Some parents choose to give their children medicine and injections to inhibit bone age, in an attempt to close bones more slowly and "buy time" for their children to grow taller. Xie Lichun, deputy chief physician of pediatrics at the Huangpu Campus of the Third Affiliated Hospital of Guangzhou Medical University, told the Yangcheng Evening News reporter: "As a doctor, I don't recommend doing this routinely" The side effects of taking drugs and injections are difficult to predict, he said.
