Caruso, Rosa Reddavide, Maria Notarnicola, Stefania Maggi, Ai Koyanagi, Michele Fornaro, Joseph Firth, Lee Smith, Marco SolmiFew studies assessed associations between dietary vitamin K and depressive symptoms. We aimed to investigate the association between dietary vitamin K and depressive symptoms in a large cohort of North American People. In this cross-sectional analysis, 4,375 participants aged 45-79 years from the Osteoarthritis Initiative were included. Dietary vitamin K intake was collected through a semi-quantitative food frequency questionnaire and categorized in quartiles. Depressive symptoms were diagnosed using the 20-item Center for Epidemiologic Studies-Depression (CES-D) > 16. To investigate associations between vitamin K intake and depressive symptoms, logistic regression analysis were run, adjusting for potential confounders. Overall 437 (=10%) subjects had depressive symptoms. After adjusting for 11 confounders, people with the highest dietary vitamin K intake had lower odds of having depressive symptoms (OR=0.58; 95%CI: 0.43-0.80). This effect was present only in people not taking vitamin D supplementation. In conclusion, higher dietary vitamin K intake was significantly associated with a lower presence of depressive symptoms, also after accounting for potential confounders. Future longitudinal research is required to explore the directionality of the association.
