Title Combined impact of health risk factors on mortality of a petroleum industry population
Bibliographic information Aug. 2009, Vol.51, No.8, p.916-921. 36 ref.
Abstract The objective of this study was to assess the combined impact of health risk factors on the mortality among employees of a large petroleum enterprise in the United States. A 21-year mortality follow-up of 12,896 employees was conducted. Hazard ratios in relation to several important risk factors were calculated using a Cox proportional hazards model. Employees with health risk factors had higher mortality rates for all-causes combined and for cardiovascular diseases compared to employees without such risk factors. Smoking, obesity, hypercholesterolemia, and hyperglycemia independently and significantly predicted cardiovascular disease mortality. Mortality risks from all causes and from cardiovascular disease increased with the number of risk factors present.
