Abstract：
Metabolic rate has been used in thermophysiological models for predicting the thermal response of humans. However, only a few studies have investigated the association between an individual\'s trait-like thermal sensitivity and resting energy expenditure (REE), which resulted in inconsistent results. This study aimed to explore the association between REE and perceived thermal sensitivity. The REE of healthy adults was measured using an indirect calorimeter, and perceived thermal intolerance and sensation in the body were evaluated using a self-administered questionnaire. In total, 1567 individuals were included in the analysis (women = 68.9%, age = 41.1 ± 13.2 years, body mass index = 23.3 ± 3.3 kg/m2, REE = 1532.1 ± 362.4 kcal/d). More women had high cold intolerance (31.8%) than men (12.7%), and more men had high heat intolerance (23.6%) than women (16.1%). In contrast, more women experienced both cold (53.8%) and heat (40.6%) sensations in the body than men (cold, 29.1%; heat, 27.9%). After adjusting for age, fat-free mass, and fat mass, lower cold intolerance, higher heat intolerance, and heat sensation were associated with increased REE only in men (cold intolerance, P for trend = .001; heat intolerance, P for trend = .037; heat sensation, P = .046), whereas cold sensation was associated with decreased REE only in women (P = .023). These findings suggest a link between the perceived thermal sensitivity and REE levels in healthy individuals.
摘要：
代谢率已在热生理学模型中用于预测人类的热响应。然而,只有少数研究调查了个体的特性-如热敏感性和静息能量消耗(REE)之间的关联，这导致了不一致的结果。本研究旨在探讨REE与感知热敏感性之间的关系。使用间接热量计测量健康成年人的REE，并使用自我管理问卷评估身体的热不耐受和感觉。总的来说,1567人被纳入分析(女性=68.9%，年龄=41.1±13.2岁，体重指数=23.3±3.3kg/m2，REE=1532.1±362.4kcal/d）。更多的女性有高冷不耐受（31.8％）比男性（12.7％），与女性（16.1％）相比，男性高热耐量（23.6％）更多。相比之下,更多的女性经历了冷（53.8％）和热（40.6％）的感觉比男性（冷，29.1%；热，27.9%）。在调整了年龄之后,无脂质量，和脂肪，降低冷不耐受，较高的耐热性，热感觉仅在男性中与REE增加相关(冷不耐受，趋势P=.001；耐热性，趋势P=.037；热感，P=.046)，而冷感仅与女性的REE降低有关（P=0.023）。这些发现表明，健康个体的热敏感性与REE水平之间存在联系。
