Nutrition Apps in Occupational Healthcare (Pilot Study of the FOODNUTRI Project)

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.

• Utilization of the Finnish Nutrition Navigator and the Finnish Nutrition Path (Other): Participant fills in the food intake questionnaire of the Finnish Nutrition Navigator and receives an automated feedback on the diet before the visit to the occupational healthcare. At the visit, the information about the quality of diet can be utilized with the occupational healthcare professional. The client can utilize the self-care path (the Finnish Nutrition Path) for possible dietary changes independently or with the professional.
