Poor sleep quality among high students is associated with impaired quality of life

Introdução

Quality of life and sleep quality have a bidirectional relationship. Contemporary society presents a wide variety of challenges to teenagers’ quality of life and sleep quality.

Objetivo

The purpose of the present study was to assess reported sleep duration, sleepiness, quality of life and sleep quality among high school students.

Métodos

High school students from a private school in Sao Paulo were invited to participate. Subjects answered three questionnaires: World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). In addition, students were asked about average sleep duration.

Resultados

Out of 220 students, 152 (42% men) accepted to participate. Mean reported sleep duration was 7:36 ± 0:53 hours. Most students (53.4%) had excessive daytime sleepiness (defined as an ESS > 10). In addition, most students (73.8%) reported poor sleep quality (defined as a PSQI > 4). There was a negative correlation between sleep quality and the different domains of WHOQOL-BREF: Physical (r= -0.636; p < 0.001); Psychological (r = - 0.548; p < 0.001); Social (r = - 0.219; p = 0.011); Environment (r = - 0.327; p < 0.001). Daytime sleepiness was associated with physical, psychological and environment WHOQOL-BREF domains (r ranging from -0.260 to -0.343; p < 0.01) and sleep quality (r = 0.311; p < 0.001).

Conclusões

High school students report poor sleep quality and daytime sleepiness, which affects quality of life. Interventions to improve sleep quality and quality of life among high school students are warranted.
