RESUMEN
BACKGROUND: Sedentary behavior is linked to excess fat mass; however, this association may be inconclusive due to potential measurement errors in self-reported sedentary behavior. OBJECTIVE: To assess the association between changes in sedentary behavior and fat mass in a Cohort of Health Workers (HWCS) from 2004 to 2010. METHODS: A total of 1,285 adults participating in the Cohort of Health Workers were evaluated in 2004 and 2010. Fat mass (kg) was measured by dual X-ray absorptiometry. A self-administered questionnaire was used to estimate the sedentary behavior. Sedentary behavior was also estimated using accelerometry in a sample of 142 health workers. Accelerometry data were used to correct self-reported sedentary behavior using a generalized linear model, which included values for sleeping time, age, sex, sedentary behavior, glucose, and triglycerides. Concordance between both methods was assessed using a kappa and Bland-Altman analysis. Once sedentary behavior was corrected, the values were used to evaluate the association between changes in sedentary behavior and body fat mass using a fixed effect model in the cohort, adjusting for confounders. RESULTS: Self-reported sedentary behavior was 2.8 ± 1.8 and 2.3 ± 1.6 h/day, and body fat mass was 24.9 ± 8.1 and 26.8 ± 8.5 kg in 2004 and 2010, respectively. After applying the correction model, the self-reported sedentary behavior was 7.6 ± 1.2 and 7.5 ± 1.2 h/day in 2004 and 2010, respectively. For every hour increase in corrected sedentary behavior, there was an observed increase of 0.847 (p > 0.001) kg in body fat mass during the 6.8 years in the Cohort of Health Workers from 2004 to 2010. Conversely, non-corrected self-reported sedentary behavior was associated with a non-significant reduction of 0.097 kg (p = 0.228) for every hour of sedentary behavior. CONCLUSIONS: Increased sedentary behavior was associated with increased body fat mass when corrected self-reported sedentary behavior was used. Implementing public health strategies to reduce sedentary behavior is imperative.

INTRODUCTION: Reasons for using and stopping the use of e-cigarettes and their associations with transitions in nicotine product use are relatively unknown in countries with e-cigarette bans, such as Mexico. METHODS: Data comes from an open cohort of people who smoke in Mexico, surveyed every 4 months from November 2018 to November 2021. Those who smoked and used e-cigarettes at time t (n=904 individuals, 1653 observations) were categorised at 4-month follow-up (t+1): (1) continued 'dual use', (2) exclusive smoking, (3) exclusive use of e-cigarettes or neither product. For people who formerly used e-cigarettes at time t (n=332 individuals, 372 observations), follow-up categories were: (1) continued exclusive smoking; (2) re-initiated e-cigarette use. Multinomial and logistic models regressed follow-up status (ref=status at time t) on reasons for using or stopping e-cigarette use, respectively, at time t, adjusting for covariates. RESULTS: The most prevalent reasons for current e-cigarette use were 'they were less harmful to others' (40.5%) and 'enjoyable' (39.0%). Those who reported using e-cigarettes because they were less harmful to others (Adjusted Relative Risk Ratio (ARRR)=0.67), more enjoyable (ARRR=0.52), could help them to quit smoking (ARRR=0.65), or to control weight (ARRR=0.46) were less likely to return to exclusively smoking. Among people who formerly used e-cigarettes, lack of satisfaction was the primary reason for stopping e-cigarette use (32%) and those who reported this were less likely to start using e-cigarettes again at follow-up (Adjusted Odds Ratio (AOR)=0.58). CONCLUSIONS: Specific reasons for using and stopping e-cigarettes predict changes in smoking and e-cigarette use, and targeting these beliefs could promote desired behaviour changes.
RESUMEN
INTRODUCTION: This study assessed quit attempts among adults who use cigarettes either exclusively or with e-cigarettes in Mexico, where non-daily smoking predominates. METHODS: An open cohort of Mexican adults who smoke was surveyed every four months from November 2018 to March 2021. Participants followed to the next survey were analyzed (n = 2220 individuals, 4560 observations). Multinomial logistic models regressed smoking quit attempts reported at the followup survey (ref = no attempt; tried to quit; sustained attempt of ≥30 days) on e-cigarette use frequency (none = ref; 1-2 days/week; ≥3 days/week), adjusting for sociodemographics and smoking-related variables. Additional models subdivided e-cigarette users by intentions to quit smoking in the next six months (i.e., yes/no), use of nicotine (i.e., yes/no), and vaping device used (i.e., open/closed). RESULTS: At 4-month follow-up, 32.7 % had tried to quit, and 2.9 % had quit for 30 days or more. Compared to those who smoke exclusively, occasional, and frequent e-cigarette users were more likely to try to quit (Adjusted Relative Risk Ratio or ARRR = 1.26 and 1.66, respectively) but no more likely to sustain their quit attempt. Among those who intended to quit smoking, e-cigarette users were no more likely to either try or sustain quit attempts. Furthermore, use of e-cigarettes with nicotine (59.6 %) was unassociated with cessation except that those who frequently used e-cigarettes with nicotine were more likely to try to quit than those who smoke exclusively (ARRR = 1.88). Device type used was not differentially associated with outcomes. CONCLUSIONS: Mexicans who smoke and use e-cigarettes appear more likely than those who smoke exclusively to try to quit but not to sustain abstinence.

INTRODUCTION: Heated tobacco products (HTPs) are promoted as less harmful than cigarettes; nonetheless, whether HTPs help smokers quit is uncertain. METHODS: Data from 4067 Mexican adult smokers surveyed longitudinally every four months (November 2019-March 2021) were analyzed. Mixed-effects multinomial models regressed HTP use frequency (no use=reference; monthly; weekly; and daily use) on sociodemographics and tobacco/nicotine-related variables. Among participants who completed at least two surveys (n=2900) over four months, the duration of their longest smoking quit attempt (SQA) between surveys (SQAs: <30 days; ≥30 days; no SQA=reference) was regressed on HTP use frequency, and changes in the number of cigarettes smoked per day were regressed on HTP initiation between surveys, adjusting for covariates. RESULTS: Consistent predictors of all HTP use frequencies (monthly, weekly, or daily vs no use) were daily smoking >5 cigarettes (ARRR=1.69 [95% CI: 1.12-2.55], 1.88 [95% CI: 1.26-2.81] and 6.46 [95% CI: 3.33-12.52], respectively); e-cigarette use (ARRR =5.68 [95% CI: 3.38-9.53], 6.54 [95% CI: 4.06-10.55] and 2.59 [95% CI: 1.26-5.30]); lower HTP risk perceptions (ARRR=2.12 [95% CI: 1.50-30.00], 2.25 [95% CI: 1.63-3.10] and 2.00 [95% CI: 1.25-3.22]); exposure to HTP information inside (ARRR=2.13 [95% CI: 1.44-3.15], 2.13 [95% CI: 1.49-3.05] and 3.72 [95% CI: 2.28-6.09]) and outside stores (ARRR=2.36 [95% CI: 1.56-3.57], 2.32 [95% CI: 1.65-3.25] and 2.44 [95% CI: 1.41-4.24]) where tobacco is sold; having family (ARRR=2.46 [95% CI: 1.54-3.91], 2.90 [95% CI: 1.93-4.37] and 2.96 [95% CI: 1.52-5.77]) and friends (ARRR=5.78 [95% CI: 3.60-9.30], 4.98 [95% CI: 3.22-7.72] and 6.61 [95% CI: 2.91-15.01]) who use HTPs. HTP use frequency was not associated with quit attempts, except for monthly HTP use predicting SQAs lasting ≥30 days (ARRR=2.12 [95% CI: 1.17-3.85]). Initiation of HTP use was not associated with changes in smoking frequency. Limiting analysis to those who intend to quit smoking also yielded null results. CONCLUSIONS: Among Mexican adult smokers, frequency of HTP use was mostly not associated with either cessation behaviors or changes in cigarette consumption, suggesting that HTPs have limited to no effectiveness for smoking cessation.
RESUMEN
Objective: To develop the Mexico Smoking and Vaping Model (Mexico SAVM) to estimate cigarette and electronic nicotine delivery systems (ENDS) prevalence and the public health impact of legalizing ENDS use. Methods: SAVM, a cohort-based discrete-time simulation model, compares two scenarios. The ENDS-Restricted Scenario estimates smoking prevalence and associated mortality outcomes under the current policy of an ENDS ban, using Mexico-specific population projections, death rates, life expectancy, and smoking and e-cigarette prevalence. The ENDS-Unrestricted Scenario projects smoking and vaping prevalence under a hypothetical scenario where ENDS use is allowed. The impact of legalizing ENDS use is estimated as the difference in smoking- and vaping-attributable deaths (SVADs) and life-years lost (LYLs) between the ENDS-Restricted and Unrestricted scenarios. Results: Compared to a national ENDS ban, The Mexico SAVM projects that legalizing ENDS use could decrease smoking prevalence by 40.1% in males and 30.9% in females by 2049 compared to continuing the national ENDS ban. This reduction in prevalence would save 2.9 (2.5 males and 0.4 females) million life-years and avert almost 106 (91.0 males and 15.5 females) thousand deaths between 2025 and 2049. Public health gains decline by 43% to 59,748 SVADs averted when the switching rate is reduced by half and by 24.3% (92,806 SVADs averted) with a 25% ENDS risk level from that of cigarettes but increased by 24.3% (121,375 SVADs averted) with the 5% ENDS risk. Conclusions: Mexico SAVM suggests that greater access to ENDS and a more permissive ENDS regulation, simultaneous with strong cigarette policies, would reduce smoking prevalence and decrease smoking-related mortality. The unanticipated effects of an ENDS ban merit closer scrutiny, with further consideration of how specific ENDS restrictions may maximize public health benefits.
RESUMEN
INTRODUCTION: This study aimed to assess whether two established psychosocial predictors of smoking abstinence, nicotine dependence and time-discounting, also apply to a population of predominantly cigarette light smokers, which is the dominant pattern of smoking in countries like Mexico. Relatively infrequent smoking is increasingly prevalent, yet still harmful, making it important to understand the predictors of cessation in this population. AIMS AND METHODS: Mexican adult smokers recruited from an online consumer panel were surveyed every 4 months between November 2018 and July 2020. We considered respondents who reported a quit attempt in between surveys (nâ =â 1288). Dependence was measured with a 10-item version of the Wisconsin Inventory of Smoking Dependence Motives (WISDM). Time-discounting was assessed with five branching questions about hypothetical reward scenarios. Logistic models regressed sustained quit attempts (≥30 days of abstinence) at time tâ +â 1 on study variables at time t. RESULTS: We found strong interitem reliability (α = 0.92) and intraindividual consistency of our brief WISDM (ρ = 0.68), but moderate intraindividual consistency of the time-discounting measure (ρ = 0.48). Forty-eight percent of the sample reported sustained quit attempts, and 79% were non-daily or light daily smokers (≤5 cigarettes per day). Smokers with higher WISDM-10 had lower odds of sustained quitting and this result remained when controlling for smoking frequency and the Heaviness of Smoking Index (adjusted odds ratio [AOR]â =â 0.768). Time-discounting was unassociated with sustained quitting. CONCLUSIONS: Our findings suggest that a brief, 10-item multidimensional measure of dependence is useful for predicting sustained quitting in a context of relatively light smoking; time-discounting appears less relevant, although our results are not conclusive because of the low test-retest reliability of our measure. IMPLICATIONS: Given the increase in non-daily and light daily cigarette smoking in many countries, including in Mexico, and the health risks this still poses, it is important to understand the predictors of cessation among relatively light smokers. The WISDM-10 multidimensional measure seems to be a good instrument to assess dependence and predict successful quitting in this population, and possibly more appropriate than physical dependence measures. As such, it could help design and target more suitable cessation treatments for non-daily and daily light cigarette smokers. While this study did not find time-discounting to be a relevant predictor of smoking abstinence, future studies should explore other measures.

Background: Hypertension and type 2 diabetes (T2D) are the most prevalent noncommunicable diseases in Mexico and worldwide. According to international practice management guidelines, the principal chronic management therapy is daily oral medication. Aim: We aim to describe the trends of antihypertensive, antidiabetic, and nonsteroidal anti-inflammatory (NSAID) drugs use among the Mexican adult population from 2004-2018. Methods: We analyzed data from the Health Workers Cohort Study (HWCS) for males and females aged >18 years. We calculated the prevalence of chronic diseases and utilization for every kind of antihypertensive, antidiabetic, and NSAIDs (measured by self-reported utilization) at baseline and two follow-ups (2004, 2010, and 2017). Trends were analyzed using Fisher's exact test. Results: Hypertension prevalence increased from 19.8 to 30.3%, higher than T2D prevalence from 7.0 to 12.8% through fourteen years of follow-up. Like the self-reported dual therapy, the proportion of patients using beta-blockers and angiotensin II receptor blockers increased. Regarding T2D, the prevalence of metformin utilization increased to 83.9%. The utilization of common NSAIDs, mainly for muscular pain, remained around 13 to 16%. Conclusions: Our findings showed a changing prevalence of drug utilization for hypertension and T2D between 2004 and 2018 and consistent use of NSAIDs in the adult Mexican population.
RESUMEN
The objective of this study was to evaluate the effectiveness of digital and traditional methods and strategies in the recruitment of Mexican individuals who smoke into a cessation study. Recruitment method refers in general to either digital or traditional recruitment. Recruitment strategies refer to the particular recruitment type utilized within each recruitment method. Traditional recruitment strategies included radio interviews, word of mouth, newspaper advertisement, posters/banners placed in primary healthcare clinics, and medical referrals. Digital recruitment strategies involved emails and study advertisements through social media (i.e., Facebook, Instagram and Twitter) and website. In a 4-month period, 100 Mexican individuals who smoke were successfully enrolled into a smoking cessation study. The majority of participants were enrolled via traditional recruitment strategies (86%) compared to the digital recruitment strategies (14%). Individuals screened in the digital method were more likely to be eligible to participate in the study, compared to the traditional method. Similarly, in comparison to the traditional method, individuals in the digital method were more likely to enroll in the study. However, these differences were not statistically significant. Both traditional and digital strategies made important contributions to the overall recruitment effort.

Abstract Objective: To perform a cost-effectiveness analysis (CEA) of two programs designed to increase the physical activity (PA) of hypertensive patients at the primary-care level: the first based on the Reference Scheme (RS) and the second on the Brief Counseling (BC) approach, both within the context of a Mexican social security institution: The Mexican Social Security Institute (IMSS). Material and Methods: A CEA was undertaken from the perspective of service providers, with a time horizon of 24 weeks. Effectiveness was estimated in two ways: an increase in the minutes of moderate-vigorous PA (MVPA) and the percentage of patients engaging in ≥150 weekly minutes of MVPA at the end of each program. Results: RS patients performed 8.1 additional minutes of PA (week 24 = 169.29 minutes; week zero = 161.23). RS program proved approximately 1% more expensive and more effective and had an incremental cost-effectiveness ratio of 299 US$ per increased percentage point of patients engaging in ≥150 weekly minutes of MVPA at the end of each program. The sensitivity analysis yielded an up to 56% probability that the RS program would be cost- effective in increasing the percentage of patients performing the targeted MVPA per week. Conclusions: Our results indicate that in the context of a social security institution such as the IMSS, it is not cost-effective to implement an RS-based program to increase physical activity levels in hypertensive patients. Further evidence is required on the cost-effectiveness of both programs regarding other effectiveness measures such as biochemical and physical condition parameters, as well as to other types of population, given that this was the first CEA of PA programs in Mexico.
Resumen Objetivo: Realizar un análisis de costo-efectividad (ACE) de dos programas diseñados para incrementar la actividad física (AF) de pacientes hipertensos: el primero basado en el Esquema de Referencia (ER) y el segundo con un enfoque de Asesoramiento o Consejería Breve (CB), ambos en el contexto de primer nivel de atención en una institución de seguridad social de México: El Instituto Mexicano del Seguro Social (IMSS). Material y métodos: Se realizó un ACE desde la perspectiva de los proveedores de servicios, con un horizonte temporal de 24 semanas. La efectividad se midió con dos indicadores: aumento en los minutos de AF moderada-vigorosa (AFMV) y en el porcentaje de pacientes que participaron en ≥150 minutos de AFMV semanales al final de cada programa. Resultados: Los pacientes con ER realizaron 8.1 minutos adicionales de AF (semana 24 = 169.29 minutos; semana cero = 161.23). El programa ER demostró ser aproximadamente 1% más costoso y efectivo, y tuvo una relación costo-efectividad incremental de 299 dólares por cada punto porcentual de incremento de pacientes que cumplían con ≥150 minutos de MVPA semanales al final de cada programa. El análisis de sensibilidad arrojó una probabilidad de hasta 56% de que el programa ER fuera costo-efectivo para aumentar el porcentaje de pacientes que cumplen con las recomendaciones de AF semanales. Conclusiones: Nuestros resultados indican que en el contexto de una institución de seguridad social como el IMSS, no es costo-efectivo implementar un programa basado en ER para aumentar los niveles de actividad física en pacientes hipertensos.Se requiere mayor evidencia sobre la relación costo-efectividad de ambos programas con respecto a otras medidas de efectividad como parámetros bioquímicos y de condición física, así como a otro tipo de población, dado que este fue el primer ACE de programas de AF en México.
RESUMEN
Objectives: To evaluate the prevalence of exposure to Internet communications on and advertising of electronic cigarettes (e-cigarettes) and their association with perceptions of the social acceptability of e-cigarettes in Mexico. Methods: Data were analyzed from eight surveys (2018-2021) of an online sample of Mexican adult (> 18 years) smokers and dual users (of combustible and electronic cigarettes). Self-reported exposure to e-cigarette advertising across various marketing channels was assessed, as well as visits to e-cigarette websites. Logistic regression analysis was used to evaluate the association between perceptions of the social acceptability of e-cigarette use and level of advertising exposure and visits to e-cigarette websites. Results: The Internet and outside e-cigarette stores were where exposure to advertising most occurred, as reported by 47.4% and 46.8% of respondents, respectively. Respondents who noticed e-cigarette advertisements on the Internet (adjusted odds ratio (OR) 1.43, 95% confidence intervals (CI) 1.25, 1.63), outside e-cigarette stores (adjusted OR 1.31, 95% CI 1.14, 1.50), and in temporary outlets (adjusted OR 1.16, 95% CI 1.01, 1.34), and those who visited e-cigarette websites (adjusted OR 1.48, 95% CI 1.25, 1.76) were more likely to perceive e-cigarettes as socially acceptable. Noticing advertisements across more channels was also associated with higher perceived social acceptability of e-cigarette use. Conclusions: Being exposed to e-cigarette marketing, either online or through traditional marketing channels, is associated with perceived social acceptability of e-cigarette use, as is contact with provaping sites. Regulatory options to avoid the proliferation of promotional websites disguised as opinion or user sites need to be considered.
RESUMEN
This study examined transitions in tobacco products use among Mexican smokers and dual users. Data were analyzed from exclusive smokers (n = 2,946) and dual users (n = 1,643) recruited from an online consumer research panel and surveyed every-four months from November 2018 to April 2021. For exclusive smokers, estimated transitions were (time "t + 1" four months after prior survey): a) remain as exclusive smokers; b) dual use; c) exclusive e-cigarette use or quit both products. Among dual users, transitions analyzed were: a) remain as dual user; b) exclusive smoker; c) exclusive e-cigarette user or quit both products. Multinomial models regressed transitions at "t + 1" on time "t" for control variables. Most exclusive smokers (81%) remained as such, 12.6% transitioned to dual use, 2.3% to exclusive e-cigarette use, and 4% quitted both products. Exclusive smokers were more likely to transition to dual use if they recently attempted to quit (AOR = 1.45) or had partners/family or friends who used e-cigarettes (AOR = 2.47 & 2.56 respectively). Most dual users (74.8%) remained as dual users, 20.4% transitioned to exclusive smoking, 1.6% transitioned to exclusive e-cigarette use, and 3.2% quitted both products. Dual users were more likely to transition to exclusive smoking if they had lower educational attainment, recently attempted to quit e-cigarettes (AOR = 1.70). Having friends who use e-cigarettes (AOR = 0.29) and higher smoking dependence (AOR = 0.55) were associated with a lower likelihood of quitting. Recent quit attempts and e-cigarette use among close social network members may explain the short-term transitions, though longer follow-up is needed to assess sustained smoking cessation.
RESUMEN
BACKGROUND: A few prospective studies have investigated the potential association of soft drink and non-caloric soft drink intake with high blood pressure using methods that adequately consider changes in intake over time and hypertensive status at baseline. OBJECTIVE: To prospectively examine the association of soft drink and non-caloric soft drink intake with systolic and diastolic blood pressure in a sample of Mexican adults, overall and by hypertension status. METHODS: We used data from the Health Workers Cohort Study spanning from 2004 to 2018 (n = 1,324 adults). Soft drink and non-caloric soft drink intake were assessed with a semiquantitative food frequency questionnaire. We fit multivariable-adjusted fixed-effects models to test the association of soft drink and non-caloric soft drink intake with systolic and diastolic blood pressure. The models were adjusted for potential confounders and considering the potential modifying effect of hypertension status at baseline. RESULTS: A one-serving increase in soft drink intake was associated with a 2.08 mm Hg (95% CI: 0.21, 3.94) increase in systolic blood pressure and 2.09 mm Hg (95% CI: 0.81, 3.36) increase in diastolic blood pressure over ten years. A stronger association between soft drink intake and diastolic pressure was observed among participants with versus without hypertension at baseline. We found no association between non-caloric soft drink intake and blood pressure. CONCLUSIONS: Our findings support the hypothesis that soft drink intake increases blood pressure. While further studies should be conducted to confirm our findings, food policies and recommendations to limit soft drink intake are likely to help reduce blood pressure at the population level. We probably did not find an association between non-caloric soft drink intake and blood pressure because of the low consumption of this type of beverage in the cohort. More studies will be needed to understand the potential effect of non-caloric beverages on blood pressure.

INTRODUCTION: Flavor capsule cigarettes are rapidly gaining global market share, particularly in Latin America; however, little is known about consumer profiles and perceptions since the diffusion of this product innovation has become more widespread. AIMS AND METHODS: This paper compares profiles and perceptions of smokers who prefer flavor capsule cigarettes and those who do not in Mexico. We analyzed data from six online surveys of adult Mexican smokers (n = 4488) from 2018-2020. Participants identified their preferred brand variety characteristics (no capsule; one capsule; two capsules), and reported perceptions of their brand varieties' flavor, smoothness, harmfulness, and whether they smoke to control their appetite. Separate multinomial logistic models regressed preferred cigarette type on sociodemographic and smoking-related variables, as well as perceived benefits on preferred cigarette type, adjusting for covariates. RESULTS: Most participants preferred capsule cigarettes (single capsule = 47.5%; double capsule = 12.9%). Flavor capsule users reported that their preferred varieties mostly tasted like menthol/mint (59% of single capsule users and 23% of double capsule users), cucumber (12% and 27%, respectively) or berries (10% and 22%, respectively). Females were more likely than males to prefer either single or double capsule cigarettes (AOR = 2.26 and 2.01, respectively). Preference for flavor capsules was also higher among younger smokers, e-cigarette users, those who smoke less frequently, and those who recently tried or plan to quit. Smokers who preferred capsules were more likely than non-capsule smokers to perceive their cigarettes as smoother, less harmful, and to smoke to control their appetite. CONCLUSIONS: The high prevalence of capsule use and widespread perceptions of the benefits of capsules over traditional cigarettes may help explain why tobacco control policies have not reduced smoking prevalence in Mexico. IMPLICATIONS: Flavor capsules are rapidly growing in popularity in many countries around the world, including Mexico. This study found that more Mexican adult smokers prefer brand varieties with capsules (60%) than without capsules (40%), that flavor capsule use strongly correlates with menthol cigarette use, and that perceived flavors of capsules range widely. Flavor capsule smokers have more positive smoking expectancies (eg, lower risk perceptions, dietary control) than noncapsule smokers. Capsules appeal particularly to women, young adults, less frequent smokers, and those who recently tried to quit. Policies should consider banning flavors in cigarettes, including capsules and other filter innovations.

BACKGROUND: Little is known about the use of novel heated tobacco products (HTPs) in low- and middle-income countries. We examined among smokers in Mexico the prevalence and correlates of HTP use, as well as reasons for using HTPs. METHODS: We analyzed data from five surveys (November 2019-March 2021) of an open cohort of adult smokers (n = 6500), including an oversample of those who also use e-cigarettes. Mixed-effects multinomial logistic models were used to estimate associations between study variables and current HTP use or prior HTP trial relative to never trying HTPs. RESULTS: The weighted prevalence of current HTP use was 1.1%. Independent correlates of current HTP use included smoking frequency, intention to quit, e-cigarette use, having partners/family-members who use e-cigarettes, friends who use HTPs, and exposure to HTP information inside/outside tobacco shops. Having partners/family members who smoke and not knowing about the harm of HTPs relative to cigarettes were associated with lower likelihood of current HTP use. Having tried HTPs was more likely among light daily smokers, those with family who use HTPs and exposure to HTP information outside shops and on newspapers/magazines. Among current users, the top reasons for using HTPs were greater social acceptability (50.6%) and lower perceived harm (34.9%) relative to cigarettes. CONCLUSIONS: Uptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use. Further research is needed to determine if HTPs use promotes or impedes smoking cessation, given current HTP users are also likely to use various nicotine products.

Twenty years after its launch, the most ambitious preventive program implemented at the institutional level in Mexico called PREVENIMSS focuses on new challenges and moves towards relaunching. This paper reviews the foundations and design of PREVENIMSS and its evolution throughout these two decades. The PREVENIMS coverage assessment through national surveys set a relevant precedent in evaluating programs at the Mexican Institute of Social Security. PREVENIMSS has shown progress in preventing vaccine-preventable diseases. However, given the current epidemiological profile, there is still a need to provide more effective primary and secondary prevention of chronic noncommunicable diseases. New digital resources and orientation of PREVENIMSS towards a more comprehensive approach that contemplates secondary prevention and rehabilitation can help to face the growing challenges that the program still faces.
A 20 años de su lanzamiento, el programa preventivo más ambicioso implementado a nivel institucional en México llamado PREVENIMSS se enfoca en nuevos desafíos y avanza hacia el relanzamiento. Este artículo hace un breve recorrido de sus fundamentos, diseño y evolución a lo largo de estas dos décadas. La estimación de las coberturas de PREVENIMSS a través de encuestas nacionales también marcó un precedente en la evaluación de programas en el Instituto Mexicano del Seguro Social. PREVENIMSS ha mostrado avances en prevención de enfermedades prevenibles por vacunación, pero aún existe la necesidad de brindar prevención primaria y secundaria más efectivos de las enfermedades crónicas no transmisibles ante el perfil epidemiológico actual. Nuevos recursos digitales y la orientación hacia un enfoque más integral que contemple la prevención secundaria y la rehabilitación pueden ayudar a enfrentar los crecientes desafíos que aún enfrenta el programa.

OBJECTIVE: To systematically review published articles reporting the use of smoking cessation mobile health (mHealth) interventions in Latin America. METHODS: Five different databases were searched from database inception to 2020. Criteria: (1) the research was a smoking cessation randomized controlled trial (RCT), quasi-experimental research, or single-arm study; (2) the intervention used at least one type of mHealth intervention; (3) the research was conducted in Latin American; and (4) the research reported the cessation rate. RESULTS: Of the seven selected studies, four were conducted in Brazil, two in Mexico, and one in Peru. Only one study was an adequately powered RCT. Interventions relied on text messages (n = 3), web-based tools (n = 2), and telephone calls (n = 3). Some studies (n = 4) provided pharmacotherapy support. Smoking cessation outcomes included self-reported (n = 5) and biochemically verified (n = 2) abstinence. Follow-ups were conducted at Month 6 (n = 2), Week 12 (n = 4), and Day 30 (n = 1). Cessation rates varied from 9.4% at Week 12 to 55.5% at Day 30. CONCLUSION: Despite the promising cessation rates of mHealth interventions in Brazil, Mexico, and Peru, there is a need to rigorously evaluate these interventions in different Latin American countries with RCTs that are long-term, adequately powered, and use biochemical verification of cessation.

ABSTRACT Objectives. To evaluate the prevalence of exposure to Internet communications on and advertising of electronic cigarettes (e-cigarettes) and their association with perceptions of the social acceptability of e-cigarettes in Mexico. Methods. Data were analyzed from eight surveys (2018-2021) of an online sample of Mexican adult (> 18 years) smokers and dual users (of combustible and electronic cigarettes). Self-reported exposure to e-cigarette advertising across various marketing channels was assessed, as well as visits to e-cigarette websites. Logistic regression analysis was used to evaluate the association between perceptions of the social acceptability of e-cigarette use and level of advertising exposure and visits to e-cigarette websites. Results. The Internet and outside e-cigarette stores were where exposure to advertising most occurred, as reported by 47.4% and 46.8% of respondents, respectively. Respondents who noticed e-cigarette advertisements on the Internet (adjusted odds ratio (OR) 1.43, 95% confidence intervals (CI) 1.25, 1.63), outside e-cigarette stores (adjusted OR 1.31, 95% CI 1.14, 1.50), and in temporary outlets (adjusted OR 1.16, 95% CI 1.01, 1.34), and those who visited e-cigarette websites (adjusted OR 1.48, 95% CI 1.25, 1.76) were more likely to perceive e-cigarettes as socially acceptable. Noticing advertisements across more channels was also associated with higher perceived social acceptability of e-cigarette use. Conclusions. Being exposed to e-cigarette marketing, either online or through traditional marketing channels, is associated with perceived social acceptability of e-cigarette use, as is contact with provaping sites. Regulatory options to avoid the proliferation of promotional websites disguised as opinion or user sites need to be considered.
RESUMEN Objetivos. Evaluar la prevalencia de la exposición a las comunicaciones por Internet y la publicidad de los cigarros electrónicos (e-cigarettes), así como su asociación con las percepciones sobre la aceptabilidad social de los cigarrillos electrónicos en México. Métodos. Se analizaron los datos de ocho encuestas (2018-2021) de una muestra en línea de adultos mexicanos (mayores de 18 años) fumadores y consumidores dobles (cigarrillos combustibles y cigarrillos electrónicos). Se evaluaron la exposición —referida por los propios encuestados— a la publicidad de cigarrillos electrónicos en varios canales de comercialización y las visitas a sitios web de cigarrillos electrónicos. Se realizó un análisis de regresión logística para evaluar la relación entre la percepción de aceptabilidad social del consumo de cigarrillos electrónicos, por una parte, y el nivel de exposición publicitaria y las visitas a sitios web de cigarrillos electrónicos, por la otra. Resultados. La mayor exposición a la publicidad se dio en las tiendas virtuales y físicas donde se venden cigarrillos electrónicos, según lo notificado por 47,4% y 46,8% de los encuestados, respectivamente. Los encuestados que observaron anuncios de cigarrillos electrónicos en Internet (razón de probabilidades ajustada [OR ajustada] 1,43; intervalos de confianza [IC] del 95 %: 1,25; 1,63), en tiendas físicas de cigarrillos electrónicos (OR ajustada 1,31; IC del 95 %: 1,14; 1,50) y en puntos de venta temporales (OR ajustada 1,16; IC del 95 %: 1,01; 1,34), y los que visitaron sitios web de cigarrillos electrónicos (OR ajustada 1,48; IC del 95 %: 1,25; 1,76) fueron más propensos a percibir los cigarrillos electrónicos como socialmente aceptables. Asimismo, se asoció el hecho de observar anuncios en más canales con la percepción de una mayor aceptabilidad social del consumo de cigarrillos electrónicos. Conclusiones. La exposición a la publicidad de los cigarrillos electrónicos, ya sea en línea o por los canales tradicionales, así como el contacto con sitios web que promueven el vapeo, se relaciona con la percepción acerca de la aceptabilidad social del consumo de cigarrillos electrónicos. Deberían considerarse alternativas regulatorias para evitar la proliferación de sitios web promocionales disfrazados de sitios de opinión o de usuarios.
RESUMO Objetivos. Avaliar a prevalência da exposição a comunicações e propagandas sobre cigarros eletrônicos na internet e sua associação com percepções de aceitação social dos cigarros eletrônicos no México. Métodos. Foram analisados dados de oito pesquisas (2018 a 2021) de uma amostra on-line de adultos mexicanos (maiores de 18 anos) fumantes e usuários duais (de cigarros combustíveis e eletrônicos). Avaliou-se a exposição autorrelatada à propaganda de cigarros eletrônicos em diversos canais de marketing, além de visitas a sites de cigarros eletrônicos. Foi utilizada uma análise de regressão logística para avaliar a associação entre percepções de aceitação social do uso de cigarros eletrônicos e o nível de exposição a propagandas e visitas a sites de cigarros eletrônicos. Resultados. A maior exposição a propaganda ocorreu na internet e no exterior de tabacarias que vendem cigarros eletrônicos, conforme relatado por 47,4% e 46,8% dos respondentes, respectivamente. Os respondentes que haviam notado propagandas de cigarros eletrônicos na internet (razão de chances [RC] ajustada: 1,43; intervalo de confiança [IC] de 95%: 1,25-1,63), no exterior de tabacarias que vendem cigarros eletrônicos (RC ajustada: 1,31; IC de 95%: 1,14-1,50) e em pontos temporários de venda (RC ajustada: 1,16; IC de 95%: 1,01-1,34), e os respondentes que visitavam sites de cigarros eletrônicos (RC ajustada: 1,48; IC de 95%: 1,25-1,76) eram mais propensos a achar que os cigarros eletrônicos eram socialmente aceitáveis. A observação de propaganda em um maior número de canais também estava associada à percepção de maior aceitação social do uso de cigarros eletrônicos. Conclusões. A exposição ao marketing de cigarros eletrônicos, seja on-line ou por meio de canais tradicionais de marketing, está associada à percepção de aceitação social do uso de cigarros eletrônicos, assim como o contato com sites pró-vaping. Devem-se cogitar opções regulatórias para evitar a proliferação de sites promocionais disfarçados de sites de opinião ou de usuários.
RESUMEN
INTRODUCTION: Approximately 25% of the adult population worldwide and 49.8% of Mexican adults have metabolic syndrome. Metabolic syndrome is the result of unhealthy dietary and sleeping patterns, sedentary behaviors, and physical inactivity. The objective of our study was to evaluate the association between sedentary behaviors as screen-based sedentary time (SBST) and each component of metabolic syndrome among adults who participated in the Mexico National Survey of Health and Nutrition Mid-way 2016. METHODS: We analyzed sociodemographic, clinical, and physical activity data from 3,166 adults aged 20 years or older. The International Physical Activity Questionnaire was used to evaluate sedentary behavior. SBST was obtained by counting minutes per week spent watching television, playing video games, and interacting with computers and smartphones. We used Poisson regression to estimate the prevalence ratio of time in front of screens as a continuous variable and its association with metabolic syndrome. RESULTS: The mean (SD) hours per day of SBST in men was 3.6 (0.4) and in women was 2.8 (0.2). The prevalence of metabolic syndrome was 59.6%. In men, the risk for metabolic syndrome increased 4% (P < .05) for each hour of SBST. Similarly, for each hour of SBST, the risk of abdominal obesity increased by 4% (P < .01). In women, we observed that the risk of hypertension or high-density lipoprotein cholesterol deficiency increased for each hour of SBST, and the risk of abdominal obesity increased for each hour of SBST in those who were inactive. CONCLUSION: Sedentary behavior based on screen time is associated with metabolic syndrome and its components among Mexicans, depending on hours of sleep. Current public health policies should consider strategies for reducing SBST.

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 (ß = 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 (ß = 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.
