A Comparison of Computer Vision Based Approach vs. Dual Energy X-ray Absorptiometry Scan to Measure Body Fat Percentage

Terminated

• Conditions: Health Behavior
• Interventions: Diagnostic Test: Computer based vision application by video; Radiation: whole body dual energy x-ray absorptiometry scan

• Registration Number: NCT04563637
• Lead Sponsor: Centennial Medical Group

Brief Summary

This study is being done to test whether a HealthReel computer vision-based software application can estimate body fat percentage with equivalent accuracy to a whole body dual energy x-ray absorptiometry scan.

Detailed Description

This study is being done to test whether a computer vision-based software application can estimate body fat percentage with equivalent accuracy to a whole body dual energy x-ray absorptiometry scan. The dual energy x-ray absorptiometry scan involves lying on a machine for about 6-10 minutes. It is an open design. The study will also examine whether waist circumference measurement improves the accuracy of the body fat percentage estimate by the computer vision-based application.A total of approximately 492 subjects are planned to take part in this study at one study center.

Arm && Interventions

Group	Intervention	Description
Computer Based Vision	Computer based vision application by video	A 15 second long video will be obtained at the research site using a smart phone or tablet. Then subjects will undergo a whole body dual energy x-ray absorptiometry scan . Then the subject will go home and take a second 15 second long video. The videos will then be analyzed by computer based vision application and the body fat percentage measured by dual energy x-ray absorptiometry scan will be compared.

Primary Outcome Measures

Name	Time	Method
variance in body fat percentage between computervision application and dexa scan	8 months	Variance between body fat percentage measured by smart phone applicaiton compared to body fat percentage as measured by DEXA scan

Secondary Outcome Measures

Name	Time	Method
abdominal circumference	8 months	Analysis will be undertaken to see if the variance between application and dual energy x-ray absorptiometry is reduced when the abdominal circumference is included in the application or whether inclusion of abdominal circumference does not reduce the variance.
