The present study is a prospective randomized control trial. A total of 80 patients who underwent total thyroidectomy for thyroid cancer is included. Fifty-four patients are randomly assigned to the digital lifestyle management group and the other 26 patients are assigned to the non-digital lifestyle management group.
In the experimental group (digital lifestyle management group), the patients will use this application for the first 4 months with Noom applications with 1:1 personalized coaching intervention, and then, use this app by self-help program without coaching intervention. The digital lifestyle management program will record the patient's meals, exercise, steps taken, reading articles, and give feedback to each patient. In order to monitor the psychological state and quality of life of the patients, online questionnaires will be provided.
In the control group (non-digital lifestyle management group), the patients will get the conventional postoperative care protocol without using the Noom application. To investigate the weight change and quality of life, variables are collected at baseline, 4 months, and 6 months after surgery.
