Abstract

OBJECTIVE: To evaluate the association of fasting insulin level to incident dementia in a cohort of elderly men. METHODS: Data are from the Honolulu-Asia Aging Study, a community-based study of Japanese-American men, aged 71 to 91 years in 1991. Serum insulin was measured in 1991 and participants were grouped based on their insulin levels. Dementia was ascertained in 1991, 1994, and 1996 according to international guidelines. The 2,568 men dementia-free in 1991 were reexamined in 1994 and 1996; 244 new cases of dementia were diagnosed. Survival analysis with age as the time scale was used to estimate the risk (hazard ratio [HR] and 95% CI) for incident dementia associated with levels of insulin. RESULTS: The risk of dementia was increased at the two extremes of the insulin distribution (lower and upper 15th percentiles). Compared to the rest of the cohort subjects in the lowest 15th percentile and highest 15th percentile had an increased risk for dementia (HR = 1.54, CI 1.11 to 2.11 and HR = 1.54, CI 1.05 to 2.26). In men with insulin levels <22.2 mIU/L the risk for dementia decreased with increased levels of insulin (HR = 0.76, CI 0.72 to 0.79 for each increase of one logarithmic unit -2.72 mIU/L of insulin). In men with insulin levels >/=22.2 mIU/L the risk for dementia increased with increasing levels of insulin (HR = 1.64, CI = 1.07 to 2.52 for each 2.72 mIU/L). CONCLUSIONS: Both low and high levels of insulin are associated with an increased risk of developing dementia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
