Results of global youth tobacco surveys in public schools in Bogotá, Colombia.

BACKGROUND: The purpose of this paper is to use data from the Global Youth Tobacco Survey (GYTS) conducted in Bogotá, Colombia, in 2001 and 2007 to examine changes in tobacco use among youth 13-15 years of age. The current tobacco control effort in Bogotá will be accessed relative to Colombia ratifying the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) in 2008. METHODS: GYTS was implemented in public schools in Bogotá, Colombia, by the Colombian National Cancer Institute. Data were collected from students in classrooms using self-administered procedures. RESULTS: Between 2001 and 2007, ever having smoked cigarettes decreased along with exposure to secondhand smoke (SHS) at home, having an object with a tobacco logo on it, and having been offered free cigarettes by a tobacco company representative. Prevalence of current cigarette smoking did not change from 2001 to 2007 (32.9% and 29.9%). Exposure to pro-tobacco advertising increased, reaching 71.4%, and 73.4% respectively, in 2007. Having been taught about the harmful effects of tobacco use did not change over time. CONCLUSIONS: The government of Colombia ratified the WHO FCTC in 2008. However, Colombia has one of the highest levels of cigarette smoking among 13-15 year olds in the Region of the Americas. The tobacco control effort in Colombia has much work to do, including recognition that the levels of smoking among adolescents are already as high as those of adults. Future declines in tobacco use among adolescents in Bogotá will likely depend on development of a comprehensive tobacco control program.

Prevalence of smoking and other smoking related behaviors reported by the Global Youth Tobacco Survey (GYTS) in four Peruvian cities.

INTRODUCTION: In 2004, Peru ratified the Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) and in 2006 passed Law 28705 for tobacco consumption and exposure reduction. The Global Youth Tobacco Survey (GYTS) provides data on youth tobacco use for development of tobacco control programs. Findings from the GYTS conducted in four main cities in Peru in 2000 and 2003 are reported in this paper and can be used to monitor provisions of the WHO FCTC. METHODS: The GYTS is a school-based survey that uses a standardized methodology for sampling, questionnaire construction, field procedures, and data management. In total, 5,332 and 7,824 students aged 13 to 15 years participated in the 2000 and 2003 surveys conducted in Huancayo, Lima, Tarapoto and Trujillo. RESULTS: In both years, Lima had the highest lifetime (54.6% and 59.6%) and current use of tobacco (18.6% and 19.2%) of the four cities. According to gender, boys smoked more than girls and less than 20% of students initiated smoking before the age of 10. Among smokers, more than 60% bought their cigarettes in a store with no restriction for their age, and approximately 12% had ever been offered "free cigarettes". Around 90% of students were in favor of banning smoking in public places. Changes between 2000 and 2003 included an increase in the percentage of smokers who wanted to have a cigarette first thing in the morning in Tarapoto (from 0% to 1.2%) and a decrease in exposure to tobacco at home in Huancayo (from 23.7% to 17.8%) and Trujillo (from 27.8% to 19.8%) CONCLUSION: While few changes in tobacco use among youth have been observed in the GYTS in Peru, the data in this report can be used as baseline measures for future evaluation efforts. At this time, tobacco control efforts in Peru need to focus on enhancing Law 28705 to include enforcement of existing provisions and inclusion of new laws and regulations. Most of these provisions are required of all countries, such as Peru, that have ratified the WHO FCTC.

Linking Global Youth Tobacco Survey (GYTS) data to the WHO Framework Convention on Tobacco Control (FCTC): the case for Mexico.

BACKGROUND: The adoption of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) in 2004 marked a critical achievement in efforts to stem the tobacco epidemic in Mexico. The Global Youth Tobacco Survey (GYTS) findings are useful for evaluating achievement of FCTC articles and designing tobacco control programs. OBJECTIVE: To use data from the GYTS conducted in 21 Mexican cities between 2000 and 2005 to monitor Articles in the WHO FCTC. METHODS: The GYTS uses a two-stage cluster sample survey design that produces representative samples of students aged 13-15 years enrolled in public, private and technical schools. The survey was undertaken at 542 schools in 21 cities. The GYTS surveyed 43,950 students during 2000-2005. RESULTS: The current smoking rate ranged from 10.7% to 29.4%. Among never smokers, susceptibility to initiate smoking ranged from 20.2% to 34.4%. Among current smokers, the percentage who bought their cigarettes in a store was above 40% in 6 cities, but significantly declined over five years in the only city with two assessments (Monterrey). Exposure to secondhand smoke in public places was greater than 50% in 15 of the 21 cities. Over 80% of students in all 21 cities reported that they saw of advertisements for cigarettes on billboards. CONCLUSION: Using determinants measured by GYTS in Mexico, the government can monitor the impact of enforcing various provisions of the National Health Law and the progress made in achieving the goals of the WHO FCTC and the Regional strategy. When these goals are met, tobacco consumption and exposure in Mexico will have declined substantially.

Linking Global Youth Tobacco Survey (GYTS) data to the WHO Framework Convention on Tobacco Control (FCTC): the case for Brazil.

OBJECTIVE: The Global Youth Tobacco Survey (GYTS) in Brazil was developed to provide data on youth tobacco use to the National Tobacco Control Program. METHOD: The GYTS uses a standardized methodology for constructing sampling frames, selecting schools and classes, preparing questionnaires, carrying out field procedures, and processing data. The GYTS questionnaire is self-administered and includes questions about: initiation; prevalence; susceptibility; knowledge and attitudes; environmental tobacco smoke; cessation; media and advertising. SUDDAN and Epi-Info Software were used for analysis. Weighted analysis was used in order to obtain percentages and 95% confidence intervals. RESULTS: Twenty-three studies were carried out between 2002 and 2005 in Brazilian capitals: 2002 (9); 2003 (4); 2004 (2) and 2005 (9). The total number of students was 22832. The prevalence rate among the cities varied from 6.2% (João Pessoa, 2002) to 17.7% (Porto Alegre, 2002). CONCLUSION: The tobacco use prevalence rates in 18 Brazilian cities show significant heterogeneity among the macro regions. Data in this report can be used to evaluate the efforts already done and also as baseline for evaluation of new steps for tobacco control in Brazil regarding the goals of the WHO FCTC.
