Abstract

Objective We assessed the cross-sectional association between sleep duration and untreated diabetes in Japanese men.Methods Participants included 20,744 men aged 30-64 years who first visited the general hospital in Tokyo for routine health assessments during 2003-2007. Untreated diabetes was defined as not being under diabetes treatment and fasting blood glucose of ≥126 mg/dL or hemoglobin A(1c) of ≥6.5%. Sleep duration (≤5, 6, 7, or ≥8 h) and confounders were assessed using a questionnaire. Logistic regression was used to calculate odds ratios (ORs) for diabetes after adjustment for confounders.Results The prevalence of untreated diabetes was 3.4% in all men. The prevalence of untreated diabetes by sleep duration was as follows: ≤5 h: 3.5%; 6 h: 3.3%; 7 h: 3.2%; and ≥8 h: 5.1%. Men who reported sleeping for ≤5 h (OR: 1.52, 95% confidential interval [CI]: 1.22-1.90) and ≥8 h (OR: 1.39, 95% CI: 1.05-1.85) were significantly more likely to have untreated diabetes compared with those who reported sleeping for 7 h. In stratified analyses by obesity (body mass index ≥25.0 kg/m(2)), the association between long sleep duration (≥8 h) and untreated diabetes remained significant only in obese men.Conclusion Short sleep duration was significantly associated with untreated diabetes in both nonobese and obese men. Regarding long sleep duration, a significant association was observed in obese men only.

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.
