Effects of Indoor Environmental Factors on Respiratory Health of Children in a Subtropical Climate

This study was conducted to determine whether indoor environmental factors affected respiratory symptoms in 4164 primary school children in Kaohsiung rural areas of Taiwan. Information on respiratory health symptoms and characteristics of the housing was obtained using a written questionnaire, completed by the parents of children. Multiple logistic regression analysis examined the relationship between respiratory health symptoms (cough, wheezing, bronchitis, asthma, and allergic rhinitis) and housing factors. Home dampness was significantly associated with all respiratory health symptoms. Incense burning and mosquito repellant burning showed effects on the reporting of coughing symptoms. No apparent associations were found with the other indoor factors included in this study or respiratory health symptoms. We conclude that dampness in the home has a pronounced effects on respiratory health symptoms and is a new public health issue in subtropical areas.
