Protest-hit Hong Kong sees surge in depression, PTSD – study

HONG KONG, China – Nearly one in 3 adults in Hong Kong reported symptoms of post-traumatic stress disorder during months of often violent social unrest in the city, according to a study published in The Lancet medical journal Friday, January 10.

And around one in 10 had symptoms of probable depression, figures comparable to those seen in areas of armed conflict or following terrorist attacks, the decade-long study led by researchers from the University of Hong Kong found.

Prevalence of PTSD symptoms was 6 times higher than after the last major pro-democracy “Occupy” protests in 2014, rising from about 5% in March 2015 to almost 32% in September-November 2019.

The increase corresponds to an additional 1·9 million adults with PTSD symptoms in the city of 7.4 million.

Up to 11% of adults reported symptoms of depression, from around 2% before the Occupy protests, and 6.5% in 2017, the study estimated.

“One in 5 adults now report probable depression or suspected PTSD, which is comparable to those experiencing armed conflicts, large-scale disasters, or terrorist attacks,” the study said. (READ: How Hong Kong protests are affecting its economy)

The researchers also found that heavy use of social media to follow socio-political events appeared to increase the risk of probable depression and suspected PTSD.

“Hong Kong is under-resourced to deal with this excess mental health burden,” said professor Gabriel Leung, dean of medicine at the University of Hong Kong, who co-led the research. 

The researchers used numerous surveys carried out on 18,000 people between 2009 and 2019 in what they said was the largest and longest study of the population-wide impact of social unrest on mental health in the world. 

They warned that their findings may underestimate the extent of mental health problems as they did not include under-18s, who make up a large proportion of protestors.

Hong Kong has been battered by 7 months of unrest, with millions marching and frequent violent confrontations in which police have fired tear gas and rubber bullets, while protesters have responded with petrol bombs.

“With social unrest rising around the world, including in major cities such as Barcelona, Delhi, Paris, and Santiago in 2019, the issue of how social unrest impacts population mental health is of great public-health importance,” said Michael Ni from the University of Hong Kong, who co-led the research. – Rappler.com
