The cohort divided into low-risk, moderate-risk and high-risk categories, based on their behavioural responses at baseline and at 4-week follow-up. The low-risk category comprises participants not reporting any of the four risky behavioural practices. The moderate-risk category comprises participants reporting either “adding salt at the table” or an unfavourable response to any of the other three behaviour questions. The high-risk category comprises participants who “add salt at the table” and report at least one other unfavourable behavioural response.
