Study Type Epidemiology
Model Mobile phone use and analysis of recall bias in epidemiologic study exposure assessment questionnaires

Volunteer mobile phone users (n=138) from the Leeds area, aged 15 to 68 years, were recruited to provide estimations of mobile phone use (via questionnaire) that were subsequently compared with actual phone records from their network operator data. A consistent pattern of systematic bias for over-reporting the number (on average ~70%) and duration (on average ~280%) of calls was observed. The authors conclude "self-reported mobile phone use may not fully represent patterns of actual use". Performed as part of the University of Leeds INTERPHONE study arm (#317).

    This study does not even take into account the wide variation of RF exposure by other factors including the nature of the network, dynamic power control, position of the phone, physical dimensions of the user, hands-free kit use, etc.
