The adult obesity rate in Thurston County is 43.3%, the highest of any county in Nebraska and one of the highest in the United States.

Adults in the county are also less likely to engage in physical activities than the typical Nevadan or American. The area’s inactive lifestyles are likely attributable in part to environmental conditions. Just 8.5% of the county population has access to places for physical activity like parks and gyms.
