Factors associated with delayed initiation of breast cancer treatment at an oncology referral center in Juiz de Fora, Minas Gerais state, from 2010 to 2019: a cohort study.

OBJECTIVES: To analyze factors associated with delayed initiation of breast cancer treatment at an oncology referral center in Juiz de Fora, Minas Gerais state, between 2010 and 2019. METHODS: This was a cohort study using data from the Hospital-based Cancer Registry. The probability of not starting treatment within 60 days, in accordance with Brazilian law, was estimated using Kaplan-Meier, method and its association with the factors studied was assessed using the Cox model, presenting hazard ratios (HR) and respective 95% confidence intervals (95%CI). RESULTS: Among the 911 participants, the probability of delayed treatment initiation was 18.8% (95%CI 16.4;21.5). Those who underwent treatment at a health service other than the one where the cancer was diagnosed had a significantly higher risk (HR: 3.49; 95%CI 3.00;4.07). CONCLUSION: Receiving a diagnosis and treatment at the same institution may help reduce waiting time to initiate cancer treatment. MAIN RESULTS: The probability of study participants not initiating treatment within 60 days was 18.8%. Undergoing treatment at a healthcare service other than the one where the diagnosis was made was the main factor associated with delay. IMPLICATIONS FOR SERVICES: Organizing healthcare services based on strategies that optimize referral flows and avoid transitions of care, can be crucial in reducing the time to initiation of breast cancer treatment. PERSPECTIVES: It is essential to improve the workflows at the different stages of health care to ensure timely initiation of oncological treatment.

[What does the Brazilian National Health Survey have to say about the influence of cigarette spending on household income?] / O que a Pesquisa Nacional de Saúde tem a dizer sobre a influência do gasto com cigarro no rendimento domiciliar?

In a country whose indicators of population impoverishment continue to increase, it is concerning that individuals spend money to buy cigarettes instead of using this resource in actions that strengthen aspects of the well-being of their lives and that of their families. Based on the Brazilian National Health Survey conducted in 2019, the influence of spending on manufactured cigarettes on the family budget in households with at least one smoker was estimated, stratified by sociodemographic characteristics. Brazilian smokers allocated around 8% of their average per capita monthly household income to the purchase of manufactured cigarettes. The percentage of average monthly expenditure on cigarettes reached almost 10% of this income among smokers aged 15 to 24 and was even higher for those with incomplete elementary education (approximately 11%). In the North and Northeast regions of the country, this expenditure exceeded 9%. The state with the most significant impact on household income was Acre (13.6%), followed by Alagoas (11.9%), Ceará, Pará, and Tocantins (all with approximately 11%). Our findings, therefore, reinforce the importance of strengthening the implementation of effective measures, such as tax policy, to reduce the proportion of smokers. Thus, the money that individuals currently allocate to purchase cigarettes can be used to meet their basic needs, contributing to the promotion of health and improving the quality of life.

Em um Brasil no qual os indicadores de empobrecimento da população seguem aumentando, preocupa o fato de que indivíduos gastem dinheiro para comprar cigarro em vez de usarem esse recurso em ações que fortaleçam aspectos do bem-estar de suas jornadas de vida e de suas famílias. Estimou-se, a partir da Pesquisa Nacional de Saúde de 2019, a influência que o gasto com cigarro industrializado teve no orçamento familiar nos domicílios com pelo menos um fumante, estratificada por características sociodemográficas. Os fumantes brasileiros destinaram cerca de 8% do rendimento médio mensal domiciliar per capita para a compra de cigarros industrializados. O percentual do gasto médio mensal chegou a quase 10% desse rendimento, entre os fumantes de 15 a 24 anos, e foi ainda maior para aqueles com Ensino Fundamental incompleto (aproximadamente 11%). Nas regiões Norte e Nordeste do país, esse gasto ultrapassou os 9%. O estado com o maior comprometimento da renda domiciliar foi o Acre (13,6%), seguido por Alagoas (11,9%), Ceará, Pará e Tocantins (todos com aproximadamente 11%). Nossos achados reforçam, portanto, a importância de fortalecer a implementação de medidas efetivas de redução da proporção de fumantes, tal como a política tributária. Dessa forma, o dinheiro que atualmente é destinado pelos indivíduos à compra de cigarros poderá ser revertido no atendimento de suas necessidades básicas, contribuindo para a promoção da saúde e melhoria da qualidade de vida.

En un Brasil donde los indicadores de empobrecimiento de la población siguen aumentando, es preocupante el hecho de que las personas gasten dinero para comprar cigarrillo en lugar de usarlo en acciones para fortalecer los aspectos del bienestar de sus vidas y la de sus familias. A partir de la Encuesta Nacional de Salud brasileña realizada en 2019, se estimó la influencia del gasto en cigarrillo industrializado en el presupuesto familiar de los hogares donde vivía al menos un fumador, estratificado por características sociodemográficas. Los fumadores brasileños destinaron alrededor del 8% del ingreso per cápita mensual promedio del hogar para la compra de cigarrillos industrializados. El porcentaje del gasto mensual promedio en cigarrillos alcanzó casi el 10% de este ingreso entre los fumadores de 15 a 24 años y fue aún mayor para los que tenían educación primaria incompleta (aproximadamente el 11%). En el Norte y Nordeste del país, ese gasto superó el 9%. El estado con un mayor compromiso con los ingresos del hogar fue Acre (el 13,6%), seguido por Alagoas (el 11,9%), Ceará, Pará y Tocantins (todos con aproximadamente el 11%). Por lo tanto, nuestros resultados resaltan la importancia de fortalecer la implementación de medidas efectivas para reducir la proporción de fumadores, tal como la política tributaria. Así, el dinero que actualmente las personas destinan a la compra de cigarrillos podría utilizarse en la atención de sus necesidades básicas, contribuyendo a promover la salud y la mejora de la calidad de vida.

Racial disparities in breast cancer survival after treatment initiation in Brazil: a nationwide cohort study.

BACKGROUND: Breast cancer is a public health priority in Brazil and ensuring equity in health care is one of the cancer control plan goals. Our aim was to present the first assessment on the influence of race or skin colour on breast cancer survival at the national level. METHODS: In this nationwide cohort study, data on women who initiated treatment for breast cancer in the public health-care system (Sistema Unico de Saúde), Brazil, were assembled through record linkage of administrative and mortality information systems. The administrative information systems were the Outpatient Information System (data from high complexity procedure authorisations) and the Hospital Information System (data from hospitalisation authorisations). We included women aged 19 years or older who started treatment between Jan 1, 2008, and Nov 30, 2010; self-identified as having White, Black, or Brown race or skin colour; had tumour stage I-IV; and were treated with chemotherapy or radiotherapy, or both. Patients were followed up until Dec 31, 2015. Patients with only hormone therapy records or who underwent only surgery were excluded. The Kaplan-Meier method was used to estimate crude overall survival for race or skin colour by time since treatment initiation, and Cox regression to estimate all-cause mortality hazard ratios (HRs) before and after adjustment for other covariates. FINDINGS: We identified 59 811 women treated for stage I-IV breast cancer. 37 318 (62·4%) women identified themselves as White, 18 779 (31·4%) as Brown, and 3714 (6·2%) as Black. 5-year overall survival probability was higher for White women (74% [95% CI 73-74]) than Black women (64% [62-65]; p<0·0001). In adjusted regression models stratified by the absence of hormone therapy, Black women had a 24% (HR 1·24 [95% CI 1·16-1·34]; p<0·0001) higher risk of all-cause death than White women, and in the presence of hormone therapy Black women had a 25% (1·25 [1·14-1·38]; p<0·0001) higher risk of all-cause death than White women. INTERPRETATION: Black skin colour was identified as a statistically significant risk marker for lower 5-year survival probability and higher risk of all-cause death among women treated for breast cancer by the Sistema Unico de Saúde. Actions to understand and mitigate this unfair difference in health results are urgently needed.

Impact of microvascular invasion on 5-year overall survival of resected non-small cell lung cancer.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is an incidental and aggressive type of cancer. Although curative treatment can be offered, the recurrence rate is relatively high. Identifying factors that have a prognostic impact may guide changes in the staging system and recommendations for adjuvant therapy. The aim of this study was to evaluate the impact of microvascular invasion on the 5-year overall survival (OS) of patients with resected NSCLC treated at a reference cancer center. METHODS: This retrospective, observational cohort study included patients diagnosed with early-stage NSCLC (clinical stages I-IIIA), treated with curative-intent surgery at the Brazilian National Cancer Institute between 2010 and 2016. RESULTS: The dataset comprised 91 surgical patients, mostly females and white, with a mean age of 62 years (range between 29-83). Cases were distributed as stages I, II, and III in 55%, 29%, and 16%. Adenocarcinoma was the predominant histological subtype (67%), and microvascular invasion was present in 25% of the patients. The 5-year OS probability was 60% (95% CI, 48.3-68.9). Among all characteristics, advanced stages (p = 0.001) and the presence of microvascular invasion (p< 0.001) were related to a worse 5-year OS. After adjusting for age group and pathological stage, the presence of microvascular invasion was associated with a 4-fold increased risk of death (HR 3.9, 95% CI, 1.9-8.2). CONCLUSION: The presence of microvascular invasion was an independent factor related to worse survival and, therefore, should be routinely assessed in resected specimens.

"Tobacco denormalization at home": the contribution of the smoking ban in enclosed workplaces in Brazil.

Estimates suggest that exposure to environmental tobacco smoke is related to 1.2 million deaths per year worldwide. Synergy between various anti-smoking legislative and educational measures is essential to stimulate cessation and prevent initiation. This article aimed to explore how legislative protection from exposure to environmental tobacco smoke in enclosed workplaces in Brazil, whose strengthening occurred in a phased manner between 1996 and 2014, possibly contributed to the protection from passive smoking at home. We evaluated, via generalized linear models, the absolute and relative differences in the proportion of individuals living in smoke-free homes between those exposed and not exposed to passive smoking in enclosed workplaces, both crude and adjusted by sociodemographic and smoking behavior variables, and stratified by non-smokers and smokers. Data from three national surveys conducted in 2008, 2013, and 2019 were used. Regardless of smoking status and year when the data were analyzed, individuals who were employed in smoke-free workplaces were more likely to live in smoke-free homes than smokers who were employed in workplaces that allowed smoking. Adjusted absolute difference increased from +5.5% in 2008 to +10.5% in 2013 among non-smokers, and from +7.1% in 2013 to 15.6% in 2019 among smokers (p-values for additive interaction ≤ 0.05). Strengthening the Brazilian smoke-free legislation was likely associated with a reduction in passive smoking at home, which, therefore, may also reduce the burden of mortality, morbidity, and costs for society related to smoking.

[Prevalence and factors associated to advanced stage breast cancer diagnosis]. / Prevalência e fatores associados ao diagnóstico de câncer de mama em estágio avançado.

This cross-sectional study investigated the prevalence and factors associated with advanced stage breast cancer diagnosis among 18,890 women assisted in a specialized hospital in the capital of Rio de Janeiro, Brazil, from 1999 to 2016. We used Poisson regression with robust variance to estimate prevalence ratios and respective 95% confidence intervals. The highest prevalence of diagnosis in this condition was in women aged 20-39 and 40-49 years, black and brown, living without a partner, from other cities of the state of Rio de Janeiro, who were referred by the Unified Health System and diagnosed in the 1999-2004 and 2005-2010 six-year periods. On the other hand, women aged 60-69 and 70-99 years, with some schooling level, with a family history of cancer and who arrived at the hospital with diagnosis and without treatment had lower prevalence of advanced stage breast cancer diagnosis. These results can be considered when planning secondary prevention actions to anticipate and, thus, collaborate to reduce the prevalence the breast cancer diagnosis in the most vulnerable groups.

Este estudo transversal investigou a prevalência e os fatores associados ao diagnóstico de câncer de mama em estágio avançado entre 18.890 mulheres assistidas em hospital especializado da capital do Rio de Janeiro, Brasil, entre os anos 1999 e 2016. Utilizou-se regressão de Poisson com variância robusta para estimar razões de prevalência e respectivos intervalos de 95% de confiança. Apresentaram maiores prevalências de diagnóstico nessa condição mulheres com idade entre 20-39 e 40-49 anos, de raça/cor da pele preta e parda, que viviam sem companheiro(a), procedentes de outros municípios do estado do Rio de Janeiro, que tiveram o Sistema Único de Saúde como origem do encaminhamento e que foram diagnosticadas nos sexênios 1999-2004 e 2005-2010. Em contrapartida, mulheres com idade entre 60-69 e 70-99 anos, que cursaram algum nível de escolaridade, com histórico familiar de câncer e que chegaram ao hospital com diagnóstico e sem tratamento apresentaram menores prevalências de diagnóstico em estágio avançado. Esses resultados podem ser considerados no planejamento de ações de prevenção secundária, a fim de antecipar o diagnóstico de câncer de mama dos grupos mais vulneráveis e assim colaborar para a redução da prevalência do diagnóstico em estágio avançado.

Estima-se que a exposição à fumaça ambiental de tabaco esteja relacionada a 1,2 milhão de mortes por ano no mundo. A sinergia das diversas medidas antitabaco, tanto legislativas quanto educativas, é essencial para estimular a cessação e prevenir a iniciação do tabagismo. O artigo tem como objetivo explorar a possível contribuição da proteção legislativa contra a exposição à fumaça ambiental de tabaco nos locais fechados de trabalho no Brasil, cujo fortalecimento ocorreu por fases entre 1996 e 2014, para a proteção contra o tabagismo passivo em casa. Foram utilizados modelos lineares generalizados para avaliar as diferenças absolutas e relativas na proporção de brasileiros que vivem em domicílios sem fumaça ambiental de tabaco, entre aqueles expostos e não expostos ao tabagismo passivo em locais de trabalho fechados, brutas e ajustadas por variáveis sociodemográficas e de comportamento de tabagismo, estratificadas entre fumantes e não fumantes. Foram usados os dados de três inquéritos nacionais, realizados em 2008, 2013 e 2019. Independentemente de condição de tabagista e do ano de análise, os indivíduos empregados em locais de trabalho livres de tabaco apresentaram maior probabilidade de residir em domicílios livres de tabaco, comparado com aqueles que trabalhavam em locais onde fumar era permitido. A diferença absoluta ajustada aumentou de +5,5% em 2008 para +10,5% em 2013 entre não fumantes, e de +7,1% em 2013 para +15,6% em 2019 entre fumantes (valores de p de interação aditiva ≤ 0,05). É provável que o fortalecimento da legislação antitabaco no Brasil esteve associado a uma redução no tabagismo passivo em casa, o que, portanto, pode reduzir a carga de morbimortalidade e de custos para a sociedade, relacionados ao tabagismo.

Se estimó que la exposición al humo del tabaco ambiental está relacionada con 1,2 millones de muertes por año en todo el mundo. La sinergia de varias medidas antitabaco legislativas y educacionales es esencial para estimular dejar de fumar y prevenir comenzar a fumar. La propuesta de este artículo fue explorar la posible contribución de la protección legislativa ante la exposición al humo del tabaco ambiental en lugares de trabajo cerrados en Brasil, cuyo afianzamiento se produjo de manera gradual entre 1996 y 2014, para la protección de los fumadores pasivos en casa. Se utilizaran modelos lineales generalizados para evaluar las diferencias absolutas y relativas en la proporción de individuos que viven en hogares libres de humos, entre quienes estaban expuestos y no expuestos como fumadores pasivos en lugares de trabajo cerrados, crudas y ajustadas por variables sociodemográficas y comportamiento de fumador, y estratificadas por no fumadores y fumadores. Se usaron los datos de las tres encuestas nacionales llevadas a cabo en 2008, 2013 y 2019. Independientemente del estatus del consumo de tabaco y el año de análisis, los individuos que fueron empleados en un lugar de trabajo libre de humos tenían más probabilidades de vivir en un hogar libre de humos en comparación con los fumadores que trabajaban en donde se fumaba. La diferencia ajustada absoluta aumentó del +5,5% en 2008 al +10,5% en 2013 entre no fumadores, y del +7,1% en 2013 al +15,6% en 2019 entre fumadores (valores de p de interacción aditiva ≤ 0,05). El fortalecimiento de la legislación antitabaco en Brasil estuvo presumiblemente asociado con una reducción con los fumadores pasivos en el hogar, y, por consiguiente, podría también reducir la carga de mortalidad, morbilidad y costes para la sociedad en relación con el tabaquismo.

Impact of microvascular invasion on 5-year overall survival of resected non-small cell lung cancer / Impacto da invasão microvascular na sobrevida global em 5 anos do câncer de pulmão não pequenas células ressecado

RESUMO Objetivos: O câncer de pulmão não pequenas células (CPNPC) é um tipo incidental e agressivo de câncer. Embora o tratamento curativo possa ser oferecido, a taxa de recidiva é relativamente alta. A identificação de fatores que têm impacto prognóstico pode orientar mudanças no TNM e recomendações para terapia adjuvante. O objetivo deste estudo foi avaliar o impacto da invasão microvascular na sobrevida global (SG) em 5 anos de pacientes com CPNPC ressecado tratados em um centro de referência em câncer. Métodos: Este estudo de coorte retrospectivo e observacional incluiu pacientes diagnosticados com CPNPC em estágio inicial (estágios clínicos I-IIIA), tratados com cirurgia com intenção curativa no Instituto Nacional de Câncer entre 2010 e 2016. Resultados: Foram incluídos 91 pacientes tratados com cirurgia, a maioria mulheres e brancos, com média de idade de 62 anos (variação entre 29-83). Os casos foram distribuídos em estágios I, II e IIIA em 55%, 29% e 16%. Adenocarcinoma foi o subtipo histológico predominante (67%), e a invasão microvascular esteve presente em 25% dos pacientes. A probabilidade de SG em 5 anos foi de 60% (IC 95%, 48,3-68,9). Dentre todas as características analisadas, estágios mais avançados (p = 0,001) e a presença de invasão microvascular (p < 0,001) foram relacionados a uma pior SG em 5 anos. Após ajustar para faixa etária e estágio patológico, a presença de invasão microvascular foi associada a um aumento de 4 vezes no risco de morte (RR 3,9, IC 95%, 1,9-8,2). Conclusão: A presença de invasão microvascular foi um fator independente relacionado a uma pior sobrevida e, portanto, deve ser avaliada rotineiramente em espécimes ressecados.

The highest prevalence of diagnosis in this condition was in women aged 20-39 and 40-49 years, black and brown, living without a partner, from other cities of the state of Rio de Janeiro, who were referred by the Unified Health System and diagnosed in the 1999-2004 and 2005-2010 six-year periods. On the other hand, women aged 60-69 and 70-99 years, with some schooling level, with a family history of cancer and who arrived at the hospital with diagnosis and without treatment had lower prevalence of advanced stage breast cancer diagnosis. These results can be considered when planning secondary prevention actions to anticipate and, thus, collaborate to reduce the prevalence the breast cancer diagnosis in the most vulnerable groups.

[Risk of initiation to smoking with the use of electronic cigarettes: systematic review and meta-analysis]. / Risco de iniciação ao tabagismo com o uso de cigarros eletrônicos: revisão sistemática e meta-análise.

This article aims to evaluate the association between the use of electronic cigarettes and initiation to smoking, through a systematic review with meta-analysis of longitudinal studies. A bibliographic search was performed on the MEDLINE, Embase, LILACS and PsycInfo databases. Reference selection, data extraction and risk of bias assessment of the studies were independently carried out in pairs, and the disagreements were discussed with a third researcher to reach a consensus. Meta-analysis was performed using the Mantel-Haenszel random effects model. Among the 25 studies included, 22 evaluated the outcome of conventional cigarette experimentation and nine assessed the outcome of current smoking (in the last 30 days). The meta-analysis showed that the use of electronic cigarettes increased the risk of conventional cigarette experimentation by almost three and a half times (RR=3.42; 95%CI 2.81-4.15), and by more than four times the risk of current smoking (RR=4.32; 95%CI 3.13-5.94). The risk of smoking initiation is significantly higher among electronic cigarette users. The marketing authorization of such devices may represent a threat to public health policies in Brazil.

O objetivo deste artigo é avaliar a associação entre uso de cigarros eletrônicos e iniciação ao tabagismo, por meio de uma revisão sistemática com meta-análise de estudos longitudinais. Busca bibliográfica foi realizada nas bases MEDLINE, Embase, LILACS e PsycInfo. As etapas de seleção de referências, extração dos dados e avaliação do risco de viés dos estudos foi realizada em dupla, de forma independente e as divergências discutidas com um terceiro pesquisador para obtenção de consenso. Meta-análise foi realizada por meio do modelo Mantel-Haenszel de efeitos aleatórios. Dentre os 25 estudos incluídos, 22 avaliaram o desfecho de experimentação de cigarro convencional e nove avaliaram o desfecho de tabagismo atual (nos últimos 30 dias). A meta-análise demonstrou que o uso de cigarro eletrônico aumentou em quase três vezes e meia o risco de experimentação de cigarro convencional (RR=3,42; IC95% 2,81-4,15) e em mais de quatro vezes o risco de tabagismo atual (RR=4,32; IC95% 3,13-5,94). O risco de iniciação ao tabagismo é significativamente maior entre usuários de cigarro eletrônico. A liberação da comercialização desses dispositivos pode representar uma ameaça para as políticas de saúde pública no Brasil.

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: where are we going?

OBJECTIVE: To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. METHODS: We used data from the 2019 National Health Survey to estimate the prevalence of lifetime and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the III Brazilian Household Survey on Substance Use-2015 and the National Health Survey-2013. RESULTS: For 2019, the prevalence of current use of ENDS was estimated at 0.64% (∼1 million people), of which ∼70% were in the age group of 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast region concentrates half of these users. Almost 90% are non-smokers, with high prevalence among those who also use waterpipe and abuse alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (∼800,000 individuals), of which ∼80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ∼300%. CONCLUSIONS: In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of ENDS and waterpipe has been increasing even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: Where are we going? / Prevalência de uso de dispositivos eletrônicos para fumar e de uso de narguilé no Brasil: Para onde estamos caminhando?

Objective: To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. Methods: We used data from the 2019 National Health Survey (PNS) to estimate the prevalence of ever and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the BHSU-III-2015 (III Brazilian Household Survey on Substance Use) and the PNS-2013. Results: For 2019, the prevalence of current use of ENDS was estimated at 0.64% (~ 1 million people), of which ~70% were 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast concentrates half of these users. Almost 90% are non-smokers, and higher prevalence were found among those who also use waterpipe and abusive alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (~ 800,000 individuals), of which ~80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ~300%. Conclusions: In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of DEF and waterpipe has been increasing, even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

Objetivo: Descrever as prevalências de uso de dispositivos eletrônicos para fumar (DEF) e de narguilé no Brasil, por subgrupos populacionais, e avaliar tendência entre 2013 e 2019. Métodos: Os dados principais analisados são da Pesquisa Nacional de Saúde (PNS) de 2019. Estimou-se prevalências de uso na vida e atual de DEF e de uso atual de narguilé segundo características sócio-comportamentais. Os dados da PNS-2019 sobre DEF foram comparados aos do III-LNUD-2015 (III Levantamento Nacional sobre Uso de Drogas pela População Brasileira) e os dados sobre narguilé comparados à PNS-2013. Resultados: Para 2019, estimou-se a prevalência de uso atual de DEF em 0,64% (~1 milhão de pessoas), dos quais ~70% tinham 15-24 anos. Maior prevalência está na região Centro-Oeste, mas o Sudeste concentra metade absoluta desses usuários. Quase 90% são não fumantes, e maiores prevalências foram encontradas entre quem usa também narguilé e álcool abusivo. Observou-se aumento nas estimativas de uso de DEF entre 2015 e 2019, especialmente entre os mais jovens. A prevalência de uso atual de narguilé em 2019 foi estimada em 0,47% (~800 mil indivíduos), dos quais ~80% tinham 15-24 anos. Houve aumento na prevalência de uso atual de narguilé entre 2013 e 2019, e entre jovens o aumento foi de ~300%. Conclusões: No Brasil os DEF têm sido utilizados majoritariamente por jovens, e por nunca fumantes de cigarros industrializados. O uso de DEF e de narguilé vêm aumentando, mesmo com as restrições regulatórias do país, podendo comprometer o exitoso histórico da política de controle do tabagismo.

Food Profiles of Indigenous Households in Brazil: Results of the First National Survey of Indigenous Peoples' Health and Nutrition.

The objective of the present study was to characterize the food profiles in Indigenous households participating in the First National Survey of Indigenous People's Health and Nutrition in Brazil. Multiple correspondence analysis was used to estimate distances between regions and foods from three sources (local Indigenous production, purchased, and external donation), in addition to "not consumed." The combined distribution of the first two dimensions revealed three distinct profiles of food acquisition. Observed proximities between geopolitical regions and distinct modes of food acquisition speak to regional contrasts in food sovereignty among the Indigenous population that are closely linked to historical occupation and economic expansion in the country. Considering the concept of food sovereignty as involving rights to dietary autonomy, healthy diets, and resource management, our data suggest Brazil's North region is the closest of the four regions analyzed to these goals. Food sovereignty in the Northeast and South/Southeast regions is reduced due to greater monetarization and proximity to market economy resources. The advance of agribusiness in the Amazon has been a hallmark of the Brazilian government's current environmental policy, directly threatening the survival of Indigenous peoples living in that region.

Birth weight of indigenous children in Brazil: results of the First National Survey of Indigenous People's Health and Nutrition.

Birth weight is an important predictor of perinatal, infant, and preschool-age children morbimortality. However, information about indigenous children's birth weight is still scarce. This study aimed to analyze the birth weight of indigenous children based on data from the First National Survey of Indigenous People's Health and Nutrition, Brazil (2008-2009). This is the first study to address indigenous children's birth weight based on a nationwide representative sample. Mean birth weights and the respective standard deviations were calculated according to geopolitical region, sex, type of birth, and birthplace. The chi-square test was used to analyze differences in proportions, and Kruskal-Wallis and Mann-Whitney U tests in means, considering sample design and data normality. We found no records on birth weight in the researched documents for 26.7% of the 6,128 sampled children. The mean birth weight for the 3,994 children included in the analyses was 3,201g (standard deviation - SD ± 18.6g), regardless of sex, type of birth, and birthplace. The prevalence of low birth weight was 7.6% (n = 302) and was significantly higher among girls. Boys presented significantly higher mean birth weight than girls, regardless of the geopolitical region. Low birth weight was slightly less frequent among indigenous children when compared to Brazilian children in general. Our study indicates the need to improve prenatal care and the quality of consultation records for indigenous women as a strategy to promote safe pregnancy and childbirth.

O peso ao nascer é um importante preditor de morbimortalidade perinatal, infantil e pré-escolar. São escassas as informações sobre o peso ao nascer das crianças indígenas no Brasil. O estudo teve como objetivo analisar o peso ao nascer das crianças indígenas, com base nos dados do Primeiro Inquérito Nacional de Saúde e Nutrição dos Povos Indígenas, Brasil (2008-2009). Este é o primeiro estudo a avaliar o peso ao nascer de crianças indígenas com base em uma amostra nacional representativa. Foram calculadas as médias e desvios-padrão de acordo com macrorregião, sexo, tipo e parto e local do parto. Foram utilizados o teste de qui-quadrado para analisar as diferenças de proporções e os testes de Kruskal-Wallis e U de Mann-Whitney para diferenças nas médias, considerando o desenho amostral do estudo e a normalidade dos dados. Para 26,7% das 6.128 crianças da amostra, não foi possível localizar qualquer registro de peso ao nascer nos documentos consultados. Entre as 3.994 crianças incluídas nas análises, o peso médio ao nascer, independentemente de sexo, tipo de parto e local do parto, foi 3.201g (desvio padrão - DP ± 18,6g). A prevalência de baixo peso ao nascer foi 7,6% (n = 302), significativamente mais alta em meninas. Os meninos apresentaram peso médio ao nascer significativamente mais alto que as meninas, independentemente de região. A frequência de baixo peso ao nascer foi ligeiramente mais baixa que nas crianças brasileiras em geral. O estudo aponta para a necessidade de melhorar a assistência pré-natal e a qualidade dos registros das consultas das mulheres indígenas, como estratégia para promover a segurança na gravidez e no parto.

Para un 26,7% de los 6.128 niños incluidos en la muestra no fue posible localizar ningún registro de peso al nacer en los documentos investigados. De los 3.994 niños incluidos en el análisis, la media de peso al nacer, independiente del sexo, tipo de nacimiento, y lugar de nacimiento, fue 3.201g (desviación estándar - SD ± 18,6g). La prevalencia del bajo peso al nacer fue 7,6% (n = 302) y fue significativamente más alta entre niñas. Los niños presentaron significativamente una media más alta de peso al nacer que las niñas, independientemente de la región. La frecuencia del bajo peso al nacer fue ligeramente más baja que la observada en niños brasileños en general. Este estudio presenta aspectos que se necesitan mejorar en el cuidado prenatal y en la calidad de los registros de las consultas de mujeres indígenas, como una estrategia para promover un embarazo y parto seguros.

Assessing trends of breast cancer and carcinoma in situ to monitor screening policies in developing settings.

There have been arguments about the role of breast cancer screening at the population level, and some points of controversy have arisen, such the establishment of organized screening policies and the age at which to begin screening. The real benefit of screening has been questioned because the results of this practice may increase the diagnosis of indolent lesions without decreasing mortality due to breast cancer. The authors have proposed a study of incidence and mortality trends for breast cancer in a developing setting in Brazil to monitor the effectiveness of the official recommendations that prioritize the age group from 50 to 69 years. The database of the Cancer Registry and the Mortality Information System was used to calculate age-standardized and age-specific rates, which were then used to calculate incidence and mortality trends using the Joinpoint Regression Program. The results showed stability in trends across all ages and age-specific groups in both incidence and mortality. In conclusion, we found that incidence and mortality rates are compatible with those in regions with similar human development indexes, and trends have demonstrated stabilization. Thus, we do not endorse changes in the official recommendations to conduct screening for ages other than 50 to 69 years, nor should policy makers implement organized screening strategies.
