Este artigo apresenta os principais resultados da Pesquisa Nacional de Saúde do Escolar (PeNSE). Aplicou-se questionário em uma amostra de conglomerados de 60.973 estudantes do 9º ano do ensino fundamental de escolas públicas e privadas das capitais dos estados brasileiros e do Distrito Federal, entre março e junho de 2009. Analisam-se prevalências e intervalos de confiança de 95% (IC95%) das situações de violência envolvendo adolescentes. Foram identificadas as seguintes situações: insegurança no trajeto casa-escola (6,4%; IC95%: 6,1%-6,8%) e na escola (5,5%; IC95%: 5,2%-5,8%); envolvimento em brigas com agressão física (12,9%; IC95%: 12,4%-13,4%), com arma branca (6,1%; IC95%: 5,7%-6,4%) ou arma de fogo (4,0%; IC95%: 3,7%-4,3%); agressão física por familiar (9,5%; IC95%: 9,1%-9,9%). As situações de violência foram mais prevalentes entre estudantes do sexo masculino. Houve grande variação segundo as cidades estudadas. Os adolescentes estão expostos a diferentes manifestações de violência nas instituições que supostamente deveriam garantir sua proteção e desenvolvimento saudável e seguro - a escola e o lar. Esses resultados visam apoiar medidas de promoção à saúde e prevenção desses fatores de risco.

A adolescência é marcada por transformações e exposição a diversas situações e riscos para a saúde. O estudo atual estima a prevalência dos principais fatores de risco e proteção à saúde dos adolescentes entrevistados em 2009 na Pesquisa Nacional de Saúde do Escolar (PeNSE). A PeNSE, parceria do Instituto Brasileiro de Geografia e Estatística (IBGE) com o Ministério da Saúde, usou questionário autoaplicável em palmtop coletando informação de 60.973 estudantes em 1.453 escolas públicas privadas nas 27 capitais. RESULTADOS: consumo de alimentos em cinco dias ou mais na semana: 62,6% comem feijão, apenas 31,5% consomem frutas, 58,3% comem guloseimas e 37% tomam refrigerantes; 43,1% dos alunos são suficientemente ativos fisicamente e 79,5% gastam mais de duas horas diárias em frente à TV. Em relação a tabaco e drogas: 6,3% são fumantes atuais, 71,4% dos alunos disseram já ter experimentado alguma bebida alcoólica. O consumo atual de bebida alcoólica foi de 27% e as drogas ilícitas foram usadas alguma vez na vida em 8,7%. Esses dados geram evidências para orientar a implementação de políticas públicas e realizar ações para minimizar a exposição de fatores de risco dos adolescentes brasileiros.

ABSTRACT: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.

Resumo O objetivo deste trabalho é descrever a exposição ao tabagismo de participantes da Pes 6.3% (95%CI:5,74)

In the Brazilian capitals, the vast majority of prevalence of risk factors were kept stable in the two editions of the National Survey of School. These data generate evidence to guide the implementation of public policies to minimize the exposure of adolescents to risk factors.

The aim of this study is to identify and describe the occurrence of bullying among students in the 9th year (8th grade) from public and private schools from 26 Brazilian state capitals and the Federal District. It is a cross-sectional study involving 60,973 students and 1,453 public and private schools. Data analysis indicates that 5.4% (IC95%: 5.1%-5.7%) of students reported having suffered bullying almost always or always in the last 30 days, 25.4% (IC95%: 24.8%-26.0%) were rarely or sometimes the victim of bullying and 69.2% (IC95%: 68.5%-69.8%) of students felt no humiliation or provocation at school. The capital with higher frequency of bullying was Belo Horizonte (6.9%; IC95%: 5,9%-7,9%), Minas Gerais, and the lowest was Palmas (3.5%; IC95%: 2.6%-4.5%), Tocantins. Boys reported more bullying (6,0%; IC95%: 5.5%-6.5%) compared with girls (4,8%; IC95%: 4.4%-5.3%). There was no difference between public schools 5.5% (IC95%: 5.1%-5.8%) and private (5.2%) (IC95%: 4.6%-5.8%), except in Aracaju, Sergipe, that show more bullying in private schools. The findings indicate an urgent need for intersectoral action from educational policies and practices that enforce the reduction and prevention of the occurrence of bullying in schools in Brazil.

BackgroundVery few studies have examined the role of school, household and family contexts in youth smoking in middle-income countries.MethodsThis work describes smoking exposure among 59 992 high school students who took part in the Brazilian Survey of School Health and investigates contextual factors associated with regular smoking, defined as smoking cigarettes at least once in the past 30 days. The explaining variables were grouped into: socio-demographic characteristics, school context, household context and family rapport. Variables independently associated with smoking in each context were identified by multiple logistic regression analysis.Results53% of the total sample were girls, 89% were aged 13–15 years. 24% had already experimented with cigarettes, 50% before the age of 12 years. The prevalence of regular smoking was 6.3% (95% CI 5.87 to 6.74), with no sex variation. Smoking was not associated with either the mother's education or the index of household assets. In the multivariable analysis, studying at a private school, the possibility of purchasing cigarettes at school and skipping of classes without parents' consent increased the chances of smoking. In the household context, living with both parents was negatively associated with smoking, while having smoking parents and exposure to other people's smoking was positively related to smoking. In the family context, parental unawareness of what the adolescent was doing increased smoking, but having meals with the mother one or more days per week and parents' negative reactions to adolescent smoking reduced the chances of smoking.ConclusionThe results reinforce the role of school, household and family contexts in youth smoking behaviours and will help improve public health policies aimed at preventing smoking and health promotion in adolescents.

The prevalence of labor among students is high. Socioeconomical disadvantages increase the chances of early working. Early working is also associated to health damaging behavior, violent situations, sleeping problems, and social isolation. Adolescents who study and work experiment expositions that may affect distinct health dimensions and perpetuate disadvantages over lifetime.
