摘要：Background: The rigor and integrity of the published research in nutrition studies has come into serious questionin recent years. Concerns focus on the use of flexible data analysis practices and selective reporting and the failureof peer review journals to identify and correct these practices. In response, it has been proposed that journalsemploy editorial procedures designed to improve the transparency of published research.Objective: The present study examines the adoption of editorial procedures designed to improve the reporting ofempirical studies in the field of nutrition and dietetics research.Design: The instructions for authors of 43 journals included in Quartiles 1 and 2 of the Clarivate Analytics’ 2018Journal Citation Report category Nutrition and Dietetics were reviewed. For journals that published original research,conflict of interest disclosure, recommendation of reporting guidelines, registration of clinical trials, registration ofother types of studies, encouraging data sharing, and use of the Registered Reports were assessed. For journals thatonly published reviews, all of the procedures except clinical trial registration were assessed.Results: Thirty-three journals published original research and 10 published only reviews. Conflict of interestdisclosure was required by all 33 original research journals. Use of guidelines, trial registration and encouragementof data sharing were mentioned by 30, 27 and 25 journals, respectively. Registration of other studies was requiredby eight and none offered Registered Reports as a publication option at the time of the review. All 10 reviewjournals required conflict of interest disclosure, four recommended data sharing and three the use of guidelines.None mentioned the other two procedures.Conclusions: While nutrition journals have adopted a number of procedures designed to improve the reporting ofresearch findings, their limited effects likely result from the mechanisms through which they influence analyticflexibility and selective reporting and the extent to which they are properly implemented and enforced by journals.
