Depression in Women:
What Every Woman Should Know

Life is full of emotional ups and downs. But when the "down" times are long lasting or interfere with your ability to function, you may be suffering from a common, serious illness- depression. Clinical depression (major depression) affects mood, mind, body, and behavior. Research has shown that in the United States about 19 million people-one in ten adults-experience depression each year, and nearly two-thirds do not get the help they need. Treatment can alleviate the symptoms in over 80 percent of the cases. Yet, because it often goes unrecognized, depression continues to cause unnecessary suffering.

Depression is a pervasive and impairing illness that affects both women and men, but women experience depression at roughly twice the rate of men. Researchers continue to explore how special issues unique to women-biological, life cycle, and psycho-social-may be associated with women's higher rate of depression.

No two people become depressed in exactly the same way. Many people have only some of the symptoms, varying in severity and duration. For some, symptoms occur in time-limited episodes; for others, symptoms can be present for long periods if no treatment is sought. Having some depressive symptoms does not mean a person is clinically depressed. For example, it is not unusual for those who have lost a loved one to feel sad, helpless, and disinterested in regular activities. Only when these symptoms persist for an unusually long time is there reason to suspect that grief has become depressive illness. Similarly, living with the stress of potential layoffs, heavy workloads, or financial or family problems may cause irritability and "the blues." Up to a point, such feelings are simply a part of human experience. But when these feelings increase in duration and intensity and an individual is unable to function as usual, what seemed a temporary mood may have become a clinical illness.

Women Are At Greater Risk For Depression Than Men

Major depression and dysthymia affect twice as many women as men. This two-to-one ratio exists regardless of racial and ethnic background or economic status. The same ratio has been reported in ten other countries all over the world. Men and women have about the same rate of bipolar disorder (manic-depression), though its course in women typically has more depressive and fewer manic episodes. Also, a greater number of women have the rapid cycling form of bipolar disorder, which may be more resistant to standard treatments.

A variety of factors unique to women's lives are suspected to play a role in developing depression. Research is focused on understanding these, including: reproductive, hormonal, genetic or other biological factors; abuse and oppression; interpersonal factors; and certain psychological and personality characteristics. And yet, the specific causes of depression in women remain unclear; many women exposed to these factors do not develop depression. What is clear is that regardless of the contributing factors, depression is a highly treatable illness.

The Many Dimensions of Depression in Women

Investigators are focusing on the following areas in their study of depression in women:

The Issues of Adolescence

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. The stresses of adolescence include forming an identity, emerging sexuality, separating from parents, and making decisions for the first time, along with other physical, intellectual, and hormonal changes. These stresses are generally different for boys and girls, and may be associated more often with depression in females. Studies show that female high school students have significantly higher rates of depression, anxiety disorders, eating disorders, and adjustment disorders than male students, who have higher rates of disruptive behavior disorders.

Adulthood: Relationships and Work Roles

Stress in general can contribute to depression in persons biologically vulnerable to the illness. Some have theorized that higher incidence of depression in women is not due to greater vulnerability, but to the particular stresses that many women face. These stresses include major responsibilities at home and work, single parenthood, and caring for children and aging parents. How these factors may uniquely affect women is not yet fully understood.

For both women and men, rates of major depression are highest among the separated and divorced, and lowest among the married, while remaining always higher for women than for men. The quality of a marriage, however, may contribute significantly to depression. Lack of an intimate, confiding relationship, as well as overt marital disputes, have been shown to be related to depression in women. In fact, rates of depression were shown to be highest among unhappily married women.

Reproductive Events

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. Researchers have confirmed that hormones have an effect on the brain chemistry that controls emotions and mood; a specific biological mechanism explaining hormonal involvement is not known, however.

Many women experience certain behavioral and physical changes associated with phases of their menstrual cycles. In some women, these changes are severe, occur regularly, and include depressed feelings, irritability, and other emotional and physical changes. Called premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD), the changes typically begin after ovulation and become gradually worse until menstruation starts. 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.

Postpartum mood changes can range from transient "blues" immediately following childbirth to an episode of major depression to severe, incapacitating, psychotic depression. Studies suggest that women who experience major depression after childbirth very often have had prior depressive episodes even though they may not have been diagnosed and treated.

Pregnancy (if it is desired) seldom contributes to depression, and having an abortion does not appear to lead to a higher incidence of depression. Women with infertility problems may be subject to extreme anxiety or sadness, though it is unclear if this contributes to a higher rate of depressive illness. In addition, motherhood may be a time of heightened risk for depression because of the stress and demands it imposes.

Menopause, in general, is not asssociated with an increased risk of depression. In fact, while once considered a unique disorder, research has shown that depressive illness at menopause is no different than at other ages. The women more vulnerable to change-of-life depression are those with a history of past depressive episodes.

Specific Cultural Considerations

As for depression in general, the prevalence rate of depression in African American and Hispanic women remains about twice that of men. There is some indication, however, that major depression and dysthymia may be diagnosed less frequently in African American and slightly more frequently in Hispanic than in Caucasian women. Prevalence information for other racial and ethnic groups is not definitive.

Possible differences in symptom presentation may affect the way depression is recognized and diagnosed among minorities. For example, African Americans are more likely to report somatic symptoms, such as appetite change and body aches and pains. In addition, people from various cultural backgrounds may view depressive symptoms in different ways. Such factors should be considered when working with women from special populations.

Victimization

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. At present, more research is needed to understand whether victimization is connected specifically to depression.

Poverty

Women and children represent seventy-five percent of the U.S. population considered poor. Low economic status brings with it many stresses, including isolation, uncertainty, frequent negative events, and poor access to helpful resources. Sadness and low morale are more common among persons with low incomes and those lacking social supports. But research has not yet established whether depressive illnesses are more prevalent among those facing environmental stressors such as these.

Depression in Later Adulthood

At one time, it was commonly thought that women were particularly vulnerable to depression when their children left home and they were confronted with "empty nest syndrome" and experienced a profound loss of purpose and identity. However, studies show no increase in depressive illness among women at this stage of life.

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.

About 800,000 persons are widowed each year. Most of them are older, female, and experience varying degrees of depressive symptomatology. Most do not need formal treatment, but those who are moderately or severely sad appear to benefit from self-help groups or various psychosocial treatments. However, a third of widows/widowers do meet criteria for major depressive episode in the first month after the death, and half of these remain clinically depressed 1 year later. These depressions respond to standard antidepressant treatments, although research on when to start treatment or how medications should be combined with psychosocial treatments is still in its early stages.
