Toronto, Approximately one in eight older adults developed depression for the first time during the pandemic, according to a study conducted in Canada. For those who had experienced depression in the past, the numbers were even worse, the study said. By the autumn of 2020 almost half (45 per cent) of this group of 20,000 older adults reported being depressed. The researchers from University of Toronto analysed responses from the Canadian Longitudinal Study on Aging, which collected data from participants for an average of seven years, the study said.
