介绍创新技术的使用被认为是在各种研究环境中改善饮食评估。然而，在营养流行病学研究中，这些方法的相对优势仍有待于评估，因为这些研究需要对个体水平的日常摄入量进行准确的定量估计。目的报告现有的膳食评估创新技术的清单，并与传统方法相比，批判性地评估其优缺点（即食品频率表，食品记录，24小时饮食召回）在流行病学研究中使用。方法一个列表，目前可用的技术，确定从英文期刊，使用PubMed和Web的科学。检索标准主要是基于出版日期（1995年至2011年）和预定义的搜索keywords.Results六个主要组的创新技术被确定（“个人数字助理”，“移动电话”，“交互式计算机”，“网络”，“照相机和录音机”和“扫描和传感器为基础的”技术）。与传统的食物记录相比，个人数字助理和移动的电话设备似乎通过“实时”记录进食事件的可能性来改善记录，但它们估计个人饮食摄入量的有效性低至中等。在24小时饮食回忆中，关于全自动方法的准确性的知识仍然有限;方法学问题，例如自我报告的部分大小的不准确性可能比基于访谈的应用程序更重要。相比之下，在创新的网络为基础的，并在传统的纸为基础的食物频率questionires的测量误差是最有可能相似的，这表明基本的方法是不变的technology.Conclusions饮食评估的新技术大多被认为有重叠的方法学功能与传统的方法主要用于营养流行病学。它们加强膳食评估的主要潜力是通过更具成本效益和时间效益、更省力的数据收集方式和更高的受试者接受度，尽管将其纳入流行病学研究需要额外的考虑因素，如研究目标、目标人群和可用的财政资源。然而，即使在创新技术中，与自我报告的饮食摄入量相关的固有个体偏差也不会得到解决。因此，更多的研究对于调查创新饮食评估技术的有效性至关重要。
Introduction The use of innovative technologies is deemed to improve dietary assessment in various research settings. However, their relative merits in nutritional epidemiological studies, which require accurate quantitative estimates of the usual intake at individual level, still need to be evaluated.Objective To report on the inventory of available innovative technologies for dietary assessment and to critically evaluate their strengths and weaknesses as compared with the conventional methodologies (i.e. Food Frequency Questionnaires, food records, 24-hour dietary recalls) used in epidemiological studies.Methods A list of currently available technologies was identified from English-language journals, using PubMed and Web of Science. The search criteria were principally based on the date of publication (between 1995 and 2011) and pre-defined search keywords.Results Six main groups of innovative technologies were identified ('Personal Digital Assistant-', 'Mobile-phone-', 'Interactive computer-', 'Web-', 'Camera- and tape-recorder-' and 'Scan- and sensor-based' technologies). Compared with the conventional food records, Personal Digital Assistant and mobile phone devices seem to improve the recording through the possibility for 'real-time' recording at eating events, but their validity to estimate individual dietary intakes was low to moderate. In 24-hour dietary recalls, there is still limited knowledge regarding the accuracy of fully automated approaches; and methodological problems, such as the inaccuracy in self-reported portion sizes might be more critical than in interview-based applications. In contrast, measurement errors in innovative web-based and in conventional paper-based Food Frequency Questionnaires are most likely similar, suggesting that the underlying methodology is unchanged by the technology.Conclusions Most of the new technologies in dietary assessment were seen to have overlapping methodological features with the conventional methods predominantly used for nutritional epidemiology. Their main potential to enhance dietary assessment is through more cost- and time-effective, less laborious ways of data collection and higher subject acceptance, though their integration in epidemiological studies would need additional considerations, such as the study objectives, the target population and the financial resources available. However, even in innovative technologies, the inherent individual bias related to self-reported dietary intake will not be resolved. More research is therefore crucial to investigate the validity of innovative dietary assessment technologies.
