Inflammatory-related chronic diseases are increasing in Iran with high consumption of a diet containing pro-inflammatory potential and a sedentary lifestyle. The empirical dietary inflammatory index (EDII) was developed as a tool to assess dietary effects on systemic inflammation. We examined the hypothesis that specific dietary patterns reflecting systemic inflammation are associated with cardiorespiratory fitness (CRF) in Tehranian adults.
This cross-sectional study was carried out on 270 adults who are residents of Tehran. Dietary intake was assessed using a 168-item valid and reliable food frequency questionnaire. The EDII score was developed according to participant dietary intakes of 21-item pre-defined food groups. CRF was assessed by using a graded exercise treadmill test. Anthropometric measurements were assessed using standard methods. To discover the association between CRF and EDII, we used multivariable logistic regression analysis.
Those who were in the third tertile of the EDII had 57% lower odds of having better VO (ml/kg/min) than those in the first tertile (OR: 0.43; 95% CI: 0.16, 1.12, = 0.01). There were no significant differences between tertiles of the EDII score in terms of VO2 (L·min) and VO2 (LBM) before and after adjusting for confounders. There was a significant decrease in VO (ml/kg/min) across tertiles of the EDII after controlling for covariates (-value = 0.04). There was a significant inverse association between the EDII score and VO (ml/kg/min) (β = -0.35, = 0.001).
Our finding demonstrated that a higher EDII might be associated with lower CRF in Tehranian adults. Prospective studies are needed to shed light on the causal link between the EDII and CRF.
在伊朗，随着含有促炎潜力的饮食的高消费和久坐不动的生活方式，与炎症相关的慢性病正在增加。经验性饮食炎症指数（EDII）被开发为一种评估饮食对全身炎症影响的工具。我们检验了这样一个假设，即在德黑兰成年人中，反映全身炎症的特定饮食模式与心肺适能（CRF）相关。
这项横断面研究是对270名德黑兰居民成年人进行的。使用一份包含168个项目的有效且可靠的食物频率问卷评估饮食摄入量。EDII分数是根据参与者对21个预先定义食物组的饮食摄入量得出的。通过分级运动平板试验评估CRF。使用标准方法评估人体测量指标。为了发现CRF与EDII之间的关联，我们使用了多变量逻辑回归分析。
处于EDII第三三分位数的人比处于第一三分位数的人具有更好的VO（毫升/千克/分钟）的几率低57%（比值比：0.43；95%置信区间：0.16，1.12，P = 0.01）。在调整混杂因素前后，EDII分数三分位数在VO2（升/分钟）和VO2（去脂体重）方面没有显著差异。在控制协变量后，EDII三分位数间的VO（毫升/千克/分钟）有显著下降（P值 = 0.04）。EDII分数与VO（毫升/千克/分钟）之间存在显著的负相关（β = -0.35，P = 0.001）。
我们的研究结果表明，较高的EDII可能与德黑兰成年人较低的CRF相关。需要进行前瞻性研究以阐明EDII与CRF之间的因果联系。
