This cross-sectional study measured taste and smell perception using intensity and hedonic ratings to two olfactory (i.e., vanillin, methional) and two gustatory stimuli (i.e., sucrose, monosodium glutamate), representing sweet and savoury flavours. Detection sensitivities to sucrose and vanillin were also assessed using a forced choice detection paradigm aligned with the signal detection framework. MANCOVAs were employed to compare sensory perception between groups based on vaping use frequency. Additional regression analyses were conducted to identify potential predictors of intensity and hedonic sensory ratings.
Participants were recruited from the University of Otago student population and surrounding neighbourhoods of Dunedin, New Zealand in 2023.
The study included 213 university students (98 vapers and 115 non-vapers) RESULTS: We found a significant difference in hedonic ratings for vanillin, indicating a stronger preference among non-vapers. However, no other differences between the two groups were significant. Notably, the use of tobacco and mint flavours were emerged as significant predictors for hedonic responses to the savoury smell and sweet taste stimulus, respectively. No significant differences were observed between groups in the ability to detect weak stimuli.
Our findings suggest that vape use, particularly with specific flavours, may be associated with alterations in hedonic responses to smells. This finding may have potential implications for how vaping affects on food preferences and dietary choices.
方法:这项横断面研究使用强度和享乐等级对两种嗅觉(即,香兰素,甲基)和两种味觉刺激(即,蔗糖,味精),代表甜味和咸味。还使用与信号检测框架一致的强制选择检测范例来评估对蔗糖和香草醛的检测敏感性。使用MANCOVA来比较基于vaping使用频率的组间感觉知觉。进行了其他回归分析,以确定强度和享乐感觉等级的潜在预测因子。
方法:参与者来自奥塔哥大学的学生群体和达尼丁周围的社区,2023年新西兰。
方法:该研究包括213名大学生(98个vapers和115个非vapers)结果:我们发现香草醛的享乐主义评分之间存在显着差异,在非vapers中更喜欢,但没有其他显著差异。烟草和薄荷口味的使用是喜欢咸味和甜味的重要预测因素,分别。在检测弱刺激的能力方面,组间没有观察到显着差异。
结论:我们的研究结果表明,使用vape,特别是某些口味,可能与气味享乐喜好的变化有关。这一发现可能对vaping对食物偏好和饮食选择的影响有潜在的影响。
