Abstract

The extent of hearing loss requiring hearing aid (HA) to prevent cognitive decline is unclear; we assessed this post-midlife along with the relationship between hearing thresholds and cognitive function in those who had never used HA (non-users) or used HAs for >3 years (long-term users). This study comprised 117 individuals ≥55 years with an average hearing threshold of ≥25 dB HL in their better ear and 55 of the non-users and 62 of the long-term users. The Mini-Mental State Examination, the Symbol Digit Modalities Test (SDMT), and pure-tone and sound-field audiometry were assessed. Mean ± SD hearing levels of the non-user and long-term user group were 40.83 ± 8.16 and 51.13 ± 14.80 dB HL. Non-users showed a significant association (P = 0.01) between the hearing thresholds and SDMT scores, with a cutoff value of above 38.75 dB HL identified as affecting cognitive function. There were no significant associations for long-term users.

目前还不清楚需要助听器（HA）来防止认知功能衰退的听力损失程度；我们对从未使用过助听器（非使用者）或使用助听器超过 3 年（长期使用者）的中年以后的听力损失以及听阈与认知功能之间的关系进行了评估。这项研究包括 117 名年龄≥55 岁、较好耳朵的平均听阈≥25 dB HL 的人，其中 55 人不使用助听器，62 人长期使用助听器。研究人员进行了小型精神状态检查、符号数字模型测试（SDMT）、纯音和声场测听。非使用者和长期使用者组的听力水平平均值（± SD）分别为 40.83 ± 8.16 和 51.13 ± 14.80 dB HL。非用户组的听力阈值与 SDMT 分数之间存在明显关联（P = 0.01），其中高于 38.75 dB HL 的临界值被认为会影响认知功能。长期使用者的听力阈值与 SDMT 分数无明显关联。
