Prehypertension Labeling (Tanya K23)

This study has been terminated.
(PI left institution)
Information provided by (Responsible Party):
Columbia University Identifier:
First received: September 8, 2011
Last updated: July 13, 2017
Last verified: July 2017
The purpose of this study is to find out whether labeling adults with prehypertension has negative effects on clinic blood pressure and quality of life 3 months after diagnosis.

Condition Intervention
Prehypertension Behavioral: Labeled prehypertension Behavioral: Unlabeled prehypertension

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Screening
Official Title: Diagnostic Labeling: Effect on White Coat Hypertension

Further study details as provided by Columbia University:

Primary Outcome Measures:
  • Change in blood pressure [ Time Frame: Baseline, 3 months ]

Secondary Outcome Measures:
  • Change in health-related quality of life (SF-12 questionnaires) [ Time Frame: Baseline, 3 months ]

Enrollment: 100
Actual Study Start Date: July 13, 2009
Study Completion Date: July 9, 2012
Primary Completion Date: July 9, 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Labeled Behavioral: Labeled prehypertension
A study physician informs subjects of their blood pressure level. Subjects are told they have prehypertension and are informed of the associated health risks.
Active Comparator: Unlabeled Behavioral: Unlabeled prehypertension
A study physician informs subjects of their blood pressure level. The term "prehypertension" is not used and associated health risks are not discussed.

Detailed Description:
Previous research has shown that a diagnosis of hypertension is associated with subsequent increases in resting blood pressure, and there is preliminary evidence of a cross-sectional association between hypertension labeling and the white coat effect. The white coat effect may be particularly problematic in prehypertensives, because a small elevation in clinic blood pressure could result in crossing the diagnostic cutoff for hypertension, potentially leading to misdiagnosis and unnecessary treatment. This study will examine effects of prehypertension labeling on clinic and ambulatory blood pressure, and will examine potential psychological mediators of these associations.
