Most of the tools used to assess nutritional intake in large epidemiological studies were originally developed to be used in young and middle-aged subjects and, therefore, their validity and reliability when employed in older subjects remain uncertain. We conducted this study to verify whether the questionnaire developed in the context of the European Prospective Investigation into Cancer and nutrition (EPIC) could be used to assess dietary intake in the participants of InCHIANTI, an epidemiological study of risk factors for disability in late life, performed in 633 men (78% aged, > or =65 years) and 802 women (81% aged, > or =65 years) randomly sampled from the general population. In particular, the aim of this project was to collect preliminary information that could support a future study of concurrent validity. Data on food consumption assessed using the EPIC questionnaire from the InCHIANTI participants were compared with those collected using a 7-day diary in the National Nutritional Investigation into Dietary Behavior (INN-CA), a study conducted in 15 Italian centres aimed at assessing Italian households' and individuals' dietary intake. In spite of different populations and different methods used in data collection, the distributions of dietary intake from the two studies were remarkably similar for most macro- and micro-nutrients, both in men and women and according to age groups. At a population level, a food frequency questionnaire and a costly and time-consuming objective method provided similar estimates of dietary intake. Future study should attempt to generalize these findings at an individual level by collecting data with both instruments in the same subjects.
大多数用于大型流行病学研究中评估营养摄入量的工具最初是为年轻和中年受试者开发的，因此，当用于老年受试者时，其有效性和可靠性仍不确定。我们开展这项研究，以验证在欧洲癌症与营养前瞻性调查（EPIC）背景下开发的问卷是否可用于评估基安蒂衰老纵向研究（InCHIANTI）参与者的饮食摄入量。InCHIANTI是一项关于晚年残疾风险因素的流行病学研究，从普通人群中随机抽取了633名男性（78%年龄≥65岁）和802名女性（81%年龄≥65岁）。具体而言，该项目的目的是收集初步信息，以支持未来关于同时效度的研究。将InCHIANTI参与者使用EPIC问卷评估的食物消费数据，与在意大利全国饮食行为营养调查（INN-CA）中使用7天饮食日记收集的数据进行比较。INN-CA是一项在15个意大利中心开展的研究，旨在评估意大利家庭和个人的饮食摄入量。尽管两项研究的人群不同，数据收集方法也不同，但在男性和女性以及不同年龄组中，大多数常量营养素和微量营养素的饮食摄入量分布非常相似。在人群层面，食物频率问卷和一种成本高且耗时的客观方法对饮食摄入量的估计相似。未来的研究应尝试通过在同一受试者中使用这两种工具收集数据，在个体层面推广这些发现。
