Improving Nutrition and Physical Activity in the Elderly Living at Home - ALAPAGE Study

CONTEXT Promoting healthy aging and preventing loss of autonomy are critical issues for many countries. In France, the 2018-2022 national health strategy emphasizes that adequate nutrition and regular physical activity are key elements of healthy aging. Numerous prevention interventions to improve diet and physical activity in older adults exist in France and abroad, but very few have been evaluated. The ALAPAGE1 prefiguration study revealed a large number of preventive nutrition activities for seniors in Southeastern France, mainly as group prevention workshops. This study showed the need to i) improve the participation of socially isolated and/or economically vulnerable seniors in these workshops to avoid increasing social inequalities in health; ii) improve the form and content of the workshops and harmonize practices; and iii) evaluate the impact of these workshops. A strong partnership dynamic between our research teams and key players in the field of nutrition prevention for seniors has been initiated. It has enabled the co-construction of ALAPAGE project. OBJECTIVES The main objective is to assess the impact of an improved prevention offer, the ALAPAGE group workshops, on the eating behaviors and physical activity of seniors living at home. The secondary objectives are as follows: * To assess the impact of seniors participation in the workshop on their feelings of loneliness and on their quality of life; * To assess the mechanisms by which participation in a group workshop on diet and physical activity improves dietary diversity, physical ability and quality of life of participants, the acceptability of this workshop, the levers they activate and the psychosocial determinants of behaviour (intention, attitude, subjective norms, perceived control). METHODS ALAPAGE workshops will be set up in local structures that usually receive elderly subjects for this type of activity. These workshops will be led by dieticians and professionals in adapted physical activ
