Abstract
Introduction: Indoor air quality (IAQ) is a state of the air quality inside a building that is related to the health and comfort of the building's occupants which often cause sick building syndrome (SBS), acute health and comfort consequences that related to time spent in building. Psychosocial factors, including human behavior, emotions, and interactions, are also linked to SBS. Objectives: To determine the association between indoor air quality (IAQ) and psychosocial factors related to sick building syndrome among office workers in old and new building of Penang Governmental Administrative Office Methodology: The study design used was comparative cross- sectional study which it involved 186 workers old and new buildings. The questionnaire modified from Industry Code of Practice on Indoor Air Quality 2010, NIOSH Indoor Environmental Quality Survey 1991 and Copenhagen Psychosocial Questionnaire (COSPOQ III) were used to obtain information on sociodemographics, office characteristics, Sick Building Syndrome (SBS) symptoms, and psychosocial factors. The IAQ parameters and thermal comfort were measured using instruments of IAQ and thermal comfort. Results and Discussion: There were significant differences in chemical parameters which were formaldehyde (Z= -4.028, p= <0.001), TVOC (Z= -9.573, p= <0.001), PM10 (Z= -12.466, p= <0.001), PM2.5 (Z= -13.513, p=<0.001), and ozone (Z= -14.843, p= <0.001) between old and new buildings. All physical parameters which were air velocity (Z= -3.744, p=<0.001), relative humidity (Z=-3.256, p=<0.001) and temperature (Z=-3.924, p=<0.001) have significant differences. Thermal comfort condition in both buildings were considered neutral and comfortable. For psychosocial factors, one domain had significant difference between both buildings which was demands of work (χ2 = 13.96, p < 0.001). Cough was the only symptoms that had significant difference (χ2= 5.70, p= 0.017) between both buildings. In old building, variables that have associated with SBS were formaldehyde (OR=5.22, CI=1.05-26.10), PM10 (OR=5.05, CI=1.29- 19.78), PM2.5 (OR=11.09, CI=2.19-56.29), Demands at Work (OR=5.49, CI=1.10- 27.43) and Personality (OR=13.47, CI=2.64-68.90) while in new building, the variables were PM2.5 (OR=9.08, CI=1.07-77.09), ozone (OR=4.97, CI=1.95-26.12) and personality (OR=6.67, CI=1.49-30.69). After controlling the confounders, the main predictor of SBS in old building were PM10 (OR=5.60, CI= 1.16-27.01), PM2.5 (OR=10.74, CI= 1.82-63.43) and personality (OR= 14.44, CI=2.40-86.88) while in new building was PM2.5 (OR=11.51, CI= 1.14-116.51). Comprehending these complex mechanism reveals the interaction of indoor air quality, psychosocial factors, and the occurrence of SBS.Conclusion: The prevalence of SBS among office workers was influenced by both indoor air quality and psychosocial factors. Old building tend to have a more significant impact on SBS compared to new ones. A mitigation plan and proactive measures are essential to improve indoor air quality and psychosocial well-being in the workplace. This initiative aims to create a conducive environment that prioritizes the health and productivity of workers. Keywords: Indoor air quality, psychosocial factors, sick building syndrome, age of building, office workers
