本研究旨在评估食欲对有代表性的自由生活的台湾老年人死亡率的预测能力。1999-2000年期间，共有1856名年龄在65岁或以上的老年人营养和健康调查参与者完成了一份更大的问卷调查中的食欲问题。通过基线面对面访谈以及24小时饮食回忆和简化的食物频率问卷（提供饮食多样性评分和食物摄入频率）获得个人信息。从死亡登记处确定生存率，直至2008年12月31日。食欲不佳的参与者饮食多样性评分（DDS）较低，肉类，鱼类和海鲜，鸡蛋，蔬菜和水果的摄入频率较低，能量，蛋白质，维生素B-1，烟酸，铁和磷酸盐的摄入量也较低。与食欲良好的人相比，食欲一般和食欲差的人全因死亡的风险更高，风险比（HR）（95%置信区间，CI）分别为1.28（1.03-1.58）和2.27（1.71-3.02）。校正混杂因素后，HR（95%CI）分别为1.05（0.83-1.33）和1.50（1.03-2.18）。随着DDS或一般健康状况的进一步调整，这些HR变得不显著。与“DDS > 4且食欲良好”作为参照相比，“DDS 4且食欲不振”的联合HR（95%CI）为1.77（1.04-3.00）。食欲不振与较低的食物和营养摄入量有关，是台湾老年人死亡的独立风险。总之，食欲是独立的，介导的一般健康和调节饮食质量在其预测能力的死亡率。(C)2014爱思唯尔有限公司版权所有。
This study aimed to assess the predictive ability of appetite for mortality among representative free-living Taiwanese older adults. A total of 1856 participants aged 65 years or over from the Elderly Nutrition and Health Survey during 1999-2000 completed an appetite question in a larger questionnaire. Personal information was obtained by face-to-face interview at baseline, together with a 24-hour dietary recall and simplified food frequency questionnaire which provided a dietary diversity score and food intake frequency. Survivorship was ascertained from the Death Registry until December 31, 2008. Participants with a poor appetite had lower dietary diversity scores (DDS) and intake frequencies of meat, fish and sea food, egg, vegetable and fruit intake, along with lower energy, protein, vitamin B-1, niacin, iron and phosphate intakes. Those who had fair and poor appetites had a higher risk of all-cause mortality compared to those with good appetite, with hazard ratios (HR) (95% confidence interval, CI) of 1.28 (1.03-1.58) and 2.27 (1.71-3.02), respectively. After adjustment for confounders, the HRs (95% CI) were 1.05 (0.83-1.33) and 1.50 (1.03-2.18), respectively. With further adjustment for DDS or general health these HRs became non-significant. The joint HR (95% CI) for "DDS 4 and poor appetite" was 1.77 (1.04-3.00) compared to "DDS > 4 and good appetite" as referent. Poor appetite is associated with lower food and nutrient intakes and an independent risk for mortality in older Taiwanese. In conclusion, appetite is separate, mediated by general health and modulated by dietary quality in its predictive capacity for mortality. (C) 2014 Elsevier Ltd. All rights reserved.
