Canadian study finds that antidepressant use has increased in people with major depression over the past decade.

Assessment: Data were collected every two years on the frequency of healthcare use in relation to major depression as part of the National Population Health Survey. Episodes of depression in the year preceding assessment were identified using the Composite International Diagnostic Interview Short Form for Major Depression. Any medications used in the two days preceding the interview were recorded and participants were asked if they had consulted a health professional about their mental health and about the frequency of these consultations.
