Conclusion (acc. to author)
risk of headache was observed in mobile phone users compared with non-users (group 2: OR 1.38, CI 1.18–1.61). Among mobile phone users, the risk of headache was also increased in those who had longer daily call duration compared users with call duration of < 2 min/day (group 4: OR 1.62, CI 1.34–1.98; group 5: OR 2.50, CI 1.76–3.54) and higher daily call frequency compared to < 2 calls/day (group 7: OR 1.37, CI 1.07–1.76; group 8: OR 2.52, CI 1.78–3.58). The authors conclude that mobile phone use is significantly associated with headache. Further epidemiologic and experimental studies are required to affirm and understand this association.
