A new study says Nebraska require $454 million in extra medical spending annually tied to obesity.

The national survey was done by researchers from the federal Centers for Disease Control and Prevention, and RTI International, a North Carolina research company.

The survey estimates about half of the states' sums are paid by taxpayers through medical assistance programs. It also estimates about 5.8-percent of Nebraska's population qualifies as obese.

The state is to be published Friday in the journal Obesity Research. It estimates that $75 billion in annual medical expenditures nationally may be attributed to adult obesity.

The study's researchers say results show obesity imposes a substantial drain on health care resources across states, and that roughly one-half of the expenditures are financed by Medicare and Medicaid.
