A cross-sectional study was carried out at Tianjin University campus, China, from February 21 to June 10, 2006, to survey the association between dampness in dorms, and allergy and airways infections among college students. The health and dampness conditions were self-reported by 3436 students living in 1511 dorm rooms located in 13 buildings on the campus. The buildings were selected according to their positions, construction periods and occupant densities. The symptoms involved wheezing, dry cough during night, rhinitis, eczema, cold/flu, ear inflammation, pneumonia and tuberculosis. The indoor moisture signs were mould/damp spots on walls, ceilings and floors; suspected or ever happened water damage; condensation on windowpane in winter and odours perceived by subjects themselves. There was a significant positive association between condensation and dry cough. Eczema was often reported in rooms with moisture problem. Dampness was a significant risk factor for common cold.
Dampness problems in dorms of Chinese students are a risk factor for allergic symptoms, and hence there is a need for dorm environment improvement. Health problems related to ventilation and microbiology problems in dorms should be further studied.
2006年2月21日至6月10日在中国天津大学校园进行了一项横断面研究，以调查宿舍潮湿与大学生过敏及呼吸道感染之间的关联。居住在校园内13栋楼中1511间宿舍的3436名学生自行报告了健康状况和潮湿情况。这些建筑根据其位置、建造时间和居住密度进行选择。症状包括喘息、夜间干咳、鼻炎、湿疹、感冒/流感、耳部炎症、肺炎和肺结核。室内潮湿迹象包括墙壁、天花板和地板上的霉菌/湿斑；疑似或曾发生过水损；冬季窗玻璃上的冷凝水以及受试者自身察觉到的气味。冷凝水与干咳之间存在显著的正相关。在有潮湿问题的房间里经常报告有湿疹。潮湿是普通感冒的一个重要危险因素。
中国学生宿舍的潮湿问题是过敏症状的一个危险因素，因此需要改善宿舍环境。与宿舍通风和微生物问题相关的健康问题应进一步研究。
