背景。胆结石和肥胖被认为是胆道癌的危险因素。由于这两个因素都与饮食有关，我们在一项基于人群的病例对照研究中研究了饮食摄入与目标癌症之间的关系。研究人群包括111名患者和480名对照组。通过半定量食物频率问卷来评估食物摄入量。从病例和对照者本人（直接答复者）或亲属（间接答复者）获得食物和微量营养素摄入量的估计数。参与者被分为不同的摄入量。风险比采用logistic回归分析估计。主要发现与蔬菜消费相关的风险单调降低（or值1.0,0.7,0.4；P值趋势）
Background. Gallstones and obesity have been suggested as risk factors for cancer of the biliary tract. Since both factors are related to diet, we studied the relationship between dietary intake and the cancer of interest in a population-based case-control study.Methods. The study population comprised 111 patients and 480 controls. Food intake was assessed by means of a semiquantitative food frequency questionnaire. Estimates of the intake of foods and micronutrients were obtained from cases and controls themselves (direct respondents) or from relatives (indirect respondents). Participants were categorized into tertiles of intake. Risk ratios were estimated by logistic regression analysis.Results. The major findings are a monotonic decrease in risk associated with the consumption of vegetables (ORs 1.0, 0.7, 0.4; P value trend
