[ENG]Background: The increasing use of smartphones by older adults also increases their potential for improving
different aspects of health in this population. Some studies have shown promising results in the improvement of
cognitive performance through lifestyle modification. All this may have a broad impact on the quality of life and
carrying out daily living activities. The objective of this study is to evaluate the effectiveness of combining the use
of smartphone and smartband technology for 3 months with brief counseling on life habits, as opposed to
providing counseling only, in increasing physical activity and improving adherence to the Mediterranean diet.
Secondary objectives are to assess the effect of the intervention on body composition, quality of life, independence
in daily living activities and cognitive performance.
Methods: This study is a two-arm cluster-randomized trial that will be carried out in urban health centers in Spain.
We will recruit 160 people aged between 65 and 80 without cardiovascular disease or cognitive impairment (score
in the Mini-mental State Examination ≥24). On a visit to their center, intervention group participants will be
instructed to use a smartphone application for a period of 3 months. This application integrates information on
physical activity received from a fitness bracelet and self-reported information on the patient’s daily nutritional
composition. The primary outcome will be the change in the number of steps measured by accelerometer.
Secondary variables will be adherence to the Mediterranean diet, sitting time, body composition, quality of life,
independence in daily living activities and cognitive performance. All variables will be measured at baseline and on
the assessment visit after 3 months. A telephone follow-up will be carried out at 6 months to collect self-reported
data regarding physical activity and adherence to the Mediterranean diet.Discussion: Preventive healthy aging programs should include health education with training in nutrition and
lifestyles, while stressing the importance of and enhancing physical activity; the inclusion of new technologies can
facilitate these goals. The EVIDENT-AGE study will incorporate a simple, accessible intervention with potential
implementation in the care of older adults.
