Medical program for shift workers—impacts on chronic disease and mortality outcomes
Open accessAbstract
OBJECTIVE: In 1983, global chemical company BASF SE implemented a supplemental health protection program to help its employees cope with the stressors associated with shift work. The program included comprehensive medical examinations and health promotion activities targeted at shift workers. METHODS: To assess the possible long-term health impacts of the program, cohorts of 14,128 male rotating shift and 17,218 male day wage employees were established via electronic job history searches. Health examination and mortality records were linked to job histories and studied over an 11-year period. RESULTS: Between 1996 and 2006, there were 414 and 463 deaths among rotating shift and day work employees, respectively. Mortality risks were marginally lower among shift working employees when taking age and job level into consideration, and remained so when cigarette smoking, alcohol intake, and existing chronic disease conditions were included as explanatory factors. The incidence of obesity, diabetes, and diseases of the circulatory and digestive system, as diagnosed or reported during health examinations, was higher among shift work employees, possibly as a consequence of enhanced medical surveillance or a direct effect of shift work. CONCLUSION: Incorporation of extensive occupational medical examinations, health seminars, and other intervention programs may help mitigate the long-term health consequences of shift work.

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).”
From Circadian Misalignment Augments Markers of Insulin Resistance and Inflammation, Independently of Sleep Loss (2014) · cites this paper as [5]
The Results (Table 4) report higher diabetes incidence among rotating-shift workers, but classify cases as diabetes mellitus (E10–E14), not specifically type 2 diabetes. They also report increased risks for hypertensive diseases and conductive heart disorders, while finding no clear increase in ischemic heart disease. The claim therefore generalizes beyond the cardiovascular outcomes this study supports. (LLM, conf=0.85)
Experimental — accuracy not yet measuredThe 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.

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.
