Depression is more common among women than among men. Major depression and dysthymia (long-lasting low grade depression) affect twice as many women as men.
Before adolescence, there is little difference in the rate of depression in boys and girls. But between the ages of 11 and 13 there is a precipitous rise in depression rates for girls. By the age of 15, females are twice as likely to have experienced a major depressive episode as males. This comes at a time in adolescence when roles and expectations change dramatically.
Biological, lifecycle, hormonal and psychosocial factors unique to women may be linked to women's higher depression rate.
It appears that females hormones, such as estrogen and progesterone, directly affect brain chemistry that controls emotions and mood. For example, women are particularly vulnerable to depression after giving birth, when hormonal and physical changes, along with the new responsibility of caring for a newborn, can be overwhelming.
During the transition into menopause, some women experience an increased risk for depression. Scientists are exploring how the cyclical rise and fall of estrogen and other hormones may affect the brain chemistry that is associated with depressive illness.
Finally, many women face the additional stresses of work and home responsibilities, caring for children and aging parents, abuse, poverty, and relationship strains. It remains unclear why some women faced with enormous challenges develop depression, while others with similar challenges do not.
What is clear is that regardless of the contributing factors, depression is a highly treatable illness.
Women's reproductive events include the menstrual cycle, pregnancy, the postpregnancy period, infertility, menopause, and sometimes, the decision not to have children. These events bring fluctuations in mood that for some women include depression.
Studies show that women molested as children are more likely to have clinical depression at some time in their lives than those with no such history. In addition, several studies show a higher incidence of depression among women who have been raped as adolescents or adults. Since far more women than men were sexually abused as children, these findings are relevant.
Women who experience other commonly occurring forms of abuse, such as physical abuse and sexual harassment on the job, also may experience higher rates of depression. Abuse may lead to depression by fostering low self-esteem, a sense of helplessness, self-blame, and social isolation. There may be biological and environmental risk factors for depression resulting from growing up in a dysfunctional family.
As with younger age groups, more elderly women than men suffer from depressive illness. Similarly, for all age groups, being unmarried (which includes widowhood) is also a risk factor for depression. Most important, depression should not be dismissed as a normal consequence of the physical, social, and economic problems of later life. In fact, studies show that most older people feel satisfied with their lives.
