To meet the needs of a diverse patient population, an adequate supply of red blood cells (RBCs) from ethnic/racial minority donors is essential. We previously described the 10-year changes in minority blood donation in the United States. This study describes donation patterns by donor status, age, and race/ethnicity.
Data on the age and the number of unique black/African American, Hispanic/Latino, Asian, and white RBC donors were obtained from eight US blood collectors for 2006, 2009, 2012, and 2015. Donors self-identified their race/ethnicity. First-time (FT) and repeat (R) donors were analyzed separately.
Overall, for both FT and R donor groups, whites constituted the majority of unique donors (FT 66.7% and R 82.7%) and also donated the greatest proportion of RBC units (FT 66.6% and R 83.8%). Donors less than 20 years old comprised the greatest proportion of FT donors for all racial/ethnic groups (39.2%) and had the highest mean number of RBC donations per donor (1.12) among FT donors. Conversely, R donors less than 20 years old had some of the lowest mean number of RBC donations per donor (1.55) among R donors, whereas R donors at least 60 years old had the highest mean (1.88). Year by year, the percentage of FT donors who were less than 20 years old increased for all race/ethnicities. For R donors, whites were more frequently older, while Hispanics/Latinos and Asians were younger.
Greater efforts to convert FT donors less than 20 years into R donors should be undertaken to ensure the continued diversity of the blood supply.
为满足多样化患者群体的需求，从少数族裔/种族捐赠者处获得充足的红细胞（RBC）供应至关重要。我们之前描述了美国少数族裔献血的10年变化情况。本研究描述了按捐赠者状态、年龄和种族/族裔划分的献血模式。
从美国8家血液采集机构获取了2006年、2009年、2012年和2015年独特的黑人/非裔美国人、西班牙裔/拉丁裔、亚裔和白人红细胞捐赠者的年龄及数量数据。捐赠者自行确定其种族/族裔。首次（FT）和重复（R）捐赠者分别进行分析。
总体而言，对于FT和R捐赠者群体，白人构成了独特捐赠者的大多数（FT为66.7%，R为82.7%），并且捐献的红细胞单位比例也最高（FT为66.6%，R为83.8%）。在所有种族/族裔群体中，年龄小于20岁的捐赠者在FT捐赠者中占比最大（39.2%），并且在FT捐赠者中每位捐赠者的红细胞平均献血次数最高（1.12次）。相反，年龄小于20岁的R捐赠者在R捐赠者中每位捐赠者的红细胞平均献血次数处于最低水平（1.55次），而年龄至少60岁的R捐赠者平均献血次数最高（1.88次）。逐年来看，所有种族/族裔中年龄小于20岁的FT捐赠者的百分比都在增加。对于R捐赠者，白人年龄较大的情况更为常见，而西班牙裔/拉丁裔和亚裔则较为年轻。
应做出更大努力，将年龄小于20岁的FT捐赠者转变为R捐赠者，以确保血液供应的持续多样性。
