Type 1 Diabetes - Epidemiology Forecast to 2029
Type 1 Diabetes (T1D), formerly referred to as insulin-dependent diabetes, is a type of diabetes that predominantly develops in children or young adults before the age of 40 years. The condition, therefore, was also referred to as juvenile diabetes. T1D accounts for about 5-10% of all diabetes cases and occurs as a result of the autoimmune destruction of pancreatic beta cells, which are responsible for producing insulin, a hormone that regulates blood sugar. If the condition is left untreated, blood sugar levels accumulate. In addition to the pancreas, high levels of blood sugar can damage other major organs such as the heart, blood vessels, nerves, eyes, and kidneys. Such damage can be life threatening; thus, T1D has an immense impact on the physical, psychological, and social well-being of patients. Furthermore, research suggests that the incidence of T1D is increasing globally, which may lead to an increased burden on healthcare resources (Holt, 2004; World Health Organization, 2013; Mayo Clinic, 2020).
In the 8MM, the diagnosed prevalent cases of T1D will increase from 3,329,294 cases in 2019 to 3,921,695 cases in 2029, at an Annual Growth Rate (AGR) of 1.78% per year. Among the 8MM, the US had the highest number of diagnosed prevalent cases of T1D in 2019 and 2029, at 1,719,922 cases and 1,880,013 cases, respectively. Canada had the lowest number of prevalent cases of T1D in 2019 and 2029, at 146,616 cases and 202,325 cases, respectively. GlobalData epidemiologists attribute the increase in the diagnosed prevalent cases of T1D in the 8MM to population changes as well as an increased trend in prevalence. However, further research is necessary to clearly understand the epidemiological factors responsible for the growth in the prevalent cases of T1D (Onkamo et al., 1999).
