- Less than half of Asian Americans who ought to be screened for type 2 diabetes, miss it.
- Undiagnosed diabetes is almost three times higher among Asian Americans.
- Even at lower body weights, Asians are at high risk for type 2 diabetes.
A team of University of Chicago researchers found that only 47.1 percent of Asian Americans received appropriate screening, compared to 60.2 percent of non-Hispanic blacks, 59.2 percent of non-Hispanic whites, 58.8 percent of multiracial adults, 58.1 percent of Hispanics, 55.6 percent of American Indians or Alaskan Natives and 50.3 percent of Pacific Islanders.
‘Asian American overweight adults, those with a body mass index of 25 or more, should be screened even if they were younger than 45.’
Advertisement"Even after accounting for education, access to healthcare and other key factors, Asian Americans had 34 percent lower odds of being screened compared to non-Hispanic whites," said the study's lead author, Elizabeth Tung, MD, clinical instructor of medicine at the University of Chicago. "This may be an important driver of undiagnosed diabetes in this group."
The researchers analyzed data from the 2012-14 Behavioral Risk Factor Surveillance System, an annual telephone survey that collects information on health risks and preventive behaviors of United States residents. Their sample included 526,000 respondents, including 9,310 Asian Americans, who met the criteria for diabetes screening.
"Asian Americans are not necessarily averse to screening tests," said Tung. The researchers examined a subgroup of Asian Americans who completed both breast and colon cancer screening, and the lower rates of diabetes screening persisted. Both breast and colon cancer screening are "logistically and technically more involved than diabetes screening," the researchers note.
Many Asian patients and some of their physicians may not be fully aware that - even at lower body weights - Asians are at high risk for type 2 diabetes. About 21 percent of Asian Americans have type 2 diabetes, nearly double the rate for non-Hispanic whites. Undiagnosed diabetes is almost three times higher among Asian Americans.
Recognizing this increased risk, the American Diabetes Association (ADA) revised its screening guidelines for Asian Americans last year. They formerly recommended that Asian Americans should be screened if they were at least 45 years old. Overweight adults, those with a body mass index (BMI) of 25 or more, should be screened even if they were younger than 45.
In 2015, the ADA changed their guidelines to recommend screening for Asian Americans with a BMI of 23 or higher. "Asian Americans should confirm with their doctors that they have been screened for diabetes," Tung said. "Doctors shouldn't neglect to screen Asian Americans just because they appear to be thin."
