ASSOCIATION BETWEEN CONSUMPTION OF PSYCHOACTIVE DRUGS AND COFFEE WITH THE SLEEP QUALITY OF UNIVERSITY STUDENTS
Caffeine and psychoactive drugs are substances commonly used to increase alertness, especially in individuals with poor sleep quality. The consumption of these substances, especially coffee, is more common in the adult population, increasing with age and overload of activities. However, such a strategy can be used by young adults, as university students, to stay awake for the performance of their academic activities.
To evaluate the association between consumption of psychoactive drugs and coffee and the quality of sleep of university students.
Cross-sectional study, conducted in 2019, with undergraduate students from the State University of Londrina, Brazil. The dependent variable was sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI) scale, with a score > 5 considered poor sleep quality. The independent variables were the consumption of psychoactive drugs and the high coffee consumption (four or more doses per day). Poisson regression, with calculation of the prevalence ratio (PR) was used for the association analysis. As adjustment variables, sex, age, course period, satisfaction with the course, body mass index and indicative of depression were used.
Of the 12,536 students with active enrollment, 2,721 participated in this study, most of them females (68.1%). The use of psychoactive drugs was 11.2% and high coffee consumption by 14.1%. Poor sleep quality was identified in 75.6% of students. The prevalence of poor sleep quality was higher in students who reported using psychoactive drugs (PR 1.11; 95% CI 1.06-1.16), high coffee consumption (PR 1.06; 95% CI 1, 01-1.11) and use of psychoactive medications or high coffee consumption (PR 1.10; 95% CI 1.06-1.15).
The results found in this investigation indicate an association between the consumption of psychoactive drugs and coffee with poor sleep quality, suggesting that these substances may be being used inappropriately or exaggerated, but also that their use may be a strategy to minimize harmful effects in students with sleep disorders.
