The Claim

Female night shift workers have lower HDL cholesterol levels than female day workers, while no significant difference in HDL cholesterol levels exists between male night shift workers and male day workers, indicating a sex-specific association between night shift work and lipid metabolism.

In plain English

Women who work nights might have lower levels of the 'good' cholesterol than women who work during the day, but this doesn’t seem to happen in men—so night shifts might affect women’s cholesterol differently.

Female night shift workers may have lower HDL cholesterol levels compared to female day workers, while no such difference is observed in men, suggesting a sex-specific association between night shift work and lipid metabolism.
