GP supply and obesity

H. Gravelle, S. Morris

Research output: Book/ReportCommissioned report


We investigate the relationship between GP supply and body mass index (BMI) in England. Individual level BMI is regressed against area whole time equivalent GPs per 1,000 population plus individual and area level covariates. Using IV models we find that a 10% increase in GP supply is associated with a mean reduction in BMI of around 1 kg/m 2 (around 4% of mean BMI). Our study suggests that better primary care in the form of reduced list sizes per GP can improve the management of obesity.
