[Knowledge and treatment of hypertension in La Plata, Argentina].

: Hypertensive subjects, aged 15-75 years, detected by the survey of Prevalence of Hypertension in La Plata, were evaluated to settle the rates of awareness, treatment, control status and the efficacy of pharmacologic therapy (EPT). The survey was composed of 2,090 subjects when the threshold of hypertension was equal to blood pressure (BP) greater than or equal to 140-90 mm Hg and of 1,203 subjects with a BP threshold greater than or equal to 160-95 mm Hg (Table I). The rates of awareness, treatment and control for the 140-90 mm Hg threshold were 43.97%, 33.06%, 4.9%, respectively, and the EPT was 15.03%. For the 160-95 mm Hg threshold the rates were 69.41%, 54.44% and 27.76% and the EPT was 48.32% (Table 2 and Fig. 1). The awareness and treatment rates for women were greater than those for men (p less than 0.0005) (Table 2). The EPT was similar in both sexes when the 140-90 mm Hg threshold was used while it was greater in women than in men with the 160-95 threshold (p less than 0.014) (Table 2). The rates of awareness and treatment increased with age and with the severity of the disease (Table 3-5). The EPT decreased from 85.71% in the 15-24 yr. age group to 10.56% in the 65-75 yr. age group (Table 4). Although the rates of awareness and treatment of hypertension found in La Plata were similar to those found in USA, the control of the disease was lower.(ABSTRACT TRUNCATED AT 250 WORDS)
