Health-Related Quality of Life Among Homeless Smokers: Risk and Protective Factors of Latent Class Membership.

Health-related quality of life (HRQoL) is a multidimensional assessment of well-being and health status. Most work in this area assumes that HRQoL is a homogenous construct; however, it is possible HRQoL subgroups may exist. The purpose of the study was to characterize common classes of HRQoL among adult, homeless smokers, a particularly vulnerable group of the larger population, and to evaluate risk and protective factors of HRQoL class membership. Homeless smokers (N = 456; 65.1% male; Mage = 43.19 years [SD = 11.77]) completed self-report measures of sociodemographics, smoking characteristics, anxiety sensitivity, stress, social support, and the Center for Disease Control (CDC) four-item HRQoL measure. A latent class analysis was conducted for HRQoL. Multinomial regression models were used to simultaneously test correlates of class membership. A three-class solution, consisting of poor HRQoL, moderate HRQoL, and excellent HRQoL, demonstrated superior fit. Correlates of class membership included sex, age, lifetime months of being homeless, smoking characteristics, anxiety sensitivity, stress, and social support. The current findings provide novel evidence for three distinct classes of HRQoL among homeless smokers. Results suggest that older smokers with greater emotional distress, as evidenced by greater anxiety sensitivity, greater stress, and less social support, may be particularly vulnerable to poorer HRQoL.

Exposure to Violence and Sleep Inadequacies among Men and Women Living in a Shelter Setting.

BACKGROUND: Exposure to violence may explain sleep inadequacies reported by homeless adults, with women being potentially more susceptible to violence and sleep disturbances than men. This study examined the association between violence and sleep inadequacies among homeless adults and explored differences by sex. METHODS: Adult participants were recruited from a shelter (N=194; 71.1% men, Mage = 43.8±12.2). Participants self-reported victimization and/or witnessing violence (mugging, fight, and/or sexual assault) at the shelter, sleep duration (over an average 24 hours), insufficient sleep (days without sufficient rest/sleep), and unintentional daytime sleep (days with unintentional sleep) in the past month. Linear regressions were used to estimate associations between violence and sleep inadequacies, controlling for sex, age, race, months homeless, and depression. Moderation by sex was examined via an interaction term following mean-centering of variables. RESULTS: Overall, 20.6% of participants (n=40) reported victimization since moving to the shelter. In the last month, participants reported witnessing an average of 2.9±5.1 acts of violence. Over the same timeframe, participants reported 6.9±2.0 hours of sleep nightly, 11.2±10.7 days of insufficient sleep, and 6.2±8.8 days with unintentional daytime sleep. In adjusted analyses, witnessing violence was associated with insufficient sleep (p=.001). Men and women differed only in age and race in unadjusted analyses; sex was not a significant moderator of any association between violence and sleep in adjusted analyses. CONCLUSIONS: Links between witnessing violence and sleep inadequacies should be considered in shelter health promotion efforts. Successful efforts to minimize violence may reduce insufficient sleep amongst both sexes.

The buffering effect of social support on the relationship between discrimination and psychological distress among church-going African-American adults.

Discrimination is a pervasive stressor among African-American adults. Social support is an important protective factor for psychological distress, especially among minority populations. Although a number of studies have examined social support in relation to discrimination, little research has examined how social support may serve as an important protective factor against both physical and psychological symptoms related to overall psychological distress within this group. The current study examined social support as a moderator of the relationship between discrimination and overall psychological distress as measured by the Brief Symptom Inventory among a community sample of 122 African-American church-going adults. Results indicated that social support buffered the associations of discrimination and overall psychological distress (p < 0.0001) in expected directions. Findings highlight the importance of cultivating strong social relationships to attenuate the effects of this social determinant on mental health disparities among this group.

Income associations with cigarette purchasing behaviors and quit attempts among people experiencing homelessness.

INTRODUCTION: Cigarette purchasing behavior may reflect quitting intentions. Little is known about how income could modify the association between cigarette purchasing behaviors and quit attempts among smokers experiencing homelessness. METHODS: Homeless, current smokers completed a questionnaire on the amount spent weekly on cigarettes (≤$20/week versus >$20/week), source of cigarettes (store versus other source), quantity of cigarettes purchased ($20/week on cigarettes, 83% reported purchasing cigarettes from a store, and 86% reported purchasing ≥pack during their last purchase. Those who reported an income spent a third of their monthly income on cigarettes, and were more likely to spend >$20/week on cigarettes. The amount spent weekly on cigarettes and the source of cigarettes was not associated with quit attempts, nor did income moderate these relationships. Persons without an income who bought a pack or more of cigarettes made fewer quit attempts (ß = -0.4, 95% CI -0.7, -0.2), whereas the association between quantity of cigarettes purchased and quit attempts was not significant for those with an income (ß = -0.2, 95% CI -0.4, 0.1). CONCLUSIONS: Current smokers experiencing homelessness and who are without an income may find it particularly challenging to engage in attempts to quit smoking. Smoking cessation interventions that highlight relief of financial hardship as a potential benefit of successfully quitting smoking may be useful among this population.

Characterizing Alcohol Use Behaviors among Homeless Men and Women.

Objectives: In this study, we characterized alcohol use behaviors by sex among sheltered homeless adults and explored associations with health and readiness to change drinking behaviors. Methods: Participants (N = 581; 63.7% men; Mage = 43.6, 29.4% white) self-reported alcohol use and readiness to change drinking behaviors. Sex differences were analyzed via Wilcoxon ranksum, chi-square tests, logistic regression, and ANCOVAs. Results: Overall, 38.5% of the sample met criteria for current at-risk drinking, 39.7% self-reported a history of alcohol problems, and 22.9% reported having a formal alcohol use disorder (AUD) diagnosis. Among current alcohol users, 83.8% reported at-risk drinking. Men had more drinks per drinking day, more drinks per week, and more drinking days per week when compared to women. No sex differences were found for at-risk drinking, self-reported alcohol problems, probable alcohol abuse/dependence, AUD diagnosis, readiness to change drinking, or recent alcohol/substance abuse counseling. Conclusions: High rates of at-risk drinking were found among alcohol users. Homeless men and women did not exhibit differences in several manifestations of problematic alcohol use. Alcohol use interventions might be equally appealing to both sexes given equivalent readiness to change drinking; however, rates of recent treatment receipt were low.

The moderating effect of perceived social support on the relation between heaviness of smoking and quit attempts among adult homeless smokers.

BACKGROUND: Over 70% of homeless adults smoke cigarettes. Despite the desire to quit, this group rarely receives the external support to make or maintain a successful quit attempt (SQA; intentional quit attempt lasting >24 h). The Heaviness of Smoking Index (HSI) is a cigarette dependence measure that independently predicts SQAs among domiciled adults. For homeless adults, social support may be a way to buffer the impact of cigarette dependence on SQAs. METHODS: The association of the HSI and past-year SQAs, and the potential moderating role of social support, was examined among 445 homeless smokers (Mage = 43.2 + 11.8, 65% male, 57.5% white). Support was measured by the International Support Evaluation List (ISEL-12) and its 3 subscales: tangible, belonging, & appraisal support. RESULTS: The HSI was negatively correlated with SQAs (r=-.283, p < .01) and in a regression model controlling for age, sex, and race/ethnicity, appraisal support significantly moderated this relationship (p < .05). The HSI was significantly related to SQAs across low, moderate, and high levels of appraisal support [mean, +1 SD; low (ß=-.657, p < .001), medium (ß=-.457, p < .001), and high (ß=-.258, p < .05)]. Neither the ISEL-12 total nor the other subscales were moderators. CONCLUSION: The perceived availability of someone to talk to about one's problems appeared to attenuate the strength of the inverse relationship between the heaviness of smoking and SQAs. Fostering appraisal support for homeless smokers through group treatment may reduce the impact of cigarette dependence on making quit attempts. Social support coupled with the increased availability of empirically-supported cessation aids may improve dismal quit rates among homeless adults.

Concurrent nicotine and tobacco product use among homeless smokers and associations with cigarette dependence and other factors related to quitting.

BACKGROUND: Cigarette smoking rates among homeless adults are exceptionally high, contributing to health disparities experienced by this disadvantaged population. Concurrent nicotine and tobacco product use have been shown to result in greater health problems than cigarette smoking alone, and little is known about the rates, motives, and perceived impacts of concurrent use in this group. The purpose of this study is to explore concurrent use rates and constructs of interest among homeless adult daily smokers and to examine differences between concurrent users and non-concurrent users on cigarette dependence, perceived risk of smoking, readiness to quit, and the receipt of recent cessation intervention. METHODS: Participants (N = 396) were recruited from six homeless-serving agencies and/or shelters in Oklahoma City. Enrolled participants completed self-report questionnaires. RESULTS: The rate of concurrent use was high -67.2%. Participants most frequently endorsed lower cost and a desire to cut down on cigarette smoking as motives for concurrent product use. Concurrent users indicated both a greater likelihood of developing a smoking-related disease if they did not quit for good and a greater number of past year quit attempts relative to non-concurrent users. There was no significant difference between concurrent users and non-concurrent users on readiness to quit or having received recent smoking cessation intervention. CONCLUSION: The need for cessation efforts that account for concurrent use for homeless adult smokers is great. Study findings indicate that concurrent users are commonly pursuing the reduction or elimination of cigarette usage and should be specifically targeted for cessation intervention.
