Abstract

Timing of eating (TOE) and energy intake (TOEI) has important implications for chronic disease risk beyond diet quality. The 2020 Dietary Guidelines Advisory Committee recommended developing consistent terminology to address the lack of TOE/TOEI standardization. The primary objective of this methodological systematic review was to characterize the conceptualization and assessment of TOE/TOEI within the chronic disease literature (International Prospective Register of Systematic Reviews registration number: CRD42021236621). Literature searches in Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus, Embase, PubMed, and Scopus were limited to English language publications from 2000 to August 2022. Eligible studies reported the association between TOE/TOEI and obesity, cardiovascular disease, type 2 diabetes mellitus, cancer, or a related clinical risk factor among adults (≥19 y) in observational and intervention studies. A qualitative synthesis described and compared TOE/TOEI conceptualization, definitions, and assessment methods across studies. Of the 7579 unique publications identified, 259 studies (observational [51.4 %], intervention [47.5 %], or both [1.2 %]) were eligible for inclusion. Key findings indicated that most studies (49.6 %) were conducted in the context of obesity and body weight. TOE/TOEI variables or assigned conditions conceptualized interrelated aspects of time and eating or energy intake in varying ways. Common TOE/TOEI conceptualizations included the following: 1) timepoint (specific time to represent when intake occurs, such as time of breakfast [74.8 %]); 2) duration (length of time or interval when intake does/does not occur, such as “eating window” [56.5 %]); 3) distribution (proportion of daily intake at a given time interval, such as “percentage of energy before noon” [29.8 %]); and 4) cluster (grouping individuals based on temporal ingestive characteristics [5.0 %]). Assessment, definition, and operationalization of 24-h TOE/TOEI variables varied widely across studies. Observational studies most often used surveys or questionnaires (28.9 %), whereas interventions used virtual or in-person meetings (23.8 %) to assess TOE/TOEI adherence. Overall, the diversity of terminology and methods solidifies the need for standardization to guide future research in chrononutrition and to facilitate inter-study comparisons.

24 小时进食和能量摄入时间的概念化和评估:慢性病文献的方法学系统回顾。
进食时间(TOE)和能量摄入(TOEI)除了对膳食质量有影响外,还对慢性疾病风险有重要影响。2020 年膳食指南咨询委员会 (DGAC) 建议制定统一的术语,以解决 TOE/TOEI 标准化不足的问题。本方法学系统综述的主要目的是描述慢性病文献(PROSPERO 注册号:CRD42021236621)中 TOE/TOEI 的概念化和评估特征。在 CINAHL Plus、Embase、PubMed 和 Scopus 中进行的文献检索仅限于 2000 年至 2022 年 8 月期间的英文出版物。符合条件的研究报告了观察性和干预性研究中 TOE/TOEI 与肥胖、心血管疾病 (CVD)、糖尿病 (T2DM)、癌症或成人(≥19 岁)中相关临床风险因素之间的关系。一项定性综述描述并比较了不同研究中 TOE/TOEI 的概念、定义和评估方法。在已确定的 7579 篇出版物中,有 259 项研究(观察性研究 [51.4%]、干预性研究 [47.5%] 或两者皆有 [1.2%])符合纳入条件。主要结果表明,大多数研究(49.6%)都是针对肥胖和体重进行的。TOE/TOEI变量或指定条件以不同的方式将时间与进食或能量摄入(EI)相互关联的方面概念化;常见的TOE/TOEI概念化包括1) 时间点(摄入发生的具体时间,如早餐时间[74.8%]);2) 持续时间(摄入发生/不发生的时间长度或时间间隔,如 "进食窗口"[56.5%]);3) 分布(特定时间间隔内每日摄入量的比例,如 "正午前能量摄入百分比"[29.8%]);以及 4) 聚类(根据时间摄入特征对个体进行分组[5.0%])。不同研究对二十四小时(24hr)TOE/TOEI 变量的评估、定义和操作差异很大。观察性研究最常使用调查或问卷(28.9%),而干预性研究则使用虚拟或面对面会议(23.8%)来评估 TOE/TOEI 的依从性。总之,术语和方法的多样性证明了标准化的必要性,以指导慢性营养学的未来研究,并促进研究间的比较。

期刊介绍: Advances in Nutrition (AN/Adv Nutr) publishes focused reviews on pivotal findings and recent research across all domains relevant to nutritional scientists and biomedical researchers. This encompasses nutrition-related research spanning biochemical, molecular, and genetic studies using experimental animal models, domestic animals, and human subjects. The journal also emphasizes clinical nutrition, epidemiology and public health, and nutrition education. Review articles concentrate on recent progress rather than broad historical developments. In addition to review articles, AN includes Perspectives, Letters to the Editor, and supplements. Supplement proposals require pre-approval by the editor before submission. The journal features reports and position papers from the American Society for Nutrition, summaries of major government and foundation reports, and Nutrient Information briefs providing crucial details about dietary requirements, food sources, deficiencies, and other essential nutrient information. All submissions with scientific content undergo peer review by the Editors or their designees prior to acceptance for publication.
