RESUMO

Introduction: Biomass smoke exposure (BSE) is a recognized cause of COPD particularly in rural areas. However, little research has been focused on BSE in suburban areas. Objective: The aim of this study was to determine the prevalence of COPD, respiratory symptoms (RS) and BSE in women living in a suburban area of Mexico City exposed to BSE. Methods: A cross-sectional epidemiological survey of a female population aged >35 years was performed using a multistage cluster sampling strategy. The participants completed questionnaires on RS and COPD risk factors. The COPD prevalence was based on the postbronchodilator forced expiratory volume in the first second (FEV1)/forced vital capacity (FVC) ratio. Of the 1,333 women who completed the respiratory questionnaires, spirometry data were obtained from 1,190, and 969 of these were scored as A-C. Results: The prevalence of BSE was 47%, and the estimated prevalence of COPD was 2.5% for the total population (n=969) and 3.1% for those with BSE only. The spirometry and oximetry values were significantly lower in women with greater exposure levels. The prevalence of RS (cough, phlegm, wheezing and dyspnea) was significantly higher in the women with BSE compared to those without exposure. We concluded that the association of COPD with biomass exposure is not only a rural phenomenon but also may be observed in the suburban areas of the big cities.

RESUMO

El consumo de tabaco es la primera causa de mortalidad prevenible en el mundo. Para combatir esta epidemia, los países miembros de la Organización Mundial de la Salud han firmado, y la mayoría de ellos ratificado, el Convenio Marco para el Control del Tabaco. El artículo 13 de este tratado regula toda forma de publicidad, promoción y patrocinio del tabaco. Las guías para la implementación de este artículo reconocen que la presencia de tabaco en el cine es una forma de promoción de los productos del tabaco dirigida principalmente a los jóvenes. En esta revisión describimos la relación entre la industria del cine y la del tabaco en los últimos 100 años, los estudios de corte transversal y longitudinales que demuestran cómo la exposición a tabaco en el cine induce a los jóvenes a iniciarse en el tabaquismo, y las políticas públicas recomendadas para evitar la presencia de tabaco en el cine, al menos en las películas para niños y adolescentes.

Tobacco use is the primary preventable cause of death and disability in the world. To combat the tobacco epidemic, most countries have signed and ratified the World Health Organzation’s Framework Convention on Tobacco Control (WHO FCTC). Article 13 of this treaty requires implementation of a comprehensive ban on tobacco advertising, promotion and sponsorship. Implementation guidelines for Article 13 recognize that the depiction of tobacco use in commercially-produced films promotes tobacco use amongst young people. In this article we review the relationship between the tobacco industry and the movie industry over the past 100 years; the cross sectional and longitudinal studies that demonstrate a causal relationship between exposure to movie smoking depictions and youth smoking initiation; and the policy interventions recommended by the WHO to limit youth exposure to tobacco in movies.

RESUMO

Introduction: As a result of globalization, youth in Mexico may be exposed to US culture remotely. This remote intercultural contact may influence their movie language orientation and cigarette smoking. To examine how intercultural contact with U.S. culture influences the smoking behaviors of youth in Mexico, this study investigated the influence of English- and Spanish-language movie orientation on movie smoking exposure through US- and Mexico-produced movies. It also examined whether youth movie smoking exposure was associated with higher positive smoking-related expectancies and greater intentions to smoke cigarettes. Methods: Participants were 7524 adolescent never smokers in Mexico (51% female, Mage = 12.39 years) who completed a school-based survey on movie language orientation, movie exposure (from which exposure to tobacco portrayals was estimated), smoking-related expectancies, and smoking susceptibility. Results: Path and mediation analyses indicated that English-language movie orientation was associated with greater movie smoking exposure, leading to more positive smoking-related expectancies and greater youth smoking susceptibility. Conclusion: Consistent with research on the influence of US culture on the smoking of Mexican-heritage youth in the United States, findings suggest that orientation toward English-language movies may put youth in Mexico at risk for smoking initiation. Findings extend existing research on intercultural contact and cigarette smoking with Hispanic youth in the United States to youth in Mexico. Implications for future research are discussed. Implications: This study is one of the first to investigate the influence of remote intercultural contact with US culture on Mexican youth's smoking-related expectancies and susceptibility. This study investigated pathways by which youth's movie language orientation (English vs. Spanish) exposed them to movie smoking through US- and Mexico-produced movies, thereby influencing their smoking-related cognitions. Findings provide initial empirical evidence of a significant association between US remote intercultural contact and smoking among youth in Mexico. An important next step is to investigate how this process unfolds longitudinally and to investigate additional ways youth may engage with US culture to affect their smoking behaviors.

RESUMO

OBJECTIVE:: To examine and compare overall prevalence and time trends in tobacco and alcohol portrayals and brand appearances in youth-rated US and nationally-produced films that were the most successful in Argentina and Mexico from 2004-2012. MATERIALS AND METHODS:: Top-grossing nationally produced films from Argentina (n=73), Mexico (n=85) and the US (n=643) were content analyzed. Logistic regression was used to determine differences between Mexican, Argentine and US produced films. Linear regression models assessed significant cross-country differences in the mean number of tobacco and alcohol seconds. RESULTS:: Films from Mexico and Argentina were more likely than US films to contain tobacco, (OR=4.2; p<0.001) and (OR=7.2; p<0.001). Alcohol was present in 93% of Argentine, 83% in Mexican and 83% US films. CONCLUSIONS:: Smoking and alcohol were highly prevalent in nationally produced films. They may have a significant impact and should be targeted by policies to reduce youth exposure to portrayals of risk behaviors.

RESUMO

The aim of this study was to assess film character portrayals of tobacco and alcohol use in US and nationally-produced films that were popular in Argentina and Mexico from 2004-2012. We performed a content analysis of these films (n=82 Argentine, 91 Mexican, and 908 US films, respectively). Chi-squares and t-tests were used to compare characteristics of characters who smoked or drank by country of movie production. Then data from all countries were pooled, and generalized estimating equation (GEE) models were used to determine independent correlates of character smoking or drinking. There were 480 major characters for Argentine-, 364 for Mexican-, and 4962 for US-produced films. Smoking prevalence among movie characters was similar to population smoking prevalence in Mexico (21%) and Argentina (26%), but about half in the US (11%), where movie product placements are restricted. Movie smoking declined over the period in all three countries. Movie alcohol prevalence was 40-50% across all countries and did not change with time. Demographic predictors of character smoking included: being male, 18 and older, having negative character valence. Movie smoking was not associated with lower SES. Predictors of character drinking included: being age 18 and older and positive character valence. Smoking and drinking predicted each other, illicit drug use, and higher scores for other risk behaviors. This suggests that policy development in Mexico and Argentina may be necessary to reduce the amount of character tobacco and alcohol use in films.

RESUMO

BACKGROUND: Use of flavour capsule varieties (FCVs) of cigarettes has rapidly increased in many countries. Adolescents are attracted to flavours; yet, surprisingly, no quantitative study has explored adolescents' perceptions of these products. OBJECTIVE: To characterise the appeal of FCVs for young adolescents in Mexico. METHODS: In 2015, surveys were conducted with a representative sample of Mexican middle school students (n=10 124; ages 11-16 years; mean 12.4 years). Students viewed and rated packs for FCVs and non-FCVs from major brands (Marlboro, Camel, Pall Mall), with brand names removed. For each pack, students were asked to write the brand name (ie, brand recall), to evaluate pack attractiveness, and to indicate the pack they were most interested in trying (including a 'none' option). Logistic generalised estimating equation (GEE) models regressed brand recall, pack attractiveness and interest in trying on brand and FCV (yes vs no), controlling for sociodemographics and smoking risk factors. RESULTS: Marlboro regular, Camel regular, Camel light and Pall Mall FCVs were most often recalled (25%, 17%, 9%, 8%). Packs for Pall Mall FCVs and Camel FCVs were most often rated as very attractive (13%, 9%, respectively) and of interest for trial (22%, 13%) along with Marlboro regular (14%). In GEE models, FCVs were independently associated with greater attractiveness (adjusted OR (AOR)=1.83, 95% CI 1.72 to 1.94) and interest in trying (AOR=1.74, 95% CI 1.54 to 1.96). Perceived pack attractiveness was also independently associated with greater interest in trying (AOR=5.63, 95% CI 4.74 to 6.68). CONCLUSIONS: FCVs appear to be generating even greater appeal among young adolescents than established non-FCVs in dominant brand families.

RESUMO

PURPOSE: Assess the prevalence and correlates of e-cigarette perceptions and trial among adolescents in Mexico, where e-cigarettes are banned. METHODS: Cross-sectional data were collected in 2015 from a representative sample of middle-school students (n = 10,146). Prevalence of e-cigarette awareness, relative harm, and trial were estimated, adjusting for sampling weights and school-level clustering. Multilevel logistic regression models adjusted for school-level clustering to assess correlates of e-cigarette awareness and trial. Finally, students who had tried only e-cigarettes were compared with students who had tried: (1) conventional cigarettes only; (2) both e-cigarettes and conventional cigarettes (dual triers); and (3) neither cigarette type (never triers). RESULTS: Fifty-one percent of students had heard about e-cigarettes, 19% believed e-cigarettes were less harmful than conventional cigarettes, and 10% had tried them. Independent correlates of e-cigarette awareness and trial included established risk factors for smoking, as well as technophilia (i.e., use of more media technologies) and greater Internet tobacco advertising exposure. Exclusive e-cigarette triers (4%) had significantly higher technophilia, bedroom Internet access, and Internet tobacco advertising exposure compared to conventional cigarette triers (19%) and never triers (71%) but not compared to dual triers (6%), although dual triers had significantly stronger conventional cigarette risk factors. CONCLUSIONS: This study suggests that adolescent e-cigarette awareness and use is high in Mexico, in spite of its e-cigarette ban. A significant number of medium-risk youth have tried e-cigarettes only, suggesting that e-cigarettes could lead to more intensive substance use. Strategies to reduce e-cigarette use should consider reducing exposures to Internet marketing.

RESUMO

OBJECTIVE: We examine whether having depressive symptoms (DS) is associated with different responses to cigarette package health warning labels (HWLs) before and after the implementation of pictorial HWLs in Mexico. METHOD: We analyze data from adult smokers from Wave 4 and Wave 5 (n = 1,340) of the International Tobacco Control Policy Evaluation Project in Mexico. Seven Center for Epidemiological Studies Depression Scale (CES-D) items assessed DS, with scores ≥7 indicating elevated DS. Outcomes included: attention to HWLs, cognitive responses to HWLs, tobacco constituents awareness, putting off smoking due to HWLs, avoidance of HWLs, and awareness of telephone support for cessation (i.e., quitlines). Mixed effects models were used to assess main and interactive effects of DS and time (i.e., survey wave) on each outcome. RESULTS: All HWL responses increased over time, except putting off smoking. Statistically significant interactions were found between DS and time for models of tobacco constituents awareness (b = -0.36, SE = 0.15, p = .022), putting off smoking (OR = 0.41, 95% CI [0.25, 0.66]), avoidance of HWLs (OR = 1.84, 95% CI [1.03, 3.29]), and quitline awareness (OR = 0.35, 95% CI [0.21, 0.56]). Compared to smokers with low DS, smokers with elevated DS reported stronger HWL responses at baseline; however, HWL responses increased over time among smokers with low DS, whereas HWL responses showed little or no change among smokers with elevated DS. DISCUSSION: Population-level increases in HWL responses after pictorial HWLs were introduced in Mexico appeared mostly limited to smokers with low DS. In general, however, smokers with elevated DS reported equivalent or stronger HWL responses than smokers with low DS.

RESUMO

OBJECTIVE: This study assessed the effects of pictorial health warning labels (HWLs) and a linked media campaign in Mexico. METHODS: Cross-sectional data were collected from a population-based sample of 1756 adult smokers, aged 18-55 years, during the initial implementation of pictorial HWLs, which some smokers had seen on cigarette packages while others had seen only the text-based HWLs. Exposure to the campaign and pictorial HWLs was assessed with aided recall methods, and other questions addressed attention and cognitive impact of HWLs, knowledge related to HWL and campaign content, and quit-related thoughts and behaviours. Logistic and linear regression models were estimated to determine associations between key outcomes and intervention exposure. RESULTS: In bivariate and multivariate adjusted models, recall of pictorial HWLs and of the campaign were positively associated with greater attention to and cognitive impact of HWLs, whereas only pictorial HWL exposure was associated with having refrained from smoking due to HWLs. Both recall of pictorial HWLs and of the campaign were independently associated with greater knowledge of secondhand smoke harms and toxic tobacco constituents. Smokers who recalled only the pictorial HWLs were more likely to try to quit than smokers who recalled neither the pictorial HWLs nor the campaign (17% vs 6%, p<0.001). CONCLUSIONS: Consistent with other studies, adult smokers' exposure to new pictorial HWLs in Mexico was associated with psychosocial and behavioural responses related to quit behaviour. Exposure to the complementary media campaign was associated with independent additive effects on campaign-related knowledge, and it enhanced psychosocial responses to pictorial HWLs.
