Obesity rates are high among all age groups, including older adults. Obesity negatively affects health and functional ability, increasing the risk for nursing home (NH) admission. The current study examines trends over 11 years in moderate to severe obesity rates among NH residents. A generalized least squares regression model for panel data was used to test the effect of time (years) on the rates. A significant increase in rates and significant variation in rates were observed. Little research has focused on the issue of obesity in NHs. High and increasing rates and variation in rates raise questions on demand and access to NH care for obese older adults. Additional research is needed to consider factors other than time that may affect NHs’ ability to admit moderate to severely obese individuals. Understanding these trends will help NHs prepare for future demand, ensure equal access, quality care, and financing of services.
