We investigated the association of adherence to the Dietary Approaches to Stop Hypertension (DASH) diet with all-cause mortality in patients with a history of heart failure.
We analyzed data from the National Health and Nutrition Examination Survey (NHANES). Dietary information was obtained from a 24-h dietary recall interview. Adherence to the DASH diet was assessed using the DASH score. The primary outcome was all-cause mortality which was confirmed by the end of 2011. Weighted Cox proportional hazards regression models were used to determine the hazard ratios and 95% CI for the association of the DASH score and all-cause mortality with multivariate adjustment.
The median DASH score was 2 among the 832 study participants. There were 319 participants who died after a median follow-up duration of 4.7 years. A higher DASH score (>2 vs. ≤ 2) was not associated with a decrease in the risk of all-cause mortality (adjusted HR 1.003, 95% CI 0.760-1.323, = 0.983). With respect to the components of the DASH score, a lower sodium intake was not associated with a decreased risk of mortality (adjusted HR 1.045, 95% CI 0.738-1.478, = 0.803).
A higher DASH score (>2 vs. ≤ 2) was not associated with all-cause mortality in patients with heart failure.
我们研究了坚持终止高血压膳食疗法（DASH 饮食）与心力衰竭病史患者全因死亡率之间的关联。
我们分析了美国国家健康与营养检查调查（NHANES）的数据。通过 24 小时饮食回顾访谈获取饮食信息。使用 DASH 评分评估对 DASH 饮食的依从性。主要结局是全因死亡率，截至 2011 年底得到确认。采用加权 Cox 比例风险回归模型确定 DASH 评分与全因死亡率关联的风险比及 95%置信区间，并进行多变量调整。
832 名研究参与者的 DASH 评分中位数为 2。在中位随访期 4.7 年后，有 319 名参与者死亡。较高的 DASH 评分（>2 与≤2）与全因死亡率风险降低无关（校正风险比 1.003，95%置信区间 0.760 - 1.323，P = 0.983）。关于 DASH 评分的组成部分，较低的钠摄入量与死亡率风险降低无关（校正风险比 1.045，95%置信区间 0.738 - 1.478，P = 0.803）。
较高的 DASH 评分（>2 与≤2）与心力衰竭患者的全因死亡率无关。
