Introduction:

Overweight and Obesity are a major public health problem in México, where poor working conditions like long working hours, rotating shifts and moonlighting are frequent and have a negative impact on the nutritional status of the economically active population.

Objective:

To determine the association between work related factors and overweight and obesity in young workers.

Materials and Methods:

cross-sectional study, in working adults with 2 groups of 136 patients for each, group one with normal weight (BMI≤24.9) and group two with overweight/obesity (BMI≥25). The factors to study were working hours, work schedule, shift rotation, moonlighting and occupational stress. Binary logistic regression, odds ratio and confidence intervals were used to determine the association between overweight/obesity and the work-related factors.

Results:

It was identified significant association between Overweight/Obesity with Long Work Hours (RM=4.23), Rotating Shift Schedule (RM=5.21), Night Shift (RM=5.55) and Moderate to Severe Occupational Stress (RM=4.92). The regression model that explains the Overweight/Obesity includes Long Work Hours, Night Shift and Work-Related Stress (p=0.000).

Conclusions:

There is association between Overweight/Obesity with Long Work Hours, Rotating Shift Schedule, Night Shift and Moderate to Severe Work-Related Stress.
