Abstract [en]

In order to evaluate the perceived home indoor air quality, as well as sick building syndrome (SBS) in areas with typical arid continental climate such as Urumqi, northwest of China, a cross-sectional study including 4,260 parents of children (1-8 years) was performed by a questionnaire survey in winter season in 2011. The sensation of air dryness (weekly/sometimes) in the last 3 months had the highest proportion of reports by more than half of the parents (57.4 %), followed by perceived stuffy odor (40.6 %), unpleasant odor (27.0 %), tobacco smoke odor (25.5 %), sensation of humid air (17.9 %), pungent odor (11.7 %) and moldy odor (9.5 %), respectively. The prevalence of SBS symptoms in the same time period was 40.4 % for general symptom, 47.7 % for mucosal symptom and 9.5 % for skin symptom, respectively. There were significant associations between perceived odors/sensation of air dryness and SBS symptoms (ORs range 1.39-1.42). Additionally, the OR values increased with an increase of the OH score (P < 0.05). Dampness, the presence of cockroaches and mosquitoes/flies, prenatal exposure to decoration and close to traffic were all risk factors of SBS symptoms. However, frequently putting bedding to sunshine was potentially a protective factor. In conclusion, adults' perceptions of odors and sensation of air dryness are related to SBS symptoms and home environmental factors in Urumqi, China.
