Heart disease is the primary cause of on-duty deaths in firefighters, but little is known about their
lipid profile. We evaluated the
lipid profile in relation to other
cardiovascular disease risk factors in 321 firefighters at a baseline examination. Prospective comparisons were performed for 285 firefighters, who were enrolled in a statewide medical surveillance program, and had complete follow-up data for 4 years. The average
cholesterol level in firefighters declined from 224 mg/dL at baseline (1996-1997) to 214 mg/dL at the follow-up examination (P < 0.0001). Conversely, both
obesity (body mass index > or = 30; 34% versus 40%, P = 0.008) and
triglycerides (> or = 200 mg/dL; 27% versus 35%, P = 0.047) increased over time. The proportion of firefighters taking
lipid-lowering medications increased from 3% at baseline to 12% at follow-up (P < 0.0001).
Cholesterol levels declined significantly, and treatment rates for
elevated cholesterol increased over time. Despite repeated examinations, a considerable number of firefighters had persistently
elevated cholesterol, and only a minority were receiving adequate treatment.
