Risk factors related to the global burden of disease in Brazil and its Federated Units, 2015

Time trends in subarachnoid haemorrhage mortality across the BRICS (Brazil, Russian Federation, India, China and South Africa): an age-period-cohort analysis for the GBD 2021

OBJECTIVES

Subarachnoid haemorrhage (SAH) is the third most prevalent subtype of stroke, representing a critical and potentially life-threatening cerebrovascular emergency. Given their large populations and diverse healthcare infrastructures, the BRICS (Brazil, Russian Federation, India, China and South Africa) nations play a pivotal role in the global SAH landscape. This investigation assesses the mortality trends of SAH in BRICS countries from 1982 to 2021.

DESIGN AND PARTICIPANTS

This study uses data from the Global Burden of Disease (GBD) 2021 public dataset to investigate the temporal trends in SAH mortality over four decades globally and within BRICS countries. The age-period-cohort (APC) model was employed to estimate net drift, local drift, age-specific curves and period (cohort) relative risks.

PRIMARY OUTCOME MEASURES

Mortality.

RESULTS

From 1982 to 2021, there was a 3.85% increase in global SAH deaths and a 59.46% decrease in age-standardised mortality rates. SAH mortality rates are increasing across various age groups in BRICS countries, except in China and the Russian Federation, where most age groups show increasing trends. The annual net drift in SAH mortality varied from a decrease of 5.62% in China to an increase of 0.31% in the Russian Federation. Countries demonstrated similar age-effect patterns, with risk decreasing as age increased. However, period and cohort effects varied, suggesting different control measures and temporal mortality trends.

CONCLUSIONS

Changing patterns of mortality from SAH in the BRICS countries over the last four decades vary. We suggest using local resources to step up SAH prevention. Healthcare for all ages, especially the vulnerable, should improve to prevent and treat SAH better.

Burden of disease attributable to risk factors: Estimates of the Global Burden of Disease from 1990 to 2021

OBJECTIVES

Analyze the burden of diseases attributable to risk factors (RF) in Brazil according to age, sex, and Brazilian states between 1990 and 2021.

METHODS

This study used data from the Global Burden of Disease study 1990 to 2021. The metrics used in this analysis included: mortality rates, disability-adjusted life years (DALYs) and Summary Exposure Value (SEV). A ranking of the risk factors was created by highlighting the changes between 1990 and 2021, according to sex, age group, and Brazilian state. RF were analyzed according to the Socio-Demographic Index (SDI).

RESULTS

Decline the risk factors of tobacco (-50.2 %), environmental: water, sanitation and hand washing (-58.0 %), and air pollution (-45.0 %), as well as an increase in the burden attributable to BMI (+78.4 %), alcohol consumption (+15.7 %). High systolic blood pressure ranked first in all states in 2021, followed by high blood glucose; tobacco ranking third in most states. The burden of diseases attributable to RFs in Brazil varied considerably between men and women, age groups, and states. Trends in the period from 1990 to 2021 showed a strong correlation with the SDI, better results being observed in states with higher SDI.

CONCLUSIONS

High blood pressure, high BMI and tobacco are the main risk factors for mortality and DALYs in 2021. The burden of disease has a high correlation with socio-economic indicator (SDI). It is important to strengthen public policies that promote healthy lifestyles, thus reducing disease and death.

Noncommunicable disease burden in Brazil and its states from 1990 to 2021, with projections for 2030

OBJECTIVES

The aim of this study was to analyse the burden of disease due to noncommunicable diseases (NCDs) between 1990 and 2021 in Brazil. In addition, this study compared mortality from NCDs with mortality from all causes and COVID-19, analysed NCD mortality trends and projections for 2030, and analysed NCD mortality rates and risk factors attributed to these deaths among the 27 states of Brazil.

STUDY DESIGN

Ecological studies.

METHODS

This study used the Global Burden of Disease study (GBD) database from 1990 to 2021. Premature deaths from four NCDs (neoplasms, cardiovascular disease, chronic respiratory diseases and diabetes mellitus) were analysed. The following metrics were used to analyse the burden of NCDs in Brazil: absolute number of deaths, proportional mortality, mortality rate, years of life lost due to premature death (YLL), years lived with disabilities (YLD) and disability-adjusted years of life lost due to premature death (DALY). For comparison between the years studied and states, age-standardised rates were used.

RESULTS

Finding from this study showed that there was increase in the proportion of premature deaths due to NCDs between 1990 and 2019 (29.4 % in 1990, 30.8 % in 2019), and a reduction in 2021 (24.7 %). The mortality rates, DALY and YLL from NCDs declined between 1990 and 2019 (-37.7 %, -34.5 % and -38.3 %, respectively); however, a stability in mortality rates, DALY, YLD, YLL was observed between 2019 and 2021 (-0.1 %, 0.7 %, -0.1 % and 0.8 %, respectively). Between 1990 and 2021, there was a decline in mortality rates, DALY and YLL for most states and an increase in YLD rates. However, results suggest that the Sustainable Development Goal (SDG) for the reduction in mortality from NCDs by one-third by 2030 will not be achieved. The main risk factors associated with premature death from NCDs in 2021 were high blood pressure, tobacco use, dietary risks, high body mass index (BMI) and high blood glucose levels. The correlation between sociodemographic index and percentage change in mortality rates was significant for the following total NCDs, cardiovascular disease, chronic respiratory disease, diabetes and neoplasms.

CONCLUSIONS

The current study highlights the importance of deaths from NCDs in Brazil and the worsening of mortality rates since 2016, as a result of austerity measures and the COVID-19 pandemic, which compromises the achievement of the SDG reduced mortality targets for NCDs. There was a reduction in risk factors for NCDs, mainly behavioural, although metabolic risk factors are of great concern and require new strategies to promote health, prevention and comprehensive care.

Examining the factors associated with functional capacity of community-dwelling older adults using the ICF framework: a cross-sectional study from the Frailty in Brazilian Older Adults Study (FIBRA)

BACKGROUND

There are many factors associated with functioning and disability in older adults and these relationships are not clear.

OBJECTIVE

To explore the factors associated with functional capacity of older adults using the framework of the International Classification of Functioning, Disability, and Health (ICF).

METHODS

This is a cross-sectional study with a dataset from a survey of 1 377 community-dwelling older adults (≥ 65 years) in a middle-income country. Three functional outcomes were selected to represent the functioning domains: 1) muscle strength for body function; 2) walking speed for activity; and 3) advanced activities of daily living (ADL) for participation. Demographic, clinical, and social information was selected to represent the domains of health conditions and contextual factors (i.e. personal and environmental factors). Multivariate models tested the impact of these factors on each outcome.

RESULTS

Depressive symptoms, age, and physical activity were associated with the three outcomes. Muscle strength was also associated with urinary incontinence, visual deficits, female sex, and employment. Walking speed was also associated with urinary incontinence, obesity, fractures due to falls, female sex, health professionals' visits, and walking aid devices. Advanced ADL were also associated with stroke, visual deficits, education, employment, health perception, social support, and walking aid devices.

CONCLUSION

Functional capacity of older adults is associated with some non-modifiable factors, such as age and sex. The modifiable factors must be addressed by health professionals and policymakers in the geriatric area, especially depression, obesity, physical inactivity, and social support.

Burden of non-communicable diseases and the achievement of the sustainable development goals in 2030 in Mercosur countries

OBJECTIVES

The aims of this article were to analyse the burden of NCDs and their RFs in the Mercosur countries between 1990 and 2019 and to project mortality trends for 2030.

STUDY DESIGN

Epidemiological study of time series.

METHODS

The present study used data from the Global Burden of Disease study. The absolute number of deaths, mortality rates, disability-adjusted life years, years of life lost, years lived with disability and the burden of premature mortality by NCD attributable to the RFs were evaluated. Projections were made up to 2030. Age-standardised rates were used to draw comparisons by years and by countries. The analysis was conducted using the RStudio software.

RESULTS

Between 1990 and 2019, a decrease was found in the premature mortality rates caused by NCDs in all the countries, except for Paraguay, which remained stable. When analysing premature mortality rates due to NCDs up to 2030, it was predicted that none of the countries would achieve the sustainable development goal of a one-third reduction in premature mortality by NCDs. Regarding the impacts of the RFs for NCDs, smoking, dietary risks, high blood pressure (BP) and high body mass index (BMI) were the main risks attributable to premature deaths due to NCDs.

CONCLUSIONS

The results showed that mortality rates are declining in Mercosur countries; however, none of the countries are predicted to achieve the sustainable development goal of a one-third reduction in mortality due to NCDs by 2030. In addition to access to adequate treatment, progress is required in public regulation actions to reduce RFs, such as smoking, dietary risks, high BP and high BMI.

[Occupational performance and application of the International Classification of Functioning (ICF) in a rehabilitation service]

OBJECTIVE

To describe the socio-demographic profile and analyze the occupational performance of users of a specialized rehabilitation service according to the International Classification of Functioning, Disability, and Health (ICF) model.

MATERIALS AND METHODS

Documentary and exploratory study, in which the medical records from 97 patients treated between 2013 and 2015, were assessed using the Canadian Occupational Performance Measure (COPM).

RESULTS

The age range of the patients was 14-83 years (average of 48.4 years), the majority being women (57.7%), married (43.3%), and retired (39.2%). Most patients had less than eight years of schooling (42.3%); 80.4% were sedentary; 12.4% smokers and 19.6% regularly consumed alcoholic beverages. Rotator cuff syndrome, stroke, and upper limb fracture were the most frequent diagnoses. The mean of occupational performance was 4.28 points (SD=1.84), and performance satisfaction was 4.43 points (SD=2.41). There were difficulties in self-care activities, functional mobility, productive activities and leisure and recreational activities. Regarding the components of the ICF, the Mobility domain obtained the highest number of categories cited by the users. In contrast, the Personal Care domain received the highest number of complaints.

CONCLUSION

The occupational performance of the patients presented more limitations in self-care and productive activities. The application of ICF to classify activities identified specific demands in five domains, Mobility, and Personal care being the most frequent. These results allow directing health actions towards the real needs of the patients and structuring professional practice.

Burden of Cardiovascular Diseases Attributable to Risk Factors in Portuguese-Speaking Countries: Data from the "Global Burden of Disease 2019" Study

BACKGROUND

The impact of risk factors (RF) on morbidity and mortality from cardiovascular disease (CVD) for most Portuguese-speaking countries (PSC) is little known.

OBJECTIVES

We aimed to analyze the morbidity and mortality from CVD attributable to RF and its variation, from 1990 to 2019, in PSC, based on estimates from the Global Burden of Disease (GBD) 2019 study.

METHODS

We evaluated changes in cardiovascular RF, mortality rates and age-standardized disability-adjusted life years (DALYs) between 1990 and 2019. The correlation between percentage changes in mortality rates and the sociodemographic index (SDI) of each PSC was evaluated by the Spearman method. A p-value <0.05 was considered statistically significant.

RESULTS

Elevated systolic blood pressure (SBP) was the main RF for mortality and DALYs for CVD for all PSC. Mortality from CVD showed a downward trend in 2019, more accentuated in Portugal (-66.6%, 95%CI -71.0 - -61.2) and in Brazil (-49.8%, 95%CI -52.5 - -47.1). There was a trend towards an inverse correlation between SDI and the percent change in mortality, which was significant for dietary risks (r=-0.70, p=0.036), high LDL cholesterol (r=-0.77, p=0.015) and high SBP (r=-0.74, p=0.023).

CONCLUSIONS

In addition to SBP, dietary and metabolic RF justified a greater variation in the burden of CVD correlated with SDI in the PSC, suggesting the need to adopt health policies adapted to the reality of each country, aiming to reduce their impact on population.

Food consumption markers and associated factors in Brazil: distribution and evolution, Brazilian National Health Survey, 2013 and 2019

This study objective was to describe the distribution of food consumption markers in Brazil per sociodemographic characteristics and its evolution from 2013 to 2019. Healthy food consumption markers (regular consumption of beans, fruits, vegetables, and fish, recommended consumption of red meat, and never replacing meals with snacks) and unhealthy food consumption markers (regular consumption of sweetened beverages and confectionery and excessive salt intake) were studied for adult participants of the Brazilian National Health Survey. The prevalence of food consumption markers was estimated according to sociodemographic characteristics and compared to data of 2013 and 2019. Most of the population regularly consumes beans, fruits, and vegetables, they also follows the recommendation to limit red meat consumption, and never replaces meals with snacks. The percentage of people who regularly consume sweetened beverages and perceive their salt intake as excessive is relatively low. The distribution of food consumption markers was associated with sex, age, income, race/skin color, area of dwelling, and schooling level. From 2013 to 2019, the prevalence of most food consumption markers declined, except for the regular consumption of fruits and recommended consumption of red meat, that increased 8.5% and 18.5%, respectively, and the regular consumption of vegetables, which did not vary. Healthy and unhealthy food consumption markers should be monitored to evaluate the effect of healthy eating policies implemented in the country.

[Urban geographic space and fruit and vegetable consumption: 2013 National Health Survey]

The aim of the study was to analyze the association between the urban geographic space and the regular consumption of fruit and vegetables in Brazil. It involved a population-based and cross-sectional study using data from the 2013 National Health Survey, considering 60,202 adults ≥18 years old. The dependent variables were regular fruit consumption (RFC) and regular vegetable consumption (RVC). The independent variable was the urban geographic space divided into three categories: capital, metropolitan region (MR) and interior. The Odds Ratio was calculated, adjusted by sociodemographic variables. Among women, the RFC was lower in MR (OR= 0.83; 95%CI: 0.73-0.94) and in the interior (OR= 0.68; 95%CI: 0.61-0.76), the same in men (RM: OR= 0.84; 95%CI: 0.75-0.93; Interior: OR= 0.78; 95%CI: 0.71-0.85). In most subcategories, the same was observed in the interior and the capital. There was no association with RVC and the urban geographic space in general, and when stratified in the subgroups even contradictory results were observed, because in some subgroups the RVC was higher in the capitals and lower elsewhere. Local aspects of production and distribution of these food products are considered when planning public policies that seek to promote consumption in the population.

Neighborhood environment is associated with unhealthy food intake in a Brazilian urban area

Unhealthy food intake is one of the main risk factors for morbidity and mortality for non-communicable diseases (NCDs), and is associated with multiple factors, including the neighborhood environment. The present study aimed to examine the association between the neighborhood context and unhealthy food intake in adults. This is a cross-sectional study, carried out in Belo Horizonte, Brazil. This study used the database of Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel), which was georeferenced and linked to a database with information on the physical and social realities of a neighborhood context. The administrative boundary of the basic health units (ABBHU) was used as a neighborhood unit. Unhealthy food intake was assessed by the regular consumption of meat with excess fat, soft drinks, and red meat, as well as the irregular consumption of fruits and vegetables. To characterize the physical and social realities of a neighborhood, this study used georeferenced data of establishments selling foods, population density, homicide rates, health vulnerability Index, and total income. For data analysis, multilevel logistic regression was used. The sample consisted of 5783 adults. It was observed that younger, males, people with a lower-level education, who were inactive during leisure time, who had abusive alcohol consumption, and who were current smokers, were associated with a greater chance of having an unhealthy food intake. After adjusting for individual characteristics, it was observed that living in ABBHU, with a low mean income and an extremely high vulnerability, increases the individual's chances of having an unhealthy food intake. An unhealthy food intake is partially explained by demographic characteristics and socioeconomic conditions in the neighborhood. The present study can contribute to improving the understanding of the importance of the urban environment in food choices.

Healthy and Safe School Cafeteria Program: a randomized controlled study

ABSTRACT Objective To assess the effect of an educational intervention program focused on health risk conditions, based on an assessment of the hygiene and quality of food sold in school cafeterias. Methods This is a controlled, parallel, randomized, two-arm, community study. Public and private schools with cafeterias were invited to participate. This study was conducted in 27 school cafeterias in northern and northwestern Rio Grande do Sul, a state in southern Brazil. Representatives of the school communities in the intervention group received an educational program consisting of 160-hour distance training. The most relevant outcomes were the assessment of the hygienic conditions and composition of the menus sold in school cafeterias. All outcomes were analyzed as intention-to-treat and per-protocol. For the analysis of continuous data with normal distribution, an analysis of covariance and the Generalized Linear Model were used. The level of statistical significance considered was p<0.05 for a 95% CI. Results No statistically significant difference was observed between the intervention group and the control group in the studied outcomes. There was a reduction of 76.2 points in the score for hygienic handling conditions (95% CI: -205 to 357; p=0.581). Regarding menu composition, the difference between groups was 0.48% (95% CI: -2.69 to 3.64; p=0.760) for ultra-processed foods, 0.23% (95% CI: -1.13 to 1.60; p=0.740) for processed foods, and 1.02% (95% CI: -2.59 to 4.64; p=0.581) for fresh foods. Conclusion There is not enough evidence to conclude that the intervention had a positive impact on any of the outcomes studied.

Trend of the Burden of Larynx Cancer in Brazil, 1990 to 2019

INTRODUCTION:

Larynx cancer is one of the most common head and neck cancers, whose main risk factors are smoking and alcohol use, and its occurrence and prognosis depend on adequate and timely preventive measures. This study aimed to investigate the burden of larynx cancer in Brazil and its states.

METHODS:

Using estimates from the Global Burden of Disease Study 2019, this study analyzed the trends of incidence, mortality, and disability-adjusted life years (DALYs) for larynx cancer between 1990 and 2019, besides the mortality-to-incidence ratio and the socio demographic index.

RESULTS:

Incidence and mortality due to larynx cancer in Brazil, which are approximately eight-fold higher for men, showed a declining trend between 1990 and 2019 (APPC: -0.4% and -1.0%, respectively). The DALYs also showed negative variation between 1990 and 2019 for both sexes in Brazil, mainly due to the decrease in premature deaths, with the greatest reduction in the state of São Paulo. For the states of Brazil in 2019, the higher age-standardized incidence rate (Rio Grande do Sul, 3.83 cases per 100,000 inhabitants) is twice the lowest rate (Piauí, 1.56 cases per 100,000 inhabitants).

CONCLUSIONS:

A fall in the burden of larynx cancer was observed in Brazil over the past 30 years, which may be attributed to a reduction in smoking and to an improvement in treatment. However, the regional inequalities in the country remain evident, especially for males. This data can guide public policy priorities to control the disease in Brazil.

[Transition of morbidity and mortality in Brazil: a challenge on the thirtieth anniversary of the SUS]

In 2020, the 30th anniversary of the publication of the Organic Laws of the Unified Health System was celebrated. Since then, the change in the profile of morbidity and mortality has been a challenge to management to ensure that the health services can attend the significant heterogeneity of approximately 6,000 municipalities. To achieve this, it is necessary to monitor the leading indicators of the country. The scope of this study was to present an overview of trends in mortality and morbidity in Brazil between 1990 and 2019. Data from the Study on the Global Burden of Disease was used to describe morbidity and mortality by major groupings (infectious diseases, chronic diseases, and external causes), according to gender and age groups. There was a reduction in morbidity and mortality in the period, irrespective of the cause or age group, albeit with a varied difference between the sexes depending on the cause. The contribution of chronic diseases increases with age, with a marked difference according to gender. The curves for mortality and years lost due to disability have a typical profile, with a different pattern of curves for men due to external causes, with marked excess mortality at young ages. The trend confirms the decline of indicators in a linear manner over the period.

[BMI variation, dietary patterns and physical activity among adults aged 21-44 years]

The scope of this article is to describe the association between BMI variation, eating patterns and physical activity among adults between 21 and 44 years of age from 2007 to 2012. It is a cross-sectional study using the VIGITEL database. Eating patterns were identified with Principal Components Analysis for the period from 2007 to 2012. Components with eigenvalues >1.0 were retained and factor loadings greater than |0.3| were highlighted. For each individual, a score was calculated per pattern. The Body Mass Index (ΔBMI) difference variable was then created. Linear regression with ΔBMI outcome and Poisson regression with obesity outcomes were conducted. Four eating patterns were retained: Prudent, Transition, Western and Traditional. After multivariate adjustment, ΔBMI was inversely associated with the habit of leisure-time physical activity. Obesity revealed a positive association with the Western pattern, watching television ≥3 hours a day and physical inactivity. Obesity was inversely associated with the Prudent pattern, the Traditional pattern, the practice of leisure-time physical activity and the habit of physical activity at work. Eating patterns based on unprocessed and minimally processed foods and practice of physical activity are protective factors against obesity.

Prevalence and sociodemographic factors associated with heavy drinking in Brazil: cross-sectional analyses of the National Health Survey

OBJECTIVE

This article aims to characterize the heavy drinking behavior in the Brazilian population, using data from the two editions of the "National Health Survey" (PNS), 2013 and 2019.

METHODS

The sample sizes in 2013 and 2019 were 60,202 and 88,943 individuals aged 18 years or older, respectively. The prevalence of the habit of heavy drinking (defined as 8 or more doses per week for women, and 15 or more doses for men) was estimated, and the confidence intervals were defined by sex, age group, schooling, skin color/race, marital status and household status (urban/rural). Poisson regression models were used to compare prevalence rates.

RESULTS

6.1% of Brazilians were heavy drinkers in 2013, and 7.3% in 2019. In the two editions of the PNS there was a gradient of reduction in heavy drinking throughout life, being the highest prevalence among young adults, men, with low schooling, single and living in the urban area.

CONCLUSIONS

The high prevalence rates expose the need to consider the habit of heavy drinking as a risk factor for the health of the Brazilian population, and the urgency to adopt strategies to reduce it.

Fruit and vegetable consumption, leisure-time physical activity and binge drinking in Belo Horizonte, Brazil, according to the Health Vulnerability Index

OBJECTIVE

To estimate the prevalence of fruit and vegetable consumption, practice of leisure time physical activity (LTPA) and binge drinking for small areas of Belo Horizonte, Minas Gerais.

METHODS

Ecological study conducted with data from the Surveillance System for Risk and Protection Factors for Noncommunicable Diseases by Telephone Survey (Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico - Vigitel). The prevalence of risk and protection factors from 2006 to 2013 were estimated and the 95% confidence intervals calculated. "Small areas" corresponded to the municipality division into four strata of health risk classification given by the Health Vulnerability Index 2012 (Índice de Vulnerabilidade à Saúde - IVS).

RESULTS

The mean prevalences for the period were: about 42% of regular intake of fruit and vegetable, 34.7% of leisure time activity and 20.4% of binge drinking. The prevalence of fruit and vegetable consumption was higher in low-risk areas (58.5%; 95%CI 56.8 - 60.2) and lower in very high-risk areas (32.3%; 95%CI 27.7 - 36.9). The practice of LTPA was higher in low-risk areas (40.8%; 95%CI 38.9 - 42.8) and lower in very high risk (25.2%; 95%CI 20.6 - 29.9). Binge drinking was higher in low-risk areas (22.9%; 95%CI 21.7 - 24.2) compared to very high-risk areas (14.3%; 95%CI 11.4 - 17.3).

CONCLUSION

It was identified a gradient in the distribution of risk and protection factors for noncommunicable diseases in Belo Horizonte according to the risk classification. This information can support programs aimed at reducing health inequalities, especially in the most vulnerable areas.

Challenges for obesity management in a unified health system: the view of health professionals

BACKGROUND

Obesity is an increasingly prevalent chronic condition. Its multiple causes and the complexity of its treatment pose challenges for health professionals.

OBJECTIVE

To explore and describe the challenges for obesity management in the Brazilian Unified Health System according to health professionals.

METHODS

An exploratory quantitative web-based study, carried out in 2018 with health professionals, developed from the first stage of a national project that aims to examine the management of obesity in Brazil. The questionnaire was self-applied. Invitations to participate in the research were sent by the Ministry of Health, Health Department of Minas Gerais and members of the research group. We collected data on sex, age, professional category, region and level of care. The challenges were investigated using a Likert scale and categorized into structure and work process.

RESULTS

We evaluated 1323 professionals, of which about 45% were dietitians, 90.2% were women, and 83.1% self-reported working in primary health care. The main barriers cited included a high demand for curative and individual assistance, the presence of comorbidities, and the absence or insufficient access to instructional materials, professional qualification and lack of support.

CONCLUSION

Obesity management is a critical challenge for all professionals. Barriers were related to the work process and structural aspects and reinforce the need to empower health teams. We propose that permanent education activities should be established, as well as the development of instructional materials that are applicable to routine work. Finally, the results may be used to develop policies and strategies to improve obesity management.

Program for Healthier School Cafeterias in Rio Grande do Sul, Brazil: Protocol for a Community-Based Randomized Trial

Background

School cafeterias can promote poor eating habits, as these retail outlets have a variety of foods considered to be nonnutritive and unhealthy. However, despite the need for effective preventive strategies, there is still disagreement on the best approach due to the lack of evidence on interventions to prevent and treat obesity in the school settings.

Objective

We aim to verify the efficacy of an educational intervention program to improve the hygienic conditions and the composition of the menu offered in school cafeterias in the state of Rio Grande do Sul, Brazil.

Methods

We will conduct a randomized, parallel, two-arm, community-based controlled study. Elementary and high schools, both public and private, in the State of Rio Grande do Sul, Brazil, that have a cafeteria will be eligible. Schools will be recruited and randomly assigned to the intervention (n=27) or control (n=27) group. The intervention group will receive an educational intervention program based on the guidelines issued by the Ministry of Health of Brazil, consisting of a 160-hour distance-learning qualification course, for 10 weeks, and using the Moodle platform and WhatsApp app. The intervention targets the owners and people in charge of the cafeterias, food handlers, principals, vice principals, teachers, pedagogical coordinators, dietitians, representatives of students' parents, and students over 16 years old. Meanwhile, the control group will receive only a printed copy of the book containing the guidelines used. The efficacy of the intervention will be determined by the hygienic conditions of the cafeteria and the composition of the menu offered, also considering the levels of processing of food sold. All outcomes will be analyzed as intention-to-treat and per-protocol. We will use covariance analysis or a generalized linear model for continuous data and ordinal logistic regression for ordinal categorical data. The level of statistical significance considered will be P<.05 for a 95% CI.

Results

This project was funded in early 2018. We administered the intervention program in 2019. All data have already been collected, and we are analyzing the data. The results are expected in 2021.

Conclusions

To our knowledge, this may be the first randomized controlled study in school cafeterias held in Brazil. The results will provide evidence for the formulation of public food and nutritional security policies and for the development of effective strategies to provide safe and healthy school meals.

Perfil alimentar e inatividade física em mulheres universitárias na cidade de Brasília

Resumo Objetivo Analisar a associação entre perfil alimentar, atividade física e estado nutricional entre mulheres universitárias. Método Estudo transversal com 1500 mulheres. O questionário abordava questões sobre a vigilância de fatores de risco e proteção para doenças crônicas. As associações foram analisadas pelo teste qui-quadrado e análise de correspondência múltipla. Resultados Das 1500 mulheres, 64,3% tinham entre 20 e 29 anos. Aquelas fisicamente ativas consumiram mais frutas (p<0,01), salada (p<0,01) e vegetais/verduras (p<0,01), enquanto as fisicamente inativas consumiram mais refrigerantes (p<0,01), carne com gordura visível (p=0,03) e leite com gordura (p=0,04). As mulheres fisicamente inativas também apresentaram maior prevalência de diabetes mellitus (p<0,01), colesterol elevado (p<0,01) e dislipidemia (p=0,04). Conclusão e implicação para a prática As universitárias apresentaram comportamentos de risco a sua saúde, onde o consumo de álcool, baixo consumo de alimentos saudáveis e a alta prevalência de inatividade física contribuíram para o aumento dos fatores de risco para doenças crônicas. Ações preventivas com a participação de uma equipe multidisciplinar ajudará na melhora da saúde no ambiente acadêmico.

Mortality by road traffic injuries in Brazil (2000-2016): capital cities versus non-capital cities

OBJECTIVES

To compare the magnitude and trend of mortality by road traffic injuries (RTI) in the capitals and other municipalities of each Brazilian state between 2000 and 2016.

METHODS

A time series analysis of mortality rates by RTI standardized by age was performed, comparing the capitals and the cluster of non-capital municipalities in each state. Data on deaths were obtained from the Sistema de Informações sobre Mortalidade (SIM - Mortality Information System). RTI deaths were considered to be those, whose root cause was designated by ICD-10 codes V01 to V89, with redistribution of garbage codes. To estimate mortality rates, we used the population projections of the Brazilian Institute of Geography and Statistics (IBGE) from 2000 to 2015 and the population estimated by polynomial interpolation for 2016. The trend analysis was performed using the Prais-Winsten method, using the Stata 14.0 program.

RESULTS

There were 601,760 deaths due to RTI in the period (114,483 of residents in capital cities). Mortality by RTI did not present an increasing trend in any of the Capitals in the period under study. Among non-capital municipalities, the trend was growing in 14 states. The greatest increase was observed in Piaui (AIR = 7.50%; 95%CI 5.50 - 9.60). There was a decreasing trend in RTI mortality in 14 capitals, among which Curitiba showed the greatest decrease (AIR = -4.82%; 95%CI -6.61 - -2.92). Only São Paulo and Rio Grande do Sul showed a decreasing trend in mortality by RTI in non-capital cities (AIR = 2.32%; 95%CI -3.32 - -1.3 and AIR = 1.2%, 95%CI -2.41 - 0.00, respectively).

CONCLUSIONS

We conclude that RTI mortality rates in non-capital cities in Brazil showed alarming trends when compared with those observed in capital cities. The development of effective traffic safety actions is almost always limited to Brazilian capitals and large cities. Municipalities with higher risk should be prioritized to strengthen public policies for prevention and control.

Trends in prevalence, mortality, and morbidity associated with high systolic blood pressure in Brazil from 1990 to 2017: estimates from the "Global Burden of Disease 2017" (GBD 2017) study

Background

Hypertension remains the leading risk factor for cardiovascular disease (CVD) worldwide, and its impact in Brazil should be assessed in order to better address the issue. We aimed to describe trends in prevalence and burden of disease attributable to high systolic blood pressure (HSBP) among Brazilians ≥ 25 years old according to sex and federal units (FU) using the Global Burden of Disease (GBD) 2017 estimates.

Methods

We used the comparative risk assessment developed for the GBD study to estimate trends in attributable deaths and disability-adjusted life-years (DALY), by sex, and FU for HSBP from 1990 to 2017. This study included 14 HSBP-outcome pairs. HSBP was defined as ≥ 140 mmHg for prevalence estimates, and a theoretical minimum risk exposure level (TMREL) of 110–115 mmHg was considered for disease burden. We estimated the portion of deaths and DALYs attributed to HSBP. We also explored the drivers of trends in HSBP burden, as well as the correlation between disease burden and sociodemographic development index (SDI).

Results

In Brazil, the prevalence of HSBP is 18.9% (95% uncertainty intervals [UI] 18.5–19.3%), with an annual 0.4% increase rate, while age-standardized death rates attributable to HSBP decreased from 189.2 (95%UI 168.5–209.2) deaths to 104.8 (95%UI 94.9–114.4) deaths per 100,000 from 1990 to 2017. In spite of that, the total number of deaths attributable to HSBP increased 53.4% and HSBP raised from 3rd to 1st position, as the leading risk factor for deaths during the period. Regarding total DALYs, HSBP raised from 4th in 1990 to 2nd cause in 2017. The main driver of change of HSBP burden is population aging. Across FUs, the reduction in the age-standardized death rates attributable to HSBP correlated with higher SDI.

Conclusions

While HSBP prevalence shows an increasing trend, age-standardized death and DALY rates are decreasing in Brazil, probably as results of successful public policies for CVD secondary prevention and control, but suboptimal control of its determinants. Reduction was more significant in FUs with higher SDI, suggesting that the effect of health policies was heterogeneous. Moreover, HSBP has become the main risk factor for death in Brazil, mainly due to population aging.

The burden of non-communicable diseases attributable to high BMI in Brazil, 1990-2017: findings from the Global Burden of Disease Study

BACKGROUND

The prevalence and burden of disease resulting from obesity have increased worldwide. In Brazil, more than half of the population is now overweight. However, the impact of this growing risk factor on disease burden remains inexact. Using the 2017 Global Burden of Disease (GBD) results, this study sought to estimate mortality and disability-adjusted life years (DALYs) lost to non-communicable diseases caused by high body mass index (BMI) in both sexes and across age categories. This study also aimed to describe the prevalence of overweight and obesity throughout the states of Brazil.

METHODS

Age-standardized prevalence of overweight and obesity were estimated between 1990 and 2017. A comparative risk assessment was applied to estimate DALYs and deaths for non-communicable diseases and for all causes linked to high BMI.

RESULTS

The prevalence of overweight and obesity increased during the period of analysis. Overall, age-standardized prevalence of obesity in Brazil was higher in females (29.8%) than in males (24.6%) in 2017; however, since 1990, males have presented greater rise in obesity (244.1%) than females (165.7%). Increases in prevalence burden were greatest in states from the North and Northeast regions of Brazil. Overall, burden due to high BMI also increased from 1990 to 2017. In 2017, high BMI was responsible for 12.3% (8.8-16.1%) of all deaths and 8.4% (6.3-10.7%) of total DALYs lost to non-communicable diseases, up from 7.2% (4.1-10.8%), and 4.6% (2.4-6.0%) in 1990, respectively. Change due to risk exposure is the leading contributor to the growth of BMI burden in Brazil. In 2017, high BMI was responsible for 165,954 deaths and 5,095,125 DALYs. Cardiovascular disease and diabetes have proven to be the most prevalent causes of deaths, along with DALYs caused by high BMI, regardless of sex or state.

CONCLUSIONS

This study demonstrates increasing age-standardized prevalence of obesity in all Brazilian states. High BMI plays an important role in disease burdens in terms of cardiovascular diseases, diabetes, and all causes of mortality. Assessing levels and trends in exposures to high BMI and the resulting disease burden highlights the current priority for primary prevention and public health action initiatives focused on obesity.

Trends in mortality due to non-communicable diseases in the Brazilian adult population: national and subnational estimates and projections for 2030

BACKGROUND

Monitoring and reducing premature mortality due to non-communicable diseases (NCDs) is a global priority of Agenda 2030. This study aimed to describe the mortality trends and disability-adjusted life years (DALYs) lost due to NCDs between 1990 and 2017 for Brazil and to project those for 2030 as well as the risk factors (RFs) attributed deaths according to estimates of the Global Burden of Disease Study.

METHODS

We analyzed cardiovascular diseases, chronic respiratory diseases, neoplasms, and diabetes, and compared the mortality rates in 1990 and 2017 for all of Brazil and states. The study used the definition of premature mortality (30-69 years) that is used by the World Health Organization. The number of deaths, mortality rates, DALYs, and years of life lost (YLL) were used to compare 1990 and 2017. We analyzed the YLL for NCDs attributable to RFs.

RESULTS

There was a reduction of 35.3% from 509.1 deaths/100,000 inhabitants (1990) to 329.6 deaths/100,000 inhabitants due to NCDs in 2017. The DALY rate decreased by 33.6%, and the YLL rate decreased by 36.0%. There were reductions in NCDs rates in all 27 states. The main RFs related to premature deaths by NCDs in 2017 among women were high body mass index (BMI), dietary risks, high systolic blood pressure, and among men, dietary risks, high systolic blood pressure, tobacco, and high BMI. Trends in mortality rates due to NCDs declined during the study period; however, after 2015, the curve reversed, and rates fluctuated and tended to increase.

CONCLUSION

Our findings highlighted a decline in premature mortality rates from NCDs nationwide and in all states. There was a greater reduction in deaths from cardiovascular diseases, followed by respiratory diseases, and we observed a minor reduction for those from diabetes and neoplasms. The observed fluctuations in mortality rates over the last 3 years indicate that if no further action is taken, we may not achieve the NCD Sustainable Development Goals. These findings draw attention to the consequences of austerity measures in a socially unequal setting with great regional disparities in which the majority of the population is dependent on state social policies.

Monitoring the progress of health-related sustainable development goals (SDGs) in Brazilian states using the Global Burden of Disease indicators

BACKGROUND

Measuring the Global Burden of Disease (GBD) has been the key to verifying the evolution of health indicators worldwide. We analyse subnational GBD data for Brazil in order to monitor the performance of the Brazilian states in the last 28 years on their progress towards meeting the health-related SDGs.

METHODS

As part of the GBD study, we assessed the 41 health-related indicators from the SDGs in Brazil at the subnational level for all the 26 Brazilian states and the Federal District from 1990 to 2017. The GBD group has rescaled all worldwide indicators from 0 to 100, assuming that for each one of them, the worst value among all countries and overtime is 0, and the best is 100. They also estimate the overall health-related SDG index as a function of all previously estimated health indicators and the SDI index (Socio-Demographic Index) as a function of per capita income, average schooling in the population aged 15 years or over, and total fertility rate under the age of 25 (TFU25).

RESULTS

From 1990 to 2017, most subnational health-related SDGs, the SDG and SDI indexes improved considerable in most Brazilian states. The observed differences in SDG indicators within Brazilian states, including HIV incidence and health worker density, increased over time. In 2017, health-related indicators that achieved good results globally included the prevalence of child wasting, NTD, household air pollution, conflict mortality, skilled birth attendance, use of modern contraceptive methods, vaccine coverage, and health worker density, but poor results were observed for child overweight and homicide rates. The high rates of overweight, alcohol consumption, and smoking prevalence found in the historically richest regions (i.e., the South and Southeast), contrast with the high rates of tuberculosis, maternal, neonatal, and under-5 mortality and WASH-related mortality found in the poorer regions (i.e., the North and Northeast).

CONCLUSIONS

The majority of Brazil's health-related SDG indicators have substantially improved over the past 28 years. However, inequalities in health among the Brazilian states and regions remain noticeable negatively affecting the Brazilian population, which can contribute to Brazil not achieving the SDG 2030 targets.

Trends in prevalence and mortality burden attributable to smoking, Brazil and federated units, 1990 and 2017

BACKGROUND

The present study sought to analyze smoking prevalence and smoking-attributable mortality estimates produced by the 2017 Global Burden of Disease Study for Brazil, 26 states, and the Federal District.

METHODS

Prevalence of current smokers from 1990 to 2017 by sex and age was estimated using spatiotemporal Gaussian process regression. Population-attributable fractions were calculated for different risk-outcome pairs to generate estimates of smoking-attributable mortality. A cohort analysis of smoking prevalence by birth-year cohort was performed to better understand temporal age patterns in smoking. Smoking-attributable mortality rates were described and analyzed by development at state levels, using the Socio-Demographic Index (SDI). Finally, a decomposition analysis was conducted to evaluate the contribution of different factors to the changes in the number of deaths attributable to smoking between 1990 and 2017.

RESULTS

Between 1990 and 2017, prevalence of smoking in the population (≥ 20 years old) decreased from 35.3 to 11.3% in Brazil. This downward trend was seen for both sexes and in all states, with a marked reduction in exposure to this risk factor in younger cohorts. Smoking-attributable mortality rates decreased by 57.8% (95% UI - 61.2, - 54.1) between 1990 and 2017. Overall, larger reductions were observed in states with higher SDI (Pearson correlation 0.637; p < 0.01). In Brazil, smoking remains responsible for a considerable amount of deaths, especially due to cardiovascular diseases and neoplasms.

CONCLUSIONS

Brazil has adopted a set of regulatory measures and implemented anti-tobacco policies that, along with improvements in socioeconomic conditions, have contributed to the results presented in the present study. Other regulatory measures need to be implemented to boost a reduction in smoking in order to reach the goals established in the scope of the 2030 United Nations Agenda for Sustainable Development.

Factors associated with self-reported exposure to chemical substances at work in Brazil: results from the National Health Survey, 2013

OBJECTIVE

To describe the prevalence of self-reported exposure to chemical substances at work and its associated factors in a sample of Brazilian adults that participated in the National Health Survey, conducted between 2013 and 2014.

METHODS

Our sample consisted of adults aged 18 years or older that answered question E1 of module E: “In the week of July 21-27, 2013 (reference week), did you work as regular employee or intern for at least an hour in any activity paid with cash?” Sociodemographic data, situation and health behaviors were analyzed with single and multivariate binary logistic regression. The model was adjusted by the variables of all groups, adopting a 5% significance level. The values of odds ratio (OR) and respective confidence intervals were obtained.

RESULTS

Women (OR = 0.74; 95%CI 0.66–0.82) had a lower chance of exposure to chemicals. The highest chances were observed in groups with no instruction or that attended up to middle-school (OR = 1.77; 95%CI 1.50–2.08), high school (OR = 1.62; 95%CI 1.37–1.91), age between 25 and 54 years (OR = 1.26; 95%CI 1.07–1.48), current smokers (OR = 1.21; 95%CI 1.07–1.37), who reported tiredness (OR = 1.35; 95%CI 1.21–1.50), hearing difficulties (OR = 1.24; 95%CI 1.04–1.48) and who reported having suffered an accident at work (OR = 2.00; 95%CI 1.57–2.54).

CONCLUSIONS

The unprecedented results cover the entire workforce. Positive associations with hearing loss, smoking and history of work accidents are consistent, as well as the inverse association with education level and gender differences. The absence of association with asthma was surprising. To fill gaps in investigations on chronic non-communicable diseases, we suggested improving the PNS collection instrument in the occupational dimension.

Trend in dietary patterns among adults from Brazilian state capitals

OBJECTIVE

To describe and analyze the trend in dietary patterns followed by the adult population aged 18 to 44 years living in Brazilian state capitals between 2007 and 2012.

METHODS

We identified dietary patterns using the principal component analysis (PCA). The analysis retained components with eigenvalues >1.0 and highlighted factor loadings (FLs) >|0.2|. After the identification of four patterns, they received standardized scores with zero mean. The mean scores were presented for each pattern according to gender, age group, schooling, and year of data collection. We estimated the temporal variation of the mean scores of the patterns by linear regression.

RESULTS

We identified four dietary patterns in the population: prudent, transition, western, and traditional. We found an increasing trend in the mean score of the patterns: prudent, western, and traditional and a reduced mean score in the transition pattern. Individuals with better education showed greater adherence to the prudent pattern. Less-educated individuals presented higher adherence to the western and traditional patterns.

CONCLUSION

Public policies targeting the population with lower schooling and men are necessary due to their greater adherence to unhealthy dietary patterns.

Workers' Healthcare Assistance Model (WHAM): Development, Validation, and Assessment of Sustainable Return on Investment (S-ROI)

The present study aimed to present and validate the Worker´s Healthcare Assistance Model (WHAM), which includes an interdisciplinary approach to health risk management in search of integral and integrated health, considering economic sustainability. Through the integration of distinct methodological strategies, WHAM was developed in the period from 2011 to 2018, in a workers' occupational health centre in the oil industry in Bahia, Brazil. The study included a sample of 965 workers, 91.7% of which were men, with a mean age of 44.9 years (age ranged from 23 to 73 years). The Kendall rank correlation coefficient and hierarchical multiple regression analysis were used for the validation of WHAM. The assessment of sustainable return on investment (S-ROI) was made using the WELLCAST ROI™ decision support tool, covering workers with heart disease and diabetes. WHAM can be considered an innovative healthcare model, as there is no available comparative model. WHAM is considered robust, with 86% health risk explanatory capacity and with an 85.5% S-ROI. It can be concluded that WHAM is a model capable of enhancing the level of workers' health in companies, reducing costs for employers and improving the quality of life within the organization.

[Feeding and nutrition efforts in the context of primary healthcare in BrazilMedidas relativas a la alimentación y la nutrición en la atención primaria de salud en Brasil]

In Brazil, the promotion, protection, and recovery of health are among the initiatives provided by the public and universal Unified Health System (SUS). The primary healthcare level (PHC), the preferred point of access to the system, plays the role of coordinating and ordinating health care services and actions in the network. In the context of PHC, feeding and nutrition efforts must be aligned with National Feeding and Nutrition Policy (PNAN) guidelines and may be supported by feeding and nutritional surveillance actions. Data from PHC information systems and population surveys show that excess weight affects more than half the adult population of Brazil, and that consumption of ultra-processed foods is on the rise. This scenario requires that health care teams be prepared to prioritize initiatives for users with chronic diseases, using risk stratification, stabilization of the disease, and enhancement of supported self-care with a focus on diet and physical activity. At the same time, considering the country's epidemiological profile, teams must carry out initiatives to fight undernutrition and prevent anemia and hypovitaminosis A to address the multiple burden of malnutrition. The present article describes the current scenario of feeding and nutrition initiatives implemented at the PHC level in Brazil via the SUS.

INDICATORS OF ADIPOSITY ASSOCIATED WITH LOW BODY ESTEEM IN ADOLESCENTS

OBJECTIVE

To investigate the association between weight status and anthropometric indicators of adiposity with body esteem.

METHODS

Cross-sectional study including 305 adolescents from a public school in Rio de Janeiro, Brazil. Data were collected by a self-administered questionnaire and anthropometric measurements. The Body-Esteem Scale for Adolescents and Adults was used to evaluate total body esteem and the "appearance", "weight", and "attribution" domains. Body mass index (weight/stature2) was applied to assess weight status and waist circumference, the central body adiposity. The association between indicators of adiposity and body esteem was assessed using Student's t-test or Mann-Whitney's test and linear regression models, stratified by sex and age group.

RESULTS

Overweight/obesity was observed in 46% of younger adolescents (10 to 13 year-old girls, 10 to 14 year-old boys), 38% of older boys (15 to 18 year old), and 16% of older girls (14 to 18 year old). For both boys and girls in the younger age group, body mass index and waist circumference (as continuous variables) were inversely associated with total body esteem and weight domain. Overweight/obesity was associated with the appearance body esteem domain only among younger male adolescents; no association was found between either the body mass index or waist circumference and the attribution domain.

CONCLUSIONS

Indicators of adiposity were associated with low body esteem. These findings underscore the fact that considering adolescents' feelings concerning their body and appearance is important to promote a healthy control of weight.

Addressing chronic noncommunicable diseases in primary health care in Goiás, Brazil: a descriptive study, 2012 and 2014

OBJECTIVE

To compare primary health care (PHC) actions taken to care for chronic non-communicable diseases (NCDs) in the state of Goiás, Brazil, between 2012 and 2014.

METHODS

This was a descriptive study using secondary data from the National Program for Improving Primary Care Access and Quality (PMAQ-AB). The proportions of teams performing actions to address NCDs were compared between PMAQ-AB cycles I and II using the McNemar test for paired samples.

RESULTS

Seventeen of the 20 variables studied showed a proportional increase between the two cycles: from 16.0% to 32.1% of teams that practiced all care management actions, from 21.5% to 35.2% of those that practiced all health promotion actions and from 22.2% to 39.8% of teams that practiced all activities at school.

CONCLUSION

PHC actions to address NCDs in Goiás were strengthened between the two PMAQ-AB cycles.

Application of the ≤ 10:1 carbohydrate to fiber ratio to identify healthy grain foods and its association with cardiometabolic risk factors

PURPOSE

Optimal metrics to assess healthfulness of carbohydrate-rich products are not well established. We investigated how the content per 10 g of carbohydrate of at least 1 g of fiber (≤ 10:1-ratio) related to nutritional quality in grain foods as well as cardiometabolic risk factors in São Paulo, Brazil.

METHODS

Data were from the cross-sectional population-based study 2015 Health Survey of São Paulo, including a probabilistic sample of urban residents in the city. Participants (n = 1188) aged 20 + years completed a 24-h dietary recall and a subsample of 603 participants had blood samples, anthropometrics, and blood pressure measurements collected, and answered a second 24-h recall. Energy and nutrient contents of grain foods meeting or not meeting the ≤ 10:1-ratio were evaluated using linear regression models. The association between consumption (percent energy, %E) of grain foods meeting the ≤ 10:1-ratio and cardiometabolic risk factors were investigated using linear regression models.

RESULTS

Foods meeting the ≤ 10:1-ratio had less available carbohydrate (- 3.0 g/serving), total sugar (- 7.4 g/serving), added sugar (- 7.2 g/serving) and saturated fat (- 0.7 g/serving), and more dietary fiber (+ 3.5 g/serving), protein (+ 2.1 g/serving), potassium (+ 100.1 mg/serving), iron (+ 0.9 mg/serving), selenium (+ 4.2 µg/serving), magnesium (+ 38.7 mg/serving), and zinc (+ 1.1 mg/serving). Each increase in 1%E consumption of grain foods meeting the ≤ 10:1-ratio was associated with lower levels of blood triacylglycerol (- 10.7%), the triacylglycerol/high-density lipoprotein cholesterol ratio (- 14.9%), fasting insulin (- 13.6%), and homeostasis model assessment for insulin resistance (- 14.0%).

CONCLUSION

The ≤ 10:1-ratio identified grain foods with higher nutritional quality and higher intakes of these foods were associated with cardiometabolic risk factors related to atherogenic dyslipidemia and insulin resistance.

Self-reported medical diagnosis of heart disease and associated risk factors: National Health Survey

OBJECTIVE

To analyze the risk factors associated with the self-reported medical diagnosis of heart disease in Brazil.

METHODS

This is a cross-sectional study, analyzing information from 60,202 adult participants of the Brazilian National Health Survey in 2013. Heart disease was defined by self-reported medical diagnosis of heart disease. We analyzed associations between the occurrence of disease and sociodemographic characteristics, health conditions and lifestyle. A hierarchical binary logistic regression model was used.

RESULTS

The prevalence of self-reported diagnosis of heart disease in Brazil was 4.2% (confidence interval of 95% [95%CI] 4.0 ‒ 4.3) and was associated with females (odds ratio [OR] = 1.1; 95%CI 1.1 ‒ 1.1), people 65 years old or older (OR = 4.7; 95%CI 3.3 ‒ 5.6), poor or very poor health conditions (OR = 4.1; 95%CI 3.5 ‒ 4.6) and fair health conditions (OR = 2.4; 95%CI 2.2 ‒ 2.7), hypertensive individuals (OR = 2.4; 95%CI 2.2 ‒ 2.7), those with increased cholesterol (OR = 1.6; 95%CI 1.5 ‒ 1.8), overweight individuals (OR = 1.5; 95%CI 1.4 ‒ 1.8) and obese individuals (OR = 2.0; 95%CI 1.7 ‒ 2.2), sedentary behavior (OR = 1.5; 95%CI 1.02 ‒ 2.1), former smokers (OR = 1.4; 95%CI 1.3 ‒ 1.6) or current smokers (OR = 1.2; 95%CI 1.03 ‒ 1.3) and the consumption of fruits and vegetables 5 or more days each week (OR = 1.5; 95%CI 1.1 ‒ 1.5).

CONCLUSION

The importance of knowledge on the prevalence of heart disease and associated risk factors in the present Brazilian epidemiological context must be emphasized because it guides actions to control and prevent cardiovascular diseases, the leading cause of death in Brazil and worldwide.

Trends in the number of traffic accident victims on Brazil's federal highways before and after the start of the Decade of Action for Road Safety

This study aimed to analyze the trend in the number of fatalities, severe injuries, and minor injuries from traffic accidents on Brazil's federal highways according to the country's major geographic regions before and after the start of the Decade of Action for Road Safety (DARS). This was an interrupted time series study of data on accidents with fatal or injured victims provided by the Brazilian Federal Highway Police from 2007 to 2017. The Prais-Winsten method was used to calculate the monthly percentage change (MPC) in the number of fatalities, severe injuries, and minor injuries. Before the DARS, there was an upward monthly trend in the number of fatalities in these accidents in the country as a whole (MPC 0.71%) and in all five regions, especially in the South (MPC 1.01%) and Central-West (MPC 0.84%). There was an inverse trend after the start of the DARS, with a significant decrease in Brazil as a whole (MPC -1.24%) and in the major geographic regions. For each person that dies in an accident on a federal highway, at least 12 others suffer non-fatal injuries. There was an upward trend in the number of victims with severe injuries (MPC 0.53%) and minor injuries (MPC 0.8%) in Brazil and in the major geographic regions in the period prior to the DARS. After the start of the DARS, there was a significant downward trend in the absolute frequencies of these outcomes at the national and regional levels. In conclusion, before the DARS, there was an upward monthly trend in the number of fatal and injured victims of traffic accidents on Brazil's federal highways. After the start of the DARS, in 2011, there was an inverse trend, namely a decline in these outcomes in the country.

Development and Validation of an Interdisciplinary Worker's Health Approach Instrument (IWHAI)

The present study aimed to develop and validate an Interdisciplinary Worker's Health Approach Instrument (IWHAI). The development stage comprised a group of 10 professionals, including physicians, nurses, nutritionists, dentists and physical educators, as well as a judges' committee, composed by 19 recognized experts in the area of worker's health (WH). For the validation of the IWHAI, the Spearman's correlation coefficient (rs) was calculated, the factor analysis to the instrument was applied, and the Cronbach's alpha (α) and the Intraclass correlation coefficient (ICC) were calculated. The IWHAI was structured in five dimensions, integrating 43 health indicators, on a scale of 0-4, totalling 215 sub-indices with closed response coding. The instrument was validated with a Kappa coefficient (KAPPA) (k), with excellent agreement for all attributes, i.e., k = 0.88 for applicability, k = 0.80 for clarity and k = 0.82 for relevance. p > 0.05 results reveal moderate to strong positive correlations between some variables, i.e., pests, vectors and air quality/drinking water quality (rs = 0.69). A total of 14 components of the factor analysis, explaining 62.6% of the data variance, were extracted. α value is considered moderate to high, α = 0.61, the ICC value also being considered moderate to high, with ICC = 0.61. The IWHAI is considered validated, constituting a technological innovation for an interdisciplinary approach in the field of WH, enabling the prevention and integral promotion of health.

Prevalence trends of overweight, obesity, diabetes and hypertension among Brazilian women of reproductive age based on sociodemographic characteristics

The authors estimated the prevalence and trends of overweight, obesity, diabetes and hypertension among Brazilian women of reproductive age. A time series was constructed with Vigitel data from 2008 to 2015 and we analyzed trends of the prevalence of these conditions, considering sociodemographic characteristics. We observed an increasing trend in prevalence of overweight, obesity, and diabetes (for some sociodemographic characteristics), and stationary trends for hypertension. Our results highlight the need for early interventions in lifestyle of this population to reduce the NCDs risk factors burden and potentially contribute to improve maternal and neonatal outcomes and reduce the NCDs load.

Tendências temporais do consumo de frutas e hortaliças entre adultos nas capitais brasileiras e Distrito Federal, 2008-2016

Resumo: Analisar a tendência temporal do consumo de frutas e hortaliças entre adultos nas capitais brasileiras e no Distrito Federal no período entre 2008 e 2016. Trata-se de um estudo de série temporal, com dados do VIGITEL de 2008 a 2016 (n = 463.817). Analisou-se o percentual de consumo regular (≥ 5 dias/semana) e recomendado (≥ 5x/dia) de frutas e hortaliças, para cada um dos anos, para o conjunto completo da população e segundo sexo, faixa de idade, nível de escolaridade e localidade. A presença de tendência linear (de aumento ou diminuição) na variação dos indicadores foi analisada por meio da regressão Prais-Winsten. Verificou-se aumento significativo (p < 0,05) na prevalência de consumo regular (de 33 a 35,2%, aumento de 1,86%/ano) e de consumo recomendado de frutas e hortaliças (de 20 a 24,4%, aumento de 3,32%/ano). Tendência semelhante foi identificada para o percentual da população atendendo a recomendação de consumo na maior parte dos estratos populacionais, com maior magnitude de aumento entre: homens (4%/ano vs. 3,05%/ano para as mulheres), adultos jovens (3,97%/ano para aqueles com idades entre 18 e 24 anos vs. 2,3%/ano para os que têm de 55-64 anos), aqueles com menor escolaridade (2,97%/ano para aqueles com 0-8 anos de estudos vs. 2,76%/ano para os com 12 anos ou mais) e residentes em regiões menos desenvolvidas (5,02%/ano na Região Norte vs. 2,6%/ano na Região Sudeste). Observou-se aumento do consumo de frutas e hortaliças especialmente entre os grupos com menor nível de consumo no início do período estudado. No entanto, 3 a cada 4 indivíduos permanecem consumindo menos frutas e hortaliças do que o recomendado.

Prevalence of arterial hypertension in Brazilian adults and its associated factors and activity limitations: a cross-sectional study

BACKGROUND

Hypertension is a serious global public health problem that affects a large part of the Brazilian adult population and can cause limitations and losses of quality of life.

OBJECTIVE

The objective of this study was to analyze the association of hypertension and its correlated limitations, with sociodemographic and epidemiological factors.

DESIGN AND SETTING

Cross-sectional study analyzing information on 44,271 adults (30 years or older) from the Brazilian National Health Survey of 2013.

METHODS

The prevalence of hypertension and the degree of limitation of the patients' activities associated with hypertension, according to sociodemographic characteristics, anthropometric measurements and lifestyles, were calculated for both sexes. To analyze the strength of association, bivariate and multivariate Poisson regression were used.

RESULTS

Hypertension was the most prevalent risk factor among Brazilian adults aged 30 years or older (40.7%). It was strongly associated with the aging process (prevalence ratio, PR 3.51), obesity (PR 1.73), heart disease (PR 1.67) and stroke (PR 1.86). Furthermore, limitations associated with hypertension were more prevalent among those with comorbidities from noncommunicable diseases relating to hypertension complications (stroke PR 1.47; heart disease PR 1.69) and with incomplete elementary education (PR 1.19).

CONCLUSIONS

This study showed sociodemographic inequality in the prevalence of hypertension, especially in the population with some degree of limitation associated with hypertension. It showed that improvements in access to primary care services for controlling hypertension at its initial stages are essential in order to avoid comorbidities of greater severity and limitations and losses of quality of life, especially among socially disadvantaged people.

Body adiposity index in assessing the risk of type 2 diabetes mellitus development: the Baependi Heart Study

BACKGROUND

The association between diabetes and obesity is very well established. Faced with this, several anthropometric indices of adiposity are often involved in studies on diabetes. Our main goal in this paper is to evaluate the association between body adiposity index (BAI) and type 2 diabetes mellitus (T2DM) in a sample of the Brazilian population after 5-year follow-up.

METHODS

The data used come from the Baependi Heart Study cohort, which consists of two periods: cycle 1 (2005-2006) and cycle 2 (2010-2013). Individuals of both sexes (n = 1121) were selected by excluding participants with type 2 diabetes mellitus at baseline or those that were lost to follow-up.

RESULTS

The diabetic subjects showed higher systolic blood pressure, BAI, body mass index, waist circumference and fasting glucose levels. In addition, using mixed-effects logistic regression, we found that the elevation of a single unit of BAI represented an increase of 8.4% in the risk of a patient developing T2DM (OR = 1.084 [95% CI 1.045-1.124]).

CONCLUSIONS

Obesity is recognised as one of the most important risk factors for T2DM and BAI has proven to be a useful tool in estimating the risk of a patient developing T2DM in a Brazilian population.

Association Between Perceived Discrimination and Alcohol and Tobacco Consumption in ELSA-Brasil Cohort: Focusing on Gender Differences

BACKGROUND

Discrimination is detrimental to physical and mental health, particularly insofar as health-risk behaviors are concerned. Particular attention has been paid to excess alcohol consumption and smoking in view of the ready availability of these substances in Western societies.

OBJECTIVES

To determine whether an association exists between perceived discrimination and excess alcohol intake and smoking in women and men enrolled in the ELSA-Brasil cohort study.

METHODS

The sample included in the ELSA-Brasil cohort consisted of 15,105 civil servants. Data from waves 1 and 2 of the study were used. A multidimensional questionnaire was used to collect sociodemographic characteristics and evaluate perceived discrimination, alcohol consumption, and smoking.

RESULTS

An association was found between excess alcohol intake and perceived discrimination only in the men, with this association remaining significant in the youngest age group, in university-educated individuals, and in the group classified as middle-class. An association was found between smoking and lifetime perceived discrimination in women, particularly in those ≥60 years of age, brown-skinned women, those who had completed elementary school, and those classified as upper social class. This same association was found in the men, mainly those of 50-59 years of age, white-skinned males, those who had completed high school, those with a university education, and those classified as upper social class. Conclusions/Importance: Investing in public health policies aimed at combating the different forms of discrimination would appear essential. Not only does discrimination contribute to social injustice, but it also encourages health-risk behaviors such as excess alcohol intake and smoking.

Prevalence of arterial hypertension according to different diagnostic criteria, National Health Survey

OBJECTIVE

To determine the population prevalence of arterial hypertension in adults according to different diagnostic criteria.

METHODS

This is a cross-sectional study, analyzing information from the Brazilian National Health Survey in 2013, consisted of interviews, physical and laboratory measurements (n = 60,202). The prevalence of hypertension was defined according to three diagnostic criteria: self-reported; measured by instrument (blood pressure ≥ 140/90 mmHg); measured and/or using medication. Prevalence and 95% confidence interval (95%CI) were estimated by the three diagnostic criteria of hypertension.

RESULTS

The high blood pressure measurements were: 21.4% (95%CI 20.8 - 22.0) using the criterion self-reported; 22.8% (95%CI 22.1 - 23.4) by measured hypertension; and 32.3% (95%CI 31.7 - 33.0) by measured hypertension and/or reported use of medication. Women presented higher prevalence for the self-reported criterion (24.2%; 95%CI 23.4 - 24.9) and men, for the measured criterion (25.8%; 95%CI 24.8 - 26.8). Hypertension increases with age and is more frequent in urban areas. Using these three criteria, the hypertension was higher in the Southeast and South regions, in relation to the average of the country and the other regions. Using these three criteria, hypertension increased with age, was more frequent in urban areas and in the Southeast and South regions, in relation to the average of the country and the other regions.

CONCLUSION

These findings are important to support policies that aim to achieve the World Health Organization's goal of reducing hypertension by 25% over the next decade.

Changes in health and disease in Brazil and its States in the 30 years since the Unified Healthcare System (SUS) was created

The Unified Healthcare System (SUS) was created to ensure the population's right to universal, free and comprehensive healthcare. This study compares the health indicators measured in 1990 to those measured in 2015 in Brazil and its states. The goal is to contribute to understanding the role SUS played in changing the nation's health profile. Analyses use estimates in the Global Burden of Disease (GBD) study for Brazil and its states, and compares 1990 and 2015. The main results are increased life expectancy, as well as an increase in the population's longevity measured in health-adjusted life expectancy. These in turn are due to a sharp decline in mortality due to transmissible diseases, in maternal and infant morbi-mortality, and avoidable causes of death. NTCDs are the leading cause of death, followed by violence. Poor diet is the leading risk factor, followed by metabolic issues. Tobacco use decreased over the period, as did infant malnutrition. In the thirty years since the SUS was created, health indicators in this country have improved, and major progress has been made to reduce inequality across the country's regions.

Burden of ischemic heart disease mortality attributable to physical inactivity in Brazil

OBJECTIVE

To analyze if the burden of ischemic heart disease mortality trend attributed to physical inactivity in Brazil differs from the global estimates.

METHODS

Databases from the Global Burden of Disease Study for Brazil, Brazilian states, and global information were used. We estimated the summary exposure value for physical inactivity, the total number of deaths, and the age-standardized death rates for ischemic heart disease attributed to physical inactivity in the years 1990 and 2015, and the population-attributable fraction. Data were presented according to sex.

RESULTS

The Brazilian population was found to have a risk of exposure to physical inactivity varying between 70.4% for men and 75.7% for women in the year of 1990. This risk of exposure was similar in 2015. In men, the mortality rate from ischemic heart disease attributed to physical inactivity decreased in 2015 by approximately 24% around the world and 45% in Brazil. For women, this decrease was in 31% around the world and 45% in Brazil. The states of Southern and Southeastern Brazil presented lower mortality rates due to ischemic heart disease attributed to physical inactivity. If physical inactivity were eliminated in Brazil, mortality from ischemic heart disease would be reduced by 15.8% for men and 15.2% for women.

CONCLUSIONS

Over 25 years, the risk of exposure to physical inactivity in Brazil did not change and was high compared to global estimates. The decrease in ischemic heart disease mortality results from the improvement of health services in Brazil and the control of other risk factors. Approximately 15% of deaths from ischemic heart disease in Brazil could be avoided if people met the recommendations for physical activity.

Mortality and years of life lost due to breast cancer attributable to physical inactivity in the Brazilian female population (1990-2015)

The aims of this study were as follows: to estimate the mortality and years of life lost, assessed by disability-adjusted life years (DALYs), due to breast cancer attributable to physical inactivity in Brazilian women; to compare the estimates attributable to physical inactivity and to other modifiable risk factors; and to analyse the temporal evolution of these estimates within Brazilian states over 25 years (1990-2015), compared with global estimates. Databases from the Global Burden of Disease Study for Brazil, Brazilian states, and other parts of the world were used. Physical inactivity has contributed to a substantial number of deaths (1990: 875; 2015: 2,075) and DALYs (1990: 28,089; 2015: 60,585) due to breast cancer in Brazil. Physical inactivity was responsible for more deaths and DALYs (~12.0%) due to breast cancer than other modifiable risk factors (~5.0%). The Brazilian states with better socioeconomic indicators had higher age-standardized rates of mortality and morbidity due to breast cancer attributable to physical inactivity. From 1990 to 2015, mortality due to breast cancer attributable to physical inactivity increased in Brazil (0.77%; 95%U.I.: 0.27-1.47) and decreased (-2.84%; 95%U.I.: -4.35 - -0.10) around the world. These findings support the promotion of physical activity in the Brazilian female population to prevent and manage breast cancer.

Resumo O estudo analisa os avanços e desafios da implementação da Política Nacional de Promoção da Saúde (PNPS) quanto às suas agendas prioritárias e aponta aspectos críticos para sua sustentabilidade em tempos de crises. Estudo de revisão narrativa, abrangendo estudos publicados e documentação institucional. A PNPS foi aprovada em 2006 e revisada em 2014 e destaca a importância dos condicionantes e determinantes sociais da saúde no processo saúde-doença e tem como pressupostos a intersetorialidade e a criação de redes de corresponsabilidade que buscam a melhoria da qualidade de vida. Foram descritos avanços nas prioridades destacadas na PNPS, em programas e ações de enfrentamento ao uso do tabaco e seus derivados; alimentação adequada e saudável; práticas corporais e atividades físicas; promoção do desenvolvimento sustentável; o enfrentamento do uso abusivo de álcool e outras drogas; a promoção da mobilidade segura e sustentável; e a promoção da cultura da paz e de direitos humanos. Entretanto, os avanços da PNPS apresentados podem estar seriamente ameaçados frente à grave crise política, econômica e institucional que abateu o país, em especial os cortes orçamentários para os próximos 20 anos, com a Emenda Constitucional 95, desenhando um cenário futuro de muitas incertezas.

Mortality and years of life lost by colorectal cancer attributable to physical inactivity in Brazil (1990-2015): Findings from the Global Burden of Disease Study

INTRODUCTION

The aims of this study were to estimate all-cause and cause-specific mortality and years of life lost, investigated by disability-adjusted life-years (DALYs), due to colorectal cancer attributable to physical inactivity in Brazil and in the states; to analyze the temporal trend of these estimates over 25 years (1990-2015) compared with global estimates and according to the socioeconomic status of states of Brazil.

METHODS

Databases from the Global Burden of Disease Study (GBD) for Brazil, Brazilian states and global information were used. It was estimated the total number and the age-standardized rates of deaths and DALYs for colorectal cancer attributable to physical inactivity in the years 1990 and 2015. We used the Socioeconomic Development Index (SDI).

RESULTS

Physical inactivity was responsible for a substantial number of deaths (1990: 1,302; 2015: 119,351) and DALYs (1990: 31,121; 2015: 87,116) due to colorectal cancer in Brazil. From 1990 to 2015, the mortality and DALYs due to colorectal cancer attributable to physical inactivity increased in Brazil (0.6% and 0.6%, respectively) and decreased around the world (-0.8% and -1.1%, respectively). The Brazilian states with better socioeconomic indicators had higher rates of mortality and morbidity by colorectal cancer due to physical inactivity (p<0.01). Physical inactivity was responsible for deaths and DALYs due to colorectal cancer in Brazil.

CONCLUSIONS

Over 25 years, the Brazilian population showed more worrisome results than around the world. Actions to combat physical inactivity and greater cancer screening and treatment are urgent in the Brazilian states.

Fatores associados ao uso de narguilé e outros produtos do tabaco entre escolares, Brasil, 2015

RESUMO: Objetivo: Identificar a frequência e os fatores associados ao uso de narguilé e outros produtos do tabaco entre os escolares brasileiros. Métodos: Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar. A amostra foi composta por alunos do 9º ano do Ensino Fundamental. Foi realizada análise descritiva do uso de produtos do tabaco em 2012 e 2015. Para explorar a relação de fatores como características sociodemográficas, familiares, saúde mental e hábitos de vida com o uso de outros produtos do tabaco, foram calculados odds ratio ajustados. Resultados: O uso de outros produtos do tabaco aumentou de 4,8% (IC95% 4,6 - 5,0), em 2012, para 6,1% (IC95% 5,7 - 6,4), em 2015, com maior proporção em meninos. O narguilé foi o produto mais usado em 2015 (71,6%; IC95% 68,8 - 74,2), sendo mais frequente em meninas. Foram positivamente associados ao uso de outros produtos do tabaco: escola privada, morar com pai/mãe, trabalhar, não ter amigos, sofrer violência familiar, faltar às aulas, fazer uso de cigarros e álcool, ter experimentado drogas, já ter tido relação sexual, ter pais ou responsáveis fumantes e presenciar pessoas fumando. Os fatores de proteção foram: sexo feminino, incremento da idade, cor da pele parda ou indígena, fazer refeições com responsável, ter supervisão familiar e praticar atividade física. Conclusão: Conclui-se que o uso de outros produtos do tabaco foi elevado, com aumento nos últimos anos, destacando-se o narguilé. Torna-se importante a conscientização dos riscos e a vigilância do uso desses produtos, bem como o avanço das políticas públicas de controle do tabagismo no país.
