This was the first study to use cluster analysis to characterise sleep discrepancy (the discordance between self-reported and objective sleep) across multiple sleep parameters, in community-dwelling older adults. For sleep efficiency, negative discrepancy (the tendency to self-report worse sleep than objectively-measured) was associated with poorer memory, independent of insomnia severity, depressive symptoms and objective sleep. This suggests a unique role for sleep discrepancy as a possible risk factor for future cognitive decline, and warrants the need for further research.
这是第一项使用聚类分析来描述社区居住的老年人多个睡眠参数的睡眠差异（自我报告的睡眠与客观睡眠之间的不一致）的研究。对于睡眠效率，负差异（自我报告的睡眠比客观测量的更差的倾向）与较差的记忆力相关，与失眠严重程度、抑郁症状和客观睡眠无关。这表明睡眠差异作为未来认知能力下降的一个可能风险因素具有独特作用，并有必要进行进一步研究。
