Cross-Sectional Study on Analysis of the Prevalence and Influencing Factors of Sleep Disorders among College Students in a Certain University in China.

Background: Maintaining good sleep quality is crucial for improving the efficiency of college students. Therefore, this cross-sectional study aims to elucidate the prevalence of sleep disorders among students and analyze its risk factors.

Methods: A cross-sectional study was conducted on college students between March 2022 and December 2022. A well-designed questionnaire was filled out by college students from a certain university in China. Students whose scores on the Pittsburgh Sleep Quality Index (PSQI) scale exceeded 8 were included in the sleep disorder group (SD group), while those with lower were included in the non-sleep disorder group (ND group). Furthermore, single-factor analysis was used to investigate the relationship between general information and sleep disorders. Additionally, multifactor logistic regression was utilized to identify the independent risk factors contributing to the occurrence of sleep disorders among college students.

Results: We observed that the total PSQI score was 7.00 ± 2.17, and the incidence of sleep disorders was 38% among 326 college students. The level of sleep disorders was low (35.89%), scoring 2 or 3 in each component. A high number of students (78.22%) did not use sleep medication in the past 1 month. The level of daytime dysfunction was low (25.76%), scoring 2 or 3 in each section. The differences between the two groups in terms of academic performance, economic level, risk of smartphone addiction, pressure level, family relationship, and physical activity were statistically significant (p < 0.05). Furthermore, multifactor logistic regression analysis indicated that several factors, such as academic performance, smartphone addiction risk, pressure level, and family relationship, were independent risk factors affecting the occurrence of sleep disorders among college students (p < 0.05).

Conclusion: The prevalence of sleep disorders among students in a certain university is 38%. Factors affecting sleep disorders include poor academic performance, high smartphone addiction risk and stress levels, and challenging family relationship.
