Participatory development of the food literacy intervention “GUSTO” for older adults in Germany

Abstract

Abstract Background Healthy aging is one of the major challenges currently faced by an aging population. Food literacy (FL) refers to the ability to apply knowledge and practical skills regarding healthy and sustainable nutrition into everyday life. The project “GUSTO” is sponsored by the Bavarian State Ministry of Health and Care and aims to contribute to enjoyable aging by developing the nutritional skills of people aged 65 and over. This community-based program comprises independent working groups of older adults guided by peer moderators. The FL intervention is developed in cooperation with the target group. Methods The nutritional situation of older adults was first established through a literature research. The results of this research were compared to the “self-perceived food literacy scale” by Poelman et al. (2018) and the “nutritional framework for literacy courses” by Johannsen et al. (2019). The resulting data provided a basis for focus group discussions carried out in six municipalities, supported by local practice partners. In six guided focus group discussions, a number of recurring themes were identified and summarized. Results The focus groups consisted of a total of 44 people between 62 and 88 years of age (average age: 73.1 ± 6.1 years). 22.7 % were men. The group discussions revealed resources used and barriers encountered in terms of FL and interests of older adults. It was evident that, due to the high density of information available, the participants found it difficult to identify reliable information and to implement it in their everyday life. At the request of the focus groups, topics such as the best before date and the use of food waste were added to the intervention. Conclusions Older adults find it challenging to identify reliable nutritional information and implement it in their everyday life. With the help of the participatory approach outlined in this study, target group-related issues can be identified and taken into account in the intervention. Key messages Older adults can be involved in the development of an FL intervention. A participatory approach allows target group-related issues and specific needs to be taken into account in the intervention.
