A Prospective Randomized Controlled Trial of Mobile Medical Used for Management of Pregnant Women

• Mobile technology and equipment based on Internet and communications technology have revolutionized the content and manner of social interaction and services. Mobile medical care has just started, the relevant platform and service is still immature, not standardized, poor satisfaction, low efficiency, its value and effectiveness of health management lack of clear theoretical support and data description. In this study, based on the multi-center prospective randomized controlled study, we constructed a large-scale maternal health service platform and a systematic standardized maternal health management model to carry out personalized maternal health management and mobile health services. Mobile medical effects validation, and further improve the mobile medical platform.

This study will verify the value of mobile health care for maternal health management, to establish a standardized standard mobile medical model, to further improve the level of domestic maternal health management and improve the quality of maternal and child health management.

• Most gestational diabetes mellitus (GDM) can be well controlled by health education and life style management, expecting a better pregnancy outcome. But standard clinic prenatal care which consist of clinic visit every two weeks may not give full play to the effects of GDM management. Telemedicine shows its potential to fill this gap. A multicenter, randomized controlled trial was designed to investigate whether health education and life style management through WeChat group chat was more effective in controlling blood glucose (BG) than standard clinic prenatal care in women with GDM. Women with GDM diagnosed by oral glucose tolerance test between 23-30+6 gestational weeks were randomized to a WeChat group chat-based blood glucose management group or routine clinic prenatal care. In PUMCH, investigators also equip CGM for m-health group allowing a more detailed BG information. The primary outcome was change of glycemic qualification rate during follow up period in both groups. The second outcome was pregnancy outcomes. Also, a case control study is designed to compare the glucose control status between rice-richen meal and wheaten-richen meal, and all other macronutrients and micronutrients are all calculated and same between two groups, which may provide more clues for type of carbohydrate recommendation for Chinese women with GDM.
