VANCOUVER (Reuters) - China's Nanjing will host the second edition of the summer Youth Olympic Games, the International Olympic Committee decided on Wednesday.

Singapore was picked to host the inaugural Youth Olympics later this year while Austria's Innsbruck was chosen as the site of the first winter Youth Games in 2012.

The IOC established the Youth Olympics in an effort to shore up dwindling support for the Games among younger people and to fight obesity among teenagers.

Singapore will host about 3,200 athletes, aged 14-18, competing in 26 sports and the Youth Games are expected to cost about $30 million. Some 800 judges, referees and delegation officials for the summer editions will also be young people.
