ABSTRACT: Objectives: To
evaluate sleep quality in relation to lifestyle characteristics including
consumption of energy drinks and other caffeinated beverages among Peruvian
college students. Methods: A total of 2458 college students were invited to
complete a self-administered questionnaire that collected information about a variety
of behaviors including consumption of energy drinks, caffeinated and alcoholic
beverages. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep
quality. Logistic regression procedures were used to estimate odds ratios
(OR) and 95% confidence intervals (95% CI) for poor sleep quality in relation
to lifestyle characteristics. Results: A total of 965 males and 1493 female
students were enrolled in the study. 52.0% of males and 58.4% of females experienced
poor sleep quality (p = 0.002). Females (OR = 1.28; 95% CI 1.08-1.51) and
those who reported consuming ≥3 stimulant beverages per week (OR = 1.88; 95% CI
1.42-2.50) had higher odds of poor sleep quality. Students who consumed 1-19
alcoholic beverages monthly (OR = 1.90; 95% CI 1.46-2.49) had a higher odds
of long sleep latency. Consumption of ≥3 stimulant beverages per week was
associated with daytime dysfunction due to sleep loss (OR = 1.45; 95% CI 1.10-1.90), short sleep duration (OR = 1.49; 95% CI 1.14-1.94), and use of sleep
medication (OR = 2.10; 95% CI 1.35-3.28). Conclusions: Consumption of energy
drinks, other caffeinated beverages and alcoholic beverages are risk factors of
poor sleep quality. Increased awareness of these associations should promote interventions
to improve students’ lifestyle habits, including consumption of alcoholic and
caffeinated beverages, and overall health.
