这项研究发现,不健康的低脂肪饮食增加了COPD风险. 不健康的低碳水化合物饮食与COPD患者的较高死亡率有关,而健康的低脂肪饮食与较低的死亡率有关.
科学领域:
- 营养流行病学 营养流行病学
- 肺部医学 肺部医学
- 公共卫生 公共卫生
背景情况:
- 众所周知,低碳水化合物饮食 (LCD) 和低脂肪饮食 (LFD) 等饮食模式会影响体重,心血管疾病和糖尿病.
- 包括宏观营养素来源在内的这些饮食模式与慢性阻塞性肺病 (COPD) 之间的具体关系尚不清楚.
研究的目的:
- 研究坚持低碳水化合物饮食 (LCD) 和低脂肪饮食 (LFD) 与COPD患病率之间的关联.
- 检查液晶屏幕和液晶屏幕和LFD之间的关系以及被诊断患有COPD的个体中所有原因的死亡率.
主要方法:
- 利用了2007-2012年周期国家健康和营养检查调查 (NHANES) 的数据.
- 采用多变量逻辑回归来评估饮食得分与COPD几率之间的关联.
- 应用多变量Cox比例危险回归和受限立方线回归 (RCS) 来分析COPD患者的饮食得分和全因死亡率.
主要成果:
- 不健康的LFD得分与患上COPD的几率增加有关.
- 较高的不健康LCD得分与COPD患者总死亡风险显著增加有关.
- 相反,较高的健康LFD得分与COPD患者的总死亡率风险显著降低有关.
结论:
- 饮食模式在COPD风险和结果中起着重要作用.
- 促进健康的低脂肪饮食模式可能有利于降低COPD患者的死亡率.
- 对这些饮食模式中的特定宏观营养素来源进行进一步的研究对于COPD管理是有必要的.
