  1. aAdjusted for age (as a continuous variable), sex (for men and women combined only), alcohol consumption, smoking status, education level, body mass index (as a continuous variable), physical activity (as a continuous variable), psychological stress, sleeping hours (as a continuous variable), medical history, energy intake (as a continuous variable), and SRH at baseline
  2. bThe “Rather poor” and “Pretty poor” categories were combined into a “Poor” group because of the small number of those who responded “Pretty poor” at second survey (n = 14)
  3. hsCRP high-sensitivity C-reactive protein, SD standard deviation, SE standard error, SRH self-rated health
