Background: A vegetarian diet may be a risk factor for depression, but this relationship was unclear in the elderly Chinese population.Methods: Self-report data were gathered from 1051 elderly persons using the Cohort of Elderly Health and Environment Controllable Factors, which was created in West Anhui, China. The depressive symptoms were set as binary, ordinal, and continuous outcomes, respectively, whereas the dietary structures were computed as an ordinal variable and a dummy variable. Multiple logistic regression, ordinal regression, and linear regression were used to assess the relationship by adjusting the potential confounding variables with p-values of <0.1 in univariate analysis.Results: The elderly participants who had a vegetable-based diet had the highest GDS scores of 8.78 ± 6.894 (p = 0.001) and the highest rate of depression (32.9%, p = 0.003). After adjustment for the potential confounders, elderly men who had a vegetable-based diet had a higher rate of depression (OR[95%CI]: 1.62[1.07-2.46], 4.71[1.38-16.03]), more severe symptoms of depression (OR[95%CI]: 8.85[2.94-34.12]), and higher GDS scores (β[95%CI]: 1.46[0.70-2.22], 2.97[1.28-4.67]) than male participants who had a meat-based diet, but this was not the case in women.Limitations: All data were self-reported. The study lacked quantitatively evaluated dietary intake. The duration of the current dietary structures and comorbidities were not reported. The cross-sectional study made the causal role uncertain.Conclusions: Vegetarian diets may pose a greater risk of depressive symptoms among the elderly Chinese population, especially elderly men. Given the cross-sectional nature of this study, the causal role was uncertain. Further prospective studies, in particular among elderly women, are needed. [ABSTRACT FROM AUTHOR]- Published
