Prevalence of metabolic syndrome in metallurgical workers from different shifts

Abstract

Objective: To investigate the prevalence of metabolic syndrome in workers from different shifts. Methods: The population consisted of 93 workers, divided into: first shift (6:00 AM to 2:00 PM), second shift (2:00 PM to 10:00 PM), third shift (10:00 PM to 6:00 AM) and productive shift in administrative hours (7:30 AM to 5:00 PM). The components of the metabolic syndrome were obtained by blood collection in a 12 hour fasting and anthropometric measurements, through the NCEP-ATP III criteria. Results: Seventy two percent were male, aged between 33 and 38 years. Metabolic syndrome was diagnosed in 26.8% of the sample. The highest prevalence occurred among first shift workers (p<0.000). The HDL-cholesterol, fasting glucose and triglycerides changes were higher in the first shift. There was difference in body weight, body mass index and chronotype (p=0.000), among working shifts. Conclusion: The prevalence of metabolic syndrome was higher among first shift workers.
