唐山市不同大气污染区小学生因病缺课情况分析

Prevalence of Pupils' Illness-induced Absence in Air Pollution Area in Tangshan

目的了解唐山市不同大气污染区小学生因病缺课情况,探讨小学生因病缺课率作为反映大气污染影响人群健康的监测指标的可行性。方法在唐山市工业区、清洁区、商业区、交通区共选取1 332名小学生为研究对象,进行因病缺课率调查。结果在均衡了4区小学生的个人生理因素、家庭因素和室内空气污染因素后,工业区、商业区、交通区、清洁区因病缺课率分别为32.6%,30.2%,40.1%,24.8%(P<0.01)。结论大气污染可导致小学生因病缺课率增高。小学生因病缺课率可以作为反映大气污染影响人群健康的监测指标。

Objective To study the prevalence of pupils＇ illness-induced absence in air pollution area in Tangshan,and to explore the feasibility of taking pupils＇ illness-induced absence as a sensing index to public health of air pollution.Methods Totally 1 332 pupils,who reside in industrial area,clean area,sowntown and near traffic center respectively were chosen.The prevalence rate of pupils＇ illness-induced absence was investigated.Results After individual physiology factors and indoor air pollution being balanced,the illness-induced absence rates were 32.6%,30.2%,40.1% and 24.8%,respectively（P〈0.01）.Conclusion Air pollution can lead to the increasing of illness-induced absence.Pupils＇ illness-induced absence can be used as a sensing index to public healthy of air pollution.
