An extensive low-responder analysis is actually finished just after HUNT1

one in HUNT2, immediately after finishing this new fieldwork, a 2.5% haphazard take to regarding low-attendants try chose (n = 685) having a non-contribution analysis. 2 These studies indicated that area of the things about non-attendance for all those aged 20–49 many years try diminished some time and becoming away from condition. About age group 45–69, an element of the causes was indeed getting very busy, forgetting the brand new invitation or otherwise not being curious. For people aged 70+, the main reasons was indeed having normal follow-right up regarding the wellness services or being immobilized due to state. To your HUNT3 Survey, additional non-participation analyses were accomplished. These will soon be presented when you look at the an article in preparation (A good Langhammer, private correspondence, ). An assessment anywhere between people answering Q1 and you can respondents merely responding good non-contribution questionnaire shared with all the non-participants, an evaluation between players and you may low-members within the national files and you can a comparison out of respondents having analysis regarding at random chose standard practices. The brand new analyses indicated that among non-professionals, the newest prevalences out-of CVDs, all forms of diabetes mellitus and you may psychiatric problems were high in both low-fellow member investigation and you will investigation taken from standard routine, compared to one claimed by the players. With respect to the sign in data, the new non-people had lower socio-monetary status and you can a higher mortality than people. Ergo, with regards to the concern less than search, possible alternatives bias can be considered.

Surveys into the HUNT3 ( Table cuatro)

Q1 are a personal-report questionnaire occupied in home till the participants attended new earliest fitness examination. Pursuing the medical examination, one minute questionnaire (Q2) that have a common big region and a certain sex and years (20–29, 30–69, 70+ years) region was handed out over individuals. Further, a third category of questionnaires (Q3) gotten to people that have chosen illness or any other sandwich-organizations according to kind of solutions given inside Q1 ( Dining table 4). As much as three different Q3s have been given out every single new member. Q2 and you can Q3 would be to become completed home and you may returned from the send for the a pre-paid off package. On 80% of one’s people came back Q2/Q3. These types of forms provided questions relating to socio-economic climates, health-related habits, periods, conditions and infection.

b No new member try questioned so you can fill out more around three other Q3s. Top priority was given in order to Q3s for all forms of diabetes, CVD and you can cancers; for this reason several players with many disease have been omitted throughout the almost every other Q3s.

b No participant is actually requested in order to complete over three different Q3s. Priority obtained so you’re able to Q3s to have diabetes, CVD and you will disease; ergo a number of players with quite a few disease have been omitted on almost every other Q3s.


Most of the people answered an interview on health examination web sites. Functioning citizens were required work-related headings, business sectors and you may exposures to work-related problems. Concurrently, lady were questioned from the intervals, pregnancies and you can breastfeeding.

Scientific proportions

Blood pressure level and you will heartrate was basically measured having fun with an effective Dinamap 845XT (Critikon) based on oscillometry. 19 Top and you can weight were measured on the members wearing white clothing versus sneakers: peak for the nearest centimetre and you can weight into the nearby 50 % of kg. Waist and stylish circumferences was basically mentioned that have a ring to the nearest centimetre, toward fellow member updates along with the arms dangling casual. The new hips circumference was counted horizontally in the height of your umbilicus, and also the hip circumference is actually measured simultaneously in the thickest region of your stylish.

Bloodstream and you will urine testing, biobanking

Biological topic try collected at the health test stations and transported day-after-day by the courier with the biobank. Blood testing accompanied a rigorous high quality method, meeting serum, plasma, buffy coat, immortalized muscle to have mobile range production, certified tubes to have trace metal/factors study and you will RNA tubes. Pee is collected preferably, and you can frozen immediately. Actions have been founded to possess (i) bloodstream fractionation and you will shipping for the dos-D club coded cryo tubes, (ii) DNA isolation and you will normalization and you may (iii) shops and you will retrieval of just one billion DNA samples functioning during the ?20°C. Products also are kept at the ?80°C when you look at the manual super-freezers along with brand new vapour phase away from liquids nitrogen. Information could be discussed during the a unique report (K Hveem, individual telecommunications, ).
