Assessment of Nutrional Needs, Wishes and Motives of Youths as well as the Development of Games and Recommender Approaches for Supporting Healthier Food Choices

Survey

Quelle: Stobrawe/Kl.r.d.Isar

In preparation for developing a target group-specific digital game platform for nutritional games a survey was conducted. Aim was to gather data about adolescents` and young adults` needs, wishes and motives regarding „nutrition“ and „digital gameplay“.

In total, 339 adolescents of six general secondary schools in the area of Rosenheim were surveyed from june 2016 to june 2017 using a paper questionnaire. In addition, 476 young adults filled in an online questionnaire regarding same subjects. Survey results revealed that adolescents and young adults are interested in digital nutritional information. Furthermore, it could be shown that nutritional knowledge is deficient and has to be improved. Data analysis is ongoing. Results serve as a basis for the development of a digital nutritional games platform.

One of our students, who is involved in the development of the game, has been interviewed by TUMstudinews.
The full interview can be found here: Interview

Adolescents and young adults often change their nutritional habits and are likely to choose food for reasons not related to nutritional needs and health (e.g., peer pressure or social activities). Mal- and overnutrition occur frequently in this age group, leading to an increasing prevalence of overweight and obesity. Reaching this target group is a particular challenge, which requires a large amount of knowledge about their needs, wishes, and motives regarding nutrition. Moreover, scientific knowledge in regard to target group adapted gamification and recommender approaches in the context of imparting of nutritional knowledge is rather limited, especially in Germany. The hypothesis is that adolescents and young adults are mostly reachable by new information and communication technologies (ICT) (e.g. gamification). [1] Ernährungsbericht 2000 der DGE www.dge.de.

Objectives:

  1. Adolescents and young adults will be asked about their needs, wishes and motives related to food decisions. Therefore, direct interviews (qualitative assessment) in focus groups and a questionnaire-based survey (quantitative assessment) will be performed.
  2. A game as well as social recommender approaches related to nutritional items will be developed. Results will identify gaps/tools/channels to improve the imparting of nutritional knowledge.
First prototypes have been developed for the avatar as well as for the backpack-game.
