N2 - The indoor air quality in children's home is closely associated with respiratory allergy symptoms. We analyzed the relationship between respiratory allergy symptoms and living environment for school-age children around 10 years old in Harbin China by cross-sectional study, and selected 10 residences (6 case group and 4 control group) to monitor temperature and humidity, carbon dioxide (CO2), particulate matter, total volatile organic compounds (TVOCs) and semi-volatile organic compounds (SVOCs). The preliminary questionnaire survey showed that the indoor humidity (P=0.013, OR=0.193) and drying clothes (P=0.045, OR=0.387) in children's bedroom were protective factors for respiratory allergy symptoms, while decoration (P=0.001, OR=3.534) and pet keeping (P=0.003, OR=4.421) were risk factors. The high temperature and dryness environment may lead childhood asthma and respiratory illness; the distribution of CO2 was largely explained by active avoidance behavior. The average mass concentration of particulate matter in case group was higher than that in control group, and both were higher than outdoor concentration. TVOCs were lower than the national standard of 600 mg/m3 in all measured residences; the respiratory allergic symptoms in childhood may be associated with the high detection frequencies of di(2-ethylexyl) phthalate (DEHP) and dibutyl phthalate (DBP) in house dust.
