The height of the Chinese is the highest in East Asia, so who is at the bottom? (The Paper)

The Paper (China) published an article that referenced the IFPRI research on stunting in children, Evaluation of linear growth at higher altitudes (Jama Pediatrics). The study analyzed the height and age data of more than 950,000 children from 59 countries and showed that the growth rate of children living in an ideal family environment is the same as that of the median children's growth standard established by the WHO, but only in areas with an altitude of less than 500 meters. At an altitude of 500 meters, the average age and height of children deviated significantly from the growth curve of children in the reference population. Republished in MedSci (China).
