Clinical Trial Summary

The purpose of this study is to see if photos taken from home can accurately let physicians know the height, abdominal circumference, and wrist circumference of children, and how these measurements relate to in-person measurements.

Clinical Trial Description

This study will occur in two distinct parts. Children age 2-18 who present to Mayo 16 for an outpatient clinic appointment will be considered for participation in the study. Patients eligible for the study will receive a portal message the day prior to their appointment informing them of the option to take place in the study as well as instructions on how to measure height, abdominal circumference, and wrist circumference, and how to obtain and submit digital photographs. Participants can submit photographs and home measurements either before or after the in clinic measurements and photographs have been obtained. Those willing to participate will sign a parental consent form and a child assent form. Consent and assent forms can be seen in the supplemental documents. At Home Participants will be given written instructions asking for 2 photographs to be submitted via the patient portal and for measurements of height, abdominal circumference, and wrist circumference to be obtained using a home tape measure. Detailed patient instructions will be shared. Study Visit Traditional Anthropometric Measurements Participant will have a height measurement using a calibrated stadiometer, a weight measurement taken on a scale, a waist circumference taken at the umbilicus, and a wrist circumference will be taken while seated on the dominant wrist over the Lister tubercle of the radius and over the distal ulna as described by Luordi et al.[5] Participants 5 years of age and older who are 90cm and greater will have body composition assessed by impedance. Bioelectrical impedance is not in any way uncomfortable and does not expose the participant to any radiation. Participant measurements will be recorded in the patient record and a secure excel document or in RedCap. Recruited patient MRNs will be documented in a secure excel document or in RedCap. Digital Photography Measurements The participant will be instructed to take off any thick outer layers and leave on shirt and pants. Tops will be gathered to make cloth tight to body. The participant will stand next to an 8 ½" x 11" piece of paper taped to a wall, to use as a reference for linear regression calculations. The participant will have a photograph taken in the "Frankfurt plane" with lower border of the eyes in line with the external ear canal, palms facing forward and arms to the side, while taking a deep breath at the time of the photograph to have optimal stretching [7]. A photograph will be taken from the side in the sagittal plane with palms facing down and arms outstretched in front of the patient while taking a deep breath at the time of the photograph for optimal stretching. These photos will be taken by a trained member of the research team. ;
