Medical students using mobile phones more than two hours per day had more sleep disturbance, latency, and daytime dysfunction than those using them less, especially females.

Plain English Summary

Summary written for general audiences

The study enrolled 100 medical students divided into cases with more than two hours of daily mobile phone use (n=57) and controls with two hours or less (n=43), and assessed sleep quality using the Pittsburg Sleep Quality Index. Differences between groups were tested with the Mann-Whitney U test and Student's t-test, and correlations were analyzed using Spearman's rank correlation with significance set at p<0.05. Evening mobile phone use showed a significant negative association with sleep quality (r=-0.606, p=0.042), where higher PSQI scores indicate worse sleep.

Why This Matters

The researchers aimed to assess the extent of mobile phone use among medical students and its correlation with sleep patterns. The authors suggested that using a mobile phone for more than two hours per day may cause sleep deprivation and daytime sleepiness that could affect cognitive and learning abilities. The study noted that exposure to radiofrequency electromagnetic fields from mobile phones has amplified public and scientific debate about possible adverse health effects.

Study Details

The study was designed with the objective of assessing the extent of mobile phone use amongst medical students and finding correlation if any between the hours of usage of mobile to sleep pattern and quality.
