Application for Mobile Devices to Measure Daily Protein Intake in the Elderly: PROT + First Results

Among the various domains of a Comprehensive Geriatric Assessment, nutritional assessment stands out for its important relationships with major geriatric syndromes, such as frailty syndrome and sarcopenia. In this context, the development of an application to assess the daily protein intake facilitates the identification of low protein intake and the nutritional risk of this user. In this work, we developed and evaluated the usability of a protein intake control application to be used by the elderly. The application was developed targeting the population of users over 60 years old, regardless of schooling, in the presence or absence of dementia. System Usability Scale (SUS) was used for usability evaluation with the users (n = 18). The PROT + offers an easy use mobile application for elderly, helping the users and their families to access an evaluation based on household measures to control their protein intake daily. There were significant differences for usability between the 60–69 and 70–79 age groups.
