Effects of Axivity 3.0-based management model on pregnant women with gestational diabetes mellitus

Aims: To evaluate the effect of a precision exercise management model based on the Axivity 3.0 device on physical activity levels, glucose control, and delivery outcomes in patients with gestational diabetes mellitus (GDM). Patients and methods: This study employed a randomized controlled design. One hundred patients with GDM from Hangzhou Women's Hospital from May 2020 to September 2020 who received regular obstetric follow-ups and intended to deliver in our hospital were recruited. Patients were randomly divided into a control group (conventional health education model of exercise during pregnancy) and a test group (received the Axivity 3.0-based management model combined with health education). A general information questionnaire, Pregnancy Exercise Self-efficacy Scale (P-ESES), Pregnancy Physical Activity Questionnaire; physical activity levels; fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hPG); the duration of the first and second stages of labor for vaginally-delivering patients were assessed. Results: After the 4-week intervention, the total P-ESES score was significantly higher in the test group (median 39, IQR 36-42) than in the control group (median 36, IQR 33-38; p < 0.001). Weekly moderate-to-vigorous physical activity (MVPA) time increased to 75.95 ± 28.30 minutes in the test group versus 56.24 ± 23.66 minutes in the control group (mean difference: 19.71 minutes/week, p=0.001). At delivery, fasting blood glucose (FBG) and 2-hour postprandial glucose (2hPG) levels were significantly lower in the test group (FBG: 4.47 ± 0.47 mmol/L; 2hPG: 5.40 ± 0.56 mmol/L) compared to the control group (FBG: 4.82 ± 0.41 mmol/L, p=0.001; 2hPG: 6.02 ± 0.63 mmol/L, p
