目的：探讨空气污染与小学生旷课的关系。设计：对空气污染和学校缺勤数据进行时间序列分析，并控制长期趋势、季节性、星期几、假日以及气象变量。背景：1996年3月2日至1999年12月22日期间的学校缺勤数据收集自韩国首尔市一所小学的学生出勤报告。主要结果测量：通过广义加性泊松回归分析每日因病缺勤人数与每日空气污染水平的关系。在同一天计算空气污染暴露的旷工相对风险的四分位数范围（从最低值的25%到最低值的75%）。结果：暴露于空气污染物中，如空气动力学直径小于等于10的颗粒物（PM10）、二氧化硫和臭氧，与疾病相关的旷工有关。估计的相对危险度分别为：PM10每增加42.1微克/立方米1.06(95%可信区间，1.04-1.09)，二氧化硫每增加5.68亿分之一（95%可信区间，1.07-1.12），臭氧每增加15.94亿分之一（95%可信区间，1.06-1.11）。二氧化氮水平与因病缺勤之间无显著关系。结论：空气污染与小学生因病缺勤有关。
Objective: To assess the association of air pollution and school absenteeism among elementary students.Design: Time-series analysis of air pollution and school absenteeism data with controlling for long-term trends, seasonality, day of the week, and holiday as well as meteorologic variables.Setting: School absenteeism data for the period from March 2,1996, to December 22,1999, were collected from student attendance reports of one elementary school in Seoul, Korea.Main Outcome Measures: The number of daily illness-related absences was analyzed against the daily levels of air pollution by generalized additive Poisson regression. The relative risks of absenteeism for air pollution exposure of interquartile ranges (the range from the lowest 25% of the value to the lowest 75% of the value) on absenteeism were calculated on the same day.Results: Exposure to air pollutants such as particulate matter of 10 mum or less in aerodynamic diameter (PM10), sulfur dioxide, and ozone, was associated with illness-related absenteeism. The estimated relative risks were 1.06 (95% confidence interval, 1.04-1.09) per 42.1-mug/m(3) increase in PM10, 1.09 (95% confidence interval, 1.07-1.12) per 5.68-part per billion increase in sulfur dioxide, and 1.08 (95% confidence interval, 1.06-1.11) per 15.94-part per billion increase in ozone. There was no significant relationship between nitrogen dioxide level and illness-related absenteeism.Conclusion: Air pollution is associated with illness-related absences among elementary students.
