この研究は、2014年に、イラン北東部の5つの医科大学の労働衛生安全学科の学生(n=450)を対象に、携帯電話使用状況および睡眠質および健康全般に関する質問票調査を実施した。健康関連情報の収集には、ピッツバーグ睡眠質指標(PSQI)、一般健康質問票(GHQ)を用いた。その結果、学生の半数で睡眠質レベルが低く、大部分の学生が自分は不健康と考えていた;携帯電話の過剰使用とGHQおよびPSQIの総スコアの間に有意な相関が見られた、などの知見を報告している。

研究の目的(著者による)

A cross-sectional study was conducted in Iran to investigate the association between the excessive use of mobile phones and the quality of sleep and general health among students.

詳細情報

The students filled in questionnaires to assess sleep quality (Pittsburgh's Sleep Quality Index) and health conditions (General Health Questionnaire).
Exposure was assessed by Cell Phone Overuse Scale. (Remark EMF-Portal: Details of the questionnaire are missing and the classification into low use, medium use and overuse is not given. It is unclear whether the behavior with mobile phones or the exposure to electromagnetic fields were investigated in the study.)

結論(著者による)

Half of the students reported a poor level of sleep quality and 68% of them reported an unhealthy general health status. Overall, 21 out of 450 students (4,6%) were overusers of mobile phones.
An association between the excessive use of mobile phones and the total score and the four subscales of general health (somatic symptoms, social dysfunction, anxiety, and severe depression) and the quality of sleep was observed. Furthermore, the quality of sleep has a simultaneous effect on each of the four scales of the general health.
