[Perinatal mortality in Brazil in 2018: an epidemiological analysis according to the modified Wigglesworth classification]. / Mortalidade perinatal no Brasil em 2018: análise epidemiológica segundo a classificação de Wiggleworth modificada.

Perinatal mortality includes fetal mortality and early neonatal mortality (0 to 6 days of life). The study described perinatal deaths in Brazil in 2018 according to the modified Wigglesworth classification. The data sources were the Brazilian Mortality Information System and the Brazilian Information System on Live Births. Fetal mortality and perinatal mortality rates were calculated per 1,000 total births (live births plus stillbirths) and the early neonatal mortality rate per 1,000 live births, compared using their respective 95% confidence intervals (95%CI). Perinatal deaths were classified in groups of antepartum causes, congenital anomalies, prematurity, asphyxia, and specific causes. For each group of causes, the study calculated the number of deaths by weight group, in addition to mortality rates and respective 95%CI, besides the spatial distribution of mortality rates by state of Brazil. A total of 35,857 infant deaths were recorded, of which 18,866 (52.6%) were early neonatal deaths, while stillbirths totaled 27,009. Perinatal deaths totaled 45,875, for a mortality rate of 15.5‰ births. The highest mortality rate (7.6‰; 7.5‰-7.7‰) was observed in the antepartum group, followed by prematurity (3.6‰; 3.6‰-3.7‰). In the antepartum group, 14 of the 27 states (eight of which in the Northeast and four in the North) presented perinatal mortality rates above the national rate. Perinatal mortality in Brazil was high, and most deaths could have been prevented with investment in prenatal and childbirth care.

A mortalidade perinatal engloba a mortalidade fetal e a neonatal precoce (0 a 6 dias). Este estudo descreveu os óbitos perinatais ocorridos no Brasil em 2018, segundo a classificação de Wigglesworth modificada. As fontes de dados foram os Sistemas de Informações sobre Mortalidade e sobre Nascidos Vivos. Foram calculadas as taxas de mortalidade fetal e perinatal por mil nascimentos totais (nascidos vivos mais natimortos) e a taxa de mortalidade neonatal precoce por mil nascidos vivos, e comparadas usando seus respectivos intervalos de 95% de confiança (IC95%). Os óbitos perinatais foram classificados nos grupos de causas anteparto, anomalias congênitas, prematuridade, asfixia e causas específicas. Foi calculado, para cada grupo de causas, o número de óbitos por faixa de peso, além das taxas de mortalidade e os respectivos IC95%, e feita a distribuição espacial das taxas de mortalidade por Unidade da Federação (UF). Foram registrados 35.857 óbitos infantis, sendo 18.866 (52,6%) neonatais precoces; os natimortos somaram 27.009. Os óbitos perinatais totalizaram 45.875, perfazendo uma taxa de mortalidade de 15,5‰ nascimentos. A maior taxa de mortalidade (7,6‰; 7,5‰-7,7‰) foi observada no grupo anteparto, seguido da prematuridade (3,6‰; 3,6‰-3,7‰). No grupo anteparto, 14 das 27 UFs (sendo oito na Região Nordeste e quatro na Região Norte) apresentaram as taxas de mortalidade perinatal acima da nacional. A taxa de mortalidade perinatal no Brasil mostrou-se elevada, e a maioria dos óbitos poderia ser prevenida com investimento em cuidados pré-natais e ao nascimento.

Rape and pregnancy of girls aged up to 13 years in Brazil: characteristics and implications in health during gestation, delivery and childbirth. / Estupro e gravidez de meninas de até 13 anos no Brasil: características e implicações na saúde gestacional, parto e nascimento.

Sexual violence against children and adolescents is a serious threat to the rights and full health of this age group. This study aims to describe the characteristics of mothers aged up to 13, and analyze the profile of cases of notified rape in this age range and repercussions of this violence during pregnancy and childbirth. It is a comparative study of the characteristics of gestation and childbirth of girls aged up to 13 who have had children, without or with notification of rape, in the Violence & Accidents Vigilance (VIVA) System of the Brazilian Case Registry Database (Sistema de Informação de Agravos de Notificação - SINAN). A significant percentage (67.5%) of the girls aged up to 13 with children were of the black race/color category. There was repeated violence in 58.2% of cases. The notified rape victims have a higher percentage of birth by cesarean section, late onset and a lower number of prenatal consultations; and their babies had lower birthweight and lower 1-minute Apgar scores than mothers without rape notification. Rape of children and adolescents is an important risk factor that has repercussions during pregnancy, and complications in delivery and childbirth.

Resumo A violência sexual contra crianças e adolescentes representa uma grave ameaça aos direitos e à saúde integral desse grupo etário. O objetivo do presente estudo foi descrever as características de mães com até 13 anos, analisar o perfil dos casos de estupro notificado nessa mesma faixa etária e as repercussões dessa violência durante a gravidez e parto. Trata-se de estudo comparativo das características da gestação e parto de meninas de até 13 anos que tiveram filhos, sem e com notificação de estupro no Sistema de Vigilância de Violências e Acidentes do Sistema de Informação de Agravos de Notificação (VIVA/SINAN). O percentual de meninas até 13 anos que tiveram filhos foi maior em negras (67,5%). A violência de repetição ocorreu em 58,2%. As vítimas de estupro notificadas tiveram maiores percentuais de cesárea, início tardio e menor número de consultas de pré-natal; e seus bebês tiveram peso ao nascer e Apagar do 1º minuto piores que das mães, sem notificação de estupro. O estupro de criança e adolescente é um fator de risco importante que repercute na gestação, em complicações no parto e no nascimento.

Microcefalia no Brasil: prevalência e caracterização dos casos a partir do Sistema de Informações sobre Nascidos Vivos (Sinasc), 2000-2015 / Microcephaly in Brazil: prevalence and characterization of cases from the Information System on Live Births (Sinasc), 2000-2015 / Microcefalia en Brasil: prevalencia y caracterización de casos a partir del Sistema de Informaciones sobre Nacidos Vivos (Sinasc), 2000-2015

OBJETIVO: descrever os coeficientes de prevalência e caracterizar os casos de microcefalia ao nascer no Brasil, no período 2000-2015. MÉTODOS: estudo descritivo com dados do Sistema de Informações sobre Nascidos Vivos (Sinasc). Foram calculados coeficientes segundo regiões e características das mães e nascidos vivos (NV). RESULTADOS: a média anual de casos de microcefalia foi 164 no período 2000-2014, enquanto em 2015 foram registrados 1.608 casos (54,6 casos por 100 mil NV). Coeficientes mais elevados foram observados entre prematuros (81,7; IC95%72,3; 92,2), nascidos de mães pretas (70,9; IC95%58,5; 85,9) ou pardas (71,5; IC95%67,4; 75,8), com idades ≤19 (70,3; IC95%63,5; 77,8) ou ≥40 anos (62,1; IC95%46,6; 82,6), ≤3 anos de estudo (73,4; IC95%58,2; 92,4) e residentes na região Nordeste (138,7; IC95%130,9; 147,0). CONCLUSÃO: o elevado número de casos de microcefalia registrado em 2015 reforça a importância do Sinasc e do aprimoramento do sistema de vigilância das anomalias congênitas.

OBJECTIVE: to describe the prevalence coefficients and characterize cases of microcephaly at birth in Brazil from 2000-2015. METHODS: this is a descriptive study with data from the Information System on Live Births (Sinasc). The coefficients were calculated by region and characteristics of mothers and live births (LB). RESULTS: the annual average number of microcephaly cases was 164 for the period 2000-2014, whilst in 2015, 1,608 cases were registered (54.6 cases per 100 thousand LB). Higher coefficients were observed among preterm babies (81.7; 95%CI 72.3;92.2), born from black-skinned (70.9; 95%CI 58.5;85.9) or to brown-skinned (71.5; 95%CI67.4;75.8) women, to women aged ≤19 (70.3; 95%CI 63.5;77.8) or ≥40 (62.1; 95%CI 46.6;82.6), with ≤3 years of study (73.4; 95%CI 58.2;92.4) and residents in the Northeast region (138.7; 95%CI 130.9;147.0). CONCLUSION: the high number of microcephaly cases in 2015 reinforces the importance of Sinasc and the need to improve the surveillance of congenital anomalies.

The causes of bullying: results from the National Survey of School Health (PeNSE).

OBJECTIVE: to identify the characteristics and reasons reported by Brazilian students for school bullying. METHOD: this cross-sectional study uses data from an epidemiological survey (National Survey of School Health) conducted in 2012. A total of 109,104 9th grade students from private and public schools participated. Data were collected through a self-applied questionnaire and the analysis was performed using SPSS, version 20, Complex Samples Module. RESULTS: the prevalence of bullying was 7.2%, most frequently affecting Afro-descendant or indigenous younger boys, whose mothers were characterized by low levels of education. In regard to the reasons/causes of bullying, 51.2% did not specify; the second highest frequency of victimization was related to body appearance (18.6%); followed by facial appearance (16.2%); race/color (6.8%); sexual orientation 2.9%; religion 2.5%; and region of origin 1.7%. The results are similar to those found in other sociocultural contexts. CONCLUSION: the problem belongs to the health field because it gathers aspects that determine the students' health-disease-care continuum.

A priority health index identifies the top six priority risk and related factors for non-communicable diseases in Brazilian cities.

BACKGROUND: In Brazil, 72% of all deaths in 2007 were attributable to non-communicable diseases (NCD). We used a risk and related factor based index to prioritize NCD prevention programs in the combined 26 capital cities and the federal district (i.e., Brasilia) of Brazil. METHODS: We used 2006-2011 data (adults) from census and Brazil's surveillance of 12 NCD risk factors and 74 disease group mortality. The risk and related factors were: smoking, physical inactivity, overweight-obesity, low fruits and vegetables intake, binge drinking, insufficient Pap smear screening (women aged 25 to 59 years), insufficient mammography screening (women aged 50 to 69 years), insufficient blood pressure screening, insufficient blood glucose screening, diagnosis of hypercholesterolemia, diagnosis of hypertension and diagnosis of diabetes. We generated six indicators: intervention reduction of the risk factor prevalence, intervention cost per person, prevalence of risk factor, deaths attributable to risk factor, risk factor prevalence trend and ratio of risk factor prevalence between people with and without a high school education. We transformed risk and related factor indicators into priority scores to compute a priority health index (PHI). We implemented sensitivity analysis of PHI by computing it with slightly altered formulas and altering values of indicators under the assumption of bias in their estimation. We ranked risk factors based on PHI values. RESULTS: We found one intermediate (i.e., overweight-obesity) and six top risk and related factors priorities for NCD prevention in Brazil's large urban areas: diagnosed hypertension, physical inactivity, blood pressure screening, diagnosed hypercholesterolemia, smoking and binge drinking. CONCLUSION: Brazil has already prioritized the six top priorities (i.e., hypertension, physical inactivity, blood pressure screening, hypercholesterolemia, smoking and binge drinking) and one intermediate priority (i.e., overweight-obesity) for NCD prevention identified in this report. Because effective interventions to reduce disease burden associated with each of the six priority risk factors are available, strategies based on these interventions need to be sustained in order to reduce NCD burden in Brazil. PHI can be used to track NCD prevention and health promotion actions at the local and national level in Brazil and in countries with similar public health surveillance systems.

Bullying in Brazilian school children: analysis of the National Adolescent School-based Health Survey (PeNSE 2012).

OBJECTIVE: To describe the victimization and bullying practice in Brazilian school children, according to data from the National Adolescent School-based Health Survey and to compare the surveys from 2009 and 2012. METHODS: This is a cross-sectional study with univariate and multivariate analyzes of the following variables: to have been treated badly by colleagues, to have been bullied and to have bullied other children. The following independent variables were analyzed: age, sex, race/color, type of school, maternal education. Prevalence rates were compared between the editions of 2009 and 2012 of the survey. RESULTS: Of all the adolescents analyzed, 27.5% have not been treated well by peers at school, with greater frequency among boys (OR = 1.50), at the age of 15 years (OR = 1.29) and 16 (OR = 1.41), public school students (OR = 2.08), black (OR = 1.18) and whose mothers had less education; 7.2% reported having been bullied, with a greater chance in younger students (13 years old), male (OR = 1.26), black (OR = 1.15) and indigenous (OR = 1.16) and whose mothers had less education; 20.8% reported to have bullied other children, with a greater chance for older students, at the age of 14 (OR = 1.08) and 15 years (OR = 1.18), male (OR = 1.87), black (OR = 1.14) and yellow (OR = 1.15), children of mothers with higher education, private school students. There was an increase of bullying in the Brazilian capitals, from 5.4 to 6.8%, between 2009 and 2012. DISCUSSION: The occurrence of bullying reveals that the Brazilian school context is also becoming a space of reproduction of violence, in which it is crucial to act intersectorally and to articulate social protection networks, aiming to face this issue.

Alcohol consumption among Brazilian Adolescents according to the National Adolescent School-based Health Survey (PeNSE 2012).

OBJECTIVE: To describe the prevalence of alcohol consumption among Brazilian students and identify the sociodemographic factors associated alcohol consumption in the last 30 days. METHODS: Cross-sectional study with a cluster sample of 109,104 9th grade students in Brazilian public and private schools in 2012. The prevalence and 95% confidence intervals of the indicators of alcohol consumption were analyzed. RESULTS: Of the students analyzed, 50.3% (95%CI 49.0 - 51.6) experimented one dose of alcoholic beverages or more. The consumption of alcohol in the last 30 days was 26.1% (95%CI 24.5 - 27.7), and there was no difference in prevalence between students from public and private schools. Drunkenness episodes were reported by 21.8% (95%CI 21.1 - 22.5) of the students. The perception of students about the negative reaction of their family if they came home drunk occurred in 89,7% (95%CI 89,6 - 89,9) of cases, and 10% (95%CI 8.9 - 11.1) of them reported having problems with their families or friends because they had been drinking. Among adolescents aged less than 14 years old, the first alcoholic drink intake was predominantly at 12 to 13 years old. The most common way to get a drink was at parties, with friends, buying in them in supermarkets, stores or bars and at home. The consumption of alcohol in the last 30 days was less frequent among boys, increasing with age.

OBJECTIVE: To describe the prevalence of alcohol consumption among adolescent school students and identify its individual and contextual associated factors. METHODS: The present research used data from the 2009 National School Health Survey (PeNSE), which included a sample of 59,699 9th grade students in Brazilian capitals and the Federal District. The association between regular alcohol consumption and independent explanatory variables was measured by means of the Pearson's Chi-square test, with a 0.05 significance level. The explanatory variables were divided into four groups based on affinity (sociodemographic; school and family context; risk factors; and protection factors). A multivariate analysis was carried out for each group, always adjusting for age and sex. Variables with p < 0.10 were used in the final multivariate analysis model. RESULTS: The highest alcohol consumption in the preceding 30 days was independently associated with pupils aged 15 years (OR = 1.46) and over, female (OR = 1.72), white, children of mothers with higher education, studying in private school, students who had tried smoking (OR = 1.72) and drug use (OR = 1.81), with regular tobacco consumption (OR = 2.16) and those who have had sexual intercourse (OR = 2.37). The factors related to family were skipping school without parental knowledge (OR = 1.49), parents not knowing what children do in their free time (OR = 1.34), having fewer meals with their parents (OR = 1.22), reporting that parents do not care (OR = 3.05), or care little (OR = 3.39) if they go home drunk, and having suffered domestic violence (OR = 1.36). CONCLUSIONS: The results reinforce the importance of viewing alcohol consumption among adolescents as a complex, multifactorial and socially determined phenomenon.

Alcohol consumption among Brazilian Adolescents according to the National Adolescent School-based Health Survey (PeNSE 2012) / Consumo de álcool entre adolescentes brasileiros segundo a Pesquisa Nacional de Saúde Escolar (PeNSE 2012)

OBJECTIVE: To describe the prevalence of alcohol consumption among Brazilian students and identify the sociodemographic factors associated alcohol consumption in the last 30 days. METHODS: Cross-sectional study with a cluster sample of 109,104 9th grade students in Brazilian public and private schools in 2012. The prevalence and 95% confidence intervals of the indicators of alcohol consumption were analyzed. RESULTS: Of the students analyzed, 50.3% (95%CI 49.0 - 51.6) experimented one dose of alcoholic beverages or more. The consumption of alcohol in the last 30 days was 26.1% (95%CI 24.5 - 27.7), and there was no difference in prevalence between students from public and private schools. Drunkenness episodes were reported by 21.8% (95%CI 21.1 - 22.5) of the students. The perception of students about the negative reaction of their family if they came home drunk occurred in 89,7% (95%CI 89,6 - 89,9) of cases, and 10% (95%CI 8.9 - 11.1) of them reported having problems with their families or friends because they had been drinking. Among adolescents aged less than 14 years old, the first alcoholic drink intake was predominantly at 12 to 13 years old. The most common way to get a drink was at parties, with friends, buying in them in supermarkets, stores or bars and at home. The consumption of alcohol in the last 30 days was less frequent among boys, increasing with age. CONCLUSION: The study demonstrates the extension of alcohol as a problem, making it important to advance in measures such as the improvement of protective legislation for children and adolescents and stricter enforcement in alcohol sales. .

Sexual health of adolescents according to the National Survey of School Health.

The objective of this study was to describe situations related to sexual health of adolescents, according to the National Survey of School Health (PeNSE). It is a cross-sectional study performed by the Brazilian Institute of Geography and Statistics (IBGE), in partnership with the Ministry of Health that involved 60,973 students and 1,453 public and private schools. Data analysis points out that 30.5% (95%CI 29.9-31.2) of the adolescents had already had sexual relations sometime in their lives, being more frequent for males (43.7%; 95%CI 42.7-44.7) than females (18.7%; 95%CI 18.0-19.4), especially those who go to public schools (33.1%; 95%CI 32.4-33.9), aged 15 years or older (47.3%; 95%CI 45.7-48.9) and 16 years (63.5%; 95%CI 61,5-65.4). The sexual initiation age was early and 40.1% (95%CI 38.8-41.4) reported having had only one partner in life. The use of condoms in the last sexual relation was high both for protective (75.9%; CI95% 74.8-76.9) and contraceptive methods (74.7%; 95%CI 73.6-75.7). It is necessary to emphasize actions for promoting sexual health towards adolescents in order to minimize vulnerabilities.

Family and the protection from use of tobacco, alcohol, and drugs in adolescents, National School Health Survey.

This study evaluates the relation between the use of tobacco, alcoholic beverages and illicit drugs and family protective factors. Data from the National School Health Survey (PeNSE) were analyzed in a sample of 60,973 students at the freshman year of high school, from public and private schools of Brazilian state capitals. Most adolescents lived with both their parents and about a third lived in households only with their mothers. Half the parents or responsible parties are aware of what adolescents do in their free time. Living with both parents is a protective factor for smoking, drinking, and drug use. Family supervision is also important for the prevention of such behavior. Sharing a meal with parents or responsible parties most days of the week and the fact that the parents know what the adolescents have done in their free time in the past 30 days are also protective factors. Students that miss classes without telling their parents have higher chances of using tobacco, alcohol, and drugs. The family plays an essential role to prevent tobacco, alcohol, and drug use, and to promote health among teenagers.
