ABSTRACT Introduction: Diabetes mellitus being a chronic metabolic disease responds well to selfcare practices. Improper self-care and insomnia have been associated with poor glycemic status with its associated micro and macrovascular complications. Materials and methods: The data regarding self-care and insomnia were collected from 90 consecutive adult patients with type 2 diabetes at a tertiary care teaching hospital, using Diabetes Self-Management Questionnaire and Insomnia Severity Index questionnaire. Glycated haemoglobin was used as a measure of glycemic status. Results: There was a significant association between poor self-care with insomnia (p=0.001) and glycemic status (p=0.03), but there was no association between insomnia and glycemic status (0.95). Conclusion: Poor self-care is associated with poor glycemic status and insomnia.
