ABSTRACT
OBJECTIVES: This study was conducted to investigate the effects of aircraft noise exposure on children's mental health problems such as depression and personality. METHODS: We obtained data from the health examinations of school children in the vicinity of Gunsan airport. This survey was conducted in the rural area, Gunsan during 2009. The study population included 195 children attending 4th to 6th grade from 6 elementary schools near the airport. Based on 60 Weighted Equivalent Continuous Perceived Noise Level (WECPNL) measures of aircraft noise, participants were divided into 2 groups; the exposure group consisted of 106 children from 4 schools, and the reference group included 89 children from the 2 schools in Gunsan. All children completed questions on general characteristics, the Korean Children's Depression Inventory (KCDI) for depression, and the Korea Human Nature Inspection (KHNI) for personality. RESULTS: Children in the exposure group were at higher risk of depression (5.62, 95% CI 1.12~28.25), and personality changes (2.08, 95% CI 1.07~4.05) than those of the reference group. In particular, children's diligence, cooperation, and concentration, subgroups of personality measure, were affected significantly and negatively, by aircraft noise level. CONCLUSIONS: Our results suggest that exposure to aircraft noise at school is associated with mental health problems in children. Requirements should be implemented to manage aircraft noise of its affect on children's health.
