Based at the University of Sheffield, the Yorkshire Health Study is Yorkshire’s largest health study. This study provides:


        -  up-to-date information on the health needs of people in Yorkshire


-  a large efficient facility to identify, recruit and follow up participants for research (including data linkage to HES)



The Yorkshire Health Study is a longitudinal observational regional health study collecting health information on the residents from the Yorkshire and Humberside region in England.

The study aims to inform NHS and local authority health-related decision making in Yorkshire.


The study encourages researchers to utilize the sample through the embedding of randomized controlled trials, other controlled trials and qualitative studies. To access the anonymized data or use the sample to recruit participants to studies, researchers should contact Annette Haywood  (


Between 2010 and 2012, 27,806 adults in South Yorkshire filled in our health questionnaire. Data were collected on current and long-standing health, health care usage and health-related behaviours, with a particular focus on weight and weight management. The majority of individuals also gave consent for record linkage with routine clinical data (disease diagnosis, medication use and health care usage).


In 2014, the study expanded to the whole of the Yorkshire and Humberside region. To date over 73,000 adults have completed our health questionnaire.

How we are funded


We receive funding from the NIHR CLAHRC -South Yorkshire, NIHR CLAHRC Yorkshire & Humber, and the University of Sheffield (ScHARR)


How we are run


The day to day running of the study is the responsibility of the Yorkshire Health Study Management Committee & Review Panel. This committee comprises Professor Liddy Goyder (Chief Investigator),  Dr Clare Relton, Annette Haywood (Project Manager), Professor Jon Nicholl, Annabel Crum (Data manager), Martin Fox (Project Coordinator)

"The YHS has collected such a wide range of information on health outcomes and behaviours in such quantity that it stands out when compared to other available resources. As the YHS continues to grow and gains further waves of data, it will become one of the main resources for health-related research in England."

 Dr Mark Green, University of Liverpool


"We used the Yorkshire Health Study (previously the South Yorkshire Cohort) as it is a wonderfully rich dataset. We were able to account for the potentially confounding effects of a number of socio-demographic variables, and explore the potentially mediating effects of having a long-term condition. The inclusion of these variables in our analysis lends more credibility to the findings".
