Success of a smoking cessation program among smoking relatives of patients with serious smoking-related pulmonary disorders.

The aim of the study was to investigate the success of a smoking cessation program among the smoking relatives of patients with serious smoking-related disorders and to determine whether having a relative with such a disorder influences the rate of success of the program. The relatives of patients with chronic obstructive pulmonary disease (COPD) and lung cancer who wanted to quit smoking were included in the smoking cessation program (group I, n = 34). During the same period, the same number of subjects with relatives free of any smoking-related diseases were included as a control group (group II, n = 34). Intensive behavioral therapy and motivational support was given to all subjects. Nicotine replacement therapy was administered to 10 subjects (29.4%) in group I and 14 subjects (41.2%) in group II. The subjects were evaluated in the 1st, 2nd, 4th, 8th and 12th week and subsequently every 3 months for a year in the outpatient clinic and proactive telephone interviews were performed periodically. In group I, 23.5% of subjects had a relative with COPD, 61.8% had relatives with lung cancer, and 14.7% had relatives with both COPD and lung cancer. The rate of quitting smoking was 79.4 and 73.5% on the 15th day and 41.2 and 38.2% at the end of the 1st year in groups I and II, respectively (p > 0.05). We observed that having a relative with serious smoking-related disorders did not motivate smokers to quit smoking.

Reductions in tobacco smoke pollution and increases in support for smoke-free public places following the implementation of comprehensive smoke-free workplace legislation in the Republic of Ireland: findings from the ITC Ireland/UK Survey.

OBJECTIVE: To evaluate the psychosocial and behavioural impact of the first ever national level comprehensive workplace smoke-free law, implemented in Ireland in March 2004. DESIGN: Quasi-experimental prospective cohort survey: parallel cohort telephone surveys of national representative samples of adult smokers in Ireland (n = 769) and the UK (n = 416), surveyed before the law (December 2003 to January 2004) and 8-9 months after the law (December 2004 to January 2005). MAIN OUTCOME MEASURES: Respondents' reports of smoking in key public venues, support for total bans in those key venues, and behavioural changes due to the law. RESULTS: The Irish law led to dramatic declines in reported smoking in all venues, including workplaces (62% to 14%), restaurants (85% to 3%), and bars/pubs (98% to 5%). Support for total bans among Irish smokers increased in all venues, including workplaces (43% to 67%), restaurants (45% to 77%), and bars/pubs (13% to 46%). Overall, 83% of Irish smokers reported that the smoke-free law was a "good" or "very good" thing. The proportion of Irish homes with smoking bans also increased. Approximately 46% of Irish smokers reported that the law had made them more likely to quit. Among Irish smokers who had quit at post-legislation, 80% reported that the law had helped them quit and 88% reported that the law helped them stay quit. CONCLUSION: The Ireland smoke-free law stands as a positive example of how a population-level policy intervention can achieve its public health goals while achieving a high level of acceptance among smokers. These findings support initiatives in many countries toward implementing smoke-free legislation, particularly those who have ratified the Framework Convention on Tobacco Control, which calls for legislation to reduce tobacco smoke pollution.

Smoking habits, exposure to passive smoking and attitudes to a non-smoking policy among hospital staff.

A survey was carried out into the smoking habits and exposure to passive smoking among health staff in the hospitals of Faenza, Forli and Rimini (Emilia-Romagna, Northern Italy), 2453 subjects answered anonymously a 41 question questionnaire. 53% of the subjects were professionals nurses, 16% doctors, 15% maintenance staff, 10% ancillary staff, 1% non-medical graduates, 2% were administrators and 3% were assigned to the category ¿other'. Of the subjects answering the questionnaire 39% were smokers, 19% ex-smokers and 42% non smokers. The highest number of smokers was found among women (41%) compared to men (37%) and among ancillary staff (48%) compared to nurses (41%) and doctors (31%). The males were mostly heavy smokers (> or = 20 cigarettes/d) and smoked strong cigarettes (> or = 12 mg/cig condensate content). The females were mostly light smokers (< 10 cigarettes/d) and smoked light cigarettes (1-6 mg/cig condensate content). A high percentage of subjects (87%) smoked at work especially in areas reserved for staff. 43% and 26% of shift workers and non-shift workers tended not to modify their habit when on morning or afternoon shifts. During night shifts the majority of them increased their tobacco consumption. Around 87% of hospital employees stated they were exposed to passive smoking inside the hospital especially in cooking areas, at information desks and corridors. Nurses, ancillaries and maintenance staff were those most exposed and for a greater number of hours per day compared to doctors. Almost all subjects were aware of the harm caused by passive smoking. 56% of smokers, 65% of ex-smokers and 72% of non smokers said they were willing to participate in future campaigns to limit smoking in their hospitals.

[Smoking by an Israeli general hospital staff, and attitude to smoking in hospitals. Are we in Israel ready to institute "smoke-free hospitals"?].

Smoking within hospitals is common in general hospitals in Israel. It has a strong negative educational impact, has a negative image and curing its ill effects help keep our hospitals busy. An anonymous questionnaire was answered by 128 members of our hospital staff (28%). Their distribution, according to occupation and sex was representative of the rest of our hospital staff. 19% of our workers are smokers, a much lower proportion than in our general adult population. The proportion was highest among maintenance (40%) and sanitary-help staff (36%). 23% of nurses and 15% of physicians were smokers. This situation is better than that among Italian or Japanese medical staff, but much worse than among North American medical staff. 75% of our workers who smoke declared that they smoke outside the room in which they work. 66% and 72% of the staff believe that hospital workers and visitors, respectively, should smoke outside hospital buildings. Only 19% of all workers do not believe that a "smoke-free hospital" is attainable. 34% believe that a "smoke-free hospital" is achievable, and 47% said that it is perhaps achievable. 86% of all the workers, and 41% of the smokers, expect the hospital director to implement an effective policy of enforcing the law limiting smoking within hospitals (and other public buildings) in Israel. 60% are willing to contribute actively to this effort. We believe these results strongly suggest that the time is ripe for implementation of the "smoke-free hospital" in Israel. This requires a strong and effective central policy, like that in the USA. We suggest measures that the Israel Ministry of Health take measures to successfully implement this policy.

The natural history of cigarette smoking: predicting young-adult smoking outcomes from adolescent smoking patterns.

Assessed the magnitude of risk that adolescent cigarette smoking carries for adult smoking. Using a longitudinal, prospective design, results indicate that even infrequent experimentation in adolescence significantly raises the risk for adult smoking and that regular (at least monthly) adolescent smoking raises the risk for adult smoking by a factor of 16 compared to nonsmoking adolescents. Relative risk was also increased by an early onset of smoking and by a stable, uninterrupted course from experimentation to regular smoking. Relative risk did not significantly vary by age or sex. The continuity of smoking behavior between adolescence and adulthood supports the importance of primary prevention programs directed at adolescent populations.

Smoking, exposure to secondhand smoke, and smoking restrictions in Tijuana, Mexico.

OBJECTIVE: To estimate the prevalence of tobacco use, exposure to secondhand smoke, and smoking restrictions in the home and workplace among residents of Tijuana, one of Mexico's largest cities. METHODS: This cross-sectional household survey was conducted in Tijuana, Baja California, Mexico, during 2003 and 2004. A population-based sample of 400 Tijuana adult residents responded to a tobacco survey, and 397 of the surveys were analyzed. RESULTS: About 22.9% (95% confidence interval (CI): 18.7%-27.1%) of Tijuana adults reported current smoking, and 53.9% (95% CI: 48.8%-58.9%) reported chronic exposure to secondhand smoke. Approximately 44.4% (95% CI: 37.9%-50.9%) of Tijuana adults had a nonsmoking policy in their workplace, while 65.8% (95% CI: 61.0%-70.6%) of Tijuana households were smoke-free. CONCLUSIONS: The results underline the need for increased tobacco control efforts, particularly stricter enforcement of existing passive smoking regulations, in order to expand protection from secondhand smoke from private settings to public ones and to curb the tobacco epidemic in Tijuana and elsewhere in Mexico.

The nurse as exemplar: smoking status as a predictor of attitude toward smoking and smoking cessation.

The smoking behavior of oncology nurses is of particular concern, not only because of the personal risk, but also because of the negative influence the behavior may have on the public. A survey of 316 female oncology nurses in Texas was conducted to assess smoking prevalence in this sample and the manner in which smoking status impacts the attitudes of these nurses toward their roles as exemplars and advocates for nonsmoking. The prevalence of smoking in this sample of oncology nurses was 7%, with an additional 26.2% being ex-smokers, supporting a downward trend in smoking among oncology nurses. Differences among oncology nurses who were smokers, ex-smokers, or nonsmokers concerning their attitudes toward smoking were investigated. Nonsmokers and ex-smokers showed a more positive attitude toward their roles as exemplars and in counseling the public about the health hazards of smoking.

Are patients truthful about their smoking habits? A validation of self-report about smoking cessation with biochemical markers of smoking activity amongst patients with ischaemic heart disease.

AIMS: To validate self-report about smoking cessation with biochemical markers of smoking activity amongst patients with ischaemic heart disease. PATIENTS AND METHODS: Outpatients at the Division of Cardiology, 75 years of age or younger, who had been Hospitalized at Sahlgrenska University Hospital in Göteborg due to an ischaemic event and who consecutively participated in a nurse-monitored routine care programme for secondary prevention, from 6 February 1997 to 5 February 1998. Data concerning smoking habits were collected through interviews. Two chemical markers, cotinine in plasma and carbon monoxide (CO) in expired air, validated self-reports concerning smoking cessation. RESULTS: 260 former smokers were validated. In the vast majority of the study population, the anamnestic information concurred with the chemical marker. However, 17 patients had chemical markers that contradicted their self-report with raised CO (n = 6) and/or raised cotinine levels (n = 13) without alternative nicotine delivery. CONCLUSION: Most patients with coronary artery disease relating information concerning cessation of smoking are truthful. A few patients, however, seem to conceal their smoking. Testing by chemical markers may be questionable for ordinary care but should, however, be included in studies concerning the association between smoking and health.

No association between functional catechol O-methyl transferase 1947A>G polymorphism and smoking initiation, persistent smoking or smoking cessation.

Nicotine stimulates dopamine release and activates dopaminergic reward neurones in central pathways giving rise to dependence. Catechol O-methyl transferase (COMT) inactivates extraneuronally released dopamine and is present in dopaminergic brain regions. A functional polymorphism (COMT 1947A>G) resulting in increased enzyme activity has been associated with alcoholism and polysubstance abuse. We examined the relationship between the COMT 1947A>G polymorphism and smoking initiation, smoking persistence and smoking cessation. We genotyped 266 current smokers, 270 ex-smokers and 265 lifetime non-smokers (never smokers), matched for age and gender, for the COMT 1947A>G polymorphism. Smoking status was ascertained by self-report. There was no difference in genotype frequencies between never smokers and ever smokers (current + ex-smokers); between non-smokers (never + ex-smokers) and current smokers; or between current smokers and ex-smokers. These data suggest that the COMT 1947A>G polymorphism is not associated with smoking initiation, smoking persistence or smoking cessation.

Smoking and vigilance. The effects of tobacco smoking on CFF as related to personality and smoking habits.

The effects of tobacco smoking on vigilance (Critical Flicker Fusion, CFF) measured by a computerized forced-choice interactive technique, was studied in a group of 28 male moderate smokers. Subjects participated in a Smoking (S) and a Non-Smoking (NS) condition each of 1 h duration. CFF performance was measured during fifteen 2-min trials in each condition. In the S condition subjects smoked three puffs during each of five pauses between five successive trials. Vigilance was significantly improved by smoking. An initial sharp increase in CFF performance was noticed with a maximum 8 min after the first puff. Performance was significantly higher in the S condition compared to the NS condition up to 20 min after the last puff. Two extreme groups, based on differences in CFF performance between the S and NS condition were compared by questionnaires on personality and smoking habits. The most improved group had significantly higher scores in an extraversion scale. Ratings of the effect of smoking on level of alertness indicated that the objective effect of increased vigilance had no counterpart on the subjective level.

Socioeconomic predictors of smoking and smoking frequency in urban China: evidence of smoking as a social function.

A number of previous studies have documented the worsening smoking problems in China. This paper identifies several key socioeconomic variables associated with smoking among urban working adults and calls researchers' attention to the important function of cigarette smoking as a social connection builder in China. This study argues that a smoking prevention and education program should place more emphasis on making smoking socially unnecessary and/or unacceptable because of the continuing increase in the number of smokers and the low desire to quit among smokers. The findings also suggest that while socioeconomic characteristics are excellent in predicting whether a person smokes or not, they are dismal in predicting smoking frequency among working adults.

Twin concordance for a binary trait. II. Nested analysis of ever-smoking and ex-smoking traits and unnested analysis of a "committed-smoking" trait.

Twin concordance rates for a binary trait can provide information about causes of trait variation. However, if trait prevalence varies with age (or birth cohort) or between the sexes, trait concordance rates will be artificially inflated because of the matching within pairs of twins. Our previous paper showed how to minimize the effects of such confounding by using logistic regression to model trait prevalence as a function of age and sex and that the binary correlation coefficient was useful as a measure of concordance that can be adjusted for trait prevalence. This method is extended here to allow for nested analyses and is applied to the smoking habits of a sample of 3,807 pairs of adult twins. For monozygotic (MZ) twins, the correlation coefficients for the binary trait of "ever-smoking" (males: .50 +/- .04; females: .60 +/- .02) were significantly greater than for dizygotic (DZ) twins (males: .37 +/- .05; females: .31 +/- .04; unlike-sex pairs: .21 +/- .03). For "giving-up smoking," given that both twins were previously smokers, the correlations for MZ twins (males: .37 +/- .07; females: .29 +/- .05) were also greater than for DZ twins (males: .11 +/- .09; females: .26 +/- .08; unlike-sex pairs: .13 +/- .06), although the difference was not statistically significant for females. Current smokers who had been smoking for at least 10 years were arbitrarily defined as "committed-smokers." The binary trait of "committed-smoking" was more strongly correlated in MZ twins (males: .41 +/- .06; females: .41 +/- .04) than in DZ twins (males: .22 +/- .08; females: .18 +/- .05; unlike-sex pairs: .16 +/- .05). These observations suggest that as well as depending on socially determined environmental factors, smoking behavior is influenced by genetic factors and/or by environmental factors unique to the MZ twin environment, which are of particular importance as determinants of "committed-smoking." There is a need for further research to investigate the personal characteristics of "committed-smokers" and to seek intervention strategies that are more suited to the needs of individual smokers.

Exposure to smoking-relevant cues: effects on desire to smoke and topographical components of smoking behavior.

The effects of exposure to two classes of smoking-relevant cues (environmental; negative affect) on desire to smoke and smoking topography were evaluated. Sixty chronic smokers were randomly assigned to one of six groups in a two-way ANOVA design in which the salience of environmental cues and presence of negative affective cues were manipulated. This was followed by a 20-minute interval during which ad libitum smoking was videotaped in an unobtrusive manner. Results indicated that the experimental manipulations differentially influenced ratings of desire and topographical components of smoking behavior. Implications are raised regarding the role of cue reactivity in the maintenance of smoking behavior.

Perceived health: a test of incremental validity in relation to smoking outcome expectancies, motivation to smoke and desire to quit smoking.

This study examined the role of perceived health in predicting theoretically-relevant aspects of smoking behavior among 161 young adult regular smokers (67 females; mean age = 21.9 years (SD = 7.2), cigarettes per day (M) = 12.2 (SD = 5.7)) recruited from the general community. Consistent with prediction, results indicated that relative to anxiety sensitivity, gender, number of cigarettes smoked per day and nicotine dependence, perceived physical health uniquely and significantly predicted expectancies for negative affect reduction and expectancies that smoking would lead to negative personal consequences. Additionally, perceived health incrementally predicted motivation to smoke to reduce negative affect. In contrast to expectation, perceived health was unrelated to motivation to quit smoking. Results are discussed in relation to the role of perceived health as a cognitive vulnerability factor for specific types of smoking patterns.

Where there's smoke...carbon monoxide exposures in smoking and smoke-free workplaces.

Comparisons of expired air carbon monoxide levels in non-smoking staff in six licensed clubs (a smoking workplace) were made with those of non-smoking staff of a large public hospital (a smoke-free workplace). There was a significant difference between clubs and hospital in levels of CO at end of work. The average concentration of club workers was 8.7 ppm (Hospital, 5.3 ppm). Approximately one third of these non-smokers in licensed clubs exceeded 10 ppm putting them in the 'light smoker' category according to the manufacturer of the monitoring equipment. Club workers increased their CO level during work time by four times the increase of Hospital staff. This study suggests that there are significant gains to be made in reduction of intake of harmful passive-smoking products by removing tobacco smoke from workplaces.

Environmental tobacco smoke concentrations in no-smoking and smoking sections of restaurants.

To characterize the effectiveness of a local ordinance that restricts smoking in restaurants to one third of the seating area, this study made simultaneous measurements of two markers of environmental tobacco smoke, respirable suspended particles and nicotine, in the smoking and no-smoking sections of seven restaurants. The mean concentrations of respirable suspended particles and nicotine were 40% and 65% lower, respectively, in the no-smoking than in the smoking sections, indicating substantial but not complete protection against exposure.

Texas college students' opinions of no-smoking policies, secondhand smoke, and smoking in public places.

Abstract. The authors examined college student opinions of no-smoking policies, secondhand smoke, and smoking in public places. A convenience sample of 1,188 (66.4% female; 26.9% White, 64.1% Black, and 9.0% Hispanic) students attending 5 Texas colleges volunteered to complete a 60-item anonymous survey on tobacco attitudes and behaviors. Results of our study showed that women, Black students, and nonsmoking students reported the most favorable attitudes toward no smoking. Male students, white students, and students who smoked in the past 30 days (current smokers) reported the least favorable attitudes. The lowest level of agreement by all subgroups was provided for prohibiting smoking everywhere on campus (inside and outside of buildings). Implications for tobacco control on college campuses are discussed.

The impact of California's smoking ordinances on worksite smoking policy and exposure to environmental tobacco smoke.

A subsample of 5776 respondents to the California Tobacco Survey who do not smoke and work indoors outside of their home was analyzed regarding worksite smoking policy and worksite exposure to environmental tobacco smoke. To obtain study results, survey responses were linked to tobacco ordinance data. Nonsmokers who worked in localities with moderate or strong laws were more likely to report worksite smoking policies than nonsmokers in localities without laws. Even in localities with strong laws, 23.5% of respondents reported no worksite policy, and 26.4% reported recent exposure to environmental tobacco smoke at the worksite. Comprehensive laws with minimal exemptions may be necessary to ensure adequate compliance and protection from environmental tobacco smoke.
