RESUMEN
Objective: To investigate the relationship between mobile phone addiction and sleep quality of military medical students, so as to provide evidence for improving their mental health. Methods: A total of 237 cadets from freshman to senior majored in medicine were tested by the Pittsburgh sleep quality index (PSQI) scale and mobile phone addiction tendency scale (MPATS). Results: Eventually, 227 valid questionnaires were collected, with the effective response rate being 95.8%. The mean score of PSQI was 5.78±2.26, and the mean score of MPATS was 38.65±11.32. Females had a worse sleep quality than male military medical students (6.12±2.11 vs 5.49±2.35, P < 0.05). Junior cadets had the highest MPATS score (42.51 ± 10.81). The score of PSQI was positively correlated with the score of MPATS among military medical students (r 0.280, P<0.01). Regression analysis showed that mobile phone addiction had significant impact on sleep quality of military medical students (P < 0.01). Conclusion: Mobile phone overuse has a negative impact on sleep quality among military medical students, especially in females. It is necessary to strengthen the management mobile phone use among junior cadets.
