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.
Interventions
DIAGNOSTIC_TESTComputer based vision application by video
patients will be tested by computer based analysis of a video as well as by dexa scan.
RADIATIONwhole body dual energy x-ray absorptiometry scan
subjects will receive a whole body dual energy x-ray absorptiometry scan to measure their body fat percentage

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
