Abstract

A card-type odor identification test called the “Open Essence (OE),” consisting of 12 types of everyday odors familiar to Japanese people, was recently developed. In this study, we calculated the cut-off value of the OE score for screening for age-related olfactory decline.

Participants aged 23 to 91 performed the OE test. After we confirmed that the OE score differed significantly between young/middle-aged adults (under 65?years old) and elderly adults (over 65?years old), we assumed that the young/middle-aged group had normal olfactory ability, whereas the elderly group had experienced a decline in odor identification ability. We then performed receiver operating characteristic (ROC) analysis using the OE score.

The cut-off value of the OE score for screening for age-related olfactory decline, calculated on the basis of the ROC curve, was 8.

Individuals with the OE scores of 7 or less may have age-related olfactory decline. Our finding suggests that this cut-off value could be used to screen Japanese people with age-related olfactory decline.

The OE test is self-administered and has a cut-off value of the OE score for screening for age-related olfactory decline. Therefore, it is expected to be useful in mass screening for elderly adults.

使用专为日本人设计的卡片式气味识别测试筛选与年龄相关的嗅觉衰退

最近开发出了一种名为“开放精华(OE)”的卡片式气味识别测试，该测试由日本人熟悉的12种日常气味组成。在这项研究中，我们计算了OE评分的临界值，用于筛查与年龄相关的嗅觉衰退。年龄在23岁到91岁之间的参与者进行了OE测试。在我们确认了年轻/中年成年人(65岁以下?老年人(65岁以上?年龄)，我们假设中青年组嗅觉能力正常，而老年组嗅觉识别能力下降。然后，我们使用OE评分进行受试者工作特征(ROC)分析。根据ROC曲线计算，OE评分用于筛查年龄相关嗅觉衰退的临界值为8。OE得分在7分或更低的个体可能有与年龄相关的嗅觉衰退。我们的发现表明，这个临界值可以用来筛选与年龄相关的嗅觉衰退的日本人。OE测试是自我管理的，OE评分有一个临界值，用于筛查与年龄相关的嗅觉衰退。因此，有望在老年人的大规模筛查中发挥作用。
