Quality of life in treated hypertension: A case-control community based study

The aim of this case-control community study was to determine whether there was a difference in quality of life between hypertensive subjects and matched normotensive controls. Cases aged 40-79 years were randomly selected from a hypertensive register and matched with controls for age, sex, ethnicity and health centre. Cases had phase V diastolic blood pressure (DBP) greater than or equal to 100 mmHg or systolic blood pressure (SEP) greater than or equal to 180 mm Hg, or were on anti-hypertensive medication. Controls had DBP less than or equal to 90 mm Hg and no record of raised BP or anti-hypertensive treatment within the past year. Quality of life was measured by self-administered questionnaire. Data from 90 matched pairs, average age 62 years, with 47% men, were analysed; 80 hypertensive subjects were on anti-hypertensive medication. Hypertensive subjects showed an impairment in well-being compared with controls. They had a lower Health Status Index, had more sickness absence from work, greater symptomatic complaint and impaired psychological well-being. Relatives also reported a poorer quality of life in the hypertensive subjects. This impairment could be a result of the disease, adverse effects of drug treatment or to the effects of labelling.
