This study determined the association of cold-related symptoms with workplace temperature and thermal insulation of clothing among Thai chicken industry workers. Three hundred workers were interviewed regarding cold-related symptoms, which were regressed on worksite temperature and protective clothing. In total, 80% of workers reported respiratory symptoms; 23%, cardiac symptoms; 62%, circulation disturbances; 42%, thirst; 56%, drying of the mouth; and 82%, degradation of their performance. When adjusted for personal characteristics, respiratory symptoms were 1.1‒2.2 times more prevalent at -22‒10°C than at 10‒23°C. At -22‒10°C, cardiac symptoms increased by 45%, chest pain by 91%, peripheral circulation disturbances by 25%, and drying of the mouth by 57%. Wearing protective clothing with at least 1.1 clo units was associated with marked reductions in symptom prevalence. Therefore, temperatures lower than 10°C increased prevalence of cold-related symptoms, which are largely preventable by appropriate clothing use.
本研究旨在确定与泰国家禽业工人的冷相关症状与工作场所温度和衣物热绝缘相关的因素。对 300 名工人进行了有关冷相关症状的访谈，并将其回归到工作场所温度和防护服装上。总的来说，80%的工人报告有呼吸道症状；23%有心脏症状；62%有血液循环障碍；42%口渴；56%口干；82%工作效率下降。调整个人特征后，-22-10°C 时的呼吸道症状比 10-23°C 时高出 1.1-2.2 倍。在-22-10°C 时，心脏症状增加 45%，胸痛增加 91%，外周血液循环障碍增加 25%，口干增加 57%。穿着至少 1.1 克罗单位的防护服装与显著降低症状发生率相关。因此，温度低于 10°C 会增加冷相关症状的发生率，而通过适当使用衣物可以大大预防这些症状。
