Little is known about risk factors for sick building symptoms (SBS) among health care workers (HCWs) who often face the workload, exposure to chemicals, and biological contaminants in the workplace. This study aims to evaluate the correlation between SBS and the symptoms among HCWs.
A total of 207 HCWs were recruited in a large hospital-based cross-sectional survey between March and June 2017, southern Vietnam. Face-to-face interviews were conducted for collecting data on demographics, SBS-related symptoms, working environments, and conditions. Indoor environmental conditions were measured. SBS scores, ranging from 0 to 24, were determined by a sum of the scores of general symptoms, mucosal irritation, and skin symptoms; multivariate regression analyses and the Lindeman, Merenda, and Gold (LMG) test were used to investigate the predictors and its impact on the SBS Results: A mean SBS score was 9.7 (range: 1-21). Compared with males, females were more likely to report higher SBS scores (10.2 vs. 7.9, p < 0.001). Being female, atopy, varying temperature room, stuffy "bad" air dust, and dirt had higher SBS scores of 2.0; 1.8; 1.7; 1.9; 3.8, respectively. LMG test showed that dust and dirt, and stuffy "bad" air were the predominant risk factors for SBS.
Our study reveals that working conditions are important and significantly associated with SBS. Taken together with our findings, the working condition criteria approach trained for architects, builders, owners, and maintenance of the building is highly recommended for indoor air quality improvement. Furthermore, larger-sample studies about working condition are urgently needed to better manage SBS.
医护人员（HCWs）经常面临工作负荷、接触化学物质和生物污染物等问题，因此他们患病态建筑综合征（SBS）的风险因素知之甚少。本研究旨在评估 SBS 与 HCWs 症状之间的相关性。
2017 年 3 月至 6 月，在越南南部的一家大型医院进行了一项基于横断面的调查，共招募了 207 名 HCWs。通过面对面访谈收集人口统计学、SBS 相关症状、工作环境和条件等数据。测量室内环境条件。SBS 评分范围为 0 至 24 分，由一般症状、黏膜刺激和皮肤症状得分总和确定；采用多元回归分析和林德曼、梅伦达、戈尔德（LMG）检验来探讨预测因素及其对 SBS 的影响。
平均 SBS 得分为 9.7（范围：1-21）。与男性相比，女性更有可能报告更高的 SBS 得分（10.2 比 7.9，p<0.001）。女性、特应性、温度变化的房间、闷热的“差”空气灰尘和污垢与更高的 SBS 得分 2.0；1.8；1.7；1.9；3.8 相关。LMG 检验表明，灰尘和污垢以及闷热的“差”空气是 SBS 的主要危险因素。
我们的研究表明，工作条件很重要，与 SBS 显著相关。综上所述，建议为改善室内空气质量，对建筑的建筑师、建筑商、业主和维护人员进行工作条件标准培训。此外，还需要进行更大规模的工作条件研究，以更好地管理 SBS。
