摘要

在澳大利亚,女性报告抑郁症状的比例高于男性。研究表明,富含新鲜水果和蔬菜的饮食模式可以预防抑郁症状。澳大利亚膳食指南建议,每天吃两份水果和五份蔬菜对整体健康是最佳的。然而,对于那些有抑郁症状的人来说,这种消费水平往往很难达到。本研究旨在通过(1)每天两份水果和五份蔬菜(FV7)和(2)每天两份水果和三份蔬菜(FV5)来比较澳大利亚女性长期以来的饮食质量和抑郁症状。资料与方法采用2006年(n = 9145,平均年龄= 30.6,SD = 1.5)、2015年(n = 7186,平均年龄= 39.7,SD = 1.5)和2018年(n = 7121,平均年龄= 42.4,SD = 1.5)三个时间点的澳大利亚妇女健康纵向研究数据进行二次分析。结果线性混合效应模型发现,在调整协变因素后,FV7和FV7之间存在显著的负相关(b =−)。54, 95% ci =−。78,−.29)和FV5 (b =−。38, 95% ci =−。50,−0.26)。这些发现表明水果和蔬菜的摄入与抑郁症状的减少有关。较小的效应量表明在解释这些结果时应谨慎。研究结果还表明,目前的澳大利亚膳食指南建议不需要规定两种水果和五种蔬菜对抑郁症状的影响。结论未来的研究可以评估减少蔬菜摄入量(每天三份)在确定抑郁症状的保护阈值方面的作用。

A longitudinal analysis of Australian women's fruit and vegetable consumption and depressive symptoms

Background

In Australia, women report higher rates of depressive symptoms than men. Research suggests that dietary patterns rich in fresh fruit and vegetables could protect against depressive symptoms. The Australian Dietary Guidelines suggest that consuming two servings of fruit and five serves of vegetables per day is optimal for overall health. However, this consumption level is often difficult for those experiencing depressive symptoms to achieve.

Aims

This study aims to compare diet quality and depressive symptoms in Australian women over time using (I) two serves of fruit and five serves of vegetables per day (FV7), and (ii) two serves of fruit and three serves of vegetables per day (FV5).

Materials and Methods

A secondary analysis was conducted using data from the Australian Longitudinal Study on Women's Health over 12 years at three time points 2006 (n = 9145, Mean age = 30.6, SD = 1.5), 2015 (n = 7186, Mean age = 39.7, SD = 1.5), and 2018 (n = 7121, Mean age = 42.4, SD = 1.5).

Results

A linear mixed effects model found, after adjusting for covarying factors, a small significant inverse association between both FV7 (b = −.54, 95% CI = −.78, −.29) and FV5 (b = −.38, 95% CI = −.50, −.26) in depressive symptoms.

Discussion

These findings suggest an association between fruit and vegetable consumption and decreased depressive symptoms. The small effect sizes indicate caution should be taken in interpreting these results. The findings also suggest that current Australian Dietary Guideline recommendations need not be prescriptive to two fruit and five vegetables for impact on depressive symptoms.

Conclusions

Future research could evaluate reduced vegetable consumption (three serves per day) in identifying the protective threshold for depressive symptoms.
