Clinical obesity genetic scores better predict cardiovascular risk
Clinical obesity genetic scores placed 34.6% of UK Biobank participants in different inherited obesity risk groups than genetic scores for body mass index.
Our read
Biomarkers- Studied:
- Cohort study of UK Biobank participants (Independent replication)
- What changed:
- Clinical obesity polygenic scores reclassified 34.6% of individuals, improving risk discrimination for myocardial infarction, heart failure, and stroke
- The catch:
- The analysis did not measure whether score-guided care prevented cardiovascular events

UK Biobank participants were studied in an observational analysis comparing genetic scores for clinical obesity and body mass index, a measure of weight relative to height. The scores combined information from 2.3 million genetic variants. Clinical obesity considers excess body fat and its dysfunction, rather than body size alone.
After accounting for both scores, researchers found that clinical obesity scores had stronger associations with blood pressure, blood sugar and blood fat levels. They also better distinguished the risk of heart attack, heart failure and stroke. Researchers validated the improvement in risk classification in four other prospective cohorts—studies that followed people over time.
Why it matters
For cardiovascular diseases that become more common with age, the work addresses whether genetic risk assessment benefits from looking beyond body size alone.
Caveats
The observational analysis assessed how the scores classified risk, not whether score-guided care prevented cardiovascular events. The findings were reported in a conference abstract.
