背景：每年，急性细支气管炎（AB）的发病高峰在冬季，可能与空气污染有关。目的：将AB的门诊、急诊和住院次数与气候因素和空气污染相关联。患者和方法：入组了在门诊、急诊室就诊或在天主教大学医院儿科病房就诊的1岁以下AB患者。有关呼吸道合胞病毒（RSV）的信息来自天主教大学医学调查中心。空气污染指数，如小于10微米/立方米（PM 10），小于2.5微米/立方米（PM 2.5），CO，SO 3和O 3的颗粒物从大都会环境服务。温度、湿度和降水量来自智利气象局。结果：收集了99例门诊和442例急诊（55%为男性，平均年龄4.8个月）。152例（34.4%）住院。在急诊室咨询的儿童中，30%小于3个月，其中43%住院。在307例患者中进行了RSV研究，52%为阳性。RSV阳性患者的住院率高于RSV阴性患者（分别为52.5%和22%，p<0.001）。没有观察到环境变量或空气污染与咨询次数之间的关联。年龄小和家中吸烟是急性毛细支气管炎住院的主要危险因素。结论：环境变量并不影响急性毛细支气管炎的病例数。年轻和接触烟草烟雾是入院的风险因素（Rev Med Chile 2003; 131：1117-22）。(Key关键词：空气污染物，环境;细支气管炎;烟草烟雾污染）
Background: Annually, acute bronchiolitis (AB) occurrence peaks during winter and is probably associated with air pollution. Aim: To relate the number of ambulatory consultations, emergency and hospital admission due to AB with climatic factors and air pollution. Patients and methods: Patients of less than 1 year old with AB that consulted to outpatient clinics, the emergency room or were admitted to the Pediatrics ward of the Catholic University Hospital, were enrolled. Information about respiratory syncytial virus (RSV) was obtained from the Catholic University Medical Investigation Center. Indices of air pollution such as particulate matters of less than 10 microns/m 3 (PM 10), of less than 2.5 microns/m3 (PM 2.5), CO, SO 3 and O 3 were obtained from the Metropolitan Environmental Service. Temperature, humidity and precipitations were obtained from the Chilean Meteorological Service. Results: Ninety nine consultations in out patient clinics and 442 in emergency rooms were collected (55% male, mean age 4.8 months). One hundred fifty two were admitted (34.4%). Thirty percent of children consulting in emergency rooms were younger than 3 months and 43% of them were hospitalized. The RSV study was made in 307 patients and 52% were positive. There was a higher rate of hospital admissions among RSV positive than RSV negative patients (52.5 and 22% respectively, p<0.001). No association between environmental variables or air pollution and the number of consultations was observed. Young age and smoking inside the household were the main risk factors for hospital admission due to acute bronchiolitis. Conclusions: Environmental variables did not influence the number of cases of acute brochiolitis. Young age and exposure to tobacco smoke were risk factors for hospital admission (Rev Med Chile 2003; 131: 1117-22). (Key Words: Air pollutants, environmental; Bronchiolitis; Tobacco smoke pollution)
