摘要
目的了解2013—2017年天津市儿童室内空气污染危险因素的分布情况,探讨其年度变化趋势。方法2013—2017年在天津市共调查4515名儿童的家庭室内空气污染危险因素分布情况,统计分析天津市儿童住房情况、室内空气污染危险因素和室内空气污染保护因素的分布特征,采用Joinpoint回归和卡方趋势检验分析其变化趋势。结果2013—2017年分别调查594、670、1128、1030、1093名儿童,结果显示儿童住房周边有污染源、住房距主干线<20 m的情况呈下降趋势,年度变化百分比(APC)为-5.6%~-27%(P<0.05),燃烧煤或秸秆等固体燃料进行取暖和烹饪、使用家用化学品的APC呈下降趋势,家庭油烟机和空气净化器的使用情况呈上升趋势。儿童家庭住房面积<80 m^(2)、房屋3年内装修和饲养宠物的危险因素均呈上升趋势,APC分别为4.9%,11.9%和9.8%,差异有统计学意义(P<0.05)。结论2013—2017年天津市儿童室内空气污染危险因素的分布特征大多呈下降趋势,但仍有个别危险因素呈上升趋势。
Objectives To explore the distribution characteristics and trends about indoor air pollution risk factors of children during 2013-2017 in Tianjin.Methods A indoor air pollution risk factors survey of 4515 schoolchildren was conducted in Tianjin,and the children housing conditions,indoor air pollution risk factors,indoor air pollution protective factors were described and statistically calculated,the Joinpoint regression and chi-square trend analysis were used to explore the annual trends.Results 594,670,1128,1030,1093 schoolchildren carried out the questionnaire survey in 2013-2017.The results showed incidence rate of pollution sources around children's houses and the distance between house and main line less than 20 meters were on a downtrend,the annual percent change(APC)were between-5.6%to-27%(P<0.05).The incidence rate of use solid-fuel to warm or cook and use household chemical were decreased,and kitchen ventilator and air purifier usage were increased.But it was noteworthy that,the incidence rate of children's houses area less than 80 square meter,housing renovation in recent 3 years,keeping pets were increased,the APC were 4.9%,11.9%and 9.8%,respectively.Conclusion The distribution trends about indoor air pollution risk factors of children during 2013-2017 in Tianjin were mostly on downtrend,but still a few were on uptrend.
