Overweight/obesity and physiological variables in workers exposed to rotating shift in a food production factory.

Introduction: Shift work has been hypothesized as a potential risk factor for overweight/obesity or other metabolic changes. We examined the relationship between work shift and body mass index, waist-hip ratio, lipid profile, and glucose concentration in workers from a food manufacturing factory in Colombia.

Objectives: To investigate the association between shift work and changes in physiological variables in food manufacturing industry workers in Medellín, Colombia.
