Abstract

OBJECTIVE: to determine the prevalence of orthostatic hypotension (OH) and associations with medication use in community-dwelling older women. DESIGN: cross-sectional analysis using data from the British Women's Heart and Health Study. SETTING: general practices in 23 towns in the UK. PARTICIPANTS: 3,775 women aged 60-80 years from 1999 to 2001. MAIN OUTCOME MEASURE: orthostatic hypotension-drop of > or =20 mmHg in systolic and/or a drop of > or =10 mmHg in diastolic blood pressure on standing. RESULTS: prevalence of OH was 28% (95% confidence interval [CI] 26.6, 29.4), which increased with age and hypertension. Regardless of treatment status or diagnosed hypertension, raised blood pressure was strongly associated with OH (P < 0.001). OH was strongly associated with number of antihypertensives taken (none vs three or more: odds ratio [OR] 2.24, 95% CI 1.47-3.40, P < 0.001); the association was slightly attenuated after allowing for age and co-morbidities (OR 1.99; 95% CI 1.30, 3.05; P = 0.003). Women with multiple co-morbidities had markedly increased odds of OH independent of age, number and type of medications taken (none vs four or more diagnoses: OR 2.28, 95% CI 1.58-3.30, P = 0.005). CONCLUSION: uncontrolled hypertension, use of three or more antihypertensives and multiple co-morbidities are predictors of OH in older women. Detection or monitoring of OH in these groups may prevent women from suffering its adverse consequences.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The total number of BP-lowering medications or the use of three or more antihypertensive drugs may be a significant predictor of OH.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
