Organisation and quality assurance of the HUNT data is managed by Arnulf Langhammer and the Databank staff.
HUNT Databank database software development by Jon Heggland.
Each HUNT variable has a unique name, consisting of two parts separated by @. The first part is called the Topic Name, and indicates what the variable measures or asks about. The second part is called the Study Part Name, and indicates the source of the variable. Both parts are constructed by concatenation of suitable abbreviations selected from a list developed and maintained by HUNT Research Centre.
The Topic Name aims to paraphrase the question text or describe the measurement of the variable in a succinct way. Examples:
Topic Name | Expansion | Question Text / Variable Label |
---|---|---|
DiaEv | Diabetes Ever | Have you ever had diabetes? |
FeelNervLM | Feel Nervous Last month | During the last month, have you suffered from nervousness (felt irritable, anxious, tense or restless)? |
BPDias1 | Blood Pressure Diastolic 1 | Diastolic blood pressure, measurement 1 |
The Study Part Name identifies the Study Part the variable belongs to. A Study Part is a collection of questions, measurements or analyses managed as a unit, e.g. in the form of a questionnaire or interview. The first abbreviation of a Study Part Name indicates which main survey it belongs to: NT1, NT2, NT3, NT4 (for HUNT1-4), YH1, YH2, YH3, YH4 (for the Young-HUNT studies) or others. Other important, frequently occurring abbreviations are Q (Questionnaire), I (Interview), M (Measurements), and BL (Baseline, indicating the common survey packages that the Nord-Trøndelag inhabitants were invited to). Examples:
Study Part Name | Expansion | Study Part Description |
---|---|---|
NT3BLQ1 | HUNT3 Baseline Questionnaire 1 | HUNT3 survey main questionnaire |
NT2DiaQ | HUNT2 Diabetes Questionnaire | HUNT2 supplementary questionnaire for diabetics |
YH1LuI | Young-HUNT1 Lung Interview | Young-HUNT1 Lung study interview |
Identical or very similar questions/measurements frequently occur in multiple Study Parts, and in such cases the Topic Name is the same. Thus, AstEv@NT2BLQ1 and AstEv@NT3Lu1I both ask if the participant has or has ever had asthma, but the former in the baseline questionnaire of HUNT2, and the latter in the interview of phase 1 of the HUNT3 Lung Study.
