Tobacco use by youth: a surveillance report from the Global Youth Tobacco Survey project

The Global Youth Tobacco Survey (GYTS) project was developed by the World Health Organization and the US Centers for Disease Control and Prevention to track tobacco use among youth in countries across the world, using a common methodology and core questionnaire. The GYTS is school based and employs a two-stage sample design to produce representative data on smoking among students aged 13-15 years. The first stage consists of a probabilistic selection of schools, and the second consists of a random selection of classes from the participating schools. All students in the selected classes are eligible for the survey. In 1999, the GYTS was conducted in 13 countries and is currently in progress in over 30 countries. This report describes data from 12 countries: Barbados, China, Costa Rica, Fiji, Jordan, Poland, the Russian Federation (Moscow), South Africa, Sri Lanka, Ukraine (Kiev), Venezuela, and Zimbabwe. The findings show that tobacco use in the surveyed age group ranged from a high of 33% to a low of 10%. While the majority of current smokers wanted to stop smoking, very few were able to attend a cessation programme. In most countries the majority of young people reported seeing advertisements for cigarettes in media outlets, but anti-tobacco advertising was rare. The majority of young people reported being taught in school about the dangers of smoking. Environmental tobacco smoke exposure was very high in all countries. These results show that the GYTS surveillance system is enhancing the capacity of countries to design, implement, and evaluate tobacco prevention and control programmes.

Patterns of global tobacco use in young people and implications for future chronic disease burden in adults

BACKGROUND Tobacco use is a leading preventable risk factor for many chronic disorders, which are expected to account for an increasing share of the global disease burden. As part of the Global Youth Tobacco Survey (GYTS), we aimed to assess the effect of tobacco use by young people on global mortality. METHODS GYTS is a school-based survey of students aged 13-15 years. The survey was undertaken at 395 sites in 131 countries and the Gaza Strip and West Bank. We questioned students about current tobacco use, susceptibility to smoking among non-smokers, and exposure to secondhand smoke at home and in public places. FINDINGS The difference in current cigarette smoking between boys and girls is narrower than expected in many regions of the world. Use of tobacco products other than cigarettes by students is as high as cigarette smoking in many regions. Almost one in five never-smokers reported they were susceptible to smoking in the next year. Student exposure to secondhand smoke was high both at home (more than four in ten) and in public places (more than five in ten). Never-smokers were significantly less likely than current smokers to be exposed to secondhand smoke at home (prevalence 39.1% [95% CI 36.6-41.6] vs 72.8% [64.0-81.6]) and in public places (49.5% [46.7-52.3] vs 81.2% [74.2-88.2]). INTERPRETATION Our findings are troubling for the future of chronic disease and tobacco-related mortality. Reduction of tobacco consumption will require a redoubling of efforts to prevent initiation and promote cessation among the large proportion of young people who currently use tobacco. High exposure to secondhand smoke suggests a need for countries to pass strong and effective smoke-free policies.

Trends in cigarette smoking among US adolescents, 1974 through 1991.

OBJECTIVES The purpose of this study was to determine national trends in adolescent cigarette smoking prevalence. METHODS We conducted trend analyses based on 1974 through 1991 current smoking prevalence data among persons aged 12 through 19 years from the National Household Surveys on Drug Abuse, High School Seniors Surveys, and National Health Interview Surveys. RESULTS Overall smoking prevalence declined much more rapidly from 1974 through 1980 (1.9 percentage points annually among younger adolescents; the range among surveys of older adolescents was 0.2 to 2.0 percentage points annually) than from 1985 through 1991 (0 to 0.5 percentage points annually among all adolescents). Since 1980, smoking has generally declined at a slightly faster rate among older female adolescents than among male adolescents. Smoking among Black adolescents of all ages declined in nearly every survey population during each study period (range among surveys: 1974-1985 = 1.0 to 2.9 percentage points; 1985-1991 = 0.7 to 1.5 percentage points annually); for White adolescents, only minimal declines in smoking have occurred since 1985. CONCLUSIONS Since 1974, major changes in adolescent smoking patterns have occurred, especially among Blacks. The overall slowing rate of decline in smoking prevalence since 1985 may indicate success of increased tobacco advertising and promotional activities targeted at adolescents or inadequate antitobacco education efforts.

Uncovering the relation between betel quid chewing and cigarette smoking in Taiwan

Objective: To describe the characteristics of betel quid chewers and to investigate the behavioural and mortality relations between betel quid chewing and cigarette smoking. Method: Prevalence and mortality risks of betel quid chewers by smoking status were calculated, based on the National Health Interview Survey in 2001 and a community based cohort, respectively. Cox’s proportional hazards model was used to adjust mortality risks for age, alcohol use, and education. Results: Almost all betel quid chewers were smokers, and most started chewing after smoking. Chewers were predominantly male, mostly in their 30s and 40s, more likely being among the lowest educational or income group, and residing in the eastern regions of Taiwan. On average, betel quid chewers who smoked consumed 18 pieces of betel quid a day, and smoked more cigarettes per day. Far more smokers use betel quid than non-smokers (27.5% v 2.5%), but ex-smokers quit betel quid more than smokers (15.1% v 6.8%). The significantly increased mortality of betel quid users who also smoked, for all causes, all cancer, oral cancer, and cancer of the nasopharynx, lung, and liver, was the result of the combined effects of chewing and smoking. Smokers who chewed betel quid nearly tripled their oral cancer risks from a relative risk of 2.1 to 5.9. Increasing the number of cigarettes smoked among betel quid chewers was associated with a synergistic effect, reflective of the significant interaction between the two. Conclusion: To a large extent, the serious health consequences suffered by betel quid chewers were the result of the combined effects of smoking and chewing. Betel quid chewing should not be considered as an isolated issue, but should be viewed conjointly with cigarette smoking. Reducing cigarette smoking serves as an important first step in reducing betel quid chewing, and incorporating betel quid control into tobacco control may provide a new paradigm to attenuate the explosive increase in betel quid use in Taiwan.

The economic impact of clean indoor air laws.

Clean indoor air laws are easily implemented, are well accepted by the public, reduce nonsmoker exposure to secondhand smoke, and contribute to a reduction in overall cigarette consumption. There are currently thousands of clean indoor air laws throughout the Unites States, and the majority of Americans live in areas where smoking is completely prohibited in workplaces, restaurants, or bars. The vast majority of scientific evidence indicates that there is no negative economic impact of clean indoor air policies, with many studies finding that there may be some positive effects on local businesses. This is despite the fact that tobacco industry‐sponsored research has attempted to create fears to the contrary. Further progress in the diffusion of clean indoor air laws will depend on the continued documentation of the economic impact of clean indoor air laws, particularly within the hospitality industry. This article reviews the spread of clean indoor air laws, the effect on public health, and the scientific evidence of the economic impact of implementation of clean indoor air laws.

Explanations of ethnic and gender differences in youth smoking: A multi-site, qualitative investigation

Two of the most powerful predictors of adolescent smoking are ethnicity and gender, but little research has focused on understanding how these factors play a role in adolescent smoking. This paper reports results from a qualitative, multi-site investigation of explanations for ethnic and gender differences in cigarette smoking with five ethnic groups: whites, African-Americans, Hispanics, Native Americans, and Asian-American/Pacific Islanders. Across 11 states, we conducted 178 focus groups with a total of 1175 adolescents. The groups explored such major research themes as reasons for smoking and not smoking; images of smoking and smokers; messages youth receive about smoking and not smoking; and the social context of smoking. We synthesized data from the focus groups through multiple cross-site collaborations and discussions, with an emphasis on identifying consistent themes across a majority of groups and sites. Striking differences emerged across ethnic and gender sub-groups in reasons for not smoking. African-American females in particular viewed not smoking as a positive identity marker. Asian-American/Pacific Islander females similarly reported strong mandates not to smoke. Youths perceptions of family messages about smoking also varied by ethnicity and gender, with African-American, Hispanic, and Asian-American/Pacific Islander youth consistently reporting strong, clear anti-smoking messages from family. These findings, notable in their consistency across geographic regions, may shed light on the discrepant prevalence of smoking across ethnic and gender groups.

The Diffusion and Impact of Clean Indoor Air Laws

Over the past quarter century, primarily as a result of scientific discovery, citizen advocacy, and legislative action, comprehensive clean indoor air laws have spread rapidly throughout the world. Laws that establish completely smoke-free indoor environments have many relative advantages including being low cost, safe, effective, and easy to implement. The diffusion of these laws has been associated with a dramatic and rapid reduction in population levels of serum cotinine among nonsmokers and has also contributed to a reduction in overall cigarette consumption among smokers, with no adverse economic impact, except to the tobacco industry. Currently, nearly half of the U.S. population lives in jurisdictions with some combination of completely smoke-free workplaces, restaurants, or bars. The diffusion of clean indoor air laws is spreading rapidly throughout the world, stimulated by the first global health treaty, the Framework Convention on Tobacco Control.

A Review of the Health Impact of Smoking Control at the Workplace

Purpose. To summarize and provide a critical review of worksite health promotion program evaluations published between 1968 and 1994 that addressed the health impact of worksite smoking cessation programs and smoking policies. Methods. A comprehensive literature search conducted under the auspices of the Centers for Disease Control and Prevention identified 53 smoking cessation program evaluation reports, of which 41 covered worksite single-topic cessation programs. Nine additional reports were located through manual search of citations from published reports and reviews. These 50 reports covered 52 original data-based studies of cessation programs. The search produced 19 reports for tobacco policy evaluations, of which 12 addressed health impact. An additional 17 reports were located by the authors. These 29 reports covered 29 studies of policy impact. Summary of Important Findings. Smoking cessation group programs were found to be more effective than minimal treatment programs, although less intensive treatment, when combined with high participation rates, can influence the total population. Tobacco policies were found to reduce cigarette consumption at work and worksite environmental tobacco smoke (ETS) exposure. Conclusions. The literature is rated suggestive for group and incentive interventions; indicative for minimal interventions, competitions, and medical interventions; and acceptable for the testing of incremental effects. Because of the lack of experimental control, the smoking policy literature is rated as weak, although there is strong consistency in results for reduced cigarette consumption and decreased exposure to ETS at work.

Environmental and Policy Interventions to Control Tobacco Use and Prevent Cardiovascular Disease

Despite its declining prevalence during the past few decades, tobacco use remains one of the most significant public health issues of the 1990s. Environmental and policy interventions are among the most cost-effective approaches to control tobacco use and prevent cardiovascular diseases. In this article, the authors review and offer to state and local health departments and other public health partners a summary of recommended policy and environmental interventions that have either reduced or show potential to reduce tobacco use. Priority recommendations include clean indoor air policies, restrictions on tobacco advertising and promotion, policies limiting youth access to tobacco, comprehensive school health programs, and excise taxes and other economic incentives. Many of these recommendations should be integrated with other health promotion interventions to also improve nutrition and physical activity. The authors also highlight several successful interventions and strategies used to establish policies at the state and local levels.
