As Japan's aging society needs more blood, young students comprise a progressively smaller portion of the donor pool. To ensure a safe and sustainable blood supply, it is crucial to select suitable donors. This study aims to evaluate donor deferral rates, causes of deferral, and characteristics of deferred Japanese students.
Computerized records of blood centers in northern Japan (Miyagi and Fukushima Prefectures) from March 2010 through March 2011 were retrospectively analyzed.
Among 231,361 individuals visiting during the 12-month period, 24,778 were students. Of these, 19,193 (77%) attempted donation, and 5,585 (23%) were deferred. Low hemoglobin, questionnaire-based interview decisions, and medication were the main reasons for temporary deferral. Age, sex, and blood center location were associated with low hemoglobin; donation history and blood center location were associated with medication-based deferral. The odds ratio among female students deferred for low hemoglobin was 35.48 with a 95% CI of 27.74-45.38.
These results suggest that continued efforts are needed to motivate deferred potential donors to return, to prevent low hemoglobin especially among females, and to review medical interview decisions, while paying close attention to regional differences.
随着日本社会老龄化程度的加深，对血液的需求不断增加，而年轻学生在献血者群体中的比例逐渐缩小。为了确保安全、可持续的血液供应，选择合适的献血者至关重要。本研究旨在评估日本学生献血者的暂缓率、暂缓原因和特征。
回顾性分析 2010 年 3 月至 2011 年 3 月日本北部（宫城县和福岛县）各血液中心的计算机记录。
在 12 个月期间，共有 231361 人到访，其中学生 24778 人。在这些学生中，19193 人（77%）尝试献血，5585 人（23%）被暂缓。血红蛋白偏低、问卷调查和用药是暂时暂缓的主要原因。年龄、性别和采血中心位置与血红蛋白偏低有关；献血史和采血中心位置与用药有关。女性学生因血红蛋白偏低而暂缓的比值比为 35.48，95%可信区间为 27.74-45.38。
这些结果表明，需要继续努力，以激励暂缓的潜在献血者返回，特别要预防女性的血红蛋白偏低，并审查医疗面谈决定，同时密切关注地区差异。
