Technical Summary

Overweight and obesity have been found to be associated with several diseases such as diabetes, cardiovascular diseases and certain types of cancer. Furthermore obese patients more frequently experience non-life threatening disease like osteoarthritis and other musculoskeletal diseases. This study seeks to examine whether the increased disease frequency in obese patients compared to non-obese patients results in an increased healthcare resource utilisation defined as higher rates of GP contacts, use of prescription medication or hospital admission.

The cohort consists of patients registered in the CPRD who have a current registration date prior to 01.01.2010 and acceptable data as defined by CPRD. Each patient is followed from an individual baseline (latest date of BMI measurement between 01.01.2008 and 01.01.2010 or 01.01.2009 if no BMI is registered within this period) until end of follow-up (minimum of death date, transfer out date or 30.09.2014). Patients below 18 years of age at baseline are excluded. Rates of the three endpoints are calculated and the rates for obese and non-obese patients are compared using Poisson regression analysis. Sensitivity analyses concerning the group of patients without a registered BMI will be performed.
