Overall physical activity (PA) has been linked to decreased olfactory dysfunction and could improve olfactory function. Additionally, decreased olfactory function can contribute to reduced overall PA levels, given its association with neurodegenerative disorders. This study aims to examine the relationship between specific PA parameters (duration, frequency, intensity) and olfactory function in adults.
A total of 3,527 participants from the National Health and Nutrition Examination Survey (NHANES) 2013-2014 underwent assessments for weekly PA duration, frequency, and intensity, alongside a smell test (including odors such as chocolate, strawberry, grape, onion, smoke, natural gas, leather, and soap). Correlation analyses and binary logistic regressions using SPSS were used to evaluate associations.
The total smell score exhibited small yet significant positive correlations with the duration, frequency, and volume of moderate PA (correlation coefficients ranging between 0.05 and 0.08; all ≤ 0.05) and frequency of vigorous PA (correlation coefficient of 0.05; < 0.05). For moderate PA, the duration, frequency, and volume were significantly and positively associated with the ability to correctly detect the smell of grapes while the frequency was significantly and positively associated with the ability to identify smoke and leather odors (odds ratios ranging from 1.01 to 1.07; < 0.05). For vigorous PA, the frequency of PA was positively associated with the detection of grape smell (odds ratio of 1.05; < 0.05).
Some parameters of an active lifestyle are associated with improved odds of accurately identifying odors by up to 7.4%. Moderate PA duration, frequency, and volume were linked to better olfactory scores, while high-intensity PA had limited associations.
总体身体活动（PA）与嗅觉功能障碍的减少有关，并且可以改善嗅觉功能。此外，鉴于嗅觉功能下降与神经退行性疾病有关，它可能导致总体PA水平降低。本研究旨在探讨成年人特定PA参数（持续时间、频率、强度）与嗅觉功能之间的关系。
共有3527名来自2013 - 2014年国家健康与营养检查调查（NHANES）的参与者接受了每周PA持续时间、频率和强度的评估，同时还进行了嗅觉测试（包括巧克力、草莓、葡萄、洋葱、烟、天然气、皮革和肥皂等气味）。使用SPSS进行相关性分析和二元逻辑回归以评估关联。
总嗅觉评分与中等强度PA的持续时间、频率和量呈现出虽小但显著的正相关（相关系数在0.05至0.08之间；均≤0.05）以及与高强度PA的频率呈现出正相关（相关系数为0.05；<0.05）。对于中等强度PA，持续时间、频率和量与正确检测葡萄气味的能力显著正相关，而频率与识别烟和皮革气味的能力显著正相关（优势比在1.01至1.07之间；<0.05）。对于高强度PA，PA的频率与葡萄气味的检测呈正相关（优势比为1.05；<0.05）。
积极生活方式的一些参数与准确识别气味的几率提高高达7.4%相关。中等强度PA的持续时间、频率和量与更好的嗅觉评分相关，而高强度PA的关联有限。
