BACKGROUND
Limited research has evaluated the relationship between dietary behavior and mortality among those with mobility limitations.
OBJECTIVE
To examine the association between dietary behavior and mortality in a national sample of American adults with mobility limitations.
METHODS
Data from the 2003-2006 National Health and Nutrition Examination Survey were utilized. Participants were followed through 2011. Based on self-report, analyzed participants included those with mobility limitations (N = 1369). Dietary behavior was assessed from the alternate healthy eating index (AHEI).
RESULTS
For the sample, 108,010 person-months occurred with an all-cause mortality rate of 2.07 per 1000 person-months. Dietary behavior was associated with reduced all-cause mortality risk when expressed both as a continuous variable and binary variable (i.e., meeting dietary guidelines). With regard to the latter, and after adjustments, those meeting dietary guidelines (vs. not) had a 40% reduced hazard of all-cause death (HR = 0.60; 95% CI: 0.38-0.97; P = 0.03).
CONCLUSION
Among adults with mobility limitations, and thus, who unable to engage in sufficient physical activity, dietary behavior may have survival benefits.
背景
有限的研究评估了有行动障碍者的饮食行为与死亡率之间的关系。
目的
在有行动障碍的美国成年人的全国样本中，研究饮食行为与死亡率之间的关联。
方法
利用了 2003-2006 年国家健康与营养调查的数据。参与者随访至 2011 年。根据自我报告，分析参与者包括有行动障碍者（N=1369）。饮食行为通过替代健康饮食指数（AHEI）进行评估。
结果
对于该样本，共发生 108010 人月，全因死亡率为每 1000 人月 2.07 人。饮食行为与全因死亡率风险降低相关，无论是以连续变量还是二分类变量（即，符合饮食指南）表示。关于后者，在调整后，符合饮食指南（vs. 不符合）者的全因死亡风险降低了 40%（HR=0.60；95%CI：0.38-0.97；P=0.03）。
结论
在有行动障碍的成年人中，由于无法进行足够的身体活动，饮食行为可能具有生存益处。
