Abstract


In educational facilities, good and healthy indoor air quality is critical. This micro-environment is critical in maintaining student focus and ensuring that academic activities are carried out efficiently. The goal of this study was to see if there was a link between indoor exposure to airborne contaminants and physical characteristics and sick building syndrome and health complaints among educational building inhabitants. A cross-section of epidemiological study from 513 building occupants was selected to participate in this study. The researchers employed a modified questionnaire from the Malaysian Department of Occupational Health and Safety (DOSH) (MM040Na Questionnaire). The tenants' workspaces were monitored for indoor air quality. The score differences between environmental factors were determined using statistical analyses incorporating test differences, such as Chi – Square, T-Test, and non-parametric analysis. Logistic regression was conducted to evaluate relationship between exposure and occupants’ complaint. Results show that some indoor air pollutants (carbon dioxide, formaldehyde, and particulate matter) are related to overall sick building syndrome (Odd Ratio, OR=1.348, 2.493, 1.958 respectively). General score of SBS shows significant relationship with Air Motion (OR=2.220) and Air Flow (OR=2.515). Mucosal score of SBS suggest exposure risk towards indoor factors namely Formaldehyde (OR=2.799), while Dermal effect was derived from the exposure of Particulate (OR=2.88), Carbon Dioxide (OR=4.000), and Air Flow (OR=2.679). Conclusion: In educational environments, contaminants (total volatile organic compounds, formaldehyde, and particulate matter) as well as physical stressors (air flow, relative humidity, and ventilation) have an impact on reported symptoms.
