背景 有关幼年期初动吸烟与肺癌危险性的关系很少有研究报道。本研究旨在评价女性被动吸烟特别是青少年期被动吸烟患肺癌的危险性。 方法 以暴露于家庭成员的吸烟环境作为被动吸烟,在中国哈尔滨进行1:1病例——对照配对研究。我们询问了114例年龄在30～69岁的女性原发性肺癌患者及同一医院的对照。对照为非癌患者,来自病例同一医院,年龄±5岁,具有相同的居住环境及吸烟状况。其中59对病例一对照有吸烟史,55对无吸烟史。被动吸烟的数据资料按下列年龄组的家庭收集:0～6,7～14,15～22,23～30,31～69岁。
Background Little research has been reported on the relationship between early childhood smoking and lung cancer risk. The purpose of this study was to evaluate the risk of lung cancer in passive smoking, especially in adolescents. Methods 1:1 case-control paired studies were conducted in Harbin, China, as a passive smoking smoking environment exposed to family members. We asked 114 women with primary lung cancer aged 30-69 years and controls from the same hospital. The controls were non-cancer patients from the same hospital, age ± 5 years old, with the same living environment and smoking status. Among them, 59 cases had a smoking history and 55 had no smoking history. Data on passive smoking are collected by families in the following age groups: 0-6, 7-14, 15-22, 23-30, 31-69 years old.
