Cyberbullying among Brazilian schoolchildren: data from the National Student Health Survey, 2019. / Cyberbullying entre escolares brasileiros: dados da Pesquisa Nacional de Saúde do Escolar, 2019.

This cross-sectional study assessed data from Brazil's 2019 National Student Health Survey to investigate associations between cyberbullying and sociodemographic, family, mental health, and behavioural factors among Brazilian schoolchildren. Multivariate analysis by Poisson regression found 13.2% prevalence of cyberbullying, which was higher among adolescents who felt nobody cared about them (PR=1.47; 1.36-1.59); felt sad (PR=1.5; 1.4-1.7); reported that life was not worth living (PR=1.71; 1.59-1.84); had no friends (PR=1.68; 1.50-1.87); suffered parental aggression (PR=1.54; 1.45-1.65); missed classes without permission (PR=1.13; 1.06-1.20); used tobacco (PR=1.19; 1.10-1.30); alcoholic beverages (PR=1.16; 1.08-1.25); or illicit drugs (PR=1.14; 1.04-1.25); or had sexual intercourse (PR=1.23; 1.14-1.33). Prevalence was lower among boys (PR=0.85; 0.80-0.91); those 16-17 years old (PR=0.88; 0.82-0.95); and who reported having parental supervision in their free time (PR=0.78; 0.73-0.83). Cyberbullying has a high prevalence, highlighting the importance of monitoring this practice and establishing prevention measures in schools.

O estudo analisou a associação entre Cyberbullying e fatores sociodemográficos, familiares, de saúde mental e comportamentais em escolares (13 a 17 anos) brasileiros. Trata-se de um estudo transversal com dados da PeNSE 2019. Realizou-se análise multivariada com regressão de Poisson. A prevalência de Cyberbullying foi de 13,2% e foi maior entre os adolescentes que sentiam que ninguém se preocupava com eles (RP=1,47; 1,36-1,59); se sentiam tristes (RP=1,5; 1,4-1,7); referiram que a vida não vale a pena (RP=1,71; 1,59-1,84); não tinham amigos (RP=1,68; 1,50-1,87); sofriam agressão dos pais (RP=1,54; 1,45-1,65); faltavam às aulas sem autorização (RP=1,13; 1,06-1,20); usavam tabaco (RP=1,19; 1,10-1,30); bebidas alcóolicas (RP=1,16; 1,08-1,25); drogas ilícitas (RP=1,14; 1,04-1,25); e tiveram relação sexual (RP=1,23; 1,14-1,33). Tiveram menor prevalência os adolescentes do sexo masculino (RP=0,85; 0,80-0,91), os mais velhos (16-17 anos) (RP=0,88; 0,82-0,95) e que reportaram ter supervisão dos pais no tempo livre (RP=0,78; 0,73-0,83). O Cyberbullying tem elevada prevalência e destaca-se a importância de monitorar a prática, estabelecendo ações de prevenção nas escolas.

Changes in tobacco use and associated factors among Brazilian adolescents: National Student Health Survey. / Mudanças no uso do tabaco entre adolescentes brasileiros e fatores associados: Pesquisa Nacional de Saúde do Escolar.

This cross-sectional study used data from Brazil's National Student Health Survey (PeNSE), from 2015 and 2019, to compare consumption of tobacco products among adolescent students in Brazil and identify associated factors. The study variables were current cigarette smoking, use of other tobacco products and use of any tobacco product. Pearson's Chi-square test was used to ascertain associations between the variables; bivariate and multivariate analyses were performed using logistic regression. Cigarette smoking remained stable between 2015 (6.6%) and 2019 (6.8%), but use of any tobacco product increased (from 10.6% in 2015 to 14.8% in 2019), involving particularly hookahs (7.8%) and e-cigarettes (2.8%). Cigarette smoking was greater among adolescents aged 16 and 17, whose skin colour was black or brown, who missed classes without permission, who reported having no friends, displayed other risk factors, such as drinking alcoholic beverages, or who were passive smokers. The prevalence of smoking has increased over the years and is associated with sociodemographic aspects and other health risk behaviour, highlighting the need for lifelong health promotion actions.

O estudo objetiva comparar o consumo de diferentes produtos do tabaco entre os escolares adolescentes no Brasil em 2015 e 2019 e identificar os fatores associados ao seu uso. Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015 e 2019. Variáveis: uso atual de cigarro, uso de outros produtos do tabaco e uso de qualquer produto do tabaco. Foi usado o teste do Qui-quadrado de Pearson para verificar associação entre as variáveis, realizada análise bivariada e a multivariada por meio da regressão logística. O uso de cigarros se manteve estável entre 2015 (6,6%) e 2019 (6,8%). Mas houve aumento do uso de qualquer produto do tabaco (de 10,6% em 2015 para 14,8% em 2019), sendo o narguilé o mais frequente (7,8%) seguido do cigarro eletrônico (2,8%). O uso de cigarro foi mais elevado entre os adolescentes de 16 e 17 anos, com cor da pele preta e parda, que faltaram as aulas sem autorização, entre aqueles que relataram não ter amigos, que apresentavam outros fatores de risco como consumir bebidas alcoólicas e que eram fumantes passivos. A prevalência de tabagismo aumentou ao longo dos anos e foi associada com aspectos sociodemográficos e a outros comportamentos de risco à saúde, o que alerta para a necessidade de ações de promoção da saúde ao longo do ciclo de vida.

Chronic back pain among Brazilian adults: data from the 2019 National Health Survey. / Dor crônica na coluna entre adultos brasileiros: dados da Pesquisa Nacional de Saúde 2019.

OBJECTIVE: To estimate the prevalence of chronic back pain (CBP) and its associated factors. METHODS: This cross-sectional study analyzed the 2019 National Health Survey, with 88,531 adults, using logistic regression to identify associated factors. RESULTS: CBP was reported by 21.6% of adults and was more likely to occur among women (odds ratio - OR=1.27; 95% confidence interval - 95%CI 1.19-1.35), increased with age: 25-34 years (OR=1.30; 95%CI 1.11-1.51), 35-44 (OR=1.78; 95%CI 1.54-2.07), 45-54 years (OR=2.23; 95%CI 1.91-2.59), 55-64 years (OR=2.47; 95%CI 2.12-2.88), and 65 years or older (OR=2.17; 95%CI 1.85-2.54); among smokers (OR=1.24; 95%CI 1.13-1.35); ex-smokers (OR=1.30; 95%CI 1.21-1.39); those who mentioned heavy housework (OR=1.41; 95%CI 1.31-1.53); obesity (OR=1.12; 95%CI 1.03-1.21); hypertension (OR=1.21; 95%CI 1.11-1.32); high cholesterol (OR=1.53; 95%CI 1.42-1.65); with self-rated health - with a very good reference - in the gradients: good (OR=1.38; 95%CI 1.23-1.55), regular (OR=2.64; 95%CI 2.34-2.98), poor (OR=4.24; 95%CI 3.64-4.94), and very poor (OR=5.24; 95%CI 4.13-6.65); its likelihood was lower in adults with complete elementary school/incomplete high school (OR=0.82; 95%CI 0.75-0.90) and complete high school/incomplete higher education (OR=0.87; 95%CI 0.81-0.95). CONCLUSION: Back pain has a high prevalence and shows associations with demographic and socioeconomic factors, lifestyle, chronic diseases, and self-rated health.

MÉTODOS: Estudo transversal analisando a Pesquisa Nacional de Saúde 2019, com 88.531 adultos, usando regressão logística para identificar fatores associados. RESULTADOS: A DCC foi apontada por 21,6% dos adultos, mostrou maior chance em mulheres (odds ratio ­ OR=1,27; intervalo de confiança de 95% ­ IC95% 1,19­1,35), aumentou com a idade de 25­34 anos (OR=1,30; IC95% 1,11­1,51), 35­44 (OR=1,78; IC95% 1,54­2,07), 45­54 anos (OR=2,23; IC95% 1,91­2,59), 55­64 anos (OR=2,47; IC95% 2,12­2,88) e 65 anos ou mais (OR=2,17; IC95% 1,85­2,54); fumantes (OR=1,24; IC95% 1,13­1,35); ex-fumantes (OR=1,30; IC95% 1,21­1,39); que citaram atividade física doméstica pesada (OR=1,41; IC95% 1,31­1,53); obesidade (OR=1,12; IC95% 1,03­1,21); hipertensos (OR=1,21; IC95% 1,11­1,32); colesterol aumentado (OR=1,53; IC95% 1,42­1,65); autoavaliação, cuja referência era muito boa, mostrou gradiente boa (OR=1,38; IC95% 1,23­1,55); regular (OR=2,64; IC95% 2,34­2,98), ruim (OR=4,24; IC95% 3,64­4,94), e muito ruim (OR=5,24; IC95% 4,13­6,65); e menor chance em adultos com ensino fundamental completo/ensino médio incompleto (OR=0,82; IC95% 0,75­0,90) e médio completo/superior incompleto (OR=0,87; IC95% 0,81­0,95). CONCLUSÃO: A dor na coluna tem elevada prevalência e mostra associação com fatores demográficos, socioeconômicos, estilo de vida, doenças crônicas e autoavaliação de saúde.

Inequalities in health care and access to health services among adults with self-reported arterial hypertension: Brazilian National Health Survey.

This study compared indicators of care and access to health services by adults who self-reported hypertension in 2013 and 2019, analyzing those indicators according to gender, age group, schooling level, and race/color. This is an analytic study with data from the Brazilian National Health Survey (PNS), conducted in 2013 and 2019 in Brazil. The indicators to care and access to health services by individuals with arterial hypertension in both surveys were compared. For 2019, those indicators were analyzed according to sociodemographic characteristics. This study estimated the proportions, prevalence ratio (PR), and their respective 95% confidence intervals (95%CI). In total, 60,202 individuals were evaluated in 2013 and 88,531 in 2019, of these 24.4% reported arterial hypertension in 2013 and 23.9% in 2019. Women received more medical care for hypertension within the last year (PR = 1.07; 95%CI: 1.04; 1.11), had the last physician appointment at an basic health unit (PR = 1.11; 95%CI: 1.05; 1.17) than men. About race/color, black people had more hospitalization for hypertension or some complication (PR = 1.2; 95%CI: 1.05; 1.38) and intense or very intense degree of limitation in performing daily activities (PR = 1.37; 95%CI: 1.06; 1.76). In 2019, inequalities were evidenced and worse indicators were observed for males, black, with low education and young age. Therefore, investments in the Brazilian Unified National Health System, as well as public policies and strategic actions are essential to reduce inequalities, promote health care.

Monitoring the goals of the plans for coping with Chronic Non-Communicable Diseases: results of the National Health Survey, Brazil, 2013 and 2019. / Monitoramento das metas dos planos de enfrentamento das Doenças Crônicas Não Transmissíveis: resultados da Pesquisa Nacional de Saúde, 2013 e 2019.

OBJECTIVE: To monitor the achievement of the action plans for the prevention and control of Non-Communicable Diseases agreed-upon targets. METHODS: Cross-sectional study, with data from the 2013 and 2019 National Health Survey. The following targets, up to 2025, were evaluated: physical inactivity, alcohol consumption, salt/sodium, tobacco use, high blood pressure, diabetes, overweight, obesity, cervical cytology testing, and drug therapy and counseling. To check whether the targets were achieved, the prevalence ratio was calculated (PR). RESULTS: 60,202 individuals were assessed in 2013, and 88,531 in 2019. The targets for physical inactivity (PR = 0.88; 95%CI 0.86;0.90) and cervical cytology coverage (79.4%; 95%CI 78.3;80.3) were achieved. Tobacco use was reduced, albeit below the target. The prevalence of hypertension, diabetes, overweight, obesity and alcohol consumption increased, and the targets will not be attained. CONCLUSION: Two indicators reached the agreed targets, however it is necessary to advance in actions and policies to meet the others.

Self-reported arterial hypertension, use of health services and guidelines for care in Brazilian population: National Health Survey, 2019. / Hipertensão arterial autorreferida, uso de serviços de saúde e orientações para o cuidado na população brasileira: Pesquisa Nacional de Saúde, 2019.

OBJECTIVE: To describe the prevalence of arterial hypertension according to sociodemographic characteristics in Brazil and to analyze the indicators related to access to health services and guidelines for controlling the disease in the country. METHODS: Cross-sectional descriptive study using the National Health Survey (PNS) conducted in 2019. The prevalence of hypertension was estimated with a 95% confidence interval, in addition to the proportions of hypertension indicators. RESULTS: There were 88,531 respondents, of which 23.9% self-reported hypertension, more prevalent among females (26.4%) and the elderly (55.0%). Among those who self-reported hypertension, 57.8% reported medical attention in the last six months; most received guidance on self-care; 66.1% were seen in public health services; and 45.8%, in primary health care units. CONCLUSION: The prevalence of hypertension in the Brazilian population was high, with most people who self-reported the condition being seen in services of the Brazilian National Health System (SUS), where they received guidance on health promotion.

Indicators of the line of care for people with diabetes in Brazil: National Health Survey 2013 and 2019. / Indicadores da linha de cuidado de pessoas com diabetes no Brasil: Pesquisa Nacional de Saúde 2013 e 2019.

OBJECTIVE: To compare health care indicators for adults with medical diagnosis of diabetes mellitus (DM) in Brazil, in 2013 and 2019, and analyze the indicators for 2019 according to sociodemographic characteristics. METHODS: Cross-sectional study using data from the 2013 and 2019 National Health Survey. Care indicators were evaluated in people with medical diagnosis of DM. RESULTS: DM prevalence increased from 6.2% (2013) to 7.7% (2019). Between 2013 and 2019, there was an increase in the use of medications (from 80.2% to 88.8%) and of medical care (from 73.2% to 79.1%), a reduction in the use of Popular Pharmacy Program medications (from 57.4% to 51.5%) and in follow-up with the same physician (from 65.2% to 59.4%). In 2019, poorer indicators were observed for individuals who were male, younger, Black and Brown, and with lower education and income. CONCLUSION: Most indicators remained similar in the last five years, with differences according to sociodemographic characteristics in 2019.

Analysis of demand and access to services in the last two weeks previous to the National Health Survey 2013 and 2019.

OBJECTIVE: Compare the demand and use of health services between 2013 and 2019, and analyze the associated sociodemographic and health variables in 2019. METHODS: Cross-sectional study with data from the National Health Survey (PNS) 2013 and 2019. The prevalence and 95% confidence intervals (95% CI) for the demand and use of health services were estimated. In 2019, the differences in the indicators were analyzed according to sociodemographic variables and the crude and adjusted by sex and age prevalence ratios (RP) were estimated. RESULTS: There was an increase of 22% in the demand for health care in the last two weeks, going from 15.3% (95%CI 15.0-15.7) in 2013 to 18.6% (95%CI 18.3-19.0) in 2019. There was a reduction in use in the last two weeks, from 97% (95%CI 96.6-97.4) in 2013 to 86.1% (95%CI 85.4-86.8) in 2019, which was observed for most Federation Units. In 2019, the demand for care was greater among women, the elderly, those with high schooling, individuals with health insurance and poor self-rated health. They obtained greater access to health services in the fifteen days prior to the survey: men, children or adolescents up to 17 years of age, people with health insurance and poor health self-assessment. CONCLUSION: The demand for health services has grown and reduced access in the last 15 days between 2013 and 2019. These differences may have been exacerbated by the austerity measures implemented in the country.

Tobacco use, cessation, secondhand smoke and exposure to media about tobacco in Brazil: results of the National Health Survey 2013 and 2019.

OBJECTIVE: To compare indicators of tobacco use, secondhand smoke, cessation and exposure to pro- and anti-tobacco media in 2013 and 2019, and to describe these indicators according to sociodemographic variables in 2019. METHODS: Cross-sectional study with data from the National Health Survey. The indicators of use, secondhand smoke, cessation and exposure to tobacco-related media were evaluated. Prevalence and confidence intervals (95%CI) were estimated for the total population in 2013 and 2019 and according to sociodemographic variables for 2019. Poisson regression with robust variance was used to assess differences in prevalence. RESULTS: There was an improvement in most of the indicators studied: an increase in ex-smokers, a reduction in secondhand smoke and attempts to quit smoking. All pro- and anti-tobacco media exposure indicators declined. When considering the prevalence according to sociodemographic characteristics in 2019, 43.8% (95%CI 41.6-46.0) of men tried to quit smoking, and 50.8% (95%CI 48.5-53.2) of women. Secondhand smoke at home was higher among women (10.2%; 95%CI 9.7-10.8). Among those who thought about quitting smoking because of warnings, the proportion was higher among women (48.0%; 95%CI 45.3-50.6). Tobacco use was higher among men (43.8%; 95%CI 41.6-46.0), in the population aged 40 to 59 years (14.9%; 95%CI 14.2-15.6), with a lower level of education (17.6%; 95%CI 16.8-18.4). CONCLUSION: The study showed improvement in tobacco-related indicators between the years studied. It is noteworthy that this advance was smaller in relation to the other periods previously analyzed, and therefore, greater investments in public policies to combat and control smoking in Brazil are necessary.

Changes in the pattern of health services use in Brazil between 2013 and 2019. / Mudanças no padrão de utilização de serviços de saúde no Brasil entre 2013 e 2019.

This study aimed to investigate changes in the health service use pattern based on information from the 2013 and 2019 National Health Surveys (PNS). The two outcomes, "Seeking health-related care in the past two weeks" and "Medical visit in the last twelve months", were analyzed according to socioeconomic, geographic and health conditions characteristics. Multivariate Poisson regression models were used to investigate the factors associated with seeking care due to a health problem or prevention. The prevalence of chronic diseases increased from 15.0% to 22.5% between 2013 and 2019. The proportion of seeking care increased from 15.3 to 18.6%, and medical visits from 71.2% to 76.2%, ranging from 61.4 to 75.8% and 68.0 to 80.6% between the North and Southeast regions. There was no significant association of seeking care due to a health problem with per capita income, after controlling for the other covariates. We conclude by saying that, despite the expanded coverage of health service use, the persistent regional inequalities indicate unmet health needs among residents of the less developed regions. Health care models focused on prevention and health promotion are required.

Este estudo teve o objetivo de comparar os padrões de utilização de serviços de saúde, a partir das informações das edições da Pesquisa Nacional de Saúde (PNS), 2013 e 2019. Os dois desfechos "Procura de atendimento relacionado à saúde nas últimas duas semanas" e "Consulta médica nos últimos doze meses" foram analisados segundo fatores socioeconômicos, geográficos, e condições de saúde. Foram usados modelos multivariados de regressão de Poisson para investigar os fatores associados à procura de atendimento de acordo com o motivo (problema de saúde ou prevenção). Entre 2013 e 2019, a prevalência de doenças crônicas aumentou de 15,0% a 22,5%. A proporção de busca de atendimento cresceu de 15,3 a 18,6%, e de uso de médico, de 71,2% a 76,2%, com amplitudes de variação de 61,4-75,8% e 68,0-80,6% entre as regiões Norte e Sudeste. Para atendimento por problema de saúde, não houve associação significativa com rendimento per capita, após o controle das demais covariáveis. Conclui-se que apesar da expansão da cobertura de utilização de serviços de saúde, as persistentes desigualdades regionais indicam necessidades de saúde não atendidas entre os residentes das regiões menos desenvolvidas. Modelos de atenção focados na prevenção e promoção da saúde são necessários.

Associação entre avaliação elevada da Atenção Primária à Saúde, estado de saúde e uso dos serviços de saúde no Brasil / Association between high assessment of Primary Health Care and health state and use of health services in Brazil

RESUMO O estudo descreveu as características dos indivíduos que utilizam os serviços da Atenção Primária à Saúde (APS) e avaliou a associação entre a avaliação elevada dos atributos da APS, sob a ótica dos usuários, com o estado de saúde e o uso dos serviços de saúde no Brasil. Trata-se de um estudo transversal que analisou dados da Pesquisa Nacional de Saúde 2019, com amostra de 9.562 adultos que responderam ao Primary Care Assessment Tool (PCATool). Foi testada a associação entre avaliação elevada da APS (escore geral ≥ 6,6) e estado de saúde e uso dos serviços. Verificou-se que os usuários adultos que mais utilizam a APS pública têm entre 40 e 59 anos, são mulheres, de baixa escolaridade e pardos. Os que melhor avaliaram a APS foram indivíduos que utilizaram o mesmo serviço, procuraram serviços nas últimas duas semanas e se internaram. Maior uso dos serviços aponta para melhor avaliação da APS.

ABSTRACT The present study described the characteristics of individuals who use Primary Health Care (PHC) services and evaluated the association between the high assessment of PHC attributes, from the perspective of users, with health conditions and the use of health services in Brazil. This work is a cross-sectional study that analyzed data from the 2019 National Health Survey, in which 9,562 adults responded to the Primary Care Assessment Tool (PCATool). The association between high PHC assessment (general score ≥ 6.6) and health conditions and the use of services was tested, and it was found that the adult users who most use public PHC are between 40 and 59 years of age, women, with a low level of education, and brown. Those who best evaluated PHC were individuals who used the same service, who sought out services in the last 2 weeks, and who had been hospitalized. The greater use of health services points to a better assessment of PHC.

Laboratory exams of the National Health Survey: methodology of sampling, data collection and analysis. / Exames laboratoriais da Pesquisa Nacional de Saúde: metodologia de amostragem, coleta e análise dos dados.

INTRODUCTION: This article aims at describing the National Health Survey (Pesquisa Nacional de Saúde- PNS) methodology of collecting laboratory exams data. METHODOLOGY: A subsample of 25% of the census tracts was selected, according to the stratification of the PNS sample, with a probability inversely proportional to the difficulty of collection. The collection of blood and urine was done in the households by a laboratory agent, among residents selected for individual interview. Due to the difficulties found in the field work, the sample did not reach the minimum expected number in some strata, and a post-stratification procedure was proposed for the data analysis. RESULTS: The collection of biospecimens was performed in 8,952 individuals. Laboratory tests were: glycated hemoglobin; total cholesterol; LDL cholesterol; HDL cholesterol; serology for dengue; red blood cell count (erythrogram) and white series count (leukogram); high performance liquid chromatography (HPLC) for diagnosis of hemoglobinopathies; creatinine. Theexcretion of potassium, salt and sodium and creatinine was estimated in the urine. The database of laboratory exams was weighed and made publicly available on the Oswaldo Cruz Foundation's PNS website and can be accessed without prior authorization. CONCLUSION: The total subsample of laboratory exams is of great value, since it allowed us to establish national reference parameters adequate to sociodemographic and geographic characteristics of the Brazilian population, providing relevant and complementary information for the analysis of the health situation of Brazil.

INTRODUÇÃO: O artigo teve o objetivo de descrever a metodologia de coleta dos dados dos exames laboratoriais da Pesquisa Nacional de Saúde (PNS). METODOLOGIA: Foi selecionada uma subamostra de 25% dos setores censitários, obedecendo à estratificação da amostra da PNS, com probabilidade inversamente proporcional à dificuldade de coleta. A coleta de sangue e urina dos moradores selecionados para entrevista individual foi realizada nos domicílios por um agente de laboratório. Por conta das dificuldades encontradas no trabalho de campo,a amostra não atingiu número suficiente em alguns estratos da pesquisa, então para a análise dos dados foi proposto procedimento de pós-estratificação. RESULTADOS: A coleta de material biológico foi realizada em 8.952 indivíduos. Os exames realizados foram: hemoglobina glicada; colesterol total; colesterol LDL; colesterol HDL; sorologia para dengue; hemograma série vermelha (eritograma) e série branca (leucograma); cromatografia líquida de alta eficiência (HPLC) para diagnóstico de hemoglobinopatias; e creatinina. Na urina, estimativa de excreção de potássio, sal, sódio e creatinina. A base de dados dos exames laboratoriais foi ponderada e disponibilizada para os usuários no site da PNS da Fundação Oswaldo Cruz, sem necessidade de autorização prévia para uso. CONCLUSÃO: A subamostra total coletada é de grande valia, pois permitiu estabelecer parâmetros de referência nacionais adequados às características sociodemográficas e geográficas da população brasileira, fornecendo informações relevantes e complementares para a análise da situação de saúde do Brasil.

Estimation of salt intake in the Brazilian population: results from the 2013 National Health Survey. / Estimativa do consumo de sal pela população brasileira: resultado da Pesquisa Nacional de Saúde 2013.

OBJECTIVE: To estimate the salt intake in the Brazilian population according to their urinary sodium excretion. METHODS: The National Health Survey (2013) aimed to gather data on the health of adults (≥ 18 years) through a random selection of households. In each household, one adult was selected to have their biological data collected (anthropometry, blood pressure, and blood and urine tests). The urine sample was sent to a central laboratory to determine sodium (ion-selective electrode) and creatinine (Jaffé method) concentrations. Sodium excretion was estimated with the Tanaka equation. RESULTS: Urinary sodium and creatinine concentrations were measured in 8,083individuals (58% women). The mean salt intake was estimated at 9.34 g/day (95% confidence interval - 95%CI 9.27 - 9.41) and was higher in males (9.63 g/day; 95%CI 9.52 - 9.74) than in females (9.08 g/day; 95%CI 8.99 - 9.17). Wefound no significant differences regarding age group, ethnicity, or schooling. Salt intake was higher in the Southeast and South regions and lower in the Northeast and North. Only 2.4% (95%CI 2.0 - 2.8) of the sample consumed less than 5 g/day, and 58.2% (95%CI 56.7 - 59.6) of participants had an estimated intake of 8 to 12 g/day. CONCLUSION: The mean salt intake in the Brazilian population is approximately twice the recommended by the World Health Organization (5g/day).Given the association of high salt intake with hypertension and decreased renal function, these data indicate the need to adopt comprehensive public policies to reduce the consumption in the Brazilian population.

OBJETIVO: Estimar o consumo de sal na população brasileira pela excreção urinária de sódio. MÉTODOS: A Pesquisa Nacional de Saúde (2013) teve como objetivo obter dados de saúde de adultos (≥ 18 anos) por meio de seleção aleatória de domicílios. Em cada domicílio foi selecionado um adulto para coleta de dados biológicos (antropometria, pressão arterial, sangue e urina). A urina foi enviada para um laboratório central, para medida da concentração de sódio (eletrodo sensível) e creatinina (método de Jaffé). A estimativa da excreção de sódio foi feita com a equação de Tanaka. RESULTADOS: A dosagem urinária de sódio e de creatinina foi obtida em 8.083 indivíduos (58% mulheres). O consumo médio de sal foi estimado em 9,34 g/dia (intervalo de confiança de 95% - IC95% 9,27 - 9,41), sendo maior em homens (9,63 g/dia; IC95% 9,52 - 9,74) do que em mulheres (9,08 g/dia; IC95% 8,99 - 9,17). Não foram observadas diferenças importantes em relação à faixa etária, cor da pele nem escolaridade. O maior consumo foi detectado nas regiões Sudeste e Sul e o menor no Nordeste e Norte. Apenas 2,4% (IC95% 2,0 - 2,8) da amostra apresentou consumo inferior a 5 g/dia, e 58,2% (IC95% 56,7 - 59,6) dos participantes tiveram consumo estimado de 8 a 12 g/dia. CONCLUSÃO: O consumo médio de sal da população brasileira é, aproximadamente, o dobro da recomendação da Organização Mundial da Saúde (5g/dia). Tendo em vista a associação da alta ingestão de sal com hipertensão arterial e decréscimo da função renal, os dados apontam para a necessidade de adoção de políticas públicas abrangentes para redução desse consumo na população brasileira.

Mudanças no uso do tabaco entre adolescentes brasileiros e fatores associados: Pesquisa Nacional de Saúde do Escolar / Changes in tobacco use and associated factors among Brazilian adolescents: National Student Health Survey

Resumo O estudo objetiva comparar o consumo de diferentes produtos do tabaco entre os escolares adolescentes no Brasil em 2015 e 2019 e identificar os fatores associados ao seu uso. Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015 e 2019. Variáveis: uso atual de cigarro, uso de outros produtos do tabaco e uso de qualquer produto do tabaco. Foi usado o teste do Qui-quadrado de Pearson para verificar associação entre as variáveis, realizada análise bivariada e a multivariada por meio da regressão logística. O uso de cigarros se manteve estável entre 2015 (6,6%) e 2019 (6,8%). Mas houve aumento do uso de qualquer produto do tabaco (de 10,6% em 2015 para 14,8% em 2019), sendo o narguilé o mais frequente (7,8%) seguido do cigarro eletrônico (2,8%). O uso de cigarro foi mais elevado entre os adolescentes de 16 e 17 anos, com cor da pele preta e parda, que faltaram as aulas sem autorização, entre aqueles que relataram não ter amigos, que apresentavam outros fatores de risco como consumir bebidas alcoólicas e que eram fumantes passivos. A prevalência de tabagismo aumentou ao longo dos anos e foi associada com aspectos sociodemográficos e a outros comportamentos de risco à saúde, o que alerta para a necessidade de ações de promoção da saúde ao longo do ciclo de vida.

Abstract This cross-sectional study used data from Brazil's National Student Health Survey (PeNSE), from 2015 and 2019, to compare consumption of tobacco products among adolescent students in Brazil and identify associated factors. The study variables were current cigarette smoking, use of other tobacco products and use of any tobacco product. Pearson's Chi-square test was used to ascertain associations between the variables; bivariate and multivariate analyses were performed using logistic regression. Cigarette smoking remained stable between 2015 (6.6%) and 2019 (6.8%), but use of any tobacco product increased (from 10.6% in 2015 to 14.8% in 2019), involving particularly hookahs (7.8%) and e-cigarettes (2.8%). Cigarette smoking was greater among adolescents aged 16 and 17, whose skin colour was black or brown, who missed classes without permission, who reported having no friends, displayed other risk factors, such as drinking alcoholic beverages, or who were passive smokers. The prevalence of smoking has increased over the years and is associated with sociodemographic aspects and other health risk behaviour, highlighting the need for lifelong health promotion actions.

Cyberbullying entre escolares brasileiros: dados da Pesquisa Nacional de Saúde do Escolar, 2019 / Cyberbullying among Brazilian schoolchildren: data from the National Student Health Survey, 2019

Resumo O estudo analisou a associação entre Cyberbullying e fatores sociodemográficos, familiares, de saúde mental e comportamentais em escolares (13 a 17 anos) brasileiros. Trata-se de um estudo transversal com dados da PeNSE 2019. Realizou-se análise multivariada com regressão de Poisson. A prevalência de Cyberbullying foi de 13,2% e foi maior entre os adolescentes que sentiam que ninguém se preocupava com eles (RP=1,47; 1,36-1,59); se sentiam tristes (RP=1,5; 1,4-1,7); referiram que a vida não vale a pena (RP=1,71; 1,59-1,84); não tinham amigos (RP=1,68; 1,50-1,87); sofriam agressão dos pais (RP=1,54; 1,45-1,65); faltavam às aulas sem autorização (RP=1,13; 1,06-1,20); usavam tabaco (RP=1,19; 1,10-1,30); bebidas alcóolicas (RP=1,16; 1,08-1,25); drogas ilícitas (RP=1,14; 1,04-1,25); e tiveram relação sexual (RP=1,23; 1,14-1,33). Tiveram menor prevalência os adolescentes do sexo masculino (RP=0,85; 0,80-0,91), os mais velhos (16-17 anos) (RP=0,88; 0,82-0,95) e que reportaram ter supervisão dos pais no tempo livre (RP=0,78; 0,73-0,83). O Cyberbullying tem elevada prevalência e destaca-se a importância de monitorar a prática, estabelecendo ações de prevenção nas escolas.

Abstract This cross-sectional study assessed data from Brazil's 2019 National Student Health Survey to investigate associations between cyberbullying and sociodemographic, family, mental health, and behavioural factors among Brazilian schoolchildren. Multivariate analysis by Poisson regression found 13.2% prevalence of cyberbullying, which was higher among adolescents who felt nobody cared about them (PR=1.47; 1.36-1.59); felt sad (PR=1.5; 1.4-1.7); reported that life was not worth living (PR=1.71; 1.59-1.84); had no friends (PR=1.68; 1.50-1.87); suffered parental aggression (PR=1.54; 1.45-1.65); missed classes without permission (PR=1.13; 1.06-1.20); used tobacco (PR=1.19; 1.10-1.30); alcoholic beverages (PR=1.16; 1.08-1.25); or illicit drugs (PR=1.14; 1.04-1.25); or had sexual intercourse (PR=1.23; 1.14-1.33). Prevalence was lower among boys (PR=0.85; 0.80-0.91); those 16-17 years old (PR=0.88; 0.82-0.95); and who reported having parental supervision in their free time (PR=0.78; 0.73-0.83). Cyberbullying has a high prevalence, highlighting the importance of monitoring this practice and establishing prevention measures in schools.

Reference values for laboratory tests of cholesterol, glycosylated hemoglobin and creatinine of the Brazilian adult population. / Valores de referência para exames laboratoriais de colesterol, hemoglobina glicosilada e creatinina da população adulta brasileira.

INTRODUCTION: This article aims to estimate reference values for laboratory tests of cholesterol, glycosylated hemoglobin and creatinine for the Brazilian adult population. METHODS: A descriptive study carried out with laboratory data from the National Health Survey (Pesquisa Nacional de Saúde - PNS). Samples of blood and urine were collected in a PNS subsample of 8,952 individuals aged 18 years old or older. To determine the reference values, exclusion criteria were applied: presence of previous diseases and outliers, defined by values outside the range estimated by the mean ± 1.96 × standard deviation. Subsequently, reference values were calculated according to gender, age group and race/skin color. RESULTS: Differences in reference values according to gender were observed. Women had higher values of total cholesterol, LDL-c and HDL-c. Glycosylated hemoglobin showed similar values in relation to gender, and creatinine was higher among men. The mean reference values were higher in the elderly population, aged 60 years old or older. The mean, lower and upper limits of total cholesterol and fractions of non-white people were slightly lower. There was no difference according to race/skin color for glycosylated hemoglobin and creatinine. CONCLUSION: The establishment of national reference parameters for laboratory tests, adapted to the sociodemographic and geographic characteristics, provides relevant information for evaluation of diagnosis and treatment of chronic diseases in Brazil.

INTRODUÇÃO: Este artigo teve o objetivo de estimar valores de referência de exames laboratoriais de colesterol, hemoglobina glicosilada e creatinina para a população adulta brasileira. MÉTODOS: Estudo descritivo realizado com os dados laboratoriais da Pesquisa Nacional de Saúde (PNS). Foram coletadas amostras de sangue e urina em subamostra da PNS constituída de 8.952 indivíduos de 18 anos ou mais. Para determinar os valores de referência, aplicaram-se critérios de exclusão, como a presença de doenças prévias e dos outliers, definidos pelos valores fora do intervalo estimado pela média ± 1,96 × desvio padrão. Posteriormente, foram calculados os valores de referência segundo sexo, faixa etária e raça/cor. RESULTADOS: Observaram-se diferenças nos valores de referência de acordo com o sexo. O colesterol total, a lipoproteína de baixa densidade colesterol (LDL-c) e a lipoproteína de alta densidade colesterol (HDL-c) apresentaram valores mais elevados entre as mulheres. A hemoglobina glicosilada alcançou valores semelhantes segundo sexo, e a creatinina foi mais elevada entre os homens. Os valores médios de referência foram mais altos na população idosa, de 60 anos ou mais. A média e os limites inferiores e superiores do colesterol total e frações dos indivíduos não brancos foram ligeiramente mais baixos. Não houve diferença segundo raça/cor para hemoglobina glicosilada nem para creatinina. CONCLUSÃO: O estabelecimento de parâmetros nacionais de referência de exames laboratoriais, adaptados às características sociodemográficas e geográficas, fornece subsídios relevantes para a avaliação do diagnóstico e tratamento de doenças crônicas no Brasil.

Reference values for blood count laboratory tests in the Brazilian adult population, National Health Survey. / Valores de referência para exames laboratoriais de hemograma da população adulta brasileira: Pesquisa Nacional de Saúde.

OBJECTIVE: To describe reference values for blood counts obtained from laboratory tests in the Brazilian adult population according to laboratory results from the National Health Survey (Pesquisa Nacional de Saúde - PNS), by gender, age group and skin color. METHODS: The initial sample consisted of 8,952 adults. To determine the reference values, individuals with prior diseases and outliers were excluded. Mean values, standard deviation and limits were stratified by gender, age group and skin color. RESULTS: For red blood cells, men presented a mean value of 5.0 million per mm3 (limits: 4.3-5.8) and women, 4.5 million per mm3 (limits: 3.9-5.1). Hemoglobin levels were higher among men with a mean of 14.9 g/dL (13.0-16.9), and in women, 13.2 g/dL (11.5-14.9). The mean number of white blood cells among men was 6.142/mm3 (2.843-9.440) and 6.426/mm3 (2.883-9.969) for women. Other parameters showed close values between the genders. Regarding age groups and skin color, mean values, standard deviation and limits of the exams presented small variations. CONCLUSION: Hematological reference values based on the national survey allow for the establishment of specific reference limits for gender, age and skin color. The results presented here may contribute to the establishment of better evidence and criteria for the care, diagnosis and treatment of diseases.

Prevalence of altered total cholesterol and fractions in the Brazilian adult population: National Health Survey. / Prevalência de colesterol total e frações alterados na população adulta brasileira: Pesquisa Nacional de Saúde.

OBJECTIVE: To analyze the prevalence of altered total cholesterol and fractions levels in the Brazilian population, according to biochemical data from the National Health Survey. METHODS: A descriptive study, using data from the National Health Survey, collected between 2014 and 2015. Total cholesterol and fractions were analyzed and population prevalences of altered values according to socio-demographic variables were calculated. The cutoff points considered were: total cholesterol ≥ 200mg/dl; low-density lipoprotein LDL ≥ 130mg/dL and high-density lipoprotein HDL < 40mg/dL. RESULTS: The prevalence of total cholesterol ≥200mg/dL in the population was 32.7%, and higher in women (35.1%). The prevalence of altered HDL was 31.8%, 22.0% in females and 42.8% in males. LDL ≥ 130mg/dL was found in 18.6% and was higher in women (19.9%). The population aged 45 years old and older and those with low levels of education presented a higher prevalence of altered cholesterol. CONCLUSION: Altered values of total cholesterol and fractions were frequent in the Brazilian population, especially among women, the elderly and people with low levels of education. These results may guide control and preventative actions such as healthy eating, physical activity and treatment, all of which aim to prevent coronary diseases.

A prevalência de HDL alterado foi de 31,8%, sendo de 42,8% no sexo masculino e 22,0% no feminino. LDL≥ 130mg/dL foi observado em 18,6%, com prevalência mais elevada em mulheres (19,9%). População com idade de 45 anos ou mais e com baixa escolaridade apresentou maiores prevalências de colesterol com alterações. CONCLUSÃO: Valores de colesterol total e frações alterados foram frequentes na população brasileira, especialmente entre mulheres, idosos e pessoas de baixa escolaridade. Esses resultados poderão orientar as ações de controle e prevenção, como alimentação saudável, atividade física e tratamento, visando à prevenção de doenças coronarianas.

Prevalence of diabetes mellitus as determined by glycated hemoglobin in the Brazilian adult population, National Health Survey. / Prevalência de diabetes mellitus determinada pela hemoglobina glicada na população adulta brasileira, Pesquisa Nacional de Saúde.

OBJECTIVE: To analyze the prevalence of diabetes mellitus (DM) according to different diagnostic criteria, in the Brazilian adult population, according to laboratory results from the Brazilian National Health Survey. METHODS: Analysis of laboratory data from the National Health Survey, collected between 2014 and 2015. The prevalence of diabetes was calculated according to different diagnostic criteria. The prevalence of diabetes was calculated according to the criterion of glycosylated hemoglobin ≥ 6.5% or using medication, using Poisson regression and calculating crude and adjusted PR and 95%CI. RESULTS: The prevalence of diabetes according to different criteria varies from 6.6 to 9.4%. Intermediate or pre-diabetes hyperglycemia ranged from 6.8 to 16.9%. Considering laboratory criteria or medication use, the prevalence of DM was 8.4 (95%CI 7.65-9.11). The adjusted PR for gender, age, educational level and region was lower for males (PR 0.75; 95%CI 0.63 - 0.89), increased with age: 30 to 34 years (PR 2.32; 95% CI 1.33 - 4.07), 40 to 59 years PR 8.1; 95%CI 4.86 - 13.46), 60 years old or older (PR 12.6; 95%CI 7.1 - 21.0), and higher educational levels was protective (PR 0.8; 95%CI 0.6 - 0.9). Therewas a higher PR in the Central West Region (PR 1.3; 95%CI 1.04 - 1.7), in overweight people (PR 1.8; 95%CI 1.4 - 2.1), and in obese people (PR 3.3; 95%CI 2.6 - 4.1). CONCLUSION: The prevalence of diabetes was higher in females, people over 30 years of age, in populations with low educational levels, and people who were overweight and obese. The study advances in determining the diabetes situation in the country through laboratory criteria.

OBJETIVO: Analisar as prevalências de diabetes mellitus segundo diferentes critérios diagnósticos, na população adulta brasileira, segundo os resultados laboratoriais da Pesquisa Nacional de Saúde. MÉTODOS: Análise dos dados laboratoriais da Pesquisa Nacional de Saúde, coletados entre os anos de 2014 e 2015. Foram calculadas as prevalências de diabetes conforme diferentes critérios diagnósticos. Foram calculadas as prevalências de diabetes segundo o critério de hemoglobina glicosilada ≥ 6,5% ou em uso de medicamentos, empregando regressão de Poisson para o cálculo da razão de prevalência (RP) bruta e ajustada e intervalo de confiança de 95% (IC95%). RESULTADOS: A prevalência de diabetes segundo diferentes critérios pode variar 6,6 a 9,4%; e a hiperglicemia intermediária, ou pré-diabetes, de 6,8 a 16,9%. Usando-se o critério laboratorial ou uso de medicamentos, a prevalência de diabetes foi de 8,4%. A RP ajustada para sexo, idade, escolaridade e região foi menor no sexo masculino (RP = 0,75; IC95% 0,63 - 0,89); aumentou com a idade: 30 a 34 anos (RP=2,32; IC95% 1,33 - 4,07), 40 a 59 anos (RP = 8,1; IC95% 4,86 - 13,46), 60 anos ou mais (RP = 12,6; IC95% 7,1 - 21,0); e a escolaridade elevada foi protetora (RP = 0,8; IC95% 0,6 - 0,9). Maior RP foi encontrada na Região Centro-Oeste (RP = 1,3; IC95% 1,04 - 1,7) e naqueles com sobrepeso (RP = 1,8; IC95% 1,4 - 2,1) e obesidade (RP = 3,3; IC95% 2,6 - 4,1). CONCLUSÃO: A prevalência de diabetes foi maior no sexo feminino, naqueles com idade maior que 30 anos, em população com baixa escolaridade, com excesso de peso e obesidade. Os critérios laboratoriais são mais fidedignos para o conhecimento da situação real do diabetes no país.

Evaluation of renal function in the Brazilian adult population, according to laboratory criteria from the National Health Survey. / Avaliação da função renal na população adulta brasileira, segundo critérios laboratoriais da Pesquisa Nacional de Saúde.

OBJECTIVE: To evaluate the renal function of the Brazilian adult population, according to laboratory criteria of the National Health Survey (Pesquisa Nacional de Saúde - PNS). METHODOLOGY: A descriptive study was carried out with laboratory data from the PNS, which was collected between the years 2014 and 2015. Population prevalence of the serum creatinine (CR) and estimated glomerular filtration rate (GFR) according to sociodemographic variables, were analyzed from the PNS laboratory data. RESULTS: The sample consisted of 8,535 individuals aged 18 years old or older for the study of CR and 7,457 for the study of GFR. The GFR prevalence < 60 mL/min/1.73 m2 was 6.7% (95%CI 6.0 - 7.4), higher in women (8.2% 95%CI 7.2 - 9.2) than in men (5.0% 95%CI 4.2 - 6.0) p < 0.001, and in elderly > 60 years old it was 21.4%. For the values of CR ≥ 1.3 mg/dL in men were 5.5% (95%CI 4.6 - 6.5), and in women values of CR ≥ 1.1 mg/dL were 4.6% (95%CI 4.0 - 5.4), with no diference between the genders, p = 0.140. CONCLUSION: Results from the PNS laboratory identified a higher prevalence of chronic kidney disease in the Brazilian population than that estimated in self-reported studies, with higher GFR < 60 mL/min/1.73 m2 in women, and reaching one fifth of the elderly. These tests may be useful for the purpose of identifying the disease early on and thus preventing the progression of renal damage and reduce the risk of cardiovascular events and mortality.

OBJETIVO: O presente estudo avaliou a função renal da população adulta brasileira, segundo critérios laboratoriais da Pesquisa Nacional de Saúde (PNS). METODOLOGIA: Estudo descritivo realizado com os dados laboratoriais da PNS, coletados entre os anos de 2014 e 2015. Com base nos dados laboratoriais foram analisadas prevalências populacionais de creatinina sérica (CR) e estimativa da taxa de filtração glomerular (TFG), segundo variáveis sociodemográficas. RESULTADOS: A amostra foi de 8.535 indivíduos com idade de 18 anos ou mais para o estudo da CR e de 7.457 indivíduos para o estudo de TFG. A prevalência TFG < 60 mL/min/1,73 m2 foi de 6,7% (IC95% 6,0 - 7,4), foi mais elevada em mulheres (8,2% IC95% 7,2 - 9,2) do que em homens (5,0% IC95% 4,2 - 6,0) p < 0,001 e em idosos ≥ 60 anos foi de 21,4%. Os valores de CR ≥ 1,3 mg/dL em homens foram 5,5% (IC95% 4,6 - 6,5) e em mulheres foram de CR ≥ 1,1 mg/dL, de 4,6% (IC95% 4,0- 5,4), sem diferença estatística significativa nos valores de CR entre sexo, p = 0,140. CONCLUSÃO: Resultados laboratoriais da PNS identificaram prevalências mais elevadas da doença renal crônica na população brasileira do que o estimado em estudos autorreferidos. ATFG < 60 mL/min/1,73 m2 é mais elevada em mulheres e atinge um quinto dos idosos. Esses exames podem ser úteis no propósito de identificar precocemente a doença e, dessa forma, prevenir a progressão da lesão renal e reduzir o risco de eventos cardiovasculares e de mortalidade.
