The Health and Employment After Fifty (HEAF) study recruited 8000 adults aged 50–64 years from 24 British general practices contributing to the Clinical Practice Research Datalink (CPRD). Participants completed a questionnaire about their work and home circumstances at baseline, and were regularly followed-up, initially for a 5-year period. With permission, primary care health records via the CPRD were also accessed. The inter-relation of changes in employment (with reasons) and changes in health (e.g., major new illnesses, new treatments, mortality) will be examined. Findings will inform government policy and also the design of work for older people and the measures needed to support employment in later life, especially for those with health limitations.
