We aimed to assess the potential association of dietary (DIS) and lifestyle inflammation score (LIS) and their joint association (DLIS) with cardiorespiratory fitness (CRF) in Tehranian adults.
The present study was designed cross-sectional.
A total of 265 males and females aged 18-70 years (mean ± SD: 36.9 ± 13.3) were entered in the present cross-sectional study. Eligible participants were healthy men and women who were free of medications and had no acute or chronic infection or inflammatory disease.
The DIS was calculated by the use of data from 18 anti- and pro-inflammatory dietary components, and the LIS by three non-dietary components including physical activity, smoking status, and general adiposity, with higher scores indicating a more pro-inflammatory diet and lifestyle, respectively. The DLIS was calculated by summing the DIS and LIS. CRF was assessed by the Bruce protocol and VO max was measuredas the main variable of CRF. The odds ratio (OR) and 95% confidence interval (CI) of CRF across tertiles of the DIS, LIS, and DLIS were estimated by logistic regression analysis with considering age, gender, energy intake, marital and education status, and occupation as confounders.
The DLIS ranged from -2.10 to 0.38 (mean ± SD: -1.25 ± 0.64). In the model that controlled for all variables, the ORs of CRF for the second and third tertiles of the DLIS as compared to the first tertile were 0.42 (95%CI: 0.20, 0.90) and 0.12 (95%CI: 0.05, 0.32), respectively (P-trend < 0.001). There was a strong inverse association between the LIS and CRF (OR: 0.12, 95%CI: 0.05, 0.32). There was no association between DIS and CRF.
The present study examined the joint association of inflammation-related lifestyle behaviors with CRF and found a strong inverse association between a pro-inflammatory lifestyle with CRF. We did not find any association between dietary inflammatory properties with CRF. Future studies should address the relationship between the inflammatory potential of the diet and CRF.
我们旨在评估德黑兰成年人的饮食炎症评分（DIS）和生活方式炎症评分（LIS）及其联合评分（DLIS）与心肺适能（CRF）之间的潜在关联。
本研究为横断面研究。
共有265名年龄在18至70岁之间的男性和女性（平均±标准差：36.9±13.3）纳入本横断面研究。符合条件的参与者为健康的男性和女性，他们未服用药物，也没有急性或慢性感染或炎症性疾病。
DIS通过使用18种抗炎和促炎饮食成分的数据计算得出，LIS通过包括身体活动、吸烟状况和总体肥胖在内的三种非饮食成分计算得出，分数越高分别表明饮食和生活方式的促炎程度越高。DLIS通过将DIS和LIS相加计算得出。CRF通过布鲁斯方案进行评估，VO₂max作为CRF的主要变量进行测量。通过逻辑回归分析，以年龄、性别、能量摄入、婚姻和教育状况以及职业作为混杂因素，估计DIS、LIS和DLIS三分位数组中CRF的比值比（OR）和95%置信区间（CI）。
DLIS范围为-2.10至0.38（平均±标准差：-1.25±0.64）。在控制所有变量的模型中，与第一三分位数组相比，DLIS第二和第三三分位数组的CRF的OR分别为0.42（95%CI：0.20，0.90）和0.12（95%CI：0.05，0.32）（P趋势<0.001）。LIS与CRF之间存在强烈的负相关（OR：0.12，95%CI：0.05，0.32）。DIS与CRF之间无关联。
本研究探讨了与炎症相关的生活方式行为与CRF的联合关联，发现促炎性生活方式与CRF之间存在强烈的负相关。我们未发现饮食炎症特性与CRF之间存在任何关联。未来的研究应探讨饮食的炎症潜力与CRF之间的关系。
