Mental health disorders are a leading cause of disability worldwide, including in first-time mothers. Understanding the associations between diet and depressive symptoms could assist in improving mental health status in this group.
Our aim was to determine the association between diet quality, fruit, vegetable, and fish consumption and depressive symptoms in first-time mothers aged 19 to 45 years.
We analyzed cross-sectional, baseline data (3 months postpartum) from the Melbourne InFANT (Infant Feeding, Activity, and Nutrition Trial) Extend Program.
PARTICIPANTS/SETTING: Participants were first-time Australian mothers aged 19 to 45 years from the Geelong and Melbourne regions of Victoria, Australia (n=457).
A self-administered, 137-item food frequency questionnaire assessed dietary intake over the past year. Adherence to the 2013 Australian Dietary Guidelines was assessed using the Dietary Guideline Index as a measure of diet quality. Depressive symptoms were determined using the Center for Epidemiologic Studies Depression Scale.
Relationships between diet quality, fruit, vegetable, and fish intake and depressive symptoms were investigated using linear regression adjusted for relevant covariates (age, smoking status, sleep quality, education, physical activity status, and body mass index).
Better diet quality, as indicated by a higher score on the Dietary Guideline Index, was associated with lower depressive symptoms after adjusting for relevant covariates (β=-.034; 95% CI -.056 to -0.012). There were no other associations between dietary intake and depressive symptoms.
Adherence to the Australian Dietary Guidelines was associated with better mental health status among first-time mothers. Further research, including longitudinal and intervention studies, are required to determine causality between dietary intake and depressive symptoms, which might help inform future public health nutrition programs for this target group.
精神健康障碍是全球范围内导致残疾的主要原因之一，包括初产妇。了解饮食与抑郁症状之间的关联有助于改善这一群体的心理健康状况。
本研究旨在确定初产妇（19-45 岁）的饮食质量、水果、蔬菜和鱼类摄入与抑郁症状之间的关联。
我们分析了澳大利亚墨尔本的墨尔本婴儿喂养、活动和营养试验扩展计划的横断面、基线数据（产后 3 个月）。
参与者/设置：参与者为来自澳大利亚维多利亚州吉朗和墨尔本地区的初产妇（19-45 岁）（n=457）。
采用 137 项食物频率问卷评估过去一年的饮食摄入情况。使用饮食指南指数评估对 2013 年澳大利亚饮食指南的依从性，作为衡量饮食质量的指标。采用流行病学研究中心抑郁量表评估抑郁症状。
使用线性回归调整相关协变量（年龄、吸烟状况、睡眠质量、教育程度、身体活动状况和体重指数）后，研究饮食质量、水果、蔬菜和鱼类摄入与抑郁症状之间的关系。
调整相关协变量后，饮食指南指数得分较高（提示饮食质量较好）与抑郁症状较低相关（β=-.034；95%CI：-.056 至-.012）。饮食摄入与抑郁症状之间没有其他关联。
遵守澳大利亚饮食指南与初产妇的心理健康状况较好有关。需要进一步的研究，包括纵向研究和干预研究，以确定饮食摄入与抑郁症状之间的因果关系，这可能有助于为这一目标群体制定未来的公共卫生营养计划。
