Then, the database-based publication volume and research hotspots were visually analyzed and found that the upward trend is more prominent in the United States, the research hotspots of the three databases were consistent with the themes of the health and nutrition survey. Finally, the construction and application of the databases were discussed and recommendations were made, which was expected to provide a path for relevant researches and better encourage the generation of scientific evidence.
