Depression Relationship with Dietary Patterns and Dietary Inflammatory Index in Women: Result from Ravansar Cohort Study.
Ontology highlight
ABSTRACT: Background and aimsChronic inflammation is thought to have a major role in the pathophysiology of depression. Diet has been shown to modulate the inflammatory state, thus emphasizing its potential as a therapeutic role in depression. But, little is known about the relationship between dietary intake and depression. The current study aimed to investigate the relationship between major dietary patterns, a dietary inflammatory index (DII) score, and depression among women.Methods and MaterialsThis cross-sectional study included 4630 women aged 35–65 years using baseline data from the Ravansar Non-Communicable Diseases (RaNCD) cohort study in Western Iran. Diet was evaluated using a validated 125-item food frequency questionnaire (FFQ) to determine DII scores and dietary patterns. Traditional, healthy, and unhealthy dietary patterns were extracted using factor analyses.ResultsA significant upward trend in the odds of depression was observed across the tertiles s of DII scores (P-trend: 0.019). After the adjustment for possible risk factors, a high adherence to an unhealthy dietary pattern was associated with a higher risk of depression than a low adherence (OR: 1.63; 95% CI: 1.1–2.4). A high adherence to a healthy dietary pattern was associated with the lower odds (OR: 0.61; 95% CI: 0.04–0.92). Among the main food groups, a high intake of eggs and refined grains was associated with a higher risk of depression.ConclusionIn women, a refined grain dietary pattern is a risk factor for depression, whereas a healthy dietary pattern is protective. We have also shown that adherence to a pro-inflammatory diet was significantly associated with depression. Adherence to a dietary pattern with high intakes of dairy products, seafood, red meats, nuts, vegetables, fruits, flavor, and vegetable oils and diets with low inflammatory properties were associated with a lower risk of depression in women.
