Seminar – 11 May 2016 – Professor Terence Dwyer
May 11, 2016 @ 12:00 pm - 1:00 pmFree
All are invited to the CEDAR/MRC Epidemiology Seminar:
The contribution of physical activity to increased life expectancy
Recently, Terry Dwyer and his team reported their findings on the association of pedometer measured steps and mortality from a fifteen year follow up of these cohorts (Dwyer, T., et al. (2015). “Objectively Measured Daily Steps and Subsequent Long Term All-Cause Mortality: The Tasped Prospective Cohort Study.” PloS one 10(11): e0141274).
In a combined cohort of almost 3,000 subjects among whom 220 deaths occurred, a 40% reduction in mortality for those taking the highest number of steps compared to the lowest was observed. This was the first evidence from a population based cohort that PA measured objectively was inversely associated with mortality.
In this talk he will review the evidence on the relationship between PA, predominantly measured by questionnaire, and major health outcomes and put into context what this new data using an objective measure of PA adds to the overall picture. In describing how the complex puzzle of PA and health is developing he will identify what deficiencies in the evidence need to be addressed before greater certainty about the causal nature of the association can be reached.
About Professor Dwyer
Professor Terence Dwyer is a non-communicable disease epidemiologist with extensive experience in the conduct of cohort and case control studies with a focus on infant and child health.
Professor Dwyer’s research on Sudden Infant Death Syndrome and sleeping position was recognised by the NHMRC, Australia, as one of the thirteen most important contributions to medical research by Australia in the 20th century. This work was mainly conducted in the Tasmanian Infant Health Survey which enrolled 11,000 infants between 1988 and 1995.
Professor Dwyer currently leads two large global cohort collaborations. The first follows around 40,000 subjects who were first measured at school age, now moving into their 5th and 6th decades, to estimate separate effects of childhood physical and lifestyle characteristics on risk of major adult diseases such as type 2 diabetes and cardiovascular disease. The second is the International Childhood Cancer Cohort Consortium (14C), a collaboration of birth cohorts in more than ten countries. It aims to obtain prospective evidence on the causes of childhood cancer by assembling data on 1 million mothers and babies who will be followed through childhood.
