The performance in most smell identification tests is subjected to cultural variations. This study aimed to evaluate age, gender, and smoking-related effects on the test performance in the North of Iran.
The olfactory function of 1470 eligible subjects was assessed in this study. Moreover, this study evaluated the influence of age, gender, and education on the test scores.
According to the results, females obtained higher mean test scores, compared to males (18.4 vs. 17.6). In general, the elderly obtained lower scores, and about 30% of the subjects who were ≥65 years of age had severe hyposmia or anosmia. Furthermore, the olfactory impairment frequency in smoker subjects was significantly more than non-smokers (P<0.001). Test scores were generally higher in subjects with higher education levels. Logistic regression analysis revealed that the total number of cigarette doses in smokers and age had a significant association with olfactory dysfunction (P value <0.001 and 0.004, respectively). Cronbach's α of Iran-SIT was obtained at 0.78 which was more than an acceptable value of 0.7.
The findings of this study revealed that a low score in the Iran-SIT correlated with smoking, older age, low education level, and gender (male).
在大多数嗅觉识别测试中，测试表现会受到文化差异的影响。本研究旨在评估年龄、性别和吸烟对伊朗北部嗅觉测试表现的影响。
本研究评估了1470名符合条件的受试者的嗅觉功能。此外，本研究还评估了年龄、性别和教育程度对测试分数的影响。
结果显示，女性的平均测试分数高于男性（18.4对17.6）。总体而言，老年人得分较低，约30%年龄≥65岁的受试者存在严重嗅觉减退或嗅觉丧失。此外，吸烟者的嗅觉障碍发生率显著高于非吸烟者（P<0.001）。教育程度较高的受试者测试分数通常更高。逻辑回归分析显示，吸烟者的香烟剂量总数和年龄与嗅觉功能障碍有显著关联（P值分别<0.001和0.004）。伊朗嗅觉识别测试（Iran-SIT）的Cronbach's α系数为0.78，高于可接受值0.7。
本研究结果表明，伊朗嗅觉识别测试得分低与吸烟、年龄较大、教育程度低和性别（男性）有关。
