Abstract

Background: Collection of detailed dietary data is labor intensive and expensive, harmonization of existing data sets has been proposed as an effective tool for research questions in which individual studies are underpowered.

Methods: In this paper, we describe the methodology used to retrospectively harmonize nutritional data from multiple sources, based on the individual participant data of all available studies, which collected nutritional data in Israel between 1963 and 2014. This collaboration was established in order to study the association of red and processed meat with colorectal cancer. Two types of nutritional questionnaires, the Food Frequency Questionnaires (FFQ) and the 24-h dietary recall (24HR recall), and different food composition tables, were used by the participating studies. The main exposure of interest included type of meat (total meat, red meat, and poultry) and level of processing.

Results: A total of 29,560 Israeli men and women were enrolled. In studies using FFQ,the weighted mean intakes of total, red, processed meat, and poultry were 95, 27, 37 and 58 gr/day and 92, 25, 10, and 66 gr/day in studies using 24HR recall, respectively.. Despite several methodological challenges, we successfully harmonized nutritional data from the different studies.

Conclusions: This paper emphasizes the significance and feasibility of harmonization of previously collected nutritional data, offering an opportunity to examine associations between a range of dietary exposures and the outcome of interest, while minimizing costs and time in epidemiological studies.

统一七项历史研究营养数据的方法和挑战。
背景:收集详细的膳食数据既费力又昂贵:收集详细的膳食数据耗费大量人力和财力,因此,对于单项研究力量不足的研究问题,协调现有数据集被认为是一种有效的工具:在本文中,我们介绍了根据所有可用研究的个人参与者数据,对多个来源的营养数据进行回顾性协调的方法,这些研究在 1963 年至 2014 年期间在以色列收集了营养数据。这项合作是为了研究红肉和加工肉类与结直肠癌的关系。参与研究使用了两种营养问卷,即食物频率问卷(FFQ)和24小时饮食回忆(24HR recall),以及不同的食物成分表。主要研究对象包括肉类种类(全肉、红肉和禽肉)和加工程度:共有 29 560 名以色列男性和女性参加了研究。在使用 FFQ 的研究中,总肉、红肉、加工肉和家禽的加权平均摄入量分别为 95、27、37 和 58 克/天;在使用 24 小时回忆的研究中,总肉、红肉、加工肉和家禽的加权平均摄入量分别为 92、25、10 和 66 克/天。尽管在方法上存在一些挑战,但我们成功地协调了来自不同研究的营养数据:本文强调了统一以前收集的营养数据的意义和可行性,为研究一系列膳食暴露与相关结果之间的关系提供了机会,同时最大限度地减少了流行病学研究的成本和时间。

期刊介绍: Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
