To explore the health effect of traffic exhausts on children’s behavioral problems by using the Achenbach’s Child Behavior Checklist.
Three primary schools were chosen based on the counts of automobiles that passed by and the monitoring data of ambient air pollutants. All students from Grade 2 to Grade 5 were chosen as the target population and were investigated with a self-completion questionnaire as well as the Achenbach’s Child List. Finally, 1363 cases were analyzed, of whom have been local resident for more than 2 years and were in condition during investigation.
A total of 141 children, with the rate of 10.34%, were reported to have behavioral problems. The reported rates of behavioral problems are 9.04% in School A1, 9.77% in School A2, and 11.99% in School A3, respectively. However, there was no significant difference χ2 = 2.556, P = 0.279. The reported rate of behavioral problems in boys’ is higher than that of girls’ in all schools. Analysis of 11 behavioral problem factors showed that, the highest rates of Depression, Social withdrawal, Hyperactivity, Sexual problem, Cruelty, and Forcing were found in School A3. Single-factor analysis showed that fever experience, eye sight condition, drinking experience of children, experience of being beaten and scolded, second hand smoke exposure, drinking habit of father, occupation of parents, education level of parents, born at full-term, medical history in neonatal period, history of unhealthy pregnancy of mother, history of touching adverse factors and drinking experience of mother during pregnancy had a significant influence on the reported rate of behavioral problems.
Traditional factors are still the main influencing factors of children's behavioral problems. Moreover, long term-low level exposure to traffic exhausts may be related to the increase in reported behavioral problems.
