摘  要:目的探讨青岛地区膳食因素与乳腺癌患病风险的关系,为乳腺癌的病因研究及一级预防提供科学的理论依据。方法采用病例对照研究设计,通过半定量食物频率表法,对200例乳腺癌患者和200例对照进行问卷调查,调查内容包括基本情况和膳食情况两大部分。结果经单因素和多因素非条件logistic回归分析,结果显示,食物种类中,与低水平蔬菜摄入量相比,较高水平的蔬菜摄入量可能降低乳腺癌的患病风险(OR=0.429,95%CI:0.223~0.827,P=0.012);与低水平红肉摄入量相比,较高水平的红肉摄入量可能增加乳腺癌的患病风险(OR=2.185,95%CI:1.077~4.431,P=0.030)。膳食营养素中,与低水平脂肪摄入量相比,中、高及较高水平的脂肪摄入量均可能增加乳腺癌的患病风险,且随着脂肪摄入量增多,其OR值也递增,且差异均有统计学意义(OR值分别为2.478、2.533、2.799,95%CI分别为1.245~4.933、1.130~5.675、1.449~5.470,P〈0.05,P〈0.01);与低水平蛋白质摄入量相比,中、高及较高水平的蛋白质摄入量均可能增加乳腺癌的患病风险(OR值分别为3.484、3.860、3.467,95%CI分别为1.872~6.848、1.972~7.554、1.778~6.762,P〈0.01);而与低水平铁摄入量相比,中、高及较高水平的铁则可能降低乳腺癌的患病风险(OR值分别为0.528、0.479、0.340,95%CI分别为0.297~0.939、0.241~0.953、0.153~0.758,P〈0.05,P〈0.01);与低水平视黄醇当量相比,中、高及较高水平视黄醇当量则可能降低乳腺癌的患病风险(OR值分别为0.428、0.409、0.175,95%CI分别为0.227~0.806、0.217~0.769、0.080。0.385,P〈0.01)。结论建议调整饮食结构,增加蔬菜类摄入量,减少肉类摄入量。Objective To investigate the relationship between diet nutrition and breast cancer risk in Qingdao area. Methods A case-control study was performed among 200 patients diagnosed with breast cancer and 200 disease-free controls, the information on dietary intake and anthropological was collected with the semi-quantitative food frequency questionnaire. Results In food items, higher vegetable intake may cause decreasing of breast cancer risk (OR=0.429, 95%CI: 0.223-0.827, P=0.012), higher red meats intake may cause increasing of breast cancer risk (OR=2.185,95%CI:1.077-4.431,P=0.030). For the intakes of dietary nutrients, compared with a lower fat intake, low fat intake, high fat intake and higher fat intake all may cause increasing of breast cancer risk (OR=2.478, 95%CI: 1.245-4.933, P=0.010; OR=2.533, 95%CI: 1.130-5.675, P=0.024; OR=2.799, 95%CI: 1.449- 5.470, P=0.002). And so do the protein (0R=3.484,95%CI: 1.872-6.848,P=0.001; OR=3.860, 95%CI: 1.972-7.554, P=0.001; OR=3.467, 95%CI: 1.778-6.762,P=0.001 ). But compared with a lower iron intake, low iron intake, high iron intake and higher iron intake all may cause decreasing of breast cancer risk (OR=0.528, 95%CI: 0.297-0.939, P=0.030; 0R=0.479,95%CI:0.241 - 0.953 ,P=0.036; 0R=0.340,95%CI: 0.153-0.758, P=0.008).So do the retinol (OR=0.428, 95%CI: 0.227-0.806, P=0.009; OR= 0.409, 95%CI: 0.217-0.769, P=0.006; OR=0.175, 95%CI: 0.080-0.385, P=0.001 ). Conclusion It is necessary to adjust the food structure, decrease the intake of red meat, increase the intake of vegetables, and diversify the food items.
