Background: Diabetes has long-term complications and therefore affects the health of the community in addition to the individual.

The statistical population included all middle-aged patients with diabetes who were referred to the endocrinologists of Bushehr province in 2019, among whom 195 people were selected by the available sampling method. Data obtained by SF-36 Health-Related Quality of Life Questionnaire, Diabetes self-care questionnaire, Pittsburgh Sleep Quality Questionnaire, and Mental Well-Being Scale. The data were analyzed using the path analysis method using SPSS.22 and Amos.22 software. Results: The results showed that both the variables of sleep quality and mental well-being through self-care had a direct and significant relationship with quality of life (p <0.001). The direct relationship between sleep quality and quality of life was not significant. But there was a significant direct relationship between mental well-being and quality of life (p <0.001). Conclusion: It can be concluded that sleep quality and mental well-being affect the self-care that the patient chooses, they can predict the quality of life of diabetic patients.
