SANTANA-HERRERA, José; ALFANO, Tony  and  ESCOBAL-MACHADO, Adriana. Shift Work: a cardiovascular factor risk?. Med. segur. trab. [online]. 2014, vol.60, n.234, pp.179-197. ISSN 1989-7790.  https://dx.doi.org/10.4321/S0465-546X2014000100014.

Objective: The aims of this review are to identify the scientific evidence in the association between shift work and cardiovascular risk factor and identify what interventions are more effectives in the different type of shift works to reduce this risk. Methods: A literature search has been performed in 10 scientific databases, taking into account the level of evidence we select 13 articles. The design of this studies was: 7 of interventions, 1 of cohort, 1 of retrospective cohort, 3 transversals descriptive an 1 pilot study. These covered a diverse range of interventions: changes to the speed, direction, and use of rotation; ergonomics and changes in the numbers to shift work, analyzed the modification of biomarkers by type of intervention. Results: 12.332 workers were examined. The change in the direction of the shift work from backward to forward shift rotation showed positive changes such as decreased glucose, TG, Ac. Uric and TAS. Rapid clockwise rotation can be beneficial observed a reduced total cholesterol, cholesterol ratio Total/LDL and increase of the HDL. By associating the direction and speed of rotation no significant changes in biomarkers were obtained. The ergonomic change shifts decreased lipid abnormalities, TA and FC. Finally Diabetes Mellitus was negatively influenced when switching from three shifts to two shifts. Conclusions:The published articles suggest a negative impact of shift work on cardiovascular risk which can be modified favorably to changes in work organization (system fast clockwise rotation, flexible shifts and rotations of three shifts).
