| Outline of Research at the Start |
This project will collect, during two years, data on gestational weight gain and pregnancy/birth outcomes to assess the new GWG guidelines and growth charts using a healthcare application and health record of two hospitals.
|
| Outline of Annual Research Achievements |
This project aims to demonstrate the effectiveness of the new gestational weight gain (GWG) guidelines and growth charts by estimating the percentage of women who achieved the new recommended GWG range between 2020 and 2023.
We collected data from a healthcare application, LunaLuna Baby (ルナルナベビーMTI Ltd.) for its large number of users in the general population. About 7,500,000 daily weight records of about 83,400 children for 82,500 mothers were received, and cleaned up. Primarily analysis show an evolution of pregnancy weight gain between 2020 and 2023 after the change in guidelines in 2021. A confirmation with hospital data are needed, and the impact on child outcomes.

| Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Collecting data from hospitals is taking more time than expected. Nevertheless, we make progress with data from LunaLuna Baby application. Data was cleaned and primarily analysis was done.
|
| Strategy for Future Research Activity |
Finalize analyses with the Lunaluna App and write up a manuscript. We hope also to collect data from hospital sources in the following months.
