Key result
Overweight (BMI 25-29.9) was associated with a reduced risk of aneurysmal subarachnoid hemorrhage (HR 0.7; 95% CI 0.4-1.0), whereas total cholesterol and triglycerides showed no overall association.
Why the study?
Are BMI and serum lipids associated with the risk of aneurysmal subarachnoid hemorrhage in a general population?
Cohort (n=92,408)
Yes
Are BMI and serum lipids associated with the risk of aneurysmal subarachnoid hemorrhage in a general population?
Hazard Ratio: 0.7 (95% CI 0.4–1)
Overweight may be associated with a reduced risk of aneurysmal subarachnoid hemorrhage, while serum lipids show no overall association.

Does not support practice change; leaves open causal BMI-lipid roles in aneurysmal subarachnoid hemorrhage risk.
Sandvei et al. (2011) conducted a cohort in Aneurysmal subarachnoid hemorrhage (aSAH) (n=92,408). Overweight (BMI 25-29.9) vs. Normal weight (implied reference) was evaluated on Aneurysmal subarachnoid hemorrhage (aSAH) (HR 0.7, 95% CI 0.4-1.0). Overweight (BMI 25-29.9) was associated with a reduced risk of aneurysmal subarachnoid hemorrhage (HR 0.7; 95% CI 0.4-1.0), whereas total cholesterol and triglycerides showed no overall association.
