Sleep Quality and Associated Factors among Adolescents
Abstract
Introduction: This study aimed to investigate sleep quality and sleep patterns in adolescents. The second aim was to find out whether there was an association between sleep quality, sleep patterns, dietary habits, food consumptions, and anthropometric measurements in an adolescent population. Material and methods: This cross-sectional study was conducted on 346 adolescents. Data was recorded with a questionnaire form. The questionnaire form included items on adolescents’ characteristics, sleep patterns, dietary habits, food consumptions, and anthropometric measurements. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Results: Sleep duration of >8 hours (67.6%) and sleep latency of 15 minutes (53.8%) were the most commonly identified sleeping patterns. The mean PSQI score was 3.07±2.54. PSQI scores revealed poor sleep quality in 13.6% of participants. A significant difference was observed between age, disease diagnosed by physician, skipping main meals, having regular breakfast, and PSQI score (p<0.05). PSQI score was found to be significantly associated with spending time in front of the computer and regular sleep. The amount of daily saturated fatty acid was statistically significantly lower (p=0.040) in individuals in the good PSQI. Conclusions: The vast majority of adolescents had good sleep quality. Sleep duration of adolescents was consistent with the recommended need. Individual factors, dietary habits, food consumption, and screen times were factors associated with sleep quality. This current study results support the development of interventions to help adolescents improve sleep quality. We recommend further investigation to clarify this finding.
