使用探索性和预先定义的方法，抑郁症与整体饮食有关。然而，这两种方法都没有纳入营养与疾病相关的具体知识。本研究的目的是经验性地确定饮食模式，使用降秩回归，并检查其关系的抑郁症状。参与者是2006名年龄在19-69岁之间的日本雇员。使用流行病学研究中心抑郁量表评估抑郁症状。使用经验证的自我管理的饮食史问卷对饮食进行评估。饮食模式提取的降秩回归6抑郁相关的营养素作为响应变量。Logistic回归用于估计调整潜在混杂因素后抑郁症状的优势比。高摄入蔬菜、蘑菇、海藻、豆制品、绿色茶、土豆、水果和带骨小鱼以及低摄入大米的饮食模式与较少的抑郁症状相关。在饮食评分最高与最低三分位数中，有抑郁症状的多变量校正比值比为0.62（95%置信区间，0.48-0.81）。结果表明，坚持富含蔬菜，水果和典型的日本食品，包括蘑菇，海藻，大豆制品和绿色茶的饮食与抑郁症状的可能性较低有关。(C)2015爱思唯尔爱尔兰有限公司版权所有。
Depression has been linked to the overall diet using both exploratory and pre-defined methods. However, neither of these methods incorporates specific knowledge on nutrient-disease associations. The aim of the present study was to empirically identify dietary patterns using reduced rank regression and to examine their relations to depressive symptoms. Participants were 2006 Japanese employees aged 19-69 years. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Diet was assessed using a validated, self-administered diet history questionnaire. Dietary patterns were extracted by reduced rank regression with 6 depression-related nutrients as response variables. Logistic regression was used to estimate odds ratios of depressive symptoms adjusted for potential confounders. A dietary pattern characterized by a high intake of vegetables, mushrooms, seaweeds, soybean products, green tea, potatoes, fruits, and small fish with bones and a low intake of rice was associated with fewer depressive symptoms. The multivariable-adjusted odds ratios of having depressive symptoms were 0.62 (95% confidence interval, 0.48-0.81) in the highest versus lowest tertiles of dietary score. Results suggest that adherence to a diet rich in vegetables, fruits, and typical Japanese foods, including mushrooms, seaweeds, soybean products, and green tea, is associated with a lower probability of having depressive symptoms.
