A new screening method uses an unexpected body measurement to estimate diabetes risk without a blood test.<\/p>\n

Researchers have developed a free online screening tool that considers the length of a person\u2019s thigh alongside six more familiar health indicators. Called MEDWACS, the tool estimates the likelihood that an adult has prediabetes or undiagnosed type 2 diabetes without requiring laboratory testing.<\/p>\n

The unusual approach could help address a major blind spot in public health. About 115.2 million US adults have prediabetes, and roughly eight in 10 do not know it, according to the Centers for Disease Control and Prevention. Prediabetes often causes no clear symptoms, yet it raises the risk of developing type 2 diabetes, heart disease, and stroke.<\/p>\n

\u201cType 2 diabetes is easy to diagnose with a blood test, but if you don\u2019t suspect you have it, you won\u2019t go to the doctor to have one done. That\u2019s why an online test at home can encourage people to see a doctor,\u201d said Daniel Yoo, a postdoctoral researcher at DTU Sustain who led the project.<\/p>\n

The Research Team Behind MEDWACS<\/p>\n

Yoo created MEDWACS with DTU Professor Olivier Jolliet and Umberto Maggiore, an Italian physician and researcher at the University of Parma who specializes in kidney disease. Diabetes can damage the kidneys when elevated blood sugar harms their filtering system over time.<\/p>\n

Their peer-reviewed study was published in the Journal of Clinical Epidemiology.<\/p>\n

How the MEDWACS Test Works<\/p>\n

To use MEDWACS, adults enter seven pieces of information:<\/p>\n

Age, sex, body mass index, waist circumference, systolic blood pressure, upper arm circumference, and thigh length.<\/p>\n

The measurements can be collected at home with a tape measure, bathroom scale, and standard blood pressure monitor. The researchers selected these seven factors from nearly 3,700 candidates analyzed by a machine learning system.<\/p>\n

Testing the Diabetes Risk Model<\/p>\n

The model was developed using 30 years of data from the National Health and Nutrition Examination Survey, a major US health research program. It included adults of both sexes beginning at age 18.<\/p>\n

The team then evaluated the model using separate datasets from the United States and South Korea. Because researchers already knew which participants had prediabetes or diabetes, they could compare the tool\u2019s predictions with confirmed health outcomes.<\/p>\n

In both external validations, MEDWACS performed as well as or better than other established risk assessment methods, according to the study. The researchers concluded that it could offer an accessible way to identify people who should seek clinical testing.<\/p>\n

Why Thigh Length May Predict Diabetes Risk<\/p>\n

Among the seven factors, thigh length is easily the most unexpected. Even the researchers were initially surprised that it carried useful information.<\/p>\n

Maggiore said the measurement may capture two different influences on diabetes risk: childhood development and adult muscle mass.<\/p>\n

\u201cThe length of the femur bears witness to nutrition in early childhood. Poor nutrition in the first years of life slightly inhibits bone growth and is closely linked to an increased risk of diabetes decades later. Furthermore, the body\u2019s largest muscle group is also located in the thighs, and these muscles are responsible for removing sugar from the blood. Overall, shorter legs mean that a person has less muscle mass to absorb that sugar, which increases the risk of diabetes.\u201d<\/p>\n

Skeletal muscle removes much of the glucose circulating in the bloodstream by taking it in for energy or storage. Having less muscle mass may therefore reduce the body\u2019s ability to clear glucose.<\/p>\n
