Westlake Precision Birth Cohort (WeBirth)

Primary objective: Precision nutrition in women with gestational diabetes.

The Westlake Precision Birth Cohort (WeBirth) is a prospective birth cohort study based on pregnant women with gestational diabetes mellitus (GDM) and their offspring. The WeBirth aims to investigate precision nutrition for GDM patients (n~2000) by incorporating standardized meal tests and continuous glucose monitoring to test their personalized glucose response to diet.


1. Diversified information and biological samples are collected, and continuous glucose monitoring and physical activity record are conducted using wearable devices, with the inclusion of standard meal tests in the study design.

2. Our primary objective is to study precision nutrition in women with gestational diabetes by integrating dietary intake, continuous glycemic performance, physical activity monitoring and multiomics data.
