Obesity and metabolic syndrome show opposite glaucoma links
Adults classified as obese had lower odds of glaucoma than adults who were not overweight, with an odds ratio of 0.79.
Our read
Populations- Studied:
- Cross-sectional study of 156,362 adults over 40, against adults who were not overweight
- What changed:
- Adults classified as obese had lower odds of glaucoma than non-overweight adults (odds ratio 0.79)
- The catch:
- Existing glaucoma could precede obesity or metabolic syndrome, reversing the apparent order
- In the record:
- The 804th paper on metabolic syndrome with results in people; 2,426 on record in all.
- Why it’s aging research:
- It bears on staying healthy in midlife and later life.

Among 156,362 adults over 40 in the National Institutes of Health’s All of Us research program, a cross-sectional observational analysis examined links between body size and glaucoma, a group of eye diseases that damage the optic nerve. It also examined metabolic syndrome, defined as at least three risk factors involving waist size, blood fats, blood pressure or blood sugar.
Adults classified as obese by body mass index, a weight-to-height measure, had lower odds of glaucoma than adults who were not overweight. The odds ratio was 0.79; a value of 1 would mean no difference. Adults with metabolic syndrome had higher odds than those without it, with an odds ratio of 1.35. Being overweight and having a larger waist were also linked to lower odds of glaucoma.
Why it matters
For glaucoma, an age-related eye disease, the findings suggest that body size and metabolic health deserve separate consideration.
Caveats
The analysis measured existing glaucoma, so it could not determine whether body size or metabolic syndrome preceded it. The findings concern adults over 40, not younger people.
