About this study

The study will conduct a multicenter prospective clinical cohort study to collect comprehensive health information and essential specimens from pre-pregnancy to postpartum offspring development. We will combine the reproductive medicine with the big data technologies and cloud computing to explore the key factors which will induce the occurrence the reproductive disorders and effect the health of women and offspring. Based on the discovery of the cohort study, we will construct a prediction model for improvement of ART,optimizing the effectiveness and safety of ART.

Read the detailed description

Safeguarding the health of women and children is an important part of The Healthy China 2030 Plan. Precisely controlling the fertility process will help to improve the quality of national population. Lots of studies have reported that environmental exposure, lifestyle, diet and other factors are related to fertility, female pregnancy and postpartum health, and offspring development. Some studies have found that assisted reproductive technology (ART) represents an increased risk of epigenetic-related diseases or birth defects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. live birth rate

    Number of women with live births / number of women randomized to the specific group.

    Measured: 1 day after delivery

  2. birth weight

    Weight of newborns at delivery.

    Measured: 1 day after delivery

  3. weight

    the weight of offspring

    Measured: Change from the date of delivery up to 2 years after delivery

  4. height

    the height of offspring

    Measured: Change from the date of delivery up to 2 years after delivery

  5. Incidence of mental diseases and metabolic dysfunction

    Measured: from the date of delivery up to 2 years after delivery

Secondary outcomes (4)
  1. implantation rate

    Implantation rate was defined as the percentage of fetal heart beat among total transferred embryos at 12 weeks' gestational age.

    Measured: 11-12 weeks after embryo transfer

  2. clinical pregnancy rate

    Clinical pregnancy was defined as an observation of gestational sac via ultrasonography.

    Measured: 6 weeks after embryo transfer

  3. preterm birth rate

    preterm birth is defined as gestational weeks between 28 to 37.

    Measured: 28 gestational weeks to 37 gestational weeks

  4. neonatal complication rate

    Neonatal complication includes neonatal respiratory disorders, neonatal cerebral palsy, neonatal encephalopathy and other disease that should been sent into neonatal ICU.

    Measured: 1 day after delivery
