Description of vaccination coverage and hesitancy obtained by epidemiological survey of children born in 2017-2018, in Belo Horizonte and Sete Lagoas, Minas Gerais, Brazil.

OBJECTIVE: To describe vaccination coverage and hesitation for the basic children's schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil. METHODS: Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy. RESULTS: Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy. CONCLUSION: Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities. MAIN RESULTS: Vaccination coverage of children up to 4 years old was 50.2% in Belo Horizonte, and 64.9% in Sete Lagoas. Fear of severe reactions and believing that vaccination against eradicated diseases is unnecessary were the main reasons for vaccination hesitancy. IMPLICATIONS FOR SERVICES: Recovery of high vaccination coverage among children, considering public health service access conditions and socioeconomic inequities. Acting on reasons for hesitancy that can assist in targeting actions. PERSPECTIVES: The multifactorial context of vaccination hesitancy demands the development of health education strategies to raise awareness about child immunization.

Spatial clusters and social inequities in COVID-19 vaccine coverage among children in Brazil.

This study examined the spatial distribution and social inequalities in COVID-19 vaccine coverage among children aged 5-11 in Brazil. First and second dose vaccine coverage was calculated for all Brazilian municipalities and analyzed by geographic region and deciles based on human development index (HDI-M) and expected years of schooling at 18 years of age. Multilevel models were used to determine the variance partition coefficient, and bivariate local Moran's I statistic was used to assess spatial association. Results showed significant differences in vaccine coverage rates among Brazilian municipalities, with lower coverage in the North and Midwest regions. Municipalities with lower HDI and expected years of schooling had consistently lower vaccine coverage rates. Bivariate clustering analysis identified extensive concentrations of municipalities in the Northern and Northeastern regions with low vaccine coverage and low human development, while some clusters of municipalities in the Southeast and South regions with low coverage were located in areas with high HDI-M. These findings highlight the persistent municipal-level inequalities in vaccine coverage among children in Brazil and the need for targeted interventions to improve vaccine access and coverage in underserved areas.

Resumo O estudo analisou a distribuição espacial e as desigualdades sociais na cobertura vacinal para COVID-19 entre crianças de 5 a 11 anos no Brasil. As coberturas vacinais foram calculadas para os municípios brasileiros e analisadas por região geográfica e decis com base no Índice de Desenvolvimento Humano (IDH-M) e expectativa de escolaridade aos 18 anos. Modelos multiníveis foram usados ​​para determinar o coeficiente de partição da variância, e a estatística local bivariada de Moran I foi usada para avaliar a associação espacial. Os resultados mostraram diferenças significativas nas taxas de cobertura vacinal entre os municípios, com menor cobertura nas regiões Norte e Centro-Oeste. Municípios com menor IDH e anos de escolaridade esperados apresentaram menores taxas de cobertura vacinal. A análise de agrupamento bivariado identificou extensas concentrações de municípios nas regiões Norte e Nordeste com baixa cobertura vacinal e baixo desenvolvimento humano, enquanto alguns aglomerados de municípios nas regiões Sudeste e Sul com baixa cobertura localizavam-se em áreas com alto IDH-M. Essas descobertas destacam as desigualdades persistentes em nível municipal na cobertura vacinal entre crianças e a necessidade de intervenções para melhorar o acesso e a cobertura vacinal em áreas mais vulneráveis.

Racial inequalities in child vaccination and barriers to vaccination in Brazil among live births in 2017 and 2018: an analysis of a retrospective cohort of the first two years of life.

OBJECTIVE: To describe timely vaccination completion and obstacles in the first 24 months of life in Brazil, examining associations with maternal race/skin color. METHODS: Study participants were 37,801 children born in 2017 and 2018 included in the National Immunization Coverage Survey. We calculated prevalence and 95% confidence intervals for timely vaccine completeness and obstacles at 5, 12 and 24 months of life, according to maternal race/skin color. Associations were analyzed using logistic regression. RESULTS: 7.2% (95%CI 6.3;8.2) of mothers faced difficulties in taking their children to be vaccinated, and 23.4% (95%CI 21.7;25.1) were not vaccinated when taken. These proportions were 75% (95%CI 1.25;2.45) and 97% (95%CI 1.57;2.48) higher, respectively, among Black mothers. At least one vaccination was delayed among 49.9% (95%CI 47.8;51.9) and 61.1% (95%CI 59.2;63.0) of children by 5 and 12 months, respectively. These rates were higher among Black/mixed race mothers. CONCLUSION: There are racial inequalities in both the obstacles faced and in vaccination rates in Brazil. MAIN RESULTS: Marked racial inequalities were found in the obstacles to vaccination of children under 24 months in Brazil and to timely vaccination at 5 months and in the first year of life. IMPLICATIONS FOR SERVICES: Racial inequalities in the occurrence of vaccination shortcomings in health services, in the objective restrictions faced by families in taking their children to vaccination centers and in incomplete vaccination in a timely manner need to be addressed by the Brazilian National Health System. PERSPECTIVES: Equal public policies to address barriers to vaccination and qualification of health services need to be implemented. Studies need to deepen understanding of the structural determinants that lead to racial disparities.

Increasing primary care capacity and referral efficiency: A case study of a telehealth centre eConsult service in Brazil.

INTRODUCTION: eConsults are asynchronous digital communications for primary care professionals to seek timely specialist advice. Potential benefits include increased primary healthcare capacity and referral efficiency. Santa Catarina Telehealth Centre in Brazil has offered eConsults for an increasing number of specialties since 2008. This study described the characteristics of this service, including referral efficiency, sustainability, and satisfaction. METHODS: Retrospective longitudinal analysis of eConsults activity data from 2015 to 2022 with three domains of the Model for Assessment of Telemedicine Applications used to structure the analysis. RESULTS: Characteristics of the application: The total number of eConsults performed in 2015 was 4764, reaching 41,178 in 2022. While 30.3% of eConsults were synchronous in 2015, only asynchronous communication remained from 2021. Clinical effectiveness: eConsults requested to refer patients to specialist care resulting in primary care management remaining above 30% of the total for all specialties from 2019 to 2022, with hematology having the highest percentage (>52%). Organizational aspects: Established workflows with local specialists responding to eConsults (cardiology, endocrinology, hematology and orthopaedics) kept a constant or increasing number of eConsults and maintained the proportion of primary care management from 2019 to 2022, once recovered from COVID-19 and funding restrictions-related reductions. Over 90% of primary care professionals are either satisfied or very satisfied with the eConsult service. CONCLUSION: Over 8 years, 223,734 consultations were conducted, with high satisfaction, demonstrating the substantial potential for increased primary care-sensitive conditions management. Hiring local specialists, fostering integrated care, and enabling sustainable workflows are key to eConsults' success.

Life course social mobility, race and tooth loss in adulthood: The role of dental health services.

OBJECTIVES: To evaluate the extent to which dental care factors in adulthood modify and, at the same time, mediate the association between race/ethnicity and social mobility from childhood to adulthood with two oral health outcomes in adults. METHODS: In 2012, 1222 individuals 20-59 years old participated in the second wave of the Epi-Floripa Study in Florianopolis, Brazil. Exposures included social mobility based on adulthood and childhood events, dental care in previous years, type of dental care coverage, reason for dental visits and race. The number of missing and decayed teeth were dichotomised as MT >0 and DT >0. RESULTS: The prevalence of missing and decayed teeth was 61.9% and 23.0%, respectively. Age-sex adjusted inequalities in decayed and missing teeth among Black and White individuals were 41.2 percentage points (pp) (95% CI: 3.9-78.7) and 53.1 pp (19.5:86.7), respectively. Inequalities between those persistently higher and lower in socioeconomic position were 42.6 pp (14.6-70.7) and 90.0 pp (62.1-100). The Relative Excess of Risk due to Interaction (RERI) was not statistically significant (p < 0.05). Oaxaca-Blinder decomposition analyses showed that dental care variables accounted for a small proportion of inequalities. CONCLUSIONS: This result implies that dental care is unlikely to significantly reduce or increase oral health inequalities in this particular population.

The Brazilian vaccine divide: How some municipalities were left behind in the Covid-19 vaccine coverage.

This study aims to assess the progress of geographic, socioeconomic, and demographic disparities in Covid-19 vaccination coverage in Brazil over the first two years of the vaccination campaign. Data from the National Immunization Program Information System were used to estimate covid-19 vaccine coverage. Brazilian municipalities were divided into two groups based on their vaccine coverage for the booster dose. The first group comprised 20% of municipalities with the lowest coverage, while the second group (80% of municipalities) had higher coverage. The analysis was conducted separately for four age groups: 5-11, 12-17, 18-59, and 60+. Explanatory variables included socioeconomic and health services indicators. Crude and adjusted logistic regression models were used to estimate the probability of a municipality being among those with the worst vaccination coverage according to the categories of exploratory variables. Between January/2021 and December/2022, Brazil administered 448.2 million doses of the covid-19 vaccine. The booster vaccination coverage varied from 24.8% among adolescents to 79.7% among the elderly. The difference between the group with the highest and lowest coverage increased during the national vaccination campaign. Municipalities with lower education levels, higher proportion of Black population, higher Gini index, and worse health service indicators had a greater likelihood of having lower vaccination coverage. High and increasing levels of inequality in Covid-19 vaccination were observed in Brazil across all age groups during the vaccination campaign in 2021-2022.

National Vaccine Coverage Survey 2020: methods and operational aspects.

OBJECTIVE: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. METHODS: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. RESULTS: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. CONCLUSION: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

Uncovering inequities in Covid-19 vaccine coverage for adults and elderly in Brazil: A multilevel study of 2021-2022 data.

Vaccination is crucial for reducing severe COVID-19 cases, hospitalizations, and deaths. However, vaccine access disparities within countries, particularly in low- and middle-income nations, may leave disadvantaged regions and populations behind. This study aimed to investigate potential inequalities in vaccine coverage among Brazilian aged 18 years and older based on demographic, geographic, and socioeconomic characteristics at the municipal level. A total of 389 million vaccination records from the National Immunization Program Information System were analyzed to calculate vaccine coverage rates for the first, second, and booster doses among adults (18-59 years) and elderly (60 + years) vaccinated between January 2021 and December 2022. We analyzed the data by gender and used a three-level (municipalities, states, regions) multilevel regression analysis to assess the association between vaccine coverage and municipal characteristics. Vaccination coverage was higher among the elderly than among adults, particularly for the second and booster doses. Adult women showed higher coverage rates than men (ranging from 118 % to 25 % higher along the analyzed period). Significant inequalities were observed when analyzing the evolution of vaccination coverage by sociodemographic characteristics of municipalities. In the early stages of the vaccination campaign, municipalities with higher per capita Gross Domestic Product (pGDP), educational level, and fewer Black residents reached higher population coverages earlier. In December 2022, adult and elderly booster vaccine coverage was 43 % and 19 %, respectively, higher in municipalities in the highest quintile of educational level. Higher vaccine uptake was also observed in municipalities with fewer Black residents and higher pGDP. Municipalities accounted for most of the variance in vaccine coverage (59.7 %-90.4 % depending on the dose and age group). This study emphasizes the inadequate booster coverage and the presence of socioeconomic and demographic disparities in COVID-19 vaccination rates. These issues must be addressed through equitable interventions to avoid potential disparities in morbidity and mortality.

Genomic Surveillance of SARS-CoV-2 in Healthcare Workers: A Critical Sentinel Group for Monitoring the SARS-CoV-2 Variant Shift.

SARS-CoV-2 genome surveillance is important for monitoring risk groups and health workers as well as data on new cases and mortality rate due to COVID-19. We characterized the circulation of SARS-CoV-2 variants from May 2021 to April 2022 in the state of Santa Catarina, southern Brazil, and evaluated the similarity between variants present in the population and healthcare workers (HCW). A total of 5291 sequenced genomes demonstrated the circulation of 55 strains and four variants of concern (Alpha, Delta, Gamma and Omicron-sublineages BA.1 and BA.2). The number of cases was relatively low in May 2021, but the number of deaths was higher with the Gamma variant. There was a significant increase in both numbers between December 2021 and February 2022, peaking in mid-January 2022, when the Omicron variant dominated. After May 2021, two distinct variant groups (Delta and Omicron) were observed, equally distributed among the five Santa Catarina mesoregions. Moreover, from November 2021 to February 2022, similar variant profiles between HCW and the general population were observed, and a quicker shift from Delta to Omicron in HCW than in the general population. This demonstrates the importance of HCW as a sentinel group for monitoring disease trends in the general population.

Socioeconomic inequality in hospital case fatality rate and care among children and adolescents hospitalized for COVID-19 in Brazil.

OBJECTIVE: To analyze the association of hospital case fatality rate and care received by children and adolescents hospitalized for COVID-19 with the gross domestic product (GDP) per capita of Brazilian municipalities and regions of residence. METHODS: Data were collected from the Influenza Epidemiological Surveillance Information System and the Brazilian Institute of Geography and Statistics. The dichotomous outcomes analyzed were hospital case fatality rate of COVID-19, biological samples collected for COVID-19 diagnosis, X-rays, computed tomography (CT) scans, use of ventilatory support, and intensive care unit hospitalization. The covariates were municipal GDP per capita and the Brazilian region of residence. Poisson regression was used for the outcomes recorded in 2020 and 2021 in Brazil, covering the two COVID-19 waves in the country, adjusted for age and gender. RESULTS: The hospital case fatality rate was 7.6%. In municipalities with lower GDP per capita deciles, the case fatality rate was almost four times higher among children and twice as high in adolescents compared to cities with higher deciles. Additionally, residents of municipalities with lower GDP per capita had fewer biological samples collected for diagnosis, X-ray examinations, and CT scans. We found regional disparities associated with case fatality rate, with worse indicators in the North and Northeast regions. The findings remained consistent over the two COVID-19 waves. CONCLUSION: Municipalities with lower GDP per capita, as well as the North and Northeast regions, had worse indicators of hospital case fatality rate and care.

Influence of alcohol and tobacco consumption on maternal and perinatal outcomes of puerperal women attended at the Brazilian National Health System / Influência do consumo de álcool e tabaco em desfechos maternos e perinatais de puérperas atendidas no Sistema Único de Saúde

Abstract Objectives: to evaluate the association between alcohol and tobacco consumption during pregnancy with maternal and child health conditions. Methods: cross-sectional study with a probabilistic sample of pregnant women living in Santa Catarina who conducted prenatal care and childbirth in the public national health service in 2019. A face-to-face survey questionnaire was applied to 3,580 pregnant women including maternal health issues during pregnancy and perinatal health of the newborn. Crude logistic regression analyzes were performed and adjusted for socio-demographic and maternal health conditions. Results: the prevalence of alcohol and tobacco consumption during pregnancy was 7.2% and 9.3%, respectively. Alcohol consumption during pregnancy increased the chance of maternal anemia by 45% (CI95%=1.09-1.91), increased the chance of gestational diabetes by 73% (CI95%=1.14-2.63) and reduced the chance of hypertension (OR=0.59; CI95%=0.37-0.94). Tobacco consumption doubled the chance of low birth weight (OR=2.16; CI95%=1.33-3.51). Conclusion: the consumption of alcoholic beverages during pregnancy increased the chance of maternal health complications, such as anemia and gestational diabetes, while tobacco increased the chance of low birth weight.

Resumo Objetivos: avaliar a associação entre o consumo de álcool e de tabaco durante a gravidez com condições de saúde maternas e da criança. Métodos: estudo transversal com amostra probabilística de gestantes residentes em Santa Catarina que realizaram o pré-natal e o parto na rede pública do estado em 2019. Foi aplicado questionário face-a-face com 3.580 gestantes incluindo questões de saúde maternas durante a gestação e saúde perinatal do recém-nascido. Foram realizadas análises de regressão logística brutas e ajustadas para condições sócio-demográficas e de saúde maternas. Resultados: as prevalências de consumo de bebidas alcoólicas e de tabaco durante a gestação foram de 7,2% e 9,3%, respectivamente. O consumo de álcool durante a gestação aumentou em 45% a chance de anemia materna (IC95%=1,09-1,91) e em 73% a de diabetes gestacional (IC95%=1,14-2,63) e reduziu a chance de hipertensão (OR=0,59; IC95%=0,37-0,94). O consumo de tabaco dobrou a chance de baixo peso gestacional ao nascer (OR=2,16; IC95%=1,33-3,51). Conclusão: o consumo de bebidas alcoólicas durante a gestação aumentou a chance de intercorrências de saúde maternas, como anemia e diabetes gestacional, enquanto o tabaco aumentou a chance de baixo peso ao nascer.

Socioeconomic inequality in hospital case fatality rate and care among children and adolescents hospitalized for COVID-19 in Brazil / Desigualdade socioeconômica na letalidade e no cuidado hospitalar de crianças e adolescentes internados por COVID-19 no Brasil

ABSTRACT Objective: To analyze the association of hospital case fatality rate and care received by children and adolescents hospitalized for COVID-19 with the gross domestic product (GDP) per capita of Brazilian municipalities and regions of residence. Methods: Data were collected from the Influenza Epidemiological Surveillance Information System and the Brazilian Institute of Geography and Statistics. The dichotomous outcomes analyzed were hospital case fatality rate of COVID-19, biological samples collected for COVID-19 diagnosis, X-rays, computed tomography (CT) scans, use of ventilatory support, and intensive care unit hospitalization. The covariates were municipal GDP per capita and the Brazilian region of residence. Poisson regression was used for the outcomes recorded in 2020 and 2021 in Brazil, covering the two COVID-19 waves in the country, adjusted for age and gender. Results: The hospital case fatality rate was 7.6%. In municipalities with lower GDP per capita deciles, the case fatality rate was almost four times higher among children and twice as high in adolescents compared to cities with higher deciles. Additionally, residents of municipalities with lower GDP per capita had fewer biological samples collected for diagnosis, X-ray examinations, and CT scans. We found regional disparities associated with case fatality rate, with worse indicators in the North and Northeast regions. The findings remained consistent over the two COVID-19 waves. Conclusion: Municipalities with lower GDP per capita, as well as the North and Northeast regions, had worse indicators of hospital case fatality rate and care.

RESUMO Objetivo: Analisar a associação entre a letalidade e o cuidado hospitalar recebido por crianças e adolescentes internados por COVID-19 e o produto interno bruto (PIB) per capita dos municípios brasileiros e a região de residência. Métodos: Os dados foram extraídos do Sistema de Informação de Vigilância Epidemiológica da Gripe e do Instituto Brasileiro de Geografia e Estatística. Analisaram-se como desfechos dicotômicos a letalidade hospitalar por COVID-19, a coleta de amostra biológica para diagnóstico de COVID-19, a realização de exames raio X e tomografia, o uso de suporte ventilatório e a internação em unidade de terapia intensiva. As covariáveis foram o PIB municipal per capita e a região brasileira de residência. Foi realizada regressão de Poisson para os desfechos registrados em 2020 e 2021 no Brasil e segundo o período compreendido em duas ondas de COVID-19 no país, ajustando-a por idade e sexo. Resultados: A letalidade hospitalar foi de 7,6%. Nos municípios dos menores decis de PIB per capita a letalidade foi quase quatro vezes maior entre crianças e duas vezes mais elevada entre adolescentes quando comparada àquela dos maiores decis. Adicionalmente, os residentes de municípios com menor PIB per capita realizaram menos coleta de amostra biológica para diagnóstico, exames de raio X e tomografias. Foram encontradas disparidades regionais associadas à letalidade, com piores indicadores nas regiões Norte e Nordeste. Os achados mantiveram-se consistentes durante as duas ondas de COVID-19. Conclusão: Em municípios com menor PIB per capita e das regiões Norte e Nordeste houve piores indicadores de letalidade e cuidado hospitalar.

Area-level inequalities in Covid-19 outcomes in Brazil in 2020 and 2021: An analysis of 1,894,165 severe Covid-19 cases.

The study aims to analyze inequalities in Covid-19 outcomes in Brazil in 2020/2021 according to the per capita Gross Domestic Product (pcGDP) of municipalities. All cases of Severe Acute Respiratory Syndrome (SARS) who were hospitalized or died, regardless of hospitalization, registered in Brazil in 2020 and 2021 were analyzed (n = 2,902,742), including those with a confirmed diagnosis of Covid-19 (n = 1,894,165). We calculated lethality due to Covid-19, the performance of diagnostic tests among patients with SARS, and the hospital care received by those with Covid-19 according to the pcGDP of the patients' municipalities of residence. Data were analyzed for each epidemiological week and the risk of each outcome was estimated using Poisson regression. Municipalities in the lowest pcGDP decile had (i) 30% (95%CI 28%-32%) higher lethality from Covid-19, (ii) three times higher proportion of patients with SARS without the collection of biological material for the diagnosis of Covid-19, (iii) 16% (95%CI 15%-16%) higher proportion of SARS patients testing in a period longer than two days from the onset of symptoms, (iv) 140% (95%CI 134%-145%) higher absence of CT scan use. There is deep socioeconomic inequality among Brazilian municipalities regarding the occurrence of Covid-19 negative outcomes.

[Prevalence rates and inequalities in access to medicines by users of the Brazilian Unified National Health System in 2013 and 2019]. / Prevalências e desigualdades no acesso aos medicamentos por usuários do Sistema Único de Saúde no Brasil em 2013 e 2019.

The study aimed to analyze and compare the prevalence of access to medicines and associated factors among users of the Brazilian Unified National Health System (SUS). The authors analyzed data from the 2013 and 2019 editions of the Brazilian National Health Survey, a nationwide health study, representative of the Brazilian population. The outcomes were: (1) obtaining from the SUS all the medicines prescribed during care received in the SUS itself in the two weeks prior to the interview (2) and obtaining all the medicines, regardless of the source. Demographic and socioeconomic characteristics were included as independent variables. In 2019, 29.7% of the interviewees obtained all the prescribed medicines from the SUS, 81.8% obtained all the medicines in general (considering all sources), and 56.4% paid some amount for the medicines. The proportion who did obtain any medicine from the SUS and that made some out-of-pocket payment increased from 2013 to 2019. The likelihood of obtaining all the medicines in the SUS was higher among the poorest, and that of obtaining the medicines regardless of source was higher among the wealthiest. Approximately two out of three persons that were unable to access all the medicines reported difficulties obtaining them in services funded by the public sector. There was an increase in out-of-pocket expenditure on medicines in Brazil and a reduction in access through the SUS, among users of the system.

O objetivo do estudo foi analisar e comparar a prevalência, a forma de obtenção e os fatores associados ao acesso a medicamentos entre usuários do Sistema Único de Saúde (SUS) no Brasil. Foram analisados os dados das edições 2013 e 2019 da Pesquisa Nacional de Saúde, estudo de abrangência nacional e representativo da população brasileira. Os desfechos foram: (1) a obtenção total, por meio do SUS, dos medicamentos prescritos em atendimentos em saúde realizados no próprio SUS nas duas semanas anteriores à entrevista, e (2) a obtenção total dos medicamentos independentemente da fonte. Características demográficas e socioeconômicas foram incluídas como variáveis independentes. Em 2019, observou-se que 29,7% dos entrevistados obtiveram no SUS todos os medicamentos prescritos, que 81,8% tiveram acesso total aos medicamentos quando consideradas todas as fontes de obtenção e que 56,4% pagaram algum valor pelos medicamentos. A proporção de pessoas que não obtiveram nenhum medicamento no SUS e que efetuaram algum desembolso direto aumentou entre 2013 e 2019. A probabilidade de obter todos os medicamentos no SUS foi maior entre os mais pobres, e de consegui-los, independentemente da fonte, foi maior entre os mais ricos. Dentre as pessoas que não conseguiram acesso a todos os medicamentos, aproximadamente duas em cada três indicaram como principal motivo dificuldades de obtenção encontradas em serviços financiados pelo setor público. Verificou-se ampliação do desembolso direto para compra de medicamentos no Brasil e redução de acesso pelo SUS entre usuários do sistema.

El objetivo de este estudio fue analizar y comparar la prevalencia, la forma de obtención y los factores asociados al acceso a los medicamentos entre los usuarios del Sistema Único de Salud (SUS) en Brasil. Se analizaron los datos de las ediciones 2013 y 2019 de la Encuesta Nacional de Salud, un estudio de cobertura nacional y representativo de la población brasileña. Los resultados fueron: (1) la obtención total, a través del SUS, de los medicamentos prescritos en los servicios de salud realizados en el propio SUS en las dos semanas anteriores a la entrevista, y (2) la obtención total de los medicamentos independientemente de la fuente. Las características demográficas y socioeconómicas se incluyeron como variables independientes. En 2019 se observó que el 29,7% de los entrevistados obtuvo todos los medicamentos prescritos en el SUS, que el 81,8% tuvo acceso total a los medicamentos al considerar todas las fuentes de obtención y que el 56,4% pagó por los medicamentos. La proporción de personas que no obtuvieron ningún medicamento en el SUS y que realizaron algún gasto directo aumentó entre 2013 y 2019. Entre los pobres, la probabilidad de obtener todos los medicamentos del SUS fue mayor, y entre los más ricos también fue mayor esta obtención independientemente de la fuente. Entre las personas que no pudieron acceder a todos los medicamentos, aproximadamente dos de cada tres indicaron como razón principal las dificultades que se encuentran en los servicios financiados con fondos públicos. Hubo un aumento del gasto directo para la compra de medicamentos en Brasil y una reducción del acceso a través del SUS entre los usuarios del sistema.

Air Pollution, Socioeconomic Status, and Age-Specific Mortality Risk in the United States.

Importance: Prior studies on the association between fine particulate matter with diameters 2.5 µm or smaller (PM2.5) and probability of death have not applied multilevel analysis disaggregating data for US census tract, states, and counties, nor tested its interaction by socioeconomic status (SES). Such an approach could provide a more refined identification and targeting of populations exposed to increased risk from PM2.5. Objective: To assess the association between PM2.5 and age-specific mortality risk (ASMR) using disaggregated data at the census tract level and evaluate such association according to census tract SES. Design, Setting, and Participants: This nationwide cross-sectional study used a linkage of 3 different data sets. ASMR for the period of 2010 to 2015 was obtained from the National Center for Health Statistic, SES data covering a period from 2006 to 2016 came from the American Community Survey, and mean PM2.5 exposure levels from 2010 to 2015 were derived from well-validated atmospheric chemistry and machine learning models. Data were analyzed in April 2021. Exposures: The main exploratory variable was mean census tract-level long-term exposure to PM2.5 from 2010 to 2015. Main Outcomes and Measures: The primary outcome was census tract-level ASMR. Multilevel models were used to quantify the geographic variation in ASMR at levels of census tract, county, and state. Additional analysis explored the interaction of SES in the association of ASMR with PM2.5 exposure. Results: Data from 67 148 census tracts nested in 3087 counties and 50 states were analyzed. The association between exposure to PM2.5 and ASMR varied substantially across census tracts. The magnitude of such association also varied across age groups, being higher among adults and older adults. Census tracts accounted for most of the total geographic variation in mortality risk (range, 77.0%-94.2%). ASMR was higher in deciles with greater PM2.5 concentration. For example, ASMR for age 75 to 84 years was 54.6 per 1000 population higher in the decile with the second-highest PM2.5 concentration than in the decile with the lowest PM2.5 concentration. The ASMR, PM2.5 concentrations, and magnitude of the association between both were higher in the census tracts with the lowest SES. Conclusions and Relevance: This cross-sectional study found that census tracts with lower SES presented higher PM2.5 concentrations. ASMR and air pollution varied substantially across census tracts. There was an association between air pollution and ASMR across all age groups in the United States. These findings suggest that equitable public policies aimed at improving air quality are needed and important to increase life expectancy.

Dental care and associated factors during prenatal care: a crosssectional study with puerperal women in hospitals of the Unified Health System, Santa Catarina, Brazil, 2019 / Consulta odontológica y factores asociados durante la atención prenatal: estudio transversal con mujeres puerperales en hospitales del Sistema Único de Salud, Santa Catarina, Brasil, 2019 / Prevalência de consulta odontológica e fatores associados a sua realização durante o pré-natal: estudo transversal com puérperas em hospitais do Sistema Único de Saúde, Santa Catarina, 2019

Objective: to analyze the prevalence and associated factors of dental consultation during prenatal care. Methods: cross-sectional study based on interviews with puerperal women in 31 hospitals in the Unified Health System (SUS) in Santa Catarina, 2019.Sociodemographic,economic and prenatal related data were collected. Multivariate analyzes were performed using logistic regression to calculate the odds ratios (OR, odds ratio). Results: 3,580 puerperal women were included and 41.4% [95% confidence interval (95%CI) 39.7;43.0] underwent dental consultations during prenatal care. Higher chance of consultation was observed with higher education (OR=1.35 ­ 95%CI 1.06;1.71) and greater number of medical/nursing consultations (OR=1.97 ­ 95%CI 1.47;2.65) and the chance of not having paid work decreased (OR=0.82 ­ 95%CI 0.70;0.96) and of not participating in an educational activity at SUS (OR=0.63 ­ 95%CI 0.52;0.77). Conclusion: Factors related to education, employment, prenatal consultations and educational activities increased the chance of dental consultations during pregnancy in Santa Catarina.
