概括
这项研究发现,较高的血液铁含量与较低的肺癌风险有关,特别是肺腺癌. 门德尔的随机化分析支持铁.
科学领域:
- 环境健康 环境健康
- 在瘤学瘤学.
- 遗传流行病学遗传流行病学
背景情况:
- 证实了重金属暴露与肺癌风险之间的关联.
- 关于血液金属元素与肺癌之间的确切关系仍然存在不确定性.
- 这项研究调查了血液金属与肺癌之间的关联和因果关系.
研究的目的:
- 为了探索血液金属元素与肺癌之间的联系.
- 使用孟德尔随机化 (MR) 检查血液金属元素和肺癌之间的因果关系.
主要方法:
- 从国家健康和营养检查调查 (NHANES) (1999-2018) 中对48,132名参与者的回顾性分析.
- 权重后勤回归用于评估血液金属 (,,,,,,,铜,铁,) 和肺癌之间的关系.
- 门德尔随机化 (MR) 分析,以调查潜在的因果关系.
主要成果:
- 在和肺癌之间观察到积极的关联.
- 在考虑混因素后,在铁和肺癌之间发现了负相关性.
- 在欧洲人中,MR分析表明铁和肺腺癌 (LUAD) 之间存在负因果关系 (ORivw =0.77,95%CI:0.65-0.92;OR加权中位数 =0.75,95%CI:0.61-0.92).
结论:
- 铁与肺癌发生率相反,这表明它在肺腺癌 (LUAD) 中起着保护作用.
- 门德尔随机化分析支持LUAD中铁的保护作用.
- 需要在大规模前性队列研究中进一步验证.

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
