Background: The role of diet in developing psychological disorders has been considered by researchers in recent years.
Objective: To examine the association between major dietary patterns and severe mental disorders in a large sample of adults living in Yazd city, central Iran.
Methods: This cross-sectional study used the baseline data of a population-based cohort study (Yazd Health study: YaHS). Dietary intakes were assessed by a multiple-choice semi-quantitative food frequency questionnaire (FFQ) in the Yazd Nutrition survey (TAMYZ). Psychological assessments were also done by using depression, anxiety, and stress scale-21 (DASS-21) questionnaire. Major dietary patterns were identified using principal component analysis (PCA). Multivariate linear and logistic regression analyses were used to evaluate the relationship between dietary patterns' scores and mental disorders.
Results: A total of 7574 participants were included in the current analysis. Four major dietary patterns were identified: "Sugar and Fats”, “Red meat and Fish”, "Fruits" and “Vegetables”. After adjustment for all confounding variables, participants in the fifth quintile of “Fruits” dietary pattern which was correlated with dried fruits, canned fruits, fruit juice, olive, hydrogenated fats and fruits had a lower odds of severe depression (OR: 0.61, 95% CI: 0.45–0.81, P trend=0.008), anxiety (OR: 0.64, 95% CI: 0.50–0.80, P trend=0.001), and stress, (OR: 0.45, 95% CI: 0.30–0.68, P trend=0.001).
Conclusions: The intake of a dietary pattern high in dried fruits, canned fruits, fruit juice, olive, hydrogenated fats and fruits might be inversely associated with depression, anxiety and stress. Future prospective studies are needed to warrant this finding.
