摘要：目的 了解老年与非老年社区获得性肺炎(CAP)的流行病学特征。方法 选取2015年1月-2017年3月于西南医科大学附属医院就诊且确诊为CAP的患者598例，根据年龄分为老年组(≥65岁)和非老年组(<65岁)，随访并记录其相关资料。结果 老年组合并慢性阻塞性肺疾病(COPD)、高血压病、冠心病、肾功能不全、脑血管疾病明显多于非老年组(P<0.05)；老年组更容易出现呼吸困难、咳脓性痰(P<0.05)，非老年组更常表现为发热、胸痛(P<0.05)；老年组D-D二聚体浓度和合并有低蛋白血症高于非老年组(P<0.05)；结论 老年与非老年CAP的流行病学特征有诸多不同，在临床工作中应区别对待，给予针对性治疗。
