Primary school students in China experienced more depressive symptoms and made more suicide attempts after schools closed for the pandemic, a new study found. When Covid-19 hit China in January, the Ministry of Education postponed the start of spring semester to late April. That closure separated children from their friends and their broader community network, and seems to have had an impact on their mental well-being. The study, published Friday in JAMA Network Open, compared reports of mental health problems in November -- before the pandemic started -- to mid-May, two weeks into the new spring semester when schools had re-opened.
