Gestational Weight Gain and Pregnancy Outcomes for 919 Twin Pregnancies in China

919 twin pregnant women and 1838 newborns from deliveries between 2022 and 2023 in China were studied. The data was collected by Huiyuan Zhu and published on figshare under a CC-BY-4.0 license. It examines the association between gestational weight gain and outcomes like preterm birth, hypertensive disorders, and infant size across different pre-pregnancy BMI categories.

Use Cases

• Modeling the risk of preterm birth based on gestational weight gain rate and pre-pregnancy BMI.
• Analyzing the association between inadequate weight gain and the likelihood of Small for Gestational Age infants.
• Investigating the link between excessive weight gain and hypertensive disorders of pregnancy.
• Studying the correlation between excessive weight gain and Large for Gestational Age infants.

Strengths

• Includes data on 919 twin pregnancies and 1838 newborns.
• Provides specific adjusted odds ratios (aOR) for key associations, such as aOR=2.10 for inadequate weight gain and SGA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the study's location in China.
