Prevalence of Sick Building Syndrome Symptoms in Residents During the COVID-19 Pandemic—A Case Study of Suzhou City, China

Quarantine policies during the coronavirus disease 2019 (COVID-19) pandemic prolonged time spent at home, leading to an unintended occurrence of sick building syndrome (SBS) symptoms. The aim of this study was to investigate the prevalence of SBS symptoms among residents in Suzhou, China, during the COVID-19 pandemic. A questionnaire survey was conducted online from February to May 2022. A total of 442 adults were included in this study. The prevalence of SBS symptoms was much higher during the COVID-19 pandemic, and the proportions of general, mucosal, and skin symptoms were 59.3%, 45.5% and 49.1%, respectively. The influences of building characteristics, occupant lifestyle, indoor environment and perception of indoor environment were analysed using a multivariate logistic regression model. Neighbourhood pollutant sources, older residences, non-ownership and humidity indicators were significant risk factors for SBS symptoms. Frequent use of air fresheners was significantly associated with general (adjusted odds ratio (AOR): 4.9, 95% confidence interval (CI: 2.4–10.0), mucosal (AOR: 5.3, 95% CI: 2.4–11.5), and skin symptoms (AOR: 4.6, 95% CI: 1.6–13.1), while the use of disinfectants was significantly correlated with skin symptoms (AOR: 4.0, 95% CI: 1.5–10.7). Residents’ perception of an uncomfortable indoor environment was a significant predictor of general (AOR: 2.2, 95% CI: 1.2–4.0) and mucosal symptoms (AOR: 3.1, 95% CI: 1.6–6.0). The use of air cleaners can reduce the prevalence of general symptoms. An important finding of this study is that the psychological impact of staying at home for a long time was associated with general symptoms (AOR: 1.3, 95% CI: 1.1–1.7), which means that attention should also be paid to the mental health of residents during the COVID-19 pandemic. Although the quarantine period has now ended, our results can still serve as a reference for the impact of the indoor environment on the health of people with SBS, especially for those who stay at home for a long time, such as the elderly.

Sick Building Syndrome Overview- UK’S Indoor Sick Building Syndrome Formation Analysis

Building-related illnesses pose a critical risk to public health and have consistently been a source of concern. The illnesses are collectively referred to as Sick Building Syndrome (SBS) and are used to elaborate on a situation in which the occupants of a house experience headaches discomfort-related effects or symptoms of air borne diseases that seems to be connected to the time spent in houses. Symptoms are many, but in general, occupants may experience throat, eye, and nose discomfort, as well as fatigue and, on occasion, dizziness. The increased prevalence of this syndrome has prompted substantial research. Although there is no known specific cause of SBS, some experts have concluded that indoor pollutants have a significant role in exacerbating the illness. The sources of indoor pollutants include biological contaminants, chemical contaminants, and particulate matter. These contaminants include bacteria, volatile organic compounds (VOCs), and dust, respectively. This study will examine the role of indoor pollutants in Sick Building Syndrome symptoms, investigate the causes and effects, and recent progress in understanding and controlling SBS caused by these contaminants.And also outlines an overview of the UK’s SBS issues.

Hierarchical and two-step clustering to assess symptoms of sick building syndrome in office spaces in an educational building

ABSTRACT People spend a significant amount of time indoors, being exposed to situations that might lead to discomfort, illness and loss of productivity. This study addressed the symptoms reported by employees of office spaces within an educational building, focusing on sick building syndrome (SBS), a set of symptoms experienced by occupants of buildings without a known cause. Volunteers were asked to complete a questionnaire reporting their symptoms during the workday. After data collection, hierarchical and two-step clustering were applied to assess the symptoms reported. The main results found were: (I) around 43.06% of people reported at least one symptom of SBS; (II) two-step clustering analysis showed that the main predictive symptoms are blurred vision, eye irritation, exhaustion, drowsiness and weakness; (III) hierarchical clustering analysis observed a high probability of simultaneous symptoms such as exhaustion and drowsiness, nasal irritation or itching and runny nose. At the same time, cough and shortness of breath showed a lower probability; (IV) the dendrogram formed a group predominantly linked to respiratory symptoms and another related to throat and skin symptoms; (V) the application of cluster analysis has the potential to describe the patterns and groups of identified symptoms accurately. Additionally, the research presented several contributions, such as identifying the most severe symptoms requiring immediate mitigation actions and enabling decisions related to employees’ health and well-being by implementing preventive measures to promote a healthier environment.

Indoor air quality and sick building syndrome symptoms in administrative office at public university

Sick Building Syndrome (SBS) is an illness among workers linked to time spent in a building. This study aimed to investigate the Indoor Air Quality (IAQ) and symptoms of Sick Building Syndrome (SBS) among administrative office workers. The IAQ parameters consist of ventilation performance indicators, and physical and chemical parameters were measured using specified instruments for three days during weekdays. The SBS symptoms were assessed by a questionnaire adopted from the Industry Code of Practice of Indoor Air Quality (ICOP-IAQ) 2010 among 19 employees from the office in East Coast Malaysia. Relationship between past symptoms and present symptoms which are draught (past symptoms) with feeling heavy headed (present symptoms) (r = 0.559, p < 0.05), room temperature too high (past symptoms) was highly correlated with feeling heavy headed (present symptoms) (r = 0.598, p < 0.01) and cough (present symptoms) (r = 0.596, p < 0.01). Room temperature (past symptoms) has a positive medium relationship with cough (present symptoms) (r = 0.477, p < 0.05) and scaling itching scalp or ears (present symptoms) has a relationship between stuffy bad air (r = 0.475, p < 0.05) and dry air (r = 0.536, p < 0.05). There was a significant association between RH with drowsiness (χ2 = 7.090, p = 0.049) and dizziness (χ2 = 7.090, p = 0.049). The association was found between temperature and SBS symptoms between temperature with headache (χ2 = 7.574, p = 0.051), feeling heavy-headed (χ2 = 8.090, p = 0.046), and skin rash itchiness (χ2 = 7.451, p = 0.044). Air movement also showed a positive association with symptoms of feeling heavy-headed (x2 = 8.726, p = 0.021). PM10 has positive significance with SBSS which are feeling heavy-headed (χ2 = 7.980, p = 0.023), and eyer's irritation (χ2 = 7.419, p = 0.038). The conclusion of this study showed that there were positive significant between temperature and relative humidity toward SBSS.

Comparing classic regression with credit scorecard model for predicting sick building syndrome risk: A machine learning perspective in environmental assessment

Quarantine policy for COVID-19 control brings outdoor risks to indoor, leading to unintended exposure to sick building syndrome (SBS) symptoms. The aim of this study was to establish a comparative framework for the application of multiple logistic regression (classic regression) and credit scorecard models based on Logistic Regression (logit) and Decision Tree (DT) models in predicting the risk of developing SBS among citizens of Alborz province in Iran. The results of the classic regression indicated that the number of residents in the home (OR = 1.127, 95% CI: 1.017–1.760), were shown to have a significant association with total SBS symptoms. In the credit scorecard model utilizing the logit model, the variable with the greatest predictive significance for total SBS as well as general, and mucosal symptoms was work status. Furthermore, in the credit scorecard model based on DT model, the levels of PM2.5 and PM10, were the most significant predictors for the total SBS and dermal symptoms, respectively. As such, ozone (O3) emerged as the most influential factor in predicting both general and mucosal symptoms. As credit scoring, the greatest base score (109.86) was associated with mucosal symptoms, while the lowest base score (82.10) was associated with general symptoms. In conclusion, the DT model exhibited superior performance as a scoring model compared to the logit model and classic regression, as evidenced by its higher performance indexes. As such, only dermal symptoms exhibited mean scores higher than the base scores, suggesting that the overall quality of the indoor environments was generally poor.

Sick Building Syndrome (SBS): A Proactive Mitigation Strategy Focused on University Office Buildings in the United Kingdom

Since most people spend more time at work in recent times, this has led to more workplace issues and health problems. The well‐being of occupants and their overall health are strongly impacted by factors that determine the standard of indoor environments. These factors include the air quality, the level of thermal comfort, the inclusion of indoor plants, the admission of daylighting, and a variety of other factors. The absence of any of these may result in sick building syndrome (SBS). Therefore, well‐planned indoor workspaces are vital for occupants’ health and productivity at work. The aim of this article is to investigate proactive measures for mitigating SBS in office buildings located within universities in the United Kingdom. The study administered a questionnaire to gather perceptions of office occupants, followed by a comparative case study analysis of two office buildings at the University of Greenwich located on different campuses to highlight the correlation among the physical parameters of indoor office spaces and the occurrence of SBS. The results showed that a notable percentage of participants reported experiencing at least two symptoms of SBS. This study provided clear evidence that symptoms of SBS are primarily associated with the physical characteristics of the building, and these elements significantly influence the occupants’ experiences. The mitigation of potential adverse effects on the well‐being of inhabitants during the operating phase of a building resulting from physical variables can be achieved by the implementation of conscious design considerations during the initial planning stages of future buildings. One of the practical implications of this study is that it raises the urgency for built environment professionals to be fully aware of how their design decisions could either contribute to or prevent SBS symptoms.

Assessment of the Air Cleaning Performance and Humidity and Temperature Control by Five Evergreen Woody Plants

Indoor air quality (IAQ) directly affects human health. The increase in PM and CO2 concentration indoors caused an increase in the prevalence of sick building syndrome (SBS) symptoms. Plants could contribute to reducing particulate matter (PM) and CO2. This study identifies the most efficient evergreen plant species for improving indoor air quality by assessing the ability of five different indigenous Korean evergreen plant species to reduce PM and CO2 and regulate humidity and temperature under indoor environmental conditions in acrylic chambers. The clean air delivery rates (CADR) were calculated to evaluate the efficacy of plants in reducing PM and CO2. We assessed the performance of removing the five study plants on PM1 (~0.68–3.01 m3/h/leaf area), PM2.5 (~0.73–3.08 m3/h/leaf area), PM10 (~0.67–3.04 m3/h/leaf area), and CO2 (~0.48–1.04 m3/h/leaf area). The species Ilex pedunculosa, Pittosporum tobira, and Gardenia jasminoides were the most effective at reducing PM. The CADR of CO2 also differed among the five plant species and corresponded to their photosynthetic rate. Viburnum odoratissimum var. awabuki, which had the high photosynthetic rate, was most effective at reducing CO2. By contrast, PM reduction was correlated with plant leaf structure. Plants with a high leaf density can accumulate more PM. The plants were also able to control temperature and humidity. The average temperature of the control chamber was higher, and the humidity was lower than that of the plant chambers. In this study, the five evergreen species effectively reduced air pollutants and can be used to improve IAQ.

Association Between Air Microbiological Exposure With Sick Building Syndrome (SBS) among College Dormitory Students in Public University

Introduction: Microbiological pollutants in indoor air can lead to sick building syndrome (SBS). A conducive academic environment in university dormitories requires healthy indoor air quality to enhance student performance. This study aimed to determine the association between indoor air microbiological exposure and SBS among college dormitory students at a public university. Methods: A cross-sectional study was conducted among 112 male and female college dormitory students who stayed in the public university dormitory for more than three months. Respondents were given a self-administered questionnaire-based NIOSH Indoor Environmental Quality Survey. 14 houses were selected for the measurement of indoor air quality which included PM2.5, PM10, relative humidity (%), temperature (°C), air velocity (m/s), indoor bacterial concentration (cfu/m3), and indoor mould concentration (cfu/m3). Results: Higher percentages of SBS symptoms were reported among female (94.6%) college dormitory students compared to male (82.1%). A significant difference in itching symptom on the arms and forearms was found among individuals of different genders (p&lt;0.05). Indoor air parameters such as temperature (OR = 2.56, 95% CI = 2.66-9.87), relative humidity (OR = 1.77, 95% CI = 1.54 – 5.79), indoor bacteria concentration (OR=2.28, 95% CI = 2.48 – 10.93), and indoor mould concentration (OR=2.59, 95% CI = 1.75 – 8.98) were significantly associated with the recent SBS symptoms. Multiple logistic regression showed that the most significant predictor of SBS was indoor mould concentration. Conclusion: Exposure to high concentrations of indoor bacteria and mould, high temperatures, and high relative humidity influenced the prevalence of SBS among college dormitory students. Further assessment and preventive action need to be taken to reduce the exposure of indoor air microbiological to the students.

Home environment exposure and sick building syndrome (SBS) symptoms among adults in southern China: Health associations in 2010 and 2019

We studied time trends in home environment and sick building syndrome (SBS) symptoms in a repeat study in five cities in southern China. Moreover, we studied associations between home environment exposure and SBS symptoms. Parents from randomly selected day care centers were invited. One parent per family answered a questionnaire on the home environment and their own SBS symptoms. Data collection was performed in two surveys in 2010 and 2019 (27,292 participants in 2010 and 32,073 in 2019). We used two-level logistic regression to analyze health associations. Asthma decreased from 1.7% to 1.5% (P < 0.05) but allergic rhinitis increased from 6.5% to 16.4% (P < 0.001). All SBS symptoms decreased from 2010 to 2019 (all P < 0.001). Most aspects of the home environment improved from 2010 to 2019 but there were less cleaning, more cats, dogs, and urbanization in 2019. Redecoration, new furniture, and pests were associated with most types of SBS symptoms, similarly in 2010 and 2019. Environmental tobacco smoke (ETS) was associated with SBS symptoms in 2019 only. In conclusion, prevalence of SBS symptoms among young parents in southern China decreased from 2010 to 2019 but allergic rhinitis increased. Cockroaches, rats, mice, mosquitoes or flies can be consistent biological risk factors for SBS symptoms. Redecoration, buying new furniture and traffic air pollution are other risk factors for SBS symptoms. Daily cleaning, frequently putting bedding to sunshine, and having a fan in the bathroom can be protective factors. ETS is an emerging risk factor for SBS symptoms.

Estimating perceived indoor air quality and environmental satisfaction using a camera

Although indoor environmental monitoring data are increasingly available, they often fail to accurately capture personal environmental perception, comfort, and satisfaction. This disconnection has led to a growing interest in using real-time feedback from building users to improve the control of heating, ventilation, and air-conditioning systems and reduce energy waste. However, traditional questionnaire-based surveys only provide a snapshot at the time of investigation and suffer from a variety of bias sources. To address this, this paper proposes a novel camera-based method for estimating perceived indoor air quality and environmental satisfaction by analysing facial expressions. We conducted indoor air pollution exposure experiments on 24 healthy adults in twin environmental chambers. Their changes in facial expressions were compared between different exposure conditions and the potential correlation between facial expressions and perceived air quality, environmental satisfaction, and self-reported sick building syndrome symptoms was explored. Preliminary results indicate that a common RGB camera can repeatably detect facial expressions from the same subject. Also, results from a subset of five subjects suggest moderate differences in concentration, calmness, contemplation, and tiredness expressions between the two air quality conditions.

Dampness and mould in Chinese homes and sick building syndrome (SBS) symptoms – Associations with climate, family size, cleaning and ventilation

We investigated associations between dampness in Chinese homes and sick building syndrome (SBS) symptoms and studied the role of climate, family size, cleaning and ventilation for dampness, mould and SBS. A questionnaire survey was done in 2019–2020 among adults in five cities (32349 participants) and data on outdoor climate was collected. Multilevel logistic regression was used to calculate adjusted odds ratios (ORs). In total, 2.2% had rhinitis, 1.8% eye, 1.6% throat and 2.9% skin symptoms, 2.1% headache and 8.7% fatigue (weekly symptoms). Overall, 12.1% reported indoor mould, 5.7% damp bedding, 5.3% mould odour and 33.8% humid air in current home. Mould was associated with all symptoms (ORs 1.86–2.15 for minor mold growth and 1.65–3.45 for major mould growth). Damp bedding was associated with all symptoms (ORs 2.18–2.80 for minor dampness and 2.51–8.03 for major dampness). Mould odour was associated with all symptoms (ORs 1.84–2.77 for sometimes odour and ORs 3.78–7.80 for weekly odour). Perception of humid air was associated with all symptoms. ORs increased by number of dampness signs. Precipitation, outdoor relative air humidity and temperature increased dampness, mould and SBS symptoms. Large family size increased dermal symptoms. Daily floor cleaning, airing in winter, putting bedding to sunshine and mechanical ventilation in the bathroom reduced dampness, mould and SBS symptoms. In conclusion, mould and dampness in Chinese homes can increase rhinitis and SBS-symptoms in a dose-response manner. A warmer and more humid climate can increase, and cleaning and ventilation in the home can decrease dampness, mould and SBS symptoms.

The Implications of Sick Building Syndrome (SBS) on Students’ Productivity in Hostel Buildings

In recent years, sick building syndrome (SBS) has emerged as a major issue across Asia. The aim of this study is to investigate associations between the SBS and its implication towards students' well-being and productivity in four (4) hostel buildings in Taiping, Perak. Four hundred (n = 400) questionnaires were distributed on purpose to the students as part of a quantitative research design. The most significant effect of Sick Building Syndrome on pupils is a disruption of their ability to concentrate in the classroom. Symptoms such as fatigue and drowsiness, dizziness, sore throat, and dryness are the most common ones that students experience when residing in hostels. Totally, 61% reported being unable to concentrate on their studies, 38% are unhealthy and inactive in the hostel, and 19% do not get enough sleep. This research is important for students, researchers, educational institutions, and society as it addresses the prevalence of SBS symptoms in building environments. Its findings can contribute to creating healthier and more productive living conditions for students.

Background: Sick Building Syndrome (SBS) is a syndrome caused by the work environment. SBS is stated as a health problem in the work environment which is related to poor indoor air quality. The Central Java Provincial Health Office building is in the city center so it is an environment prone to air pollution. The purpose of this study was to determine the factors that influence SBS symptoms in Central Java Provincial Health Office employees. Methods: This study uses an analytic study type with a cross-sectional approach. The sample in this study were 73 respondents. The sampling technique used purposive sampling technique. The instruments used were questionnaires and measurements. The data analysis used the chi square statistical test. Results: The results of this study showed that among the 73 respondents there was a relationship between age and SBS symptoms (p=0.020), there was a relationship between gender and SBS symptoms (p=0.010), there was a relationship between years of service and SBS symptoms (p=0.020 ), there was a relationship between room temperature and SBS symptoms (p=0.007), there was a relationship between the number of bacteria and SBS symptoms (p=0.004), there was no relationship between room air humidity and dust levels and SBS symptoms. Conclusion: Age, gender, length of service, and number of bacteria are factors associated with SBS symptoms. In an effort to reduce the risk of SBS symptoms, workers need to relax body muscles, optimize the use of AC, increase AC maintenance, turn off the AC for a moment and open windows periodically.

Sick building syndrome in air-conditioned museum

ABSTRACT Exposure to indoor contaminants in air-conditioned buildings can cause serious health effects to their occupants. The failure to control indoor air contaminants is one of the factors that contribute to poor indoor air quality (IAQ) and is a major contributor to sick building syndrome (SBS) symptoms. This study aims to investigate the relationship between the maintenance of mechanical ventilation and air conditioning (MVAC) that is installed in museums towards IAQ and SBS. Data were collected through site visits and observations with a combination of field measurements and a questionnaire survey. The field measurements results show that several locations in the museums were in a state of heat discomfort. The recorded measurement of air velocity was very low and the average level of HCHO concentrations are above the permissible level. The correlation test between the satisfaction level of MVAC maintenance on IAQ and SBS also shows significant relationships, indicating that MVAC maintenance in the museum affects the comfort and health of the occupants.

Effects of indoor temperature on office workers’ performance: an experimental study based on subjective assessments, neurobehavioral tests, and physiological measurements

Indoor temperature has a critical impact on the performance of office workers. This study aimed to evaluate the effect of indoor temperature on work performance through subjective assessments, neurobehavioral tests, and physiological measurements. The experiment was conducted in a controlled office environment. Under each temperature condition, participants voted on their perception of thermal sensation, thermal satisfaction, and sick building syndrome (SBS) symptoms. Participants were given neurobehavioral tests based on a ten-item task, and their body temperature, blood pressure, heart rate, and blood oxygen saturation were measured before and after the tests. The study showed that the effect of indoor temperature on the test tasks varied greatly and depended on the task type. The indoor temperature, thermal sensation votes, and body temperature for optimum work performance were 17 °C, −0.57, and 36.4 °C, respectively. Work performance was positively correlated with thermal satisfaction votes and negatively correlated with sleepiness intensity. Practitioner summary: Work performance is closely related to indoor temperature. This study evaluated the effect of indoor temperature on work performance through subjective assessments, neurobehavioral tests, and physiological measurements. The relationships between work performance and indoor temperature, perceived votes, and physiological parameters were established, respectively.
