背景营养摄入不足被认为是脆弱的一个组成部分，但这一假设很少被研究。我们研究了低能量和营养摄入与虚弱之间的关系。我们使用的数据来自802名年龄在65岁或以上的人参加了InCHIANTI（Invecchiare in Chianti，Chianti地区的老龄化）研究。虚弱的定义是至少有两个以下标准：低肌肉力量，疲惫的感觉，低步行速度，减少体力活动。欧洲癌症和营养前瞻性调查（EPIC）问卷用于估计每日能量和营养素的摄入量。低摄入量定义为对应于能量和特定营养素的最低性别特定摄入量五分位数的值。采用校正的logistic回归分析研究虚弱和虚弱标准与能量和营养素摄入量低的关系。每日能量摄入
Background. Poor nutrient intake is conceptualized to be a component of frailty, but this hypothesis has been little investigated. We examined the association between low energy and nutrient intake and frailty.Methods. We used data from 802 persons aged 65 years or older participating to the InCHIANTI (Invecchiare in Chianti, aging in the Chianti area) study. Frailty was defined by having at least two of the following criteria: low muscle strength, feeling of exhaustion, low walking speed, and reduced physical activity. The European Prospective Investigation into Cancer and nutrition (EPIC) questionnaire was used to estimate the daily intake of energy and nutrients. Low intake was defined using the value corresponding to the lowest sex-specific intake quintile of energy and specific nutrients. Adjusted logistic regression analyses were used to study the association of frailty and frailty criteria with low intakes of energy and nutrients.Results. Daily energy intake
