BeWel: the impact of a body-weight and physical activity intervention on adults at risk of developing colorectal adenomas

For interventions that require individual behaviour change to be successful, it is particularly important to consider the costs and benefits from the perspective of individual participants and their families. These were explored in the context of the CCA and in more depth in the post-intervention interviews. CCA also allows for a very flexible presentation of results in contexts where more than one outcome is of interest.

Outcome and Translation

The intervention produced a significant weight loss for the intervention group. The intervention costs were relatively high as it was delivered in participants’ own homes but this reduced the burden on them. Longer-term outcomes will require further follow up.
