Dr. Demers will present on the impact of shift work on human health in the context of our modern 24-hour society. The body of literature that led to the International Agency for Research on Cancer to classify shift work with circadian disruption as a probable human carcinogen (2A) in 2007 will be discussed, as will the evidence published since this initial classification was made. The talk will conclude with a discussion of possible mechanisms that may lead from circadian disruption to carcinogenesis, and how we can use these hypothesized mechanisms to identify prevention strategies for reducing the burden of shift work on human health.
