Association between the Japanese-style diet and low prevalence of depressive symptoms: Japan epidemiology collaboration on occupational health study
This research investigates the relationship between Japanese dietary patterns and depressive symptoms, highlighting the potential mental health benefits of adherence to these diets. Conducted as part of the Japan Epidemiology Collaboration on Occupational Health Study, the survey involved 12,499 participants and utilized a validated food frequency questionnaire to assess dietary intake. The study developed scores for both traditional (9-item) and modified (11-item) Japanese diets. The traditional diet consisted of items such as white rice, miso soup, and green tea, whereas the modified version included whole grains, fruits, and dairy products. Depressive symptoms were evaluated using the Center for Epidemiological Studies-Depression Scale (CES-D). Results indicated that 30.9% of participants reported depressive symptoms. Multilevel Poisson regression analysis revealed that higher adherence to both dietary patterns was associated with lower prevalence ratios (PRs) of depressive symptoms across quartiles. Specifically, for the traditional diet, the PRs were 1.00 (reference), 0.94 (95% CI, 0.88-0.99), 0.91 (95% CI, 0.85-0.98), and 0.83 (95% CI, 0.80-0.86). For the modified diet, the PRs were 1.00 (reference), 0.94 (95% CI, 0.89-0.98), 0.83 (95% CI, 0.80-0.87), and 0.80 (95% CI, 0.76-0.83). These findings suggest that close adherence to both traditional and modified Japanese diets is associated with fewer depressive symptoms, underscoring the importance of dietary patterns in mental health among the working population.
