- Abstract
<bold>Background: </bold>Wholegrains contribute a range of beneficial nutrients, such as dietary fiber and several minerals and vitamins, that are beneficial to depressive symptoms. However, there are a few studies aimed at exploring whether a wholegrain diet is related to depressive symptoms. We conducted this study to investigate the relationship between wholegrains consumption and depressive symptoms.<bold>Methods: </bold>This cross-sectional study included a total of 24,776 (mean age: 39.9 years, age range: 18.1-91.3 years; males, 54.1%) inhabitants living in Tianjin, China. Wholegrains consumption was assessed using a valid self-administered food frequency questionnaire. Depressive symptoms were evaluated using the Chinese version of Zung Self-Rating Depression Scale (SDS) and the cutoff point was set at 45. Multiple logistic regression analysis was used to estimate the relationship between wholegrains consumption and depressive symptoms.<bold>Results: </bold>The prevalence of depressive symptoms was 19.1% and 22.4% in males and females, respectively. After adjustments for potential confounding factors, the odds ratios (95% confidence intervals) of depressive symptoms across wholegrains consumption were 0.77 (0.65-0.91) for <1 time/week, 0.73 (0.62-0.86) for 1 time/week and 0.68 (0.59-0.79) for ≥2 time/week in males compared with the control group (almost never). In females, the odds ratios (95% confidence intervals) were 0.86 (0.71-1.04) for <1 time/week, 0.94 (0.78-1.13) for 1 time/week, and 0.76 (0.65-0.91) for ≥2 time/week. Similar results were observed when we use other cut-offs (SDS ≥ 40 and 50) to define depressive symptoms.<bold>Conclusion: </bold>This study first demonstrated that the higher consumption of wholegrains might have effects on the prevention and improvement of depressive symptoms. Prospective or intervention studies are needed to confirm these findings.
