Effects of indoor air quality on the pulmonary function of schoolchildren in Harbin

  Objective  To explore the indoor air quality of Harbin and its suburbs, and analyze the influence of indoor air quality on the pulmonary function indexes of schoolchildren, and to provide a reference for preventing the related respiratory diseases.  Methods  The concentration of CO₂, formaldehyde, benzene, PM₁₀ and total bacterial count in indoor of 80 residents in Harbin and its suburb were monitored. The IAAH model was used to evaluate the indoor air quality, and the correlation between the indoor air quality and the pulmonary function indexes of schoolchildren was analyzed.  Results  The levels of indoor air pollutant in suburb was higher than that in the urban of Harbin, and the concentration of CO₂, PM₁₀ and total bacteria count in the suburb of Harbin increase significantly during the heating season(t=5.86, 4.92, 21.16, P < 0.05). Among the 40 households monitored by IAAH model in suburb during heating season, 37.5% had moderate air pollution, and 20.0% had severe air pollution. The IAAH was correlated with FVC, FEF75% and FEF25% after excluding the confounding factors by multiple linear regression(β=-0.17, -0.34, -0.43, P < 0.05).  Conclusion  Indoor air pollution is very serious in the suburb of Harbin during heating season, which should be paid attention to by parents to prevent related respiratory diseases of schoolchildren.
