Perception of quantity and quality of sleep and their association with health related quality of life and life satisfaction during adolescence

Abstract

Objectives: This study aims to analyse differences between sleep duration and sleep quality and their association with health related quality of life and life satisfaction during adolescence. Methods: The Health Behaviour in School-Aged Children (HBSC) survey is based on a self-completed questionnaire. The participants in the present study were 3631 students (53.1% were girls) in the 8th and 10th grades at school; the mean age was 14.8 years (range 13-18). Results: The present results add to previous ones that both the duration and the perceived quality of sleep have impact upon the perception of quality of life and the perception of life satisfaction. Conclusions: These results are substantially important for sleep hygiene and for recommendations for adolescents, parents, health and education professionals and public policies. It is now widely recommended that adolescents must sleep at least 8 hours per night, what this study allow to recommend is that the perception of quality of that sleep is equally important, and this leads to another set of recommendations to increase sleep quality, that include not exercising or practising sports in the evenings, avoiding conflicts at home in the evenings, no going to bed worried, no having caffeine and other energetic drinks in the evening, not abusing screen time after dinner or in bed. These recommendations are important to assure sleep duration and perceived quality and therefore the perception of wellness and life satisfaction, having an additional impact on health and on school achievement.
