摘要 饮食指南应以饮食与健康之间关系的最佳现有证据为基础，包括来自基于营养、基于食物和饮食模式研究的证据。本研究的主要目的是分析系统评价，以便根据膳食暴露情况为 2013 年澳大利亚膳食指南提供信息。第二个目的是根据健康结果和纳入研究的设计来分析评论。为了确定系统评价，以膳食指南报告为起点并检索了相关参考文献。证据报告包含本分析中使用的数据。描述性统计用于根据纳入研究的暴露、结果和设计来分析评论。该分析共纳入 143 项系统评价。食物是最常见的暴露内容（86·7 % 的评论），其次是营养素（10·5 %）和饮食模式（2·8 %）。慢性病发病率和/或死亡率是最常见的结果 (80·4 %)，其次是慢性病危险因素 (19·6 %)。大多数评论包括来自队列或巢式病例对照研究的证据（92·3%），许多评论包括来自病例对照研究的证据（61·5%），一些包括来自随机对照试验的证据（28·7%）。这些结果反映了所提出的研究问题、所使用的系统评价方法以及可用的证据。在制定澳大利亚膳食指南的未来版本时，有机会回顾膳食模式研究的最新证据。
Abstract Dietary guidelines should be underpinned by the best available evidence on relationships between diet and health, including evidence from nutrient-based, food-based and dietary patterns research. The primary aim of the present study was to analyse the systematic reviews conducted to inform the 2013 Australian Dietary Guidelines according to dietary exposure. The secondary aim was to analyse the reviews by health outcome, and design of included studies. To identify the systematic reviews, the dietary guidelines report was used as a starting point and relevant references were retrieved. The evidence report contained the data used in this analysis. Descriptive statistics were used to analyse reviews according to exposure, outcome, and design of included studies. A total of 143 systematic reviews were included in this analysis. Foods were the most common exposure (86·7 % of reviews), followed by nutrients (10·5 %) and dietary patterns (2·8 %). Chronic disease morbidity and/or mortality was the most common outcome (80·4 %), followed by chronic disease risk factors (19·6 %). Most reviews included evidence from cohort or nested case–control studies (92·3 %), many included evidence from case–control studies (61·5 %) and some included evidence from randomised controlled trials (28·7 %). These results reflect the research questions that were asked, the systematic review methods that were used, and the evidence that was available. In developing future iterations of the Australian Dietary Guidelines, there is an opportunity to review the latest evidence from dietary patterns research.
