  1. The Nord-Trøndelag Health Study 1995–97, women and men >24 years.
  2. a Scaled from 0–100 where 100 represent the worst health score.
  3. b The within couple coefficient gives the expected change in health score for one-year education change in the difference between the individual education and the couple average education, holding the latter constant.
  4. c The between couple coefficient gives the expected change in health score for one-year education change in the couple average education, while holding the individual deviation from the average constant.
  5. d Couple level variance divided by the total variance, multiplied by 100.
