We aimed to examine the relationship between dietary glycaemic index (GI) and glycaemic load of foods consumed, intakes of carbohydrates, sugars and fibre, and the prevalence of depressive symptoms in older adults. Data collected from 2334 participants aged 55+ years and 1952 participants aged 60+ years were analysed. Dietary information was collected using a semi-quantitative FFQ. Depressive symptoms were based on antidepressant use or either the 36-Item Short-Form Survey, which included the Mental Health Index (MHI), or the Center for Epidemiologic Studies Depression-10 Scale. Participants in the highest v. lowest tertile of dietary GI intake had increased odds of depressive symptoms (assessed by the MHI scale), multivariable-adjusted OR 1·55 (95 % CI 1·12, 2·14). Participants in the highest compared with lowest tertile of fruit consumption had reduced odds of prevalent depressive symptoms, multivariable-adjusted OR 0·66 (95 % CI 0·46, 0·95). Total fibre, vegetable fibre and breads/cereal fibre intakes were all inversely associated with the prevalence of depressive symptoms, with global P values of 0·03, 0·01 and 0·03, respectively. Participants in the second v. first tertile of vegetable consumption had 41 % reduced odds of prevalent depressive symptoms, multivariable-adjusted OR 0·59 (95 % CI 0·40, 0·88). We show that dietary GI and fibre intakes as well as consumption of fruits and vegetables are associated with the prevalence of depressive symptoms.
我们旨在研究老年人饮食血糖生成指数（GI）与所摄入食物的血糖负荷、碳水化合物、糖及纤维摄入量以及抑郁症状患病率之间的关系。对收集到的2334名55岁及以上参与者和1952名60岁及以上参与者的数据进行了分析。使用半定量食物频率问卷收集饮食信息。抑郁症状基于是否使用抗抑郁药，或基于包含心理健康指数（MHI）的36项简明调查问卷，或流行病学研究中心抑郁量表-10。饮食GI摄入量处于最高三分位数与最低三分位数的参与者出现抑郁症状的几率增加（通过MHI量表评估），多变量调整后的比值比为1.55（95%置信区间1.12, 2.14）。水果摄入量处于最高三分位数与最低三分位数的参与者，其抑郁症状患病率较低，多变量调整后的比值比为0.66（95%置信区间0.46, 0.95）。总纤维、蔬菜纤维和面包/谷物纤维摄入量均与抑郁症状患病率呈负相关，总体P值分别为0.03、0.01和0.03。蔬菜摄入量处于第二三分位数与第一三分位数的参与者，其抑郁症状患病率降低41%，多变量调整后的比值比为0.59（95%置信区间0.40, 0.88）。我们发现饮食GI和纤维摄入量以及水果和蔬菜的消费与抑郁症状患病率相关。
