Cardiovascular risk estimated after 13 years of follow-up in a low-incidence Mediterranean region with high-prevalence of cardiovascular risk factors

Table 4 Population risk of ischemic heart disease attributable to the major risk factors in a cohort of adult population from Murcia (south-east Spain)

Risk factor	Prevalence of exposition among the population (%)^e	95% CI	Relative risk^f	95% CI	Population attributable risk (%)	95% CI
Hypercholesterolemia^a	27.5	25.3 - 29.7	2.02	1.13 - 3.62	21.9	2.1 - 41.7
Hypertriglyceridemia^b	16.5	14.6 - 18.5	1.85	1.06 - 3.25	12.4	0 - 25.6
Hypertension^c	22.2	20.3 - 24.1	3.21	1.61 - 6.42	32.9	10.7 - 55.1
Diabetes^d	6.2	4.9 - 7.6	1.68	0.86 - 3.29	4.0	0 - 10.5
Ever smoker	58.7	56.1 - 61.4	2.41	1.18 - 4.91	45.0	14.9 - 75.1

PAR: Population Attributable Risk.
^aDefined as total serum cholesterol ≥240 mg/dl, prior diagnosis of hypercholesterolemia or prescribed use of lipid-lowering medication.
^bDefined as serum triglyceride concentration ≥150 mg/dl.
^cDefined as systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, prior diagnosis of hypertension or use of anti-hypertensive medication.
^dDefined as a self-reported diagnosis of diabetes or prescription of insulin or oral anti-diabetic medication.
^ePrevalence in the population of Murcia (20-70 years) standardized to the 2001 census population of the region (data from the DINO Study, 2002).
^fRelative risk estimated as the hazard ratio of Cox models adjusted by all variables in the table, plus educational level, body mass index, and physical activity of moderate or high intensity, and stratified by sex and age.
