The Airwave Health Monitoring Study

About the cohort

Start date: June 2004
Age at recruitment: 17- 80
Sample size at recruitment: 53,280
Estimated current sample size: 53,265

The Airwave Health Monitoring Study was established to evaluate possible health risks associated with the use of TETRA, a digital communication system used by the police forces and other emergency services. It is a long-term observational study following up the health of police officers and staff across Great Britain, with the ability to monitor both cancer and non-cancer health outcomes through data linkage. 53,280 participants have been recruited between June 2004 and March 2015 with a response rate averaging 50% of employees in participating forces. At baseline, participants completed an enrolment questionnaire (sent via routine administration or the occupational health service), or a comprehensive health screening performed locally, or both. Around 85% (N=45,533) of the sample received a health screening. Clinical and biological measurements were taken, blood and urine samples collected. Participants were 40 years old on average, mostly men (63%) and white British (85%). Screened participants have now been followed-up for 7.5 years on average. A second assessment of participants living in England started in November 2015 and is ongoing.
