Sleep quality and daytime sleepiness of high schoolers
Good sleep quality is essential for physical and mental well-being (GOMES et al., 2017). Therefore, poor sleep quality can trigger several consequences, including excessive daytime sleepiness (DEPIERI et al., 2016; GIORELLI et al., 2012). Hence, rest time among students is extremely important, keeping themselves healthy both physically and psychologically, leading to good results in the learning process (BRANDT et al., 2018). Furthermore, it is clear that in the last years of high school, the demand for good performance is great, since the National Secondary Education Examination (ENEM) is the mechanism for college admission.
To compare sleep quality and sleepiness levels among high school students of different grades.
This is an observational, descriptive, and cross-sectional study in a private school in Piauí. Three questionnaires were administered: 1. Participant data; 2. Pittsburgh Sleep Quality Index (PSQI-BR) to assess sleep quality (0-4=normal sleep, 5-9=poor sleep, and >10=sleep disturbance); 3. Epworth Sleepiness Scale (ESS) to investigate daytime sleepiness (>10=excessive daytime sleepiness). The data were analyzed using the JASP 13.0 program, the distribution of data normality was chartered by the Shapiro-Wilk test, the comparison among grades was carried out by the Kruskal-Wallis test and post-hoc by the Tukey test. The research was approved by the Research Ethics Committee registered under No. 3.846.627.
Fifty-five students participated in the research: n=21 first grade, n=19 second grade and n=15 third grade. Average age was 15 ± 1 years old. The PSQI per grade was: (6.6 ± 3.0); (5.8 ± 2.8) and (9.2 ± 4.0), respectively, with p=0.235. The Epworth was: (11.5 ± 3.3); (9.2 ± 4.0) and (10.3 ± 4.7), respectively, with p=0.188. Average sleep time/night: (6:54h ± 1:24h); (5:48h ± 1:30h) and (5:48h ± 1:12h), respectively, with p=0.05 between first with second and third grade.
Sleep quality among high school students is poor and showed no difference among grades. The level of daytime sleepiness is moderate and there is no difference between grades. Sleep time per night was reduced in the whole group, but with less time in second and third grades.
