DESCRIPTION:Cohort studies follow people over time to investigate causes a
 nd risk factors of disease and other health-related outcomes. They have pl
 ayed key roles in the history of epidemiology and public health\, and cont
 emporary cohorts such as the UK Biobank are vital sources of observational
  data for many different fields of medical research. Large cohort studies 
 assemble many different types of data on participant health\, behaviour\, 
 environment and genetics\, enabled by efficient methods of recruitment\, m
 easurement\, and follow-up through administrative datasets. However\, thes
 e methodological features of cohort studies also present challenges for da
 ta analysis\, particularly selection biases\, measurement error\, and ques
 tions of causality. This lecture will discuss the successes of and challen
 ges for contemporary cohort studies\, and some of the ways in which the ch
 allenges can be met.\n\nDr Benjamin Cairns is a Nuffield Department of Pop
 ulation Health Senior Research Fellow\, working in the MRC Population Heal
 th Research Unit. His research trajectory started outside of health scienc
 es\, studying mathematical models in ecology and conservation. He then joi
 ned the Cancer Epidemiology Unit at the University of Oxford\, and has sin
 ce worked on epidemiological studies in cohorts such as the Million Women 
 Study and the UK Biobank. His current research interests are in aortic val
 ve disease and other cardiovascular diseases\, multimorbidity\, and resear
 ch methods in epidemiology.\n\nThis talk is given as part of the graduate 
 programmes in Evidence-Based Healthcare\, Oxford University Department for
  Continuing Education. \nSpeakers:\nDr Ben Cairns (Nuffield Department of 
 Population Health)
