Abstract
ISEE-0157 Abstract: There is some scientific and public concern that radiofrequency electromagnetic fields may increase risk of disease, especially in children, having thinner skulls, developing/immature brains and long lifespans. Many epidemiological studies have evaluated the relationship between mobile phones and health, particularly brain tumors. As pointed out by both WHO and EU, none of these studies have addressed the effects in children and most have been case-control studies which are by design limited to predefined outcomes and inherently prone to recall bias particularly with extended recall periods. Several studies addressing these deficiencies are in progress. For adults COSMOS, a multinational cohort is being established in Denmark, Finland, Netherlands, Sweden and UK with a size (200.000+) and timeframe (25+ years) allowing detailed analyses even of rare outcomes and special user groups. Repeated questionnaires allow the study to reflect the evolving technology. The first population-based results have been provided by the less detailed cohort of adult Danish subscription holders (420.000) which has been analyzed for cancer and neurodegenerative diseases. For children there now exist two cohort studys: Danish National Birth Cohort; mothers provided data on mobile phone exposure of their children (13.000), during pregnancy and childhood. The cohort has been analyzed for behavioral problems. MoRPhEUS; an Australian study where 300 teenagers have repeatedly provided data on use of mobile phones and been tested for cognitive abilities. Furthermore two case-control studys of brain tumors in children are being setup: CEFALO is a collaboration between Denmark, Sweden, Switzerland, Norway, and the UK (start in 2005. age range: 6–19, expecting 550 cases in total). Exposure is assessed from structured interviews and operator provided records. MobiKids: Similar in design to CEFALO (age range: 10–24. expected cases: 1900, start in 2009, 12 countries).
