Objective To summarize the best evidence on lifestyle management in the prediabetic population, and to provide a reference for medical staff to intervene in lifestyle for this population. Methods Using evidence-based nursing methods, two researchers independently extracted the evidence from domestic and foreign evidence-based resources and literature databases. They summarized the best evidence from the literature that met the quality evaluation. Results A total of 16 articles were included, consisting of 2 guidelines, 6 pieces of expert consensus, 6 systematic reviews, and 2 evidence summaries. A total of 30 pieces of evidence were extracted from 8 topics: lifestyle intervention goals, body quality management, diet management, exercise management, health education, sleep management, social support, and regular follow-up. Conclusion The best evidence summarized in this study can be used as a reference for healthcare professionals, prediabetic population and their family members in their lifestyle management. In the process of evidence translation, individual differences should be fully considered, and individualized life intervention plans should be formulated for patients.
