BACKGROUND Risk reduction through dietary modifications is an adjunct strategy for prevention of oesophageal cancer, a leading cause of cancer-related mortality and morbidity worldwide. We aimed to estimate the association between calcium and magnesium intakes and incident oesophageal cancer (OC). METHODS We conducted a retrospective analysis of the NIH-AARP Diet and Health Study prospective cohort. We used multivariable Cox proportional hazard modeling to estimate the association between total intakes and incident OC overall and by histology (oesophageal squamous cell carcinoma (OSCC) and adenocarcinoma (OAC)). Sensitivity and stratified analyses were performed. RESULTS Among 536,359 included respondents, 1414 incident OCs occurred over 6.5 million person-years follow-up time. Increasing dietary calcium intake was associated with an adjusted 32-41% lower risk of OSCC compared to the lowest quartile (p-trend 0.01). There was a positive association between increasing magnesium intake and OAC risk, but only among participants with low calcium:magnesium intake ratios (p-trend 0.04). There was a significant interaction with smoking status. CONCLUSIONS Based on a retrospective analysis of the NIH-AARP Diet and Health Study prospective cohort, dietary intakes of calcium and magnesium were significantly associated with risk of OSCC and, among certain participants, OAC, respectively. If validated, these findings could inform dietary modifications among at-risk individuals. Mechanistic investigations would provide additional insight.

钙和镁摄入量与食道癌风险之间的关联:NIH-AARP饮食与健康研究前瞻性队列分析。

背景技术通过饮食调节降低风险是预防食道癌的一种辅助策略,食道癌是全球范围内与癌症相关的死亡率和发病率的主要原因。我们旨在评估钙和镁的摄入量与食道癌(OC)的相关性。方法我们对NIH-AARP饮食与健康研究前瞻性队列进行了回顾性分析。我们使用了多变量Cox比例风险模型,通过组织学(食管鳞状细胞癌(OSCC)和腺癌(OAC))估算了总摄入量与总OC摄入量之间的关联。进行敏感性和分层分析。结果在536359名受访者中,有1414个事件OC发生了超过650万人年的随访时间。与最低四分位数相比,膳食钙摄入量的增加与经调整的OSCC风险降低了32-41%有关(p趋势0.01)。镁摄入量与OAC风险之间存在正相关关系,但仅在钙镁摄入量比例低的参与者中存在(p趋势0.04)。与吸烟状况存在显着的相互作用。结论基于对NIH-AARP饮食与健康研究前瞻性人群的回顾性分析,饮食中钙和镁的摄入与OSCC的风险显着相关,在某些参与者中,其与OAC的风险显着相关。如果得到证实,这些发现可为高危人群饮食调整提供依据。机械调查将提供更多的见解。镁摄入量与OAC风险之间存在正相关关系,但仅在钙镁摄入量比例低的参与者中存在(p趋势0.04)。与吸烟状况存在显着的相互作用。结论基于对NIH-AARP饮食与健康研究前瞻性人群的回顾性分析,饮食中钙和镁的摄入与OSCC的风险显着相关,在某些参与者中,其与OAC的风险显着相关。如果得到证实,这些发现可为高危人群饮食调整提供依据。机械调查将提供更多的见解。镁摄入量与OAC风险之间存在正相关关系,但仅在钙镁摄入量比例低的参与者中存在(p趋势0.04)。与吸烟状况存在显着的相互作用。结论基于对NIH-AARP饮食与健康研究前瞻性人群的回顾性分析,饮食中钙和镁的摄入与OSCC的风险显着相关,在某些参与者中,其与OAC的风险显着相关。如果得到证实,这些发现可为高危人群饮食调整提供依据。机械调查将提供更多的见解。结论基于对NIH-AARP饮食与健康研究前瞻性人群的回顾性分析,饮食中钙和镁的摄入与OSCC的风险显着相关,在某些参与者中,其与OAC的风险显着相关。如果得到证实,这些发现可为高危人群饮食调整提供依据。机械调查将提供更多的见解。结论基于对NIH-AARP饮食与健康研究前瞻性人群的回顾性分析,饮食中钙和镁的摄入与OSCC的风险显着相关,在某些参与者中,其与OAC的风险显着相关。如果得到证实,这些发现可为高危人群饮食调整提供依据。机械调查将提供更多的见解。
