The number of patients with diabetes mellitus (DM) is increasing at an alarming rate. Global cases increased by 211 million between 2000 and 2013. It is predicted that there will be 210 million new cases of DM between 2013 and 2035. It is commonly assumed that type 2 diabetes mellitus (T2DM) mainly affects older adults. However, data demonstrate that among the 382 million individuals with DM in 2013, the greatest number of patients were younger adults, and, of 5.1 million deaths due to DM, half were younger adults.
The number of patients with DM is also increasing in Indonesia. Indonesia has the seventh largest number of patients with DM in the world, with nearly 11 million adults having been diagnosed with T2DM. The prevalence of DM in younger and older adults in Indonesia is similar, namely, 4.48% and 5.33%, respectively. Recently in Indonesia, the incidence of T2DM in younger adults has begun to rise.
DM has a significantly negative impact on health-related quality of life (HRQOL) in patients, either directly or because of its complications. Additionally, patients with DM tend to have poor HRQOL, especially in regard to physical and psychological functions.
