The Human Milk Banking Association of North America (HMBANA) is a nonprofit association that standardizes and facilitates the establishment and operation of nonprofit donor human milk banks in North America. Few studies have examined milk donor characteristics and geographic distribution, and little is known about how donor characteristics change with time. We performed a retrospective cohort study of mothers who donated to Mothers' Milk Bank Northeast (MMBNE) between January 1, 2011 and September 1, 2019. Data collected from MMBNE donor surveys and collection procedures were analyzed using descriptive and comparative statistics. Donor characteristics were examined for secular trends. Donors ( = 3,764) were of mean age 32.5 years (median 32; IQR 30-35) and most donated more than once (median 2; IQR 1-3; range 1-41). The majority of donors gave birth to term infants and resided in New England; however, MMBNE donors were located in 39 states at the time of donation. Median total volume donated per donor was median 11,396 mL (380 Oz); IQR 6,020-24,242 mL. Mothers of preterm compared with term infants were more likely to be bereaved ( < 0.01) and donated larger volumes ( < 0.01). Over time, number of first-time donors increased, although donors became less likely to have preterm infants or to reside in Massachusetts or New England. Donors to MMBNE varied greatly in age and were broadly distributed geographically. Donor characteristics changed substantially over time. Enhanced understanding of the characteristics of donors may improve the efficiency of efforts to promote milk donation.
北美人类母乳银行协会（HMBANA）是一个非营利性协会，负责规范和促进北美非营利性捐赠人母乳库的建立和运营。很少有研究调查母乳捐赠者的特征和地域分布情况，也不太了解捐赠者特征随时间的变化情况。我们对 2011 年 1 月 1 日至 2019 年 9 月 1 日期间向东北部母乳银行（MMBNE）捐赠母乳的母亲进行了回顾性队列研究。从 MMBNE 捐赠者调查和采集程序中收集的数据使用描述性和比较性统计方法进行了分析。检查了捐赠者特征的长期趋势。捐赠者（ = 3764）的平均年龄为 32.5 岁（中位数 32；IQR 30-35），大多数人不止一次捐赠（中位数 2；IQR 1-3；范围 1-41）。大多数捐赠者的婴儿为足月产，居住在新英格兰地区；然而，在捐赠时，MMBNE 捐赠者分布在 39 个州。每位捐赠者的平均总捐赠量为中位数 11396 毫升（380 盎司）；IQR 6020-24242 毫升。与足月产婴儿相比，早产儿的母亲更有可能失去亲人（ < 0.01），捐赠量更大（ < 0.01）。随着时间的推移，首次捐赠者的数量有所增加，尽管捐赠者的早产儿数量减少，且来自马萨诸塞州或新英格兰地区的人数减少。MMBNE 的捐赠者在年龄上差异很大，在地理上分布广泛。随着时间的推移，捐赠者的特征发生了重大变化。增强对捐赠者特征的了解可能会提高促进母乳捐赠的效率。
