RESUMO
INTRODUCTION: Smoking prevalence in homeless populations is strikingly high (â¼70%); yet, little is known about effective smoking cessation interventions for this population. We conducted a community-based clinical trial, Power To Quit (PTQ), to assess the effects of motivational interviewing (MI) and nicotine patch (nicotine replacement therapy [NRT]) on smoking cessation among homeless smokers. This paper describes the smoking characteristics and comorbidities of smokers in the study. METHODS: Four hundred and thirty homeless adult smokers were randomized to either the intervention arm (NRT + MI) or the control arm (NRT + Brief Advice). Baseline assessment included demographic information, shelter status, smoking history, motivation to quit smoking, alcohol/other substance abuse, and psychiatric comorbidities. RESULTS: Of the 849 individuals who completed the eligibility survey, 578 (68.1%) were eligible and 430 (74.4% of eligibles) were enrolled. Participants were predominantly Black, male, and had mean age of 44.4 years (S D = 9.9), and the majority were unemployed (90.5%). Most participants reported sleeping in emergency shelters; nearly half had been homeless for more than a year. Nearly all the participants were daily smokers who smoked an average of 20 cigarettes/day. Nearly 40% had patient health questionnaire-9 depression scores in the moderate or worse range, and more than 80% screened positive for lifetime history of drug abuse or dependence. CONCLUSIONS: This study demonstrates the feasibility of enrolling a diverse sample of homeless smokers into a smoking cessation clinical trial. The uniqueness of the study sample enables investigators to examine the influence of nicotine dependence as well as psychiatric and substance abuse comorbidities on smoking cessation outcomes.

OBJECTIVE: To understand how factors at multiple levels of influence impact adolescent smoking initiation. METHOD: Data from the Minnesota Adolescent Community Cohort, a population-based cohort, were analyzed. Adolescents were recruited from randomly selected geopolitical units (GPUs) in Minnesota at ages 12 to 13 (n=1953), and were surveyed every six months (2000-2006) until 18. The association between baseline social factors and smoking initiation was analyzed using logistic regression. Linear regression was used to analyze predictors and age of initiation among smokers (n=603). RESULTS: Higher proportion of 15-16 year-olds who smoke at the area-level (GPU) was associated with younger initiation (15.47 vs 15.87, p<.05). Higher proportion of the population employed and higher median household income were associated with older initiation (15.90 vs. 15.56 p<.05). Parent education, living with parents or siblings who smoke, living in homes that allow smoking, and having friends who smoke at baseline were associated with smoking initiation or younger initiation (p<.05). Participants whose parents had less than a high school education were 1.6 times more likely than those with college educated parents to have smoked at least a whole cigarette (CI=1.06, 2.26). CONCLUSION: Factors at multiple levels of influence effect adolescent smoking initiation. Smoking by older age peers and lower SES predicts earlier smoking.

INTRODUCTION: Disparities in tobacco's harm persist. Declines in smoking among the general population have not been experienced to the same extent by vulnerable populations. Innovative strategies are required to diminish disparities in tobacco's harm. As novel tools, anthropological concepts and methods may be applied to improve the design and outcomes of tobacco cessation interventions. METHODS: We reviewed over 60 articles published in peer-reviewed journals since 1995 for content on anthropology and smoking cessation. The specific questions framing the review were: (a) "How can lessons learned from anthropological studies of smoking improve the design and effectiveness of smoking cessation interventions?" (b) How can anthropology be applied to diminish disparities in smoking cessation? and (c) How can qualitative methods be used most effectively in smoking cessation intervention research? RESULTS: Three specific disciplinary tools were identified and examined: (a) culture, (b) reflexivity, and (c) qualitative methods. Examining culture as a dynamic influence and understanding the utilities of smoking in a particular group is a precursor to promoting cessation. Reflexivity enables a deeper understanding of how smokers perceive quitting and smoking beyond addiction and individual health consequences. Qualitative methods may be used to elicit in-depth perspectives on quitting, insights to inform existing community-based strategies for making behavior changes, and detailed preferences for cessation treatment or programs. CONCLUSIONS: Anthropological tools can be used to improve the effectiveness of intervention research studies targeting individuals from vulnerable groups. Synthesized applications of anthropological concepts can be used to facilitate translation of findings into clinical practice for providers addressing tobacco cessation in vulnerable populations.

BACKGROUND: Our previous work has shown substantial national variation in the frequency of nephrology visits after kidney transplant. The low frequency of nephrology visits was associated with increased risk of transplant failure. METHODS: We performed a qualitative study that included interviews and 5 focus groups of transplant recipients. The study took place at a transplant center in the Upper Midwest. Participants (N = 39) were selected if they had at least one of the previously described risk factors for decreased nephrology visits: ethnic minority, lower median household income, and residence less than 10 miles from the transplant center. The goal was to assess patients' perceptions and beliefs and perceived barriers to regular nephrology outpatient visits. All transcripts were coded using software for qualitative data analysis. RESULTS: Transplant recipients understood the importance of keeping nephrology appointments and reflected positively on them. Regardless, they perceived barriers to adhering to the visit schedule, such as a value on self-reliance, which they described as increasing over time since transplant; a growing sense that they could interpret their bodies independently without needing to see the physician as regularly; and finally, the multitude of physical and mental health challenges inherent to posttransplant life. Other factors motivated patients to keep their regular nephrology visits, such as peer-support relationships and talking to other patients on dialysis therapy. Patients reported that talking to patients who had received a transplant before them helped them anticipate and cope with the mental and physical challenges associated with life posttransplant. A study limitation was that all participants were from a single transplant center. CONCLUSIONS: Although kidney transplant recipients understood the importance of keeping nephrology appointments, there were significant perceived barriers to these visits. Future interventions should address perceived barriers and motivate patients to keep regular nephrology visits posttransplant as a way to improve transplant outcomes.

BACKGROUND: Although smoking prevalence remains strikingly high in homeless populations (~70% and three times the US national average), smoking cessation studies usually exclude homeless persons. Novel evidence-based interventions are needed for this high-risk subpopulation of smokers. PURPOSE: To describe the aims and design of a first-ever smoking cessation clinical trial in the homeless population. The study was a two-group randomized community-based trial that enrolled participants (n = 430) residing across eight homeless shelters and transitional housing units in Minnesota. The study objective was to test the efficacy of motivational interviewing (MI) for enhancing adherence to nicotine replacement therapy (NRT; nicotine patch) and smoking cessation outcomes. METHODS: Participants were randomized to one of the two groups: active (8 weeks of NRT + 6 sessions of MI) or control (NRT + standard care). Participants attended six in-person assessment sessions and eight retention visits at a location of their choice over 6 months. Nicotine patch in 2-week doses was administered at four visits over the first 8 weeks of the 26-week trial. The primary outcome was cotinine-verified 7-day point-prevalence abstinence at 6 months. Secondary outcomes included adherence to nicotine patch assessed through direct observation and patch counts. Other outcomes included the mediating and/or moderating effects of comorbid psychiatric and substance abuse disorders. RESULTS: Lessons learned from the community-based cessation randomized trial for improving recruitment and retention in a mobile and vulnerable population included: (1) the importance of engaging the perspectives of shelter leadership by forming and convening a Community Advisory Board; (2) locating the study at the shelters for more visibility and easier access for participants; (3) minimizing exclusion criteria to allow enrollment of participants with stable psychiatric comorbid conditions; (4) delaying the baseline visit from the eligibility visit by a week to protect against attrition; and (5) regular and persistent calls to remind participants of upcoming appointments using cell phones and shelter-specific channels of communication. LIMITATIONS: The study's limitations include generalizability due to the sample drawn from a single Midwestern city in the United States. Since inclusion criteria encompassed willingness to use NRT patch, all participants were motivated and were ready to quit smoking at the time of enrollment in the study. Findings from the self-select group will be generalizable only to those motivated and ready to quit smoking. High incentives may limit the degree to which the intervention is replicable. CONCLUSIONS: Lessons learned reflect the need to engage communities in the design and implementation of community-based clinical trials with vulnerable populations.

BACKGROUND: The benefits of breastfeeding for infants and mothers have been well established, yet rates of breastfeeding remain well below national recommendations in the United States and even lower for women who smoke during pregnancy. Primary goals of this study were to explore contextual factors that contribute to breastfeeding intentions and behavior and to examine how smoking status affected women's decision making about breastfeeding. METHODS: This paper is based on a longitudinal qualitative study of smoking, pregnancy, and breastfeeding among 44 low-income women in the southwest U.S. who smoked during pregnancy. Each woman was interviewed 9 times; 6 times during pregnancy and 3 times postpartum using semistructured questionnaires. Interviews lasted 1 to 3 hours and were tape-recorded, transcribed, and analyzed. RESULTS: Despite 36 (82%) respondents stating that they intended to breastfeed for an average duration of 8 months, rates of breastfeeding initiation and duration were much lower than intentions. By 6 months postpartum, only two women were breastfeeding exclusively. CONCLUSIONS: Women perceived that a strong risk of harming the baby was posed by smoking while breastfeeding and received little encouragement to continue breastfeeding despite an inability to stop smoking. The perceptions of the toxic, addictive, and harmful effects of smoking on breastmilk constitution and quantity factored into reasons why women weaned their infants from breastfeeding much earlier than the recommended 6 months. The results indicate a need for more consistency and routine in educating women on the relationship between smoking and breastfeeding and in promoting breastfeeding in spite of smoking postpartum.

The authors present findings from a qualitative study on postpartum smoking among low-income women ( N = 44) who had been smokers at the onset of pregnancy. Interview data collected after delivery at Months 1, 3, and 6 postpartum are discussed to explore contextual factors contributing to smoking abstinence, relapse, and harm-reduction practices. By 6 months postpartum, 10 women (23%) had completely quit, 21 women (48%) had reduced their smoking by 50% of their prepregnancy levels, and 7 women (16%) had reduced their smoking by one third of their prepregnancy levels. Thus, the majority of the women were engaging in significant harm-reduction efforts despite being entrenched in high-risk smoking environments where they were provided with few messages to quit. Many mothers were concerned about their moral identity as a smoker and expressed concerns that their child might initiate smoking at an early age. Future programs targeting this population should acknowledge women's harm-reduction efforts in environments where smoking is normative.

This article presents findings from a qualitative study of 53 low-income women who were smokers at the onset of pregnancy. Study participants were interviewed during pregnancy to document smoking trajectories and factors contributing to, or undermining, harm reduction and quit attempts. Thirty percent of women quit smoking completely, 43% engaged in sustained harm reduction, and 26% reduced their smoking levels intermittently. Case studies of women are presented to illustrate reasons for quitting, harm reduction practices, and factors influencing relapse and smoking continuation. Women's motivations to quit are highlighted. Moral identity as a mother was found to be a key motivating factor behind women's quit attempts. Future programs targeting this population would do well to acknowledge moral identity as an issue and recognize the challenges of quitting for women with limited social support and little control over their immediate environment.

AIMS: To assess the effects of adding motivational interviewing (MI) counseling to nicotine patch for smoking cessation among homeless smokers. DESIGN: Two-group randomized controlled trial with 26-week follow-up. PARTICIPANTS AND SETTING: A total of 430 homeless smokers from emergency shelters and transitional housing units in Minneapolis/St Paul, Minnesota, USA. INTERVENTION AND MEASUREMENTS: All participants received 8-week treatment of 21-mg nicotine patch. In addition, participants in the intervention group received six individual sessions of MI counseling which aimed to increase adherence to nicotine patches and to motivate cessation. Participants in the standard care control group received one session of brief advice to quit smoking. Primary outcome was 7-day abstinence from cigarette smoking at 26 weeks, as validated by exhaled carbon monoxide and salivary cotinine. FINDINGS: Using intention-to-treat analysis, verified 7-day abstinence rate at week 26 for the intervention group was non-significantly higher than for the control group (9.3% versus 5.6%, P = 0.15). Among participants who did not quit smoking, reduction in number of cigarettes from baseline to week 26 was equally high in both study groups (-13.7 ± 11.9 for MI versus -13.5 ± 16.2 for standard care). CONCLUSIONS: Adding motivational interviewing counseling to nicotine patch did not increase smoking rate significantly at 26-week follow-up for homeless smokers.

Health services for undocumented migrants highlight the complex politics of the "right to health". South-South migrants, an emerging focus of migration scholarship, compose an estimated 40 percent of the world's 200 million international migrants. In Costa Rica, internationally renowned for its public health achievements, undocumented Nicaraguan migrants number between 8 and 16 percent of the population. In spite of historical, linguistic, and ethnic congruencies between peoples of the sending and receiving countries at the ends of this migratory path, access to health services is limited for migrants experiencing illegality in the global economic South. Costa Rican health providers articulated concepts of deservingness to health services for undocumented Nicaraguan migrants. This article is based on a preliminary study with a purposive sample of 22 Costa Rican health services providers. Interviewed over two field research periods (June 2005-July 2006; July, 2008), providers addressed four types of health services for undocumented migrants. Overall their views on the deservingness of health services for undocumented migrants reflected a utilitarian approach. Specifically, their talk reflected: (1) the limits to state responsibility for ensuring the health of individuals not pertaining to the nation; and (2) a concern for the threats posed to the health of Costa Rican nationals. Costa Rican providers' perceptions on health services for migrants offer partial insight for the development of future migrant health policies in receiving countries of the global economic South.

PURPOSE: To describe the factors associated with interest of homeless former smokers in helping homeless smokers quit. METHODS: A cross-sectional survey administered to an optimized convenience sample of homeless persons (n â=â 4570) at emergency shelters, transitional housing units, and open encampments in 80 cities across Minnesota. The in-person survey response rate was 90%. ANALYSIS: Chi-square tests and t-tests for univariate analysis. RESULTS: Of 4534 participants completing the smoking questions, 546 participants (12%) self-identified as former smokers, of which 59% expressed interest in helping homeless smokers quit. Significant predictors of reported interest in helping included racial/ethnic background (p < .05), number of people known who had quit smoking (p < .01), and receiving social services as an adult (p < .01). CONCLUSION: Homeless former smokers are a potential resource for peer support programs to promote smoking cessation among homeless current smokers.

OBJECTIVES: To determine if community subjective social status (SSS) predicted smoking abstinence through 26 weeks postrandomization among 755 African American light smokers of low SES (socioeconomic status). METHODS: Participants were enrolled in a double-blind, placebo-controlled, randomized clinical trial, which examined the efficacy of nicotine gum and counseling for smoking cessation. RESULTS: Results indicated that SSS predicted smoking abstinence over time [P=.046; odds ratio (OR) =1.075 (1.001-1.155)] after adjusting for covariates. CONCLUSIONS: Further research is needed to understand the effects of community SSS on smoking cessation among heavy smokers and other ethnic groups.

This article presents findings from an ethnographic study of 43 Nicaraguan labor migrant women in Costa Rica, among whom two thirds were undocumented. Drawing from more than a year of field research, this research explores how undocumented migrant women parlayed reproductive capacities in a context of a modernizing democratic host nation-state increasingly limited in its capacity to fulfill longstanding national ideals of "health for all." Pregnancy and postpartum periods presented unique opportunities for achieving gains related to citizenship. As the third most common migrant destination context in the Western hemisphere, Costa Rica is grappling with its dual role as a nation of emigration and immigration and is attempting to maintain its "exceptional" national identity in the face of rapid globalization. Due to the jus soli citizenship model, the health care system has become a site for struggle over inclusion in the Costa Rican nation-state.
