The aim of the present study was to investigate the association between blood groups and life expectancy. We compared frequencies of ABO blood group in 269 centenarians (persons over 100 years) living in Tokyo and those in regionally matched controls (n=7153). Frequencies of blood types A, O, B, and AB in centenarians were 34.2, 28.3, 29.4, and 8.2%, respectively, while those in controls were 38.6, 30.1, 21.9, and 9.4%, respectively. Blood type B was observed more frequently in centenarians than in controls (chi(2)=8.41, P=0.04). This tendency also was true in comparison between centenarians and 118 elderly old individuals of the 7153. Approximate one-third of the centenarians were free from serious diseases such as malignancy. However, blood types were not associated with such medical records. Our findings suggest that blood type B might be associated with exceptional longevity. Responsible mechanisms need to be investigated.
本研究的目的是调查血型与预期寿命之间的关联。我们比较了居住在东京的269名百岁老人（年龄超过100岁）和地区匹配对照组（n = 7153）的ABO血型频率。百岁老人中A型、O型、B型和AB型血的频率分别为34.2%、28.3%、29.4%和8.2%，而对照组中分别为38.6%、30.1%、21.9%和9.4%。百岁老人中B型血的出现频率高于对照组（χ² = 8.41，P = 0.04）。在百岁老人与7153名中的118名老年个体的比较中，这种趋势同样存在。约三分之一的百岁老人没有恶性肿瘤等严重疾病。然而，血型与这些医疗记录无关。我们的研究结果表明，B型血可能与超长寿命有关。其相关机制有待研究。
