Long-Term Longitudinal Study on the Relationship Between Alternating Shift Work and the Onset of Diabetes Mellitus in Male Japanese Workers
Abstract
OBJECTIVE: This study investigated the effect of alternating shift work (ASW) on the onset of diabetes mellitus in Japanese workers compared with onset in day-shift work (DSW). METHODS: A longitudinal study was carried out on a DSW group (n = 3203) and ASW group (n = 2426) of a steel company who received their annual health checkups over a 10-year period between 1991 and 2001. The association between job schedule type and onset of diabetes mellitus (glycated hemoglobin A1c > or =6.0% or medication) was investigated by multivariate pooled logistic regression analyses. RESULTS: The odds ratio (95% confidence interval) for the development of diabetes mellitus in the ASW group compared with the DSW group was 1.35 (1.05-1.75). CONCLUSIONS: Our study revealed that the ASW is an independent risk factor for the onset of diabetes mellitus.

The increased risk of diabetes and cardiovascular disease documented in epidemiologic studies of shift work is unlikely to be solely due to sleep loss and would not be fully mitigated by strategies designed to preserve sleep duration.
“The increased risk of diabetes and cardiovascular disease documented in epidemiologic studies of shift work (4–9) is thus unlikely to be solely due to sleep loss and would not be fully mitigated by strategies designed to preserve sleep duration.”

Shift work is associated with an increased risk of type 2 diabetes and cardiovascular disease.
“Prospective epidemiologic studies indicate that shift work is associated with an increased risk of type 2 diabetes and cardiovascular disease (4–9).”

Increased diabetes risk in shift workers may be amplified by unhealthy lifestyle changes such as smoking, alcohol consumption, and lack of exercise.
“The increased diabetes risk may be further amplified by unhealthy changes in lifestyle associated with shift work (e.g., smoking, alcohol consumption, and lack of exercise) [33].”

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.
