Of a representative, racially mixed community sample of older adults in North Carolina, 59% of Whites and 49% of African Americans reported worsening memory. The complaint about memory was positively correlated with age, depressive symptomatology, and physical function but not with level of cognitive function as measured by the Short Portable Mental Status Questionnaire (SPMSQ) at baseline. In a controlled analysis of longitudinal data, initial SPMSQ score, age, African American race, lower education, depressive symptomatology, and physical deficits at baseline, but not memory complaint, predicted a decline in cognitive function as measured by the SPMSQ 3 years later. Whereas African Americans were less likely to complain of deterioration in memory, actual decline as measured by the SPMSQ was greater for African Americans than for Whites.
在北卡罗来纳州一个具有代表性的、种族混合的老年社区样本中，59%的白人及49%的非裔美国人报告记忆力变差。关于记忆力的主诉与年龄、抑郁症状及身体功能呈正相关，但与基线时通过简易便携式精神状态问卷（SPMSQ）测量的认知功能水平无关。在对纵向数据的对照分析中，初始SPMSQ得分、年龄、非裔美国人种族、低教育水平、抑郁症状及基线时的身体缺陷，而非记忆力主诉，预测了3年后通过SPMSQ测量的认知功能下降。尽管非裔美国人较少主诉记忆力变差，但通过SPMSQ测量的实际下降情况在非裔美国人中比在白人中更大。
