McMaster Optimal Aging Portal


(Last updated 18 April 2015)

The McMaster Optimal Aging Portal (hereafter referred to as the Portal) provides direct access to trusted, evidence-based information about optimal aging. The Portal is maintained by McMaster University.

The Portal aims to be a trusted voice on optimal aging for citizens, clinicians, public health professionals and policymakers. It includes three types of content for citizens: Evidence Summaries (key messages from scientific research that are ready to be acted on); Web Resource Ratings (evaluations that tell you whether free health resources on the internet are based on scientific research); and Blog Posts (commentaries on what the scientific research on aging actually means for you, and about why good science matters). Additional content for professionals includes ratings of and links to the best scientific evidence on clinical, public health and health system questions. The Portal also provides opportunities to choose how to search the content, sign up for email alerts, and learn about and get engaged in a variety of knowledge translation activities such as citizen panels, debates and public talks. More details about the Portal and its features are available in the ‘About’ section and the ‘Help’ section of this Website.
