Orthostatic hypotension and health-related quality of life among community-living older people in Korea

Purpose: To investigate the association of orthostatic hypotension (OH) with health-related quality of life (HRQoL) in older people living in the community.

Methods: A cross-sectional design was used. A total of 217 participants aged 65 and older were classified as having OH if their systolic or diastolic blood pressure showed a drop of ≥ 20 mmHg systolic blood pressure or ≥ 10 mmHg diastolic blood pressure, respectively, within 3 min of standing. Participants provided demographic and medical information and responded to questionnaires about their HRQoL (EuroQoL-5D-3L), as well as depression, anxiety, cognitive function, and recent physical activities.

Results: The number of participants with OH was 117, and those without OH numbered 100. The mean HRQoL levels were 0.56 (SD 0.29) in the OH group and 0.74 (SD 0.25) in the non-OH group (p < .001). Participants with OH were more likely to be older, women, and smokers. These participants had fewer years of education, a greater history of stroke and hypertension, and a greater number of comorbidities. The absence of OH, a higher physical activity level, a lower degree of depression, an absence of stroke history, and younger age were all significant determinants of greater HRQoL.

Conclusions: The level of HRQoL of older people with OH was significantly lower than that of older people without. The presence of OH was an independent determinant of HRQoL in older adults after adjusting for covariates. This finding suggests that strategies for relieving OH could improve HRQoL in affected older adults.
