Reports of seasonal variation of the incidence of pulmonary embolism and deep venous thrombosis are inconsistent as to when or if it occurs. We used data from the National Hospital Discharge Survey and the United States (US) Bureau of the Census to test for circannual variation throughout the entire US and in regions of the US over a period of 21 years. Pulmonary embolism, deep venous thrombosis, or the combination did not show seasonal variation in the US or in any region of the US, including the Southern region, where winters are mild, and the northeastern and midwestern regions, where seasons are sharply defined.
关于肺栓塞和深静脉血栓形成发病率的季节性变化报告，在其发生时间或是否存在季节性变化方面并不一致。我们使用了来自美国国家医院出院调查和美国人口普查局的数据，对整个美国以及美国各地区在21年期间的年周期变化进行了测试。在美国或美国的任何地区，包括冬季温和的南部地区以及季节分明的东北部和中西部地区，肺栓塞、深静脉血栓形成或两者合并均未显示出季节性变化。
