Studying the contribution of demographic factors to the donor career provides important knowledge to be used for donor management. The aim of this study is to gain insight into donor characteristics, more specifically into the demographic profile of active vs. resigned donors, and multi-gallon vs. occasional donors.
The study population consisted of all registered Dutch whole-blood donors between 1 January 2004 and 1 January 2005 (N = 370 470). The effect of several blood donor characteristics and demographic variables on (i) resigning donating and (ii) being a multi-gallon donor were assessed. Blood donor characteristics were extracted from the blood bank information system and included age, sex, blood group, number of donations and invitations. Demographic characteristics were constituted by population data on urbanization level, socio-economic status (income, housing value), and ethnicity.
Men clearly resigned less often than women (odds ratio (OR) 0.73, 95% confidence interval (CI) 0.72-0.75). Being older than 24 years, having a high income, a high-priced house, living in less urbanized areas or areas with relatively few ethnically diverse people also reduced the stopping risk. With respect to multi-gallon donorship, men were five times more often multi-gallon donor than women (OR 5.27, 95% CI 5.15-5.39) irrespective of the number of donation invitations. Furthermore, multi-gallon donors appeared to live in urbanized areas and have a higher income than occasional donors.
Our results show that different donor profiles can be distinguished. Differences between active and resigned donors include age, the number of donations, sex, socio-economic-status, ethnicity, and urbanization level. The factors highly associated with being a multi-gallon donor are sex, age, socio-economic status, and to a lesser extent urbanization level. Donor profiles do provide the blood bank with knowledge on their donor population, which may be used as valuable information for donor recruitment and retention policies.
研究人口统计学因素对献血者生涯的影响可为献血者管理提供重要知识。本研究旨在深入了解献血者特征，更具体地说，是活跃献血者与退出献血者以及多次献血者与偶尔献血者的人口统计学特征。
研究对象为2004年1月1日至2005年1月1日期间所有登记在册的荷兰全血献血者（N = 370470）。评估了几种献血者特征和人口统计学变量对（i）停止献血和（ii）成为多次献血者的影响。献血者特征从血库信息系统中提取，包括年龄、性别、血型、献血次数和邀请次数。人口统计学特征由城市化水平、社会经济地位（收入、住房价值）和种族的人口数据构成。
男性退出献血的频率明显低于女性（优势比（OR）0.73，95%置信区间（CI）0.72 - 0.75）。年龄超过24岁、高收入、高价住房、生活在城市化程度较低地区或种族多样性相对较少的地区也会降低停止献血的风险。关于多次献血，无论邀请献血次数多少，男性成为多次献血者的可能性是女性的五倍（OR 5.27，95% CI 5.15 - 5.39）。此外，多次献血者似乎生活在城市化地区，且收入高于偶尔献血者。
我们的结果表明，可以区分不同的献血者特征。活跃献血者与退出献血者之间的差异包括年龄、献血次数、性别、社会经济地位、种族和城市化水平。与成为多次献血者高度相关的因素是性别、年龄、社会经济地位，以及在较小程度上的城市化水平。献血者特征确实为血库提供了有关其献血者群体的知识，这可作为献血者招募和保留政策的宝贵信息。
