We aimed to assess the association of the oxidative balance score (OBS) with metabolic syndrome (MetS) in adults.
A population-based cross-sectional study . Health centers from five districts in Tehran, Iran.
We recruited 847 participants with an age range of 18-65 years. Dietary intake was assessed by a semiquantitative food frequency questionnaire with 168 items. The OBS was calculated by using the following 13 dietary and nondietary anti- and prooxidant components: dietary antioxidants (selenium, fiber, -carotene, vitamin D, vitamin C, vitamin E, and folate), dietary prooxidants (iron and saturated and polyunsaturated fatty acids), and nondietary anti- (physical activity) and prooxidants (smoking and obesity). The odds ratio (OR) and 95% confidence interval (CI) of the MetS and its components across tertiles of the OBS were calculated by logistic regression analysis, controlling for age, sex, energy intake, occupation, and educational level.
The range of OBS was between 16 and 39. Being in the top versus the bottom tertile of the OBS was not associated with the MetS (OR = 0.71, 95% CI 0.48-1.03; = 0.07), after controlling for potential confounders. Higher OBS score was associated with a lower likelihood of abdominal obesity (OR: 0.55, 95% CI: 0.38-0.81; = 0.003) and increased diastolic blood pressure (OR: 0.64, 95% CI: 0.41-0.99; = 0.04). Higher OBS was not associated with other components of the MetS.
Overall, the present study showed that there was no significant relationship between OBS and MetS in Tehranian adults.
评估氧化平衡评分（OBS）与成年人代谢综合征（MetS）的相关性。
基于人群的横断面研究。伊朗德黑兰五个区的健康中心。
我们招募了 847 名年龄在 18-65 岁之间的参与者。通过 168 项半定量食物频率问卷评估饮食摄入。OBS 是通过以下 13 种饮食和非饮食抗和促氧化剂成分计算得出的：饮食抗氧化剂（硒、纤维、β-胡萝卜素、维生素 D、维生素 C、维生素 E 和叶酸）、饮食促氧化剂（铁以及饱和和多不饱和脂肪酸）和非饮食抗（体力活动）和促氧化剂（吸烟和肥胖）。使用逻辑回归分析，在校正年龄、性别、能量摄入、职业和教育水平后，计算 OBS 三分位的 MetS 及其成分的比值比（OR）和 95%置信区间（CI）。
OBS 的范围在 16 到 39 之间。与 OBS 的最低三分位相比，处于最高三分位与 MetS 无关（OR=0.71，95%CI 0.48-1.03；P=0.07），在控制了潜在混杂因素后。较高的 OBS 评分与腹部肥胖（OR：0.55，95%CI：0.38-0.81；P=0.003）和舒张压升高（OR：0.64，95%CI：0.41-0.99；P=0.04）的可能性降低有关。较高的 OBS 与 MetS 的其他成分无关。
总体而言，本研究表明，德黑兰成年人的 OBS 与 MetS 之间没有显著关系。
