Clinical trials

The goal of this randomized, controlled trial is to examine the effectiveness of dietary counseling on depressive symptoms, work ability, and quality of life in mental health and substance abuse professionals. The main questions it aims to answer are: * Whether dietary counseling can lower depressive symptoms and depressive symptoms-related sick leave days and improve work ability among mental health and substance abuse professionals * Whether dietary counseling can improve life quality, diet quality, and eating behavior among mental health and substance abuse professionals. Subjects of the intervention group will participate in five dietary counseling sessions during six months. Participants in the control group do not receive any intervention. Researchers will compare the intervention and control groups to see if dietary counseling is effective in reducing the risk of depressiveness and depression-related sick leave days and improving work ability, quality of life, and nutritional habits.
