ABSTRACT

Background:

Demographic change is leading to an increasing proportion of older people in the German population and requires new approaches for prevention and rehabilitation to promote independence and health of the older people. Technical assistance systems can offer a promising solution for the early detection of nutritional and physical deficits and the initiation of appropriate interventions.

Objective:

This study aims to identify the requirements of the target group. The overall project will develop a measurement and training station (MuTs) to be used independently by participants aged ≥ 70 years to assess and improve their nutritional status and mobility.

Methods:

Older adults were recruited from a community-based setting as well as from a geriatric rehabilitation centre. Focus group interviews were conducted between August - November 2022. Following a semi-structured interview guideline attitudes, requirements, preferences and barriers for the MuTs were discussed. Discussions were stimulated by videos, demonstrations of measuring devices and participants' ratings of the content presented using rankings. After one focus group in the rehabilitation center and two in the community were conducted, the interview guide was refined making a more detailed discussion of identified elements and aspects possible. The interviews were recorded, transcribed verbatim and analysed using content analysis by Kuckartz.

Results:

A total of 21 older adults (n=11 female (52%), mean age 78.5 ± 4.6 years) participated in five focus group discussions. There was a strong interest in the independent measurement of health parameters such as pulse and hand strength, especially among people with health problems who would welcome feedback on their health development. Participants emphasised the importance of personal guidance and interaction before using the device, as well as the need for feedback mechanisms and personalised training for everyday use. Balance and coordination were mentioned as preferred training areas in a MuTs. New training options that motivate and invite people to participate could increase the willingness to use the MuTs.

Conclusions:

The target group is generally open and interested in tracking and optimising diet and physical activity. A general willingness to use a MuTs independently was identified, as well as a compelling need for guidance and feedback on measurement and training to be part of the station.
