Table_1_Association of Dietary Fiber Intake With Myocardial Infarction and Stroke Events in US Adults: A Cross-Sectional Study of NHANES 2011–2018.docx

This study aimed to detect dietary fiber intake and its association with nonfatal cardiovascular/cerebrovascular events (myocardial infarction and stroke) in adults in the United States. This cross-sectional study obtained data from the 2011–2018 National Health and Nutrition Examination Survey database. Using multivariate logistic regression, we compared dietary fiber intake across demographics and detected an association between dietary fiber intake and patient-reported nonfatal myocardial infarction and/or stroke events. We enrolled 8,872 participants (mean dietary fiber intake, 17.38 ± 0.22 g/day). The weighted prevalence of nonfatal cardiovascular/cerebrovascular events was 5.36%, which decreased with higher dietary fiber intake (nonfatal cardiovascular/cerebrovascular events: Tertile1, 6.50%; Tertile2, 5.45%; Tertile3, 4.25%). Higher fiber intake indicated a stable negative association with nonfatal cardiovascular/cerebrovascular events in the multivariate logistic regression analysis, weighted generalized additive model, and smooth curve fitting. Interaction tests showed no significant effect of demographic, socioeconomic, and disease status on the association between dietary fiber intake and nonfatal cardiovascular/cerebrovascular events. Dietary fiber intake was far below the recommended amount. Higher dietary fiber intake was associated with a lower prevalence of nonfatal cardiovascular/cerebrovascular events.

本研究旨在探测美国成人膳食纤维摄入量及其与心血管/脑血管非致命性事件（心肌梗死和中风）的关联。本研究为横断面研究，数据来源于2011-2018年国家健康与营养状况调查数据库。通过多因素逻辑回归分析，我们比较了不同人口统计学特征的膳食纤维摄入量，并发现膳食纤维摄入量与患者报告的非致命性心肌梗死及/或中风事件之间存在关联。本研究共纳入8,872名参与者（平均膳食纤维摄入量为17.38 ± 0.22克/天）。非致命性心血管/脑血管事件的加权患病率为5.36%，该比率随膳食纤维摄入量的增加而降低（非致命性心血管/脑血管事件：三等份1，6.50%；三等份2，5.45%；三等份3，4.25%）。多因素逻辑回归分析、加权广义加性模型及平滑曲线拟合显示，高膳食纤维摄入量与心血管/脑血管非致命性事件呈稳定的负相关。交互作用检验表明，人口统计学、社会经济状况及疾病状态对膳食纤维摄入量与非致命性心血管/脑血管事件之间的关联没有显著影响。膳食纤维摄入量远低于推荐摄入量。高膳食纤维摄入量与心血管/脑血管非致命性事件患病率的降低相关。
