This study was designed to estimate the prevalence of hypertension in Guadeloupe, the French West Indies, and to evaluate the risk factors associated with hypertension in the largest ethnic group, that of African origin. Households were randomly selected using a two-stage systematic sample of districts and then of houses; all adults aged 18 years in the household were included. In total, 1043 men and women were studied. Blood pressure, plasma glucose concentrations and gamma-glutamyl transferase activity were measured, hypertensive treatment and lifestyle factors recorded. The prevalence of hypertension, age-standardized to the Guadeloupe population was 21% and 26% in men and women of African origin, 28% and 22% in those of Indian-origin and 18% and 16% for other origins. The vast majority of subjects were unaware of their hypertension (90% of men, 74% of women). After adjustment for age, factors associated with high blood pressure in the 826 adults of African origin were: obesity, hyperglycemia, low educational level and family history of hypertension and of stroke. Additional factors in women were alcohol consumption, gamma-glutamyl transferase activity, physical inactivity, occupational category and a retired status, even after adjustment for age. Measures must be taken to diagnose hypertension early, particularly in individuals of African and Indian origin. An effective education program is needed, with an emphasis on life-style factors associated with obesity: diet and physical activity. |
