Cohort details




The study was piloted in 2010 in the South Yorkshire region (Sheffield, Rotherham, Doncaster, Barnsley and their surrounding areas) and parts of North Derbyshire. Around 90 GP surgeries in the region were asked to take part in the study (known then as the 'South Yorkshire Cohort'). Almost half (n= 43) took part and sent out questionnaires to their patients aged 16 to 85. At this stage, a rudimentary online questionnaire was also available. For our first wave of data collection (2010-2012), a total of 27,806 questionnaires were returned (a response rate of 15.9%). Our second wave of data collection (2013-2015) followed up all those from wave 1 who had agreed to be contacted. Then in 2014, the study was renamed the 'Yorkshire Health Study' and extended to the whole of the Yorkshire and Humber region. To date, over 73,000 adults have completed our health questionnaires.
