This study aimed to evaluate associations between plant-based diets and the prevalence of depressive symptoms (DepS) among Chinese middle-aged and older adults. This study included 3153 participants aged 45 and older. Dietary intake was collected using a food frequency questionnaire, and DepS was evaluated using the 9-item Patient Health Questionnaire. Foods were classified into 17 groups and three plant-based diet indices were created, including the overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI). Compared to the lowest quartile, participants in the highest quartile of hPDI had lower odds of DepS (OR = 0.60; 95% CI: 0.40, 0.89). Conversely, the highest quartile of the uPDI was associated with higher odds of DepS (OR = 1.81; 95% CI: 1.16, 2.82). These findings supported that the quality of plant-based diets matters for mental health.
本研究旨在评估中国中老年人群中植物性饮食与抑郁症状（DepS）患病率之间的关联。本研究纳入了3153名45岁及以上的参与者。通过食物频率问卷收集饮食摄入量，并使用9项患者健康问卷评估DepS。食物被分为17组，并创建了三种植物性饮食指数，包括总体植物性饮食指数（PDI）、健康植物性饮食指数（hPDI）和不健康植物性饮食指数（uPDI）。与最低四分位数相比，hPDI最高四分位数的参与者出现DepS的几率较低（OR = 0.60；95% CI：0.40，0.89）。相反，uPDI最高四分位数与DepS的较高几率相关（OR = 1.81；95% CI：1.16，2.82）。这些发现支持了植物性饮食的质量对心理健康很重要。
