A Score Revealed a Sixfold Difference in Diabetes Risk

A study involving more than 206,000 adults in China tested whether three common health measurements could help describe the chance of developing type 2 diabetes. None of the participants had diabetes when the research began. From 2010 through 2016, they received recurring checkups that included body measurements and blood testing. New cases were identified through later blood sugar results or a diagnosis from a doctor.

Researchers calculated the triglyceride-cholesterol-body weight index, or TCBI, by multiplying triglycerides, total cholesterol, and body weight, then dividing by 1,000. Participants at the top end of the score range had over six times the diabetes risk of those at the bottom. The relationship persisted after the team adjusted for age, family history, smoking status, blood pressure, and other factors.

Risk climbed with the score, though the pace changed around 923. Below that point, the rise was sharper; above it, the increase became slower. The number is therefore a turning point in the pattern, rather than a boundary separating healthy from unhealthy results. The connection was more pronounced among women and people under 65 than among men and older participants.

For adults monitoring their metabolic health, the findings show how blood fats, cholesterol, and weight may offer a broader picture when considered together. However, researchers have not established whether TCBI performs similarly in other populations or improves on existing measurements. Because the participants attended routine screenings in China, further research is required before TCBI can assess a person’s individual risk. Routine health screenings remain the more dependable monitoring approach.
