This study addressed two questions: (1) Is age at migration associated with cognitive function among Chinese older immigrants? and (2) what personal and environmental factors confound the above relationship? Data were derived from the Population Study of Chinese Elderly ( = 2957). Quantile and linear regressions were used to examine the associations between age at migration and Mini-Mental State Examination (MMSE) and global cognitive function, respectively. Migration in late middle age (50-64) or late adulthood (65 or older) was associated with lower MMSE scores. Global cognition did not vary by age at migration. Associations between age at migration and MMSE were stronger among individuals with lower education or social engagement. Migrating late in one's life has important implications for cognitive health over the life course. Findings are helpful to identify vulnerable older immigrant segments and provide tailored interventions to promote their cognitive health.
（1）移民年龄是否与中国老年移民的认知功能有关？（2）哪些个人和环境因素会混淆上述关系？数据来源于中国老年人人口研究（n=2957）。采用分位数回归和线性回归分别检验了移民年龄与简易精神状态检查（MMSE）和总体认知功能之间的关系。中年后期（50-64 岁）或老年后期（65 岁及以上）移民与 MMSE 得分较低相关。而总体认知功能则不受移民年龄的影响。在受教育程度或社会参与度较低的个体中，移民年龄与 MMSE 之间的关联更为显著。在人生的后期进行移民对认知健康具有重要影响。这些发现有助于确定易受影响的老年移民群体，并提供有针对性的干预措施，以促进他们的认知健康。
