Abstract

Several studies evaluated the influence of cultural components on the Sniffin’ Sticks Identification Test in different countries. The aim of this study was to analyze the olfactory function in a large sample of healthy subjects living in Sardinia, an island known for its historic genetic isolation, in relation to different age ranges to provide new data in healthy Sardinian subjects.

Olfactory perception of 161 participants (108 females and 53 males; age range 19–78?years) was assessed through three different parameters: odor detection threshold, discrimination, and identification by means of the Sniffin’Sticks Extended test (SST).

Our results show that young adults were generally normosmic, while in subjects over 55, a statistically significant age-related decrease of all the parameters was observed. Regarding odor identification task, a few, such as leather, apples, lemons, cloves, and pineapples, were frequently incorrectly identified by participants probably due to the similarities between the odors and distractors.

Our data provide a comprehensive evaluation of the three olfactory components in the Sardinian population and confirm a decrease in the odor detection threshold, discrimination and identification as well as in the global TDI score in subjects over 55?years of age. These results may be useful in providing normative values for routine clinical use of the SSET in Sardinian subjects.

嗅觉功能和年龄:在撒丁岛进行的嗅探棒扩展测试研究

一些研究评估了文化因素对不同国家嗅棒识别测试的影响。本研究的目的是分析生活在撒丁岛(一个以其历史上的遗传隔离而闻名的岛屿)的大量健康受试者的嗅觉功能样本与不同年龄范围的关系，以提供撒丁岛健康受试者的新数据。161名参与者(女性108人，男性53人)的嗅觉知觉;年龄范围19-78岁)通过三个不同的参数进行评估:气味检测阈值、辨别和通过嗅探棒扩展试验(SST)识别。我们的研究结果显示，年轻人通常是正常的，而在55岁以上的受试者中，所有参数都有统计学上显著的年龄相关下降。在气味识别任务中，皮革、苹果、柠檬、丁香和菠萝等少数气味经常被参与者错误识别，这可能是由于气味和干扰物之间的相似性。我们的数据对撒丁岛人口的三种嗅觉成分进行了全面评估，并证实了55岁以上受试者的气味检测阈值、歧视和识别以及全球TDI评分的下降。年龄。这些结果可能有助于为撒丁岛受试者的常规临床使用SSET提供规范性值。
