摘要
通过１５６对１：１配比病例对照研究，分析了武汉地区肺癌患者及其一般疾病住院对照的膳食主要营养素摄入情况。结果表明，病例组膳食胡萝卜素、维生素Ｃ、纤维素摄入水平显著低于对照。作者还分析了膳食胡萝卜素摄入量与肺癌各病理类型发病危险的关系，按吸烟因素分层进行ＯＲ趋势检验，发现膳食胡萝卜素水平与肺腺癌病理类型的ＯＲ趋势无统计显著性差异，但与肺鳞癌及其它肺癌病理类型发病存在暴露剂量－反应关系。
n order to discover the
relationship between dietary nutrients intake and risk of lung cancer
1:1 matched case control study on 156 recent histologiclly diagnosed
primary lung cancer patients and 156 patients with respiratory tumour
and other related diseases as controls,was conducted in Wuhan;All
cases and controls were asked to participate in the nutritional
assessment program and a food frequency questionaire containing 64
food items was filled in. The findings showed that there was a
statistically significant difference between dietary intake of beta
carotene between the two groups(2877.13±393.43 vs. 3445±430.98μ
g/day).Having controled the confounding factor of cigarette smoking,a
significant linear trend for lower dietary carotene intake toward
higher lung cancer risk was observed.
