Introduction:

sleep can be altered with the use of psychotropic drugs and coffee consumption, so this study aimed to analyze the quality of sleep of university students and its relationship with the consumption of these substances, a cross-sectional study was carried out with university students aged 18 years or over.

Methods:

Data collection took place through an online questionnaire between April and June 2019. The dependent variable was sleeping quality and the independent variables were consumption of psychoactive medications and high consumption of coffee. For the association analyses, Poisson regression with robust variance was used, with calculation of the prevalence ratio (PR) and confidence interval at 95 % (95 % CI).

Results:

among the evaluated students (N=2721), the prevalence of poor sleep quality was 75.6 %. The consumption of psychoactive drugs and high consumption of coffee was 11.2 % and 14.1 %, respectively. Poor sleep quality was more prevalent in students who use psycho-active medications (PR 1.11; 95 % CI 1.06 to 1.16), consuming a high amount of coffee (PR 1.06; 95 % CI 1.01- 1.11), or use one of the two substances (RP 1.10; 95 % CI 1.06-1.15).

Conclusion:

the present study showed an association between poor sleep quality and the use of psychoactive drugs and higher coffee consumption in college students, which, together with the high prevalence of poor sleep quality in college students, demonstrates the importance of proper management of the use of these products, as well as actions to prevent and resolve sleep disorders.
