Over the past fifteen years, the Canadian population has undergone increasing cultural diversification. Many researchers have investigated the role of culture with respect to social and health services. Most studies confirm the fact that increased cultural diversification related to immigration challenges the public health system in many ways. Certain groups, such as economically challenged immigrant women, may pose even greater problems to the health system. While these individuals are in relatively good health upon arrival to Canada, there is a need to ensure that adequate health promotion as well as disease prevention strategies are instituted. It is important to examine the concepts of health promotion and disease prevention through a cultural perspective. Little research has been done in this area. Concepts of promotion and prevention as they are understood by immigrants may not always coincide with North American or European definitions. Therefore, it is essential to consider life conditions that surround potential health promotion and prevention behaviors of immigrants. Empowerment, economic integration and acculturation are among the many factors that need to be taken into account when studying immigrants' health promotion behavior. Here, we present a critical analysis of current knowledge in this field. This is followed by research recommendations aimed at facilitating the development of health promotion and prevention strategies that are appropriate to the needs of Canadian, and more specifically of immigrant women in Québec.
