Researchers looked at whether a simple measurement from a routine blood test—the creatinine-to-body weight ratio—might be linked to developing prediabetes. They studied health check-up data from over 173,000 adults across 11 Chinese cities, following them for a median of three years. Prediabetes means blood sugar levels are higher than normal but not yet high enough for a type 2 diabetes diagnosis.
During the follow-up, about 10.7% of participants (18,506 people) developed prediabetes. The analysis showed that people with a lower creatinine-to-weight ratio had a higher risk of developing prediabetes. The link appeared stronger in certain groups, including women, people aged 30–40, and those with normal blood pressure.
This was an observational study, which means it can only show an association, not prove that a low ratio causes prediabetes. The study did not report on safety concerns, as it analyzed existing health data rather than testing a treatment. The findings are a first step and need confirmation in other populations and study types. For now, this research suggests a potential new area for investigation in diabetes prevention, but the ratio is not yet a tool for individual risk assessment.
