Sit-up test for assessing impaired blood pressure regulation in community-dwelling older adults: a cross-sectional study

Community-dwelling older adults with orthostatic hypotension were characterized by an impaired increase in diastolic blood pressure during sitting up and high supine systolic blood pressure. Orthostatic hypotension was associated with adverse health outcomes, independent of supine and seated hypertension. These findings provide valuable insights for the application of the sit-up test in preventive health screenings for older adults.
