宣威肺癌危险因素研究概述（1979～1993）

我国云南省宣威县（１９７９～１９９３）男性肺癌年龄调整死亡率是２７．７／１０５，属全国肺癌高发区之一，女性肺癌年龄调整死亡率是２５．３／１０５，居全国之首。为了研究引起肺癌高发的主要危险因素，探索暴露与疾病之间的关联强度及方向，我们以宣威县为研究基地，开展了多学科的综合性研究。其主要结论如下：（１）与工业污染未见明显联系；（２）吸烟不是宣威肺癌的主要危险因素；（３）生活燃料与宣威肺癌死亡率间存在明显联系；（４）与室内燃煤空气污染联系密切。

An overview of studies on risk factors for lung cancer in Xuanwei,China(1979～1993)

In Xuanwei county, Yunnan province. age-adjusted lung cancer mortality was 27.7/105 in males, which is among China's highest, and 25.3/105 in females, which is the China's highest.
