Fenland Study Phase 3 (Fenland 3) was completed in June 2025.
All participants from Phase 1 of the Fenland Study who agreed to be re-approached for future research were eligible for Fenland 3.
For Fenland 3 we introduced a bespoke Fenland Study app. Participants with compatible devices used the app to complete questionnaires and some measurements digitally at their own convenience in their own homes before the clinic visit. The app also allowed participants to get detailed feedback on their own results direct to their phone, as well as keep up with the latest news from the study.
Alternatively, participants completed questionnaires at home using our online forms. If this was not possible, the option of completing questionnaires during the clinic visit was available.
Participants were invited to attend a clinic visit at one of our three testing facilities in Cambridgeshire. This visit included collection of blood and urine samples, an oral glucose tolerance test, height, weight, hip & waist measurements, a blood pressure reading, an ECG (electrocardiogram), body fat distribution measurement using ultrasound and Dual Energy X-ray Absorptiometry (DEXA), and a fitness test.
Participants were asked to wear a wrist-worn activity monitor to measure their activity during their everyday life for 7 days prior to the clinic appointment.
