Nutrition-related lifestyle group sessionsCognitive trainingClinical nutrition consultations
Nutrition-related lifestyle group sessions: In person lifestyle group sessions of 180-minutes per week, directed by a nutritionist, and comprising:
1. nutrition education session for preparing healthy meals, followed by a period of social interaction while consuming the meals prepared. Participants will be encouraged to apply the healthy cooking techniques covered in each session in their home context.
2. daily activities to reduce physical inactivity (e.g., walking to the supermarket to buy ingredients, playing traditional games, caring for community gardening, among others).
Cognitive training: Individualized cognitive training performed remotely, at home on their own. The participants will be invited to perform cognitive training exercises at least twice a week using COGWEB®, an online platform for cognitive training. For those unable to use computer devices, similar exercises will be available in paper-and-pencil format.
Clinical nutrition consultations: A registered nutritionist will conduct individualized clinical nutrition consultations to each participant three times over the course of the study period.
Study summary
This study intends to evaluate the feasibility and the effectiveness of an innovative and integrated nutrition-based intervention addressing key modifiable risk factors for dementia while meeting participants' preferences for nutrition-related sessions. The intervention will include lifestyle group sessions regarding nutrition education and physical activity, individualized cognitive training at home, as well as clinical nutrition consultations.

Primary outcome measure(s)
Self-reported adherence to the Mediterranean Diet — Up to 6 months Variation of participant's self-reported adherence to the Mediterranean diet, assessed using the Mediterranean food pattern scale (MEDAS), between the baseline assessment and the end of the intervention. This scale varies from 0 (lowest adherence to the Mediterranean diet) to 14 points (highest adherence to the Mediterranean diet). A score ≥ 10 points indicates good adherence to the Mediterranean diet.
Self-reported quality of life — Up to 6 months Variation of participant's quality of life, assessed using the EuroQol Group scale - 5 dimensions (EQ-5D) scale, between the baseline assessment and the end of the intervention. This scale is subdivided into two subscales: a) five multiple choice questions, with five response possibilities, which produce a score that varies from 5 (best score) to 25 points (worst score); b) visual analogic scale, that varies from 0 (worst score) to 100 (best score).
