Objectives: To study blood pressure distribution according to the new classification criteria of the JNC VI. To study the other cardiovascular risk factors related to blood pressure stage.
Method: A cross sectional survey was undertaken in a medical center in Guadeloupe in 1999. The study included 1016 consecutive adult subjects. Blood pressure measurements were done with an automated oscillometric method (dynamap).
Results: A total of 609 women and 407 men participated in the study. Hypertension (systolic blood pressure > or = 140 mmHg and/or diastolic blood pressure > or = 90 mmHg or being on antihypertensive medication) was present in 326 subjects (32.1%). Hypertension was more frequently found in men than in women (p = 0.008). Over the whole sample, 53.1% had optimal or normal blood pressure, 14.9% had high normal blood pressure, 16.1% were stage 1 hypertension and 15.9% were stage 2 or 3 hypertension or were on antihypertensive medication. Prevalence of hypercholesterolemia (total cholesterol > or = 240 mg/dl) increased significantly with increasing blood pressure in men (p = 0.002) and women (p < 0.001). Prevalence of dyslipidemia (total cholesterolemia > or = 240 mg/dl or HDL-cholesterol < 35 mg/dl or currently receiving antihyperlipidemic therapy) increased significantly with increasing blood pressure in both sex (p < 0.001). The same trend was found for prevalence of obesity (BMI (30 kg/m2) in both sex (p < 0.01).
Conclusion: In this population with a high prevalence of hypertension, we showed that hypercholesterolemia and obesity increased significantly with increasing blood pressure. We also showed that caring for high blood pressure should be part of a global caring of the patient looking for other cardiovascular risk factors.
