We excited to launch our new INTERGROWTH-21st app, providing a user-friendly platform to assess newborn size at birth from 24 weeks gestational age and to track preterm growth until week 64 postmenstrual age, where our standards merge with the WHO Child Growth standards. 

Our app is freely available for download on phones, tablets, and computers, both on iOS and Google Play devices.

In new ground-breaking study published in Lancet Global Health, using INTERGROWTH-21st standards, researchers present findings challenging conventional wisdom regarding the impact of household air pollution on fetal growth.
