At the time of the 3HC, the EPIC-Norfolk participants fell into the 50-92 age group.
It was therefore important to have more information on diseases and health endpoints
of relevance to the older population. We wanted to to see how these may impact
on our daily lives making us more prone to serious illnesses such as cancer, heart
disease and diabetes. Repeat assessments in this phase included a follow-up health
questionnaire, a 7-day food diary and the same physical measures taken at the first
and second health checks: height, weight, hip, waist and chest measurements, blood
pressure, lung capacity, heel-bone ultrasound, percentage body fat and a blood sample.
New assessments in this phase included memory and cognition testing and a thorough
eye examination using some of the latest technology in optic nerve and retinal
photography. We looked in particular at glaucoma and age related macular degeneration,
which are the two major causes of irreversible blindness in this country. The average
3HC appointment lasted 2.5 hours, which is longer than previous health checks and
this was due to this check being far more comprehensive than those carried out previously.
