    Article - En anglais


    To study the prevalence, awareness, treatment and control of arterial hypertension in the elderly population in Belgium.

    Study group 

    An age-and sex-stratified sample of 2212 Belgian subjects aged 65 years or more, selected from the original cohort of the Belgian Interuniversity Research on Nutrition and Health (BIRNH) study ; participation in this follow-up study was 72.6%. Methods : Blood pressure (BP) was measured at home by trained technicians using a standard protocol.

    Isolated systolic hypertension (ISH) was defined as a systolic BP >=160 mm Hg and a diastolic BP<95 mm Hg.

    Diastolic hypertension was defined as a diastolic BP >=95 mm Hg.

    The total hypertensive population was defined as all those with ISH, diastolic hypertension and with BPs<160-95 mm Hg but currently taking anti-hypertensive drugs.

    Awareness and treatment status were investigated through a structured interview.


    The prevalence of arterial hypertension was 43.9%, higher in women than in men and increasing with age in women ; elevated BP was found in 22.3 to 28.6% of the participants varying by age and sex.

    In the>75-year-old subjects this elevation was in two-thirds of the cases due to ISH ; 84% of all female hypertensives were aware of the condition compared to 68% in men.

    Treatment advice had been given in a majority of the aware subjects and two-thirds of all treated persons was under control. (...)
