Gestational Weight Gain and Pregnancy Outcomes for Twin Births in China, 2022-2023

A dataset of 919 twin pregnant women and 1838 newborns from China collected between 2022 and 2023. It examines the association between gestational weight gain and adverse pregnancy outcomes across different pre-pregnancy BMI categories. The data was analyzed using logistic regression models to estimate risks.

Use Cases

• Assessing the risk of preterm birth based on inadequate gestational weight gain.
• Evaluating the association between excessive weight gain and hypertensive disorders of pregnancy.
• Analyzing the likelihood of small or large for gestational age infants relative to weight gain patterns.
• Developing personalized prenatal counseling models for twin pregnancies.

Strengths

• Includes data on 919 twin pregnancies and 1838 newborns, providing a specific population focus.
• Analysis includes adjusted odds ratios with 95% confidence intervals for key outcomes like preterm birth and hypertensive disorders.
• Data collection timeframe is explicitly stated as 2022 to 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data table is unknown, which may limit suitability assessment.
• The dataset is small in size (91.6 KB), indicating limited scope.
