The aim of this study is to investigate (1) the user experiences and usability of the nutrition apps (the Finnish Nutrition Navigator and the Finnish Nutrition Path) in occupational health care from the perspective of both professionals and customers, (2) the impact on diet, eating behavior, perceived well-being (perceived state of health, quality of life, work and functional ability) and anthropometric indicators compared to treatment as usual, and (3) cost-effectiveness of using the nutrition apps.
For the occupational healthcare customer, the study will include two visits to the occupational healthcare: at baseline and after a 12-week follow-up. First, all volunteer participants enrolled in the study will belong to the control group and they will get the treatment as usual. Their weight, waist circumference, and blood pressure are measured at the visit and they are asked to answer a digital research questionnaire at both baseline and follow-up.
The rest of the volunteer participants enrolled in the study will belong to the intervention group. Before the visit at the occupational healthcare, they are asked to fill in the Finnish Nutrition Navigator and to read the automated feedback about the diet quality. The Finnish Nutrition Path can help in the dietary goal setting and it can be utilized together with the professional or independently. In addition, also weight, waist circumference, and blood pressure are measured at the visit and the participant is asked to answer a digital research questionnaire. The same procedure is done at both baseline and follow-up.
