通过国际饮食质量指数 (DQI-I) 衡量高质量的饮食,与乳腺癌 (BrCa) 的风险降低有关. 这表明健康的饮食模式对于伊朗人口的BrCa预防至关重要.
科学领域:
- 营养流行病学 营养流行病学
- 在瘤学瘤学.
- 公共卫生 公共卫生
背景情况:
- 饮食质量是乳腺癌 (BrCa) 发展的一个公认因素.
- 需要进一步的研究来澄清饮食与BrCa的关系,特别是在不同的人群中.
- 这项研究旨在使用国际饮食质量指数 (DQI-I) 评估伊朗妇女的饮食质量,以评估与 BrCa 风险的关系.
研究的目的:
- 调查由国际饮食质量指数 (DQI-I) 评估的饮食质量与伊朗人口乳腺癌风险之间的关联.
主要方法:
- 一项涉及134名乳腺癌患者和267名对照者的病例控制研究.
- 通过使用食物频率问卷来计算DQI-I得分来评估饮食摄入量.
- 采用多变量逻辑回归模型来分析DQI-I与乳腺癌几率之间的关联.
主要成果:
- 较高的DQI-I得分 (最后三位数) 与较低的乳腺癌几率显著相关 (OR=0.30,95%CI:0.15-0.56).
- 亚组分析显示,更年期前 (OR=0.27,95% CI:0.10-0.70) 和更年期后妇女 (OR=0.35,95% CI:0.13-0.92) 的乳腺癌几率下降.
结论:
- 根据DQI-I的指标,更高的饮食质量与患乳腺癌的可能性降低有关.
- 采用健康的饮食模式对于有效的乳腺癌预防策略至关重要.
