Lower health literacy predicts smoking relapse among racially/ethnically diverse smokers with low socioeconomic status.

BACKGROUND: Nearly half of U.S. adults have difficulties with health literacy (HL), which is defined as the ability to adequately obtain, process, and understand basic health information. Lower HL is associated with negative health behaviors and poor health outcomes. Racial/ethnic minorities and those with low socioeconomic status (SES) are disproportionately affected by poor HL. They also have higher smoking prevalence and more difficulty quitting smoking. Thus, lower HL may be uniquely associated with poorer cessation outcomes in this population. METHODS: This study investigated the association between HL and smoking cessation outcomes among 200, low-SES, racially/ethnically diverse smokers enrolled in smoking cessation treatment. Logistic regression analyses adjusted for demographics (i.e., age, gender, race/ethnicity, relationship status), SES-related characteristics (i.e., education, income), and nicotine dependence were conducted to investigate associations between HL and smoking relapse at the end of treatment (3 weeks post quit day). RESULTS: Results indicated that smokers with lower HL (score of < 64.5 on the Rapid Estimate of Adult Literacy in Medicine [REALM]) were significantly more likely than those with higher HL (score of ≥ 64.5 on the REALM) to relapse by the end of treatment, even after controlling for established predictors of cessation including demographics, SES, and nicotine dependence (OR = 3.26; 95% CI = 1.14, 9.26). CONCLUSIONS: Findings suggest that lower HL may serve as an independent risk factor for smoking relapse among low-SES, racially/ethnically diverse smokers enrolled in treatment. Future research is needed to investigate longitudinal relations between HL and cessation outcomes and potential mechanisms of this relationship.

The association of depression and anxiety with glycemic control among Mexican Americans with diabetes living near the U.S.-Mexico border.

BACKGROUND: The prevalence of diabetes is alarmingly high among Mexican American adults residing near the U.S.-Mexico border. Depression is also common among Mexican Americans with diabetes, and may have a negative influence on diabetes management. Thus, the purpose of the current study was to evaluate the associations of depression and anxiety with the behavioral management of diabetes and glycemic control among Mexican American adults living near the border. METHODS: The characteristics of Mexican Americans with diabetes living in Brownsville, TX (N = 492) were compared by depression/anxiety status. Linear regression models were conducted to evaluate the associations of depression and anxiety with BMI, waist circumference, physical activity, fasting glucose, and glycated hemoglobin (HbA1c). RESULTS: Participants with clinically significant depression and/or anxiety were of greater age, predominantly female, less educated, more likely to have been diagnosed with diabetes, and more likely to be taking diabetes medications than those without depression or anxiety. In addition, anxious participants were more likely than those without anxiety to have been born in Mexico and to prefer study assessments in Spanish rather than English. Greater depression and anxiety were associated with poorer behavioral management of diabetes (i.e., greater BMI and waist circumference; engaging in less physical activity) and poorer glycemic control (i.e., higher fasting glucose, HbA1c). CONCLUSIONS: Overall, depression and anxiety appear to be linked with poorer behavioral management of diabetes and glycemic control. Findings highlight the need for comprehensive interventions along the border which target depression and anxiety in conjunction with diabetes management.

Social support mediates the association of health literacy and depression among racially/ethnically diverse smokers with low socioeconomic status.

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.

Psychosocial predictors of weight regain in the weight loss maintenance trial.

This study's purpose was to identify psychosocial predictors of weight loss maintenance in a multi-site clinical trial, following a group-based weight loss program. Participants (N = 1025) were predominately women (63%) and 38% were Black (mean age = 55.6 years; SD = 8.7). At 12 months, higher SF-36 mental health composite scores were associated with less weight regain (p < .01). For Black participants, an interaction existed between race and friends' encouragement for exercise, where higher exercise encouragement was related to more weight regain (p < .05). At 30 months, friends' encouragement for healthy eating was associated with more weight regain (p < .05), whereas higher SF-36 mental health composite scores were related to less weight regain (p < .0001). Perceived stress and select health-related quality of life indices were associated with weight regain; this relationship varied across gender, race, and treatment conditions. Temporal changes in these variables should be investigated for their impact on weight maintenance.

Associations between health literacy and established predictors of smoking cessation.

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.

Race moderates the effect of menthol cigarette use on short-term smoking abstinence.

INTRODUCTION: The Food and Drug Administration is in the process of reviewing evidence of the impact of mentholated cigarettes on smoking behaviors and smoking cessation in order to determine if these products should be removed from the market. More empirical research is needed to inform those decisions. The goal of this study was to examine associations of menthol cigarette use with biochemically verified continuous short-term smoking abstinence, and potential moderation by race, among adult current smokers enrolled in a cohort study (N = 183; 57.4% female; 48.1% non-Hispanic Black, 51.9% non-Hispanic White). METHODS: Continuation ratio logit models, adjusted for age, race, gender, total annual household income, educational level, employment status, and partner status, were used to examine associations of menthol use with smoking abstinence with and without an interaction term for race. RESULTS: Menthol cigarette use was not significantly associated with smoking abstinence in the sample as a whole; however, there was a significant interaction of menthol use with race (p = .03). Follow-up analyses stratified by race indicated that among White participants, menthol users had significantly lower odds of maintaining continuous abstinence than nonmenthol users (p = .05). Exploratory analyses suggested that tobacco dependence may lie along the causal pathway and partially explain this effect. CONCLUSIONS: White menthol smokers in this sample were at increased risk of smoking relapse relative to White nonmenthol smokers, at least partially due to greater tobacco dependence. Results should be replicated among other treatment-seeking samples with a greater representation of White menthol and Black nonmenthol smokers.

Directive support, nondirective support, and health behaviors in a community sample.

Social support is associated with improved psychological functioning, physical health, and health-promoting behaviors. However, research suggests that health outcomes might depend upon the type rather than the amount of support provided to recipients. This study assessed the relationship among nondirective and directive support, and health behaviors (i.e., physical activity, fruit and vegetable intake, alcohol use) in a community sample of 304 adults. Results revealed that nondirective support was related to greater fruit and vegetable intake and lower alcohol use; directive support was not associated with these behaviors. For physical activity, a similar trend emerged, but support variables did not explain any variance above that explained by demographic variables. These findings offer a unique contribution to the literature, as they suggest that certain types of supportive behaviors are important in encouraging positive health behaviors.

Smoking, depression, and gender in low-income African Americans with HIV/AIDS.

Individuals with HIV/AIDS have disproportionately high depression and smoking prevalence rates. Smokers with HIV/AIDS are more susceptible to opportunistic infections, smoking-related illnesses, and mortality. African Americans (AAs) comprise nearly half of newly diagnosed HIV+ cases. We examined the relationship among smoking, depression, and gender in un- or under-insured AA patients (N = 289) at an urban community HIV/AIDS clinic in the southeastern US. Approximately 33% met criteria for a depressive disorder and 37% endorsed current smoking status. Men were more likely than women to be current smokers and depressed participants were more likely to smoke than non-depressed participants. Women had significantly higher rates of depression compared to men. Both depression and male gender independently predicted current smoking status. Depression and smoking are likely to co-occur in HIV/AIDS patients; however, standard smoking cessation interventions often exclude smokers with comorbid psychiatric and/or medical illnesses. Interventions addressing these comorbidities are warranted.

Cigarette smoking across the schizotypy spectrum.

This study examined relationships between schizotypy symptom dimensions and smoking. Individuals with schizotypy (n=81) were twice as likely to smoke as individuals in a normative reference group (n=303). Among those with schizotypy, smokers reported more severe disorganization and less severe negative schizotypal symptoms. These findings offer insight into mechanisms underlying smoking in schizotypal individuals and suggest areas for further research.

Support needs of overweight African American women for weight loss.

OBJECTIVES: To examine social support needs of obese and overweight African American women for weight loss. METHODS: Focus groups were conducted with overweight and obese African American women. Data were analyzed using standard grounded theory text analysis. RESULTS: Our middle-aged (45.7 years; SD = 12.6) women (N = 66) were interested in receiving support from others focused on the health benefits of weight loss. Behaviors perceived as supportive include co-participating in exercise, providing nutrition education, using positive reinforcements, and avoiding criticism. CONCLUSIONS: African American women are interested in a program designed to increase social support for their weight loss.

Nonjudging facet of mindfulness predicts enhanced smoking cessation in Hispanics.

Although most smokers express interest in quitting, actual quit rates are low. Identifying strategies to enhance smoking cessation is critical, particularly among underserved populations, including Hispanics, for whom many of the leading causes of death are related to smoking. Mindfulness (purposeful, nonjudgmental attention to the present moment) has been linked to increased likelihood of cessation. Given that mindfulness is multifaceted, determining which aspects of mindfulness predict cessation could help to inform interventions. This study examined whether facets of mindfulness predict cessation in 199 Spanish-speaking smokers of Mexican heritage (63.3% male, mean age of 39 years, 77.9% with a high school education or less) receiving smoking cessation treatment. Primary outcomes were 7-day abstinence at weeks 3 and 26 postquit (biochemically confirmed and determined using an intent-to-treat approach). Logistic random coefficient regression models were utilized to examine the relationship between mindfulness facets and abstinence over time. Independent variables were subscales of the Five Facet Mindfulness Questionnaire (Observing, Describing, Acting With Awareness, Nonjudging, and Nonreactivity). The Nonjudging subscale (i.e., accepting thoughts and feelings without evaluating them) uniquely predicted better odds of abstinence up to 26 weeks postquit. This is the first known study to examine whether specific facets of mindfulness predict smoking cessation. The ability to experience thoughts, emotions, and withdrawal symptoms without judging them may be critical in the process of quitting smoking. Results indicate potential benefits of mindfulness among smokers of Mexican heritage and suggest that smoking cessation interventions might be enhanced by central focus on the Nonjudging aspect of mindfulness.

Adaptation of a counseling intervention to address multiple cancer risk factors among overweight/obese Latino smokers.

More than 60% of cancer-related deaths in the United States are attributable to tobacco use, poor nutrition, and physical inactivity, and these risk factors tend to cluster together. Thus, strategies for cancer risk reduction would benefit from addressing multiple health risk behaviors. We adapted an evidence-based intervention grounded in social cognitive theory and principles of motivational interviewing originally developed for smoking cessation to also address physical activity and fruit/vegetable consumption among Latinos exhibiting multiple health risk behaviors. Literature reviews, focus groups, expert consultation, pretesting, and pilot testing were used to inform adaptation decisions. We identified common mechanisms underlying change in smoking, physical activity, and diet used as treatment targets; identified practical models of patient-centered cross-cultural service provision; and identified that family preferences and support as particularly strong concerns among the priority population. Adaptations made to the original intervention are described. The current study is a practical example of how an intervention can be adapted to maximize relevance and acceptability and also maintain the core elements of the original evidence-based intervention. The intervention has significant potential to influence cancer prevention efforts among Latinos in the United States and is being evaluated in a sample of 400 Latino overweight/obese smokers.

Testing a Moderated Mediation Model of Mindfulness, Psychosocial Stress, and Alcohol Use among African American Smokers.

Mindfulness-based strategies have received empirical support for improving coping with stress and reducing alcohol use. The present study presents a moderated mediation model to explain how mindfulness might promote healthier drinking patterns. This model posits that mindfulness reduces perceived stress, leading to less alcohol use, and also weakens the linkage between stress and alcohol use. African American smokers (N = 399, 51% female, Mage = 42) completed measures of dispositional mindfulness, perceived stress, quantity of alcohol use, frequency of binge drinking, and alcohol use disorder symptoms. Participants with higher levels of dispositional mindfulness reported less psychosocial stress and lower alcohol use on all measures. Furthermore, mindfulness moderated the relationship between perceived stress and quantity of alcohol consumption. Specifically, higher perceived stress was associated with increased alcohol use among participants low, but not high, in mindfulness. Mindfulness may be one strategy to reduce perceived stress and associated alcohol use among African American smokers.

Mindfulness Ameliorates the Relationship between Weight Concerns and Smoking Behavior in Female Smokers: A Cross-Sectional Investigation.

Weight concerns are common among female smokers and may interfere with smoking cessation. It is imperative to identify protective factors to lessen the likelihood that smoking-related weight concerns prompt smoking and hinder cessation efforts. Mindfulness is one potential protective factor that might prevent weight concerns from triggering smoking. In the current study, relationships among facets of trait mindfulness, smoking-related weight concerns, and smoking behavior were examined among 112 young adult female smokers (70.5% daily smokers; 83% Caucasian; mean age 20 [SD = 1.69]). After controlling for demographic variables, the Describing facet of trait mindfulness predicted lower smoking-related weight concerns. The mindfulness characteristics of Acting with Awareness, Nonreactivity, and Describing moderated the relationship between smoking-related weight concerns and smoking frequency, such that smoking-related weight concerns predicted greater smoking frequency in female smokers with low and medium levels of these mindfulness characteristics but did not in those with higher levels of mindfulness. These results suggest that mindfulness-based interventions may be effective for weight-concerned smokers.

Positive smoking outcome expectancies mediate the association between negative affect and smoking urge among women during a quit attempt.

Ecological momentary assessment was used to examine associations between negative affect, positive smoking outcome expectancies, and smoking urge during the first 7 days of a smoking quit attempt. Participants were 302 female smokers who enrolled in an individually tailored smoking cessation treatment study. Multilevel mediation analysis was used to examine the temporal relationship among the following: (a) the effects of negative affect and positive smoking outcome expectancies at 1 assessment point (e.g., time j) on smoking urge at the subsequent time point (e.g., time j + 1) in Model 1; and, (b) the effects of negative affect and smoking urge at time j on positive smoking outcome expectancies at time j + 1 in Model 2. The results from Model 1 showed a statistically significant effect of negative affect at time j on smoking urge at time j + 1, and this effect was mediated by positive smoking outcome expectancies at time j, both within- and between-participants. In Model 2, the within-participant indirect effect of negative affect at time j on positive smoking outcome expectancies at time j + 1 through smoking urge at time j was nonsignificant. However, a statistically significant indirect between-participants effect was found in Model 2. The findings support the hypothesis that urge and positive smoking outcome expectancies increase as a function of negative affect, and suggest a stronger effect of expectancies on urge as opposed to the effect of urge on expectancies.

Mindfulness predicts lower affective volatility among African Americans during smoking cessation.

Recent research suggests that mindfulness benefits emotion regulation and smoking cessation. However, the mechanisms by which mindfulness affects emotional and behavioral functioning are unclear. One potential mechanism, lower affective volatility, has not been empirically tested during smoking cessation. This study examined longitudinal associations among mindfulness and emotional responding over the course of smoking cessation treatment among predominantly low-socioeconomic status (SES) African American smokers, who are at high risk for relapse to smoking and tobacco-related health disparities. Participants (N = 399, 51% female, mean age = 42, 48% with annual income <$10,000) completed a baseline measure of trait mindfulness. Negative affect, positive affect, and depressive symptoms were assessed at five time points during smoking cessation treatment (up to 31 days postquit). Volatility indices were calculated to quantify within-person instability of emotional symptoms over time. Over and above demographic characteristics, nicotine dependence, and abstinence status, greater baseline trait mindfulness predicted lower volatility of negative affect and depressive symptoms surrounding the quit attempt and up to 1 month postquit, ps < 0.05. Although volatility did not mediate the association between greater mindfulness and smoking cessation, these results are the first to show that mindfulness is linked to lower affective volatility (or greater stability) of negative emotions during the course of smoking cessation. The present study suggests that mindfulness is linked to greater emotional stability and augments the study of mindfulness in diverse populations. Future studies should examine the effects of mindfulness-based interventions on volatility and whether lower volatility explains effects of mindfulness-based treatments on smoking cessation.

Smoking topography and outcome expectancies among individuals with schizotypy.

Compared to smokers in the general population, smokers with schizophrenia smoke more cigarettes per day and have higher nicotine dependence and biochemical indicators of nicotine intake. They also have more intense smoking topography and greater positive smoking expectancies. Little is known about the relationship between smoking and schizotypy, defined as the personality organization reflecting a vulnerability to schizophrenia-spectrum pathology. This study assessed schizotypy symptoms, smoking characteristics and behaviors, and smoking expectancies in young adults with psychometrically defined schizotypy and demographically matched controls without schizotypy. Smokers with schizotypy had higher nicotine dependence and smoked more cigarettes per week compared to control smokers. They were also more likely to endorse greater positive consequences (i.e., improved state enhancement, stimulation, social facilitation, taste/sensorimotor manipulation, reduced negative affect and boredom) and fewer negative consequences of smoking. Smokers with schizotypy and control smokers did not differ on smoking topography or carbon monoxide levels. This is the first known study to investigate relationships between these smoking-related variables in smokers with schizotypy. Individuals with schizotypy possessed certain smoking-related characteristics and smoking expectancies similar to those with schizophrenia. This offers preliminary insight into unique smoking-related factors among individuals with schizotypy and highlights the importance of continued research in this area.

Medication-taking beliefs and diabetes in American Samoa: a qualitative inquiry.

In American Samoa (AS), nearly 22% of adults have type 2 diabetes. Diabetes is best managed by diet and lifestyle modifications and strict medication adherence. Cultural aspects might affect medication-taking beliefs, and thereby influence medication adherence. This study aims to explore diabetes medication-taking experiences and knowledge and related cultural beliefs in AS adults with diabetes and healthcare providers. Six focus groups were conducted with 39 AS adults with diabetes and individual interviews were performed with 13 diabetes healthcare providers. Data were transcribed and analyzed using NVivo 8 software. Themes pertaining to medication taking and adherence were identified. Patients and providers reported that barriers such as confusion about medications and concern about medication costs negatively influence medication taking, while cultural values and obligations both positively and negatively impact medication adherence. These findings help elucidate the relationship between medication-taking beliefs and culture in AS adults with diabetes and highlight the importance of continued research within this population.

Lifestyle and cancer prevention in women: knowledge, perceptions, and compliance with recommended guidelines.

BACKGROUND: Most women in the United States do not meet minimum recommendations for physical activity or fruit/vegetable consumption. Thus, many are overweight/obese and are at increased risk for cancer morbidity and mortality. This study investigated women's perceptions about the importance of physical activity and a healthy diet in preventing cancer, perceptions of engaging in these behaviors, and whether or not the behaviors met cancer prevention recommendations. METHOD: A cross-sectional, national, random-digit-dialed telephone survey was conducted with 800 women, ages 18 and older. The response rate was 24.5%. Measures assessed demographics, perceived health status, beliefs about the role of physical activity and diet in cancer prevention, perceived engagement in these behaviors, and actual behaviors. RESULTS: Only 9.9% of women who reported eating a healthy diet met minimum fruit and vegetable recommendations; 39.7% of women who reported regular physical activity met the minimum recommendation. Analyses adjusted for demographics indicated that low education was associated with reporting regular physical activity to prevent cancer, yet failing to meet the minimum recommendation (odds ratio [OR]=0.90, 95% confidence interval [CI]: 0.82-0.98, p=0.01). Racial/ethnic minority status was marginally significantly associated with reporting eating a healthy diet to prevent cancer, yet failing to consume sufficient fruits and vegetables (OR=2.94, 95% CI: 0.99-8.71, p=0.05). CONCLUSIONS: Most women who reported eating a healthy diet and being physically active to prevent cancer failed to meet the minimum cancer prevention recommendations. Furthermore, low socioeconomic status and racial/ethnic minority women may be particularly vulnerable to discrepancies between beliefs and behavior.

Cluster analysis of undergraduate drinkers based on alcohol expectancy scores.

OBJECTIVE: Expectancies of alcohol's effects have been associated with problem drinking in undergraduates. If subgroups can be classified based on expectancies, this may facilitate identifying those at highest risk for problem drinking. METHOD: Undergraduates (N = 612) from two state universities completed a web-based survey. Responses to the Comprehensive Effects of Alcohol scale were analyzed using k-means cluster analysis separately within each university sample. RESULTS: Hartigan's heuristic was used to determine that five was the optimal number of clusters in each sample. Clusters were distinguishable based on their overall magnitude of expectancy endorsement and by a tendency to endorse stronger positive than negative expectancies. Subsequent analyses were conducted to compare clusters on alcohol involvement and trait disinhibition. A cluster characterized by endorsement of positive and negative expectancies ("strong expectancy") was associated with a particularly problematic risk profile, specifically concerning difficulties with self-control (i.e., trait disinhibition and impaired control over alcohol use). A cluster with higher positive and lower negative expectancies reported frequent heavy drinking but appeared to be at lower risk than the strong expectancy cluster in a number of respects. Negative expectancy endorsement appeared to represent added risk above and beyond positive expectancies. CONCLUSIONS: Results suggest that both the magnitude and combination of expectancies endorsed by subgroups of undergraduate drinkers may relate to their risk level in terms of alcohol involvement and personality traits. These findings may have implications for interventions with young adult drinkers.
