The likelihood of donating blood changes over the life course, with life events shown to influence entry to and exit from the donor population. While these previous findings provide valuable insights for donor management, blood collection agencies need to be cautious about generalizing findings to other countries as blood donor behaviour is context-specific. To examine cross-country variations in donor behaviour, the repeatability of a previous Dutch study on life events and blood donor lapse is examined by using a sample of Danish donors.
Register data from Statistics Denmark was linked to the Scandinavian Donations and Transfusions database (n = 152 887). Logistic regressions were conducted to examine the association between life events in 2009-2012 and blood donor lapse in 2013-2014.
Of the total sample, 69 079 (45·2%) donors lapsed. Childbirth and losing a job increased the lapsing risk by 11% and 16%, respectively, while health-related events in the family (i.e. blood transfusion, disease and death) decreased the lapsing risk by 5%, 7% and 9%, respectively.
Life events are associated with donor lapse of Danish donors. These results are comparable to previous findings from the Netherlands (i.e. childbirth and labour market transitions increased lapsing risk; health-related events decreased lapsing risk), with two thirds of the associations being in the same direction. Differences between study results were mainly related to effect sizes and demographic compositions of the donor pools. We argue contextual factors to be of importance in blood donor studies.
献血的可能性会随着人生历程而变化，生活事件被证明会影响献血人群的进入和退出。虽然这些先前的研究结果为献血者管理提供了有价值的见解，但由于献血者行为具有特定的背景，血液采集机构需要谨慎地将这些发现推广到其他国家。为了研究献血者行为的跨国差异，使用丹麦献血者的样本，检验了先前一项关于生活事件和献血者退出的荷兰研究结果的可重复性。
从丹麦统计局获得的登记数据与斯堪的纳维亚献血和输血数据库（n=152887）相关联。采用逻辑回归分析检验了 2009-2012 年生活事件与 2013-2014 年献血者退出之间的关联。
在总样本中，有 69079 名（45.2%）献血者退出。分娩和失业分别使退出风险增加了 11%和 16%，而家庭中的健康相关事件（即输血、疾病和死亡）使退出风险分别降低了 5%、7%和 9%。
生活事件与丹麦献血者的献血退出有关。这些结果与荷兰的先前研究结果相似（即分娩和劳动力市场转变增加了退出风险；健康相关事件降低了退出风险），其中三分之二的关联方向相同。研究结果之间的差异主要与献血人群的效应大小和人口构成有关。我们认为，背景因素在献血者研究中很重要。
