[Effects of electromagnetic radiation from cellular telephone handsets on symptoms of neurasthenia].

Abstract

In order to study the effects of electromagnetic radiation from cellular telephone handsets on symptoms of neurasthenia, 115 and 101 persons with or without handsets were selected. The subjects were investigated by questionnaire on their general health, lifestyle, habit, mental stress, the frequency of using the handsets, living and working environment, the cases of suffered from diseases and symptoms of neurasthenia. The data were analyzed by Chi-square test and Logistic regression statistics. The results showed that the time of using handset was positively associated with depression (P < 0.05), nausea (P < 0.01) and loss of appetite(P < 0.05). The results showed that long time use of cellular telephone handset could induce the symptoms of neurasthenia.

Main findings

In questionnaire-based analyses (Chi-square and logistic regression), time of using a cellular telephone handset was positively associated with depression (P<0.05), nausea (P<0.01), and loss of appetite (P<0.05). The authors conclude that long-time handset use could induce symptoms of neurasthenia.

Outcomes measured

• Symptoms of neurasthenia
• Depression
• Nausea
• Loss of appetite

Limitations

• Exposure assessment based on self-reported handset use time
• Outcomes assessed by questionnaire/self-report
• Cross-sectional design limits causal inference
• Potential confounding despite mention of lifestyle, stress, and environment variables

Suggested hubs

• mobile-phones (0.9)
