Weight Change
EVENTS
At baseline, 3 months, and 6 months, weight values were extracted directly from the WW beta app, which synchronized to the WW Bluetooth scale. In rare events where a participant was unable to get their scale to pair with the WW app, participants uploaded a screenshot of their weight through REDCap (Research Electronic Data Capture; Vanderbilt University) using a private link. Participants were asked to step on the scale in the morning, undressed and after voiding. Weight was recorded in pounds directly from the Bluetooth scale mailed to participants. Weight change was defined as the difference between baseline weight and the weight at 3 months or 6 months. Percentage weight change was calculated as weight change divided by baseline weight and multiplied by 100.
