Smoking prevention intervention with school classes in university hospital by thoracic surgeon und pulmonologist. The Zurich prevention project. Prev Med Rep 2022; 29:101964. [PMID: 36161129 PMCID: PMC9502329 DOI: 10.1016/j.pmedr.2022.101964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 08/17/2022] [Accepted: 08/25/2022] [Indexed: 11/20/2022] Open
Abstract
Smoking prevention for scholars by lung specialists in hospital is feasible. The intervention program for pupils on health effects of smoking is well received. The interview with a lung transplant recipient and lung function testing are highly rated. Smoking prevention doubles smoking-related knowledge of scholars aged 10–16.
Smoking prevention in schoolchildren to inform and prevent smoking initiation has been widely studied; however, the potential effect of interventions provided in a hospital setting is unknown. An intervention program named “Schoolchildren smoking prevention in the hospital” was developed in which the health aspects of smoking and its individual consequences were presented in an interactive informational event provided by a thoracic surgeon and a pulmonologist. We aimed to assess the feasibility and the short-term effect of smoking-related knowledge improvement in schoolchildren in a hospital setting. Scholars of 45 classes in Canton of Zurich in Switzerland filled in an anonymous 5-item questionnaire with questions on general knowledge about smoking. The answers were evaluated in this prospective observational cohort study. The primary endpoint was to compare the knowledge improvement by interpretation of answers before-and-after the smoking prevention intervention. Additionally, the performance of children was compared after setting up an overall score and specific subgroups according to gender and school-level. Between Jan 2010, and Oct 2019, schoolchildren aged 10 to 16 years participated in this intervention program and completed the questionnaire before (N = 1270) and after (N = 1264) the intervention. The amount of correctly answered questions increased from 40% (±20) before to 81% (±17), p < 0·0001 after the educational session. An intervention program on health effects of smoking provided by lung specialists in the hospital is feasible, well received, leads to a substantial increase of knowledge, and hopefully can be further explored in the development of smoking prevention programs for schoolchildren.

Abstract
BACKGROUND Universal tobacco-prevention programs targeting youths usually involve significant adults, who are assumed to be important social influences. Commitment not to use tobacco, or to quit use, as a formal contract between an adolescent and a significant adult is a preventive model that has not been widely practiced or explored and has been formally evaluated even less. In this paper, we present the rationale and protocol for the evaluation of the Swedish Tobacco-free Duo program, a multicomponent school-based program the core of which rests on a formal agreement between an adolescent and an adult. The adolescent's commitment mainly concerns avoiding the onset of any tobacco use while the adult commits to support the adolescent in staying tobacco free, being a role model by not using tobacco themselves. OBJECTIVE To assess (1) whether Tobacco-free Duo is superior to an education-only program in preventing smoking onset among adolescents and promoting cessation among their parents, (2) whether exposure to core components (adult-child agreement) entails more positive effects than exposure to other components, (3) the impact of the program on whole school tobacco use, (4) potential negative side effects, and (5) school-level factors related to fidelity of the program's implementation. METHODS A mixed-design approach was developed. First, a cluster randomized controlled trial was designed with schools randomly assigned to either the comprehensive multicomponent program or its educational component only. Primary outcome at the adolescent level was identified as not having tried tobacco during the 3-year junior high school compulsory grades (12-15 years of age). An intention-to-treat cohort-wise approach and an as-treated approach complemented with a whole school repeated cross-sectional approach was devised as analytical methods of the trial data. Second, an observational study was added in order to compare smoking incidence in the schools participating in the experiment with that of a convenience sample of schools that were not part of the experimental study. Diverse secondary outcomes at both adolescent and adult levels were also included. RESULTS The study was approved by the Umeå Regional Ethics Review Board (registration number 2017/255-31) in 2017. Recruitment of schools started in fall 2017 and continued until June 2018. In total, 43 schools were recruited to the experimental study, and 16 schools were recruited to the observational study. Data collection started in the fall 2018, is ongoing, and is planned to be finished in spring 2021. CONCLUSIONS Methodological, ethical, and practical implications of the evaluation protocol were discussed, especially the advantage of combining several sources of data, to triangulate the study questions. The results of these studies will help revise the agenda of this program as well as those of similar programs.

Abstract
Based on a definition of comprehensive prevention, the author submits prevention actions in alcohol and tobacco related problems to the question: “Education or control, must we choose?” After reviewing the history, the author describes the current panorama of health education actions and control before discussing some methodological and ethical questions concerning the methods and the actors of prevention. He tries to define “prevention ideal” – which must be distinguished from “ideal prevention” and its totalitarian abuse – to introduce the second part of his text which deals with the question of evaluation of the effectiveness of alcohol- and tobacco-related problems prevention. The author confirms the efficacy of control measures, but also shows that education has a certain degree of efficacy, despite the dominant trends in Anglo-Saxons countries. He also shows that education is necessary in the context of many European countries. After discussing the issue of cost-effectiveness ratio, the author emphasise the need for global prevention taking into account cultural and political elements to ensure efficient as well as effective prevention and social acceptance of this prevention.

Incentivised chronic disease management and the inverse equity hypothesis: findings from a longitudinal analysis of Scottish primary care practice-level data. BMC Med 2017; 15:77. [PMID: 28395660 PMCID: PMC5387284 DOI: 10.1186/s12916-017-0833-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Accepted: 03/07/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The inverse equity hypothesis asserts that new health policies initially widen inequality, then attenuate inequalities over time. Since 2004, the UK's pay-for-performance scheme for chronic disease management (CDM) in primary care general practices (the Quality and Outcomes Framework) has permitted practices to except (exclude) patients from attending annual CDM reviews, without financial penalty. Informed dissent (ID) is one component of exception rates, applied to patients who have not attended due to refusal or non-response to invitations. 'Population achievement' describes the proportion receiving care, in relation to those eligible to receive it, including excepted patients. Examination of exception reporting (including ID) and population achievement enables the equity impact of the UK pay-for-performance contract to be assessed. We conducted a longitudinal analysis of practice-level rates and of predictors of ID, overall exceptions and population achievement for CDM to examine whether the inverse equity hypothesis holds true. METHODS We carried out a retrospective, longitudinal study using routine primary care data, analysed by multilevel logistic regression. Data were extracted from 793 practices (83% of Scottish general practices) serving 4.4 million patients across Scotland from 2010/2011 to 2012/2013, for 29 CDM indicators covering 11 incentivised diseases. This provided 68,991 observations, representing a total of 15 million opportunities for exception reporting. RESULTS Across all observations, the median overall exception reporting rate was 7.0% (7.04% in 2010-2011; 7.02% in 2011-2012 and 6.92% in 2012-2013). The median non-attendance rate due to ID was 0.9% (0.76% in 2010-2011; 0.88% in 2011-2012 and 0.96% in 2012-2013). Median population achievement was 83.5% (83.51% in 2010-2011; 83.41% in 2011-2012 and 83.63% in 2012-2013). The odds of ID reporting in 2012/2013 were 16.0% greater than in 2010/2011 (p < 0.001). Practices in Scotland's most deprived communities were twice as likely to report non-attendance due to ID (odds ratio 2.10, 95% confidence interval 1.83-2.40, p < 0.001) compared with those in the least deprived; rural practices reported lower levels of non-attendance due to ID. These predictors were also independently associated with overall exceptions. Rates of population achievement did not change over time, with higher levels (higher remuneration) associated with increased rates of overall and ID exception and more affluent practices. CONCLUSIONS Non-attendance for CDM due to ID has risen over time, and higher rates are seen in patients from practices located in disadvantaged areas. This suggests that CDM incentivisation does not conform to the inverse equity hypothesis, because inequalities are widening over time with lower uptake of anticipatory care health checks and CDM reviews noted among those most in need. Incentivised CDM needs to include incentives for engaging with the 'hard to reach' if inequalities in healthcare delivery are to be tackled.

Abstract
Prevention of tobacco use is critical for primordial prevention of cardiovascular diseases. Low- and middle-income countries such as India face a burgeoning burden of tobacco-related cardiovascular diseases. A focus on adolescents and young people is consistent with a primordial approach to cardiovascular disease prevention and appropriate given the natural history of tobacco use, in regards to its onset and progression. The primordial prevention approach is feasible, because it attempts to bring about behavior change (sustained abstinence for nonusers) at the population level. This paper reviews effective strategies for population-based tobacco control among adolescents including settings-based interventions at school, at home, and in the community, as well as policy and media interventions. It goes on to briefly touch on the pivotal role that medical professionals, particularly cardiologists, play in fortifying such interventions and summarizes some key recommendations based on review of evidence on the effectiveness of these interventions.

Abstract
BACKGROUND Adolescent smoking is still highly prevalent in Denmark. One in four 13-year olds indicates that they have tried to smoke, and one in four 15-year olds answer that they smoke regularly. Smoking is more prevalent in socioeconomically disadvantaged populations in Denmark as well as in most Western countries. Previous school-based programs to prevent smoking have shown contrasting results internationally. In Denmark, previous programs have shown limited or no effect. This indicates a need for developing a well-designed, comprehensive, and multi-component intervention aimed at Danish schools with careful implementation and thorough evaluation.This paper describes X:IT, a study including 1) the development of a 3-year school-based multi-component intervention and 2) the randomized trial investigating the effect of the intervention. The study aims at reducing the prevalence of smoking among 13 to 15-year olds by 25%. METHODS/DESIGN The X:IT study is based on the Theory of Triadic Influences. The theory organizes factors influencing adolescent smoking into three streams: cultural environment, social situation, and personal factors. We added a fourth stream, the community aspects. The X:IT program comprises three main components: 1) smoke-free school premises, 2) parental involvement including smoke-free dialogues and smoke-free contracts between students and parents, and 3) a curricular component. The study encompasses process- and effect-evaluations as well as health economic analyses. Ninety-four schools in 17 municipalities were randomly allocated to the intervention (51 schools) or control (43 schools) group. At baseline in September 2010, 4,468 year 7 students were eligible of which 4,167 answered the baseline questionnaire (response rate = 93.3%). DISCUSSION The X:IT study is a large, randomized controlled trial evaluating the effect of an intervention, based on components proven to be efficient in other Nordic settings. The X:IT study directs students, their parents, and smoking prevention policies at the schools. These elements have proven to be effective tools in preventing smoking among adolescents. Program implementation is thoroughly evaluated to be able to add to the current knowledge of the importance of implementation. X:IT creates the basis for thorough effect and process evaluation, focusing on various social groups. TRIAL REGISTRATION Current Controlled Trials ISRCTN77415416.

Abstract
Many modalities of tobacco use prevention programming have been implemented including various policy regulations (tax increases, warning labels, limits on access, smoke-free policies, and restrictions on marketing), mass media programming, school-based classroom education, family involvement, and involvement of community agents (i.e., medical, social, political). The present manuscript provides a glance at these modalities to compare relative and combined impact of them on youth tobacco use. In a majority of trials, community-wide programming, which includes multiple modalities, has not been found to achieve impacts greater than single modality programming. Possibly, the most effective means of prevention involves a careful selection of program type combinations. Also, it is likely that a mechanism for coordinating maximally across program types (e.g., staging of programming) is needed to encourage a synergistic impact. Studying tobacco use prevention as a complex system is considered as a means to maximize effects from combinations of prevention types. Future studies will need to more systematically consider the role of combined programming.

Abstract
BACKGROUND Smoking in pregnancy is a substantial public health problem. When used by non-pregnant smokers, pharmacotherapies [nicotine replacement therapy (NRT), bupropion and varenicline] are effective treatments for smoking cessation, however, their efficacy and safety in pregnancy remains unknown. OBJECTIVES To determine the efficacy and safety of smoking cessation pharmacotherapies, including NRT, varenicline and bupropion (or any other medications) when used to support smoking cessation in pregnancy. SEARCH METHODS We searched the Pregnancy and Childbirth Group's Trials Register (5 March 2012), checked references of retrieved studies and contacted authors in the field. SELECTION CRITERIA Randomised controlled trials (RCTs) with designs that permit the independent effects of any type of NRT (e.g. patch, gum etc.) or any other pharmacotherapy on smoking cessation to be ascertained were eligible for inclusion. Trials must provide very similar (ideally identical) levels of behavioural support or cognitive behaviour therapy (CBT) to participants in active drug and comparator trial arms.The following RCT designs are considered acceptable.Placebo RCTs: any form of NRT or other pharmacotherapy, with or without behavioural support/CBT, or brief advice compared with placebo NRT and additional support of similar intensity.RCTs providing a comparison between i) behavioural support/CBT or brief advice and ii) any form of NRT or other pharmacotherapy added to behavioural support of similar (ideally identical) intensity.Parallel- or cluster-randomised design trials are eligible for inclusion. However, quasi-randomised, cross-over and within-participant designs are not eligible for inclusion due to the potential biases associated with these designs. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias and extracted data. Two assessors independently extracted data and cross checked individual outcomes of this process to ensure accuracy. The primary efficacy outcome was smoking cessation in later pregnancy (in all but one trial, at or around delivery); safety was assessed by seven birth outcomes that indicated neonatal well being and we also collated data on adherence. MAIN RESULTS Six trials of NRT enrolling 1745 pregnant smokers were included; we found no trials of varenicline or bupropion. No statistically significant difference was seen for smoking cessation in later pregnancy after using NRT as compared to control (risk ratio (RR) 1.33, 95% confidence interval (CI) 0.93 to 1.91, six studies, 1745 women). Subgroup analysis comparing placebo-RCTs with those which did not use placebos found that efficacy estimates for cessation varied with trial design (placebo RCTs, RR 1.20, 95% CI 0.93 to 1.56, four studies, 1524 women; non-placebo RCTs, RR 7.81, 95% CI 1.51 to 40.35, two studies, 221 women; P value for random-effects subgroup interaction test = 0.03). There were no statistically significant differences in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care or neonatal death between NRT or control groups. AUTHORS' CONCLUSIONS Nicotine replacement therapy is the only pharmacotherapy for smoking cessation that has been tested in RCTs conducted in pregnancy. There is insufficient evidence to determine whether or not NRT is effective or safe when used to promote smoking cessation in pregnancy or to determine whether or not using NRT has positive or negative impacts on birth outcomes. Further research evidence of efficacy and safety is needed, ideally from placebo-controlled RCTs that investigate higher doses of NRT than were tested in the included studies.

Abstract
BACKGROUND Preventive approaches to health are disproportionately accessed by the more affluent and recent health improvement policy advocates the use of targeted preventive primary care to reduce risk factors in poorer individuals and communities. Outreach has become part of the health service response. Outreach has a long history of engaging those who do not otherwise access services. It has, however, been described as eclectic in its purpose, clientele and mode of practice; its effectiveness is unproven.Using a primary prevention programme in the UK as a case, this paper addresses two research questions: what are the perceived problems of non-engagement that outreach aims to address; and, what specific mechanisms of outreach are hypothesised to tackle these. METHODS Drawing on a wider programme evaluation, the study undertook qualitative interviews with strategically selected health-care professionals. The analysis was thematically guided by the concept of 'candidacy' which theorises the dynamic process through which services and individuals negotiate appropriate service use. RESULTS The study identified seven types of engagement 'problem' and corresponding solutions. These 'problems' lie on a continuum of complexity in terms of the challenges they present to primary care. Reasons for non-engagement are congruent with the concept of 'candidacy' but point to ways in which it can be expanded. CONCLUSIONS The paper draws conclusions about the role of outreach in contributing to the implementation of inequalities focused primary prevention and identifies further research needed in the theoretical development of both outreach as an approach and candidacy as a conceptual framework.

Abstract
BACKGROUND Cigarette smoking is one of the leading causes of preventable death in the world. Decisions to smoke are often made within a broad social context and therefore community interventions using coordinated, multi-component programmes may be effective in influencing the smoking behaviour of young people. OBJECTIVES To determine the effectiveness of multi-component community based interventions in influencing smoking behaviour, which includes preventing the uptake of smoking in young people. SEARCH STRATEGY The Tobacco Addiction group's specialised register, Medline and other health, psychology and public policy electronic databases were searched, the bibliographies of identified studies were checked and raw data was requested from study authors. Searches were updated in August 2010. SELECTION CRITERIA Randomized and non randomized controlled trials that assessed the effectiveness of multi-component community interventions compared to no intervention or to single component or school-based programmes only. Reported outcomes had to include smoking behaviour in young people under the age of 25 years. DATA COLLECTION AND ANALYSIS Information relating to the characteristics and the content of community interventions, participants, outcomes and methods of the study was extracted by one reviewer and checked by a second. Studies were combined in a meta-analysis where possible and reported in narrative synthesis in text and table. MAIN RESULTS Twenty-five studies were included in the review and sixty-eight studies did not meet all of the inclusion criteria. All studies used a controlled trial design, with fifteen using random allocation of schools or communities. One study reported a reduction in short-term smoking prevalence (twelve months or less), while nine studies detected significant long-term effects. Two studies reported significantly lower smoking rates in the control population while the remaining thirteen studies showed no significant difference between groups. Improvements were seen in secondary outcomes for intentions to smoke in six out of eight studies, attitudes in five out of nine studies, perceptions in two out of six studies and knowledge in three out of six studies, while significant differences in favour of the control were seen in one of the nine studies assessing attitudes and one of six studies assessing perceptions. AUTHORS' CONCLUSIONS There is some evidence to support the effectiveness of community interventions in reducing the uptake of smoking in young people, but the evidence is not strong and contains a number of methodological flaws.

Abstract
The causes of stillbirths are inseparable from the causes of maternal and neonatal deaths. This report focuses on prevention of stillbirths by scale-up of care for mothers and babies at the health-system level, with consideration for effects and cost. In countries with high mortality rates, emergency obstetric care has the greatest effect on maternal and neonatal deaths, and on stillbirths. Syphilis detection and treatment is of moderate effect but of lower cost and is highly feasible. Advanced antenatal care, including induction for post-term pregnancies, and detection and management of hypertensive disease, fetal growth restriction, and gestational diabetes, will further reduce mortality, but at higher cost. These interventions are best packaged and provided through linked service delivery methods tailored to suit existing health-care systems. If 99% coverage is reached in 68 priority countries by 2015, up to 1·1 million (45%) third-trimester stillbirths, 201 000 (54%) maternal deaths, and 1·4 million (43%) neonatal deaths could be saved per year at an additional total cost of US$10·9 billion or $2·32 per person, which is in the range of $0·96-2·32 for other ingredients-based intervention packages with only recurrent costs.

Abstract
O objetivo do estudo foi avaliar a efetividade de um programa educacional sobre tabagismo desenvolvido pelo Instituto Nacional do Câncer em adolescentes escolares de Pelotas, RS. Das 46 escolas públicas da cidade, 32 foram sorteadas aleatoriamente e, posteriormente, randomizadas em grupo controle ou intervenção. Em ambas as fases do estudo (pré e pós-intervenção), os estudantes de 7ª e 8ª série responderam a um questionário, e uma amostra de urina foi coletada para análise de cotinina. A intervenção educativa teve duração de seis meses. Os desfechos estudados foram: "auto-relato de uso de cigarros nos últimos 30 dias" e "concentração de cotinina na urina (categorizada em > 10 ng/ml e > 30 ng/ml)". A intervenção não provocou mudança na prevalência de tabagismo, tanto mensurado por auto-relato como pela concentração de cotinina. No entanto, o conhecimento dos alunos acerca dos malefícios do cigarro aumentou no grupo intervenção. Em resumo, não houve efetividade da intervenção educacional para mudanças de comportamento, mas houve melhora no conhecimento dos prejuízos do fumo.

Abstract
The self-concept is recognized as important to both smoking initiation and cessation. However, most of extant research has viewed the self-concept as a static, monolithic construct. It has not drawn on contemporary social-cognitive theories of the self-concept, which view the self-concept as a dynamic, multi-faceted cognitive structure that regulates behavior in context. This paper discusses a contemporary social cognitive framework that can be used to understand the role of the self-concept in smoking.

Abstract
School-based prevention programs are an important component of problem gambling prevention, but empirically effective programs are lacking. Stacked Deck is a set of 5-6 interactive lessons that teach about the history of gambling; the true odds and "house edge"; gambling fallacies; signs, risk factors, and causes of problem gambling; and skills for good decision making and problem solving. An overriding theme of the program is to approach life as a "smart gambler" by determining the odds and weighing the pros versus cons of your actions. A total of 949 grade 9-12 students in 10 schools throughout southern Alberta received the program and completed baseline and follow-up measures. These students were compared to 291 students in 4 control schools. Four months after receiving the program, students in the intervention group had significantly more negative attitudes toward gambling, improved knowledge about gambling and problem gambling, improved resistance to gambling fallacies, improved decision making and problem solving, decreased gambling frequency, and decreased rates of problem gambling. There was no change in involvement in high risk activities or money lost gambling. These results indicate that Stacked Deck is a promising curriculum for the prevention of problem gambling.

Abstract
BACKGROUND Several World Health Organisation reports over recent years have highlighted the high incidence of chronic diseases such as diabetes, coronary heart disease and cancer. Contributory factors include unhealthy diets, alcohol and tobacco use and sedentary lifestyles. This paper reports the findings of a review of reviews of behavioural change interventions to reduce unhealthy behaviours or promote healthy behaviours. We included six different health-related behaviours in the review: healthy eating, physical exercise, smoking, alcohol misuse, sexual risk taking (in young people) and illicit drug use. We excluded reviews which focussed on pharmacological treatments or those which required intensive treatments (e.g. for drug or alcohol dependency). METHODS The Cochrane Library, Database of Abstracts of Reviews of Effectiveness (DARE) and several Ovid databases were searched for systematic reviews of interventions for the six behaviours (updated search 2008). Two reviewers applied the inclusion criteria, extracted data and assessed the quality of the reviews. The results were discussed in a narrative synthesis. RESULTS We included 103 reviews published between 1995 and 2008. The focus of interventions varied, but those targeting specific individuals were generally designed to change an existing behaviour (e.g. cigarette smoking, alcohol misuse), whilst those aimed at the general population or groups such as school children were designed to promote positive behaviours (e.g. healthy eating). Almost 50% (n = 48) of the reviews focussed on smoking (either prevention or cessation). Interventions that were most effective across a range of health behaviours included physician advice or individual counselling, and workplace- and school-based activities. Mass media campaigns and legislative interventions also showed small to moderate effects in changing health behaviours.Generally, the evidence related to short-term effects rather than sustained/longer-term impact and there was a relative lack of evidence on how best to address inequalities. CONCLUSIONS Despite limitations of the review of reviews approach, it is encouraging that there are interventions that are effective in achieving behavioural change. Further emphasis in both primary studies and secondary analysis (e.g. systematic reviews) should be placed on assessing the differential effectiveness of interventions across different population subgroups to ensure that health inequalities are addressed.

Abstract
Background Although indicated prevention of depression is available for about 80% of the Dutch population at little or no cost, only a small proportion of those with subthreshold depression make use of these services. Methods A narrative review is conducted of the Dutch preventive services in mental health care, also addressing the problem of low participation rates. We describe possible causes of these low participation rates, which may be related to the participants themselves, the service system, and the communication to the public, and we put forward possible solutions to this problem. Results There are three main groups of reasons why the participation rates are low: reasons within the participants (e.g., not considering themselves as being at risk; thinking the interventions are not effective; or being unwilling to participate because of the stigma associated with depression); reasons within the health care system; and reasons associated with the communication about the preventive services. Possible solutions to increasing the participation rate include organizing mass media campaigns, developing internet-based preventive interventions, adapting preventive interventions to the needs of specific subpopulations, positioning the services in primary care, integrating the interventions in community-wide interventions, and systematically screening high-risk groups for potential participants. Discussion Prevention could play an important role in public mental health in reducing the enormous burden of depression. However, before this can be realized more research is needed to explore why participation rates are low and how these rates can be improved.

Abstract
OBJECTIVE China has about 350 million smokers, more commonly men. Using data from National Health Service Surveys conducted in 1993, 1998 and 2003, we (i) estimated trends in smoking prevalence and cessation according to sociodemographic variables and (ii) analysed cessation rates, quitting intentions, reasons for quitting and reasons for relapsing. METHODS Data were collected from approximately 57 000 households and 200 000 individuals in each survey year. Household members > 15 years of age were interviewed about their smoking habits, quitting intentions and attitudes towards smoking. We present descriptive data stratified by age, sex, income level and rural versus urban residence. FINDINGS In China, current smoking in those > 15 years old declined 60-49% in men and 5-3.2% in women over 1993-2003. The decline was more marked in urban areas. However, heavy smoking (≥ 20 cigarettes daily) increased substantially overall and doubled in men. The average age of uptake also dropped by about 3 years. In 2003, 7.9% of smokers reported intending to quit, and 6% of people who had ever smoked reported having quit. Of former smokers, 40.6% quit because of illness, 26.9% to prevent disease and 10.9% for financial reasons. CONCLUSION Smoking prevalence declined in China over the study period, perhaps due to the combined effect of smoking cessation, reduced uptake in women and selective mortality among men over 40 years of age. However, heavy smoking increased. People in China rarely quit or intend to quit smoking, except at older ages. Further tobacco control efforts are urgently needed, especially in rural areas.

Systematic reviews on tobacco control from Cochrane and the Community Guide: different methods, similar findings. J Clin Epidemiol 2010; 63:596-606.

Abstract
OBJECTIVES To compare the methods and findings of systematic reviews (SRs) on common tobacco control interventions from two organizations: the Cochrane Collaboration ("Cochrane") and the US Task Force for Community Preventive Services ("the Guide"). STUDY DESIGN AND SETTING Literature review. We retrieved all reviews pertaining to tobacco control produced by the Cochrane and the Guide. We identified seven common topics and compared methods and findings of the retrieved reviews. RESULTS There was considerable variability in the designs of included studies and methods of data synthesis. On average, Cochrane identified more studies than did the Guide (Mean 43.7 vs. 19.0), with only limited overlap between sets of included studies. Most Cochrane reviews (71.4%) were synthesized narratively, whereas most Guide reviews (85.7%) were synthesized using a median of effect size. Despite these differences, findings of the reviews yielded substantial agreement. CONCLUSION Cochrane and the Guide conduct SRs on similar tobacco control-related topics differently. The SRs of the two organizations include overlapping, but nonidentical sets, of studies. Still, they usually reach similar conclusions. Identification of all pertinent original studies seems to be a weak point in the SR process. Policy makers should use reviews from both organizations in formulating tobacco control policy.

Abstract
AIM To determine (i) the concordance among recent meta-analyses about which treatments for smoking cessation are efficacious; (ii) the similarity of odds ratios (ORs) across meta-analyses; and (iii) among the validated treatments, the proportion of studies that found higher quit rates. METHODS Computerized literature search for meta-analyses during the last 5 years in PubMed and PsychInfo. Data were extracted from summary tables of overall effect of validated treatments. RESULTS Fourteen meta-analyses agreed 100% on the presence/absence of efficacy of 17 proven treatments. The ORs differed by <0.5 in 72/76 of the comparisons of meta-analyses. Among 37 comparisons in 33 comparisons, >85% of the studies reported numerical superiority for the active treatment. CONCLUSIONS The efficacy of treatments for smoking cessation are extremely reliable. This argues for inclusion of treatment as an essential feature of tobacco control and clinical practice and argues for reimbursement of smoking cessation treatments on a par with other medical and behavioral disorders.

Abstract
BACKGROUND Tobacco smoking in pregnancy remains one of the few preventable factors associated with complications in pregnancy, low birthweight, preterm birth and has serious long-term health implications for women and babies. Smoking in pregnancy is decreasing in high-income countries and increasing in low- to middle-income countries and is strongly associated with poverty, low educational attainment, poor social support and psychological illness. OBJECTIVES To assess the effects of smoking cessation interventions during pregnancy on smoking behaviour and perinatal health outcomes. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (June 2008), the Cochrane Tobacco Addiction Group's Trials Register (June 2008), EMBASE, PsycLIT, and CINAHL (all from January 2003 to June 2008). We contacted trial authors to locate additional unpublished data. SELECTION CRITERIA Randomised controlled trials where smoking cessation during pregnancy was a primary aim of the intervention. DATA COLLECTION AND ANALYSIS Trials were identified and data extracted by one person and checked by a second. Subgroup analysis was conducted to assess the effect of risk of trial bias, intensity of the intervention and main intervention strategy used. MAIN RESULTS Seventy-two trials are included. Fifty-six randomised controlled trials (over 20,000 pregnant women) and nine cluster-randomised trials (over 5000 pregnant women) provided data on smoking cessation outcomes.There was a significant reduction in smoking in late pregnancy following interventions (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.93 to 0.96), an absolute difference of six in 100 women who stopped smoking during pregnancy. However, there is significant heterogeneity in the combined data (I(2) > 60%). In the trials with the lowest risk of bias, the interventions had less effect (RR 0.97, 95% CI 0.94 to 0.99), and lower heterogeneity (I(2) = 36%). Eight trials of smoking relapse prevention (over 1000 women) showed no statistically significant reduction in relapse.Smoking cessation interventions reduced low birthweight (RR 0.83, 95% CI 0.73 to 0.95) and preterm birth (RR 0.86, 95% CI 0.74 to 0.98), and there was a 53.91g (95% CI 10.44 g to 95.38 g) increase in mean birthweight. There were no statistically significant differences in neonatal intensive care unit admissions, very low birthweight, stillbirths, perinatal or neonatal mortality but these analyses had very limited power. AUTHORS' CONCLUSIONS Smoking cessation interventions in pregnancy reduce the proportion of women who continue to smoke in late pregnancy, and reduce low birthweight and preterm birth. Smoking cessation interventions in pregnancy need to be implemented in all maternity care settings. Given the difficulty many pregnant women addicted to tobacco have quitting during pregnancy, population-based measures to reduce smoking and social inequalities should be supported.

Abstract
In this review, we examine randomized controlled trials of community interventions to affect health. The evidence supports the efficacy of community interventions for preventing tobacco, alcohol, and other drug use; several recent trials have shown the benefits of community interventions for preventing multiple problems of young people, including antisocial behavior. However, the next generation of community intervention research needs to reflect more fully the fact that most psychological and behavioral problems of humans are interrelated and result from the same environmental conditions. The evidence supports testing new comprehensive community interventions that focus on increasing nurturance in communities. Nurturing communities will be ones in which families, schools, neighborhoods, and workplaces (a) minimize biologically and socially toxic events, (b) richly reinforce prosocial behavior, and (c) foster psychological acceptance. Such interventions also have the potential to make neighborhoods more sustainable.

Abstract
OBJECTIVES To assess trends in smoking prevalence among Japanese adolescents and to analyze possible causal factors for the decrease in smoking prevalence observed in a 2004 survey. METHODS Nationwide cross-sectional surveys were conducted in 1996, 2000 and 2004. Survey schools, both junior and senior high schools, considered to be representative of the whole of Japan were sampled randomly. Enrolled students were asked to complete a self-reporting anonymous questionnaire on smoking behavior. The questionnaires were collected from 115,814 students in 1996, 106,297 in 2000, and 102,451 in 2004. School principals were asked about the policy of their respective school on smoking restrictions. RESULTS Cigarette smoking prevalence (lifetime, current, and daily smoking) in 2004, based on the completed questionnaires, had decreased relative to previous years in both sexes and in all school grades. The most important trends were: a decrease in smoking prevalence among the fathers and older brothers of the students; an increase in the proportion of students who did not have friends; a decrease in the proportion of current smokers who usually bought cigarettes in stores decreased in 2004, in particular for the oldest boys. An association was found between a lower smoking rate at a school and a smoke-free school policy. CONCLUSIONS Japan has experienced a decrease in the prevalence of smoking among adolescents. A decrease in smoking prevalence among the fathers and older brothers, limitations to minors' access to tobacco, an increase in the proportion of students without friends, and a school policy restricting smoking may have contributed to this decreasing trend.

Abstract
Background With smoking increasingly confined to lower socio-economic groups, the tobacco control community has been urged to identify which population-level tobacco control interventions work in order to help tackle smoking-related health inequalities. Systematic reviews have a crucial role to play in this task. This overview was therefore carried out in order to (i) summarise the evidence from existing systematic reviews of population-level tobacco control interventions, and (ii) assess the need for a new systematic review of primary studies, with the aim of assessing the differential effects of such interventions. Methods Systematic review methods were used to evaluate existing systematic reviews that assessed a population-level tobacco control intervention and which reported characteristics of included participants in terms of at least one socio-demographic or socio-economic factor. Results Nineteen systematic reviews were included. Four reviews assessed interventions aimed at the population level alone, whilst fifteen included at least one primary study that examined this type of intervention. Four reviews assessed youth access restrictions, one assessed the effects of increasing the unit price of tobacco, and six assessed smoking bans or restrictions. Of the eight remaining reviews, six assessed multi-component community based interventions, in which the population-level interventions were part of a wider tobacco control programme, and two assessed the impact of smoking bans or restrictions in reducing exposure to environmental tobacco smoke. We found tentative evidence that the effect of increasing the unit price of tobacco products may vary between ethnic and socio-economic groups, and between males and females. However, differences in the context and the results of different reviews made it difficult to draw any firm conclusions. Few identified reviews explicitly attempted to examine differences in intervention effects between socio-demographic groups. Therefore on the basis of these reviews the potential for smoking bans, and youth access restrictions to decrease social inequalities in smoking remains unknown. Conclusion There is preliminary evidence that increases in the unit price of tobacco may have the potential to reduce smoking related health inequalities. There is a need for equity effects to be explicitly evaluated in future systematic reviews and in primary research assessing the effects of population tobacco control interventions.

Abstract
BACKGROUND Schools in many countries undertake programmes for smoking prevention, but systematic reviews have shown mixed evidence of their effectiveness. Most peer-led approaches have been classroom-based, and rigorous assessments are scarce. We assessed the effectiveness of a peer-led intervention that aimed to prevent smoking uptake in secondary schools. METHODS We undertook a cluster randomised controlled trial of 10 730 students aged 12-13 years in 59 schools in England and Wales. 29 schools (5372 students) were randomly assigned by stratified block randomisation to the control group to continue their usual smoking education and 30 (5358 students) to the intervention group. The intervention (ASSIST [A Stop Smoking In Schools Trial] programme) consisted of training influential students to act as peer supporters during informal interactions outside the classroom to encourage their peers not to smoke. Follow-up was immediately after the intervention and at 1 and 2 years. Primary outcomes were smoking in the past week in both the school year group and in a group at high risk of regular smoking uptake, which was identified at baseline as occasional, experimental, or ex-smokers. Analysis was by intention to treat. This study is registered, number ISRCTN55572965. FINDINGS The odds ratio of being a smoker in intervention compared with control schools was 0.75 (95% CI 0.55-1.01) immediately after the intervention (n=9349 students), 0.77 (0.59-0.99) at 1-year follow-up (n=9147), and 0.85 (0.72-1.01) at 2-year follow-up (n=8756). The corresponding odds ratios for the high-risk group were 0.79 (0.55-1.13 [n=3561]), 0.75 (0.56-0.99 [n=3483]), and 0.85 (0.70-1.02 [n=3294]), respectively. In a three-tier multilevel model with data from all three follow-ups, the odds of being a smoker in intervention compared with control schools was 0.78 (0.64-0.96). INTERPRETATION The results suggest that, if implemented on a population basis, the ASSIST intervention could lead to a reduction in adolescent smoking prevalence of public-health importance.

Abstract
Background Aim: To estimate the impact of smoking restrictions in homes and schools, and tobacco advertising and information on smoking initiation by young people in Ukraine. Methods Data of 609 young people aged 15–29 was taken from the national representative survey conducted in June 2005. Outcome measures: The reported age of cigarette initiation was used to characterize the start of smoking experimentation, and the reported age of daily smoking initiation was considered to be a characteristic of established smoking. Analysis: survival analysis Cox proportional hazard regression models were used. Results Age of smoking initiation was reported by 87% of young men and 61% of young women, the beginning of daily smoking by 71% and 33% respectively. Being frequently exposed to second-hand smoke and having no household smoking restrictions was associated with a higher risk of earlier smoking initiation both for men and women. For women, this risk was associated with age, HR = 0.95, (95% CI 0.91–0.98), that is, younger girls were more likely to smoke their first cigarette earlier in their lifetime. Those women had a higher risk of early smoking initiation who reported to receive tobacco-related information from magazines, HR = 1.40 (1.01–1.92), and outdoor tobacco advertising, HR = 1.99 (1.45–2.75). With both men and women, the risk of establishing daily smoking was higher in those with lower levels of tobacco-related knowledge and less household smoking restrictions. For women, the risk was higher in those who live in larger cities HR = 1.77 (1.10–2.86), and who received information about tobacco smoking from colleagues or friends HR = 1.83 (1.13–2.95). Conclusion Encouraging people to eliminate their homes of tobacco smoke and tobacco advertising bans can be effective measures in preventing the initiation of smoking among young people. Young female smoking initiation is of special concern in Ukraine, since they are more responsive to tobacco marketing and pro-smoking peer influence.

Abstract
PurposeThe purpose of the study is to undertake a formative evaluation of a young person's Smokebuster club and to examine how young people's experience of being a club member can be used to inform the club's future development.Design/methodology/approachAfter seeking and being granted Local Research Ethics Committee approval to undertake the study a postal survey was conducted of all the Smokebusters members (n=2810).FindingsThe response rate achieved was 16 per cent (n=438). Quantitative data analysis showed that the majority of club members who responded to the survey were white, non‐disabled females, aged between 13‐14 years old. The majority of young people surveyed said they had “never smoked and never will” (70.3 per cent, n=308). However, over 6 per cent (n=28) of the young people surveyed said they “currently smoke but would like to give it up”. A wealth of qualitative data was also obtained that gives useful information on how the young people surveyed thought club provision could be improved.Practical implicationsThe findings of this study are thought to be useful not only for future development of the Smokebuster club that is the focus of this evaluation but also for those who organise similar clubs. The findings are also of wider relevance to professionals engaged in smoking cessation initiatives for young people.Originality/valueThe value of this paper relates to issues surrounding engaging undertaking young people in such evaluation. Also reports of Smokebuster club evaluations are rarely given in the literature and therefore the findings of this study augment this limited information.

Abstract
BACKGROUND Teenage smoking prevalence is around 15% in developing countries (with wide variation from country to country), and around 26% in the UK and USA. Although most tobacco control programmes for adolescents are based around prevention of uptake, there are also a number of initiatives to help those who want to quit. Since those who do not smoke before the age of 20 are significantly less likely to start as adults, there is a strong case for programmes for young people that address both prevention and treatment. OBJECTIVES To evaluate the effectiveness of strategies that help young people to stop smoking tobacco. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Tobacco Addiction Group's Specialized Register, MEDLINE, EMBASE, PsyclNFO, ERIC, CINAHL, and the bibliographies of identified trials. We also searched the 'grey' literature (unpublished materials), and contacted authors and experts in the field where necessary. SELECTION CRITERIA Types of studies: Randomized controlled trials, cluster-randomized controlled trials and controlled trials. TYPES OF PARTICIPANTS Young people, aged less than 20, who are regular tobacco smokers. Types of interventions: The interventions ranged from simple ones such as pharmacotherapy, targeting individual young people, through complex programmes targeting people or organizations associated with young people (for example, their families or schools), or the community in which young people live. We included cessation programmes but excluded programmes primarily aimed at prevention of uptake. Types of outcome measures: The primary outcome was smoking status at six months follow up, among those who smoked at baseline. We report the definition of cessation used in each trial (e.g seven- or thirty-day point prevalence abstinence, or sustained or prolonged abstinence), and we preferred biochemically verified cessation when that measure was available. DATA COLLECTION AND ANALYSIS Both authors independently assessed the eligibility of candidate trials identified by the searches, and extracted data from them. We categorized included trials as being at low, medium or high risk of bias, based on concealment of allocation, blinding (where applicable) and the handling of attrition and losses to follow up. We conducted limited meta-analyses of some of the trials, provided that it was appropriate to group them and provided that there was minimal heterogeneity between them. We estimated pooled odds ratios using the Mantel-Haenszel method, based on the quit rates at longest follow up for trials with at least six months follow up from the start of the intervention. MAIN RESULTS We found 15 trials, covering 3605 young people, which met our inclusion criteria (seven cluster-randomized controlled trials, six randomized controlled trials and two controlled trials). Three trials used or tested the transtheoretical model (stages of change) approach, two tested pharmacological aids to quitting (nicotine replacement and bupropion), and the remaining trials used various psycho-social interventions, such as motivational enhancement or behavioural management. The trials evaluating TTM interventions achieved moderate long-term success, with a pooled odds ratio (OR) at one year of 1.70 ( 95% confidence interval (CI) 1.25 to 2.33) persisting at two-year follow up with an OR of 1.38 (95% CI 0.99 to 1.92). Neither of the pharmacological intervention trials achieved statistically significant results (data not pooled), but both were small-scale, with low power to detect an effect. The three interventions (5 trials) which used cognitive behavioural therapy interventions did not individually achieve statistically significant results, although when the three Not on Tobacco trials were pooled the OR 1.87; (95% CI 1.00 to 3.50) suggested some measure of effectiveness. Although the three trials that incorporated motivational interviewing as a component of the intervention achieved a pooled OR of 2.05 (95% CI 1.10 to 3.80), the impossibility of isolating the effect of the motivational interviewing in these trials meant that we could not draw meaningful inferences from that analysis. AUTHORS' CONCLUSIONS Complex approaches show promise, with some persistence of abstinence (30 days point prevalence abstinence at six months), especially those incorporating elements sensitive to stage of change. There were few trials with evidence about pharmacological interventions (nicotine replacement and bupropion), and none demonstrated effectiveness for adolescent smokers. Psycho-social interventions have not so far demonstrated effectiveness, although pooled results for the Not on Tobacco trials suggest that that this approach may yet prove to be effective; however, their definition of cessation (one or more smoke-free days) may not adequately account for the episodic nature of much adolescent smoking. There is a need for well-designed adequately powered randomized controlled trials for this population of smokers, with a minimum of six months follow up and rigorous definitions of cessation (sustained and biochemically verified). Attrition and losses to follow up are particularly problematic in trials for young smokers, and need to be kept to a minimum, so that management and interpretation of missing data need not compromise the findings.

Abstract
With over 600,000 participants in 16 countries, the smokefree class competition is one of the largest smoking prevention programmes in Europe. Participating classes that maintain a smoking prevalence usually below 10% are eligible for a contest and the winner is rewarded with money. There is however no convincing evidence that this competition has any effect on smoking prevalence beyond the short term, and this approach raises serious ethical issues. In particular, the central principle of this competition is to apply negative peer pressure upon teenage smokers. However, promoters of this competition have neglected to report the possible adverse consequences of using negative peer pressure upon smokers. This is a concern, because teenage smokers are more vulnerable than non-smokers, and they are at higher risk of suffering from psychological problems and school failure.

Abstract
BACKGROUND The natural course of onset of cigarette use has been conceptualized as progressing sequentially through 5 stages (preparation, trying, irregular use, regular use, nicotine-dependent smoking). However, recent studies suggest that symptoms of nicotine dependence can occur early in the onset process, raising questions about the validity of this model. The objective of our study was to describe the sequence and timing of 12 milestones (6 related to cigarette use and 6 to symptoms of nicotine dependence) during onset of cigarette use. METHODS Grade 7 students in 10 secondary schools in Montréal (n = 1293) were followed prospectively every 3-4 months for 5 years. Using Kaplan-Meier analysis, we computed the number of months after first puff at which the cumulative probability of attaining each milestone was 25%, among 311 participants who initiated cigarette use during follow-up. RESULTS Inhalation rapidly followed first puff. The cumulative probability of inhalation was 25% at 1.5 months (95% confidence interval [CI] 1.5-2.5). The cumulative probability (and 95% CI) was 2.5 months (1.5-2.5) for mental addiction, 2.5 (1.0-3.0) for smoking a whole cigarette, 4.5 (2.5-8.8) for cravings, 5.4 (3.8-9.7) for physical addiction, 8.8 (7.0-11.9) for monthly smoking, 11.0 (6.4-16.8) for withdrawal symptoms, 13.0 (10.3-20.5) for tolerance, 19.4 (14.5-31.7) for weekly smoking, 19.5 (14.0-23.9) for lifetime total of 100 cigarettes, 23.1 (19.7-37.6) for daily smoking and 40.6 (35.1-56.0) for conversion to tobacco dependence. INTERPRETATION Symptoms of nicotine dependence develop soon after first puff and can precede monthly, weekly and daily smoking. Cessation interventions that manage dependence symptoms may be needed soon after first puff.

Abstract
OBJECTIVES As part of efforts to develop a smoking control strategy for Japanese adolescents, the results of two nationwide surveys on adolescent smoking behaviour were compared. DESIGN Descriptive study on smoking behaviour among high school students was conducted. Self-reporting anonymous questionnaires were administered to 115,814 students in 1996 and 106,297 in 2000 through randomly sampled junior and senior high schools throughout Japan. MAIN OUTCOME MEASURES Smoking prevalence, proportion of smokers by usual sources of cigarettes, national estimated cigarettes consumed by minors, share of cigarette brands smoked by high school students. RESULTS The experiment rate among junior high school boys decreased in 2000 compared with that in 1996, whereas current and daily smoking rates did not. Although prevalence among Japanese girls was much lower than that among boys, prevalence among girls increased in 2000. The main source of cigarettes among high school smokers was vending machines. The proportion of smokers who usually purchased cigarettes from vending machines increased in 2000, in spite of the 1998 introduction of restrictions on night-time operations. Japanese adolescents were more likely than adults to smoke American cigarette brands, and the adolescent market share of American brands has increased rapidly, especially for menthol brands. CONCLUSIONS This survey revealed the seriousness of the problem of smoking behaviour among Japanese high school students, and suggested that this behaviour may be influenced by social environmental factors, including the marketing strategies of the tobacco industry. Action should be taken to reduce the prevalence and impact of pro-tobacco marketing messages and to abolish cigarette vending machines.

Abstract
Promoting active transport is an increasingly important focus of recent health promotion initiatives addressing the major public health concerns of car dependence, decreased levels of physical activity and environmental health. Using active transport that relies less on the use of private cars and more on alternatives such as walking, cycling and public transport has the potential to increase population levels of physical activity and to improve the environment. Over 12 months, a combined social and individualized marketing campaign was delivered to a cohort of randomly selected health service employees (n = 68) working at a health care facility in inner-city Sydney, Australia. Pre- and post-intervention surveys measured changes in mode of transport, awareness of active transport and attitudes towards mode of transport. Following the intervention, we found there was a reduction in the proportion of participants who drove to work 5 days per week and a decrease in trips travelled by car on weekends. In addition, there was high awareness of the intervention amongst participants and their understanding of the concept of active transport improved from 17.6% at baseline to 94.1% at the follow-up survey (p < 0.01). There was also a significant shift in attitudes, which suggested increased positive regard for active transport. Our findings suggest that a combined social and individualized marketing campaign in the workplace setting can increase the use of active transport for the journey to work and trips on weekends. However, before these findings are widely applied, the intervention needs to be tested in a controlled study with a larger sample size.

Abstract
BACKGROUND Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking. OBJECTIVES To assess the effectiveness of community interventions for reducing the prevalence of smoking. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group specialised register, MEDLINE (1966-August 2001) and EMBASE (1980-August 2001) and reference lists of articles. SELECTION CRITERIA Controlled trials of community interventions for reducing smoking prevalence in adult smokers. The primary outcome was smoking behaviour. DATA COLLECTION AND ANALYSIS Data were extracted by one person and checked by a second. MAIN RESULTS Thirty two studies were included, of which seventeen included only one intervention and one comparison community. Only four studies used random assignment of communities to either the intervention or comparison group. The population size of the communities ranged from a few thousand to over 100,000 people. Change in smoking prevalence was measured using cross-sectional follow-up data in 27 studies. The estimated net decline ranged from -1.0% to 3.0% for men and women combined (10 studies). For women, the decline ranged from -0.2% to + 3.5% per year (n=11), and for men the decline ranged from -0.4% to +1.6% per year (n=12). Cigarette consumption and quit rates were only reported in a small number of studies. The two most rigorous studies showed limited evidence of an effect on prevalence. In the US COMMIT study there was no differential decline in prevalence between intervention and control communities, and there was no significant difference in the quit rates of heavier smokers who were the target intervention group. In the Australian CART study there was a significantly greater quit rate for men but not women. REVIEWER'S CONCLUSIONS The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.
