[How to improve active mobility in São Paulo, Brazil? Survey with leaders of nongovernmental organizations and public and private sector managers]. / Como melhorar a mobilidade ativa em São Paulo, Brasil? Inquérito com lideranças de organizações não governamentais e com gestores públicos e privados.

This study aimed to describe a quantitative survey conducted with leaders to investigate effective and feasible actions that can be evaluated in computational models to inform policies to promote active mobility based in the city of São Paulo, Brazil. In 2022, an online survey was conducted during the Health Survey in São Paulo (Physical Activity and Environment study), which is monitored by representatives of nongovernmental organizations and public and private sector managers. A questionnaire was elaborated with three questions with 13 alternative answers about actions to promote walking and/or cycling. Leaders should select up to three alternatives based on their potential regarding: (1) effectiveness; (2) feasibility or ease of implementation; and (3) desire to verify tests in computational models to inform policies. The survey was answered by 18 leaders from 16 institutions, comprising 13 (72%) women and 12 (67%) representatives of the third sector, whose average age was 48 years and all had complete higher education. Reducing the speed of motor vehicles was the most cited option in all three questions. Other actions mentioned refer to controlling the traffic of vehicles in central areas, improving pedestrian safety, reducing the distances between homes and places of employment, conducting educational campaigns, and expanding and enhancing structures such as bicycle lanes and sidewalks. The results are relevant to support evidence-based decision-making in public management and to provide subsidies for the development of computational models with a view to promoting active mobility.

The burden of disease due to COVID-19 in Florianópolis, Santa Catarina, Brazil, over a one-year period. / A carga de doença por COVID-19 em Florianópolis, Santa Catarina, Brasil, no período de um ano.

COVID-19 has had a powerful impact on society with high rates of morbidity and mortality. The use of an epidemiological indicator that estimates the burden of a disease by aggregating early mortality and non-fatal cases in a single measure has the potential to assist in the planning of more appropriate actions at different levels of health care. The scope of this article is to estimate the burden of disease due to COVID-19 in Florianópolis/SC from April 2020 through March 2021. An ecological study was carried out with data from notification and deaths by COVID-19 in the period of 12 months. The burden indicator called Disability-Adjusted Life Years (DALY) was used, obtained by adding the Years of Life Lost (YLL) to the Years of healthy life lost due to disability (YLD). A total of 78,907 confirmed COVID-19 cases were included. Of these, 763 died during the period under study. Overall, 4,496.9 DALYs were estimated, namely a rate of 883.8 DALYs per 100,000 inhabitants. In males, there were 2,693.1 DALYs, a rate of 1,098.0 DALYs per 100,000 males. In women, there were 1,803.8 DALYs, a rate of 684.4 DALYs per100,000 women. The age group most affected in both sexes was 60 to 69 years. The burden of COVID-19 was high in the city studied. The highest rates were in females and in the 60-69 age group.

A COVID-19 gerou impacto na sociedade com elevados índices de morbidade e mortalidade. A utilização de indicador epidemiológico que estime a carga de doença, agregando em uma medida a mortalidade precoce e os casos não fatais, tem potencial de auxiliar no planejamento de ações adequadas em diferentes níveis de atenção à saúde. O objetivo deste artigo é estimar a carga de doença por COVID-19 em Florianópolis/SC de abril de 2020 a março de 2021. Foi realizado um estudo ecológico com dados de notificação e óbitos por COVID-19 no período de 12 meses. Utilizou-se o indicador de carga denominado Anos de Vida Perdidos Ajustados por Incapacidade (DALY), obtido pela soma dos Anos de Vida Perdidos (YLL) com os Anos Vividos com Incapacidade (YLD). Foram incluídos 78.907 casos de COVID-19 confirmados. Desses, 763 evoluíram a óbito no período estudado. No total, foram estimados 4.496,6 DALYs, taxa de 883,8 DALYs/100.000 habitantes. No sexo masculino, foram 2.693,1 DALYs, taxa de 1.098,0 DALYs/100.000 homens. Em mulheres, foram 1.803,8 DALYs, taxa de 684,4 DALYs/100.000 mulheres. A faixa etária mais acometida em ambos os sexos foi de 60 a 69 anos. Foi alta a carga de COVID-19 na cidade estudada. As maiores taxas foram encontradas no sexo feminino e na faixa-etária de 60-69 anos.

What is the impact of national public expenditure and its allocation on neonatal and child mortality? A machine learning analysis.

BACKGROUND: Understanding the impact of national public expenditure and its allocation on child mortality may help governments move towards target 3.2 proposed in the 2030 Agenda. The objective of this study was to estimate the impacts of governmental expenditures, total, on health, and on other sectors, on neonatal mortality and mortality of children aged between 28 days and five years. METHODS: This study has an ecological design with a population of 147 countries, with data between 2012 and 2019. Two steps were used: first, the Generalized Propensity Score of public spending was calculated; afterward, the Generalized Propensity Score was used to estimate the expenditures' association with mortality rates. The primary outcomes were neonatal mortality rates (NeoRt) and mortality rates in children between 28 days and 5 years (NeoU5Rt). RESULTS: The 1% variation in Int$ Purchasing Power Parity (Int$ PPP) per capita in total public expenditures, expenditure in health, and in other sectors were associated with a variation of -0.635 (95% CI -1.176, -0.095), -2.17 (95% CI -3.051, -1.289) -0.632 (95% CI -1.169, -0.095) in NeoRt, respectively The same variation in public expenditures in sectors other than health, was associates with a variation of -1.772 (95% CI -6.219, -1.459) on NeoU5Rt. The results regarding the impact of total and health public spending on NeoU5Rt were not consistent. CONCLUSION: Public investments impact mortality in children under 5 years of age. Likely, the allocation of expenditures between the health sector and the other social sectors will have different impacts on mortality between the NeoRt and the NeoU5Rt.

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.

Impact assessment of emergency care units on hospitalizations for respiratory system diseases in Brazil / Avaliação do impacto das unidades de pronto atendimento sobre as internações por doenças do aparelho respiratório no Brasil

Abstract Emergency Care Units (UPAs) are part of a national health policy implemented by the Brazilian Government. UPAs are fixed prehospital components of the Brazilian Unified Health System (SUS), whose purpose is to provide resolutive emergency care to patients suffering from acute clinical conditions, and to perform the first care in cases of surgical nature. According to the Ministry of Economy, 750 units are operational throughout the country since 2008, and 332 are under construction. Being a public policy in expansion, it is imperative to assess the impact of such units as part of SUS. However, we found few studies that assessed UPAs' impact, which have examined their specific impact on mortality rates. In our research, we aimed to evaluate the impact of UPAs on hospitalization rates for diseases of the respiratory system. To measure the impact, we used a strategy of Machine Learning through the Bayesian Additive Regression Trees (BART) algorithm. The results point to a decrease in the hospitalization rates by respiratory diseases due to Emergency Care Units. Therefore, these units generate a benefit for the Brazilian health system, being an important element for the care of patients with respiratory diseases.

Resumo As Unidades de Pronto Atendimento 24h (UPAs) compõem a Política de Atenção a Urgências e Emergências (PNAU) implementada pelo Governo Federal. São componentes pré-hospitalares fixos do SUS, cujo objetivo é o atendimento resolutivo de urgência a pacientes que sofrem quadros clínicos agudos, e o primeiro atendimento em casos cirúrgicos. Desde 2008, funcionam 750 unidades no Brasil, e há 332 em construção, conforme dados de 2020 do Ministério da Economia. Diante de uma política em expansão, é indispensável avaliar seus efeitos como parte do SUS. No entanto, foram encontrados poucos trabalhos avaliando o impacto das UPAs, e esses mediram os efeitos sobre taxas de mortalidade. Este trabalho objetiva mensurar o efeito das UPAs nas taxas de internação por doenças do aparelho respiratório. Para isso, utilizou-se uma estratégia de Machine Learning por meio do algoritmo Bayesian Additive Regression Trees (BART). Os resultados apontam uma diminuição nas taxas de internações por doenças do aparelho respiratório devido às UPAs. Assim, as evidências são de que essas unidades geram benefício para o sistema de saúde, sendo uma peça importante na linha de cuidado dos pacientes com doenças respiratórias.

GroundsWell: Community-engaged and data-informed systems transformation of Urban Green and Blue Space for population health - a new initiative.

Natural environments, such as parks, woodlands and lakes, have positive impacts on health and wellbeing. Urban Green and Blue Spaces (UGBS), and the activities that take place in them, can significantly influence the health outcomes of all communities, and reduce health inequalities. Improving access and quality of UGBS needs understanding of the range of systems (e.g. planning, transport, environment, community) in which UGBS are located. UGBS offers an ideal exemplar for testing systems innovations as it reflects place-based and whole society processes , with potential to reduce non-communicable disease (NCD) risk and associated social inequalities in health. UGBS can impact multiple behavioural and environmental aetiological pathways. However, the systems which desire, design, develop, and deliver UGBS are fragmented and siloed, with ineffective mechanisms for data generation, knowledge exchange and mobilisation. Further, UGBS need to be co-designed with and by those whose health could benefit most from them, so they are appropriate, accessible, valued and used well. This paper describes a major new prevention research programme and partnership, GroundsWell, which aims to transform UGBS-related systems by improving how we plan, design, evaluate and manage UGBS so that it benefits all communities, especially those who are in poorest health. We use a broad definition of health to include physical, mental, social wellbeing and quality of life. Our objectives are to transform systems so that UGBS are planned, developed, implemented, maintained and evaluated with our communities and data systems to enhance health and reduce inequalities. GroundsWell will use interdisciplinary, problem-solving approaches to accelerate and optimise community collaborations among citizens, users, implementers, policymakers and researchers to impact research, policy, practice and active citizenship. GroundsWell will be shaped and developed in three pioneer cities (Belfast, Edinburgh, Liverpool) and their regional contexts, with embedded translational mechanisms to ensure that outputs and impact have UK-wide and international application.

What the Physical Activity Community Can Do for Climate Action and Planetary Health?

We are experiencing a planetary tipping point with global warming, environmental degradation, and losses in biodiversity. The burdens of these changes fall disproportionately on poor and marginalized populations. Physical activity promotion strategies need to be aligned with climate action commitments, incorporating the Intergovernmental Panel on Climate Change scenarios in physical activity action plans. The promotion strategies must consider equity a core value and promote physical activity to the most vulnerable populations so that they are protected from the ill-health impacts of a changing climate.

[Identification and analysis of national physical activity guidelines in the Americas]. / Identificação e análise das diretrizes nacionais de atividade física nas Américas.

Given the potential of institutional approaches to health promotion, this study sought to identify the countries on the American continent which have national physical activity (PA) guidelines approved by their national health agencies. A scoping review was conducted in May 2019, with a search conducted in five electronic databases, national health agency websites and contacts with members of the Physical Activity Network of the Americas. In all, national PA guidelines were found in ten of the 36 countries surveyed (27.8%), published between 2011 and 2018, the majority being in South American countries (n = 6). All guidelines presented "approaches and strategies for primary health care," "PA recommendations for health," and the "involvement of different PA domains," however, few guidelines addressed "constructed environment and infrastructure" (n = 3), as well as "monitoring and surveillance actions" (n = 5). The conclusion can be drawn that, although few countries on the American continent have guidelines for PA and that the majority of those available address PA in a limited way, new national guidelines, based on the complexity of the determinants, monitoring and consequences of PA are needed to guide and foster policies to promote PA within the population.

Visto o potencial das abordagens institucionais à promoção da saúde, o presente estudo buscou identificar os países do continente americano que possuem diretrizes nacionais de atividade física (AF) chanceladas por órgãos nacionais de saúde. Em maio de 2019 realizou-se uma revisão de escopo, com buscas em cinco bases de dados eletrônicas, sítios eletrônicos dos órgãos nacionais de saúde e contato com integrantes da Rede de Atividade Física das Américas. Foram encontradas diretrizes nacionais de AF em dez dos 36 países pesquisados (27,8%), publicadas entre 2011 e 2018, com maioria nos países da América do Sul (n=6). Todas as diretrizes apresentaram "abordagens e estratégias para a atenção primária em saúde", "recomendações de AF para a saúde" e o "envolvimento de distintos domínios da AF", contudo, poucas diretrizes abordaram o "ambiente construído e infraestrutura" (n=3), assim como "ações de monitoramento e vigilância" (n=5). Pode-se concluir que, ao passo que poucos países do continente americano dispõem de diretrizes para a AF e, que boa parte das disponíveis aborda a AF de maneira limitada, novas diretrizes nacionais, fundamentadas na complexidade dos determinantes, monitoramento e consequências da AF são necessárias para a orientação e incentivo de políticas de promoção da AF no contexto populacional.

Physical Activity Promotion and the United Nations Sustainable Development Goals: Building Synergies to Maximize Impact.

BACKGROUND: Many of the known solutions to the physical inactivity pandemic operate across sectors relevant to the United Nations Sustainable Development Goals (SDGs). METHODS: The authors examined the contribution of physical activity promotion strategies toward achieving the SDGs through a conceptual linkage exercise, a scoping review, and an agent-based model. RESULTS: Possible benefits of physical activity promotion were identified for 15 of the 17 SDGs, with more robust evidence supporting benefits for SDGs 3 (good health and well-being), 9 (industry, innovation, and infrastructure), 11 (sustainable cities and communities), 13 (climate action), and 16 (peace, justice, and strong institutions). Current evidence supports prioritizing at-scale physical activity-promoting transport and urban design strategies and community-based programs. Expected physical activity gains are greater for low-and middle-income countries. In high-income countries with high car dependency, physical activity promotion strategies may help reduce air pollution and traffic-related deaths, but shifts toward more active forms of travel and recreation, and climate change mitigation, may require complementary policies that disincentivize driving. CONCLUSIONS: The authors call for a synergistic approach to physical activity promotion and SDG achievement, involving multiple sectors beyond health around their goals and values, using physical activity promotion as a lever for a healthier planet.

Effect of COVID-19 response policies on walking behavior in US cities.

The COVID-19 pandemic is causing mass disruption to our daily lives. We integrate mobility data from mobile devices and area-level data to study the walking patterns of 1.62 million anonymous users in 10 metropolitan areas in the United States. The data covers the period from mid-February 2020 (pre-lockdown) to late June 2020 (easing of lockdown restrictions). We detect when users were walking, distance walked and time of the walk, and classify each walk as recreational or utilitarian. Our results reveal dramatic declines in walking, particularly utilitarian walking, while recreational walking has recovered and even surpassed pre-pandemic levels. Our findings also demonstrate important social patterns, widening existing inequalities in walking behavior. COVID-19 response measures have a larger impact on walking behavior for those from low-income areas and high use of public transportation. Provision of equal opportunities to support walking is key to opening up our society and economy.

Advancing the global physical activity agenda: recommendations for future research by the 2020 WHO physical activity and sedentary behavior guidelines development group.

BACKGROUND: In July, 2019, the World Health Organization (WHO) commenced work to update the 2010 Global Recommendations on Physical Activity for Health and established a Guideline Development Group (GDG) comprising expert public health scientists and practitioners to inform the drafting of the 2020 Guidelines on Physical Activity and Sedentary Behavior. The overall task of the GDG was to review the scientific evidence and provide expert advice to the WHO on the amount of physical activity and sedentary behavior associated with optimal health in children and adolescents, adults, older adults (> 64 years), and also specifically in pregnant and postpartum women and people living with chronic conditions or disabilities. METHODS: The GDG reviewed the available evidence specific to each sub-population using systematic protocols and in doing so, identified a number of gaps in the existing literature. These proposed research gaps were discussed and verified by expert consensus among the entire GDG. RESULTS: Evidence gaps across population sub-groups included a lack of information on: 1) the precise shape of the dose-response curve between physical activity and/or sedentary behavior and several of the health outcomes studied; 2) the health benefits of light-intensity physical activity and of breaking up sedentary time with light-intensity activity; 3) differences in the health effects of different types and domains of physical activity (leisure-time; occupational; transportation; household; education) and of sedentary behavior (occupational; screen time; television viewing); and 4) the joint association between physical activity and sedentary time with health outcomes across the life course. In addition, we acknowledge the need to conduct more population-based studies in low- and middle-income countries and in people living with disabilities and/or chronic disease, and to identify how various sociodemographic factors (age, sex, race/ethnicity, socioeconomic status) modify the health effects of physical activity, in order to address global health disparities. CONCLUSIONS: Although the 2020 WHO Guidelines for Physical Activity and Sedentary Behavior were informed by the most up-to-date research on the health effects of physical activity and sedentary time, there is still substantial work to be done in advancing the global physical activity agenda.

A systematic review of empirical and simulation studies evaluating the health impact of transportation interventions.

Urban transportation is an important determinant of health and environmental outcomes, and therefore essential to achieving the United Nation's Sustainable Development Goals. To better understand the health impacts of transportation initiatives, we conducted a systematic review of longitudinal health evaluations involving: a) bus rapid transit (BRT); b) bicycle lanes; c) Open Streets programs; and d) aerial trams/cable cars. We also synthesized systems-based simulation studies of the health-related consequences of walking, bicycling, aerial tram, bus and BRT use. Two reviewers screened 3302 unique titles and abstracts identified through a systematic search of MEDLINE (Ovid), Scopus, TRID and LILACS databases. We included 39 studies: 29 longitudinal evaluations and 10 simulation studies. Five studies focused on low- and middle-income contexts. Of the 29 evaluation studies, 19 focused on single component bicycle lane interventions; the rest evaluated multi-component interventions involving: bicycle lanes (n = 5), aerial trams (n = 1), and combined bicycle lane/BRT systems (n = 4). Bicycle lanes and BRT systems appeared effective at increasing bicycle and BRT mode share, active transport duration, and number of trips using these modes. Of the 10 simulation studies, there were 9 agent-based models and one system dynamics model. Five studies focused on bus/BRT expansions and incentives, three on interventions for active travel, and the rest investigated combinations of public transport and active travel policies. Synergistic effects were observed when multiple policies were implemented, with several studies showing that sizable interventions are required to significantly shift travel mode choices. Our review indicates that bicycle lanes and BRT systems represent promising initiatives for promoting population health. There is also evidence to suggest that synergistic effects might be achieved through the combined implementation of multiple transportation policies. However, more rigorous evaluation and simulation studies focusing on low- and middle-income countries, aerial trams and Open Streets programs, and a more diverse set of health and health equity outcomes is required.

Risk factors for neonatal death in the capital city with the lowest infant mortality rate in Brazil / Fatores de risco para o óbito neonatal na capital com menor taxa de mortalidade infantil do Brasil

Abstract Objectives: To analyze the risk factors for neonatal death in Florianópolis, the Brazilian city capital with the lowest infant mortality rate. Method: Data were extracted from a historical cohort with 15,879 live births. A model was used that included socioeconomic, behavioral, and health service use risk factors, as well as the Apgar score and biological factors. Risk factors were analyzed by hierarchical logistic regression. Results: Based on the multivariate analysis, socioeconomic factors showed no association with death. Insufficient prenatal consultations showed an OR of 3.25 (95% CI: 1.70-6.48) for death. Low birth weight (OR 8.42; 95% CI: 3.45-21.93); prematurity (OR 5.40; 95% CI: 2.22-13.88); malformations (OR 4.42; 95% CI: 1.37-12.43); and low Apgar score at the first (OR 6.65; 95% CI: 3.36-12.94) and at the fifth (OR 19.78; 95% CI: 9.12-44.50) minutes, were associated with death. Conclusion: Differing from other studies, socioeconomic conditions were not associated with neonatal death. Insufficient prenatal consultations, low Apgar score, prematurity, low birth weight, and malformations showed an association, reinforcing the importance of prenatal access universalization and its integration with medium and high-complexity neonatal care services.

Resumo Objetivos: Analisar os fatores de risco para o óbito neonatal em Florianópolis, capital brasileira com a menor taxa de mortalidade infantil. Método: Os dados foram extraídos de coorte histórica, contando com 15.879 nascidos vivos. Utilizou-se modelo ordenando fatores de risco socioeconômicos, comportamentais e de utilização dos serviços de saúde, além do escore de Apgar e de fatores biológicos. Os fatores de risco foram analisados por regressão logística hierarquizada. Resultados: Com base na análise multivariada, os fatores socioeconômicos não mostraram associação com o óbito. Consultas pré-natais insuficientes apresentaram um OR 3,25 (IC95% 1,70-6,48) para óbito. Baixo peso ao nascer (OR 8,42; IC95% 3,45-21,93); prematuridade (OR 5,40; IC95% 2,22-13,88); malformações (OR 4,42; IC95% 1,37-12,43); baixo escore de Apgar no 1o (OR 6,65; IC95% 3,36-12,94) e no 5o (OR 19,78; IC95% 9,12-44,50) minutos associaram-se ao óbito. Conclusão: Diferente de outros estudos, as condições socioeconômicas não se associaram ao óbito neonatal. Pré-natal insuficiente, baixo escore de Apgar, prematuridade, baixo peso e malformações mostraram associação, reforçando a importância da universalização do acesso ao pré-natal e da integração deste com serviços de atenção ao recém-nascido, de média e alta complexidade.

Risk factors for neonatal death in the capital city with the lowest infant mortality rate in Brazil.

OBJECTIVES: To analyze the risk factors for neonatal death in Florianópolis, the Brazilian city capital with the lowest infant mortality rate. METHOD: Data were extracted from a historical cohort with 15,879 live births. A model was used that included socioeconomic, behavioral, and health service use risk factors, as well as the Apgar score and biological factors. Risk factors were analyzed by hierarchical logistic regression. RESULTS: Based on the multivariate analysis, socioeconomic factors showed no association with death. Insufficient prenatal consultations showed an OR of 3.25 (95% CI: 1.70-6.48) for death. Low birth weight (OR 8.42; 95% CI: 3.45-21.93); prematurity (OR 5.40; 95% CI: 2.22-13.88); malformations (OR 4.42; 95% CI: 1.37-12.43); and low Apgar score at the first (OR 6.65; 95% CI: 3.36-12.94) and at the fifth (OR 19.78; 95% CI: 9.12-44.50) minutes, were associated with death. CONCLUSION: Differing from other studies, socioeconomic conditions were not associated with neonatal death. Insufficient prenatal consultations, low Apgar score, prematurity, low birth weight, and malformations showed an association, reinforcing the importance of prenatal access universalization and its integration with medium and high-complexity neonatal care services.

Barriers to leisure-time physical activity in adults living in a low socioeconomic area of the Brazilian Southeast / Barreiras à prática de atividade física no tempo de lazer em adultos residentes em área de baixo nível socioeconômico do sudeste brasileiro

The aim of this study was to describe the main perceived barriers to engagement in leisure-time physical activity and associated factors among adults from the Ermelino Matarazzo district, Sao Paulo, Southeast, Brazil. Data were obtained from a population-based household survey conducted in 2007 involving 889 subjects (≥ 18 years). The long version of the International Physical Activity Questionnaire was used to identify physically inactive individuals. Open question about barriers was applied only for people inactive in leisure and content analysis was conducted to categorize the barriers. Descriptive analysis was performed using frequencies. Bivariate associations between the five most frequently reported barriers and sociodemographic variables, reported diagnoses of chronic diseases, nutritional status, working timing, travel time (to work and school), and television watching were determined using the chi-square test. Results showed that the five most prevalent barriers were lack of time (39.7%), lack of desire or motivation (18.4%), dislike exercising (6.3%), have an injury or disease (5.6%), and lack of money (3.6%). The vulnerable groups to lack of time were people married, young and middle aged, and with longer labor journey. Health problems were related by people with hypertension, diabetes, heart diseases, elderly, with low education and who did not have labor activ-ities. People who were not working, with low education and income, and with hypertension related more dislike of exercising. Lack of desire or motivation was most cited among people who watched television.These results are important to support community programs promoting leisure-time phys-ical activity in areas with low socioeconomic status

O objetivo deste estudo foi descrever as principais barreiras à prática de atividade física no tempo de lazer e fatores associados em adultos do distrito de Ermelino Matarazzo, município de São Paulo, Sudeste, Brasil. Utilizou-se dados de inquérito domiciliar de base populacional de 2007, com 889 sujeitos com 18 anos ou mais de idade. Aplicou-se Questionário Internacional de Atividades Físicas versão longa, questão aberta so-bre barreiras foi aplicada somente aos fisicamente inativos no lazer e análise de conteúdo conduzida para ca-tegorizá-las. Foram realizadas análises de associação bivariadas entre as cinco barreiras mais relatadas com variáveis sociodemográficas, autorrelato de doenças crônicas, estado nutricional, tempo de trabalho, tempo gasto com deslocamentos e hábito de assistir utilizando-se o teste qui-quadrado. Os resultados mostraram que as cinco barreiras mais prevalentes foram falta de tempo (39,7%), falta de vontade ou motivações (18,4%), não gostar de fazer exercícios (6,3%), problemas de saúde (5,6%) e falta de dinheiro (3,6%). Os grupos vul-neráveis à falta de tempo eram pessoas casadas, jovens e de meia-idade e com jornada de trabalho mais longa. Os problemas de saúde foram relatados por pessoas com hipertensão, diabetes, cardiopatias, idosos, pessoas com baixa escolaridade e que não trabalhavam. Pessoas com baixa escolaridade e renda, que não trabalham, e com hipertensão reportaram mais não gostar de se exercitar. A falta de vontade ou motivação foi mais citada entre pessoas que assistiam televisão. Esses resultados são importantes para embasar programas comunitários de promoção da atividade física no tempo de lazer em regiões de baixo nível socioeconômico

Assessment of the effectiveness of physical activity interventions in the Brazilian Unified Health System.

OBJECTIVE: To assess the effect of interventions on the levels of physical activity of healthy adults, users of the Brazilian Unified Health System and attended by the Family Health Strategy. METHODS: Non-randomized experimental study with 157 adults allocated in three groups: 1) physical exercise classes (n = 54), 2) health education (n = 54), 3) control (n = 49). The study lasted for18 months, with 12 months of interventions and six months of follow-up after intervention. Assessments took place at the beginning, in the 12 months, and in the 18 months of study. Physical activity has been assessed by questionnaires and accelerometry. For the analyses, we have used the intention-to-treat principle and generalized estimating equations. RESULTS: After 12 months, both intervention groups have increased the minutes of weekly leisure time physical activity and annual scores of physical exercise, leisure and transport-related physical activity. The exercise class group has obtained the highest average annual physical exercises score when compared to the other groups (p < 0.001). In the follow-up period, the exercise class group reduced its annual score (average: -0.3; 95%CI -0.5--0.1), while the health education group increased this score (average: 0.2; 95%CI 0.1-0.4). There have been no differences in the levels of physical activity measured by accelerometry. CONCLUSIONS: The interventions have been effective in increasing the practice of physical activity. However, we have observed that the health education intervention was more effective for maintaining the practice of physical activity in the period after intervention. We recommend the use of both interventions to promote physical activity in the Brazilian Unified Health System, according to the local reality of professionals, facilities, and team objectives. OBJETIVO: Avaliar o efeito de intervenções nos níveis de atividade física de adultos saudáveis, usuários do Sistema Único de Saúde e atendidos pela Estratégia de Saúde da Família. MÉTODOS: Estudo experimental, não randomizado, com 157 adultos alocados em três grupos: 1) classes de exercícios físicos (n = 54); 2) educação em saúde (n = 54); 3) controle (n = 49). O estudo teve duração de 18 meses, sendo 12 meses de intervenções e seis meses de acompanhamento pós-intervenção. As avaliações ocorreram no início, nos 12 e nos 18 meses de estudo. A atividade física foi avaliada por questionários e por acelerometria. Para as análises, utilizaram-se o princípio de intenção de tratar e equações de estimativas generalizadas. RESULTADOS: Após 12 meses, ambos os grupos de intervenção aumentaram os minutos semanais de atividade física no lazer e os escores anuais de exercícios físicos, de lazer e de deslocamento. O grupo das classes de exercícios físicos obteve maior média de escore anual de exercícios físicos em comparação com os outros grupos (p < 0,001). No período pós-intervenção, o grupo de classes de exercícios físicos reduziu o escore anual de exercícios físicos (média: -0,3; IC95% -0,5--0,1), enquanto o grupo de educação em saúde aumentou este escore (média: 0,2; IC95% 0,1-0,4). Não houve diferenças nos níveis de atividade física mensurados por acelerometria. CONCLUSÕES: As intervenções foram efetivas para aumentar a prática de atividade física. No entanto, observou-se que a intervenção de educação em saúde foi mais efetiva para a manutenção da prática de atividade física no período pós-intervenção. Recomenda-se a utilização de ambas as intervenções para a promoção da atividade física no Sistema Único de Saúde, de acordo com as realidades locais de profissionais, instalações e objetivos das equipes.
