title: [The influence of the work shift in patients with type 2 diabetes].
abstract: OBJECTIVE
  This study aimed to investigate the relationship between the work shift and diabetic patients.
  
  
  METHODS
  A cross-section study was performed in a cohort of 95 type 2 diabetic patients that work in the Hospital de Clinicas de Porto Alegre. Patients were divided into 2 groups according to the shift, day or night work. Patients underwent clinical and laboratory evaluations.
  
  
  RESULTS
  There were no significant differences in age, gender, diabetes duration, body mass index, blood pressure, fasting glucose, A1c (1%), triglycerides, total cholesterol, LDL cholesterol, HDL cholesterol, serum creatinine and uric acid. A higher average of waist circumference was found in the group of night workers.
  
  
  CONCLUSIONS
  Waist circumference was greater in the group of night workers; which may be indicative of insulin resistance in this group of patients. Our research indicates that the shift is not associated with a worsening of metabolic control in subjects or presence of diabetic nephropathy.
