A thorough non-responder studies is actually completed after HUNT1
1 in HUNT2, just after doing the fieldwork, a 2.5% haphazard decide to try off non-attendants is selected (n = 685) to possess a non-involvement research. dos This research indicated that a portion of the reasons for having non-attendance for people aged 20–44 age try decreased some time getting beyond your county.

For people old 70+, part of the reasons was basically having regular follow-up about wellness functions or being immobilized on account of disease. Towards the HUNT3 Survey, various other low-involvement analyses have been complete. These types of will undoubtedly be presented in the a blog post in preparation (An effective Langhammer, private communication, ).

With respect to the register data, brand new low-users got straight down socio-financial status and you can a top death than just players. For this reason, according to matter less than lookup, you’ll choices prejudice should be considered.
Surveys for the HUNT3 ( Desk 4)
Q1 try a home-statement survey occupied during the at home through to the participants went to the very first health test.

After that, a 3rd group of forms (Q3) was given to prospects with picked sickness and other sandwich-organizations predicated on particular solutions offered in the Q1 ( Dining table 4). As much as three different Q3s had been passed out every single participant. Q2 and you may Q3 were to become completed home and you will returned by the mail into the a good pre-paid off envelope.

Biological topic is collected within fitness examination programs and directed day-after-day by courier towards the biobank.
