The WHEEL pilot study is a 12 week weight loss intervention in long-haul commercial truck drivers. The study involves two visits to the University of Utah's Rocky Mountain Center for Occupational and Environmental Health, one at the start of the study and a second one at the end of the study. Both visits include a general health history questionnaire, a 24-hour diet recall questionnaire, anthropometric measurements, as well as an assessment of blood pressure, hemoglobin A1c, and a cholesterol and lipid panel. Each truck driver is assigned a health coach who helps the driver create and achieve three health goals.
