通过综合饮食抗氧化剂指数 (CDAI) 衡量的饮食抗氧化剂的摄入量较高,与便秘风险降低有关. 这种联系在男性中尤为强烈,这表明饮食模式在预防便秘方面发挥着作用.
科学领域:
- 营养科学 营养科学
- 胃肠病学 胃肠病学
- 公共卫生 公共卫生
背景情况:
- 氧化应激是便秘病因的一个关键因素.
- 饮食修改可以提高抗氧化剂水平并减轻氧化应激.
- 综合饮食抗氧化剂指数 (CDAI) 评估饮食抗氧化能力,但其与便秘风险的联系尚不清楚.
研究的目的:
- 调查CDAI与便秘风险之间的关联.
- 探索饮食指导在便秘管理中的潜力.
主要方法:
- 对11165名美国成年人的横截面研究 (2005-2010年NHANES数据).
- 权重后勤回归模型评估了CDAI和便秘风险.
- 限制立方线 (RCS) 和分层分析检查了非线性趋势和子组效应.
主要成果:
- 增加的CDAI与更低的便秘风险相关 (OR=0.937,p=0.012).
- 在最高CDAI四分位数中的个体,便秘风险降低了40.1% (OR=0.599,p=0.027).
- 在男性中观察到负相关性 (OR=0.871,p=0.002),最高CDAI四分位数显示59.8%的降低风险 (OR=0.402,p=0.010).
- 和维生素E摄入量在特定分析中显示出与便秘风险的独立关联.
结论:
- 在CDAI和便秘风险之间存在显著的相关性.
- CDAI显示出一种保护性关联,可以防止便秘,特别是在男性中.
- 饮食中的抗氧化剂模式,而不仅仅是单个营养素,对于理解便秘至关重要.
