Trends in hypertension prevalence, treatment, and control : In a well-defined older population.
Annual Fall Conference and Scientific Sessions of the American Heart Association Council for High Blood Pressure Research. Washington, DC, USA, 1997/09/16.
To assess medical attention focused on hypertension (HBP) in the elderly, this study examines trends in HBP prevalence, treatment, and control status in a defined population of persons =65 years of age enrolled in a large HMO.
Random samples of approximately 400 persons were drawn for the years 1967,1974,1981, and 1988.
First recorded ambulatory pressures, available on over 90% of subjects in each period, were obtained from medical records.
Prevalence of HBP (SBP= 160 and/or DBP=95, and/or taking anti-HBP drugs) ranged between 44% to 53%. Proportion with HBP on treatment increased from 25% in 1967 to 60% in 1988 (P<. 001) ; proportion on treatment and controlled (SBP<16 (), DBP<95) increased from 8% to 34% (P<. 001), Mean population SBP declined from 155.2 in 1967 to 144.0 in 1988 (P<. 001) ; mean DBP declined from 85.2 to 81.2 (P<. 001), Proportion with isolated systolic hypertension (ISH) (SBP=160, DBP<90) remained unchanged at 12% to 14%. Use of diuretics and adrenergic antagonist agents declined while use of beta blockers and newer classes of anti-HBP drugs increased significantly among treated hypertensives in the 1980s, These findings parallel HBP trends in younger adults from National Health Survey data though we find evidence ofa substantial gap in addressing the problem in the elderly, who constitute the population at greatest risk of cardiovascular complications of HBP.
