Type 1 diabetes mellitus (TDM) is a chronic autoimmune disease. that affected carbohydrate metabolism and caused by insulin insufficiency resulting in increased blood glucose. It's one of the most common endocrine and metabolic conditions in childhood. There's 9 million people live with T1DM worldwide according to International Diabetes Federation. In Egypt, 1 in 98 families are impacted and the disease is growing at 6.7% each year. Living with T1DM has been associated with a significant impact on a person's social, mental, and psychological quality of life (QoL). as the individual must adopt blood glucose monitoring, use of injections or diabetes technology for insulin regulation, diet restrictions, and exercise. Also, there's increased risk of developing micro-and macro-vascular complications that result in morbidity and mortality in Long-term uncontrolled DM. therefore, these children and adolescents with T1DM have an increased risk of psychiatric comorbidities like depression, anxiety and sleep disorders, depression is one of the most common disorders. They appear to have a greater incidence of depression, anxiety and poor health-related quality of life (HRQoL) compared to their healthy peers.
