diabetes when BMI levels are lowered; they in fact may have a higher percentage of body fat which contributes to a greater risk of developing diabetes and other health concerns that are commonly overseen. Because of their BMIs, which are usually lower than other racial and ethnic groups, there is a common misconception that they are not at much of a risk for developing type 2 diabetes. The World Health Organization, however, has suggested a lower BMI cutoff point in order to properly diagnose obesity for Asian Americans because of such low BMI levels. Though it is expected that as there is a higher risk of type 2 diabetes within the Asian American population that much research is being done to screen for diabetes efficiently, the rate of not diagnosing type 2 diabetes for Asian Americans is three times as high as non-Hispanic whites. More than one in three people with diabetes are undiagnosed from improper screening, and this is particularly high for Asian Americans and Hispanics. A possible reason for why this may be the case is because Asian Americans are not aware of their elevated risk of developing type 2 diabetes and therefore refrain from screenings. Having no access to health insurance or lack of utilization of health care due to language barriers as Asian immigrants may also contribute to the lack of screenings and increased likelihoods of undiagnosed type two diabetes. Research on language barriers showed differences in diagnoses of diabetes for Asian Americans and Hispanics particularly compared to whites in America as clinicians are lacking physician-patient communication. Another possibility is that the existence of the "model minority myth" prevents physicians from recognizing that such an elevated risk exists in Asian Americans, along with other common health issues. Based on these possibilities, Chinese and Korean Americans are also less likely than other Asian American subgroups to take part in self-management practices for their diabetes while Asian Americans as a whole are not given the physician-led management resources to treat diabetes like other racial groups. In 2015, the American Diabetes Association (ADA) changed its guidelines for testing for diabetes for all Asian American adults who have a BMI of 23 or more instead of 25, which launched campaigns like "Screen at 23". Older Asian Americans have increased odds of diabetes or hypertension that still needs to be addressed. Hepatitis B Hepatitis B is especially prevalent amongst Asian Americans.
