Tobacco endgame in the WHO European Region: Feasibility in light of current tobacco control status. Tob Induc Dis 2023; 21:151. [PMID: 38026503 PMCID: PMC10647070 DOI: 10.18332/tid/174360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/20/2023] [Accepted: 10/23/2023] [Indexed: 12/01/2023] Open
Abstract
INTRODUCTION To assess the feasibility of developing World Health Organization (WHO) European Region countries' goals and measures in line with tobacco endgame objectives, information on the current tobacco control context and capacity is needed. The aim of this study was to assess the implementation of the Framework Convention on Tobacco Control (WHO FCTC) and MPOWER measures in the region. METHODS In this cross-sectional study we used data from the WHO FCTC implementation reports and MPOWER from 2020 in 53 WHO European Region countries. Six domains (i.e. capacity, taxation and price policies, other national key regulations, public awareness raising and communication, tobacco use cessation, and monitoring) were formed. Subsequently, available indicators under these domains were scored and the level of implementation was computed for each country. Mann-Whitney tests were carried out to compare the scores between the group of countries with and without official endgame goals. RESULTS Overall, implementation of the WHO FCTC with the selected indicators at the country level ranged from 28% to 86%, and of MPOWER from 31% to 96%. Full implementation was achieved by 28% of WHO FCTC Parties in the region in taxation and price policies, 12% in public awareness raising and communication, and 42% in monitoring. In capacity, tobacco use cessation and other national key regulations, none of the Parties in the region reached full implementation. Overall median WHO FCTC scores were significantly higher in countries with official endgame goals than in those without (p<0.001). CONCLUSIONS There is unequal implementation of both WHO FCTC and MPOWER measures among WHO European Region countries. MPOWER and WHO FCTC provide all the measures for the necessary first steps, followed by innovative measures, to accomplish tobacco endgame goals.

Transitions in smoking status in nursing students: A prospective longitudinal study. J Adv Nurs 2023; 79:3456-3472. [PMID: 36978253 DOI: 10.1111/jan.15665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 02/09/2023] [Accepted: 03/16/2023] [Indexed: 03/30/2023]
Abstract
AIM To describe transitions in smoking status and their determining factors among nursing students between baseline (2015-2016) and follow-up (2018-2019). DESIGN Observational prospective longitudinal study of 4381 nursing students in Catalonia (Spain). METHODS We examined transitions in smoking status from: (i) current smokers to recent quitters, (ii) never smokers to new smokers and (iii) former smokers to quitters who relapsed. We fitted logistic regression models to assess the predictors of quitting smoking. RESULTS The proportion of current smokers decreased from 29.7% at baseline to 23.6% at follow-up, with a cumulative incidence rate of quitting of 28.3% during follow-up. Nondaily smokers were more likely to quit than daily smokers. Of those who were never smokers at baseline, 4.6% were smokers at follow-up, and 23.2% of former smokers at baseline had relapsed at follow-up. CONCLUSIONS Nondaily smokers were more likely to have quit smoking at follow-up among this cohort of nursing students. The early implementation of a comprehensive tobacco control program that includes tobacco-free campus policies, tobacco prevention interventions and cessation support during college years may decrease tobacco use among nursing students. IMPACT Nursing students' tobacco use is concerning, as they are the future workforce of nurses who have a key role in tobacco product use prevention and cessation. During college years, nursing students have a greater likelihood of experimenting with several smoking status changes as well as to consolidate smoking behaviors. This is the first longitudinal study to highlight the factors associated with quitting smoking among a cohort of Spanish nursing students. Being a nondaily smoker at baseline predicted quitting at follow-up. Our findings support the early implementation of a comprehensive tobacco control program that includes tobacco-free campus policies, tobacco prevention interventions and tobacco cessation support during college years to decrease tobacco product use prevalence among nursing students. REPORTING METHOD We have adhered to STROBE guidelines. No Patient or Public Contribution. This observational study has not been registered.

Changes in tobacco imagery and smokers' depiction in Spanish top-grossing films before and after the implementation of a comprehensive tobacco control policy in Spain. Tob Induc Dis 2023; 21:66. [PMID: 37215193 PMCID: PMC10198122 DOI: 10.18332/tid/162700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 03/22/2023] [Accepted: 03/27/2023] [Indexed: 05/24/2023] Open
Abstract
INTRODUCTION As more restrictions on tobacco marketing communication are implemented, tobacco marketing has persisted through smoking in films. Our aims were to assess changes in tobacco imagery exposure in Spanish top-grossing films before and after the banning of tobacco advertising in Spain, and to determine whether the depiction of smoking characters has changed over the years. METHODS A repeated cross-sectional study measured the tobacco content in the 10 Spanish top-grossing films in 2005, 2010 and 2015 (n=30) before and after a complete tobacco advertising ban. We conducted a descriptive and regression analysis of changes in tobacco impressions by year. RESULTS The 30 films contained 1378 tobacco occurrences (90.2% positive for tobacco) with a median length of eight seconds onscreen. Total tobacco occurrences deemed positive for tobacco interests significantly increased in 2010 and 2015 compared to 2005. However, we observed decreased odds of tobacco brands appearances (OR=0.25; p<0.001) in 2010 and of implied tobacco use (OR=0.44; p=0.002), and tobacco brands appearances (OR=0.36; p<0.001) in 2015 compared to 2005. There was a change of pattern in the type of role smokers played from a leading role to a supporting one (p<0.001). The population reach of positive for tobacco occurrence in Spanish top-grossing films decreased from 15.9 (95% CI: 15.86-15.86) per 1000 spectators in 2005 to 0.8 (95% CI: 0.82-0.82) in 2015. CONCLUSIONS The implementation of a ban on complete tobacco product advertising was followed by a decrease in tobacco incidents across top-grossing Spanish films. Yet, exposure to smoking in films is still unacceptably high.

Exposure of 4-year to 24-year olds to tobacco imagery on prime-time Chilean television. Tob Control 2023; 32:323-329. [PMID: 34607886 PMCID: PMC10176395 DOI: 10.1136/tobaccocontrol-2021-056735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 08/27/2021] [Indexed: 11/03/2022]
Abstract
INTRODUCTION The extent of the population's exposure to tobacco imagery across all genres of regular TV programming and the contribution of each of these genres is unknown, except for UK broadcast channels. The objective of this study is to estimate the exposure of young people to tobacco imagery on Chilean prime-time television and the programme source contributing to such exposure. METHODS Programmes aired during 3 weeks in 2019 from the 15 highest audience channels in Chile were content-analysed for the occurrence of tobacco categorised as actual use, implied use, tobacco paraphernalia, tobacco brand appearances and whether they violated Chilean smoke-free law for each 1 min interval (92 639). The exposure of young people to tobacco content was estimated using media viewership figures. RESULTS Young people received 29, 11 and 4 million tobacco impressions of any type, explicit use and smoke-free violation, respectively, at a rate of 21.8, 8.0 and 2.1 thousand impressions per hour of TV viewing. The main sources of exposure to tobacco impressions were feature films and animated productions, which were almost entirely non-Chilean. Finally, young people were exposed to tobacco brand impressions primarily through films, effectively circumventing the advertising ban in Chile. DISCUSSION Television programming is a source of significant youth exposure to tobacco imagery, including branding impressions. To conform to the WHO FCTC, Chile should prohibit tobacco branding in any TV programme and require strong anti-tobacco advertisements prior to any TV programme portraying tobacco.

Exposure to tobacco impressions during prime-time TV
among Chilean minors by sex and socioeconomic status. Tob Induc Dis 2022; 20:96. [PMID: 36407939 PMCID: PMC9644231 DOI: 10.18332/tid/155264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 10/09/2022] [Accepted: 10/12/2022] [Indexed: 11/11/2022] Open
Abstract
INTRODUCTION We tested if tobacco impressions were delivered differentially to prime-time TV watching minors by sex and socioeconomic status. METHODS Programs aired during prime-time for three random weeks in 2019 from the 15 highest audience channels in Chile were content-analyzed for the occurrence of tobacco for each one-minute interval of 92639 recorded. Such occurrences were categorized as actual use and whether they violated Chilean smoke-free law or tobacco brand appearances. We estimated the number of persons per hour (p/h) exposed to tobacco impressions for the 4 to 17 years age group by sex and socioeconomic status (SES). RESULTS Minors spent over a billion p/h watching TV during the observation period. Minors were exposed to tobacco explicit use, branding and smoke-free violation impressions for 9.7 million, 1.2 million, and 1.0 million p/h, respectively. The odds ratios (OR) of exposure to total tobacco impressions were always greater among boys with higher SES compared to boys with low SES. However, they were greater among girls of low SES compared to those of high SES for all types of impressions. The OR of exposure to tobacco branding was higher among girls of any SES compared to boys of any SES. CONCLUSIONS Minors need protection from tobacco imagery on television, particularly girls of low SES. To that end, new legislation should implement all measures to counter depictions of tobacco in entertainment media, as recommended in the WHO FCTC Article 13 guidelines. This should require strong anti-tobacco advertisements before any TV program portraying tobacco targeting minor audiences, particularly girls of low SES. Given that Chile has one of the highest prevalences in the world of current cigarette smoking among young females, the potential contribution of tobacco impressions on TV to smoking differentials across female socioeconomic groups should be further studied.

Abstract
OBJECTIVE To test whether electronic cigarettes use among secondary school students in Spain is associated with initiating nicotine use. METHOD Secondary analysis of the ESTUDES 2019 survey, a cross-sectional study conducted on a representative sample of students aged 14-18 years and selected students who had never smoked (n=16,705). We computed the prevalence and estimated the factors associated with current electronic cigarettes use (at least once in the month before the interview), with and without nicotine. RESULTS The prevalence of current electronic cigarettes use among students who have never smoked is 2.5% (95% confidence interval [95%CI]: 2.2-2.9). 0.1% (95%CI: 0.08-0.2) declared using liquids with nicotine at least sometimes and 2.4% (95%CI: 2.1-2.8) using liquids always without nicotine. Being male and under 17 years of age, reporting binge drinking behavior, and having regular friends who use cannabis, increases the probability of current use of electronic cigarettes. The latter two variables seem to act as contextual variables associated with electronic cigarettes use. CONCLUSIONS The percentage of Spanish never smoker students who currently use electronic cigarettes is lower than in neighboring countries, except for the United Kingdom. Only one in every 1000 Spanish students between 14 and 18 years old who have never smoked initiates the current use of nicotine with an electronic cigarette. However, we must monitor the evolution of this indicator.

Abstract
BACKGROUND Monitoring tobacco control policy implementation is one of the keys for tobacco consumption reduction in Latin America (LA). This study reports on the adaptation of the Tobacco Control Scale (TCS) for use in LA countries and the level of tobacco control policy implementation in this region according to the scale. METHODS Ecological cross-sectional survey. The questionnaire to measure tobacco control policies was a translated (into Spanish and Portuguese) and adapted version of the last TCS as used in Europe. The resulting TCS-LA maintains the same structure as the original TCS, with eight policy domains and 100 points (pts) as maximum score; however, four policy domains were adapted because the exact same rationale could not be applied. At least two non-governmental tobacco control experts were contacted per country to answer the TCS-LA. RESULTS Informants from 17 out of 18 countries completed the questionnaire. Using the TCS-LA, Panama (70 pts), Uruguay (68 pts) and Ecuador (61 pts) exhibited the strongest tobacco control policies, while Guatemala (32 pts), Bolivia (30 pts) and Dominican Republic (29 pts) have implemented a lower number of tobacco control policies. Eight countries reached 50% of the TCS-LA total possible score, indicating a relatively good implementation level of tobacco control policies. CONCLUSIONS Panama, Uruguay and Ecuador are the tobacco control policy leaders in LA; however, tobacco control in the region has room for improvement since nine countries have a total score under 50 pts. The TCS is a feasible and adaptable tool to monitor tobacco control in other WHO regions beyond Europe.

Removal efficiency for emerging contaminants in a WWTP from Madrid (Spain) after secondary and tertiary treatment and environmental impact on the Manzanares River. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 812:152567.

Abstract
The effluents from wastewater treatment plants (WWTPs) can be an important contamination source for receiving waters. In this work, a comprehensive study on the impact of a WWTP from Madrid on the aquatic environment has been performed, including a wide number of pharmaceuticals and pesticides, among them those included in the European Watch List. 24-h composite samples of influent (IWW) and effluent wastewater after secondary (EWW2) and after secondary + tertiary treatment (EWW3) were monitored along two campaigns. Average weekly concentrations in IWW and EWW2 and EWW3 allowed estimating the removal efficiency of the WWTP for pharmaceutical active substances (PhACs). In addition, the impact of EWW3 on the water quality of the Manzanares River was assessed, in terms of PhAC and pesticide concentrations, through analysis of the river water collected upstream and downstream of the discharge point. After a preliminary risk assessment, a detailed evaluation of the impact on the aquatic environment, including a toxicological study and screening of pharmaceutical metabolites, was made for the seven most relevant PhACs: sulfamethoxazole, azithromycin and clarithromycin (antibiotics), metoprolol (antihypertensive), diclofenac (anti-inflammatory/analgesic), irbesartan (antihypertensive), and the antidepressant venlafaxine. Among selected PhACs, irbesartan, clarithromycin and venlafaxine presented moderate or high risk in the river water downstream of the discharge. Albeit no acute toxicity was detected, more detailed studies should be carried out for these substances, including additional toxicological studies, to set up potential sublethal and chronic effects on aquatic organisms.

Abstract
As cigarette sales decline, the tobacco industry has turned to the sale of heated tobacco products (HTP), which are on the rise. We are concerned with reports erroneously indicating that heated tobacco is associated with a lower risk of cancer and other diseases than conventional cigarettes, citing as a source the Food and Drug Administration (FDA) of the United States. The FDA has indeed authorized the sale of an HTP, but denies that this approval is an endorsement of the product or that it is safe. Philip Morris asked the FDA to approve this product as a "modified risk" tobacco product. However, the Agency denied that the risk to users' health was less than conventional cigarettes, despite emitting less amount of some toxicants. Spain and the European Union should end the regulatory privileges that HTPs have until now. We identified at least five aspects to improve: 1) compliance with the prohibition of HTPs use where smoking is prohibited; 2) control of the prohibition of advertising, promotion, and sponsorship of HTPs; 3) that HTPs carry the same type of labeling as cigarettes; 4) limit that HTPs have characteristic aromas; and 5) treat HTPs fiscally at the same level as cigarettes.

Abstract
Prevalence of smoking and e-cigarette use among teenagers in Poland is high. Polish law bans most advertising and promotion for cigarettes, e-cigarettes, and heated tobacco products (HTPs). This study investigates marketing for these products at points of sale (POS) near secondary schools in Warsaw, Poland, noting if the advertising and promotion were allowed under current Polish laws. All POS within 250 m radii of five selected secondary schools in each of three Warsaw districts were assessed for tobacco and e-cigarette direct advertising, inside and outside; offers of gifts or promotional discounts; tobacco merchandising, and tobacco displays. Of the 112 POS surveyed, 83% exposed customers to some form of advertising or promotion of cigarettes, e-cigarettes, or HTPs; in 76%, advertising or promotion that violated Polish law was present. More than 80% of POS surveyed displayed tobacco products; in 19%, these products were displayed near products of interest to minors. POS density observed here was 30.3 per km2, higher than in other European cities. In Poland, a high proportion of POS near schools violates the law banning the advertisement and promotion of tobacco and nicotine consumer products through a dense tobacco retailer network.

Abstract
Noncommunicable diseases (NCDs), including cancer, are responsible for almost 70% of all deaths worldwide. Tobacco use is a risk factor common to most NCDs. This article discusses tobacco control policies and highlights major achievements and open challenges to reduce smoking prevalence and attributable morbidity and mortality in the 21st century. The introduction of the WHO Framework Convention on Tobacco Control in 2005 has been a key achievement in the field and has already facilitated a drop in both smoking prevalence and exposure to secondhand smoke. Indicatively, the size of the worldwide population benefiting from at least one cost‐effective tobacco control policy has quadrupled since 2007. In addition, plain cigarette packaging has been successfully introduced as a tobacco control policy, surmounting efforts of the tobacco industry to challenge this based on trade and investment law. Nevertheless, tobacco control still faces major challenges. Smoking prevalence needs to be further reduced in a rather expedited manner. Smoke‐free environments should be extended, and the use of plain tobacco packaging with large pictorial health warnings for all tobacco products should be further promoted in some parts of the world. Some of these measures will require prompt determination and diligence. For example, bold political decisions are needed to significantly increase real prices of tobacco products through excise taxes, ban added ingredients that are currently used to increase the attractiveness of tobacco products and ban the tobacco industry's corporate social responsibility initiatives. Finally, the debate on harm reduction strategies for tobacco control still needs to be resolved.

The Tobacco Control Scale as a research tool to measure country-level tobacco control policy implementation. Tob Induc Dis 2020; 18:91.

Abstract
INTRODUCTION The Tobacco Control Scale (TCS) was designed for advocacy purposes but has also been used as a research tool. In the present study, we characterized TCS use, its limitations and strengths, and critically assessed its use as a research instrument. METHODS We conducted an extensive search of the biomedical databases PubMed and Web of Science for the keyword ‘tobacco control scale’ in all fields. The search was limited to studies published in the period March 2006 to December 2019. Out of 69 hits, 32 studies met the inclusion criteria. Two reviewers independently extracted information from each publication regarding their general characteristics, publication and research aspects, and the characteristics of the use of the TCS. RESULTS We found that researchers have used the TCS as a tool to monitor tobacco control policies mainly in cross-sectional observational studies with ecological and multilevel designs directed to advocacy and the promotion of further research. Different outcomes, such as smoking prevalence and quit ratios, have been associated with tobacco control policy scores. The main reported limitations of the TCS were a low variance across countries and a failure to express enforcement and to incorporate the most recent legislation. CONCLUSIONS The TCS has been commonly used to assess differences in outcomes according to tobacco control policies. However, there are still areas for improvement in its use in research regarding the lack of comparability of TCS scores across time. The lessons that have been learned should be used to adapt and expand the TCS overseas.

[PMID: 32765201 PMCID: PMC7398597 DOI: 10.18332/tid/125075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 06/13/2020] [Accepted: 07/08/2020] [Indexed: 11/24/2022] Open
Abstract
INTRODUCTION The aim of the study is to assess the national level of compliance with the Chilean smoke-free legislation in the urban public transportation system. METHODS In this cross-sectional observational study, we studied a national representative sample of 475 vehicles obtained through a two-stage cluster sampling design in 2018. First, 57 municipalities were randomly selected, proportionally to the total number of public transportation vehicles. Second, within each municipality, a convenience sample of up to 4 taxis, 4 buses, and 2 metro coaches was observed. We determined the non-compliance level by systematic direct observation of smoking inside the cabin of the vehicle. We estimated the percentage of the visited vehicles where smoking was observed inside the cabin of the vehicle. RESULTS The observation of metros, buses and taxis was completed in 24, 52, and 48, of the 57 sampled municipalities, respectively. Smoking was observed inside of about 2% of buses and 7% of taxis. Smoking was not observed in metro carriages. Overall, smoking was observed in almost 3% of the vehicles studied. A 3% noncompliance could expose a significant number of persons in public transportation to secondhand smoke, given that every 100 inhabitants results in about 84 rides a day of almost one hour duration. There are few comparable studies to put in an international context our results. In 2018, the year in which we collected the data, WHO considered that compliance with the law in public transportation was maximum. Our compliance estimate was lower, however WHO used a different methodology and its scope also included the inter-urban mobility, which we did not. CONCLUSIONS The study highlights the need to improve the enforcement of the smoke-free law in the transportation system in Chile, which presently is almost non-existent.

Compliance with the smoking ban in enclosed, semiopen and open areas of workplaces and public places in Chile. Tob Control 2020; 30:570-573. [PMID: 32703800 DOI: 10.1136/tobaccocontrol-2020-055632] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 04/23/2020] [Accepted: 05/09/2020] [Indexed: 11/03/2022]
Abstract
OBJECTIVE To assess the national level of compliance with the Chilean comprehensive smoke-free legislation by observing healthcare facilities, education centres, government offices, hospitality venues and private workplaces, by type of area within workplaces and public places: enclosed, semiopen and open. METHODOLOGY In this cross-sectional observational study, we studied a national representative sample of 3253 venues obtained through a two-stage cluster sampling design. First, 57 municipalities were randomly selected, proportionally to the total number of venues of interest. Second, within each selected municipality, a maximum of 12 venues of each sector was selected systematically from a list of existing sites. We determined the non-compliance level by estimating the percentage of the visited venues where smoking was observed or suspected in banned areas of the premises. RESULTS Smoking or suspicion thereof was not observed in any enclosed area of any establishment. However, smoking violations were observed in semiopen areas ranging from less than 0.5% of schools and healthcare centres to around 10% of hospitality venues or 23.0% of higher education centres. Smoking violations were also observed in outdoor areas of 6.7% and 1.6% of the health centres and schools, respectively. DISCUSSION The stark contrast in compliance with the smoking ban between the enclosed areas and the semiopen areas may be a consequence of the complex definition of semiopen areas in the regulations. The study also reflects the need to improve the overall enforcement of the smoke-free law, particularly in universities and hospitality venues.

Night entertainment venues comply poorly with the smoke-free law in Chile. GACETA SANITARIA 2020; 35:402-404. [PMID: 32682515 DOI: 10.1016/j.gaceta.2020.04.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 03/23/2020] [Accepted: 04/06/2020] [Indexed: 11/26/2022]
Abstract
The initial high level of compliance with the Chilean comprehensive national smoke-free law in 2013 is fading, particularly in the hospitality sector. This paper draws attention to how using a simple and low-cost surveillance inquiry may help focus on the use of scarce inspection resources to improve compliance with the law in the hospitality sector. We conducted a cross-sectional assessment of second-hand smoke exposure in night entertainment venues in Santiago, Chile, by measuring particulate matter of less than 2.5μm (PM2.5). Smoking where prohibited by law was observed in 36% of the venues visited. Venues where smoking was spotted at the time of the observation had a median PM2.5 concentration 13 times higher than background concentration on the street. The study shows that a targeted approach for inspection to find pockets of venues with suboptimal compliance is feasible and affordable.

Secondhand exposure to aerosol from electronic cigarettes: pilot study of assessment of tobacco-specific nitrosamine (NNAL) in urine. GACETA SANITARIA 2018; 33:575-578. [PMID: 30377020 DOI: 10.1016/j.gaceta.2018.07.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Revised: 07/02/2018] [Accepted: 07/06/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVE To assess the levels of a tobacco-specific nitrosamine (NNAL) in non-smokers passively exposed to the second-hand aerosol (SHA) emitted from users of electronic cigarettes (e-cigarettes). METHOD We conducted an observational study involving 55 non-smoking volunteers divided into three groups: 25 living at home with conventional smokers, 6 living with e-cigarette users, and 24 in control homes (smoke-free homes). We obtained urine samples from all volunteers to determine NNAL. RESULTS We detected NNAL in the urine of volunteers exposed to e-cigarettes (median:0.55 pg/mL; interquartile range: 0.26-2.94 pg/mL). The percentage of urine samples with quantifiable NNAL differed significantly among the three groups of homes: 29.2%, 66.7% and 76.0%, respectively (p=0.004). CONCLUSIONS We found NNAL nitrosamine in urine samples from people exposed to SHA from e-cigarettes. However, these results could be confirmed with more studies with larger sample sizes.

Abstract
BACKGROUND One in five deaths that occur in Chile can be attributed to smoking whose prevalence remains high, despite interventions aimed at reducing it. AIM To compare the prevalence of smoking and its intensity among young adults born 15 years apart and determine their association with socioeconomic status (SES). MATERIAL AND METHODS Two cohorts of young adults living in the Valparaiso Region of Chile were evaluated in the third decade of life. Cohort 1 was evaluated between 2000 and 2002 (n = 1232) and cohort 2 between 2014 and 2017 (n = 1078). RESULTS In cohort 1, 57.5% (95% Confidence Interval (CI) 54.6-58.7) of the subjects reported smoking, with a median of 3 (Interquartile range (ICR:1-6) cigarettes/day. This percentage fell to 40.2% (CI: 37.5-43.1) with a similar median in cohort 2. Analyzing cohort 2, the odds ratio (OR) for smoking was 2.24 (CI 1.48-3.38) in the medium SES, compared with the medium high SES. The figures for low medium and low SES were 2.72 (CI: 1.85-3.99) and 3.01 (1.85-4.88). Similarly, in this cohort there was a significantly higher risk of being a heavy smoker in lower SES. No associations between smoking or its intensity and SES were observed in cohort 1. CONCLUSIONS Smoking behavior has decreased among young adults evaluated at the same age in two generational cohorts in the third decade of life. In the most recent cohort analyzed, smoking and its intensity increase along with a decrease in SES.

Abstract
OBJECTIVE To describe the prevalence and change in prevalence of electronic nicotine delivery systems (ENDS) use in youth by country and combustible smoking status. METHODS Databases and the grey literature were systematically searched to December 2015. Studies describing the prevalence of ENDS use in the general population aged ≤20 years in a defined geographical region were included. Where multiple estimates were available within countries, prevalence estimates of ENDS use were pooled for each country separately. RESULTS Data from 27 publications (36 surveys) from 13 countries were included. The prevalence of ENDS ever use in 2013-2015 among youth were highest in Poland (62.1%; 95%CI: 59.9-64.2%), and lowest in Italy (5.9%; 95%CI: 3.3-9.2%). Among non-smoking youth, the prevalence of ENDS ever use in 2013-2015 varied, ranging from 4.2% (95%CI: 3.8-4.6%) in the US to 14.0% in New Zealand (95%CI: 12.7-15.4%). The prevalence of ENDS ever use among current tobacco smoking youth was the highest in Canada (71.9%, 95%CI: 70.9-72.8%) and lowest in Italy (29.9%, 95%CI: 18.5-42.5%). Between 2008 and 2015, ENDS ever use among youth increased in Poland, Korea, New Zealand and the US; decreased in Italy and Canada; and remained stable in the UK. CONCLUSIONS There is considerable heterogeneity in ENDS use among youth globally across countries and also between current smokers and non-smokers. Implications for public health: Population-level survey data on ENDS use is needed to inform public health policy and messaging globally.

Correlates of compliance with national comprehensive smoke-free laws. Tob Control 2017; 27:tobaccocontrol-2017-053920. [PMID: 29208739 DOI: 10.1136/tobaccocontrol-2017-053920] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2017] [Revised: 08/31/2017] [Accepted: 10/02/2017] [Indexed: 11/04/2022]
Abstract
OBJECTIVE To explore correlates of high compliance with smoking bans in a cross-sectional data set from the 41 countries with national comprehensive smoke-free laws in 2014 and complete data on compliance and enforcement. METHODS Outcome variable: compliance with a national comprehensive smoke-free law in each country was obtained for 2014 from the WHO global report on the global tobacco epidemic. Explanatory variables: legal enforcement requirements, penalties, infrastructure and strategy were obtained through a separate survey of governments. Also, country socioeconomic and demographic characteristics including the level of corruption control were included. ANALYSIS an initial bivariate analysis determined the significance of each potentially relevant explanatory variable of high compliance. Differences in compliance were tested using the exact logistic regression. RESULTS High compliance with the national comprehensive smoke-free law was associated with the involvement of the local jurisdictions in providing training and/or guidance for inspections (OR=10.3, 95% CI 1.7 to 117.7) and a perception of high corruption control efforts in the country (OR=7.2, 95% CI 1.1 to 85.8). DISCUSSION The results show the importance of the depth of the enforcement infrastructure and effort represented by the degree to which the local government is involved in enforcement. They also show the significance of fighting corruption in the enforcement process, including the attempts of the tobacco industry to undermine the process, to achieve high levels of compliance with the law. The results point out to the need to invest minimal but essential enforcement resources given that national comprehensive smoke-free laws are self-enforcing in many but not all countries and sectors.

Abstract
Sexually transmitted diseases (STDs) are an important public health problem, due to their medical, social and economic repercussions. Therefore, more knowledge is needed about the sexual behaviour that promotes their spread, in order to improve control and prevention strategies. Our aim was to determine the frequency of male condom use associated with sexual behaviour factors, a history of and knowledge about STDs in a sample of the male population in Mexico City. During 1994 a cross-sectional epidemiological study was carried out, using multi-stage sampling with conglomerates, in 1377 men from 15 to 49 years old. The mean age was 34.5 years (SD 7.5 years). Mean age at first sexual relations was 17.7 years (SD 2.8 years). The global proportion of condom use during the last sexual relation was 24.6%; use according to type of female sex partner in the last year was 18.8% with regular partners and 62.5% with occasional partners. The principal predictors of male condom use, identified through statistical modelling, were: younger age (<25 years), middle and high education level (>9 years), middle and high socioeconomic level and type of sexual partners (occasional and regular). This population has risk factors for acquiring and transmitting some STDs, such as occasional sexual partners and a history of STDs. Characteristics which are important in relation to male condom use were identified, such as age (younger than 35), education (complete junior high school or more) and type of sexual partners (occasional and regular).

Abstract
Tobacco use, and in particular cigarette smoking, is the single largest preventable cause of cancer in the European Union (EU). All tobacco products contain a wide range of carcinogens. The main cancer-causing agents in tobacco smoke are polycyclic aromatic hydrocarbons, tobacco-specific N-nitrosamines, aromatic amines, aldehydes, and certain volatile organic compounds. Tobacco consumers are also exposed to nicotine, leading to tobacco addiction in many users. Cigarette smoking causes cancer in multiple organs and is the main cause of lung cancer, responsible for approximately 82% of cases. In 2012, about 313,000 new cases of lung cancer and 268,000 lung cancer deaths were reported in the EU; 28% of adults in the EU smoked tobacco, and the overall prevalence of current use of smokeless tobacco products was almost 2%. Smokeless tobacco products, a heterogeneous category, are also carcinogenic but cause a lower burden of cancer deaths than tobacco smoking. One low-nitrosamine product, snus, is associated with much lower cancer risk than other smokeless tobacco products. Smoking generates second-hand smoke (SHS), an established cause of lung cancer, and inhalation of SHS by non-smokers is still common in indoor workplaces as well as indoor public places, and more so in the homes of smokers. Several interventions have proved effective for stopping smoking; the most effective intervention is the use of a combination of pharmacotherapy and behavioural support. Scientific evidence leads to the following two recommendations for individual action on tobacco in the 4th edition of the European Code Against Cancer: (1) "Do not smoke. Do not use any form of tobacco"; (2) "Make your home smoke-free. Support smoke-free policies in your workplace".

Abstract
BACKGROUND Since 1988, WHO have celebrated and supported World No Tobacco Day (WNTD), linking each year to a different tobacco-related theme. New technologies and creative design have been used by WHO in order to adapt to the current trends and needs providing the public with visually attractive posters and brochures. METHODS A review of World Health Organization (WHO) material on WNTD was made, every year themes and posters were collected and analysed to be presented in a comprehensive way. RESULTS A systematic timeline and an infographic were designed, enclosing the themes of WNTD across the years. The evolution of WNTD themes was commented on with a historical approach. CONCLUSIONS WNTD has evolved adapting to the current scenarios, and is a good example of a global communication campaign on public health awareness and prevention.

Abstract
OBJECTIVE To evaluate the relative contribution of occupational vs. non-occupational secondhand tobacco smoke exposure to overall hair nicotine concentrations in non-smoking bar and restaurant employees. METHOD We recruited 76 non-smoking employees from venues that allowed smoking (n=9), had mixed policies (smoking and non-smoking areas, n=13) or were smoke-free (n=2) between April and August 2008 in Santiago, Chile. Employees used personal air nicotine samplers during working and non-working hours for a 24-h period to assess occupational vs. non-occupational secondhand tobacco smoke exposure and hair nicotine concentrations to assess overall secondhand tobacco smoke exposure. RESULTS Median hair nicotine concentrations were 1.5 ng/mg, interquartile range (IQR) 0.7 to 5.2 ng/mg. Time weighted average personal air nicotine concentrations were higher during working hours (median 9.7, IQR 3.3-25.4 µg/m(3)) compared to non-working hours (1.7, 1.0-3.1 µg/m(3)). Hair nicotine concentration was best predicted by personal air nicotine concentration at working hours. After adjustment, a 2-fold increase in personal air nicotine concentration in working hours was associated with a 42% increase in hair nicotine concentration (95% confidence interval 14-70%). Hair nicotine concentration was not associated with personal air nicotine concentration during non-working hours (non-occupational exposure). CONCLUSIONS Personal air nicotine concentration at working hours was the major determinant of hair nicotine concentrations in non-smoking employees from Santiago, Chile. Secondhand tobacco smoke exposure during working hours is a health hazard for hospitality employees working in venues where smoking is allowed.

Abstract
Background: The World Health Organization (WHO) MPOWER is a technical package of six tobacco control measures that assist countries in meeting their obligations of the WHO Framework Convention Tobacco Control and are proven to reduce tobacco use. The Global Adult Tobacco Survey (GATS) systematically monitors adult tobacco use and tracks key tobacco control indicators. Methods: GATS is a nationally representative household survey of adults aged 15 and older, using a standard and consistent protocol across countries; it includes information on the six WHO MPOWER measures. GATS Phase I was conducted from 2008–2010 in 14 high-burden low- and middle-income countries. We selected one key indicator from each of the six MPOWER measures and compared results across 14 countries. Results: Current tobacco use prevalence rates ranged from 16.1% in Mexico to 43.3% in Bangladesh. We found that the highest rate of exposure to secondhand smoke in the workplace was in China (63.3%). We found the highest ‘smoking quit attempt’ rates in the past 12 months among cigarette smokers in Viet Nam (55.3%) and the lowest rate was in the Russian Federation (32.1%). In five of the 14 countries, more than one-half of current smokers in those 5 countries said they thought of quitting because of health warning labels on cigarette packages. The Philippines (74.3%) and the Russian Federation (68.0%) had the highest percentages of respondents noticing any cigarette advertising, promotion and sponsorship. Manufactured cigarette affordability ranged from 0.6% in Russia to 8.0% in India. Conclusions Monitoring tobacco use and tobacco control policy achievements is crucial to managing and implementing measures to reverse the epidemic. GATS provides internationally-comparable data that systematically monitors and tracks the progress of the other five MPOWER measures.

Abstract
Chlorothalonil is a non-systemic fungicide that is easily degraded in contact with plants and soil or even by the effect of light and pH. A method for the determination of chlorothalonil in courgettes, strawberries, oranges, leeks and tomato by solvent extraction followed by GC-MS/MS with a triple quadrupole analyser was developed. The causes of chlorothalonil degradation during sample treatment were studied and minimised. The final method was based on extraction with acetone in the presence of 0.1 M EDTA sodium salt solution, and clean-up by SPE using OASIS HLB cartridges. Isotope-labelled hexachlorobenzene (HCB-(13)C(6)) was added as an internal standard to the SPE extracts before analysis by GC-MS/MS (EI) (QqQ) analysis in order to correct for instrumental deviations. Quantification was performed by matrix-matched standard calibration using relative responses to the internal standard. Two MS/MS transitions were used for mass spectrometric determination of chlorothalonil to ensure reliable quantification and confirmation. The method was validated using blank samples (for all matrices) spiked at two levels. Recoveries between 77% and 110% and an RSD below 20% were obtained for 0.1 and 0.01 mg kg(-1) spiking levels (n = 5). The validated method was applied to treated and untreated samples collected from an experimental field where a chlorothalonil formulated was applied.

Abstract
BACKGROUND Exposure to second-hand smoke is common in many countries but the magnitude of the problem worldwide is poorly described. We aimed to estimate the worldwide exposure to second-hand smoke and its burden of disease in children and adult non-smokers in 2004. METHODS The burden of disease from second-hand smoke was estimated as deaths and disability-adjusted life-years (DALYs) for children and adult non-smokers. The calculations were based on disease-specific relative risk estimates and area-specific estimates of the proportion of people exposed to second-hand smoke, by comparative risk assessment methods, with data from 192 countries during 2004. FINDINGS Worldwide, 40% of children, 33% of male non-smokers, and 35% of female non-smokers were exposed to second-hand smoke in 2004. This exposure was estimated to have caused 379,000 deaths from ischaemic heart disease, 165,000 from lower respiratory infections, 36,900 from asthma, and 21,400 from lung cancer. 603,000 deaths were attributable to second-hand smoke in 2004, which was about 1·0% of worldwide mortality. 47% of deaths from second-hand smoke occurred in women, 28% in children, and 26% in men. DALYs lost because of exposure to second-hand smoke amounted to 10·9 million, which was about 0·7% of total worldwide burden of diseases in DALYs in 2004. 61% of DALYs were in children. The largest disease burdens were from lower respiratory infections in children younger than 5 years (5,939,000), ischaemic heart disease in adults (2,836,000), and asthma in adults (1,246,000) and children (651,000). INTERPRETATION These estimates of worldwide burden of disease attributable to second-hand smoke suggest that substantial health gains could be made by extending effective public health and clinical interventions to reduce passive smoking worldwide.

Abstract
Objective To compare air nicotine concentrations according to the smoking policy selected by bars/restaurants in Santiago, Chile before and after the enactment of partial smoking ban legislation in 2007 (establishments could be smoke free, have segregated (mixed) smoking and non-smoking areas, or allow smoking in all areas). Methods The study measured air nicotine concentrations over 7 days to characterise secondhand smoke exposure in 30 bars/restaurants in 2008. Owner/manager interviews and physical inspections were conducted. Results Median IQR air nicotine concentrations measured in all venues were 4.38 (0.61–13.62) μg/m3. Air nicotine concentrations were higher in bars (median 7.22, IQR 2.48–15.64 μg/m3) compared to restaurants (1.12, 0.15–9.22 μg/m3). By smoking status, nicotine concentrations were higher in smoking venues (13.46, 5.31–16.87 μg/m3), followed by smoking areas in mixed venues (9.22, 5.09–14.90 μg/m3) and non-smoking areas in mixed venues (0.99, 0.19–1.27 μg/m3). Air nicotine concentrations were markedly lower in smoke-free venues (0.12, 0.11–0.46 μg/m3). After adjustment for differences in volume and ventilation, air nicotine concentrations were 3.2, 35.5 and 56.2 times higher in non-smoking areas in mixed venues, smoking areas in mixed venues and smoking venues, respectively, compared to smoke-free venues. Conclusions Exposure to secondhand smoke remains high in bars and restaurants in Santiago, Chile. These findings demonstrate that the partial smoking ban legislation enacted in Chile in 2007 provides no protection to employees working in those venues. Enacting a comprehensive smoke-free legislation which protects all people from exposure to secondhand smoke in all public places and workplaces is urgently needed.

Abstract
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. Prev Med 2008; 47 Suppl 1:S20-6. [PMID: 18406456 DOI: 10.1016/j.ypmed.2008.02.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2007] [Accepted: 02/11/2008] [Indexed: 12/26/2022]
Abstract
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. Prev Med 2008; 47 Suppl 1:S4-10. [PMID: 18206221 DOI: 10.1016/j.ypmed.2007.11.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2007] [Revised: 10/03/2007] [Accepted: 11/25/2007] [Indexed: 11/26/2022]
Abstract
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.

Abstract
BACKGROUND Brief intervention by a health professional can substantially increase smoking cessation rates among patients. However, few studies have collected information on tobacco use and training to provide cessation counselling among health professional students. OBJECTIVE To examine tobacco use prevalence and tobacco cessation training among students pursuing advanced degrees in health professions. METHODS The Global Health Professions Student Survey (GHPSS) has been conducted among third-year students attending dental, medical, nursing and pharmacy schools. The GHPSS was conducted in schools during regular lectures and class sessions. GHPSS follows an anonymous, self-administered format for data collection. RESULTS The GHPSS was completed by at least one of the four target disciplines in 31 countries between 2005 and 2007 for a total of 80 survey sites. In 47 of the 80 sites, over 20% of the students currently smoked cigarettes; and in 29 of 77 sites, over 10% of the students currently used other tobacco products. GHPSS data showed that the majority of health professional students recognised that they are role models in society, believed that they should receive training on counselling patients to quit using tobacco, but in 73 of 80 sites less than 40% of the students reported they received such training. CONCLUSIONS Health professional schools, public health organisations and education officials should discourage tobacco use among health professionals and work together to design and implement programmes that train all health professionals in effective cessation counselling techniques. If the goal of the tobacco control community is to reduce substantially the use of tobacco products, then resources should be invested in improving the quality of education of health professionals with respect to tobacco control.

Global youth tobacco surveillance, 2000-2007. MORBIDITY AND MORTALITY WEEKLY REPORT. SURVEILLANCE SUMMARIES (WASHINGTON, D.C. : 2002) 2008; 57:1-28.

Abstract
PROBLEM Tobacco use is a major contributor to deaths from chronic diseases. The findings from the Global Youth Tobacco Survey (GYTS) suggest that the estimate of a doubling of deaths from smoking (from 5 million per year to approximately 10 million per year by 2020) might be an underestimate because of the increase in smoking among young girls compared with adult females, the high susceptibility of smoking among never smokers, high levels of exposure to secondhand smoke, and protobacco indirect advertising. REPORTING PERIOD COVERED This report includes GYTS data collected during 2000-2007 from 140 World Health Organization (WHO) member states, six territories (American Samoa, British Virgin Islands, Guam, Montserrat, Puerto Rico, and the U.S. Virgin Islands), two geographic regions (Gaza Strip and West Bank), one United Nations administered province (Kosovo), one special administrative region (Macau), and one Commonwealth (Northern Mariana Islands). For countries that have repeated GYTS, only the most recent data are included. For countries with multiple survey sites, only data from the capital or largest city are presented. DESCRIPTION OF SYSTEM GYTS is a school-based survey of a defined geographic site that can be a country, a province, a city, or any other geographic entity. GYTS uses a standardized methodology for constructing sampling frames, selecting schools and classes, preparing questionnaires, conducting field procedures, and processing data. GYTS standard sampling methodology uses a two-stage cluster sample design that produces samples of students in grades associated with students aged 13-15 years. Each sampling frame includes all schools (usually public and private) in a geographically defined area containing any of the identified grades. In the first stage, the probability of schools being selected is proportional to the number of students enrolled in the specified grades. In the second sampling stage, classes within the selected schools are selected randomly. All students in selected classes attending school the day the survey is administered are eligible to participate. Student participation is voluntary and anonymous using self-administered data collection procedures. The GYTS sample design produces independent, cross-sectional estimates that are representative of each site. RESULTS The findings in this report indicate that the level of cigarette smoking between boys and girls is similar in many sites; the prevalence of cigarette smoking and use of other tobacco products is similar; and susceptibility to initiate smoking among never smokers is similar among boys and girls and is higher than cigarette smoking in the majority of sites. Approximately half of the students reported that they were exposed to secondhand smoke in public places during the week preceding the survey. Approximately eight in 10 favor a ban on smoking in public places. Approximately two in 10 students own an object with a cigarette brand logo on it, and one in 10 students have been offered free cigarettes by a tobacco company representative. Approximately seven in 10 students who smoke reported that they wanted to stop smoking. Approximately seven in 10 students who smoked were not refused purchase of cigarettes from a store during the month preceding the survey. Finally, approximately six in 10 students reported having been taught in school about the harmful effects of smoking during the year preceding the survey. INTERPRETATION The findings in this report suggest that interventions that decrease tobacco use among youth (e.g., increasing excise taxes, media campaigns, school programs in conjunction with community interventions, and community interventions that decrease minors' access to tobacco) must be broad-based, focused on boys and girls, and have components directed toward prevention and cessation. If effective programs are not developed and implemented soon, future morbidity and mortality attributed to tobacco probably will increase. PUBLIC HEALTH ACTION The synergy between countries in passing tobacco-control laws, regulations, or decrees; ratifying the WHO Framework Convention on Tobacco Control; and conducting GYTS offers a unique opportunity to develop, implement, and evaluate comprehensive tobacco-control policy that can be helpful to each country. The challenge for each country is to develop, implement, and evaluate a tobacco-control program and make changes where necessary.

Abstract
OBJECTIVES To compare tobacco control policies independently and as a package through a simulation model to project smoking prevalence and associated future premature mortality in Argentina beginning in 2001. METHODS A simulation model of tobacco control policies known as SimSmoke was modified using data for Argentina on population, fertility and mortality, smoking prevalence, and tobacco control policies in effect between 2001 and 2004. We used the Argentina Tobacco Policy Simulation model (ATPSM) to consider the effect on smoking prevalence of changes in taxes and prices, clean air laws, media campaigns, cessation programs, and youth access policies on smoking initiation and cessation rates. Smoking prevalence and relative risks of smoking were used to estimate smoking-attributable mortality. The ATPSM was used to project smoking prevalence and smoking-attributable deaths during the period 2001-2034. RESULTS The largest reductions in smoking prevalence and premature mortality were predicted for a comprehensive tobacco control policy package, but relative reductions of as much as 30% were also predicted for large tax increases. Adding a media campaign along with programs to publicize and enforce clean air laws, advertising bans, and youth access laws would further reduce smoking rates by up to 45% by the year 2034, and would save almost 16 000 lives per year. CONCLUSIONS Tobacco control policies can substantially reduce smoking rates, which can save many lives. Without such policies, deaths from smoking, and associated medical costs, will increase. The ATPSM is expected to provide guidance in filling the most important information gaps pertinent to both modeling and policy-making in Argentina, e.g., the lack of data on initiation and cessation rates, and the need for studies on the impact of policies. Similar models might be developed for other Latin American countries.

Abstract
BACKGROUND Smoking is the main risk factor for Chronic Obstructive Pulmonary Disease (COPD), an important cause of morbidity and mortality. AIM To estimate smoking attributable risk and population attributable risk in COPD patients attended in Public Health Services of Santiago. MATERIALS AND METHODS A case control study matched by sex and age was carried out. Crude and adjusted attributable risks as well as population attributable risk were estimated, controlled by potential confounders and by interaction variables. RESULTS Mean ages for cases and controls were 68 and 67 years respectively. When compared to the control group, COPD patients had a higher smoking prevalence (at least 100 cigarettes in their life span: 89.7% vs 60.3%; p <0.01). Among COPD patients, heavy smokers proportion was 4 times higher than in controls, they smoked for more years (43 vs 31; p <0.01) and more cigarettes per day (18 vs 5; p <0.01). Adjusted attributable risk was 87% (95% Confidence Interval (CI): 63.7-94.8). If a patient smoked at least 100 cigarettes in his/her life span and this risk was 92.7% (CI: 82.4-96.9) for heavy smokers. Projecting this index to Santiago inhabitants, about 87,000 individuals older than 40 years would be suffering COPD due to smoking. CONCLUSIONS This article confirms the strong association between smoking and COPD. Attributable risks are high and significant, even when they are adjusted by confounding variables. Women had a higher risk than men, at lower levels of tobacco consumption.

Comparison of two quantitative GC-MS methods for analysis of tomato aroma based on purge-and-trap and on solid-phase microextraction. Anal Bioanal Chem 2006; 385:1255-64. [PMID: 16670892 DOI: 10.1007/s00216-006-0410-9] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2005] [Revised: 02/28/2006] [Accepted: 03/03/2006] [Indexed: 11/28/2022]
Abstract
Two analytical procedures, one based on purge-and-trap and the other on solid phase microextraction, both followed by GC-MS measurement using an ion-trap mass spectrometer in the electron impact mode, have been developed for determination and quantitation of up to 39 aroma compounds in fresh tomatoes. The method based on purge-and-trap for isolation of the volatile compounds uses Tenax as adsorbent and a hexane-diethyl ether mixture as solvent for elution. The method was validated for linearity, precision (better than 20% for most compounds), and limit of detection, which was approximately 1 ng g(-1). This method enabled identification of up to 30 compounds in real samples. Use of SPME was considered as an alternative, to simplify sample treatment while maintaining the information level for the samples (e.g. the number of compounds detected) and quality of quantitation. A procedure based on SPME using a Carboxen/polydimethylsiloxane fibre was developed and validated for determination of 29 aroma compounds; precision was better than 20% and limits of detection ranged from 4 to 30 ng g(-1).

Abstract
CONTEXT The success of measures to restrict smoking in indoor environments and the intensity of enforcement vary among countries around the world. In 2001, the Pan American Health Organization (PAHO) launched the Smoke-Free Americas Initiative to build capacity to achieve smoke-free environments in Latin America and the Caribbean. OBJECTIVE To assess secondhand smoke concentrations in public places in the capital cities of Argentina, Brazil, Chile, Costa Rica, Paraguay, Peru, and Uruguay in conjunction with the Smoke-Free Americas Initiative. DESIGN AND SETTING Multicountry assessment of vapor-phase nicotine concentrations using a common protocol in all 7 Latin American countries. A total of 633 sampling devices were placed for 7 to 14 days in 1 hospital, 2 secondary schools, 1 city government building, 1 airport (2 in Argentina), and restaurants and bars in each country. MAIN OUTCOME MEASURE Concentrations of airborne nicotine. RESULTS Airborne nicotine was detected in most (94%) of the locations surveyed. By country, Argentina and Uruguay had the highest median concentrations in most environments (eg, in hospitals: 1.33 [interquartile range [IQR], 0.51-3.12] microg/m3 and 0.8 [IQR, 0.30-1.69] microg/m3, respectively). Overall, bars and restaurants had the highest median concentrations (3.65 [IQR, 1.55-5.12] microg/m3 and 1.24 [IQR, 0.41-2.48] microg/m3, respectively). Nicotine concentrations were also found in a number of key, sentinel buildings, including 95% (155/163) of hospital samples (in the physicians' and nurses' stations the median was 0.27 [IQR, 0.02-1.94] microg/m3), schools, government buildings, and/or airports in most countries. CONCLUSIONS The finding of airborne nicotine in critical locations in Latin America provides a basis for enforcing smoke-free initiatives and for strengthening the protection of the public from unwanted exposure to secondhand smoke.
