaccompanied homeless youth were sampled from 25 street and service sites in Los Angeles County (N = 469). All participants were past month tobacco users who completed a survey on their tobacco-related behaviors and cognitions, including motivation to quit, as well as background characteristics. Among self-reported users of each product, motivation to quit in the next 30 days was highest for regular cigarettes (33%), followed by e-cigarettes/vaporizers (30%), little cigars/cigarillos (25%), cigars (20%), and natural cigarettes (20%). Between 33 and 49% of youth, depending on product, were not thinking about quitting at all. Correlates of lower motivation to quit differed somewhat by product type, with the most consistent being race, more frequent use, lower perceived riskiness of the product, and using the product because of its good taste or smell. Results from this study identify a set of psychosocial and behavioral factors, some that are common across tobacco products and others that are product-specific, that may be particularly important to address in efforts to reduce tobacco use among youth experiencing homelessness. Future regulations on the sale of flavored tobacco products may also serve to increase motivation to quit in this population.

A text message intervention for quitting cigarette smoking among young adults experiencing homelessness: study protocol for a pilot randomized controlled trial

BACKGROUND

Cigarette smoking is much more prevalent among young people experiencing homelessness than in the general population of adolescents and young adults. Although many young homeless smokers are motivated to quit, there are no empirically-evaluated smoking cessation programs for this population. It is important that any such program address the factors known to be associated with quitting-related outcomes among homeless young people, to provide ongoing support in a way that accommodates the mobility of this population, and does not rely on scarce service provider resources for its delivery. The objective of this project is to develop and pilot test a text messaging-based intervention (TMI), as an adjunct to brief cessation counseling and provision of nicotine patches, to help homeless young people who want to quit smoking.

METHODS/DESIGN

This pilot study will utilize a cluster cross-over randomized controlled design with up to 80 current smokers who desire to quit and are recruited from three drop-in centers serving young people experiencing homelessness in the Los Angeles area. All participants will be provided with a minimum standard of care: a 30-min group-based smoking cessation counseling session and free nicotine replacement. Half of these smokers will then also receive the TMI, as an adjunct to this standard care, which will provide 6 weeks of ongoing support for quitting. This support includes continued and more intensive education regarding nicotine dependence, quitting smoking, and relapse; does not require additional agency resources; can be available "on demand" to users; and includes features to personalize the quitting experience. This study will investigate whether receiving the TMI adjunct to standard smoking cessation care results in greater reductions in cigarette smoking compared to standard care alone over a 3-month period.

DISCUSSION

This study has the potential to address an important gap in the clinical research literature on cigarette smoking cessation and provide empirical support for using a TMI to provide ongoing assistance and support for quitting among young smokers experiencing homelessness.

Roll-your-own cigarette smoking among youth experiencing homelessness

INTRODUCTION

Roll-your-own (RYO) cigarette smoking is uncommon among young smokers in the U.S. but may be more widespread among those experiencing homelessness as it is a less expensive source of cigarettes. This study examines the prevalence and correlates of RYO use among young cigarette smokers experiencing homelessness.

METHODS

The analytic sample consisted of 433 unaccompanied homeless youth who reported past month use of factory-manufactured cigarettes. Participants were sampled from 25 street and service sites in Los Angeles County, and completed a survey on their tobacco-related behaviors and cognitions.

RESULTS

RYO use was reported by 43% of cigarette smokers. Among those who filled RYOs with tobacco, 87% rolled them with used tobacco (typically mixed with new tobacco). Most RYO smokers reported engaging in high-risk smoking practices, such as smoking discarded cigarettes. Although RYO smokers were more likely than other smokers to perceive RYOs as less risky in general, these groups did not differ in the perceived relative harm, expense, and ease of access of RYOs compared to regular cigarettes. Multivariable analyses indicated that RYO use was associated with older age, less perceived riskiness of RYOs, greater exposure to RYO smokers, and stronger future intentions to smoke.

CONCLUSION

RYOs may encourage continued tobacco use among youth experiencing homelessness and pose additional health risks despite users' beliefs to the contrary. Future research is needed to obtain more detailed information on RYO practices and motivations for use, as well as how to address RYOs in efforts to reduce tobacco use in this population.

Developing a text messaging-based smoking cessation intervention for young smokers experiencing homelessness

Introduction

Cigarette smoking is highly prevalent among young people experiencing homelessness, and many of these smokers are motivated to quit. However, there is a lack of readily available cessation services for this population, which is highly mobile and can be challenging to engage in services.

Aims

We describe the development of a smoking cessation text messaging intervention (TMI) for homeless youth who are interested in quitting smoking.

Methods

Participants were 18–25 years old and recruited from drop-in centers serving homeless youth. Three focus groups (N = 18) were conducted with smokers to refine the TMI content, and a separate sample of smokers (N = 8) provided feedback on the TMI after using it for 1 week. Survey data assessed the TMI's acceptability and feasibility.

Results

Participants generally rated the TMI as helpful and relevant, and nearly all had cell phone plans that included unlimited texting and were able to view TMI content with few difficulties. Qualitative feedback on strengths/limitations of the TMI in terms of content, tone, and delivery parameters was used to finalize the TMI for a future evaluation.

Conclusions

Results suggest that a TMI is a feasible and acceptable option for young people experiencing homelessness who are interested in quitting smoking.

Perceived Need and Receipt of Behavioral Health Services at Drop-In Centers among Homeless Youth

OBJECTIVE

Homeless youth are a population in need of housing assistance and case management, as well as services to address behavioral health problems. This study examines youth's perceived need for and receipt of services through drop-in centers.

DATA SOURCE

Surveys of 273 homeless youth.

STUDY DESIGN

Cross-sectional.

EXTRACTION METHODS

Descriptive analyses with bivariate and multivariable regression models.

PRINCIPAL FINDINGS

About one-third to half of the sample met criteria for behavioral health problems, yet half or less of those meeting criteria reported a need for services targeting the problems. Most youth who perceived a need for services received relevant services through a drop-in center, with the exception of care for substance use problems. Youth with behavioral health problems were more likely to perceive a need for services related to housing and case management than those addressing behavioral health problems more directly. Multivariable regression analyses indicated that the factors most strongly associated with perceived need for services were not behavioral health problems, but rather race/ethnicity, traveler status, trouble meeting basic needs, delinquency, abuse/victimization experiences, and trading sex.

CONCLUSIONS

Findings can help to develop outreach and intervention efforts to reach homeless youth and help promote the use of behavioral health services.

Evaluation of Tobacco Control Policies in San Francisco Homeless Housing Programs

BACKGROUND

The 2014 Surgeon General's Report noted that high smoking rates in vulnerable populations such as the homeless have been a persistent public health problem; smoking prevalence among individuals experiencing homelessness exceeds 70%. Historically, service providers for the homeless have not enacted comprehensive tobacco control policies.

METHOD

We conducted a qualitative study of homeless housing programs in San Francisco. Administrators representing 9 of the city's 11 homeless service agencies were interviewed to assess institutional smoking-related policies and cessation programs and perceived barriers and receptivity to instituting tobacco control interventions.

RESULTS

Respondents indicated that although most programs had adopted smoke-free grounds and some had eliminated evidence of staff smoking, the smoking status of clients was assessed only when required by funders. None of the programs offered smoking cessation interventions. Most administrators were receptive to adopting policies that would promote a tobacco-free culture; however, they noted that their clients had unique challenges that made traditional smoking cessation programs unfeasible.

CONCLUSIONS

Homeless housing programs in San Francisco have not yet adopted a tobacco-free culture. Existing policies were created in response to external mandates, and smoking cessation programs may need to be modified in order to effectively reach clients.

Racial Differences in Cigarette Smoking Among Homeless Youth

INTRODUCTION

Several studies have reported pronounced racial/ethnic differences in smoking behavior among homeless youth. Better understanding the factors underlying racial/ethnic differences in daily smoking among homeless youth may help inform programs to reduce smoking in this population.

METHODS

Data come from a probability sample of homeless youth in Los Angeles County collected between 2008 and 2009. The sample includes 116 African American, 99 Hispanic, and 119 White youth with ages ranging from 13 to 24 years. Chi-square tests were used to test the differences in daily smoking among African American, Hispanic, and White youth. Propensity score and doubly robust methods were used to produce a less biased estimate of the association between daily smoking and race/ethnicity after having removed the effect of potential confounders.

RESULTS

The daily smoking rate for White youth was 70.1%, more than 31 percentage points than the rates for either African American or Hispanic youth. Propensity score analysis revealed that the majority of the racial/ethnic differences in smoking rates could be explained by differences in homelessness severity, although background characteristics and comorbidity were relevant as well.

CONCLUSIONS

As programs are developed to reduce smoking among homeless youth, results suggest that additional outreach may be needed to engage White youth in services. Also, smoking prevention programs may benefit from incorporating a social network-based approach that assists youth in fostering relationships with lower-risk peers, as well as addressing other forms of substance use. Incorporating these elements may help reduce the large racial/ethnic disparities in daily smoking among homeless youth.

IMPLICATIONS

This report extends the small existing literature on racial/ethnic differences in smoking among homeless youth in two important respects. First, it confirms differences in daily smoking, an important indicator of dependence, across racial/ethnic groups. Second, it seeks to understand the extent to which differences in smoking can be explained by demographic characteristics (other than race/ethnicity), background factors, homelessness severity, and comorbidity characteristics known to be associated with substance use among homeless youth.

Sniping and other high-risk smoking practices among homeless youth

BACKGROUND

This study of homeless youth uses quantitative data to estimate the prevalence of high-risk smoking practices (obtaining or using cigarettes in a way that increase exposure to toxins and/or susceptibility to infectious diseases) and identify characteristics associated in particular with sniping (smoking discarded cigarettes), and qualitative data to describe why and how homeless youth engage in sniping.

METHODS

A probability sample of 292 homeless youth smokers in Los Angeles County completed a self-administered survey, and a separate convenience sample of 27 homeless youth who were lifetime smokers participated in focus groups. Survey participants reported on background characteristics, smoking cognitions, and high-risk smoking practices. Focus group participants described how they obtained cigarettes and responses relevant to sniping were coded.

RESULTS

Survey results indicated that nearly all youth engaged in at least one high-risk smoking practice, with three-quarters having sniped cigarettes in the past 30 days. Sniping was more frequent among youth with less negative smoking attitudes (b=-0.29, 95% CI=-0.55 to -0.04, p=0.02), greater nicotine dependence (b=0.11, 95% CI=0.00 to 0.23, p=0.046), lower income (b=-0.05, 95% CI=-0.09 to -0.01, p=0.02), and more severe drug abuse (b=0.15, 95% CI=0.04, 0.26, p=0.01). Focus groups data indicated that youth snipe because it provides cheap and easy access to tobacco, and use specific strategies to mitigate the perceived health risks of sniping.

CONCLUSIONS

Sniping and other high-risk smoking practices deserve further attention among homeless youth, particularly those already facing greater health threats due to factors such as nicotine dependence, lower income, and drug abuse.
