She will receive a prize of 5,000 euros, a spokesman for the competition told a news conference Friday.
"This year, the competition is called 'The History of My Diabetes,'" the spokesman said. "The competition allows children to show in drawings how their outlook changed as the illness progressed."
This is the third annual competition of its kind. Since its founding, there have been a total of more than 5,000 drawings by children from 25 countries.
The drawings have been compiled into a book, German Stories, published for children suffering from diabetes. All children with diabetes in Moscow will receive a copy of the book on November 14, World Diabetes Day.
The book will then go on sale in stores with 5% of revenues being donated to the Volgograd branch of the Russian Children's Fund for children suffering from diabetes.
