Responding to and tackling obesity and overweight in South Yorkshire represents a major public health challenge.  The increase in body fat associated with obesity is linked with serious health complications including Type II diabetes, stroke, cancer and osteoarthritis.  A reduction in weight of 5 – 10% is associated with an improvement in the risk of these adverse health conditions.

The recently published Foresight report1 suggested that on current trends, around 50% of the adult population of England could be obese by 2050.  Currently South Yorkshire has rates of obesity similar to the national average.  The NHS therefore requires well designed, robust and up to date evidence in relation to patterns of (health and social care) service use and the scale, costs and acceptability of the various self-care activities currently being utilised by overweight and obese individuals.  More generally, there is a dearth of longitudinal data tracking the ‘natural history’ of overweight and obese individuals in their attempts to manage weight. 

NIHR CLAHRC for South Yorkshire funding is being used to set up a cohort of adults in South Yorkshire, to be tracked over the course of the CLAHRC.  The primary purpose of this study will be to inform NHS provision of healthcare with regards to the management and self management of obesity and chronic conditions and the effect of particular variables on health outcomes associated with obesity and its self management.  The secondary purpose of the cohort is to provide a cohort multiple trials facility which can be used to trial the acceptability, clinical and cost effectiveness of potential weight and chronic condition self/management interventions.  This will enable faster identification of potentially helpful interventions in this area (if they are already being used by patients) and a faster translation of these interventions being tested pragmatically, as identified by the Cooksey Review (2006)2.
