Revisiting the obesity paradox in health care expenditures among adults with diabetes.
This AHRQ-authored study explored and examined an obesity paradox identified by recent studies which suggests that in people without diabetes mortality risk increases with weight and in people with diabetes mortality risk decreases with weight. The researchers assessed changes in the association between body mass index (BMI) and health care expenditures in populations with diabetes and without diabetes while controlling for confounding risk factors. The researchers found that there is no obesity paradox; it is the result of statistical biases, and the study concluded that obesity in people with diabetes does not save costs.

Explaining the obesity paradox in healthcare utilization among people with type 2 diabetes.
The authors sought to examine changes in the relationship between BMI and number of visits in diabetic vs nondiabetic populations, controlling for confounding risk factors. Using MEPS data, they found that the obesity paradox does not exist at the utilization level and is due to the presence of statistical biases such as confounding and reverse causation.

The burden of obesity on diabetes in the United States: Medical Expenditure Panel Survey, 2008 to 2012.
The researchers analyzed the risk of developing diabetes and the annual cost of diabetes for a US general population. Their results suggested that the annual health care expenditure differentials between those with and without diabetes of age 50 years were the highest for individuals with class II ($12,907) and class III ($9,703) obesity.
