Serum thiocyanate, smoking habits and smoking cessation trial in patients with peripheral atherosclerosis

The smoking habits in patients with atherosclerosis in the lower limbs and the effect of advising them to stop smoking was studied by means of self-declaration of the number of cigarettes smoked per day and determination of serum thiocyanate. Ninety-six per cent of males and 70 per cent of the females were smokers or ex-smokers. The number of years of smoking was about 40 for the smokers of both sexes and the male ex-smokers and 23 for the female ex-smokers. The number of cigarettes smoked per day reported by the patients was less than that reported by the smokers in a reference population. The serum thiocyanate levels confirmed the smoking status of the non-smokers and showed that about one-sixth of the ex-smokers had smoked in the last month prior to the study, and that the smokers on the average were heavy smokers smoking much more than the self-reported number of cigarettes. The effect of advising the patients to quit smoking was very disappointing. A maximum of 15 per cent of the smokers stopped smoking while some of the ex-smokers resumed smoking.     

Smoking: knowledge, attitudes, habits and degree of dependence of young adults in Salvador

This study was aimed at evaluating the degree of smoking dependence and to characterize social demographic data, habits and attitudes of young smokers. Answered the questionnairel02 students from Salvador, State of Bahia, of which 11 were smokers. Their mean age and the age in which they first smoked were 18.2 and 13.4 years respectively. Most of them were male, in the first year of senior high school, of brown skin color and had close relatives who smoke. The majority of those young smokers had been advised about the risks of smoking at home and in school, but few had knowledge about the benefits of quitting. Almost half of them had been smoking for more than three years and had started to smoke out of curiosity. More than half of them smoked one cigarette per day, with low levels of nicotine, bought the cigarettes in shops, and wanted and tried to quit smoking, but never succeeded. The degree of dependence was low for most of them. This study offers hints for nurses to act against smoking with young adults.     

ExHALED Study: Prevalence of smoking and harm levels in an emergency department cohort

Objective: To determine the prevalence of smoking among ED patients compared with the general New Zealand (NZ) smoking prevalence. Secondary outcomes were to determine smokers' level of nicotine dependence, readiness to quit and engagement with primary health care. Methods: This was a prospective, cross‐sectional prevalence study of ED patients seen consecutively over 6 days in Wellington Hospital, Wellington South, NZ. Medically stable patients ≥18 years were asked about their smoking habits by a closed‐question survey. Results: Five hundred and twenty‐eight patients comprised the study group. The ED smoking prevalence was 33.1% and higher than the general NZ smoking prevalence of 20.7%. Of those who smoked, 26.3% were ‘moderately’ to ‘very highly’ dependent on nicotine (Fagerstrom Test for Nicotine Dependence, FTND score ≥5). Of those who smoked, 74.9% stated they wanted to quit, 42.9% wanted to quit within the next month and 60.6% wanted an ED quit smoking pack. There were 13.6% of ED patients not registered with a general practitioner; of this, 61.1% were current smokers and 70.5% wanted to quit smoking. Conclusions: The prevalence rates of smoking are higher among patients attending Wellington Hospital ED than the general NZ population and the majority would like to quit smoking. One in four ED smokers have a high FTND score and are considered nicotine‐dependent. Many patients who were not registered with a general practitioner smoked, and the majority wanted to quit. Finally, there is significant interest from ED patients in receiving quit smoking packs from the ED.     

No relation between angiotensin‐converting enzyme gene polymorphism and smoking dependence

Background: Smoking as a major risk factor for development of cancer and cardiovascular disease is thought to be partially genetically determined. The aim of this study was to investigate whether there is an association between insertion/deletion (I/D) polymorphism in angiotensin‐converting enzyme (ACE) and smoking status and the number of cigarettes smoked per week. Methods: Using polymerase chain reaction, I/D polymorphism was evaluated in the ACE gene in 1204 male and 1375 female representative Caucasians. Information about smoking status and number of cigarettes smoked per week was collected via a questionnaire. Results: Frequencies of the alleles and genotypes of ACE I/D polymorphism did not differ between smokers, past smokers and individuals who had never smoked. No association was found between ACE I/D polymorphism and the number of cigarettes smoked per week, either in males or in females. Conclusion: I/D polymorphism in the ACE gene does not play any role in genetic determination of predisposition to smoking.     

Smoking cessation after stroke: education and its effect on behavior.

Smoking is an independent risk factor for stroke. The purpose of this prospective study was to determine whether significant changes in smoking behavior occurred in a cohort of stroke patients who were educated about risk reduction during their initial recovery period. Participants or their proxies were then contacted at 3 months for a follow-up interview, during which their current location, smoking status, and functional outcome were recorded. Of 405 participants interviewed, 112 were current smokers at the time of stroke. Participants younger than 65 years and Blacks were more likely to be smokers. At 3 months, 48 (43%) of the baseline smokers had quit smoking compared with an estimated rate of 28% previously reported in the literature. The number of participants who smoked > 20 cigarettes per day was 31 at baseline versus 7 at 3 months. This change of behavior was independent of baseline characteristics and the level of poststroke disability. Risk-reduction education provides stroke survivors with the information needed to change their lifestyles. Further research is needed to determine whether this behavior continues beyond 3 months and to determine why some stroke survivors continue to smoke.     

Prevalence of tobacco smoking among urban population of Samara and causative factors

AIM: To examine prevalence and intensity of smoking among general population of Samara, physicians and students of Samara Medical University; to study dependence of this prevalence on different social factors. MATERIAL AND METHODS: A representative sample of adult population was selected by the lists of outpatients of Samara outpatient clinic. The study enrolled 2931 outpatients (1272 males, 1659 females aged 15 years and older)--3.95% of all Samara outpatients. The questionnaire survey covered 360 physicians aged 28-57 years (the response 96.5%), 652 senior medical students aged 21-24 years (the response 93.14%). The results were processed with the statistical computer program BIOSTAT. RESULTS: The percentage of smoking men among 15-19-year-olds was 42.94%, 20-29-year-olds--59.29% (p < 0.01), 30-39-year-olds--62.18%, 60-year-olds and older--35.64%. This proportion for smoking women was 15.04%, 27.11% (p < 0.01), 22.92%, 9.06% (p < 0.001), 5.04%, respectively. Among male physicians smokers were 47.37% (14.29% smoked less than 10 cigarettes, 50.79%--10-20 cigarettes, 34.92%--more than 20 cigarettes a day); 16.54% male physicians smoked earlier, 36.09% never smoked. Relevant percentage for female physicians was 25.99 (38.98, 47.46, 13.56, 13.66 and 60.35, respectively). Among male medical students smokers were 58.6% (29.2% less than 10 cigarettes a day, 55.8%--0-20, 14.9%--more than 20 cigarettes a day); 9.1% smoked earlier, 32.3% never smoked. Among female medical students smokers were 20.3% (70.9, 21.5, 7.6, 9.3 and 70.4%, respectively). CONCLUSION: Tobacco smoking depends on education and marital status. Both in men and women the least number of smokers are among persons with higher education and married ones.     

Smoking-related health behaviors of employees and readiness to quit: basis for health promotion interventions.

This report describes patterns of cigarette smoking and interest in smoking cessation programs among employees in a public worksite (n = 6,000) and a private worksite (n = 14,000). Of the 622 employees who attended an employee assistance program (EAP) orientation, 110 (18%) were current smokers. A significantly greater proportion of public employees smoked cigarettes, smoked more heavily, and evaluated their health more poorly compared to private employees. Smokers in both sites were over-represented in unskilled positions. Regardless of worksite, respondents who smoked had similar desires to quit or cut down and were annoyed by the comments of others, felt guilty about smoking, awakened with a desire to smoke, and felt they had a smoking problem. Overall, more than one third of individuals were interested in joining a smoking cessation program. Occupational health nurses may use these findings to design and implement smoking cessation interventions in their workplaces.     

Nasal spray nicotine replacement suppresses cigarette smoking desire and behavior.

The effects of short-term nasal spray nicotine replacement in suppressing desire to smoke and ad libitum cigarette smoking behavior were evaluated in male and female smokers. In study I, 10 male and 10 female smokers received intermittent doses of 0, 7.5, 15, and 30 micrograms/kg nicotine by way of measured-dose nasal spray, with each dose on a separate day. Self-reported desire to smoke was significantly suppressed by each nicotine dose compared with placebo, but there were no significant differences among nicotine doses or between men and women. In study II, eight male and eight female smokers received 0, 15, and 30 micrograms/kg nicotine intermittently and were allowed to smoke their preferred brands of cigarettes ad libitum. Similar to study I, nicotine replacement significantly suppressed number of cigarettes smoked, number of puffs, and carbon monoxide boost and increased latency to smoking, but there were almost no significant differences between the two nicotine doses. Magnitude of smoking suppression attributable to 15 micrograms/kg tended to be greater in men than in women. However, plasma nicotine concentrations were significantly higher after 15 and 30 micrograms/kg versus placebo, suggesting only partial compensation in smoking behavior with short-term nasal nicotine replacement. These findings support the idea that short-term nicotine replacement decreases smoking desire and behavior, but the findings indicate that smoking behavior is partly influenced by factors other than nicotine regulation.     

Relationship between smoking status and serum lipids in a hyperlipidemic population and analysis of possible confounding factors.

The aim of our study was to estimate the potential relationship between smoking behavior and other coronary heart disease risk factors in 250 hyperlipidemic patients. We present data obtained through self-reporting of the number of cigarettes smoked per day, measurements of three tobacco markers, and data on dietary habits and lipid variables. We measured cotinine (by HPLC) and thiocyanate and used a recent colorimetric assay for the indirect evaluation of the nicotine metabolites in a single urine specimen. Mean values of nicotine metabolites, expressed as cotinine equivalents, were 6.7, 39.9, and 79.4 mumol/L, respectively, for nonsmokers, light smokers (7.7 cigarettes per day), and heavy smokers (25.8 cigarettes per day). We found that light smokers have higher concentrations of cotinine and nicotine metabolites in proportion to the number of cigarettes smoked per day than do heavy smokers. Thus, the simple colorimetric assay can accurately evaluate smoking status. Hyperlipidemia and smoking are linked by an intricate network of multiple relations. The concentration of high-density lipoprotein (HDL) cholesterol is lower in heavy smokers, and the concentrations of triglycerides and cholesterol are higher. The 0.11 mmol/L difference in HDL cholesterol between light and heavy smokers is close to the results of previous papers; however, when gender, dietary habits (including alcohol intake), and data on body mass index are included in a multiple regression analysis, there is no longer an association between HDL cholesterol concentrations and smoking status. Therefore, these different dietary habits may be confounding factors that partly explain the pattern of lipid variables.     

Ethnicity predicts perceptions of smoking and smoking cessation among veterans

The objective of this study was to determine if race/ethnicity predicts motivation to quit smoking and preferences for cessation services among smokers serviced by a primarily psychiatric Veterans Affairs hospital. A self-administered survey was given to a convenience sample of smokers (n=146) at the Battle Creek Veterans Affairs Medical Center. Univariate, bivariate and multivariate regression analyses were calculated to determine the association between race/ethnicity and motivation to quit smoking. Forty-two per cent of the sample was non-white. Non-white patients smoked significantly less cigarettes per day as compared with white patients (P=0.002). In the multivariate analyses, compared with whites, non-whites had 3.5 times greater odds of thinking that quitting smoking was extremely/very important to health (P= 0.01), 4.0 times greater odds of thinking of quitting using tobacco products in the next 30 days (P=0.004) and 3.4 times greater odds of being interested in receiving smoking cessation services (P=0.007). Yet, non-white patients were less likely to be interested in intensive nurse counselling and cessation medications. As the number of non-whites continues to increase in the military, novel strategies may be needed to capitalize on the high motivation to quit smoking and preference for non-traditional interventions among non-white smokers treated in Veterans Affairs hospitals.     

Smoking Status Among Women in Households With Young Children

purpose . To identify sociodemographic and health-related correlates of smoking status among women in households with young children.
design . A secondary analysis of the 1992 California Behavioral Risk Factor Surveillance System public-use data tape
participants . Women (N = 520) in households with very young children (≤ 5 years of age)
main outcome measures . Current smoking status
results . Approximately 18% were current smokers; more than 40% smoked more than 10 cigarettes each day. A majority of smokers indicated a high level of nicotine addiction, but had plans to quit. Smoking prevalence varied by sociodemographic variables with higher rates for unmarried, less than college educated, and unemployed participants. Health status also was related to smoking, with higher rates among those with poor health and those limited in activities.
conclusions . Smoking is one way of coping with the stressors of daily life, including those associated with caring for young children. Special cessation efforts may be needed for the unemployed, the unmarried woman, and for those in poor health.     

The smoking behaviour of military nurses: the relationship to job stress, job satisfaction and social support

Three hundred and seven nurses at a large military medical centre were sent and completed an anonymous questionnaire which measured their smoking status along with job stress, job satisfaction and social support, as well as a variety of demographic factors. Three groups of nurses were defined on the basis of their response to the smoking status questions: those who have never smoked (54%), former smokers (23%) and current smokers (22%). The results revealed that the current smokers reported significantly (P less than 0.05) more job stress, job dissatisfaction and less social support than either former smokers or those who had never smoked. Further, the former smokers reported significantly less social support, defined from a variety of perspectives, than those who had never smoked. These were not as important in predicting amount smoked (number of cigarettes per day) among the current smoker group as they were in predicting differences between the different smoking status groups. The results suggest the need to incorporate the issues of social support and to a lesser extent job stress/satisfaction issues into smoking cessation programmes aimed at this population.     

Smoking Habits of Emergency Department Patients: An Opportunity for Disease Prevention

Objective: To determine smoking habits, levels of addiction, readiness to quit, and access to primary care among ED patients.
Methods: A questionnaire was administered prospectively to all non-critical adult patients who presented to one university hospital ED during 23 randomly selected four-hour time blocks; 336 (89%) of 376 eligible patients responded. Self-reported smoking was validated by carbon monoxide breath testing in a pilot sample of 49 patients.
Results: The study patients were mostly young (mean age = 35 ± 15 years), female (59%), white (62%), and high school-educated (73%). Of the 336 ED patients, 41% were current smokers (95% CI = 0.36–0.46); 42% of these were "moderately" to "very highly" dependent on nicotine (Fagerstrom Test for Nicotine Dependence > 4). Of those who smoked, 68% stated they wanted to quit, and 49% wanted to quit within the month. Fifty-six percent of all those who smoked stated that they had never been told to quit smoking by any physician. Thirty-five percent of the ED sample (118 patients) relied upon EDs for most or all of their routine, primary health care; 55% (95% CI = 0.46–0.64) of these patients were current smokers.
Conclusions: The prevalence rates of smoking and nicotine addiction among ED patients are high. Almost half of ED smokers are ready to quit, but most state they have never been told by a physician to do so. Finally, a large proportion of ED smokers receive their primary care in EDs. Therefore, the ED may be an underused setting for smoking cessation intervention.     

A computerized smoking cessation intervention for high school smokers

This study evaluated a computerized intervention designed to assist high school-aged smokers to consider not smoking and move forward in the "Stages of Change." A pretest-posttest pilot was conducted with 121 high school students who completed self-reported questionnaires that provided information about smoking history and exposure, smoking dependence, stage of change, and social support. Following baseline assessment, the experimental group (n = 61) completed four, 30-minute computerized sessions known as the Computerized Adolescent Smoking Cessation Program (CASCP). Immediately following completion of the program and 1 month later, the experimental subjects were reassessed. Control subjects completed baseline assessment and were reassessed 4 to 5 weeks later. CASCP increased the number of quit attempts. At 1 month after the intervention, 20% of the experimental group quit smoking. Of those subjects who did not quit smoking, nicotine dependence and the number of cigarettes smoked daily decreased, which decreased their nicotine dependence. Overall, there was a forward movement in the experimental group's stage of change. CASCP was found to be an effective and inexpensive intervention that motivates adolescent smokers to consider smoking cessation, move forward in the stage of change, and decrease nicotine dependence.     

Successful implementation of a no-smoking policy

Literature suggests that positive behavioural changes occur among employees after the introduction of a no-smoking policy (NSP). This paper reports successful results following the introduction of a revised NSP at Hawker de Havilland Victoria (HDHV) Limited, an aerospace component manufacturing company.In February, 1994 a poll survey indicated that 86 of the 480 employees smoked. In April, 1994 all 480 employees were surveyed, to assess smoking behaviour and attitudes. Education programs and company-sponsored Fresh Start Quit courses were conducted on-site.In August, 1994 a second survey was distributed, to the smokers only, to assess smoking habits, behaviour, satisfaction with the NSP and whether education programs influenced them to change their smoking habits.Findings in this study suggest that the introduction of the NSP and education programs induced positive behavioural and attitudinal changes to smoking.In August, 1994 the key results of the second smoking survey indicated that 5 per cent of employees quit smoking, 43 per cent reduced the number of cigarettes smoked per day, 1.6 per cent smoked more and 30 per cent reported no change. These results show that a short-term multifaceted smoking cessation program implemented over 5 months can produce a decrease in cigarette smoking.     

Lower quit rates among African American and Latino menthol cigarette smokers at a tobacco treatment clinic

Background: Lower rates of smoking cessation and higher rates of lung cancer in African American (AA) smokers may be linked to their preference for mentholated cigarettes. Aim: This study assessed the relationship between menthol smoking, race/ethnicity and smoking cessation among a diverse cohort of 1688 patients attending a specialist smoking cessation service. Results: 46% of the patients smoked mentholated cigarettes, but significantly more AA (81%) and Latino (66%) patients than Whites (32%) smoked menthols. AA and Latino menthol smokers smoked significantly fewer cigarettes per day (CPD) than non‐menthol smokers (15.7 vs. 20.3, for AA, and 17.0 vs. 22.1, for Latinos), with no differences among White menthol and non‐menthol smokers. At 4‐week follow up, AA, Latino and White non‐menthol smokers had similar quit rates (54%, 50% and 50% respectively). In contrast, among menthol smokers, AAs and Latinos had lower quit rates (30% and 23% respectively) compared with Whites (43%, p < 0.001). AA and Latino menthol smokers had significantly lower odds of quitting [odds ratio (OR) = 0.34; 95% CI = 0.17, 0.69 for AA, and OR = 0.32; 95% CI = 0.16, 0.62 for Latinos] than their non‐menthol counterparts. At 6‐month follow up, a similar trend was observed for the race/ethnicity subgroups, with AA menthol smokers having half the odds of being abstinent compared with AA non‐menthol smokers (OR = 0.48; 95% CI = 0.25, 0.9). Conclusions: Despite smoking fewer CPD, AA and Latino menthol smokers experience reduced success in quitting as compared with non‐menthol smokers within the same ethnic/racial groups.     

Clinical implications of smoking and aging: breaking through the barriers

In the United States, there are almost 4 million smokers older than 65. Yet, older smokers often receive suboptimal care. Inaccurate information and myths about older smokers may have become ingrained in the attitudes and beliefs of both older smokers and health care providers. In this article, prominent myths about older smokers will be explored and refuted. The realities include the following: Smoking tobacco has no benefit; it does not improve cognition or mood; smoking cessation, even among older, frail adults, produces significant benefits in terms of health and quality of life; and using filtered cigarettes or reducing the number of cigarettes smoked per day does not reduce harm. Gerontological nurses are at the forefront of treating tobacco use among older smokers. They should assess the smoking status of all older adults at every contact, treat smokers with pharmacotherapy and counseling, follow up with patients, and stay informed.     

Admission to a psychiatric unit and changes in tobacco smoking

Smoking and withdrawal from smoking complicates the assessment and treatment of mental illness. We aimed to establish whether psychiatric inpatients smoke different amounts after admission than beforehand and, if so, to find out why. Forty-three inpatients on a working age adult psychiatry ward completed self-report questionnaires about smoking habits. Those who smoked a different amount after admission had a follow-up interview to find out why they thought this had occurred. The interview incorporated qualitative and quantitative aspects which were analysed accordingly.Fifty-six percent of participants were smokers before admission, rising to 70% afterwards. Of the smokers, 17% smoked less after admission, and 63% smoked more. The average number of cigarettes smoked per person per day increased from five to thirteen. The main reasons for smoking more were boredom, stress and the wish to socialise.     

GPs have key role in helping patients to stop smoking

Eighteen per cent of all deaths in adults aged 35 or over in England are still attributable to smoking. Almost all these premature deaths could be avoided if smokers stopped before their mid-thirties but only a quarter of people who have ever smoked regularly manage to quit by this age. Advice from the patient's GP is one of the most important triggers to a smoker making an attempt to quit. All patients attending a surgery for any reason who have smoked within the past three years should be offered advice on stopping smoking. Smokers without smoking-related diseases are just as likely to respond to advice as those with them. It is also important to re-assess the status of former smokers who were recorded as having stopped within the past three years. Half of those who stopped six months ago will relapse at some point as will 40% of those who stopped a year ago. Offer help with stopping to all smokers. The National Centre for Smoking Cessation and Training has launched a new online training module on how GPs can best deliver smoking cessation support to their patients. Optimum treatment involves behavioural support plus one of the smoking cessation medications. Behavioural support includes a number of specific behaviour change techniques that enhance the smoker's chances of remaining abstinent. These include: measurement of carbon monoxide in expired air; advice on best use of medication and helping smokers to put in place a clear 'not a puff' rule.     

Adolescent smoking prevention--primary health care in cooperation with local schools. A controlled intervention study

OBJECTIVE: To evaluate a secondary school smoking prevention program in a small rural Norwegian municipality. DESIGN: The project applied grade specific intervention strategies to all students grades 6-9 and comprised a total of 32 lessons over a period of 3 years, with high student activity. A non-randomised control group was constituted by all 6th-9th grade students in municipalities of similar characteristics in the same county. Results were recorded in annual class-based surveys. SUBJECTS: The intervention group totalled 187 and the control group 364 students. MAIN OUTCOME MEASURES: Prevalence of daily and occasional smoking and number of cigarettes smoked, during the intervention period. RESULTS: An 80% lower rate of daily smoking and 50% fewer cigarettes smoked by daily smokers. Lower rates of smoking in 9th grade occurred mostly among girls. CONCLUSION: The project resulted in a lower recruitment of daily smokers up to grade 9, as well as fewer cigarettes smoked by daily smokers. The intervention was more successful among girls than boys.
