title: [A matched case-control study on the relations between beta-carotene and lung cancer].
abstract: In 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 questionnaire 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 +/- 430.98 micrograms/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.
