黄酮类化合物是具有促进健康特性的多酚类植物化学物质，但关于高危人群摄入量的知识有限。本研究旨在估计总黄酮和六类黄酮的摄入量在健康老龄化的多样性社区的整个生命周期（HANDLS）研究;确定是否存在种族（非裔美国人（AA）和白色（W））和收入（< or >125%联邦贫困指南）的摄入量差异;并比较摄入量与具有相似人口统计学和社会经济特征的全国代表性人口。在进行统计检验之前，数据转换将类黄酮摄入量分布归一化。除黄烷酮类外，AA组的类黄酮摄入量显著低于W组（p < 0.01），而不考虑其他潜在的中介因素，包括性别、年龄和收入。总黄酮摄入量在手没有不同的摄入量在全国代表性的研究，但花青素和黄酮的摄入量较低，种族特异性差异被发现几类黄酮。这些发现意味着，由于类黄酮消费的好处可能不会被AA和白人同样经历，也不会在弱势群体中，如相对于美国人口的HANDLS所代表的人群中，并且可能在观察到的健康差异中发挥作用。
Flavonoids are polyphenolic phytochemicals with health-promoting properties, yet knowledge about their intake in at-risk populations is limited. This study sought to estimate intakes of total flavonoids and six flavonoid classes in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study; determine if differences in intakes exist by race (African American (AA) and White (W)) and income (< or >125% Federal poverty guidelines); and compare intakes to those of a nationally representative population with similar demographic and socioeconomic characteristics. Data transformation normalized the flavonoid intake distributions prior to conducting statistical tests. With the exception of the flavanone class, flavonoid intakes of AAs were significantly lower than those of W (p < 0.01), regardless of other potential mediating factors including sex, age, and income. Total flavonoid intakes in HANDLS did not differ from intakes in the nationally representative study, but anthocyanidin and flavone intakes were lower, and race specific differences were found for several flavonoid classes. These findings imply that benefits attributable to flavonoid consumption may not be experienced equally by AAs and Whites, nor in vulnerable populations such as that represented by HANDLS relative to the U.S. population, and may play a role in observed health disparities.
