More than two in five (44%) Canadian seniors living in residential care homes are diagnosed with or have symptoms of depression, according to a new study released by the Canadian Institute for Health Information (CIHI).

The study, Depression Among Seniors in Residential Care, is one of the largest of its kind in Canada to examine the prevalence of depression and the impact it has on persons living in residential care facilities, such as long-term care, nursing or personal care homes. Based on data from CIHI’s Continuing Care Reporting System, the study included nearly 50,000 residents age 65 and older across four provinces and one territory (Nova Scotia, Ontario, Manitoba, Saskatchewan and the Yukon).

CIHI’s study found that, while about one in four (26%) seniors living in a residential care facility had a diagnosis of depression, a further one in five (18%) had symptoms of depression with no documented diagnosis. Residents were considered to have symptoms of depression if they had a score of at least 3 on the Depression Rating Scale, which measures symptoms such as persistent anger, tearfulness and repetitive anxiety.
