Serum uric acid and hypertension: the Olivetti heart study.
The association between serum uric acid and hypertension was evaluated in a sample of male workers in southern Italy enrolled in the Olivetti Heart Study, an ongoing longitudinal epidemiological investigation on risk factors for coronary heart disease carried out at the Olivetti factory in the suburban area of Naples. Participants were screened at baseline (1975) and at five year (1980) and 12 year (1987) follow-up examinations. The present report focuses on 619 male workers for whom information on coronary heart disease risk factors was available both at baseline and 12 year follow-up examination. At baseline, after excluding hypertensive participants (systolic blood pressure (SBP) > or = 140 mmHg and/or diastolic blood pressure (DBP), > or = 90 mmHg and/or on antihypertensive therapy; n = 72), serum uric acid was positively and significantly related to age, SBP, DBP, body mass index (BMI), serum total cholesterol (CHOL) and serum triglycerides (TG) in 547 normotensive participants. At 12 year follow-up examination, hypertension was defined by SBP > or = 140 mmHg and/or DBP > or = 90 mmHg and/or being on antihypertensive therapy. Multiple logistic regression analysis showed an independent positive association between serum uric acid levels and development of hypertension (RR = 1.23, 95% CI = 1.07-1.39; p = 0.011) after adjustment for age, BMI, CHOL and TG. Furthermore, according to more severe degrees of hypertension (SBP > or = 160 mmHg and/or DBP > or = 95 mmHg and/or being on antihypertensive therapy), the relative risk to develop hypertension was still significant (RR = 1.19; CI = 1.01-1.38; p = 0.051).(ABSTRACT TRUNCATED AT 250 WORDS)
