Abstract

High prevalence and poor control of hypertension have been observed in populations with low-socioeconomic status. Comparing an unemployed population with another employed population sharing the same culture, and another employed population living in another environment might enlighten the effects of factors accessible to primary prevention on the one hand and access to health care on the other hand. The objectives are, first, to describe blood pressure (BP) prevalence and control in an unemployed Caribbean population benefiting from State financial support and good access to health care and second, compare the results in this population with those observed, with the same methodology in two employed populations, one in the Caribbean and one in metropolitan France. A cross-sectional study of 2420 consecutive unemployed subjects referred for check-up in the two health centres of Guadeloupe, a French Caribbean island. Hypertension prevalence was 25.2% in men and 22.1% in women. BP was controlled in 17.3% of men and 37.2% of women receiving antihypertensive medication. Among women, 58% were overweight and 29% obese. Prevalence of hypertension was higher among the unemployed and employed Caribbean population, than among an employed metropolitan French population. A high prevalence of obesity was observed in the two Caribbean populations suggesting the interest of primary prevention in the Caribbean. Burden of hypertension in a population relates to the development of hypertension (primary prevention) and control of hypertension (secondary prevention). Identifying hypertensive patients and controlling blood pressure are both important to reduce the disease burden.
