【摘要】 目的探讨空调清洗对人群健康可能产生的影响。方法在2012年无锡市清洗集中空调通风系统的星级宾馆中,选择两家宾馆的从业人员进行清洗前后主观感受的问卷调查分析。结果清洗前后从业人员对工作场所室内空气质量打分的满分率(χ2=21.017,P1<0.001)差异有统计学意义,清洗后满分率明显提高。在清洗后1个月上班时间皮肤干燥、瘙痒、发红症状(χ2=9.062,P1=0.003)和失眠、嗜睡(χ2=4.018,P1=0.045)的发生率显著降低,由宾馆内环境导致的鼻部刺激、鼻塞、流涕(χ2=5.546,P1=0.019)、咳嗽、咳痰、胸闷、气喘(连续性校正后χ2=4.900,P1=0.027)以及疲劳、注意力不集中(连续性校正后χ2=5.568,P1=0.018)的发生率显著降低。结论清洗后从业人员对工作场所室内空气质量的满意程度明显上升,对人群健康有一定的促进作用。更多还原
