Abstract

Background: This study examined the association between memory function and reduced olfactory and gustatory function among independent community-dwelling older adults.

Methods: This cross-sectional study included 127 older adults (65.4% women). We assessed their memory, odor, and taste identification skills. Open essence (OE) test and taste strips (TS) were used to identify hyposmia (OE test ≤6) and hypogeusia (TS test ≤8), respectively.

Results: Participants with severe hyposmia had significantly poorer memory functions compared to participants without severe hyposmia. After adjusting for covariates, multivariate logistic regression models revealed a significant association between immediate recognition performance and a decreased likelihood of severe hyposmia (odds ratio=0.65; 95% confidence interval 0.47-0.90). We observed no significant association between taste function and memory.

Conclusion: Memory function may be associated with olfactory impairment in older adults.

居住在社区的独立老年人的嗅觉和味觉功能与记忆力的关系。

研究背景本研究探讨了独立居住在社区的老年人的记忆功能与嗅觉和味觉功能减退之间的关系：这项横断面研究包括 127 名老年人（65.4% 为女性）。我们评估了他们的记忆、气味和味觉识别能力。我们使用开放本质（OE）测试和味觉试纸（TS）分别鉴定嗅觉减退症（OE测试≤6）和味觉减退症（TS测试≤8）：结果：与没有严重嗅觉减退的参与者相比，严重嗅觉减退的参与者的记忆功能明显较差。在对共变量进行调整后，多变量逻辑回归模型显示，即时识别能力与严重嗅觉减退的可能性之间存在显著关联（几率比 = 0.65，95% 置信区间 = 0.47-0.90）。我们观察到味觉功能和记忆力之间没有明显的联系：结论：记忆功能可能与老年人的嗅觉损伤有关，但与味觉功能无关。
