Tiivistelmä
TamPubissa tutkielman rajattu versio. Täydellinen versio luettavissa Tampereen yliopiston Linna-kirjastossa.
The PDF is a limited version of the Master's thesis. The complete text is available in printed version in University of Tampere Linna library.
Background: The number of mobile phone users has grown explosively, which has generated mounting public concern regarding possible health hazards. This study aims to assess pituitary tumor risk as it has rarely been investigated.
Materials and Methods: A case-control study was conducted with eligible cases identified from all five university hospitals in Finland and frequency-matched controls from national population register. Controls were matched to cases by age, sex, region of residence and date of interview. A detailed history of mobile phone use was obtained by a structured interview. Several indicators of mobile phone use were assessed using conditional logistic regression.
Results: A reduced odd ratio was seen among regular mobile phone users (OR 0.39, 95% confidence interval, CI: 0.21, 0.72) relative to never/non-regular users, possibly reflecting methodological limitations. Pituitary tumor risk was not increased after 10 or more years since first use (OR 0.69, 95% confidence interval, CI: 0.25, 1.89).The risk was not increased in relation to duration or, cumulative hours of use or cumulative number of calls. The results were similar for analogue and digital phones.
