摘要

目的:膳食抗氧化综合指数(CDAI)是一种新颖、全面的评估膳食抗氧化潜力的方法。我们旨在探索 CDAI 与年龄≥ 40 岁的美国成年人腹主动脉钙化(AAC)之间的联系:这项横断面研究从 2013-2014 年美国国家健康与营养调查(NHANES)数据库中收集了年龄≥ 40 岁人群的饮食和腹主动脉钙化数据。采用六种膳食抗氧化剂计算 CDAI。AAC采用称为AAC-24的半定量评分系统进行评估,AAC评分大于6分为严重AAC(SAAC)。为了研究 CDAI 与 AAC(包括 SAAC)之间的关系,采用了衬线/逻辑回归分析和平滑曲线拟合:本研究共纳入 2,640 名参与者,观察到随着 CDAI 水平的升高,AAC 评分和 SAAC 患病率显著下降(P 结论:随着 CDAI 水平的升高,AAC 评分和 SAAC 患病率显著下降(P 结论:随着 CDAI 水平的升高,AAC 评分和 SAAC 患病率显著下降):以 CDAI 定量的膳食抗氧化剂摄入量与 AAC 风险呈反比关系。有必要开展更多的纵向和干预研究。

Composite dietary antioxidant index and abdominal aortic calcification: a national cross-sectional study.

Purpose: The Composite Dietary Antioxidant Index (CDAI) is a novel, inclusive measure for evaluating the antioxidant potential of diets. We aim to explore the link between the CDAI and abdominal aortic calcification (AAC) in U.S. adults aged ≥ 40 years.

Methods: This cross-sectional study collected dietary and AAC data for individuals aged ≥ 40 years from the 2013-2014 National Health and Nutrition Examination Survey (NHANES) database. The CDAI was calculated using six dietary antioxidants. AAC was evaluated using a semi-quantitative scoring system known as AAC-24, with an AAC score greater than 6 as severe AAC (SAAC). To examine the association between CDAI and AAC, including SAAC, liner/logistic regression analyses and smooth curve fitting were applied.

Results: A total of 2,640 participants were included in this study, and significant decreases in AAC score and SAAC prevalence were observed with ascending CDAI levels (P < 0.01). After adjusting for confounding factors, a clear link was established between the CDAI and both AAC score (β = -0.083, 95% CI -0.144-0.022, P = 0.008) and SAAC (OR = 0.883, 95% CI 0.806-0.968, P = 0.008), respectively. Further smooth curve fitting indicated a negative correlation between CDAI and both AAC score and SAAC.

Conclusions: Dietary antioxidant consumption, as quantified by the CDAI, shows an inverse relationship with AAC risk. Additional longitudinal and intervention studies are essential.

期刊介绍: Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
