Depression is not only the most common women's mental health problem but may be more persistent in women than men. According to WHO about 10% of pregnant women and 13% of women who have just given birth experience a mental disorder, primarily depression.

On average, 1 in 8 men will have depression and 1 in 5 men will experience anxiety at some stage of their lives. Prolonged or excessive job stress is a risk factor for mental health problems, and accounts for 13 per cent of depression in working men

Between 10 and 15 percent of older adults experience depression, and approximately 10 percent experience anxiety. Rates of depression among people living in residential aged-care facilities are believed to be much higher, at around 35 per cent.
