1 . Rahul Aggarwal was in medical school when he got the surprising news that his mother-a fit woman in her 40s-had been diagnosed with type2 diabetes (糖尿病). “I always thought of diabetes as a disease of people at higher weights and with certain lifestyle practices.” he recalls, “but my mom was an Indian American woman with a healthy weight and good diet and exercise practices.”
Aggarwal, now a clinical fellow at Beth Israel Deaconess Medical Center in Boston began thinking about how diabetes seems to affect certain ethnic and racial groups. It quantified diabetes risk in minority groups to determine if current screening recommendations are correct and equal.
The current standard was released in 2021 by the U. S. Preventive Services Task Force (USPSTF), which issues evidence-based guidance on disease prevention. The recommendation is to test adults aged 35 to 70 for diabetes if they are overweight or obese, defined as having a body mass index (BMI)of 25 kg/m2 or more. Aggarwal and his cooperators looked at the lowest-risk individuals qualified to screen under that rubric(评价量规). The researchers were shocked to find that the rate was about double for Hispanics and even higher among Black and Asian Americans. They concluded that to detect diabetes equally across all these groups, you would need to test Asian Americans with a BMI of 20 and Black and Hispanic individuals with a BMI of just 18. 5-measures considered to be in the healthy range.
Ngo-Metzger, who was the USPSTFs scientific director from 2012 to 2019, notes that “most studies of diabetes were done in middle-aged white individuals,” She argues that they ‘should be revised. “The study found that you would miss so many Blacks, Hispanics and Asians when you use these guidelines. I think it’s a kind of harm.”
