  1. a Data on age, exact BMI, gender and ethnicity was not provided by all studies.
  2. b This is the range for both the self-efficacy and physical activity studies.
  3. c This data is for the statistical analyses conducted, some of the studies were RCT’s but were analysed as pre-post studies.
  4. d One study measured perceived behavioural control, not self-efficacy [68].
