Inflammation has been proposed to be one of the main causes of musculoskeletal pain. Diet is a lifestyle factor that plays an important role in managing inflammation; thus, we assessed the inflammatory potential of diets using the empirical dietary inflammatory index (EDII) to investigate the relationship between diet and musculoskeletal pain.
This cross-sectional study included 212 elderly individuals who were selected from health centers in Tehran, Iran. Dietary intake was evaluated using a valid and reliable 147-item food frequency questionnaire. To measure the intensity of pain, a visual analogue scale was used. Multiple linear regression was applied to assess the association between the EDII and musculoskeletal pain.
In total, 62.7% and 37.3% of participants had mild and severe pain, respectively. The EDII values were 0.97±0.72 and 1.10±0.66, respectively, in those with mild and severe pain. A higher EDII score was associated with more intense musculoskeletal pain after adjusting for age and sex (β=0.20; 95% confidence interval [CI], 0.06-0.26; p<0.001), but not after adjustment for other confounders (β=-0.13; 95% CI, -1.54 to 0.60; p=0.39).
Our findings indicated that higher dietary inflammation might not be associated with musculoskeletal pain in older adults. However, further investigations are required to confirm these findings.
炎症被认为是肌肉骨骼疼痛的主要原因之一。饮食是一种生活方式因素，在控制炎症方面起着重要作用；因此，我们使用经验性饮食炎症指数（EDII）评估饮食的炎症潜力，以研究饮食与肌肉骨骼疼痛之间的关系。
这项横断面研究纳入了从伊朗德黑兰的健康中心选取的212名老年人。使用一份有效且可靠的包含147个项目的食物频率问卷评估饮食摄入量。使用视觉模拟量表测量疼痛强度。应用多元线性回归评估EDII与肌肉骨骼疼痛之间的关联。
总体而言，分别有62.7%和37.3%的参与者有轻度和重度疼痛。轻度和重度疼痛者的EDII值分别为0.97±0.72和1.10±0.66。在调整年龄和性别后，较高的EDII评分与更强烈的肌肉骨骼疼痛相关（β=0.20；95%置信区间[CI]，0.06 - 0.26；p<0.001），但在调整其他混杂因素后则无关联（β=-0.13；95%CI，-1.54至0.60；p=0.39）。
我们的研究结果表明，较高的饮食炎症可能与老年人的肌肉骨骼疼痛无关。然而，需要进一步的研究来证实这些发现。
