Objective: To further characterize clinical characteristics, etiologic factors, associated disorders, and treatment of palmoplantar pustulosis (PPP)., Patients and Methods: We conducted a retrospective review of patients with PPP at Mayo Clinic between January 1, 1996, and December 31, 2013., Results: Of 215 patients with PPP identified, 179 (83%) were female, and the mean age at onset was 45.3 years. Most patients (n=165, 77%) were current or former smokers. At diagnosis, 15 patients (7%) had an anxiety diagnosis and 9 (4%) had an infection. Nineteen cases (9%) were drug induced. Comorbid conditions included thyroid disease in 18 patients (8%), gluten sensitivity in 3 (1%), and type 2 diabetes mellitus in 21 (10%). In all, 194 patients (90%) received topical corticosteroids, 55 (26%) received phototherapy, and 54 (25%) received systemic agents., Conclusion: More than three-fourths of the patients in this study had a history of smoking, which is considered a triggering or aggravating factor for PPP. Regarding comorbid conditions, gluten sensitivity and thyroid disease were found less frequently than previously reported in the literature. Treatment regimens and responses in this cohort varied considerably., (Copyright © 2017 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc. All rights reserved.)

We investigated class clustering patterns of four behaviors--physical activity, fruit and vegetable (F&V) intake, smoking, and alcohol use--in a faith-based African American cohort. Guided by socio-ecological models, we also examined the psychosocial and neighborhood social environmental factors associated with the clustering patterns. Participants were 1,467 African American adults recruited from a mega church in the metropolitan Houston, TX, in 2008-2009. They completed a survey and health assessment. Latent class analysis and multinomial regression analysis were conducted. Results supported a three-class model: Class 1 was characterized by low physical activity, low F&V intake, and low substance use (smoking and alcohol use). Class 2 was characterized by high physical activity, low F&V intake, and mild drinking. Class 3 seemed to be the healthiest group, characterized by high physical activity, moderate-to-high F&V intake, and low substance use. The probabilities of being included in Classes 1, 2, and 3 were 0.33, 0.48, and 0.19, respectively. Participants in Class 1 (vs. Class 3) reported lower physical activity norm (p < 0.001) and higher smoking norm (p = 0.002) and lower neighborhood social cohesion (p = 0.031). Participants in Class 2 (vs. Class 3) reported higher cancer risk perception (p < 0.001), lower F&V norm (p = 0.022), lower physical activity norm (p < 0.001), higher smoking norm (p < 0.001), and lower social cohesion (p = 0.047). As health behaviors are clustered together, future interventions for African Americans may consider targeting multiple health behaviors instead of targeting a single health behavior. Interventions addressing social norm and neighborhood social cohesion may enhance multiple health behaviors engagement in this population.

Objective: Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Method: Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a bootstrapping procedure to test the indirect effects. Results: Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. Conclusions: The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, whereas affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse.

Ecological momentary assessment (EMA), a data collection method commonly employed in mHealth studies, allows for repeated real‐time sampling of individuals' psychological, behavioral, and contextual states. Due to the frequent measurements, data collected using EMA are useful for understanding both the temporal dynamics in individuals' states and how these states relate to adverse health events. Motivated by data from a smoking cessation study, we propose a joint model for analyzing longitudinal EMA data to determine whether certain latent psychological states are associated with repeated cigarette use. Our method consists of a longitudinal submodel—a dynamic factor model—that models changes in the time‐varying latent states and a cumulative risk submodel—a Poisson regression model—that connects the latent states with the total number of events. In the motivating data, both the predictors—the underlying psychological states—and the event outcome—the number of cigarettes smoked—are partially unobservable; we account for this incomplete information in our proposed model and estimation method. We take a two‐stage approach to estimation that leverages existing software and uses importance sampling‐based weights to reduce potential bias. We demonstrate that these weights are effective at reducing bias in the cumulative risk submodel parameters via simulation. We apply our method to a subset of data from a smoking cessation study to assess the association between psychological state and cigarette smoking. The analysis shows that above‐average intensities of negative mood are associated with increased cigarette use. [ABSTRACT FROM AUTHOR]

Introduction Recruiting special populations to smoking cessation trials is challenging and approaches beyond in-clinic recruitment may be beneficial. This secondary analysis of data from a smoking cessation RCT for individuals with a history of cervical cancer or cervical intraepithelial neoplasia (CIN) explored differences associated with in-clinic vs. online recruitment. Aims and Methods Participants were recruited from clinics within a university-based NCI-designated cancer center (n  = 87) and online nationally via Facebook (n  = 115). Baseline measures included sociodemographics, smoking history, and cancer or CIN history. Study retention and smoking abstinence were assessed 12 months post-baseline. Group differences in baseline characteristics were evaluated. Retention and abstinence were evaluated while controlling for group differences and predictors. Results Participants recruited online (vs. in-clinic) had higher educational attainment (p  = .01) and health literacy (p  = .003). They were more likely to have CIN versus cancer, to be further from the time of diagnosis, and to have completed active treatment (p values < .001). While controlling for these group differences and independent predictors, retention was higher among participants recruited online (log-likelihood χ2(1) = 11.41, p  < .001). There were no recruitment differences in self-reported (p  = .90) or biochemically confirmed smoking abstinence (p  = .18). Conclusions Compared to individuals recruited in-person, individuals recruited online were more educated, had higher health literacy, and presented with a different clinical profile (ie, more likely to have CIN vs. cancer and to have completed active treatment). There were few differences in participant characteristics between recruitment approaches, and no differences on any smoking-related variables. Online recruitment has the potential to improve enrollment of cancer survivors in smoking cessation trials. Implications People with a history of CIN or cervical cancer recruited to a smoking cessation RCT online (vs. in-clinic) were more likely to have a diagnosis of CIN versus cancer and were more educated and health literate. Participants recruited online were more likely to be retained in the study and there were no differences in smoking abstinence rates at 12 months. Incorporating online recruitment increased the reach of tobacco treatment efforts to a larger and more diverse sample. This could reduce the burden of tobacco-related disease, improve CIN and cancer treatment outcomes, and reduce secondary malignancies and morbidity among this underserved group.

Background and Aims: Individuals of lower socio‐economic status (SES) display a higher prevalence of smoking and have more diffxiculty quitting than higher SES groups. The current study investigates whether the within‐person associations of key risk (e.g. stress) and protective (self‐efficacy) factors with smoking lapse varies by facets of SES. Design and setting: Observational study using ecological momentary assessment to collect data for a 28‐day period following a smoking quit attempt. Multi‐level mixed models (i.e. generalized linear mixed models) examined cross‐level interactions between lapse risk and protective factors and indicators of SES on smoking lapse. Participants: A diverse sample of 330 adult US smokers who completed a larger study examining the effects of race/ethnicity and social/environmental influences on smoking cessation. Measurements: Risk factors included momentary urge, negative affect, stress; protective factors included positive affect, motivation, abstinence self‐efficacy; SES measures: baseline measures of income and financial strain; the primary outcome was self‐reported lapse. Findings Participants provided 43 297 post‐quit observations. Mixed models suggested that income and financial strain moderated the effect of some risk factors on smoking lapse. The within‐person association of negative [odds ratio (OR) = 0.967, 95% CI= 0.945, 0.990, P < 0.01] and positive affect (OR = 1.023, 95% CI = 1.003, 1.044, P < 0.05) and abstinence self‐efficacy (OR = 1.020, 95% CI = 1.003, 1.038, P < 0.05) on lapse varied with financial strain. The within‐person association of negative affect (OR = 1.005, 95% CI = 1.002, 1.008, P < 0.01), motivation (OR = 0.995, 95% CI = 0.991, 0.999, P < 0.05) and abstinence self‐efficacy (OR = 0.996, 95% CI = 0.993, 0.999, P < 0.01) on lapse varied by income. The positive association of negative affect with lapse was stronger among individuals with higher income and lower financial strain. The negative association between positive affect and abstinence self‐efficacy with lapse was stronger among individuals with lower financial strain, and the negative association between motivation and abstinence self‐efficacy with lapse was stronger among those with higher income. The data were insensitive to detect statistically significant moderating effects of income and financial strain on the association of urge or stress with lapse. Conclusion: Some risk factors (e.g. momentary negative affect) exert a weaker influence on smoking lapse among lower compared to higher socio‐economic status groups. [ABSTRACT FROM AUTHOR]

Latine adults who smoke have a low probability of receiving evidence-based smoking cessation interventions. Acceptance and Commitment Therapy (ACT) has shown to be efficacious for treating tobacco dependence, but its usefulness for Latine populations is just emerging and has not been studied in the context of a culturally tailored treatment. This single-arm study evaluated the feasibility of recruitment and retention, and treatment acceptability of the PRESENT Wellness Program: a culturally relevant ACT-based smoking cessation treatment for Latine adults who also experience psychological distress. Secondary objectives were the examination of smoking rates and levels of depression, anxiety, and psychological inflexibility (ACT core target) among Latine adults. Taking place during the COVID-19 pandemic, the treatment entailed 8 sessions delivered via telehealth (1 in-person/video and 7 by phone), and nicotine patches. Participants (N = 23) completed baseline assessments and follow-ups 1-week post-end of treatment (EOT) and 2-months post EOT. Most participants were women (70%), ranging from young adult to middle-aged, born in the US (57%), working full time (52.2%), and reporting financial strain (70%). Average number of sessions completed was 5.5. Follow-up rates were 61% at both follow-ups. The program was acceptable as indicated by quantitative and qualitative measures. Point-prevalence smoking abstinence was 35% at both follow-ups. Participants reported an average decline across time [% or M(SD)] in all secondary measures, as follows: everyday smoking [Baseline = 87%; 1-wk post EOT = 13%; 2 mo post EOT = 8.7%]; depression [Baseline = 13.7(6.3); 1-wk post EOT = 9.9 (6.6); 2 mo post EOT = 7.4 (5.8)]; anxiety [Baseline = 12.7 (5.4); 1-wk post EOT = 9.7 (6.4); 2 mo post EOT = 8.1 (5.2)]; and psychological inflexibility [Baseline = 50.6 (7.2); 1-wk post EOT = 33.0 (10.7); 2 mo post EOT = 32.6 (12.4)]. The current study observed that implementation of an acceptance-based smoking cessation treatment delivered in a hybrid mode is feasible and acceptable for English-speaking Latine persons. The PRESENT Wellness Program shows promise to address smoking and behavioral health challenges in the Latine community. Replication and expansion of the study is warranted, including the linguistic adaptation and evaluation of the program among Spanish-preferring Latine persons who smoke. • Telehealth ACT-based intervention was feasible among Latine people who smoke. • Latine individuals achieved 35% smoking abstinence after ACT-based intervention. • Depression, anxiety & psychological inflexibility decreased after the intervention.

Background: The prevalence of smoking among cervical cancer survivors is strikingly high, yet no smoking cessation interventions to date have specifically targeted this population. This paper describes the study design, methods, and data analysis plans for a randomized clinical trial designed to evaluate the efficacy of a theoretically and empirically based Motivation And Problem Solving (MAPS) approach for promoting and facilitating smoking cessation among cervical cancer survivors. MAPS is a comprehensive, dynamic, and holistic intervention that incorporates empirically supported cognitive behavioral and social cognitive theory–based treatment strategies within an overarching motivational framework. MAPS is designed to be appropriate for all smokers regardless of their motivation to change and views motivation as dynamically fluctuating from moment to moment throughout the behavior change process. Objective: This 2-group randomized controlled trial compares the efficacy of standard treatment to MAPS in facilitating smoking cessation among women with a history of high-grade cervical dysplasia or cervical cancer. Methods: Participants (N=202) are current smokers with a history of high-grade cervical dysplasia or cervical cancer recruited nationally and randomly assigned to one of two treatment conditions: (1) standard treatment (ST) or (2) MAPS. ST consists of repeated letters referring participants to their state’s tobacco cessation quitline, standard self-help materials, and free nicotine replacement therapy when ready to quit. MAPS has all ST components along with 6 proactive telephone counseling sessions delivered over 12 months. The primary outcome is abstinence from tobacco at 18 months. Secondary outcomes include abstinence over time across all assessment points, abstinence at other individual assessment time points, quit attempts, cigarettes per day, and use of state quitlines. Hypothesized treatment mechanisms and cost-effectiveness will also be evaluated. Results: This study was approved by the institutional review boards at the University of Texas MD Anderson Cancer Center, the University of Oklahoma Health Sciences Center, and Moffitt Cancer Center. Participant enrollment concluded at Moffitt Cancer Center in January 2020, and follow-up data collection was completed in July 2021. Data analysis is ongoing. Conclusions: This study will yield crucial information regarding the efficacy and cost-effectiveness of a MAPS approach for smoking cessation tailored to the specific needs of women with a history of high-grade cervical dysplasia or cervical cancer. Findings indicating that MAPS has substantially greater efficacy than existing evidence-based tobacco cessation treatments would have tremendous public health significance. [ABSTRACT FROM AUTHOR]

Objectives: One way to enhance the impact of smoking health risk messages may be to tailor their content to individual difference factors such as need for cognition (NFC). In this study, we examined how NFC influenced responses to different smoking risk messages. Outcomes included knowledge, risk perceptions, and behavioral expectations related to quitting smoking. Methods: We randomized 402 participants to one of 4 different risk message sets that were manipulated in terms of emotionality and framing in a 2x2 design: (1) factual gain-framed, (2) factual loss-framed, (3) emotional gain-framed, and (4) emotional loss-framed. Results: Statistically significant main effects emerged for NFC and emotionality. For certain risk perceptions, those with lower NFC reported greater perceived risk in response to emotional messages and lower risk in response to factual messages; those with higher NFC showed an opposite pattern. Similarly, those with lower NFC reported greater risk in response to gain-framed messages and lower risk in response to loss-framed messages; the opposite pattern emerged for those lower in NFC. Conclusions: Findings highlight the importance of an individual difference variable in influencing the impact of different types of smoking risk messages. [ABSTRACT FROM AUTHOR]

Objectives: We investigated the treatment needs and preferences of low socioeconomic status cervical cancer survivors to inform the adaptation of a theoretically- and empirically-based Motivation and Problem-Solving approach to facilitate cessation in this at-risk population. Methods: Individual in-depth interviews were conducted with 12 female smokers with cervical cancer. Interviews were audio-recorded, transcribed, and analyzed using NVivo 10. Results: Most participants did not believe that smoking caused cervical cancer and attributed their diagnosis solely to human papillomavirus. They suggested that cessation treatment for cervical cancer survivors include psychoeducation about the impact of smoking on health and cancer and the benefits of quitting, pharmacotherapy, planning for quitting, strategies for coping with cravings/withdrawal, social support, real-time support, a nonjudgmental and understanding counselor, tailoring, and follow-up. They recommended that negativity/judgment and being told that "smoking is bad" not be included in treatment. Participants also suggested that treatment address stress management, issues specific to cervical cancer survivorship, and physical activity and healthy eating. Conclusions: Results highlight the unique treatment needs of low socioeconomic status smokers with cervical cancer and will inform the adaptation of an existing evidence-based intervention to encourage smoking cessation in this population.

Introduction: Varenicline and bupropion are two effective smoking cessation pharmacotherapies. Researchers have hypothesized that they might be effective, in part, because they reduce cue reactivity and cue-induced cravings. Here, we used event-related potentials (ERPs) to directly measure brain responses to cigarette-related and other motivationally relevant images during a pharmacologically aided quit attempt.Methods: Smokers involved in a 12-week placebo-controlled double-blind clinical trial of smoking cessation medications (varenicline, bupropion, placebo) took part in the study. We assessed participants at two time points: 24 h (n = 140) and 4 weeks (n = 176) after the quit date. At both sessions, we measured the amplitude of the late positive potential (LPP), an ERP component reliably associated with motivational relevance, and self-reported tonic craving using the brief version of the Questionnaire of Smoking Urges (QSU-Brief).Results: At both sessions, emotional and cigarette-related images evoked significantly larger LPPs than neutral images. Neither drug type nor smoking abstinence altered this effect at either session. At both sessions, varenicline and bupropion significantly reduced self-reported tonic craving relative to the placebo condition.Conclusions: While both varenicline and bupropion reduced self-reported tonic craving, neither medication altered the amplitude of the LPP to cigarette-related or emotional pictures in smokers attempting to quit. These medications may influence abstinence by means other than by reducing neuroaffective responses to cigarette-related cues. Smokers should be prepared for the likelihood that even after several weeks of successful abstinence, once treatment ends, cigarette-related cues may remain motivationally relevant and trigger cravings that might lead to relapse.Implications: Bupropion and varenicline do not alter electrophysiological responses, as measured by the LPP, to cigarette-related and emotional images. These findings help explain why cigarette-related cues can trigger relapse when smoking cessation medication treatments end. [ABSTRACT FROM AUTHOR]

Objectives: Few studies have examined the use of complementary health practices (e.g., mind/body practices and dietary supplements) among African Americans, particularly those who identify as being spiritual and/or religious. Furthermore, research on the health and health behavior profiles of such complementary health users is scant. The purpose of this study was to explore the use of complementary health practices and their lifestyle and health indicator correlates in a large, church-based African American population. Design: Cross-sectional analysis of 1467 African American adults drawn from a church-based cohort study. Participants reported use of complementary health practices, lifestyle behaviors (e.g., diet and smoking status), and health indicators (e.g., physical health and medical problems). Multiple logistic regressions were conducted to examine associations between lifestyle variables, health indicators, and use of complementary health practices. Outcome measures: Outcomes included prevalence of mind/body practices (e.g., meditation and Reiki) and dietary supplements (multivitamins) along with health indicator and lifestyle correlates of use. Results: Use of complementary health practices was high; 40% reported using any mind/body practice and 50% reported using dietary supplements. Poorer physical health was associated with use of mind/body practices, while likelihood of meeting fruit and vegetable recommendations was significantly associated with dietary supplement use. Conclusions: Complementary health practices were used heavily in a church-based sample of African American adults. Poorer physical health was associated with use of complementary health practices, yet users also displayed health conscious behaviors. Given the high engagement in complementary health practices, it may be prudent to consider adapting complementary health approaches for use in wellness interventions targeting African Americans in faith-based settings.

Abstract: Background and Aims: Despite the availability of several efficacious smoking cessation treatments, fewer than 25% of smokers who quit remain abstinent 1 year post‐treatment. This study aimed to determine if varenicline and bupropion combination treatment would result in higher abstinence rates than varenicline alone. Design: A double‐blind, randomized, parallel‐group smoking cessation clinical trial in which participants were exposed to 12 weeks of treatment and followed for 12 months. Setting: Hospital‐based out‐patient clinic in Texas, USA specializing in cancer prevention. Participants: A total of 385 community smokers (58.44% male) who smoked 1 pack of cigarettes/day [mean = 19.66 cigarettes/day, standard deviation (SD) = 9.45]; had average carbon monoxide (CO) of 26.43 parts per million (SD = 13.74); and were moderately dependent (Fagerström Test for Cigarette Dependence = 4.79; SD = 2.07). Interventions and comparator: Smokers were randomized in a 3 : 1 (active: Placebo) ratio to 12 weeks of treatment as follows: placebo (n = 56), varenicline (Var; n = 166), and varenicline + bupropion (Combo; n = 163). Measurements: A priori primary outcome: prolonged abstinence at 12 months. Secondary outcomes: 7‐day point prevalence abstinence and continuous abstinence; all abstinence measures at end of treatment and 6‐month follow‐ups. Findings: Intention‐to‐treat analysis: the Combo group (n = 163) failed to demonstrate superiority to the Var group (n = 166) for prolonged abstinence at 12 months [odds ratio (OR) = 0.91, 95% confidence interval (CI) = 0.50–1.64], supported by Bayes factor = 0.06. Both the Var (OR = 6.66, 95% CI = 1.61–59.27) and Combo groups (OR = 6.06, 95% CI = 1.45–54.09) demonstrated superiority to the Placebo group (n = 56; score = 8.38, P < 0.016). Conclusions: The addition of bupropion to varenicline treatment does not appear to increase smoking abstinence rates above that of varenicline alone. The findings support previous research showing a consistently favorable effect of both varenicline and the combination of varenicline and bupropion on smoking cessation compared with placebo.

Background: Efforts are needed to ensure that smokers with lower health literacy are provided with understandable and impactful information about the health consequences of smoking and benefits of quitting.Purpose: To test the influence of health literacy on smokers' responses to health risk messages manipulated on framing (gain vs. loss) and emotionality (factual vs. emotional).Methods: Participants (N = 402) were randomized to evaluate one of four sets of smoking risk messages (factual gain-framed, factual loss-framed, emotional gain-framed, or emotional loss-framed). Multiple linear regressions examined main effects of health literacy, message emotionality, and message framing on: (a) risk perceptions, (b) behavioral expectations (i.e. cut down, limit, quit), and (c) risk knowledge. Two-way interactions of health literacy with emotionality and framing were examined for these outcomes. Analyses were based on theory-driven, a priori hypotheses.Results: As hypothesized, main effects emerged such that smokers with higher health literacy reported stronger risk perceptions and knowledge retention regardless of message type. Additionally, emotional (vs. factual) and gain- (vs. loss-) framed messages were associated with certain lower risk perceptions regardless of health literacy level. Consistent with hypotheses, two-way crossover interactions emerged between health literacy and emotionality. Among smokers with higher health literacy, factual messages produced higher perceived risk and stronger expectations for quitting. Among smokers with lower health literacy, emotional messages produced higher perceived risk and stronger expectations for quitting.Conclusions: Health literacy plays an important role in influencing how smokers respond to different risk messages. One's health literacy should be considered when determining whether risk communications emphasize factual or emotional content. [ABSTRACT FROM AUTHOR]

Background: Mindfulness (or "Mindful Attention") has been described as the presence or absence of attention to, and awareness of, what is occurring in the present moment. Among smokers, greater mindfulness is associated with greater effect stability and reduced cue-induced craving. While studies have shown that mindfulness is associated with other smoking-related factors such as reduced withdrawal symptoms using cross-sectional data, relatively little is known about the associations between baseline mindful attention and future abstinence-related effect/withdrawal. The current study sought to examine whether levels of mindful attention before cessation predicts negative affect, withdrawal, and level of expired carbon monoxide (CO) on quit day, and also 3 and 7 days after quitting, during a selfquit attempt. Methods: Data from 58 adults (mean age=34.9; 65.5% male) participating in a self-quit study were available for analysis. Selfreport measures of mindful attention, negative affect, and withdrawal symptoms were collected. Biochemical measurement of expired CO was also collected. Dependent variables were assessed on quit day, and also 3 and 7 days after quitting. Covariates included age, race, sex, self-reported level of cigarette dependence, and smoking status through 7 days. Multivariate regression was used to evaluate the association of baseline mindful attention in relation to the studied outcomes. Results: Greater mindful attention predicted lower negative affect and reduced withdrawal at all 3 time-points. Mindful attention did not predict levels of expired CO. Conclusions: The findings suggest that mindful attention before or during smoking-cessation treatment may help to reduce negative affect and withdrawal, which serve as barriers to cessation for many smokers.

Objective: Risk behaviors associated with food insecurity, such as smoking, are a concern. This study examined a potential mechanism that links smoking and food insecurity. Methods: A community sample of 238 adults from Dallas, Texas participated in a cross-sectional survey. Smoking status was self-reported and biochemically-verified. The Financial Strain Questionnaire was used. Food insecurity was based on a 2-item screener. Covariate-adjusted regression models were conducted and indirect effects were assessed using bootstrapping methods outlined by Preacher and Hayes. Results: Smoking was positively related to financial strain and financial strain was positively related to food insecurity. Financial strain reduced the association between smoking and food insecurity. Conclusion: Linking established risk reduction programs with food assistance programs is needed to decrease the negative health impacts of food insecurity. [ABSTRACT FROM AUTHOR]

Key modifiable risk behaviors such as smoking, poor diet and physical inactivity often cluster and may have multiplicative adverse effects on health. This study investigated barriers and facilitators to healthy eating and physical activity (PA) in overweight Mexican-origin smokers to inform the adaptation of an evidence-based smoking cessation program into a multiple health behavior change intervention. Five focus groups were conducted with overweight Mexican-origin men (n = 9) and women (n = 21) who smoked. Barriers and facilitators of healthy eating and PA were identified, and gender differences were assessed. Participants expressed some motivation to eat healthfully and identified strategies for doing so, yet many women experienced difficulties related to personal, family and work-related circumstances. Barriers to healthy eating among men were related to food preferences and lack of familiarity with fruits and vegetables. Participants performed PA primarily within the context of work and domestic responsibilities. Stress/depressed mood, lack of motivation and concern for physical well-being limited further PA engagement. Routines involving eating, PA and smoking highlight how these behaviors may be intertwined. Findings emphasize the importance of social, structural and cultural contexts and call for additional investigation into how to integrate healthy eating and PA into smoking cessation interventions for overweight Mexican-origin smokers.

We examined cross-sectional associations of health literacy (HL) with smoking and other established health indicators among 1,467 African American adults. Data emanated from a longitudinal cohort study designed to investigate cancer risk factors among church-going African American adults. We conducted linear and logistic regression analyses to assess associations between HL and health indicators. HL was assessed using an established single-item screening question. Outcomes included indicators of poor physical health (cigarette smoking, self-rated general and physical health) and mental health (self-rated mental health, depressive symptoms, perceived stress). Nearly 19% of participants had low HL. Low HL was significantly associated with current smoking, poorer self-rated general and physical health, and higher perceived stress (ps < .05) even after we controlled for demographic variables (i.e., age, gender, relationship status) and indicators of socioeconomic status (i.e., education, income, insurance status). Low HL appears to be an independent risk factor for smoking and other indicators of poor physical and mental health in a large sample of African American adults. Future directions and clinical implications are discussed. [ABSTRACT FROM PUBLISHER]

Nearly half of U.S. adults have health literacy (HL) difficulties, and lack the ability to effectively obtain, process, and understand health information. Poor HL is associated with depression, yet mechanisms of this relation are unclear. This study examined whether social support mediated the relation between HL and depressive symptoms in 200 low-socioeconomic status (SES), racially/ethnically diverse smokers enrolled in cessation treatment. Mediation analyses were conducted using bootstrapping and controlling for SES and nicotine dependence. In simple mediation models, social support [Interpersonal Support Evaluation List (ISEL) total, subscales (Appraisal, Belonging, Tangible)] mediated the effect of HL on depression, such that lower HL was associated with lower perceived support, which predicted higher depressive symptoms ( ps < .05). A multiple mediation model, with ISEL subscales entered simultaneously as mediators, was significant ( p < .05) but only the Belonging subscale demonstrating independent significance ( p < .05). Thus, social support may be a critical factor underlying the HL-depression relationship in low-SES, racially/ethnically diverse smokers. [ABSTRACT FROM AUTHOR]

The article focuses on a study which examines the role of mindfulness in emotion regulation during the course of smoking cessation treatment among low-socioeconomic status African American smokers, who are at the risk of tobacco-related health disparities. Topics discussed include assessment of depressive symptoms during smoking cessation treatment, impact of mindfulness-based treatments on volatility index, and association of mindfulness with emotional stability.

The article discusses research which investigated link between perceived discrimination, depressive symptoms and cancer risk factors in African American adults residing in Houston, Texas. It reports data collection procedures performed, sociodemographic characteristics of subjects, and measurement of their perceived stress. An assessment of obesity, fruit and vegetable intake and physical activity of concerned adults is given. It also describes various behavioral risk factors recorded.

Objectives: To evaluate a conceptual model of the psychosocial pathways linking socioeconomic status and body mass index (BMI) among smokers. Methods: A latent variable modeling approach was used to evaluate the interrelationships among socioeconomic status, perceived neighborhood disadvantage, social support, negative affect, and BMI among smokers recruited from the Houston metropolitan area (N = 424). Results: A total of 42.4% of participants were obese, with the highest prevalence of obesity among Latinos followed by African Americans. Across all racial/ethnic groups, perceived neighborhood disadvantage, social support, and negative affect functioned as pathways linking socioeconomic status and BMI. Conclusions: Findings indicate the need for interventions that target obesity among socioeconomically disadvantaged smokers and provide potential intervention targets for the prevention and treatment of obesity.

Objectives. We examined associations between health literacy and predictors of smoking cessation among 402 low-socioeconomic status (SES), racially/ethnically diverse smokers. Methods. Data were collected as part of a larger study evaluating smoking health risk messages. We conducted multiple linear regression analyses to examine relations between health literacy and predictors of smoking cessation (i.e., nicotine dependence, smoking outcome expectancies, smoking risk perceptions and knowledge, self-efficacy, intentions to quit or reduce smoking). Results. Lower health literacy was associated with higher nicotine dependence, more positive and less negative smoking outcome expectancies, less knowledge about smoking health risks, and lower risk perceptions. Associations remained significant (P < .05) after controlling for demographics and SES-related factors. Conclusions. These results provide the first evidence that low health literacy may serve as a critical and independent risk factor for poor cessation outcomes among low-socioeconomic status, racially/ethnically diverse smokers. Research is needed to investigate potential mechanisms underlying this relationship. [ABSTRACT FROM AUTHOR]

Objectives: To examine whether health locus of control mediated relations of self-reported neighborhood vigilance and biochemically verified, continuous short-term smoking abstinence among 200 smokers enrolled in a cohort study. Methods: A nonparametric bootstrapping procedure was used to assess mediation. Results: Health locus of control-chance mediated relations between neighbor­hood vigilance and smoking abstinence in analyses adjusted for sociodemograph­ics and tobacco dependence (p < .05). Greater vigilance was associated with greater attributions that health was af­fected by chance, which was associated with a lower likelihood of smoking absti­nence. Conclusions: Results suggest that neighborhood perceptions influence resi­dents' attributions for health outcomes, which can affect smoking abstinence. [ABSTRACT FROM AUTHOR]

Background: Smoking, poor diet, and physical inactivity account for as much as 60% of cancer risk. Latinos experience profound disparities in health behaviors, as well as the cancers associated with them. Currently, there is a dearth of controlled trials addressing these health behaviors among Latinos. Further, to the best of our knowledge, no studies address all three behaviors simultaneously, are culturally sensitive, and are guided by formative work with the target population. Latinos represent 14% of the U.S. population and are the fastest growing minority group in the country. Efforts to intervene on these important lifestyle factors among Latinos may accelerate the elimination of cancer-related health disparities. Methods/design: The proposed study will evaluate the efficacy of an evidence-based and theoretically-driven Motivation And Problem Solving (MAPS) intervention, adapted and culturally-tailored for reducing cancer risk related to smoking, poor diet, and physical inactivity among high-risk Mexican-origin smokers who are overweight/ obese (n = 400). Participants will be randomly assigned to one of two groups: Health Education (HE) or MAPS (HE + up to 18 MAPS counseling calls over 18 months). Primary outcomes are smoking status, servings of fruits and vegetables, and both self-reported and objectively measured physical activity. Outcome assessments will occur at baseline, 6 months, 12 months, and 18 months. Discussion: The current study will contribute to a very limited evidence base on multiple risk factor intervention studies on Mexican-origin individuals and has the potential to inform both future research and practice related to reducing cancer risk disparities. An effective program targeting multiple cancer risk behaviors modeled after chronic care programs has the potential to make a large public health impact because of the dearth of evidence-based interventions for Latinos and the extended period of support that is provided in such a program.

Objectives: To examine associations of the US and community subjective social status (SSS) ladders with smoking sta­tus, at-risk drinking, fruit and vegetable intake, physical activity, and body mass index among 1467 church-going African American adults from a larger cohort study. Methods: Regression analyses, adjusted for sociodemographics, exam­ined associations between SSS ladders and health behaviors. Results: The SSS-US ladder was significantly associated with fruit and vegetable consumption (p = .007) and physical activity (p = .005). The SSS-community ladder was not sig­nificantly associated with any health be­haviors. Conclusions: Among this sam­ple of African Americans, the SSS-US ladder is more predictive of some health behaviors than is the SSS-community ladder. [ABSTRACT FROM AUTHOR]

A mediation model explores the direct and indirect effects between an independent variable and a dependent variable by including other variables (or mediators). Mediation analysis has recently been used to dissect the direct and indirect effects of genetic variants on complex diseases using case-control studies. However, bias could arise in the estimations of the genetic variant-mediator association because the presence or absence of the mediator in the study samples is not sampled following the principles of case-control study design. In this case, the mediation analysis using data from case-control studies might lead to biased estimates of coefficients and indirect effects. In this article, we investigated a multiple-mediation model involving a three-path mediating effect through two mediators using case-control study data. We propose an approach to correct bias in coefficients and provide accurate estimates of the specific indirect effects. Our approach can also be used when the original case-control study is frequency matched on one of the mediators. We employed bootstrapping to assess the significance of indirect effects. We conducted simulation studies to investigate the performance of the proposed approach, and showed that it provides more accurate estimates of the indirect effects as well as the percent mediated than standard regressions. We then applied this approach to study the mediating effects of both smoking and chronic obstructive pulmonary disease (COPD) on the association between the CHRNA5-A3 gene locus and lung cancer risk using data from a lung cancer case-control study. The results showed that the genetic variant influences lung cancer risk indirectly through all three different pathways. The percent of genetic association mediated was 18.3% through smoking alone, 30.2% through COPD alone, and 20.6% through the path including both smoking and COPD, and the total genetic variant-lung cancer association explained by the two mediators was 69.1%.

Objective: Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Method: Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a bootstrapping procedure to test the indirect effects. Results" Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. Conclusions: The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, whereas affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse. [ABSTRACT FROM AUTHOR]

Chronic smoking is thought to cause changes in brain reward systems that result in overvaluation of cigarette-related stimuli and undervaluation of natural rewards. We tested the hypotheses that, in smokers, brain circuits involved in emotional processing: (i) would be more active during exposure to cigarette-related than neutral pictures; and (ii) would be less active to pleasant compared with cigarette-related pictures, suggesting a devaluation of intrinsically pleasant stimuli. We obtained whole-brain blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging data from 35 smokers during the presentation of pleasant (erotica and romance), unpleasant (mutilations and sad), neutral, and cigarette-related pictures. Whole-brain analyses showed significantly larger BOLD responses during presentation of cigarette-related pictures relative to neutral ones within the secondary visual areas, the cingulate gyrus, the frontal gyrus, the dorsal striatum, and the left insula. BOLD responses to erotic pictures exceeded responses to cigarette-related pictures in all clusters except the insula. Within the left insula we observed larger BOLD responses to cigarette-related pictures than to all other picture categories. By including intrinsically pleasant and unpleasant pictures in addition to neutral ones, we were able to conclude that the presentation of cigarette-related pictures activates brain areas supporting emotional processes, but we did not find evidence of overall reduced activation of the brain reward systems in the presence of intrinsically pleasant stimuli.

Background: The relationship between subjective social status (SSS), a person's perception of his/her relative position in the social hierarchy, and the ability to achieve long-term smoking abstinence during a specific quit attempt is unknown. The purpose of this study was to examine the relationship between SSS and long-term smoking abstinence among 421 racially/ethnically diverse smokers undergoing a specific quit attempt, as well as the interactive effects of race/ethnicity and sex. Methods: The main effects and moderated relationships of SSS on biochemically-confirmed, continuous smoking abstinence through 26 weeks post-quit were examined using continuation ratio logit models adjusted for sociodemographics and smoking characteristics. Results: Even after adjusting for the influence of socioeconomic status and other covariates, smokers endorsing lower SSS were significantly less likely to maintain long-term smoking abstinence during a specific quit attempt than those with higher SSS (OR = 1.14, 95% CI: 1.00 - 1.28; p = 0.044). The statistical significance of this relationship, however, did not vary by race/ethnicity or sex. Conclusions: SSS independently predicts long-term smoking abstinence during a specific quit attempt. SSS may be a useful screener to identify smokers at elevated risk of relapse who may require additional attention to facilitate long-term abstinence. More research is needed to understand the mechanisms underlying the relationship between SSS and long-term smoking abstinence in order to appropriately tailor treatment to facilitate abstinence among lower SSS smokers.

Introduction: The purpose of this study was to characterize the relationship between breast feeding and postpartum smoking abstinence among women who quit smoking due to pregnancy and who were participating in a randomized clinical trial of an intervention designed to prevent postpartum relapse. Methods: A total of 251 women were enrolled in the intervention between 30 and 33 weeks postpartum and were followed through 26 weeks postpartum. Participant characteristics were assessed at the prepartum baseline visit, any breast feeding was assessed at 8 weeks postpartum, and smoking abstinence was assessed at 8 and 26 weeks postpartum. Results: Although 79.1% of participants intended to breast feed, only 40.2% reported breast feeding at 8 weeks postpartum. Characteristics associated with breast feeding at 8 weeks postpartum included Caucasian race/ethnicity, greater education, higher household income, and being married/living with a significant other. Logistic regression analysis indicated that breast feeding at 8 weeks postpartum was significantly associated with smoking abstinence at 8 weeks postpartum, odds ratio (OR) = 7.27 (95% CI = 3.27, 16.13), p < .001. Breast feeding at 8 weeks postpartum was also associated with abstinence at 26 weeks postpartum after controlling for smoking status at 8 weeks postpartum, OR = 2.64 (95% CI = 1.14, 6.10), p = .02. Discussion: Encouraging breast feeding among women who quit smoking due to pregnancy may facilitate postpartum smoking abstinence while increasing adherence to current infant feeding guidelines.

Introduction:: The 68-item Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) is a theoretically derived measure of tobacco dependence consisting of 13 subscales measuring a variety of smoking motives. The WISDM-68 subscales have demonstrated good psychometric characteristics and have the potential to elucidate diverse nicotine dependence factors and mechanisms. The present research aimed to shorten the WISDM to reduce assessment burden while maintaining or enhancing its psychometric properties. [ABSTRACT FROM PUBLISHER]

Before starting a smoking cessation treatment, 51 smokers took part in a study aimed at investigating brain mechanisms associated with attention allocation. Event-related potentials to acoustic startle probes were recorded from 129 sensors during the presentation of neutral, pleasant, unpleasant, and cigarette-related pictures. Results indicated that the amplitude of the startle probe P3 component was reduced for pleasant, unpleasant, and cigarette-related conditions relative to neutral. Surface Laplacian estimates showed that sources of electrocortical activity under frontal and parietal sensors contributed to the modulation of this effect. For smokers, cigarette-related stimuli, like intrinsically motivating ones, capture attentional resources and therefore reduce the ability to process competing stimuli. The depletion of attentional resources in the presence of cigarette-related cues may contribute to the high relapse rate observed during attempts to quit smoking. [ABSTRACT FROM AUTHOR]

Objectives Direct and mediated associations between subjective social status (SSS), a subjective measure of socio-economic status, and smoking abstinence were examined during the period of acute withdrawal among a diverse sample of 421 smokers (33% Caucasian, 34% African American, 33% Latino) undergoing a quit attempt. Methods Logistic regressions examined relations between SSS and abstinence, controlling for socio-demographic variables. Depression, stress, positive affect and negative affect on the quit day were examined as potential affective mediators of the SSS-abstinence association, with and without adjusting for pre-quit mediator scores. Results SSS predicted abstinence to 2 weeks post-quit. Abstinence rates were 2.6 (postquit week 1) and 2.4 (postquit week 2) times higher in the highest versus the lowest SSS quartile. Depression and positive affect mediated the SSS–abstinence relationships, but only depression maintained significance when adjusting for the baseline mediator score. Conclusions Among a diverse sample of quitting smokers, low SSS predicted relapse during acute withdrawal after controlling for numerous covariates, an effect accounted for partially by quit day affective symptomatology. Smokers endorsing lower SSS face significant hurdles in achieving cessation, highlighting the need for targeted interventions encompassing attention to quit day mood reactivity.

Introduction:: Much of the existing research on smoking outcome expectancies has been guided by the Smoking Consequences Questionnaire (SCQ ). Although the original version of the SCQ has been modified over time for use in different populations, none of the existing versions have been evaluated for use among Spanish-speaking Latino smokers in the United States.

Introduction:: Although recent research indicates that many Latino smokers are nondaily smokers or daily smokers who smoke at a low level (≤5 cigarettes/day), almost no research has investigated the characteristics of low-level smokers because such individuals are typically excluded from clinical trial research.

This study explored some quandaries concerning craving and mood as motivators to smoke. Craving and negative mood have long been associated with day-to-day smoking as two of the primary motivational forces behind the maintenance of the behavior, as well as significant barriers in smokers' attempts to quit. Craving remains a clinically relevant phenomenon, with most smokers describing craving as a troublesome problem when quitting. Smokers' self-reports of negative mood, as an antecedent for smoking, are so robustly reported that many models of nicotine dependence have incorporated a critical role for negative mood in maintaining smoking behavior. However, several naturalistic studies that collected mood ratings with hand held computers from smokers in real time, just before smoking a cigarette, have provided scant evidence that negative mood plays a major role in motivation to smoke. No study to date has examined craving and mood data as a consequence of smoking, that is, collecting the same data immediately after smoking. This study used personal digital assistants (PDAs) to collect craving and mood data immediately before smoking, immediately after smoking, and at random times of day. Nontreatment seeking smokers (N=72) carried a PDA for an average of 10 days while they recorded their smoking behavior. Results showed that craving and negative mood ratings were lowest immediately after smoking compared with immediately before smoking and at random times of day. These findings suggest that smokers may be at least partially motivated to smoke to lower their craving and improve their mood states. [ABSTRACT FROM AUTHOR]

The article presents a study on depressed cigarette smokers undergoing withdrawals. The authors evaluated withdrawal in smokers with present treshold and subtreshold depressive disorders, who were participating in a pilot study of intensive counseling interventions for smoking stoppage. Almost all of the participants were taking antidepressants when they entered the trial. Findings suggest that within the idea of an intensive smoking cessation intervention, other smokers with current depressive disorders may experience improvement in affective and craving symptoms. Moreover, abstinence may be connected with the effect's improvement.

The authors' purpose of this portion of a 3-part review of interventions for tobacco dependence is to present evidence regarding the efficacy of behavioral treatments for smoking cessation. The present review includes evidence evaluated in the Treating Tobacco Use and Dependence Clinical Practice Guideline (the Guideline) (MC Fiore, WC Bailey, SJ Cohen, et al, 2000) as well as evidence published subsequent to the Guideline. A wide range of effective behavioral treatments for smoking cessation is available. These interventions come in a variety of formats and intensities, can be used by all types of clinicians in a variety of settings, and are appropriate for different types of smokers. The authors have organized recommendations in 2 broad domains that account for much of the variability across behavioral interventions, treatment content, and structure. Finally, the authors discuss key directions for future research. [ABSTRACT FROM AUTHOR]

Although converging lines of evidence suggest that nicotine and mood are related at a fundamental biological level, this link has not been reliably demonstrated in laboratory studies. In this study, startle probe methodology was used to examine the effects of nicotine administration and deprivation on emotional processes associated with motivation. Smokers ( N = 115) completed four laboratory sessions crossing deprivation (12‐hr deprived vs. nondeprived) with nicotine spray (active vs. placebo). Participants viewed affective pictures (positive, negative, neutral) and pictures involving cigarette cues, while startle probes were administered. Deprivation decreased startle responding to cigarette cues, suggesting an activation of appetitive processes. Nicotine administration suppressed overall startle responding during deprivation. In addition, during deprivation, random exposure to negative stimuli over two blocks of trials resulted in decreased adaptation of the startle response, suggesting that some sensitization to negative emotional cues may take place during nicotine withdrawal. These effects are consistent with formulations of addiction, stressing that withdrawal may both increase the reinforcement salience of smoking stimuli and decrease habituation to negative emotional stimuli.

Laboratory studies have demonstrated that cigarette smokers react with significant subjective and autonomic responses (e.g., increased craving and increased heart rate) in the presence of stimuli associated with smoking. Although cue reactivity effects are typically robust, a number of methodological considerations make interpretation and design of cue reactivity studies problematic. Previous research has paid scant attention to the psychometric properties of the cigarette cues presented, and standard cues would enhance comparison and synthesis of studies. In the present study, we evaluated 12 cigarette photos (compared with positive, negative, and neutral photos), used in a separate study, for their ability to evoke self‐report of craving in both nicotine‐deprived and nondeprived smokers. These photos performed as expected, with cigarette pictures evoking significantly higher craving than neutral pictures and deprived smokers showing a trend toward higher craving than nondeprived smokers. The cigarette picture set was evaluated for internal consistency (Cronbach's α = .97) as a 12‐item scale and further reduced to multiple 2‐item scales with reliability estimates ranging from .70 to .93. A cluster analysis of all pictures showed that, when rated for craving, cigarette pictures clustered together, indicating they had distinct properties compared with positive, negative, and neutral pictures. Effect sizes were calculated for each cigarette picture in both deprived and nondeprived smokers. The craving effect sizes ranged from .57 to .98 for nondeprived smokers, and from .61 to .99 for deprived smokers. The analyses suggest these cigarette pictures have excellent psychometric properties for use in future cue reactivity studies. [ABSTRACT FROM AUTHOR]

Racial/ethnic differences in the determinants of smoking cessation could have important treatment implications. The current study examined racial/ethnic differences in smoking cessation, prospective predictors of cessation, and whether the predictive ability of these factors differed by race/ethnicity. Participants were 709 employed adults recruited through the National Rural Electric Co-op Association or through natural gas pipeline corporations. Data were collected in 1990 and 1994. Although race/ethnicity was not predictive of abstinence, Hispanic, African American, and White smokers displayed differential on tobacco-, alcohol-, and work-related variables. These racial/ethnic differences highlight the specific factors that should be considered when providing smoking cessation treatment to specific populations. Limitations are noted.

The current study examined the association between education level and smoking status in a community-based sample of working adults. Participants were enrolled at the University of Texas M.D. Anderson Cancer Center site of a cancer risk behavior reduction intervention delivered at the worksite. There was a strong educational gradient in smoking status. The prevalence of current smoking was almost threefold higher among individuals with

Experimental and occasional cigarette use among college students is widespread. Little is known about what differentiates the occasional college smoker who becomes a regular smoker from the one who does not. Possible risk factors include peer smoking, lifestyle factors, such as lack of exercise, and health/addiction concerns. The current study investigated the progression of smoking in a cohort of 321 low-level/occasional smokers. Over the course of 4 years, 45% of low-level/occasional users had become nonsmokers, 35% became occasional smokers, and 20% became daily smokers. Baseline exercise patterns, addiction beliefs, and smoking pervasiveness were modestly related to distal smoking outcome. The level of baseline smoking was strongly related to smoking outcome. These results support the wisdom of limiting access and exposure to cigarettes among the college population. [Copyright &y& Elsevier]

Background. Relapse remains the most refractory aspect of nicotine dependence, but little is known about relapse that occurs after a period of prolonged abstinence (i.e., “late relapse”).Method. The current study examined the prevalence and predictors of late relapse/sustained abstinence in a community-based, longitudinal cohort of former smokers surveyed at baseline and again 4 years later (n = 1143).Results. Late relapse rates declined precipitously and sustained abstinence increased as the duration of abstinence at baseline increased. Although the risk for late relapse appeared to be small when using a point prevalence definition of smoking, that risk increased substantially if fluctuations in smoking behavior over time were considered (i.e., many former smokers relapsed and then regained abstinence during the 4-year study period). Although there were a number of significant prospective predictors of late relapse/sustained abstinence, they did not retain their predictive ability after controlling for baseline duration of abstinence.Conclusion. Although late relapse rates in the general population of former smokers appear low, and particularly so for individuals who have been abstinent for long periods of time, fluctuations between abstinence and smoking over time are not uncommon. How these fluctuations influence health or sustained abstinence over time is unclear. Because late relapse rates are generally low, interventions are likely to require careful targeting of at-risk individuals if they are to be efficacious and cost-effective. [Copyright &y& Elsevier]
