Decreased sleep quality in patients with type 2 diabetes can interfere their daytime functions, alterations in emotions and decrease their quality of life. Relationship between sleep quality and self-care management among diabetes type 2 patients were examined. We used cross-sectional methods following with questionnaire of patient characteristic, Pittsburgh sleep quality index, perceived stress scale, diabetes self-management questionnaire and family support. This research has been conducted in 152 diabetes type 2 patients who were divided into 79 respondents without diabetic foot ulcers and 73 respondents with diabetic foot ulcers. Result of this study showed that 63.2% of respondents had poor sleep quality, 59.2% mild stress, 57.2% poor family support and 56.6% good diabetes self-management behavior. There was a significant relationship between sleep quality, duration of diabetes mellitus, and stress with diabetes self-care management (p: 0.013; p: 0.009; p: 0.007). There was no significant relationship between age, sex, education level, family support and diabetic ulcers with diabetes self-management care. In order to increase diabetes self-care management among diabetic patients, sleep quality need to be improved. Improvement can be made by controlling their blood glucose and providing better environment of sleep.
