The prevalence of perceptions of odors and sensations of air humidity and sick building syndrome symptoms in domestic environments were studied using responses to a questionnaire on the home environment. Parents of 4530 1-8 year old children from randomly selected kindergartens in Chongqing, China participated. Stuffy odor, unpleasant odor, pungent odor, mold odor, tobacco smoke odor, humid air and dry air in the last three month (weekly or sometimes) was reported by 31.4%, 26.5%, 16.1%, 10.6%, 33.0%, 32.1% and 37.2% of the parents, respectively. The prevalence of parents' SBS symptoms (weekly or sometimes) were: 78.7% for general symptoms, 74.3% for mucosal symptoms and 47.5% for skin symptoms. Multi-nominal regression analyses for associations between odors/sensations of air humidity and SBS symptoms showed that the odds ratio for "weekly" SBS symptoms were consistently higher than for "sometimes" SBS symptoms. Living near a main road or highway, redecoration, and new furniture were risk factors for perceptions of odors and sensations of humid air and dry air. Dampness related problems (mold spots, damp stains, water damage and condensation) were all risk factors for perceptions of odors and sensations of humid air and dry air, as was the presence of cockroaches, rats, and mosquitoes/flies, use of mosquito-repellent incense and incense. Protective factors included cleaning the child's bedroom every day and frequently exposing bedding to sunshine. In conclusion, adults' perceptions of odors and sensations of humid air and dry air are related to factors of the home environment and SBS symptoms are related to odor perceptions.
本研究采用家庭环境问卷，调查了中国重庆随机选取的幼儿园 4530 名 1-8 岁儿童家长对家中气味和空气湿度的感知以及病态建筑综合征（SBS）症状的流行情况。报告显示，在过去三个月（每周或有时）中，有 31.4%、26.5%、16.1%、10.6%、33.0%、32.1%和 37.2%的家长分别报告家中存在闷臭味、异味、刺鼻味、霉味、烟味、潮湿空气和干燥空气。家长 SBS 症状（每周或有时）的流行率分别为：全身症状 78.7%、黏膜症状 74.3%和皮肤症状 47.5%。多分类回归分析显示，与空气湿度感知相关的气味与 SBS 症状之间存在关联，“每周”SBS 症状的比值比始终高于“有时”SBS 症状。居住在主要道路或高速公路附近、重新装修以及新家具是感知气味和空气湿度的危险因素。潮湿相关问题（霉斑、潮湿痕迹、水渍和冷凝）是感知空气湿度和干燥的危险因素，蟑螂、老鼠和蚊子/苍蝇的存在、使用蚊香和香薰也会增加这种风险。保护因素包括每天清洁儿童卧室并经常将被褥暴露在阳光下。总之，成年人对气味和空气湿度的感知与家庭环境因素有关，SBS 症状与气味感知有关。
