Abstract:

〔Abstract〕Objective: To investigate and evaluate the health hazards of mobile phone use in a medical college, and to provide
reference for reducing health risks. Methods: A stratified random sampling survey was conducted by distributing self- designed
"Perception Questionnaire" which includes the basic information about students, the cell phone functions used continuously, and
subjective perceptions of health hazards after a continued usage. The SPSS 18.0 software was used to analyze the reliability and validity
of the scale with Cronbach's alpha coefficient and factor analysis. Results: It indicated that the scale had good internal consistency and
validity, with the Cronbach's α coefficient, cumulative explained rate, communality and max factor loading greater than 0.90, 70%,
0.50 and 0.55, respectively. More than 80% of respondents continue to use such mobile phone features as "social networking",
"watching video", "game and entertainment" and "reading and learning" for a long time（≥1 h）. The health risks for neck/shoulder and
eye were moderate, while risks for ear and nervous system were mild after a long time of mobile phone use. Conclusion: It is essentials
for students to use mobile phones reasonably, trying to avoid mobile phone dependence, and develop good habits of mobile phone use,
which is conducive to reducing heath risks and hazards.
