Obesity is recognized as a risk factor for multiple chronic diseases. Yet, it is unclear whether obesity is also associated with an increased risk of nonfatal unintentional injury. A population-based survey was conducted among adults aged ≥18 years from January 1999 through October 2000.

We observed a linear dose-response trend among women. An estimated 7.0% of underweight individuals (BMI
