Validation of Hand Held Indirect Calorimeter in Overweight and Obese Patients

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Milton S. Hershey Medical Center
ClinicalTrials.gov Identifier:
NCT00670969
First received: April 30, 2008
Last updated: June 16, 2017
Last verified: June 2017
  Purpose
The purpose of this study is to determine, in a group of overweight or obese volunteers, if a handheld indirect calorimeter can accurately measures oxygen consumption to determine resting metabolic rate compared to a portable indirect calorimeter.

Condition
Obesity

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Validation of Handheld Indirect Calorimeter in Overweight and Obese Patients

Further study details as provided by Milton S. Hershey Medical Center:

Primary Outcome Measures:
  • Validate handheld calorimeter against a portable device [ Time Frame: 1 hour ]

Enrollment: 101
Study Start Date: May 2008
Study Completion Date: February 10, 2014
Primary Completion Date: February 10, 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
A
People who will have the portable measurement taken first and handheld measurement taken second
B
People who will have the handheld measurement taken first and portable measurement taken second

Detailed Description:
  1. Background and Rationale: With the growing number of overweight and obese Americans, health professionals need accurate and convenient tools to help personalize weight loss programs. Portable indirect calorimetry measurements are more expensive than handheld devices and often limited to research setting only, making them impractical for clinical use. Additionally equations used to estimate resting metabolic rate may be significantly inaccurate in overweight patients. Several studies have been conducted to determine the accuracy of handheld devices, however none have been done in the overweight and obese populations. If handheld calorimeters can accurately measure resting metabolic rate in overweight and obese patients, these tests may be used to improve and personalize weight management programs.
  2. Key Objectives: To determine in a group of overweight or obese volunteers if a handheld indirect calorimeter can accurately measures oxygen consumption to determine resting metabolic rate.
