Frequently Asked Questions
Why is BMI different for seniors?
Older adults with BMI 22-27 have the lowest mortality. Being too thin (BMI <22) increases fall risk, frailty, and death more than being slightly overweight.
Is BMI accurate for elderly people?
BMI has limitations at any age, but especially for seniors due to muscle loss, bone density changes, and height shrinkage. Waist circumference and functional assessments supplement BMI.
