'Health equity through action on the social determinants of health': taking up the challenge in nursing.

Reducing health inequities is a priority issue in Canada and worldwide. In this paper, we argue that nursing has a clear mandate to ensure access to health and health-care by providing sensitive empowering care to those experiencing inequities and working to change underlying social conditions that result in and perpetuate health inequities. We identify key dimensions of the concept of health (in)equities and identify recommendations to reduce inequities advanced in key global and Canadian documents. Using these documents as context, we advocate a 'critical caring approach' that will assist nurses to understand the social, political, economic and historical context of health inequities and to tackle these inequities through policy advocacy. Numerous societal barriers as well as constraints within the nursing profession must be acknowledged and addressed. We offer recommendations related to nursing practice, education and research to move forward the agenda of reducing health inequities through action on the social determinants of health.
