The primary purpose of the protocol is to evaluate the feasibility and acceptability of a home-based (using information and communication technologies) intervention composed of nutritional counselling, exercise and cognitive training in older adults and its potential effect on various health outcomes.
Nutritional interventions, physical exercise and cognitive training have been used to delay cognitive decline during aging, with mixed results being obtained. However, few studies have investigated the health benefits of combining two or more of those interventions (ie, the so-called multidomain approach) in older adults. Intensive in-person multidomain intervention may difficultly be translated into the "real world" of healthcare systems because currently unpractical. Therefore, (cost-)effective interventions provided at distance and without the physical presence of healthcare professionals have the potential to be better translatable from research to real life. Information and Communications Technologies (ICT) have a crucial role to play in this context. However, to the best of our knowledge, no studies have investigated the effects of an ICT multidomain intervention on cognition in the elderly yet. Thus, the main objective of eMIND is to test the feasibility and acceptability of a 6-month, home-based multidomain intervention composed of nutritional counselling, exercise, and cognitive training provided using ICT solutions in people aged 65 or over. Secondary objectives include to obtaining preliminary data on the effects of the intervention on clinical outcomes in order to inform the design and sample size calculations of a future trial. eMIND has a mixed design, being composed of a randomized controlled trial (RCT, with two groups: the ICT multidomain intervention group vs Control Group) and a qualitative study (semi-structured interview to assess the easiness-of-use of the website).

Intervention composed of cognitive training (reasoning and memory training), nutritional counselling (advices to raise awareness about the importance of promoting a diversified and balanced diet), and physical exercises (program and monitoring of progression). The access of control group to the website will be limited to general information about eMIND study and links to the website of health authorities regarding to the healthy ageing topics.

Compliance to the protocol
Compliance to measure the feasibility of the study: Participants will be asked to connect the physical exercise interface at least twice a week, the cognitive stimulation interface at least twice a week, and the nutritional interface at least once each 15 days. Participants who adhere to \>75% of this frequency of web-site use will be considered adheres (quantitative approach)

Physical activity Monitoring
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Physical data will automatically be transferred from the wrist-worn activity monitors (Fitbit Flex 2) to the application and will generate data regarding participant's number of steps walked, energy expenditure, and walking speed, in a weekly basis
Time frame: Assessment of these measures at the end of the intervention: 6 months after the inclusion
Short Physical Performance Battery
Physical function will be evaluated by the validated short performance battery SPPB, which is based on three physical tests: timed short distance walk (4 meters at usual pace), timed repeated chair stands (5-repetition chair rise), and timed balance tests (standing balance) (20). Each of these tests is assigned a score ranging from 0 to 4, with 4 indicating the highest level of performance and 0 the inability to complete the test. A summary score ranging from 0 (worst performers) to 12 (best performers) is calculated by adding walking speed, chair stands and balance scores. From the timed short distance walk test we will calculate participants' walking speed in meters/sec; therefore, although walking speed composes the SPPB overall score, it will also be analyzed separately.

Mini-Nutritional Assessment (MNA)
This questionnaire is composed of 18 items aiming at classifying older adults as normally nourished (24≤score≤30), at risk of malnutrition (17≤score≤23.5) or malnourished (score\<17).
Time frame: Assessment of these measures at the end of the intervention: 6 months after the inclusion
Health-related quality of life and Health economic Euro-QoL 5D-3L
The health-related quality of life will be assessed by the Euro-QoL 5D-3L, a valid and short questionnaire including five questions on mobility, autonomy, daily activities, pain and depression.
