The aim of the present study was to evaluate taste sensitivity and sleep pattern throughout age.
Thirty-five male adults aged (25.05±0.71 years), and twenty- four older adults (68.92 ± 6.43 years) were selected and submitted to sleep evaluation (Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale), as well as taste sensitivity. Taste sensitivity was evaluated using three dilutions and the different concentrations were presented for the four basic flavors (salty, sweet, bitter and sour). These samples were encoded with three digits and randomly presented to the participants in 50 mL plastic cups.
In both groups, sleep quality was poor (PSQI >5). Older adults presented a negative effect to identify sweet and salty taste and, in this population, sleep time was associated with sweet taste perception.
We may suggest that aging may cause changes in taste sensitivity, as well as total sleep time was observed to be a significant predictor of sweet taste. Sleep may play an important role in taste sensitivity, although the mechanisms are still unknown. Thus, the results of this research may contribute to the emergence of new studies that seek to better understand this relationship of sleep quality as taste sensitivity.
本研究旨在评估不同年龄段的味觉敏感性和睡眠模式。
选取35名成年男性（年龄25.05±0.71岁）和24名老年人（年龄68.92±6.43岁），对其进行睡眠评估（匹兹堡睡眠质量指数和爱泼沃斯思睡量表）以及味觉敏感性评估。使用三种稀释度评估味觉敏感性，并针对四种基本味道（咸、甜、苦、酸）呈现不同浓度。这些样品用三位数字编码，随机装在50毫升塑料杯中提供给参与者。
两组的睡眠质量均较差（匹兹堡睡眠质量指数>5）。老年人识别甜味和咸味的能力受到负面影响，且在该人群中，睡眠时间与甜味感知相关。
我们可以推测，衰老可能导致味觉敏感性发生变化，而且总睡眠时间被观察到是甜味感知的一个重要预测因素。睡眠可能在味觉敏感性中发挥重要作用，尽管其机制尚不清楚。因此，本研究结果可能有助于开展新的研究，以更好地理解睡眠质量与味觉敏感性之间的这种关系。
