Study Tracks Rise Of New Type 1 And 2 Diabetes Cases In U.S. Youth
The SEARCH for Diabetes in Youth study is the first to estimate trends for new cases of type 1 and 2 diabetes in people under 20 years of age.
The study targeted youths from five racial-ethnic groups in the U.S.: Non-Hispanic whites, non-Hispanic blacks, Hispanics, Asian Americans/Pacific Islanders, and Native Americans. However, the Native American data cannot be generalized nationwide since those participating are not representative of all Native American youth.
Overall, it was discovered that from 2002 to 2012, newly diagnosed cases of type 1 diabetes rose by about 1.8 percent every year, while new type 2 diabetes cases increased more rapidly, by 4.8 percent.
“Because of the early age of onset and longer diabetes duration, youth are at risk for developing diabetes related complications at a younger age,” said Giuseppina Imperatore, M.D., Ph.D., epidemiologist in CDC's National Center for Chronic Disease Prevention and Health Promotion. “This profoundly lessens their quality of life, shortens their life expectancy, and increases health care costs.”
Among those aged 0 to 19, newly diagnosed cases of type 1 diabetes rose the most in Hispanic youth (4.2 percent annually), followed by non-Hispanic blacks (2.2 percent), and non-Hispanic whites (1.2 percent). Across all the groups studied, there were more new cases of type 1 in males than females.
Among those aged 0 to 19, newly diagnosed cases of type 2 diabetes rose the most in Native Americans (8.9 percent), followed by Asian Americans/Pacific Islanders (8.5 percent), and non-Hispanic blacks (6.3 percent). Across all the groups studied, there were more new cases of type 2 in females than males.
In youths aged 10 to 19, new cases of type 2 diabetes increased 3.1 percent among Hispanics; the smallest increase being among whites (0.6 percent).
“The differences among racial and ethnic groups and between genders raise many questions,” said Barbara Linder, M.D., Ph.D., of NIH's National Institute of Diabetes and Digestive and Kidney Diseases. “We need to understand why the increase in rates of diabetes development varies so greatly and is so concentrated in specific racial and ethnic groups.”
The SEARCH study was funded by the Centers for Disease Control and Prevention, and the National Institutes of Health.
