Smoking reduction among homeless smokers in a randomized controlled trial targeting cessation.

INTRODUCTION: Homeless populations have high rates of smoking and unique barriers to quitting. General cessation strategies have been unsuccessful in this population. Smoking reduction may be a good intermediate goal. We conducted a secondary analysis to identify predictors of smoking reduction in a cohort of homeless smokers enrolled in a 26-week randomized clinical trial (RCT) targeting smoking cessation. METHODS: Data are from an RCT comparing motivational interviewing counseling plus nicotine replacement therapy (NRT) to brief advice to quit (standard care) plus NRT among homeless smokers. Using bivariate analyses and multinomial logistic regression, we compared demographics, health and psychosocial variables, tobacco use, substance use, and NRT adherence among those who reported: quitting; reducing smoking by 50-99%; and not reducing smoking by 50%. RESULTS: Of 324 participants who completed 26-week follow-up, 18.8% and 63.9% self-reported quitting and reducing, respectively. Compared to those who did not reduce smoking, participants reporting reducing indicated higher baseline cigarette use (OR=1.08; CI:1.04-1.12) and menthol use (OR=2.24; CI:1.05-4.77). Compared to participants who reduced, participants reporting quitting were more likely to be male (OR=1.998; CI:1.00-3.98), experience more housing instability (OR=1.97; CI:1.08-3.59), indicate higher importance of quitting (OR=1.27; CI:1.041.55), have higher NRT adherence (OR=1.75; CI:1.00-3.06), and lower odds of reported illicit drug use (OR=0.48; CI:0.24-0.95). CONCLUSIONS: Over half of participants reduced smoking by at least 50%, indicating reduction is feasible among homeless smokers. Further research is required to understand the impact of reduction on future cessation attempts in homeless smokers. This study shows that reduction is achievable and may be a valid intermediate goal.

The Association of Residential Mobility With Weight-Related Health Behaviors.

OBJECTIVE: To estimate associations of residential mobility with body mass index (BMI), physical activity, and diet and whether associations differ across demographics. DESIGN: Longitudinal cohort with 4 waves of survey follow-up over 15 years. PARTICIPANTS AND SETTING: A total of 2,110 adolescents and young adults originally from the Twin Cities of Minnesota responded to at least 2 waves of follow-up, beginning at ages 15 to 23 years. MAIN OUTCOME MEASURE(S): Self-reported BMI, physical activity, fast food consumption, breakfast frequency, sugary drink consumption, fruit and vegetable consumption, and screen time. ANALYSIS: Each outcome was modeled as a continuous variable using hierarchical linear regression. Residential mobility-change in residential address-was the main effect of interest. Models adjusted for demographics, marriage during follow-up, and previous level of the outcome. Inverse propensity weights accounted for loss to follow up. RESULTS: No weight-related outcomes differed between movers and nonmovers in the whole sample. When examining effect modification by age, as participants aged, moving was increasingly associated with improvements in weight-related outcomes, particularly BMI. CONCLUSIONS AND IMPLICATIONS: Results suggest that moving may be associated with poorer weight-related outcomes during a brief window from late teens and early-20s and less associated with weight-related outcomes in the mid-20s and 30s.

A Randomized Trial of Nicotine versus No-nicotine E-cigarettes Among African American Smokers: Changes in Smoking and Tobacco Biomarkers.

INTRODUCTION: The objective of this clinical trial was to compare the effects of e-cigarettes with and without nicotine on patterns of combustible cigarette use and biomarkers of exposure to tobacco toxicants among African American smokers. METHODS: African American smokers (n = 234) were enrolled in a 12-week, single blind, randomized controlled trial and assigned to ad lib use of nicotine e-cigarettes with or without menthol (2.4% nicotine [equivalent to combustible cigarettes], n = 118), or no-nicotine e-cigarettes (n = 116) for 6 weeks. Surveys were administered at baseline, 2, 6, and 12 weeks, and urinary biomarkers 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and total nicotine equivalents (TNE) were assessed at baseline and 6 weeks. RESULTS: Participants smoked an average of 11.4 cigarettes per day (CPD) and 88% used menthol cigarettes at baseline. At Week 6, the nicotine group reported using e-cigarettes 9.1 times per day compared to 11.4 times in the no-nicotine group (p = 0.42). Combustible cigarette smoking decreased 3.0 CPD in the nicotine group compared to 2.7 CPD in the no-nicotine group (p = 0.74). Neither TNE nor NNAL changed significantly between baseline and Week 6. There were no differences in nicotine withdrawal symptoms between treatment groups. Smoking reduction persisted in both groups at Week 12. CONCLUSIONS: Contrary to our hypotheses, nicotine e-cigarettes did not significantly reduce the use of combustible cigarettes compared to no-nicotine e-cigarettes in this cohort of African American smokers. Findings suggest e-cigarettes are modestly associated with the decreased use of combustible cigarettes among non-treatment seeking smokers, regardless of nicotine content, but without a reduction in tobacco toxicants. IMPLICATIONS: Although e-cigarettes have the potential to reduce harm if substituted for combusted cigarettes (or if they promoted cessation) because of lower levels of tobacco toxicants, this study suggests ad lib use of e-cigarettes among African American smokers, with or without nicotine, results in modest smoking reduction but does not change toxicant exposure in a cohort where smoking cessation or reduction is not the goal. These data suggest that testing future harm reduction interventions using e-cigarettes should include more specific behavioral change coaching, including substituting for or completely stopping combusted cigarettes.

Testing the Feasibility and Acceptability of a Religiously-Tailored Text Messaging Intervention to Reduce Smoking Among Somali Muslim Men During Ramadan.

INTRODUCTION: The prevalence of smoking among Somali Muslim male immigrants residing in Minnesota is estimated at 44%, however smoking reduction is common during the month of Ramadan. This study evaluated the feasibility and impact of a religiously tailored text message intervention delivered during Ramadan to encourage smoking reduction among Somali Muslim men who smoke. METHODS: Fifty Somali men were recruited. Participants received two text messages per day starting 1 week prior to and throughout the month of Ramadan. Approximately half were religiously tailored and half were about the risks of smoking and benefits of quitting. Smoking behavior was assessed at baseline, and at weeks 4 (end of Ramadan), 8, and 16. Outcomes included feasibility, acceptability, and preliminary impact of the text message intervention on smoking reduction and bioverified abstinence. RESULTS: The average age was 41 years. Average time to first cigarette was 1.8 hours at baseline, and 46% of participants smoked menthol cigarettes. Eighteen of 50 participants selected English and 32 selected Somali text messages. Subjects significantly reduced self-reported cigarettes per day (CPD) from 12.4 CPD at baseline to 5.8 CPD at week 16 (p < 0.001). Seven subjects reported quitting at week 16, five completed CO testing, confirming self-reported abstinence. The majority of participants found the cultural and religious references encouraging at the end of the week 16 survey. CONCLUSIONS: Religiously tailored text messages to decrease smoking are feasible and acceptable to Somali Muslim men who smoke during Ramadan. This intervention for addressing smoking disparities is worthy of further study. IMPLICATIONS: Recruitment of Somali Muslim men who smoke is feasible and supports the idea that further studies targeting smoking during Ramadan are practical. Ramadan presents a window of opportunity upon which to build smoking cessation interventions for smokers who identify as Muslim. These preliminary findings suggest that text messaging is a feasible and acceptable intervention strategy, and that religious tailoring was well received. Such an approach may offer potential for addressing smoking disparities among Somali Muslim male smokers. TRIAL REGISTRATION: ClinicalTrial.gov: NCT03379142.

Electronic cigarette use patterns and chronic health conditions among people experiencing homelessness in MN: a statewide survey.

BACKGROUND: Adults experiencing homelessness have higher rates of disease and premature morbidity compared to the general population. Tobacco use is a primary contributing factor to these disparities; however, less is known regarding e-cigarette use patterns among adults experiencing homelessness and whether e-cigarettes are used in a manner that is narrowing or widening health disparities. This study aimed to describe the 1) prevalence and trends in e-cigarette use, 2) correlates of e-cigarettes use, and 3) rates of chronic health conditions by product use pattern in a community-based sample of adults experiencing homelessness. METHODS: Adults experiencing homelessness in Minnesota were surveyed by self-report in 2015 (n = 3672) and 2018 (n = 4181) regarding e-cigarette and combustible cigarette use, potential correlates of e-cigarette use, and self-reported chronic health conditions (i.e., asthma, hypertension, diabetes, and cancer). RESULTS: Frequency of use increased from 2015 to 2018 for combustible cigarettes (66.9% vs. 72.3%), e-cigarettes (11.4% vs. 14.5%), and dual combustible/e-cigarette use (10.2% vs. 12.9%). The strongest bivariate correlates of past 30-day e-cigarette use were younger age, non-binary gender identification, non-heterosexual orientation, identification as White/Caucasian, greater frequency of lifetime homelessness, substance use, lack of regular place for medical care, mental health diagnosis, criminal justice involvement, and combustible cigarette smoking. Dual users had significantly higher rates of asthma and cancer than both those using combustible cigarettes and those using neither combustible nor e-cigarettes. CONCLUSIONS: During a time when cigarette smoking, e-cigarette use, and dual use were decreasing in the general population in Minnesota, rates increased in the homeless population. We observed that the rates of dual use were more than five times greater among homeless adults compared to the general population in 2018. Correlates of e-cigarette use were identified and should be used to identify subpopulations for intervention targeting. Mechanisms of the relationship between dual use and increased risks of health conditions deserve further study.

Text Message Support for Smoking Cessation During Ramadan: A Focus Group Study With Somali Immigrant Muslim Men.

INTRODUCTION: Somali Muslim male immigrants in Minnesota have a high prevalence of smoking, estimated at 44%, compared with the average smoking rate for adults in the United States (14%). However, the literature has reported spontaneous reductions of smoking during Ramadan. This study sought to gather the views of Somali Muslim men on how faith impacts their smoking, and determine what messaging to incorporate into a tailored text messages intervention that draws on the Muslim faith beliefs and practices during Ramadan to promote smoking cessation. METHODS: Thirty-seven Somali adult male smokers were recruited from community settings to participate in one of five focus groups in Minneapolis and Saint Paul, Minnesota. The research study team developed a semi-structured focus group guide that explored: (1) the experience of Muslim immigrants quitting smoking during Ramadan, (2) views on text messaging interventions to reduce smoking focusing on health and faith, and (3) views on the relationship between faith and smoking. A thematic analysis was conducted. RESULTS: Participants reported reductions in smoking during Ramadan, which was mostly achieved without formal treatment (ie, willpower). There was interest in text messaging interventions that incorporated faith and health-related messages, and that would be delivered around the time of Ramadan. Participants described concerns about the adverse health effects of smoking, including the risk of chronic health issues, cancer, and death. CONCLUSION: Combining faith and health-related text-based messaging, and tailoring interventions around and beyond Ramadan, maybe a valuable approach to help address smoking disparities in the Somali immigrant community. IMPLICATIONS: Ramadan offers a unique window of opportunity to intervene upon smoking for Somali Muslim immigrant men, for whom rates of smoking are high. Combining faith and health-related text-based messaging, and tailoring interventions around and beyond Ramadan, maybe a valuable approach to help address these serious smoking disparities.

Practical issues regarding implementing a randomized clinical trial in a homeless population: strategies and lessons learned.

There is a critical need for objective data to guide effective health promotion and care for homeless populations. However, many investigators exclude homeless populations from clinical trials due to practical concerns about conducting research with this population. This report is based on our experience and lessons learned while conducting two large NIH-funded randomized controlled trials targeting smoking cessation among persons who are homeless. The current report also addresses challenges when conducting clinical trials among homeless populations and offers potential solutions. Homeless individuals face several challenges including the need to negotiate daily access to food, clothing, and shelter. Some of the critical issues investigators encounter include recruitment and retention obstacles; cognitive impairment, mental health and substance abuse disorders; transportation and scheduling challenges; issues pertaining to adequate study compensation; the need for safety protocols for study staff; and issues related to protecting the wellbeing of these potentially vulnerable adults. Anticipating realistic conditions in which to conduct studies with participants who are homeless will help investigators to design efficient protocols and may improve the feasibility of conducting clinical trials involving homeless populations and the quality of the data collected by the researchers.

Integrating smoking cessation and alcohol use treatment in homeless populations: study protocol for a randomized controlled trial.

BACKGROUND: Despite progress in reducing cigarette smoking in the general U.S. population, smoking rates, cancer morbidity and related heart disease remain strikingly high among the poor and underserved. Homeless individuals' cigarette smoking rate remains an alarming 70% or greater, and this population is generally untreated with smoking cessation interventions. Furthermore, the majority of homeless smokers also abuse alcohol and other drugs, which makes quitting more difficult and magnifies the health consequences of tobacco use. METHODS/DESIGN: Participants will be randomized to one of three groups, including (1) an integrated intensive smoking plus alcohol intervention using cognitive behavioral therapy (CBT), (2) intensive smoking intervention using CBT or (3) usual care (i.e., brief smoking cessation and brief alcohol counseling). All participants will receive 12-week treatment with a nicotine patch plus nicotine gum or lozenge. Counseling will include weekly individual sessions for 3 months, followed by monthly booster group sessions for 3 months. The primary smoking outcome is cotinine-verified 7-day smoking abstinence at follow-up week 52, and the primary alcohol outcome will be breathalyzer-verified 90-day alcohol abstinence at week 52. DISCUSSION: This study protocol describes the design of the first community-based controlled trial (n = 645) designed to examine the efficacy of integrating alcohol abuse treatment with smoking cessation among homeless smokers. To further address the gap in effectiveness of evidence-based smoking cessation interventions in the homeless population, we are conducting a renewed smoking cessation clinical trial called Power to Quit among smokers experiencing homelessness.
