Oncogeriatric: a collaboration between oncologists and geriatricians which aims to ensure that all elderly cancer patients receive treatment adapted to their condition, thanks to a multidisciplinary and multi-professional approach.
This project aims to gain a better understanding of the motivational determinants of PA and nutrition in elderly cancer patients.
It has a dual objective:
1. to identify clusters/groups in patients on the basis of daily motivational factors focusing on PA and nutrition 2. on the basis of the results obtained in (1), to propose an interventional study based on the previously established clusters, in order to examine the effects of a behavioral intervention on patients' adherence to PA and nutrition, both agreed according to an individualized goal and defined in agreement with the patient and the multidisciplinary team, taking into account the recommendations.
Patient aged 70 or over
With cancer (solid tumors, all sites)
G8 ≤ 14
Inactive (patient not meeting recommended physical activity levels of 150 minutes per week at moderate intensity)
Known presence of brain metastases
Inability to participate in digital platform assessments or physical tests
Inability to eat orally
Contraindication or inability to engage in physical activity
Single group
Collecting the variables and Implementation of a behavioural intervention
BehavioralThe observational phase (during 15 days) * Two measurements per day for motivational variables and physical activity and nutrition * Two measurements per day for nutrition * Three measurements per day for fatigue * Continuous PA measurement by accelerometer The interventional phase : Part A (during 7 days) * measuring physical activity (PA) * complete questionnaires and numerical scales : * Motivational factors * Self-evaluation of nutrition * Self-assessment of fatigue Part B: BEHAVIORAL INTERVENTION (10 weeks),the APA teacher will call a patient once a week for follow-up. Answer questionnaires and scales on the digital platform will be done : * Motivational factors * Self-evaluation of nutrition * Self-assessment of fatigue Part C : End of interventional phase(during 7 days) * measuring physical activity * complete questionnaires and numerical scales : * Motivational factors * Self-evaluation of nutrition * Self-assessment of fatigue
For observationnal phase : Identify relevant motivational levers in order to build a personalized and adapted behavioral intervention to improve physical activity and nutrition behaviors, via cluster analysis.
Clusters (groups of patients) evaluated by the "silhouette coefficient" and seprated by behavior, on one hand concerning Physical Activity (PA) and on the other hand concerning nutrition.
For Interventionnal phase : Improving nutrition behaviors of elderly cancer patients
