Narrative objectives1

This study aims to systematically organize intervention studies on the food environment conducted among Japanese adults, focusing on the intervention sites, target populations, intervention content, evaluation indicators, and reported outcomes. By examining the relationship between the food environment and outcomes such as eating behaviors, dietary awareness, food and nutrient intake, urinary sodium-to-potassium ratio, and food sales volume and revenue, this study will identify characteristics of food environment intervention studies in Japan and to clarify future research priorities.
