Wu QJ, Sun H, Wen ZY, et al. - This study’s findings demonstrate that shift work was correlated with several health outcomes with different levels of evidence. Highly suggestive evidence supports the relationships between myocardial infarction and diabetes mellitus incidence.

• Researchers distinguished eight eligible systematic reviews and meta-analyses, providing data on 16 associations.

• Highly suggestive evidence for relationships between shift work and myocardial infarction (having ever vs having never done shift work) and diabetes mellitus incidence (per five-year increment in shift work) was observed.

• There was a relationship between shift work and diabetes mellitus incidence (having ever vs having never done shift work).

• As per the findings, two health outcomes, including prostate cancer incidence (having ever vs having never done shift work and rotating night shift work vs daytime work), and colorectal cancer incidence (longest vs shortest shift work time) were only supported by weak evidence.
