Prevalence, awareness, and control of hypertension in elderly and very elderly in Poland: results of a cross sectional representative survey
Objective: The aim of the study was to examine prevalence, awareness, and control of hypertension in elderly and very elderly in Poland. Methods: The random sample of 4950 study participants aged 65 or more (age range 65 104 years) equally distributed in six age subgroups, and participated in cross sectional, nationally representative survey PolSenior. During two separate visits, standardized interviews on awareness of hypertension as well as anthropometric measurements, blood pressure (BP) and heart rate readings were obtained. Hypertension was defined according to 2013 European Society of Hypertension/European Society of Cardiology Guidelines. Results: Mean SBP was highest in men aged 75 79 years (148.3 mmHg) and in women aged 80 84 years (149.9 mmHg) and then steadily decreased, whereas DBP decreased steadily from age 65. Hypertension affected about 80% of septuagenarians. Its prevalence decreased with age to 67% in women and 60% in men aged 90 years or older. In nonagenarians, awareness of hypertension (72% in women and 61% in men) and percentage of treated study participants (64% of women and 54% of men) was the lowest. In contrast, among treated study participants proportion of well controlled (BP 140/90 mmHg) was the highest in people older than 85 reaching 34% among nonagenarian women and 38% in men. Conclusions: The results show a reversed trend in prevalence and control of hypertension in people aged 80 years and older when compared with the younger elderly. As awareness and treatment of hypertension decreases with advanced age, it seems reasonable to extend screening programs and antihypertensive initiatives for the elderly and very elderly.
