Prevalência de bullying e fatores associados em escolares brasileiros, 2015 / Prevalence of bullying and associated factors among Brazilian schoolchildren in 2015

RESUMO

Resumo O estudo analisou a prevalência de sofrer bullying e fatores associados em escolares brasileiros. Trata-se de análise da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2015 em amostra nacional com 102.301 alunos do 9º ano. Foi calculada a prevalência de sofrer bullying e foi feita inicialmente análise bivariada com estimativas de razões de chance (OR) e IC95% para estimar as associações entre vitimização e variáveis sociodemográficas, contexto familiar, violência familiar, saúde mental e comportamentos de risco. Posteriormente, procedeu-se ao modelo de regressão logística múltipla, inserindo as variáveis de interesse com (p < 0,20). No modelo final ajustado (ORa) permaneceram variáveis com p < 0,05. A prevalência de bullying foi de 7,4%. A análise multivariada mostrou que quem tem maior chance de sofrer bullying são os escolares do sexo masculino, com 13 anos, da escola pública, filhos de mães sem escolaridade, que trabalham, com relato de solidão, sem amigos, com insônia; que sofreram agressão física dos familiares, faltaram as aulas sem avisar aos pais, usaram tabaco. Predominaram vítimas de 13 anos, com contexto social e familiar desfavorável, mostrando cenário de vulnerabilidades, demandando apoio de redes de proteção social, escolar e famíliar.

ABSTRACT

Abstract This study analyzed the prevalence of bullying and associated factors among Brazilian schoolchildren using data produced by the 2015 National School Health Survey (PeNSE, acronym in Portuguese) consisting of a national sample of 102,301 eighth grade students. The prevalence of bullying was calculated and bivariate analysis was performed using a 95% confidence level to determine the association between victimization and socio-demographic variables and other variables relating to family background, mental health, and risk behaviors. Multivariate analysis was then conducted using the biologically plausible variables of interest. For the final model, variables that obtained p-values of < 0.05 were maintained. The prevalence of bullying was found to be 7.4%. The results of the multivariate analysis showed that boys aged 13 years studying in public schools who worked and whose mother did not have any schooling were more likely to be bullied, as were schoolchildren who felt lonely, had no friends, suffered from insomnia, skipped lessons without parental permission, and who smoked. Victims of bullying were predominantly 13-year-olds from an unfavorable social and family background, painting a picture of vulnerability that calls for support from social protection networks, schools and families alike .
