Noncommunicable diseases and injuries represent the greatest cause of morbidity and mortality in Brazil and worldwide, besides resulting in premature deaths, disabilities, loss of quality of life, and important economic impacts¹1 Malta DC, Silva MM. A. As doenças e agravos não transmissíveis, o desafio contemporâneo na Saúde Pública. Ciênc Saúde Coletiva 2018; 23(5): 1350. https://doi.org/10.1590/1413-81232018235.31552017
https://doi.org/10.1590/1413-81232018235... ,²2 World Health Organization. Noncommunicable Diseases Progress Monitor 2020. Geneva: WHO; 2020a.. Noncommunicable diseases and injuries comprise two major groups of events: chronic noncommunicable diseases (NCDs), mainly characterized by cardiovascular diseases, chronic respiratory diseases, neoplasms, and diabetes mellitus; and external causes such as accidents and violence¹1 Malta DC, Silva MM. A. As doenças e agravos não transmissíveis, o desafio contemporâneo na Saúde Pública. Ciênc Saúde Coletiva 2018; 23(5): 1350. https://doi.org/10.1590/1413-81232018235.31552017

NCDs are estimated to cause 41 million deaths worldwide per year, which is equivalent to more than 70% of deaths, of which 15 million are premature (<70 years)²2 World Health Organization. Noncommunicable Diseases Progress Monitor 2020. Geneva: WHO; 2020a.. In Brazil, in 2019, the overall mortality due to NCDs corresponded to about 76% and premature deaths totaled 66.1%³3 Malta DC, Duncan BB, Schmidt MI, Teixeira R, Ribeiro ALP, Felisbino-Mendes MS, et al. Trends in mortality due to non-communicable diseases in the Brazilian adult population: national and subnational estimates and projections for 2030. Popul Health Metrics 2020; 18(Suppl 1): 16. https://doi.org/10.1186/s12963-020-00216-1
https://doi.org/10.1186/s12963-020-00216... . NCDs result in devastating consequences for individuals, families, and communities in addition to overloading healthcare systems⁴4 World Health Organization. Global action plan for the prevention and control of noncommunicable diseases 2013-2020 [Internet]. Genebra: WHO; 2013 [cited on Dec. 14, 2022]. Available at: https://www.who.int/nmh/events/ncd_action_plan/en/
https://www.who.int/nmh/events/ncd_actio... . Violence and accidents are responsible for over 4.8 million deaths worldwide; in Brazil, there are about 150 thousand deaths each year, including lives lost prematurely in addition to disabilities, loss of quality of life, and important impacts on the Brazilian Unified Health System (SUS) and the economy⁵5 Malta DC, Souza ER. A busca de sociedades pacíficas e inclusivas até 2030. Rev Bras Epidemiol 2020; 23(Suppl. 01): e200001.SUPL.1. https://doi.org/10.1590/1980-549720200001.supl.1

This supplement from the Brazilian Journal of Epidemiology (Revista Brasileira de Epidemiologia – RBE) addresses the challenge of health surveys and information systems in the monitoring of noncommunicable diseases and injuries. National surveys are components of extreme relevance in a national health system and essential to know the health profile, the distribution of risk factors, their trends, health inequalities, and social determinants. The information periodically collected enables the monitoring of health actions and programs in different population strata in addition to contributing to subsidize public policies⁶6 Malta DC, Szwarcwald CL, Silva Junior JB. Primeiros resultados da análise do laboratório da Pesquisa Nacional de Saúde. Rev Bras Epidemiol [Internet] 2019; 22(supl. 2): E190001 cited on Nov. 17, 2020]. Available at:http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415790X2019000300100&lng=en&nrm=iso
http://www.scielo.br/scielo.php?script=s... .

The supplement highlights the importance of the National Survey of Health (Pesquisa Nacional de Saúde – PNS), generating key information to monitor the health of Brazilians. One of the articles analyzes data from the PNS laboratory, collected in the years 2014/2015 and the reference intervals referring to the blood cell count of Brazilian adults, with and without sickle cell trait⁷7 Sá ACMGN, Silva AG, Gomes CS, Nogueira de Sá AT, Malta DC. Diferenças entre intervalos de referência de hemograma de adultos brasileiros com e sem traço falciforme segundo os exames laboratoriais da Pesquisa Nacional de Saúde. Rev Bras Epidemiol 2023; (Suppl 1): e230003.supl.1. https://doi.org/10.1590/1980-549720230003.supl.1.1
https://doi.org/10.1590/1980-54972023000... ,⁸8 Sá ACMGN, Bacal NS, Gomes CS, Silva TMR, Gonçalves PF, Malta DC. Intervalos de referência de hemograma da população adulta brasileira: Pesquisa Nacional de Saúde. Rev Bras Epidemiol 2023; (Suppl 1): e230004.supl.1. https://doi.org/10.1590/1980-549720230004.supl.1.1
https://doi.org/10.1590/1980-54972023000... . The database of the PNS becomes innovative by incorporating the collection of biological material (blood and urine) in a subsample, making it fundamental to evaluate NCDs, the occurrence of diseases, and the distribution of biological markers in the population. The inclusion of the “PNS laboratory” component in the next edition of the research is of great relevance⁶6 Malta DC, Szwarcwald CL, Silva Junior JB. Primeiros resultados da análise do laboratório da Pesquisa Nacional de Saúde. Rev Bras Epidemiol [Internet] 2019; 22(supl. 2): E190001 cited on Nov. 17, 2020].

In another article concerning PNS, work-related and commuting accidents among employed Brazilians in 2013 and 2019 were analyzed⁹9 Malta DC, Bernal RTIB, Vasconcelos NM, Ribeiro A, Vasconcelos LLM, Machado E. Acidentes no deslocamento e no trabalho entre brasileiros ocupados, Pesquisa Nacional de Saúde 2013 e 2019. Rev Bras Epidemiol 2023; (Suppl 1): e230006.supl.1. https://doi.org/10.1590/1980-549720230006.supl.1.1
https://doi.org/10.1590/1980-54972023000... . The PNS enables to measure these occurrences, which are underreported, due to a large part of the working population being inserted in informal work, without basic rights. PNS shows important inequalities in the occurrence of work-related accidents, which predominate among men, young people, Black individuals, those with lower levels of education, and rural workers⁹9 Malta DC, Bernal RTIB, Vasconcelos NM, Ribeiro A, Vasconcelos LLM, Machado E. Acidentes no deslocamento e no trabalho entre brasileiros ocupados, Pesquisa Nacional de Saúde 2013 e 2019. Rev Bras Epidemiol 2023; (Suppl 1): e230006.supl.1. https://doi.org/10.1590/1980-549720230006.supl.1.1
https://doi.org/10.1590/1980-54972023000... .

For the first time, in the PNS 2019, population data on violence against gay, lesbian, and bisexual (LGB+) people were analyzed in Brazil. The study points out that the reported prevalence values are about two to three times higher among LGB+, showing the vulnerability of the LGB+ population in the country and the need for social protection policies¹⁰10 Vasconcelos NM, Alves FTA, Andrade GN, Pinto IV, Soares Filho AM, Pereira CA, et al. Violência contra pessoas LGB+ no Brasil: análise da Pesquisa Nacional de Saúde, 2019. Rev Bras Epidemiol 2023; (Suppl 1): e230005.supl.1. https://doi.org/10.1590/1980-549720230005.supl.1.1
https://doi.org/10.1590/1980-54972023000... .

Articles analyze the database of the National Survey of School Health (Pesquisa Nacional de Saúde do Escolar – PeNSE), conducted by the Brazilian Institute of Geography and Statistics (IBGE), in partnership with the Brazilian Ministry of Health, with the aim of estimating the prevalence of risk factors and health protection of schoolchildren aged 13 and 17 years throughout the country as well as tracking trends over time. Reis et al.¹¹11 Reis GB, Sousa MA, Andrade GN, Malta DC, Machado IE, Felisbino-Mendes MS. Supervisão dos pais e comportamento sexual entre adolescentes brasileiros. Rev Bras Epidemiol 2023; (Suppl 1): e230013.supl.1. https://doi.org/1010.1590/1980-549720230013.supl.1.1
https://doi.org/1010.1590/1980-549720230... highlight the importance of parental supervision regarding risky sexual behavior among Brazilian adolescents, pointing out that young people with higher number of parental supervision indicators simultaneously had higher prevalence of condom use¹¹11 Reis GB, Sousa MA, Andrade GN, Malta DC, Machado IE, Felisbino-Mendes MS. Supervisão dos pais e comportamento sexual entre adolescentes brasileiros. Rev Bras Epidemiol 2023; (Suppl 1): e230013.supl.1. https://doi.org/1010.1590/1980-549720230013.supl.1.1
https://doi.org/1010.1590/1980-549720230... . Another study analyzes child labor, which is part of contexts of vulnerability and socioeconomic inequalities in which children and adolescents are inserted, perpetuating cycles of vulnerabilities. The authors highlight that child labor is associated with higher prevalence of risk factors, which may result in NCDs throughout life¹²12 Ferreira AC, Silva AG, Gomes CS, Malta DC. Associação do trabalho infantil com fatores de risco e proteção para Doenças Crônicas não Transmissíveis em escolares brasileiros: Pesquisa Nacional de Saúde do Escolar 2015. Rev Bras Epidemiol 2023; (Suppl 1): e230012.supl.1. https://doi.org/10.1590/1980-549720230012.supl.1.1
https://doi.org/10.1590/1980-54972023001... . Another article analyzes the demand, as well as the use, by Brazilian adolescents for health services, according to PeNSE, showing the importance of Primary Health Care in meeting this demand¹³13 Silva AG, Gomes CS, Malta DC. Procura e utilização dos serviços de saúde por adolescentes brasileiros, segundo a Pesquisa Nacional de Saúde do Escolar de 2019. Rev Bras Epidemiol 2023; (Suppl 1): e230008.supl.1. https://doi.org/10.1590/1980-549720230008.supl.1.1
https://doi.org/10.1590/1980-54972023000... .

Two articles analyze data from the Surveillance System of Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel), which annually monitors, since 2006, via telephone interviews, the risk and protection factors of NCDs in adults (age ≥18 years) living in the capitals of the 26 Brazilian states and the Federal District. One of the articles analyzes the trend of behaviors among older adults¹⁴14 Silva AG, Andrade FM, Ribeiro EG, Malta DC. Tendências temporais de morbidades, fatores de risco e de proteção para doenças crônicas não transmissíveis em pessoas idosas residentes nas capitais brasileiras. Rev Bras Epidemiol 2023; (Suppl 1): e230009.supl.1. https://doi.org/10.1590/1980-549720230009.supl.1.1
https://doi.org/10.1590/1980-54972023000... ; the other analyzes the trend of indicators of physical activity in adults, highlighting the worsening of indicators in the COVID-19 pandemic years, with reduced physical activity in spare time and increased sedentary behavior¹⁵15 Faria TMTR, Silva AG, Claro RM, Malta DC. Time trends and COVID-19 post pandemic changes in physical activity and sedentary behavior prevalence among Brazilian adults between 2006 and 2021. Rev Bras Epidemiol 2023; (Suppl 1): e230011.supl.1. https://doi.org/10.1590/1980-549720230011.supl.1.1
https://doi.org/10.1590/1980-54972023001... .

Behaviors also changed among adolescents, according to the ConVid Adolescentes – Pesquisa de Comportamentos (Research on Adolescents’ Behavior), which analyzes the reduction of alcohol consumption among adolescents during the COVID-19 pandemic. This consumption is associated with the presence of friends, “their peers,” which was greatly reduced during social distancing in the period¹⁶16 Malta DC, Gomes CS, Vasconcelos NM, Barros MBA, Lima MG, Souza Júnior PRB, et al. O consumo de bebidas alcóolicas entre adolescentes durante a pandemia do Covid 19, Convid Adolescentes - Pesquisa de Comportamentos. Rev Bras Epidemiol 2023; (Suppl 1): e230007.supl.1. https://doi.org/10.1590/1980-549720230007.supl.1.1
https://doi.org/10.1590/1980-54972023000... .

In this supplement of the RBE, one of the articles discusses the mortality trends of NCDs, showing the decline in rates over the last decade and the importance of correcting mortality data from the Brazilian Mortality Information System (Sistema de Informação sobre Mortalidade – SIM), especially in the redistribution of garbage codes (GC), aiming at the adequacy of estimates¹⁷17 Malta DC, Teixeira RA, Cardoso LSM, Souza JB, Bernal RTI, Pinheiro PC, et al. Mortalidade prematura por doenças crônicas não transmissíveis em capitais brasileiras: redistribuição de causas garbage e evolução por estratos de privação social. Rev Bras Epidemiol 2023; (Suppl 1): e230002.supl.1. https://doi.org/10.1590/1980-549720230002.supl.1.1
https://doi.org/10.1590/1980-54972023000... . Another article also uses corrections by GC and analyzes mortality patterns due to external causes in municipalities in the mining region of Vale do Paraopeba, before the rupture of the Brumadinho dam, in the state of Minas Gerais, being a baseline in the region, prior to the environmental disaster¹⁸18 Malta DC, Reis GM, Veloso GA, Cardoso LSM, Hartz ZMA, Cunningham M, et al. Padrões de mortalidade em municípios de uma região mineradora antes do rompimento da barragem de Brumadinho, Minas Gerais, Brasil. Rev Bras Epidemiol 2023; (Suppl 1). https://doi.org/10.1590/1980-549720230010.supl.1.1
https://doi.org/10.1590/1980-54972023001... .

The information produced in this supplement demonstrates the health conditions of Brazilians and promotes scientific communication, by the publication of articles that present original results of analyses related to the Noncommunicable Diseases and Injuries and Health Surveys topic. The information periodically collected by these studies allows monitoring health actions and programs in different population strata and contributes to subsidize public policies. We wish you all a good reading of these articles.
