A longitudinal study of smoking in year 7 and 8 students speaking English or a language other than English at home in Sydney, Australia

OBJECTIVE—To compare the rates and predictors of smoking uptake between adolescents speaking English and those speaking a language other than English (LOTE) at home.
DESIGN—A cross-sectional survey of year 7 and 8 students (aged 12 and 13 years) was conducted in 1994 and repeated 12 months later. A cohort of students was identified with respondents at baseline matched at follow up. χ² and logistic regression were used for analysis.
SETTING—38 schools in southern, east, and northern Sydney, Australia.
SUBJECTS—Year 7 and 8 students in the schools were included and examined on two occasions, with complete data for 5947 (80%) students at baseline and 6177 (98%) students at a 12-month follow up. Records were able to be matched perfectly for 3513 respondents (59%).
MAIN OUTCOME MEASURES—Smoking rates and predictors of smoking uptake among students speaking English or a LOTE at home.
RESULTS—At baseline, 6.1% of students surveyed were smokers. Twelve months later, 15.8% of student surveyed were smokers. There were significantly lower smoking rates among students speaking a LOTE at home compared with those speaking English at home at baseline and at 12 months. Using matched data, for students speaking English at home, five variables were significant predictors of smoking uptake: thinking it acceptable to smoke, perceived benefits of smoking, and having a brother, sister, or close friend who smokes. For students speaking a LOTE, the only predictor was the smoking status of close friends.
CONCLUSIONS—Despite the higher smoking prevalence among men with a non-English-speaking background, and the reported strong association between fathers' smoking status and smoking onset of their children, adolescents speaking a LOTE at home were significantly less likely to be smokers than their English-speaking counterparts. Thus, there would seem to be a delay of smoking onset among students speaking a LOTE at home. The smoking rates among respondents speaking a LOTE at home in this study are lower than those obtained from the studies conducted in Europe and the United States. Effective smoking prevention interventions need to be implemented at an early stage of adolescence.

One-year predictors of smoking initiation and of continued smoking among elementary schoolchildren in multiethnic, low-income, inner-city neighbourhoods

OBJECTIVE—To identify one-year predictors of smoking initiation among never-smokers, and of continued smoking among ever-smokers.
DESIGN—Two sequential cohorts of grade 4 and 5 children. Data were collected as part of Coeur en sante St Louis du Parc, a non-randomised controlled trial to evaluate the impact of a school-based heart health promotion programme.
SETTING—24 inner-city elementary schools located in multiethnic, low-income neighbourhoods in Montreal.
SUBJECT—1824 schoolchildren aged 9-12 years with baseline and one-year follow-up data.
MAIN OUTCOME MEASURES—Changes in smoking behaviour over a year; the ability of baseline data to predict smoking initiation and continued smoking a year later was investigated in logistic regression analyses.
RESULTS—The prevalence of ever-smoking was 21.1% at baseline and 30.2% at one-year follow up. One in six never-smokers initiated smoking; one in three ever-smokers continued smoking. Predictors of initiation included age (odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.3 to 2.0), male gender (OR = 1.5 (95% CI = 1.1 to 2.0)), friends who smoke (OR = 2.3 (95% CI = 1.7 to 3.3)), sibling(s) who smoke (OR = 1.9 (95% CI = 1.2 to 3.1)), father/mother who smokes (OR = 2.2 (95% CI = 1.6 to 3.0)), and frequent high fat/"junk food" consumption (OR = 1.6 (95% CI = 1.1 to 2.1)). Age and friends who smoke were also independent predictors of continued smoking in both genders. In addition, in boys, current smokers at baseline were 2.6 times (95% CI = 1.4 to 5.0) more likely to continue smoking than past smokers. In girls, being overweight was associated with continued smoking (OR = 3.5 (95% CI = 1.6 to 7.6)).
CONCLUSIONS—Smoking prevention programmes should address parental and sibling influences on smoking, in addition to refusal skills training. Among girls, weight-related issues may also be important.

Patterns of smoking, risk factors for smoking, and smoking cessation among Vietnamese men in Massachusetts (United States)

OBJECTIVES—To measure the prevalence and patterns of, and risk factors for, smoking and other tobacco use among Vietnamese men in Massachusetts (United States).
METHODS—Data were obtained via a telephone interview of 774 Vietnamese men in 1994.
DESIGN—Cross-sectional survey administered via telephone in 1994.
SETTING—Massachusetts, United States.
SUBJECTS—Randomly selected Vietnamese men (n = 774).
MAIN OUTCOME MEASURES—Present and past use of tobacco products, knowledge and attitudes regarding tobacco, and risk factors for tobacco use. Results were compared with data from the Massachusetts general population.
RESULTS—Vietnamese men smoked at a rate 1.9 times that of the Massachusetts general men's rate (43% vs 24%). The smoking rate did not decrease with increasing length of residence in the United States. In a logistic regression, risk factors for current smoking were: age in the thirties; history of parental smoking; lower educational level; higher depression score; low level of exercise; lack of health insurance; and geographical origin from the south coast of Vietnam. Smoking cessation declined with increasing depression score. Most smokers (76%) had no plans to quit smoking.
CONCLUSIONS—Vietnamese men smoke at much higher rates than the general population, and are much less likely to be planning cessation. High rates of depression and sociocultural barriers to smoking cessation must be addressed in efforts to reduce tobacco use among this high-risk population.

Non-ceremonial tobacco use among southwestern rural American Indians: the New Mexico American Indian Behavioural Risk Factor Survey

OBJECTIVES—To ascertain non-ceremonial tobacco use among rural American Indians in New Mexico (United States).
DESIGN—A geographically targeted telephone survey.
SETTING—Rural New Mexico.
PARTICIPANTS—American Indian residents aged 18 years and older.
MAIN OUTCOME MEASURES—Prevalence of ever-smokers and current smokers of cigarettes and ever-users and current users of smokeless tobacco, number of cigarettes smoked, and prevalence of cigarette smoking quitting behaviour.
RESULTS—Of the 1266 respondents, 38.5% (95% confidence interval (CI) = 34.5% to 42.1%) reported ever smoking, and 16.3% (95% CI = 13.5% to 19.0%) reported being current smokers. Current smokers averaged 7.6 (95% CI = 6.0 to 9.3) cigarettes per day. Current smoking prevalence was highest among men and lowest among college graduates. Prevalence of smokeless tobacco use was 24.1% for ever-use and 7.2% for current use and showed a strong male predominance of use.
CONCLUSIONS—The prevalence of current smokers among rural American Indians in New Mexico was lower than among American Indians of other regions in the United States, all New Mexicans, and the national population as a whole. Although smoking prevalence was lower among American Indians in New Mexico, variation by sex and education followed the same patterns as reported among American Indians of other regions.

Changes in cigarette smoking among adults in 35 populations in the mid-1980s

OBJECTIVE—To examine changes in the prevalence of cigarette smoking in 35 study populations of the World Health Organisation's MONICA Project.
DESIGN—Data from two independent, community-based surveys conducted, on average, five years apart.
SETTING—Geographically defined populations in 21 countries mainly in eastern and western Europe.
SUBJECTS—Randomly selected men and women aged 25-64 years. Numbers of participants in each study population ranged from 586 to 2817 in each survey.
MAIN OUTCOME MEASURES—Changes in proportions of current smokers, ex-smokers, and never-smokers by age and sex using data collected by standardised methods.
RESULTS—Among men, smoking prevalence decreased in most populations, by three to four percentage points over five years. In Beijing, however, it increased in all age groups—overall by 11 percentage points. Among women there were increases in smoking in about half the populations. The increases were mainly in the age group 35-54 years and often in those populations where smoking prevalence among women has been relatively low.
CONCLUSIONS—Smoking initiation by middle-aged women in parts of southern and eastern Europe and among men of all ages in Beijing is a matter of concern. The various public health measures that have helped to reduce smoking among men in developed countries should be vigorously extended to these other groups now at growing risk of smoking-related disease.

To what extent do parents strive to protect their children from environmental tobacco smoke in the Nordic countries? A population-based study

OBJECTIVE—To assess to what extent Nordic parents strive to protect their children from environmental tobacco smoke (ETS) at home.
DESIGN—A cross-sectional study using an anonymous questionnaire.
SUBJECTS AND SETTING—A stratified, random sample of 5500 households containing a child born during 1992, including 1500 households in Denmark and 1000 households in each of the countries of Finland, Iceland, Norway, and Sweden.
MAIN OUTCOME MEASURES—Smoking status of parents, prevalence and magnitude of weekly ETS exposure, rules regarding smoking in the home.
RESULTS—82% of current smokers reported having tried to change their smoking behaviour for the sake of their children. Of all parents who answered the questionnaire, 75% reported having introduced some rules to limit ETS in their home. In households where at least one parent smoked, 57% reported that children were exposed to ETS at home. Child exposure to ETS was most prevalent in single-parent households and in households in which parents had lower levels of education. However, these parents were not less likely than other smoking parents to report having tried to change their smoking behaviour for the sake of their children.
CONCLUSION—Environmental tobacco smoke at home is still a problem for many children in the Nordic countries. However, most smoking parents reported having made efforts to change their smoking behaviour for the sake of their children; and in approximately half of all households containing at least one daily smoker, parents reported protecting their children from ETS exposure in the home. Although actual exposure may be higher owing to possible under-reporting of ETS, our results indicate a general awareness in the Nordic countries of the potential negative effects of ETS on children.

Worldwide survey of education on tobacco in medical schools

OBJECTIVES—To determine the extent of teaching about tobacco, tobacco-related diseases, and smoking cessation techniques in medical schools around the world; and to ascertain the problems of getting the teaching about tobacco onto the medical curriculum.
DESIGN—Cross-sectional survey. Questionnaires were sent to the 1353 medical schools in 143 countries around the world using the World Health Organization's Directory of Medical Schools. The questionnaire was translated from English into French, Russian, Mandarin, and Japanese.
SUBJECTS—Deans of medical schools worldwide, or their nominees.
MAIN OUTCOME MEASURES—Extent and format of teaching about tobacco in the medical curriculum, objectives and content of the courses on tobacco, and problems encountered in introducing the topic of tobacco.
RESULTS—493 medical schools responded, representing 64% of countries and 36% of schools. Only 12% of medical schools did not cover the topic of tobacco in the medical curriculum. 58% of medical schools taught about tobacco during the teaching of other subjects. 40% taught tobacco by systematically integrating teaching with other modules. 11% had a specific module on tobacco. The medical schools reported on the objectives and content of their courses on tobacco, which commonly included knowledge about tobacco-related diseases and pharmacological issues. Only a third taught about smoking cessation techniques. 22% had encountered problems in introducing the topic of tobacco, and respondents offered solutions to overcome these problems.
CONCLUSIONS—Medical schools need continued encouragement to include tobacco issues in their curricula, with particular emphasis on teaching about smoking cessation techniques.

Mortality attributable to cigarette smoking in Taiwan: a 12-year follow-up study

BACKGROUND—Assessment of the impact of cigarette smoking on mortality helps to indicate the importance of tobacco control in a given country.
OBJECTIVES—To examine the relative risk of dying from various diseases for cigarette smoking and to estimate annual mortality attributable to cigarette smoking in Taiwan.
DESIGN—Prospective cohort study.
SUBJECTS AND SETTING—A cohort of 14 397 male and female residents aged 40 years or older recruited from 12 townships and precincts in Taiwan from 1982 to 1986. Information on cigarette smoking was collected from each subject at local health centres through a standardised personal interview based on a structured questionnaire. They were followed up regularly to determine their vital status until 1994.
MAIN OUTCOME MEASURES—Cox's proportional hazards regression models were used to derive relative risks of cause-specific mortality for current cigarette smokers compared with never-smokers, and to examine dose-response relationships between mortality from various causes and several measures of cigarette smoking (daily consumption, duration, age of initiation, and cumulative smoking in pack-years).
RESULTS—A total of 2552 persons died during the study period. Among men, cigarette smoking was significantly associated with an increased risk of dying from all causes combined (relative risk (RR) = 1.3); cancer of all sites combined (RR = 1.5); cancers of the stomach (RR = 1.9), liver (RR = 2.2), and lung (RR = 3.7); ischaemic heart disease (RR = 1.8); other heart diseases (RR = 1.4); and chronic obstructive pulmonary disease (RR = 1.9). Among women, cigarette smoking was significantly associated with an increased risk of dying from all causes combined (RR = 1.8), cancer of the lung (RR = 3.6), and peptic ulcer (RR = 17.8). The estimated number of deaths attributable to cigarette smoking in Taiwan in 1994 was 8161 (13.9% of total deaths) for men and 1216 (3.3% of total deaths) for women. In the same year cigarette smoking caused 21.3% and 2.9% of cancer deaths in men and women, respectively, in Taiwan.
CONCLUSIONS—Cigarette smoking has a striking impact on overall mortality and deaths from various causes in the Taiwanese population. Tobacco control should be established as the top priority in public health programmes in Taiwan.

Training pharmacists and pharmacy assistants in the stage-of-change model of smoking cessation: a randomised controlled trial in Scotland

OBJECTIVE—To evaluate a training workshop for community pharmacy personnel to improve their counselling in smoking cessation based on the stage-of-change model.
DESIGN—A randomised controlled trial of community pharmacies and pharmacy customers.
SETTING—All 76 non-city community pharmacies registered in Grampian, Scotland, were invited to participate. Sixty-two pharmacies (82%) were recruited.
SUBJECTS—All the intervention pharmacy personnel were invited to attend the training; 40 pharmacists and 54 assistants attended. A total of 492 customers who smoked (224 intervention, 268 controls) were recruited during the 12-month recruitment period (overall recruitment rate 63%).
MAIN OUTCOME MEASURES—The perceptions of customers and pharmacy personnel of the pharmacy support and self-reported smoking cessation rates for the two groups of customers at one, four, and nine months.
RESULTS—The intervention customer respondents were significantly more likely to have discussed stopping smoking with pharmacy personnel, 85% (113) compared with 62% (99) of the controls (p<0.001). The former also rated their discussion more highly; 34% (45) of the intervention customers compared with 16% (25) of the controls rated it as "very useful" (p = 0.048). Assuming non-responders had lapsed, one-month point prevalence of abstinence was claimed by 30% of intervention customers and 24% of controls (p = 0.12); four months' continuous abstinence was claimed by 16% of intervention customers and 11% of controls (p = 0.094); and nine months' continuous abstinence was claimed by 12% of intervention customers and 7% of controls (p = 0.089). These trends in outcome were not affected by potential confounders (sex, age, socioeconomic status, nicotine dependence, and type of nicotine replacement product used) or adjustment for clustering.
CONCLUSIONS—The intervention was associated with increased and more highly rated counselling, and a trend toward higher smoking cessation rates, indicating that community pharmacy personnel have the potential to make a significant contribution to national smoking cessation targets.

Prevalence and correlates of smoking on the roof of the world

OBJECTIVE—To determine the prevalence and correlates of cigarette smoking among adults in high mountain rural areas of northern Pakistan.
DESIGN—Cross sectional survey.
PARTICIPANTS—A sample of 4203 adults (aged 18 years and over) were selected by stratified random sampling from 16 villages.
MAIN OUTCOME MEASURE—Self reported smoking prevalence; age of smoking initiation; daily cigarette consumption and association between current smoking and sociodemographic variables, use of snuff, wine, body mass index, blood pressure, family history of stroke, and hypertension.
RESULTS—614/1406 men (43.7%) and 154/2797 (5.5%) women reported smoking cigarettes. The age standardised prevalence of smoking was 40.5% for men and 6.3% for women. Men were more likely (odds ratio (OR) 6.5, 95% confidence interval (CI) 4.75 to 8.79) to be smokers. Smokers were more likely to use snuff (OR 1.39, 95% CI 1.12 to 1.73), drink wine (OR 3.47, 95% CI 2.81 to 4.29), and were more likely to work as farmers (OR 1.55, 95% CI 1.05 to 2.29) or shopkeepers (OR 2.63, 95% CI 1.67 to 4.14). Individuals with college level education and with desirable body mass index were less likely to smoke (OR 0.55, 95% CI 0.35 to 0.87; OR 0.74, 95% CI 0.57 to 0.96).
CONCLUSION—Cigarette smoking is a major public health problem in this high mountain community of Pakistan, particularly among the male population, the majority of whom begin to smoke quite early in life. A comprehensive tobacco control effort incorporated into the existing community based health infrastructure is needed.

Predictors of smoking cessation among elderly smokers treated for nicotine dependence

OBJECTIVE: To examine outcomes and predictors of smoking cessation among elderly patients treated for nicotine dependence. DESIGN: Retrospective analysis of patients aged 65-82 who received a nicotine dependence consultation at the Mayo Medical Center between 1 April 1988 and 30 May 1992. Patients were contacted by telephone by a trained interviewer six months after the consultation and were sent a follow-up survey in August 1993. SETTING: Mayo Medical Center, Rochester, Minnesota, United States. SUBJECTS: A total of 613 patients (310 men, 303 women) with a mean age of 69.0 (SD 3.5) years were seen during the study period. MAIN OUTCOME MEASURES: Point prevalence self-reported smoking status. Patients were considered abstinent if they self- reported not smoking (not even a puff) during the seven days before contact. RESULTS: At six-month follow up, 24.8% of the 613 patients reported abstinence from smoking. On multivariate analysis, smoking abstinence was more likely if patients were hospitalised at the time of the consultation, married to a non-smoking spouse, very motivated to stop smoking, and reported their longest time of previous abstinence to be less than a day or more than a month. The response rate to the mailed follow-up survey was 69.9% (429 of 613). The mean duration of follow up was 40.0 +/- 13.2 months following the consultation. Of the 429 patients, 103 (24.0%) reported abstinence from smoking and 326 (76.0%) were smoking at six-month follow up. Patients who reported abstinence at six months had a higher cessation rate at the last follow up (76.0%) compared with patients who were smoking at six-month follow up (33.0%, P < 0.001). For patients who were not smoking at six months, no factors were found to significantly predict abstinence at last follow up. For patients who were smoking at six months, factors associated with smoking cessation at last follow up were: more than a year as the longest time off cigarettes before the consultation; counsellor rating of less severe nicotine dependence; and older age at first regular smoking. CONCLUSIONS: Several predictors of smoking cessation were identified in this study which may be useful for tailoring smoking interventions for the elderly.


     

Implementing smoking bans in American hospitals: results of a national survey

OBJECTIVES—To determine how well hospitals complied with the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) tobacco control standards, which required banning smoking in hospital buildings; to explore issues involved in developing and implementing smoking bans; and to ascertain the perceived success of the policies.
DESIGN—Postal survey conducted January through June 1994.
PARTICIPANTS—Stratified random sample of American hospitals surveyed by JCAHO (n = 1055).
MAIN OUTCOME MEASURES—Enacting smoking policies more restrictive than the JCAHO standard; the respondent's judgment of the relative success of the hospital's smoking policy.
RESULTS—More than 96% of hospitals complied with the smoking ban standard; 41.4% enacted policies that were more restrictive than required by JCAHO. Several characteristics were associated with exceeding JCAHO requirements: location in a "non-tobacco state"; having fewer than 100 beds; location in a metropolitan statistical area; having unionised employees; and having no psychiatric or substance abuse unit, favour having the same tobacco policy in psychiatry and substance abuse units as the rest of the hospital. More than 95% of respondents viewed their hospital's policy as successful. The JCAHO requirements and concern for employees' health were the major forces influencing hospitals to go smoke-free. Negative employee morale and lack of acceptance by visitors and patients were the most commonly cited barriers to overcome when implementing smoke-free policies.
CONCLUSIONS—Smoking bans were successfully implemented in American hospitals, with many restricting smoking beyond the JCAHO standard. Other industries wishing to follow hospitals' lead would be most likely to succeed in the context of a social norm favouring a smoking ban and regulation by an outside agency.

Association of environmental tobacco smoke exposure with socioeconomic status in a population of 7725 New Zealanders

OBJECTIVE—To test the hypothesis that environmental tobacco smoke (ETS) exposure is inversely associated with socioeconomic status.
DESIGN—Survey.
SETTING—General community, New Zealand.
PARTICIPANTS—7725 non-smoking adults (volunteer sample of a multi-industry workforce, n = 5564; and a random sample of urban electoral rolls, n = 2161), including 5408 males; mean age 45 years.
MAIN OUTCOME MEASURES—ETS exposure was assessed as self-reported number of hours per week spent near someone who is smoking, and as prevalence of regular exposure to some ETS. Socioeconomic status was assessed as educational level, occupational status, and median neighbourhood household income.
RESULTS—Both measures of ETS exposure were steeply and inversely associated with all three indicators of socioeconomic status (all p<0.0001). Geometric mean ETS exposure ranged from 16 minutes per week among university-educated participants to 59 minutes per week in the second lowest occupational quintile (95% confidence intervals: 14-18 minutes per week and 54-66 minutes per week). The associations with occupational status and educational level were steeper than those with neighbourhood income. The socioeconomic gradients of ETS exposure were steeper among participants aged less than 35 years than among participants aged over 50 years, among men than women, and among Maori than Europeans.
CONCLUSIONS—In this study population, ETS exposure was inversely associated with socioeconomic status. Greater ETS exposure might therefore contribute to the higher risks of disease and death among low socioeconomic groups. These results provide a further rationale for targeting tobacco control measures to people in low socioeconomic groups.

Roll-your-own smoke yields: theoretical and practical aspects

OBJECTIVE—To identify the key parameters that influence smoke yields from roll-your-own (RYO) cigarettes and to compare smoke yields of cigarettes made under laboratory conditions with those made by habitual RYO consumers.
DESIGN AND SETTING—One-way parametric variations in the laboratory-based production of RYO cigarettes complemented by a consumer survey conducted in a busy street at Romford, Essex, United Kingdom.
SUBJECTS—26 habitual RYO consumers.
MAIN OUTCOME MEASURES—Cigarette weights, puff numbers, and yields (carbon monoxide, nicotine, and tar).
RESULTS—Smoke yields vary for specimen changes in weight of tobacco used, paper porosity, and the incorporation of a filter in the cigarette. Yields of cigarettes produced by 26 RYO smokers ranged from 9.9 to 21.0 mg tar per cigarette and from 0.9 to 1.8 mg nicotine per cigarette, and were generally lower than yields of laboratory-produced RYO cigarettes.
CONCLUSIONS—Laboratory studies can provide useful information concerning the parameters that affect smoke yields of RYO cigarettes such as the incorporation of a filter to reduce yields. However, such studies must be complemented by surveys of cigarettes made by actual current RYO smokers. In one such investigation, it was found that the mean tar yields from cigarettes produced by 57% of the smokers were above the current maximum of 15 mg per cigarette for manufactured cigarettes. Currently 8% of manufactured cigarettes in the UK have a declared nicotine yield of greater than 1.1 mg per cigarette whereas 77% of RYO smokers produced cigarettes with a nicotine yield greater than this value.

Smoking prevalence and risk factors for smoking in a population of United States Air Force basic trainees

OBJECTIVE—To provide a comprehensive assessment of smoking prevalence and risks for smoking in an entire population of United States Air Force (USAF) military basic trainees (n = 32 144).
DESIGN—Population-based survey with every individual entering the USAF enlisted force from August 1995 to August 1996.
SETTING—USAF Basic Military Training (BMT) facility at Lackland Air Force Base, Texas. All trainees were assessed during the first week of BMT.
MAIN OUTCOME MEASURES—A 53-item questionnaire was developed to assess four domains: demographics, smoking history, risk factors for smoking, and other health behaviours.
RESULTS—Approximately 32% of the trainees smoked regularly before basic training and a small percentage of the trainees (7.6%) described themselves as ex-smokers. Men, Euro-Americans, and those from lower educational backgrounds were more likely to smoke than other trainees. On average, smokers had smoked for approximately four years and had low nicotine dependence scores. Individuals who had smoked before BMT were more likely to use other drugs (such as alcohol, binge drinking, smokeless tobacco), and were less physically active than never-smokers. These findings were particularly strong for those who smoked up to basic training but were also evident for ex-smokers.
CONCLUSIONS—Smoking is a prevalent risk factor among individuals entering the USAF. Furthermore, smoking was related to other risk factors believed to lower military readiness, including alcohol use and decreased physical activity. Comprehensive tobacco control policies aimed at reducing smoking among military trainees are needed.

Impact of UK National Health Service smoking cessation services: variations in outcomes in England

Objectives: To determine the extent to which UK National Health Service (NHS) smoking cessation services in England reach smokers and support them to quit at four weeks, and to identify which service and area characteristics contribute to observed outcomes.

Design: Ordinary least squares regression was used to investigate local smoking outcomes in relation to characteristics of health authorities and their smoking cessation services.

Setting: 76 health authorities (from a total of 99) in England from April 2000 to March 2001.

Main outcome measures: Reach—number of smokers attending cessation services and setting a quit date as a percentage of the adult smoking population in each health authority. Absolute success—number of smokers setting a quit date who subsequently reported quitting at four weeks (not having smoked between two and four weeks after quit date). Cessation rate—number of smokers who reported quitting at four weeks as a percentage of those setting a quit date. Loss—percentage lost to follow up.

Results: A range of service and area characteristics was associated with each outcome. For example, group support proved more effective than one to one interventions in helping a greater proportion of smokers to quit at four weeks. Services based in health action zones were reaching larger numbers of smokers. However, services operating in deprived communities achieved lower cessation rates than those in more prosperous areas.

Conclusions: Well developed, evidence based NHS smoking cessation services, reflecting good practice, are yielding positive outcomes in England. However, most of the data are based on self reported smoking status at four weeks. It will be important to obtain validated data about continuous cessation over one year or more in order to assess longer term impact.

     

Patterns of smoking in Russia

BACKGROUND—Tobacco is a leading cause of avoidable death in Russia but there is, as yet, relatively little information in the public domain on who is smoking and how this is changing. This information is important for those seeking to develop effective policies to tackle this issue.
OBJECTIVE—To determine the prevalence of smoking in Russia and its association with sociodemographic factors.
DESIGN—Cross-sectional survey on patterns of tobacco consumption.
SETTING—Data were collected using the New Russia Barometer, a multi-stage stratified-sample survey of the population of the Russian Federation undertaken in the summer of 1996.
PARTICIPANTS—Data were available on 1587 individuals (response rate 65.7%). Respondents differed little from the overall Russian population in terms of age, sex, education, and voting intention.
MAIN OUTCOME MEASURES—Prevalence of current and past smoking.
RESULTS—Smoking is common among males of all ages and in all areas. Of those aged 18-24 years, 65% smoke, rising to 73% in those aged 25-34 and then falling steadily to reach 41% in those aged 65 and older. Among women, smoking is much more common among the young (27% in those aged 18-34) than among the middle-aged and elderly (5% in those aged 55 and older), and more common among those living in urban areas than in rural areas. Smoking is also more common among men and women suffering material deprivation but there is no independent association with education. Among men, but not women, church attendance is inversely associated with smoking. In both sexes, but especially women, heavy drinking and smoking are associated.
CONCLUSIONS—Tobacco poses a major threat to the health of future generations in Russia, especially among women. A robust policy response is required.

Impact of the graphic Canadian warning labels on adult smoking behaviour

Objective: To assess the impact of graphic Canadian cigarette warning labels on current adult smokers.

Design: A random-digit-dial telephone survey was conducted with 616 adult smokers in south western Ontario, Canada in October/November 2001, with three month follow up.

Main outcome measures: Smoking behaviour (quitting, quit attempts, and reduced smoking), intentions to quit, and salience of the warning labels.

Results: Virtually all smokers (91%) reported having read the warning labels and smokers demonstrated a thorough knowledge of their content. A strong positive relation was observed between a measure of cognitive processing—the extent to which smokers reported reading, thinking about, and discussing the new labels—and smokers' intentions to quit (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.16; p < 0.001). Most important, cognitive processing predicted cessation behaviour at follow up. Smokers who had read, thought about, and discussed the new labels at baseline were more likely to have quit, made a quit attempt, or reduced their smoking three months later, after adjusting for intentions to quit and smoking status at baseline (OR 1.07, 95% CI 1.03 to 1.12; p < 0.001).

Conclusions: Graphic cigarette warning labels serve as an effective population based smoking cessation intervention. The findings add to the growing literature on health warnings and provide strong support for the effectiveness of Canada's tobacco labelling policy.
