概括
较高的终身视网醇水平可能会降低关节骨关节炎的风险. 贝塔胡卜素显示,与增加类风湿性关节炎风险有明显的联系. 需要进一步的研究来证实这些抗氧化剂与关节炎的关联.
科学领域:
- 营养流行病学 营养流行病学
- 遗传流行病学遗传流行病学

背景情况:
- 骨关节炎 (OA) 和类风湿性关节炎 (RA) 是普遍存在的肌肉骨疾病.
- 饮食中的抗氧化剂被假设在炎症和退行性关节疾病中起作用.
- 门德尔随机化 (MR) 提供了一种方法来研究使用遗传变异的暴露和疾病之间的因果关系.
研究的目的:
- 调查饮食衍生抗氧化剂的循环水平与膝关节OA,部OA和RA风险之间的因果关系.
- 使用两个样本的MR框架来评估这些关系.
主要方法:
- 使用全基因组关联研究 (GWAS) 总结统计数据采用两样 MR 设计.
- 确定了与循环中的视网醇,β-胡卜素,柳科,维生素C和维生素E水平相关的单核酸多态 (SNPs).
- 使用反变量加权 (IVW) 作为主要分析,并补充了灵敏度分析以确保结果的稳定性.
主要成果:
- 基因预测较高的循环视网醇水平与关节骨质炎风险降低显著相关 (OR = 0.45).
- 基因预测的更高的循环β-胡卜素水平显示出与RA风险增加的暗示性关联 (OR = 1.32).

Genome-wide Association Studies-GWAS
13.6K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Cancer Prevention
6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
