  1. † Adjusted for age, sex, and NZDep score.
  2. ‡ Often/always combined due to low numbers reporting “always”.
  3. Odds ratios are for the number of behaviours participants rated they had changed “Somewhat” or “Very much so” compared to “Not at all” or “A little”. CRC = colorectal cancer; GAD-7 = Generalized Anxiety Disorder scale – 7.
