Research Project: Evidence Map on the Relationship Between Exposure to Dietary Sweetness and Body Weight-Related Outcomes in Adults

Location: Food Components and Health Laboratory

Project Number: 8040-51530-011-019-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Jul 1, 2021
End Date: Jun 30, 2022

Dietary recommendations from numerous governmental and health organizations recommend reduced intake of added sugars due to the health risks associated with excess energy from sugars, including the risk of overweight and obesity. The association between sugar intake and excess body weight may be mediated by the ease with which excess energy can be consumed from added sugars in an ad libitum diet. Before a conclusion on the association between dietary sweetness and body weight can be determined, it is necessary to determine the availability of evidence in the published literature. The objective of this project is to prepare an evidence map to characterize the evidence on the association between dietary sweetness and body weight related outcomes, determine whether evidence is sufficient to support a systematic evidence review, and identify future research priorities.

An evidence map is a systematic search of the literature to determine the number and characteristics of the studies on a particular topic and includes the identification of future research needs. This evidence is then compiled into a tabular database and/or visual figure or graph. This review will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews and will follow the Joanna Briggs Institute scoping review framework. There are no criteria for how the results from an evidence map are presented, so we will use previous evidence maps as guides for presenting the results. This evidence map will be registered in the Systematic Review Data Repository and will be linked to a registration on the Open Science Framework Registries. We will adopt The Center for Open Science’s Transparency and Openness Promotion Guidelines and provide developed data as open access.
