The aim of this study was to evaluate the effects of air pollutants and their lag structures in relation to respiratory morbidity among children and adolescents in the city of Cubatão, São Paulo State, Brazil, from 1997 to 2004. An ecological time-series study was performed, analyzing respiratory hospital admissions of children and adolescents in National Health System hospitals in Cubatão. Generalized linear Poisson regression models were used to control for seasonality, temperature, humidity, and short-term trends. PM10 and ozone were significantly associated with respiratory hospital admissions. Among children, inter-quartile range increases in the PM10 7-day moving average (56.5µg/m³) and in the ozone 5-day moving average (46.7µg/m³) led to increases of 9.6% (95%CI: 3.0%-16.1%) and 2.4% (95%CI: 0.1%-4.7%) in respiratory hospital admissions, respectively. Efforts to reduce air pollutants need to be adopted to minimize the adverse effects on children and adolescents in Cubatão.
本研究旨在评估1997年至2004年期间，巴西圣保罗州库巴唐市儿童和青少年中，空气污染物及其滞后结构与呼吸道疾病发病率之间的关系。开展了一项生态时间序列研究，分析了库巴唐市国家卫生系统医院中儿童和青少年的呼吸道疾病住院情况。采用广义线性泊松回归模型来控制季节性、温度、湿度和短期趋势。PM10和臭氧与呼吸道疾病住院情况显著相关。在儿童中，PM10 7天移动平均值（56.5µg/m³）和臭氧5天移动平均值（46.7µg/m³）的四分位间距增加，分别导致呼吸道疾病住院率增加9.6%（95%置信区间：3.0%-16.1%）和2.4%（95%置信区间：0.1%-4.7%）。需要采取措施减少空气污染物，以尽量减少对库巴唐市儿童和青少年的不利影响。
