Abstract

OBJECTIVES:

This study examined whether body mass index (BMI) or change in BMI raises the risk of disability in adulthood.

METHODS:

The relation between BMI and upper- and lower-body disability was examined among adult subjects from a national longitudinal survey (n = 6833). Tobit regression models were used to examine the effect of BMI on disability 10 and 20 years later.

RESULTS:

Obesity (BMI > or = 30) at baseline or becoming obese during the study was associated with higher levels of upper- and, especially, lower-body disability. In persons who began the study with a BMI of 30 or more and became normal weight, disability was not reduced. Underweight persons (BMI < 18.5) also manifested higher disability in most instances.

CONCLUSIONS:

Disability risk was higher for obese persons, but overweight was not consistently associated with higher disability.
