Diabetes mellitus is a disease that in recent decades has shown progressive increase in its incidence and prevalence worldwide, In the us from 2006 to 2011 the incidence of this disease has increased as this scientific article says, "Among nearly 7 million adults aged 20 years or older, we estimated annual diabetes incidence per 1,000 persons overall and by age, sex, race/ethnicity, and body mass index. We identified 289,050 incident cases of diabetes. Age- and sex-adjusted population incidence was stable between 2006 and 2010, ranging from 10.3 per 1,000 adults (95% confidence interval (CI): 9.8, 10.7) to 11.3 per 1,000 adults (95% CI: 11.0, 11.7). Adjustedincidence was significantly higher in 2011 (11.5, 95% CI: 10.9, 12.0) than in the 2 years with the lowest incidence. A similar pattern was observed in most prespecified subgroups, but only the differences for persons who were not white were significant. In 2006, 56% of incident cases had a glycated hemoglobin (hemoglobin A1c) test as one of the pair of events identifying diabetes. By 2011, that number was 74%. In conclusion, overall diabetes incidence in this population did not significantly increase between 2006 and 2010, but increases in hemoglobin A1c testing may have contributed to rising diabetes incidence among nonwhites in 2011" [ CITATION Nic15 l 1033 ]. According to this information, the numbers of patients with diagnosed diabetes has increased between 2010 and 2012. Most of this cases are people older than twenty age old. This data tell us that the adult population in the US is more tended to develop diabetes. The factors of developing diabetes can be different for each person. To explain what those factors are, the characteristics of this disease such as risk factors, treatments, type and why this disease is recognized as the seventh cause of death in the US according to the American Diabetes Association.
