O-113 OCULAR SYMPTOMS OF SICK BUILDING SYNDROME AMONG OFFICE WORKERS AT UNIVERSITY HOSPITAL: ASSOCIATIONS WITH INDOOR AIR QUALITY

Abstract Introduction Sick Building Syndrome (SBS) represents a significant health concern associated with indoor air quality. Among the various symptoms of SBS, ocular complications stand out as a major issue, particularly within office environments. This study aims to ascertain the prevalence and associated factors of ocular complications resulting from SBS among office workers in administrative offices at an academic medical institute. Methods This cross-sectional analytical study employed a self-reporting questionnaire to assess the characteristics of workers, their working conditions, and their perceptions of the workplace environment. Additionally, the study included a building assessment conducted through a walk-through survey and indoor air quality (IAQ) measurements. Results Out of the 290 office workers surveyed, 261 individuals (90%) from 25 offices within 11 buildings participated in the study. Among these participants, 71 (27.2%) reported experiencing ocular SBS symptoms. Factors associated with ocular SBS included: Computer screen usage (a OR 1.21) High air temperature (a OR 2.20) Low relative humidity (a OR 1.67) High total variable bacteria count (a OR 1.32) Elevated CO2 levels (a OR 1.04) Increased formaldehyde levels (a OR 5.90) Discussion, Conclusion This study revealed a higher prevalence of ocular SBS compared to previous research. Beyond poor IAQ, our findings suggest that computer screen usage may exacerbate ocular SBS. To prevent ocular SBS, we recommend controlling indoor air temperatures and relative humidity. Furthermore, addressing formaldehyde sources, as well as improving indoor ventilation systems to reduce formaldehyde and CO2 levels, should be considered. Implementing proper computer screen usage practices can also help reduce the incidence of ocular SBS.
