unnecessary surgical intervention and inappropriate medication. 104. Statistical data on health are often not systematically collected, disaggregated and analysed by age, sex and socio-economic status and by established demographic criteria used to serve the interests and solve the problems of subgroups, with particular emphasis on the vulnerable and marginalized and other relevant variables. Recent and reliable data on the mortality and morbidity of women and conditions and diseases particularly affecting women are not available in many countries. Relatively little is known about how social and economic factors affect the health of girls and women of all ages, about the provision of health services to girls and women and the patterns of their use of such services, and about the value of disease prevention and health promotion programmes for women. Subjects of importance to women’s health have not been adequately researched and women’s health research often lacks funding. Medical research, on heart disease, for example, and epidemiological studies in many countries are often based solely on men; they are not gender specific. Clinical trials involving women to establish basic information about dosage, side-effects and effectiveness of drugs, including contraceptives, are noticeably absent and do not always conform to ethical standards for research and testing. Many drug therapy protocols and other medical treatments and interventions administered to women are based on research on men without any investigation and adjustment for gender differences. 105. In addressing inequalities in health status and unequal access to and inadequate health-care services between women and men, Governments and other actors should promote an active and visible policy of mainstreaming a gender perspective in all policies and programmes, so that, before decisions are taken, an analysis is made of the effects for women and men, respectively. Strategic objective C.1. Increase women’s access throughout the life cycle to appropriate, affordable and quality health care, information and related services Actions to be taken 106. By Governments, in collaboration with non-governmental organizations and employers’ and workers’ organizations and with the support of international institutions: (a) Support and implement the commitments made in the Programme of Action of the International Conference on Population and Development, as established in the report of that Conference and the Copenhagen Declaration on Social Development and Programme of Action of the World Summit for Social Development 15/ and the obligations of States parties under the Convention on the Elimination of All Forms of Discrimination against Women and other relevant international agreements, to meet the health needs of girls and women of all ages; (b) Reaffirm the right to the enjoyment of the highest attainable standards of physical and mental health, protect and promote the attainment of this right for women and girls and incorporate it in national legislation, for example; review existing legislation, including health legislation, as well as policies, where necessary, to reflect a commitment to women’s health and to ensure that they meet the changing roles and responsibilities of women wherever they reside; -38-
