RESUMO
RESUMO Objetivo Estimar a prevalência e os fatores associados ao uso de metilfenidato para neuroaprimoramento entre estudantes universitários. Métodos Amostra aleatória simples de discentes da Universidade Federal de Minas Gerais (n=438), convidados a responder um questionário online sobre o consumo de metilfenidato. A coleta ocorreu de setembro de 2014 a janeiro de 2015. A amostra foi descrita em termos de proporções, médias e desvio padrão. A análise multivariada foi realizada utilizando o algoritmo Classification and Regression Tree para classificação dos casos de uso do metilfenidato para neuroaprimoramento em grupos, com base nas variáveis de exposição. Resultados Dos 378 alunos incluídos, 5,8% (n=22) declararam ter feito uso de metilfenidato para neuroaprimoramento, sendo 41% (9/22) nas 4 semanas anteriores à pesquisa. A situação da moradia foi a variável mais associada ao uso de metilfenidato para neuroaprimoramento. Relataram o uso do metilfenidato para neuroaprimoramento e outros fins nas 4 semanas anteriores à pesquisa 11 estudantes, sendo que 27% não apresentaram prescrição médica para adquiri-lo. Conclusão O uso de metilfenidato para neuroaprimoramento ocorre no meio acadêmico brasileiro e deve ser considerado sério problema de saúde pública, principalmente diante dos riscos de danos e efeitos adversos associados ao seu uso.ABSTRACT Objective To estimate the prevalence of and factors associated with the use of methylphenidate for cognitive enhancement among undergraduate students. Methods Simple random sample of students of the Universidade Federal de Minas Gerais (n=438), invited to answer an online questionnaire about the use of methylphenidate. Data collection occurred from September 2014 to January 2015. The sample was described by means of proportions, means and standard deviations. A multivariate analysis was performed using the Classification and Regression Tree algorithm to classify the cases of use of methylphenidate for cognitive enhancement in groups, based on the exposure variables. Results Out of 378 students included, 5.8% (n=22) reported using methylphenidate for cognitive enhancement; in that, 41% (9/22) in the 4 weeks prior to the survey. The housing situation was the variable most often associated with the use of methylphenidate for cognitive enhancement. Eleven students reported using methylphenidate for cognitive enhancement and other purposes 4 weeks prior to the survey, 27% of whom had no medical prescription to purchase it. Conclusion The use of methylphenidate for cognitive enhancement is frequent among Brazilian undergraduate students and should be considered a serious public health problem, especially due to risks of harm and adverse effects associated with its use.
