This cross-sectional study aimed to explore the relationship between diet quality, dietary diversity, and oxidative stress levels in older adults in parts of the Ningxia Hui Autonomous Region in northwestern China. A total of 335 participants voluntarily participated in the study from April to July 2021. Laboratory tests and questionnaires were used to obtain general characteristics, dietary conditions, and indicators of oxidative stress. The dietary diversity scores of the participants were 5.20±1.39, the diet quality indices were 56.91±11.14, and most had poor diet quality. The levels of the oxidative stress markers malondialdehyde, superoxide dismutase, 8-iso-prostaglandin F2α, and total antioxidant capacity were 4.77±1.77, 40.33±9.85, 763.10±245.41, and 1.02±0.14, respectively. The results showed that the diet quality scores of participants were related to dietary diversity and whether the scores passed or not was significantly related to total antioxidant capacity.
这项横断面研究旨在探讨中国西北部宁夏回族自治区部分地区老年人的饮食质量、饮食多样性与氧化应激水平之间的关系。2021年4月至7月，共有335名参与者自愿参加了该研究。通过实验室检测和问卷调查获取一般特征、饮食状况以及氧化应激指标。参与者的饮食多样性得分是5.20±1.39，饮食质量指数是56.91±11.14，且大多数人的饮食质量较差。氧化应激标志物丙二醛、超氧化物歧化酶、8-异前列腺素F2α和总抗氧化能力水平分别为4.77±1.77、40.33±9.85、763.10±245.41和1.02±0.14。结果表明，参与者的饮食质量得分与饮食多样性有关，得分是否及格与总抗氧化能力显著相关。
