ABSTRACT

Resumo Objetivou-se analisar a tendência dos indicadores do Programa Nacional de Imunizações (PNI) em menores de um ano e classificar os municípios quanto ao risco de transmissão de doenças imunopreveníveis (RTDIp) no Maranhão de 2010 a 2021. Estudo ecológico de série temporal, baseado em dados secundários de cobertura vacinal (CV), homogeneidade de cobertura vacinal (HCV), proporção de abandono (PA) e RTDIp, com abrangência estadual, para vacinas do calendário nacional infantil. Regressão de Prais-Winstein estimou tendência (α = 5%) e variação percentual anual (VPA) dos indicadores. Houve CV flutuantes e discrepantes entre as vacinas, com tendência decrescente (p < 0,01), exceto contra hepatite B (p = 0,709) e rotavírus (p = 0,143). As quedas mais acentuadas foram para as vacinas contra febre amarela e BCG. Todas as taxas de HCV estavam abaixo do esperado, com a diminuição a partir de 2014 e VPA de 5,75% a 14,02%. Houve tendência crescente da PA para pentavalente e poliomielite. No período de 2015 e 2021 houve incremento de 52,54% na proporção dos municípios maranhenses com RTDIp muito alto (p = 0,025) e alto (p = 0,028). Ao longo de 12 anos, houve piora dos indicadores do PNI em menores de um ano, reafirmando a suscetibilidade para o surgimento de doenças imunopreveníveis.


Abstract We aimed to analyze the trend of indicators of the National Immunization Program (acronym in Portuguese. PNI) in children under one-year-old and classify municipalities regarding the risk of transmission of vaccine-preventable diseases (RTVPD) in Maranhão from 2010 to 2021. This ecological time series study was based on secondary data on vaccination coverage (VC). vaccination coverage homogeneity (VCH). proportion of abandonment (PA). and RTVPD. with state coverage for vaccines in the national children's calendar. Prais-Winsten regression estimated trends (α=5%) and the indicators' annual percentage change (APC). We identified fluctuating and discrepant VC between vaccines. with a decreasing trend (p < 0.01). except those against Hepatitis B (p = 0.709) and oral human rotavirus (p = 0.143). The sharpest falls were for Yellow Fever (APC = 12.24%) and BCG (APC = 12.25%) vaccines. All VCH rates were lower than expected. with a drop from 2014 and APC between 5.75% (Pneumococcal 10; p = 0.033) and 14.02% (Poliomyelitis; p < 0.01). We observed an increasing trend in PA for Pentavalent (APC = 4.91%; p < 0.01) and Poliomyelitis (APC = 3.55%; p < 0.01). We identified an increase of 52.54% in the proportion of municipalities in Maranhão from 2015 to 2021. with extremely high (p = 0.025) and high (p = 0.028) RTVPD. The PNI indicators deteriorated. reaffirming the susceptibility to the emergence of vaccine-preventable diseases.

ABSTRACT

ABSTRACT OBJECTIVE To estimate the 2020 all-cause and COVID-19 excess mortality according to sex, age, race/color, and state, and to compare mortality rates by selected causes with that of the five previous years in Brazil. METHODS Data from the Mortality Information System were used. Expected deaths for 2020 were estimated from 2015 to 2019 data using a negative binomial log-linear model. RESULTS Excess deaths in Brazil in 2020 amounted to 13.7%, and the ratio of excess deaths to COVID-19 deaths was 0.90. Reductions in deaths from cardiovascular diseases (CVD), respiratory diseases, and external causes, and an increase in ill-defined causes were all noted. Excess deaths were also found to be heterogeneous, being higher in the Northern, Center-Western, and Northeastern states. In some states, the number of COVID-19 deaths was lower than that of excess deaths, whereas the opposite occurred in others. Moreover, excess deaths were higher in men aged 20 to 59, and in black, yellow, or indigenous individuals. Meanwhile, excess mortality was lower in women, in individuals aged 80 years or older, and in whites. Additionally, deaths among those aged 0 to 19 were 7.2% lower than expected, with reduction in mortality from respiratory diseases and external causes. There was also a drop in mortality due to external causes in men and in those aged 20 to 39 years. Moreover, reductions in deaths from CVD and neoplasms were noted in some states and groups. CONCLUSION There is evidence of underreporting of COVID-19 deaths and of the possible impact of restrictive measures in the reduction of deaths from external causes and respiratory diseases. The impacts of COVID-19 on mortality were heterogeneous among the states and groups, revealing that regional, demographic, socioeconomic, and racial differences expose individuals in distinct ways to the risk of death from both COVID-19 and other causes.

ABSTRACT

ABSTRACT OBJECTIVE To identify the Brazilian cohorts that started either in the prenatal period or at birth, to describe their characteristics and the explored variables, and to map the cohorts with potential for studies on early determinants on health and the risk of falling ill on later stages of the life cycle. METHODS A scoping review was carried out. The articles were searched in the electronic databases PubMed and Virtual Health Library (VHL). The descriptors used were [((("Child" OR "Child, Preschool" OR "Infant" OR "Infant, Newborn") AND (Cohort Studies" OR "Longitudinal Studies")) AND "Brazil")]. The inclusion criteria were Brazilian cohorts that started the baseline in the prenatal period or at birth and with at least two follow-ups with the participants. In order to meet the concept of LCE, we excluded those cohorts whose follow-ups were restricted to the first year of life, as well as those that did not address biological, behavioral and psychosocial aspects, and cohorts with data collection of a single stage of the life cycle. RESULTS The search step identified 5,010 articles. Eighteen cohorts were selected for descriptive synthesis. The median number of baseline participants was 2,000 individuals and the median age at the last follow-up was 9 years. Sample loss at the last follow-up ranged from 9.2 to 87.5%. Most cohorts monitored two phases of the life cycle (the perinatal period and childhood). The Southern region had the highest number of cohorts. The main variables collected were sociodemographic and environmental aspects of the family, morbidity aspects, nutritional practices and lifestyle. CONCLUSIONS We recommend the continuity of these cohorts, the approach to different social contexts and the performance of follow-ups with participants in different phases of the life cycle for the strengthening and expansion of life course epidemiology analyses in Brazil.


RESUMO OBJETIVO Identificar as coortes brasileiras iniciadas no período pré-natal ou no nascimento, descrever suas características e as variáveis exploradas, além de mapear as coortes com potencial para se estudar os determinantes precoces de saúde e doença e o risco de adoecer em etapas posteriores do ciclo vital. MÉTODOS Realizou-se uma revisão de escopo. A busca dos artigos foi realizada nas bases de dados PubMed e Biblioteca Virtual em Saúde em 16 de junho de 2018. Os descritores utilizados foram [((("Child" OR "Child, Preschool" OR "Infant" OR "Infant, Newborn") AND ("Cohort Studies" OR "Longitudinal Studies")) AND "Brazil")]. Os critérios de inclusão foram coortes brasileiras que iniciaram a linha de base no período pré-natal ou no nascimento e com pelo menos dois acompanhamentos com os participantes. Foram excluídas as coortes cujos acompanhamentos foram restritos ao primeiro ano de vida, as que não abordaram aspectos biológicos, comportamentais e psicossociais e também aquelas com coleta de informações em um único estágio do ciclo vital. RESULTADOS A etapa de busca identificou 5.010 artigos. Foram selecionadas 18 coortes para a síntese descritiva. A mediana do número de participantes na linha de base foi 2.000 indivíduos e a mediana de idade no último acompanhamento foi 9 anos. A perda amostral no último acompanhamento variou de 9,2 a 87,5%. A maioria das coortes realizou acompanhamentos em duas fases do ciclo vital (período perinatal e infância). A região Sul contemplou o maior número de coortes. As principais variáveis coletadas foram sociodemográficas e ambientais da família, aspectos de morbidade, práticas alimentares e estilo de vida dos participantes. CONCLUSÕES Recomenda-se a continuidade dessas coortes, a abordagem de diferentes contextos sociais e a realização de acompanhamentos com os participantes em diferentes fases do ciclo vital para o fortalecimento e ampliação das análises de epidemiologia do ciclo vital no Brasil.

ABSTRACT

Objetivo: calcular taxas de mortalidade no primeiro dia de vida entre 2010 e 2015 em oito Unidades da Federação brasileira com melhor qualidade de informação, avaliar fatores associados e classificar os óbitos segundo causa básica e evitabilidade. Métodos: estudo descritivo; as taxas foram comparadas conforme características maternas e da criança; a análise de evitabilidade usou a 'Lista brasileira de causas de mortes evitáveis'. Resultados: 21,6% (n=20.791) dos óbitos infantis ocorreram no primeiro dia de vida; a taxa de mortalidade reduziu-se de 2,7 para 2,3 óbitos/1.000 nascidos vivos; observaram-se maiores taxas em NV com baixo peso, nascidos pré-termo e filhos de mães sem escolaridade; as principais causas dos óbitos foram síndrome da angústia respiratória (8,9%) e imaturidade extrema (5,2%); 66,3% das causas de óbito foram consideradas evitáveis. Conclusão: dois terços dos óbitos no primeiro dia de vida poderiam ser evitados por atenção adequada à mulher na gestação e no parto, e ao NV.


Objetivo: calcular la mortalidad en el primer día de vida entre 2010 y 2015 en ocho Unidades de la Federación brasileña con mejor calidad de información, analizar factores asociados y clasificar las causas básicas y la evitabilidad de los óbitos. Métodos: estudio descriptivo; las tasas de mortalidad fueron comparadas según las características maternas y del recién nacido (RN); el análisis de evitabilidad utilizó la 'Lista brasileña de causas de muertes evitables'. Resultados: un 21,6% (n=20.791) de los óbitos infantiles ocurrió en el primer día de vida; la tasa de mortalidad se redujo de 2,7 a 2,3 óbitos/1.000 nacidos vivos (NV); las tasas fueron mayores en NV de bajo peso, prematuros e hijos de madres sin escolaridad; las principales causas de óbito fueron síndrome de angustia respiratoria (8,9%) e inmadurez extrema (5,2%); un 66,3% de las causas de óbito fueron consideradas evitables. Conclusión: 2/3 de los óbitos en el primer día de vida podrían haber sido evitados con una atención adecuada a la mujer embarazada, al parto y al NV.


Objective: to calculate mortality rates on the first day of life from 2010 to 2015 in eight Brazilian Federative Units providing better quality information, to assess associated factors and to classify deaths by underlying causes and avoidability. Methods: this was a descriptive study; mortality rates were compared according to maternal and child characteristics; avoidability analysis used the 'Brazilian list of avoidable causes of death'. Results: 21.6% (n=20,791) of all infant deaths occurred on the first day of life; the mortality rate reduced from 2.7 to 2.3 deaths/1,000 live births; rates were higher in live births with low birthweight and preterm births, and among babies born to mothers with no schooling; main causes of death were respiratory distress syndrome (8.9%) and extreme immaturity (5.2%); 66.3% of causes of death were avoidable. Conclusion: 2/3 of deaths on the first day of life could have been avoided with adequate care for women during pregnancy and delivery and adequate care for live births.

ABSTRACT

Neste estudo, foram estimados percentuais de incompletude vacinal e fatores associados ao esquema vacinal para novas vacinas (EVNV) e esquema vacinal para antigas vacinas (EVAV) em crianças de 13 a 35 meses de idade de uma coorte de nascimento em São Luís, Maranhão, Brasil. A amostra foi probabilística, com 3.076 crianças nascidas em 2010. Informações sobre vacinação foram obtidas da Caderneta de Saúde da Criança. As vacinas consideradas para o EVNV foram meningocócica C e pneumocócica 10 valente, e para EVAV, vacinas BCG, hepatite B, rotavírus humano, poliomielite, tetravalente (vacina difteria, tétano, coqueluche e Haemophilus influenzae b), febre amarela, tríplice viral (vacina sarampo, caxumba, rubéola). Empregou-se modelagem hierarquizada e regressão de Poisson com variância robusta. Estimaram-se razões de prevalência (RP) e intervalos de 95% de confiança (IC95%). Incompletude vacinal foi maior para EVNV (51,1%) em relação ao EVAV (33,2%). Crianças com 25 a 35 meses de idade (RP = 1,27; IC95%: 1,14-1,41) e pertencer às classes D/E (RP = 1,20; IC95%: 1,06-1,35) se associaram somente ao EVNV; enquanto baixa escolaridade materna (RP = 1,58; IC95%: 1,21-2,06), indisponibilidade de atendimento ambulatorial e/ou hospitalar para a criança (RP = 1,20; IC95%: 1,04-1,38) e de vacina nos serviços de saúde (RP = 1,28; IC95%: 1,12-1,46), apenas ao EVAV. Faz-se importante considerar, nas estratégias de vacinação, a vulnerabilidade de crianças com mais idade e pertencentes às classes D e E, especialmente quando novas vacinas são introduzidas, e ainda de filhos de mães que possuem baixa escolaridade. Assim como, quando há menor disponibilidade de serviços de saúde para a criança e de vacina.


En este estudio se estimaron porcentajes de vacunación no completada y los factores asociados al esquema de vacunas para nuevas vacunas (EVNV) y al de antiguas vacunas (EVAV), en niños de 13 a 35 meses de edad de una cohorte de nacimiento en São Luís, Maranhão, Brasil. La muestra fue probabilística, con 3.076 niños nacidos en 2010. La información sobre la vacunación se obtuvo de la cartilla de salud del niño. Las vacunas consideradas para el EVNV fueron la meningocócica C y neumocócica 10 valente, y para EVAV, vacunas BCG, hepatitis B, rotavirus humano, poliomielitis, tetravalente (vacuna difteria, tétanos, tosferina y Haemophilus influenzae b), fiebre amarilla, triple viral (vacuna contra el sarampión, paperas, rubeola). Se empleó un modelo jerarquizado y la regresión de Poisson con variancia robusta. Se estimaron razones de prevalencia (RP) e intervalos de 95% de confianza (IC95%). La vacunación no completada fue mayor para EVNV (51,1%), en relación con el EVAV (33,2%). Ser niños de 25 a 35 meses de edad (RP = 1,27; IC95%: 1,14-1,41) y pertenecer a las clases D/E (RP = 1,20; IC95%: 1,06-1,35) se asociaron solamente al EVNV; mientras que la baja escolaridad materna (RP = 1,58; IC95%: 1,21-2,06), indisponibilidad de atención ambulatoria y/o hospitalaria para el niño (RP = 1,20; IC95%: 1,04-1,38) y de la vacuna en los servicios de salud (RP = 1,28; IC95%: 1,12-1,46), solamente al EVAV. Es importante considerar, en las estrategias de vacunación, la vulnerabilidad de los niños con más edad y pertenecientes a las clases D y E, especialmente cuando se introducen las nuevas vacunas, incluyendo también a los hijos de madres con baja escolaridad. También es problemática la existencia de una menor disponibilidad de servicios de salud para el niño y de la vacuna.


This study estimated the percentages of incomplete immunization with new vaccines and old vaccines and associated factors in children 13 to 35 months of age belonging to a birth cohort in São Luís, the capital of Maranhão State, Brazil. The sample was probabilistic, with 3,076 children born in 2010. Information on vaccination was obtained from the Child's Health Card. The new vaccines, namely those introduced in 2010, were meningococcal C and 10-valent pneumococcal, and the old vaccines, or those already on the childhood immunization schedule, were BCG, hepatitis B, human rotavirus, polio, tetravalent (diphtheria, tetanus, pertussis, Haemophilus influenzae b), yellow fever, and triple viral (measles, mumps, rubella). The study used hierarchical modeling and Poisson regression with robust variance. Prevalence ratios (PR) and 95% confidence intervals (95%CI) were calculated. Incomplete immunization was higher with new vaccines (51.1%) than with old vaccines (33.2%). Children 25 to 35 months of age (PR = 1.27; 95%CI: 1.14-1.41) and those in economic classes D/E (PR = 1.20; 95%CI: 1.06-1.35) were only significantly associated with new vaccines; low maternal schooling (PR = 1.58; 95%CI: 1.21-2.06), unavailability of outpatient and/or hospital care for the child (PR = 1.20; 95%CI: 1.04-1.38), and unavailability of the vaccine in health services (PR: 1.28; 95%CI: 1.12-1.46) were only associated with old vaccines. Immunization strategies should consider the vulnerability of older preschool-age children and those belonging to classes D and E, especially when new vaccines are introduced, as well as children of mothers with low schooling. Strategies should also address problems with the availability of health services and vaccines.

ABSTRACT

ABSTRACT OBJECTIVE The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. METHODS In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). RESULTS In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013. CONCLUSIONS The characteristics of the structure of primary health units and the work process of the primary care teams impact the number of hospitalizations for primary care sensitive conditions in Brazilian municipalities.


RESUMO OBJETIVO Investigar se características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica estão associadas ao número de internações por condições sensíveis à atenção primária. MÉTODOS Neste estudo ecológico, foram analisados dados de municípios brasileiros relativos a características sociodemográficas, de cobertura de programas assistenciais, de estrutura das unidades básicas de saúde e processo de trabalho das equipes de atenção básica. Os dados foram obtidos do primeiro ciclo do Programa de Melhoria do Acesso e Qualidade da Atenção Básica, do Departamento de Informática do Sistema Único de Saúde, do Instituto Brasileiro de Geografia e Estatística e do Programa das Nações Unidas. Estimaram-se as associações por meio de coeficientes de regressão binomial negativa (β) e respectivos intervalos de confiança a 95%, com abordagem hierarquizada em três blocos (alpha = 5%). RESULTADOS Na análise ajustada, para o desfecho em 2013, no bloco distal, a cobertura do Programa Bolsa Família (β = -0,001) e de plano privado (β = -0,01) apresentaram associação negativa; e o índice de desenvolvimento humano (β = 1,13), a proporção de pessoa idosa (β = 0,05) e de menor de cinco anos (β = 0,05) e a cobertura da Estratégia de Agentes Comunitários de Saúde (β = 0,002) mostraram associação positiva com internações por condições sensíveis à atenção primária. No bloco intermediário, apresentaram associação negativa o horário mínimo (β = -0,14) e a disponibilidade de vacina (β = -0,16); e associação positiva, a disponibilidade de medicamentos (β = 0,16). No bloco proximal, apenas a variável apoio matricial (β = 0,10) mostrou associação positiva. Na análise ajustada do número de internações por condições sensíveis à atenção primária em 2014, as variáveis apresentaram o mesmo sentido de associação de 2013. CONCLUSÕES Características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica impactam no número de internações por condições sensíveis à atenção primária nos municípios brasileiros.
