Eight smokers participated in a smoking-cessation program involving controlled situational reduction and behavioral substitution. Six completed the treatment, and over-all reduction was significant. Reduction was maintained at 12-month follow-up. Ratings of positive images of smoking also changed posttreatment.
Twenty-seven smokers were classified pretreatment according to whether they reported high craving to smoke when they were actively engaged (n = 14) in a task or not (n = 13). Both groups reported reduced smoking and craving during a situation-based reduction program. But the former group showed a more consistent increase in self-efficacy, positive change in mood, and reported less relapse at six-month follow-up. We conclude that in our sample, situation-based reduction suited those with a preference to smoke during more goal-directed activities.
In 1987, in Italy, 27,106 men and 4,159 women died from lung cancer or larynx cancer. Taking into consideration the smoking habits of the Italian population and the relative risks for pulmonary cancer, of smokers and ex-smokers versus nerve smokers, we estimate that 87% of deaths can be attributed to smoking. We know from previous studies that quitting smoking results in the reduction of the risk elapsed since quitting and that this reduction depends on the time and on the quantity of tobacco previously smoked before the cessation. We estimated the reduction in the number of deaths due to respiratory cancer if part of the population were to quit smoking. In males aged 35-74 years after 12 years, there would be 3,604 fewer deaths if 10% quit smoking and 11,915 fewer deaths if 100% quit smoking.
The objective for this formative evaluation was to establish baseline data for informing a community coalition's strategic planning in environmental tobacco smoke (ETS) risk reduction. The coalition had chosen 3 targeted settings for ETS risk reduction: restaurants, childcare facilities, and government buildings. The evaluation methodology involved telephone interviews (restaurants, n = 805; governmental buildings, n = 258) and mailed surveys (childcare facilities, n = 1,142). Data on county residents and businesses were used for comparison purposes and were analyzed from the Nebraska Social Climate Survey (2001; n = 558). Evaluation baseline findings showed that licensed childcare facilities were more ETS knowledgeable, less ETS tolerant, and more smoke-free than restaurants. Residents were more bothered by ETS than what restaurant proprietors perceived. The majority of governmental buildings were not smoke-free. Conclusions were that community health nurse evaluators can provide coalitions with formative evaluative data to inform strategic planning and increase the likelihood of effective program interventions for community impact on ETS.
OBJECTIVE: Radon and cigarette smoking have synergistic effects on lung cancer, even when radon concentrations are relatively low. Working through an electric utility company, we sought to reach smoking households with low radon concentrations and motivate smoking cessation or prohibiting smoking in the home. DESIGN: Eligible homes (n = 714) were randomised to receive: (1) the Environmental Protection Agency's (EPA's) "A citizen's guide to radon"; (2) a specially developed pamphlet; or (3) that pamphlet plus brief telephone counselling. PROCEDURE: Utility company "bill stuffers" offered free radon test kits to smoking households. All households received radon test results with an explanatory cover letter. Both the specially developed pamphlet and the telephone counselling emphasised that smoking cessation or prohibiting smoking in the home were the optimal risk reduction strategies. Households were followed up at 3 and 12 months after receiving materials. RESULTS: The specially developed pamphlet and the EPA guide yielded similar outcomes. There was a non-significant trend for telephone counselling to produce greater sustained quitting than the specially developed pamphlet, and phone counselling led to significantly more new household smoking bans. CONCLUSIONS: Working through a public utility company is an efficient way to reach smoking households, and brief telephone counselling is a promising method for promoting household smoking bans and cessation in homes alerted to the risk posed by the combination of radon and smoking.
We examined the ability of smokers who failed to quit smoking in the Lung Health Study to reduce the number of cigarettes per day and maintain this reduction and whether reduction predicted increased or decreased future cessation. In the Lung Health Study, among smokers with early lung disease who wished to stop smoking, 3923 were randomized to a special intervention of counseling and nicotine gum for smoking cessation and to bronchodilator therapy or placebo. Among the 1722 who were still smoking at the first year follow-up, 27% smoked the same, 43% smoked 1%-49% fewer, and 30% smoked at least 50% fewer cigarettes per day. Reduction in cigarettes per day was accompanied by reduction in expired-air carbon monoxide. About half of the less-than-50% reducers and one-fifth of the at-least-50% reducers maintained or exceeded this reduction over the next 4 years. Reduction was associated with nicotine gum use. Greater reduction at year 1 predicted more quit attempts in year 2 but not more point prevalence abstinence at year 2 nor more quits or abstinence between years 2 and 5. We conclude that reduction can be maintained but such reduction neither predicts an increased nor decreased probability of future cessation.
This paper deals with the hazard of smoke production to patients undergoing endoscopic surgery. A study investigating methaemoglobin levels in a patient group operated on using smoke generating devices as compared to a control group yielded a significantly positive correlation between smoke production and methaemoglobin concentration. The mechanisms controlling methaemoglobin levels in the body and the specific toxic effect of elevated levels are dealt with. It is concluded that smoke production in endoscopic surgery is a factor of concern and should be minimized.
Participants were women (N = 16) living with their children in a residential substance abuse treatment facility. In this within-subjects repeated measures study, a 1-week baseline was followed by a 4-week intervention and a 2-week follow-up (same as the baseline). The intervention consisted of exposure to an educational video and a smoking cessation workbook, brief individual support meetings, and an escalating schedule of voucher-based reinforcement of abstinence. Throughout the study, three daily breath samples (8 a.m., noon, and 4 p.m.) were collected Monday through Friday to determine carbon monoxide (CO) concentration. In addition, urine cotinine (COT) was assessed on Monday mornings to monitor weekend tobacco use. Participants received vouchers of escalating value for CO-negative breath and COT-negative urine samples. Positive samples reset the voucher value. Significantly more negative tests were submitted during the intervention than during baseline and follow-up. The intensive behavioral intervention evaluated in this study produced a substantial reduction in cigarette smoking, and 25% of participants remained abstinent 2 weeks after the intervention was suspended. Nevertheless, the percentage of CO-negative samples submitted during the follow-up returned to baseline levels. While retaining many real-world characteristics, residential treatment facilities provide important opportunities for smoking cessation treatment and research.
This study compared two behavioral treatments on their efficacy and acceptability in reducing smoking, using a crossover design with interposed return to baseline, 2 weeks/condition. 20 US cigarette smokers reporting an interest in reducing, but not quitting, their smoking either increased the inter-cigarette interval or selected easy cigarettes to eliminate, with a goal of 50% reduction. Nicotine gum accompanied both treatments. Measurements taken were self-reported cigarettes per day, carbon monoxide, cotinine, and thiocyanate; self-rated acceptability of the treatments; adverse events. Both treatments decreased self-reported cigarettes per day (-45% and -38%) and carbon monoxide (-20% and -19%), but not cotinine or thiocyanate. Increasing the inter-cigarette interval produced slightly more reduction in cigarettes per day than cigarette selection, but no other differences were found. Both treatments were acceptable and safe. Although our sample size was small and the duration of reduction documented short, both treatments appear to be acceptable and efficacious behavioral treatments for reduction.

AIMS: To assess to what extent snus has been used as an aid to stop smoking among Swedish smokers. DESIGN: A random telephone retrospective survey of Swedish smokers and ex-smokers. SETTING: Survey conducted in November-December 2000. PARTICIPANTS: A national sample of 1000 former and 985 current daily smokers aged 25-55 years. MEASUREMENTS: Smoking status, date and method of quitting by self-report. FINDINGS: Thirty-three per cent of former smokers and 27% of current smokers had ever used snus. The difference was larger among men (55% versus 45%, P = 0.003). Current smokers who made use of snus smoked on average fewer cigarettes per day than non-users of snus. The mean duration of abstinence among former smokers was not influenced by snus use. Conditionally on age, education and use of nicotine replacement therapy there was an increased probability of being a former rather than a current smoker with ever use (OR 1.72, 95% CI = 1.30-2.28) or current use (OR 1.81, 95% CI = 1.31-2.53) of snus. Having used snus at the latest quit attempt increased the probability of being abstinent by about 50% (OR 1.54, 95% CI = 1.09-2.20). CONCLUSIONS: Our study suggests that by using snus, Swedish male smokers may increase their overall chances of abstinence. However, 71% of the men in this sample who quit smoking did so without using snus and the duration of abstinence was not affected by snus use. This suggests that snus is not a necessary component of smoking cessation at the population level. Snus use was very rare among women.
OBJECTIVES: To determine the smoking cessation/reduction services offered to pregnant women by federally funded Healthy Start projects designed to reduce infant mortality. DESIGN: Information was obtained by questionnaires sent to all Healthy Start projects in 1999. Responses were received from 76 sites. SETTING: The federal government selected the Healthy Start sites on the basis of infant mortality rates that were much in excess of the national average. PATIENTS: The projects served largely minority clients. Most of the women were poor and eligible for Medicaid. MAIN OUTCOME MEASURES: The services that projects offered to pregnant smokers, the priority given the smoking related activities, and whether more should be done. RESULTS: Only 23% of the sites thought that they were doing enough to help pregnant smokers stop or reduce smoking. The sites felt the national office should develop a manual of best practices, provide client materials, and organise workshops. While three quarters of the sites expected home visitors to counsel pregnant smokers, less than half provided training in this area during orientation, but most visitors received on-the-job training. Only 64% of sites gave smoking cessation/reduction activities high priority in comparison to other objectives of home visiting. CONCLUSIONS: Although Healthy Start sites were aware of the importance of smoking cessation/reduction activities for their clients, they offered a limited range of services. These projects, and others with similar objectives serving similar populations, need a better understanding of the time and money such interventions require and greater belief in their effectiveness, along with more funds, staff training and materials, and office systems that promote counselling.
Monks in a rural community in northern Thailand were observed to conduct anti-smoking activities. To evaluate the effects of the monks' efforts on change of people's smoking behaviour and attitudes, we conducted a survey of adults > or = 15 years of age in this village (intervention village sample) and a randomly selected village (control village sample) in the same subdistrict. Between March and April 1991, we interviewed 372 individuals in the intervention village and 664 in the control village. The two villages were of similar socioeconomic status. The proportion of ever smokers who had tried to quit was greater in the intervention sample (79.6%) than in the control sample (72.0%) (P = 0.048). The proportion of former smokers who had stopped smoking for > or = 1 year was significantly greater in the intervention sample (25.5% of ever smokers) than in the control sample (16.6%) (P = 0.011). Of current smokers in the intervention village, 45.8% reported smoking less tobacco during the year preceding the survey than in the previous 1-year period compared with 35.2% in the control village (P = 0.034). Many former smokers (80.3%) in the intervention village cited the suggestion of a monk as one important reason for quitting compared with 25.6% in the control village (P = 0.000). The proportion of individuals who were well aware of the harmful effects of smoking on health was greater in the intervention village than in the control village. Religious leaders may be helpful in a community-based smoking prevention programme.

STUDY OBJECTIVES: To determine the effectiveness of a cotinine-feedback, behaviorally based education intervention in reducing environmental tobacco smoke (ETS) exposure and health-care utilization of children with asthma. DESIGN: Randomized controlled trial of educational intervention vs usual care. SETTING: The pediatric pulmonary service of a regional pediatric hospital. PARTICIPANTS: ETS-exposed, Medicaid/Medi-Cal-eligible, predominantly minority children who were 3 to 12 years old and who were seen for asthma in the hospital's emergency, inpatient, and outpatient services departments (n = 87). INTERVENTION: Three nurse-led sessions employing behavior-changing strategies and basic asthma education and that incorporated repeated feedback on the child's urinary cotinine level. MEASUREMENTS: The primary measurements were the urinary cotinine/creatinine ratio (CCR) and the number of acute asthma medical visits. The secondary measurements were number of hospitalizations, smoking restrictions in home, amount smoked, reported exposures of children, and asthma control. RESULTS: The intervention was associated with a significantly lower odds ratio (OR) for more than one acute asthma medical visit in the follow-up year, after adjusting for baseline visits (total visits, 87; OR, 0.32; p = 0.03), and a comparably sized but nonsignificant OR for one or more hospitalization (OR, 0.34; p = 0.14). The follow-up CCR measurement and the determination of whether smoking was prohibited inside the home strongly favored the intervention group (n = 51) (mean difference in CCR adjusted for baseline, -0.38; p = 0.26; n = 51) (60; OR [for proportion of subjects prohibiting smoking], 0.24; p = 0.11; n = 60). CONCLUSIONS: This intervention significantly reduced asthma health-care utilization in ETS-exposed, low-income, minority children. Effects sizes for urine cotinine and proportion prohibiting smoking were moderate to large but not statistically significant, possibly the result of reduced precision due to the loss of patients to active follow-up. Improving ETS reduction interventions and understanding their mechanism of action on asthma outcomes requires further controlled trials that measure ETS exposure and behavioral and disease outcomes concurrently.
1. Most people with mental illnesses have made at least one attempt to quit smoking on their own. 2. Psychiatric diagnosis and degree of nicotine dependence do not appear to be predictive of ability to quit. 3. People with mental illnesses are aware of nicotine replacement therapy (NRT), but do not combine it with a behavioral program, possibly contributing to the higher rates of recidivism in this population. 4. The lack of participation of mental health care providers in promoting smoking cessation is a complex issue.
