Eur J Nutr:血清甜菜碱与乳腺癌风险负相关

2016-02-22 MedSci MedSci原创

血清甜菜碱与乳腺癌风险呈负相关。

目的

胆碱和甜菜碱是重要的DNA甲基化和合成底物,可能影响肿瘤致癌基因的作用。据我们所知,目前尚没有流行病学研究报告血清胆碱和甜菜碱与乳腺癌风险之间的关系。本研究旨在检验血清胆碱和甜菜碱是否与中国女性罹患乳腺癌的风险呈负相关。

方法

医院病例对照研究招募了510名乳腺癌病例和518例相匹配(年龄和居住地)控制患者,采集500例病例和500例对照组的血液样本。使用高效液相层析化验质谱分析血清胆碱和甜菜碱浓度。使用多元无条件logistic回归估计优势比(ORs)和95%置信区间(CIs)。

结果

乳腺癌风险与血清甜菜碱浓度呈负相关(OR 0.68, 95%CI 0.47–0.97) ,与血清甜菜碱/胆碱比值负相关(OR 0.70,95%CI 0.48-1.00),但与血清胆碱浓度无关联(OR 0.80, 95%CI 0.56–1.15)低叶酸饮食参与者中,血清甜菜碱与乳腺癌风险呈强烈负相关(OR 0.48, 95%CI 0.30–0.77)。

结论

血清甜菜碱与乳腺癌风险呈负相关。这个结果需要进一步的前瞻性研究加以证实。
