RESUMEN

OBJECTIVES: The study aimed to evaluate the cost-effectiveness of the Pare de Fumar Conosco software compared with the standard of care adopted in Brazil for the treatment of smoking cessation. METHODS: In the cohort of smokers with multiple chronic conditions, we developed an decision tree model for the benefit measures of smoking cessation. We adopted the perspectives of the Brazilian Unified Health System and the service provider. Resources and costs were measured by primary and secondary sources and effectiveness by a randomized clinical trial. The incremental cost-effectiveness ratio (ICER) was calculated, followed by deterministic and probabilistic sensitivity analyses and deterministic and probabilistic sensitivity analyses. No willingness to pay threshold was adopted. RESULTS: The software had a lower cost and greater effectiveness than its comparator. The ICER was dominant in all of the benefits examined (-R$2 585 178.29 to -R$325 001.20). The cost of the standard of care followed by that of the electronic tool affected the ICER of the benefit measures. In all probabilistic analyses, the software was superior to the standard of care (53.6%-82.5%). CONCLUSION: The Pare de Fumar Conosco software is a technology that results in cost savings in treating smoking cessation.

RESUMEN

Objective: To assess the prevalence of current cigarette smoking among transgender women in Argentina, and to examine the unique associations of current cigarette smoking with demographic and psychosocial factors. Methods: This study is a secondary data analysis of the TransCITAR - a prospective cohort study of transgender individuals living in Buenos Aires, Argentina - baseline data. The baseline survey collected information on sociodemographic characteristics, perceived health status, depressive symptoms, suicide attempts, current cigarette smoking, alcohol use disorder, and substance use. Participants were also asked about lifetime experiences of physical and sexual violence perpetrated by partners, clients and/or the police, and experiences of gender identity stigma in the past year from healthcare workers and the police. Lastly, participants were asked if they had ever been arrested. Fisher's exact test was used to compare proportions in categorical variables and student t-test was used for continuous variables. Significant associations with current cigarette smoking were tested in a logistic regression model adjusted for all significant associations. Results: A total of 41.7% of participants (n = 393) reported current cigarette smoking. Compared to their non-smoking counterparts, participants who reported current cigarette smoking (1) had completed less education, (2) were more likely to be born in Argentina, (3) more likely to had migrated to Buenos Aires from other parts of the country, (4) more likely to report a history of sex work, (5) more likely to perceive their health as excellent, (6) more likely to screen positive for hazardous alcohol drinking, (7) more likely to report any substance and cocaine use in the past year, (8) more likely to experience gender identity stigma from the police in the past year, and (9) more likely to being arrested in their lifetime (all p's < 0.05). After controlling for all significant associations, education level of less than high school (AOR = 1.79, 95% CI 1.02-2.12), hazardous drinking (AOR = 2.65, 95% CI 1.30-5.37), and any substance use in the last year (AOR = 2.14, 95% CI 1.16-3.94) were positively and independently associated with current cigarette smoking. Conclusion: Among transgender women in Argentina, current cigarette smoking was more than double the rate for cisgender women. Current cigarette smoking was associated with education, hazardous drinking, and any drug use. These results will inform future smoking cessation interventions among transgender women in Argentina.

RESUMEN

In the last decade, we have seen a substantial increase in the development and use of mobile technology to improve diet and healthy eating behaviors. OBJECTIVE: To describe the characteristics of nutrition and diet apps before and after the COVID-19 pandemic available in Brazil. METHODS: Nutrition and diet apps were identified using the official Apple and Google stores. The search occurred in January 2020 and May 2022 in Brazil. We extracted the nutritional content and standard indicators (e.g., being developed before or after 2020, number of languages, target population, investment, prices, seller, number of reviews and downloads, consumer rating). RESULTS: 280 apps were launched before and 411 during the COVID-19 period. Most apps were available in at least ten languages (96.6%), with no indication of age (95.6%) or partial or full cost (59%). As for the contents, 18.9% addressed personal diet suggestions; 73.4%, nutritional education; 48.8%, revenues; 35.9%, physical activity with a nutritional guide; 2.3%, nutritional recommendation for eating out; 23.9%, grocery shopping with a scan code; 32.4%, food diary; 18.9%, water intake; and 4.6%, nutrition/diseases. The data show an evolution that may have been boosted by the pandemic and that reveals a trend towards the development of apps with educational content. CONCLUSION: During the pandemic, there was a positive qualitative and quantitative movement in e-health regarding the promotion of education.

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.

RESUMEN

There is an underutilization of smoking cessation treatment among patients with chronic conditions, which indicates a need for new strategies to engage them. Web-based smoking cessation decision-making tools can be beneficial. This study assessed the effectiveness of the Pare de Fumar Conosco software at increasing engagement to smoking cessation counseling groups among Brazilian smokers with chronic conditions. Clinical trial participants were randomized to Pare de Fumar Conosco or standard of care. Engagement in the smoking cessation counseling group was the primary outcome. Secondary outcomes included motivation level, cessation rate, completion, and treatment adherence. The t-tests and Chi-square analyzed baseline differences between groups and the Poisson models, the effects of the intervention. Engagement rates were higher in the Pare de Fumar Conosco (IR=2.22; 95% CI: 1.06 - 4.63) concerning the standard of care. Pare de Fumar Conosco group was more adherent to treatment over time (6.4% versus 4.2% in the final week). Cessation rate was 26.3% in standard care and 23.1% in Pare de Fumar Conosco. Both interventions maintained significant motivation levels to quit smoking. The Pare de Fumar Conosco intervention effectively increases the engagement in the smoking cessation counseling groups. There is a need to improve the smoking cessation rate.

RESUMEN

OBJECTIVE: To assess the clinical practice, barriers, and facilitators in promoting smoking cessation in primary healthcare clinics in Mexico City. MATERIALS AND METHODS: A mixed method design was used. Surveys (n = 70) and semi-structured interviews (n = 9) were conducted with health personnel involved in smoking cessation clinics. RESULTS: Quantitative data revealed that physicians were more likely than nurses to 1) ask patients if they smoke (57.9% vs 34.5%, p = .057), 2) ask patients if they are interested in quitting smoking (65.7% vs 26.9%, p = .003), 3) provide advice to quit smoking (54.3% vs 29.2%, p = .056), and 4) assess whether pharmacotherapy is needed (21.9% vs 10%, p = .285). Qualitative data showed that nurses were more likely than physicians to report lack of resources to refer patients to smoking cessation services, lack of pharmacotherapy availability, and lack of provider training in smoking cessation. Reported barriers include lack of motivation among patients, lack of time for assessment, long appointment wait times, and lack of training. Reported facilitators include existence of smoking cessation programmes and pharmacotherapy at no cost to the patient, and having a multidisciplinary team. CONCLUSIONS: Due to numerous barriers, smoking cessation interventions are partially implemented in primary care clinics in Mexico City. A restructuring of services is necessary, and nurses should be given a more prominent role.

RESUMEN

Previous studies have identified variants in genes encoding proteins associated with the degree of addiction, smoking onset, and cessation. We aimed to describe thirty-one single nucleotide polymorphisms (SNPs) in seven candidate genomic regions spanning six genes associated with tobacco-smoking in a cross-sectional study from two different interventions for quitting smoking: (1) thirty-eight smokers were recruited via multimedia to participate in e-Decídete! program (e-Dec) and (2) ninety-four attended an institutional smoking cessation program on-site. SNPs genotyping was done by real-time PCR using TaqMan probes. The analysis of alleles and genotypes was carried out using the EpiInfo v7. on-site subjects had more years smoking and tobacco index than e-Dec smokers (p < 0.05, both); in CYP2A6 we found differences in the rs28399433 (p < 0.01), the e-Dec group had a higher frequency of TT genotype (0.78 vs. 0.35), and TG genotype frequency was higher in the on-site group (0.63 vs. 0.18), same as GG genotype (0.03 vs. 0.02). Moreover, three SNPs in NRXN1, two in CHRNA3, and two in CHRNA5 had differences in genotype frequencies (p < 0.01). Cigarettes per day were different (p < 0.05) in the metabolizer classification by CYP2A6 alleles. In conclusion, subjects attending a mobile smoking cessation intervention smoked fewer cigarettes per day, by fewer years, and by fewer cumulative pack-years. There were differences in the genotype frequencies of SNPs in genes related to nicotine metabolism and nicotine dependence. Slow metabolizers smoked more cigarettes per day than intermediate and normal metabolizers.

RESUMEN

BACKGROUND: While overall trends in tobacco use among men are declining, tobacco use continues to rise significantly among women in developing countries. This study aimed to explore the gender-related beliefs and attitudes about tobacco use and smoking cessation in Mexico, one of the top five Latin America countries with the highest prevalence of tobacco consumption. MATERIALS AND METHODS: This study was conducted using an explanatory qualitative methods design. Semi-structured interviews were conducted with 14 adults smokers (8 women & 6 men) who visited primary healthcare clinics in Mexico City. Two researchers independently coded the interviews and applied the final codes upon consensus. Inter-rater reliability was assessed for four groups of codewords (92% agreement), based on an ecological model on socio-cultural factors. FINDINGS: Initiation to smoking in women begins out of curiosity, and in men by imitation. Also, women start using tobacco at an older age compared to men. During maintenance of smoking, women report experiencing loneliness and anxiety about multiple responsibilities, e.g. women reveal that they feel guilty when they smoke due to their maternal role as caregivers. Additionally, some women report that smoking is a symbol of freedom, recalling the media messages associated with promoting tobacco products. Among men, the results show that they smoke for pleasure and to socialize, and consider that women smoke to imitate men and feel powerful. Regarding cessation, women are ambivalent about quitting smoking or not, and men mention not needing professional support. For organizational barriers, women mention the cost of treatment and men, the distance to clinics. CONCLUSION: Smoking cessation interventions should be proposed from an approach that involves changes in social norms, seeking a more equitable relationship between men and women. Therefore, there must be broad engagement from different sectors and not just at the health sector level.

RESUMEN

The purpose of this pilot study was to assess the feasibility and acceptability of a mobile smoking cessation intervention in Puerto Rico. This was a single-arm pilot study with 26 smokers in Puerto Rico who were enrolled in Decídetexto, a mobile smoking cessation intervention. Decídetexto incorporates three integrated components: (1) a tablet-based software that collects smoking-related information to develop an individualized quit plan, (2) a 24-week text messaging counseling program with interactive capabilities, and (3) pharmacotherapy support. Outcome measures included self-reported 7-day point prevalence abstinence at Months 3 and 6, pharmacotherapy adherence, satisfaction with the intervention, and changes in self-efficacy. The average age of the participants was 46.8 years (SD 12.7), half of them (53.8%) were female. Most participants (92.3%) smoked daily and half of them (53.8%) used menthol cigarettes. All participants requested nicotine patches at baseline. However, only 13.0% of participants used the patch >75% of days. At Month 3, 10 participants (38.4%) self-reported 7-day point prevalence abstinence (88.5% follow-up rate). At Month 6, 16 participants (61.5%) self-reported 7-day point prevalence abstinence (76.9% follow-up rate). Most participants (90%, 18/20) reported being satisfied/extremely satisfied with the intervention at Month 6. Self-efficacy mean scores significantly increased from 40.4 (SD 12.1) at baseline to 57.9 (SD 11.3) at Month 3 (p < 0.01). The study suggests that Decídetexto holds promise for further testing among Puerto Rican smokers.

RESUMEN

Objective: Assess the feasibility and acceptability of a culturally- and linguistically-adapted smoking cessation text messaging intervention for Latino smokers. Methods: Using a community-based strategy, 50 Latino smokers were recruited to participate in a smoking cessation pilot study. Participants received a 12-week text messaging intervention and were offered Nicotine Replacement Therapy (NRT) at no cost. We assessed biochemically verified abstinence at 12 weeks, text messaging interactivity with the program, NRT utilization, self-efficacy, therapeutic alliance, and satisfaction. Results: Participants were 44.8 years old on average (SD 9.80), and they were primarily male (66%) and had no health insurance (78%). Most of the participants were born in Mexico (82%) and were light smokers (1-10 CPD) (68%). All participants requested the first order of NRT, and 66% requested a refill. Participants sent an average of 39.7 text messages during the 12-week intervention (SD 82.70). At 12 weeks, 30% of participants were biochemically verified abstinent (88% follow-up rate) and working alliance mean value was 79.2 (SD 9.04). Self-efficacy mean score increased from 33.98 (SD 10.36) at baseline to 40.05 (SD 17.65) at follow-up (p = 0.04). The majority of participants (90.9%, 40/44) reported being very or extremely satisfied with the program. Conclusion: A culturally- and linguistically-adapted smoking cessation text messaging intervention for Latinos offers a promising strategy to increase the use of NRT, generated high satisfaction and frequent interactivity, significantly increased self-efficacy, produced high therapeutic alliance, and resulted in noteworthy cessation rates at the end of treatment. Additional testing as a formal randomized clinical trial is warranted.

RESUMEN

INSTRODUCTION: Nicotine Replacement Therapy (NRT) is an effective treatment for smoking cessation. However, medication usage and adherence remain a challenge that contributes to low smoking cessation rates. In Mexico, 8 in 10 smokers are interested in quitting. However, only 6% of Mexican smokers use medication for smoking cessation. The objective of this study is to assess the feasibility and acceptability of a mobile health (mHealth) intervention to increase usage and adherence of NRT in Mexico. METHODS: The study involves a secondary data analysis. Forty smokers were recruited to participate in a single-arm pilot study. Participants received an mHealth intervention that uses tablet-based decision support software to drive a 12-week text messaging smoking cessation program and pharmacotherapy support. The intervention allows two-way interactivity text messaging between participants and a tobacco treatment specialist. NRT was offered to participants in accordance with practice guidelines in Mexico. Outcome measures included utilization of NRT, text messaging interactivity with the program, and biochemically verified abstinence at 12 weeks. RESULTS: Thirty smokers met the criteria for use of NRT. Average age of participants was 38.1 years (SD=10.7), and they were primarily male (56.7%) with at least an undergraduate degree (60%). All participants requested NRT at baseline, and 60% requested a refill at week 4. During the 12-week intervention period, participants sent 620 messages to the program (mean=20.6, SD=18.34) of which 79 messages (12.7%) were related to NRT. Three themes were identified in the messages related to NRT: enthusiasm, instructions, and side effects. At 12 weeks, 40% of participants reported using NRT <75% of the days. Finally, 30% of participants (9/30) were biochemically verified abstinent using intention-to-treat analysis at 12 weeks. CONCLUSIONS: An mHealth intervention appears to offer a promising strategy to increase usage and adherence of NRT in Mexico. Additional testing as a formal randomized clinical trial appears warranted.

RESUMEN

OBJECTIVE: To assess the feasibility of Pare de fumar conosco, a web-based smoking cessation decision-making tool, among patients with chronic conditions in Brazil. METHODS: We recruited 85 Brazilian smokers in two clinical centres for chronic conditions to complete Pare de fumar conosco. Outcome measures included interest in using smoking cessation resources and self-reported 7-day point prevalence abstinence 12 weeks following the intervention. RESULTS: The average age of participants was 54.2 years old (SD=10.5) and 77.9% had not completed high school. All participants were daily smokers and the majority smoked ≥11 cigarettes per day (63.5%). Pre-post intervention interest in using pharmacotherapy and group counselling significantly increased (82.4% vs 22.4%, p≤0.0001; and 85.9% vs 21.2%, p≤0.0001, respectively). At 12 weeks, eight participants (9.4%) reported 7-day point prevalence abstinence using intention-to-treat analysis (35.2% follow-up rate). CONCLUSION: The Pare de fumar conosco smoking cessation web-based tool significantly increased interest in pharmacotherapy and behavioural counselling. Additional testing as a formal randomised clinical trial appears warranted.

RESUMEN

BACKGROUND: Guatemala lacks cancer prevention strategies and has low screening rates. OBJECTIVE: To assess the history of chronic conditions, risk factors, and cancer screening uptake among three Indigenous populations of Southwestern Guatemala. METHODS: We conducted a health needs assessment. RESULTS: The assessment was completed by 247 adults. Median age was 40 years old (IR: 28-59). Most participants were female (94.3%), of Mayan descent (95.8%), and did not have a primary health care provider (84.2%). Most have never been screened for colorectal (men=100.0%; women=98.8%), prostate (75.0%), breast (90.9%), or cervical (76.9%) cancer, and all have severe tooth decay. However, most participants reported healthy behaviors including being physically active (women=59.7%; men=92.9%), being nonsmokers (women=99.6%; men=78.6%), and not consuming alcohol (women=82.3%; men=46.7%). CONCLUSIONS: Although most participants reported healthy behaviors, there is a remarkable lack of access to cancer screening. An increase in cancer incidence is expected unless cancer prevention efforts are undertaken.

RESUMEN

BACKGROUND: Of the 14.3 million Mexicans who smoke, only a minority take advantage of evidence-based approaches to smoking cessation. Mobile health interventions have the potential to increase the reach of effective cessation interventions in Mexico. OBJECTIVE: This study aimed to assess the feasibility and acceptability of an innovative, personalized, and interactive smoking cessation mobile intervention developed for Mexican smokers. METHODS: We recruited 40 Mexican smokers to participate in Vive sin Tabaco... ¡Decídete!, a smoking cessation program that uses a tablet-based decision support software to drive a 12-week text messaging smoking cessation program and pharmacotherapy support. Outcome measures included participant text messaging interactivity with the program, participant satisfaction, and 12-week verified abstinence using urinary cotinine testing or exhaled carbon monoxide. RESULTS: Average age of the participants was 36 years (SD 10.7), and they were primarily male (65%, 26/40) with at least an undergraduate degree (62%, 25/40). Most participants (95%, 38/40) smoked daily and were interested in quitting in the next 7 days. As an indicator of participant interactivity, participants sent an average of 21 text messages during the 12-week intervention (SD 17.62). Of the 843 messages that participants sent to the program, only 96 messages (11.3%, 96/843) used keywords. At 12 weeks, 40% (16/40) of participants were biochemically verified (87%, 35/40, follow-up rate). The majority of participants (85%, 30/35) reported being very satisfied or extremely satisfied with the program. CONCLUSIONS: The Vive sin Tabaco... ¡Decídete! smoking cessation mobile intervention was accepted by participants, generated high satisfaction and high text messaging interactivity, and resulted in a noteworthy cessation rate at the end of treatment. This intervention is a promising strategy for smoking cessation in Mexico. Additional testing as a formal randomized clinical trial appears warranted.

RESUMEN

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in developed countries. Although cigarette smoking is the major risk factor, only 10-20% of smokers develop COPD. The extent of cigarette smoking (pack-years and smoking duration) accounts for only 15% of the variation in lung function, indicating that differences in susceptibility to COPD must exist. We provide an overview of the complexity of nicotine addiction and COPD, with special attention to the involvement of genetic factors. The following aspects are discussed in the present article: (1) epidemiology in Mexico and (2) a review of the published literature on genetic association studies using the National Center for Biotechnology Information database of the United States as a search tool. COPD is unique among complex genetic diseases where an environmental risk factor is known and the level of exposure can be documented with some precision. The high morbidity and mortality associated with COPD and its chronic and progressive nature has prompted the use of molecular genetic studies to identify susceptibility factors for the disease. Biomedical research has a remarkable set of tools to aid in the discovery of genes and polymorphisms. We present a review of the most relevant genetic associations in nicotine addiction and COPD.

RESUMEN

Introduction:While smoking remains one of the leading causes of death in Mexico, uptake of evidence-based cessation therapy remains low. Widespread use of mobile devices and internet in Mexico has created new avenues for providing access to cessation treatment.Methods:We assessed the feasibility and acceptability of "Vive Sin Tabaco… ¡Decídete!" (English: Live without Tobacco…. Decide!), a web-based, informed decision-making tool designed to help Mexican smokers develop a quit plan and take advantage of cessation resources. We invited 164 smokers in two primary care clinics. Measures included physical, situational, and psychological nicotine dependence, interest in using pharmacotherapy and counseling, smoking status at 3 months, and satisfaction with the program.Results:Most participants were light smokers and reported low-to-moderate nicotine dependence. Immediately after using ¡Vive Sin Tabaco… ¡Decídete!, the majority were interested in quitting, set a quit date, and reported interest in using pharmacotherapy and cessation counseling. Follow-up rate at 3 months was 81.5%; seven-day point prevalence abstinence was 19.1% using intention-to-treat analysis.Conclusion:Integration of e-Health tools in primary healthcare settings has the potential to improve knowledge about cessation treatments among smokers and integrate smoking cessation into routine of care.

RESUMEN

OBJECTIVE: To evaluate an e-Health tool designed to enhance smoking cessation in Mexico in primary healthcare. MATERIALS AND METHODS: Smokers 18 years of age and older were recruited in the waiting room of two primary healthcare clinics in Mexico City. Participants used an eHealth smoking cessation tool that included smoking-related assessments, education on pharmacotherapy, and motivational videos. A follow-up assessment was conducted at 12 weeks week on smoking status. Logistic regression models were performed to identify factors associated with smoking cessation or consumption reduction. RESULTS: A total of 132 smokers were enrolled in the study. At follow-up, 23.5% of participants self-reported smoking cessation. Among those who did not quit smoking, 65.0% decreased the number of cigarettes. Factors associated significantly with smoking cessation were: being a non-daily smoker, being interested in quitting smoking, having low level of physical dependence, and participating in cessation treatment. CONCLUSIONS: The e-Health tool produced a high rate of smoking cessation. Better outcomes are obtained when this tool is used with conventional cessation programs.
