Firefighters and on-duty deaths from coronary heart disease: a case control study

Table 5 Multivariable-adjusted odds ratios for the association of risk factors and on-duty CHD^† death.

	OR^@ (95% CI^$)*
	Model 1 Age < 60^§	Model 2 Age <60 and no prior CHD diagnosis^‡‡
Age ≥ 45 years old	6.5 (2.6 – 15.9)	6.2 (2.4 – 16.0)
Current Smoking	7.0 (2.8 – 17.4)	8.7 (3.3 – 22.5)
Hypertension	4.7 (2.0 – 11.1)	6.2 (2.4 – 15.7)
Diabetes Mellitus	2.0 (0.5 – 8.6)	2.4 (0.5 – 13.1)
Prior Diagnosis of CHD or other evidence of arterial-occlusive disease	15.6 (3.5 – 68.6)	-

* Odds ratios are adjusted for all other risk factors in the table. For example, the OR for current smoking is adjusted for age ≥ 45 years old, hypertension, diabetes and prior CHD. ^§ Model 1 included all CHD death cases (n = 46) and active control firefighters (n = 308) less than 60 years old. ^‡‡ Model 2 was restricted to firefighters less than 60 years of age without a prior diagnosis of CHD or other evidence of vaso-occlusive disease. Cases (n = 33) and controls (n = 305). ^†See Table 1; ^@$See Table 2.
