people suffered from depression in 2015, according to a report by the World Health Organization in February. This is more than 4 percent of the world's population.

　　Depression is described by the WHO as a mental disorder. It has several symptoms including sadness, loss of interest and feelings of low self-worth. In severe cases, depression may even lead to suicide.

　　The number of people living with depression is increasing. The WHO reported a rise of 18.4 percent between 2005 and 2015. Young people are a group known to suffer with depression. "The pressures on today's youth are like no other generation, perhaps," Dan Chisholm, an official of WHO, told Reuters.

　　In China, depression among young people is on the rise, Zhu Zhuohong, a psychology professor with the Chinese Academy of Sciences, told Xinhua News Agency. Competition to outperform others, especially in education, can cause a lot of pressure for Chinese youth.

　　Almost 1.2 million Chinese people aged 15 to 24 suffer from depression, according to a report released by British science journal The Lancet in May.

　　Luckily, more and more efforts are being made to deal with this problem. This year's World Health Day, held on April 7, will focus on depression. The day will highlight the "Depression: let's talk" campaign. The campaign aims to make sure that people with depression both seek and get help.
