Demographic, epidemiological and socio-economic trends in developing countries are creating new mortality and morbidity patterns for both women and men. Women's health needs will increasingly include problems beyond reproduction, and health interventions must take into consideration the important characteristics of women's lives that affect their ability to address these problems. Meeting the changing health needs of women in developing countries will require more comprehensive health interventions guided by innovative, interdisciplinary research. A broader conceptualization of women's health needs, and the constraints and opportunities associated with meeting those needs, is necessary to avoid overly simplistic assigning of responsibility, which can lead to blaming organizations, disciplines and individuals, including women themselves, for persistent health problems and underutilization of existing services.
