Variables

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 NameExpansionQuestion Text / Variable Label
DiaEvDiabetes EverHave you ever had diabetes?
FeelNervLM Feel Nervous Last month During the last month, have you suffered from nervousness (felt irritable, anxious, tense or restless)?
BPDias1Blood Pressure Diastolic 1Diastolic 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 NameExpansionStudy Part Description
NT3BLQ1HUNT3 Baseline Questionnaire 1HUNT3 survey main questionnaire
NT2DiaQ HUNT2 Diabetes Questionnaire HUNT2 supplementary questionnaire for diabetics
YH1LuIYoung-HUNT1 Lung InterviewYoung-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.

Memory (Hukommelse) is primary category, all other variables in study part are secondary categories (SC). CDR Score=Memory (M) if at least three SC have the same score as M. If three or more SC have higher or lower score than M, CDR score=Majority of SC, regardless whether SC are hihger or lower than M. If three SC one one side of M, and two on the other; CDR Score=M.

CDR

Name:
Clinical Dementia Rating
Description:
The CDR is a 5-item scale used to characterize six domains of cognitive and functional performance applicable to Alzheimer disease and related dementias. The six domains are Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, and Personal Care. The scoring is based on all available information about the patient. An overall CDR score is calculated through the use of an algorithm giving precedence to Memory. A score of 0 indicates no dementia, a score of 0,5 indicates possible dementia, whereas the scores 1, 2 and 3 indicate mild, moderate and severe dementia, respectively. (Hughes et al., 1982)
