Interdisciplinary research is key to understanding sex differences: report from the Society for Women's Health Research Meeting on understanding the biology of sex differences.

Progress in sex-based biology, the study of biological and behavioral differences between males and females, and the impact of those differences on health and disease will require collaboration across research disciplines and medical specialties and among all research approaches, from molecular biology to epidemiology. The importance of sex-based biology to healthcare necessitates a bench-to-bedside approach that is built on integration of research findings from studies at the cellular level, in animals, and in human subjects. Barriers to interdisciplinary collaborations are being addressed in a variety of ways by public and private funders. The J.D. and C.T. MacArthur Foundation supports interdisciplinary research networks that address broad questions in health and behavior. The National Institute of Mental Health supports cross-disciplinary research networks investigating the hypothalamic-pituitary-adrenal network. The National Institute of Child Health and Human Development offers grants for Building Interdisciplinary Research Careers in Women's Health. The National Science Foundation Directorate for Biological Sciences sponsors Research Coordination Networks in Biological Sciences. Among the challenges faced by interdisciplinary research programs are appropriate peer review, career advancement for young investigators with interdisciplinary training, and acceptance of interdisciplinary research reports by high-quality scientific publications.
