为了比较68岁及以上的日本人和美国人的认知表现，使用两项具有全国代表性的研究，并检查是否可以通过危险因素分布的差异或其与认知表现的关联来解释差异。研究对象：1953名日本成年人和2959名美国成年人，年龄在68岁以上。方法：采用即时和延迟单词回忆以及连续7秒来测量情景记忆和算术工作记忆。结果：美国人的情景记忆得分高于日本人（20分制中的0.72分）;然而，当控制教育时，美国人和日本人没有差异。日本人的工作记忆水平（5分制为0.36分）高于美国人，教育对工作记忆的影响在美国人中比日本人强。有超过85 years. CONCLUSION年龄的差异很大，即使在教育程度和教育对认知功能的强烈影响，在美国和日本之间的认知功能的整体差异是温和的。健康差异似乎对认知的国家差异影响不大。J Am Geriatr Soc 68：354-361，2020
OBJECTIVETo compare cognitive performance among Japanese and American persons, aged 68 years and older, using two nationally representative studies and to examine whether differences can be explained by differences in the distribution of risk factors or in their association with cognitive performance.DESIGNNationally representative studies with harmonized collection of data on cognitive functioning.SETTINGNihon University Japanese Longitudinal Study of Aging and the US Health and Retirement Study.PARTICIPANTSA total of 1953 Japanese adults and 2959 US adults, aged 68 years or older.MEASUREMENTSEpisodic memory and arithmetic working memory are measured using immediate and delayed word recall and serial 7s.RESULTSAmericans have higher scores on episodic memory than Japanese people (0.72 points on a 20‐point scale); however, when education is controlled, American and Japanese people did not differ. Level of working memory was higher in Japan (0.36 on a 5‐point scale) than in the United States, and the effect of education on working memory was stronger among Americans than Japanese people. There are no differences over the age of 85 years.CONCLUSIONEven with large differences in educational attainment and a strong effect of education on cognitive functioning, the overall differences in cognitive functioning between the United States and Japan are modest. Differences in health appear to have little effect on national differences in cognition.J Am Geriatr Soc 68:354–361, 2020
