RESUMO

OBJECTIVE: To evaluate the association between the consumption of psychoactive substances (tobacco, alcohol and illicit drugs) and demographic variables, mental health and family context among school-aged children. METHODS: The National Adolescent School-based Health Survey was held with a national sample of 109,104 students. Data regarding demographic variables, family background and mental health were collected. Logistic regression was used to evaluate the associations of interest. RESULTS: Multivariate analyses showed that alcohol consumption was higher among girls, drug experimentation was more frequent among boys and that there was no difference between sexes for smoking. Being younger and mulatto were negatively associated with the use of tobacco, alcohol and illicit drugs. Also negatively associated with such risk behaviors were characteristics of the family context represented by: living with parents, having meals together and parental supervision (when parents know what the child does in their free time). Moreover, characteristics of mental health such as loneliness and insomnia were positively associated with use of tobacco, alcohol and illicit drugs. Not having friends was positively associated with use of tobacco and illicit drugs and negatively associated with alcohol use. CONCLUSIONS: The study shows the protective effect of family supervision in the use of tobacco, alcohol and drugs and, on the contrary, the increasing use of substances according to aspects of mental health, such as loneliness, insomnia and the fact of not having friends. The study's findings may support actions from health and education professionals, as well as from the government and families in order to prevent the use of these substances by adolescents.

RESUMO

OBJECTIVE: To compare the prevalence of major risk and protection factors for chronic non-communicable diseases in school-aged children in Brazilian capitals surveyed in the National Adolescent School-based Health Survey in its two editions, 2009 and 2012. METHODS: The frequencies, with Confidence Interval of 95%, of the following demographic variables were compared: food intake, body image, physical activity, smoking, alcohol and other drugs. Prevalence was compared in the two editions of the survey. RESULTS: The proportion of students who attend two physical education classes a week was maintained at 49% between 2009 and 2012, increasing in public schools from 50.6% (95%CI 49.8 - 51.4) to 52.5% (95%CI 49.2 - 55.7), and decreasing in private schools. There was no change in the proportion of students who watch two hours or more of television daily, about 80%. As for body image, there was no change between the two editions, and about 60% considered themselves being of normal weight. There was a reduction in the percentage of adolescents who experienced cigarettes, from 24.2% (95%CI 23.6 - 24.8) to 22.3% (95%CI 21.4 - 23.2), and the prevalence of smoking was maintained at about 6% (there was no statistical difference between 2009 and 2012). The consumption of beans, fruits, sweets and soft drinks also decreased. Frequency of drug experimentation was of 8.7% (95%CI 8.3 - 9.1) in 2009, and 9.6% (95%CI 9.0 - 10.3) in 2012, with no difference between confidence intervals, and the frequency of alcohol experimentation was maintained at about 70%; the percentage of use in the past 30 days was also maintained at around 27%. CONCLUSION: 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.

RESUMO

OBJECTIVE: To estimate the prevalence of bullying from the victim's perspective in Brazilian school children and to analyze its association with individual and family context variables. METHODS: An analysis of the data on 109,104 adolescents, obtained by the National Adolescent School-based Health Survey, held in schools in 2012, was carried out. An association model between bullying and explanatory variables was tested in different contexts: sociodemographic, risk behaviors, mental health and family context. Univariate and multivariate analyzes were performed, calculating the Odds Ratio and confidence intervals. RESULTS: The prevalence of bullying found in this study was of 7.2% (95%CI 6.6 - 7.8). A higher chance of bullying was found among male students (OR = 1.58; 95%CI 1.51 - 1.66), with an inverse relation between age and bullying, with the magnitude of risk among adolescents younger than 13 years of age being higher when compared to those with 16 years of age or more. Of individual risk behaviors, only being a smoker remained in the final model (OR = 1.11; 95%CI 1.01 - 1.23). Mental health variables associated with bullying were: feeling lonely (OR = 2.66; 95%CI 2.52 - 2.81), insomnia (OR = 1.92; 95%CI 1.80 - 2.05), not having friends (OR = 1.71; 95%CI 1.54 - 1.89), and, in the family context, those who skip class without telling their parents (OR = 1.13; 95%CI 1,07 - 1,19) and those who suffer physical abuse by family members (OR = 2.03; 95%CI 1.91 - 2.146). CONCLUSION: Bullying was associated to male students, younger, of black color, smokers, with mental health vulnerabilities and victims of domestic violence. This suggests the need for a holistic approach from education and health professionals, parents and the community in seeking measures for the prevention of bullying.

OBJETIVO: Comparar as prevalências dos principais fatores de risco e proteção para doenças crônicas não transmissíveis em escolares nas capitais brasileiras, investigados na Pesquisa Nacional de Saúde do Escolar nas suas duas edições, 2009 e 2012. MÉTODOS: Foram comparadas as frequências com Intervalo de Confiança de 95% das variáveis sóciodemograficas e dos seguintes comportamentos: consumo alimentar, imagem corporal, atividade física, tabagismo, consumo de álcool e outras drogas. As prevalências foram comparadas nas duas edições da pesquisa. RESULTADOS: A proporção de alunos que praticam duas ou mais aulas de educação física foi mantida em 49% entre 2009 e 2012. Não houve mudança nos que assistem duas horas ou mais de televisão diária, cerca de 80%. Quanto à imagem corporal, não houve mudança nas duas edições, e cerca de 60% se consideraram com peso normal. Houve uma redução no percentual de adolescentes que experimentou cigarros de 24,2% (IC95% 23,6 - 24,8) para 22,3% (IC95% 21,4 - 23,2), e a prevalência de fumantes foi mantida em cerca de 6%. O consumo de feijão, frutas, guloseimas e refrigerantes também reduziu. A experimentação de drogas foi de 8,7% (IC95% 8,3 - 9,1) em 2009 e de 9,6% (IC95% 9,0 - 10,3) em 2012, e a frequência de experimentação de bebidas alcoólicas foi mantida em cerca de 70%; a porcentagem de uso nos últimos 30 dias também foi mantida, em cerca de 27%.

OBJETIVO: Estimar a prevalência de bullying, sob a perspectiva da vítima, em escolares brasileiros e analisar sua associação com variáveis individuais e de contexto familiar. MÉTODOS: Foram analisadas informações de 109.104 adolescentes obtidas da Pesquisa Nacional de Saúde do Escolar (PeNSE), 2012. Foi testado modelo de associação entre o bullying e variáveis explicativas nos seguintes domínios: sociodemográfico, comportamentos de risco, saúde mental e contexto familiar. Foram feitas analises uni e multivariada, calculando-se os odds ratio e respectivos intervalos de confiança. RESULTADOS: A prevalência de bullying foi de 7,2% (IC95% 6,6 - 7,8). Maior chance de bullying foi encontrada entre escolares do sexo masculino (OR = 1,58; IC95% 1,51 - 1,66), com uma relação inversa entre idade e bullying, sendo maior a magnitude do risco entre menores de 13 anos quando comparados aos de 16 ou mais anos. Dos comportamentos de risco individuais, apenas ser fumante se manteve no modelo final (OR = 1,11; IC95% 1,01 - 1,23). As variáveis de saúde mental associadas foram: sentir-se solitário (OR = 2,66; IC95% 2,52 - 2,81), ter insônia (OR = 1,92; IC95% 1,80 - 2,05), não ter amigos (OR = 1,71; IC95% 1,54 - 1,89) e, no contexto familiar os que faltam às aulas sem avisar os pais (OR = 1,13; IC95% 1,07 - 1,19) e relataram sofrer agressão física dos familiares (OR = 2,03; IC95% 1,91 - 2,16). CONCLUSÃO: O bullying mostrou-se associado aos escolares do sexo masculino, mais jovens, de cor preta, fumantes, além daqueles que apresentam vulnerabilidades no campo da saúde mental e de violência doméstica, o que sugere necessidade de uma abordagem holística de profissionais da educação, saúde, pais e comunidade na busca de medidas para sua prevenção. .

OBJETIVO: Avaliar a associação entre o consumo de substâncias psicoativas (tabaco, bebidas alcoólicas e drogas ilícitas) e variáveis demográficas, saúde mental e o contexto familiar em escolares. MÉTODOS: A Pesquisa Nacional de Saúde do Escolar foi realizada em uma amostra nacional de 109.104 alunos. Foram coletadas informações referentes às variáveis demográficas, contexto familiar e saúde mental. A regressão logística múltipla foi utilizada para avaliar as associações de interesse. RESULTADOS: As análises multivariadas mostraram que o consumo de álcool foi mais elevado entre as meninas, experimentação de drogas foi mais elevada entre os meninos e não houve diferença entre os sexos para tabagismo. Idade mais jovem e ser da cor parda estiveram associados negativamente ao uso do tabaco, bebidas alcoólicas e drogas ilícitas. Também estiveram associadas negativamente a tais comportamentos de risco as características do contexto familiar representadas por: morar com os pais, fazer refeição em conjunto e supervisão parental (os pais saberem o que o filho faz no tempo livre). Por outro lado, características da saúde mental como a solidão e insônia estiveram associadas positivamente ao uso do tabaco, bebidas alcoólicas e drogas ilícitas. Não ter amigos associou-se positivamente ao uso do tabaco e drogas ilícitas, e negativamente ao uso do álcool. CONCLUSÕES: O estudo aponta o efeito protetor da supervisão familiar no uso de tabaco, álcool e drogas, e, ao contrário, o aumento do consumo em função de aspectos relacionados à saúde mental, como solidão, insônia e não ter amigos. Os achados do estudo podem apoiar ações dos profissionais de saúde, educação, ...

RESUMO

UNLABELLED: Adolescence is typically a developmental phase characterized by change and experimentation and therefore varying exposure to health hazards. We aimed at estimating the prevalence of protective and risk health behaviors of adolescents interviewed in the 2009 National Adolescent School-based Health Survey (PeNSE). PeNSE, a partnership between the Instituto Brasileiro de Geografia e Estatística (IBGE) and the Ministry of Health, using a PDA-based self-administered questionnaire collected information on 60,973 students enrolled at 1,453 public and private schools in the 27 state capitals and the Federal District. RESULTS: Among the food items most often consumed ( > or = 5 days per week), were beans (62.6%) and fruit (31.5%), but also sweets (58.3%) and soft drinks (37%), 43.1% of the students were sufficiently physically active but 79.5% spent >2 hours per day in front of the TV. As for drug use, 6.3% reported being current tobacco smokers, 27% drank alcoholic beverages regularly and 8.7% had used illicit drugs at least once. These results should guide stakeholders and policy makers in the development and implementation of programs and recommendations aimed at curtailing unhealthy exposures of adolescents in Brazil.

RESUMO

The aim of this study was to describe the nutritional status of adolescents in the 9th year of public and private schools of the Brazilian capitals and its association with socio-demographic variables. By means of a self-completed questionnaire, information related to sex, race, age, public/private school, macro-region of the country, maternal education and family possessions were recorded. Measures of weight and height were measured according to standardized procedures. Height for age and body mass index for age was evaluated according to the World Health Organization reference. Anthropometric measurements of 58,971 adolescents were obtained, of which 2.9% were stunted and 2.9% underweight. There was 23.0% of overweight and 7.3% of obesity, which were higher in the South and Southeast regions. Deficits in height and weight, overweight and obesity were more prevalent in boys. The deficits were higher at public schools while overweight and obesity at private ones. Adolescents whose mothers were less educated or from poorer families had greater deficits in height and the reverse occurred with overweight and obesity. The findings about the deficits, overweight and obesity highlight the need for nutritional interventions designed to reach this stage of life.

RESUMO

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 por cento comem feijão, apenas 31,5 por cento consomem frutas, 58,3 por cento comem guloseimas e 37 por cento tomam refrigerantes; 43,1 por cento dos alunos são suficientemente ativos fisicamente e 79,5 por cento gastam mais de duas horas diárias em frente à TV. Em relação a tabaco e drogas: 6,3 por cento são fumantes atuais, 71,4 por cento dos alunos disseram já ter experimentado alguma bebida alcoólica. O consumo atual de bebida alcoólica foi de 27 por cento e as drogas ilícitas foram usadas alguma vez na vida em 8,7 por cento. 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.

RESUMO

Objetivou-se descrever o estado nutricional dos adolescentes da 9ª série de escolas públicas e privadas das capitais brasileiras e sua associação com variáveis sociodemográficas. Por meio de questionário autopreenchido, foram registradas informações sobre sexo, raça/cor, idade, escola pública/privada, macrorregião do país, escolaridade materna e posse de bens familiares. Peso e altura foram aferidos segundo procedimentos padronizados. A altura para idade e o Índice de Massa Corporal para idade foram avaliados segundo critérios da Organização Mundial da Saúde. Obtiveram-se medidas antropométricas de 58.971 adolescentes, sendo que 2,9 por cento apresentaram déficit estatural e 2,9 por cento magreza. O excesso de peso foi de 23,0 por cento e a obesidade de 7,3 por cento, sendo mais altos no Sul e no Sudeste do país. Déficits de altura e peso, excesso de peso e obesidade foram mais prevalentes nos meninos. Os déficits foram superiores nas escolas públicas, e o excesso de peso e a obesidade nas privadas. Adolescentes cujas mães eram de menor escolaridade ou de famílias mais pobres apresentaram maior déficit de altura; o inverso ocorreu com o excesso de peso e a obesidade. Prevalências de déficits, excesso de peso e obesidade ressaltam a necessidade de intervenções nutricionais direcionadas para esta fase da vida.

RESUMO

A demografia dos povos indígenas no Brasil é ainda muito pouco conhecida nos seus mais diversos aspectos. Nos últimos anos, vem acontecendo uma ampliação de interesse pelo tema, com a publicação de diversos estudos sobre demografia dos "indígenas" com base nos dados censitários. Uma dificuldade metodológica importante diz respeito à expansão da amostra dos censos, já que as terras indígenas não foram definidas originalmente como áreas de ponderação. Este trabalho apresenta estimativas para as variáveis do questionário da "amostra", considerando um conjunto de setores censitários pertencentes a terras indígenas e utilizando como estudo de caso as Terras Xavante localizadas no leste de Mato Grosso, constituídas por seis áreas não-contíguas. Trata-se de um exercício metodológico que visa comparar e avaliar as estimativas produzidas segundo os pesos gerados na época de divulgação do Censo 2000 e os novos pesos calculados a partir de metodologia aqui apresentada. Do ponto de vista metodológico, esse procedimento é inovador, pois pode ser útil para estimar, com base nos dados da amostra do Censo 2000, características de áreas não-contíguas e diferentes daquelas definidas para a expansão da amostra como originalmente realizada e divulgada pelo IBGE.

The demography of the Brazilian native peoples is still uncharted territory in its numerous and diversified aspects. There has been growing interest in the topic in recent years, with the publication of a number of studies on the demography of native peoples, on the basis of census data. One major methodological difficulty is the problem of expanding the census samples, since the lands of the native peoples were not originally defined as weighted areas. This article presents estimates for the variables on the questionnaire for the "sample," considering one set of census sectors belonging to the lands of native peoples, using as a case study the lands of the Xavante Indians, consisting of six non-contiguous areas located in the eastern part of the Brazilian State of Mato Grosso. This methodological exercise is designed to compare and evaluate the estimates produced according to the weights generated at the time of disclosure of the Census 2000 results and the new weights calculated on the basis of the methodology presented here. From the methodological point of view, this procedure is innovative as it might be useful for estimating, on the basis of the data from the sample on the 2000 Census, characteristics of areas that are non-contiguous and different from those defined for expanding the sample as originally conceived and published by the Brazilian Census Office.
