Greater body roundness index among diabetes patients associated with Increased stroke risk: Study

A new study published in the journal of Diabetes Research and Clinical Practice showed that higher stroke risk is associated with greater body roundness index (BRI), particularly in people with diabetes and prediabetes. In stroke prediction, BRI performed better than other adiposity markers, demonstrating its usefulness for risk stratification in people with glucose impairment.

Stroke is one of the leading causes of mortality and permanent disability globally, posing serious public health issues, especially for older adults. Developing successful preventive measures in clinical settings requires an accurate assessment of modifiable risk variables. The development of the BRI, a new metric intended to more precisely estimate body fat percentage and visceral adipose tissue, is the consequence of recent advancements in anthropometric measurement.

In Chinese populations, the body roundness index (BRI), a new anthropometric indicator of obesity, has not been well studied for stroke prediction across various glucose metabolism statuses (GMS). Thus, this study investigated the relationship between BRI and the risk of new-onset stroke in middle-aged Chinese individuals.

A total of 7,969 individuals from the China Health and Retirement Longitudinal Study (2011–2020) were examined. To investigate the relationship between BRI and stroke, this study used sensitivity analyses, limited cubic splines, propensity score matching, and Cox regression. The predictive ability of BRI was compared to various anthropometric indicators across GMS categories using receiver operating characteristic (ROC) analysis.
