Data collection
gastrointestinal or gynecological surgery
CHRONIC DISEASES
A trained assistant at the gastroenterology and liver research center initially registered individuals. Then the socioeconomic characteristics, social history (drug use, smoking, and alcohol consumption), chief complaint (reason for referral), defecation status, history of gastrointestinal or gynecological surgery, history of chronic diseases, history of previous colonoscopies and the number of footsteps (recorded by the smart band) were completed by a trained questioner. Also, during the colonoscopy, the rest of the questionnaire was completed by two trained questioners, including the time of the colonoscopy and the time of reaching the cecum. A gastroenterologist ultimately determined the final diagnosis, Boston score, and future colonoscopy status.
