【摘要】 目的明确短期空气污染与儿童青少年血压的关系,为采取健康干预措施和加强学校卫生管理工作提供科学依据。方法采用整群抽样的方法,在苏州城区、郊县共监测12所中小学校2 925名儿童青少年。采用《学生健康状况及影响因素调查表》进行问卷调查及体格检查,同时收集同时期大气污染物日监测资料。结果调整相关危险因素后,空气污染与儿童青少年血压升高存在正相关,PM10,PM2.5,SO₂,NO₂每增加10μg/m³,OR值（95%CI）分别为1.09（1.02～1.16）、1.12（1.03～1.22）、1.59（1.22～2.07）和1.09（1.02～1.16）; CO每增加0.1 mg/m³,OR值（95%CI）=1.11（1.02～1.19）;AQI每增加10个单位,OR值（95%CI）=1.09（1.02～1.17）。结论空气污染是儿童青少年血压升高的危险因素,PM10,PM2.5,SO₂,CO,NO₂及AQI指数与动脉血压的升高有不同程度的正相关。更多还原

【Abstract】 Objective This study aims to study the relationship between short-term exposure of air pollution and blood pressure of children and adolescents,and to provide scientific basis for further health intervention measures and strengthening school health work management. Methods Totally 2 925 children and adolescents from 12 schools（ including primary schools and high schools） in rural and urban area of Suzhou were monitored by means of cluster sampling. The survey was conducted by using the questionnaire on the health status and influencing factors of students. Physical examination was also carried out. Daily concentrations of air pollutants were collected during study period. Results There was a positive association between air pollution and blood pressure. After adjusting relevant risk factors,with PM2.5,PM10,SO₂,NO₂ increasing by 10 μg/m³,OR were 1.09（ 95%CI= 1.02-1.16）,1.12（ 95%CI = 1.03-1.22）,1.59（ 95%CI = 1.22-2.07）,and 1.09（ 95%CI = 1.02-1.16）,respectively. The OR（ 95%CI）of high blood pressure in children and adolescents was 1.11（ 95%CI = 1.02-1.19） for an increase of 0.1 mg/m³ in CO,and 1.09（ 95%CI= 1.02-1.17） for every 10 units of AQI. Conclusion Air pollution is a risk factor for the increase of blood pressure in children and adolescents. PM10,PM2.5,SO₂,CO,NO₂ and AQI are positively correlated with arterial blood pressure.更多还原
