| Summary: | ABSTRACT Objective: To investigate factors that are associated with type 2 diabetes Mellitus in shift workers of a slaughterhouse in Southern Brazil. Methods: This cross-sectional study included 1,194 18- to 50-year-old workers of both sexes. The presence of type 2 diabetes Mellitus was self-reported and confirmed by the use of hypoglycemic drugs or insulin. The independent variables were sex, age, skin color, marital status, education level, family income, leisure time physical activity, smoking, and self-reported health and nutritional status (body mass index and waist circumference). Multivariate analysis was performed from an a priori conceptual model. Results: The prevalence of diabetes was 1.3% (95%CI=0.6-1.9). Type 2 diabetes Mellitus was associated with poor or regular self-reported health (OR)=3.72; 95%CI=1.28-10.78) and level II abdominal obesity ³102 for men and ³88 for women (OR=5.76; 95%CI=1.07-29.10). Conclusion: The prevalence of type 2 diabetes Mellitus was low. Moreover, the study evidenced the importance of using waist circumference to surveil and screen for metabolic diseases, such as type 2 diabetes Mellitus, and to monitor the low quality of life in the study individuals given the poor self-perceived health of workers with the said disease.
