The association between dietary antioxidant quality score (DAQS) and cardiovascular risk factors such as low cardiovascular fitness (CRF) and elevated blood pressure (BP) has rarely been investigated. To investigate the association between DAQS, CRF, and BP. This cross-sectional study was conducted on 270 adult subjects living in Tehran, Iran. Dietary intake was evaluated using a validated food frequency questionnaire. The DAQS was calculated using antioxidant-nutrient intake. Socio-economic status, anthropometric measures, and BP were recorded by a trained interviewer, using standard methods. A significant increase was found in maximal oxygen uptake (p value = 0.01) across tertiles of DAQS. After adjusting for confounders, the association remained unchanged (p value = 0.02). Participants in the highest tertile of DAQS had higher systolic BP (SBP) (p value = 0.01) and diastolic BP (DBP) (p value = 0.03), although adjustment for confounding factors attenuated the results (p value = 0.3 for DBP and p value = 0.6 for SBP). Our results revealed that higher DAQS is associated with better CRF in Iranian adults. Further studies are needed to establish the veracity of our results.
饮食抗氧化质量评分（DAQS）与心血管风险因素之间的关联，如低心血管适能（CRF）和血压（BP）升高，鲜有研究。为了探究DAQS、CRF和BP之间的关联。本横断面研究针对居住在伊朗德黑兰的270名成年受试者开展。使用经过验证的食物频率问卷评估饮食摄入量。DAQS通过抗氧化营养素摄入量计算得出。社会经济状况、人体测量指标和血压由经过培训的访谈员使用标准方法记录。在DAQS三分位数中，最大摄氧量显著增加（p值 = 0.01）。在对混杂因素进行调整后，这种关联保持不变（p值 = 0.02）。DAQS最高三分位数的参与者收缩压（SBP）较高（p值 = 0.01），舒张压（DBP）较高（p值 = 0.03），尽管对混杂因素进行调整后结果有所减弱（DBP的p值 = 0.3，SBP的p值 = 0.6）。我们的结果显示，较高的DAQS与伊朗成年人更好的CRF相关。需要进一步研究以确定我们结果的真实性。
