p-values are for comparisons between the analytical and excluded samples. 133 (weighted = 141) participants were excluded due to reporting ‘don’t know’ or ‘prefer not to say’ to the height or weight questions at the baseline or 6-months follow-up surveys. Bold indicates statistical significance. SD: Standard Deviation.
