  1. Odds ratio (OR) with 95% confidence interval (CI) in bold indicates a significant difference in the likelihood of a variable from the group of poor/fair self-rated health (SRH) as the reference category. All variables were entered in one block. Caregiver physical function and caregiving-specific stress total are expressed for half a standard deviation increase in the averaged z-score computed from the five, respectively four, original variables included in these scores
  2. Range of scores: 0 to 6 for physical activity and for alcohol consumption, 0 to 8 for physical health problems, −5.54 to 2.12 for caregiver physical function, 10 to 40 for negative affect, 10 to 50 for positive affect, 1 to 24 for social support, −4.54 to 5.58 for caregiving-specific stress total
