A new study suggests that the length of a person's thighs could be an indicator of their risk for developing type 2 diabetes. Researchers from the Technical University of Denmark have developed an online test, named MEDWACS, which utilizes seven different parameters, including thigh length, along with basic demographic information, to assess diabetes risk.
The test was developed using 30 years of health data from the U.S. National Health and Nutrition Examination Survey. Testing conducted on groups in the United States and South Korea indicated that the exam was effective in identifying individuals with prediabetes and undiagnosed type 2 diabetes.
According to the study authors, short thigh length may be a surprising sign of increased diabetes risk. They suggest that the length of the femur, or thigh bone, reflects nutrition during early childhood. Poor nutrition in the initial years of life can slightly inhibit bone growth, which has been linked to a higher risk of developing diabetes later in life. Additionally, the thigh contains the body's largest muscle group, which plays a role in absorbing sugar from the blood. Shorter legs may indicate less muscle mass, leading to reduced sugar absorption and an increased diabetes risk.
Type 2 diabetes affects more than four million people in the UK, with an estimated 1.3 million more living with the condition undiagnosed. Symptoms such as fatigue, thirst, and increased urination can develop slowly and may go unnoticed for years. The MEDWACS test is designed to encourage individuals who might not suspect they have diabetes to seek medical attention, as a diagnosis typically requires a blood test.
Participants can perform the at-home test using common household items such as a tape measure, bathroom scale, and a standard blood pressure monitor to gather the necessary information. The test aims to provide a simple, accessible method for early detection and risk assessment.
