Utilizing a Stepped Wedge Cluster Randomized Study Design in Nutrition Research: A Case Study describing a Clinical Trial of Protected Mealtimes

Research output: Other contributionOtherpeer-review


The stepped-wedge cluster randomized controlled trial has strengths that align particularly well with nutrition research. This case study describes key issues and fundamental decisions that should be considered in developing the trial protocol, highlighting particular aspects of a trial where Protected Mealtimes was implemented. These issues include defining the unit of the cluster, the approach(es) to randomization, limiting bias, and seeking relevant ethics approvals. The success of the research design used in this study suggests that its use within nutrition and other public health settings will increase into the future.
