(V) ABSTRACT Menopause is one of the major biological events to occur in a women's lifetime. Although it is considered as a normal physiological change, its effects often have social and psychological implications. (Morse et al 1993). At present there is minimal information regarding the experience women face during the menopause, particularly in multicultural societies. Currently, Morse et al (1993) from the University of Wollongong are investigating the health experiences of middle aged Italian women in the Illawarra area of N.S.W. The aims of their research are; • To identify the groups menopausal experiences and attitudes, and compare the findings with those of the dominant culture (Anglo- Australians); • To examine the nutrition of these groups and to relate dietary factors to the type and severity of reported menopausal changes; • Further to consider the role if any, of acculturation of this group within a different dominant host culture that may influence the incidence and character of menopause related morbidity. (Morse et al 1993) At present evidence is mounting that nutritional intake may effect menopausal symptoms. This evidence is focused on phvtoestrogens and the oestrogenic activity of certain foods ( Wilcox et al 1990). (VI) The purpose
