Cardiovascular alterations and night shift work disorder in nurses: a systematic review.

Cardiovascular diseases (CVD) are among the top causes of morbidity and mortality among Mexican adults. Night shift work disorder (NSWD) has been reported as a possible risk factor for CVD. The objective of this review was to determine whether there is an association between CVD and NSWD in nurses. We performed a systematic review of these variables in PubMed. Of 68 original research articles addressing CVD and NSWD in nurses, four found an association between CVD and NSWD. A possible association between these variables was documented, supported by the alteration of wake/sleep circadian cycles and the work schedules that characterize nursing work. In conclusion, there is a possible mild association between CVD and NSWD, in nurses. Preventive and early diagnosis and treatment measures must be developed for nursing staff that works night shifts in hospitals to reduce CVD.
