Abstract

Introduction: Few longitudinal studies assessed whether sleep disturbances are associated with dementia risk. Methods: Sleep disturbances were assessed in three population‐based studies (H70 study and Kungsholmen Project [Sweden]; Cardiovascular Risk Factors, Aging and Dementia study [Finland]). Late‐life baseline analyses (3–10 years follow‐up) used all three studies (N = 1446). Baseline ages ≈ 70 years (Cardiovascular Risk Factors, Aging and Dementia, H70), and ≈84 years (Kungsholmen Project). Midlife baseline (age ≈ 50 years) analyses used Cardiovascular Risk Factors, Aging and Dementia (21 and 32 years follow‐up) (N = 1407). Results: Midlife insomnia (fully adjusted hazard ratio = 1.24, 95% confidence interval = 1.02–1.50) and late‐life terminal insomnia (fully adjusted odds ratio = 1.94, 95% confidence interval = 1.08–3.49) were associated with a higher dementia risk. Late‐life long sleep duration (>9 hours) was also associated with an increased dementia risk (adjusted odds ratio = 3.98, 95% confidence interval = 1.87–8.48). Discussion: Midlife insomnia and late‐life terminal insomnia or long sleep duration were associated with a higher late‐life dementia risk.

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.
