Ambulatory Blood Pressure Monitoring in Hypertension
The primary objective of this proposal is to demonstrate that ABPM can be used to improve study design for interventional trials in children with hypertension.
|Study Design:||Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single Blind
Primary Purpose: Diagnostic
|Official Title:||The Role of Ambulatory Blood Pressure Monitoring (ABPM) in Interventional Trials Conducted in Children With Hypertension|
- The primary outcome measure is ABPM to examine borderline high blood pressure, mild or untreated blood pressure in children captured within a 24 hour period on two occasions within a week.
|Study Start Date:||July 2003|
|Study Completion Date:||March 2009|
|Primary Completion Date:||March 2009 (Final data collection date for primary outcome measure)|
ABPM is a standard technique in adult antihypertensive trials to study the magnitude and duration of effect of investigational drugs. These methods are needed for pediatric studies. Before such methods can be developed, preliminary information must be collected to demonstrate that the device can be used for antihypertensive studies in children (i.e, to determine the dropout rate following the first ABP study, to determine the frequency of white coat hypertension in a selected population, to compare casual (office) blood pressures commonly used to diagnose hypertension in children with those obtained by ABPM, and to assess the placebo effect in children with borderline and mild hypertension).
All participants will be asked to complete 24 hour ABPM on two occasions within one week. During the ABPM parents and children will be asked to keep a diary recording the times that the child slept. A crossover design will be used, where subjects are initially randomized to either drug or placebo and then will be crossed over to the other intervention at a set time during the study.
