Abstract:
To assess the effectiveness of using a smartphone application for weight loss as well as a change in health-related behavior in patients with colorectal polyps over 3 months.Randomized, controlled pilot trial.The Department of Family Medicine, Myongji Hospital, Hanyang University College of Medicine, Goyang, Korea.Adults aged 25–65 years who were diagnosed with colorectal polyps.A comparison of smartphone application data, with exercise and food intake diary data over 3 months.Primary outcomes were weight reduction and an increase in physical activity. Secondary outcomes included changes in dietary intake, such as that of vegetables, fruits, and fatty food.Student t test was used for continuous variables, and chi-square test for categorical variables.Participants using the smartphone application experienced significant weight reduction compared with participants in the control group (mean change = –1.25 vs –0.42 kg; SD = 0.42 vs 1.23 kg). Moreover, use of the application and strict adherence to it significantly increased the level of physical activity (mean change = 1.57 vs 0.71 strenuous exercises/wk; SD = 1.09 vs 0.96 strenuous exercise/wk).Smartphone applications could be potential tools for weight control and physical activity in patients with colorectal polyps. Future larger randomized, controlled trials over a prolonged period are warranted to confirm these findings.
