Objective

The present study was designed to examine the relationship between the dietary inflammatory index (DII) and depression, anxiety and stress in Iranian men with spinal cord injury (SCI).

Design

Cross-sectional study.

Setting

Mottahary SCI clinic, Isfahan, Iran.

Participants

The current study was conducted on 150 men with SCI aged 40–65 years.

Outcome Measures

Dietary data were collected using a semi-quantitative 148 item food frequency questionnaire (FFQ). The Depression, Anxiety, Stress Scale-21 (DASS-21) was used to assess the psychological profile of the participants.

Results

The DII score ranged from −3.62 to 4.02. Overall, 34% of study participants had at least mild levels of depression and anxiety symptoms and 25% had at least mild levels of stress symptoms. A one-unit increase in the DII was significantly associated with higher scores of depressive symptoms (β = 1.31, 95% CI 0.44–2.18; P = 0.003). Also, a one-unit increase in the DII was associated with higher odds of having at least mild depressive symptoms (OR = 1.77, 95% CI 1.17, 2.67; P = 0.007). No significant association was found between the DII and anxiety and stress.

Conclusion

The present study indicated that a higher DII score is associated with higher odds of depressive symptoms in men with SCI. These initial findings highlight the crucial role of the inflammatory potential of diet in the mental health of subjects with SCI. Future prospective studies are warranted to confirm these findings.

脊髓损伤男性饮食炎症指数与心理特征的相关性

客观的

本研究旨在检查伊朗男性脊髓损伤 (SCI) 患者的饮食炎症指数 (DII) 与抑郁、焦虑和压力之间的关系。

设计

横断面研究。

环境

Mottahary SCI 诊所，伊朗伊斯法罕。

参加者

目前的研究是对 150 名 40-65 岁的 SCI 男性进行的。

结果措施

使用半定量的 148 项食物频率问卷 (FFQ) 收集膳食数据。抑郁、焦虑、压力量表 21 (DASS-21) 用于评估参与者的心理状况。

结果

DII 得分范围为 -3.62 至 4.02。总体而言，34% 的研究参与者至少有轻度抑郁和焦虑症状，25% 至少有轻度压力症状。DII 增加一个单位与较高的抑郁症状评分显着相关（β  = 1.31，95% CI 0.44–2.18；P = 0.003）。此外，DII 增加一个单位与至少出现轻度抑郁症状的几率更高相关（OR = 1.77，95% CI 1.17，2.67；P = 0.007）。在 DII 与焦虑和压力之间没有发现显着关联。

结论

本研究表明，较高的 DII 分数与 SCI 男性抑郁症状的几率较高有关。这些初步发现强调了饮食的炎症潜能在 SCI 患者的心理健康中的关键作用。未来的前瞻性研究有必要证实这些发现。
