“…For example, one report has suggested that the estimated prevalence of "MCS" is higher in patients with allergic diseases than in patients who did not have allergic diseases [37]. There is another report that indicated similar results on the association between psychological factors and "SBS" and "MCS" [16] which were observed in the pre-SBS group in this study. Regarding the personal environment, including the residential environment, showed an association with pre-SBS; a significant relationship was seen between the answer of "always" to questions relating to "condensation" status in the house, "moisture and musty odors," frequency of "use of deodorant and fragrance," and insulation efficiency of the house.…”

“…In 2017, the "Manual for Consultation and Countermeasures on Sick House Syndrome Based on Scientific Evidence (revised new edition)" was created by the Ministry of Health, Labour and Welfare Research Group [14], and in 2019, the Ministry of Health, Labour and Welfare further revised the values for xylene, di-n-butyl phthalate, and di(2ethylhexyl)phthalate concentrations in the guidelines [15]. Various indoor factors cause physical ailments, including chemical factors, such as exposure to chemical substances volatilizing from building materials, furniture, and household goods; biological factors, such as mold, ticks, and bacteria; physical factors, such as heat, light, noise, and radiation; and social and psychological factors of residents [16][17][18]. "SBS" is associated with the awareness of residents to improve their indoor air quality by opening windows for "ventilation," cleaning, and lifestyle and with the air environment such as indoor chemical substance concentrations, temperature, humidity, and odor [19,20].…”

Background: With the aim to prevent sick building syndrome and worsening of allergic symptoms, primarily resulting from the indoor environment, the relationships among people's residential environment in recent years, their lifestyle habits, their awareness, and their symptoms were investigated using an online survey. Methods: In the survey, respondents experiencing symptoms specific to sick building syndrome, although they were not diagnosed with sick building syndrome, were categorized in the pre-sick building syndrome group. The relationships among individual characteristics, residential environment, and individual awareness were analyzed. Results: Results showed that the prevalence of pre-sick building syndrome was high among young (aged 20-29 years) population of both sexes. In addition, "condensation," "moisture," "musty odors" in the house, and the "use of deodorant and fragrance" were all significantly associated with pre-sick building syndrome. Conversely, there was no significant association with recently built "wooden" houses that are highly airtight and have thermal insulation. Conclusions: Efficient "ventilation" plans and "ventilation" improvement and air conditioning systems to prevent mold and condensation in rooms are necessary to maintain a good, indoor environment that is beneficial for health. Efforts should also be made to encourage individuals to regularly clean and effectively ventilate their homes.

“…As such, the Robert Koch-Institut [66] in an extensive study has not found any correlations between reported or attested MCS and environmental influences, but found a causal connection to psychosomatic problems. Other studies carried out for workers' link MCS, SBS, or SHS with mental health, too [67][68][69]. As the causes for stress are also partly related to the home environment, it can be argued that this home-related stress (noise, loneliness, apartment too small) has a negative impact such as it has been stated for asthma in children [70].…”

Indoor Air Quality and Health in Newly Constructed Apartments in Developing Countries: A Case Study of Surabaya, Indonesia

et al. 2019

In times of rapid urbanization, increasing usage of chemicals in buildings, and energy saving measures, the topic of indoor air quality (IAQ) demands reinforced attention. Nevertheless, especially in developing countries with urgent building construction needs, IAQ has hardly been examined. This study investigates the condition of IAQ and health of occupants in newly constructed high-rise apartments in contrast to traditional detached houses (Kampongs) in Surabaya, Indonesia. Information on building attributes, cleaning and ventilation behavior, interior sources, personal characteristics and health, especially multiple chemical sensitivity (MCS), was collected through 471 questionnaires. In addition, 76 measurements of TVOCs, formaldehyde and 30 measurements of mold risk were carried out. The results showed that the share of people in apartments with a very suggestive risk of MCS was twice as high as that in Kampongs (17.6% vs. 6.7%). Correlation analysis suggested that for both residential types, health problems, negative smell or perception of IAQ, and higher levels of stress determined higher degrees of MCS. For IAQ, high concentrations of formaldehyde and TVOCs were measured in apartments and corresponded to higher MCS risk, whereas severe mold issues were predicted in Kampongs. This study suggests major shortcomings in the indoor environment in newly constructed apartments for the physical and the mental health of occupants.

“…Workers Fatigue Accumulated Degree by Self-Diagnostic Questionnaire (WFAD-SQ), the self-test diagnostic scale of fatigue accumulation was developed by the Ministry of Health, Labour, and Welfare of Japan (2003) [37] and has been validated in a range of healthcare settings in Japan, China, and some other countries [41][42][43]. The degree of overwork was measured by this scale, which is a kind of simple self-test questionnaire, mainly based on the developed medical research achievements.…”

Background Overwork has become the common for some employees in China. The ‘Healthy China 2030’ plan mandates prevention of excessive overtime, making serious overwork was not advocated. Meeting new regulations requires clarification of the factors influencing overwork; however, Chinese researchers have not thoroughly examined ‘overwork’ and few proven models are available for addressing its relationship to job demands, job resources, and workaholism. Methods This study analysed these factors and overwork among employees in Chinese companies. A total of 1047 employees completed the Workers Fatigue Accumulated Degree by Self-Diagnostic Questionnaire (WFAD-SQ) for Assessment of Workers' Accumulated Fatigue to measure the degree of overwork; Workaholism Battery (WorkBAT) was applied to evaluate workaholism; the Job content qualifications (JCQ) were adopted to survey job demands–resources. Results Structural equation modelling (SEM) verified the effects shown, indicating job resources significantly negatively affect and job demands positively affect overwork. Workaholism demonstrated a significant intermediary role between job demands-resources and overwork. The SEM results indicate job demands-resources have both direct and indirect effects on overwork, and task demands, psychological requirements, and colleague support are the primary positive protective predictors for overwork. Conclusions The findings indicate the importance of employers strictly enforcing overtime rules, ensuring staffs’ rights for rest, and establishing harmonious working relationships between employees.
