北京市空气污染物对过敏性鼻炎的影响研究

 以2009年3月19日至2010年3月18日间北京医院耳鼻喉—头颈外科的过敏性鼻炎（AR）门诊就诊病人观测为基础，结合北京市空气质量，探讨空气质量与AR的关系。结果表明， AR患者的人数均随年龄的增长呈现先增加后减少的趋势，以中青年龄段（21～50岁）人数最多。春、秋季是过敏性鼻炎的易发时期，夏、冬季发病率相对较低。AR日就诊人数的时间变化趋势与空气中PM10，SO2，NO2的浓度变化具有一定的时间对应性，在观测的上半期内尤为明显，表明在短期内空气中PM10，SO2，NO2浓度的增加会直接影响AR的发生与症状加重，并导致就诊人数增加

Effect of Air Pollutants on Allergic Rhinitis in Beijing

To investigate the effect of the global environment change on urbanization and health, daily numbers of persons consulting general practitioners for allergic rhinitis（AR） between March 19 th2009 and March 18th 2010 were obtained from Department of Otolaryngology Head and Neck Surgery, Beijing Hospital, Ministry of Public Health. Data of atmospheric concentrations of PM10, NO2 and sulfur dioxide SO2 were collected. The relationship between concentration of air pollutants and the number of outpatients and emergency for allergic rhinitis in Beijing was studied. The results showed that the number of both male patients and female patient has the same increasing trends with the age. About 74.34% of the patients were 21 to 50 years. Spring and autumn had a higher morbidity of AR than summer and winter. The number of medical consultations for allergic rhinitis was correlated with the three air pollutants during March 19th2009 to September 18th2009, showed that the air pollutants had short term effects on allergic rhinitis, exacerbating symptoms and increasing hospital admissions.
