How do teenagers sleep? Analysis of factors related to sleep disorders in a group of Polish high school students.

Unlabelled: Insomnia is the most common sleep disorder in the adolescent population. Resulting from a complex interplay of genetic, biological, social, and environmental factors, it affects disturbances in everyday functioning in many aspects of life. The aim of the study was to analyze the factors related to the occurrence of insomnia among high school students.

Material: The study was conducted among 2364 high school students aged between 14 and 19 years old (the average age 17.92 ± 1.10), of which there were 2068 girls and 295 boys.

Method: Athens Insomnia Scale (AIS) and authorial demographic data questionnaire involved questions about physical activity during the day, smoking, frequency of upper respiratory tract infections, problems with concentration and memory, school achievements, and the use of mobile devices at bedtime were used to assess examined parameters. The scale and questionnaires were shared on-line via social media.

Results: Analyzing the results obtained in the study group, the average score of 8.42 ± 4.16 was obtained in the AIS, which allows the assessment of sleep disorders bordering on normal. After division into groups of girls and boys, 8.38 ± 4.56 points were obtained, respectively for girls and 8.43 ± 4.27pts. for boys - the difference was not statistically significant. Similarly, statistically significant differences were not found when dividing the groups into the one in which adolescents used the phone just before bedtime and the one that did not use it. The act of sleeping alone or with another person in the room also did not differentiate the groups statistically, as well as the place of residence. Statistically significant worse results in the AIS scale were obtained by people who declared worse physical activity during the day and smoking cigarettes, as well as those who reported more frequent problems with concentration and memory, had worse school performance and suffered from upper respiratory infections more often.

Conclusions: 1). Sleep disorders may be related to factors such as smoking cigarettes or lack of physical activity, as well as difficulties in concentrating attention, memory disorders or worse academic performance and a tendency to contract upper respiratory tract infections. 2). Elimination of factors that may adversely affect the quality of sleep is particularly important in the group of adolescents, in whom the developing structures of the central nervous system may be particularly sensitive to deficiencies in this area. 3). Exploration of the interplay of study duration, screen time, and semester-specific stressors on sleep quality could yield further insights.
