Promoting changes in diet and physical activity in breast and colorectal cancer screening settings- an unexplored opportunity for endorsing healthy behaviours
Cet article passe en revue les études concernant l'efficacité de programmes d'interventions promouvant, lors des examens de détection d'un cancer du sein ou d'un cancer colorectal, un changement du régime alimentaire et une augmentation de l'activité physique
The importance of diet, physical activity and weight management in breast and colorectal cancer prevention is widely recognised. Whilst there may be many "teachable moments" that could be used to assess and initiate changes in these behaviours by health professionals (to complement public health campaigns) there is little evidence that lifestyle is discussed within cancer screening settings. The lack of advocacy about lifestyle in these settings may endorse poor health behaviours, in particular the absence of guidance to visibly obese patients. To fully utilise the teachable moment, patients need to be aware of the relationship between diet and physical activity and the risk of cancer and to be able to relate guidance to personal behaviours. Results from cardio-vascular and diabetes prevention programmes provide evidence about the components of effective behaviour change programmes which could be used in the screening setting. Findings from interventions initiated in the colorectal cancer screening setting suggest that such programmes can be delivered but it is not clear how acceptable these are in routine health services. Effective Interventions delivered in this setting also offer an important opportunity to contribute to the reduction of the overall burden of chronic non-communicable diseases.
