Methods: Cross-sectional study of 968 male career firefighters. Cardiorespiratory fitness was measured by maximal exercise tolerance tests. Cardiovascular disease risk parameters included body composition, resting vital signs, and metabolic profiles. Group comparisons were performed using chi(2) test, analysis of variance, and general linear regression with/without adjustment for age and body mass index (BMI). Results: Highermetabolic equivalents categories were significantly associated with lower diastolic blood pressure, body fat, triglycerides, low-density lipoprotein cholesterol and total/high-density cholesterol ratio, and higher high-density lipoprotein (P <= 0.0272, age and BMI adjusted). Conclusions: Increasing CRF has beneficial independent effects on CVD risk factor profiles among firefighters. Higher CRF was beneficial regardless of BMI, nevertheless, increasing BMI had strong independent unfavorable effects. Firefighters should be encouraged to increase their CRF to decrease their future risk of CVD.||Description:||The authors would like to thank all the participating firefighters and fire departments, the staff and clinical leadership of the clinics who examined the firefighters, and Ms Brianne Tuley, Dr Sara Jahnke, Dr Lilly Ramphal, and the late Dr William Patterson for their contributions to the underlying longitudinal study. The authors also thank Dr. Charles A. Czeisler, Dr. Steven W. Lockley, Mr. Jason Sullivan and the Harvard Work Hours Health and Safety Group for providing data on one of the fire departments. This investigation was supported by the Federal Emergency Management Agency (FEMA) Assistance to Firefighters Grant (AFG) program's awards EMW-2006-FP-01493 (PI: Dr S.N. Kales), EMW-2009-FP-00835 (PI: Dr S.N. Kales) and EMW-2007-FP-02197 (PI: Dr. C.A.
