Substantial evidence provides support for the role of diet in the prevention and control of mental disorders. However, since there is no study regarding the relationship between dietary diversity and stress or depression, we aimed to determine the relationship between the dietary diversity score (DDS) and stress and depression in women.
This descriptive-analytical cross-sectional study was performed on 360 women aged 20-49 years attending health centers in the south of Tehran. The dietary intake and score of depression, anxiety, and stress were measured using a 24-h dietary recall and the 42-item depression, anxiety, stress scales questionnaire, respectively. The DDS was calculated based on the FAO 2013 guidelines. Data were analyzed using Chi-square, analysis of variance, Spearman correlation coefficient, and multivariable logistic regression tests.
In total, 31.4 and 25.8% of the subjects suffered from depression and stress, respectively. After adjusting for confounders, a one-unit increase in DDS was associated with a 39% reduction in the risk of severe depression. The DDS was not significantly associated with mild or moderate depression, and no significant relationship was observed between the DDS and stress.
The DDS could be inversely associated with depression in women. Since we observed no significant relationship between stress and DDS, further studies are needed in this regard.
大量证据支持饮食在预防和控制精神障碍方面的作用。然而，由于尚无关于饮食多样性与压力或抑郁之间关系的研究，我们旨在确定饮食多样性得分（DDS）与女性压力和抑郁之间的关系。
这项描述性分析横断面研究对360名年龄在20 - 49岁、前往德黑兰南部健康中心就诊的女性进行。分别使用24小时饮食回顾法和42项抑郁、焦虑、压力量表问卷来测量饮食摄入量以及抑郁、焦虑和压力得分。DDS根据粮农组织2013年指南进行计算。数据采用卡方检验、方差分析、斯皮尔曼相关系数和多变量逻辑回归检验进行分析。
总体而言，分别有31.4%和25.8%的受试者患有抑郁和压力。在对混杂因素进行调整后，DDS每增加一个单位，严重抑郁风险降低39%。DDS与轻度或中度抑郁无显著关联，且未观察到DDS与压力之间存在显著关系。
DDS可能与女性抑郁呈负相关。由于我们未观察到压力与DDS之间存在显著关系，因此在这方面需要进一步研究。
