thumb COSMOS is a cohort study of mobile phone use and health. The study will investigate the possible health effects of long term use of mobile phones and other wireless technologies. It is an international study being conducted in five European countries – UK, Denmark, Sweden, Finland, the Netherlands and France. In the UK Imperial College London is carrying out this research. ==Survey design and data collection== The UK study will follow the health of approximately 90,000–100,000 volunteer mobile phone users (18+ years of age for 20–30 years). The international cohort will follow the health of approximately 250,000 European mobile phone users. During a study pre-test in 2009 and the study main launch in 2010, prospective participants were randomly selected by their mobile phone network operator to be invited to participate. In order to maintain confidentiality the COSMOS team had no access to the personal details of those invited to participate in the study until they had given their consent. Participants are asked to fill in an online questionnaire about their health, lifestyle and use of technology. Participants are also asked to give permission for the study to access their NHS and mobile phone records. Participants are contacted approximately once a year in order to update their details or to request additional information. The long term intention of the study is to follow participant’s health status for at least 20 years. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「COSMOS cohort study」の詳細全文を読む スポンサード リンク
