Mental health crisis under COVID-19 pandemic in Hong Kong, China.

OBJECTIVES: To compare the mental health burden before and during the COVID-19 outbreak and identified vulnerable groups by sociodemographic factors. METHODS: We analyzed repeated cross-sectional data from Hong Kong Family and Health Information Trend Survey (FHInTS) in 2016 (N = 4036) and 2017 (N = 4051) and COVID-19 Health Information Survey (CoVHInS) in April 9 to 23, 2020 (N = 1501) using population-based random samples of general adults by landline telephone and online panel. Stress (Perceived Stress Scale 4), anxiety symptoms (General Anxiety Disorders 2), depression symptoms (Patient Health Questionnaire-2), subjective happiness (4-point Likert item), and sociodemographic were collected. RESULTS: Compared with 2016 and 2017, the stress level increased by 28.3%, prevalence of anxiety increased by 42.3% and the depression symptoms and unhappiness have doubled (all p for trends <0.001) during the COVID-19 outbreak. The increases in stress level were significantly larger among older and less educated respondents (P for interactions <0.001). CONCLUSION: Hong Kong had a mental health emergency even with no lockdown and well-managed outbreaks. Older and under-privileged people will suffer most. Public mental health interventions are urgently needed particularly for the older adults and individuals with primary or lower education attainment.
