本研究旨在探讨粗颗粒物（PM2.5-10）浓度与高雄市呼吸系统疾病住院率之间的相关性。研究对象为高雄市2006年至2010年期间因慢性阻塞性肺病（COPD）、气喘、肺炎等疾病而入院的病患，以及环境空气污染程度。使用病例交叉方法估计因RD住院的相对风险，控制天气变量、一周中的日期、季节性和长期时间趋势。单一污染物模型（不调整其他污染物），增加的RD入院率仅在凉爽的日子（<25 °C）与较高的粗PM水平显着相关，PM2.5-10浓度升高10 µg/m3与3%（95% CI = 1%-5%），哮喘入院增加4%（95% CI = 1%-7%），肺炎入院增加3%（95% CI = 2%-4%）。在温暖的日子里，粗颗粒水平与RD住院人数之间没有发现显着相关性。在两种污染物模型中，PM2.5-10水平仍然与较高的RD入院率显着相关，即使在凉爽的日子控制二氧化硫，二氧化氮，一氧化碳或臭氧。这项研究提供的证据表明，较高水平的PM2.5-10增加了在凉爽的日子里因RD住院的风险。
This study was undertaken to determine whether there was an association between coarse particles (PM2.5–10) levels and frequency of hospital admissions for respiratory diseases (RD) in Kaohsiung, Taiwan. Hospital admissions for RD including chronic obstructive pulmonary disease (COPD), asthma, and pneumonia, and ambient air pollution data levels for Kaohsiung were obtained for the period from 2006 to 2010. The relative risk of hospital admissions for RD was estimated using a case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. For the single pollutant model (without adjustment for other pollutants), increased rate of admissions for RD were significantly associated with higher coarse PM levels only on cool days (<25 °C), with a 10 µg/m3 elevation in PM2.5–10 concentrations associated with a 3% (95% CI = 1%–5%) rise in COPD admissions, 4% (95% CI = 1%–7%) increase in asthma admissions, and 3% (95% CI = 2%–4%) rise in pneumonia admissions. No significant associations were found between coarse particle levels and the number of hospital admissions for RD on warm days. In the two-pollutant models, PM2.5–10 levels remained significantly correlated with higher rate of RD admissions even controlling for sulfur dioxide, nitrogen dioxide, carbon monoxide, or ozone on cool days. This study provides evidence that higher levels of PM2.5–10 enhance the risk of hospital admissions for RD on cool days.
