A scoping review of 52 studies looked at how "digital nudging" can influence health behaviors. These interventions include one-way messages, peer interactions, and self-nudging delivered through mobile apps, websites, chatbots, and voice systems. The goal was to see how these tools could support pillars like nutrition, sleep, and addiction management.
The review found that while digital nudges are being used in many areas, most current research focuses on nutrition and physical activity. These two areas made up more than three-quarters of the studies reviewed. The findings suggest that technology can be a helpful tool for encouraging positive lifestyle changes.
Because this was a scoping review, it highlights potential rather than proving exactly how well specific nudges work in clinical practice. Many of the included studies were short-term and had limited diversity in the people who participated. These results show that while digital tools are promising, more research is needed to see their long-term effects.
