title: Serum cholesterol and hemorrhagic stroke in the Honolulu Heart Program.
abstract: During an average 18 years of follow-up for 7,850 Japanese-American men in Hawaii who were free of stroke at entry, 116 developed hemorrhagic stroke (subarachnoid hemorrhage or intracerebral hemorrhage). There was a significant (p = 0.001) inverse association between serum cholesterol and the risk of intracerebral hemorrhage but not of subarachnoid hemorrhage. This inverse association was nonlinear, with a higher incidence rate only for men with serum cholesterol in the lowest quintile (less than 189 mg/dl). The relative risk (lowest quintile/other four quintiles) was 2.55 (95% confidence interval 1.58-4.12) after controlling for age, blood pressure, serum uric acid, cigarette smoking, and alcohol consumption. There was no evidence for an interaction between blood pressure and serum cholesterol, although the inverse association was stronger for normotensive than for hypertensive men. Public health implications would differ in different countries depending on the relative frequency of intracerebral hemorrhage and on the distribution of serum cholesterol levels in the population.
