Even though the significance of biopsychological factors in the mental health status of T2DM patients has been discussed in other studies, the role of environmental factors has been lacking. Therefore, this review aimed to identify the relationship between environmental factors and mental health status among T2DM patients. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews was utilized in this study. Using predetermined keywords, a systematic search was conducted on three electronic databases from 2005 to 2023, namely, Web of Science, Scopus, and PubMed. Articles written in English, and studies focusing on the research question are among the inclusion criteria. Ten articles were extracted that were relevant to the research question. Results: Poor socioeconomic status, urban areas, the influence of neighborhood, greenness, and air pollution had associations with mental health status among T2DM patients. Conclusion: The possible implications of these factors for mental health demand further research and policy consideration. https://ijph.tums.ac.ir/index.php/ijph/article/view/30370 https://ijph.tums.ac.ir/index.php/ijph/article/download/30370/8334
