It is possible to develop depression with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing depression. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.

In recent years, researchers have found that physical changes in the body can be accompanied by mental changes. Chronic conditions (eg, stroke, heart attack, cancer, HIV/AIDS, Parkinson’s disease, kidney disease, type 2 diabetes) can increase the risk of depression. Chronic pain is also known to be associated with depression.

A history of one or more previous episodes of depression significantly increases the risk of another episode.

Women experience depression about twice as often as men. Hormonal factors may contribute to the increased rate of depression in women, particularly during premenstrual changes, pregnancy, miscarriage, postpartum period, and menopause. Many women face additional stresses, such as having responsibilities at work and home and being the primary caretaker for children and aging parents.

Chronic sleep problems, like insomnia, are strongly associated with depression and require treatment.
