During 2017 and 2018 we asked participants to complete our first follow-up questionnaire to find out how their mobile phone use, health and lifestyle had changed since they joined the COSMOS study. The online follow-up questionnaire is now closed and we would like to thank everyone who filled it in.
The team have produced a new paper reporting on the most important part of the study: Our participants. Published in November 2015, the paper explores the formation and make-up of the cohort in detail, including statistics on location, gender, ethnicity, obesity, health and well-being and mobile phone usage. The paper describes the study’s aims and research methods, including the scope of the data collected and the importance of data linkage to routine health registry records and network operator mobile phone use data.
For an in-depth look at the cohort, the paper is available here: ‘Cohort profile: ‘Cohort profile: UK COSMOS—a UK cohort for study of environment and health’
