Women's Health in the United States and Beyond |
In recent years, interest in and commitment to the improvement of womens health have burgeoned in the United States and around the world.1,2 Over the past twenty-five years in the United States, the womens advocacy community has successfully argued for a better appreciation of the health of women and increased understanding of and sensitivity about womens health care needs. This longstanding advocacy effort seemed to blossom more fully in the scientific and health care communities during the 1990s, with unprecedented levels of interest and resources dedicated to elucidating sex3 (biological characteristics of being female or male) and gender (responses to societal influences based upon sex) differences and similarities in health and disease, as well as in normative development, aging, responses to interventions, and the study of psychosocial and behavioral influences on health.
We saw much progress over the last years of the twentieth century. Today, we can view the progress and the future of womens health as a new mosaic: one that incorporates research, education of consumers and practitioners of health care, public health policy changes related to new information resulting from research, career development and advancement based upon the new paradigm, andcentral to all in the new mosaicwomen themselves. This new mosaic addresses emerging public health needs, scientific opportunities, and policy/advocacy concerns through the advancement of women as scientists, administrators, educators, and practitioners of health care.
Just a few years ago, "womens health" was thought of primarily as that involving the reproductive system. There was little attention given to other areas of womens health, such as heart disease, dental and oral health, autoimmune diseases, and menopause. Todays print and visual media show how that has changed over the past ten years. In the process, there has been an explosion of information about and attention to womens health. We have learned that normal parts of aging, such as menopause, should not be thought of as "diseases" and that prevention can help us to "age successfully" in a healthy manner.
In addition, initiatives to address the recruitment, retention, advancement, and reentry of girls and women into science and research fields, health care careers, health policy positions, and health administration are being developed and designed to attract girls and women into science.
During the past decade, the U.S. government has established new offices or programs within virtually every agency of the Department of Health and Human Services (HHS) to foster biomedical and behavioral research, health care, health policy studies, and other programs designed to address important issues related to the health of women. Today, although considerable scientific data are available on the natural biological and pathologic processes that affect women, substantial gaps in knowledge remain. Considerable efforts are required to further understand the effects of female sex hormones on cellular and organ systems and gender differences in health and disease. Such efforts have been under way for the past decade in the United States through the commitment of the National Institutes of Health (NIH) and its Office of Research on Womens Health (ORWH).
In September 1990, the ORWH was established at the NIH, the first HHS office dedicated to womens health issues. The NIH/ORWH is dedicated to expanding medical knowledge through scientific inquiry in order to ensure that every human being enjoys the highest attainable standard of health across the life span, from earliest childhood to the later years of life, without regard to sex or gender. At the NIH, the imperative to advance womens status through improved health is generating biomedical research designed to provide a better understanding of how such biological factors as sex and gender, as well as other factors including economic, genetic, geographic, and environmental differences, influence the causes, diagnosis, progression, treatment, and outcome of diseases for diverse populations. The womens health research agenda stresses the appreciation of the connections between early life activities and experiences that are antecedents for health or disease in later life, with important implications for the health of postmenopausal and elderly women.
In the 1990s, changes in thinking and perceptions transformed how scientific studies are designed and conductedincluding who participates in and who conducts such research. Changes in research study design to include sufficient men and women that an analysis by sex/gender of the results are important, as the data resulting from research must be applicable to both men and women of diverse racial and ethnic groups. Broader representation in the inclusion of participants in clinical research can then bring about improvements in public health policy, standards of health care practice, and individual perceptions about how best to preserve health across the life span of women with the understanding that such conclusions are based upon scientific facts.
Traditionally, with womens health viewed as synonymous with reproductive health, scant attention in research on women was given to issues beyond reproductive capacity, and the male body was viewed as the normative standard for clinical implications for both women and men. The expanded definition of womens health now fosters research on the totality of biological, genetic, biobehavioral, and environmental factors that influence health across the life span of females, from the prenatal period and birth, through childhood and adolescence and the adult years, to the menopausal, postmenopausal, elderly, and advanced years of life. The ORWH has utilized these expanded concepts to publish two research agendas on womens health with the full collaboration and participation of the advocacy and biomedical communities.

In the present fiscal year, priority has been given to the study of genetic, infectious, environmental, molecular, and/or hormonal factors as they contribute to multisystemic disorders affecting women, including mechanisms of sex differences in immunological responses and the development of surrogate markers and immune therapy. Prominent is a focus on diabetes, obesity, and cardiovascular diseases, with special emphasis on prevention, including nutrition, physical fitness, medical screenings, and oral and dental care. Attention is also being given to neurobiological and psychological risk and protective factors in the development of mental health and addictive disorders, as well as health consequences of violence and stress. Other areas of emphasis include reproductive health, such as menopause, fertility, and benign and malignant gynecologic conditions; care giving and health-related quality of life issues; infections, including sexually transmitted diseases; cancer; and complementary and alternative medicines and dietary supplements.
With the passage of the NIH Revitalization Act of 1993,6 which established the ORWH in law, the NIHs strengthened policies for the inclusion of women and minorities in clinical research studies became a matter of public law. The new law stipulated that NIH-supported studies must include women and minorities, unless there is compelling justification not to do so, including when such research might have a negative effect upon their health. The ORWH has the responsibility for ensuring the full implementation of these broader inclusion policies and for monitoring the inclusion of women and minorities in clinical trials. Since passage of the Revitalization Act of 1993, investigators have been required to enroll diverse cohorts of women that reflect the populations at risk or that share the demographic profile of those at risk for the condition under study. This mandate increases the challenges for recruitment and retention of women in clinical studies.79
To identify barriers to womens full participation in research, the ORWH convened a meeting in 1993 and issued a report, Recruitment and Retention of Women in Clinical Studies,7 as well as an Outreach Notebook for clinical investigators.8 The ORWH is also working to ensure that subpopulations of minority groups are adequately represented in research and that disparities in health among diverse populations of women are addressed through its research agenda and through its Strategic Plan to Address Health Disparities Among Diverse Populations of Women.10
A recent ORWH scientific workshop, "Science Meets Reality: Recruitment and Retention of Women in Clinical Studies and the Critical Role of Relevance," examined lessons of the past decade, continuing challenges to ensure that clinical research is relevant and targets scientific questions important to the public health, and emerging ethical and policy issues that present both challenges and opportunities for womens health research. Among issues raised were the need to appreciate how sex differences should be taken into account in the design of clinical research; the shift from the ethics of protectionism to the ethics of inclusion to concepts of justice in research; and the differences between clinical care and clinical research. Recommendations from the meeting will soon be published.

The leading causes of death for all women in this country are the same as for men: heart disease, lung cancer associated with smoking, and stroke. Yet, an American Heart Association Survey found that 61 percent of women consider breast cancer to be their greatest health threat as opposed to 7 percent for heart disease and 1 percent for stroke.11 Among women twenty-five to thirty-four years of age, only 17 percent named cardiovascular disease and stroke as the leading causes of death in women. The survey also reported that, when exercise stress tests are abnormal, about half as many women as men are recommended for further evaluation. Indeed, deaths for women from heart attacks, strokes, and other cardiovascular diseases (CVD) have exceeded those for men since 1984.12 Heart disease, stroke, and other CVD have only recently been recognized as serious health problems for women, despite the fact that women have a worse prognosis following a heart attack than men, due to older age and multiple health conditions, such as smoking-related conditions and diabetes, which pose major threats to public health in the United States.
Diabetes is closely connected with the issue of obesity, which is a major health problem for Americans of all racial and ethnic backgrounds. According to the Centers for Disease Control and Prevention, 33 percent of women in the United States, compared with 28 percent of men, are obese. Obesity is not only a serious threat to good health and longevity by itself, but it also puts individuals at risk for a host of other serious diseases and conditions, including cardiovascular disease and breast cancer. Obesity, for example, is one of strongest known risk factors for non-insulin dependent diabetes mellitus (NIDDM) and has a substantially higher prevalence among minority women. At present, almost 50 percent of adult minority women in the United States are obese, and many of these women will develop NIDDM and its comorbidities, which include heart disease, which is two to four times more common in the obese; stroke, which has a risk 2.5 times higher in the obese; hypertension; blindness; end stage renal disease; neuropathy; amputations; periodontal disease; and congenital malformations and mortality in infants who have obese mothers. Multidisciplinary approaches to research on obesity and its causes and sequella are current priorities for addressing this much too common threat to womens health.
| Successful Aging and Menopause: Findings from the Womens Health Initiative |

Menopause-related research supported by the NIH includes the well-known Study of Women Across the Nation (SWAN), a study of the natural history and progression of menopause among diverse populations of American women, as well as the Womens Health Initiative (WHI). Such large-scale studies are complemented by basic science research conducted throughout the NIHs constituent institutes. The WHI is a major fifteen-year research program to address the most common causes of death, disability, and frailty in postmenopausal women: cardiovascular disease, breast and colon cancer, and the fractures of osteoporosis. In July 2002, the investigators stopped the estrogen-plus-progestin (E+P) arm of the WHI clinical trial study after finding that the health risks associated with taking E+P outweighed the benefits. The results from the combination E+P arm of the WHI demonstrated that for every 10,000 women during one year, there were seven more heart attacks, eight more strokes, eight more cases of breast cancer, and eight more cases of pulmonary blood clots. There were some benefits, however, in that there were fewer cases of colon cancer and fewer osteoporotic fractures. The findings from this prematurely stopped E+P arm of the WHI seemed to show that, contrary to long-held clinical beliefs, E+P does not protect the heart and may, in fact, increase the risk of coronary heart disease as well as result in an increased risk of breast cancer.
The WHI Memory Study (WHIMS), an ancillary study of the WHI, examined how E+P or estrogen (E) alone affects womens cognition, including:
Results from WHIMS showed that women aged sixty-five and older taking E+P therapy had twice the rate of dementia, including Alzheimers disease (AD), compared with women who did not take the medication. The study also found that the combination therapy did not protect against the development of Mild Cognitive Impairment (MCI), a form of cognitive decline less severe than dementia.
Because the findings of this controlled clinical trial of E+P of the WHI were at odds with long-held beliefs, there was much controversy and concern among women and their physicians. However, the results of this clinical trial can and do provide information for women to be able to make informed decisions about their individual use of E+P.
Recognizing that the WHI clinical trial for E alone for menopausal hormone therapy is continuing, women must realize that the results from the E+P arm are not necessarily what will be found with the use of E alone, and there is no cause for alarm for women who are taking E. However, the Food and Drug Administration has now required new labels for all E and E+P products that indicate that the approved use of such hormones is for moderate to severe vasomotor symptoms associated with menopause or vulvar and vaginal atrophy associated with menopause, as well as the prevention of postmenopausal osteoporosis but only for women with significant risk of osteoporosis that outweighs the risks of the drug.15
The findings already released from the WHI and those anticipated in the future are prime examples of the importance of research to confirm or refute long-held beliefs related to womens health and health care that are not based upon scientific findings.

The BIRCWH program was developed in response to a need expressed during the process of formulating the womens health research agenda for a way to support interdisciplinary research bridging the completion of training with an independent career in research addressing womens health. Further, with the womens health community calling for less fragmentation of womens health care, the need to encourage interdisciplinary research as a foundation for integrated care seems of great importance. Further, there is a need to provide support for the development of interdisciplinary collaborations as well as a need to fund mechanisms for the development of womens health researchers in a mentored environment. Therefore, by creating a program that leads to interdisciplinary collaboration and mentoring for research, the stage may be also set to increase the likelihood of interdisciplinary collaboration for womens health care.
A unique feature of the BIRCWH program is the combination of support from the ORWH, which leads the BIRCWH initiative, and a number of NIH institutes and offices, including the National Institute of Child Health and Human Development (NICHD), which administers the program, and the Agency for Healthcare Research and Quality (AHRQ). By uniting cosponsors from a breadth of scientific areas, the program encourages researchers from different disciplines to apply their knowledge in new ways to study important topics in womens health, including sex (biologically based) and gender (socially based) factors in health and disease. The institutions that have received BIRCWH awards in 2000 and 2002 are listed in Table 1

In addition to collaborating with the NIH institutes and centers to foster womens participation and advancement in biomedical careers, the ORWH has worked with professional societies in science to identify routes to womens advancement. In conjunction with the American Society for Cell Biology (ACSB) and the NIEHS, ORWH convened a meeting called Achieving Xxcellence in Science (AXXS 99) to explore the roles of scientific societies in advancing science by building the careers of all women in science. It is the mission of AXXS to make women more visible and to advance their careers by increasing the recognition of their scientific accomplishments.
In June 2000, ORWH and ACSB sponsored a follow-up meeting to prioritize and refine the AXXS 99 initiatives and to develop action plans for implementing these initiatives, both within and across scientific societies. In fiscal year 2001, the ACTeam, a task force comprised of a core group of AXXS representatives, was formed to encourage and assist scientific societies and other professional organizations to implement and sustain initiatives to advance the careers of women in science. The ACTeam, working in cooperation with the Committee on Women in Science and Engineering (CWSE) of the National Academy of Sciences (NAS), held a one-and-a-half-day workshop in July 2002, that brought together representatives of more than forty-seven clinical societies to discuss ways to enhance the participation of women scientists in the clinical research workforce. The most recent meeting, AXXS 2002, evaluated the collected recommendations and proposed action items for a forthcoming report. Recommendations focused on initiatives and action items that clinical societies can adopt within their organizations to enhance womens advancement in the clinical research field; ways for clinical societies to disseminate successful strategies to advance womens careers; and ways that clinical societies can collaborate to promote womens contributions to their fields. Many clinical as well as basic science professional organizations and societies participated in addition to many components of the NIH. The AXXS project prepared and has distributed a summary of strategies presented and discussed at the meeting, which is also available on the AXXS website.18

As women increase in the general population and in entry into science and health care careers, their potential for contributions to advancements in science and health becomes an even more valuable resource for our nations and our world. Overcoming perceived as well as the very real inequities of opportunities for women to advance in scientific and health care careers must be an imperative for our efforts and for the new mosaic.
The path ahead requires us to stress the importance of including women of all races and cultures in science and health care and increasing career opportunities for womens leadership. We must convert scientific deficiencies into helpful knowledge through research, utilizing multidisciplinary strategies to eliminate fragmentation of intellectual pursuits as well as health care delivery. And we must ensure a comprehensive approach to the health and well-being of women in the twenty-first century.
In the future, we look forward to developing a focused research and education program to expand the science base of accurate information, followed by dissemination of that information about the health and the diversity of women that make up our nations. Integral to this effort is the incorporation of such information into the education and training of future health professionals, regardless of their discipline. Our ultimate goal is for science, and therefore for all health professionals, to provide the wisdom necessary to provide sex- and gender-appropriate care for those seeking to preserve their health or cure their illnesses. Women, as well as men, and their families and communities can and will benefit from this approach.
