Bullying and associated factors among Brazilian adolescents: analysis of the National Adolescent School-based Health Survey (PeNSE 2012) / Bullying e fatores associados em adolescentes brasileiros: análise da Pesquisa Nacional de Saúde do Escolar (PeNSE 2012)

ABSTRACT

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. .

RESUMO

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. .
