Meat intake has been linked to increased risk of colorectal cancer (CRC) and mortality. However, diet composition may affect the risks. We aimed to estimate associations between red and processed meat and poultry intake and risk of CRC and all-cause mortality and if they are modified by dietary quality using Cox regression analyses. Baseline dietary data were obtained from three survey rounds of the Danish National Survey on Diet and Physical Activity. Data on CRC and all-cause mortality were extracted from national registers. The cohort was followed from date of survey interview-or for CRC, from age 50 years, whichever came last, until 31 December 2017. Meat intake was analysed categorically and continuously, and stratified by dietary quality for 15-75-year-old Danes at baseline, n 6282 for CRC and n 9848 for mortality analyses. We found no significant association between red and processed meat intake and CRC risk. For poultry, increased CRC risk for high versus low intake (HR 1.62; 95%CI 1.13-2.31) was found, but not when examining risk change per 100 g increased intake. We showed no association between meat intake and all-cause mortality. The association between meat intake and CRC or mortality risk was not modified by dietary quality.
肉类摄入与结直肠癌(CRC)和死亡率的风险增加有关。然而,饮食结构可能会影响这些风险。我们旨在使用 Cox 回归分析来估计红肉和加工肉类以及禽肉摄入量与 CRC 和全因死亡率风险之间的关联,以及它们是否受到饮食质量的影响。基线饮食数据来自丹麦国家饮食和体力活动调查的三轮调查。CRC 和全因死亡率的数据从国家登记册中提取。该队列从调查访谈之日起或从 50 岁起(以最后一个为准)开始随访,直到 2017 年 12 月 31 日。在基线时,根据饮食质量将肉类摄入量进行分类和连续分析,15-75 岁的丹麦人分析 n=6282 例 CRC 和 n=9848 例死亡率分析。我们没有发现红肉和加工肉类摄入量与 CRC 风险之间存在显著关联。对于禽肉,高摄入量与低摄入量相比,CRC 风险增加(HR 1.62;95%CI 1.13-2.31),但每增加 100 克摄入量时,风险变化没有增加。我们没有发现肉类摄入与全因死亡率之间存在关联。肉类摄入与 CRC 或死亡率风险之间的关联不受饮食质量的影响。
