Abstract

Background

Sedentary lifestyles have been associated with increased morbidity and mortality. Radiology as a profession may be sedentary compared to some clinical disciplines.

Aim

Our aim was to measure the occupation-related energy expenditure of a cohort of radiologists versus clinicians using a specialized pedometer.

Methods

25 radiologists and 25 clinicians (15 surgeons, 8 physicians and 2 emergency physicians) were measured. The amount of steps walked, stairs climbed and calories burned on a given day from 9 a.m. to 5 p.m. were compared between the groups.

Results

The difference in mean calorie usage per day was 320 greater, and steps walked per day 2,985 greater, in clinicians than in radiologists (p < 0.0001 for each).

Conclusion

Such a difference in calorie intake can have significant long-term health implications in terms of increased weight or BMI. Means of combating this deficit are discussed.
