The effects of night work or shift work on workers' health are unknown, recent findings have indicated that may affect glucose tolerance, lead to obesity, diabetes and metabolic syndrome (MS). The desynchronization of the circadian cycle has been related to some of these effects, as well as sleep deprivation and exposure to light at night.
To study the association between shift work and chronic diseases and quality of life among health professionals of a university hospital and compare workers day and night shifts in relation to metabolic changes and altered sleep pattern.
Cross-sectional study conducted between April 2013 and December 2014. Sociodemographic data were evaluated and for the quality of life we used the WHOQOL BREF. Cronotypes and daily preferences sleep were investigated by Chronotype Questionnaire Munich (MCTQ ). Sleep quality was assessed by questionnaire Pittisburgh Sleep Quality Index. Physical examination was performed and venous blood was collected in fasting for 12 h for laboratory analysis.
The reduction of h slept or desynchronization of sleep (night work) can be a possible mechanism in the pathogenesis of obesity and should be better understood.
