Prevalência e padrões do uso de metilfenidato em universitários do Rio Grande do Sul

Abstract

Objectives: To assess the prevalence and patterns of methylphenidate use among university students in Rio Grande do Sul. Methods: This was a cross-sectional study conducted in Passo Fundo, RS, Brazil. Participants included undergraduate students from any public or private higher education institution in the state of Rio Grande do Sul, aged 18 years or older, of all genders. Data were collected through an online questionnaire. Statistical analysis consisted of absolute (n) and relative (%) frequency distributions of the variables, with corresponding 95% confidence intervals (95% CI). Results: The sample (n=134) was predominantly composed of female students, aged between 18 and 27 years, mostly enrolled in health-related undergraduate programs. The prevalence of methylphenidate use was 29% (IC 21-37). Most students reported using the medication under medical recommendation (57,9%, IC 43-75), with 100% (IC 100) reporting increased concentration and 94.9% (IC 88-100) perceiving improved academic performance. Conclusion: This study demonstrated a high prevalence of methylphenidate use among university students, higher than that reported in the literature. Furthermore, the usage patterns observed are similar to those described in previous studies and highlight the need for socio-educational initiatives regarding the use of psychostimulant medications.
