Weight Gain Recommendations for Chinese Women With Gestational Diabetes Mellitus
The 2009 IOM recommendation value for weight gain during pregnancy is widely used. Due to the
 unclear relationship between gestational diabetes mellitus and weight gain during pregnancy
 when formulating this recommendation value, pregnant women with gestational diabetes mellitus
 were excluded from the study population. Control of appropriate weight gain and control of
 blood glucose stability is an important part of GDM management in pregnant women. The
 incidence of GDM in China is about 15%-20%, and the number of pregnant women with GDM ranks
 first in the world. For the sake of the current and long-term health of maternal and infant,
 it is of great significance to explore the appropriate weight gain range and formulate the
 recommended value for GDM pregnant women as an independent population. This project intends
 to use prospective cohort study of combining the observation of pregnant women with
 gestational diabetes blood sugar and weight changes, through the comparison of normal
 pregnant women suitable scope of weight gain, analyzes its influence on adverse pregnancy
 outcomes, increased the weight of gestational diabetes women recommended value is put
 forward, and combined with the Delphi expert consultation method for evaluation.
This project is a prospective cohort study designed to investigated the changes in blood
 glucose and body weight in women with gestational diabetes during pregnancy. The study aimed
 to enroll 4000 participants, using health management app in addition to routine prenatal
 care. Researchers screen subjects strictly according to the exclusion and inclusion criteria
 and those who interested sign the informed consent. participants completed baseline
 questionnaire and dietary questionnaire at app under the instruction of researchers. Pregnant
 women come back for follow up-visit every 2 weeks until delivery. If anyone doesn't upload
 the weight data for a week and doesn't respond to the phone call from the researchers, she
 will be regarded as lost follow-up,the number of lost follow-up cases are supplemented by
 increasing the enrollment. Data analysis and result output finally.

 Besides, part of the study conducted in Beijing has some special points which don't exsit in
 large cohort study: participants equipment dynamic blood glucose monitor for glycemic control
 and their blood samples and stool samples will be collected at 24-28, 32 and 36 gestational
 weeks,respectively.

 Based on the description of weight gain range of pregnant women with normal blood glucose,
 the influence of weight gain on adverse pregnancy outcome was analyzed, and the recommended
 weight gain value for women with gestational diabetes was proposed in combination with Delphi
 expert consultation method.
