AIMS To measure the effects of changing attributes of pictorial health warning labels (HWLs) on cigarette packs in a country that has already implemented pictorial HWLs. MEASURES For each choice set, participants were presented with two cigarette packs and asked the following three questions: (1) 'If only these two cigarette packs were available, which would you buy?'; (2) 'Each of these two packs has warnings on the front and back about the health effects of smoking. Which of these warnings best informs you about the dangers from smoking?'; and (3) 'Which warning most makes you think about quitting smoking?'. As recommended for best practices in discrete choice experiments, each of these questions was followed by an 'opt-out' question for participants to indicate whether they really believed there was a difference between the options presented (i.e. 'Would you really choose one of them?'; 'Do you really think that either of these warnings informs you about dangers from smoking?'; or 'Do you really think that either of these warnings would make you think about quitting smoking?', respectively). Each choice set could be viewed for as long as the participant wished. For each choice question (i.e. willingness to buy, informative, motivating to quit), the pack chosen was coded as 1 and the other pack as 0, with both packs being given a value of 0 if the participant 'opted out'. DESIGN A within-subject discrete choice experiment that involved systematic manipulation of pictorial HWL size [75 versus 30% (current policy)]; inclusion of imagery on the back of the pack [versus none (current policy)]; and color formatting [black on yellow versus yellow on black (current policy)]. SETTING Mexico, on-line panel. PARTICIPANTS Adult smokers (n = 705). MEASUREMENTS For each choice set, participants selected one pack as having the most informative HWL about smoking harms, the one that makes them think the most about quitting and the one they were most willing to buy. We assessed the independent and interactive effects of HWL attributes on choices. FINDINGS Larger HWL size on the pack front (75 versus 30%) and inclusion of a pictorial image on the pack back were both independently associated with lower willingness to buy a pack [b = -0.228, standard error (SE) = 0.023 and -0.089, SE = 0.016, respectively] and greater perception of an HWL as informative (b = 0.214, SE = 0.022, and 0.191, SE = 0.017, respectively) and motivating to quit (b = 0.251, SE = 0.023 and 0.194, SE = 0.017, respectively). HWL with black text and yellow background were perceived as less informative (b = -0.037, SE = 0.016) and less motivating to quit (b = -0.032, SE = 0.015) compared with yellow text on a black background. CONCLUSIONS Among adult Mexican smokers, pictorial health warning labels on cigarette packages that are larger or cover both sides of the pack appear more effective at lowering purchase intentions and increasing risk perceptions and motivation to quit than smaller health warning labels or health warning labels with imagery only on the pack front.

Purpose: This study aimed to characterize the patterns of smoking, e-cigarette use, other substance use (alcohol and marijuana), and depression by sexual orientation in a sample of Mexican adult smokers. Methods: Data came from a 2018–2020 (six waves) online survey of adult smokers, recruited from a commercial research panel (92.5% heterosexual, n = 4786; 3.1% lesbian/gay, n = 160; and 4.4% bisexual, n = 229). After stratifying the data by sex, logistic, multinomial, and linear logistic regression models were estimated (depending on the outcome), including as independent variables sexual orientation (i.e., gay/lesbian, bisexual, heterosexual = Reference), age, education, household income, and wave. Results: Being a gay male was independently associated with greater smoking dependence (β = 0.20; 95% confidence interval [CI]: 0.02 to 0.39), greater likelihood of preference for flavored capsule cigarettes (adjusted odds ratio [AOR] = 2.10, 95% CI: 1.33 to 3.28), and depression diagnosis (AOR = 2.85, 95% CI: 1.64 to 4.95). Bisexual males had higher e-cigarette dependence (β = 0.37; 95% CI: 0.05 to 0.68, among dual users only) and were more likely to have been diagnosed with depression (AOR = 2.34, 95% CI: 1.30 to 4.18). Lesbian females were more likely to prefer menthol cigarettes (AOR = 3.32, 95% CI: 1.60 to 6.86), to have used marijuana more than once (AOR = 3.23, 95% CI: 1.83 to 5.72), and to have depressive symptoms (AOR = 1.85, 95% CI: 1.04 to 3.29). Bisexual females had a greater likelihood of depressive symptoms (AOR = 1.71, 95% CI: 1.14 to 2.56) and depression diagnosis (AOR = 2.22, 95% CI: 1.43 to 3.42). Conclusion: Lesbian, gay, and bisexual adult smokers in Mexico appear more likely than heterosexual adult smokers to report having depression. Substance use and depression among sexual minority populations need to be addressed further.

Conclusion. Eluso dual se asocio con un perfil de riesgo mas alto; este perfil es mas prominente en usuarios duales que usan cigarros electronicos con mayor frecuencia. EnglishObjective. To describe the profile and patterns of dual uses (n=954) and exclusive cigarette users (n=2 070) and determine the correlates of more frequent e-cigarette use among dual users and their reasons for e-cigarette use. Materials andmethods. An online survey of Mexican adult smokers. Logistic models regressed dual-use (exclusive smoking vs. dual user) on sociodemographic, smoking varia-bles and substance use behaviors. We conducted censorial binomial models to estimate the correlates of frequency of e-cigarette use among dual users. Results. Dual users were younger had higher education (AOR=2.22) and higher levels of smoking dependence (AOR=1.31), preferred cigarettes with flavor capsules (AOR=1.58) and had recently attempted to quit smoking (AOR=1.38). Marijuana use and being daily smokers were correlates of higher frequency of use among dual users. Conclusion. Dual users had a higher risk profile than exclusive smokers, which was even more prominent in dual-users who used e-cigarettes frequently.

Evaluate the patterns of e-cigarette use andtheir association with smoking behavior.We analyzed data from a population-based representative cohort of adult smokers who participated in the International Tobacco Control Policy Evaluation Surveys in Mexico. The analytic sample (n=760) was restricted to participants who were followed up from wave 6 (2012) to wave 7 (2014-2015). GEE models regressed e-cigarette use at follow-up and changes in cigarettes per day (CPD) between waves, on baseline sociodemographic variables, smoking status (daily, non-daily, quit), e-cigarette trial, and quit intentions.Smokers who were younger, had a higher income, and had tried e-cigarettes at baseline were more likely to be current e-cigarette users at follow-up. Ecigarette use at follow-up was not associated with a change in CPD over time.E-cigarette use does not appear to have promoted smoking cessation or reduction in this sample of Mexican smokers.Evaluar los patrones de uso de cigarros electrónicos y su asociación con el uso de tabaco.Se usaron datos de una cohorte de fumadores adultos mexicanos de la Encuesta Internacional de Evaluación de Políticas del Control del Tabaco (n=760) con seguimiento de la ronda 6 (2012) a la 7 (2014-2015). Se usaron modelos GEE para evaluar el uso de cigarros electrónicos y el cambio en el número de cigarros por día (CPD) en variables de la basal sobre características sociodemográficas, consumo del cigarro (diario, no diario, haber dejado de fumar), prueba de cigarros electrónicos e intención de dejar de fumar.umadores jóvenes, con ingresos altos y que probaron cigarros electrónicos en la medición basal tenían más posibilidad de usar cigarros electrónicos. No se encontró relación entre uso de cigarros electrónicos y cambio en CPD.Los cigarros electrónicos no parecen promover el abandono ni la reducción del consumo de cigarros en esta muestra de fumadores mexicanos.

IntroductionCigarette packaging is a primary channel for tobacco advertising, particularly in countries where traditional channels are restricted. The current study evaluated the independent and interactive effects of cigarette packaging and health warning label (HWL) characteristics on perceived appeal of cigarette brands for early adolescents in Mexico.MethodsA discrete choice experiment (DCE) was conducted with early adolescents, aged 12–14 years (n=4251). The DCE involved a 3×25 design with six attributes: brand (Marlboro, Pall Mall, Camel), tobacco flavour (regular, menthol), flavour capsule (none, 1 or 2 capsules), presence of descriptive terms, branding (vs plain packaging), HWL size (30%, 75%) and HWL content (emphysema vs mouth cancer). Participants viewed eight sets of three cigarette packs and selected a pack in each set that: (1) is most/least attractive, (2) they are most/least interested in trying or (3) is most/least harmful, with a no difference option.ResultsParticipants perceived packs as less attractive, less interesting to try and more harmful if they had plain packaging or had larger HWLs, with the effect being most pronounced when plain packaging is combined with larger HWLs. For attractiveness, plain packaging had the biggest influence on choice (43%), followed by HWL size (19%). Interest in trying was most influenced by brand name (34%), followed by plain packaging (29%). Perceived harm was most influenced by brand name (30%), followed by HWL size (29%).ConclusionIncreasing the size of HWLs and implementing plain packaging appear to reduce the appeal of cigarettes to early adolescents. Countries should adopt these policies to minimise the impact of tobacco marketing.

Background: We evaluated smokers&rsquo, perceptions of heated tobacco products (HTPs) in Mexico, where industry publically lobbied to introduce HTPs into this country that banned both HTPs and e-cigarettes. Methods: Online surveys (November 2018 to July 2019) were analyzed from adults who only smoked cigarettes (n = 2091) or who smoked and used e-cigarettes (&ldquo, dual users&rdquo, n = 1128). Logistic models regressed HTP awareness, interest to trying HTPs, and having seen HTPs for sale (only among aware participants) on sociodemographics and tobacco-related variables. Results: Of the 17.1% who were aware of HTPs, 52.7% reported having seen HTPs for sale. Of all respondents, 75% were somewhat or very interested in trying HTPs. Compared to their counterparts, more frequent smokers, dual users, those exposed to online e-cigarette ads, and those with friends who used e-cigarettes were both more aware of and interested in trying HTPs. Greater awareness was also associated with higher education, recent attempts to quit, receipt of email e-cigarette ads, and smoking among friends and family. Seeing HTPs for sale was higher for those who recently attempted to quit, were exposed to e-cigarette ads online or by email, or had friends who used e-cigarettes. Conclusion: Interest in HTPs is high among smokers in Mexico, which already has a large black market for illegal e-cigarettes. HTPs use should be monitored in this context, especially given the public health impacts of HTPs are unclear.

This study describes the prevalence and correlates of adult smokers&rsquo, discussions about electronic cigarettes (e-cigarettes) with health professionals (HPs), including whether these discussions may lead smokers and vapers to use e-cigarettes for smoking cessation. Methods: We analyzed data from an online survey of Mexican smokers recruited from a consumer panel for marketing research. Participants who had visited an HP in the prior four months (n = 1073) were asked about discussions of e-cigarettes during that visit and whether this led them to try to quit. Logistic models regressed these variables on socio-demographics and tobacco use-related variables. Results: Smokers who also used e-cigarettes (i.e., dual users) were more likely than exclusive smokers to have discussed e-cigarettes with their HP (adjusted odds ratio (AOR) = 3.96, 95% C.I. 2.73, 5.74), as were those who had recently attempted to quit smoking (AOR = 1.89, 95% C.I. 1.33, 2.7). Of smokers who had discussed e-cigarettes, 53.3% reported that the discussion led them to use e-cigarettes in their quit attempt. Also, dual users (AOR = 2.6, 95% C.I. 1.5, 4.5) and daily smokers (&gt, 5 cigarettes per day) (AOR = 3.62, 95% C.I. 1.9, 6.8) were more likely to report being led by their HP to use e-cigarettes in the quit attempt compared to exclusive smokers and non-daily smokers, respectively. Conclusions: Discussions between HP and smokers about e-cigarettes were relatively common in Mexico, where e-cigarettes are banned. These discussions appear driven by the use of e-cigarettes, as well as by greater smoking frequency and intentions to quit smoking.

Mexico is one of the countries most affected by COVID-19. Studies have found that smoking behaviors have been impacted by the pandemic as well, however, results have varied across studies, and it remains unclear what is causing the changes. This study of an open cohort of smokers recruited from a consumer panel (n = 2753) examined changes in cigarettes per day (CPD), daily vs. non-daily smoking, recent quit attempts, perceived stress, depression, and perceived severity of COVID-19 at two points during the pandemic: March and July 2020. Differences in CPD between waves were estimated with Poisson regression using generalized estimating equations (GEE). Differences in perceived stress were estimated with linear regression using GEE, and differences in recent quit attempts, depression, and perceived severity of COVID-19 were estimated using separate logistic regression GEE models. Rates of depression were higher in July compared to March (AOR = 1.55, 95% C.I. 1.31–1.85), and the likelihood of recent quit attempt was lower in July compared to March (AOR = 0.85, 95% C.I. 0.75–0.98). There was no statistically significant change in CPD, daily smoking, or perceived stress. Perceived COVID-19 severity for oneself increased significantly (AOR: 1.24, 95% C.I. 1.02–1.52), however, the perceived COVID-19 severity for smokers remained constant. Our study suggests that as the COVID-19 pandemic expanded in Mexico, smoking frequency remained stable, and quit attempts decreased, even as adult smokers increasingly perceived infection with COVID-19 for themselves as severe. These results can aid in the development of health communication strategies to educate smokers about their risk for COVID-19, potentially capitalizing on concerns that stem from this syndemic of communicable and smoking-related non-communicable disease.

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.

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

Introduction The popularity of electronic cigarettes (e-cigarettes) has increased worldwide among youth, even in countries like Mexico that ban them. This study aimed to assess the correlates of e-cigarette use frequency among Mexican students who currently use ecigarettes, as well as to describe their reasons for use. Methods Data were analyzed from a school-based survey of 57 public middle schools from the three largest cities in Mexico. Primary analyses were confined to those who used e-cigarettes in the prior 30 days. Censored binomial models for truncated distributions were estimated, regressing lifetime and past month frequency of use on participant sociodemographics, other substance use (smoking, alcohol, drugs), technophilia (appeal of new technologies), characteristics of e-cigarettes used, and family's and friends' use of nicotine products. Results Being male (APR = 1.93 95% CI 1.53–2.44), using drugs, (APR = 1.51 95% CI 1.03–2.20), higher technophilia (APR = 1.66 CI 1.21–2.29) and having a family member who uses e-cigarettes and cigarettes were associated with more frequent use in the last month. Students who preferred fruit and combined flavors had used e-cigarettes more often in their lifetime compared to students who preferred mint/menthol flavors. Conclusions Some risk factors for more frequent e-cigarette use among Mexican youth are similar to those foudn in other countries (having relatives who use ecigarettes, using drugs, and use of fruit flavors). Additionally, the novel measure of technophilia was positively associated with frequency of e-cigarette use. The appeal of flavors, in particular, suggests the importance of reducing youth access to flavored products to impede product initiation and progression.

Electronic cigarettes, handheld devices that generate an aerosol that may contain nicotine by heating a solution or e-liquid, have been increasingly used especially in the young population. The aerosol's composition is determined by temperature, and by the substances contained in the heated liquid: glycerin, propylene glycol, nicotine in variable concentrations, flavoring agents, and other non-nicotine compounds. >80 compounds (including known toxics, e.g., formaldehyde, acetaldehyde, metallic nanoparticles, and acrolein) have been found in e-liquid and aerosols. Airway irritation, mucus hypersecretion, and inflammatory response, including systemic changes, have been observed after the exposure to e-cigarettes, leading to an increase in respiratory symptoms and changes in respiratory function and the host defense mechanisms. E-cigarette has been linked with an increase of symptoms in individuals with asthma, cystic fibrosis, and chronic obstructive pulmonary disease. One of the major concerns in public health is the rise in e-cigarette experimentation among never-smokers, especially children and adolescents, which leads to nicotine addiction and increases the chances of becoming with time a conventional smoker. There is an urgent need to regulate e-cigarettes and electronic nicotine delivery systems, at least with the same restrictions to those applied to tobacco products, and not to consider them as harmless products.

Background. This study examined how risk perceptions and social norms around e-cigarettes are associated with susceptibility (i.e., openness to using the product in the next 12 months) of e-cigarettes and smoking among adolescents. Methods. We analyzed data from a 2016 representative survey of 8,718 middle school students in Mexico. The study sample was restricted to students who had tried neither e-cigarettes nor cigarettes, ( N = 4471). Students reported on the risks of e-cigarettes compared with those of cigarettes, and product-specific norms were measured by assessing current use by family members, at least one close friend, and, for e-cigarettes, by perceived societal acceptability of use (i.e., acceptability among people in general). Adjusted prevalence ratios (APR) were estimated using generalized estimating equation models that regressed e-cigarette societal acceptability on study variables. Adjusted generalized estimating equation models also regressed susceptibility for each product on study variables. Results. Susceptibility to both e-cigarettes and smoking was higher among students who reported that their family and friends used only cigarettes or both products when compared with students whose family and friends did not use either of these products. Friend use of e-cigarettes was associated with e-cigarette susceptibility (APR = 1.33) but not smoking susceptibility. Students who perceived that e-cigarettes were less risky than smoking were more susceptible to e-cigarette use (APR = 1.45). The association between e-cigarette susceptibility and friend or family use was not mediated by societal acceptability. Conclusions. E-cigarette use among family and peers appears associated with susceptibility to use e-cigarettes in a way that is similar to the patterns found for cigarettes. However, the influences appear somewhat specific to the type of product that network members use.

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 adolescents9 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.

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.

Purpose Develop and validate a scale that measures Technophilia (positive orientation toward new technology) and use it to address orientation toward new technologies to explain e-cigarette trial and adoption, especially in relatively low risk adolescents. Methods Survey data were obtained from students of the three largest cities in Mexico (n = 8123). We developed eight questions involving access, use and pleasure from different electronic media to measure technophilia. Exploratory factor analysis (EFA) was conducted. Linear GEE models were used when regressing technophilia on covariates. When regressing e-cigarette and conventional cigarette trial and use, logistic GEE models were used. Finally, we used multinomial logistic regression to evaluate the associations between technophilia and e-cigarettes as the first tobacco product. Results Technophilia were correlated with theoretically-related variables. Unadjusted and adjusted models regressing e-cigarette trial and use indicated that students in the highest quartile for technophilia were more likely to have tried e-cigarettes compared with the lowest quartile (AORQ4 vs Q1 = 1.36, 95% CI 1.14–1.62). Technophilia was not independently associated with current e-cigarette use in adjusted models. Students with higher technophilia were more likely to have first tried e-cigarettes in both crude and adjusted models (AORQ4vQ1 = 1.66, 95% CI 1.20–2.31; AORQ3vQ1 = 1.43, 95% CI 1.02–2.01). Technophilia did not have a statistically significant, independent association with first use of other tobacco products. Conclusion This study suggests that technophilia is associated with trial of e-cigarettes among youth. The measure we developed appears useful for understanding why some youth are open to trying novel, technologically oriented ways to consume nicotine.

This study aimed to assess sex differences in predictors for becoming a current exclusive electronic cigarette (e-cigarette) user, current exclusive smoker, or current dual user (concurrent smoking and e-cigarette use). This longitudinal study included 2399 females and 2177 males who had tried neither cigarettes nor e-cigarettes at baseline and attended 57 middle schools in the three largest cities in Mexico. We estimated multinomial logistic models stratified by sex. At follow-up, the prevalence of current exclusive e-cigarette use was 6.4% for males and 5.5% for females, current exclusive smoking was similar among males (3.6%) and females (3.5%), dual use was 2.4% females and 1.8% males. In the adjusted model, current e-cigarette use among females was associated with baseline current drinking (ARR = 1.85, p &lt, 0.05), having a job (ARR = 1.99, 0.05), higher technophilia (ARR = 1.27, 0.05), and higher positive smoking expectancies (ARR = 1.39, 0.05). Among males, only having friends who smoke cigarettes at baseline was a significant predictor of current exclusive e-cigarette use at follow-up (ARR = 1.44, 0.05). For both sexes, current exclusive smoking at follow-up was associated with baseline current drinking (male ARR = 2.56, 0.05, female ARR = 2.31, 0.05) and, among males, only with having a parent who smoked (ARR = 1.64, 0.05). For both sexes, dual use at follow-up was associated with baseline current drinking (male ARR = 3.52, 0.005, female ARR = 2.77, 0.05), among females, with having paid work (ARR = 2.50, 0.001), and among males, with parental smoking (ARR = 3.20, 0.05). Results suggested both common and different risk factors by sex, suggesting that interventions may need to consider targeting sex differences.

Background E-cigarettes have had a strong growth in Mexico, especially among adolescents. These products are advertised as technology advanced products and their increased use may reflect a tendency to adopt new technologies. The concept of "technophilia" draws attention to the "pleasure, affection, and emotional qualities" that accompanies new technology. The aim of this study is to explore and validate a technophilia index among a cohort of Mexican youth, and to evaluate the association with e-cigarette trial and use. Methods We analyzed cross-sectional data from 8747 students from the three largest cities in Mexico. To develop the technophilia index we evaluated eight questions related to internet use. To validate this scale, we used an explanatory factor analysis on the overall item set. We used linear and multinomial logistic regressions to evaluate the association between the technophilia index and e-cigarette trial/use, and having used e-cigarette as the first tobacco product. Results Study results showed a dose-response association between technophilia index and e-cigarette trial (OR=1.48, 95% CI 1.26-1.75, Quartile 4 vs. Quartile 1). Moreover, Mexican adolescents with high levels of technophilia were more likely to have used e-cigarettes as their first tobacco product (OR=1.78, 95% CI 1.31-2.42, Quartile 4 vs. Quartile 1). Conclusions Results from this study suggest that e-cigarette trial is characterized by greater technophilia among youth. This study highlights the need for research in this area, so that effective strategies may be developed to address these risk factors.

Purpose This study evaluated whether e-cigarette trial among Mexican adolescents increased the likelihood of trial and use of conventional cigarettes or marijuana use at follow-up. Method A school-based longitudinal survey was conducted in 60 public middle schools from the three largest cities in Mexico. Students (12–13 years old) were surveyed in 2015 and followed up 20 months later (n = 6574). Generalized estimating equations models were used to evaluate the association between e-cigarette trial at baseline and conventional cigarettes smoking and marijuana use at follow-up. Result Adolescents who had tried e-cigarettes (but not cigarettes) at baseline were more likely to have tried conventional cigarettes at followup compared to adolescents who had tried neither e-cigarettes nor cigarettes (43% vs. 24%, respectively; RR 1.41, 95% CI 1.18-1.70). We also found that adolescents who had tried both conventional cigarettes and e-cigarettes at baseline were more likely to have tried marijuana at follow-up compared to adolescents who had tried neither tobacco product (20% vs. 4%, respectively; RR 2.67, 95% CI 1.78–4.02). Trial of only e-cigarettes was not independently associated with marijuana use at followup. Conclusions Adolescents who had tried e-cigarettes were more likely to have tried conventional cigarettes and marijuana 20 months later. Although e-cigarettes have been banned in Mexico, it is likely that additional policies and public health campaigns are needed to reduce adolescent use of e-cigarettes and its consequences.

Background Video games are widely used by children and adolescents and have become a significant source of exposure to sexual content. Despite evidence of the important role of media in the development of sexual attitudes and behaviours, little attention has been paid to monitor sexual content in video games. Methods: Data was obtained about sexual content and rating for 23 722 video games from 1994 to 2013 from the Entertainment Software Rating Board database; release dates and information on the top 100 selling video games was also obtained. A yearly prevalence of sexual content according to rating categories was calculated. Trends and comparisons were estimated using Joinpoint regression. Results: Sexual content was present in 13% of the video games. Games rated ‘Mature’ had the highest prevalence of sexual content (34.5%) followed by ‘Teen’ (30.7%) and ‘E10+’ (21.3%). Over time, sexual content decreased in the ‘Everyone’ category, ‘E10+’ maintained a low prevalence and ‘Teen’ and ‘Mature’ showed a marked increase. Both top and non-top video games showed constant increases, with top selling video games having 10.1% more sexual content across the period of study. Conclusion: Over the last 20 years, the prevalence of sexual content has increased in video games with a ‘Teen’ or ‘Mature’ rating. Further studies are needed to quantify the potential association between sexual content in video games and sexual behaviour in children and adolescents.

Los nuevos productos de tabaco, entre los que se incluyen los cigarros electrónicos (denominados “E Cigs”, “e-hookahs”, “mods”, “vape-pens”), los sistemas electrónicos de admi­nistración de nicotina (SEAN), los sistemas similares sin nicotina (SSSN) y los sistemas alternativos de consumo de nicotina (SACN), incursionan en el mercado global con un discurso de reducción del daño y minimización del riesgo. Este manuscrito resume la evidencia científica y una propuesta regulatoria sobre esta innovación tecnológica, con el fin de orientar la toma de decisiones de legisladores, instituciones gubernamentales y la sociedad civil organizada. La evidencia científica concluye que no existe un producto de tabaco seguro para la salud; la naturaleza adictiva de la nicotina y los daños a la salud causados en niños, adolescentes y mujeres embarazadas constituyen el argumento fundamental. Estos nuevos productos promueven la transición al consumo de cigarros combustibles y no han demostrado eficacia para la cesación tabáquica; por el contrario, promueven el uso dual. Toda regulación debe formularse sin la intervención de los fabricantes o instituciones con conflicto de interés y en el marco de la implementación completa e integral del Con­venio Marco de la Organización Mundial de la Salud para el Control del Tabaco.

BACKGROUND: Our objective was to assess whether exposure to alcohol use in films (AUF) is associated with alcohol use susceptibility, current alcohol use, and binge drinking in adolescents from 2 Latin American countries. METHODS: We performed a cross-sectional study with 13,295 middle school students from public and private schools in Mexico and Argentina. Exposure to alcohol use in over 400 contemporary top box office films in each country was estimated using previously validated methods. Outcome measures included current drinking (i.e., any drink in the last 30 days), ever binge drinking (i.e., more than 4 or 5 drinks in a row for females and males, respectively) and, among never drinkers, alcohol susceptibility (i.e., might drink in the next year or accept a drink from a friend). Multivariate models were adjusted for age, sex, parental education, peer drinking, sensation seeking, parenting style, and media access. RESULTS: Mean age was 12.5 years (SD = 0.7), and the prevalence of alcohol consumption and binge drinking was 19.8 and 10.9%, respectively. Mean exposure to alcohol from the film sample was about 7 hours in both countries. Adjusted models indicated independent dose-response associations between higher levels of exposure to AUF and all outcomes; the adjusted odds ratios (aORs) comparing quartiles 4 and 1, 1.99 (95% confidence interval [CI] 1.73 to 2.30) for current drinking, aOR 1.68 (CI 1.39 to 2.02) for binge drinking, and aOR 1.80 (1.52 to 2.12) for alcohol susceptibility. Compared to Mexican adolescents, Argentine adolescents were significantly more likely to have engaged in binge drinking (aOR 1.40, 95% CI 1.12 to 1.76) and, among never drinkers, were more susceptible to try drinking (aOR 1.40, 95% CI 1.20 to 1.64). CONCLUSIONS: Higher levels of exposure to AUF were associated with higher likelihood of alcohol use, binge drinking, and alcohol susceptibility in Latin American adolescents. Language: en

Background Studies that have evaluated tobacco and alcohol portrayals in films have mainly focused on US films. Our aim is to describe tobacco and alcohol portrayals in nationally produced films from six European and two Latin American countries, and compare them with US produced films. Methods A sample of 337 nationally produced and 502 US produced films, consisting of top grossing films from 2004 to 2009 in each country, was content coded for presence of tobacco or alcohol and seconds of tobacco or alcohol use. Logistic and linear regression models were estimated for all films and youth-rated films (Ages 0–14) to assess cross country differences in tobacco and alcohol content, with US films as the reference category. Results Domestically produced films from several countries were more likely than US films to contain any tobacco use both overall (Iceland (OR = 9.29, CI: 1.22–70.89), Italy (OR = 3.58, CI: 1.72–7.43), Argentina (OR = 5.06, CI: 2.13–12.03), Mexico (OR = 4.87, CI: 2.17–10.90)) and for youth-rated films (Germany (OR = 2.24, CI: 1.21–4.16), Iceland (OR = 13.79, CI: 1.80–105.5), Italy (OR = 5.31, CI: 2.54–11.1), and Argentina (OR = 6.9, CI: 0.88–1.34)). Models for alcohol showed few differences compared to US, regardless of rating. Linear regression models for seconds of use in films with tobacco indicated that only Argentine films had more seconds of smoking than US films, regardless of the rating category. For films with alcohol use, Mexican films had higher seconds of alcohol use than US films. Conclusions Smoking was more commonly depicted in films produced outside the US, however there were few differences in the means for smoking screen time in films that contained smoking. This may be partly explained by the prohibition of tobacco product placement in the US. Countries should consider banning paid placement of both products and eliminating subsidies for films with content that promotes tobacco and alcohol use.

Evaluate the effect of the first pictorial warning labels on cigarette packs in Mexican smokers.A population-based representative cohort of smokers from seven Mexican cities was surveyed before (2010) and after (2011) the implementation of pictorial warning labels. To determine the change variables representing the cognitive and behavioral impact of pictorial warnings, bivariate and adjusted generalized estimating equations were estimated. Data from the second survey (2011) were analyzed to determine the factors associated with aided recall of specific pictorial warnings, as well as the factors associated with self-report of the impact that these warnings had.From 2010 to 2011, significant increases were found in smoker's knowledge about smoking risks, the toxic components of tobacco, and the quitline number for receiving cessation assistance. Recall and impact of specific pictorial warnings was generally broad and equally distributed across the smoker population. In comparison with recent ex-smokers interviewed in 2010, more recent ex-smokers in 2011 reported that pack warnings had influenced their decision to quit (RM=2.44, 95% IC 1.27-4.72).The first pictorial warning labels on cigarette packages in Mexico have had a significant impact on knowledge and behavior.

Exposure to tobacco advertisement is associated with smoking initiation among the youth, its elimination is a key objective to effectively curb the tobacco epidemic. Historically, the tobacco industry has pioneered the use of new communication technologies to keep and expand their market. Nowadays, Internet and video games have transcended the entertainment sphere, becoming significant media for massive communication and providing new opportunities for advertisement. The present essay reviews the existing literature on tobacco presence in the Internet and video games to define research and policy tasks required to develop effective means for tobacco advertisement regulation and control.

Determinar en población fumadora el nivel de exposición a la mercadotecnia de la industria tabacalera (IT), a través de diferentes métodos de promocionar sus productos, antes y durante la publicación de la Ley General para el Control del Tabaco (LGCT) en 2008. Material y métodos. Estudio de cohorte en fumadores adultos (n=941 pre-LGCT y n=1 051 post-LGCT) de cuatro ciudades mexicanas. Se realizaron análisis multivariados mediante modelos de ecuaciones de estimación generalizada (GEE). Resultados. Se incrementó el autorreporte de recepción de muestras gratis de cigarros (3.7 a 8.1%), ropa o artículos con marcas o logos (3.6 a 6.4%), haber visto información sobre eventos especiales (1.9 a 4.7%), y publicidad en bares y discotecas para mayores de edad (21.4 a 28%). Se observaron decrementos de publicidad en exteriores (54.7 a 47.2%). Conclusión. Es necesaria una política integral con prohibiciones totales de la publicidad y promoción de los productos de tabaco que integre mayor vigilancia y sanciones para lograr la disminución y prevención del consumo de tabaco.

La exposición a publicidad sobre tabaco está asociada con el inicio en el consumo, particularmente en población joven, por lo que su control es un objetivo clave para reducir la incidencia de tabaquismo. Históricamente, la industria tabacalera ha sido pionera en la utilización de tecnologías de comunicación para posicionarse ante nuevos mercados y mantener la preferencia de los consumidores. Internet y los videojuegos han trascendido el espacio del entretenimiento, convirtiéndose en medios de comunicación masiva con un alto potencial publicitario. El presente artículo hace una revisión de la literatura existente sobre la presencia de tabaco en internet y videojuegos, con la intención de definir líneas de trabajo para desarrollar mecanismos efectivos de regulación y control de la publicidad en estos medios.

Video games provide rich, interactive environments suitable for tobacco promotion.1 2 The WHO-Framework Convention for Tobacco Control (WHO-FCTC) recommends comprehensive bans on ‘… all forms of commercial communication…with the aim, effect or likely effect of promoting a tobacco product or tobacco use .’ WHO-FCTC implementation guidelines cover entertainment media,3 4 yet surprisingly little is known about the importance of video games for promoting tobacco use. Starcraft II: Wings of Liberty, produced by Activision Blizzard, Inc., Santa Monica, California, USA, was the most popular PC military game of 2010, selling 3 million copies worldwide in the first month.5 The game presents 29 battles between humans and aliens, separated by brief scenes or cinematic ‘shorts’, which build a cohesive story, give gamers a pause and represent a reward for advancing in …
