Hypertension and combinations of cardiovascular risk factors. An epidemiologic case-control study in an adult population in Guadeloupe (FWI).
Our aim was to quantify the association between hypertension and four well-known cardiovascular risk factors (obesity, dyslipidemia, high blood glucose, smoking) and to determine the extent of their combinations in hypertensive subjects in an adult population in Guadeloupe (FWI). A case-control study was conducted in 1999. Odds ratios (ORs) and 95% confidence interval (95% CI) of hypertension according to cardiovascular risk factors were calculated by a logistic regression model. In all, 4210 subjects were included in the study: 2105 hypertensives and 2105 age and sex matched non-hypertensive controls. In the hypertensives, obesity (30%) was the most frequent risk factor followed by dyslipidemia (23.2%), current smoking (11.5%) and high blood glucose (8.2%). But, prevalence of current smokers was higher in normotensives (13.9 vs. 11.5%, p < 0.01). Among cases, 44.5% had no risk factor other than hypertension. The proportion of subjects with multiple risks factors (< or = 2) was higher in hypertensives than in controls (55.5 vs. 6.5%,p < 0.001) and higher in women than in men in cases (58.1 vs. 51.8%, p = 0.005). The adjusted ORs (95% CI) of hypertension were 2.41 (2.02-2.88) for obesity, 1.39 (1.16-1.66) for dyslipidemia and 1.67 (1.20-2.32) for high blood glucose. Our study documents the high prevalence of combinations of cardiovascular risk factors in hypertensive subjects in Guadeloupe and confirms the need of a global risk approach in prevention and treatment of hypertension.
