摘要

Since the early 1970s, building-related symptoms (BRSs) have emerged as an occupational and environmental health issue. We previously conducted three phase studies with two cross-sectional studies using questionnaires and environmental measurements and one longitudinal study to investigate the environmental factors associated with the BRSs. Maintenance of office environment may differ based on the total floor area of a building. Based on our previous studies, we conducted a cross-sectional study concerning the effects of the total floor area of a building on the BRSs, particularly in air-conditioned office buildings. The surveys were conducted from January 2018 to March 2012, involving 216 offices and 1891 employees during the winter season. We administered questionnaires to these employees for obtaining information on BRSs, indoor air quality (IAQ), workplace environment perceptions, and occupational stress. The office buildings were categorized into small buildings (<2000 m2, 93 offices with 654 employees), middle buildings (2000-3000 m2, 22 offices with 293 employees), and large buildings (>3000 m2, 101 offices with 944 employees) according to the total floor area of the buildings. The complaints of indoor temperature and humidity were significantly lesser in small buildings compared with large buildings. Multivariate analysis revealed that upper respiratory symptoms, although their associations with the buildings were not strong, were significantly lesser in small buildings compared with large buildings (for trend, p < 0.05). The BRSs for which the associations with the buildings were strong were not significantly associated with the total floor area of the buildings, although the overall prevalence of BRSs was reduced for small buildings compared with large buildings. In the three categories of buildings, indoor thermal comfort and dryness were significantly associated with strong BRSs. This study suggests that adequate maintenance of office environment and control of IAQ are particularly crucial in large buildings.
