Background: Recent studies reported high body mass index values in paramedic, with a high percentage of workers being considered overweight or obese. However, little evidence exists regarding which factors explained weight gain over time in paramedics. Objective: This study evaluated whether occupational stress, tobacco consumption, sleeping problems or emotional food disinhibition were associated with weight gain over time in paramedics compared to a control group. Method: A retrospective study was performed. The study consisted in a self-report questionnaire composed of 84 questions related to sleeping problems, emotional food disinhibition, tobacco consumption and occupational stress. Occupational stress was evaluated through lack of social support and effort-reward imbalance. A repeated measures regression model was used to explore relationships between body mass index (BMI) and characteristics related to employment. Results: Questionnaires from 283 controls and 295 paramedics were analyzed. Paramedics, but not controls, gained BMI over the period of employment, as shown by a significant interaction between Time and Occupation (F(2, 568)=6.28; p=.002). Men were more likely to gain BMI over the period of employment (F(1,568)=42.95; p<. 0001). Among all covariates tested, tobacco consumption (F(1,568)=5.68; p=.02), supervisor support (F(1,568)=5.25; p=.02) and emotional disinhibition of eating (F(3,568)=7.51; p<.0001) had a significant effect on BMI for both groups. Conclusion: Paramedics experienced a greater increase in BMI over their years of employment than controls, often leading to obesity. These findings suggest that both work environment and organizational factors influence weight gain among paramedics and other workers.
