Prevalência de tabagismo e morbimortalidade por câncer de pulmão nos estados brasileiros / Smoking prevalence and lung cancer morbimortality in Brazilian states / Prevalencia del tabaquismo y morbimortalidad por cáncer de pulmón en los estados brasileños

Introdução: O câncer de pulmão é uma doença grave, sendo a segunda maior causa de morte em todo o mundo, entretanto, em alguns países desenvolvidos, tornou-se já a primeira causa de morte. Cerca de 90% dos casos de neoplasia pulmonares são causados pela inalação da fumaça do cigarro. Objetivo: Correlacionar a prevalência de tabagismo e morbimortalidade por câncer de pulmão nos estados brasileiros, além de demonstrar a associação destes com sexo e faixa etária. Métodos: Estudo de caráter ecológico acerca da prevalência de tabagismo e morbimortalidade por câncer de pulmão nos estados brasileiros, nos períodos de 2013 e 2019, dividida por sexo e faixa etária. Foram utilizados bancos de coleta de dados como o Tabnet e Pesquisa Nacional de Saúde. Resultados: As maiores taxas de mortalidade e internações hospitalares foram do público masculino, em 2013, com taxa de 2,7 e 10, respectivamente, e em 2019 com 3,3 e 11,9, respectivamente. Ademais, a maior prevalência de tabagismo foi encontrada nos homens; entretanto seu índice tem caído, enquanto a quantidade de mulheres tabagistas tem aumentado. A Região Sul demonstrou maiores números de mortalidade em ambos os períodos estudados, com taxas de 4,9 e 5,8 por 100 mil habitantes, e morbidade hospitalar com 19,9 e 23,5 por 100 mil habitantes. Já a Região Norte se configurou com as menores prevalências: em 2013 apresentou taxa de óbito por câncer de pulmão de 1,0 e morbidade hospitalar de 3,5/100 mil habitantes, em 2019 apresentou taxa de mortalidade de 4,6 e internações de 1,6/100 mil habitantes. Os coeficientes de correlação de morbidade hospitalar e prevalência de tabagismo foram R2=0,0628, r=0,251 e p=0,042, enquanto os de mortalidade e prevalência de tabagismo foram R2=0,0337, r=0,183 e p=0,140. Conclusões: Na presente pesquisa, pode-se inferir que houve associação positiva na comparação entre taxa de morbidade hospitalar e prevalência de tabagismo; em contrapartida, não foi possível observar associação positiva na correlação da taxa de mortalidade por câncer de pulmão e prevalência de tabagismo.

Introduction: Lung cancer is a serious disease, being the second leading cause of death worldwide. Moreover, in some developed countries, it has already become the leading cause of death. About 90% of lung cancer cases are caused by cigarette smoking. Objective: To correlate the prevalence of smoking and lung cancer morbidity and mortality in Brazilian states, and to demonstrate their association with sex and age group as well. Methods: An ecological study on the prevalence of smoking and lung cancer morbidity and mortality in Brazilian states between 2013 and 2019, divided by sex and age group. The data collection databases Tabnet and National Health Survey were used. Results: The highest rates of mortality and hospital admissions were among men, in 2013 with a rate of 2.7 and 10, respectively, and in 2019 with 3.3 and 11.9, respectively. In addition, the highest prevalence of smoking was found in men, but this rate has fallen, while the number of women smokers has increased. The South region showed higher mortality rates in both periods studied, with rates of 4.9 and 5.8 per 100,000 inhabitants, and hospital morbidity with 19.9 and 23.5 per 100,000 inhabitants. The North region had the lowest prevalence, where in 2013, it had a death rate from lung cancer of 1.0 and hospital morbidity of 3.5/100 thousand inhabitants, and where in 2019, it had a mortality rate of 4.6 and hospitalizations of 1.6/100 thousand inhabitants. The correlation coefficients for hospital morbidity and smoking prevalence were R2=0.0628, r=0.251 and p=0.042, while for mortality and smoking prevalence, these were R2=0.0337, r=0.183 and p=0.140. Conclusions: In the present study, it can be inferred that there was a positive association between hospital morbidity rate and prevalence of smoking, while it was not possible to observe a correlation between lung cancer mortality rate and prevalence of smoking.

Introducción: El cáncer de pulmón es una enfermedad grave, siendo la segunda causa de muerte en todo el mundo, sin embargo, en algunos países desarrollados, ya se ha convertido en la primera causa de muerte. Alrededor del 90% de los casos de neoplasias pulmonares están causados por la inhalación del humo del cigarrillo. Objetivo: Correlacionar la prevalencia de tabaquismo y la morbimortalidad por cáncer de pulmón en los estados brasileños, además de demostrar la asociación de estos con el género y el grupo de edad. Métodos: estudio ecológico sobre la prevalencia de tabaquismo y morbimortalidad por cáncer de pulmón en los estados brasileños, dentro de los períodos 2013 y 2019, divididos por sexo y grupo de edad. Se utilizaron bancos de recogida de datos como Tabnet y la Encuesta Nacional de Salud. Resultados: las mayores tasas de mortalidad e ingresos hospitalarios se dieron en el público masculino, en 2013 con una tasa de 2,7 y 10, respectivamente, y en 2019 con 3,3 y 11,9, respectivamente. Además, la mayor prevalencia del tabaquismo se encontró en los hombres, sin embargo, su tasa ha disminuido, mientras que la cantidad de mujeres fumadoras ha aumentado. La región Sur presentó cifras más altas de mortalidad en ambos periodos estudiados, con tasas de 4,9 y 5,8 por 100.000 habitantes, y de morbilidad hospitalaria con 19,9 y 23,5 por 100.000 habitantes. Mientras que la región Norte se configuró con las prevalencias más bajas, en 2013 presentó una tasa de mortalidad por cáncer de pulmón de 1,0 y una morbilidad hospitalaria de 3,5/100.000 habitantes, en 2019 presentó una tasa de mortalidad de 4,6 y hospitalizaciones de 1,6/100.000 habitantes. Los coeficientes de correlación para la morbilidad hospitalaria y la prevalencia del tabaquismo fueron R2=0,0628, r=0,251 y p=0,042, mientras que para la mortalidad y la prevalencia del tabaquismo fueron R2=0,0337, r=0,183 y p=0,140. Conclusiones: En la presente investigación se puede inferir que existe una asociación positiva en la comparación entre la tasa de morbilidad hospitalaria y la prevalencia de tabagismo, en contrapartida, no fue posible observar una asociación positiva en la correlación de la tasa de mortalidad por cáncer de pulmón y la prevalencia de tabagismo.

Asociación entre obesidad abdominal, consumo de alcohol y actividad física en universitarios panameños / Association between abdominal obesity, alcohol consumption and physical activity in Panamanian college students

Introducción. La obesidad abdominal es considerada un factor de riesgo de enfermedad cardiovascular y diabetes. El consumo excesivo episódico de alcohol y la inactividad física también son factores de riesgo comportamentales asociados a enfermedades no transmisibles. Objetivo: Analizar la asociación entre la obesidad abdominal, el consumo de alcohol y la inactividad física en universitarios panameños. Materiales y métodos: Estudio transversal analítico realizado en 374 estudiantes universitarios panameños en el periodo abril ­ diciembre de 2021. Se implementó el cuestionario para la vigilancia de factores de riesgo de enfermedades no transmisibles de la Organización Mundial de la Salud y se evaluó la circunferencia de cintura. La obesidad abdominal se estableció con una circunferencia de cintura ≥80 cm en mujeres y ≥90 cm en hombres. Se realizaron análisis descriptivos, bivariados y múltiples usando modelos de regresión logística para determinar la asociación entre las variables del estudio. Las pruebas U Mann-Whitney y Chi cuadrado fueron utilizadas para analizar diferencias por sexo. Resultados: Una tercera parte de los universitarios participantes presentaron obesidad abdominal. Las mujeres reportaron mayores niveles de inactividad física (<0,0001) y conducta sedentaria (p=0,0010) que los hombres. Después de ajustar por sexo, edad y nivel socioeconómico, la obesidad abdominal estuvo asociada con la inactividad física (OR: 1,762, IC 95%: 1,040 ­ 2,985, p=0,035) y el consumo excesivo episódico de alcohol (OR 1,114, IC: 1,015 ­ 1,223, p=0,023). Conclusiones: Los universitarios panameños que reportaron bajos niveles de actividad física y consumo excesivo episódico de alcohol tuvieron una mayor probabilidad de registrar obesidad abdominal(AU)

Introduction. Abdominal obesity is considered a risk factor for cardiovascular disease and diabetes. Episodic excessive consumption of alcohol and physical inactivity are behavioral risk factors associated with non-communicable diseases. Objective: To analyze the association between abdominal obesity, alcohol consumption and physical inactivity in Panamanian university students. Materials and methods: Analytical cross-sectional study conducted on 374 Panamanian university students in the period April ­ December 2021. The questionnaire for the surveillance of risk factors for non-communicable diseases of the World Health Organization was implemented and waist circumference was evaluated. Abdominal obesity was established with a waist circumference ≥80 cm in women and ≥90 cm in men. Descriptive, bivariate, and multiple analyzes were performed using logistic regression models to determine the association between the study variables. The Mann-Whitney U and Chi square tests were used to analyze differences by sex. Results: A third of the participating university students had abdominal obesity. Women reported higher levels of physical inactivity (<0,0001) and sedentary behavior (p=0,0010) than men. After adjusting for sex, age and socioeconomic status, abdominal obesity was associated with physical inactivity (OR: 1,762, 95% CI: 1,040 ­ 2,985, p=0,035) and episodic heavy alcohol consumption (OR 1,114, CI: 1,015 ­ 1,223, p=0,023). Conclusions: Students who reported low levels of physical inactivity and binge drinking were more likely to have abdominal obesity(AU)

Herramientas para el tamizaje de aneurisma de aorta abdominal / Tools for abdominal aortic aneurysm screening

Introducción. El aneurisma de la aorta abdominal (AAA) es la dilatación de la aorta abdominal mayor de 1,5 veces el diámetro esperado. Su prevalencia es variable, con tasas reportadas de hasta el 12,5 %. Se considera como causa de muerte de más de 10.000 personas al año en los Estados Unidos. El objetivo de esta revisión de la literatura fue describir los factores de riesgo y las herramientas de tamizaje de AAA. Métodos. Se realizó una búsqueda de la literatura utilizando dos ecuaciones en bases de datos electrónicas, empleando términos seleccionados de "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Se evaluó la calidad de los estudios con la herramienta STROBE (Strengthening the Reporting of Observational Studies in Epidemiology). Resultados. Se recolectaron 40 artículos y a partir de ellos se construyó el texto de revisión, identificando en estos, los factores de riesgo asociados al desarrollo de AAA, tales como sexo masculino, tabaquismo, hipertensión arterial, antecedente familiar y obesidad, entre otros. La diabetes mellitus parece actuar como factor protector. Dentro de los instrumentos de tamizaje, el ultrasonido abdominal es uno de los más usados. Conclusión. El AAA es una patología multifactorial. En la actualidad la ultrasonografía de aorta es el método de elección para el tamizaje, permitiendo la detección precoz. El tamizaje de AAA con métodos no invasivos, como el ultrasonido, es útil sobre todo en zonas con prevalencia alta de la patología y en pacientes con determinados factores de riesgo.

Introduction. Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta greater than 1.5 times the expected diameter. Its prevalence is variable, with reported rates of up to 12.5%. It is considered the cause of death of more than 10,000 people a year in the United States. The objective of this literature review was to describe risk factors and screening tools for AAA. Methods. A literature search was conducted using two equations in electronic databases, using terms selected from "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). The quality of the studies was evaluated with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) tool. Results. Forty articles were collected and from them the review text was constructed, identifying the risk factors associated with the development of AAA, such as male sex, smoking, high blood pressure, family history and obesity, among others. Diabetes mellitus seems to act as a protective factor. Among the screening instruments, abdominal ultrasound is one of the most used. Conclusion. AAA is a multifactorial pathology. Currently, aortic ultrasonography is the method of choice for screening, allowing early detection. Screening for AAA with non-invasive methods, such as ultrasound, is useful especially in areas with a high prevalence of this pathology and in patients with certain risk factors.

Oral health of an indigenous population in northeastern Brazil: a cross-sectional Study of the Fulni-ô ethnic group

ABSTRACT BACKGROUND: There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil. OBJECTIVES: Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil. DESIGN AND SETTING: A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations. METHODS: This study included participants of both sexes from the Fulni-ô ethnic group. The participants included in this investigation underwent a comprehensive oral health evaluation by a registered and experienced dentist to assess oral health and identify potentially malignant oral lesions. Participants with suspicious lesions were referred for biopsy. Shapiro-Wilk, Mann-Whitney, and Student's t-tests were used, and measures of central tendency and dispersion were described. Statistical significance was 5%. RESULTS: A total of 104 individuals were included in this study. The prevalence of the use of tobacco derivatives was 94.0%, with similarities between sexes. The prevalence of oral changes in this study population was 84.4%. Fifty-one individuals who underwent oral reassessment were referred for oral lesion biopsy. CONCLUSIONS: This study demonstrated a high prevalence of oral alterations in the Fulni-ô population. Histopathological analyses indicated the presence of mild oral epithelial dysplasia in five cases.

Lung cancer screening in Brazil: recommendations from the Brazilian Society of Thoracic Surgery, Brazilian Thoracic Association, and Brazilian College of Radiology and Diagnostic Imaging / Recomendações da Sociedade Brasileira de Cirurgia Torácica, Sociedade Brasileira de Pneumologia e Tisiologia e Colégio Brasileiro de Radiologia e Diagnóstico por Imagem para o rastreamento do câncer de pulmão no Brasil

ABSTRACT Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

RESUMO O câncer de pulmão (CP) é uma das neoplasias mais comuns e letais no Brasil, e apenas 15% dos pacientes são diagnosticados nos estágios iniciais. O tabagismo persiste como o responsável por mais de 85% de todos os casos. O rastreamento do CP (RCP) por meio da TC de baixa dosagem de radiação (TCBD) reduz a mortalidade do CP em 20%, e, quando combinado com a cessação do tabagismo, essa redução chega a 38%. Na última década, diversos países adotaram o RCP como recomendação de saúde populacional. No Brasil, embora ainda incipiente, a discussão sobre o tema é cada vez mais ampla e necessária. Com o intuito de aumentar o conhecimento e estimular o debate sobre o RCP, a Sociedade Brasileira de Cirurgia Torácica, a Sociedade Brasileira de Pneumologia e Tisiologia e o Colégio Brasileiro de Radiologia e Diagnóstico por Imagem constituíram um painel de especialistas para elaborar as recomendações para o RCP. As recomendações aqui apresentadas foram baseadas em revisão narrativa da literatura, com ênfase em grandes estudos populacionais, em revisões sistemáticas e em recomendações de diretrizes internacionais, sendo construídas após ampla discussão pelo grupo de especialistas. Os temas revisados foram os seguintes: porque rastrear, considerações gerais sobre tabagismo, epidemiologia do CP, critérios de elegibilidade, achados incidentais, lesões granulomatosas, modelos probabilísticos, requisitos mínimos da TCBD, aquisições volumétricas, riscos do rastreamento, estrutura mínima e papel da equipe multidisciplinar, conduta segundo o Lung CT Screening Reporting and Data System (Lung-RADS), custos vs. benefícios e perspectivas do rastreamento.

Effect of tobacco smoking on outcomes of trabeculectomy / Efeito do tabagismo nos desfechos da trabeculectomia

ABSTRACT Purpose: To evaluate the effect of tobacco smoking on trabeculectomy outcomes. Methods: Charts of patients with glaucoma who underwent trabeculectomy performed by a single surgeon between 2007 and 2016 were retrospectively reviewed. Charts were screened for a documented history of smoking status before surgery. Demographic and clinical preoperative variables were recorded. Based on smoking history, subjects were divided into two groups: smokers and nonsmokers. Any bleb-related interventions (e.g., 5-flourouracil injections ± laser suture lysis) or bleb revision performed during the postoperative period were noted. Success was defined as an intraocular pressure >5 mmHg and <21 mm Hg without (complete success) or with (qualified success) the use of ocular hypotensive medications. Failure was identified as a violation of the criteria mentioned above. Results: A total of 98 eyes from 83 subjects were included. The mean age of the subjects was 70.7 ± 11.09 years, and 53% (44/83) were female. The most common diagnosis was primary open-angle glaucoma in 47 cases (47.9%). The smokers Group included 30 eyes from 30 subjects. When compared with nonsmokers, smokers had a significantly worse preoperative best-corrected visual acuity (p=0.038), greater central corneal thickness (p=0.047), and higher preoperative intraocular pressure (p=0.011). The success rate of trabeculectomy surgery at 1 year was 56.7% in the smokers Group compared with 79.4% in the Group nonsmokers (p=0.020). Smoking presented an odds ratio for failure of 2.95 (95% confidence interval, 1.6-7.84). Conclusion: Smokers demonstrated a significantly lower success rate 1 year after trabeculectomy compared with nonsmokers and a higher requirement for bleb-related interventions.

RESUMO Objetivo: Avaliar o efeito do tabagismo nos desfechos da trabeculectomia. Métodos: Uma revisão retrospectiva do gráfico de pacientes com glaucoma submetidos à trabeculectomia foi realizada por um único cirurgião entre 2007 e 2016. Os gráficos foram examinados para uma história documentada de condição de fumante antes da cirurgia. Variáveis pré-operatórias clínicas e demográficas e clínicas foram registradas. Os pacientes foram divididos em dois grupos de acordo com sua história de tabagismo em fumantes e não fumantes. Quaisquer Intervenções relacionadas à bolha, por exemplo, injeções de 5-fluorouracil + lise de sutura com laser, ou revisão da bolha realizada durante o período pós-operatório foram observadas. O sucesso foi definido como pressão intraocular > 5 mmHg e < 21 mm Hg sem (sucesso completo) ou com (sucesso qualificado) medicamentos hipotensores oculares. A falha foi identificada como violação dos critérios mencionados acima. Resultados: O estudo incluiu 98 olhos de 83 pacientes com idade média de 70,7 ± 11,09 anos, sendo 53% (44/83) dos pacientes do sexo feminino. O diagnóstico mais comum foi o glaucoma de ângulo aberto primário com 47 casos (47,9%). O Grupo de fumantes incluiu 30 olhos de 30 pacientes. Os fumantes, quando comparados aos não fumantes, apresentaram uma melhor acuidade visual pré-operatória significativamente pior (p=0,038), maior espessura central da córnea (p=0,047) e maior pressão intraocular pré-operatória (p=0,011). A taxa de sucesso de um ano para a cirurgia de trabeculectomia foi de 56,7% no Grupo de fumantes contra 79,4% no Grupo de não fumantes (p=0,020). O tabagismo apresentou razão de chances para falha de 2,95 95% de IC (1,6-7,84). Conclusão: Os fumantes demonstraram uma taxa de sucesso significativamente menor em um ano após a trabeculectomia em comparação com os não fumantes e uma maior necessidade de intervenções relacionadas à bolha.

Smoking and consumption of ultra-processed foods — a combination of risky choices: A cross-sectional study using Vigitel 2018 data

ABSTRACT BACKGROUND: Smoking and unhealthy diet are important risk factors for cardiovascular and metabolic diseases, contributing to public health crises. OBJECTIVE: To evaluate the consumption of natural/minimally processed and ultra-processed foods by Brazilian adults (18-59 years old) according to smoking status. DESIGN AND SETTING: Cross-sectional study of a representative population sample from 26 state capitals and the Federal District (Brazil-2018). METHODS: Data were obtained from Vigitel—Surveillance System for Risk and Protection Factors for Chronic Diseases by Telephone Survey. Participants were categorized as smokers, ex-smokers, and never smokers. Multinomial logistic regression was used for analyses. RESULTS: Of the 30,800 adults evaluated, 9.4% (95%CI: 8.7-10.2) were smokers and 16.5% (95%CI: 15.8-17.3) were ex-smokers. Smokers were less likely to consume fruit and natural juice, and more likely to consume soda or artificial juice (≥ 5 days/week) than ex-smokers and never smokers. Regarding the daily frequency of consumption, smokers were observed to be less likely to eat fruit more than 1 time/day and more likely to drink ≥ 3 cups/cans of soda/day. Compared to never smokers, smokers had a 42% higher chance of consuming ≥ 3 glasses of natural juice/day. On the day before the interview, fruit, milk, tubers, squash, and okra consumption were lower among smokers than non-smokers. Smokers were more likely to report consuming soft drinks, fruit juice, sauces, ready-made dishes, margarine, and sausages. CONCLUSION: Smokers had lower fruit consumption, and higher consumption of natural juices and ultra-processed foods. We highlight the need for strategies that encourage healthy eating and smoking cessation.

Smoking, mortality, access to diagnosis, and treatment of lung cancer in Brazil / Tabagismo, mortalidade, acesso ao diagnóstico e tratamento de câncer de pulmão no Brasil

ABSTRACT INTRODUCTION Lung cancer (LC) is a relevant public health problem in Brazil and worldwide, given its high incidence and mortality. Thus, the objective of this study is to analyze the distribution of smoking and smoking status according to sociodemographic characteristics and disparities in access, treatment, and mortality due to LC in Brazil in 2013 and 2019. METHOD Retrospective study of triangulation of national data sources: a) analysis of the distribution of smoking, based on the National Survey of Health (PNS); b) investigation of LC records via Hospital-based Cancer Registry (HCR); and c) distribution of mortality due to LC in the Mortality Information System (SIM). RESULTS There was a decrease in the percentage of people who had never smoked from 2013 (68.5%) to 2019 (60.2%) and in smoking history (pack-years). This was observed to be greater in men, people of older age groups, and those with less education. Concerning patients registered in the HCR, entry into the healthcare service occurs at the age of 50, and only 19% have never smoked. While smokers in the population are mainly Mixed-race, patients in the HCR are primarily White. As for the initial stage (I and II), it is more common in White people and people who have never smoked. The mortality rate varied from 1.00 for people with higher education to 3.36 for people without education. Furthermore, White people have a mortality rate three times higher than that of Black and mixed-race people. CONCLUSION This article highlighted relevant sociodemographic disparities in access to LC diagnosis, treatment, and mortality. Therefore, the recommendation is to strengthen the Population-Based Cancer Registry and develop and implement a nationwide LC screening strategy in Brazil since combined prevention and early diagnosis strategies work better in controlling mortality from the disease and continued investment in tobacco prevention and control policies.

RESUMO INTRODUÇÃO O câncer de pulmão (CP) é um relevante problema de saúde pública no Brasil e no mundo, dada sua alta incidência e mortalidade. Assim, objetiva-se analisar a distribuição do tabagismo e da carga tabágica segundo características sociodemográficas e disparidades no acesso, no tratamento e na mortalidade por CP no Brasil, em 2013 e 2019. MÉTODO Estudo retrospectivo de triangulação de fontes de dados de abrangência nacional: a) análise da distribuição do tabagismo, baseada na Pesquisa Nacional de Saúde (PNS); b) investigação dos registros de CP, via Registros Hospitalares de Câncer (RHC); e c) distribuição da mortalidade por CP, no Sistema de Informação sobre Mortalidade (SIM). RESULTADOS Verificou-se redução do percentual de pessoas que nunca fumaram de 2013 (68,5%) para 2019 (60,2%), assim como da carga tabágica (anos-maço). Esta foi observada maior em homens em pessoas de faixas etárias mais avançadas e de menor escolaridade. Em relação aos pacientes registrados no RHC, a entrada no serviço de saúde se dá a partir de 50 anos, e apenas 19% nunca fumaram. Ao passo que os fumantes na população são majoritariamente pardos, os pacientes no RHC são em maioria brancos. Quanto ao estadiamento inicial (I e II), é mais frequente em pessoas brancas e que nunca fumaram. A taxa de mortalidade apresentou variação de 1,00, para pessoas com ensino superior, a 3,36, entre pessoas sem instrução, assim como pessoas brancas têm uma taxa de mortalidade três vezes maior que a de pessoas negras e pardas. CONCLUSÃO Este artigo apontou relevantes disparidades sociodemográficas no acesso ao diagnóstico, tratamento e mortalidade do CP. Assim, recomenda-se: fortalecer o Registro de Câncer de Base Populacional; desenvolver e implementar estratégia de screening de CP no Brasil, uma vez que a realização de estratégias de prevenção e diagnóstico precoce combinadas funcionam melhor no controle da mortalidade pela doença; e investimento contínuo nas políticas de prevenção e controle do tabagismo.

Mudanças no uso do tabaco entre adolescentes brasileiros e fatores associados: Pesquisa Nacional de Saúde do Escolar / Changes in tobacco use and associated factors among Brazilian adolescents: National Student Health Survey

Resumo O estudo objetiva comparar o consumo de diferentes produtos do tabaco entre os escolares adolescentes no Brasil em 2015 e 2019 e identificar os fatores associados ao seu uso. Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015 e 2019. Variáveis: uso atual de cigarro, uso de outros produtos do tabaco e uso de qualquer produto do tabaco. Foi usado o teste do Qui-quadrado de Pearson para verificar associação entre as variáveis, realizada análise bivariada e a multivariada por meio da regressão logística. O uso de cigarros se manteve estável entre 2015 (6,6%) e 2019 (6,8%). Mas houve aumento do uso de qualquer produto do tabaco (de 10,6% em 2015 para 14,8% em 2019), sendo o narguilé o mais frequente (7,8%) seguido do cigarro eletrônico (2,8%). O uso de cigarro foi mais elevado entre os adolescentes de 16 e 17 anos, com cor da pele preta e parda, que faltaram as aulas sem autorização, entre aqueles que relataram não ter amigos, que apresentavam outros fatores de risco como consumir bebidas alcoólicas e que eram fumantes passivos. A prevalência de tabagismo aumentou ao longo dos anos e foi associada com aspectos sociodemográficos e a outros comportamentos de risco à saúde, o que alerta para a necessidade de ações de promoção da saúde ao longo do ciclo de vida.

Abstract This cross-sectional study used data from Brazil's National Student Health Survey (PeNSE), from 2015 and 2019, to compare consumption of tobacco products among adolescent students in Brazil and identify associated factors. The study variables were current cigarette smoking, use of other tobacco products and use of any tobacco product. Pearson's Chi-square test was used to ascertain associations between the variables; bivariate and multivariate analyses were performed using logistic regression. Cigarette smoking remained stable between 2015 (6.6%) and 2019 (6.8%), but use of any tobacco product increased (from 10.6% in 2015 to 14.8% in 2019), involving particularly hookahs (7.8%) and e-cigarettes (2.8%). Cigarette smoking was greater among adolescents aged 16 and 17, whose skin colour was black or brown, who missed classes without permission, who reported having no friends, displayed other risk factors, such as drinking alcoholic beverages, or who were passive smokers. The prevalence of smoking has increased over the years and is associated with sociodemographic aspects and other health risk behaviour, highlighting the need for lifelong health promotion actions.

Prevalencia y evaluación diagnóstica inicial del hábito tabáquico en adolescentes de Moa, Holguín

Fundamento el tabaquismo en la adolescencia constituye un problema de salud pública mundial, al punto de ser considerado la principal causa prevenible de enfermedad y muerte prematura. Objetivo describir el comportamiento del tabaquismo en adolescentes. Métodos estudio de corte transversal, realizado en el periodo septiembre-diciembre de 2022. De un universo de 1561 adolescente de 15-19 años de edad, se seleccionó una muestra de 1444 (92,50 %) mediante muestreo deliberado. Las variables del estudio: edad, sexo, fumador, exfumador, edad de inicio, años fumando, número de cigarrillos consumidos por día, carga tabáquica, dependencia y motivación. Resultados la prevalencia de tabaquismo resultó de 17,94 %. El 0,83 % de los adolescentes expresó haber abandonado el hábito (exfumadores). El 55,98 % tenía entre 17-18 años de edad, y el 77,61 % perteneció al sexo masculino. El 64,86 % comenzó a fumar entre los 12 y 14 años, el 52,51 % fumaba desde hacía 1-2 años; mientras un 59,85 % consumía entre 6-10 cigarrillos diarios. La carga tabáquica recibida por el 44,34 % resultó 0,25-0,50. El 57,08 % declaró dependencia física baja, y el 81,13 % motivación baja. Conclusiones la prevalencia del tabaquismo en los adolescentes de Moa fue similar a la reportada por otras investigaciones. Resulta preocupante que más de la mitad de la población estudiada consuma cigarros desde los 12-14 años, y que, a pesar de mostrar bajos niveles de dependencia, no sientan motivación por abandonar este mal hábito.

From a universe of 1,561 adolescents aged 15-19, a sample of 1,444 (92.50%) was selected through deliberate sampling. The study variables: age, sex, smoker, ex-smoker, age of initiation, years of smoking, number of cigarettes consumed per day, smoking load, dependence and motivation. Results the prevalence of smoking was 17.94%. 0.83% of adolescents expressed having quit the habit (ex-smokers). 55.98% were between 17-18 years of age, and 77.61% were male. 64.86% started smoking between 12 and 14 years old, 52.51% had been smoking for 1-2 years; while 59.85% consumed between 6-10 cigarettes a day. The smoking burden received by 44.34% was 0.25-0.50. 57.08% declared low physical dependence, and 81.13% reported low motivation. Conclusions the prevalence of smoking in Moa adolescents was similar to that reported by other investigations. It is worrying that more than half of the population studied consumes cigarettes from the age of 12-14, and that, despite showing low levels of dependence; they do not feel motivated to abandon this bad habit.

Tabaco y tabaquismo en Cuba: de la economía agrícola a la economía de la salud

El consumo de cigarrillos y tabacos crea una externalidad que tiene mayor relevancia en el detrimento de la calidad de vida y de la expectativa de vida que experimenta el individuo fumador con relación a los que no consumen cigarrillos o tabacos. el costo psicosocial no cuantificado de forma financiera supera con creces cualquier expectativa de beneficio económico. El presente artículo versa en torno al impacto socioeconómico del tabaquismo en Cuba. La distribución económica inducida por el tabaquismo conlleva a la persistencia de una inequidad socioeconómica tal, que se agudiza con el número de fumadores y la intensidad del consumo de cigarrillos y tabáquico. Este fenómeno contradice el principio socialista de distribución con arreglo al trabajo, donde los no fumadores no deberían cargar con las consecuencias del tabaquismo y los propios fumadores no deberían ser inducidos a persistir en el consumo tabáquico. La sutileza de los costos sociales atribuibles al tabaquismo y el impacto de los beneficios del comercio interior y exterior, no permiten valorar en su completa dimensión los principales efectos del tabaquismo desde el aspecto socioeconómico.

The cigarettes and tobacco consumption creates an externality that is more relevant in the detriment of the life quality and life expectancy experienced by the individual smoker, in relation to those who do not consume cigarettes or tobacco. The psychosocial cost not financially quantified far exceeds any expectation of economic benefit. This article deals with the socioeconomic impact of smoking in Cuba. The economic distribution induced by smoking leads to the persistence of such socioeconomic inequity, which worsens with the number of smokers and the intensity of cigarette and tobacco consumption. This phenomenon contradicts the socialist principle of distribution according to work, where non-smokers should not bear the consequences of smoking and smokers themselves should not be induced to persist in smoking. The subtlety of the social costs attributable to smoking and the impact of the benefits of domestic and foreign trade do not allow a full assessment of the main effects of smoking from the socioeconomic aspect.

Tobacco Use: Quitting Plan, Attempts and Obstacles for Cessation- A Cross-Sectional Study from A Sub-Urban Neighbourhood of Chennai-Tamil Nadu

Introduction: Tobacco consumption is a preventable public health problem. GATS -2 survey in Tamil Nadu shows that 20% of adults use tobacco, 40% had plans to quit and 48% had made quit attempts. The purpose of the study was to assess factors associated with tobacco use; quitting plan, attempts and identify obstacles for tobacco cessation. Methods: A Cross-sectional study was done among 300 tobacco users in a suburban neighbourhood of Chen-nai and data was analysed using SPSS software. Results: Ninety five percent were smokers and 86% smoked cigarettes. 70% knew that it causes cancer and respiratory diseases. 60% planned to quit, 69% made quit attempts. Those with quit plans and health prob-lems had an increased odds (AOR of 1.02 and 1.004 respectively) of making quit attempts. Advice from health professionals (48%) and family (52%) triggered quit attempts. Stress and work pressure were obstacles for quitting (70%). Availability of therapy and professional help for tobacco cessation was known only to 49% and 14.7% respectively and none availed it. Conclusion: Awareness of health hazards of tobacco use was high. Quit attempts have increased but with high failure rates due to lack of information and access to tobacco cessation services. Provision of community and facility-based tobacco cessation services and integration with existing health programmes is the present need.

Current status of cigarette use and exposure to second-hand smoke and associated factors among college students in Zhejiang / 中华健康管理学杂志

Objective:To describe the prevalence of tobacco use among college students in Zhejiang Province and analyze the influencing factors of second-hand smoke exposure on campus.Methods:In 2021, college students were selected from 9 colleges through stratified multi-stage cluster sampling from Zhejiang Province and surveyed using questionnaire. A total of 6 530 questionnaires were distributed and 6 035 were returned, with 6 030 valid questionnaires (96.48%). A descriptive analysis of the demography characteristics, cigarettes and electronic cigarettes (e-cigarettes) use, and second-hand smoke exposure of the subjects was carried out, and chi-square test was used for statistical analysis and multivariate logistic regression analysis was used to analyze influencing factors of second-hand smoke exposure on campus.Results:The current smoking rate and current use rate of e-cigarettes among college students were 3.70% and 1.56%, respectively, and the dual use rate of cigarettes and e-cigarettes was 1.16%. The exposure rate of second-hand smoke among college students on campus was 25.06%, while the exposure rate of second-hand smoke in off campus places was 32.35%. The awareness rates of smoking related diseases among college students were as follows: lung cancer (92.02%), heart disease (73.15%), stroke (72.87%), and impotence (64.08%). The awareness rate of second-hand smoke related diseases were as follows: lung cancer in adults (91.11%), heart disease in adults (78.91%), and lung disease in children (89.35%). The multivariate logistic regression analysis showed that seven factors (including gender, school type, major, grade, smoking ban regulations, smoking scenes, and knowledge about the health hazards of second-hand smoke) had a statistically significant impact on college students′ exposure to second-hand smoke at school [ OR=2.63, 0.67, 0.69, (0.39, 0.60, 0.68), 0.51, 1.74, 0.72] (all P<0.01). Conclusions:The use of cigarettes and e-cigarettes among college students in Zhejiang Province is not optimistic, especially the use rate of e-cigarettes is higher than adult. The status of second-hand smoke exposure among college students remains serious, with male students, non-medical students, students of special programs, and senior college students having more severe second-hand smoke exposure on campus, and students with high awareness of second-hand smoke exposure, less exposure to smoking scenes from media, from college with comprehensive smoke-free regulations are less exposed to second-hand smoke on campus.

Does higher tax rate affect tobacco usage?Unravelling the nexus between tobacco regulatory control and public health concern / 《全球健康杂志（英文）》

Objectives:Bangladesh stands as a prominent global consumer of tobacco,with alarming consequences on public health.The Global Adult Tobacco Survey reported that tobacco consumption claimed over 126 000 lives in 2018,contributing to 13.5％of all deaths in the country.This study aims to explore the effectiveness of higher tax rates and tobacco use regulation as control mechanisms in mitigating tobacco consumption and health care cost burden,with a particular emphasis on its implications for public health. Methods:This study is based on the annual time series data over the period 2000-2020.The study employs the ordinary least square method to analyze the quantitative confirming the stationarity of data at level.This research uses different models to investigate individual effects and combined effects on both tobacco consumption and tobacco health care cost burden. Results:The study finds a negative relationship between tobacco tax rate and tobacco consumption.More specif-ically,the higher tax rate of tobacco(low(β=-0.3495),medium(β=-0.2319),high(β=-0.9033),premium(β=-0.7322),filtered(β=-0.2114),and non-filtered(β=-0.3452)categories)is significant to reduce tobacco use at 1％level of significance.The study finds similar results when it applied tobacco retail price instead of to-bacco tax rate as the independent variable.Finally,the study investigates the impact on health care cost through tobacco consumption,tobacco control law,growth rate,export-import,and tobacco production.The results in-dicate that tobacco consumption,export-import,and tobacco production increases health care cost burden while tobacco use regulatory decreases it.By reducing tobacco consumption,higher taxes and tobacco use regulation contribute to alleviating the burden on the healthcare system,promoting healthier lifestyles,and aligning with global health objectives. Conclusions:Higher tax rate on tobacco products is necessary to increase the retail price so that tobacco users cannot consume tobacco.Specific tax and uniform tax base are needed so that tobacco users cannot switch to lower priced brands.Tobacco control laws need to revised and proper implementation should be ensured as well,to achieve the goal of tobacco free Bangladesh by 2040.Tobacco-related diseases,responsible for a significant proportion of deaths in the country,could witness a considerable decline with the successful implementation of higher tax rates and tobacco use regulation.This study provides insights that not only contribute to the eco-nomic discourse but also accentuate the broader public health benefits arising from effective tobacco taxation policies.

Effects of educational level on the choice of intervention strategies for smoking cessation in patients with moderate to severe tobacco dependence / 中国基层医药

Objective:To investigate the effects of educational level on smoking cessation in patients with moderate to severe tobacco dependence, explore effective individualized smoking cessation methods, and increase smoking cessation rate.Methods:A total of 480 patients with moderate to severe tobacco dependence who were willing to quit smoking and received treatment in the Department of Respiratory and Critical Care Medicine, Shengli Oilfield Central Hospital from January to December 2020 were included in this study. They were divided into four groups ( n = 120/group) according to their educational level: group A (elementary school and below), group B (junior high school and senior high school), group C (technical secondary school or college), and group D (university and above). All patients were randomly assigned to undergo "5A" intervention alone or "5A" intervention combined with varenicline intervention (combined intervention). Patients' awareness of the health risks of tobacco smoking was compared among the four groups. The smoking cessation rate measured at different time points was compared between different intervention strategies. Results:The scores of health risk of tobacco smoking in groups D, C, B, and A were (806.5 ± 35.7) points, (710.8 ± 26.2) points, (643.6 ± 43.4) points, and (512.4 ± 30.1) points, respectively. Patients with high education levels had high awareness of the health risk of tobacco smoking ( F = 1 543.26, P < 0.001). At 1, 3, and 6 months, the smoking cessation rate of combined intervention was higher than that of "5A" intervention alone in each group (group A: χ2 = 3.85, 4.23, 4.10, group B: χ2 = 4.30, 4.09, 4.60, group C: χ2 = 6.81, 4.30, 4.03, group D: χ2 = 6.71, 6.51, 4.73, all P < 0.05). The smoking cessation rate after 6 months of "5A" intervention alone or combined intervention in group D was 60.0% and 78.3% respectively, which were significantly higher than 41.7% and 60.0% in group C, 23.3% and 41.7% in group B, and 20.0% and 36.7% in group A ( χ2 = 26.59, 26.12, both P < 0.001). At different time points, the smoking cessation rates of the "5A" intervention alone in group D were significantly higher than those of combined intervention in groups A and B ( χ2 = 9.25, 25.04, 7.29, all P < 0.05). Conclusion:Awareness of the health risks of tobacco smoking is related to a patient's educational level, and affects smoking cessation. Individualized smoking cessation interventions based on a patient's educational level can increase the rate of smoking cessation.

Effect of mental health on tobacco use among adolescents in rural Sichuan： mediation of life satisfaction / 上海预防医学

ObjectiveTo understand the current situation of tobacco use among rural adolescents in Sichuan Province and its influencing factors， to explore the relationship between smoking behavior and psychosocial influencing factors of rural adolescents in Sichuan Province， and to provide a scientific basis for the prevention and control of smoking among rural adolescents. MethodsAn "Adolescent Health Questionnaire" was used as the survey tool to investigate 2 671 students in the 8th and 11th grades of two township middle schools in Zizhong County， Sichuan Province. The structural equation model in Mplus 7.0 was used to analyze the relationship between adolescent tobacco use behavior， mental health， and life satisfaction. ResultsAmong the surveyed adolescents， 28.3% （756/2 671） had tried tobacco products， and 9.5% （255/2 671） had used tobacco products in the past 30 days. The prevalence of tobacco use was higher among boys （16.6%） than girls （3.5%）， and among 11th grade students （21.9%） compared to 8th grade students （7.3%）， with statistically significant differences （χ2=131.99 and 4.24， both P<0.05）. The current tobacco use rate increased with the increase in monthly allowance （χ2=46.96， P<0.05）. The structural equation model of smoking behavior showed that mental health had a positive and direct impact on smoking behavior， and an indirect impact on smoking behavior through living environment satisfaction. Living environment satisfaction had a negative and direct impact on smoking behavior with the mediating effect accounting for 19.2% of the total effect. The non-standardized mediating effect of mental health on smoking behavior through life environment satisfaction and its 95%CI were 0.007 （0.002‒0.012）. ConclusionAdolescent smoking behavior is a complex psychosocial behavior， and the situation of adolescent tobacco use in rural areas in Sichuan is severe. There is a correlation between adolescent tobacco use behavior and psychosocial influencing factors. Psychosocial influencing factors can predict adolescents’ tobacco use behavior. Attention should be paid to the important role of psychosocial influencing factors when intervening in rural adolescents’ smoking behavior.
