虽然有几种营养素和食物被认为可以预防产后抑郁症，但之前的所有研究都主要集中在单一营养素或食物上。相比之下，对饮食模式的研究，即通过考虑营养累积效应来衡量整体饮食，可能会为饮食对产后抑郁症的影响提供新的见解。我们前瞻性地调查了865名日本妇女孕期饮食模式与产后抑郁风险之间的关系。饮食通过有效的自填式饮食历史问卷进行评估。通过因子分析从33个预先定义的食物组(能量调整食物(g/d))中提取了饮食模式。当受试者在产后2-9个月时爱丁堡产后抑郁量表评分>；=9时，产后抑郁症被定义为存在。共有121名妇女(14.0%)被归类为产后抑郁症。研究确定了三种饮食模式：健康饮食模式、西方饮食模式和日式饮食模式。在调整潜在的混杂因素后，无论是“健康的”还是“日本的”模式都与产后抑郁的风险无关。与西方模式的第一个四分位数相比，只有第二个四分位数与产后抑郁的风险降低独立相关(多变量OR 0.52，95%CI 0.30，0.93)，尽管没有观察到明显的暴露-反应关联(趋势P=0.36)。目前的研究未能证实饮食模式和产后抑郁风险之间的明确联系。进一步的研究需要更准确的测量，以确认饮食模式与产后抑郁风险之间的关系。
Although several nutrients and foods are suggested to be preventive against postpartum depression, all previous studies have primarily focused on single nutrients or foods. In contrast, studies on dietary patterns, namely the measurement of overall diet by considering the cumulative effects of nutrient, may provide new insights into the influence of diet on postpartum depression. We prospectively examined the association between dietary patterns during pregnancy and the risk of postpartum depression among 865 Japanese women. Diet was assessed with a validated, self-administered diet history questionnaire. Dietary patterns from thirty-three predefined food groups (energy-adjusted food (g/d)) were extracted by factor analysis. Postpartum depression was defined as present when the subjects had an Edinburgh Postnatal Depression Scale score of >= 9 at 2-9 months postpartum. A total of 121 women (14.0%) were classified as having postpartum depression. Three dietary patterns were identified: 'Healthy', 'Western' and 'Japanese' patterns. After adjustment for potential confounders, neither the 'Healthy' nor the 'Japanese' pattern was related to the risk of postpartum depression. Compared with the first quartile of the 'Western' pattern, only the second quartile was independently related to a decreased risk of postpartum depression (multivariate OR 0.52, 95% CI 0.30, 0.93), although no evident exposure-response associations were observed (P for trend=0.36). The present study failed to substantiate clear associations between dietary patterns and the risk of postpartum depression. Further studies with more accurate measurements are warranted to confirm the relationship between dietary patterns and the risk of postpartum depression.
