A Systematic Review of Effect Modification in Trials of Behavioral Interventions to Increase Fruit and Vegetable Consumption

Although the health benefits of fruit and vegetable consumption (FVC) has been well documented, the evidence supporting the effectiveness of behavioral interventions to increase FVC has not been as consistent. This review aimed to identify individual and environmental level factors that may explain systematic differences in treatment effects in randomized controlled trials(RCTs) of behavioral interventions to increase FVC through effect modification (EM) and discusses the utility of examining EM in the context of a RCT.
