Factors Affecting Sleep Quality in High School Students and its Relationship with Nomophobia

Objective: A good sleep quality is essential for biopsychosocial health. Studies show that most high school students have poor sleep quality, and recently, nomophobia has also become common in high school students. This study aims to determine the factors affecting sleep quality and its relationship with nomophobia among high school students. Materials and Methods: This cross-sectional study was conducted in 428 high school students. Pittsburgh sleep quality index and nomophobia scale were used for data collection. Factors affecting sleep quality were evaluated with both univariate and multivariate logistic regression analyses. Results: The sleep quality in 65.7% of students was poor. Poor sleep quality was found to be increased by 1.70 (1.04-2.81) times in females; 6.82 (2.65-17.55) times in those having flu or other upper respiratory tract infections; 3.17 (1.50-6.68) times in those with gastrointestinal disorders; 4.40 (1.48-13.10) times in those overweight; and 2.99 (1.36-6.57) times in those with severe nomophobia (p<0.05). Conclusion: Poor sleep quality in high school students is dramatic. Providing counselling on sleep hygiene, especially for risk groups and their families, will improve sleep quality among high school students.
