Examples of Final Common Data Elements Examined in Center Grant by Concept and Measure

Concept Measure (s) Variables Constituting Common Data Elements
Demographic Characteristics of Sample Demographic Questionnaire Age, race, ethnicity, marital status, education, insurance, income, work status, job type
Rurality

  • Montana State University Rurality Index

  • Rural & Urban Commuting Area Codes (RUCA; determined from zip code)

  • Population of the county of residence from census

  • Distance to emergency care

  • RUCA Code
Quality of Life EQ-5D: Euroqol Quality of Life Scale

  • Includes 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.

  • Health status measured on 100 mm visual analogue scale (endpoints are labeled ‘Best imaginable health state’ and ‘Worst imaginable health state’)
Physical Activity (Self-Report) Behavioral Risk Factor Surveillance System

  • Product of the duration and frequency of each activity level (hrs/wk)

  • Weighted by a standard estimate of the MET level for each activity intensity level (i.e., moderate-intensity = 4 METS and vigorous-intensity = 7 METS)

  • Summed across each intensity level (METs/hrs/wk)
Physical Activity (Objective Measure) (PA) Actigraph Accelerometer (Model GT3X)

  • PA Count average, ct/min/d

  • Count total, ct/d

  • Inactivity (0–99 cts), min/d

  • Light intensity PA (100–759 cts), min/d

  • Moderate-Lifestyle Intensity PA (760–1951 cts), min/d

  • Moderate-Walk Intensity PA (1952–5724 cts), min/d

  • Vigorous Intensity PA (>=5725 cts), min/d

  • Lifestyle moderate vigorous physical activity [MVPA] (>=760 cts), min/d

  • Walk MVPA (>=1952 cts), min/d

METs = Metabolic equivalents is a physiological measure expressing the energy cost of physical activities
