Increase in symptoms of depression and anxiety worldwide due to COVID-19

Results from a consumer survey across 11 countries
Symptom of Depression 37%→48% Symptom of Anxiety 33%→53%

Social Information Service Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo, President: Takashi Makita) has released the results of the impact of COVID-19 on adult consumers around the world based on the National Health and Wellness Survey (NHWS)1 and the COVID-19 Recontact Survey2, conducted in 11 countries around the world,. Both were conducted by the affiliated US company KANTAR Co. Ltd.


NHWS is a large-scale health survey conducted in 11 countries around the world. It asks about the health characteristics and quality of life of consumers, the prevalence of more than 165 diseases and symptoms, the treatment of affected people, and the situation of the individual. The effects of COVID-19 on depression and anxiety symptoms were confirmed by comparing the latest wave of NHWS against the results from the COVID-19 Recontact Survey for the same respondents..The COVID-19 Recontact Survey also asked additional questions about online medical care (telemedicine) and other impacts due to COVID-19.


Using the PHQ-93 scale for depressive symptoms and the GAD-74 scale for anxiety symptoms, we calculated the ratios from mild to severe (mild-severe). The result showed the average value in 11 countries around the world increased: depression increased by from 37% in 2019 to 48% in 2020. Anxiety increased from 33% in 2019 to 53% in 2020.


In addition, according to the survey in 2020, 41% of consumers in the 11 countries canceled / postponed or changed to online medical treatment (telemedicine). The content of medical treatment was less urgent, such as regular medical consultations and examinations.

On the other hand, 27% of doctors recommended online medical treatment (telemedicine), which is more than 1 in 4 people in 11 countries overall.


This tendency is high in Europe and the United States. United States was 55%, in Europe, country differences were confirmed from 32% in the United Kingdom to 63% in Spain. In East Asia, urban China was slightly higher at 40%, but South Korea was 25%, and Taiwan was 24%, which was lower than Europe and the United States, and Japan was the lowest at 12%. Although it is recognized that the consultation restraint of patients in Japan is significant, it is suggested that the situation in Europe and the United States is more serious.


COVID-19, which has become a global pandemic, is said to have brought new normal to society. Under this situation, it has become clear that people around the world who live at risk of infection have a higher proportion having mental disease. It may suggest a discussion about the need for social follow-up to this mental disease problem.
