Looking forward to the next 15 years: innovation and new pathways for research in health equity.

Since our launch in 2002, the International Journal for Equity in Health (IJEqH) has furthered our collective understanding of equity in health and health services by providing a platform on which academics and practitioners can share their work. Today, we celebrate our fifteenth anniversary with an article collection that presents a call for new and novel research in equity in health and we invite our authors to use new approaches and methods, and to focus on emerging areas of research related to health equity in order to set the stage for the next fifteen years of health equity research.Our anniversary issue provides a platform for expanding the conceptualization, diversity of populations and study designs, and for increasing the use of novel methodologies in the field. The IJEqH has helped to support the wider group of researchers, policymakers and practitioners with a commitment to social justice and equity but there is still more to do. With the help of the highly committed editorial team and editorial board, the innovative work of researchers worldwide, and the countless of hours dedicated by hundreds of reviewers, we are confident in the IJEqH's ability to continue supporting the dissemination of health equity research for years to come.
