Scientific title

BeWEL: a two-arm multicentre randomised controlled trial of a multiple contact personalised intervention programme versus usual care on weight loss



Study hypothesis

To evaluate the impact of a an intervention programme ("BeWEL") on body weight change, cardiovascular risk factors, diet and physical activity in healthy individuals attending routine NHS clinics who have had pre-cancerous bowel polyps removed but are at risk of developing future cancer and other obesity related conditions.

Colorectal cancer and cardiovascular disease


Intervention group (IG):
Receives the "BeWEL" personalised intervention programme, personal body weight scales and invitations to undertake supervised monthly body weight recordings. The BeWEL personalised, multiple contact, intervention programme will include:
1. Goal-setting for weight, activity, and calorie intake
2. Self-monitoring to achieve these goals
3. Frequent contact to provide accountability and sustain focus
4. Use of problem-solving and other "toolbox" strategies to address goals and potential barriers to achieving them
5. Emphasis on managing individual high-risk situations
The approach will take particular care to emphasise the importance of regular self weighing which is widely associated with greater weight loss and weight prevention (showing a 1 to 3 BMI unit advantage over individuals who do not self weight frequently).

Comparison group (UC):
The usual care (UC) group will be given a general leaflet on healthy lifestyle which is widely available in the NHS setting. This will ensure that all participants receive some lifestyle advice which at the moment is given out on an ad hoc basis.

The total duration of treatment and follow-up is 12 months. Participants will be followed up at 3 months and 12 months post-baseline, and will receive the BeWEL intervention (or usual care) throughout the whole 12 months.
