Effects of culturally specific cessation messages on theoretical antecedents of behavior among low-income african american smokers.

Previous research has highlighted the importance of cultural relevance in health risk communications, including tobacco interventions. However, few studies have examined the active components of smoking cessation messages targeting low-income African American smokers. This study tested the influence of message content and culturally specific framing in a sample of adult smokers. In a 2 × 2 factorial experiment, 243 African American smokers (M = 19 cigarettes/day) recruited from the community (55% women; mean age = 43 years) were randomly assigned to 1 of 4 conditions: culturally specific smoking messages, standard smoking messages, culturally specific exercise/weight messages, or standard exercise/weight messages. The primary outcome measures were theoretical antecedents to behavior change, including risk perceptions (general, personal, and culturally specific), readiness to quit smoking, and smoking-related knowledge. The results showed that the smoking messages produced greater culturally specific risk perceptions, readiness to quit smoking, and smoking-related knowledge. The culturally specific messages produced greater personal risk perceptions and intentions to quit. Culturally specific risk perceptions were most affected by culturally specific smoking messages. Findings support the roles of message content and culturally specific framing in the efficacy of brief written interventions for smoking cessation in this population. Future research is needed to examine the influence of these constructs on behavior change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Moderate intensity exercise as an adjunct to standard smoking cessation treatment for women: A pilot study.

Previous randomized controlled trials have not supported moderate intensity exercise as an efficacious adjunct to smoking cessation treatments for women; however, compliance with exercise programs in these studies has been poor. The purpose of this pilot study was to estimate the effects of moderate intensity exercise on smoking cessation outcomes under optimal conditions for exercise program compliance. Sixty previously sedentary, healthy, female smokers were randomized to an 8-week program consisting of brief baseline smoking cessation counseling and the nicotine patch plus either 150 min/week of moderate intensity exercise or contact control. Participants attended a median of 86.4% and 95.5% of prescribed exercise/control sessions, respectively. There was a moderate, though statistically nonsignificant, effect of exercise at post-treatment for objectively verified 7-day point prevalence abstinence (48.3% vs. 23.3%; OR = 3.07, 95% CI: 0.89–11.07) and prolonged abstinence (34.5% vs. 20.0%; OR = 2.11, 95% CI: 0.56–8.32). Effects were attenuated when controlling for potential confounders, and after a 1-month, no-treatment period. The findings provide a preliminary indication that, given adequate compliance, moderate intensity exercise may enhance short-term smoking cessation outcomes for women; however, a larger trial is warranted.

Affective benefits of exercise while quitting smoking: Influence of smoking-specific weight concern.

The present study aimed to shed light on contradictory findings about the effects of exercise on negative affect during smoking cessation. The authors hypothesized that smoking-specific weight concern would moderate the relationship between exercise and negative affect. Baseline measures of smoking-specific weight concern, exercise, and negative affect were completed by 146 women participating in a randomized controlled trial of smoking cessation plus weight control. Exercise and negative affect were reassessed 1 week after the quit date. Among women with heightened smoking-specific weight concern, greater engagement in exercise was associated with less of an increase in negative affect. Results suggest that exercise may help temper negative affect states for women with heightened smoking-specific weight concern. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A systematic review of evidence for the appropriateness of neonatal screening programmes for inborn errors of metabolism

The nicotinic antagonist mecamylamine was evaluated in a randomized smoking cessation trial. Four groups of participants (n = 20 per group) received nicotine plus mecamylamine, nicotine alone, mecamylamine alone, or no drug for 4 weeks before cessation. After the quit-smoking date, all subjects received nicotine plus mecamylamine treatment for 6 weeks. Nicotine skin patches (21 mg/24 hr) and mecamylamine capsules (2.5-5.0 mg twice per day) were used. Precessation mecamylamine significantly prolonged the duration of continuous smoking abstinence; abstinence rates at the end of treatment were 47.5% with mecamylamine and 27.5% without mecamylamine. Nicotine + mecamylamine reduced ad lib smoking, smoking satisfaction, and craving more than either drug alone. Moreover, the orthostatic decrease in blood pressure caused by mecamylamine was offset by nicotine. Mecamylamine before smoking cessation may be an effective adjunct to nicotine patch therapy.     

Depressive symptoms and readiness to quit smoking among cigarette smokers in outpatient alcohol treatment.

The authors examined whether length of alcohol abstinence and depressive symptoms were related to motivational readiness to consider smoking cessation among patients in alcohol treatment. Participants were adults (N = 253) enrolled in a smoking cessation trial. Controlling for gender, depressive symptoms, and nicotine dependence, hierarchical regression analysis of readiness scores revealed a significant interaction of days since last drink and depressive symptoms. It was found that a greater number of days since last drink was associated with greater readiness, but only among patients with low scores on the Center for Epidemiologic Studies Depression Scale (L. S. Radloff, 1977). The findings suggest that alcoholic smokers with low depressive symptoms are more receptive to quitting smoking after sustained alcohol abstinence.

Evaluating initial reach and robustness of a practical randomized trial of smoking reduction.

Objective: This study evaluated the reach, initial effectiveness, and potential moderators and mediators of results of a smoking reduction program. Design: A generally representative sample of 320 adult smokers from an HMO, scheduled for outpatient surgery or a diagnostic procedure, were randomized to enhanced usual care or a theory-based smoking reduction intervention that combined telephone counseling and tailored newsletters. Main Outcome Measures: Self-reported number of cigarettes smoked and carbon monoxide levels. Results: The intervention enrolled 30% of known eligible smokers and produced reductions of 3 cigarettes per day greater than enhanced usual care. Intervention participants were significantly more likely than control participants to achieve at least a 50% reduction in self-reported number of cigarettes using complete cases, imputation analyses, and intent-to-treat procedures. Similar patterns were seen for carbon monoxide results but were significant only in complete case analyses. The intervention was generally robust across patient characteristics (e.g., education, ethnicity, health literacy, and dependence) and phone counselors. Conclusion: Initial results suggest that this program has potential to reach and assist smokers who may not participate in cessation programs. Additional research is indicated to enhance intervention effects, assess maintenance, and evaluate public health impact. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The nicotine patch in smoking cessation. A randomized trial with telephone counseling

BACKGROUND: This study was conducted to determine the efficacy of the nicotine patch in smoking cessation when combined with self-help materials, three brief visits, and telephone counseling. METHODS: One hundred fifty-nine healthy volunteers who smoked at least one pack of cigarettes per day and desired to quit smoking were enrolled in a double-blind trial with 6-week treatment and 6-month follow-up periods. After review of self-help materials, subjects were randomly assigned to regimens of nicotine or placebo patches. Subjects wore two patches per day for 4 weeks (25 mg of nicotine per 24 hours), then one patch per day for 2 weeks. Return visits were at the ends of weeks 4 and 6. Telephone counseling was given during weeks 1, 2, 3, and 5. Abstinence at 6 weeks was defined as zero cigarettes smoked for the previous 28 days, verified by exhaled carbon monoxide less than 8 ppm at 4 weeks and 6 weeks. Abstinence at 3 and 6 months was defined as self-report of zero cigarettes since the previous contact, verified by carbon monoxide value at 6 months. RESULTS: Abstinence rates at 6 weeks, 3 months, and 6 months were 29.5%, 21.8%, and 20.5% in the active group, and 8.8%, 3.8%, and 2.5% in the placebo group (P < or = .001 for each comparison), respectively. Skin irritation was the main side effect, causing 1.3% to drop out. CONCLUSION: The nicotine patch is efficacious in smoking cessation over a 6-month period, when combined with only self-help materials, three brief visits, and telephone counseling.     

Nicotine–mecamylamine treatment for smoking cessation: The role of pre-cessation therapy.

The nicotinic antagonist mecamylamine was evaluated in a randomized smoking cessation trial. Four groups of participants (n?=?20 per group) received nicotine plus mecamylamine, nicotine alone, mecamylamine alone, or no drug for 4 weeks before cessation. After the quit-smoking date, all subjects received nicotine plus mecamylamine treatment for 6 weeks. Nicotine skin patches (21 mg/24 hr) and mecamylamine capsules (2.5–5.0 mg twice per day) were used. Precessation mecamylamine significantly prolonged the duration of continuous smoking abstinence; abstinence rates at the end of treatment were 47.5% with mecamylamine and 27.5% without mecamylamine. Nicotine + mecamylamine reduced ad lib smoking, smoking satisfaction, and craving more than either drug alone. Moreover, the orthostatic decrease in blood pressure caused by mecamylamine was offset by nicotine. Mecamylamine before smoking cessation may be an effective adjunct to nicotine patch therapy.

Assessing motivational readiness and decision making for exercise.

Investigated motivational and cognitive processes of behavior change in the area of exercise adoption. A total of 778 men and women, recruited from 4 worksites, answered a 40-item questionnaire based on constructs from the transtheoretical model of behavior change. Principal-components analysis identified 2 factors: avoidance of exercise (Cons) and positive perceptions of exercise (Pros). ANOVA showed that the Pros, Cons, and a Decisional Balance measure (Pros minus Cons) were significantly associated with stage of exercise adoption. Results are consistent with applications of the model to smoking cessation and other areas of behavior change. Distinctions between exercise adoption and behaviors such as smoking cessation, weight loss, and alcoholism are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Characteristics of smokers who attempt to quit and of those who recently succeeded

Although a high percentage of smokers attempt to quit each year, success rates are low. Thus, public health strategies must not only convince some smokers to attempt cessation, but also improve the success rate among other smokers already motivated to quit. Specific cessation strategies may be required for smokers in these two groups. This study compares sociodemographic and health behavior characteristics of smokers who have and have not attempted to quit and of those who recently succeeded. To determine whether these characteristics vary for men and women, we stratified analyses on gender. Data were obtained from random sample health surveys conducted 1981-1982 and 1983-1984 in two New England communities. Analyses include data on 2,086 respondents who reported smoking cigarettes in the previous year. Men and women were equally likely both to attempt cessation and to quit. Except for an inverse association with age, attempting to quit was not associated with sociodemographic variables. In men and women, attempts were associated with encouraging others to quit and attempting to increase exercise. Successful cessation attempts were associated with not living with a smoker in women; marital status, attempted weight loss, and increased age in men; and with efforts to increase exercise in both men and women. These characteristics could be useful in targeting smokers who attempt to quit, but fail. Improving the success rate in this group could greatly reduce smoking prevalence in the community.     

Regular smokers, lifetime very light smokers, and reduced smokers: Comparison of psychosocial and smoking characteristics in women.

This study compared stable very light smokers ([VLS]; less than 6 cigarettes a day) with regular smokers ([RS]; greater than 14 cigarettes a day) in a cohort of women followed up for 1 yr. The VLS showed evidence of inhaling the cigarette smoke. They were not novice smokers, nor were they under particular pressure to limit their smoking. Among the 61 VLS, 34 had at one time smoked more than 10 cigarettes per day. These "reduced smokers" were broadly similar to the lifetime VLS, who differed from RS in several important respects. In a multiple logistic regression, education and smoking patterns in relatives were independently associated with very light versus regular smoking. Familial factors and personal resources may protect against dependence among those who use tobacco. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Use of the University of Rhode Island Change Assessment to measure motivational readiness to change in psychiatric and dually diagnosed individuals.

In this report, the original 4-factor structure of the University of Rhode Island Change Assessment (URICA; C. C. DiClemente & S. O. Hughes, 1990) was replicated, and the scale's internal consistency was found to be acceptable in a sample of 120 psychiatric and dually diagnosed inpatient participants, who had participated in a randomized clinical trial comparing standard treatment (ST) and ST plus motivational interviewing. Contrary to the authors' hypotheses, participants classified as having low motivational readiness to change, based on their URICA scores, demonstrated greater treatment adherence than high-readiness participants, in that they attended a greater proportion of therapy groups while hospitalized (54% vs. 39%; p     

Dose-dependent induction of IL-12 but not IL-10 from human keratinocytes after exposure to ultraviolet light A

OBJECTIVE: Our purpose was to assess the risk of ectopic pregnancy among women who smoke cigarettes. STUDY DESIGN: We used data from a case-control study of ectopic pregnancy conducted from October 1988 to August 1990 at an inner-city hospital in Georgia. Cases were 196 non-Hispanic black women with a surgically confirmed ectopic pregnancy. Controls were non-Hispanic black women who had delivered either a live or a stillborn infant weighing at least 500 gm (n = 882) or who were pregnant and seeking an induced abortion (n = 237). RESULTS: After we adjusted for parity, douching history, history of infertility, and age, the odds ratio for ectopic pregnancy was 1.9 (95% confidence interval 1.4 to 2.7) for women who smoked during the periconception period compared with women who did not smoke at that time. After stratification by the amount of daily smoking during the periconception period, the odds ratio rose from 1.6 (95% confidence interval 0.9 to 2.9) for women who smoked 1 to 5 cigarettes to 1.7 (95% confidence interval 1.1 to 2.8) for women who smoked 6 to 10 cigarettes to 2.3 (95% confidence interval 1.3 to 4.0) for women who smoked 11 to 20 cigarettes, and to 3.5 (95% confidence interval 1.4 to 8.6) for women who smoked >20 cigarettes per day. CONCLUSION: In this inner-city population, cigarette smoking was an independent, dose-related risk factor for ectopic pregnancy among black women. The public health and medical care communities should inform the public of this additional risk associated with cigarette smoking and intensify intervention strategies to reduce cigarette smoking among women of reproductive age.     

The effects of platelet-derived growth factor-BB on healing of the rabbit medial collateral ligament. An in vivo study

Cigarette smoking poses significant risk to mother and infant during pregnancy and the postpartum period. Recruitment of pregnant smokers to intervention studies has often been reactive and has excluded certain subgroups of women, such as those who have recently quit smoking. In this study, we examined smoking patterns among a proactively recruited sample of women presenting to six urban community maternity clinics. The current report describes the patterns of smoking in this population of ethnoculturally diverse low-income urban pregnant women and examines differences across subgroups. The majority of the total sample in the current study reported that they had never smoked. Of the total, 30% reported having "ever" smoked and 16% were current smokers. Of the group of "ever" smokers, 18% quit greater than 12 months before pregnancy, 5% quit 0-12 months before pregnancy and 23% quit during this pregnancy. On the average, women who quit during pregnancy did so about 5 weeks after diagnosis. Of those women who continued to smoke during pregnancy, the average number of cigarettes smoked per day was 10 +/- 8. Differences were found in smoking patterns across the ethnocultural subgroups. Recruitment represents the first and one of the most important phases in intervening with pregnant women. Inclusion of both current smokers and recent self-quitters takes the fullest advantage of the window of opportunity to help women quit smoking and remain cigarette free for good.     

The nicotine inhaler in smoking cessation

BACKGROUND: Nicotine replacement therapy has been shown to improve success rates in smoking cessation treatment. However, the available products cause adverse effects, which prevent some smokers from using them. A new method of delivering nicotine via inhaler supplies nicotine orally through inhalation from a plastic tube. This mode of delivering nicotine resembles smoking, as it includes handling and active inhalation. OBJECTIVES: To assess the efficacy and safety of the nicotine inhaler as an aid in smoking cessation. METHODS: A 1-year, randomized, double-blind, placebo-controlled study was conducted in a smoking cessation clinic. Two hundred forty-seven smokers who smoked at least 10 cigarettes per day and who had previously made a serious attempt to stop smoking using nicotine chewing gum were recruited through advertisements. Randomization to treatment or control conditions were made at the first group session, with 123 participants receiving nicotine inhalers and 124 receiving placebo inhalers. The inhalers were distributed at the second session and participants were allowed to use the inhalers for 6 months. MAIN OUTCOME MEASURE: Biochemically verified continuous abstinence from smoking after 2 and 6 weeks and at 3, 6, and 12 months. RESULTS: Significantly more participants who had used the nicotine inhalers were continuously abstinent compared with those who had used the placebo inhalers. The respective success rates after 12 months were 28% and 18% (P = .046). At 6 months, 20 participants (16%) in the nicotine group were still using the inhaler, compared with 4 (3%) in the control group (P < .001). CONCLUSION: The nicotine inhaler was an effective smoking cessation aid that produced a few mild and transient adverse effects.     

Identifying individuals with high fat levels and low P:S ratios, in their diets, for intensive dietary intervention

OBJECTIVE: Interindividual variability in plasma concentrations of nicotine and its proximate metabolite, cotinine, is considerable during smoking and transdermal nicotine treatment, even among individuals taking in nominally similar doses of nicotine. This report explores the determinants of this variability and the utility of baseline (smoking) plasma concentrations to predict concentrations during transdermal nicotine treatment. METHODS: Data were analysed from a smoking cessation study (n = 466), and from a pharmacokinetic study (n = 12). Multiple regression models examined the relationships of plasma concentrations to individual characteristics such as smoking pattern, absorbed dose of nicotine, and pharmacokinetic parameters. RESULTS: Plasma concentrations of nicotine and cotinine were highly variable in both studies. Indirect estimates of plasma clearance (baseline plasma concentration divided by cigarettes per day) together with other factors could account for 18 to 33% of the variability during transdermal nicotine treatment in the smoking cessation study. In contrast, 75 to 99% was accounted for by direct measurements of plasma clearances and systemic dose of nicotine in the pharmacokinetic study. CONCLUSION: Plasma concentrations of nicotine and cotinine during transdermal nicotine treatment are poorly predicted by clinical history or baseline plasma concentrations. This is a result of inadequate characterisation of highly variable individual pharmacokinetic parameters and absorbed dose of nicotine. Considering the interindividual variability of plasma nicotine and cotinine concentrations together with the lack of clinical end-points for transdermal nicotine dosing, it seems logical to investigate the utility of a therapeutic drug monitoring approach for transdermal nicotine treatment-particularly for high dose regimens (> 22 mg per 24 hours).     

Notes on the intermediary form of incontinentia pigmenti

In a survey of a representative sample of 900 persons in Switzerland (excluding the Italian speaking parts comprising some 4-5 percent of the population), the smoking habits of the adult population were studied. Smokers were defined as persons smoking at least one cigarette or an equivalent weight of pipe tobacco or cigars per day. 51.8% of men and 29.0% of women over age 15 are smokers. Among male smokers of cigarettes only (42% of all men), over three quarters (77.6%) smoke ten cigarettes or more per day, i.e., a quantity found harmful to health; over one half (55.8%) smoke twenty or more cigarettes per day. Half of all female smokers smoke ten or more cigarettes, more than one in every four female smokers (28.8%) smoke twenty or more cigarettes per day. It is calculated that almost two thirds of all cigarettes sold in Switzerland are smoked by smokers of twenty or more cigarettes per day, and that almost three quarters are smoked by smokers of ten or more cigarettes. Among men, smoking habits are independent of social status, whereas among women, those with higher family incomes show more frequent smoking, but also more widespread cessation of smoking than with lower incomes. Thirty percent of adults having been smokers have given up the habit, so that among men and women above age 15, theree are now some 20% and 14% respectively, of ex-smokers. This corresponds to at least 700,000 former smokers in all of Switzerland. The trend to give up starts already in the group aged 15-24 (over 20% of men and women having ever smoked have given up) and becomes more marked with increasing age. A large part of male and female smokers would like to free themselves of the habit. 30% of male and 34% of female smokers indicate that they had tried seriously to stop smoking during the twelve months preceding the interview. Trying to give up was not significantly associated with intensity of smoking or social status. According to this survey, a majority of the population (57.6%) is in favor of reserving certain parts of restaurants to non-smokers, following the example of non-smokers-compartments in railway trains. In a situation where a non-smoker asks a co-worker in a closed room not to smoke, 78.3% take sides with the non-smoker, either by conceding to him a right to smoke-free air, or by demanding from the smoker to show consideration for the non-smoker. Only 10.9% demand from the non-smoker understanding for the smoker, or concede to the smoker a right to smoke at work. Women show more understanding for cause of the non-smoker than men. This difference is more marked among smokers and former smokers than among non-smokers. Inasmuch as the results of this study are comparable to those of earlier surveys conducted in Switzerland, ther is good agreement. The only exception is a significant increase of the proportion of former smokers in the past years.     

Stress, depressive symptoms, and smoking cessation among pregnant women.

Perceived stress and depressive symptoms were examined as correlates and predictors of smoking cessation during pregnancy in a sample of 819 pregnant smokers (454 baseline smokers and 365 baseline quitters). Women who quit early in pregnancy had lower levels of stress and depressive symptoms than baseline smokers. Adjusting for level of addiction and other demographic factors related to stress and depressive symptoms eliminated the significant association between depressive symptoms and smoking cessation. Lower levels of stress and depressive symptoms were not predictive of cessation in later pregnancy. Prenatal healthcare providers should continue to assess level of addiction and provide targeted intensive cessation interventions. Interventions that reduce stress and depression may also be of benefit to women who are continuing smokers in early pregnancy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An open trial of transdermal nicotine replacement therapy for smoking cessation among alcohol- and drug-dependent inpatients

An open trial of transdermal nicotine replacement for smoking cessation was conducted. Over a 7-month period, all patients admitted to the inpatient alcohol and drug treatment unit of the Seattle Veterans Affairs Medical Center, (n = 207) were offered the opportunity to participate in an open trial of transdermal nicotine replacement for smoking cessation. Forty-nine (23.7%) elected to attempt cessation with transdermal nicotine during their inpatient treatment episodes. These subjects received no psychosocial treatments directed specifically at smoking cessation. They smoked a mean of 28.5 (SD = 16.4) cigarettes per day and obtained a mean score of 8.3 (SD = 1.9) on the Fagerstrom Test for Nicotine Dependence. Subjects remained on transdermal nicotine an average of 18.8 (SD = 8.2) days with desire to resume smoking the major reason for discontinuation. Seven subjects (14.3%) self-reported tobacco abstinence at 21 days, and 5 (10.2%) self-reported abstinence as outpatients at 6 weeks. These results show that a substantial proportion of alcohol- and drug-dependent patients entering inpatient treatment are willing to attempt alcohol and illicit drug cessation and tobacco cessation simultaneously and that transdermal nicotine holds promise as a treatment modality in this population.
