Objective: The aim of this study was to determine the role of obesity on the association between sleep and on-duty injury among male career firefighters.

Methods: Data on 1419 male career firefighters for this cross-sectional study came from two firefighter cohorts from 2008 to 2013. On-duty injury within the past 6 to 12 months was the dependent variable and getting enough sleep was the independent variable. A multivariable, mixed effect logistic regression model stratified by body mass index (BMI) categories was created to examine the presence of effect measure modification.

Results: Only obese firefighters who did not get enough sleep were twice as likely to have an on-duty injury than those who got enough sleep. This association was not significant among normal or overweight firefighters.

Conclusions: Future studies into on-duty injury and sleep should examine body composition as an effect modifier among career firefighters.

Clinical Significance: Health care professionals should discuss weight management and sleep habits with male career firefighters to improve personal health and occupational health and safety, particularly on-duty injury.
