Feasibility Study to Assess the Impact of a Lifestyle Intervention during Colorectal Cancer Screening in France

Current evidence suggests that 30–50% of cancers are attributable to established lifestyle risk factors. Cancer-screening has been identified as an opportunity for delivering advice on lifestyle behaviour change for cancer prevention. This study aimed to evaluate the feasibility and acceptance of promoting advice on the latest evidence-based lifestyle recommendations for cancer prevention at the time of colorectal cancer screening at two hospitals in Lyon, France. This feasibility study included 49 patients (20 men and 29 women) who were invited for colonoscopy. Patients received a leaflet with lifestyle recommendations for cancer prevention, accompanied with a logbook to plan and monitor their behavioural changes. Feedback from patients, hospital staff, and researchers was received via evaluation questionnaires (n = 26) completed after testing the educational material for at least two weeks and via two focus group discussions (n = 7 and n = 9 respectively) organized at the end of the study. All interviewed patients were interested in lowering their cancer risk, and the majority felt ready to change their lifestyle (88%), although most did not know how to decrease their risk of cancer (61%). All patients found the educational material easy to understand and sufficiently attractive and 50% of the patients reported having achieved at least one of the healthy behaviours recommended within the two weeks following the intervention. All hospital staff and almost all patients (92%) involved found that the screening program and the visits planned for colonoscopy was an appropriate moment to provide them with the educational material. This feasibility study has shown that the content, paper-based format, and time of delivery of the intervention were adequate. Health professionals seem to be willing to provide lifestyle recommendations, and patients appear interested in receiving advice for lowering their cancer risk during screening visits

SVELTE: Evaluation device of energy expenditure and physical condition for the prevention and treatment of obesity-related diseases through the analysis of a person's physical activities

Le niveau quotidien d’activité physique influence les risques de développement des pathologies chroniques les plus fréquentes. Chez l’adulte, un faible niveau d’activité physique et un comportement sédentaire sont associés à une augmentation des risques de maladies cardio-vasculaires (comme l’hypertension artérielle), de diabète de Type 2 et de certains cancers. L’activité physique intervient également dans le contrôle du poids des personnes obèses, et le maintien de l’autonomie chez la personne âgée. Dans ce contexte, l’objectif du projet SVELTE est de développer un outil innovant d’évaluation des comportements d’activité physique au quotidien et de la condition physique. Dans un premier temps, des prototypes permettant l’enregistrement de signaux de plusieurs capteurs (incluant accéléromètres et magnétomètres triaxiaux….) ont été développés. Ces prototypes ont une autonomie de plusieurs jours (mémoire et énergie), sont non-intrusifs et faciles d’utilisation pour le sujet. Des bases de données annotées ont ensuite été constituées afin de développer les algorithmes permettant : (i) l’évaluation de la condition physique d’un sujet à un instant donné ; (ii) la caractérisation de l’activité physique tout au long de la journée et (iii) l’estimation de la dépense énergétique liée à cette activité physique. Une étude clinique impliquant 120 sujets (obèses et non-obèses) équipés du dispositif de mesure durant deux semaines est en cours et permettra d’évaluer la robustesse et la justesse des algorithmes innovants développés
