Psychoactive substance use, family context and mental health among Brazilian adolescents, National Adolescent School-based Health Survey (PeNSE 2012).

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.

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, ...
