BEIJING, Sept. 11 (Xinhua) -- China's health authority on Friday unveiled an action plan for depression prevention and treatment, particularly among vulnerable groups including adolescents, pregnant women, seniors and those with high-stress jobs.

The action plan set a target whereby depression prevention knowledge will have been popularized among 80 percent of the general population and 85 percent of students by 2022, according to the National Health Commission.
