Obesity is associated with postural balance on unstable surfaces but not with fear of falling in older adults.

Background: There are inconsistent findings regarding the relationship between body mass index (BMI), fear of falling and body balance, especially on unstable surfaces.

Objectives: To investigate whether obesity is associated with worse postural balance and fear of falling in older adults.

Methods: A cross-sectional study was conducted with 201 older adults, classified as normal weight, overweight, or obese according to BMI.
